There are significant effects of changing demographics on economic indicators: growth in GDP especially, but also the current account balance and gross capital formation. The 15-24 age group appears to be one of the key age groups in these effects, with increases in that age group exerting...

The global financial crisis and the subsequent uneven recovery have underscored the need for Africa's resilience to output and other shocks originated in the rest of the world. A comparison of two regional economic communities – the East African Community (EAC) and the Southern Africa Customs...

The robust empirical finding that exporting firms are systematically different from firms thatmerely serve domestic consumers has inspired the development of a new brand of tradetheory, the theory of heterogeneous firms and trade. The establishment of a canonical modeldue to Melitz (2003) has...

This paper explores the role of country asymmetries for trade and industrial policies with heterogeneous firms. Our analysis delivers a number of novel results. First, trade policies, infrastructure policies and industrial policies which improve the business conditions in one country have...

The robust empirical finding that exporting firms are systematically different from firms that merely serve domestic consumers has inspired the development of a new brand of trade theory, the theory of heterogeneous firms and trade. The establishment of a canonical model due to Melitz (2003) has...

This paper uses an oligopoly model with heterogeneous firms to examine how an industry adjusts to rising import competition. The model predicts that in the short run the least efficient firms in the industry become inactive, surviving firms face a fall in output, mark-ups and profits, and the...

This paper evaluates the welfare impact of observed levels of migration and remittances in both origins and destinations, using a quantitative multi-sector model of the global economy calibrated to aggregate and firm-level data on 60 developed and developing countries. Our framework accounts...

We introduce search unemployment - la Pissarides into Melitz' (2003) model of trade with heterogeneous firms. We allow wages to be individually or collectively bargained and analytically solve for the equilibrium. We find that the selection effect of trade influences labor market outcomes. Trade...

The core-periphery model by Krugman (1991) has two 'dramatic' implications: catastrophic agglomeration and locational hysteresis. We study this seminal model with CES instead of Cobb-Douglas upper tier preferences. This small generalization suffices to change these stark implications. For a wide...

We develop a new general equilibrium model of trade with heterogeneous firms, variable demand elasticities and endogenously determined wages. Trade integration favors wage convergence, intensifies competition, and forces the least efficient firms to leave the market, thereby affecting aggregate...
