Recent literature on the workhorse model of intra-industry trade has explored heterogeneous cost structures at the firm level. These approaches have proven to add realism and predictive power. This note shows, however, that this added realism also implies that there may exist a positive...

This paper investigates the elusive role of productivity heterogeneity in new trade models in the trade and environment nexus. We contrast the Eaton-Kortum and the Melitz models with firm heterogeneity to the Armington and Krugman models without heterogeneity. We show that if firms have a...

In this paper, we use a computable general equilibrium model (WIATEC) to study the potential impact of implementing Europe's 20-20-20 climate policy. The results show that the economic costs of implementing the policy are only moderate and within the range of recent empirical evidence....

This paper provides new evidence on migrant networks as determinants of the total size (scale) and skill structure of migration, using aggregate data from a recent migration boom to Spain. We draw upon McFadden (1984, 1422-1428) in order to develop and apply a three-level nested multinomial...

This paper sets up a two country monopolistic competition model with intra-industry trade to study the effects of an exogenous differential in wage and social policies on the location of industry. Two model scenarios are considered. In the traditional one with physical capital, such a...

Tax competition for a mobile factor is different in 'new economic geography set- tings' compared to standard tax competition models. The agglomeration rent which accrues to the mobile factor in the core region can be taxed. Moreover, a tax differential between the core and the periphery can be...

In this paper we study the determinants of international migration to Germany, 1967-2000. The empirical literature on macro-economic migration functions usually explains migration flows by a set of explanatory variables such as the income differential, employment rates, and migrations stocks as...

European Union economies are pressed by (i) a demographic change that induces population ageing and a decline of the workforce, and (ii) a split labour market that is characterized by high levels of unemployment for low -skilled people and a simultaneous shortage of skilled workers. This lack of...

In this study we analyse the impact of workers' remittances on the decision to migrate by means of cointegration analysis. In traditional migration theories, especially in human capital models, the decision to migrate is based upon comparison of expected future incomes in the sending and the...

The determinants of migrants? remittances are the subject of this study based on German SOEP data. For our analysis of the probability and amount of remittances, we do not restrict ourselves on immigrants with a foreign citizenship, but focus on all individuals with a migration background. Major...
