Abstract We consider an expected utility maximization problem where the function is not necessarily concave and time horizon uncertain. establish a necessary sufficient condition for optimality general non-concave in complete financial market. show that concavification approach of to deal with non-concavity, while being still applicable when stopping respect market filtration, leads sub-optimal...

stem reserve remobilization is very important to keep the grain yield in wheat under terminal drought but the importance of this mechanism is unclear under terminal salinity. in this research stem reserve remobilization under terminal salinity were studied in greenhouse on four genotypes no14 and no49, different in remobilization, and bam as salt-tolerant and ghods as salt-sensitive cultivars. ...

Who Performs Better under Time Pressure? Results from a Field Experiment We investigate whether and how time pressure affects performance. We conducted a field experiment in which students from an Italian University are proposed to choose between two exam schemes: a standard scheme without time pressure and an alternative scheme consisting of two written intermediate tests, one of which to be t...
