Event-Study Methodology Under Conditions Of Event-Induced Variance, Ekkehart Boehmer, Jim Masumeci, Annette B. Poulsen Dec 1991

Event-Study Methodology Under Conditions Of Event-Induced Variance, Ekkehart Boehmer, Jim Masumeci, Annette B. Poulsen

Research Collection Lee Kong Chian School Of Business

Many authors have identified the hazards of ignoring event-induced variance in event studies. To determine the practical extent of the problem, we simulate an event with stochastic effects. We find that when an event causes even minor increases in variance, the most commonly-used methods reject the null hypothesis of zero average abnormal return too frequently when it is true, although they are reasonably powerful when it is false. We demonstrate that a simple adjustment to the cross-sectional techniques produces appropriate rejection rates when the null is true and equally powerful tests when it is false.

The Manufacturing Contribution To Innovation, Arnoud De Meyer Oct 1991

The Manufacturing Contribution To Innovation, Arnoud De Meyer

Research Collection Lee Kong Chian School Of Business

The description of the contribution of manufacturing to the innovation process is often limited to the task of providing the necessary information to enable the development function to create a design which is easy to manufacture, and to be instrumental in the fast ramp-up of the production process. Though these are important tasks, it is argued in this paper that there is a third aspect of manufacturing’s contribution to innovation, namely the creation of a manufacturing system which is favorable to product innovation. This goes far beyond the design of an appropriate production process, but requires the creation of a …

Individual Differences In Response To Consumer Promotions, Gwen Ortmeyer, James M. Lattin, David B. Montgomery Sep 1991

Individual Differences In Response To Consumer Promotions, Gwen Ortmeyer, James M. Lattin, David B. Montgomery

Research Collection Lee Kong Chian School Of Business

This research hypothesizes important individual differences in response to promotions and tests for them using a cross-sectional multinomial logit choice model. Our hypotheses suggest interactions between individual brand preference and the effects of current promotion and past promotional purchase. To test for these interactions, we introduce a new method of measuring brand preference from past purchase data. The new method seeks to incorporate competitive purchase conditions as modifiers to observed brand purchase behavior in estimating consumer brand preference. We account for heterogeneity in the cross-sectional model by using two measures of loyalty: one to capture differences across individuals and one …

Reuse And Productivity In Integrated Computer-Aided Software Engineering: An Empirical Study, Rajiv D. Banker, Robert J. Kauffman Sep 1991

Reuse And Productivity In Integrated Computer-Aided Software Engineering: An Empirical Study, Rajiv D. Banker, Robert J. Kauffman

Research Collection School Of Computing and Information Systems

Growing competition in the investment banking industry has given rise to increasing demand for high functionality software applications that can be developed in a short period of time. Yet delivering such applications creates a bottleneck in software development activities. This dilemma can be addressed when firms shift to development methods that emphasize software reusability. This article examines the productivity implications of object and repository-based integrated computer-aided software engineering (ICASE) software development in the context of a major investment bank's information systems strategy. The strategy emphasizes software reusability. Our empirical results, based on data from 20 projects that delivered software for …

Technology Exports From A Small, Very Open Nic: The Case Of Singapore, Eng Fong Pang, Hal Hill May 1991

Technology Exports From A Small, Very Open Nic: The Case Of Singapore, Eng Fong Pang, Hal Hill

Research Collection Lee Kong Chian School Of Business

This paper examines the nature, composition and determinants of Singapore's early stage technology exports. The pattern of these exports reflects the quite unique mix of policy and institutional features in Singapore's environment - remarkably high growth, very open economy, rapid structural change, particularly intense economic relations with neighboring Southeast Asian nations, and a pervasive and paternalistic state role. The bases of Singapore's comparative advantage in these service exports are identified, and some general implications from its experience are analyzed.

Interpreting And Responding To Strategic Issues: The Impact Of National Culture, Susan C. Schneider, Arnoud De Meyer May 1991

Interpreting And Responding To Strategic Issues: The Impact Of National Culture, Susan C. Schneider, Arnoud De Meyer

Research Collection Lee Kong Chian School Of Business

Perceptions of environmental uncertainty and organizational control influence strategic behavior. As national culture influences these perceptions we expect to find cultural differences in interpretation and response to strategic issues. Given a case describing an issue concerning deregulation of the U.S. banking industry, managers completed questionnaires rating interpretations and responses to that issue. National culture was found to influence interpretation and responses. In particular, Latin European managers when compared with other managers were more likely to interpret the issue as a crisis and as a threat. Latin Europeans were also more likely to recommend proactive behavior. This study indicates that different …
