We analyze the characteristics of optimal dynamics in an economy in which neither prices nor wages adjust instantaneously and lump-sum taxes are unavailable as a source of government finance. We then propose that monetar and fiscal policy should be coordinated to satisfy a pair of simple...

The optimal policy mix maximizes a quadratic welfare objective which follows from the agents’ utility function and depends only on inflation and output gap volatility. We analyze the optimal response of the economy to a rise in government spending. We find that the optimal economy moves...

This paper shows that numerical solutions to models with incomplete markets and aggregate uncertainty obtained using the Krusell and Smith (1998) algorithm are sensitive to the parameterization of the grid in the aggregate asset holdings direction. Higher moments of the cross-sectional...

Economic theory has yet to come up with a general guidance regarding the dynamic effects and welfare implications of shocks to public spending. With the aim to provide a theoretical benchmark, we analyze if a rise in private consumption following an exogenous rise in government spending is a...

The study critically analyzes the weak points of current fiscal institutions in Slovakia, while proposing a new institutional framework. It is based on the concept of the net worth and reflects international experience. The main part of the proposal is additional fiscal rules to the Stability...

This paper shows that grid-based numerical solutions to models with incomplete markets and aggregate uncertainty are sensitive to the number and placement of grid points in the aggregate asset holdings direction. Higher moments of the cross-sectional distribution of asset holdings can be...

Economic theory has yet to come up with a general guidance regarding the dynamic effects and welfare implications of shocks to public spending. With the aim to provide a theoretical benchmark, we analyse if a rise in private consumption following an exogenous rise in government spending is a...

Recent risk sharing tests strongly reject the hypothesis of complete markets, because in the data: (1) the individual consumption comoves with income and (2) the consumption dispersion increases over the life cycle. In this paper, I revisit the implications of these risk sharing tests in the...

I develop an equilibrium model with collateral constraints in which rational agents are uncertain and learn about the equilibrium mapping between fundamentals and collateral prices. Bayesian updating of beliefs by agents can endogenously generate booms and busts in collateral prices and largely...

Various papers have identified shocks to investment as major drivers of output, investment, hours, and interest rates. These investment shocks have been linked to financial frictions because financial markets are instrumental in transforming consumption goods into installed capital. However, the...
