Measuring the social costs of suboptimal combinations of policy instruments: A general framework and an example

Since most agricultural programs employ two or more policy instruments simultaneously, it is notable thai little research has attempted to find optimal instrument combinations and no research exists which evaluates the social costs (unrealized benefits) of combining instruments suboptimally. In our paper we report a simple and feasible method to find optimal policy instrument combinations, and we provide the first general, formal approach to measuring the social costs of suboptimal policy instrument combinations. Our approach is illustrated in an analysis for live major U.S. crops (corn, feed grains, wheat, rice, cotton). The simple model we employ for the illustration suggests that except lor the feed grains program, the observed programs combined policy instruments quite suboptimally. We conclude that agricultural economics research now can and should begin placing increased emphasis on studying optimal policy instrument combinations.     

RESEARCH ORIENTATIONS AND THEIR IMPLICATIONS FOR AGRICULTURAL ECONOMISTS

Division of agricultural economics research into behavioural vs. policy alternatives is proposed to reduce ambiguities implied by a positive vs normative division. The thesis is argued with reference to growth of the farm firm. A specific model is proposed. Brief comparisons are provided with alternatives in behavioural and policy applications.     

On the economics of agricultural production*

Agriculture is in the business of using ecosystem services to produce food. Examining how agro‐ecosystems function provides useful insights into the economics of agriculture. Of special interest are the presence and nature of scale effects, complementarity effects and convexity effects in ecosystem functioning. Implications for agricultural productivity and the economics of agriculture are evaluated. At the farm level, this helps to better understand the current trend toward greater specialisation. Current challenges for agricultural contracts, markets and policy are explored.     

Inducing the adoption of emerging technologies for sustainable intensification of food and renewable energy production: insights from applied economics*

Emerging advances in sustainable intensification technologies have the potential to transform land use and crop management approaches in ways that can increase resource productivity and reduce adverse environmental impacts of agricultural production. This paper describes emerging technologies that can sustainably intensify food and renewable energy production. We apply the findings from studies examining the adoption of technologies with similar stylized features to provide insights about the incentives and barriers for the adoption of these emerging technologies. We also present a landscape-based systems approach, based on welfare economics, to go beyond relying on a positive approach to explain observed adoption decisions to examining normative questions about the optimal mix, level, and location of adoption of these technologies to achieve desired societal outcomes. We conclude with a discussion of the insights from applied economics for the design of policy incentives to achieve these outcomes.     

The Potential for Cross‐Compliance in Canadian Agricultural Policy: Linking Environmental Goals with Business Risk Management Programs

Environmental cross‐compliance links agricultural program payments to producer commitments to achieve agri‐environmental policy goals. The objective of this study is to determine the feasibility of using cross‐compliance to achieve environmental goals in a Canadian policy context. While Canadian policy makers have flirted with cross‐compliance, with the exception of phosphorus regulations for Quebec hog farms, they have never adopted this approach. The potential for effective cross‐compliance depends on producer participation, producer compliance with regulations, environmental performance, and overall welfare implications. This study reviews the application of cross‐compliance in the United States and EU with regard to the potential application to Canadian agriculture. Policy options are considered which link current business risk management (BRM) programs to alternative environmental regulations (wildlife habitat preservation, nutrient management plans, and beneficial management practices for nutrient management). In general, individual Canadian agricultural support program do not provide sufficient incentives for farmers to participate in cross‐compliance. However, if support programs are combined, it is better to link programs that redistribute income with environmental programs than to link agriculture programs that already address specific market failures.     

PROBLEMS OF CHANGE IN AUSTRALIAN AGRICULTURAL ECONOMICS

There has been a low level of methodological controversy within the Australian agricultural economics profession. Johnson's 1963 paper is the most significant and in it he passed criticisms on agricultural production economists not unlike those currently being made by political economists of economics in general. These past criticisms have in the main been ignored by the Australian profession but it is suggested that they are now being pushed with renewed vigour and they can no longer be ignored. It is argued that our policy work has by and large been successful and effective except for significant areas where our methodology was of restricted usefulness. In farm management the Johnsonian strictures would seem to apply but a more charitable interpretation is provided which should meet the approval of the political economists. Our almost complete neglect of development economics must soon draw to an end and we will find that the methodologies which we have relied on heavily and fairly successfully must be augmented as we become more involved in this field. The political economics challenge should be recognized and accepted with relish because the nature of our work is changing and will continue to change in the future. We have adapted fairly well as adjustment and equity have become major policy concerns. Meeting the political economics challenge will help this process of adaptation.     

Structural and productivity change in US agriculture, 1950–1982

This paper tests whether structural change in US agriculture is an important channel to TFP growth and evaluates the relative impact of (i) public research and education policies, (ii) private R&D and market forces, and (iii) government farm programs on structural change. We specify a structural econometric model, fit it to US state aggregate data, 1953–1982, and use the associated reduced‐form model to perform counter‐factual policy simulations. The findings include: structural change is a channel to TFP growth in both crop and livestock subsector, i.e. specialization, size, and part‐time farming do impact TFP, holding other variables constant. Public R&D and education have been at least as important as private R&D and market forces for changing livestock specialization, farm size, and farmers’ off‐farm work participation over the study period, but private R&D and market forces have been relatively more important for crop specialization. Changes in farm commodity programs had little impact on farm structure over these study period. Overall, we conclude that if public R&D and education policies had been unchanged at their 1950 values over 1950–1982, major structural changes in US agriculture would have occurred anyway. The forces of private R&D and market forces were at work, including a decline in the price of machinery services and agricultural chemicals, relative to the farm wage.

Cropland expansion and grassland loss in the eastern Dakotas: New insights from a farm-level survey

The western Corn Belt region of the United States has become a hotspot for agricultural extensification and consequent land use and land cover changes. The goals of this research were to characterize geographic patterns of grassland loss resulting from cropland expansion in the eastern Dakotas, and to understand how these changes were associated with characteristics of individual farms and farm operators. We collected data on grassland conversion and other land use decisions through a mail survey of farm operators in North and South Dakota. Overall, 40% of respondents converted at least some grassland to cropland between 2004 and 2014, and the total acreage of converted grassland was equivalent to 5.1% of the surveyed farm acreage. Although most converted grassland acres (3.2% of farm acreage) were from land enrolled in the conservation reserve program (CRP), there were also substantial amounts of native grassland conversion (1.0%) and tame grassland conversion (0.9%). The total acreage of grassland conversion was more than four times larger than the acreage enrolled in CRP and other conservation programs. Different types of grassland conversion (e.g., native grassland versus CRP) were concentrated in different parts of the study region, and were spatially disjunct from the areas of highest conservation program enrollment. Larger farms were more likely than smaller farms to expand their cropland acreage and accounted for a disproportionate share of grassland conversion. Younger farm operators, higher levels of farm income, higher proportions of rented croplands, and marginal yields were also associated with cropland expansion and grassland conversion. Although CRP and other land retirement programs will remain important policy mechanisms for conservation in this region, they are not sufficient to maintain current levels of grassland cover and do not provide protection for native grasslands. Alternative conservation strategies and new agricultural policies are thus critically needed to maintain the ecosystem services provided by grasslands.     

Farmers and the U.S. Congress: rethinking basic institutional assumptions about agricultural policy

An assumption shared by most agricultural economists is that, as farm numbers decline in a democratic government, farm policy attention from rule-makers will decline as well. This assumption – despite important work to the contrary in institutional economics – is often voiced in federated governing units, especially the U.S., where constituents are locally organized and the commitment of rule-makers to nationwide policy is limited. While significant theoretical literature challenges that majoritarian view from the perspective of interest-group theory, this is the first empirical test and explanation of the behavior of rule-makers. The findings of this analysis indicate that classic majoritarian expectations are not met in the U.S. Congress. Instead, unexpectedly large numbers of legislators seek favorable policy action for farmers as distinct minorities within their districts. However, these same legislators balance their attention to farmers by also taking policy action in agriculture on behalf of other types of constituents. Legislators explain these actions as the result of their own electoral needs to satisfy vocal minorities from their political districts plus the ease with which they can marginally adjust a large base of U.S. farm programs. Thus, a kind of neo-majoritarianism emerges. These results are especially important given the growing attention to federated governance in the European Union, East Europe, in North America through free trade agreements, and with the GATT. They indicate that farmers will continue, despite shrinking numbers, to be influential in those governing structures that have historically strong farm programs and the capacity to diversify from that policy base.     

On the Relationship between the Student–Advisor Match and Early Career Research Productivity for Agricultural and Resource Economics Ph.D.s

We use a unique data set on students receiving their Ph.D.s from top-ranked agricultural and resource economics programs to investigate how the ranking of a student's dissertation advisor affects his or her early career research productivity. After controlling for program reputation, we find that the higher the relative research productivity of a student's dissertation advisor the greater the student's early career research productivity. Allowing the estimated effects of advisor rank to vary with program reputation suggests that students from lower-ranked programs working with relatively more prominent advisors outperform their peers at highly ranked programs working with less prominent advisors.     

Crop Insurance in a Political Economy: An Alternative Perspective on Agricultural Policy

Lawmakers often subsidize farmers in times of financial distress. This article models this political impulse as a constraint on government farm policy, describing how ex ante government farm insurance can deter ex post "disaster relief" and improve production incentives by countering the moral hazard that otherwise prevails. Absent ex ante government policy, ex post relief takes the form of revenue insurance, which prompts excessive entry into farm production and under-production by operating farmers. Ex ante government policy can raise economic and political welfare by buying out low productivity farmers and offering profitable farmers a combination of revenue insurance, price supports, and a program participation fee.     

Are preserved farms actively engaged in agriculture and conservation?

This study addresses the question of whether farms enrolled in land preservation programs are actively engaged in agricultural or conservation activities. Data are drawn from an original survey administered to preserved farm owners in the states of New Jersey, Maryland, and Delaware in 2011. “Actively engaged” is defined as investment in conservation projects, buildings, equipment, or irrigation since the land was preserved. Affirmative answers to the survey's investment questions range from a low of 19% for irrigation to a high of 69% for equipment. Special attention was paid to differences between lifestyle farmers and small and large commercial farmers, which are classified using the USDA typology developed in 2000. Regression analysis estimates differences in investment behavior across these groups as well as farm tenure categories, controlling for farm size, program/state location, and demographic variables. Only owners who employ tenants or managers exclusively on their land were found to invest significantly less than the largest professional farmers, and they did so across all four types of investment.This study's findings support preservation goals articulated by legislators and program administrators, because (1) agricultural and land stewardship investments appear to be widespread on preserved farms, partly due to administrators’ preference for larger parcels, (2) there is no evidence that “hobby farmers” are disproportionately attracted to farmland preservation programs – in fact the opposite seems to be true – while those that exist in our sample behave similarly to the largest commercial farmers, (3) although tenant farming is associated in the sample with lower rates of investment, it is less common on preserved farms than on all farms in the three study states. The matter of land tenure, highlighted in this as in other studies, has not yet become a primary focus of either farm-behavioral research or state agricultural policy.     

Stop and Go Agricultural Policies with a Land Market

This article studies the design of farm policy in the presence of asymmetric information about farmers' productivity, a government objective to insure farmers a minimum "parity" income, an endogenous land rent, and diminishing returns on alternative (nonprogram crop) land uses. In this setting, acreage set asides are never part of an optimal farm policy, although compensated acreage limits are. When there are new farmer entrants who cannot be excluded from farm programs, optimal policy takes the form of a pure voluntary acreage limitation—or "buyout"—program in which high-cost producers participate and low-cost producers do not.     

Factors influencing participation in the Nova Scotia Environmental Farm Plan Program

There is growing interest in Nova Scotia's Environmental Farm Plan (NS EFP) program among farmers and policy makers because of several reasons. First, effectiveness of standardized or uniform beneficial management practices in mitigating the negative environmental impacts from agriculture is limited by inherent heterogeneities in agricultural production systems. In addition, there is heightened interest in farmers generating ecological goods and services to society. This study investigates the determinants of participation in the NS EFP program. A discrete choice model of NS EFP participation was applied to a sample of 83 farmers (representing a 31% response rate). To increase relevance of the study to program administrators, the study also examined farmers’ use of various channels and sources of information on farm conservation practices. The most used sources of information on farm conservation practices include a mix of interpersonal sources and government agencies. Although online information (especially those available for free) appears to be gaining popularity in usage, overall, electronic and computer channels of information (especially radio and television) were used less compared with traditional channels of communicating farm conservation information (such as newsletters and agricultural magazines). Regression analysis suggests that farm characteristics (i.e., farm type, farm size, farm income) and farmer capacity variables (i.e., specialized training and knowledge from EFP program information sessions and workshops, and on-farm stewardship demonstrations) were significant determinants of environmental farm planning.     

THE POLITICAL ECONOMY OF AGRICULTURAL POLICY REFORM IN THE EUROPEAN COMMUNITY AND AUSTRALIA

A political-economy framework is used to explore the differences which have been observed in the pace of agricultural policy reform in the European Community and in Australia. In this framework, policy-making is endogenous in comparison with its exogenous position in applied welfare economics. It is shown that the institutional aspects of the policy process, the power of the farming lobby, and the economic philosophy of governments are important determinants of the extent of income re-distribution and of moves towards the use of more efficient instruments of income redistribution. It is argued that the degree to which politicians are captured by the farming lobby, and the extent to which they support transparency in policy-making, determine whether fundamental reforms are feasible. From this analysis, it is concluded that the pace of reform of the Common Agricultural Policy will continue to lag behind that in Australia.     

Ranking farms with a composite indicator of sustainability

The assessment of sustainability at farm level has been growing in popularity over the last few years. This article contributes to this line of research by building up composite indicators for different facets—social, economic, environmental, and global—of farm sustainability using a methodological approach that combines data envelopment analysis (DEA) and multicriteria decision making (MCDM) methods, and assigns common weights to each individual sustainability indicator. This approach is applied to a database of 163 farms located in the Campos County, a region belonging to the dry lands of the Spanish Northern Plateau, using 12 individual indicators of sustainability. Our findings show that both economic and environmental composite sustainability indicators are positively correlated, but that this is not the case for the social indicator. We also check the influence of a set of variables on farm sustainability using bootstrapping statistical techniques, and showing that increasing farm size, membership in agricultural cooperatives and farmers’ medium and upper agricultural‐specific technical education, all exert a significant positive influence on sustainability. These results provide clues for policy makers that intend to design sustainability‐increasing structural agricultural policies.     

Judging agricultural policies: a survey

This survey provides a structured picture of 40 years of literature which uses welfare economic tools to judge agricultural policy. Challenges and developments of normative agricultural policy analysis are discussed in an easily accessible graphical framework. It is shown how the literature has gone from examining a very small discrete set of simple policies to a much broader (often continuous) set of policies that combine policy instruments simultaneously. The importance of the Pareto criterion, used to explore the limits of how government can affect welfare, is revealed. Moreover, given the importance of the objective of income redistribution in agricultural policy, agricultural economists have often departed from the purely efficiency‐oriented tradition in economics. It is shown that they have tried to incorporate equity considerations by either adding these criteria as constraints to the social welfare function, or directly incorporating these criteria in the functional form of the social welfare function.     

Policy reform and farmers' wheat allocation in rural China: a case study*

Market‐oriented policy reforms often have important effects on farm‐level grain production and utilisation decisions in developing countries. China's grain farmers are of particular interest because of China's importance in world grain markets and because of China's recent major agricultural policy advances and retrenchments. An empirical evaluation of market liberalisation among farmers located in two provinces in China on farm‐level wheat consumption, market sales and on‐farm storage during 1994 is presented. The results indicate that policymakers should account for such changes in farm household behaviour in designing and assessing the consequence of market liberalisation programs for agricultural sectors in developing countries.     

Economic Perspectives in Agricultural Systems Analysis

The paper highlights the great diversity of economic research on agricultural systems, through the presentation of selected approaches: modern farm management, farming systems research, agricultural household economics, French Africanist rural economics, and behavioral and multidisciplinary systems studies. Major differences among these studies are highlighted, in terms of research aims, organization and issues, type of 'systemic' approach followed, theoretical framework, use of formal modeling, and the role of fieldwork. Trends in popularity of the different research types are discussed. The authors recommend integrating an institutional perspective in economic research on agricultural systems and broadening the research agenda.
