The paper develops a simple stochastic new open macroeconomic model in which pricesetting firms' choice between producer currency pricing and local currency pricing is endogenous. We show that, in equilibrium, firms will denominate their export price contracts in the currency of the country with...

Almost all theoretical work on how to calculate the marginal deadweight loss has been done for linear taxes and for variations in linear budget constraints. This is quite surprising since most income tax systems are nonlinear, generating nonlinear budget constraints. Instead of developing the...

The first aim of this paper is to clarify the differences and rela-tionships between cumulative advantage/disadvantage and the Matthew ef-fect. Its second aim, which is also its main contribution, is not only to present a new measure of the Matthew effect, but also to show how to esti-mate this...

This paper deals with the consequences of the assumption of negatively interdependent preferences for the shape of the optimal nonlinear income tax and the effcient level of public good provision in a setting where the policy maker maximizes an inequality averse social welfare function and the...

This paper studies optimal unemployment benefit levels and optimal proportional income tax rates over the business cycle. Previous research suggests that policy makers should make unemployment insurance (UI) dependent on the business cycle because the UI system can be used to smooth consumption...

The paper extends Ng's (1987) model of optimal taxation of diamond goods - goods that are valued solely for their costliness. We extend his findings by analyzing how other goods should be taxed in the presence of pure diamond goods; modified Ramsey rules are derived in a basic single-type model...

Financial intermediation and bank spreads are important elements in the analysis of business cycle transmission and monetary policy. We present a simple framework that introduces lending relationships, a relevant feature of financial intermediation that has been so far neglected in the monetary...

The paper develops an equilibrium search and matching model where two-person families as well as singles participate in the labor market. We show that equilibrium entails wage dispersion among equally productive risk-averse workers. Marital status as well as spousal labor market status matter...

The incidence and efficiency losses of taxes have usually been analyzed in isolation from public expenditures. This negligence of the expenditure side may imply a serious misperception of the effects of marginal tax rates. The reason is that part of the marginal tax may in fact be a payment for...
