Much of the public budgeting literature focuses on the institutional rules of budgeting and how those rules affect process and outcomes. This study focuses on a particularly rudimentary rule of budgeting: the length of the budget period. State budgets are dictated (constitutionally or statutorily) to recur over one-or two-year intervals. Statistical analysis of the determinants of state budget periodicity shows that the more states spend, ceteris paribus, the more likely they are to budget annually. I hypothesize that budget periodicity has the opposite effect on spending: Biennial budget states spend more, ceteris paribus, than annual budget states spend. Ordinary least squares analysis does not support the hypothesis, but with instrumental variable methods, biennial budgeting exhibits a positive and statistically significant effect on state spending.  相似文献

The median voter hypothesis (MVH) represents a much-used as well as much-criticized tool in the hands of public finance economists. To evaluate the MVH, this paper applies the Cox specification test using data from general purpose municipal governments. The Cox test allows for possible simultaneous rejection of the MVH and all tested models, thus providing stricter criteria than applied to date in empirical MVH analyses. The test results reveal that the MVH is appropriate for explaining the aggregate behavior of municipal governments, but not specific services. Further, the single service and single tax base assumptions are not critical to the empirical MVH performance.  相似文献

This article analyzes the impact of the Gramm-Rudman-Hollings (GRH) Act on federal budgetary and fiscal outcomes. Rather than portraying it as a two-on federal budgetary and fiscal outcomes. Rather than portraying it as a two-party game between Congress and the president, each with monolithic policy preferences, we view GRH as a multiparty negotiation game among advocates of different programs and agencies. In this game, agencies subject to sequestration and their congressional advocates have an incentive to reach a budget accord, while those exempt from sequestration do not. Consistent with this argument, we find that GRH has restrained outlays for nonexempt programs and that exempt programs have, if anything, experienced more rapid growth. Overall, GRH is estimated to have restrained outlays by $59 billion by fiscal 1989, and to have restrained outlays more effectively after the 1987 modifications in the Act. The Gramm-Rudman-Hollings Act signals another phase in the decade-long struggle between the White House and Congress over public spending priorities. Our final counterfactual analysis suggests that GRH partially returned federal fiscal and budgetary relationships and priorities to those that prevailed before Reagan.  相似文献

Central to this article is the question, “Are tax expenditure reports used?” State legislators serving on tax committees in ten states were surveyed regarding their use and their perceptions of others' use of tax expenditure report information. Responses indicate (1) strong acceptance and broad use of report information; (2) purposes and policy stages of use characteristic of technical information use; and (3) use focused predominantly on resource acquisition (revenue) policy rather than resource allocation (budget) policy. Thus it appears that tax expenditure reporting does not operate to secure budgetary control over tax expenditures, and consequently tax expenditures continue largely to escape budget scrutiny.  相似文献

A pervasive theme of the congressional politics literature is that the committee system is fundamental in determining the policy status quo. Such an assertion hinges crucially upon committees controlling their jurisdictions; congressional delegation is undermined if a committee can assert authority over any issue domain at any time. Yet, representatives may possess an incentive to support a policy proposal that would change the status quo, even if it entails disregarding procedures. Indeed, standard conceptualizations of how members of Congress make their voting choices assume that only the benefits and costs associated with a policy matter, and they do not consider institutional factors such as whether a bill emerged from the correct committee.This analysis examines whether representatives will sacrifice policy interests to preserve institutional features of the legislature. The effort in 1987 to curb smoking on airplanes — which became embroiled in a difficult-to-resolve jurisdictional dispute — serves as a vehicle to analyze how sensitive members are to such features. The results demonstrate that a sizable number put aside their [generally moderate] policy preferences and voted against limits on smoking for institutional reasons. These findings have important implications both for specifying the determinants of policy change and for understanding institutional stability.  相似文献

We conducted a short-term longitudinal study examining the structure of coping behavior and the relationship between coping style and depression during adolescence. The sample consisted of 603 adolescents in Grades 6–11 who were surveyed in the fall of 1989 and again in the fall of 1990. A two-dimensional model of coping was found using confirmatory factor analysis with the factors being approach and avoidant coping. Four cross-sectional and seven longitudinal coping groups were formed to explore group differences in depression. Approach copers reported the fewest symptoms of depression, while avoidant copers reported the most. Subjects who changed over time from approach to avoidant coping evidenced a significant increase in depressive symptoms, whereas subjects who switched from avoidant to approach coping displayed a significant decrease in depression over a one-year period. These findings imply that adolescents who are able to elicit social support, engage in problem solving, and cognitively restructure events within a positive light are more likely to successfully negotiate the challenges of adolescence.This research was supported by a grant from the William T.
