Despite financial innovations that have created important new substitutes for cash usage, per capita holdings of U.S. currency
amount to $2950. Yet American households and businesses admit to holding only 15% of the currency stock, leaving the whereabouts
of 85% unknown. Some fraction of this unaccounted for currency is held abroad (the dollarization hypothesis) and some is held
domestically undeclared, as a store of value and a medium of exchange for transactions involving the production and distribution
of illegal goods and services, and for transactions earning income that is not reported to the IRS (the unreported economy
hypothesis). We find that the percentage of U.S. currency currently held overseas is between 30 and 37% rather than the widely
cited figure of 65%. This finding is based on the official Federal Reserve/Bureau of Economic Analysis data which is a proxy
measure of the New York Federal Reserve’s (NYB) “confidential” data on wholesale currency shipments abroad. We recommend that
the NYB data be aggregated so as to circumvent confidentiality concerns, and be made readily available to all researchers
in order to shed greater light on the questions of how much U.S. currency is abroad and on the particular location of overseas
U.S. dollars. The newly revised official estimates of overseas currency holdings are employed to determine the Federal Reserve’s
seigniorage earnings from 1964–2010, which have provided a $2950. Yet American households and businesses admit to holding only 15% of the currency stock, leaving the whereabouts
of 85% unknown. Some fraction of this unaccounted for currency is held abroad (the dollarization hypothesis) and some is held
domestically undeclared, as a store of value and a medium of exchange for transactions involving the production and distribution
of illegal goods and services, and for transactions earning income that is not reported to the IRS (the unreported economy

U.S. dollars. The newly revised official estimates of overseas currency holdings are employed to determine the Federal Reserve’s
seigniorage earnings from 1964–2010, which have provided a 287 billion windfall for U.S. taxpayers. Overseas currency stock
data are also used to derive estimates of the domestically held stock of currency as well as narrow and broad measures of domestic monetary aggregates. These domestic monetary aggregates are believed to be better predictors of future economic activity than traditional monetary aggregates
and are tested to determine their ability to predict fluctuations in real output and prices. Domestic cash holdings are finally
used to estimate the size of the U.S. unreported economy as measured by the amount of income that is not properly reported
to the IRS. By 2010, we estimate that legal and illegal source unreported income” is $1.9–$1.9–2.4 trillion, implying a “tax gap”
in the range of $400–$400–540 billion. Currently, we estimate that 18–23% of total reportable income is not properly reported
to the IRS. 相似文献

Based on ethnographic data, this essay analyzes the social order properties of a poor urban street, in a small city in the
northeast United States, on which drug dealing is the principle occupation. Rather than treating drug dealing as an agent
of disorder, we focus on the order properties of drug dealing and the ordered character of the local code of conduct that
develops around it. Like Sudhir Venkatesh (American Journal of Sociology 103:82–111, 1997) we examine the interface between drug dealing and the neighborhood. However, in this small urban space the drug dealers
are not outsiders, rather, they are long term residents: established insiders who are well integrated into community life.
As such their work practices and the requirements they place on behavior in public spaces impact the neighborhood in comprehensive
ways. We detail the phenomenon Elijah Anderson called the “code of the street” (Anderson 1999) as a set of practices and social markers, a local Interaction Order (Goffman, American Sociological Review 48:1–17, 1983; Rawls, Sociological Theory 2:136–149, 1987), that furnishes basic day to day sensemaking tools for residents (Rawls 2009). We propose that this order has a constitutive character that furnishes stable expectations (Garfinkel 1963, 1967) for meaningful social action and identity in the neighborhood. In a context of industrial decline and urban poverty, drug
dealing careers constitute a major socialization factor, that touches everyone here—especially children. 相似文献

This study investigates the factors that shape the attitudes of scientists toward starting their own business or working in
a private sector firm. The analysis is based on data collected from scientists working in the German Max Planck Society, a
research institution devoted to basic science. We find that the scientists’ attractiveness of working in a private sector
firm or of starting their own business differ considerably according to their academic discipline and the self-reported commercial
potential of their research. The ability to take risks, prior work experience in private firms, and personal experience in
cooperating with industry lead to a positive attitude towards switching to private sector employment or entrepreneurship.
Strong willingness to freely distribute research findings is related to a low appeal of private sector work. 相似文献

The fallibility of forensic science consultation is an ongoing and major justice concern. Prospective peer‐reviewed forensic consultation has over 10 years of application in American criminal and civil courts, adapting from the traditional oversight of teaching hospitals, rules of evidence and discovery, conventions of testimony of expert witnesses, and attorneys' overall trial strategy. In systematizing heightened oversight, this process ensures greater accountability in forensic science consultation. The integration of peer reviewers' complementary expertise and experience enhances the sophistication and overall quality of assessment. Forensic examination frequently involves the interface of different specialties. Multidisciplinary peer review augments expert proficiency with that of professional peers having different vantage points from relevant scientific disciplines. This approach ensures greater sophistication of a case inquiry, built‐in accountability, and streamlined processes when multiple experts are necessitated. Here, the authors present examples of several cases and the primary and secondary benefits of this collaborative, rigorous, cross‐disciplinary exercise. 相似文献

The European Union (EU) has firmly set its stall out to protect individuals' data and privacy and has demonstrated this through the rejection of the old opt-out regime and the introduction of the new opt-in rules. These require businesses to obtain individual's prior and informed consent before their data are collected, stored and used for the purposes of online behavioural advertising (OBA). Individuals in the EU are afforded protection from the apparent dangers relating to data privacy and misuse that is associated with OBA, which is beyond the expectation of most Internet users. However, there are some criticisms levelled at the law that the EU has produced. Is simply gaining informed consent sufficient for protecting all types of information? Do certain types of information require a higher level of consent than others? Does the law fulfil its aim of protecting data subject's privacy and data? Is the current law restrictive to business? Do individuals know or care that their information is being collected for the purposes of targeted advertising and is there a better way to ensure that they do? Finally, will proposed new law to be found in the EU Data Protection Regulation solve any of these problems? This article will assess whether, as a policy decision, the EU's current approach has been too cautious in its attempts to protect individuals or restrict business. 相似文献

Few Indian reservations have any semblance of a private sector. Consequently, poverty and unemployment are major problems in much of Indian country. While there are many reasons why private enterprise is scarce in Indian country, one of the foremost reasons is businesses do not trust tribal courts. Businesses' distrust of tribal courts is not unique as outsiders often fear bias in foreign tribunals. Similarly, businesses are often concerned about a court's capacity to adjudicate complex disputes. Federal diversity jurisdiction was developed to allay fear of bias, and many states have developed business courts to address questions about court capacity. Tribes can overcome these issues by creating an intertribal business court (IBC). Tribes will be free to sculpt the IBC as they see fit. However, the IBC's intertribal nature will help reduce fears of bias, and an IBC's focus on business disputes will answer doubts about court capacity. An IBC will also make tribal law more accessible, further increasing confidence in this new tribunal. As businesses gain greater confidence in tribal legal institutions through the IBC, they will be more likely to operate in Indian country. Accordingly, the IBC could help to transform tribal economies. 相似文献

We distinguish between (i) voting systems in which voters can rank candidates and (ii) those in which they can grade candidates, using two or more grades. In approval voting, voters can assign two grades only—approve (1) or not approve (0)—to candidates. While two grades rule out a discrepancy between the average-grade winners, who receive the highest average grade, and the superior-grade winners, who receive more superior grades in pairwise comparisons (akin to Condorcet winners), more than two grades allow it. We call this discrepancy between the two kinds of winners the paradox of grading systems, which we illustrate with several examples and whose probability we estimate for sincere and strategic voters through a Monte Carlo simulation. We discuss the tradeoff between (i) allowing more than two grades, but risking the paradox, and (ii) precluding the paradox, but restricting voters to two grades. 相似文献
