Environmental assessment and protection are important concerns in modern business. Consumers are interested in corporate effort and investment for environmental protection. It can be easily imagined that they avoid purchasing products from dirty-imaged companies even if their prices are much...

Environmental assessment has recently become an important business concern because consumers are interested in environmental protection. They try to avoid purchasing products from dirt-imaged companies, which do not pay attention to environmental protection, even if their prices are much less...

The economic concept of weak and strong disposability has long dominated studies on DEA (Data Envelopment Analysis) environmental assessment. This study reviews the two disposability concepts from their conceptual and methodological implications. In particular, this study is interested in the...

Climate change and global warming become a major policy issue in the world. Economic activities produce not only desirable outputs (e.g., electricity) but also undesirable outputs (e.g., CO2 emission). The important policy issue is how each nation can balance between economic development and...

We analyze the consumption and wealth inequality in an OLG model with mandatory pension systems. Our framework features within cohort heterogeneity of endowments and heterogeneity of preferences. We allow for population aging and gradual decline in TFP growth. We show four main results. First,...

We analyze the effects of increasing the retirement age in two economies with overlapping generations and within cohort ex ante heterogeneity. The first economy has a defined benefit system, and the second economy is in transition from a defined benefit to a defined contribution. We find that if...

A balance between industrial pollution prevention and economic growth becomes a world-wide issue to develop a sustainable society in many industrial nations. To discuss the issue, this study proposes a new use of DEA environmental assessment to determine how to effectively allocate capital for...

In a simple parametric general equilibrium model with S states of nature and K < S firms - and thus potentially incomplete markets-, rates of super majority rule p€[1/2, 1] are computed which guarantee the existence of p -majority stable production equilibria : within each firm, no alternative production plan can rally a proportion bigger than p of the shareholders, or shares (depending on the governance), against the equilibrium. The smallest p are obtained for announced production plans whose span contains the ideal consumptions of all K mean shareholders. This is done under various governances. These rates of super majority are shown to be always smaller than Caplin and Nalebuff (1988, 1991) bound of 1-1/e ~ 0.64. Moreover, simple majority production equilibria are shown to exist for any initial distribution of types when K=S-1, and for symmetric distributions of types as soon as K > S/2. Finally, through parametric examples, these rates are shown to decrease with the homogeneity of the shareholders' beliefs on the probabilities of the states of nature, and to increase with the shareholders'...</s>
