Right-wing politicians sometimes can implement policies that left-wing politicians cannot, and vice versa. Contemporary wisdom has it that only Nixon could have gone to China. We develop a model to explain this phenomenon. A policy issue could depend on information, on which every one could potentially agree on policy, or on values, on which agreement is impossible. Politicians, who value both reelection and policy outcomes, realize the nature of the issue, whereas voters do not. Only a right-wing president can credibly signal the desirability of a left-wing course of action. The Nixon paradox can hold then if citizens vote retrospectively on the issue.  相似文献

Understanding differential policy costs across constituencies, and how they link to legislators' policy preferences, can facilitate policy changes that solve pressing problems. We examine the role of policy costs on constituents by studying legislator support for taxing gasoline. Analysis of survey responses from US state legislators, as well as of their voting records, shows that legislators whose constituents would be most affected by an increased gas tax—those whose constituents have longer commutes—are more likely to oppose higher gas taxes. Separately estimating the impact of time spent driving to work versus using public transit shows that the effect of commute times comes from those who have long drives, not from those who ride public transit, highlighting how the policy costs to constituents is a major driver in legislators' considerations. We finish the article by discussing the implications of our findings for combating climate change and for understanding policy feedbacks.  相似文献

Research summary

This study uses a combination of tract-level and street network-level analyses to examine: (1) the overall association between federally licensed firearm dealers (FFLs) and homicides, (2) the relationship between dealers with serious violations (such as selling to prohibited buyers or failing to record sales) and homicide, and (3) whether the dealer–homicide association is moderated by community disadvantage. Results replicate and confirm a relationship between dealers and homicides in disadvantaged neighborhoods. Importantly, however, we also find that proximity to noncompliant dealers specifically elevates the risk of lethal violence.

Policy implications

We detail how a coordinated effort between federal, state, and local agencies to regulate firearm dealers and ensure that legal compliance can be instrumental in reducing gun violence. There is a clear need for increased oversight of gun dealers and more robust policies that hold negligent dealers accountable, including the necessary funding and regulatory manpower to enable regular auditing and support consistent follow-up for noncompliant dealers. A comprehensive policy framework that supports supply-side gun violence reduction should include additions to state-level laws that require record keeping, videotaping and store security, and regular inspection for firearm dealers.  相似文献

We argue that politicians systematically discount the opinions of constituents with whom they disagree and that this “disagreement discounting” is a contributing factor to ideological incongruence. A pair of survey experiments where state and local politicians are the subjects of interest show that public officials rationalize this behavior by assuming that constituents with opposing views are less informed about the issue. This finding applies both to well‐established issues that divide the parties as well as to nonpartisan ones. Further, it cannot be explained by politicians’ desires to favor the opinions of either copartisans or likely voters. A third survey experiment using a sample of voters shows that the bias is exacerbated by an activity central to representative governance—taking and explaining one's policy positions. This suggests that the job of being a representative exacerbates this bias.  相似文献

Studies of clientelism typically assume that political machines distribute rewards to persuade or mobilize the existing electorate. We argue that rewards not only influence actions of the electorate, but can also shape its composition. Across the world, machines employ “voter buying” to import outsiders into their districts. Voter buying demonstrates how clientelism can underpin electoral fraud, and it offers an explanation of why machines deliver rewards when they cannot monitor vote choices. Our analyses suggest that voter buying dramatically influences municipal elections in Brazil. A regression discontinuity design suggests that voter audits—which undermined voter buying—decreased the electorate by 12 percentage points and reduced the likelihood of mayoral reelection by 18 percentage points. Consistent with voter buying, these effects are significantly greater in municipalities with large voter inflows, and where neighboring municipalities had large voter outflows. Findings are robust to an alternative research design using a different data set.  相似文献

In the 1975 referendum England provided the strongest support for European integration, with a much smaller margin for membership in Scotland and Northern Ireland. By 2015 the rank order of ‘national’ attitudes to European integration had reversed. Now, England is the UK's most eurosceptic nation and may vote ‘Leave’, while Scotland seems set to generate a clear margin for ‘Remain’. The UK as a whole is a Brexit marginal. To understand the campaign, we need to make sense of the dynamics of public attitudes in each nation. We take an ‘archaeological’ approach to a limited evidence‐base, to trace the development of attitudes to Europe in England since 1975. We find evidence of a link between English nationalism and euroscepticism. Whatever the result in 2016, contrasting outcomes in England and Scotland will exacerbate tensions in the UK's territorial constitution and could lead to the break‐up of Britain.  相似文献

On 2 November 2014 George Osborne stood in the impressive great council chamber of Manchester town hall and, flanked by the ten leaders of Greater Manchester's local authorities, announced a devolution deal for the city‐region. Greater Manchester would receive a significant package of powers over transport, housing, planning, skills, business support and welfare in exchange for creating new governance structures, including a directly elected mayor for the city‐region. This article explores the background to the Devo Manc deal, arguing that it is the product of both a long history of local government collaboration in Greater Manchester and George Osborne's desire for a sweeping restructure of English governance. It traces how the key decisions were taken quickly and by a small number of key officials. The article also identifies some flaws in Devo Manc and considers whether it is an appropriate model for other city‐regions in the UK.  相似文献
