Middle-class black consumers and intensity of ethnic identification

This article reports on an empirical study analyzing the differences between black (buppies) and Anglo (yuppies) middle-class consumers responding to advertising featuring celebrity endorsers. Particular attention is given to variability within the black consumer segment by examining intensity of identification and socioeconomic status. Using a laboratory experiment, 160 subjects were drawn from a large metropolitan area. The implications are that while black consumers who have moved up the socioeconomic ladder have similar responses to their Anglo counterparts, they should not necessarily be viewed as having lost strong ethnic identity.

Born-International SMEs: BI-Level Impacts of Resources and Intentions

The Katz and Gartner (1988) model describes four central properties of emerging organizations: resources, intention, exchange, and boundary. While designed as a general model for organizations, the approach has the potential to explain the early lives of "born-international" firms. In this study, boundary is used to define the central sampling frame. Two other properties, resources and intention, are evaluated in terms of their impact on the fourth property: exchange, measured as a firm's export growth and intensity. Given the inherent presence of two levels of analysis in emerging organizations, intention and resources are evaluated at both the individual and the organizational level. A sample (N = 47) of young "born-international" firms in the Indian software industry was studied, using a questionnaire. Results of the analysis are mixed for resources at both the individual and firm level variables. Intention is significant at the individual level but not the firm level. Contrary to other studies, these findings suggest that during the early stages of firm development, owner, not firm, characteristics play a pivotal role in performance, especially exports. The speculation is that this occurs because, in early stages, firms are relatively disorganized relative to the owner.     

Virtual Instant Global Entrepreneurship

International entrepreneurship must be hard, because so few firms attempt it. If true, perhaps it is hard because it requires knowledge about people and places far away. It is hard because it requires mastering processes to handle business across borders. And it is hard because it requires trust in the processes and eventually in the customers elsewhere. These three elements, knowledge, mastery and trust in international business are essential to the success of international entrepreneurship for SMEs.     

Optimal Consumption-Portfolio Policies With Habit Formation1

This is a companion paper to the authors ‘Asset Prices in an Exchange Economy with Habit Formation” in Econometrica which focuses on consumption demand and asset pricing when preferences are habit forming. Here we prove existence of optimal consumption-portfolio policies for (i) utility functions for which the marginal cost of consumption (MCC) interacts with the habit formation process and satisfies a recursive integral equation with forward functional Lipschitz integrand and (ii) utilities for which the MCC is independent of the standard of living and satisfies a recursive integral equation with locally Lipschitz integrand. Result (i) is demonstrated here for the first time. Result (ii) is novel and enables us to consider Cobb-Douglas utilities without placing lower bounds on the system of Arrow-Debreu prices. We also review and extend our earlier results in the linear case; in particular, we provide new insights about the structure of optimal portfolios. Additional new features of the model include the possibility of finite marginal utility of consumption at zero and habit formation mechanisms with stochastic coefficients. an extension to a financial market model with general processes is outlined. A byproduct of the analysis is a set of fixed-point theorems for recursive integral equations with forward functional Lipschitz or locally Lipschitz integrands.     

Endogenous change and the economic theory of regulation

This paper extends the economic theory of regulation to include endogenous regulatory change. It outlines conditions under which endogenously rising deadweight costs of regulation can alter the policy equilibrium, even if those rising costs are fully anticipated. Within this framework, alternative wealth redistribution mechanisms can alter the equilibrium path if they bias interest groups' organization costs asymmetrically. The history of natural gas regulation is broadly consistent with this theory.     

Providers’ affiliation,insurance and collusion

This paper provides a theoretical analysis of the benefits for an insurance company to develop its own network of service providers when insurance fraud is characterized by collusion between policyholders and providers. In a static framework without collusion, exclusive affiliation of providers allows insurance companies to recover some market power and to lessen competition on the insurance market. This entails a decrease in the insured’s welfare. However, exclusive affiliation of providers may entail a positive effect on customers’ surplus when insurers and providers are engaged in a repeated relationship. In particular, while insurers must cooperate to retaliate against a fraudulent provider under non-exclusive affiliation, no cooperation is needed under exclusive affiliation. In that case, an insurer is indeed able to reduce the profit of a malevolent provider by moving to collusion-proof contracts when collusion is detected, and this threat may act as a deterrent for fraudulent activities. This possibility may supplement an inefficient judicial system: it is thus a second-best optimal anti-fraud policy.
