Political Dynasties

We study political dynasties in the United States Congress since its inception in 1789. We document historic and geographic patterns in the evolution and profile of political dynasties, study the extent of dynastic bias in legislative politics versus other occupations, and analyze the connection between political dynasties and political competition. We also study the self-perpetuation of political elites. We find that legislators who enjoy longer tenures are significantly more likely to have relatives entering Congress later. Using instrumental variables methods, we establish that this relationship is causal: a longer period in power increases the chance that a person may start (or continue) a political dynasty. Therefore, dynastic political power is self-perpetuating in that a positive exogenous shock to a person's political power has persistent effects through posterior dynastic attainment. In politics, power begets power.

"Do the Right Thing:" The Effects of Moral Suasion on Cooperation

The use of moral appeals to affect the behavior of others is pervasive (from the pulpit to ethics classes) but little is known about the effects of moral suasion on behavior. In a series of experiments we study whether moral suasion affects behavior in voluntary contribution games and mechanisms by which behavior is altered. We find that observing a message with a moral standard according to the golden rule or, alternatively, utilitarian philosophy, results in a significant but transitory increase in contributions above the levels observed for subjects that did not receive a message or received a message that advised them to contribute without a moral rationale. When players have the option of punishing each other after the contribution stage the effect of the moral messages on contributions becomes persistent: punishments and moral messages interact to sustain cooperation. We investigate the mechanism through which moral suasion operates and find it to involve both expectation- and preference-shifting effects. These results suggest that the use of moral appeals can be an effective way of promoting cooperation.

The Evolutionary Robustness of Forgiveness and Cooperation

We study the evolutionary robustness of strategies in infinitely repeated prisoners' dilemma games in which players make mistakes with a small probability and are patient. The evolutionary process we consider is given by the replicator dynamics. We show that there are strategies with a uniformly large basin of attraction independently of the size of the population. Moreover, we show that those strategies forgive defections and, assuming that they are symmetric, they cooperate

Love, Hate and Murder: Commitment Devices in Violent Relationships

Many violent relationships are characterized by a high degree of cyclicality: women who are the victims of domestic violence often leave and return multiple times. To explain this we develop a model of time inconsistent preferences in the context of domestic violence. This time inconsistency generates a demand for commitment. We present supporting evidence that women in violent relationships display time inconsistent preferences by examining their demand for commitment devices. We find that "no-drop" policies -- which compel the prosecutor to continue with prosecution even if the victim expresses a desire to drop the charges -- result in an increase in reporting. No-drop policies also result in a decrease in the number of men murdered by intimates suggesting that some women in violent relationships move away from an extreme type of commitment device when a less costly one is offered.

The demand for bad policy when voters underappreciate equilibrium effects

Most of the political economy literature blames inefficient policies on institutions or politicians’ motives to supply bad policy, but voters may themselves be partially responsible by demanding bad policy. In this article, we posit that voters may systematically err when assessing potential changes in policy by underappreciating how new policies lead to new equilibrium behaviour. This biases voters towards policy changes that create direct benefits—welfare would rise if behaviour were held constant—even if those reforms ultimately reduce welfare because people adjust behaviour. Conversely, voters are biased against policies that impose direct costs even if they induce larger indirect benefits. Using a lab experiment, we find that a majority of subjects vote against policies that, while inflicting direct costs, would help them to overcome social dilemmas and thereby increase welfare. Subjects also support policies that, while producing direct benefits, create social dilemmas and ultimately hurt welfare. Both mistakes arise because subjects fail to fully anticipate the equilibrium effects of new policies. More precisely, we establish that subjects systematically underappreciate the extent to which policy changes will affect the behaviour of other people, and that these mistaken beliefs exert a causal effect on the demand for bad policy

Institutions and Behavior: Experimental Evidence on the Effects of Democracy

A novel experiment is used to show that the effect of a policy on the level of cooperation is greater when it is chosen democratically by the subjects than when it is exogenously imposed. In contrast to the previous literature, our experimental design allows us to control for selection effects (e.g. those who choose the policy may be affected differently by it). Our finding implies that democratic institutions may affect behavior directly in addition to having effects through the choice of policies. Our findings have implications for the generalizability of the results of randomized policy interventions.
