This article studies the e¤ect of limited commitment on stock return volatility in a dynamicgeneral equilibrium economy populated by investors with heterogeneous beliefs. Due to het-erogeneity of beliefs investors disagree about the fundamentals, introducing an additional riskfactor denoted...

We study in a general perspective the partial equilibrium incentives and the general equilibrium asset pricing implications of Value-at-Risk (VaR) regulation in continuous time economies with intermediate consumption, stochastic opportunity set, and heterogenous attitudes to risk. Our findings...

We present an object-oriented software framework allowing to specify, solve, and estimate nonlinear dynamic general equilibrium (DSGE) models. The implemented solution methods for finding the unknown policy function are the standard linearization around the deterministic steady state, and a...

We present a comprehensive framework for Bayesian estimation of structural nonlinear dynamic economic models on sparse grids. The Smolyak operator underlying the sparse grids approach frees global approximation from the curse of dimensionality and we apply it to a Chebyshev approximation of the...

We model multiyear loss distributions based on credit scores and macroeconomic risk drivers. In a two-step approach, we first model future default probabilities as functions of these risk factors and, second, model processes for the risk factors themselves. As an essential extension to one-year...

Veränderungen in der Erwerbslandschaft, der demographische Wandel und die Globalisierunggelten neben anderen Einfl ussfaktoren wie derErosion der Finanzierungsbasis der sozialen Sicherungssystemeund der Staatsverschuldung als wesentlicheGründe für eine Neuausrichtung desSozialstaats. Diese...

Standard models of international risk sharing with complete asset markets predict a positive association between relative consumption growth and real exchange-rate depreciations across countries. The striking lack of evidence for this link - the consumption/real-exchange-rate anomaly or...

In this paper, we experimentally test the Modigliani-Miller theorem. Applying ageneral equilibrium approach and not allowing for arbitrage among ¯rms with differ-ent capital structure, we are able to address a question fundamental to the valuationof firms: does capital structure affect the...

We propose a simple and powerful method for determining the transition processin continuous-time DSGE models under Poisson uncertainty numerically. The idea isto transform the system of stochastic dierential equations into a system of functionaldierential equations of the retarded type. We then...
