CHALLENGES AND OPPORTUNITIES PROVIDED BY SEASONAL CLIMATE FORECASTS: A LITERATURE REVIEW AgEcon
Hill, Harvey S.J.; Mjelde, James W..
Use of seasonal climate forecasts is a rapidly evolving area. Effective research and application of climate forecasts require close cooperation between scientists in diverse disciplines and decision makers. Successful collaboration requires all players to at least partially understand each other's perspectives. Issues associated with seasonal forecasts, through a selected review of both physical and social sciences literature, is presented. Our hope is that the review will improve research in this area by stimulating further collaborations.

Climate Change and Individual Decision Making: An Examination of Knowledge, Risk Perception, Self-interest and Their Interplay AgEcon
Pongiglione, Francesca.
In this essay, three separate yet interconnected components of pro-environmental decision making are considered: (a) knowledge, in the form of basic scientific understanding and procedural knowledge, (b) risk perception, as it relates to an individual’s direct experience of climate change and (c) self-interest, either monetary or status-driven. Drawing on a variety of sources in public policy, psychology, and economics, I examine the role of these concepts in inducing or discouraging pro-environmental behavior. Past researches have often overemphasized the weight of just one of those variables in the decision making. I argue, instead, that none of them alone is capable of bringing about the behavioral change required by the environmental crisis. Evidence...

Consumer Welfare and the Loss Induced by Withheld Information: The Case of BSE in Italy AgEcon
Mazzocchi, Mario; Stefani, Gianluca.
The paper develops a measure of consumer welfare losses associated with withheld information about BSE linkage with vCJD. food safety. The Cost of Ignorance (COI) is measured by comparing the utility of the informed choice with the utility of the uninformed one, under condition of improved information. Unlike previous work, based on a single equation demand model, the measure is obtained retrieving a cost function from a dynamic Almost Ideal Demand System. The results indicate that Italian consumers bore a significant loss because of the delayed release of information.

Crop biodiversity repercussions of subsidized organic farming in Greece AgEcon
Nastis, Stefanos A.; Michailidis, Anastasios; Mattas, Konstadinos.
This paper analyzes the impact of CAP financial assistance on crop biodiversity under uncertainty. A stochastic production function is employed and estimated to assess whether risk-averse farmers hedge risk by diversifying their portfolio of crops, thus increasing crop biodiversity. The model is applied to farm-level data of organic crop farms in Greece. Organic farming financial assistance poses a double-edged sword: even though it is considered agrobiodiversity enhancing as a cultivation method, subsidizing it can become agrobiodiversity reducing, since farmers may select to cultivate only the subsidized crops. The study shows that risk aversion leads to crop biodiversity conservation. However, providing CAP financial assistance on certain crops appears...

EFFECTS OF POLICY INSTRUMENTS ON FARM INVESTMENTS AND PRODUCTION DECISIONS IN THE SPANISH COP SECTOR AgEcon
Kallas, Zein; Serra, Teresa; Gil, Jose Maria.
Our paper assesses the impacts of the partially decoupled (PD) scheme, implemented during the 1990s and first half of the 2000s in the framework of the Common Agricultural Policy (CAP), on on-farm investment as well as on other production decisions. The Spanish COP sector was taken as a case study due to its economic and political relevance. The empirical analysis is applied on farm-level data from the Farm Accountancy Data Network (FADN), observed from 2000 to 2004, based on. We use a reduced-form application of the dual model of investment under uncertainty and a system of censored and non censored equations is estimated. PD payments are found to increase short-run production and to generate a statically significant increase in the investment in farm...

Estimating State-Contingent Production Functions AgEcon
Rasmussen, Svend; Karantininis, Kostas.
The paper reviews the empirical problem of estimating state-contingent production functions. The major problem is that states of nature may not be registered and/or that the number of observation per state is low. Monte Carlo simulation is used to generate an artificial, uncertain production environment based on Cobb Douglas production functions with state-contingent parameters. The parameters are subsequently estimated based on different sizes of samples using Generalized Least Squares and Generalized Maximum Entropy and the results are compared. It is concluded that Maximum Entropy may be useful, but that further analysis is needed to evaluate the efficiency of this estimation method compared to traditional methods.

Evaluating the Impact on Market Performance of Investments in Market Information Systems: Methodological Challenges AgEcon
Staatz, John M.; Kizito, Andrew M.; Weber, Michael T.; Dembele, Niama Nango.
Evaluating the impact on market performance of investments in agricultural market information systems (MIS) face several methodological challenges. These fall into two broad categories: (a) defining the dimensions of market performance to measure (which is a function of whom the MIS is designed to serve) and identifying reliable indicators of those performance dimensions, and (b) identifying the causal effects of the MIS. The determination of causal effects in turn requires establishing a credible baseline, measuring “treatment effects” (i.e., the effects on economic behavior of receiving improved information from an MIS), dealing with problems of endogenous placement of treatment, and interpreting the validity of stakeholders’ statements and...

Experimental Evidence on Willingness to Pay for Red Meat Traceability in the United States, Canada, the United Kingdom, and Japan AgEcon
Dickinson, David L.; Bailey, DeeVon.
We employed Vickrey auctions to generate willingness-to-pay (WTP) data for red meat traceability and related product characteristics with comparable experimental auctions in the United States, Canada, the U.K., and Japan. The results show that subjects are willing to pay a nontrivial premium for traceability, but the same subjects show even higher WTP for traceability-provided characteristics like additional meat safety and humane animal treatment guarantees. The implication is that producers might be able to implement traceable meat systems profitably by tailoring the verifiable characteristics of the product to consumer preferences.

Food Scares and Consumer Behaviour: A European Perspective AgEcon
Mazzocchi, Mario; Lobb, Alexandra E.; Traill, W. Bruce.
In this paper a consumer food choice model based on the Theory of Planned Behaviour (TPB) is extended to account for risk perception and trust. The data are from a nationally representative European survey of 2 725 respondents from five countries, France, Germany, Italy, Netherlands and the United Kingdom. The model relates the intention to purchase chicken in an extended TPB framework, which incorporates risk perceptions, and trust in alternative sources of food safety information. This model was run for two behaviours of interest: the standard likelihood of intention to purchase and the likelihood of intention to purchase conditional on news about a salmonella incident. The model has good predictive power and shows distinct country differences. Only in...

Governmental Learning as a Determinant of Economic Growth AgEcon
Grusevaja, Marina.
Systemic economic transition is a process of determined radical institutional change, a process of building new institutions required by a market economy. Nowadays, the experience of transition countries with the implementation of new institutions could be reviewed as a method of economic development that despite similar singular steps has different effects on the domestic economic performance. The process of institutional change towards a market economy is determined by political will, thus the government plays an important role in carrying out the economic reforms. Among the variety of outcomes and effects the attention is drawn especially to economic growth that diverges significantly in different post-transition countries. The paper attempts to shed...

Harmful Signaling in Matching Markets AgEcon
Kushnir, Alexey.
Some labor markets have recently developed formal signalling mechanisms, e.g. the signalling for interviews in the job market for new Ph.D. economists. We evaluate the effect of such mechanisms on two-sided matching markets by considering a game of incomplete information between firms and workers. Workers have almost aligned preferences over firms: each worker has “typical” commonly known preferences with probability close to one and “atypical” idiosyncratic preferences with the complementary probability close to zero. Firms have some commonly known preferences over workers. We show that the introduction of a signalling mechanism is harmful for this environment. Though signals transmit previously unavailable information, they also facilitate information...

ON ADAPTATION TO CLIMATE CHANGE AND RISK EXPOSURE IN THE NILE BASIN OF ETHIOPIA AgEcon
Di Falco, Salvatore; Veronesi, Marcella.
This study investigates the impact of climate change adaptation on farm households’ downside risk exposure (e.g., risk of crop failure) in the Nile Basin of Ethiopia. The analysis relies on a moment-based specification of the stochastic production function. We estimate a simultaneous equations model with endogenous switching to account for the heterogeneity in the decision to adapt or not, and for unobservable characteristics of farmers and their farm. We find that (i) climate change adaptation reduces downside risk exposure, i.e., farm households that implemented climate change adaptation strategies get benefits in terms of a decrease in the risk of crop failure; (ii) farm households that did not adapt would benefit the most in terms of reduction in...

Optimal Contracting for Cattle Feeding: An Assessment of Climatic Conditions AgEcon
Rahman, Shaikh Mahfuzur.
A unique approach using a biophysical growth model from the animal science literature is used to examine optimal contract cattle feeding behavior under alternative climatic conditions. The examination of incentives and outcomes in an unusually comprehensive contract parameter and behavioral space is made possible by combining simulated feedlot and carcass performance of a large set of cattle with public price and weather data. The model uniquely fits typical risk aversion levels and rationalizes existing contract types. The results show that optimal cattle feeding contract varies with climatic condition, but there is a tendency to replace cost-of-gain contracts with yardage-feed contracts as grid pricing has emerged.

Parental Response to Health Risk Information: A Lab Experiment on Evaluating Willingness-to-Pay for Safer Infant Milk Formula AgEcon
Goldberg, Isabell; Roosen, Jutta; Nayga, Rodolfo M., Jr..
Enterobacter sakazakii, a pathogen that can be found in powdered infant milk formula, can cause adverse health effects on infants. Using Vickrey auction, this study examines parents' willingness to pay (WTP) for a quality assurance label on powdered infant milk formula. The influence of ambiguity with the incidence rate information and provision of safe-handling information on WTP are also evaluated using three experiments/treatments. Results generally suggest that parents are willing to pay for quality assurance label. The mean price premium parents are willing to pay for the safer and quality assurance labelled powdered infant milk formula ranges from 61 to 133 Eurocents per 100 grams depending on the treatment. While no ambiguity effects are generally...

'Pocket and Pot': Hypothetical Bias in a No-Free-Riding Public Contribution Game AgEcon
Gubanova, Tatiana; Adamowicz, Wiktor L.; McMillan, Melville.
Hypothetical bias arises when values which people say they place on a good or service differ systematically from the values people reveal for the same good or service through actual, binding economic transactions. Studies of hypothetical bias with respect to public goods often use charitable contributions or other relatively unique goods and these studies employ a variety of mechanisms to elicit the stated and revealed values. This study proposes the inclusion of a free-rider barring random dictatorship mechanism in the standard public contribution game to investigate the issue of bias when a public good involves immediate monetary returns to subjects. Steps are taken to make the game have the look and feel of a real world trade-off between private...

The Economics of a Lost Deal AgEcon
Hourcade, Jean-Charles; Ghersi, Frederic.
This paper examines compromise spaces between competing perspectives on four key climate change issues: costs, level of domestic action, environmental integrity, and developing world involvement. Based on extensive simulations of a model integration tool, SAP12 (Stochastic Assessment of Climate Policies, 12 models), the analysis considers options for fine-tuning the Kyoto Protocol, such as concrete ceilings or levies on carbon imports; restoration payments to be made on excess emissions; credits for sequestration activities in Annex B countries; and others. It shows the critical importance of the baseline against which the performance of each tool has to be assessed in the absence of direct economic penalties for noncompliance. The restoration payment...

The impacts of thresholds on risk behavior: What's wrong with index insurance? AgEcon
Osgood, Daniel E.; Shirley, Kenneth E..
Almost universally, implementers of index insurance for low income households have chosen to embed insurance with other interventions designed to improve productivity, with the insurance used almost entirely to make the other interventions possible. A common example is to use the insurance to allow farmers to have access to loans by reducing the probability of weather related defaults. A bundled loan/insurance implementation with overwhelming take-up rates had low insurance take-up rates when researchers unbundled the package, covering the loan default risk, so that the loans could be available without requiring insurance. If low income farmers are highly risk averse, why do they place so little value on risk reducing insurance once their access...
