A typology of social entrepreneurs: Motives, search processes and ethical challenges

Social entrepreneurship has been the subject of considerable interest in the literature. This stems from its importance in addressing social problems and enriching communities and societies. In this article, we define social entrepreneurship; discuss its contributions to creating social wealth; offer a typology of entrepreneurs' search processes that lead to the discovery of opportunities for creating social ventures; and articulate the major ethical concerns social entrepreneurs might encounter. We conclude by outlining implications for entrepreneurs and advancing an agenda for future research, especially the ethics of social entrepreneurship.     

Generous actors,selfish actions: markets with other-regarding preferences

This paper points out that classical competitive outcomes arise in two different market environments even if agents have non-classical preferences. Consumers with separable, other-regarding preferences behave as if they have classical preferences in competitive equilibrium. These outcomes need not be efficient, but under plausible conditions will be efficient following a redistribution of income. In simple double-auction environments competitive outcomes arise under a wide range of assumptions on preferences even without assuming separability. I discuss the importance of the domain of definition of preferences and how the preferences present in the economy influence the performance of the trading institution.

What does tax aggressiveness signal? Evidence from stock price reactions to news about tax shelter involvement

We study the stock price reaction to news about corporate tax aggressiveness. We find that, on average, a company's stock price declines when there is news about its involvement in tax shelters. We find some limited evidence for cross-sectional variation in the reaction. For example, the reaction is more negative for firms in the retail sector, suggesting that part of the reaction may be a consumer/taxpayer backlash. In addition, the reaction is less negative for firms that are viewed to be generally less tax aggressive, as proxied by the firm's cash effective tax rate. We interpret this as being consistent with the market reacting positively to evidence that a firm is trying to reduce taxes when their financial reports would lead one to believe the firm is not tax aggressive.     

More than meets the eye: videography and production of desire in semiocapitalism

ABSTRACT

In the light of the recent proliferation of interest in videographic methods in marketing and consumer research, we wish to make a call for thinking critically about the medium. In this article, we challenge traditional means of semiotic analysis and consider contexts outside aesthetic symbolism that take into account wider agencements of videographic inquiry. We sensitise thinking about videographic production to include a broad scope of influence beyond production and spectatorship. By positing a mode of desiring relationalities in ‘semiocapitalist’ markets, and through the illustrative example of pop-music videos, we show how videography not only produces symbols, but also has the tendency to discipline the viewer into particular subjective positions. We hope to add to the conceptual toolkit of aspiring video scholars and encourage them to be increasingly critical and reflexive about their potential impact.     

Manufacturer Mergers and Product Variety in Vertically Related Markets

We study the incentives of final product manufacturers to introduce new products into the market and the impact of a manufacturer merger on them. We show that when manufacturers distribute their products through multi-product retailers, a manufacturer merger, although it leads to an increase in the wholesale prices, it can enhance product variety. The merger induced product variety enhancement though arises only when vertical relations are present: when manufacturers sell directly their products to consumers, a merger never results in more product variety. Still, both with or without vertical relations, a manufacturer merger hurts consumers and decreases welfare.     

INTERVALLING EFFECTS IN HONG KONG STOCKS

This paper investigates the intervalling-thinness effect in the Hong Kong stock market and compares the results with previous studies of United States and French data. The approach follows the three pass technique of Cohen, Hawawini, Maier, Schwartz, and Whitcomb. Various functional forms of an intervalling bias decay function are analyzed, both in the aggregate and for individual stocks. Careful modeling of the flattening of the beta profile at a finite interval value leads to robust estimated asymptotic betas.
