Comparison between specific taxation and volume quotas in a free entry Cournot oligopoly

We revisit the classic discussion of the comparison between tax and quota, but in a free-entry Cournot oligopoly. We investigate a quantity ceiling regulation as a quota policy. We find that tariff-quota equivalence holds if the firms are symmetric and the number of firms is given exogenously. However the equivalence does not hold and taxes dominate quotas in the free entry market because quota can increases the number of entering firms and increases the loss caused by excessive entries.     

International duopoly with overseas production and strategic trade policies

This paper examines the strategic export policies in a reciprocal market model of an international Cournot duopoly where two firms in domestic and foreign countries reciprocally supply their products to other countries through overseas production as well as export. It also considers the fact that the firms must incur export costs in addition to production costs. Thus, this paper shows, among others, that the effects of export policies on firms' output and export choices do not depend on the slopes of firms' reaction curves. It is also shown that firms' total outputs are independent of the export policies, and the optimal domestic and foreign export subsidies are zero (laissez-faire).     

Location and competition in retail banking

We investigate the impact of banking deregulation during the 1990s on consumer welfare. We estimate a spatial model of consumer demand for retail bank deposits that explicitly accounts for consumer disutility from distance traveled. This is important given the substantial changes in banks' branch networks observed in the data. Our model indicates that cross-price elasticities between banks whose branches are close to consumers (‘close’ banks) are larger than those between ‘far’ banks and more than double the cross-price elasticity of ‘close’ banks with respect to ‘far’ banks. We distinguish between thrifts and other banks and find that within-thrift competitive effects are stronger than within-bank effects or those between thrifts and banks. We use our estimates to predict the effect of changes in market structure on consumer welfare following the branching deregulation of the Riegle–Neal Act of 1994. Our results indicate that the median household gained around $60 per year from the changes. Approximately two thirds of the gains come from within-market changes in market structure. The gains were greater in markets with high initial numbers of banks than elsewhere.     

Bid Roundness Under Collusion in Japanese Procurement Auctions

We analyze the “roundness level” of bids—defined as the number of zeros at the end of the bid—in public procurement auctions for construction works in Okinawa Prefecture, Japan, where a bid-rigging case was filed. We hypothesize that bid rigging increases the roundness of bids through the bid coordination process. Specifically, winners choose round numbers to avoid any miscommunication when they announce their planned bids to other ring members, and losers prefer round numbers when they arbitrarily bid above the winning bid. We find that (1) there is a positive relationship between the roundness of a bid and its relative value as a fraction of the reserve price, (2) the roundness of bids is higher when collusion is active than when it is inactive, (3) among the ring bids, the roundness of the lowest bids is even higher than that of the other bids, and (4) bids by non-ring members are also round when collusion is active.     

Product R&D Investment Policies in an International Duopoly

This study analyzes the optimal product R&D investment policies of a developed and a developing country in an international Cournot duopoly where firms from these two countries compete through endogenous quality–quantity decisions. We explore a new international trade model by using demand functions derived from utility functions. We find that the optimal product R&D investment policies for both countries are subsidies. This study counters a finding that used Hotelling‐type demand functions and it partially modifies another result that adopted the same demand functions but with an international Bertrand duopoly.     

Development of educational program for production manager leading new perspectives on manufacturing technology

In this paper, we consider the problems associated with the development and management of an educational program for manufacturing managers in leadership roles who are making contributions towards the creation of customer delight as well as customer satisfaction using manufacturing technology. The basic concept combines an intelligent knowledge-based approach with the kaizen activity program within the framework of value creation and comparative advantage models based on a network referred to as Academia, Business, Consultancy, and Government (ABC-G). This educational program, which reflects the characteristics of manufacturing technologies and practices in the Hokuriku District of Japan, was developed in 2005–2006 and the trial education was developed in 2005 and 2006, and a trial run of this program was conducted in 2006 and 2007 in close collaboration with local manufacturing companies and their employees. The results are informative of the effects of educating manufacturing managers in Japan and the problems that will have to be overcome for the continuous improvement of the program.     

The effects of oil price shocks on expenditure category CPI

In this study, we apply a two-block structural vector autoregressive (VAR) model proposed by Kilian and Park (2009) in order to investigate the dynamic effects of changes in oil price on the expenditure category consumer price index (CPI) in the United States and Japan. Our results confirm that each expenditure category price index responded very differently to the same structural shock, and that whether changes in oil price function as a positive stimulus or a negative shock for the individual expenditure category prices also depends on the kind of underlying shock that drives the changes in oil price. Finally, our results also reveal that the manner in which changes in oil price affect each expenditure category price differs between the United States and Japan and these detailed-level differences may lead to aggregate-level differences in the price response of both countries to changes in oil price.     

How does the entrepreneurial orientation of scientists affect their scientific performance? Evidence from the quadrant model

In order to identify the effect of academic entrepreneurship on science, this work compares the publication performance of entrepreneurial scientists with that of conventional scientists. Using Stokes's ‘quadrant model’, this paper examines how the entrepreneurial orientation affects scientific performance. The results on advanced materials research in Japan found that (i) entrepreneurial scientists publish more papers than conventional scientists do; (ii) the papers of conventional scientists demonstrate better citation performance than those of entrepreneurial scientists do, on average; (iii) coming to the top-cited papers, entrepreneurial scientists show higher propensity for publishing high-impact papers than conventional scientists do; and (iv) the portfolio interdisciplinarity of papers authored by entrepreneurial scientists is higher than that of conventional scientists. Although the influence of academic entrepreneurship on scientific performance is still unclear, our findings suggest that entrepreneurial scientists could make a relatively large contribution to furthering the scientific frontier by relying on innovation rather than convention.     

Acquirer-target social ties and merger outcomes

This article investigates the effect of social ties between acquirers and targets on merger performance. We find that the extent of cross-firm social connection between directors and senior executives at the acquiring and the target firms has a significantly negative effect on the abnormal returns to the acquirer and to the combined entity upon merger announcement. Moreover, acquirer-target social ties significantly increase the likelihood that the target firm?s chief executive officer (CEO) and a larger fraction of the target firm?s pre-acquisition board of directors remain on the board of the combined firm after the merger. In addition, we find that acquirer CEOs are more likely to receive bonuses and are more richly compensated for completing mergers with targets that are highly connected to the acquiring firms, that acquisitions are more likely to take place between two firms that are well connected to each other through social ties, and that such acquisitions are more likely to subsequently be divested for performance-related reasons. Taken together, our results suggest that social ties between the acquirer and the target lead to poorer decision making and lower value creation for shareholders overall.
