This paper scrutinizes the effects of investor-state dispute settlements (ISDS) and national treatment provisions in a two-period model where foreign investment is subject to domestic regulation and a holdup problem. It shows that ISDS can mitigate the holdup problem and increases aggregate...

We extend the literature on local income tax competition by allowing for inter-jurisdictional spillovers and imperfect rivalry in consumption of a publicly provided good. Comparing decentralized second-best results of a theoretical model with an efficient benchmark, we identify three...

We analyse a card payment system to assess the economic impact of the interchange fee. This fee is paid by the bank of the merchant, the acquirer, to the bank of the consumer, the issuer. We build up a mode in order to explore whether the interchange fee can enhance the participation to the...

An important issue in public policy debates is the effect of international migration on welfare in source and host countries. We address this issue by constructing a general equilibrium model of a two-class source or host country. Each country produces many traded and non-traded goods, uses...

In a two-country reciprocal dumping model, with one country unionized, we analyze how wage setting and firm location are influenced by trade liberalization. We show that trade liberalization can induce FDI, which is at odds with conventional theoretical wisdom and cannot happen in a...

We propose a dynamic general equilibrium model with human capital accumulation to evaluate the economic consequences of compulsory services (such as military draft or social services). Our analysis identifies a so far ignored dynamic cost arising from distortions in time allocation over the...

This paper studies the welfare consequences of a vertical merger that raises rivals costs when downstream competition is à la Cournot between firms with constant asymmetric marginal costs. The main result is that such a vertical merger can nevertheless improve welfare if it involves a...

This paper examines how free-trade agreements and customs unions affect the location of foreign direct investment (FDI) and social welfare, taking into account that governments may adjust taxes and external tariffs to compete for FDI. Conditions are identified under which a free-trade agreement...

In framework of Rochet and Tirole (2011), I allow for partial merchant internalization and study how MIT threshold is related to levels of inter-change fee that maximize various components of social welfare. I find that cost absorption on the side of issuers and merchant heterogeneity each bias...
