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

The hostile media effect (HME) has generally been tested in terms of in-groups and out-groups, with a “neutral” story in between. This ignores the nature of many social groups as comprising subgroups, often but not always sharing feelings of connectedness and purpose. In cases when bounded subgroups are at odds with one another, HME provides little guidance. A contested partisan primary provides such a case. This study takes identity centrality, candidate favorability, and perceived social network homogeneity as measures of partisanship and involvement, hypothesizing relationships between each and perceived bias against one’s candidate and party. Findings show that markers of candidate-focused social identity predict greater perceived bias against one’s candidate during the 2016 primary season, while party-focused identity fails to predict perceived bias against one’s party. This suggests that candidate support identity overrides plain partisanship during primaries, supporting concern that a heated primary might damage general election party unity. Subsequent postconvention findings suggest that the salience of candidate-focused identity fades, while homogeneity of one’s network regarding party support helps to make perceived hostility toward one’s party identity more salient. However, as campaigns become more candidate-centered, the contestation between nested candidate and party identities may grow fiercer.  相似文献

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

Within the teaching of political theory, an assumption is emerging that Reacting to the Past simulations are an effective tool because they encourage greater student engagement with ideas and history. While previous studies have assessed the advantages of simulations in other political science subfields or offered anecdotal evidence of their effectiveness in political theory courses, less attention has been paid to the empirical assessment of simulations in political theory. This study uses data — in the form of presimulation and postsimulation surveys, as well as focus groups — collected from two political theory courses in order to gauge levels of student engagement inside and outside of the classroom. We ask if students’ levels of engagement increase during the simulation in their political theory courses. We also explore the mechanisms involved in driving higher levels of student engagement during the simulation. We conclude by arguing that it is the liminal nature of the Reacting to the Past simulations that most likely explains increased levels of student engagement.  相似文献

In federal systems, both state governments and firms have incentives to strategically locate polluting facilities where the environmental and health consequences will be borne as much as possible by residents of other jurisdictions. We analyze air polluter location in the United States using a spatial point pattern model, which models where events occur in latitude and longitude. Our analyses indicate that major air polluters are significantly more likely to be located near a state's downwind border than a control group of other industrial facilities, results that are robust to a wide variety of model specifications and measurement strategies. This effect is particularly pronounced for facilities with toxic air emissions. The observed pattern of polluter location varies systematically across states and time in ways that suggest it is responsive to public policy at both the national and state levels.  相似文献

We develop a model of leadership in which an informed leader has some degree of coercive influence over her followers (agents). Agents benefit from coordination but face two distinct challenges: dispersed information and heterogeneous preferences. The leader's coercive power facilitates coordination by weakening the effect presented by both of these challenges through “binding” agents to a strategically chosen policy. The leader's policy choice becomes more informative to the agents about the leader's privately held information as her coercive capacity increases. By adjusting her policy choice in response to available private and public information, the coercive leader achieves her preferred average of agents' actions, and in so doing, neutralizes the possibly deleterious coordinating influence of public information. We develop implications of our analysis for understanding autocratic leadership in different political and organizational contexts.  相似文献
