Accidents Happen: The Effect of Uncertainty on Environmental Policy Design AgEcon
Sproul, Thomas W.; Zilberman, David.
Major externality cases are random accidents which are not adequately addressed by the deterministic environmental policy literature -­‐ that of Pigouvian taxes, abatement subsidies and cap-­‐and-­‐trade. We consider a risk-­‐neutral industry where firms control the probability and Severity of accidents by preventive and responsive choices, but asymmetric information means Government only observes outcomes. We show that even without intervention, some care will be taken, however -­‐ we identify three policies that lead to the optimal solution: strict liability, a Stochastic subsidy, and a mandatory mutual insurance scheme. The subsidy policy may be very costly to taxpayers, especially when prevention affects the probability of accident occurrence, and...

ACTUAL VERSUS STATED WILLINGNESS TO PAY: A COMMENT AgEcon
Cohen, Daniel R.; Zilberman, David.
Offering evidence from the California Irrigation Management Information System (CIMIS) and centering around Kenkel and Norris conclusions regarding “"Agricultural Producers'’ Willingness to Pay for Real-Time Mesoscale Weather Information,"” this article questions the use of growers’' hypothetical willingness-to-pay responses as the sole basis for deciding whether to invest in Mesonet, a statewide network of weather station. Survey respondents'’ lack of familiarity with a new technology and strategic behavior lead to underestimates of actual willingness to pay. Moreover, weather information has numerous agricultural and nonagricultural uses, and only sampling growers overlooks gains to other potential users. Low hypothetical willingness-to-pay responses of...

Agricultural Productivity Convergence: Myth or Reality? AgEcon
Poudel, Biswo N.; Paudel, Krishna P.; Zilberman, David.
We tested agricultural productivity convergence in the United States using the state level total factor productivity data and utilizing new estimation and cluster identification methods to identify convergence in the data. The empirical investigation did not indicate any evidence of agricultural total factor productivity (TFP) convergence at the state level. However, we found the evidence of TFP convergence at the regional level for some regions/clusters.

Biofuels: review of policies and impacts AgEcon
Janda, Karel; Kristoufek, Ladislav; Zilberman, David.
This paper provides an overview of the environmental, economical, and policy considerations related to biofuels. While the biofuel production and consumption exhibited significant increase over the first decade of the new millennium, this and further increases in biofuel production are driven primarily by government policies. Currently available first generation biofuels are with a few exceptions not economically viable in the absence of fiscal incentives or high oil prices. Also the environmental impacts of biofuels as an alternative to fossil fuels are quite ambiguous. The review of the most recent economic models dealing with biofuels and their economic impacts provides a distinction between structural and reduced form models. The review of...

Border Enforcement and Firm Response in the Management of Invasive Species AgEcon
Ameden, Holly A.; Cash, Sean B.; Zilberman, David.
This analysis presents a theoretical model of firm response to border enforcement and evaluates both the intended and unintended effects under two enforcement regimes: destruction versus treatment of contaminated shipments. The results indicate that importers may respond to increased inspection by reducing shipments and decreasing due care. In response to increased pest populations, firms may reduce shipments and increase due care, indicating that an enforcement response may not be necessary. The analysis reveals the importance of the nature of the due-care technology, as well as the relationships underlying the probability of detection, in determining the effects of enforcement.

Capturing Uncertainties in Evaluation of Biofuels Feedstocks: A Multi-Criteria Approach for the US AgEcon
Ziolkowska, Jadwiga; Simon, Leo K.; Zilberman, David.
Current research evaluating biofuels policies focuses primarily on market-economic criteria. While it is widely acknowledged that both the economic and environmental, and social aspects of biofuels policy must all be balanced with each other in the process of developing a viable biofuels policy, little progress has been made to date on evaluating these uncertain non-market relationships. In this paper, we develop a fuzzy theory holistic approach evaluating the 1st, 2nd, and 3rd generation biofuels feedstocks in meeting multiple economic, environmental and social criteria of the biofuels policies and capturing the uncertainties of evaluation processes. We use a multi-criteria approach PROMETHEE (Preference Ranking Organization Method for Enrichment...

CERTAINTY EQUIVALENT PRICES AND PRODUCER WELFARE UNDER OUTPUT PRICE UNCERTAINTY AgEcon
Tsur, Yacov; Zilberman, David.
Producer welfare indices under price uncertainty are derived using the concept of certainty equivalent prices. In this approach the marginal cost function is used instead of the ex-ante supply function; the effects of uncertainty and risk preference are captured by certainty equivalent prices. Implications for welfare evaluation are discussed.

Channeling consumption preferences for co-existence of landrace and modern varieties in-situ AgEcon
Krishna, Vijesh V.; Pascual, Unai; Zilberman, David.
The study examines the least-cost option of conserving landraces in-situ by the development of market friction instruments. The empirical examination is comprised of two closely-related studies on eggplant production and consumption sectors of India. An examination of the cost and return structure of eggplant farming in the study area reveals that the incremental farm price of eggplant products of landrace origin eclipses the yield advantage of hybrid varieties. Possibly due to the information asymmetries and other imperfections existing in this market, the price increment currently realized by the eggplant farmers is still only a fraction of consumers’ willingness to pay for landraces. This wide margin is indicative of the unexploited potential of...

Choosing Brands: Fresh Produce versus other Products AgEcon
Jin, Yanhong H.; Zilberman, David; Heiman, Amir.
This study presents a framework to analyze how uncertainty about product attributes affects consumers' WTP for brand name products over generic ones, incorporating key elements of a random utility model and product attribute models. We found that in comparison to electronics, clothing, and processed food, consumers buy brand name vegetables and fruits mainly because of quality uncertainty, and they can easily reduce uncertainty of product quality of fresh vegetables and fruits by seeing, touching, smelling, and tasting. Hence, consumers are less willing to pay for brands of fresh vegetables and fruits. However, simulation results show that brands of fresh fruits and vegetables may have a similar price premium as other products, but they lack the market...

CONSERVATION CAPITAL AND SUSTAINABLE ECONOMIC GROWTH AgEcon
Ramirez, Donna Theresa J.; Khanna, Madhu; Zilberman, David.
This paper develops an endogenous growth model which links pollution to ineffective input-use, which can be reduced through conservation capital investment. It derives the conditions under which individual preferences for environmental quality and private investment in conservation capital can lead to non-decreasing environmental quality and balanced growth in an unregulated and in a regulated regime. In the absence of regulation, balanced growth can lead to improvement in environmental quality as long as the rate of growth is low. The extent to which the growth rate is low depends upon preference for environmental quality, interest and discount rates, productivity of conservation capital, and price of the polluting input. Under an emissions tax regime,...

COOPERATIVE LABOR ALLOCATION UNDER UNCERTAINTY AgEcon
Parliament, Claudia; Tsur, Yacov; Zilberman, David.
Understanding the allocation of labor between collective and private activities within cooperatives has been an issue of interest for economists and policy makers. This paper extends existing literature by incorporating income uncertainty from both private and collective activities, and by assuming that members are risk averse. The analysis suggests a member's labor response to policy parameters can be decomposed into three components: the mean effect, reflecting the labor response under certainty or risk neutrality; the variance effect, reflecting the response to changes in risk; and the wealth effect, reflecting the response to changes in risk aversion associated with changes in wealth. The analysis demonstrates the labor response may be reversed from...

Decoupling farm policies: how does this affect production? AgEcon
Serra, Teresa; Zilberman, David; Goodwin, Barry K.; Featherstone, Allen M..
This paper studies the extent to which decoupled income support measures in agriculture can have production implications both at the extensive and intensive margins. We develop a theoretical framework that analyzes production responses of agricultural producers to apparently decoupled payments, by explicitly considering risk attitudes and uncertainty. We use farm-level data collected in Kansas to estimate the model. Technology and risk preference parameters are jointly estimated. Results show that though lump sum payments are not fully decoupled in the presence of risk and uncertainty, their effects on agricultural production are likely to be of a very small magnitude.

Differential Uncertainties and Risk Attitudes between Conventional and Organic Producers: The Case of Spanish COP Farmers AgEcon
Serra, Teresa; Zilberman, David; Gil, Jose Maria.
The growing importance of economic factors in farmers’ decision to go organic has raised interest in characterizing the economic behavior of organic versus conventional farms. Published analyses so far have not considered differential uncertainties and farmers’ risk preferences between conventional and organic practices when comparing these techniques. Our article attempts to assess this issue. We use a model of farmer decision under risk to analyze the differential values between Spanish COP organic and conventional farms and to assess the incentives for adoption of organic practices. Results show that organic and conventional farms do have different abilities to control production risk as well as different risk preferences. Organic price premiums and...

DYNAMICS OF AGRICULTURAL GROUNDWATER EXTRACTION AgEcon
Hellegers, Petra J.G.J.; Zilberman, David; van Ierland, Ekko C..
Agricultural shallow groundwater extraction can result in desiccation of neighbouring nature reserves and degradation of groundwater quality in the Netherlands, whereas both externalities are often not considered when agricultural groundwater extraction patterns are being determined. A model is developed to study socially optimal agricultural shallow groundwater extraction patterns. It shows the importance of stock size to slow down changes in groundwater quality.
