Explores response rate effects linked to the use of color photographs & design elements in a self-administered questionnaire printed on white paper, drawing on a 2001 study of homeowner preferences for watershed management practices in MI that utilized a stated choice type of stated preference survey. Overall, some evidence is found that the use of color photographs & color design elements may help increase response rates. Some attention is given to the relative printing costs. Although the increased cost per survey booklet might require some other avenue be pursued for raising response rate, if resources permitted, it is concluded that color would be used again. 1 Table, 19 References.

An increasing amount of investment has been devoted to protecting and restoring ecosystem services worldwide. The efficiency of conservation investments, including payments for ecosystem services (PES), has been found to be affected by biological, political, economic, demographic, and social factors, but little is known about the effects of social norms at the neighborhood level. As a first attempt to quantify the effects of social norms, we studied the effects of a series of possible factors on people's intentions of maintaining forest on their Grain-to-Green Program (GTGP) land plots if the program ends. GTGP is one of the world's largest PES programs and plays an important role in global conservation efforts. Our study was conducted in China's Wolong Nature Reserve, home to the world-famous endangered giant pandas and >4,500 farmers. We found that, in addition to conservation payment amounts and program duration, social norms at the neighborhood level had significant impacts on program re-enrollment, suggesting that social norms can be used to leverage participation to enhance the sustainability of conservation benefits from PES programs. Moreover, our results demonstrate that economic and demographic trends also have profound implications for sustainable conservation. Thus, social norms should be incorporated with economic and demographic trends for efficient conservation investments.

AbstractWe compare water quality valuation results from a probability sample and two opt‐in non‐probability samples, MTurk and Qualtrics. The samples differ in some key demographics, but measured attitudes are strikingly similar. For valuation models, most parameters were significantly different across samples, yet many of the marginal willingness to pay were similar across samples. Notably, for non‐marginal changes there were some differences by samples: MTurk values were always significantly greater than the probability sample, as were Qualtrics values for changes up to about a 20% improvement. Overall, the evidence is mixed, with some key differences but many similarities across samples.

As conditional cash transfer (CCT) programs spread in African countries, there is a need for well-designed programs that reflect their economic, institutional, political, and sociocultural circumstances. Using both qualitative and quantitative data analysis, this article examines the perspectives of beneficiaries, program managers, and community leaders regarding Ghana's CCT program. It addresses sociocultural attitudes toward poverty, perceptions of CCT as a poverty reduction strategy, and experiences with CCT implementation. Findings indicate favorable views of CCT but little support for giving money to the poor as a long-term poverty-alleviation strategy. Ghana's CCT program is seen as fair and popular, but current payment levels are viewed as inadequate, impractical, and unreliable.
