A commonly used approach in long-run event-studies is the calendar time portfolio (CTP) approach developed by Jaffe (1974) and Mandelker (1974) and advocated by Fama (1998). For each calendar month we compute the return of an equally-weighted portfolio of companies that unionized in the last T months, where T is either 18 or 24 in our study. The return of this “unionization portfolio” is denote...

Theorists have suggested that oppressions based on gender and sexual orientation are inherently linked. The present study aims to operationalize and test this proposition, by modeling relationships between sexual harassment and heterosexist harassment. Based on prior research in organizational and feminist psychology, we hypothesized a three-factor model of workplace harassment, comprising sexu...

The main objective of this paper is to discuss alternative methods for testing the Fama-French (FF) three-factor asset pricing model. The properties of the selected methods are compared through a simulation study. The main stress is put on the behaviour of the selected methods for small samples. The parameters used in the simulation study are obtained on the basis of real data coming from the P...

The advent of University portals [1] accelerated a phenomenon that has been observed for a long time, notably the progressive replacement of locally-deployed applications (in entities, for instance) with centralized applications that permit a software development geared to and around a specific institution's Information System (IS). This transformation, which has already occurred for services (...

This paper describes lessons from running software development projects across three globally distributed educational institutions. What was innovative about this study was that two of the institutions were located in service providing countries, conventional onshore/offshore roles were reversed, and students were exposed to the realities of global supply chain management. Three teams of US stu...
