Eine erste systematische, modellgestützte Untersuchung der ökologischen Steuerreform in Deutschland kommt zu moderaten bis positiven Effekten auf Wirtschaftswachstum, Beschäftigung, Energieverbrauch und CO2-Emissionen. Für die Analyse wurden zwei gesamtwirtschaftliche Modelle - ein...

Eine erste systematische, modellgestützte Untersuchung der ökologischen Steuerreform in Deutschland kommt zu moderaten bis positiven Effekten auf Wirtschaftswachstum, Beschäftigung, Energieverbrauch und CO2-Emissionen. Für die Analyse wurden zwei gesamtwirtschaftliche Modelle - ein...

This paper analyzes the effects of the implementation of a monetary union on the international transmission of monetary and fiscal policies. A dynamic three-country general equilibrium model, exhibiting monopolistic competition and sticky prices, is used to show how asymmetric monetary and...

Realized volatility is a nonparametric ex-post estimate of the return variation. The most obvious realized volatility measure is the sum of finely-sampled squared return realizations over a fixed time interval. In a frictionless market, the estimate achieves consistency for the underlying...

The 1987 market crash was associated with a dramatic and permanent steepening of the implied volatility curve for equity index options, despite minimal changes in aggregate consumption. We explain these events within a general equilibrium framework in which expected endowment growth and economic...

In Bayesian analysis of dynamic stochastic general equilibrium (DSGE) models, prior distributions for some of the taste-and-technology parameters can be obtained from microeconometric or presample evidence, but it is difficult to elicit priors for the parameters that govern the law of motion of...

We study how total factor productivity (TFP), energy prices, and the Great Moderation are linked. First we estimate a joint stochastic process for the energy price and TFP and establish that until the second quarter of 1982, energy prices negatively affected productivity. This spillover has...

This paper analyzes the relationship between stock returns and exchange rate changes in international markets and examines how well exchange rate volatility explains movements in stock market returns. The model-based predictions are evaluated on several cost functions. Results from such analysis...

Collective consumption decisions taken by the members of a household may prove inefficient. The impact of such inefficient household decisions on market performance is investigated. At one extreme, market efficiency can occur even when household decisions are inefficient, namely when household...
