Food discrete choice experiments typically define product alternatives with a researcher-predetermined and sometimes arbitrary quantity. Results reveal that the use of a researcher-prespecified experimental quantity leads to biased welfare estimates. Differences in marginal utility of money are found with a resulting upward bias in willingness to pay estimates when small pre-defined product quantities are used. Higher-income consumers show more evident bias. This evidence cautions the use of a researcher-predetermined quantity to design alternatives in choice tasks and also proposes an alternative experimental design that accounts for these effects by matching the quantity in experiments to consumer’s actual purchase quantity.

Since the inception of the novel coronavirus, immense research efforts have been made to understand how several economic indicators, including food security, would be affected. With India racing behind the United States in terms of daily infection rate and being a country with challenging food security issues, it is important to investigate how the presence of the pandemic has influenced the dynamics of food prices in the country. This paper considers seven price series from 167 markets across the five regions in India as well as the growth rate of COVID-19 infection. The paper uses a time-varying autoregressive model to investigate the nonlinear dynamics of food prices in relation to the pandemic in India. The resultant models reveal strong asymmetric properties with shock-inflicted persistence, which appear not to converge over the simulation period. Moreover, in terms of the location of the burden of the pandemic impact, we find a food product divide.

We investigate consumers’ preferences towards local and organic food via a framed field experiment involving revealed multiple discrete–continuous choices. Participants were endowed with a cash amount as a budget to purchase any desired quantity of different products. We modelled choices via the multiple discrete–continuous nested extreme value model. Central to our investigation is the test of the hypothesis of the constant effect of attitudes across consumption doses, which is normally an assumption invoked a priori and without testing in discrete choice analyses. Our results support the hypothesis and reveal a strong preference towards organic and local products, associated with both the highest baseline utility and the lowest satiation effect.

Stefano Ciliberti, Simone Severini, Maria Giovanna Ranalli, Luigi Biagini, Angelo Frascarelli
This paper assesses how efficiently Common Agricultural Policy direct payments enhance farm incomes by applying a quantile continuous treatment effect model on the Italian Farm Accountancy Data Network sample. Adding to previous analyses, we show that income responses to direct payments are higher in large farms rather than in small farms and lower in farms benefiting from larger levels of support. This suggests that direct payments are not very efficient in supporting incomes of small farms and reducing the disparity existing within the farm population. Furthermore, results suggest that there is scope to reduce the amount of payments provided to highly supported farms.

This paper investigates the influence of the risk perception of farmer−herder (FH) conflicts on rural households’ production decisions. Extending the farm household model to include the risk perception of farmer−herder conflicts, we test hypotheses derived using primary data from 401 rural households in Nigeria. Results indicate that higher risk perception of FH conflict reduces fertiliser use and increases the time allocated for farm work. Dividing households based on their risk aversion, we find that risk-averse households rent-in significantly less cropland compared to risk-taking households. Findings highlight the need for policies that sustainably tackle FH conflicts for improved agricultural production.
