background and purpose: despite extensive research on family planning and education, reproductive behavior of high-risk couples for thalassemia remains a major concern among medical professionals. this study aimed to evaluate the knowledge and attitude of carrier couples for transfusion-dependent thalassemia major (tdtm). methods: this case-control study was conducted 327 carrier couples for th...

Does risk attitude (aversion or attraction) vary with the level of the income at risk? About half of our subjects chose to insure all levels, whereas another half chose instead not to insure low levels, but to insure high levels.

We propose the use of HTN planning for risk-sensitive planning domains. We suggest utility functions that reflect the risk attitude of compound tasks, and adapt a best-first search algorithm to take such utilities into account.

Introduction: Medical error reporting has been recognized as the cornerstone of patient safety practices; however, healthcare personnel often do not report errors. In order to increase the frequency of error reporting, it is important to understand both the healthcare workers' attitudes towards reporting, as well as what they perceive as barriers. Aim: The aim of this literature review was to i...

Nudging people to make good investments is necessary because of low financial literacy. One type of advice concerns allocation to risky vs. safe investments. Financial advisors generally assume that people differ in their risk attitudes, and they sometimes try to assess these attitudes with questionnaires about risks. But attitudes toward risks are influenced by many factors that are irrelevant...

In this paper we examine how risk attitudes change with age. We present participants from age 5 to 64 with choices between simple gambles and the expected value of the gambles. The gambles are over both gains and losses, and vary in the probability of the non-zero payoff. Surprisingly, we find that many participants are risk seeking when faced with high-probability prospects over gains and risk...

We study partnership contracts under uncertainty but with clauses that admit downstream flexibility. The focus is on effects of flexibility on the synergy set, the core, of the contract. In a partnership context the value of flexibility is captured by the partners who own the right to exercise. On one side, there are cooperative options, which are exercised jointly and in the interest of maximi...

This paper uses data on real and perceived cancer risks and cancer screening behavior to test whether education helps to make better informed health decisions. I propose that if educated individuals are better informed, then they will be more likely to incorporate variation in risk factors when they report their personal cancer risk. As risk varies, they will also react more strongly by adoptin...

1 We are grateful to Steve Matthews for suggesting the approach taken in this study, and to Eric Maskin for his encouraging comment. Abstract This paper concerns the e¢ cient sale of an indivisible risky asset and the e¤ects of changing risk in a setting where buyers exhibit heterogeneous risk preferences. The model allows asymmetric and interdependent values and types. Under certain conditions...

Classic financial agency theory recommends compensation through stock options rather than shares to induce risk neutrality in otherwise risk averse agents. In an experiment, we find that subjects acting as executives do also take risks that are excessive from the perspective of shareholders if compensated through options. Compensation through restricted company stock reduces the uptake of exces...
