In priciple random portfolios should be uniformly distributed over the feasible region. Common algorithms tend to concentrate portfolios near the boundary. While there is an argument that this may actually be better than a uniform distribution, it is of interest to know what difference the...

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 study focuses on the role of the order book on price formation in financial markets. It employs a computational model inspired by Gode and Sunder's Zero Intelligence Framework to investigate the effect of the supply and demand schedules of traders in this context. From this model insight is...

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,...

The transition from economic stagnation to sustained growth is often modelled thanks to "population-induced" productivity improvements, which are assumed rather than derived from primary assumptions. In this paper, the effect of population on productivity is derived from optimal behavior. Both...

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...
