Applied general-equilibrium (AGE) models have often made compromises to circumvent difficult modeling problems. One of these is avoiding endogenous zeros, ruling out important questions. Traditional perfect competition models: when do technologies or trade links switch from active to inactive or...

We argue in this paper that retailers can strategically position store brands in product space to strengthen their bargaining position when negotiating supply terms with manufacturers of national brands. Using a bargaining framework we model a retailer's decision whether to carry an additional...

This paper develops a model of informal procurement within Japanese keiretsu so as to consider effects on intermediate-good imports, such as auto parts. Parts-suppliers make relationship-specific investments that benefit the auto-maker and prices are determined by bargaining after investment has...

More advanced technologies demand higher degrees of specialization - and longer chains of production connecting raw inputs to final outputs. Longer production chains are subject to a "weakest link" effect: they are more fragile and more prone to failure. Optimal chain length is determined by the...

In a search model, prospects encounter salespeople who can try to persuade them. Persuasive messages can increase the utility of buying or increase the cost of not buying. The latter reduces welfare. Equilibria where only some salespeople make a persuasive effort often exist. Salespeople vary in...

This paper considers the implications of relationship-specific investment within keiretsu for policies aimed at opening the Japanese market for intermediate goods, such as auto parts. Both VIEs applied to parts and VERs restricting Japanese exports of autos cause the keiretsu to import a wider...

We examine how the U.S. Federal Government governs R&D contracts with private-sector firms. The government chooses between two contractual forms: grants and cooperative agreements. The latter provides the government substantially greater discretion over, and monitoring of, project progress....

This paper examines the importance of buyer-supplier relationships, geography and the structure of the production network in firm performance. We develop a simple model where firms can outsource tasks and search for suppliers in different locations. Low search and outsourcing costs lead firms to...

We analyze a model where investors use a credit rating to decide whether to finance a firm. The rating quality depends on unobservable effort exerted by a credit rating agency (CRA). We study optimal compensation schemes for the CRA when a planner, the firm, or investors order the rating. Rating...
