Abstract Increasingly globalized communication networks in the modern world may influence traditional patterns of linguistic change: contrast to an orderly sequential pathway change, more recently a number “mega trends” have been identified, which accelerate simultaneously time and space. The rise obviously within cohort adverbs evidentiality— naturally, evidently, clearly, course —may be one s...

Abstract We consider assignment problems where individuals are to be assigned at most one indivisible object and monetary transfers not allowed. provide a characterization of rules that Pareto efficient, nonbossy, implementable in obviously strategy‐proof (OSP) mechanisms. As corollaries our result, we obtain OSP‐implementable fixed priority top trading cycles (FPTTC) rules, hierarchical exchan...

Many two-sided matching markets, from labor markets to school choice programs, use a clearinghouse based on the applicant-proposing deferred acceptance algorithm, which is well known to be strategy-proof for the applicants. Nonetheless, a growing amount of empirical evidence reveals that applicants misrepresent their preferences when this mechanism is used. This paper shows that no mechanism th...

An outcome is ambiguous if it is an incomplete description of the probability distribution over consequences. An incomplete description is identified with the set of probabilities that satisfy the incomplete description. A choice problem is ambiguous if the decision maker is choosing between incompletely described outcomes, that is, between sets of probabilities. This paper develops the theory ...

BACKGROUND Although it is illegal to sell alcohol to an individual who appears obviously intoxicated, several recent studies show that the propensity of these types of sales is high. Our study further assesses the propensity of alcohol establishments to sell alcohol to obviously intoxicated patrons. In addition to providing more recent data (2001) on pseudo-intoxicated purchase attempts at Midw...
