Research on the political economy of immigration overlooks the specificity of human capital in skilled occupations and its implications for immigration preferences and policymaking. Conclusions that skilled Americans are unconcerned about labor market competition from skilled migrants build on a simple dichotomy between high and low skill migrants. In this article we show that natives turn to occupational licensing regulations as occupation-specific protectionist barriers to skilled migrant labor competition. In practice, high skill natives face labor market competition only from those high-skill migrants who share their occupation-specific skills. Licensure regulations ostensibly serve the public interest by certifying competence, but they can simultaneously be formidable barriers to entry by skilled migrants. From a collective action perspective, skilled natives can more easily secure sub-national, occupation-specific policies than influence national immigration policy. We exploit the unique structure of the American medical profession that allows us to distinguish between public interest and protectionist motives for migrant physician licensure regulations. We show that over the 1973–2010 period states with greater physician control over licensure requirements imposed more stringent requirements for migrant physician licensure and, as a consequence, received fewer new migrant physicians. By our estimates over a third of all US states could reduce their physician shortages by at least 10 percent within 5 years just by equalizing migrant and native licensure requirements. This article advances research on the political economy of immigration and highlights an overlooked dimension of international economic integration: regulatory rent-seeking as a barrier to the cross-national mobility of human capital, and the public policy implications of such barriers. 相似文献

We were presented with the STR (short tandem repeat) profiles from two separate paternity trios. Each trio consisted of a mother, an alleged father, and products of conception (POC) that contained a hydatidiform mole but no visible fetus. In both cases , antecedent pregnancies had followed alleged sexual assaults. Mole classification and pathogenesis are described in order to explain the analyses and statistical reasoning used in each case. One mole exhibited several loci with two different paternal alleles, indicating it was a dispermic (heterozygous) mole. Maternal decidua contaminated the POC, preventing the identification of paternal obligate alleles (POAs) at some loci. The other mole exhibited only one paternal allele/locus at all loci and no maternal alleles, indicating it was a diandric and diploid (homozygous) mole. In each case, traditional calculations were used to determine paternity indices (PIs) at loci that exhibited one paternal allele/locus. PIs at mole loci with two different paternal alleles/locus were calculated from formulas first used for child chimeras that are always dispermic. Combined paternity indices in both mole cases strongly supported the paternity of each suspect. 相似文献

Studies find that members of preferential trade agreements (PTAs) are less likely to be involved in militarized conflict. An expectation of continuing amicable trade relations is among the factors linking PTAs to peace. However, this role of PTAs is difficult to test due to the problem of observational equivalence; PTAs correlate with trade levels and liberalization, factors also linked to peace. In this article, we isolate the impact of PTAs on trade expectations by distinguishing between signed agreements and those in force. A focus on signed but not-yet-in-force PTAs allows us to assess the correlation between agreements and peace before other pacifying, and therefore potentially confounding, elements emerge. Statistical tests spanning 1957 to 2000 demonstrate that signed PTAs are pacifying, while in-force agreements have no statistically significant impact when controlling for other factors linked to peace. 相似文献

A new phenomenon, moral exporting (ME), is introduced to capture active attempts to promote certain views of morality to others. It was hypothesized that political conservatives would be more likely to exhibit ME, due in part to strong epistemic concerns for certainty that may become attached to the moral domain. Related items from the 1988 and 2006 General Social Surveys were analyzed, and new scales were developed to better assess ME and specific moral-related epistemic concerns (moral absolutism). In a second study, these scales were administered to a large college student sample along with measures of political ideology and need for closure (NFC). Results generally showed that political conservatism was strongly related to the new ME factor. Further analysis determined that both moral absolutism (MA) and NFC accounted for significant portions of this relationship, but that the specific epistemic construct (MA) was a more proximal mediator. Discussion centers on further distinguishing ME and MA from related constructs, as well as on future research and applications. 相似文献

Facilities operated by public and nonprofit agencies have become increasingly important sources of primary care for Medicaid patients. These facilities are particularly important sources of care in segregated, competitive urban areas, where they are more geographically accessible than many private physicians and expand the availability of care to Medicaid patients rather than substituting for care provided by private physicians. In rural areas, in contrast, the availability of care from public facilities appears to reduce the level of care Medicaid patients receive from private physicians in the counties where these facilities are located. These findings suggest that policymakers can expand urban Medicaid patients' access to care by spending on public care, but at the cost of increasing the segregation of Medicaid patients into a two-tier system of care. 相似文献
