I develop a model of an R&D race in which firms learn and forget. The firm which makes a discovery first is awarded a prize. Firms compete to be the first by investing in R&D. As a by-product of its R&D effort, a firm accumulates knowledge. This knowledge stock is valuable even if success is not...

The LLS stock market model (for a review see the book in Academic Press 2000: "Microscopic Simulation of Financial Markets; From Investor Behavior to Market Phenomena" by Levy, Levy and Solomon, ISBN: 0124458904) is a model of heterogeneous quasi-rational investors operating in a complex...

The natural rate of interest -- the real interest rate consistent with output equaling potential -- plays an important role in both economic forecasting and monetary policy. Much of the literature has assumed that the natural rate of interest is constant. For example, the Taylor rule includes a...

This paper extends the framework provided by Aksoy, De Grauwe, Dewachter (2000). We first provide an econometric analysis of the stabilising properties of the monetary policy in the EMU countries within an open economy framework and obtain optimal feedback rules for monetary policymaking. In a...

This paper develops a real business cycle model characterized by a large number of agents facing idiosyncratic employment shocks and borrowing constraints. In particular, I use numerical methods to study the statistical properties of aggregate variables in equilibrium under both complete and...

While the conditional volatility of time series is always dependent of the model specification, the {\\em ex post} or realized volatility series is often constructed on a model-free basis. The common proxies of daily volatility in the literature are the squared daily asset returns and the sum of...

Background This paper is a continuation of our investigation of the paradox of technical analysis in the stock market (Fyfe, Marney and Tarbert (1999), Marney et. al (2000)). The Efficient Markets Hypothesis (hereafter the EMH) holds that there should be no discernible pattern in share price...

For many environmental problems regulators are uncertain about both the costs of abatement and the stock-related damages. For example, governments have imperfect information about damages caused by greenhouse gas stocks, and also about the costs of abating greenhouse gas emissions. They acquire...

In this paper, we propose use of the influence diagram for stock portfolio selection. We use an algorithm that applies the mutual information as the metric to guide the refinement of the influence diagram. We applied the algorithm to the conceptual refinement of the influence diagram. We tested...

Anderson's papers describe a method for solving linear saddle point models. The numerical implementation of the algorithm has proved useful in a wide array of applications including analyzing linear perfect foresight models, and providing initial solutions and asymptotic constraints for...
