It is important to respond to customers' requirements more rapidly than ever before due to the recent trend in e-business and its technologies. In order to achieve an agile response, we have to manage business models, to reflect the changes in the models and to develop or modify IT systems for further chances. This paper proposes a management framework of layered enterprise models. The proposed framework consists of a business model repository and a software repository, and defines three different grain sizes of modeling layers, namely business modeling, business process modeling and business application modeling, in order to support business modeling and application development. This framework helps us to develop business application in incremental deployment of analysis, design, and implementation to execute business processes. We have implemented a prototype environment using Java. Each repository's contents are described using XML so that the repositories are interoperable. Copyright © 2003 John Wiley & Sons, Ltd. 相似文献

We attempt to compare adjustment costs under exchange rate regimes in East Asian economies during their recovery processes. The criteria are the degree of overshooting in exchange rates, the changes in country risks, and the severity and duration of the recovery processes. Linear ranking is difficult. Managed rates with capital control worked for macroeconomic performance despite the welfare loss due to blocking capital flows. The currency board system worked well for stability, but recent experiences of Argentina and Hong Kong were deflationary. Under flexible rates, many economies that received IMF grants suffered a drastic initial downturn but later recovered vigorously. JEL Classification Numbers: F31, F32, F33. 相似文献

This paper constructs a North–South quality-ladder model in which foreign direct investment (FDI) is determined by the endogenous location choice of firms, and examines analytically how strengthening patent protection in the South affects welfare in the South. Strengthening patent protection increases the South's welfare by enhancing innovation and FDI, but it also allows the firms with patents to charge higher prices for their goods, which decreases welfare. However, the model shows that the former positive welfare effect outweighs the latter negative effect. Moreover, introducing the strictest form of patent protection in the South, that is, harmonizing patent protection in the South with that in the North, may maximize welfare in the South as well as in the North. Further, a similar result can also be obtained in a nonscale effect model. 相似文献

In this paper, we investigate how strengthening patent protection affects economic growth in an endogenous growth model where both innovation and capital accumulation are the driving forces of economic growth. In this model, stronger patent protection raises the profit flow obtained by innovation but reduces the factor demand for capital. This process accelerates innovation but discourages capital accumulation, and because of the negative effect on economic growth through reducing capital accumulation, strengthening patent protection may then impede economic growth. This result contrasts with earlier studies where innovation is the sole driving force for economic growth. Moreover, in an open economy model where technologies are transferred and capital is imported from abroad, the strictest protection of patents enhances technology adoption from abroad but impedes capital accumulation, and thus, the relation derived between patent protection and output can be nonmonotone. In terms of implications, these findings may be able to partly explain the complex relation found by some empirical studies in this area. 相似文献

This paper explores optimal taxation of market purchases of an elderly care service, which can also be produced in the home. Home production cannot be taxed. If children discount parents' utility relative to their own utilities, an intergenerational externality arises in the family. When home production of the service is significant, the optimal tax rate on market purchases should be: (i) high , if the service and leisure are complements and the externality is strong, (ii) low , if they are substitutes , irrespective of the degree of the externality. 相似文献

This paper formalizes two different principles to socially rank allocations under efficiency-equity trade off. The efficiency-first social preference relation ranks an allocation x higher than an allocation y if and only if (i) x is Pareto-superior to y or (ii) x and y are Pareto-noncomparable and x is equity-superior to y. The equity-first social preference relation reverses the order of application of the two criteria. We show that the efficiency-first relation may have a cycle, whereas the equity-first relation is transitive. We also characterize and compare the sets of maximal elements for these social preference relations in the Edgeworth box and examine the nonemptiness of the sets.

The strong performance of the Japanese economy, rising stock and land prices in Japan, as well as the strong yen, have prompted Japanese to travel abroad in ever increasing numbers in recent years. Despite several obstacles against growth, such as limited vacation time for employees of Japanese corporations, relatively expensive airline tickets, capacity limitations of international airports in Japan, booming resort development in Japan itself, and imposed constraints on Japanese direct investment abroad, Japanese travelers abroad, the majority of whom are tourists, increased from less than five million in 1985 to almost 10 million in 1989. The traditional demand function based on income and price may not explain all of the growth of Japanese overseas tourism, since some of the increase in Japanese travelers may stem from increases in expected future income based on increased wealth. This wealth effect hypothesis is tested using a log-linear regression model. It is found that wealth is a better predictor of overseas tourism levels than income. The effect of wealth increases on overseas tourism is also found to have a lag time of about one year. For this reason, it is proposed that the slowing in the Japanese economy this year will negatively impact Japanese overseas tourism next year. 相似文献

This paper investigates the relationship between utilitarianism and horizontal equity in models of income taxation in particular and self-selection in general. An example involving well-behaved individual preferences is constructed in which a maximization of a utilitarian social welfare function leads via income taxation to horizontal inequities. Sufficient conditions for utilitarianism to bring horizontal equity are derived. The results are applied to the question of whether income tax credits are an appropriate way to treat differences in family size. 相似文献

In recent years public health problems caused by indoor air pollution, known as ‘Sick Building Syndrome in housing’, or ‘Sick House Syndrome’ in Japan, have been drawing strong public concern. After conducting extensive exposure assessment, government authorities have taken effective measures to solve the problem. However, as a result of diversification and increase in quantities of industrial chemicals, existing regulations do not cover enough ranges of various potential hazardous chemicals. Hence, the regulations seek to be changed from hazard‐based regulation to a risk‐based one. Good indoor air quality (IAQ), which does not pose unacceptable health risks from all pollutants affecting indoor air, should be ensured for all public people. The objective of this study is to clarify the remaining issues to be solved urgently, related to the regulations to ensure a good IAQ. We reviewed enormous numbers of the existing governmental and industrial voluntary standards and/or guidelines, literature and documents concerning IAQ research in the past 40 years. Our results showed six subjects from those remaining issues. Based on these subjects we created a new scheme to control the IAQ; we especially regarded a comprehensive labeling system as one of the important strategies. 相似文献
