Despite debate regarding the magnitude of the impact, immigrant inflows are generally understood to depress wages and increase employment in immigrant-intensive sectors. In light of the overrepresentation of the foreign-born in the childcare industry, this article examines whether college-educated native women respond to immigrant-induced lower cost and potentially more convenient childcare opt...

Although evolutionary change within most species is thought to occur slowly, recent studies have identified cases where evolutionary change has apparently occurred over a few generations. Anthropogenically altered environments appear particularly open to rapid evolutionary change over comparatively short time scales. Here, we consider a Pacific salmon population that may have experienced life-h...

The paper explores migrant workers careers in the health sector, comparing the Spanish case and the British case. International migration has become an important feature of globalized labour markets in health care. Recently, concerns over the need of ensuring staff and skill shortages in the health system are becoming a common issue in many European countries. Following this, the paper is focus...

Migration as a human phenomenon has some consequences and repercussions. One of these effects is crime commitment and inducing disturbance in land and national security in immigrants' residence country, in other word, international migration, especially illegal migration, have different penal-security effects. Finding reason that the permeability of borders and increasing illegal traffic, drug ...

Why is there such wide-spread opposition to immigration, although attitudes are generally favorable towards trade? Using concepts from population ethics, this paper shows that impartial observers oppose unskilled immigration if they are inequality-averse, base their decisions on national interest, and have an integrative view of immigration. Moreover, unskilled immigration makes redistribution ...

New tools of genomic analysis shed light on historical puzzles. Migrations of ancient peoples, differences in migration patterns of males and females, historical demography of cultures with ancient roots, and patterns of human genetic diversity are increasingly the focus of integrated analysis by historians, anthropologists, and geneticists.

Given the geography and agroclimatic conditions of the Southeast, coupled with continued population expansion from in-migration, local foods markets may be a promising niche market for some farms in the region. The Southeast has more small farms than any other U.S. region. Using farm-level data, we address the question of how successful southeastern farms engaged in direct sales to consumers di...

Constant immigration can stabilize population size fluctuations but its effects on extinction remain unexplored. We show that constant immigration significantly reduced extinction in fruitfly populations with relatively stable or unstable dynamics. In unstable populations with oscillations of amplitude around 1.5 times the mean population size, persistence and constancy were unrelated. Low immi...

For American workers, immigration is primarily a redistributive policy. Economic theory predicts that immigration will redistribute income by lowering the wages of competing American workers and increasing the wages of complementary American workers as well as profits for business owners and other “users” of immigrant labor. Although the overall net impact on the native-born is small, the loss ...

Abstract We focus on one of the most salient policy issues our time, immigration, and evaluate whether salience immigration in governing parties’ manifestos translates into actual legislative activity immigration. contend that democratic policymakers have genuine incentives to do so. Furthermore, we argue country context matters for pledge fulfillment, find migration more strongly when level re...
