Food security, along with growing population and the associated environmental concerns, make food waste and loss a central topic in economic analysis. While food losses occur mostly at the production, postharvest and processing phases of the supply chain, food waste takes place mainly at the end of the chain and therefore concerns primarily the habits and behaviour patterns of retailers and consumers. Many solutions and practices have been proposed and oftentimes implemented in order to "keep food out of landfills", thus reducing food waste at the source. However, little attention has been paid to the possible sharing of consumer-side food surplus. In this context, food sharing could represent an effective way to tackle food waste at the consumers' level, with both environmental and economic potential positive effects. Currently, several initiatives and start-ups are being developed in the US and Europe, involving the collection and use of the excess of food from consumers and retailers and the promotion of collaborative consumption models (e.g. Foodsharing, Growington, Feastly, etc.). Nevertheless, there is still little empirical evidence testing the effectiveness of introducing sharing economy approaches to reduce food waste. This study seeks to fill this gap through a framed field experiment. We run two experimental treatments; in the control treatment students were asked to behave according to their regular food consumption habits, and in the food sharing treatment the same students were instructed to purchase food, cook and consume it collectively. Preliminary results showed that the adoption by households of food sharing practices do not automatically translate into food waste reduction. A number of factors (environmental and economic awareness, domestic skills and collaborative behaviors) might act as 'enablers' to make sharing practices effective.

This work aims to identify and quantify the biases behind the anomalous behavior of people when they deal with the Three Doors dilemma, which is a really simple but counterintuitive game. Carrying out an artefactual field experiment and proposing eight different treatments to isolate the anomalies, we provide new interesting experimental evidence on the reasons why subjects fail to take the optimal decision. According to the experimental results, we can quantify the size and the impact of three main biases that explain the anomalous behavior of participants: Bayesian updating, illusion of control, and status quo bias.

This paper aims to unmask the inadequacy of the review process of a sample of fee-charging journals in economics. We submitted a bait-manuscript to 104 academic economic journals to test whether there is a difference in the peer-review process between Article Processing Charges (APC) journals and Traditional journals which do not require a publication fee. The submitted bait-article was based on completely made-up data, with evident errors in terms of methodology, literature, reporting of results, and quality of language. Nevertheless, about half of the APC journals fell in the trap. Their editors accepted the article in the journals and required to pay the publication fee. We conclude that the Traditional model has a more effective incentive-mechanism in selecting articles, based on quality standards. Otherwise, we confirm that the so-called "Predatory Journals" - i.e. academic journals which accept papers without a quality check - exploit the APC scheme to increase their profits. They are also able to enter whitelists (e.g. Scopus, COPE). Accordingly, poor-quality articles published on APC journals shed the lights on the weakness of methodologies based on a mechanical inclusion of academic journals in scientific database indexes, succeeding in being considered for bibliometric evaluations of research institutions or scholars' productivity.

This study presents an analysis of hypothetical bias in WTA valuation connected with a bargaining game setting, in a field experiment context. The field of the experiment is the History Channel television "Pawn Stars". We collected a unique dataset that allowed us to analyze not only the gap between real and hypothetical WTA but also how they affect the bargaining game and vice versa. The general aim of this paper is to study the hypothetical bias related to subjects' WTA, and the factors that mostly affect it. The main results, of our paper, show that the hypothetical bias is positive, and it depends mainly on the price range and the type of good.
