This paper traces the history of modern terrorism from the end of the Second World War to the beginning of the twenty-first century. It divides that history into three stylized waves: terrorism in the service of national liberation and ethnic separatism, left-wing terrorism, and Islamist terrorism. Adopting a constitutional political economy perspective, the paper argues that terrorism is rooted in the artificial nation-states created during the interwar period and suggests solutions grounded in liberal federalist constitutions and, perhaps, new political maps for the Middle East, Central Asia and other contemporary terrorist homelands.  相似文献

Public management scholars often claim that agency competition provides an effective institutional check on monopoly authority, and hence, leads to improvement of administrative performance in public sector agencies. This logic was central for creating the Congressional Budget Office (CBO) in 1975 to challenge the policy information provided by the Office of Management and Budget (OMB). We challenge this conventional wisdom by demonstrating that CBO has failed to enhance the quality of U.S. fiscal policy analysis on its own terms; nor has it spurred improvements in OMB's performance. Our empirical results indicate that the quality of OMB's fiscal projections has often deteriorated since the establishment of CBO as a rival bureau. We also show that both public and private information is being shared by these agencies to produce a similar caliber of task outputs. The broader implications of our study indicate that although politicians face incentives to employ agency competition in governmental settings, this type of bureaucratic strategy does not necessarily enhance the quality of administrative performance. © 2006 by the Association for Public Policy Analysis and Management  相似文献

For a single-winner multi-candidate election, it is broadly accepted that the Condorcet candidate (if one exists) should win. Voting systems do not always elect the Condorcet winner. Public opinion polls are not generally designed to try to identify a Condorcet candidate. They could easily be constructed to do so, however. The resulting process may be called Condorcet polling, for which various designs are presented herein. Information from Condorcet polling may enable some voters, under a plurality or runoff system, to bring about an outcome they prefer by voting strategically for the Condorcet candidate when they would not otherwise do so.  相似文献

Despite ample evidence of preelection volatility in vote intentions in new democracies, scholars of comparative politics remain skeptical that campaigns affect election outcomes. Research on the United States provides a theoretical rationale for campaign effects, but shows little of it in practice in presidential elections because candidates’ media investments are about equal and voters’ accumulated political knowledge and partisan attachments make them resistant to persuasive messages. I vary these parameters by examining a new democracy where voters’ weaker partisan attachments and lower levels of political information magnify the effects of candidates’ asymmetric media investments to create large persuasion effects. The findings have implications for the generalizability of campaign effects theory to new democracies, the development of mass partisanship, candidate advertising strategies, and the specific outcome of Mexico's hotly contested 2006 presidential election. Data come primarily from the Mexico 2006 Panel Study.  相似文献

Social scientists widely regard the random‐assignment experiment as the gold standard for making causal inferences about the world. We argue that it can be improved. For situations in which self‐selection and heterogeneity of treatment effects exist, an alternative experimental design that retains random assignment to treatment or control and supplements it with some self‐selection of condition offers a clear advantage. It reveals the average treatment effect while also allowing estimation of the distinct effects of the treatment on those apt and inapt to experience the treatment outside the experimental context.  相似文献

We develop a model of intraparty candidate selection under partisan electoral competition and voter uncertainty. Candidates for office belong to parties, which are factions of ideologically similar candidates. Each party’s candidate for a general election can be selected either by a “centralized” mechanism that effectively randomizes over possible candidates or by voters in a primary election. The electorate cares about ideology and valence, and both primary and general elections may reveal candidate valences. Our main theoretical result is that while primaries raise the expected quality of a party’s candidates, they may hurt the ex ante preferred party in a competitive electorate by increasing the chances of revealing the opposing party’s candidates as superior. Thus, primaries are adopted in relatively extreme districts where a clear favorite party exists. An empirical analysis of the adoption of direct primaries and the competitiveness of primary elections across U.S. states supports these predictions.  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
