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...

This paper analyzes effects of tax-favored savings plans on savings and retirement decisions in a realistically specified life-cycle model. Individuals face mortality risk and stochastic earnings, allocate assets between conventional savings accounts (CSAs) and tax-deferred accounts (TDAs), make...

Many have questioned the empirical relevance of the Calvo-Yun model. This paper appends three widely-studied macroeconomic models (Calvo-Yun, Hybrid and Svensson) with forward rate curves. We back out from observations on the yield curve the underlying macroeconomic model that most closely...

This paper deals with the sustainable management of a renewable resource based on individual and transferable quotas (ITQs). The aim of that paper is to determine the conditions under which a regulating agency can achieve both ecological and economic objectives when agents are heterogenous and...

We present a fully integrated microsimulation-AGE model that uses the labour market model PACE-L and data from the German Socio-Economic Panel. We use the model to analyse reform proposals designed to encourage labour force participation at the lower end of the wage distribution. A special focus...

Sudden and protracted oil-price increases are generally accompanied by economic contractions and high inflation. How should monetary policy react to oil-price shocks in order to minimize such adverse macroeconomic effects? We build a DSGE model characterized by two oil-importing countries and...

Three methods have been developed by the authors for solving optimal experimentation problems. David Kendrick (1981, 2002, Ch.10) uses quadratic approximation of the value function and linear approximation of the equation of motion to simulate general optimal experimentation (active learning)...

This paper examines the effect on economic growth and welfare of the access to external financing which results in technological transfers to a developing country from the rest of the world. We consider a two-sector stochastic growth model and compute optimal accumulation mechanisms in the...

In this paper we ask whether policies targeting a reduction in crime rates through changes in education outcomes can be considered an effective and cost-viable alternative to interventions based on harsher punishment alone. In particular we study the effect of subsidizing high school completion....

We present an optimal (Ramsey) social security policy analysis in the presence of demographic uncertainties and incomplete markets. According to our findings, a social security system is an efficient instrument for intergenerational risk-sharing. When compared with government debt, a...
