An Economic Analysis of Business Drinking : Evidence from a Lab-in-the-field Experiment

Alcohol consumption is an important component of business negotiations across many cultures, yet this behavior remains unmodeled and its potential implications untested. This paper is a step towards filling that gap. We develop a theory that combines guilt-aversion with a canonical alcohol myopia framework. Our GAAM (guilt aversion and alcohol myopia) model predicts that intoxication increases promise-making but has no effect on promise-breaking. We test these predictions using a prisoner's dilemma game with pre-play communication in a lab-in-the-field experiment. Among males, we find behavior consistent with predictions: intoxication promotes promise-making behavior but does not impact the rate at which promises are trusted or broken. Consequently, intoxication increases communication efficiency. We do not observe intoxication to impact female promise-making, trusting, or promise-breaking behaviors. This is consistent with previous empirical findings that females are substantially less sensitive than males to alcohol-induced myopia
