Supervisor Support for the Permanent Replacement of Economic Strikers

Sixty-one supervisors were surveyed to examine the importance of organization commitment, union approval, and quality of union-management relationship in explaining supervisor support for hiring permanent replacements in short and long strike situations. Organization commitment and union approval exhibited a unique negative relationship with support for hiring replacements in a short strike, and union approval exhibited a unique negative relationship with support for hiring replacements in a long strike situation.     

Explaining the Cross‐Section of Stock Returns in Japan: Factors or Characteristics?

Japanese stock returns are even more closely related to their book-to-market ratios than are their U.S. counterparts, and thus provide a good setting for testing whether the return premia associated with these characteristics arise because the characteristics are proxies for covariance with priced factors. Our tests, which replicate the Daniel and Titman (1997) tests on a Japanese sample, reject the Fama and French (1993) three-factor model, but fail to reject the characteristic model.     

The information content of the exchange rate and the stability of real output under alternative exchange-rate regimes

When the exchange rate is flexible, and thus responds to market forces, it provides agents with useful information, while when it is fixed (by a feedback rule) it does not. The implications of this asymmetry for the stability of real output under the two regimes is discussed. It is shown that whenever shocks are predominantly of one variety, or when domestic monetary shocks accompanied by one real shock, a flexible exchange rate does a better job of stabilizing real output than does a fixed exchange rate. These results undermine arguments favoring fixed exchange rates because they ‘discipline’ monetary policy. In addition, it is demonstrated that managed floating rules and exchange rate feedback rules are irrelevant for the distribution of real output.     

Rafting the River: A Risk Management Expert System for Dynamic Problem Solving

Commercial project management systems focus on preproject planning and after-the-fact documentation, but not on the dynamic problem solving required in day-to-day project management. Yet the need for risk-oriented management is clear. To understand and control project risks, managers must be able to identify problems as they occur, immediately assess their downstream impacts, and plan a course of action. The Advanced Risk Management System (ARMS) is a prototype system built to address the issues of identifying, analyzing, prioritizing, monitoring, and controlling project risk. ARMS uses expert systems, data base management, and hypermedia technologies to capture and classify project schedule problems, to determine their semantic impacts to future activities, and to alert appropriate project personnel in advance of problem occurrence.
