Job Characteristics and Labor Market Discrimination in Promotions

We extend promotion signaling theory to generate new testable implications concerning racial differences in promotions. In our model, promotions signal worker ability. When tasks differ substantially across job levels, the opportunity cost of not promoting qualified non‐whites/non‐Asians is large, so employers are less likely to inefficiently withhold their promotions. Thus, given prepromotion performance, the extent to which non‐whites/non‐Asians have lower promotion probabilities decreases when tasks vary more across levels. Racial differences in wage increases at promotion diminish when tasks vary more across levels. Evidence from a single firm's personnel records supports the model's predictions concerning promotion probabilities.     

Firm ownership and internal labour practices in a transition economy

One feature common to many post‐socialist transition economies is a relatively compressed wage structure in the state‐owned sector. We conjecture that this compressed wage structure creates weak incentives for work effort and worker skill acquisition and thus presents adverse consequences for the entire transition economy if a substantial portion of the labour force works in the state sector. We explore firm wage incentives and worker training, as well as other labour practices and outcomes, in a transition setting with matched firm and worker data collected in one of the largest provinces of Vietnam – Ho Chi Minh City. The Vietnamese state sector exhibits a compressed wage distribution in relation to privately owned firms with foreign ownership. State wage practices stress tenure over worker productivity and their wage policies result in flatter wage–experience profiles and lower returns to education. The state work force is in greater need of formal training, a need that is in part met through direct government financing. In spite of the opportunities for government financed training and at least partly due to inefficient worker incentives, state firms, by certain measures, exhibit lower levels of labour productivity. The private sector comparison group to state firms for all of these findings is foreign owned firms. The internal labour practices of foreign firms are more consistent with a view of profit‐maximizing firms operating with no political constraints. This is not the case for Vietnamese de novo private firms that exhibit much more idiosyncratic behaviour and whose labour practices are often indistinguishable from state firms. The exact reasons for this remain a topic of on‐going research yet we conjecture that various private sector constraints, including limited access to formal capital, play an important role.     

The effects of network groups on minority employee turnover intentions

Companies in the United States are concerned with retaining minority employees to maintain or increase the diversity of their workforce. Here we assess the value of one approach companies have used to retain minority employees: “network” groups. Based on data obtained from a large company with extensive network groups, this study compares the turnover intentions of minority employees who have joined one of the company's network groups to those who have not joined one of the company's network groups. The data show that employee network groups can be useful in helping companies retain managerial‐level minority employees. Extensive recommendations are provided to help organizations maximize the effectiveness of network groups. © 2002 Wiley Periodicals, Inc.

A three-way corporate partnership for specialty hospitals

Ultimately, the burden of escalating health care costs will be shared by all. A coalition of hospitals, suppliers, and group purchasing organizations possesses the power to communicate with each other as well as to ensure viability in the 21st century. Creative contracting will hopefully become the wave of the future in the health care industry.     

Searching for the sunk cost fallacy

We seek to isolate in the laboratory factors that encourage and discourage the sunk cost fallacy. Subjects play a computer game in which they decide whether to keep digging for treasure on an island or to sink a cost (which will turn out to be either high or low) to move to another island. The research hypothesis is that subjects will stay longer on islands that were more costly to find. Eleven treatment variables are considered, e.g. alternative visual displays, whether the treasure value of an island is shown on arrival or discovered by trial and error, and alternative parameters for sunk costs. The data reveal a surprisingly small sunk cost effect that is generally insensitive to the proposed psychological drivers.

Low information nash equilibria for oligopolistic markets

This paper deals with an infinite horizon n firm oligopoly in which firms are assumed to have incomplete information about one another's actions and profit functions. An equilibrium concept is defined that is similar to the Nash non-cooperative equilibrium, but is suitable for the information assumptions of the model. The equilibrium uses a type of bounded rationality which makes firms' computations relatively easy. This is due to an implicit assumption that computation is costly and a Bayesian approach is prohibitively costly. This low information Nash equilibrium is proved to exist, and, in addition, an adaptive expectations decision process is described which, if followed by all firms, leads to the low information Nash equilibrium.     

Separating the Hawks from the Doves: Evidence from continuous time laboratory games

Human players in our laboratory experiment received flow payoffs over 120 seconds each period from a standard Hawk–Dove bimatrix game played in continuous time. Play converged closely to the symmetric mixed Nash equilibrium under a one-population matching protocol. When the same players were matched in a two-population protocol with the same bimatrix, they showed clear movement towards an asymmetric (and very inequitable) pure Nash equilibrium of the game. These findings support distinctive predictions of evolutionary game theory.     

A Monetarist View

Friedman examines the quantity theory of money and the recent application of monetary policy in Japan, the United Kingdom, and the United States. In all three countries, the reduction of monetary growth has reduced inflation. In the United States, in 1983, the renewed expansion of the money supply raises the distinct possibility that inflation will resume in 1984 or 1985, according to the author.
