The Effect of Enterprise Systems Implementation on the Firm Information Environment

This study uses an archival research design to assess the impact of enterprise systems on a firm's internal information environment as reflected in the production of management earnings forecasts. Specifically, the authors hypothesize that, if enterprise systems improve management's access to decision‐relevant internal information, higher quality management earnings forecasts should ensue. Consistent with disclosure theory and the purported technical characteristics of enterprise systems, the authors find a positive association between enterprise system implementations and subsequent increases in the likelihood of management forecast issuance and the accuracy of the forecasts. Additional robustness tests support the argument that improvements in management forecasts are due to improvements in the firm's internal information environment rather than to enhancements in management's ability to manage earnings. Beyond accumulating financial reporting information, the authors note that such systems provide management with information to make day‐to‐day operational decisions. Moreover, the paper provides a basis for considering management forecast qualities as a measurable proxy for improvements in the firm's internal information environment that result from information technology investments.     

Reciprocity, Trust, and Payoff Privacy in Extensive Form Bargaining

We report decision making in two-person extensive form game trees, using six treatments that vary matching protocol, payoffs, and payoff information. Our objective is to examine game theoretic hypotheses of decision making based on dominance and backward induction in comparison with the culturally or biologically derived hypothesis that reciprocity supports more cooperation than predicted by game theory. We find strong support for cooperation under complete information, even in single-play treatments and in games of trust, unreinforced by the prospect of punishment for defection from reciprocity. Only under private information do we observe strong support for noncooperative game theory.Journal of Economic LiteratureClassification Numbers: C78, C92.     

Scale Externalities in Korea

This paper estimates the nature and magnitude of scale externalities in a developing country, Korea, in the period 1983–1993. This is a period of rapid industry deconcentration from Seoul to other metro areas, providing a context where externalities are measured when local scale magnitudes are changing dramatically. The data allow us to examine the emerging degree of national industrial concentration in different industries, as related to their scale externality magnitudes. We also examine whether individual industries agglomerate in cities which have a comparative advantage for that industry.     

A new business venture

This paper describes the action which was taken by the Pharmaceuticals Division of ICI Limited to move into a New Business Venture, the experiences so far and some of the lessons learned which either have confirmed or contradicted the original ideas.
The venture is into the business area of Medical Aids. The first steps were taken by the Division just over three years ago.
