Transport generates many externalities, some related to atmospheric pollution. In this paper, we focus on two: greenhouse gases, and local pollution. In the search for optimal transport policies, these two externalities have usually been analysed separately. Here, we study them jointly, in a...

This paper analyses the decision to invest to reduce the emissions of a stock pollutant under environmental uncertainty. It shows that this decision depends on the type and level of uncertainty. When uncertainty is small, there is no simple irreversibility effect because of the tension between...

This paper studies a decentralized job market model where firms (academic departments) propose sequentially a (unique) position to some workers (Ph.D. candidates). Successful candidates then decide whether to accept the offers, and departments whose positions remain unfllled propose to other...

Climate skeptics typically argue that the possibility that global warming is exogenous, implies that we should not take additional action towards reducing emissions until we know what drives warming. This paper however shows that even climate skeptics have an incentive to reduce emissions: such...

Bilateral international tax treaties govern the host country taxation for the vast majority of the world’s foreign direct investment (FDI). Of particular interest is the fact that the tax rates used under these treaties are gradually falling although the treaties themselves do not specify any...

In this paper, we analyze employment and capital adjustments using a panel of plants from Colombia. We allow for nonlinear adjustment of employment to reflect not only adjustment costs of labor but also adjustment costs of capital, and vice-versa. Using data from the Annual Manufacturing Survey,...
