We experimentally study overbidding in contests and find that overbidding is significantly higher when subjects are given a large per-experiment endowment rather than when the endowment is given per-period. Risk-aversion and non-monetary utility of winning can partially explain our findings. 相似文献

The majority of economic decisions are forward-looking and thus involve expectations of future outcomes. Understanding the expectations that individuals have is thus of crucial importance to designing and evaluating policies in health, education, finance, migration, social protection, and many other areas. However, the majority of developing country surveys are static in nature and many do not elicit subjective expectations of individuals. Possible reasons given for not collecting this information include fears that poor, illiterate individuals do not understand probability concepts, that it takes far too much time to ask such questions, or that the answers add little value. This paper provides a critical review and new analysis of subjective expectations data from developing countries and refutes each of these concerns. We find that people in developing countries can generally understand and answer probabilistic questions, such questions are not prohibitive in time to ask, and the expectations are useful predictors of future behavior and economic decisions. The paper discusses the different methods used for eliciting such information, the key methodological issues involved, and the open research questions. The available evidence suggests that collecting expectations data is both feasible and valuable, suggesting that it should be incorporated into more developing country surveys. 相似文献

Trust is frequently a requirement for economic exchanges and the management of natural resources. Providing public information on past actions can promote trust through the formation of reputations. We developed an economic experiment to test whether a formal reputation mechanism could facilitate trusting relationships in the tradable grazing rights markets. Providing information to create formal public reputations for market participants did not increase the overall efficiency of the market. However, it did result in greater equality of income between partners, suggesting that participants showed more concern for their partners when they knew they would be rated. Even with public reputation information, bilateral relationships remained central to the market. Market failures in existing grazing rights markets may be better addressed by measures to increase communication between partners rather than simply relying on a formal reputation mechanism. 相似文献

Food consumption causes, together with mobility, shelter and the use of electrical products, most life cycle impacts of consumption. Meat and dairy are among the highest contributors to environmental impacts from food consumption. A healthier diet might have less environmental impacts. Using the E3IOT environmentally extended input output database developed in an EU study on Environmental Impacts of Products (EIPRO), this paper estimates the difference in impacts between the European status quo and three simulated diet baskets, i.e. a pattern according to universal dietary recommendations, the same pattern with reduced meat consumption, and a ‘Mediterranean’ pattern with reduced meat consumption. Production technologies, protein and energy intake were kept constant. Though this implies just moderate dietary shifts, impact reductions of up to 8% were possible in reduced meat scenarios. The slightly changed food costs do not lead to significant first order rebound effects. Second order rebounds were estimated by applying the CAPRI partial equilibrium model. This analysis showed that European meat production sector will most likely respond by higher exports to compensate for losses on the domestic meat market. Higher impact reductions probably would need more drastic diet changes. 相似文献

When evaluating the risks of future invasions, we often have sparse information on the likelihood that a species will arrive, establish and spread in a new environment, and on the potential impacts should this occur. Conventional risk assessment, therefore, is limited in providing guidance in managing the risk of non-indigenous species (NIS). However, risk management decisions must be made facing these uncertainties to avoid high and irreversible impacts.We develop an integrated ecological economic modeling and deliberative multi-criteria evaluation (DMCE) approach to support group decision-making in risk prioritization, using an example of ten NIS that could potentially impact Australian plant industries. This innovative approach seeks to combine the advantages of dynamic modeling with the benefits of DMCE in assessing and communicating uncertainty. The model unveils the complexity of the socio-ecological system of biological invasion, with a scenario analysis designed to interactively communicate scientific uncertainty to decision-makers. The DMCE provides a structured approach to identifying stakeholders' key concerns in addressing economic, social, and environmental dimensions of NIS risk explicitly. Functioning as a platform for risk communication, the DMCE also offers an opportunity for diverse views to enter the decision-making process and for the negotiation of consensus consensuses. 相似文献

The industrial landscape is becoming increasingly complex and dynamic, with innovative technologies stimulating the emergence of new applications, business models and industries. This paper presents a framework for mapping science and technology-based industrial emergence, in order to better understand the nature and characteristics of such phenomena, as a basis for improved strategy development. A full lifecycle perspective is included, emphasizing early stage phases associated with scientific and technological developments, together with key transitions between phases related to the conversion of scientific knowledge to technological capability, application, industrial activity and economic value. Roadmapping concepts are used to map industrial emergence phenomena from various perspectives that cover value creation and capture activities together with demand and supply-side factors. The framework has been tested by developing more than 25 diverse ‘emergence maps’ of historical industrial evolution, building confidence that the framework might be applicable to current and future emergence. Common characteristics of industrial emergence have been identified, including key events and milestones, focusing on a chain of demonstrators that delineate the various phases and transitions. 相似文献

The research applies the Material Values Scale (MVS; Richins and Dawson, 1992) cross-culturally by comparing materialism among Polish and American business students. Cultural differences (e.g., greater humanistic/collectivistic/Christian values in Poland) suggest lower MVS scores for Poles than for Americans. This prediction is consistent with the Local Culture hypothesis (i.e., that a strong local culture results in maintenance of traditional values in defense against global forces). Contrary to predictions, data suggest no Polish-American materialism differences, a finding consistent with the globalization hypothesis (i.e., increasing globalization leads to relatively uniform worldwide materialism). As a precursor to hypotheses testing, confirmatory factor analysis (CFA) tests the construct validity and cross-cultural validity of the MVS. The findings suggest substantial difficulties with the scale that limit the confidence in conclusions based on the scale. Based on these findings, future research discussion aims at developing a measure of materialism with potentially greater construct validity for cross-cultural applications. 相似文献

We examine determinants of different types of International New Ventures (INVs), namely Export Start‐up, Geographically Focused Start‐up, Multinational Trader, and Global Start‐up. Whereas this typology of INVs has been widely accepted in the literature, empirical testing of the determinants of INV types is largely missing. Our arguments build on the International New Venture Theory (INVT). Hypotheses generated from our framework are tested on 195 German high‐tech enterprises. Results show that growth orientation, prior international experience, knowledge intensity, product differentiation, and learning orientation distinguish significantly between the different INV types. 相似文献
