Risk,learning, and technology adoption   总被引:1,自引:0,他引:1       下载免费PDF全文
This article explores how decision makers learn and use information, with an application to the adoption of biotechnology in agriculture. The empirical analysis relies on experimental and survey data measuring risk preferences, learning processes, and the adoption of genetically modified (GM) seeds among U.S. grain farmers. While controlling for risk aversion, we link individual learning rules with the cognitive abilities of each decision maker and their actual GM adoption decisions. We find evidence that very few individuals are Bayesian learners, and that the population of farmers is quite heterogeneous in terms of learning rules. This suggests that Bayesian learning (as commonly assumed in the analysis of agricultural technology adoption) is not an appropriate characterization. In addition, we do not find a strong relationship between observed learning styles and the timing of GM seed adoption. To the extent that learning is a key part of the process of technology adoption, this suggests the presence of much unobserved heterogeneity in learning among farmers.  相似文献

While in the domestic work environment, minorities are more likely to have turnover intentions and receive lower performance evaluations; the findings in this study indicate that minorities, when deployed overseas, receive higher performance evaluations than Caucasian expatriates. For Caucasian expatriates, cultural adaptability improved interaction adjustment and reduced turnover intentions, but not to the extent to which minority status improved these outcomes. These findings suggest that studying minority expatriates is a critical but overlooked factor in understanding expatriate success.  相似文献

Objectives:

To understand the impact of nocturnal and daytime non-severe hypoglycemic events on healthcare systems, work productivity and quality of life in people with type 1 or type 2 diabetes.

Methods:

People with diabetes who experienced a non-severe hypoglycemic event in the 4 weeks prior to the survey were eligible to participate in a nocturnal and/or daytime hypoglycemia survey. Surveys were conducted in Argentina, Australia, Brazil, Israel, Mexico and South Africa.

Results:

In total, 300 respondents were included in nocturnal/daytime hypoglycemia surveys (50/participating country/survey). All respondents with type 1 diabetes and 68%/62% (nocturnal/daytime) with type 2 diabetes were on insulin treatment. After an event, 25%/30% (nocturnal/daytime) of respondents decreased their insulin dose and 39%/36% (nocturnal/daytime) contacted a healthcare professional. In the week after an event, respondents performed an average of 5.6/6.4 (nocturnal/daytime) additional blood glucose tests. Almost half of the respondents (44%) reported that the event had a high impact on the quality of their sleep. Among nocturnal survey respondents working for pay, 29% went to work late, 16% left work early and 12% reported missing one or more full work days due to the surveyed event. In addition, 50%/39% (nocturnal/daytime) indicated that the event had a high impact on their fear of future hypoglycemia.

Conclusions:

The findings suggest that nocturnal and daytime non-severe hypoglycemic events have a large financial and psychosocial impact. Diabetes management that minimizes hypoglycemia while maintaining good glycemic control may positively impact upon the psychological wellbeing of people with diabetes, as well as reducing healthcare costs and increasing work productivity.  相似文献

This study is examines the dynamics in prices paid in “pay-what-you-want” situations over multiple customer–seller transactions on an individual customer level. The analysis of potential dynamism in prices paid allows for an assessment of the profitability of pay-what-you-want pricing for sellers of frequently bought products and services. To empirically validate the framework, the authors conduct a field study that focuses on the aggregate and individual dynamics in prices paid over customers’ multiple purchases. Using latent growth modeling, the authors find significant but declining decreases in prices paid. Further, they identify stable individual and relational difference factors which predict steeper or more gradual declines in prices paid. Customers’ individual preferences for fairness and price consciousness as well as their overall satisfaction with the seller alleviate price declines. The authors discuss the practical and theoretical implications of these findings.  相似文献

This article presents a trust‐centered, integrated model for achieving educational excellence in the higher education industry with focus on governing boards and strategies for academic quality and financial performance. The discussion includes leadership themes and strategies on development of teacher‐leaders, creating a culture of shared leadership and effective governance for performance outcomes, robust evaluations of student‐learning assessments for continuous improvement, and strategic leadership in the implementation of high‐quality programs. Perceptions of trust form the foundation of the integrated model with influences of personality, culture, motivation, values, reliability, competence, and intuition. Trust among board trustees is essential for creating collaborative environments for innovative change and educational performance excellence. Collaborative environments promote a sense of shared leadership and governance to encourage innovation and performance excellence at all levels within the educational institution.  相似文献

We investigate co-operative innovative activity in four major European countries, France, Germany, Spain and the UK, using internationally comparable firm-level data for manufacturing and service sectors. We examine the roles of knowledge flows, cost- and risk-sharing and public financial support in firms’ decisions to collaborate. Our results suggest that firms which place greater value on external information flows are more likely to co-operate with the research base than with other firms and that firms facing appropriability problems are more likely to co-operate with the research base and with upstream and downstream firms than with direct competitors. We find evidence for Spain to suggest that firms collaborate to overcome risks and financial constraints. We also find that receipt of public support is positively related to undertaking collaborative innovation. In line with the focus of policy, this relationship is strongest for co-operation with the research base.  相似文献

Starting from the failure of the R&D–patents traditional relationship, when time-series and/or within-industry dimensions are included in the empirical analysis, the present work tries to contribute to the empirical literature from two directions. First, it performs a Granger causality test based on the theoretical presumption of a reverse patents→R&D link as an explanation for the failure of the traditional relationship. Second, assuming the reverse patents–R&D causality, we test and interpret the lag structure of such a relationship which shows the effective patent life that firms can expect within the two Schumpeterian patterns of innovations they belong to. In the light of the effective patent life, we offer a further explanation of innovation persistence which overturns the findings of the existing literature on persistence.  相似文献

ABSTRACT

Although the gender gap in incomes has been extensively researched, scant attention has been paid to the gender wealth gap. This paper compares the gender wealth gap in Australia with that of Switzerland. Using data from the 2010 Household, Income, and Labour Dynamics in Australia (HILDA) and the 2012 Swiss Household Panel (SHP), this study attributes the gender wealth gap to differences in permanent income and education. Furthermore, the gender wealth gap is much larger in Switzerland than in Australia. The study links this finding to the type of wealth held by individuals in these two countries. Differences in wealth accumulation among women in Switzerland and Australia are likely to be linked to the housing market and to family policies for (single) mothers.  相似文献

Charitable organizations are increasingly using sport events as an approach to generate funds and raise awareness. Researchers have suggested that sport events are particularly attractive to volunteer fundraisers because they provide an opportunity to engage in two meaningful activities simultaneously. The purpose of this study was to address this largely untested proposition by assessing the presence of various segments of participants based on an identity defined in part by fundraising for the cause and/or cycling. Additionally, how these profiles differed based on the amount of funds raised, length of participation with the event, and basic demographic variables were also examined. The results suggest that four different segments existed, labeled event enthusiasts, cause fundraisers, road warriors, and non-identifiers. These segments differed in the amount of funds raised and their length of involvement with the event. As such, this study demonstrates the value of segmenting volunteer fundraisers based on event-related identities.  相似文献
