Cross-sectoral pollution externalities and multiple equilibriaJournal articleLarry Karp et Thierry Paul, Environment and Development Economics, Volume 24, Issue 6, pp. 624-642, 2019

In familiar models, a decrease in the friction facing mobile factors (e.g., lowering their adjustment costs) increases a coordination problem, leading to more circumstances where there are multiple equilibria. We show that a decrease in friction can decrease coordination problems when a production externality arises from a changing stock, e.g. of pollution or knowledge. In general, the relation between the amount of friction that mobile factors face and the likelihood of multiple equilibria is non-monotonic.

Indeterminacy with environmental and labor dynamicsJournal articleLarry Karp et Thierry Paul, Structural Change and Economic Dynamics, Volume 18, Issue 1, pp. 100-119, 2007

We study the joint dynamics of labor reallocation and environmental change when workers have rational expectations and incur migration costs. We emphasize the relation between parameter values and the area of state space in which indeterminacy of equilibria can occur. Unlike the one-dimensional model in which the wage differential adjusts instantaneously, here the measure of the region of indeterminacy is not monotonic in the cost of adjustment.

L'effet taille de marché un réexamen du modèle de Helpman-Krugman et de quelques extensionsJournal articleDidier Laussel et Thierry Paul, Revue d'économie politique, Volume 115, Issue 5, pp. 545-560, 2005

The objective of this article is to bring a new light to the literature on the ?home market effect? based on the pioneering article by Helpman and Krugman (1985). We present some works which show that the existence of net trade between two countries of different sizes, the trade structure and the pattern of specialization can highly depend on the relative size of the large country.
