This paper investigates experimentally whether risk attitudes are stable across social contexts. In particular, it focuses on situations where some resource (for instance, a position, decision power, a bonus) has to be allocated between two parties: the decision maker can either opt for sharing the resource or for using a random device that allocates the entire prize to one of the two parties. ...

This study reports the results of a survey disseminated to Italian winegrowers and wine makers understand their attitude toward main climate risk factors on grape productions willingness proactively act in facing related consequences. A general noticeable concern about future effects change variability emerged, even with some differences between stakeholders operating different geographic clima...

Article history: Received 30 June 2011 Received in revised form September, 01, 2011 Accepted 06 September 2011 Available online 17 September 2011 Demand uncertainty obliges all participants through a supply chain to make decisions under uncertainty. These decisions extend across price, investment, production, and inventory quantities. We take account of competition between two supply chains und...

We apply nonparametric panel data kernel regression to investigate production risk, output price uncertainty, and risk attitudes of Polish dairy farms based on a firm-level unbalanced panel data set that covers the period 2004–2010. We compare different model specifications and different approaches for obtaining firm-specific measures of risk attitudes. We found that Polish dairy farmers are ri...

We introduce random evolving lotteries to study preference for non‐instrumental information. Each period, the agent enjoys a flow payoff from holding lottery that will resolve at terminal date. provide representation theorem non‐separable risk consumption preferences and use it characterize agents' attitude To address applications, we peak‐trough utilities aggregate trajectories of linearly but...

S expected utility theory does not distinguish between attitudes toward uncertainty (ambiguous probabilities) and attitudes toward risk (unambiguous probabilities). Both are explained in terms of nonlinear utility for money rather than properties of events per se, hence, the decision maker displays the same attitude toward all sources of risk and uncertainty. There is ample evidence that real d...

In this paper we investigate the effect of life expectancy on risk attitude in an artificial multi-agent world, which is a variant of the sugarscape [2]. Our basic approach is evolutionary in that we encode risk attitude as a gene within the agents that undergoes variation and selection and perform simulations to see the evolved (i.e., presumed optimal) values of this gene/attitude under differ...

The present study (a) examined the question of whether gender differences in hypothetical risk decisions might be socially facilitated by the presence of gender-homogenous groups and (b) investigated the conscious and non-conscious motivators of risk-taking through the application of both explicit and implicit measures of risk attitude. Using hypothetical choice dilemma items, no gender differe...

background to develop the culture of breastfeeding, it is needed to know the level of maternal knowledge. hence, the aim of this study was to evaluate maternal knowledge and attitude toward exclusive breastfeeding in six months after birth in shiraz, iran. materials and methods this was a cross-sectional study carried out on mothers who referred to health centers. four health centers were selec...

Observed and unobserved characteristics of an individual are often used by researchers to explain choices over the provision of environmental goods. One means for identifying what is typically an unobserved characteristic, such as an attitude, is through some data reduction technique, such as factor analysis. However, the resultant variable represents the true attitude with measurement error, a...
