Abstract This study tested the theory that the characteristics of British chief executives would be different from that of the subordinate top management team from which they emanated. The study focused upon variations in experiences over three sets of variables: corporate influences; e.g. tenure, mobility, functional experience, international exposure; domestic influences; e.g. education, family influence; and their self‐concept; e.g. aspiration levels, executive success traits. Substantial differences emerged between the two groups across all sets of variables, particularly within the corporate category.

Abstract This study examines the impact of diversification strategy on risk and return in diversified firms. Following an assessment of previous research on strategic risk, relationships between risk, return, and diversification strategy are hypothesized. Regression analysis shows that differences in risk‐return performance among diversified firms are more closely associated with structural factors associated with markets and businesses than with the particular diversification strategy chosen. Returns also influence the choice of diversification strategles which, in turn, do not get rewarded with higher profits. A curvilinear risk‐return relationship is also observed which is consistent with previous theoretical suggestions. Implications for the strategic management of risk are then drawn.

Abstract Over the past 4 years research teams from INSEAD (Fontainebleau), Boston University and Waseda University (Tokyo) have administered a yearly survey on the manufacturing strategy of the large manufacturers of the three industrialized regions of the world. In this paper the results for the 1986 survey are compared. One of the most striking results of that year's survey is the emphasis some of the more advanced manufacturers put on their efforts to overcome the trade‐off between flexibility and cost efficiency. In particular for the Japanese respondents these attempts become clear. Europeans and North Americans are not yet seizing the opportunity to cut costs through rapid production and design changes, and are focusing more on traditional cost reduction programmes and the improvement of quality. This might mean that they are preparing the basis on which they can built to obtain added value from flexible automation. If this is the case then the Japanese are clearly ahead.

"The seven-fold increase, since 1920, in the labor force participation rate of married women [in the United States] was not accompanied by a substantial increase in average work experience among employed married women. Two data sets giving life-cycle labor-force histories for cohorts of women born from the 1880s to 1910s indicate considerable (unconditional) heterogeneity in labor-force participation. Employed married women had substantial attachment to their jobs; increased participation brought in women with little prior work experience. Average work experience among cross sections of employed married women increased from 9.1 to 10.5 years over the 1930-50 period. Implications for 'wage discrimination' are discussed."

Despite an extensive literature examining the effects of unions on wages, little attention has been paid to the resultant aggregate employment consequences of this change in the relative cost of unionized labor. This article uses 1983 Current Population Survey data to estimate the effects of union strength on the probability of employment and labor force participation. Union strength, which reflects both union coverage and the union wage differential, is found to decrease employment and increase unemployment by a small but significant amount. These effects are concentrated primarily among females and young males, while little impact is found on prime-age males.

The simplest economic theories of crime predict that profit-maximizing firms should follow strategies of minimal monitoring with large penalties for employee crime. We investigate possible reasons why firms actually spend considerable resources trying to detect employee malfeasance. We find that the most plausible explanations for firms' large outlays on monitoring of employees-legal restrictions on penalty clauses in contracts and the adverse impact of harsh punishment schemes on worker morale-are also consistent with the payment of premium (rent-generating) wages by cost-minimizing firms.

This study involves an empirical analysis of the effect of social security wealth on wealth accumulation. My analysis takes as its point of departure a study by Feldstein and Pellechio on this subject. Their study used the same data source as analysed in this paper. Feldstein and Pellechio found strong support for the notion that increases in social security wealth caused families to reduce their wealth accumulation. My resuts indicate the strong conclusions reached by Feldstein and Pellechio are not robust. In particular, first, when I excluded a group, of farmers from our sample increases in social security wealth did not result in families reducing their wealth accumulation. Second, Feldstein and Pellechio calculated social security wealth using income measures from a single year. When I applied their methodlogy to income measures from a different year results were markedly affected.

A model of consumption of residential energy in dwellings is developed, distinguishing between attributes of housing that provide direct benefits to consumers and attributes that serve as inputs in the production of final goods, for example, the thermal comfort of dwellings. Empirical estimates are made of the mode, based upon the Annual Housing Survey, and the results are used to calculate the effects of changes in energy prices on the consumption of housing, residential energy, and other goods. The analysis suggests that the adjustment process within the housing market permits a great deal of substitution in response to energy price changes. Copyright 1989 by MIT Press.

In recent months, the governors of several states have suffered major political embarrassments because actual revenues fell, substantially short of the predictions in their respective budgets. Such episodes focus attention on the question of whether states do a good " job of forecasting revenues. In modern economics, forecasts are evaluated on the basis of whether or not they are rational " do the forecasts optimal] y incorporate all information that is available at the tune they are made? This paper dr:vel ops a method for testing the rat i.onal t.y of state revenue forecasts, and applies it. to the aria lysi s of data from New Jersey, Massachusetts, arid Maryland.
