Accountants and Auditors in the US 1850-2016

Description

Accountants and auditors as a percent of the US labor force 1850 to 2016 updating the analysis in Wyatt and Hecker (2006).

Usage

data(AccountantsAuditorsPct)

Format

a numeric vector of length 30 giving the percent of the US labor force in "Accounting and Auditing" each decade from 1850 to 2010 except for 1940 plus each year between 2011 and 2016.

Source

This is based primarily on data extracted from the Integrated Public Use Microdata Series on 2018-09-01 with the computations documented in a vignette by this title in the Ecfun package.

This updates the data on Accountants and Auditors in Wyatt and Hecker (2006). They relied primarily on data extracted from the Integrated Public Use Microdata Series. This follows the same methodology with two modifications:

1. IPUMS provided no data for 1940. Wyatt and Hecker (2006) used Historical Statistics of the United States, Colonial Times to 1970, Bicentennial Edition, part 1 (U.S. Department of Commerce, Bureau of the Census, 1975) for 1910-1940. The current data set uses that source only for 1040.

2. The IPUMS numbers showed an extreme jump from 1850 to 1860 followed by an even more extreme drop to 1870. The numbers in Sobek (2006) showed essentially the same behavior. Specifically, Sobek (2006) estimated the number of accountants and auditors in the US in those three years as 700, 1700, and 1200, and the labor force as 5277000, 8160800, and 12004200. These numbers give accountants and auditors as 0.013, 0.021, and 0.010 percent of the labor force, respectively for those three years. These numbers portray an incredible increase in the employment of accountants and auditors between 1850 and 1860 followed by a shocking decline the following decade. If, however, we swap the 1700 and 1200 between 1860 and 1870, the percentages become quite stable: 0.013, 0.015, and 0.014 percent, respectively.

We use these latter numbers, even though the uncorrected numbers seem more consistent with the numbers obtained from IPUMS.

Growth of CRAN

Description

Data casually collected on the number of packages on the Comprehensive R Archive Network (CRAN) at different dates.

NOTE: This could change in the future. See Details below.

Usage

data(CRANpackages)

Format

A data.frame containing:

Version

an ordered factor of the R version number primarily in use at the time. This was taken from archives of the major releases at https://svn.r-project.org/R/branches/R-1-3-patches/tests/internet.Rout.save, ... https://svn.r-project.org/R/branches/R-3-1-branch/tests/internet.Rout.save

Date

an object of class Date giving the date on which the count of the number of CRAN packages was determined.

Packages

an integer number of packages on the CRAN mirror checked on the indicated Date.

Source

A factor giving the source (person) who collected the data.

Details

This seems to provide the most widely available source for data on the growth of CRAN, manually recorded by John Fox and Spencer Graves. For a discussion of these and related data, see Fox (2009).

For more detail, see the CRAN packages data on GitHub maintained by Hadley Wickham. This contains the description file of every package uploaded to CRAN prior to the date of Hadley's most recent update. The current maintainer of the Ecdat and Ecfun packages would consider contributions along the following lines:

1. It might be nice to have a more complete dataset or datasets showing CRAN growth. This might include code fitting multiple models and predicting future growth with error bounds computed using Bayesian Model Averaging. These model fits might make an interesting addition to the examples in this help file. With a little more effort, it might make an interesting note for R Journal. Functions written to fit those models might be added to the Ecfun package.

2. It might be nice to have a function in Ecfun to download the CRAN packages data from GitHub and convert it to a format suitable for updating this dataset.

The current maintainer for Ecdat and Ecfun (Spencer Graves) might be willing to accept code and documentation for this but is not ready to do it himself at the present time.

Files containing financial crisis data

Description

FinancialCrisisFiles is an object of class financialCrisisFiles created by the financialCrisisFiles function in Ecfun. It describes files containing data on financial crises downloadable from https://web.archive.org/web/20150419090824/http://www.reinhartandrogoff.com/data/browse-by-topic/topics/7.

NOTE: When this dataset was created it was downloaded from http://www.reinhartandrogoff.com/data/browse-by-topic/topics/7. However, it was "Not Found" in testing on 2020-02-09. Fortunately the data are still available on the Internet Archive.

Usage

data(FinancialCrisisFiles)

Details

Reinhart and Rogoff (http://www.reinhartandrogoff.com) provide numerous data sets analyzed in their book, "This Time Is Different: Eight Centuries of Financial Folly". Of interest here are data on financial crises of various types for 70 countries spanning the years 1800 - 2010, downloadable from http://www.reinhartandrogoff.com/data/browse-by-topic/topics/7/.

Version 0.2-3 of the Ecfun package included a function financialCrisisFiles that produced a list of class financialCrisisFiles describing four different Excel files in very similar formats with one sheet per Country and a few extra descriptor sheets. This data object FinancialCrisisFiles was produced by that function. That function required the gdata package, and users of that package were advised to terminate use of it, because it was scheduled to be removed from CRAN along with all packages that used it. Since Reinhart and Rogoff seemed not to be actively maintaining that dataset, there seemed little need to do the work required to make the Ecfun::financialCrisisFiles work without gdata, so it was removed from Ecfun version 2.0-4.

Value

FinancialCrisisFiles is a list with components carrying the names of files to be read. Each component is a list of optional arguments to pass to do.call(read.xls, ...) to read the sheet with name = name of that component. (This read.xls was part of the gdata package, which may no longer be available on CRAN.)

This corresponds to the files downloaded from http://www.reinhartandrogoff.com/data/browse-by-topic/topics/7/ in January 2013 (except for the fourth, which was not available there because of an error with the web site but instead was obtained directly from Prof. Reinhart).

Evolution of occupational distribution in the US

Description

Proportion of the US population in each of the 283 OCC1950 occupation codes for each year in the Integrated Public Use Microdata Series (IPUMS) - US database.

Usage

data("OCC1950")

Format

A matrix with one row for each of 281 OCC1950 occupation codes in IPUMS-US and one column for each year in their dataset as of 2020-03-17, being c(1850:1880, 1900:2000, 2001:2016).

Details

This dataset was created using the code in the IPUMS vignette in the Ecfun package using tapply(HHWT, IPUMSdata[c("OCC1950", "YEAR")], sum), then normalizing so the total for each year was 1.

In fact a plot of the sums for each year of HHWT were close to the USGDPpresidents$population.K*1000 except for 1970, when they were double.

Universe Note from the IPUMS documentation for their variable OCC1950: "New Workers" are persons seeking employment for the first time, who had not yet secured their first job.

OCC1950 applies the 1950 Census Bureau occupational classification system to occupational data, to enhance comparability across years. For pre-1940 samples created at the University of Minnesota, the alphabetic responses supplied by enumerators were directly coded into the 1950 classification. For other samples, the information in the variable OCC was recoded into the 1950 classification. Codes above 970 are non-occupational responses retained in the historical census samples or blank/unknown. The design of OCC1950 is described at length in "Integrated Occupation and Industry Codes and Occupational Standing Variables in the IPUMS.". The composition of the 1950 occupation categories is described in detail in U.S. Bureau of the Census, Alphabetic Index of Occupations and Industries: 1950 (Washington D.C., 1950).

In 1850-1880, any laborer with no specified industry in a household with a farmer is recoded into farm labor. In 1860-1900, any woman with an occupational response of "housekeeper" enters the non-occupational category "keeping house" if she is related to the head of household. Cases affected by these imputation procedures are identified by an appropriate data quality flag (present in the raw IPUMS data but ignored for this summary).

A parallel variable called OCC1990, available for the samples from 1950 onward, codes occupations into a simplified version of the 1990 occupational coding scheme." [OCC1990 was ignored for the present purposes, because it is not coded for data prior to 1950.]

NOTE: In the 2020-03-17 extraction, there were 283 OCC1950 codes documented, but only 291 of them were actually in the data I got. The codes for "Not yet classified" and "New Workers" were not used.

Details

This is extracted from Table 6.16 of the National Income and Product Accounts (NIPA) compiled by the Bureau of Economic Analysis of the United States federal government. This table comes in four parts, A (1929-1947), B (1948-1987), C (1987-2000), and D (1998-present). Parts A, B, C and D contain different numbers of data elements, but the first five have the same names and are the only ones used here. The overlap between parts C and D (1998-2000) have a root mean square relative difference of 0.7 percent; there were no differences between the numbers in the overlap period between parts B and C (1987).

This was created using the following command:

demoDir <- system.file('demoFiles', package='Ecdat') demoCsv <- dir(demoDir, pattern='csv$', full.names=TRUE)

US GDP per capita with presidents and wars

Description

It is commonly claimed that Franklin Roosevelt (FDR) did not end the Great Depression: World War II (WW2) did. This is supported by the 10.6 percent growth per year in real Gross Domestic Product (GDP) per capita seen in the standard GDP estimates from 1940 to 1945. It is also supported by the rapid decline in unemployment during the war.

However, no comparable growth spurts in GDP per capita catch the eye in a plot of log(GDP per capita) from 1790 to 2015, whether associated with a war or not, using data from Measuring Worth. The only other features of that plot that seem visually comparable are the economic disaster of Herbert Hoover's presidency (when GDP per capital fell by 10 percent per year, 1929-1932), the impressive growth of the US economy during the first seven years of Franklin Roosevelt's presidency (6.4 percent per year, 1933-1940), and the post-World War II recession (when GDP per capita fell by 7.9 percent per year, 1945-1947). (NOTE: The web site for Measuring Worth, https://measuringworth.com/ still works, but has not always been maintained to current internet security standards. Therefore, the link is provided here in text but not as a link.)

Closer inspection of this plot suggests that the US economy has generally grown faster after FDR than before. This might plausibly be attributed to "The Keynesian Ascendancy 1939-1979".

Unemployment dropped during the First World War as it did during WW2. Comparable unemployment data are not available for the U.S. during other major wars, most notably the American Civil War and the Mexican-American War.

This data set provides a platform for testing the effects of presidency, war, and Keynes. It does this by combining the numbers for US population and real GDP per capital dollars from Measuring Worth with the presidency and a list of major wars and an estimate of the battle deaths by year per million population. (As noted above, the web address for measuring worth, https://measuringworth.com/, often gives security warnings but still seems to provide the data as before.)

US unemployment is also considered.

Usage

data(USGDPpresidents)

Format

A data.frame containing 259 observations on the following variables:

Year

integer: the year, c(seq(1610, 1770, 10), 1774:2015)

CPI

Numeric: U. S. Consumer Price Index per Officer and Williamson (2022), starting in 1774. Average 1982-84 = 100.

GDPdeflator

numeric: Implicit price deflators for Gross Domestic Product with 2012 = 100 per Johnston and Williamson.

population.K

integer: US population in thousands.

Population figures for 1610 to 1780 came from Springston (2013). The rest came from Johnston and Williamson. (The early population figures reflect only the European settlers in the British colonies that eventually became the US.)

realGDPperCapita

numeric: real Gross Domestic Product (GDP) per capita in 2012 dollars since 1790.

Real GDP = population.K*realGDPperCapita, in thousands.

Current or nominal GDPperCapita = realGDPperCapita*GDPdeflator/100.

executive

ordered: Crown of England through 1774, followed by the "ContinentalCongress" and the "ArticlesOfConfederation" until Washington, who became President under the current base constitution in 1789. Two nineteenth century presidents are not listed here (William Henry Harrison and James A. Garfield), because they died so soon after inauguration that any contribution they made to the economic growth of the nation might seem too slight to measure accurately in annual data like this; their contributions therefore appear combined with their replacements (John Tyler and Chester A. Arthur, respectively). The service of two other presidents is officially combined here: "Taylor-Fillmore" refers to the 16 months served by Zachary Taylor with the 32 months of Millard Fillmore. These modifications make Barack Obama number 41 on this list, even though he's the 44th president of the U.S.

war

ordered: This lists the major wars in US history by years involving active hostilities. A war is "major" for present purposes if it met two criteria:

(1) It averaged at least 10 battle deaths per year per million US population.

(2) It was listed in one of two lists of wars: For wars since 1816, it must have appeared in the Correlates of War. For wars between 1790 and 1815, it must have appeared in the Wikipedia "List of wars involving the United States".

The resulting list includes a few adjustments to the list of wars that might come readily to mind for people moderately familiar with US history.

A traditional list might start with the American Revolution, the War of 1812, the Mexican-American war, the Civil War, the Spanish-American war, World Wars I and II, Korea, and Vietnam. In addition, the Northwest Indian War involved very roughly 30 battle deaths per year per million population 1785-1795. This compares with the roughly 100 battle deaths per year 1812-1815 for the War of 1812.

For present purposes, the Spanish-American War is combined with the lesser-known American-Philippine War: The latter involved 50 percent more battle deaths but over a longer period of time and arguably with less impact on the stature of the US as a growing world power. However, its magnitude suggest it might have impacted the US economy in a way roughly comparable to the Spanish-American war. The two are therefore listed here together as "Spanish-American-Philippine" war.

The Correlates of War (COW) data include multiple US uses of military force during the Vietnam War era. It starts with "Vietnam Phase 1", 1961-65, with 506 battle deaths in the COW data base. It includes the "Second Laotian" war phases 1 and 2, plus engagement with a "Communist Coalition" and Khmer Rouge as well as actions in the Dominican Republic and Guatemala. The current data.frame includes only "Vietnam", referring primarily to COW's "Vietnam War, Phase 2", 1965-1973. The associated battle deaths include battle deaths from these other, lesser concurrent conflicts.

The COW data currently ends in 2007. However, the post-2000 conflicts in Afghanistan and Iraq averaged less than 1,000 battle deaths per year or roughly 3 battle deaths per year per million population. This is below the threshold of 10 battle deaths per year per million population. This in turn suggests that any impact of those conflicts on the US economy might be small and difficult to estimate.

battleDeaths

numeric: Numbers of battle deaths by year estimated by allocating to the different years the totals reported for each major war in proportion to the number of days officially in conflict each year. The totals were obtained (in August-September 2015) from The Correlates of War data for conflicts since 1816 and from Wikipedia for previous wars back to 1774, as noted above.

battleDeathsPMP

numeric: battle deaths per million population = 1000*battleDeaths/population.K.

Keynes

integer taking the value 1 between 1939 and 1979 and 0 otherwise, as suggested by the section entitled "The Keynesian Ascendancy 1939-1979" in the Wikipedia article on John Maynard Keynes.

Clearly, the more recent numbers should be more accurate.

fedReceipts, fedOutlays, fedSurplus

Receipts and Outlays of the US federal government in millions of current dollars.

For data beginning with 1901, these are from the US federal budget from The White House (2022). Earlier data are from series Y 335-337 in US Census Bureau (1975). As of 2022-02-22 the data from The White House included aggregations for 1789-1849 and 1850-1900, which matched the totals of Y 335-337 for those two sets of years. The numbers from 1901 to 1933 are the same in both sources.

We used The White House (2022) for the more recent numbers with one exception: Between 1976 and 1977 the fiscal year was changed from starting July 1 to October 1. July, August, and September, 1976, is called the "transitional quarter", and has been deleted from this dataset.

NOTES:

The numbers for 1843 are for only the first half of the year, January 1 through June 30. This explains why the numbers for 1843 are only roughly half of the corresponding values for 1844 and 1845.

Also, the numbers for 1791 are actually for 1789-1791. However, those numbers seem comparable to those for 1792 and 1793, so it is listed as only for one year rather than three.

fedDebt

US federal government debt in millions of current dollars per FiscalData (2022). This matches Y 338 in United States Census Bureau (1975) 1921-1939 but not earlier, and Y 338 ends with 1939. Between 1921 and 1939 these numbers are as of June 30. Between 1843 and 1920 they are as of July 1. The earlier numbers are as of January 1.

FiscalData (2022) includes debt for both January 1 (20 million) and July 1 (33 million) for 1843. For present purposes, we omit the January 1 number. This overstates the volatility of the national debt during that period, showing it rising from 14 million in 1842 (January 1) to 33 million in 1843 (July 1), being 18 not 12 months. The alternative would be to delete the 33 million, but that would understate the volatility of the debt during that period.

fedReceipts_pGDP, fedOutlays_pGDP, fedSurplus_pGDP, fedDebt_pGDP

numeric = fedReceipts, fedOutlays, fedSurplus, and fedDebt divided by (population.K * realGPDperCapita / (GDPdeflator)), except for the single year 1843, for which fedReceipts, fedOutlays, and fedSurplus were for only the first six months; to compute *_pGDP for these numbers for 1843 only, the denominator in this formula is cut in half to compensate.

US Postal Service

Description

Numbers of post offices in the US from 1789 to 2020 with their income and expenses in current dollars and proportion of the federal government and of Gross Domestic Product (GDP). Also includes the number of pieces of mail, numbers of periodicals, pieces and periodicals per person, and cost coverage of periodicals for selected years.

It would be interesting to find the total value of the subsidies for newspapers and other periodicals as a proportion of the budgets of the USPS and the federal government as well as of GDP. That is currently absent from the data consulted to produce this.

Usage

data(USPS)

Format

A data.frame containing 232 observations on the following variables:

Year

integer: the year: 1789:2020

Income, Expenses

Income and expenses in millions of current dollars, per Historian (2022).

Income_pFed, Expenses_pFed

Income and Expenses as a proportion of USGDPpresidents[, 'fedReceipts'] and USGDPpresidents[, 'fedOutlays'], respectively.

Income_pGDP, Expenses_pGDP

Income and Expenses as a proportion of GDP, per MeasuringWorth.

Income_cap, Expenses_cap

Income and Expenses per capita in current dollars = Income and Expenses divided by 1000 * USGDPpresidents[, 'population.K'].

realIncome_cap, realExpenses_cap

Income and Expenses per capita in constant 2012 dollars = Income_cap and Expenses_cap divided by USGDPpresidents[, 'GDPdeflator'].

postOffices

Number of post offices per Historian (2022).

KpopPerPostOffice

US population in thousands per post office: USGDPpresidents[, 'population.K'] divided by postOffices.

piecesOfMail, periodicals

numeric: Millions of pieces of mail handled and periodicals mailed. "Pieces of mail"" are from Historian (2022). "Periodicals" are from Historian (2010).

piecesOfMailPerCap, periodicalsPerCap

piecesOfMail and periodicals handled per capita (per human in the US) per year.

costCoveragePeriodicals

Cost coverage of periodicals, per Historian (2010). This is available here only since 1960, though Historian (2010) gave a general outline of these numbers. This included saying, "In 1966, the percentage of its own costs covered by second-class mail (or 'cost coverage'), including the subsidy, was 35 percent [reported as 36 percent here]. Its real coverage was 24 percent." The narrative noted that during parts of the nineteenth century the actual rate was zero. Sometimes it was zero only within county. Sometimes advertising was charged a higher rate than news.

Other than numbers for the period since 1960, we note the coverage in 1951 as 20 percent, based on the following comment:

"In February 1951, in a special message to Congress, President Harry S. Truman argued at length for a rate increase: 'In fiscal year 1952 . . . newspaper and magazine publishers will have 200 million dollars – or 80 percent – of their postal costs paid for them by the general public.'"

Details

rownames(USPS) = year

Data used by McChesney and Nichols (2021-12-13) To Protect and Extend Democracy, Recreate Local News Media (Freepress.net, p. 6, note 10) to estimate that newspaper subsidies averaged roughly 0.216 percent of GDP between 1840 and 1844.

Robert W. McChesney and John Nichols (2010) The Death and Life of American Journalism (Nation Books, pp. 310-311) describe how they computed 0.216 as an estimate of the percent of national income (Gross Domestic Product, GDP) devoted to newspaper subsidies, 1840-1844. The numbers in the current dataset seem essentially equivalent but new and therefore perhaps more accurate. With these numbers, we got 0.209 percent of GDP rather than their 0.216 percent.

Official Secrecy of the United States Government

Description

Data on classification activity of the United States government.

Fitzpatrick (2013) notes that the dramatic jump in derivative classification activity (DerivClassActivity) that occurred in 2009 coincided with "New guidance issued to include electronic environment". Apart from the jump in 2009, the DerivClassActivity tended to increase by roughly 12 percent per year (with a standard deviation of the increase in the natural logarithm of DerivClassActivity of 0.18).

Usage

data(USclassifiedDocuments)

Format

A dataframe containing :

year

the calendar year

OCAuthority

Number of people in the government designated as Original Classification Authorities for the indicated year.

OCActivity

Original classification activity for the indicated year: These are the number of documents created with an original classification, i.e., so designated by an official Original Classification Authority.

TenYearDeclass

Percent of OCActivity covered by the 10 year declassification rules.

DerivClassActivity

Derivative classification activity for the indicated year: These are the number of documents created that claim another document as the authority for classification.

Details

The lag 1 autocorrelation of the first difference of the logarithms of DerivClassActivity through 2008 is -0.52. However, because there are only 13 numbers (12 differences), this negative correlation is not statistically significant.

US incarcerations 1925 onward

Description

Counts of prisoners under the jurisdiction of state and federal correctional authorities in the US. This does not include jail inmates.

Usage

data("USincarcerations")

Format

A data frame with 95 observations on the following 7 variables.

year

an integer vector giving the year c(1925:2019).

stateFedIncarcerees

Total number of incarcerees = maleTotal + femaleTotal.

stateFedIncarcerationRate

incarceration rate = stateFedIncarcerees per 100,000 population.

stateFedMales

Total number of male incarcerees.

stateFedMaleRate

male incarceration rate = maleTotal per 100,000 males in the US population.

stateFedFemales

Total number of female incarcerees.

stateFedFemaleRate

female incarceration rate = femaleTotal per 100,000 females in the US population.

Details

This dataset began as an effort to update File:U.S. incarceration rates 1925 onwards.png on Wikimedia Commons. Conveniently data on these variables was provided in a table for 1925 to 2014. And a description was given of how to update that table using files p*t03.csv and p*t05.csv from Prisoners In 2019.

An initial rationality check was to compute

checkTot <- stateFedIncarcerees - stateFedMales - stateFedFemales

This was 0 except for 1927 and 1973, when it was 637 and 684. The stateFedFemales for 1972:1974 was 6269, 6004, 7389. We replaced 6004 with 6688, which made the checkTot 0 for 1973.

Similar checks for 1927 yielded nothing as obvious. However, the stateFedIncarcerees increased 6.9 percent in 1926 over 1925, and 12.2 and 5.8 percent in the following two years. Subtracting 637 from 109983 for 1927 gave us 109346, which reduced the increase to 11.6 percent for 1927. It's no longer the maximum annual increase prior to 1975.

Next, these numbers were compared with those in p19t03.csv and p19t05.csv, which include numbers of incarcerees and rates per 100,000 population for 2009:2019. The numbers were identical for 2009:2011, but there were several differences for the more recent counts.

For USincarcerations, we used the numbers from p19t03.csv and p19t05.csv, because they seem likely to be more accurate.

However, these numbers include only people in state and federal prisons. It excludes jails.

Key Statistic: Total correctional population includes a plot of "Total adult correctional population 1980-2016", which does include jails. The data there are available as Total_correctional_population_counts_by_status.csv. Data on these variables covering 2008-2018 are available as cpus1718.csv from "Data tables" at Publication Correctional Populations In The United States, 2017-2018. The data in cpus1718.csv is mostly but not entirely identical to "Total adult correctional population 1980-2016" for 2008-2016, the period of overlap. We therefore used the older data up to 2007 and cpus1718.csv for 2008-2018.

Actual analysis of the jail data is left for another project.

Number of Words in US Tax Law

Description

Thousands of words in US tax law for 1995 to 2015 in 10 year intervals. This includes income taxes and all taxes in the code itself (written by congress) and regulations (written by government administrators). For 2015 only EntireTaxCodeAndRegs is given; for other years, this number is broken down by income tax vs. other taxes and code vs. regulations.

Usage

data(UStaxWords)

Format

A data.frame containing:

year

tax year

IncomeTaxCode

number of words in thousands in the US income tax code

otherTaxCode

number of words in thousands in US tax code other than income tax

EntireTaxCode

number of words in thousands in the US tax code

IncomeTaxRegulations

number of words in thousands in US income tax regulations

otherTaxRegulations

number of words in thousands in US tax regulations other than income tax

IncomeTaxCodeAndRegs

number of words in thousands in both the code and regulations for the US income tax

otherTaxCodeAndRegs

number of words in thousands in both code and regulations for US taxes apart from income taxes.

EntireTaxCodeAndRegs

number of words in thousands in US tax code and regulations

Details

Thousands of words in the US tax code and federal tax regulations, 1955-2015. This is based on data from the Tax Foundation (taxfoundation.org), adjusted to eliminate an obvious questionable observation in otherTaxRegulations for 1965. The numbers of words in otherTaxRegulations was not reported directly by the Tax Foundation but is easily computed as the difference between their Income and Entire tax numbers. This series shows the numbers falling by 48 percent between 1965 and 1975 and by 1.5 percent between 1995 and 2005. These are the only declines seen in these numbers and seem inconsistent with the common concern (expressed e.g., in Moody, Warcholik and Hodge, 2005) about the difficulties of simplifying any governmental program, because vested interest appear to defend almost anything. Lessig (2011) notes that virtually all provisions of US law that favor certain segments of society are set to expire after a modest number of years. These sunset provisions provide recurring opportunities for incumbent politicians to extort campaign contributions from those same segments to ensure the continuation of the favorable treatment.

The decline of 48 percent in otherTaxRegulations seems more curious for two additional reasons: First, it was preceded by a tripling of otherTaxRegulations between 1955 and 1965. Second, it was NOT accompanied by any comparable behavior of otherTaxCode. Instead, the latter grew each decade by between 17 and 53 percent, similar to but slower than the growth in IncomeTaxCode and IncomeTaxRegulations.

Accordingly, otherTaxRegulations for 1965 is replaced by the average of the numbers for 1955 and 1975, and EntireTaxRegulations for 1965 is comparably adjusted. This replaces (1322, 2960) for those two variables for 1965 with (565, 2203). In addition, otherTaxCodeAndRegs and EntireTaxCodeAndRegulations are also changed from (1626, 3507) to (870, 2751).

Independent of whether this adjustment is correct or not, it's clear that there have been roughly 3 words of regulations for each word in the tax code. Most of these are income tax regulations, which have recently contained 4.5 words for every word in code. The income tax code currently includes roughly 50 percent more words than other tax code.

Countries in Banking Crises

Description

A data.frame identifying which of 70 countries had a banking crisis each year 1800:2010. The first column is year. The remaining columns carry the names of the countries; those columns are 1 for years with banking crises and 0 otherwise.

Usage

data(bankingCrises)

Format

A data.frame

Details

This file was created using the following command:

bankingCrises <- readFinancialCrisisFiles(FinancialCrisisFiles)

HOWEVER: This function was in Ecfun 0.2-3 but was removed in 0.2-4. It used gdata::read.xls, and gdata users were informed that gdata might be removed from CRAN, and any package that used it would also be removed. It seemed that the database that this function was designed to read may not have been updated, which suggested that it made sense to remove this function, because it there may not be any further need for it.

This dataset is an update of a subset of the data used to create Figure 10.1. Capital Mobility and the Incidence of Banking Crises, All Countries, 1800-2008, Reinhart and Rogoff (2009, p. 156).

The general upward trend visible in a plot of these data may be attributed to at least two different factors:

(1) The gradual increase in the proportion of human labor that is monetized.

(2) An increase in the general ability of cronies of those in power to gamble with other people's money in forming and bankrupting financial institutions. The marked feature of this plot is the virtual absence of banking crises during the period of the Bretton Woods agreement, 1944 to 1971. This period ended when US President Nixon in effect canceled the Bretton Woods agreement by taking the US off the silver standard.

Cyber Security Breaches

Description

data.frame of cyber security breaches involving health care records of 500 or more humans reported to the U.S. Department of Health and Human Services (HHS) as of June 27, 2014.

Usage

data(breaches)

Format

A data.frame with 1055 observations on the following 24 variables:

Number

integer record number in the HHS data base

Name_of_Covered_Entity

factor giving the name of the entity experiencing the breach

State

Factor giving the 2-letter code of the state where the breach occurred. This has 52 levels for the 50 states plus the District of Columbia (DC) and Puerto Rico (PR).

Business_Associate_Involved

Factor giving the name of a subcontractor (or blank) associated with the breach.

Individuals_Affected

integer number of humans whose records were compromised in the breach. This is 500 or greater; U.S. law requires reports of breaches involving 500 or more records but not of breaches involving fewer.

Date_of_Breach

character vector giving the date or date range of the breach. Recodes as Dates in breach_start and breach_end.

Type_of_Breach

factor with 29 levels giving the type of breach (e.g., "Theft" vs. "Unauthorized Access/Disclosure", etc.)

Location_of_Breached_Information

factor with 41 levels coding the location from which the breach occurred (e.g., "Paper", "Laptop", etc.)

Date_Posted_or_Updated

Date the information was posted to the HHS data base or last updated.

Summary

character vector of a summary of the incident.

breach_start

Date of the start of the incident = first date given in Date_of_Breach above.

breach_end Date of the end of the incident or NA if only one date is given in Date_of_Breach above. year integer giving the year of the breach

Details

The data primarily consists of breaches that occurred from 2010 through early 2014 when the extract was taken. However, a few breaches are recorded including 1 from 1997, 8 from 2002-2007, 13 from 2008 and 56 from 2009. The numbers of breaches from 2010 - 2014 are 211, 229, 227, 254 and 56, respectively. (A chi-square test for equality of the counts from 2010 through 2013 is 4.11, which with 3 degrees of freedom has a significance probability of 0.25. Thus, even though the lowest number is the first and the largest count is the last, the apparent trend is not statistically significant under the usual assumption of independent Poisson trials.)

Global cooling from a nuclear war

Description

Average surface temperature changes world wide and in the Northern Hemisphere 3 and 10 years after the injections of 5, 50 and 150 Tg (teragrams = millions of metric tons) of smoke into the upper troposphere, per Robock, Oman, and Stenchikov (2007).

These numbers are relative to the average for 1925-1975, which explains why the numbers are positive with smoke = 0.

Usage

data(coolingFromNuclearWar)

Format

A dataframe containing :

smoke

teragrams = millions of metric tons

dC3g, dC10g, dC3n, dC10n

average change in surface temperature 3 and 10 years after injection of smoke into the upper troposphere globally (g) or in the Northern Hemisphere (n) in degrees Celsius.

Income Inequality in the US

Description

Data on quantiles of the distributions of family incomes in the United States. This combines three data sources:

(1) US Census Table F-1 for the central quantiles

(2) Piketty and Saez for the 95th and higher quantiles

(3) Gross Domestic Product and implicit price deflators from Measuring Worth. (NOTE: The Measuring Worth Web site, https://MeasuringWorth.com, often gives security warnings. The desired data still seems to be available and not corrupted, however.)

Usage

data(incomeInequality)

Format

A data.frame containing:

Year

numeric year 1947:2012

Number.thousands

number of families in the US

quintile1, quintile2, median, quintile3, quintile4, p95

quintile1, quintile2, quintile3, quintile4, and p95 are the indicated quantiles of the distribution of family income from US Census Table F-1. The media is computed as the geometric mean of quintile2 and quintile3. This is accurate to the extent that the lognormal distribution adequately approximates the central 20 percent of the income distribution, which it should for most practical purposes.

P90, P95, P99, P99.5, P99.9, P99.99

The indicated quantiles of family income per Piketty and Saez

realGDP.M, GDP.Deflator, PopulationK, realGDPperCap

real GDP in millions, GDP implicit price deflators, US population in thousands, and real GDP per capita, according to MeasuringWorth.com. (NOTE: The web address for this, https://MeasuringWorth.com, seems to be functional but may not be maintained to current internet security standards. It is therefore given here as text rather than a hot link.)

P95IRSvsCensus

ratio of the estimates of the 95th percentile of distributions of family income from the Piketty and Saez analysis of data from the Internal Revenue Service (IRS) and from the US Census Bureau.

The IRS has ranged between 72 and 98 percent of the Census Bureau figures for the 95th percentile of the distribution, with this ratio averaging around 75 percent since the late 1980s. However, this systematic bias is modest relative to the differences between the different quantiles of interest in this combined dataset.

personsPerFamily

average number of persons per family using the number of families from US Census Table F-1 and the population from MeasuringWorth. (Note: The web site for Measuring Worth, https://MeasuringWorth.com, often gives security warnings. It still seems to work. It seems that the web site is not maintained to current internet security standards.)

realGDPperFamily

personsPerFamily * realGDPperCap

mean.median

ratio of realGDPperFamily to the median. This is a measure of skewness and income inequality.

Details

For details on how this data.frame was created, see "F1.PikettySaez.R" in system.file('scripts', package='fda'). This provides links for files to download and R commands to read those files and convert them into an updated version of incomeInequality. This is a reasonable thing to do if it is more than 2 years since max(incomeInequality$year). All data are in constant 2012 dollars.

Global Terrorism Database yearly summaries

Description

The Global Terrorism Database (GTD) "is a database of incidents of terrorism from 1970 onward". Through 2020, this database contains information on 209,706 incidents.

terrorism provides a few summary statistics along with an ordered factor methodology, which Pape et al. insisted is necessary, because an increase of over 70 percent in suicide terrorism between 2007 and 2013 is best explained by a methodology change in GTD that occurred on 2011-11-01; Pape's own Suicide Attack Database showed a 19 percent decrease over the same period.

Usage

  data(terrorism)
  data(incidents.byCountryYr)
  data(nkill.byCountryYr)

Format

incidents.byCountryYr and nkill.byCountryYr are matrices giving the numbers of incidents and numbers of deaths by year and by location of the event for 204 countries (rows) and for all years between 1970 and 2060 (columns) except for 1993, for which the entries are all NA, because the raw data previously collected was lost (though the total for that year is available in the data.frame terrorism).

NOTES:

1. For nkill.byCountryYr and for terrorism[c('nkill', 'nkill.us')], NAs in GTD were treated as 0. Thus the actual number of deaths were likely higher, unless this was more than offset by incidents being classified as terrorism, when they should not have been.

2. incidents.byCountryYr and nkill.byCountryYr are NA for 1993, because the GTD data for that year were lost.

terrorism is a data.frame containing the following:

year

integer year, 1970:2020.

methodology

an ordered factor giving the methodology / organization responsible for the data collection for most of the given year. The Pinkerton Global Intelligence Service (PGIS) managed data collection from 1970-01-01 to 1997-12-31. The Center for Terrorism and Intelligence Studies (CETIS) managed the project from 1998-01-01 to 2008-03-31. The Institute for the Study of Violent Groups (ISVG) carried the project from 2008-04-01 to 2011-10-31. The National Consortium for the Study of Terrorism and Responses to Terrorism (START) has managed data collection since 2011-11-01. For this variable, partial years are ignored, so methodology = CEDIS for 1998:2007, ISVG for 2008:2011, and START for more recent data.

method

a character vector consisting of the first character of the levels of methodology:

c('p', 'c', 'i', 's')

incidents

integer number of incidents identified each year.

NOTE: sum(terrorism[["incidents"]]) = 214660 = 209706 in the GTD database plus 4954 for 1993, for which the incident-level data were lost.

incidents.us

integer number of incidents identified each year with country_txt = "United States".

suicide

integer number of incidents classified as "suicide" by GTD variable suicide = 1. For 2007, this is 359, the number reported by Pape et al. For 2013, it is 624, which is 5 more than the 619 mentioned by Pape et al. Without checking with the SMART project administrators, one might suspect that 5 more suicide incidents from 2013 were found after the data Pape et al. analyzed but before the data used for this analysis.

suicide.us

Number of suicide incidents by year with country_txt = "United States".

nkill

number of confirmed fatalities for incidents in the given year, including attackers = sum(nkill, na.rm=TRUE) in the GTD incident data.

NOTE: nkill in the GTD incident data includes both perpetrators and victims when both are available. It includes one when only one is available and is NA when neither is available. However, in most cases, we might expect that the more spectacular and lethal incidents would likely be more accurately reported. To the extent that this is true, it means that when numbers are missing, they are usually zero or small. This further suggests that the summary numbers recorded here probably represent a slight but not substantive undercount.

nkill.us

number of U.S. citizens who died as a result of incidents for that year = sum(nkill.us, na.rm=TRUE) in the GTD incident data.

NOTES:

1. This is subject to the same likely modest undercount discussed with nkill.)

2. These are U.S. citizens killed regardless of location. This explains at least part of the discrepancies between terrorism[, 'nkill.us'] and nkill.byCountryYr['United States', ].

nwound

number of people wounded. (This is subject to the same likely modest undercount discussed with nkill.)

nwound.us

Number of U.S. citizens wounded in terrorist incidents for that year = sum(nwound.us, na.rm=TRUE) in the GTD incident data. (This is subject to the same likely modest undercount discussed with nkill.)

pNA.nkill, pNA.nkill.us, pNA.nwound, pNA.nwound.us

proportion of observations by year with missing values. These numbers are higher for the early data than more recent numbers. This is particularly true for nkill.us and nwound.us, which exceed 90 percent for most of the period with methodology = PGIS, prior to 1998.

worldPopulation, USpopulation

Estimated de facto population in thousands living in the world and in the US as of 1 July of the year indicated, according to the Population Division of the Department of Economic and Social Affairs of the United Nations; see "Sources" below.

worldDeathRate, USdeathRate

Crude death rate (deaths per 1,000 population) worldwide and in the US, according to the World Bank; see "Sources" below. This World Bank data set includes USdeathRate for each year from 1900 to 2020.

NOTE: USdeathRate to 2009 is to two significant digits only. Other death rates carry more significant digits.

worldDeaths, USdeaths

number of deaths by year in the world and US

worldDeaths = worldPopulation * worldDeathRate.

USdeaths were computed by summing across age groups in "Deaths_5x1.txt" for the United States, downloaded from https://www.mortality.org/Country/Country?cntr=USA from the Human Mortality Database; see sources below.

kill.pmp, kill.pmp.us

terrorism deaths per million population worldwide and in the US =

nkill / (0.001*worldPopulation)

nkill.us / (0.001*USpopulation)

pkill, pkill.us

terrorism deaths as a proportion of total deaths worldwide and in the US

pkill = nkill / worldDeaths

pkill.us = nkill.us / USdeaths

Details

As noted with the "description" above, Pape et al. noted that the GTD reported an increase in suicide terrorism of over 70 percent between 2007 and 2013, while their Suicide Attack Database showed a 19 percent decrease over the same period. Pape et al. insisted that the most likely explanation for this difference is the change in the organization responsible for managing that data collection from ISVG to START.

If the issue is restricted to how incidents are classified as "suicide terrorism", this concern does not affect the other variables in this summary.

However, if it also impacts what incidents are classified as "terrorism", it suggests larger problems.
