This paper studies vertical R&D spillovers between upstream and downstream firms. The model incorporates two vertically related industries, with horizontal spillovers within each industry and vertical spillovers between the two industries. Four types of R&D cooperation are studied : no...

This paper studies the decision of firms to expense or capitalize R&D expenditures. The firm has an incentive to mismatch the benefits and costs of R&D, expensing a larger portion of R&D when the benefits occur in the long-run and capitalizing a larger portion when the benefits occur in the...

This paper analyzes mergers involving several leaders and followers in Stackelberg models, with the merged entity acting as a leader. Adding a follower to a merger increases its profitability or reduces its losses. A merger between one leader and any number of followers is always profitable....

This paper introduces the time dimension into the precompetitive R&D model, where both demand and spillovers vary over time. The effect of cooperation on R&D depends on a weighted function of spillovers, with the weights being a function of demand levels. The bulk of the incentives for...

This paper introduces a new type of R&D subsidy, which is conditional on the success of the R&D project. In a three-stage model, the government chooses a subsidy(ies), a monopolist chooses R&D effort which determines the size or the probability of success of the R&D project, and the firm chooses...

This article reviews the literature on the effects of income taxes on married women's labour supply. Taxes, as is well known, introduce nonlinearities and nonconvexities in the budget set. The basic model has benefited from many extensions: cases in point are hours restrictions, intertemporal...

The paper analyzes the profitability of R&D cooperation under asymmetric spillovers. It is shown that a firm prefers R&D competition to RJV cartelization when its own spillover rate is low and the spillover rate of its competitor is high. While it prefers R&D cartelization to RJV cartelization...

The model studies information sharing and the stability of cooperation in cost reducing Research Joint Ventures (RJVs). In a three-stage game- theoretic framework, firms decide on participation in a RJV, information sharing along with R&D expenditures, and output. An important feature of the...
