A positive, statistical and economic significant relation between growth, income level and the Economic Freedom of the World (EFW) index has been amply documented. Most analyses, however, use OLS methods which, in the presence of endogenous variables do not establish causality and produce biased and inconsistent estimates. This paper uncovers the exogenous component of EFW using IV methods and finds a robust channel from economic freedom to prosperity. The findings, including instrument validity tests, support the importance of policies and institutions for development and warrants policy advice aimed at increasing economic freedom to foster prosperity. 相似文献

The riskiness of state employee pension plan portfolios varies across states. We investigate whether this variation is related to how public employees and taxpayers share actuarial surpluses of pension accounts. We focus on two determinants of a plan’s asset mix: the relative influence of public employees to taxpayers; and whether a surplus-sharing contract is specified. Our theoretical model demonstrates that the effect of public employee influence on the asset mix is ambiguous. Our empirical results corroborate this complex theoretical result. In our theoretical and empirical analyses, if a surplus sharing rule is specified, plans adopt a more aggressive investment allocation. 相似文献

Individual citizens are the largest source of contributions for congressional candidates in the United States. This paper investigates if and how fundraising from this source is related to the ideological positions of candidates. Specifically, we ask whether the amount of contributions depends on: (1) the extremity of candidate ideology; and (2) the level of candidate divergence in the same race. These results have important implications for candidate positioning strategies, as well as for evaluating the effects of recent campaign finance reforms. 相似文献

In this paper, we examine whether the impact of negative advertising on citizens’ evaluations of candidates depends on the
gender of the candidates. Given common gender stereotypes, we expect negative campaigning aimed at women candidates will affect
citizens differently than negative campaigning against male candidates. The results of our study, derived from a survey experiment
conducted on a nationwide sample of more than 700 citizens, demonstrate that negative commercials are less effective at depressing
evaluations of woman candidates, compared to male candidates. The findings are consistent and strong, across a range of forces
that people use to assess competing candidates (i.e., affect and trait evaluations, people’s beliefs about issues, anticipated
vote choice). The tight control of the experimental design, including randomization of respondents into different conditions
that vary in only one way, demonstrates that the gender of the candidate influences people’s reactions to different types
of negative commercials.

From 9/11 in the U.S. to train, subway, and airport bombings elsewhere, individuals frequently must make political decisions
in the shadow of terrorist attacks. To date, few studies have examined how times of terror threat influence voters’ decision-making
processes. Using data generated from three experiments we show that, in times of terrorist threat (compared to good times),
individuals weight leadership more heavily in the voting booth. Our results also shed light on how much weight is given to
other determinants of the vote (issues and partisanship) across these two conditions. 相似文献

Does public policy respond to public opinion? Previous research suggests dynamic representation occurs in the aggregate. Yet, most of the evidence for policy response is limited to the policy intentions of elected officials on issues related to more or less government spending. We examine policy response to an alternative dimension of public mood, public preferences for more or less punitive criminal justice policies, using multiple indicators of policy from various stages of the policy-making process. Criminal justice policy should be responsive to public preferences given the public’s concern about crime and the negative social construction of criminals. Thus, there is an electoral incentive for public officials to respond to public preferences along this alternative dimension of public sentiment regarding criminal justice policy. We estimate a DYMIMIC model of federal criminal justice policy as a function of the multiple dimensions of public policy mood using Kalman filtering. The results indicate that criminal justice policy responds to the second, not the first, dimension of public mood. We find evidence that policy-makers at multiple stages of the policy process are able to differentiate among multiple signals from the public and respond appropriately. The results present a more sophisticated portrait of democratic responsiveness. 相似文献
