Conflict, Evolution, Hegemony, and the Power of the State
Levine, David; Modica, Salvatore - National Bureau of Economic Research (NBER) - 2013
In a model of evolution driven by conflict between societies more powerful states have an advantage. When the influence of outsiders is small we show that this results in a tendency to hegemony. In a simple example in which institutions differ in their "exclusiveness" we find that these...

Directed Giving: Evidence from an Inter-Household Transfer Experiment
Batista, Catia; Silverman, Dan; Yang, Dean - National Bureau of Economic Research (NBER) - 2014
We investigate the determinants of giving in a lab-in-the-field experiment with large stakes. Study participants in urban Mozambique play dictator games where their counterpart is the closest person to them outside their household. When given the option, dictators do a large fraction of giving...

Field Experiments: A Bridge Between Lab and Naturally-Occurring Data
list, john - National Bureau of Economic Research (NBER) - 2007
Laboratory experiments have been used extensively in economics in the past several decades to lend both positive and normative insights into a myriad of important economic issues. This study discusses a related approach that has increasingly grown in prominence of late--field experiments. I...

The Nature of Excess: Using Randomized Treatments to Investigate Price Dynamics
list, john; Price, Michael K.; Al-Ubaydli, Omar - National Bureau of Economic Research (NBER) - 2010
This study explores empirically the price dynamics within two distinct market institutions - a double oral auction, which resembles modern asset markets, and a bilateral exchange market, which represents markets that have existed for centuries. To provide a theoretical basis to our...

What Happens in the Field Stays in the Field: Exploring Whether Professionals Play Minimax in Laboratory Experiments
Levitt, Steven; list, john; Reiley, David - National Bureau of Economic Research (NBER) - 2009
The minimax argument represents game theory in its most elegant form: simple but with stark predictions. Although some of these predictions have been met with reasonable success in the field, experimental data have generally not provided results close to the theoretical predictions. In a...

Checkmate: Exploring Backward Induction Among Chess Players
Levitt, Steven; list, john; Sadoff, Sally E. - National Bureau of Economic Research (NBER) - 2009
Although backward induction is a cornerstone of game theory, most laboratory experiments have found that agents are not able to successfully backward induct. Much of this evidence, however, is generated using the Centipede game, which is ill-suited for testing the theory. In this study, we...

Equilibrium Tax Rates and Income Redistribution: A Laboratory Study
Agranov, Marina; Palfrey, Thomas R. - National Bureau of Economic Research (NBER) - 2014
rates, inequality, and income redistribution. We also extend that model to incorporate social preferences in the form of … altruism and inequality aversion. The experiment varies the amount of inequality and the collective choice procedure to … determine tax rates. We report four main findings. First, higher wage inequality leads to higher tax rates. The effect is …

The Regulation of Prescription Drug Competition and Market Responses: Patterns in Prices and Sales Following Loss of Exclusivity
Cockburn, Iain M.; Aitken, Murray L.; Berndt, Ernst R.; … - National Bureau of Economic Research (NBER) - 2013
We examine six molecules facing initial loss of US exclusivity (LOE, from patent expiration or challenges) between June 2009 and May 2013 that were among the 50 most prescribed molecules in May 2013. We examine prices per day of therapy (from the perspective of average revenue received by retail...

Trust and Cheating
Giuliano, Paola; Guiso, Luigi; Butler, Jeffrey V. - National Bureau of Economic Research (NBER) - 2012
When we take a cab we may feel cheated if the driver takes an unnecessarily long route despite the lack of a contract or promise to take the shortest possible path. Is our decision to take the cab affected by our belief that we may end up feeling cheated? Is the behavior of the driver affected...

Trust, Values and False Consensus
Giuliano, Paola; Guiso, Luigi; Butler, Jeffrey - National Bureau of Economic Research (NBER) - 2012
Trust beliefs are heterogeneous across individuals and, at the same time, persistent across generations. We investigate one mechanism yielding these dual patterns: false consensus. In the context of a trust game experiment, we show that individuals extrapolate from their own type when forming...
