Abstract: In this paper, we analyze water demand by urban households in Rwanda who currently lack a piped connection into their home. The analysis uses data from a cross-sectional survey. The results show that public taps are the most widely used water source and that the demand for water from this source is more inelastic than that for water from other water sources. Although some households combine different sources of water, the majority in the sample uses only one source.

Abstract: Gendered food security gaps between female- and male-headed households (FHHs and MHHs) can be decomposed into two sets of components: those explained by observable differences in levels of resource use, and those due to unobserved differences affecting the returns to the resources used. Employing exogenous switching ordered probit and binary probit regression models, this paper examines the gendered food security gap and its causes in rural Malawi.

Abstract: We compare of  the  performance  of  emission  taxes  between  Colombia  and  Sweden in an experimental  setting  where  subjects are regulated  through  environmental  taxes  and  had  to decide on emission levels, compliance behavior, and adoption of an environmentally friendly technology.  Our  design  allows  us  to  analyze  the  role of variations  in  the  stringency  of  the policy  enforcement&nbsp

Abstract: In this paper, we conduct a high stake experiment in rural China to investigate the determinants of individual and joint decisions regarding intertemporal choices, and estimate the relative influence of spouses on the joint decisions. We use the Convex Time Budget experimental method to elicit individual and joint decisions on how much money to allocate to an early and a later date. We find that the rates of return have significant effects on the decisions, yet both individual and joint decisions exhibit present-biased time preferences.

Abstract: We examine whether and to what extent joint choices are more or less patient and time - consistent than individual choices in households. We use data from an artefactual field experiment where both individual and joint time preferences were elicited. We find a substantial shift from individual to joint household decisions. Interestingly, joint decisions do not only generate beneficial shifts, i.e., patient and time - consistent shifts. On the contrary, a majority of the observed shifts are impatient and time - inconsistent shifts.

Abstract: We augment a standard dictator game to investigate how preferences for an environmental project relate to willingness to limit others’ choices. We explore this issue by distinguishing three student groups: economists, environmental economists, and environmental social scientists. We find that people are generally disposed to grant freedom of choice, but only within certain limits. In addition, our results are in line with the widely held belief that economists are more selfish than other people.

Abstract: Attitudes towards risk and uncertainty have been indicated to be highly context-dependent, and to be sensitive to the measurement technique employed. We present data collected in controlled experiments with 2,939 subjects in 30 countries measuring risk and uncertainty attitudes through incentivized measures as well as survey questions. Our data show clearly that measures correlate not only within decision contexts or measurement methods, but also across contexts and methods.

Abstract: We investigate the relationship between social class belonging and contributions to local public goods. By utilizing the social class classifications in Colombia and an experimental design based on the strategy method, we can both study contributions to public goods and classify subjects into contribution types. We find similar contribution levels between high and medium-low social classes and also similar distributions of contributor types. However, low social class members conditionally contribute a significantly higher level than high social class members.
