The implicit association test (IAT) measures bias towards often controversial topics (race/religion), while newspapers typically take strong positive/negative stances on such issues. In a pre-registered study, we developed and administered an immigration IAT to readers of the Daily Mail (typically anti-immigration) and Guardian (typically pro-immigration) newspapers. IAT Materials were construc...

This paper analyses the impact of immigration on the welfare of the native population in an economy that consists of skilled and unskilled workers. Due to unionisation, the wage rate in the market for unskilled labour is above the competitive level. For a given skill endowment of the native population, we show that immigration reduces the welfare of the host country up to a certain threshold an...

This article reflects on fieldwork experiences with coethnic migrants in London to challenge understandings of insiderness centred in shared ethnicity, as well as the usefulness of the insider-outsider divide in migration research more generally. Drawing on examples from a study of migrants' social relations, it shows how gender, migrant status, and occupational position sometimes shape researc...

How individuals migrate over long distances is an enduring mystery of animal migration. Strong selection pressure for travelling in groups has been suggested in long-distance migrating species. Travelling in groups can reduce the energetic demands of long migration, increase navigational accuracy and favour group foraging at migratory halts. Nevertheless, this hypothesis has received scant atte...

This paper quantifies the effects of trade liberalization on local labor market outcomes and workers’ migration patterns. I extend the classic specific-factors model to examine the impact of national price changes on local labor markets. The model describes how tariff changes across industries affect wages in local labor markets within the liberalizing country. In particular, wages will fall in...

Three main hypotheses have been postulated over the past century to explain the outbreaking population dynamics of eastern spruce budworm, Choristoneura fumiferana (Clemens). The Silviculture Hypothesis first arose in the 1920s, with the idea that outbreaks were driven by forestry practices favoring susceptible softwood species. In the 1960s, it was proposed that populations were governed by Mu...

Genetic diversity is essential for population survival and adaptation to changing environments. Demographic processes (e.g., bottleneck and expansion) and spatial structure (e.g., migration, number, and size of populations) are known to shape the patterns of the genetic diversity of populations. However, the impact of temporal changes in migration on genetic diversity has seldom been considered...

Mass movement of people over national borders constitutes the major feature of the today's world. Immigration and its implications are widely debated, whereby the term 'immigration', whenever appeared in a text, hardly ever refers to some unambigously defined concept. To deal with the question of immigration is, therefore, to be faced with a variety of definitions and connotations. The thesis c...

Data from Princeton University’s New Immigrant Survey were analyzed to examine the associations between immigrants’ media use and 3 indicators of acculturation—current English proficiency, preference to use English in interactions, and American political knowledge. Findings show that pre-immigration uses of English language TV, radio, and print media and post-immigration use of English language...
