T his study investigated the effect of international labor migration on Iran’s economy using a neo-classical growth model with the assumption of labor heterogeneity within the framework of dynamic stochastic general equilibrium model. After solving the model, the obtained equations were linearized and different values were assigned to the parameters according to Iran’s economy inform...

We investigate the effect of immigration on the labor supply of skilled women, using data on Spain’s large recent immigration wave. We adopt a spatial correlations approach and instrument for current immigration using ethnic networks. We find that female immigration increases the local availability of household services and reduces their price. It also increases the labor supply of skilled nati...

This paper examines the relationship between unemployment and immigration in Canada. The bidirectional causality test finds no evidence of a significant effect of Canadian immigration on unemployment. Cointegration tests indicate that there is no observed increase in aggregate unemployment due to immigration in the long run. The results from the causality test based on the vector error correcti...

This paper considers the relationship between economic factors and national security. While considering a broad number of issue areas, the principal theme of the course is the way in which economic factors (as immigration) fundamentally influence the national security of the region, and the way in which those factors shape and constrain the strategies chosen to pursue that security. South-South...

The thermal field of the Gulf of Mexico (GoM) is analyzed from a comprehensive temperature-depth database of about 8500 Bottom Hole Temperatures and Reservoir Temperatures. Our stochastic analysis reveals a widespread, systematic sharp thermal gradient increase between 2500 and 4000 m. The analysis of the pressure regime indicates a systematic correlation between the pressure and temperature fi...

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...

Many simple population models exhibit the period doubling route to chaos as a single parameter, commonly the growth rate, is increased. Here we examine the effect of an immigration process on such models and explain why in the case of one-dimensional ("single-humped") maps, immigration often tends to suppress chaos and stabilise equilibrium behaviour or cyclical oscillations of long period. The...
