We present a multi-stage stochastic programming model for managing portfolios of stock and bond indices denominated in multiple currencies. The portfolios are exposed to market risks and currency risks. Uncertainty in asset returns and exchange rates is represented by means of discrete...

By following the spirit in Favero and Milani (2005), we use recursive thick modeling to take into account model uncertainty for the choice of optimal monetary policy. We consider an open economy model and generate multiple models for only the aggregate demand and aggregate supply. Models are...

Dynamic models with inequality constraints pose a challenging prob- lem for two major reasons: Dynamic Programming techniques often necessitate a non established differentiability of the value function, while Euler equation based techniques have problematic or unknown convergence properties....

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...

Following the lead of Merton (1974), recent research has focused on the relationship of credit risk to firm value. Although this has usually been done for a single firm, the growth of structured finance, which necessarily involves the correlation between included securities, has spurred interest...

A distributed system model is studied, where individual agents engage in repeated play against each other and can change their strategies based upon previous play. Similar to Dorofeenko and Shorish (2005), it is shown how to model this environment in terms of continuous population densities...

Paper deals with a simulation of job-search models using simulated annealing (SA). It is standard to test Burdett-Mortensen on-the-job search model which gives a unique solution. Unfortunately, its later generalizations especially incorporation of heterogeneous agents has overcome this unique...

Contemporary economics contains mainly two approaches for an explanation of fluctuations of economic activity indicators. The first approach expresses fluctuations as the expression of an environment that is fundamentally uncertain and subject to random external shocks. The second approach...

Indicators and their associated reference points are key elements of current fisheries management advice, as well as of the developing ecosystem approach to it, especially in the International Council for the Exploration of the Sea precautionary approach. However, although sustainable management...

In this paper we analyze dynamic incentives of a firm to invest in production facilities in a less developed country with lower wage costs and lower productivity. Foreign investment induces that, due to technological spillovers, productivity of local firms in the foreign country increases. Firms...
