Impact of Population Aging on Japanese International Travel to 2025

In this paper we forecast Japanese international travel to 2025. In addition, to the usual economic variables, our model also captured both populations again and cohort effects on Japanese travel abroad. We predict the number of future Japanese overseas trips for males and females separately by five-year age groups and in five-year increments. We conclude that the Japanese will continue to travel abroad in increasing numbers but population aging will dramatically slow overall future Japanese overseas travel. While the number of "senior" travelers is predicted to increase sharply, we foresee fewer overseas trips taken by Japanese, especially among women, in the 20s and early 30s age groups. Finally, we examine the responses of the industry and the public sector in Japan to implications of a rapidly aging population on future international travel.

[Review of] Bill Hosokawa . Nisei-The Quiet Americans

Nisei, meaning American-born second-generation Japanese, is an epic scale undertaking of the recording of a brief but eventful history of the Japanese immigration to America by a Japanese American journalist. The book consists of twenty-seven chapters which are divided into three parts. The initial focus is on the settlement of the first generation Japanese immigrants in the 1870s, mainly in California and the Pacific states. Then the topic shifts to the emergence of a substantial Nisei population during the 1930-40 period, followed by their maturation through prewar segregation and the wartime internment experience. The third part accounts for the post-internment social ascension of Nisei as respected Americans, along with their success stories in practically every social position and professional field. In legal areas, the determined struggles of Nisei for equality and justice were finally fulfilled when their alien parents who had been ineligible for reasons of their racial origin were finally granted citizenship. Their efforts were extended into the 1960s until racial barriers were removed from the immigration law

Policy problems relating to the labor immigration control in Japan

This paper provides analyses of the following issues: i) The desirable Japanese admittance system of foreign workers, ii) The effects on the Japanese population structure and economy to which immigrants may have. The analyses insist that Japan should introduce the point system to examine the admittance of foreign workers, and grant permanent residence to them at the time of new entry, but the benefit from admitting immigrants would be small and diminish according to aging of the immigrants group.

Estimating a preference-based index from the Japanese SF-36

Objective: The main objective of the study was to estimate a preference-bascd Short Form (SF)-6D index from the SF-36 for Japan and compare it with the UK results. Study Design and Setting: The SF-6D was translated into Japanese. Two hundred and forty-nine health states defined by this version of the SF-6D were then valued by a representative sample of 600 members of the Japanese general population using standard gamble (SG). These health-state values were modeled using classical parametric random-effect methods with individual-level data and ordinary least squares (OLS) on mean health-state values, together with a new nonparametric approach using Bayesian methods of estimation. Results: All parametric models estimated on Japanese data were found to perform less well than their UK counterparts in terms of poorer goodness of fit, more inconsistencies, larger prediction errors and bias, and evidence of systematic bias in the predictions. Nonparametric models produce a substantial improvement in out-of-sample predictions. The physical, role, and social dimensions have relatively larger decrements than pain and mental health compared with those in the United Kingdom. Conclusion: The differences between Japanese and UK valuations of the SF-6D make it important to use the Japanese valuation data set estimated using the nonparametric Bayesian technique presented in this article.

Cost Efficiency and Scale Economies of Japanese Water Utilities

With the data of 831 Japanese water utilities from 1999 to 2008, we used the stochastic cost frontier analysis with a true fixed-effect model in order to estimate the cost efficiency and scale economies. We found that cost inefficiency was approximately 37%. The economies of water delivery volume were observed and found to be remarkably higher for small water utilities than for large ones. Scale economies were also discovered in small water utilities; however, scale diseconomies are likely to be incurred in larger water utilities. The optimal supply population size of a water utility is estimated to be 85,658 consumers, with a water delivery volume of 15.7 million m3 and a network length of 522 km.Cost Efficiency, Scale Economies, Optimal Size, Japanese Water Utilities

Studies on Maltese Consanguinity

The possible genetic consequences of consanguinity have been known from ancient times, though different societies have held varying views. Some have encouraged consanguinity as desirable and the classic examples are the sister brother marriages of the Egyptian Pharaohs and also of the ancient Irish and Inca Royal families. Mother-son, father-daughter marriages are only said to occur occasionally among the primitive tribes such as the Minahassa of Celebes. In certain countries, consanguinous marriages are very common. The Japanese population of nearly 100 million has a remarkable degree of inbreeding, reaching a consanguinity rate of approximately 20% in many districts, while in Central and Southern India many populated areas are claimed to have a 60% consanguinity rate. Inbreeding is typically common in isolate population, and small island communities or `closed' populations are most frequently associated with this phenomenon.peer-reviewe

Co-evolution and networks adaptation.

What is the role of co-evolution in the adaptation of a population of firms to a hostile environment ? To answer this question, we revisit network sociology starting from Kauffman s biological computer model. We apply a qualitative methodology to update exploitation and exploration mechanisms in nine Japanese interfirm networks. From these results, this article draws a typology of the adaptation forms, distinguishing pack, migratory, herd and colony networks.Sociologie des organisations; Réseaux d’entreprises;

Market Size and Entrepreneurship

In order to examine the impacts of market size on entrepreneurship, we estimate a monopolistic competition model that involves entrepreneurial decision by using data on Japanese prefectures. Our results show that a larger market size measured by the population density leads to higher incentive of people to become entrepreneurs. a 10 percent increase in the population density increases the share of people who wish to become entrepreneurs by 2 percent. In contrast, the self-employment ratio is lower in prefectures with higher population density, which suggests that the market size has different impacts on the entrepreneurship in different stages.market size, entrepreneurship, density economies, market expansion
