Opportunistic electoral fiscal policy cycle theory suggests that all subnational officials will raise fiscal spending during elections. Ideological partisan fiscal policy cycle theory suggests that only left‐leaning governments will raise election year fiscal spending, with right‐leaning parties choosing the reverse. This article assesses which of these competing logics applies to debt policy choices. Cross‐sectional time‐series analysis of yearly loan acquisition across Mexican municipalities—on statistically matched municipal subsamples to balance creditworthiness across left‐ and right‐leaning governments—shows that all parties engage in electoral policy cycles but not in the way originally thought. It also shows that different parties favored different types of loans, although not always according to partisan predictions. Both electoral and partisan logics thus shape debt policy decisions—in contrast to fiscal policy where these logics are mutually exclusive—because debt policy involves decisions on multiple dimensions, about the total and type of loans. 相似文献

China's Hybrid Adaptive Bureaucracy: The Case of the 863 Program for Science and Technology 下载免费PDF全文
Portrayals of China's bureaucratic behavior tend to emphasize either streamlined central control via top‐down directives emanating from a Leninist system, or a highly fragmented organization characterized by continuous horizontal bargaining. While both views have merit, they miss important but little‐recognized dynamics of Chinese bureaucratic behavior. Examination of the 30‐year evolution of a single organization, China's 863 Program, allows us a unique look inside the “black box” of decision making. First, we highlight a largely unrecognized mechanism of top‐down control: a signal‐response process that fosters substantial uncertainty for officials in the system. Second, our case highlights a circumstance in which reformers made radical moves—deployed as a “band‐aid” layer of rational‐instrumentalism—to meet a perceived external security threat. These moves demonstrate efforts to incorporate Weberian norms, and suggest sources of dynamism and learning in a “hybrid adaptive” bureaucracy. 相似文献

Responding to recent articles in Governance highlighting the need for improved measurement of bureaucratic characteristics, this article describes efforts to map Brazil's federal agencies on three dimensions—capacity, autonomy, and partisan dominance—derived from data on more than 326,000 civil servants. The article provides a “proof of concept” about the utility of agency‐level measures of these variables, demonstrating how they relate to an output common to all agencies: corruption. The article provides a first step in the direction of building a comparative research program that offers objective evaluation of bureaucracies within nation‐states, with the intent of better disentangling their impact on governance outcomes. 相似文献

The Economic Stimulus Act of 2008 dramatically but temporarily increased the mortgage loan amount eligible for insurance through the Federal Housing Administration (FHA). We use the implementation and expiration of these loan limits as a source of exogenous variation in the availability of FHA insurance to measure the impact on the overall mortgage market and conventional lending. We find that the introduction of higher loan limits increased the number of loan originations, but that the expiration of those loan limits roughly 6 years later did not significantly decrease affected loan originations. The substitution between loan products and small net impact on the overall mortgage market when the ESA loan limits expired may be explained by the return of a stronger conventional lending industry than existed during the housing crisis. 相似文献

After the 2008 global financial crisis, both the United States and the United Kingdom introduced austerity policies targeted at particular elements of their national budgets. The purpose of this article is to compare the nature of this retrenchment; the similarities and differences in how it was implemented; and its initial impacts on one of the expenditure areas particularly affected: affordable rental housing programs and housing support for low-income households. Using a wide range of data sources, we find evidence of political and fiscal policy analogies in the timing and forms of the initial policy choices and how these were modified in the face of economic and political pressures. There are considerable similarities both in the instruments used to reduce housing expenditures and in the early impacts on support mechanisms and recipients. However, we find different histories and trajectories of support between the two countries that suggest that the longer term differences in outcomes may be more important. 相似文献

A Concurrent Analysis of Three Institutions that Transform Health Technology‐Based Ventures: Economic Policy,Capital Investment,and Market Approval 下载免费PDF全文
Drawing on institutional theory, this article articulates qualitative insights from a program of research on Canadian health technology‐based ventures to examine the rules that characterize economic policy, capital investment, and regulatory approval as well as the way these institutions enable and constrain the development of ventures at an early stage. Our findings clarify how economic policy integrates these ventures into the entrepreneurial domain, how capital investment configures them for economic value extraction, and how regulatory approval fully releases their market value. These findings help to revisit current policy modernization initiatives by calling attention to the convergence among the three institutions. Rather than operating solely as a source of constraints, these institutions provide a highly integrated market‐oriented space for health technology‐based entrepreneurial activities to unfold. 相似文献

Many core graduate-level seminars claim to expose students to their discipline’s “canon.” The contents of this canon, however, can and do differ across departments and instructors. This project employs a survey of core American politics PhD seminar syllabi at highly ranked universities to construct a systematic account of the American politics canon. Our results offer valuable insights into the topics and literature that political scientists consider important and on which future scholars base their work. Our article breaks down the literature into a comprehensive list of topics and subtopics, which allows us to identify both an overall field canon and one for each topic, to assess whether some topics receive more attention than others, and to identify which topics are most clearly defined. We explore the extent to which diverse perspectives and methods are (or are not) taught to young scholars, and, although we identify sets of frequently assigned readings and authors within each topic, we also find considerable variation between seminars. 相似文献
