Authors:Vandercasteelen J; Dereje M, Minten B, et al. Pages: 471 - 503 Abstract: Improved technologies are increasingly promoted to farmers in sub-Saharan Africa to address low agricultural productivity. There is, however, a lack of evidence on how adoption affects farmers’ labour use, gender roles and profitability. This paper analyses the farm level impacts of the recently introduced row planting technology in teff production in Ethiopia. Using a randomised controlled trial, we show that row planting significantly increases the total labour requirement and allocation but not teff yields, resulting in a substantial drop in labour productivity. There is no significant profitability effect at the farm level, seemingly explaining the limited success in upscaling the programme.

Authors:Durevall D. Pages: 505 - 529 Abstract: Cost pass-through to retail prices shows how changes in marginal costs are allocated between producers and consumers, and it is, therefore, closely related to market structure and competition. This paper uses Swedish data on coffee products at the barcode level to evaluate pass-through from the cost of green coffee beans, the main marginal cost, to the retail price of roasted and ground coffee. First long-run cost pass-through is estimated for each product, and then regression is used to analyse how pass-through varies across market shares, retailer-owned brands and other product characteristics. A general result is that pass-through is roughly complete for products with large market shares, while those with small market shares have low pass-through rates. There is no evidence that retailer-owned brands have higher pass-through than brand-name products with similar market shares, which would be the case if retailer-owned brands avoided double marginalisation through vertical integration. Thus, although there is not perfect competition in the Swedish coffee market, a large part of it appears to be highly competitive.

Authors:Brækkan E; Thyholdt S, Asche F, et al. Pages: 531 - 552 Abstract: Smooth operators such as time trends are often applied to deal with unidentified demand shifters. However, if unknown factors affect demand irregularly, a time trend fails to capture the variation. We present an index approach for estimating irregular demand shifts, decomposing total demand shifts into predicted and unexplained effects. This allows separating demand shifts caused by known factors like income and substitution effects from unknown impacts on demand. Our application on farmed salmon shows unknown factors impact demand irregularly both between regions and within regions over time. Unknowns contribute to more than half of global salmon demand growth in recent years. PubDate: Thu, 15 Mar 2018 00:00:00 GMT DOI: 10.1093/erae/jby003 Issue No:Vol. 45, No. 4 (2018)
Authors:Vaissière A; Tardieu L, Quétier F, et al. Pages: 553 - 582 Abstract: Biodiversity offsetting (BO) is aimed at achieving no net loss of biodiversity in the context of economic development. Through a choice experiment in Northern France, we show that farmers have a clear preference for not signing up BO contracts. The contracts they accept may only be suitable for offsetting temporary impacts on already degraded areas of natural habitat but not for permanent impacts on high-quality habitat. We find that the introduction of a conditional monetary bonus can improve the organisational and ecological efficiency of BO because it increases the enrolled acreage in a BO contract per farmer albeit at an increased cost for developers.

Authors:Crespo Cuaresma J; Hlouskova J, Obersteiner M. Pages: 583 - 615 Abstract: We analyse the role played by market fundamentals, speculation and macroeconomic conditions as empirical determinants of price changes in Arabica coffee. We combine model averaging techniques to explain historical patterns with an in-depth analysis of out-of-sample predictability of Arabica coffee prices using fundamentals as well as macroeconomic and financial variables. Our results indicate that variables related to global macroeconomic and financial developments contain valuable information to explain the historical pattern of coffee price developments, as well as to improve out-of-sample predictions.

Authors:Bareille F; Letort E. Pages: 617 - 639 Abstract: Previous studies on the productive value of biodiversity have emphasised that crop diversity increases crop yields. Here, we focus on the management of crop biodiversity for wheat, winter barley and rapeseed productions. We introduce productive capacity of biodiversity into a structural dynamic model with supply, variable input demand and acreage functions. We estimate the model for a sample of French farms between 2007 and 2012. We highlight that biodiversity indicators influence the yield of crops and variable input uses. We find evidence that farmers manage their acreage to benefit from the productive capacity of crop biodiversity.

Authors:Finger R; Dalhaus T, Allendorf J, et al. Pages: 641 - 674 Abstract: We investigate determinants of dairy producers’ risk exposure using a unique combination of foci on (i) downside risks, (ii) a holistic representation of revenues from milk and animal sales, (iii) climatic extremes and (iv) the role of animal health. A sample of German dairy farms reveals that animal health and heat stress indicators influence mean and semi-variance of revenues. For instance, heat stress exposure reduces expected milk revenues significantly. In the case of animal health-related indicators, our results show trade-offs between expected revenues and downside risks. Furthermore, variabilities in revenues from milk and animal sales are significantly interrelated. PubDate: Thu, 10 May 2018 00:00:00 GMT DOI: 10.1093/erae/jby012 Issue No:Vol. 45, No. 4 (2018)
