Constitutional structures shape politicians' behaviour and hence policy outcomes through the di fferent incentive schemes at work. In this paper we analyse these mechanisms in parliamentary and presidential systems. Such a comparison is carried over by analysing how the two systems are able to...

This paper shows that different labor market policies can lead to differences in technology across sectors in a model of labor saving technologies. Labor market regulations reduce the skill premium and as a result, if technologies are labor saving, countries with more stringent labor regulation,...

We investigate the effects of credit ratings-contingent financial regulation on foreign bank lending behavior. We examine the sensitivity of international bank flows to debtor countries' sovereign credit rating changes before and after the implementation of the Basel 2 risk-based capital...

A general equilibrium model featuring multiple realistic sources of financial frictions is developed to study how different constraints interact in equilibrium. We highlight, distinguish, and evaluate their differential impacts and rich interactions. The economic impact of financial inclusion...

Proposed issues in social entrepreneurship, as most of the issues in social sciences are abstract ones. For the performance assessment and implementation of timely controlling and compensatory measures, we need an effective, concrete and comprehensive model in social entrepreneurship. The aim of...

This paper surveys the literature on fiscal competition. We consider tax and expenditure competition in a more general set up where different jurisdictions within a federation may compete in the provision of public goods in order to attract some residents (Tiebout, 1956) and expel others...

This paper investigates the coherent risk measure of normal mixture distributions. The main result shows that the mean-risk portfolio optimization problem of some widely-used normal mixture distributions can be reduced to a quadratic programming problem which has closed form of solution by...

This paper analyses a time discrete multiperiod CAPM which in terms of portfolio selection is only based on mean-variance behavior and does not hinge on expected utility maximization. Portfolio returns are not required to be elliptically distributed but merely need to have finite variance. Two...
