Constrained suboptimality in incomplete markets: a general approach and two applications

Summary. In this paper we re-examine generic constrained suboptimality of equilibrium allocations with incomplete numeraire asset markets. We provide a general framework which is capable of resolving some issues left open by the previous literature, and encompasses many kinds of intervention in partially controlled market economies. In particular, we establish generic constrained suboptimality, as studied by Geanakoplos and Polemarchakis, even without an upper bound on the number of households. Moreover, we consider the case where asset markets are left open, and the planner can make lump-sum transfers in a limited number of goods. We show that such a perfectly anticipated wealth redistribution policy, though consistent with the assumed incomplete financial structure, is typically effective.

Factors that influence physicians' recommendation of hospice care: An exploratory study

Palliative care and an array of attending services for terminally ill patients are available through over 2,465 hospices in the United States today. Although the actual number of terminally ill patients receiving hospice care has increased over the past decade, there is a growing concern of underutilization. Research has reported that despite meeting eligibility requirements only twenty-five percent of terminally ill patients have been served by hospice. Further, with a median stay of thirty days, the patients as well as their attending families may not be able to receive the full benefits of hospice care. In an effort to address these issues of underutilization, this exploratory study examines the relationship between physicians' referral behaviors and their awareness and perceived importance of selected hospice services, and agreement with hospice philosophy. Physician demographics and practice characteristics that are related to referral patterns are also identified.     

The Yonmenkaigi System Method: An Implementation-Oriented Group Decision Support Approach

The Yonmenkaigi System Method (YSM) is presented as a participatory method to support group decision making. It is composed of four main steps: conducting a SWOT analysis, completing the Yonmenkaigi chart, debating, and presenting the group’s action plan. The YSM is an implementation and collaboration-oriented approach that incorporates the synergistic process of mutual learning, decision making and capacity building. It fosters small and modest breakthrough and/or innovative strategy development. The YSM addresses the issues of resource management and mobilization as well as effective involvement and commitment by participants and provides a strategic communication platform for participants. A case study for developing a disaster reduction action plan, carried out with a local community organization in the City of Kyoto, Japan, is used to demonstrate the characteristics of the YSM.     

Tests of cointegrating rank with a trend-break

The conventional testing procedure may mislead one into accepting the null of no cointegration or the null of a cointegrating rank smaller than the true rank when there is a trend-break under the alternative hypothesis. This paper proposes tests for cointegrating rank that have power against the trend-break alternative. The proposed tests are applied to the US money demand function. The results support the Campbell–Perron conjecture: money, income and interest rates are cointegrated around a broken trend.     

Legal Protection,Corruption and Private Equity Returns in Asia

Although trustworthiness has been described as a source of competitive advantage, its value extends to organizational governance and wealth creation. We identify the importance of the commitment–compliance continuum in the decision to trust and note that trustworthiness is a subjective perception viewed through each person’s mediating lens. That lens and each person’s interpretation of the social contract impact one’s commitment to cooperate. We suggest five propositions that integrate trustworthiness, governance, and wealth creation.     

An Emergency Evacuation Planning Model Using the Universally Quickest Flow

In recent years, catastrophic disasters by massive earthquakes have been increasing in the world, and disaster management is required more than ever. In the case of disasters such as tsunamis, a slight delay in evacuation may deprive evacuees of life. In this article, we formalize the emergency evacuation planning model for evacuation from tsunamis and other disasters based on the idea of the universally quickest flow. We show that there does not always exist a universally quickest flow when the capacity constraint of refuges is taken into account. Therefore, we propose an alternative criterion that approximates a universally quickest flow, and presents an algorithm for finding an optimal flow for this criterion. Numerical experiments are carried out for the evacuation of a local city in Japan where tsunami damages are assumed to occur when a large earthquake occurs in the ocean nearby.

Top management team functional diversity and organizational innovation in China: The moderating effects of environment

While conflicts (cognitive and affective) have been considered as important process variables to better understand the mixed findings on the relationship between top management team functional diversity and organizational innovation, such an input‐process‐outcome model is still incomplete without considering the environmental factors. This study was formulated to assess the importance of both competitive and institutional environments in moderating such upper echelon effects within a transition economy. The chief executive officers and chief technology officers of 122 Chinese firms were surveyed and both competitive uncertainty and institutional support were found to shape top management team decision making processes and their outcomes.

Auction Reforms for Effective Official Development Assistance

Auctions, which are applicable to aid-related procurement systems, have been recently recognized as an important tool for improving economic efficiency. Using data on procurement auctions for Japanese official development assistance projects, the equilibrium bid function is estimated. The data reveals that a 1% increase in the number of bidders decreases the equilibrium bid by about 0.2%. This implies that strengthening competition at procurement auctions lowers contract prices and mitigates the heavy indebtedness of developing countries. Auctions are also instrumental in fostering local business environment and governance. For intensifying bidding competition, it is useful to introduce an electronic bidding system, encourage local firms to jointly bid, and relax excessive qualification requirements.
