Gender Differences in the Returns to and the Acquisition of On-the-Job Training

This article finds that gender differences in on-the-job training significantly affect the male/female wage gap. First, we find that previously trained workers exhibit larger cumulative wage gains during their current training. Thus, a substantial portion of the gender wage gap results from the fact that women have little prior training relative to men. Second, a significant amount of the observed male/female wage differential is explained by less female acquisition of current training. Gender differences in workplace promotion and training practices help explain why women accumulate less training than men. Both of these sources of gender differences have lessened from 1976 to 1985, which has led to a narrowing of the male/female wage gap.     

Job Security Provisions and Employment: Revised Estimates

This article provides estimates of the effect of statutory severance pay and notice on four labor market outcome indicators, closely following Lazear (1990) but correcting for errors in his dependent variables and covariates. Although we corroborate the directional influence of severance pay for three of the indicators, there is little to suggest that its contribution to rising unemployment is material. Also contrary to Lazear, longer notice appears to be associated with broadly favorable outcomes.     

Japanese/U.S. technological competitiveness and strategic alliances in the biotechnology industry

This paper analyzes the reasons for Japanese/U.S. collaborations in the biotechnology industry, and considers the question of whether such alliances pose a threat to the North American industry. Japan's technological competitiveness in biotechnology is examined in terms of its strengths and perceived weaknesses. Ways in which Japan is attempting to overcome these weaknesses are identified. As well, the strengths and weaknesses of the North American biotechnology industry are assessed. The paper concludes with recommendations for government and R&D managers on how to preserve U.S. competitiveness. R&D managers must keep abreast of their techno-global competitive environments. While organizations can enter into alliances to improve their competitiveness they must be aware of the dangers of collaboration, and to benefit from their alliances they must enhance their organizational learning. Organizations must be aware of the pitfalls of alliance formation, and any alliance must be viewed in its national context. Last, but not least, managers must be more effective in their management of the processes of technological innovation.     

Canadian Strike Replacement Legislation and Collective Bargaining: Lessons for the United States

Opponents of U.S. and Canadian strike replacement legislation contend that restricting the use of strike replacements significantly alters bargaining power and increases strike activity. This article uses data on Canadian manufacturing collective-bargaining agreements to investigate these hypotheses. Although a general ban on strike replacements is found to be associated with longer strikes, little evidence is found to suggest that banning permanent strike replacements significantly influences strike incidence, strike duration, or negotiated wages.     

Evolutionary Stability in the Investment-Opportunism-Retaliation Game

Can economically efficient outcomes be obtained and sustained in the absence of externally enforced property rights? We study the evolutionary properties of a game that exhibits two well-defined Nash equilibria: one generates an inefficient outcome while the other set generates an efficient outcome supported by the potential for retaliation. Although standard forward-looking refinements eliminate the efficient equilibrium, neither equilibrium type satisfies strict evolutionary stability criteria. However, both types of equilibrium define strategies that are neutrally stable, which makes them vulnerable to drift in dynamic environments. We conduct computer simulation experiments in which players learn adaptively via a tournament selection mechanism called sophisticated experimentation. Our simulations demonstrate that while the system spends a disproportionately high proportion of time in the inefficient equilibrium set, the efficient equilibrium is pervasive as the system drifts back and forth between the equilibrium sets, never settling on one or the other.     

A First Assessment of Some Measures of Core Inflation for the Euro Area

Abstract. Core inflation plays an important role in the deliberations of monetary policy-makers. In this paper we evaluate a number of measures of core inflation constructed using euro-area data. In addition to the traditional exclusion-type core measures, we examine two newer ones, documenting their properties and evaluating their performance in terms of their ability to track underlying or trend inflation in real time. We focus on core measures derived from the Harmonized Index of Consumer Prices (HICP) as the European Central Bank has chosen to define its mandate for price stability in terms of this index, and because this is the only index of consumer prices that is compiled in a comparable manner across all members of the European Union. We document significant excess kurtosis in the cross-section distribution of price changes in the euro area, and show that several categories of prices are more volatile than those typically excluded from traditional measures of core inflation. Contrary to what one might expect, traditional measures of core inflation are not significantly less volatile than headline measures. We document the superior performance of alternative measures of core inflation in tracking trend inflation on average, but show that none of the various measures of core gave significant advance warning of the pickup in trend inflation at the beginning of 1999.     

The Mode of Acquisition in Takeovers: Taxes and Asymmetric Information

We develop a model in which the mode of acquisition conveys information concerning the value of the bidder. The model incorporates the possibility that offers containing both cash and stock can be made in a setting consistent with the U.S. tax code. We demonstrate that bidders with unfavorable private information about their equity value choose offers containing some stock to avoid the capital gains tax consequences of cash offers. The model yields a number of unique predictions about the construction of acquisition offers. We present evidence consistent with the model.     

Participative Bureaucracy and Productivity in the Machined Products Sector

In a participative bureaucracy, group-based employee participation mechanisms provide opportunities to reexamine old routines and to take advantage of informal shortcuts that employees have worked out on their own. Instead of proving to be dinosaurs, older and larger bureaucratically structured organizations are demonstrating a capability for adaptation and change and achieving new productivity advantages through such participative structures. For small firms, a participative bureaucracy is complementary to the productive use of information technology in the machining process.     

石油价格进入更加波动的新时期

通过对油价波动的历史原因、市场内在因素和人为因素的分析可以看出，石油市场已进入一个新时期，油价将变得更加动荡，而且在波动中呈上升趋势。预计新的平均价位大体为每桶20美元。为此，石油公司应积极研究贸易策略，一方面设法使自身免受损失，另一方面还要寻求从价格波动中赢利。只有准备充分，才能够抗御油价的剧烈波动和周期性变化，进而获得生存与发展。
