This paper investigates the influence of clean-up subsidies on the dynamics of models of production-environment interaction in continuous time. We show that complex dynamics can arise in the cases of socially optimal and decentralised solutions. Thus, it is possible that pollution can increase...

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,...
