In this paper we formalize budgetary stabilizers as a set of simple policy rules, and assess their operation in an uncertain environment by performing stochastic simulations in a forward-looking multi-country macroeconomic model, NiGEM, comprising individual blocks for 10 Euroland economies.

We consider a problem faced by a contract assembler that both assembles finished goods and procures the associated component parts for one of its major customers. Because of rapid changes in technology and ongoing engineering changes, all parts subject to obsolescence are purchased only for the...

Results from poverty studies are sensitive to the choice f the poverty line. Poverty dominance analysis uses stochastic dominance to provide rankings of distributions in terms of poverty which are not sensitive to the choice of poverty lines or which at least give an unambiguous results over a...

In this paper we construct a dynamic stochastic general equilibrium model for a small open economy allowing for perfect capital mobility. The model incorporates price rigidities in monopolistically competitive goods and labor markets and real rigidities in the form of capital adjustment costs....

SETSTOCH is a tool for linking Algebraic Modeling Languages with Specialized Stochastic Programming Solvers. Its main role is to retrieve from the modeling language a dynamically ordered core model (baseline scenario) that is then sent automatically to the Stochastic Solver. The user is thus...

In this paper we construct a dynamic stochastic general equilibrium model for a small open economy allowing for perfect capital mobility. The model incorporates price rigidities in monopolistically competitive goods and labor markets and real rigidities in the form of capital adjustment costs....

This paper first provides some useful results on a generalized random coefficient autoregressive model and a Markov plus i.i.d. noise model. These results simultaneously imply strict staionarity, existence of higher-order moments, goemetric ergodicity and b-mixing with exponential decay rates,...

The purpose of this paper is to study unfunded social security systems in the framework of an economy submitted to demographic and technological shocks. The emergence of transfers between generations rests on a motive of rreal and possible inequalities correction or on a portfolio choice.

This paper develops a tractable stochastic overlapping generations model to analyze the equilibrium equity premium and growth rate of the capital stock in the presence of a defined-benefit Social Security system. If the Social Security Trust Fund increases the share of its portfolio held in...

A generalization of the endogenous threshold model is developed by extending this class to multivariate framework and to cases where the feedback acts at multiple lags. The feedback is specified, following Beaudry and Koop, by a variable which measures the depth of recessions. We give conditions...
