EVOLUTION AND SPONTANEOUS UNIFORMITY: EVIDENCE FROM THE EVOLUTION OF THE LIMITED LIABILITY COMPANY

We examine whether the unguided state-by-state evolution of limited liability company statutes has led to efficient interstate uniformity. Our evidence suggests significant uniformity has been produced in cases where the net benefits of uniformity are positive, and that such uniformity has not been produced by herd behavior. Our results are consistent with Alchian's intuition about the role of market processes, and suggests that the survival of efficient rules, fostered by the rational behavior of decentralized economic actors, are produced by forces beyond the control or foresight of individual lawmakers or legislatures.     

Gender,Social Bond,and Academic Cheating in Japan*

There is evidence that females are less likely to cheat than males on college campuses. A frequently offered but still untested explanation is that females, with a stronger sense of responsibility for the maintenance of social relationships, tend to develop a stronger bond to a conventional society—a key explanatory concept in Hirschi’s (1969) social control theory. With academic cheating as the dependent variable, we test the hypotheses that the four elements of social bond are the intervening variables linking gender to such dishonesty among Japanese students who, due to their stronger orientation toward masculinity on Hofstede’s (1980) scale of gender role separation, are subject to more gender distinct socialization, leading to greater gender differences in the strength of social bond than those previously reported in the United States. The analysis provides rather limited support for the theory, most of which is due to the stronger belief in the legitimacy of societal rules among the females.     

Process generating the ditribution pattern of eggs of the common cabbage butterfly,Pieris rapae crucivora

Summary The process generating the negative binomial in the distribution pattern of eggs of the common cabbage butterfly,Pieris rapae crucivora, was investigated by releasing the female adults in a net house where cabbages were planted. The distribution of butterflies visited and laid an egg or more per plant followed thePoisson series under the uniform light condition, while that of eggs laid per visit conformed to the logarithmic distribution. From these results, it may be concluded that the negative binomial arises from compounding of thePoisson and the logarithmic distribution. The observed frequency of eggs found per plant fitted to the negative binomial with parameter thus computed theoretically. The change in the degree of aggregation with the increase of the parental density was considered in connection with the above results.

Family structure and well-being at older ages in Japan

The family structure of older Japanese is projected to change dramatically as a result of very low fertility, increasing levels of non-marriage, childlessness, and divorce, and declining intergenerational co-residence. To provide an empirical basis for speculation about the implications of projected increases in single-person and couple-only households, we use two sources of data to describe relationships between family structure and the physical and emotional well-being of Japanese men and women aged 60 and above. We find that marriage is positively associated with self-rated health and emotional well-being among older men but not women. In contrast to expectations, however, we find only limited evidence that the presence of children contributes to well-being. Taken as a whole, our results suggest that declines in marriage may have negative implications for the well-being of older Japanese men while the implications of declines in fertility and intergenerational co-residence may be less than popularly believed.
