Authors:Böcker T; Britz W, Möhring N, et al. Pages: 371 - 402 Abstract: We aim to contribute to a more informed discussion of the economic and environmental effects of a glyphosate ban in European agriculture. As real-world observations of weed control under a glyphosate ban are not available, we develop a normative modelling approach based on damage abatement functions considering production risk and farmers’ risk preferences. Different sources of risk are included by incorporating uncertainty of both attainable yield level and weed pressure. Results for a case study of silage maize cultivation in 377 municipalities in North Rhine-Westphalia, Germany, show that a glyphosate ban causes a shift towards more mechanical weed control, but not to more pronounced use of selective herbicides. The ban slightly reduces net profits and yields, leads to a significant reduction of the overall toxicity of pesticide use, but increases energy consumption of the agricultural system. The magnitude of these effects is found to be critically dependent on output price levels and yield expectations.

Authors:Mohan S. Pages: 403 - 437 Abstract: The effect of risk aversion on farmer certification to standards is analysed by considering an industrial organisation model of differentiated exchange of high- and low-quality products between farmers, intermediaries and consumers. In the presence of uncertainty over the proportion of their produce that will be rejected by consumers, a relatively risk-averse population of farmers in an export enclave will tend to adopt a high-quality standard in greater numbers. When some producers export and some produce for domestic markets, however, relatively risk-averse farmers find the low-quality standard most appealing. The relationship between risk and standard adoption is affected by market conditions including the rejection rates of produce, profit margins and the extent of demand differentiation between the two varieties.

Authors:Meunier G. Pages: 438 - 466 Abstract: This article analyses the trade-off between yield and farmed area when a valuable species is affected by agricultural practices. It revisits, from an economic perspective, the ‘land-sparing versus land-sharing’ debate. We show that the optimal yield is either increasing or decreasing with respect to the value of the species. Land-sparing and land-sharing are not necessarily antagonistic; for a sufficiently elastic demand function, both the optimal yield and the farmed area decrease with the public value of the species. A general assessment of a second-best policy is performed, and several particular policies are considered.

Authors:Chatzimichael K; Christopoulos D, Stefanou S, et al. Pages: 467 - 498 Abstract: This paper develops a consistent theoretical framework for measuring irrigation water effectiveness and its impact on productivity growth rates by assuming a smooth transition process from traditional to modern irrigation technologies among individual farmers. The econometric model is based on a two-stage estimation procedure incorporating the transition process within a primal TFP decomposition framework. An empirical investigation addresses a panel of 56 small-scale greenhouse farms in Crete, Greece during the 2010–2013 period. The results indicate that technical change driven by irrigation water technology improvement contributes significantly to total factor productivity growth. Further, the impacts of specific climatic and soil conditions do not allow farmers to fully explore the potential of the new irrigation technology delaying adoption rates.

Authors:Byrne J; Sakemoto R, Xu B. Pages: 499 - 528 Abstract: This paper extends the topical literature on the co-movement and determinants of primary commodity prices, by considering heterogeneity in commodities and time variation in the impact of fundamentals. We account for heterogeneity by employing a dynamic hierarchical factor model, which decomposes commodities into global and sectoral factors. Using a time-varying parameter factor augmented VAR model, we shock global and sector-specific factors over time. We present plausible impulse responses to demand shocks, real interest rate shocks and to elevated risks during the global financial crisis. We also identify that agricultural raw materials, food and metals respond heterogeneously to these shocks.

Authors:Lampach N; Nguyen-Van P, To-The N. Pages: 529 - 557 Abstract: Increasing consumer awareness on sustainable and healthy food choices has given rise to a growing demand for organic tea in past decades. Most of this demand is met by imports from developing countries. This article examines the main factors affecting the choice of farm households to adopt organic tea production in Northern Vietnam. We apply a logit model to survey data from 241 Vietnamese tea farming households. We assess the robustness of the results by addressing three important statistical issues: (i) regressor endogeneity, (ii) unobserved heterogeneity at farm level and (iii) missing values. The main results are chiefly robust and largely in line with the theory. We find that farm households with higher revenues, located in rich natural and physical environments, are significantly more inclined to adopt organic tea production. Furthermore, the analysis reveals that farm households who are consulted by extension agents and belong to a tea association increase the odds for the adoption of organic tea cultivation.

Authors:Croonenbroeck C; Odening M, Hüttel S. Pages: 558 - 590 Abstract: We investigate potential asymmetries among bidders in land auctions that may entail market inefficiencies. Using representative data for eastern Germany including winning bids, bidder characteristics and land amenities, we pursue a structural approach to derive distributions of latent land values for different bidder groups. By applying non-parametric techniques, we cannot find evidence for distinct asymmetries while differentiating between legal entities, tenancy status and nationality of bidders. Our findings challenge the hypothesis that land privatisation via auctions discriminates against certain buyer groups – an argument that is often used to justify stricter regulation of agricultural land markets.

Authors:Mishra A; Rezitis A, Tsionas M. Pages: 591 - 618 Abstract: Contract farming (CF) has been offered as a solution to missing markets in developing economies. However, little is known as to how the presence of CF affects production risk, technical efficiency and risk attitudes of the smallholder. This study investigates production risk, technical efficiency, output price uncertainty and risk attitudes of contract and independent farmers. Using a Bayesian estimation method and farm-level data from Nepal, we find that contract farmers are more risk-averse than the independent farmers. Contract farmers can increase output by reducing the scale more than independent farmers. We find that labour and capital are risk-reducing, while land and other inputs are risk increasing for both contract and independent farmers. Finally, independent growers consistently over-predict output prices. PubDate: Tue, 23 Jul 2019 00:00:00 GMT DOI: 10.1093/erae/jbz027 Issue No:Vol. 47, No. 2 (2019)
Authors:Wuepper D. Pages: 619 - 653 Abstract: I investigate whether cultural differences explain why some European regions are more effective in mitigating soil erosion than others. Specifically, I consider environmental preferences and beliefs as well as time preferences. For causal identification, I use a control function approach. The estimates suggest that a 1 standard deviation increase in pro-environmental culture increases erosion mitigation by 2–9 percentage points. This has important implications for research and policy making, which I discuss. PubDate: Wed, 10 Jul 2019 00:00:00 GMT DOI: 10.1093/erae/jbz029 Issue No:Vol. 47, No. 2 (2019)
Authors:Weyori A; Liebenehm S, Waibel H. Pages: 654 - 683 Abstract: This paper investigates whether – and to what extent – a veterinary intervention programme lead to improvements in small-scale cattle farmers’ welfare using a unique panel data set of 443 households from northern Togo. Our results show a positive impact of the interventions on improving farmers’ knowledge and husbandry practices that translates into improved livestock health and productivity. In addition, these positive effects trigger improvements in terms of poverty and vulnerability. The results highlight the important role of targeted interventions that aim to improve livestock health – a key asset among rural households in sub-Saharan Africa.

Authors:Cheptea A; Gaigné C. Pages: 684 - 718 Abstract: We analyse the impact of the Russian food embargo on European and Russian trade patterns using a triple-difference estimation strategy. We quantify the embargo-induced loss in EU28 exports at €125 million per month. Only 45 per cent of the drop in EU exports of banned products to Russia was due to the ban. EU member states were unevenly affected by the ban. The estimated losses of welfare in Russia range from 0.2 to 0.6 per cent (In absolute terms, this represents €18 to €58 of the 2013 revenue of the average Russian consumer.).

Authors:Movchan V; Shepotylo O, Vakhitov V. Pages: 719 - 751 Abstract: Domestic non-tariff measures (NTM) influence firm’s production and import decisions. We introduce NTMs into a model with heterogeneous firms. NTMs increase the cost of production and play a role of a positive demand shifter. Interplay of these two factors leads to ambiguous impact of NTMs on extensive and intensive margins of trade. We test predictions of the model by looking at food-processing firms in Ukraine in 2008–2013. Evidence shows that more SPS regulations on inputs in upstream industries lead to exports of better quality products. At the same time, mandatory certifications have a negative impact on quality by limiting access of domestic firms to new technologies and equipment.

Authors:Granado-Díaz R; Gómez-Limón J, Rodríguez-Entrena M, et al. Pages: 752 - 784 Abstract: This study focuses on the effects of spatial discounting and substitutes sites on the demand for ecosystem services (ES) provided by scattered agroecosystems. New ways of modelling these two effects are proposed, relying on area-based and density-based indices. Data from discrete choice experiments are used, based on a case study of Andalusian olive groves (southern Spain). The results show that model fit is significantly improved by the introduction of these spatial indices, with the best outcome found for the area-based index combined with the inverse of the distance. Results provide evidence of substantial spatial heterogeneity depending on the ES (carbon sequestration, soil conservation and biodiversity), indicating different economic jurisdictions.

Authors:Crosetto P; Lacroix A, Muller L, et al. Pages: 785 - 818 Abstract: An incentivised laboratory framed field experiment with 691 subjects examined the impact of five front-of-pack labels (Multiple Traffic Lights; Reference Intakes; HealthStarRating; NutriScore and Système d’Etiquetage Nutritionnel Simplifié) on food shopping within a catalogue of 290 products. Using difference-in-difference, we estimate the between-label variability of within-subject changes in the shopping’s Food and Standards Agency aggregated nutritional score. All labels improve the nutritional quality (−1.56 FSA points on average). NutriScore is the most effective (−2.65), followed by HealthStarRating (−1.86). Behaviourally, subjects react mostly to the extreme values of the labels and not to intermediate values. Nutritional gains are not correlated with higher expenditure.

Authors:Bonnet C; Trachtman C, Van Dop M, et al. Pages: 819 - 847 Abstract: We review the current literature on applied policy analysis and empirical structural food industrial organisation research. Within that context, we provide an overview on the state of research and summarise the core problems researchers face when estimating the demand and structural supply models implemented in applied research to date. We focus on important themes, such as providing a better understanding of vertical relationships in food markets, price formation, competition issues, environmental and nutritional policies.
