The cournot-nash and cooperative solutions in the harvesting of a fish stock

The questions of optimal extinction and of market imperfections in the harvesting of a fish stock is analyzed using two different objective functions, one discounted utility of fish consumption and the other discounted profit, both over an infinite horizon.     

RELATIONSHIP BETWEEN BUSINESS DEFINITION AND CORPORATE GROWTH: THE EFFECT OF FUNCTIONAL ALIGNMENT

Abstract. In previous research, the hypothesis drawn from Theodore Levitt's idea that companies could continuously grow by ‘functional’ business definitions was statistically proved with 50 Japanese electric/electronics companies. The current research tests the hypothesis that in the case where the functions in corporate business definitions, divisional business definitions and products and services are all aligned, it will ultimately bring continuous growth to the company, through case studies and content analysis of four companies with highly functional corporate business definitions. As a result, it is proved that the company that successfully aligns the functions on every level continuously grows at a higher rate than the others.     

Semiparametric Model of Hedonic Housing Prices in Japan

We propose a semiparametric hedonic model of housing prices with nonlinearity in age and cohort effects. The model avoids the simultaneity problem among age, cohort and year effects, which is a common problem in linear hedonic models. Applying the model to housing prices in Tokyo between 1990 and 2008 revealed significant nonlinearities in both the age and cohort effects, and significant interactions between these effects, with the shape of the age effect differing across housing cohorts. Estimates of the year effect indicated a declining trend in prices that was more pronounced compared with those of conventional linear hedonic models.     

The Impact of Regional Factors on the Start‐Up Ratio in Japan*

We analyze regional factors of the start‐up ratio in Japan using two datasets with different regional aggregation levels. The explanatory variables represent demand, cost, human resource, financial, industry agglomeration and industrial structure, and other factors. The empirical results demonstrate that even though all these factors significantly affect the start‐up ratio at the municipality level, some of these factors are not significant at a larger economic area level. In particular, we obtained evidence that human resource factors, together with the average wage and average size of establishments, are important determinants of the regional start‐up ratio in both the samples.     

Real exchange rate appreciation,resource boom,and policy reform in Myanmar

Over the six‐year period 2006‐11, the real exchange rate of the Myanmar kyat appreciated 200 per cent, resulting in the value of the US dollar in Myanmar falling to one‐third of its pre‐2006 level. While the resource boom is suspected to be the source of the real exchange rate appreciation, administrative controls on foreign exchange and imports had much more impact. Foreign exchange controls limited the convertibility of the kyat to foreign currencies and spurred negotiated transactions of foreign exchange outside the banking sector, hampering the foreign exchange market interventions of the government and Central Bank. Import controls repressed imports, aggravating excess supplies of foreign exchange. Relaxation of administrative controls is necessary for moderating currency appreciation.     

A model for evaluating extreme risks with stochastic sustainability criteria: a case study of soil remediation on landfill sites

This article addresses the issue of risk management for extreme events. The term stochastic sustainability will be defined in relation to the risk management of extreme events. On the basis of stochastic sustainability, a risk evaluation function is defined as an efficient reserve to remedy contaminations just as a premium rating in insurance policy. A term of generalized safety loading is used as a key concept to evaluate the degree of extremeness of risk. A simple model of the environmental or infrastructure systems is used to illustrate the procedure of risk evaluation where stochastic sustainability is required in case of accidental

environmental contamination. A case study of soil contamination at landfill sites is presented as an example to test this risk evaluation function.     

Trade Gains in Chaotic Equilibria

It is shown by means of an overlapping-generations (OLG) example that free international trade may be both deterministically chaotic and gainful in the sense of Pareto to a participating country.     

RELATIONSHIP BETWEEN BUSINESS DEFINITION AND THE LONG‐TERM GROWTH OF COMPANIES: IS LEVITT RIGHT?

Abstract.  Theodore Levitt argued that organizational growth can be threatened because firms define their businesses incorrectly. He believed that businesses should be defined in terms of 'needs', not 'products', if they are to survive in the long term. In this paper I investigate the relationship between business definition and the long-term growth of companies in order to prove Levitt's idea. I statistically analyse relationships between past business definitions and financial performance up to the present using 50 Japanese electric/electronics companies. I find that there is a clear relationship between 'functionality' of a business definition and long-term growth in sales and aggregate market value.     

A Second Elementary Proposition Concerning the Formation of Customs Unions

The conclusions of the 1976 Kemp–Wan proposition are shown to be valid even if, after the formation of a customs union, the tariff vectors of some non-member countries are optimally chosen.

A factor endowment theory of international trade under imperfect competition and increasing returns

Abstract.  Constructing a two‐good (competitive and imperfectly‐competitive goods), two‐primary factor (capital and labor) and two‐country model of international trade where the imperfectly‐competitive sector is subject to increasing returns to scale, we establish an oligopolistic version of the Heckscher‐Ohlin theorem.
