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...

Various volatility estimators and models have been proposed in the literature to measure volatility of asset returns. The particular emphasis of this paper is on assessing empirical performance of various long memory models (ARFIMA, FIGARCH models, and MF multi-fractal model which has recently...

This paper presents a fully rational general equilibrium model that produces a time-varying exchange rate risk premium and solves the uncovered interest rate parity (U.I.P) puzzle. In this two-country model, agents are characterized by slow-moving external habit preferences similar to Campbell &...

DSGE models are customarily built in the presence of uncertainties of various levels, such as the specification of behavioural equations of economic agents, the actual values of model parameters, and so on. When the degree of complexity of the model structure and its parameterization increases,...

Particle swarm optimization (PSO) is a population based stochastic optimization technique. PSO is similar to optimization with Genetic Algorithms (GA). In PSO, the potential solutions (particles) move through the problem space by following the current optimum particles. Experience shows that PSO...

In the standard models of North-South technological-knowledge diffusion, the larger the initial technological-knowledge gap between countries is, the higher the Southern catching up. However, this result does not adjust well to Southern reality as a whole. The purpose of this paper is to...

The problem of convexity runs deeply in economic theory. For example, increasing returns or upward slopes (convexity) and diminishing returns or downward slopes (concavity) of certain supply, demand, production and utility relations are often assumed in economics. Quite frequently, however, the...

Since their introduction Kernel Methods have proven their superior performance in many different application areas. Recently these algorithms have also been employed for different tasks in the area of finance. In this contribution we present an introduction to the methodology and give an...

We consider the classical prisoner's dilemma being played repeatedly on a dynamic network, where agents may choose their actions as well as their co-players. Agents act profit-maximizing, fully rationally and base their decision only on local information. Individual decisions are made such that...

We study the role of nonlinear simple rules for monetary policy. We depart from the standard rules proposed by Taylor (1993), and consider a nonlinear rule for the so-called opportunistic approach to disinflation originally proposed by Orphanides and Wilcox (2002) and Aksoy, Orphanides, Small,...
