摘要：This paper focuses on the role of an initial public offering (IPO) in maximizing the proceeds an initial owner obtains in selling his company. In deciding whether to undertake an IPO, and what fraction of ownership to retain, the initial owner must balance two factors. By selling to dispersed shareholders, he maximizes his proceeds from the sale of cash flow rights. However, by directly bargaining with a potential buyer, he maximizes his proceeds from the sale of control rights. Whether a comp...

摘要：We demonstrate how to estimate a model of oligopoly pricing when products are multi-dimensionally differentiated. We provide an empirical counterpart to recent theoretical work on product differentiation. Using specifications informed by economic theory, we estimate price-cost margins for products differentiated in many dimensions.

摘要：We investigate the structure of competitive equilibria in an exchange economy parametrized by (i) endowments and (ii) restrictions on market participation. For arbitrary regular endowments, if few consumers are restricted, there are no sunspot equilibria. If endowments are allowed to vary, while restrictions on market participation are fixed, there is a generic set of preferences such that sunspot equilibria exist for a non-empty subset of endowments. Our analysis extends to the general case o...

摘要：We introduce a new model for time-varying conditional variances as the most general quadratic version possible within the ARCH class. Hence, it encompasses all the existing restricted quadratic variance functions. Its properties are very similar to those of GARCH models, but avoids some of their criticisms. In univariate applications to daily U.S. and monthly U.K. stock market returns, QARCH adequately represents volatility and risk premia. QARCH is easy to incorporate in multivariate models t...

摘要：The aggregate rate of RandD in a competitive economy is compared with the optimal rate. The optimal rate of RandD is shown to be the same for all preferences in a broad family, while the competitive rate is sensitive to the form of substitutability among products and so can vary dramatically within a family. The second-best level of RandD is shown to be also common within a family and equal to the optimal rate. Numerical examples suggest that diminishing returns in the innovation technology is...
