Entrepreneurship and Team Participation: An Experimental Study

Entrepreneurs are surprisingly unlikely to have partners. In spite of the obvious advantages to forming partnerships, only a small minority of entrepreneurs (less than 10%, excluding family businesses) have partners. A number of possible explanations exist for this puzzling phenomenon, including an inability to locate suitable partners, fear of free-riding by partners, and a preference for not working in groups. Utilizing a diverse subject population with a high proportion of active entrepreneurs, we use a team production experiment to study whether entrepreneurs prefer to work alone or in a team. The data indicate that entrepreneurs, while no more likely to free-ride on their teammates, are substantially less interested in joining teams. This suggests that efforts to encourage partnership among entrepreneurs may run contrary to the preferences of this group.

Speculation and Demand Reduction in English Clock Auctions with Resale

Many auctions are followed by a resale market which occurs when the winner of the auction resells the item won to one of the participants from the original auction. The existence of such transactions may initially appear counter intuitive. However, this paper will show that active inter-bidder resale results from payoff maximizing decisions in the auction that take into account the incentives of a resale opportunity. Specifically, I examine how the existence of an inter-bidder resale opportunity impacts bidder behavior in an English clock auction, and to what extent altering the bargaining power of the final buyer and reseller in the resale market determines the strategies followed in the initial auction, in an attempt to understand the existence of these inter-bidder transactions. Theoretical and behavioral analysis is used to develop hypotheses of speculation (bidding above value) and demand reduction (bidding below value) which are directly tested in a controlled experimental setting. While value bidding is a dominant strategy in a standard English clock auction without resale, when resale is allowed, this theoretical claim is weaker. Demand reduction is observed when the bargaining power is shifted to the final buyer in resale and when the bargaining power is shifted toward the reseller, speculation is observed. The revenue achieved in the initial auction depends on the behavior observed in the auction. Regardless of bargaining power, revenue is shown to decrease below what would have been earned in an English auction without resale due to demand reduction. When the reseller has the bargaining power, and speculation is observed, this loss in revenue is somewhat mitigated by increased speculation.

Demand Reduction in Multi-Object Auctions with Resale: An Experimental Analysis

We analyze the effects of different resale mechanisms on bidders’ strategies in multi-object uniform-price auctions with asymmetric bidders. Our experimental design consists of four treatments: one without resale and three resale treatments that vary the information available and the bargaining mechanism in the resale market. The presence of a resale market induces demand reduction by high-value bidders and speculation by low-value bidders, thus affecting the allocation of the objects on sale. The magnitude of these effects, however, depends on the form of the resale market. Features of the resale market that tend to increase its efficiency result in lower auction efficiency and seller’s revenue. We also show that, without resale, asymmetry among bidders reduces demand reduction.

The Impact of Beliefs on Effort in Telecommuting Teams

Telecommuting policies have been increasingly adopted by employers. The benefits of telecommuting from the employers perspective include direct cost-saving from not having to house employees in an office and indirect cost-saving through reduced turnover associated with increased employee satisfaction. The downside is the perceived opportunity for shirking outside of the traditional workplace, a problem which is potentially exacerbated if employees are placed into telecommuting teams. Using a controlled experiment which randomly assigned subjects to participate in the laboratory (non-telecommuters) or to participate online in a location of their choice (telecommuters), we directly test whether telecommuters are more likely to free ride when in teams and whether or not the locational composition of the team influences this outcome. We find no evidence of free-riding in teams for either telecommuters or non-telecommuters. We also find that variation in output when a worker is paired in a traditional team versus a telecommuting team can be attributed to the beliefs subjects have about their teammates productivity. The last result leads directly to policy implications for managers.

Efficiency in Auctions with (Failed) Resale

We analyze how the possibility of resale affects efficiency in multi-object uniform-price auctions with asymmetric bidders using a combination of theory and experiments. The resale market is modeled as an unstructured bargaining game between auction bidders. Our experimental design consists of four treatments that vary the (exogenous) probability that bidders participate in a resale market after the auction. In all treatments, the possibility of resale increases efficiency after the auction, but it also induces demand reduction by high-value bidders during the auction, which reduces auction efficiency. In contrast to what is usually argued, resale does not necessarily increase final efficiency. When there is a low probability of a resale market, final efficiency is actually lower than in an auction without resale.
