| Abstract: | We compare, on the basis of a procedurally fair "provision point" mechanism, bids for a public project from which some gain and some lose with bids for a less efficient public project from which all gain. In the main treatment, participants independently decide which one, if any, of the public projects should be implemented. We also run control treatments where only one of the two projects can be implemented. We find that (a) mixed feelings per se do not affect bidding behavior, and (b) the provision frequency of the project that raises mixed feelings declines significantly when it faces competition from the public good. |

| Abstract: | Team success relies on assigning team members to the right tasks. We use controlled experiments to study how roles are assigned within teams and how this affects team performance. Subjects play the takeover game in pairs consisting of a buyer and a seller. Understanding optimal play is very demanding for buyers and trivial for sellers. Teams perform better when roles are assigned endogenously or teammates are allowed to chat about their decisions, but the interaction effect between endogenous role assignment and chat unexpectedly worsens team performance. We argue that ego depletion provides a likely explanation for this surprising result. |

| Abstract: | The purpose of this guideline is to provide suggestions on designing impact evaluations for agricultural projects, particularly projects that directly target farmers, and seek to improve agricultural production, productivity and profitability. Specific issues in evaluating agricultural projects are addressed, including the need to use production-based indicators and to carefully consider indirect or spillover effects that are common in agricultural projects. |

| Abstract: | In this paper, we evaluate the impact of research grants on the amount of collaboration, among scientific researchers in Argentina. We find a positive and significant impact of funding on collaboration, which is measured in terms of the number of co-authors for publications in peer-reviewed journals. In particular, we find a significant impact of the grants for funded researchers both on the size of their ego network, and on their 2-step indirect links, measured by the number of direct and 1-step indirect co-authors. We also find evidence that this impact was driven by the results of funded researchers at the upper tail of the distribution of collaboration outcomes. |

| Abstract: | This paper discusses recent trends in investment in the oil sector, amid new challenges for national and international oil companies in an increasingly supply-constrained environment. After more than a decade of stagnant investment rates, nominal investment has picked up sharply over the three years ending in 2007, but soaring costs (including from higher tax rates and royalties) meant that investment growth was minimal in real terms. The paper performs econometric tests using the Arellano-Bond GMM technique. It finds that `below ground¿ risks are statistically very important in deterring real investment. Companies are taking on increasingly complex geological challenges, which are putting upward pressure on production costs and are leading to greater project delays compared to the past. As many of these factors are expected to persist, supply constraints are likely to remain a dominant factor behind oil price fluctuations during the next several years. |

| Abstract: | ocial Discount Rate (SDR) is a very crucial policy parameter in public project appraisals due to its resource allocation impacts. This study estimates an SDR for Turkey using the Social Time Preference Rate (STPR) approach. The elasticity of the marginal utility consumption, which is the most important component of the STPR, is estimated econometrically from a demand for food approach during the period of 1980-2008. The overall result indicates that the SDR for Turkey is 5.06%. The European Union requires evaluation of the publicly supported commercial projects in terms of the SDR; hence the findings from this study can be used as a useful policy measurement for a full EU member candidate country, Turkey. |

| Abstract: | Municipal solid waste management continues to be a major challenge for local governments in both urban and rural areas across the world, and one of the key issues is their financial constraints. Recently an economic analysis was conducted in Eryuan, a poor county located in Yunnan Province of China, where willingness to pay for an improved solid waste collection and treatment service was estimated and compared with the project cost. This study finds that the mean willingness to pay is about 1 percent of household income and the total willingness to pay can basically cover the total cost of the project. The analysis also shows that the poorest households in Eryuan are not only willing to pay more than the rich households in terms of income percentage in general, but also are willing to pay no less than the rich in absolute terms where no solid waste services are available; the poorest households have stronger demand for public solid waste management services while the rich have the capability to take private measures when public services are not available. |

| Abstract: | While polluted surface water is encountered across most of China, few economic valuation studies have been conducted on water quality changes. Limited information about the economic values associated with those potential water quality improvements or deteriorations is a disadvantage for making proper choices in water pollution control and clean-up activities. This paper reports an economic valuation study conducted in Yunnan, China, which aims to estimate the total value of a real investment project to improve the water quality of Lake Puzhehei by one grade level. Located in Qiubei County, which is far from large cities, the lake has been experiencing fast water quality deterioration in the past years. A conservative estimation strategy shows that on average a household located in Qiubei County is willing to pay about 30 yuan per month continuously for 5 years for water quality improvement, equivalent roughly to 3 percent of household income. The elasticity of willingness-to-pay with respect to income is estimated to be 0.21. The economic rate of return of the proposed project is estimated to be 18 percent, indicating a strong demand and high efficiency of investment in water quality improvement in China. This study also demonstrates that previous knowledge about water quality changes and the project may have a significant positive impact on people's valuation, and that the interviewer effect on valuation can be negative. |
