Research summary : Exit delay is an important problem for entrepreneurs and managers alike, yet relatively little is known about its causes. We conduct a laboratory experiment in which optimal exit is well defined, and in which a treatment group with equity stakes—the actual cash flows of a firm and decision rights over its continuation—is compared to a control group whose compensation is based solely on its assessment of the firm's profitability. While treatment group participants make exit decisions that are nearly optimal given their beliefs, their beliefs are significantly distorted relative to the control group. The pattern of distortion is consistent with confirmatory bias and motivated reasoning. A fundamental finding of our study is that incentives may not only affect behavior, but belief formation as well. Managerial summary : Managers and entrepreneurs frequently destroy significant value by failing to shut down underperforming businesses in a timely manner. To address this problem, we must understand the mechanisms causing exit delay. We examine behavioral mechanisms causing delay through a laboratory experiment in which subjects make decisions about when to exit a failing venture. We find that “equity stakes”—receiving the firm's cash flows and having decision rights over exit—cause participants to discount negative performance information, retain overly optimistic beliefs, and delay exit. By contrast, participants without these high‐powered incentives exit nearly optimally. Our findings suggest ways to reduce exit delay in managerial settings, including implementing automated decision rules, removing equity‐based compensation, and recruiting managers less susceptible to knowledge overconfidence, a trait associated with exit delay.

European farmland hosts a species assemblage of animals and plants which have undergone declines through the late twentieth and early twenty-first centuries, at least partly as a result of increased productivity. Further increases in human populations, changes in availability and cost of raw materials, policy constraints, price volatility and climatic changes will further drive greater efficiency and high yields in agriculture, with the risk of further adverse environmental impacts. We assess the effects of different management priorities (production-driven cropping vs. wildlife-friendly farming) at an arable farm in eastern England on food production, greenhouse gas (GHG) emissions and biodiversity. We modelled one actual and three alternative cropping scenarios using actual yields from the farm over 13 years, to calculate total yields and those foregone for agri-environmental measures. We measured crop yields, relative abundance of 19 farmland bird species, and CO2 and N2O emissions related to crop production. Removing up to 10.5% of land from production coupled with a more diverse rotation (including legumes) resulted in a large increase in breeding birds (177%) and reduction of 9.4% in GHG emissions at the cost of 9.6% of food energy. Food protein lost was only 2.9%. A smaller increase in bird numbers of 50% could be achieved at a much smaller cost to yield (~1.7% energy or protein) but with correspondingly smaller emissions reductions (1.2%). Results are discussed within the context of continued biodiversity loss to agriculture, increasing food demand and changing diets. 相似文献

Grassland conversion to row-crop production in the north central United States has been a growing threat to socio-economic and environmental sustainability for producers, conservationists, and policy-makers alike. We used a system dynamics model of the region to forecast agriculturally driven land transformation through mid-twenty-first century. The base-case scenario projection showed that farmland area continued to increase, from under 200,000?km2 to over 230,000?km2. Unmitigated, the soil environmental risk (SER) of such changes reached conservative estimates of Dust Bowl-era externalities. Systems analyses show that reducing livestock production costs, doubling conservation compliance requirements, and livestock–cropping integration had the largest impact on grassland conservation and mitigating SER. The largest SER effects came from eliminating conservation incentives or raising cultivation incentives, despite improvements in reduced tillage and enhanced agronomy. Several system archetypes were identified within the policy scenarios: ‘fixes that backfire’ and ‘success-to-the-successful’. For scenarios creating favourable impacts, time delays caused some behaviours to worsen before positive gains were realized. If implemented, patience and persistence to ensure that these scenarios reach their full potential will be necessary. Our scenarios provide quantitative forecasts around measures for sustainable intensification. These projections can aid regional stakeholders in enhancing discussions currently taking place about sustainable agriculture in the region. 相似文献

Despite growing interest in ethical consumer behaviour research, ambiguity remains regarding what motivates consumers to purchase ethical products. While researchers largely attribute the growth of ethical consumerism to an increase in ethical consumer concerns and motivations, widened distribution (mainstreaming) of ethical products, such as fairtrade, questions these assumptions. A model that integrates both individual and societal values into the theory of planned behaviour is presented and empirically tested to challenge the assumption that ethical consumption is driven by ethical considerations alone. Using data sourced from fairtrade shoppers across the UK, structural equation modelling suggests that fairtrade purchase intention is driven by both societal and self-interest values. This dual value pathway helps address conceptual limitations inherent in the underlying assumptions of existing ethical purchasing behaviour models and helps advance understanding of consumers’ motivation to purchase ethical products. 相似文献

In this study, we use experimental markets to assess the effect of the Security and Exchange Commission's (SEC's) new independence rule on investors' perceptions of independence, investors' payoff distributions, and market prices. The new rule requires client firms to disclose in their annual proxy statements the amount of nonaudit fees paid to their auditors. The new disclosure is intended to inform investors of auditors' incentives to compromise their independence. Our experimental design is a 2 3 between‐subjects design, where we control the presence (unbiased reports) or absence of auditor independence in fact (biased reports). While independence in fact was not immediately observable to investors, we controlled for independence in appearance by varying the public disclosure of the extent of nonaudit services provided by the auditor to the client. In one market setting, investors were not given any information about whether the auditor provided such nonaudit services; in a second setting, investors were explicitly informed that the auditor did not provide any non‐audit services; and in a third setting, investors were told that the auditor provided nonaudit services that could be perceived to have an adverse effect on independence in fact. We found that disclosures of nonaudit services reduced the accuracy of investors' beliefs of auditors' independence in fact when independence in appearance was inconsistent with independence in fact. This then caused prices of assets to deviate more from their economic predictions (lower market efficiency) in the inconsistent settings relative to the no‐disclosure and consistent settings. Thus, disclosures of fees for nonaudit services could reduce the efficiency of capital markets if such disclosures result in investors forming inaccurate beliefs of auditor independence in fact ‐ that is, auditors appear independent but they are not independent in fact, or vice versa. The latter is the maintained position of the American Institute of Certified Public Accountants (AICPA), which argued against the new rule. Further research is needed to assess the degree of correspondence between independence in fact and independence in appearance. 相似文献

This paper considers the effect of child care costs on two labor market outcomes for single mothers—whether to work for pay and whether to receive welfare. Hourly child care expenditures are estimated using data drawn from the 1992 and 1993 panels of the Survey of Income and Program Participation (SIPP). These expenditures are then used to predict the probability of welfare recipiency and employment. While the direction and significance of key variables are robust to changes in specification, the quantitative results are found to be sensitive to identification restrictions. All results show a substantial positive effect of child care costs on welfare recipiency, with the child care price elasticity of welfare recipiency varying from 1.0 to 1.9. Similarly, we find a significant negative effect of child care price on employment with elasticity estimates from -.3 to -1.1, showing that controlling for the welfare choice does not reduce the price elasticity of employment found in other studies. 相似文献

An increasing number of patients use the internet to obtain information about health. Although some information is available about how health professionals use the internet, little is known about how patients utilize this information. Some patients may actively seek information to assume more responsibility for their health. However, others may feel obliged to do so because of failing confidence in health care provision. Health professionals have the potential to assist patients to make sense of health information from the internet; however, they may not necessarily welcome this role. This study aims to evaluate patients’ use of such information in a primary care setting. The sample consisted of adult patients (n = 851) from two general practice populations at different levels of the socio‐economic spectrum in South Wales (UK). Patients were surveyed by questionnaire about the health information they use, including the internet. The majority of patients preferred to use their general practitioner as the main source of health information. The internet was jointly the second preferred source for information about an illness (6%). Just over half (51%) of patients in this study had access to the internet, of which about half use it to access health information. Just under a quarter (24%, n = 55) of health internet users had discussed information accessed from the internet during a subsequent consultation with a health professional. Of these, three‐quarters felt more prepared and able to participate in decision‐making about treatments. This study provides a greater understanding of how patients are making use of health‐related information from the internet. These findings can be used to help prepare health care professionals for dealing appropriately with internet‐informed patients. 相似文献

ABSTRACTWe describe the creation of the Global Multi-Region Input–Output (MRIO) Lab, which is a cloud-computing platform offering a collaborative research environment through which participants can use each other’s resources to assemble their own individual MRIO versions. The Global MRIO Lab’s main purpose is to harness and focus previously disparate resources aimed at compiling large-scale MRIO databases that provide comprehensive representations of interregional trade, economic structure, industrial interdependence, as well as environmental and social impact. Based on the operational Australian Industrial Ecology Lab, a particularly important feature of this cloud environment is a highly detailed regional and sectoral taxonomy called the ‘root classification’. The purpose of this root is to serve as a feedstock from which researchers can choose any combination of regions and economic sectors to form a model of the economy that is suitable to address their particular research questions. Thus, the Global MRIO Lab concept enables enhanced flexibility in MRIO database construction whilst at the same time saving resources and avoiding duplication, by sharing time- and labour-intensive tasks amongst multiple research teams. We explain the concept, architecture, development and preliminary results of the Global MRIO Lab, and discuss its ability to continuously deliver some of the most prominent world MRIO databases. 相似文献

The relative cost of owning and renting housing and housing affordability have been clearly established as important determinants of home ownership. But the roles of marital status and history have been largely ignored. In this paper we show that both current marital status and past history affect ownership. Past history matters because wealth accumulation is greater among couple households than singles owing largely to economies of scale in housing consumption. Moreover, wealth is lost upon divorce. In effect, past marital history affects the affordability of owner housing. This result is shown in the estimation of model explaining wealth, leverage and tenure choice using Australian datasets. 相似文献
