Beef production is a major contributor to greenhouse gas (GHG) emissions. We conducted a choice experiment to analyse consumers’ willingness to pay (WTP) for beef characterised as carbon-friendly. We included a treatment where respondents were informed about carbon-friendly production and surveyed beliefs regarding beef production’s contribution to GHG emissions. The results show that consumers have a positive WTP for carbon-friendly beef and providing information increases the premium that they are willing to pay for it. The findings also suggest that consumers who believe that beef production contributes to GHG emissions are willing to pay more for beef carrying a carbon-friendly label.

We present a new approach to establish an empirical overview of farmers’ risk preferences and the characteristics associated with these preferences. We rely on an Individual Participant Data Meta-analysis whereby we identify studies eliciting risk preferences through self-assessments and Holt and Laury lotteries, and construct and analyse a unique dataset of 5,157 farmers from 19 studies in 13 European countries. Our results reveal significant heterogeneity in risk preferences across elicitation methods, within and across studies, risk domains and farm and farmer characteristics. European farmers are on average risk-averse when risk preferences are elicited by lotteries, and on average risk-neutral when elicited by self-assessments. Beyond differences in the average risk aversion, there are distributional differences pointing to a limited convergence between elicitation methods and a larger explanatory power of farm and farmer characteristics to determine risk preferences elicited with self-assessments compared to lotteries.

This introduction presents five articles of the virtual issue on bioeconomy innovation pipelines and supply chain shocks. The presented cases use alternative methodological approaches with their own advantages and disadvantages. The conclusion we can draw is that the specificities of individual case studies make it difficult to generalise and many more cases would be needed to perform a meta-analysis. We encourage agricultural economists to provide further research on detailed cases, which will be particularly important for gaining a better understanding of the potential effects of the EU Green Deal.

Using Rwandan Integrated Household Living Conditions surveys (2013/2014 and 2016/17), we investigate whether financial inclusion leads to improved nutrition in rural Rwanda. Our empirical evidence shows a robust positive impact of financial inclusion by formal financial institutions, although informal institutions like tontines were ineffective in improving food expenditure or nutrition. Furthermore, the heterogeneous marginal effects of financial inclusion reduce the gender gap between the food expenditure and nutrition of female- and male-headed households. The results, hence, suggest that the country should promote formal financial inclusion to provide wide-ranging welfare effects by improving food security, nutrition and food expenditure in its rural communities.

Understanding agricultural commodity futures is crucial for efficient business operations. This study employs textual machine learning on 290,271 articles (2009–2020) focusing on corn markets, aiming to model the impact of news on corn futures pricing. Our novel approach enables the identification of seven distinct topics within corn news, offering a comprehensive view of the news coverage spectrum. Soybean biofuel news notably influences corn prices, while exports, weather and wheat news significantly impact pricing uncertainty. These insights deepen our understanding of factors shaping corn futures and highlight machine learning’s potential in agricultural economic analysis, enabling more accurate market predictions and policy decisions.

While there is strong evidence that becoming an exporter increases a firm’s productivity, underlying mechanisms that explain such a relationship remain largely unexplored. This paper analyses the contribution of the complementarity between exporting and investment in technology as a potential driver of export-related productivity gains. We employ firm-level data on production and trade combined with information on new products in the French dairy industry to conduct a causal mediation analysis between exporting, innovation investment, innovation output and productivity. Our estimation result show that starting exports increase the productivity by eight percentage points. Our mediation analysis reveals that innovation (investment and output) explains 31 per cent of this productivity growth.

We analyse the effect of front-of-package nutrition labelling using the example of France, where Nutri-Score was adopted in 2017. Our focus is on changes in available products, i.e. on producer choices rather than consumer choices. Employing a difference-in-differences approach, we find that products introduced or altered after the change receive better Nutri-Score ratings than those introduced before the adoption, indicating a shift to items that are healthier overall. In addition, there is some evidence of bunching at the cutoffs for better Nutri-Score grades, which suggests that the improvements are at least in part a strategic reaction to the Nutri-Score introduction.

Our paper assesses the technical and economic effects of adopting environmental standards aimed at favouring biodiversity on wheat production. We consider two standards with different levels of environmental stringency. We use data on French wheat production at the plot level from the period 2014–2020. We implement an endogenous switching regression model taking into account two sources of endogeneity, environmental standards adoption and inputs quantity use. Our results indicate that adopting the more stringent standard slightly decreases wheat yield and quality. In contrast, it induces a low increase in wheat price. The price premium of the more stringent environmental standard merely compensates for the negative effect of the standard’s adoption on quality.

We investigate the impact of severe drought shocks in Morocco’s agricultural sector. Using a staggered difference-in-differences design, we estimate that climatic shocks resulted in a job displacement of approximately 6.5 percentage points for workers exposed to severe drought events. Additionally, we observe that, overall, approximately 39 per cent of these workers remained unemployed, leading to a partial reallocation failure. These effects are significant only for severe and extreme shocks, persist for at least 5 years, and are more pronounced among informal and female workers.

Organic inputs can be effective in reversing soil degradation and improving crop yields, but are often underused in a developing country context. This study seeks to determine whether farmer field days (FFDs) are effective in disseminating information about novel organic inputs, and the extent to which they increase demand for these products. Using experimental auctions to measure willingness to pay (WTP) among smallholder farmers in Western Kenya, we find that those farmers exposed to information from FFDs related to biochar and vermicompost, novel organic inputs, have lower WTP for the products. We present evidence that this is likely driven by two factors in particular: changes in perceptions of input profitability and heterogeneity in yields across demonstration plots within field day sites.
