The theory of games against nature relies on complete preferences among all conceivable acts (case 1). Aumann and Drèze (Am Econ J Microecon 1(1):116,(2009) consider situations where preferences are defined only for a given set of acts (case 2).We extend these results to situations where (i)...

This paper presents some new stochastic dominance (SD) criteria for ranking transformations on a random variable, which is the first time that this is done for transformations under the discrete framework. By using the expected utility theory, the authors first propose a sufficient condition for...

A counterexample is presented to show that the sufficient condition for one transformation dominating another by the second degree stochastic dominance, proposed by Theorem 5 of Levy (Stochastic dominance and expected utility: Survey and analysis, 1992), does not hold. Then, by restricting the...

Principled capitalism has been proposed as a replacement for liberal capitalism. Moral principles should be driving our individual and collective decisions rather than utility and profit. A new unit called an oblig is suggested as a measure of the amount of the substance of the "stuff" that...

Almost stochastic dominance is a relaxation of stochastic dominance, which allows small violations of stochastic dominance rules to avoid situations where most decision makers prefer one alternative to another but stochastic dominance cannot rank them. The authors first discuss the relations...

Survey experiments are an important tool to measure policy preferences. Researchers often rely on the random assignment of policy attribute levels to estimate different types of average marginal effects. Yet, researchers are often interested in how respondents trade-off different policy...

In Germany and many other countries, financial advisors are required by law to assess their clients' risk preferences in order to help them make informed and appropriate investment decisions. Most institutions that provide financial advice-banks, for instance-carry out this assessment using just...

In vielen Ländern der Welt, Deutschland eingeschlossen, sind Finanzberater (hier Personen, die Privatanleger bei Finanzanlagen beraten) heutzutage gesetzlich verpflichtet, die Risikoeinstellung ihrer Kunden zu erfassen, um ihnen dabei zu helfen, die passendste Anlageentscheidung zu treffen. Die...

Fatalities from illegal immigration from Africa to Europe are a grave reality. The phenomenon represents a major challenge for both home and host countries. Nonetheless, almost nothing is known about how the motivations of potentially illegally migrating individuals are formed. This paper aims...
