The paper focuses on short run macroeconomic dynamics triggered by demand side shocks. In particular, the paper analyzes, in a general equilibrium framework, the impact of transitory demand side shocks on the behavior of macroeconomic variables and examines the relevance of policy instruments...

Fluctuations of representative agent economies are not very costly. So if business cycles matter, it must be because agents face uninsured idiosyncratic risk which is somehow worsened by aggregate fluctuation. Idiosyncratic risk could be counteracted either through aggregate stabilization or...

This paper studies the welfare effects of monetary and fiscal policy rules, in a dynamic general equilibrium model with sticky prices. The model features capital accumulation and endogenous labor effort, and exogenous productivity shocks. Government purchases are valued positively by the private...

On the basis of a model on time consistent interaction of monetary and fiscal policy, we propose a positive theory of government debt and inflation. The basic take is that the long-term level of public liabilities can be explained as the endogenous outcome of a dynamic game played between two...

Using a simple stochastic multi-sector model we show patterns of demand shares on sectors with different productivity coefficients have some expected and some unexpected effects on GDP, sector sizes, the magnitudes of the Okun's law coefficients, and Beveridge curves shifts. The basic stochastic...

This paper contrasts the effects of tied and untied foreign aid programs on the welfare and macroeconomic performance of a small open economy. We show that the acceptance of tied aid inevitably obligates the recipient economy to undertake certain internal structural adjustments, and the...

There are two competing theories of balance of payments: the Keynesian and the monetary theories. Each of the two approaches provides distinct explanations on how the determinants of the balance of payments could lead to equilibrium and disequilibrium of the balance of payments account and both...

The paper develops a theoretical model of endogenous wealth distribution, showing that a logarithmic mean constraint in the maximum entropy formalism leads to a power law distribution. On the level of economic theory, the model implies two trade-offs: first, the higher the aggregate growth of...
