We develop a structural model to analyze the effects of banning advertising on demand, supply and market equilibria in junk food markets. We use transaction level data on the potato chips market and find that banning advertising does not lead to a reduction in demand because, while banning advertising reduces consumers’ taste for junk food, it also toughens price competition, leading to lower p...

The field of social psychology explores how a person behaves within the context of other people. The social context can play a substantive role in non-market allocation decisions given peoples choices and values extend beyond the classic market-based exchange institution. Herein we explore how social psychology has affected one aspect of environmental economics: preference elicitation through s...

In this study, we propose a value-based management approach for assessing the potential for process improvements enabled by an information technology (IT) solution. Based on activity based management concepts, we perform a granular, process level analysis on workflow structure and associated resource consumption to provide quantifiable measures of potential improvement prior to system implement...

As a consequence, bad rainy seasons have a massive impact on crop yield and regularly entail food crises. Traditional insurances based on crop damage assessment are not available because of asymmetric information and high transaction costs compared to the...

METHODS Between April 2003 and September 2006 we conducted a questionnaire-based evaluation in our oocyte donor prog...

Abstract Prioritarianism is a variant of utilitarianism. It differs from utilitarianism in that benefiting individuals matters more the worse off these are. On this view, there are two standard ways handling risky prospects: Ex-Post adjusts for prioritizing final outcomes and then values prospects by expectation sum total those adjusted values, whereas Ex-Ante on each individual's expectations....

a r t i c l e i n f o This paper proposes a new method for determining the upper bound of any investment strategy's maximum profit , applied in a given time window [0,T]. This upper bound is defined once all the prices are known at time T and therefore represents the ex-post maximum efficiency of any investment strategy determined during the relevant time interval. This approach allows us to ga...
