This study investigates the environmental impacts of several forms of policies that offer farmers subsides in return for the adoption of conservation tillage. The policies differ as to whether the tillage practice or one of several environmental benefits is targeted. We develop an Environmental Lorenz Curve which fully represents the performance of the targeting policies, and show that this curve can be directly used to help select the optimal targeting strategy for special classes of social welfare functions. The model is applied to the state of Iowa.

In this study we attempt to understand the relationship between regional growth in population, employment, and per capita income, and farmland development in Maryland, Pennsylvania, and West Virginia. A spatial simultaneous equations model is estimated using county-level data. Results indicate that while county income growth and agricultural land value increases in neighboring counties increase the rate of farmland loss, growth in county agricultural land values, increases in agricultural land density in neighboring counties, and increases in agricultural income per farm reduce farmland losses. Farmland protection policies were not significant in reducing agricultural land development. This approach, focused on regional growth, provides insight into linkages between growth and agricultural land development that can potentially enhance land use planning.

Major increases in energy prices since 1973 have raised considerable interest in the effect of a continuation of these increases on interregional competition. There is speculation in the Northeast that a general increase in energy prices will cause agricultural production to shift closer to the consumers. This production shift supposedly will lead to self-sufficiency in many products which were once grown in the Northeast and are now largely imported from other regions. This paper uses a simple interregional trade model to estimate the possible impact of higher energy prices on interregional competition, and on the Northeast in particular. It does this by assuming values for the relevant variables in the model and estimating the changes in the system. A range of values are used to estimate the sensitivity of the conclusions to the assumptions.

This paper provides a decomposition of output growth among olive-growing farms in Greece during the period 1987–1993 by integrating Bauer's (1990) and Bravo-Ureta and Rieger's (1991) approaches. The proposed methodology is based on the use of self-dual production frontier functions. Output growth is attributed to the size effect, technical change, changes in technical and input allocative inefficiency, and the scale effect. Empirical results indicate that the scale and the input allocative inefficiency effects, which were not taken into account in previous studies on output growth decomposition analysis, have caused a 7.3% slowdown and a 11.0% increase in output growth, respectively. Technical change was found to be the main source of TFP growth while both technical and input allocative inefficiency decreased over time. Still though, a 56.5% of output growth is attributed to input growth.

The Uruguay Round Agreement on Agriculture (URAA) put in place a set of rules that may, in the future, have significant effects on the conditions for market access for agricultural products. Bound tariffs replaced non-tariff barriers in most cases, and rules facing exporters are now more transparent. In addition, minimum access commitments were made through the use of import quotas, with a lower tariff for imports within the quota. Although agriculture is now integrated into the multilateral trading system, most commentators agree that the URAA did little actually to liberalize agricultural trade. Bound out-of-quota tariffs remain very high while quotas have resulted in the institutionalization of rents for specific countries and firms or state trading enterprises, thereby potentially increasing resistance by these stakeholders to any trade liberalization initiatives.

We use nonparametric production function methods to decompose farm-level labor productivity growth into components attributable to efficiency change, technical change, and factor intensity. The estimation is accomplished using balanced panel data drawn from the Kansas Farm Management Association for the period 1993 to 2007. We find that labor productivity growth is primarily driven by factor intensity and technical change. Efficiency change is declining with increasing productivity growth, and technical change is not Hicks-neutral and occurs at high levels of factor intensity, suggesting that innovation is embodied in factor intensity.

The hedonic approach has been advanced recently as an important tool for assessing the value of non-market environmental attributes. In its most usual form, the method involves an attempt econometrically to capture differential prices for homes attributable to variations in the environmental characteristic. This technique has been applied with success for a variety of attributes – most notably the study of air pollution. However, the case studies reported here for water quality valuation were much less successful. We advance several reasons why the hedonic approach may be ill-suited to measuring the value of water quality.

The first-difference version of a source-differentiated almost ideal demand system is used to estimate demand for Ivorian rice imports. The results indicate that Thailand will benefit most from an expansion of imports of luxury rice and broken rice products. Vietnam will gain from growth in the market for standard rice. The results also suggest that adoption of a new 35 percent tariff policy to protect the domestic industry will not be enough to improve social welfare in Côte d'Ivoire in spite of increased production value.

Centralized, off-farm compost facilities were evaluated as a disposal option for poultry litter. Disposal fees to growers were required to develop an economically feasible facility for a private investor. The potential for a compost facility to compete with current litter alternatives depends upon development of compost markets comparable to urban areas along with a depressed market price for litter. Given disposal fees and uncertainty associated with market development, further expansion of land application and cattle feeding disposal alternatives is recommended.

Tariff rate quota administration and implementation are empirically evaluated for the fourteen developing countries notifying the WTO of the use of TRQs. FAO trade data, UNCTAD data on applied tariffs and the WTO notifications permit us to assess underfill of quotas, discrimination among exporters, use of state trading as an implementation mechanism, and the extent of protection under these TRQs. Substantial liberalization was found, generally due to use of low MFN tariffs rather than through TRQs permitting greater market access. High tariff bindings and endogenous quotas allow these countries to pursue flexible trade regimes within their WTO commitments.

The study examines the impacts of implementing mandatory country of origin labeling (COOL) on producer and consumer welfare in the U.S. meat industry. The equilibrium displacement model developed in this study includes twenty-nine equations representing retail-, processing-, and farm-level equilibrium conditions for the beef, pork, and chicken industries. Unlike previous studies, the model allows trade between domestic- and foreign-origin products and considers the imperfectly competitive market structure of meat processers. Empirical results show that without a significant increase in domestic meat demand, producers are not expected to benefit from the mandatory COOL implementation. Results of a sensitivity analysis indicate that consumers tend to bear more COOL costs than producers, as the own-price elasticity becomes more inelastic, and that producers’ benefits increase as the elasticity of domestic demand becomes more elastic with respect to the price of imported products. The existence of market power in upstream and downstream markets of processors negatively affects both consumer and producer surplus. One implication of our findings is that U.S. beef and pork producers’ promotion and advertising programs would be successful in expanding domestic demand when the programs make the own-price elasticity of domestic demand more inelastic and the cross-price elasticity of domestic demand more elastic with respect to import price.

This paper develops and applies a methodology to assess the accuracy of historical loss-cost rating procedures, similar to those used by the U.S. Department of Agriculture's Risk Management Agency (RMA), versus alternative parametric premium estimation methods. It finds that the accuracy of loss-cost procedures leaves much to be desired, but can be markedly improved through the use of alternative methods and increased farm-level yield sample sizes. Evidence suggests that the high degree of inaccuracy in crop insurance premium estimations through historical loss-cost procedures identified in the paper might be a major factor behind the need for substantial government subsidies to keep the program solvent.

Using farm data from three dairy-dependent communities in Wisconsin, this study addresses the question: Do small farms spend more locally than large farms? The work develops a theoretical model of farm cost functions with transaction costs varying between local and distant input sources. This model is then tested econometrically, describing farm costs and where they were spent as a function of transaction/search costs and farm characteristics. The results suggest that scale does matter to farm spending patterns.

A survey of household decision-makers and an analysis of their garbage was used to suggest factors affecting the weight of household contributions to municipal solid waste. Iterative regression was used to build a model from the data that is hypothesized to explain garbage weight. Food expenditure, environmental attitude, consumption of soft drinks in plastic bottles, and cats in the household were significant for all households. Self-sufficiency and energy-conscious behavioral scales also affected the subgroup with female householders having an educational level of high school graduation or less.

It is a generally known statistical fact that the mean of a nonlinear function of a set of random variables is not equivalent to the function evaluated at the means of the variables. However, in dichotomous choice contingent valuation studies a common practice is to calculate an overall mean (or median) by integrating over offer space (numerically or analytically) an estimated logit or probit function in which sample mean values for the concomitant variables are used. We demonstrate this procedure to be incorrect and we statistically test the procedure against the correct method for nonlinear models. Using data resulting in a well-behaved logit model, we reject the hypothesis of congruence between the two means. Such a finding should be considered in future single response dichotomous choice CVM studies, particularly when aggregation is of interest.

This paper analyzes the determinants of variation across industries in levels of intra-industry trade (IIT) for a sample of thirty-six U.S. processed food and beverage industries in 1987, previous studies of intra-industry trade having focussed on industry characteristics in the manufacturing sectors. The determinants predicted by IIT theory are measures of product differentiation, economies of scale, and imperfect competition; the results of this analysis indicate that IIT variation across the food and beverage industries is positively related to product differentiation, economies of scope, and similarity of tariff barriers among trade partners, but negatively related to industry concentration.

Stochastic dominance analysis of five crop rotations using twenty-one years of experimental yield data returned results consistent with Pennsylvania cropping practices. The analysis incorporated yield risk, output price risk, and rotational yield effects. A rotation of two years corn and three years alfalfa hay dominated for approximately risk neutral and risk averse preferences, as did participation in government programs under the 1990 Farm Bill. Crop rotation selection appeared to impact net revenues more than the decision to participate in government programs.

Selfishness of preferences alone will not support the coordination necessary for the industrialization of the food system. Social capital relationships of mutual sympathy (caring) yield socio-emotional goods that are important in the more personal business world of evolving incomplete contracts and alliances involving input suppliers, processors, and labor. Relationships are also critical when consumers are buying image as well as physical products. Management and policy alternatives constitute investment in social capital that can affect opportunism, risk, loyalty, and trust.

This paper demonstrates how corner solutions raise difficulties for the specification, estimation, and use of incomplete demand systems for welfare measurement with disaggregate consumption data, as is common in the outdoor recreation literature. A simple analytical model of consumer behavior is used to elucidate the potential biases for welfare measurement arising from modeling the demand for M goods as a function of M + N prices (N > 1) and income when individuals do not consume all goods in strictly positive quantities. Results from a Monte Carlo experiment suggest that these biases can be substantial for large-scale policy shocks when prices are highly correlated.

In 2009, West Virginia enacted an Alternative and Renewable Portfolio Act (APRA) to broaden its energy use for electricity beyond coal. A choice experiment survey was conducted to assess West Virginians’ willingness to pay (WTP) for 10 percent of electricity generated from wind energy versus natural gas. Results showed that residential consumers preferred electricity generated from wind, with annual per-capita WTP averaging from $19.25 to $26.75. Given the subsequent repeal of the APRA in 2015, we propose implementation of a voluntary green pricing program as an alternative policy to increase the share of renewable energy in West Virginia's energy portfolio.
