A note on the performance measure of conservation auctions AgEcon
Latacz-Lohmann, Uwe; Schilizzi, Steven.
We argue that previous assessments of discriminatory-price conservation auctions may have systematically overestimated their performance relative to uniform-payment schemes due to an inappropriate counterfactual comparison. We demonstrate that the cost curve (and not the bid curve) is the relevant supply curve when a uniform payment is offered and provide a theoretically rigorous counterfactual based on that insight. We estimate that the performance of BushTender may have been overrated by more than 50%.

Evaluating conservation auctions with limited information: the policy maker’s predicament AgEcon
Schilizzi, Steven; Latacz-Lohmann, Uwe.
Buying environmental services from private landholders using tendering mechanisms are usually subject to a budget constraint. Auction theory has mostly focused on target-constrained auctions and is less well developed for this type of auction. This paper examines a theoretical model specifically developed for budget-constrained tenders and assesses its capacity to predict tendering performance under information limitations typical of those found in field applications. But this assessment cannot be done without complementing the model with controlled laboratory experiments. Subject to their external validity, we find that the model is able to make the correct policy recommendation when comparing the tender to an equivalent fixed price scheme, even when the...

PARTICIPATION AND LEARNING IN AUCTIONS: BIDDING DECISIONS IN EGYPTIAN OILSEED AUCTIONS AgEcon
Wilson, William W.; Wilson, Wesley W..
Auctions are common mechanisms for identifying prices and suppliers of commodities and are particularly important in agricultural marketing. Information asymmetries among bidders may be ameliorated over time through some form of learning. In this study, we incorporate prior decisions to participate, information from previous auctions, and firm-specific attributes to explain both the decision to bid and the level of the bid. Our analysis uses data from Egyptian oilseed tenders, an important market both for oilseeds and tendering. Because of the unbalanced nature of the panel data, we are able to evaluate the effects of signals received from previous tenders. We find that firms learn from previous auctions and can gain an informational advantage through...

Predicting the performance of conservation tenders when information on bidders's costs is limited AgEcon
Schilizzi, Steven; Latacz-Lohmann, Uwe.
Buying environmental services from private landholders using tendering mechanisms are usually subject to a budget constraint. Auction theory has mostly focused on target-constrained auctions and is not well developed for this type of auction. This paper examines the predictive capacity of a simple model developed for budget-constrained tenders, already used to design new conservation programs, by submitting it to controlled lab experiments. We study the capacity of the model to predict both experimental bids and the performance of the auction institution, based on the kind of limited information typically available to a conservation agency. We conclude there exists an optimal level of information on bidders’ costs, neither too large nor to small, making...
