JOINT BIDDING,GOVERNANCE AND PUBLIC PROCUREMENT COSTS:A CASE OF ROAD PROJECTS*

ABSTRACT *** : To utilize public resources efficiently, it is important to take advantage of competition in public procurement auctions to the maximum extent. Joint bidding is a common practice that potentially facilitates competition. By pooling financial and experiential resources, more firms are expected to enter the market, but it will also directly reduce competition if more than one bidder who is solely qualified makes a coalition. In theory joint bidding may or may not be beneficial to auctioneers, depending on the model. The paper empirically examines the impacts of joint bidding on firms' entry as well as bidding behaviour, using data on public road projects in developing countries. It shows that coalitional bids, in particular by local firms, would be competitive, but foreign joint ventures would undermine competition. It is also found that good governance can encourage firms' entry into the tendering and facilitate joint bidding practices.     

Potential Welfare Criteria and the Choice of Large Projects

This note compares project evaluation rules for large projects by Negishi (1962) and Harris (1978) and points out that the extensions by Harris depend on his implicit weakening of the criterion for potential welfare improvement compared with Negishi's original welfare criterion.

The Stability of the Japanese Banking System: A Historical Perspective

In this paper we study the stability of the Japanese banking system in the prewar period. First, we review the development of the Japanese banking system from the Meiji Restoration until the Second World War. It will be shown that government policy toward the banking industry changed drastically after the 1927 banking panic. Second, we examine the causes of bank closings in 1927. We test whether or not such bank closings were due to their unsound management, which was reflected in the structure of assets and liabilities and bank performance, using a qualitative model. Our empirical results conclude that bank closings occurred more for banks with unsound management and inefficient operations. J. Japan. Int. Econ., December 1993, 7(4), pp. 387–407.

A general theorem on tariff harmonization

This paper proves a general theorem on welfare improving tariff changes that a tariff harmonization towards any arbitrary common target tariff rates among member countries can improve potential world welfare as long as international lump-sum transfers are available.     

The differences in the economic effects between the DB plan and the DC plan

This paper investigates the differences between the defined benefit plans (DB) and the defined contribution plans (DC) in the enterprise pension programs in Japan. Attention is paid not only to the effect of labor turnover but also to the difference in various categories of workers, which are classified by gender, education, timing of labor turnover, etc. Also, we take into consideration the effect of interest rates. One important conclusion of this paper is that the DC plan is superior to the DB plan, in contrast to the common belief. J. Japanese Int. Economies 18 (4) (2004) 551–564.     

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.     

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.     

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.

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.     

Price Fluctuations and Growth Patterns in Singapore's Trade, 1831–1913

Using a newly created trade price index, this paper determines the real growth rate of Singapore's trade during 1831–1913. We find that Singapore's trade grew between 1831 and 1873 at a higher rate than during the later period. An analysis of the terms of trade and purchasing power parity reveals that the growth pattern of Singapore's entrepôt trade changed after 1850 from growth fuelled by transit trade of industrial products to balanced growth between regional imports and exports. This change resulted from the operation of the international monetary system, which enhanced market integration between Britain and Southeast Asia via Singapore.
