This paper studies models where the correspondences (or functions) under consideration are never increasing (or weakly decreasing) in endogenous variables, and weakly increasing in exogenous parameters. Such models include games of strategic substitutes, and include cases where additionally,...

When, in a supply chain, a supplier and a buyer have the choice of transaction form to do business, the equilibrium transaction form which emerges is much more constrained than previously envisaged in literature. In this paper, two forms of long-term supply contracts and procurement in the spot...

The present paper studies the impact of information sharing and contractual instruments on a shipper and her transport suppliers through a monte carlo simulation. After reviewing the literature, we propose a model to measure the benefits in terms of expected transport cost and variance of this...

Uncertainty represented by volatilities in equity markets has been observed to be time-variable and lead output fluctuations. In the rational expectation framework, uncertainty with this nature needs exogenous variables with time-varying volatilities, but technology, tastes and fiscal and...

A model of capital service is constructed on stylized consumer behaviour and the total quantity of financial resources. The demand for money becomes a function of the wage rate under agreement as well as interests rates and overall economic activity.

This paper considers a two-country world where the population in one country grows faster than the other, and investigates the implications of the addition of non-stationary population dynamics to a simple 2- commodity, 2-factor model of international trade within an overlapping- generations...

An overlapping generations model with two production factors and two types of agents is considered in presence of …nancial intermediation. The research focuses at the analysis of the consequences of a suddain negative production shock on a …nancial intermediation capacities and consequently...
