Conditional distributions of earnings,wages and hours for blacks and whites

This paper provides new evidence on the conditional distributions of earnings, wages and hours for white and black males in the University of Michigan's Panel Study of Income Dynamics. Conditional hours and ln wages are approximately normal for both races. Conditional earnings are approximately normal for blacks while earnings are well approximated for whites by the product of normal hours and log-normal wages. The distribution of this product is derived here for the first time. Treating the marginal earnings distribution as the average of the conditional distributions, we use these results to predict poverty and affluence rates in our sample.     

Forecasting foreign exchange rates: an expert judgment approach

Studies have indicated that forecasts by market experts can be more accurate than time series forecasts. This article describes a process for structuring an expert foreign exchange forecast using Saaty's Analytic Hierarchy Process (AHP). The specific example developed is a forecast of the yen/dollar spot exchange rate from the standpoint of a company considering the desirability of arranging for forward exchange cover.     

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.     

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.     

Price,output, and exchange rate movements in the open economy

Since the advent of managed floating it has come to be accepted as a stylized fact that short-run deviations from purchasing power parity are both substantial and persistent. Two explanations of these deviations have been advanced in the literature. One emphasizes the role of changes in non-traded goods prices while the other views deviations from purchasing power parity as being due to sticky goods prices and slow adjustment of goods markets. This paper presents yet a third possible explanation of deviations from purchasing power parity — they may be necessary in order to facilitate the relative price changes that are required to maintain equilibrium in the face of unanticipated shocks. In addition, the issue of exchange rate overshooting is addressed. Whereas the sticky price models view exchange rate overshooting and exchange rate volatility as symptoms of some fundamental disequilibrium, the perspective taken here is that these events are, in principle, compatible with a world in which all markets clear continuously.     

Market structure and competitive conditions in the Arab GCC banking system

This paper investigates the market structure of Arab GCC banking industry during the years of 1993–2002 using the most frequently applied measures of concentration k-bank concentration ratio (CRk) and Herfindahl–Hirschman Index (HHI) and evaluates the monopoly power of banks over the ten years period using the ‘H-statistic’ by Panzar and Rosse. The results show that Kuwait, Saudi Arabia and UAE have moderately concentrated markets and are moving to less concentrated positions. The measures of concentration also show that Qatar, Bahrain and Oman are highly concentrated markets. The Panzar–Rosse H-statistics suggest that banks in Kuwait, Saudi Arabia and the UAE operate under perfect competition; banks in Bahrain and Qatar operate under conditions of monopolistic competition; and we are unable to reject monopolistic competition for the banking market in Oman.     

A research program for establishing the validity of the price-quality relationship

Despite over 30 years of empirical investigations, it remains unclear whether (1) there is an actual positive relationship between price and product quality, and (2) whether buyers perceive a positive relationship between price and product quality. Although there has been a plethora of studies on the relationship, there is little agreement on what we know about the relationship. The paper assesses the current state of knowledge on the relationship and argues for a better conceptual framework for understanding the price-quality relationship. Then the paper outlines a systematic research program for establishing the validity of the relationship, and establishes a set of criteria for evaluating the contribution to knowledge of future research on the price-quality relationship.     

Strengthening the weak link in strategic executive development: Integrating individual development and global business strategy

The global business environment of the 1990s provides both challenge and opportunity to human resource development to become an integral player in helping implement business strategy. The results of two best practice studies suggest that some leading firms such as 3M and Motorola are doing just that. At these companies current strategic business issues are the drivers of flexible and opportunistic executive development activities. Naturally occurring on-the-job experiences are consciously utilized in such a way that helping executives to develop becomes an integral part of conducting business. The implications of linking executive development to business strategy for practice and for future research are discussed. © 1995 by John Wiley & Sons, Inc.
