Differentiated Products Demand Systems from a Combination of Micro and Macro Data: The New Car Market

Abstract: In this paper, we exploit new sources of cross-sectional data to estimate a detailed product-level demand system for new passenger vehicles. We use four data sources: on the characteristics of products, on the attributes of the U.S. population of households, on the match between the first and second vehicle choices of the household, and on the match between households attributes and first choice vehicles. We show that these data solve some, but not all, of the traditional problems in estimating differentiated products demand systems and indicate which data sources are important for which problem. The data is rich enough to reveal a rather complex substitution pattern, requiring a quite general modeling framework. Together the data and model make a detailed analysis of industry demand possible.

The Effect of Information on Product Quality: Evidence from Restaurant Hygiene Grade Cards

Abstract: This study examines the effect of an increase in product quality information to consumers on firms' choices of product quality. In 1998, Los Angeles County introduced hygiene quality grade cards to be displayed in restaurant windows. We show that the grade cards cause (i) restaurant health inspection scores to increase, (ii) consumer demand to become sensitive to changes in restaurants' hygiene quality, and (iii) the number of foodborne illness hospitalizations to decrease. These results imply the grade cards cause restaurants to make hygiene quality improvements. The regulatory change also provides an opportunity to separately analyze the effects of mandatory disclosure of grade cards and voluntary disclosure of grade cards, because in some cities the posting of grade cards is at restaurants' discretion. We find that the effects from voluntary disclosure are statistically different, but not economically different, from mandatory disclosure.

Integration vs. Outsourcing in Industry Equilibrium

Abstract: We develop an equilibrium model of industrial structure in which the organization of firms is endogenous. Differentiated consumer products can be produced either by vertically integrated firms or by pairs of specialized companies. Production of each variety of consumer good requires a unique, specialized component. Vertically integrated firms can manufacture the components they need in the quantity and type that maximizes profits, but they face a relatively high cost due to diseconomies of scope. Specialized firms can produce at lower cost, but outsourcing imposes costs due to search frictions and imperfect contracting. We study the equilibrium mode of organization when inputs are fully or partially specialized. We consider how the degree of competition in the industry, the nature of the search technology, the division of bargaining strength between intermediate and final producers, and the sensitivity of manufacturing costs to input characteristics affect the equilibrium organizational form.

A Simple Theory of Multinational Corporations and Trade with a Trade-Off between Proximity and Concentration

Abstract: This paper develops a two-sector, two-country model, where firms in a differentiated products sector choose between exporting and multinational expansion as alternative modes of foreign market penetration, based on a trade-off between proximity and concentration advantages. The differentiated sector is characterized by multi-stage production, with increasing returns at the corporate level associated with some activity such as R&D, scale economies at the plant level, and a variable transport cost that rises with distance. A pure multinational equilibrium, where two-way horizontal expansion across borders completely supplants two-way trade in differentiated products, is possible even in the absence of factor proportion differences. It is more likely the greater are transport costs relative to fixed plant costs, and the greater are increasing returns at the corporate level relative to the plant level. The model also establishes conditions for a mixed equilibrium, in which national and multinational firms coexist.

Capital Account Liberalization: Theory, Evidence, and Speculation

Abstract: Writings on the macroeconomic impact of capital account liberalization find few, if any, robust effects of liberalization on real variables. In contrast to the prevailing wisdom, I argue that the textbook theory of liberalization holds up quite well to a critical reading of this literature. The lion's share of papers that find no effect of liberalization on real variables tell us nothing about the empirical validity of the theory, because they do not really test it. This paper explains why it is that most studies do not really address the theory they set out to test. It also discusses what is necessary to test the theory and examines papers that have done so. Studies that actually test the theory show that liberalization has significant effects on the cost of capital, investment, and economic growth.
