Grain price adjustment asymmetry: the case of cowpea in Ghana AgEcon
Langyintuo, Augustine S..
Patterns in price adjustment in response to information are important to market practitioners. This study looks at cowpea real wholesale price adjustment patterns in Bolgatanga, Wa, Makola and Techiman markets in Ghana. Using Techiman as the central market, a threshold autoregressive test for asymmetric price adjustment rejected the null hypothesis of symmetric adjustment for only the Bolgatanga-Techiman price series. An autoregressive conditional heteroskedastic regression indicates that wholesalers in Bolgatanga market respond differentially to price signals from Techiman than those in the other two markets. This suggests that policies targeting cowpea traders must recognize the differential responses by wholesalers to information.

When Promoters Like Scalpers AgEcon
Karp, Larry S.; Perloff, Jeffrey M..
If a monopoly supplies a perishable good, such as tickets to a performance, and is unable to price discriminate within a period, the monopoly may benefit from the potential entry of resellers. If the monopoly attempts to intertemporally price discriminate, the equilibrium in the game among buyers is indeterminate when the resellers are not allowed to enter, and the monopoly's problem is not well defined. An arbitrarily small amount of heterogeneity of information among the buyers leads to a unique equilibrium. We show how the potential entry of resellers alters this equilibrium.

Lack of Credibility in Food Markets - Driving Medium Quality Food Out of the Market AgEcon
Christensen, Jan; Graversen, Jesper T..
Some food markets are dominated by high quality and standard quality segments, whereas medium quality products are almost absent. A modeling framework with asymmetric information regarding true quality of the products and the resulting lack of consumer confidence is presented. Uncertainty regarding the quality of alleged medium quality products provides certain consumer groups to divert consumptions away from medium quality to either standard or high quality products. These countervailing incentives explain the missing medium quality products. Empirical examples are given to motivate the model.

Consumers’ Willingness to Pay for New Genetically Modified Food Products: Evidence from Experimental Auctions of Intragenic and Transgenic Foods AgEcon
Colson, Gregory; Huffman, Wallace E..
Early GM traits were obtained by transferring genes across species, largely from soil bacteria. Part of the consumer resistance to them has been their transgenic nature. Recently, breakthroughs have occurred using intragenic bioengineering where genes are moved long distances within a specie, for example in potato, and without antibiotic markers. The objective of this research is to assess consumers’ acceptance and willingness to pay (WTP) for new intragenic fresh potato, tomato, and broccoli with higher levels of antioxidants and vitamin C, which are consumer traits. To elicit consumer valuations, a new series of experimental auctions were conducted in 2007 that built upon methodology developed in our earlier research. WTP was assessed in a multi-round...

Creating Incentives for Micro-Credit Agents to Lend to the Poor AgEcon
Aubert, Cecile; de Janvry, Alain; Sadoulet, Elisabeth.
Microfinance institutions (MFIs) have introduced incentive pay schemes for their credit agents to induce information acquisition on borrowers. Bonuses linked to repayment are efficient for profit-oriented MFIs but insufficient for nonprofit MFIs trying to reach very poor borrowers, when repayment and wealth are positively correlated. We show that no incentive scheme is consistent with this (non-verifiable) objective: Random audits on the share of very poor borrowers selected by the agent become necessary. Under the optimal contract, non-profit MFIs generally maximize the number of poor borrowers it services by crosssubsidization between very poor and less poor borrowers.

Adverse Selection in the Environmental Stewardship Scheme: Evidence in the Higher Level Stewardship Scheme? AgEcon
Quillerou, Emmanuelle; Fraser, Rob W.; Fraser, Iain.
The Environmental Stewardship Scheme provides payments to farmers for the provision of environmental services based on foregone agricultural income. This creates a potential incentive compatibility problem which, combined with an information asymmetry on farm land heterogeneity, could lead to adverse selection of farmers into the Scheme and therefore reduced cost-effectiveness of the Scheme. This reduced cost-effectiveness would be represented by a systematic overpayment of farmers for the land enrolled into the Scheme, compared to the opportunity cost of production. This paper examines the potential adverse selection problem affecting the higher tier of the Environmental Stewardship, the Higher Level Stewardship, using a principal agent framework combined...

On the Accuracy of Regulatory Cost Estimates AgEcon
Harrington, Winston; Morgenstern, Richard D.; Nelson, Peter.
This study compares ex ante estimates of the direct costs of individual regulations to ex post assessments of the same regulations. Our review of more than two dozen environmental and occupational safety regulations indicates that ex ante estimates of total (direct) costs have tended to exceed actuals. We find this to be true of 12 of the 25 rules in our data set, while for only 6 were the ex ante estimates too low. The overestimation of total costs is often due to errors in the quantity of emission reductions achieved by the rule which, in turn, suggest that the rule's benefits may also be overestimated. The quantity errors are driven by both baseline and compliance issues. At least for EPA and OSHA rules, overestimation of per-unit abatement costs occurs...

Current factors of insurance in agriculture AgEcon
Bokusheva, Raushan; Heidelbach, Olaf.
This discussion paper is our response to numerous questions and the desire of our counterparts from the CIS countries to receive more up-to-date information about insurance in agriculture. Accordingly, we have tried to shed light on the main aspects of insurance as one tool of risk management in agriculture. Thus, our purpose is to give the reader information on principles and potential of insurance, its main problems and possible solutions. Additionally, this paper provides a comparative overview of the presently most widespread insurance schemes.
