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.

This paper assesses the effect of transportation and communication networks on farmers’ choice of market channels for paddy and wheat, and subsequently on the prices they receive from these channels. It is found that smallholder farmers sell more to informal channels i.e. local traders and input dealers, and typically receive lower prices from them compared to the government-set minimum support prices (MSP). The prices realized from the sales in regulated markets are also less than the MSP despite these being claimed to be more transparent in price discovery.

Understanding unethical behavior is essential to many phenomena in the real world. We carry out a field experiment in a unique setting that varies the levels of reciprocity and guilt in an ethical decision. A survey more than one year before the field experiment allows us to compare at the individual level stated unethical behavior with revealed behavior in the same situation in the field. Our results indicate a strong discrepancy between stated and revealed behavior, regardless of the specific treatment in the field experiment.

To reduce SDG tradeoffs in infrastructure provision, and to inform searches for SDG synergies, the authors show that roads’ impacts on Brazilian Amazon forests varied significantly across frontiers. Impacts varied predictably with prior development – prior roads and prior deforestation – and, further, in a pattern that suggests a potential synergy for roads between forests and urban growth. For multiple periods of roads investments, the authors estimate forest impacts for high, medium and low prior roads and deforestation. For each setting, census-tract observations are numerous.

The Chilean mussel aquaculture industry is a prime example of a thriving industry.  However, the industry growth rate, aquaculture concessions and market prices have stabilized signaling a shift in the industry from exponential growth to, if handled correctly, economic stability.  Here we used perception research, an efficient tool to inform on the implementation of management strategies, to provide policy makers with the tools necessary for the development of strategies that will aid in the sustainability of the industry through its current shift.  We assessed the perception

Small hydropower (SHP) has existed for more than a century in Colombia, and is gaining reserved interest as an option to mitigating climate change. In this paper we investigate the prospects for SHP in Colombia based on an analysis of economies-of-scale and learning-by-doing effects. We created an inventory of SHP plants realized in Colombia between 1900 and 2013, and focused on grid-connected SHP stations only. In the economies-of-scale part of our analysis we considered all SHP plants with a capacity lower than 20 MW.
