We consider a production stage that produces a single item in a make-to-stock manner. Demand for finished goods is stationary. In each time period, an updated vector of demand forecasts over the forecast horizon becomes available for use in production decisions. We model the sequence of forecast...

Forward and backward stochastic Lagrangian trajectory simulation methods for calculation of the mean concentration of scalars and their fluxes for sources arbitrarily distributed in space and time are constructed and justified. Generally, absorption of scalars by medium is taken into account. A...

We study the prospective operation of the Stability Pact by stochastic simulation. Using a forward-looking multi-country macroeconometric model, NiGEM, comprising individual blocks for 10 Euroland economies, the Pact's provisions are formalized in detail, and alternative monetary and fiscal...

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.

This paper aims to study whether a simple asymetric adjustment costs model with heterogeneity can account for French aggregate job flows.

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...

A standard approach to duality in stochastic optimization problems with constraints in L(infinite) relies upon the Yosida-Hewitt theorem. We develop an alternative technique which employs only "elementary" means. The technique is based on an e-regularization of the original problem and on...

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...

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....
