Monetary policymakers face considerable uncertainty and have to use judgment. When the monetary policy committee (MPC) has to reach a decision based on different judgments among its members, various judgment aggregation problems may occur. Here, we consider an aggregation problem called the...

Heterogeneity between unemployed and employed individuals matters for optimal fiscal policy. This paper considers the consequences of such heterogeneity for the determination of optimal capital and income taxes in a model with matching frictions in the labor market. In line with a recent finding...

This paper examines the welfare implications of managing asset-price with consumer-price inflation targeting by monetary authorities who have to learn the laws of motion for both inflation rates. Our results show that the Central Bank can reduce the volatility of consumption and asset price...

A manifestation of the Federal Reserve Board's increased transparency has been Chairman Greenspan's method of communication. The purpose of this paper is to establish the positive aspects of his speeches, testimonies and FOMC statements on financial market variables. This analysis is undertaken...

In this paper we analyze dynamic incentives of a firm to invest in production facilities in a less developed country with lower wage costs and lower productivity. Foreign investment induces that, due to technological spillovers, productivity of local firms in the foreign country increases. Firms...

In practical portfolio choice models risk is often defined as VaR, expected shortfall, maximum loss, Omega function, etc. and is computed from simulated future scenarios of the portfolio value. It is well known that the minimization of these functions can not, in general, be performed with...

This paper proposes Lagrange Multiplier based panel unit root tests allowing for structural breaks through simple extensions of existing group mean and combination tests. The proposed tests are more general than those previously suggested. They consider potential breaks in the intercept, in the...

One important factor concerning economic models is that frequently large amounts of data are produced. There is the research issue of how end-users (who may not be researchers or model developers) can be presented with this data so that maximum benefits can be attained from the data production....

This paper adds oil prices to an estimated DSGE model for the euro area. The price of oil is an important macroeconomic driving factor for most industrialised countries. The euro area is importing most of its oil from abroad; therefore changes in oil prices have effects on domestic income via the...

A common approach to evaluate dynamic stochastic general equilibrium (DSGE) models is to compare the impulse responses functions from the DSGE model to impulse responses obtained from identified vector autoregressions (VARs). This paper uses Monte Carlo techniques to address the question: Are...
