Ce modèle étudie les effets joints de l'irréversibilité et des coûts de faillite sur la décision d'investissement. Les coûts de faillite supportés par le prêteur accentuent son conflit d'intérêt avec l'emprunteur: il est principalement concerné par la partie basse de la distribution...

An ECM is derived from first order conditions of a factor demand model. Decisions on inventory stock and capacity utilization are (endogenously) modelled, by which a large systems of equations results. Within this system the exogeneity of real factor prices as well as sales in tested. The role...

In this paper, the public investment provision takes place in a stochastic environnement. The role of the government is to remove a part of the uncertainty faced by the firm. If the government simply maximizes the value of the firm, then the optimal tax is smaller under imperfect competition...

We use a two-sector neoclassical open economy model with traded and non-traded goods to investigate both the aggregate and the sectoral effects of temporary fiscal shocks. One central finding is that both sectoral capital intensities and labor supply elasticity matter in determining the response...

We use a neoclassical open economy model with traded and non traded goods to investigate the sectoral effects of three tax reforms: i) two revenue-neutral shifting the tax burden from labor to consumption taxes and ii) one labor tax restructuring keeping the marginal tax wedge constant....

We construct a vintage capital model à la Whelan (2002) with both exogenous embodied and disembodied technical progress, and variable utilization of each vintage. The lifetime of capital goods is endogenous and it relies on the associated maintenance costs. We study the properties of the...

We study an optimal growth model with one-hoss-shay vintage capital, where labor resources can be allocated freely either to production, technology adoption or capital maintenance. Technological progress is partly embodied. Adoption labor increases the level of embodied technical progress....

We study optimal growth model à la Nelson and Phelps (1966) where labor resources can be allocated either to production, technology adoption or capital maintenance. We first characterize the balanced growth paths of a benchmark model without maintenance. Then we introduce the maintenance...

We use two stage optimal control techniques to solve some adoption problems under embodied technical change. We first solve a benchmark problem without learning behavior. At the date of switching, the consumption level is shown to drop, as the relative price of capital goes down (obsolescence)....

This paper derives the optimal pace of capital accumulation at the firm level and the corresponding investment dynamics in the presence of an energy-saving technological progress. Energy and capital are complementary. When technical progress is disembodied, the firm invests once at the first...
