The "revolving door" phenomenon has become very common in most industrialised countries, and is leading to conflicts of interest as well as economic distortions. The purpose of this paper is to develop an indicator of the distortionary effects of the revolving door - The Revolving Door Indicator...

This paper examines bidding behavior in a setting where post-bid-letting project modifications occur. These modifications change both the costs and payouts to the winning contractor, making the contract incomplete. Recent empirical research shows that bidders incorporate the likelihood of such...

Can an increasing importance of intangible capital explain increases in markups and profits? I use a heterogeneous firm model to show how intangible capital, characterized by fixed costs and uncertainty, is related to markups and profits at the industry level. The scalability and uncertainty...

Improving a company's bargaining position is often cited as a chief motivation to vertically integrate with suppliers. This paper expands on that view in building a new theory of vertical integration. In my model firms integrate to gain bargaining power against other suppliers in the production...

The traditional argument that shorter product cycles favor trade secret over patenting is reviewed. A game theoretic model provides an argument that shorter product cycles can induce firms to file more patent applications. The firms may be trapped in a prisoners' dilemma where all firms would...

This study examines whether staged project management is beneficial or harmful for making product innovations. Using a unique firm survey for Japan, we find that firms that employed staged project management had a higher likelihood of introducing new products to the market. Additional...

We estimate the determinants of various types of product innovation. Knowledge spillovers from rivals have a positive impact on incremental innovations. This impact is largely independent of the participation in R&D cooperations. Spillovers exert no such independent influence on drastic...

This paper investigates how different damage rules in patent infringement cases shape competition when intellectual property rights are probabilistic. I develop a simple model of oligopolistic competition to compare two main liability doctrines that have been used in the US to assess...

This paper provides an empirical analysis of the effects of new product versus process innovations on export propensity at the firm level. Product innovation is a key factor for successful market entry in models of creative destruction and Schumpeterian growth. Process innovation helps securing...

This paper develops a fully-endogenous, variety-expansion growth model with firm-specific quality heterogeneity, limit pricing, and an endogenous distribution of markups.Trade induces only firms with high-quality products to export, whereas firms with low-quality products serve only the domestic...
