Optimal Immigration Policy: Permanent, Guest-Worker, or Mode IV? Immigration continues to be on the forefront of the policy debate on both sides of the Atlantic. A number of reforms of permanent and guest-worker (GW) immigration programs are being considered, and the temporary movement of service providers under Mode IV (GATS) is being negotiated at the Doha Round of the WTO. This paper contrib...

This study contributes to the recent debate on immigration and unemployment in Australia by investigating the causal linkage between immigration and unemployment. The question of whether `immigrants rob jobs' is examined by identifying the sources of unemployment through causal linkages between unemployment and other key variables such as immigration. The research finds no Granger causality bet...

Immigration and Housing Rents in American Cities Is there a local economic impact of immigration? Immigration pushes up rents and housing values in US destination cities. The positive association of rent growth and immigrant inflows is pervasive in time series for all metropolitan areas. I use instrumental variables based on a “shift-share” of national levels of immigration into metropolitan ar...

Immigration and Labor Productivity: New Empirical Evidence for Spain The purpose of this paper of this paper is to explore the immigration and productivity in Spain. We estimate the effect of immigration on labor productivity from 2004 until 2008 for Spain. Using firms (SABI) and individuals data (Social Security Records) we calculate the effect by sector and municipality for the two big Spanis...

Public discourse concerning immigration and immigration policy often relies on the characterization and universalization of the threats that are posed by increasing immigration. It is the specification and reference to these threats that allows one to consider immigration as ―moral panic.‖ It is through this lens, that I undertake a content analysis of letters to the editor that appeared in a l...

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...
