This study examines the cost-effectiveness of alternative methods for diffusing integrated pest management practices in Bangladesh. Methods compared include farmer field schools, field days, and extension agent visits. Farmer field school participants were more likely to adopt integrated pest management practices than recipients of messages from field days and agent visits. However, due to lower costs per participant, field days were the most cost-effective means for stimulating adoption of simpler practices and extension agent visits were the most cost-effective for extending more complex practices.  相似文献

Two experiments examined the effects of iterated polling and feedback on prediction accuracy for volatile world events using the Delphi paradigm. In both experiments, participants predicted rapidly changing geopolitical events. The first experiment occurred during the litigation surrounding the Clinton/Lewinsky affair in 1998. Results indicated that feedback improved individual and group accuracy for predictions of whether an event would occur. These types of predictions derived from group consensus were approximately 90% accurate, which was significantly higher than the average individual participant's accuracy. Neither polling nor feedback had much effect on time course predictions. The second experiment occurred during the American military action against the Taliban regime in Afghanistan in 2001. In Experiment 2, participants were polled three times to determine if increasing the number of iterated polls would improve Delphi accuracy. The results showed that accuracy improved from the first to the second poll but not from the second to the third. The groups predicted whether these scenarios would occur with approximately 75% accuracy, which was significantly higher than the accuracy of any individual participant. Once again, the Delphi procedure did not enhance time course predictions in Experiment 2.  相似文献

This paper discusses a recently published handbook on neuroeconomics ( and ) and extends the discussion to reasons why this newly emerging discipline should be of interest to behavioral accounting researchers. We evaluate the achieved and potential contribution of neuroeconomics to the study of human economic behavior, and examine what behavioral accounting researchers can learn from neuroeconomics and whether we should expect to see a similar sub-field emerge within behavioral accounting in the near future. We conclude that a separate sub-field within behavioral accounting is not likely in the near future due mostly to practical reasons. However, the behavioral accounting researcher would do well to follow research in this discipline closely, and behavioral accountants in the near future are likely to collaborate with neuroscientists and neuroeconomists on questions of mutual interest.  相似文献

This study examines how and why entrepreneurial passion for founding changes over time. In particular, we propose that in the founding phase of a venture's lifecycle entrepreneurs’ founding identity centrality will remain stable over time. We also propose, however, that in our sample and time period studied, entrepreneurs’ intense positive feelings for founding will decrease over time. On the basis of theories of positive illusion, self‐regulation and role theory, we further hypothesize that venture idea change, change in role ambiguity and entrepreneurs’ feedback‐seeking behaviour are factors that help explain the rate of change in entrepreneurs’ intense positive feelings for founding. Using a three‐wave longitudinal research design, we find that among a sample of 112 entrepreneurs’ identity centrality does not change over time, whereas intense positive feelings for founding decrease over time. Moreover, the more entrepreneurs change their venture ideas, the weaker their decrease in intense positive feelings. Further, we show that entrepreneurs who frequently seek feedback suffer less from reduced positive feelings in response to higher increases in role ambiguity as compared to entrepreneurs who seek less feedback.  相似文献

In this article, we study macroeconomic stabilization in the Economic and Monetary Union (EMU) using a dynamic game approach. With the aid of a stylized macroeconomic model, this article analyzes the transmission and interaction of national fiscal policies and monetary policy of the European Central Bank (ECB) in the EMU. A special focus is on the effects of labor market institutions in the participating countries and of the introduction of fiscal stringency criteria like those imposed in the Stability and Growth Pact.  相似文献

Technology analysis is important for technology management areas such as research and development strategy and new product development. So many studies on technology analysis have been used across a diverse array of fields. Most of these were based on patent analysis, which analyses patent documents using text mining and statistics. The studies on conventional patent analyses constructed models consisting of various independent variables (technologies) and one dependent variable. But in reality, we have to consider a model that includes several dependent variables at the same time, because most technologies influence each other. In this paper, we propose a methodology for patent analysis that reflects the various response technologies simultaneously. We perform multivariate multiple regression modelling in order to efficiently conduct our technology analysis. To show how our modelling can be applied to realistic context, we carry out a case study using the patent documents related to three-dimensional printing technology.  相似文献

This study involves an experiment where 73 Chief Audit Executives and deputy Chief Audit Executives determine the amount of adjustment required to correct a misstatement. We manipulate the financial reporting location of the misstatement (recognized vs. disclosed) and the level of audit committee expertise (high vs. low). The results indicate that financial reporting location has significant effects on internal auditors’ decisions to correct misstatements. Specifically, internal auditors are more willing to waive disclosed misstatements relative to recognized misstatements. Contrary to expectations, the results do not indicate that increased audit committee expertise and associated increases in audit committee members’ perceived powers cause internal auditors to be less willing to waive misstatements.  相似文献

We investigate an economy of heterogeneous agents that cannot specify all exogenous welfare-relevant events and consequently view the impact of unforeseen contingencies as utility shocks. In this setting we characterize an appropriate market equilibrium concept when securities can trade only on demand- and price-contingent events. We establish the existence of an equilibrium for a class of parametric models in which aggregating taste shocks across agents can lead to nonconsumption pricing factors. To fit the stylized facts, (i) non consumption factors must dominate the pricing kernel and contribute to the variation of the wealth-consumption ratio, (ii) markets must be incomplete and the set of claims that are traded endogenously determined, (iii) agents’ preferences with respect to unforeseen contingencies must be non-expected utility, and, (iv) although non-consumption pricing factors can be conditionally uncorrelated with aggregate consumption shocks, they must be correlated with shocks to expected consumption growth.  相似文献
