  • Heterogeneous impacts of cash transfers on farm profitability. Evidence from a randomised study in Lesotho
    Eur. Rev. Agric. Econ. (IF 2.419) Pub Date : 2020-01-20
    Prifti E, Daidone S, Pace N, et al.

    We estimate the average treatment effect (ATE) of cash transfers on farm profitability by exploiting a randomised control trial for the evaluation Lesotho’s biggest transfer program. We also explore impact heterogeneity by unpacking the ATE into group-specific parameters. We estimate conditional average treatment effects to describe how treatment effects vary with selected covariates and quantile treatment effects to illustrate the variability of effects at different outcome levels. We find that the program had sizable impacts on farm profitability, but these impacts are spread unevenly in the population. The program benefited more those with greater productive potential and had strong distributional impacts.

  • Climatic effects and total factor productivity: econometric evidence for Wisconsin dairy farms
    Eur. Rev. Agric. Econ. (IF 2.419) Pub Date : 2020-01-17
    Njuki E, Bravo-Ureta B, Cabrera V.

    This study exploits temporal and cross-sectional variation in weather and long-run climate trends to investigate their effects on farm-level productivity. Using panel data for a sample of Wisconsin dairy producers, three stochastic production frontier models are estimated and a random parameters approach is chosen as the most desirable, which accounts for stochastic observed and unobserved environmental factors. The estimated coefficients are used to decompose a multiplicative total factor productivity index that accounts for different sources of productivity growth. Annual productivity growth is estimated at 2.16 per cent, driven primarily by technical progress (1.91 per cent per annum). The average per year contribution of the other productivity components is: climate adaptation efforts −0.31 per cent; scale-mix efficiency change +0.13 per cent and technical efficiency +0.05 per cent.

  • Demand and supply of agricultural ES: towards benefit-based policy
    Eur. Rev. Agric. Econ. (IF 2.419) Pub Date : 2020-01-15
    Tienhaara A, Haltia E, Pouta E, et al.

    In order to integrate ecosystem services (ES) in designing agri-environmental policy, we investigated both the demand for, and supply of, ES from agricultural environments in Finland. Using the discrete choice experiment method, we measured citizens’ willingness to pay (WTP) for four different ES and analysed farmers’ compensation request (willingness to accept [WTA]) for producing these services. Biodiversity and water quality gathered the highest WTA of farmers, but also the highest WTP of citizens. Overall, the average WTA exceeded the WTP for almost all attributes and levels, but 20–27 per cent of farmers were willing to produce the ES with the compensation lower than citizens’ WTP.

  • Economic impacts of fall armyworm and its management strategies: evidence from southern Ethiopia
    Eur. Rev. Agric. Econ. (IF 2.419) Pub Date : 2020-01-10
    Kassie M, Wossen T, De Groote H, et al.

    This paper explores the economic implications of fall armyworm (FAW) and its management strategies by exploiting exogenous variation in FAW exposure amongst households in southern Ethiopia. We find that FAW exposure affects maize yield and sales negatively, but not consumption. Furthermore, we find evidence of crowding-in and intensification of insecticide use in response to FAW exposure. We also find suggestive evidence that existing extension service arrangements lack the capacity to deal with emerging threats such as FAW. Results imply that targeted interventions aimed at improving the effectiveness of control measures and institutional capacity would be key to reduce the adverse effects of FAW. Highlights The economic impact of fall armyworm (FAW) in southern Ethiopia assessed Fall armyworm significantly reduces maize yields and maize sales A positive correlation observed between FAW exposure and intensity of insecticide use Existing individual FAW control strategies do not significantly abate losses from FAW Improving institutional capacity is essential to control FAW

  • If smallholder farmers have access to the world market: the case of tobacco marketing in Malawi
    Eur. Rev. Agric. Econ. (IF 2.419) Pub Date : 2019-12-05
    Zant W.

    We measure the impact of a reduction in transaction costs on crop area and production of smallholder tobacco growers in Malawi. For identification, we exploit the introduction of an additional tobacco auction floor. Estimations are based on annual data by extension planning area. A 10 per cent reduction in distance to auction floor is shown to increase crop area and production around 4 and 10 per cent, respectively. Supply response weakens beyond a distance to auction floor of 60 km and runs along the intensive margin: existing tobacco growers improve productivity of cultivation. Impacts are robust for non-random placement of auction floors and several other threats. The results point to potentially large welfare benefits for smallholders if marketing infrastructure is improved and if more auction floors are introduced.

  • Measuring price discovery in the European wheat market using the partial cointegration approach
    Eur. Rev. Agric. Econ. (IF 2.419) Pub Date : 2019-12-05
    Vollmer T, Herwartz H, von Cramon-Taubadel S.

    Understanding price discovery in agricultural spot and futures markets is important for market participants and policy makers, because it can contribute to better management decisions and more informed policy debates on market regulation. Combining partial cointegration with state space modelling, we generate time-varying price discovery metrics for the European wheat market that allow for shifts in the long-run relationship. We find that the futures market dominates price discovery in terms of efficiency, but that this dominance is reduced in phases of higher price volatility. We find evidence of persistent shocks in the long-run relationship between spot and futures prices that appear to be related to variations in the quality of the wheat harvest, and to the concatenation of the futures prices.

  • Farmers’ heterogeneous motives, voluntary vaccination and disease spread: an agent-based model
    Eur. Rev. Agric. Econ. (IF 2.419) Pub Date : 2019-12-05
    Sok J, Fischer E.

    Animal health authorities responsible for effective voluntary livestock disease control need to consider the dynamic interplay between farmers’ collective behaviour and disease epidemiology. We present an agent-based model to simulate vaccination scheme designs that differ in expected adverse vaccine effects, communication strategies and subsidy levels. Specific scheme designs improve the vaccine uptake by farmers at the start of a livestock disease epidemic compared with a base scheme of minimal communication and subsidy. The results suggest that motivational mechanisms activated by a well-designed risk communication strategy are equally or more effective in increasing vaccination uptake than providing more financial compensation.

  • Analysing group contract design using a threshold public goods experiment
    Eur. Rev. Agric. Econ. (IF 2.419) Pub Date : 2019-12-23
    Bouma J, Nguyen T, van der Heijden E, et al.

    This paper presents the results of a threshold public goods game experiment with heterogeneous players. The experiment is designed in close collaboration with the Dutch association of agri-environmental farmer collectives. Subjects are recruited at a university (study 1) and a farm management training centre (study 2), the subjects of the second study most resembling the subjects in the field. The experiment consists of several treatments and each treatment has two different distribution rules, which are varied in a within-subjects manner. After subjects have experienced both, they can vote for one of the two rules: either a differentiated bonus that results in equal payoff for all, or an undifferentiated, equal share of the group bonus. In a between-subjects manner, subjects can vote for a (minimum or average) threshold or are faced with an exogenous threshold. The results indicate that exogenous thresholds perform better, possibly because the focal point they provide facilitates coordination. With regard to the two distribution rules, the results are mixed: in study 1, average contributions and payoffs are higher under the ‘equal-payoff’ rule, but there is no significant difference between the two in study 2. Overall, our results suggest that environmental payment schemes should consider cost heterogeneity in the design of group contracts, and pay explicit attention to coordination problems too.

  • Growth-oriented new agricultural ventures: the role of entrepreneurial resources and capabilities under convergence forces
    Eur. Rev. Agric. Econ. (IF 2.419) Pub Date : 2018-11-13
    Pindado E, Sánchez M.

    Using a multilevel approach, this study examines how new entrants’ resources, capabilities and context influence growth-oriented new agricultural ventures. Results indicate that growth orientation is largely self-determined. The knowledge base of the new entrants, their social ties with entrepreneurs, together with the capabilities to identify and exploit opportunities, as well as those to effectively offer new products, trigger these growth-oriented ventures. Industry contexts also influence them, as those operating in less agriculturally competitive countries have a greater probability of becoming growth-oriented, suggesting convergence forces. Lastly, results reveal that competitiveness positively moderates the relationship between product innovation capabilities and growth orientation.

  • Beliefs and preferences for food-safety policies: a discrete choice model under uncertainty
    Eur. Rev. Agric. Econ. (IF 2.419) Pub Date : 2018-11-14
    Cerroni S, Notaro S, Raffaelli R.

    Outcomes of food policies are highly uncertain. Therefore, the public’s support for these policies depends on individuals’ beliefs and the provision of scientific information. Using data collected from a discrete choice experiment survey, we explore whether new information regarding a food-safety policy influences respondents’ support, while controlling for risk and time preferences. Additionally, we examine if support depends on whether information is perceived as either good or bad news. Results from the estimation of parametric error component logit models, based on expected utility theory and rank dependent utility theory, suggest that good and bad news affects preferences and welfare measures.

  • Explaining farm structural change in the European agriculture: a novel analytical framework
    Eur. Rev. Agric. Econ. (IF 2.419) Pub Date : 2018-11-15
    Neuenfeldt S, Gocht A, Heckelei T, et al.

    In this paper, we analyse the drivers of farm structural change in the EU-27, applying a novel analytical framework in the field of agricultural economics known as the multiplicative competitive interaction (MCI) model. MCI offers a more parsimonious specification for estimating models of regional farm group shares compared to the often-applied Markov approach. The MCI framework enables farm group-specific equations, which are used to account for drivers specific to certain farm groups. The MCI framework explains farm group shares at the regional level taken from the Farm Structure Survey (FSS) using socio-economic variables from the Farm Accountancy Data Network (FADN) and other databases for the period 1989–2013. We consider eight production specialisations and two size classes at the NUTS 2 regional level. The results indicate that the past farm structure explains approximately 36 per cent of the EU farm structure variation across regions and time, followed by natural conditions (16 per cent), agricultural prices (14 per cent), macroeconomic variables (9 per cent), subsidies (7 per cent), population (6 per cent) and agricultural income (6 per cent). Further, we have run a simulation experiment where we derived elasticities of structural change with respect to time-varying variables. The structural change appears to be the most elastic with respect to income and macroeconomic variables.

  • Congestion management in protected areas: accounting for respondents’ inattention and preference heterogeneity in stated choice data
    Eur. Rev. Agric. Econ. (IF 2.419) Pub Date : 2018-11-17
    Thiene M, Franceschinis C, Scarpa R.

    Congestion levels in protected areas can be predicted by destination choice models estimated from choice data. There is growing evidence of subjects’ inattention to attributes in choice experiments. We estimate an attribute non-attendance latent class–random parameters model (LC–RPL) that jointly handles inattention and preference heterogeneity. We use data from a choice experiment designed to elicit visitors’ preferences towards sustainable management of a protected area in the Italian Alps. Results show that the LC–RPL model produces improvements in model fit and reductions in the implied rate of inattention, as compared to traditional approaches. Implications of results for park management authorities are discussed.

  • How to run an experimental auction: a review of recent advances
    Eur. Rev. Agric. Econ. (IF 2.419) Pub Date : 2019-11-29
    Canavari M, Drichoutis A, Lusk J, et al.

    In this paper, we review recent advances in experimental auctions and provide practical advice and guidelines for researchers. We focus on issues related to randomisation to treatment and causal identification of treatment effects, design issues such as selection between different elicitation formats, multiple auction groups in a single session and house money effects. We also discuss sample size and power analysis issues in relation to recent trends in experimental research about pre-registration and pre-analysis plans. We position our discussion with respect to how the agricultural economics profession could benefit from practices adapted in the experimental economics community. We then present the pros and cons of moving auction studies from the laboratory to the field and review the recent literature on behavioural factors that have been identified as important for auction outcomes.
