This paper assesses the importance of heterogeneity in household portfolios for transmission monetary policy a New Keynesian business cycle model with uninsurable income risk and assets different liquidity. In this environment, works through investment, but redistribution lowers elasticity investment via two channels: (i) marginal propensities to invest, (ii) time variation liquidity premium. M...

We study the interaction between monetary and fiscal policies in a Ramsey-Sidrauski model augmented with environmental capital. Equilibrium solutions are studied through “Green Golden Rule”. Despite non-separability of money utility intertemporally non-separable preferences, is environmentally neutral. Policy impacts environment via marginal rate transformation rather than substitution consumpt...

We perform a series of Monte Carlo experiments in order to evaluate the impact of data transformation on forecasting models, and ̄nd that vector error-corrections dominate di®erenced data vector autoregressions when the correct data transformation is used, but not when data are incorrectly tansformed, even if the true model contains cointegrating restrictions. We argue that one reason for this ...

Based on monthly observations, I specify an econometric model capturing the driving forces behind the crude oil price series in recent years. A large set of covariates, such as supply and demand variables as well as futures market variables, is used to test the impact on the crude oil price. Current price movements are a result of scarce refining capacity and speculators betting on higher price...

The paper suggests a CUSUM-type test for time-varying parameters in a recently proposed spatial autoregressive model for stock returns and derives its asymptotic null distribution as well as local power properties. As can be seen from Euro Stoxx 50 returns, a combination of spatial modelling and change point tests allows for superior risk forecasts in portfolio management. JEL Classification: C...
