Most studies of policy feedback have focused on processes of self‐reinforcement through which programs bolster their own bases of political support and endure or expand over time. This article develops a theoretical framework for identifying feedback mechanisms through which policies can become self‐undermining over time, increasing the likelihood of a major change in policy orientation. We conceptualize and illustrate three types of self‐undermining feedback mechanisms that we expect to operate in democratic politics: the emergence of unanticipated losses for mobilized social interests, interactions between strategic elites and loss‐averse voters, and expansions of the menu of policy alternatives. We also advance hypotheses about the conditions under which each mechanism is likeliest to unfold. In illuminating endogenous sources of policy change, the analysis builds on efforts by both historically oriented and rationalist scholars to understand how institutions change and seeks to expand political scientists’ theoretical toolkit for explaining policy development over time.  相似文献

Police stress has received intermittent coverage in the literature for the last decade, and it remains a constant source of discussion today. One of the reoccurring problems with stress studies is that they attempt to examine the phenomenon globally. This almost always leads to generalized findings which may be representative of the overall problem, but certainly fail to adequately micro-examine the intracies of the issue. This article examines perceptions of stress relative to the demographic and assignment characteristics of police officers in a medium sized city. It identifies three specific patterns and suggests directions for additional research.  相似文献

The deterioration of the supply of public infrastructure throughoutthe United States has been found to be accelerating. The reasonmost often cited for the increasing rates of deterioration isthe lack of available funding, or fiscal stress, present inmany local governments. A popular short-term solution to fiscalstress is to defer infrastructure repairs and/or replacementprograms. This is particularly true in rural areas where a decliningagricultural base and redirected federal policy have placedsignificant downward pressure on revenues. The search for along-term solution has renewed the debate about the optimalsize of local governments. The research reported here examinesthe issue of size efficiency in the production of low-volumerural roads in the Midwest. At issue is the ability of Midwesttownships to realize size economies. Overall, size inefficiencieswere identified which suggests that cost savings may be realizedfrom the reorganization of the production of low-volume roadservices.  相似文献

Mental health professionals (N=198) read a vignette describing malpractice case and were asked to imagine themselves in the role of defendant. Using a between-subjects design, each subject was offered two possible trial procedures for resolving the case, the standard adversary procedure (ADVERS) and one of five possible hybrid procedures. Using scales that juxtaposed these two procedures, subjects provided judgments on 12 procedural justice dimensions. A series of regression analyses examined the most important determinants of PREFERENCE judgments, FAIRNESS ratings, and ratings of imagined COMPLIANCE with trial outcomes. PREFERENCE raings were significantly influenced by perceived FAIRNESS of the procedures and by OUTCOME CONTROL. Perceived ACCURACY of the available trial procedures contributed most of the unique variance explained for dependent measures of FAIRNESS AND COMPLIANCE. Results are discussed in terms of the procedural justice attributes of alternatives to the standard adversary process for resolving medical malpractice cases.Division 41 Presidential Address presented at the Annual Convention of the American Psychological Association in Toronto, August, 1993.
