We present a North-South model of international trade in which differentiated products are developed in the North. Sectors are populated by final-good producers who differ in productivity levels. Based on productivity and sectoral characteristics, firms decide whether to integrate into the...

Depending on the definition of the tax base, the statutory corporate tax rate implies rather different measures of effective average and marginal tax rates. This paper develops a model of a monopolistically competitive industry with extensive and intensive business investment and shows how these...

This paper develops an industry equilibrium model of vertical integration under contractual imperfections with specific input suppliers and external investors. I assume that vertical integration economizes on the needs for contracts with specific input suppliers at the cost of higher financial...

We study the optimal allocation of screening tasks between two agents (incumbent vs. outsider or senior vs. junior) competing for one job. First, we characterize the inefficiencies from the principal's viewpoint of delegating the selection of the screening procedure to the incumbent. In general,...

Miscoordination of buyers might prevent entry in an industry with an incumbent and a more efficient potential entrant. Buyers' power therefore favours entry by eliminating coordination problems. We also identify a mechanism which facilitates entry: if the potential entrant could credibly offer...

We describe new ideas as incomplete concepts for which the innovator needs feedback from agents with complementary skills. Once shared, ideas may be stolen. We compare how different contractual environments support invention and implementation. Markets, as open exchange systems, are good for...

This Paper presents a macroeconomic model where firms may endogenously outsource part of their production process. We start from the premise that adaptation to uncertainty cannot be contracted upon in the worker - employer relationship. Outsourcing decisions then balance flexibility gains...

We analyse the interaction of asymmetric industries in international vertically related markets. Each downstream firm bargains efficiently with its domestic supplier in a first stage and with the foreign supplier in a second stage. The asymmetry in upstream costs leads to inter-industry trade....

This paper investigates the interaction of firms' financial structure and their competitive behaviour on oligopolistic product markets. We consider risk-averse entrepreneurs who produce with uncertain production costs. To reduce their exposure to risk they can sell stocks to risk-neutral...

It is well known that comparative performance information (CPI) can enhance efficiency in static principal-agent relationships by improving the trade-off between insurance and incentives in the design of explicit contracts. In dynamic settings, however, there may be implicit as well as explicit...
