We present a novel procedure based on eco-efficiency for assessing farm-level effects of technology adoption while considering secondary effects. Secondary effects are defined as structural and behavioural adaptations to technology that may impact environmental, social or economic outcomes. We apply the procedure to automatic milking systems (AMS) in Norway and find that AMS induces secondary effects, most strongly by decreasing labour per cow and increasing herd sizes. For estimating effects of AMS we employ a novel causal machine learning approach. AMS induce heterogenous effects on eco-efficiency, negatively associated with herd expansion and labour per cow.

This paper examines the relationship between smallholder commercialisation and rural household welfare. Employing a comprehensive three-wave panel dataset of smallholder maize farmers in Ethiopia, we find a positive association between commercialisation and household income which translates to wealth endowments through asset ownership and accumulation. We also show that commercialisation is associated with poverty reduction by reducing the prevalence of income poverty and the poverty gap. Deep diving into who benefits most from commercialisation, we find that agricultural commercialisation is inclusive and benefits all households. However, the greatest welfare gains accrue to income-poor households, suggesting some potential for reducing rural inequality. These insights support existing evidence that smallholder commercialisation is pro-poor and could be a significant entry point for stirring income growth and development in rural areas. Consequently, supporting poor and marginalised farmers with resources needed to boost agricultural production and commercialisation are relevant steps in the right direction of ensuring integrated rural development.

This study utilises structural gravity models to examine the impact of globalisation on distance in agricultural and processed food trade, the relative effects of international distance and home bias effects. The results show that larger internal distances lower domestic sales. The home bias effect is substantially larger in agricultural commodities compared to processed agricultural commodities. Omitted variable bias is observed in friction variables when the relative intra-national distance and home market bias are excluded. After controlling for relative intra-national trade costs and the home bias effect, globalisation does not lead to a smaller impact of distance on trade. Substantial heterogeneity exists when analysing individual commodities.

Our objective is to identify the individual flexibility of dairy farms, which may be the result of heterogeneous input adjustment costs, based on their observed short-run responses to price variations. For this purpose, we propose an analytical framework based on the panel smooth transition regression model with farm-specific threshold parameters. Our model is estimated using data from a sample of French dairy farms over the period 2007–2018. Our empirical results reveal heterogeneous levels of flexibility for these farms, with the most flexible farms appearing to be more autonomous both financially and in terms of animal feed.

Abstract Cellulosic biofuels from non-food feedstocks, while appealing, continue to encounter uncertainty about their induced land use change (ILUC) effects, net greenhouse gas (GHG) saving potential and their economic costs. We analyse the implications of multiple uncertainties along the biofuel supply chain from feedstock yields, land availability for production to conversion to fuel in the refinery on these outcomes. We find that compared to corn ethanol, cellulosic biofuels have a substantially smaller and less uncertain ILUC-related GHG intensity and lead to larger GHG savings at lower welfare costs of abatement, indicating the potential to make robust and substantial contributions to cost-effective climate change mitigation.

Abstract Using a hybrid multi-regional input–output approach, we traced sustainability footprints of a nutrient recovery strategy from sewage sludge applied in Italy. We then compared the results with the most common landfilling practice. Overall, accounting for indirect global upstream effects, using sewage sludge for organic fertiliser production generates more jobs and reduces more greenhouse gas emissions than landfilling. By contrast, landfilling stimulates the whole economy more, generating higher indirect turnover and reduces energy carrier use more. Finally, we accounted for uncertainties in these results using an error propagation method based on Monte Carlo simulations.

This study compares a real choice experiment (RCE) with three commonly used experimental auction (EA) mechanisms (Becker–DeGroot–Marschak, random nth price auction (RNPA), second price auction (SPA)) to determine whether willingness to pay (WTP) estimates differ across these elicitation methods. We use quality labels on eggs as the empirical application and find that the SPA, RNPA and RCE yield similar WTP estimates, while the BDM mechanism generally produces higher WTP estimates. We also compare these EAs and the RCE in an induced value setting and find that the BDM auction produces greater deviations from the underlying value than the other EAs and RCE. We suggest that RCEs may be preferable to BDMs for collecting WTP estimates in logistically difficult experimental settings.

This paper analyses data from a novel collective agri-environmental scheme (cAES) in Alsace, France, designed to protect the local European hamster population by motivating farmers to engage in habitat conservation measures. In contrast to typical conservation contracts that pay individual farmers based on their own performance, the cAES studied here pays farmers only when the percentage of land conserved by all farmers within a collective zone reaches a critical threshold. We find that the likelihood of participation is higher for farmers with a relatively large agricultural surface within the collective zone, increases with the number of farmers in a collective zone, and increases over time. Those with more land in the collective zone allocate more acreage to conservation. We define different contributor types and provide insight into the possible motives underlying contributions to collective conservation schemes.
