Analysis of covariance techniques have been developed primarily for normally distributed errors. We give solutions when the errors have non-normal distributions. We show that our solutions are efficient and robust. We provide a real-life example. Copyright (c) 2009 The Authors. Journal...

The time/cost trade-off models in project management aim to reduce the project completion time by putting extra resources on activity durations. The budget problem in discrete time/cost trade-off scheduling selects a time/cost mode for each activity so as to minimize the project completion time...

The primary goal of this study was to propose an algorithm using mathematical programming to detect earnings management practices. In order to evaluate the ability of this proposed algorithm, the traditional statistical models are used as a benchmark <TOGGLE>vis-à-vis</TOGGLE> their time series counterparts. As...</toggle>

This paper derives a necessary and sufficient condition under which increased health care productivity must lead to decreased (increased) demand for health care as long as the demand for health care is inelastic (elastic). It is shown that this condition identifies a class of health production...

In this article, spillover effects of foreign direct investments on Turkish manufacturing industry have been examined by five single equation econometric models. All models are constructed in line with the recent spillover models both for developed and developing economies. The first two models...

This paper examines price clustering on the Tokyo Stock Exchange (TSE). Regardless of tick and lot size, prices ending in zero and five are the most popular. The TSE has no market makers or direct negotiation between traders; therefore, clustering is not explained by collusion or negotiation....

We examine the effect of agency conflicts on debt financing and show that managerial ownership and its interaction with takeover defenses affect these decisions. We find that (1) the relation between leverage and takeover defenses becomes insignificant when we control for the interaction of...
