This paper presents a network model incorporating customer satisfaction into efficiency and productivity measures. The network consists of a production node and a consumption node and offers flexibility in modelling the production and consumption process. Allocation of input resources to...

We survey several key mechanisms that explain the composition of international capital flows: foreign direct investment, foreign portfolio investment and debt flows (bank loans and bonds). In particular, we focus on the following market frictions: asymmetric information in capital markets and...

Migrants, being relatively low earners, are net beneficiaries of the welfare state. However, this paper uses a dynamic model to show that because of migrants’ positive influence on the pension system, which is an important pillar of any welfare state, migration could be beneficial to all...

The extent of taxation and redistribution policy is generally determined at a political-economy equilibrium by a balance between those who gain and those who lose from a more extensive tax-transfer policy. In a stylized model of migration and human capital formation, we find, somewhat against...

The paper studies determinants and consequences of sharp reductions in current account imbalances (reversals) in low- and middle-income countries. It poses two questions: what triggers reversals, and what factors explain how costly reversals are? It finds that both domestic variables, such as...

This paper distinguishes between debt and equity flows in the presence of information asymmetry between the firm’s “insiders” and “outsiders” in a small open economy. It shows the inadequacy of capital investment because its scope is too narrow and the investment each firm makes is too...

Even though financial markets today show a high degree of integration, the world capital market is still far from the textbook story of high capital mobility. The purpose of this paper is to highlight key sources of market failure in the context of international capital flows and to provide...

Data for the United States and countries in Western Europe indicate a negative correlation between the dependency ratio and both labor tax rates and the generosity of social transfers, after controlling for other factors that influence the size of the welfare state. This is despite the increased...

Identifying determinants of the output-inflation tradeoff has long been a key issue in business cycle research. We provide evidence that in countries with greater restrictions on capital mobility, a given reduction in the inflation rate is associated with a smaller loss in output. This result is...
