Communication,competition and social gift exchange in an auction for public good provision

Reverse auctions are an established policy instrument for allocating conservation contracts. While the auction mechanism has been the subject of a number of studies, less attention has been paid to the post-bidding contract phase. As contracts involving natural resource management are usually incomplete, trust becomes crucial for the effectiveness of the programme. We test the effect of communication between auctioneer and bidders on bidding behaviour and contract fulfilment using experimental economics. We combine a repeated reverse auction with an effort-level game and use a bilateral chatting tool as treatment variable. Without communication, auctioneers tended to select the lowest-priced bidders, who invested substantially less than the socially optimal level of effort when fulfilling their contract to provide the public good. Relational contracting proved important, with effort levels and profits tending to be higher when auctioneers and bidders entered into consecutive contract relationships. In the communication treatment there was no evidence of price competition, as auctioneers were more likely to accept high-priced bids. However, an overall higher price level did not lead to efficiency losses, since contractors realised higher effort levels in return, establishing a ‘social gift exchange’. Our results demonstrate the importance of trust-based relationships between the auctioneering institution and landholders.     

Interconnection and competition among asymmetric networks in the Internet backbone market

We examine the interrelation between interconnection and competition in the Internet backbone market. Networks that are asymmetric in size choose among different interconnection regimes and compete for end-users. We show that a direct interconnection regime, peering, softens competition as compared to indirect interconnection since asymmetries become less influential when networks peer. If interconnection fees are paid, the smaller network pays the larger one. Sufficiently symmetric networks enter a Peering agreement while others use an intermediary network for exchanging traffic. This is in line with considerations of a non-US policy maker. In contrast, US policy makers prefer that relatively asymmetric networks peer.     

International joint ventures and tax competition in an integrated market

The purpose of this paper is two-fold. First, it develops a theoretical model of international joint ventures to suggest a new approach to the determination of profit allocation between the partners in the joint venture. Second, we examine the issue of tax competition between two countries for an international joint venture. We find that even in the absence of any bargaining power for the domestic firms, the foreign firm would like to give up more than half of profits to its partner. Furthermore, the foreign firm would like to locate in a country in which the partner firm is more efficient. We also find, with numerical simulations, that the domestic firm will accept the joint venture if the foreign firm's technology is significantly more superior than its own.     

Information aggregation and manipulation in an experimental market

Prediction markets are increasingly being considered as methods for gathering, summarizing and aggregating diffuse information by governments and businesses alike. Critics worry that these markets are susceptible to price manipulation by agents who wish to distort decision making. We study the effect of manipulators on an experimental market, and find that manipulators are unable to distort price accuracy. Subjects without manipulation incentives compensate for the bias in offers from manipulators by setting a different threshold at which they are willing to accept trades.     

Price manipulation in an experimental asset market

We analyze in the laboratory whether an uninformed trader is able to manipulate the price of a financial asset by comparing the results of two experimental treatments. In the benchmark treatment, 12 subjects trade a common value asset that takes either a high or a low value. Only three subjects know the actual value of the asset while the market is open for trading. The manipulation treatment is identical to the benchmark treatment apart from the fact that we introduce a computer program as an additional uninformed trader. This robot buys a fixed number of shares in the beginning of a trading period and sells them again afterwards. Our main result shows that the last contract price is significantly higher in the manipulation treatment if the asset takes a low value and that private information is very well disseminated by both markets if the value of the asset is high. Finally, even though this simple manipulation program loses money on average, it is profitable in some instances.     

New products and market competition

Using a novel data set on new product introductions in U.S. manufacturing, the paper studies the relationship between new product introductions and the intensity of market competition as it is measured by industry-specific price-cost margins. New product introductions intensify market competition and depress price-cost margins. These results draw significant empirical support from a sample of five U.S. manufacturing industries. A 10 percent increase in the number of new product introductions causes price-cost margins to drop by approximately 0.5 percent. Although price-cost margins appear procyclical with respect to fluctuations in industry sales, new products make price-cost margins less procyclical and therefore, the intensity of market competition more procyclical.The author would like to thank the Board of Research at Babson College for their generous financial support.

Congestion allocation for distributed networks: an experimental study

This paper reports an experimental study of two prominent congestion and cost allocation mechanisms for distributed networks. We study the fair queuing (or serial) and the FIFO (or average cost pricing) mechanisms under two different treatments: a complete information treatment and a limited information treatment designed to simulate distributed networks. Experimental results show that the fair queuing mechanism performs significantly better than FIFO in all treatments in terms of efficiency, predictability measured as frequency of equilibrium play, and the speed of convergence to equilibrium.

Price competition in the market for business telecommunications services

We estimate a two-step control-function model that relates incumbent prices for small-business telecommunications services to the number of facilities-based entrants, cost, demand, regulatory conditions, and a correction for endogenous market structure. Results show that the price effects from entry are understated in ordinary least squares regressions. When controlling for endogeneity, prices are negatively related to the number of entrants, indicating that markets without a competitive presence could exhibit market power. These findings should prove helpful to the Federal Communications Commission and other State regulators determining the conditions under which price and other forms of regulation may be relaxed.     

Workable competition and the barrier market

To decide on interventions in a market economy politicians have to consider the temporary and intertemporal coordination achievements of market behaviour, as reflected in static and dynamic economies respectively. In this respect the barrier market concept might serve for guidance. The barrier market amounts to a formal elaboration of the workable competition concept. In this paper a model is presented of decision making of an individual supplier in a barrier market. Moreover, results are offered of analyses of competitive processes in which heterogeneous suppliers interact over time.     

Competing eco-labels and product market competition

I examine the impact of competition between eco-labeling programs in a market where eco-labels that communicate information about product's environmental quality (a credence attribute) are also strategic variables for competing firms. Specifically, I consider a dynamic setting where an industry-sponsored eco-labeling program and a program sponsored by environmental NGOs compete strategically in setting the labeling standards, before price-setting firms make strategic choices of which eco-label (if any) to adopt; adopting firms not presently meeting the labeling standards undertake costly quality improvement to comply with them. I find that the competition between eco-labeling programs may lead to the same high environmental benefit as when there exists only the NGO program. I also find that the competition may yield higher social welfare.     

Product market competition and productivity shocks

I investigate the interaction effects of competition and productivity shocks on stocks’ earnings and returns. I find that the sensitivities of earnings and returns to productivity shocks are negatively associated with competition intensity. I also find that the excess returns of productivity shocks-sorted portfolios are lower when competition intensity is high, even after controlling for known return predictors. Overall, the empirical evidence shows firms are less exposed to productivity shocks when competition is high. As such, this study provides a possible mechanism through which the structure of product markets affects stock returns.     

Ownership unbundling of natural gas transmission networks: empirical evidence

The European Commission has intensively examined the mandatory separation of natural gas transmission from production and services. However, economic theory is ambiguous on the price effects of vertical separation. In this paper, we empirically analyze the effect of ownership unbundling of gas transmission networks, considered to be the strongest form of vertical separation, on the level of end-user prices. Therefore, we apply different dynamic estimators such as system GMM and the bias-corrected least-squares dummy variable estimator to an unbalanced panel consisting of 18 EU countries over 19 years, allowing us to avoid the endogeneity problem and to estimate the long-run effects of regulation. We introduce a set of regulatory indicators as market entry regulation, ownership structure, vertical separation and market structure, as well as account for structural and economic country specifics. Among the different estimators, we consistently find that ownership unbundling has no impact on natural gas end-user prices, while the more modest legal unbundling reduces them significantly. Furthermore, third-party access, market structure and privatization show significant influence, with the latter leading to higher prices.     

Violence,access, and competition in the market for protection

We conduct a laboratory experiment to examine the performance of a market for protection. As the central feature of our treatment comparisons, we vary the access that “peasants” have to violence-empowered “elites”. The focus of the experiment is to observe how elites enforce and operate their protective services to peasants, and to observe the degree to which elites engage in wealth-destroying violence in competition amongst each other for wealth-generating peasants. We find that greater access to peasants strikingly increases violence among the elites, but with limited access the elites markedly extract more tribute from the peasants. Our findings are particularly relevant to the discussion of violence in developing countries.     

The effects of rent asymmetries in experimental auction markets

We report the results of twelve ‘double-auction’ market experiments designed to analyze the effects of asymmetric induced supply and demand configurations on the price convergence path toward a competitive equilibrium. The proposition (convergence bias) that prices tend to approach the competitive equilibrium from above (below) when consumer surplus is greater (less) than producer surplus cannot be rejected. We do, however, reject the proposition (convergence symmetry) that these convergence biases are of equal absolute magnitude. Excesses of producer over consumer surplus are found to have a more pronounced effect on the sequence of contract prices.     

A nearly optimal auction for an uninformed seller

This paper describes a nearly optimal auction mechanism that does not require previous knowledge of the distribution of values of potential buyers. The mechanism we propose builds on the new literature on the elicitation of information from experts. We extend the latter to the case where the secret information shared by the experts–potential buyers in our model–can be used against them if it becomes public knowledge.     

The role of excess capacity in determining market power in natural gas transportation markets

The approval by FERC of a regulated natural gas pipeline’s market-based rate application depends upon the availability of substitute pipelines with sufficient capacity to maintain the current transport price. But how much alternate capacity is enough? Clearly, the price will not increase when alternate pipelines have unsubscribed capacity equal to the capacity of the applicant pipeline, since the applicant’s capacity is then perfectly substitutable. And indeed, FERC has approved market-based rates when this “complete-replacement” criterion has been met. However, complete-replacement is too stringent a condition and we determine precisely how much alternate capacity suffices to keep the price from rising.
