We present an object-oriented software framework allowing to specify, solve, and estimate nonlinear dynamic general equilibrium (DSGE) models. The imple- mented solution methods for nding 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. TheSmolyak operator underlying the sparse grids approach frees global approximation from the curse of dimensionality and we apply it to a Chebyshev approximation of the...

This paper presents the software framework JStatCom which is geared towards the development of rich GUI clients for numerical procedures. The concept is to solve all recurring tasks with the help of reusable Java components. Optionally, one can delegate the execution of special numerical...

We use quantifiers and selection functions to represent simultaneous move games. Quantifiers and selection functions are examples of higher-order functions. A higher order function is a function whose domain is itself a set of functions. Thus, quantifiers and selection func- tions allow players...

We use quantifiers and selection functions to generalize the classical economic approach to choice. Our framework encompasses preference and utility based approaches as special cases, but also extends to non-maximizing behavior and context-dependent motives such as social concerns. We adapt the...

We present a novel coalgebraic formulation of infinite extensive games. We define both the game trees and the strategy profiles by possibly infinite systems of corecursive equations. Certain strategy profiles are proved to be subgame perfect equilibria using a novel proof principle of predicate...

EMU driven interest rate convergence has led to a significant reduction of borrowing costs for some European governments in the second half of the nineties. The paper deals with the possible consequences for deficit behaviour. Although the impact of interest rates on deficits is a crucial...

A welfare analysis of a risky policy is impossible within a linear or linearized model and its certainty equivalence property. The presented algorithms are designed as a toolbox for a general model class. The computational challenges are considerable and I concentrate on the numerics and...

This paper presents an attempt to solve and estimate a structural dynamic non-linear rational expectation model. The main contribution of this paper is to explore the Smolyak operator for numerical approximation and integration in a generic model class which do not suffer exponentially but only...

We provide a computational economics seminar at the University of Mannheim since two years. An introduction to numerics is given in around six sessions where we present the first six technical chapters of Miranda/Fackler: Applied Computational Economics and Finance (linear and nonlinear systems,...
