Classic theories of comparative advantage point to factor productivity and factor abundance as determinants of specialization and trade. Likewise, geography and topography can determine trade patterns. Institutions, however, are increasingly seen as important sources of comparative advantage. A global drug prohibition regime implies that institutional quality matters more than traditional sources in the drug trade. This paper theoretically models trade patterns of illicit goods and confirms the role of institutions empirically with respect to the drug trade. In particular, illicit enterprises gain force in countries where resources are scarce, drug enforcement is uncertain, and institutions are weak in absolute terms and relative to neighboring countries. I propose several policy alternatives that emphasize economic opportunity for the poor and institutional quality that complement drug prohibition. 相似文献

In this paper we assess overall accuracy in survey self-reports on giving to charitable organizations, direction of bias in
self-reports, and the influence of this bias on relationships. We compare donations to one specific health charity reported
in the Giving in the Netherlands Panel Study 2003 with donations recorded in the database (n = 191). We find that (a) reported donations are significantly higher than recorded donations; (b) reported amounts contributed
are correlated very strongly with recorded contributions; (c) differences between amounts reported and amounts recorded are
positively related to education, religious affiliation, and the tendency to social desirability, and negatively to household
income. This suggests that effects of education are overestimated and effects of income and religious affiliation are underestimated
using self-reports on donations rather than archival records. 相似文献

选择FGT贫困指数和脱贫时间指数,利用世界银行公布的我国农村贫困线和收入分配分组数据。对比分析了1981年-2005年以来的农村贫困变化趋势。研究发现,农村贫困状况虽然总体上呈缓解趋势,但在脱贫时间指数的构成中,由于不平等所延长的脱贫时间,无论从绝对量还是相对量上都明显提高,这说明收入分配的恶化已经成为反贫困的严重障碍,这种变化趋势值得高度关注。 相似文献

Mixed methods researchers often neglect the methodological discussion on data in general and process-generated data specifically.
Assuming that the advantages and disadvantages of surveys, interviews and observations are well-known, the author discusses
when and why researchers should prefer process-generated data to research-elicited data in market sociology. The author then
compares four different types of process-generated data (aggregated statistical data, business directories, newspaper articles,
engineering literature). For each data type, the author (a) describes the data type, (b) illustrates what kind of information
researchers can gain from this data type and (c) discusses the draw-backs and limits of the data. The article concludes with
a discussion of what one can learn for mixing methods and market sociology from this example and why primary data might be
useful as an alternative data source after all. 相似文献

Bond laddering is a popular fixed-income investment strategy. The main purpose of this paper is to develop a methodology for determining private investors’ most interest rate risk (IRR)-return-efficient investment horizon for bond ladders (BLs), which are virtually free of credit risk. Two IRR measures of a continuously rolling and homogenous BL (CRHBL) are analytically derived under the assumption that interest rates are martingales. The first measure is the modified duration, which assumes a flat term structure of interest rates. However, this assumption is not fully supported by the empirical data and, thus, an additional IRR measure is proposed. Under each of these two measures, the ratios between the annual return in excess of the demand deposit rate and IRR of CRHBLs with different investment horizons are calculated. As expected, CRHBLs with rather low IRR are most risk-return-efficient. The results for the theoretical CRHBLs also apply to “real-world” discrete BLs. Thus, the proposed methodology can help private investors construct IRR-return-efficient discrete BLs. 相似文献

Are directors’ dealings reports informative for outside investors? We analyze short-term announcement effects for 2782 companies from eight European countries between January 2003 and December 2009. We find significant announcement effects in four out of eight countries after directors’ dealings reports have been disclosed. For most countries, the magnitude of the announcement effect depends on transaction size, firm size, book-to-market ratio, and multiple trades by different insiders on the same trading day. The results are stronger for purchases than for sales. For France, Ireland, and Sweden, we find tentative evidence that the corporate position of an insider is connected to the size of the announcement effect. 相似文献
