Equal Employment Opportunity Law and the gender wage gap in Japan: A cohort analysis

In this article, I perform a cohort-based analysis of the female-to-male wage gap using aggregate data in Japan from 1975 to 2005. While the inter-cohort closing in the gender wage gap is apparent, the convergence is smaller when the gap is calculated for each level of education. This pattern suggests that a certain portion of the gender wage convergence is due to changes in the educational composition of the workforce. I find that educational composition changes played a larger role in closing the pay gap for younger cohorts than it did for older cohorts. Highly educated women who entered the labor market after the enactment of the Equal Employment Opportunity Law gained in that they had more regular full-time employment but did not experience wage gains relative to their male counterparts.     

A geometric approach to temptation

We provide a simple geometric proof of the Gul and Pesendorfer’s (Gul and Pesendorfer, 2001) utility representation theorem about choice under temptation without self-control. We extract two incomplete orders from preferences: temptation relation and resistance relation. We characterize those relations geometrically and obtain temptation utility using a separation method à la Aumann (Aumann, 1962).     

Japanese business culture: the government,mainstream enterprises and ‘mavericks’ in the steel industry

Some scholars have argued that Japanese business epitomizes organized capitalism, and no-one would deny that the government and trade associations were pivotal in the distinctive development of Japanese capitalism. But it is frequently emphasized that competition between firms was fierce. One interpretation is that Japanese firms co-operated in developing technologies, and also collaborated in pricing policy, output allocation and capital investment. This collaborative endeavour gives the impression of a business environment that was static and collusive. By contrast individual firms competed aggressively in the improvement of the product quality, in productivity and in marketing. Infrequently a few determined firms refused to follow government guidance and openly challenged it. Two examples, Kawasaki Steel in 1950 and Sumitomo Metal in 1965, require a wider perspective than business-government relationships. It is the triangular matrix of government, mainstream firms, and ‘mavericks’ that has to be considered. Mainstream firms have a close relationship with government and try to impede the aggressive behaviour of ‘mavericks’. Exploring these tripartite interactions is crucial to any understanding of Japanese industry.     

Towards a new business history?

This article calls for a discussion about business history research. We advocate that the current typical approach in business history – dominantly case study analysis – maintains its prominent position, but the purpose and relevance of this type of research in the scientific method for business history is made more explicit. Moreover, the article proposes the application of additional approaches in business history, which specifically aim to develop theory and test hypotheses. These approaches are well established in the social sciences, but require adaptation to the particular needs of business history. The purpose of this article is to argue that opportunities for scientific explanations in business history are enhanced by engagement with the circle of knowledge creation where theory is confronted with empirical evidence and empirical observations feed back into theory formation.     

Incumbent’s price response to new entry: The case of Japanese supermarkets

Large-scale supermarkets have rapidly expanded in Japan over the past two decades, partly because of zoning deregulations for large-scale merchants. This study examines the effect of supermarket openings on the price of national-brand products sold at local incumbents, using scanner price data with a panel structure. Detailed geographic information on store location enables us to define treatment and control groups to control for unobserved heterogeneity and temporary demand shock. The analysis reveals that stores in the treatment group lowered their prices of curry paste, bottled tea, instant noodles, and toothpaste by 0.4–3.1% more than stores in a control group in response to a large-scale supermarket opening.     

Who benefits from bond tender offers in Europe?

This paper investigates the wealth effects of European cash tender offers for bonds during the period from 1996 to 2005. European bond offers are made to refinance (35% of cases), to reduce debt (40%) or triggered by an ownership change (25%). We investigate the wealth effects to both bondholders and shareholders. Cash tender offers for bonds turn out to be value creating for firms; with bondholders taking most of the gains on a relative basis. We find no evidence of wealth transfers from shareholders to bondholders: bondholders are paid an average tender premium of 3.9% but shareholders do not experience a significant wealth loss. Shareholders even benefit from making refinancing bond tender offers after a drop in interest rates. The wealth effects to both bondholders and shareholders increase in the remaining time to maturity. This suggests that tendering the bonds, rather than waiting for them to mature, is a win-win situation for both types of security holders.     

Tied Aid and Welfare

In this paper we present a model of tied aid to shed light on the dispute between Kemp and Kojima (1985 ) and Schweinberger (1990 ) and to complement their analyses. We show that if the households of the recipient country are not informed of the transfers at their consumption decision, they have an incentive to trade the purchased goods from their domestic production income whenever transfer paradoxes occur. We also demonstrate that when they are aware of the transfers and can trade the purchased goods from their production income, there are no transfer paradoxes under the normality condition of commodities.     

IS THERE A SIGNALING EFFECT OF UNDERWRITER REPUTATION?

In this article we examine the effect of underwriter reputation on the abnormal return due to an announcement to issue seasoned new equity. After controlling for other factors that relate asymmetric information to abnormal returns, underwriter reputation still significantly reduces the magnitude of the negative announcement effect. We also develop a procedure to extract a signaling component from the measure of underwriter reputation. We show that the signaling component of underwriter reputation positively and significantly affects abnormal returns. This result supports the notion that issuing firms use underwriter reputation as an effective instrument to signal that their stocks are not overvalued. JEL classification: D82, G24, G30
