Authors:Yitayew A; Abdulai A, Yigezu Y. Pages: 527 - 556 Abstract: AbstractIn this study, we test the hypothesis that small-scale testing can reduce the risk and uncertainty of trying new technologies. We conducted a field experiment, in a cluster randomised control trial setting, to examine whether the availability of divisible packages of seeds influences smallholder farmers’ decisions to try a new wheat variety. Our results show that the adoption of the newly introduced wheat variety was higher in the villages where small seed packages were introduced. We find that smallholder farmers tend to experiment on the newly introduced variety on their farmland and are less likely to adopt the new variety as a coping mechanism for risk exposure at the stage of experimentation. The results from treatment heterogeneity reveal that supplying seed in small bags had differential causal effects on individual farmers. The intervention which made small seed bags available impacted relatively younger and poorer farmers the most. This finding provides an insight into the significance of seed delivery in small bags to improve the use of seeds of new varieties by smallholders.

Authors:Ilin C; Shi G. Pages: 557 - 592 Abstract: abstractIn this paper we examine the effect of competition on price dispersion and argue that the effect is contingent on the ability of firms to meet market demand. Our comparative static results show that competition among symmetrically capacity-unconstrained firms, or among firms with asymmetric capacities leads to an overall price increase along the distribution function. To investigate these findings empirically, we use a novel data set from the U.S. corn seed industry with firm and farm level sales information for conventional and genetically modified corn seeds between 2004 and 2009. We estimate the empirical model using the Fixed Effect Instrumental Variable Quantile Regression and find evidence consistent with the theory. The analysis also shows that capacity-unconstrained seed firms charge a price premium, confirming the positive relationship between product availability and pricing found in our theoretical model.

Authors:Fliessbach A; Ihle R. Pages: 593 - 614 Abstract: AbstractSimultaneous spikes in global prices of many agricultural commodities in recent years have induced an interest in quantifying the degree of synchronisation of these movements. We suggest a conceptual framework explaining why temporally varying price synchronisation may happen and propose the concordance index for the empirical measurement of the incidence, symmetry and permanence of synchronisation. We establish that the index generates insights into time series dynamics which are complementary to those obtained from cointegration analysis. We illustrate the approach with an application for the co-movement in cyclical components of pig and cattle prices in three Latin American countries. The findings reveal moderate synchronisation levels which show asymmetric instabilities. PubDate: Mon, 15 Mar 2021 00:00:00 GMT DOI: 10.1093/erae/jbab015 Issue No:Vol. 49, No. 3 (2021)

Authors:Oviedo J; Campos P, Caparrós A. Pages: 615 - 643 Abstract: AbstractWe applied discrete choice contingent valuation to the amenities consumed by non-industrial private forest owners in Andalusia (Spain) in a survey of 765 landowners. The landowners’ median willingness to accept compensation from an alternative investment for giving up land amenity consumption is EUR 387.8 per hectare yearly. The preferred model shows diminishing marginal values of amenity consumption with property size, negative effects of eucalyptus and Aleppo pine presence and positive effects of distance to urban centres. We discuss the performance of the question formats and models employed and recommend the single-bounded format in this valuation context.

Authors:Jiménez D; Saldarriaga-Isaza A, Cicowiez M. Pages: 644 - 667 Abstract: AbstractWe assessed the economic effects of the agricultural policy that is proposed as part of the 2016 peace accord in Colombia. We used a newly built social accounting matrix for Colombia to calibrate a computable general equilibrium model. We found that the value added, demand for labour and factor incomes increased in the areas most affected by the conflict, while the opposite occurred in the other areas. In general, distributional effects between urban and rural areas are strongly conditional on the financing mechanism adopted by the government.

Authors:Tabe-Ojong M; Mausch K, Woldeyohanes T, et al. Pages: 668 - 695 Abstract: AbstractEnhancing agricultural productivity through the adoption of improved technologies presents a credible pathway to economic development and poverty reduction especially through increased commercialisation of production. We used a triple hurdle (TH) model to estimate the production and commercialisation of smallholder farmers in Ethiopia. In doing so, we account for the adoption of improved Cicer arietinum (chickpea) varieties on commercialisation using a three-wave panel data set. We estimate a correlated random effect model with a control function and find the adoption of improved chickpea to have a significant positive effect on smallholder commercialisation. Our findings that are robust over different specifications and identification strategies also support the role of transaction cost in driving market participation (MP). Finally, we argue that the TH model is a better fit to the commonly used double hurdle model for MP, when not all households in a population produce a particular crop.

Authors:Schaak H; Musshoff O. Pages: 696 - 718 Abstract: AbstractThis paper studies the profitability of investments in agricultural land, using the rent–price ratio (RPR) as a profitability measure. In order to allow for district-level heterogeneity, the full conditional distribution of the RPR is modelled using a generalised additive model for location, shape and scale. The analysis is based on data from Lower Saxony, Germany. The profitability of investments in land varies between and within districts. The variation can be explained by differences in the farming structure, the production programme and economic indicators. Further, differences in the distribution of the RPR between arable land and grassland are found. PubDate: Fri, 10 Dec 2021 00:00:00 GMT DOI: 10.1093/erae/jbab052 Issue No:Vol. 49, No. 3 (2021)
