Payment vs. compensation for ecosystem services: do words have a voice in the design of environmental conservation programs?

We examine whether and how word choice can affect individual perceptions about a proposed Payments for Ecosystem Services (PES) program when objective outcomes are similar. From a traditional economic perspective, this type of manipulation would be considered unlikely to affect perceptions and behaviour, especially in the presence of pecuniary incentives and repeated decisions among sophisticated agents. From a behaviourally informed perspective, however, psychological and political theories of wording argue that word choice can have a significant impact on economic behaviour. To substantiate this discussion, we conduct a survey experiment that tests the impact of the words ‘payment’ and ‘compensation’ on favorability ratings of a proposed PES program. These preliminary findings suggest that the words used to describe public policies can be influential non-pecuniary interventions

Moral self-licencing and social dilemmas: an experimental analysis from a taking game in Madagascar

This article explores whether previous good deeds may license antisocial behaviour, such as appropriating a social surplus for private benefits, in a developing country context, namely Madagascar. We design a two-step framed experiment, with one control treatment (a neutral task) and three test treatments (tasks enabling subjects to earn moral credits in three different ways), followed by a taking game in which subjects are given the opportunity to take an amount from a fund allocated to their University. On average, we find that participants in the three licencing conditions appropriate more than those in the control group and that further differences emerge according to the way the moral credits have been earned

Are impatient farmers more risk-averse? Evidence from a lab-in-the-field experiment in rural Uganda

Based on data from a field-experiment in rural Uganda, we show that impatient farmers are more risk-averse than patient farmers. We relied on a simplified version of the Convex Time Budget (CTB) method to elicit farmers’ time preferences and on an independent method for eliciting their risk-preferences. We report two important findings. First, we show that our simplified CTB method applied to farmers from Uganda replicates the key findings of Andreoni and Sprenger’s lab experiments that involved student subjects. Second, we establish the existence of a negative correlation between risk tolerance and impatience, based on two independent measures

The behavioural foundations of female entrepreneurship: what can experiments teach us?

We bridge the women entrepreneurship literature with the experimental economics literature on gender, with the aim to contribute a different perspective on the barriers and opportunities for women entrepreneurs, and one that we hope can help both fields by questioning some of the implicit assumptions that are often made (and used in policy) about the reasons for the differences observed between male and female headed businesses. In the course of the discussion we also revisit the definition of entrepreneur and the role of risk aversion in both neoclassical theory and in the identity perspective and draw implications in the context of the digital age and its potential to level the playing field between women and men in business venture

Once good, always good? Testing nudge’s spillovers on pro environmental behavior

It is a common assumption to believe that encouraging pro environmental behavior (PEB) in one domain would lead to increased PEB in other domains (best-case scenario) or just be restricted to the initial targeted domain (worst-case scenario). Evidence from a rapidly growing literature on moral licensing suggests that interventions targeting behavioral change could lead to an even worse scenario, with individuals starting to underperform in one domain, as a compensation for their good performance in other domains. We propose to study the dynamic of PEBs when individuals are exposed to a specific nudge (priming) via an original experiment designed to capture actual behavior. We found that priming could increase PEB, but does not thwart moral licensing. Primed individuals end up doing worse than non-primed individual under a moral licensing condition. A more comprehensive view of the mechanisms underlying behavioral change is essential to support sustainable policies

Keep Calm and Carry On: Gender differences in Endurance

We investigate endurance, the capacity to maintain levels of performance through internal rather than external motivation in non-rewarding tasks and over sequences of tasks, though a lab experiment. The significant driver of performance is payment scheme order for women and payment schemes for men. Both women and men respond to social cues, through increased intrinsic motivation (ambition) for women and through extrinsic motivation (competition) for men. We suggest implications for reward schemes in the workplace and for selection into executive positions

A mixed-methods approach to understanding barriers and facilitators to healthy eating and exercise from five European countries: highlighting the roles of enjoyment, emotion and social engagement

Healthy adults are consistently falling below national and international recommendations for physical activity and dietary intake across Europe. This study took a co-creative approach with adult samples from five European countries to qualitatively and quantitatively establish motivators, barriers and sustaining factors for positive health behaviour change. Stage 1 delivered a newly-designed online programme, creating a community who identified challenges, motivators and solutions to sustaining positive healthy eating and physical activity behaviours. Stage 2 administered an online survey (developed from Stage 1 findings) to a larger sample to quantify the relative importance of these motivators and barriers. Results from both stages indicated enjoyment, positive emotions, and reward as key motivators for both behaviours across all five countries. Barriers included habit-breaking difficulties, temptation and negative affective states. Those with a high BMI placed more importance on social pressure than those with healthy BMI. Participants’ reports of motivators and barriers reflected relevant approaches from consumer science, behavioural economics, and psychology. Interventions supporting adults who are not chronically ill but would benefit from improved diet and/or physical activity should not focus exclusively on health as a motivating factor. Emphasis on enjoyable behaviours, social engagement and reward will likely improve engagement and sustained behaviour change

Neurobiol Aging

GRN mutations are frequent causes of familial frontotemporal degeneration. Although there is no clear consensual threshold, plasma progranulin levels represent an efficient biomarker for predicting GRN mutations when decreased. We evaluated plasma levels to determine whether it could also predict age at onset, clinical phenotype, or disease progression in 160 GRN carriers. Importantly, progranulin levels were influenced by gender, with lower levels in male than in female patients in our study. Although we found no correlation with age at onset or with clinical phenotype, we confirmed that decreased level predicts GRN mutations, even in presymptomatic carriers more than four decades before disease onset. We also provided first evidence for the stability of levels throughout longitudinal trajectory in carriers, over a 4-year time span. Finally, we confirmed that progranulin levels constitute a reliable, cost-effective marker, suitable as a screening tool in patients with familial frontotemporal degeneration, and more broadly in patients without family history or with atypical presentations who are less likely to be referred for molecular diagnosis
