The U.S. government is the dominant player in the global arms market. Existing literature emphasizes the many benefits of an international U.S. government arms monopoly including: regional and global balance, stability and security, the advancement of U.S. national interests, and domestic economic benefits from international sales. The purpose of this paper is to balance this largely one-sided treatment of the U.S. government’s dominant position in the international arms market. We discuss several negative consequences and costs associated with U.S. arms sales which call into question the net benefit of the U.S. government’s control over global arms.  相似文献

Summary This paper generalizes a result by Stadje (1984) by deriving conditions for which a general dependency structure for multivariate observations, given in Pavur (1987), yields a positive definite covariance structure. This general dependency structure allows the sample covariance matrix to be distributed as a constant times a Wishart random matrix. It is then demonstrated that the maximum squared-radii test and a test for equal population covariance matrices have null distributions which remain unchanged when the new general dependency structure, rather than the usual independence structure, for the vector observations, is assumed. Moreover, under a general dependency structure for which the population covariance matrices are unequal, it is shown that the distribution of the test statistic for testing equal covariance matrices is identical to the distribution of the same test statistic when the population covariance matrices are equal and the observations are independent.  相似文献

This study uses responses from a survey of marketing professionals in a structural equation model linking antecedents and consequences of two dimensions of personal moral philosophies (idealism and relativism) and perceived moral intensity (PMI). Mixed support is found for hypothesized effects of gender, religiosity, education, experience, salary, and corporate ethical values on idealism and relativism. Idealism increases and relativism decreases PMI in four ethical scenarios. PMI increases perceptions of ethical problems, which reduce intentions to act unethically. The study tests whether relationships between variables, revealing that PMI has direct as well as indirect effects on intentions. Intentions are also influenced by gender: women have more ethical intentions than men, on average, and this effect is not mediated by other variables in the model.

Simpler Probabilistic Population Forecasts: Making Scenarios Work   总被引:1,自引:0,他引:1  
The traditional high-low-medium scenario approach to quantifying uncertainty in population forecasts has been criticized as lacking probabilistic meaning and consistency. This paper shows, under certain assumptions, how appropriately calibrated scenarios can be used to approximate the uncertainty intervals on future population size and age structure obtained with fully stochastic forecasts. As many forecasting organizations already produce scenarios and because dealing with them is familiar territory, the methods presented here offer an attractive intermediate position between probabilistically inconsistent scenario analysis and fully stochastic forecasts.  相似文献

We examine the effect of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) on the quality of household food purchases using the National Household Food Acquisition and Purchase Survey (FoodAPS) and propensity score matching. A healthy purchasing index (HPI) is used to measure nutritional quality of household food purchases. WIC foods explain the improvement in quality of food purchases, not self‐selection of more nutrition‐conscious households into the program. The improvement in purchase quality was driven entirely by WIC participating households who redeemed WIC foods during the interview week. There was no significant difference between WIC participants who did not redeem WIC foods and eligible nonparticipants. In this sample, there is no evidence that lack of access to clinics has adverse effects on participation nor is there evidence that HPI depends on supermarket access. A supervised machine learning process supports our main conclusion on the importance of WIC foods.  相似文献

We analyze the pay and position of 1009 faculty members who teach in doctoral‐granting economics departments at 53 large public universities in the United States. Using the Web of Science, we have identified the journal articles published by these scholars and the number of times each of these articles has been subsequently cited in published research articles. We find that research influence, as measured by various measures of total citations, is a remarkably strong predictor of the salary and the prestige of the department in which professors are employed. We also examine the effect of coauthorship. Surprisingly, we find no salary penalty for sharing authorship; however, in terms of prestige of employing department, coauthorship is fully discounted.  相似文献

A major gap in our understanding of the medieval economy concerns interest rates, especially relating to commercial credit. Although direct evidence about interest rates is scattered and anecdotal, there is much more surviving information about exchange rates. Since both contemporaries and historians have suggested that exchange and rechange transactions could be used to disguise the charging of interest in order to circumvent the usury prohibition, it should be possible to back out implied interest rates from exchange rates. The analysis presented in this article is based on a new dataset of medieval exchange rates collected from commercial correspondence in the archive of Francesco di Marco Datini of Prato, c. 1383–1411. It demonstrates that the time value of money was consistently incorporated into market exchange rates. Moreover, these implicit interest rates are broadly comparable to those received from other types of commercial loan and investment. Although on average profitable, the return on any individual exchange and rechange transaction did involve a degree of uncertainty that may have justified their non‐usurious nature. However, there were also practical reasons why medieval merchants may have used foreign exchange transactions as a means of extending credit.  相似文献

While substantial revisions to auditor reporting requirements are being implemented internationally, the impact of these reforms on financial reporting quality is unknown. We exploit the United Kingdom's recent auditor reporting changes and find that the United Kingdom's new reporting regime is associated with an improvement in financial reporting quality as proxied by significant decreases in absolute abnormal accruals and the propensity to just meet or beat analyst forecasts, and a significant increase in earnings response coefficients. As for audit costs, we do not find a significant change in audit fees or audit delay surrounding the implementation of the new reporting regime. Taken together, the results of this study suggest that new auditor reporting requirements are associated with a significant improvement in financial reporting quality without detecting a significant increase in audit costs.  相似文献

Ecosystem service provision in agriculture may require cooperation between farmers. Trust fosters cooperation in many economic and social interactions and is important to the success of traditional agricultural cooperatives. Little is known about how trust affects farmers’ willingness to cooperate to provide an ecosystem service, what types of trust are most important, and under what conditions trust may matter. In this study, we present results of a survey of Missouri crop farmers exploring the role trust plays in farmers’ stated willingness to cooperate to control pests. We find that most farmers say they are willing to cooperate, and most farmers are willing to trust others. However, we find little evidence that trust positively influences farmers’ willingness to cooperate to control pests. Instead, we find that trust may only matter under certain conditions, such as when participants’ farms are dissimilar, and that other determinants, such as the perceived benefit of cooperation and environmental concern, are more important than trust to farmers who are contemplating cooperation to control pests.  相似文献
