Are Academics Messy? Testing the Broken Windows Theory with a Field Experiment in the Work Environment AgEcon
Ramos, Joao; Torgler, Benno.
We study the broken windows theory with a field experiment in a shared area of a workplace in academia (department common room). We explore academics’ and postgraduate students’ behaviour under an order condition (clean environment) and a disorder condition (messy environment). We find strong support that signs of disorderly behaviour triggers littering. In the disorder treatment 59% of the subjects litter compared to 18% in the order condition. The results remain robust when controlling compared to previous studies for a large set of factors in a multivariate analysis. When academic staff members and postgraduate students observe that others violated the social norm of keeping the common room clean the probability of littering increases ceteris paribus by...

The Effect of Risk, Ambiguity and Coordination on Farmers’ Adaptation to Climate Change: A Framed Field Experiment AgEcon
Alpizar, Francisco; Carlsson, Fredrik; Naranjo, Maria.
The risk of losses of income and productive means due to adverse weather associated to climate change can significantly differ between farmers sharing a productive landscape. It is important to learn more about how farmers react to different levels of risk, under measurable and unmeasurable uncertainty. Moreover, the costs associated to investments in reduced vulnerability to climatic events are likely to exhibit economies of scope. We explore these issues using a framed field experiment that captures realistically the main characteristics of production, and the likely weather related losses of premium coffee farmers in Tarrazu, Costa Rica. Given that the region recently was severely hit by an extreme, albeit very infrequent, climatic event, we expected to...

Finding Missing Markets (and a disturbing epilogue): Evidence from an Export Crop Adoption and Marketing Intervention in Kenya AgEcon
Ashraf, Nava; Gine, Xavier; Karlan, Dean S..
In much of the developing world, many farmers grow crops for local or personal consumption despite export options which appear to be more profitable. Thus many conjecture that one or several markets are missing. We report here on a randomized controlled trial conducted by DrumNet in Kenya that attempts to help farmers adopt and market export crops. DrumNet provides smallholder farmers with information about how to switch to export crops, makes in-kind loans for the purchase of the agricultural inputs, and provides marketing services by facilitating the transaction with exporters. The experimental evaluation design randomly assigns pre-existing farmer self-help groups to one of three groups: (1) a treatment group that receives all DrumNet services, (2) a...

Eliciting Risk Preferences: A Field Experiment on a Sample of French Farmers AgEcon
Bougherara, Douadia; Gassmann, Xavier; Piet, Laurent.
We designed a field experiment involving real payments to elicit farmers’ risk preferences. Farmers are a very interesting sample to study since risk has always played an important role in agricultural producers’ decisions. Besides, European farmers may face more risky situations in the future. In this context, it is very important for any economic analysis focusing on agriculture to correctly assess farmers’ behaviour in the face of different sources of risk. We test for two descriptions of farmers’ behaviour: expected utility and cumulative prospect theory. We use two elicitation methods based on the procedures of Holt and Laury (2002) and Tanaka et al. (2010) on a sample of 30 French farmers. The experiment consists in asking subjects to make series of...
