COLLUSION FACILITATING AND COLLUSION BREAKING POWER OF SIMULTANEOUS ASCENDING AND DESCENDING PRICE AUCTIONS

This article demonstrates that a robust tacit collusion evolves quickly in a "collusion incubator" environment but is destroyed by the simultaneous descending price auction. Theories of collusion-producing behavior, along with the detail of the states on which strategies are conditioned, lead to a deeper understanding of how tacit collusion evolves and its necessary conditions. These theories explain how the descending price auction destroys the collusion. The experiments proceed by conducting simultaneous ascending price auctions in the collusion incubator. Then, once the tacit collusion developed, changing to the descending auction. The change moved prices from collusive levels to near-competitive levels. ( JEL C71, C92, D43, D44)     

COLLUSION IN PROCUREMENT AUCTIONS: AN EXPERIMENTAL EXAMINATION

Experimental methods are used to examine the existence and detectability of collusion in environments that exhibit critical parallels to procurement auctions. We find that given the opportunity sellers often raise prices considerably. Moreover, noncollusive Nash equilibrium predictions are insufficient to dismiss "suspicious" behavior as innocuous: in an environment where identical prices are predicted in a noncollusive Nash equilibrium, common prices are observed only when sellers communicate. In a second environment designed to parallel construction procurement contracting, market rotations are observed both with and without collusion, but collusion can often be detected from the pattern of losing bids.     

AN EXPERIMENT ON INNOVATION AND COLLUSION

This paper examines the relationship between product innovation and the success of price collusion using novel laboratory experiments. Average market prices in low innovation (LO) experiments are significantly higher than those in high innovation, but otherwise identical experiments. This price difference is attributed to LO experimental subjects' greater common market experience. The data illustrate how collusion can be perceived as the “only way to make it” in LO markets where product innovation is not a viable strategy for increasing profits. They suggest that product homogeneity can be a proximate cause, and product innovation an ultimate cause, of collusion. (JEL L41, L10, C92)     

INFORMATION SHARING AND TACIT COLLUSION IN LABORATORY DUOPOLY MARKETS

This paper reports 45 laboratory duopoly markets that examine the importance of information sharing in facilitating tacit collusion under conditions of demand uncertainty. Sellers in these repeated laboratory markets generally shared information when possible to reduce their demand uncertainty, which led to output reductions in some demand states. Risk aversion is a likely explanation for this sharing, but some sellers also appeared to employ a strategy of information concealment to punish non-colluding rivals. Nevertheless, output choices were similar in control treatments that forced sellers to share or conceal information, so the information sharing itself did not substantially increase tacit collusion. ( JEL C92, D80, L13)     

COLLUSION AND OVERLENDING

This study provides a theoretical background for collusion-induced overlending being the main cause of the 1997 Korean financial crisis. Our model consists of a lending institution, a borrowing chaebol of an unknown type, and an informed politician who can influence lending decision. We show that collusion can be formed between a low-type chaebol and the politician, and it may not be the lending institution's best interest to deter such collusion. This equilibrium, however, is possible only when the economic environment is favorable. When the economy deteriorates, the expectations of the fall of the collusion equilibrium can trigger financial crisis. (JEL G30, D82, O16)     

TRANSACTION COST, TWO-PART TARIFFS, AND COLLUSION

When two goods exhibit demand complementarity, the sellers would generally charge lower prices under collusion than under rivalry–a cartel internalizes cross effects that independent firms ignore. For the particular case of "two-part" tariffs consisting of entrance fees and per-unit prices, this paper shows that entrance fees are indeed lower under collusion than under rivalry, but that per-unit prices are unaffected. The demand complementarity arises from transaction costs borne by consumers who enter the market. The policy implication is that collusion can be socially preferable to competition in the presence of such transaction costs.     

EMISSION TAXES,CLEAN TECHNOLOGY COOPERATION,AND PRODUCT MARKET COLLUSION: EXPERIMENTAL EVIDENCE

We use a laboratory experiment to study the link between cooperative research and development (R&D) in clean technology and collusion in a downstream product market in the presence of a time‐consistent emissions tax. Such a tax creates additional interconnections between firms, in addition to the standard technological spillovers. Our results show a strong link between R&D cooperation and market collusion under symmetric R&D spillovers in a duopoly, but when the spillovers are asymmetric, R&D cooperation does not necessarily result in collusion. With symmetric spillovers, the link between R&D cooperation and collusion remains strong even in three‐ and four‐firm industries. (JEL C90, L5, O30, Q55)     

COOPERATION SPILLOVERS AND PRICE COMPETITION IN EXPERIMENTAL MARKETS

Firms often cooperate explicitly through activities such as research joint ventures, while competing in other markets. Cooperation in research and development can allow firms to internalize the external benefits of knowledge creation and increase the returns from research and development (R&D) expenditures. Such cooperation may spill over to facilitate collusion in the market, however, potentially lowering welfare and efficiency. This paper uses a laboratory experiment to examine if sellers successfully coordinate to fund a joint research project to reduce their costs, and how this collaboration affects their pricing behavior. The experiment includes control treatments with separate R&D cooperation and markets. Our results show that although participants usually cooperate when given an opportunity, cooperation is observed less frequently when they also compete in the market. Communication improves cooperation in all environments, particularly when the market is present. Nevertheless, the data provide no evidence of seller collusion in the market.

POTENTIAL COMPETITION AND POSSIBLE COLLUSION IN FOREST SERVICE TIMBER AUCTIONS

Potential competition significantly affects the size of winning bids in Forest Service sealed-bid timber auctions and has little effect on winning bids in oral auctions. Winning sealed bids depend even more, however, on actual competition, a result suggesting collusion. This explanation is supported using an index representing the likelihood an auction was rigged. Preclusive bidding (a type of collusion) in oral auctions is indicated by a positive relationship between hauling distances and the size of winning sealed bids. Comparisons of winning-bid variances, overbids, and numbers of bidders across auction type support this explanation of oral auction prices.     

FORCED INFORMATION DISCLOSURE AND THE FALLACY OF TRANSPARENCY IN MARKETS

A theory advanced in regulatory hearings holds that market performance will be improved if one side of the market is forced to publicly reveal preferences. For example, wholesale electricity producers claim that retail electricity consumers would pay lower prices if wholesale public utility demand is disclosed to producers. Experimental markets studied here featured decentralized, privately negotiated contracts, typical of the wholesale electricity markets. Two conclusions emerge: (1) such markets generally converge to the competitive equilibrium and (2) forced disclosure works to the disadvantage of the disclosing side. Information disclosure would result in higher wholesale and thus higher retail electricity prices. (JEL L50 , L94 , D43 )     

SEX OF CHILDREN: A COMMUNITY ANALYSIS OF PREFERENCES AND PREDETERMINATION ATTITUDES

A self-administered questionnaire concerning child sex preferences and attitudes toward the exercise of pre- and post-conception sex predetermination was distributed and retrieved from an urbanized area sample of 209 adults aged 18 to 50. A modified (i.e., truncated) version of McClelland's (1979) "stopping rule" measure method was used to assess child sex preferences. It confirmed and extended findings from earlier research in that male first children, but sex-balanced completed families, were preferred by the respondents. The use of either pre- or post-conception techniques of sex predetermination was favored by only a minority of the respondents, a very small minority when by the postconception method. Finally, it was evident that child sex preferences did not have a significant influence upon fertility intentions or upon attitudes toward the personal exercise of sex predetermination by either method.     

EMPLOYER CHOICES IN EAP DESIGN AND WORKSITE SERVICES

In today's complex private healthcare market, employers have varied preferences for particular features of behavioral health products such as Employee Assistance Programs (EAPs). Factors which may influence these preferences include: establishment size, type of organization, industry, workplace substance abuse regulations, and structure of health insurance benefits. This study of 103 large employer purchasers from a single managed behavioral healthcare organization investigated the impact of such variables on the EAP features that employers select to provide to workers and their families. Our findings indicate that for this group of employers, preferences for the type and delivery mode of EAP counseling services are fairly universal, while number of sessions provided and choices for EAP-provided worksite activities are much more varied, and may be more reflective of the diverse characteristics, organizational missions and workplace culture found among larger employers in the US.     

WHAT MOTIVATES POLITICAL PREFERENCES? SELF‐INTEREST,IDEOLOGY, AND FAIRNESS IN A LABORATORY DEMOCRACY

Substantial prior literature has established that subjects in laboratory experiments are typically willing to sacrifice their own well being to make financial allocations more equal among participants. We test the applicability of this result in an environment that contains some of the key contextual issues that are usually excluded from more abstract games, but which might be important in situations involving income redistribution. Our general finding is that votes for a redistributive tax are almost entirely in accordance with self‐interest: above‐average earners vote for low tax rates and below‐average earners vote for high tax rates. A measure of subjects' preferences for fairness or equality, their self‐reported economic ideology, is not directly related to their voting behavior in this experiment. Because the ideology measure should be correlated with any intrinsic preferences regarding inequality aversion, we conclude that any preferences for fairness or inequality that our subjects possess are not strong enough to overcome self‐interest in this context. We do, however, find evidence for a possible indirect effect of ideology on choice behavior in that more conservative subjects tend to be more responsive to their self‐interest than the more liberal subjects.

CUSTOMER OWNERSHIP AND QUALITY PROVISION IN PUBLIC SERVICES UNDER ASYMMETRIC INFORMATION

The implementation of projects producing external effects is often a source of disagreement and conflict between hosting and nonhosting communities. The article focuses on the impact of participatory ownership on conflict resolution and social welfare in the presence of asymmetric information and imperfect quality monitoring. We show that in such situations the participatory solution may help solve deadlocks that money transfers to a for‐profit operator cannot solve. The analysis highlights three main factors behind this fact. First, a customer‐owned cooperative internalizes, at least partially, the external effects generated by the project. Second, the alignment of cooperative members' preferences with those of the social planner reduces (in some cases eliminates) the distortions caused by information asymmetries. Third, cooperatives require less costly monitoring than their for‐profit counterparts. We also show that cooperatives' productive inefficiency with respect to for‐profits may emerge endogenously as a consequence of a lower pressure to compete on costs for the market.

THE COLLECTIVE DECISION PROBLEM, AND A THEORY OF PREFERENCE

This paper generalizes the "strength priority" idea of conventional majority preferences to select stronger preference patterns over weaker reverse preferences that contradict them. This generalization implies the existence of one and only one strength priority ranking that is transitive. Thus the ordering obtained can be viewed as a direct generalization of the traditional majority concept and is offered as a solution to the collective decision problem.     

ENVIRONMENTAL PROBLEMS IN POSTWAR JAPANESE SOCIETY

Abstract  We can distinguish four historical stages of environmental problems in postwar Japanese society. Historical retrospect shows that Japan was one of the worst countries concerning environmental disruption and that it experienced various issues corresponding to the change of main investment domain. Since the late 60s, residents' movements of victims pushed the business world, the national and local goverments to take more strict measures for the protection of the environment. New policy framework was defined in the beginning of the 70s. But further improvement of environment policy was not carried out under stagflation of first oil crisis. As a result of economic growth, Japanese society multiplied its demands on the ecosystem and it became a society characterized by a "separate-dependent ecosystem" and by "one-way consumption." Diseqilibrium of the power balance and defects in the decision-making process are basic social factors that have accelerated environment destruction in Japan. Despite apparent change, these social conditions continue to exist without change, and constitute an obstacle to the development of an environment-oriented technology and a transformation into a more "regenerative" society with a "self-supplying ecosystem."     

Explaining risky choices without assuming preferences

Economic theories of choice under uncertainty assume that agents act as if they have preferences which govern their choices between risky options. Theories differ as to the exact specification of the preference structure, but it is common to assume that preferences are complete and satisfy certain consistency requirements such as transitivity and monotonicity. In this paper, it is argued that there may be reason to doubt whether individuals act as if they have complete and consistent preferences over risky actions. Instead it is suggested that individuals should be thought of as actively constructing preferences through a process which I call rationalisation. It is then argued that rationalisation provides a basis for understanding certain experimentally observed anomalies which appear quite at odds with conventional theory.     

LICENSING POLICY AND TECHNOLOGY ADOPTION IN STANDARD SETTING ORGANIZATIONS

The standard setting organizations' decisions on licensing policy and standard's technological specification, and the ensuing implications for social welfare are analyzed. The author finds the conditions under which a licensing rule that grants monopoly power to the licensors whose technology is adopted in the standard can be employed by the members of the consortium (ex‐post licensing). Moreover, it is shown that the adoption of ex‐post licensing might lead to the inefficient exclusion of an efficient stand‐alone licensor. Finally, the author discusses the conditions under which a policy of ex‐ante licensing can be less efficient than ex‐post licensing. (JEL K21, L15, L24, L42)     

REFERENCE‐DEPENDENT PREFERENCES,LOSS AVERSION,AND LIVE GAME ATTENDANCE

We develop a consumer choice model of live attendance at a sporting event with reference‐dependent preferences. The predictions of the model motivate the “uncertainty of outcome hypothesis” (UOH) as well as fans' desire to see upsets and to simply see the home team win games, depending on the importance of the reference‐dependent preferences and loss aversion. A critical review of previous empirical tests of the UOH reveals significant support for models with reference‐dependent preferences, but less support for the UOH. New empirical evidence from Major League Baseball supports the loss aversion version of the model. (JEL L83, D12)
