Information acquisition and provision in school choice: a theoretical investigation

When participating in school choice, students may incur information acquisition costs to learn about school quality. This paper investigates how two popular school choice mechanisms, the (Boston) Immediate Acceptance and the Deferred Acceptance, incentivize students’ information acquisition. Specifically, we show that only the Immediate Acceptance mechanism incentivizes students to learn their own cardinal and others’ preferences. We demonstrate that information acquisition costs affect the efficiency of each mechanism and the welfare ranking between the two. In the case where everyone has the same ordinal preferences, we evaluate the welfare effects of various information provision policies by education authorities.

Competition, Product Innovation and Licensing

This paper compares market profit and social welfare levels between differentiated Bertrand and Cournot duopoly. We start with a basic model in which a firm with a production technology can license its new technology to a potential rival who can use the technology to produce a differentiated product and compete with the incumbent firm. It is found that for any given technology level, Bertrand competition is necessarily more profitable but less socially desirable, due to its higher royalty rate. By contrast, if the licensee firm is an incumbent firm, the results hold if the technology level is high. Furthermore, if we assume the licensor firm can engage in product innovation and choose its optimal technology endogenously and the R&D efficiency is high (low), the welfare ranking is reversed (still holds).

PATENT LENGTH AND PRICE REGULATION IN AN R&D GROWTH MODEL WITH MONOPOLISTIC COMPETITION

This paper considers the effects of patent length and price regulation in an R&D growth model with variety expansion. Innovation requires lower bounds on patent length and price. Increasing patent duration promotes growth; increasing the cap on the price of patented products promotes growth below the monopoly-pricing level. Each policy instrument can raise welfare unless excessively used, and their welfare ranking depends on parameterizations. It is desirable, on welfare grounds, to limit patent protection along both dimensions, namely by limiting patent length and capping the price of patented products. Such limits raise welfare despite reducing the growth rate.
