The Influence of the Strength of Financial Institutions and the Investment-Production Delay on Commodity Price Cycles: A Framed Field Experiment with Coffee Farmers in Colombia.

Submitted by Manuela Fonseca on

Commodity price cycles can arise when there is a tendency to invest more (less) when current prices are high (low). Traditionally this behavior is interpreted as based upon naïve expectations. However, weak financial institutions can also cause this behavior. When borrowing is hard and saving is risky farmers cannot invest

Chipping in for a cleaner technology: Experimental evidence from a framed threshold public good game with students and artisanal miners.

Submitted by Manuela Fonseca on

We analyze whether the decisions made by university students in a framed threshold public good game meet what artisanal gold miners decided in a lab-in-the-field experiment. This work contrasts with current literature in which the comparison between lab and lab-in-the-field has considered context-free situations. In general, we find more behavioral convergences than divergences between students and miners. Similar to a set previous literature, these results show lab experiments on social dilemmas can be externally valid.

Smallholder rice farmers’ post-harvest decisions: preferences and structural factors

Submitted by Salvatory Macha on

We study post-harvest decisions among Tanzanian rice farmers. Risk and time preference experiments are used to understand post-harvest decisions. In particular, we investigate storage and processing decisions, which according to our study can increase income by more than 50 per cent, but also introduce risk and time delays. Experimentally elicited risk and time preferences are statistically significant in explaining these post-harvest decisions. Impatient farmers are less likely to store paddy, and risk-averse farmers are less likely both to process and store paddy for future sales.

The Link Between Response Time and Choices in Choice Experiments

Submitted by Eugenia Leon on
EfD Authors:

Response time is a possible indicator of the cognitive processes employed by choice experiment participants when making choices. The decision-making literature suggests a positive correlation between slower response time and rational thinking, which is consistent with standard theories of decision-making. The aim of this paper is to investigate the relationship between response time and respondents’ choices. We disentangle preference and willingness-to-pay estimates and explore whether response time sheds light on these aspects.

Charging for Plastic Bags as an Effective Nudging Policy

Submitted by Eugenia Leon on
EfD Authors:

Policymakers have little experience regarding designing the right levels of pricing for plastic bags. Prices for bags are generally set low and are largely a symbolic reminder to consumers of the environmental concerns attributed to plastic bag use. The ineffectiveness of charging for bags in the long term, in countries such as South Africa, makes it imperative that we map the demand curve. Getting the price “right” depends on the size of the externality. Charging for plastic bags is therefore an effective nudging policy.

Household appliance ownership and income inequality: Evidence from micro data in China

Submitted by Hang Yin on

As the residential sector is becoming increasingly important in the total energy consumption and appliance ownership is a significant but under-examined driver, this study investigates the relationship between income inequality and appliance ownership using panel data from the China Health and Nutrition Survey (CHNS). We find that income inequality has negative impacts on appliance penetration rate across specifications, except for the initial development stage.

Sanctioned Quotas vs. Information Provisioning for Community Wildlife Conservation in Zimbabwe: A Framed Field Experiment Approach

Submitted by Anonymous (not verified) on

We investigate the behavioural responses of resource users to two policy interventions: sanctioned quotas and information provisioning. We do so in a context in which multiple resources (pastures and wild animal stocks) are connected and could substantially and drastically deteriorate as a result of management. We perform an experimental study among communities that are managing common pool wildlife in Zimbabwe.

Between-group competition enhances cooperation in public goods appropriation games

Submitted by Manuela Fonseca on

Cooperation in public goods games increases in the presence of between-group competition. In this study, we validate the effect of between-group competition in a different social dilemma, a resource appropriation game. Unlike the voluntary contributions setting, group performance in this game increases with the exercise of a passive choice: not appropriating units in an open-access resource. We conducted an incentivized experiment using 276 undergraduate students in which groups of four subjects played a resource appropriation game.
