The effect of interstate highway on driving times and regional shopping center drawing power

Previous studies of the driving times of shopping center patrons have not examined the effect of limited access highways. This study analyzed the impact of interstate highways on the driving times of 204 shoppers at three medium-sized regional shopping centers. Those shoppers indicating usage of interstate highways to reach their shopping destinations were significantly more likely to incur travel times greater than fifteen and twenty minutes than those not using the available interstate roads. In predicting the drawing power of these shopping centers, factors besides mass were found to be useful. These include square footage of shopping goods, stores, and number of parking places.

Old flames never die – the role of binding social ties for corporate entrepreneurship in family firms

This paper investigates the role of social ties and family embeddedness for corporate entrepreneurship in family firms. Family firms are mostly characterized by close and often inseparable ties between the dominant family coalition and the firm and offer specific resources within a context of both rational as well as non-rational factors that influence entrepreneurial strategies. We empirically test (n =?181) the relationship between binding social ties and innovation, strategic renewal, and corporate venturing. Our findings indicate a strong significance for networks and close and stable relationships both to inside the firm and the outside in decision making for corporate venturing and innovation. In contrast, the results for strategic renewal show no relevance of strong social ties. We link up with the debate on the role of owners as an important stakeholder group.

The subjective expected utility hypothesis and revealed preference

Summary A choice behavior of a decision maker is said to satisfy the subjective expected utility hypothesis if there exist a utility and a subjective probability such that a decision maker chooses acts with the highest expected utility. We present a revealed preference characterization of choice behavior that is consistent with the subjective expected utility hypothesis. Our result applies to any state space and compact sets of prizes and observations (either finite or infinite).     

Information flow,job search,and migration

"In this paper, an individual model of rural-urban migration is studied, emphasizing the effects of information flow and urban wage dispersion. Migration is viewed in the context of a lifetime program of job search. It is shown that migration can occur even when the mean urban wage is no larger than the rural income flow.... Both the shape and spread of the urban wage dispersion are shown to affect migration behavior significantly." The geographical focus is on developing countries.
