We study business cycle fluctuations in heterogeneous agent general equilibrium models featuring intensive and extensive margins of labor supply. A nonlinear mapping from time devoted to work to labor services generates operative extensive and intensive margins. Our model captures the salient features of the empirical distribution of hours worked, including how individuals transit within this distribution. We study how various specifications influence labor supply responses to aggregate technology shocks and find that abstracting from intensive margin adjustment can have large effects on the volatility of aggregate hours even if fluctuations along the intensive margin are small.  相似文献

The recent process of political and economic transition in eastern European countries has not only contributed to the decentralisation of political structure but also significantly enhanced the fiscal autonomy of municipalities in these countries. In this context many similar types of public activities have recently been assigned to local governments, and some taxes were also declared to be local taxes. To be sure, this type of fiscal decentralisation has caused some additional problems, particularly for safeguarding the quality of publicly provided goods and services and for co-ordinating intergovernmental fiscal transfers between the central and local governments. For instance, some criticise that many small-sized municipalities in the transition economies have suffered from financial bottlenecks and have not been able to receive sufficient financial support from the central government. However, such a fiscal devolution trend appears to continue. This study primarily deals with issues surrounding the impact of national fiscal policy and the regulatory framework on local governments' expenditure behaviour and their ability to mobilise necessary revenues under the particular consideration of the institutional and administrative co-operation with the central government and of the less well-developed financial market in Poland, the Slovak Republic, the Czech Republic and Hungary.  相似文献

目前国内研究尚缺乏一套科学的、系统的、有效的对地铁运营的评价体系.本文以成都地铁为研究对象,采用问卷调研法,将16个初级指标做成问卷让受访者进行打分,之后将数据导入SPSS软件,分析其效度与信度,剔除信度较低的指标,最终获得3个一级指标和15个重要的二级评价指标,并以此构建出一套对地铁运营绩效的评价指标.最后通过对受访者问卷的打分情况,分析出乘客看重哪些因子,并以此向相关部门提出建议.  相似文献

For politicians, appointments are an instrument of policy influence.By installing their representatives in an institution, politicianscan count on policy influence for the duration of their appointees'terms. Given the stakes, the occasional controversy regardingnominees is understandable. On the whole, however, nominationsare not controversial; in fact, Senate confirmation votes areoften unanimous. Nevertheless, the Senate can have substantialinfluence in the appointment process. Using a formal model,this article examines how the president and Senate strategicallybargain with one another within the confines of the FederalReserve appointment process to influence monetary policy. Witha new way to estimate monetary policy preferences, this articleshows empirically that policy influence occurs via appointments.  相似文献

Stiroh and Rumble (2006) and Yeager et al. (2007) have argued that extension of banks into nonbanking activities produces no diversification benefits for financial services holding companies (FSHCs) eligible to consolidate banking and insurance products. We investigate the effect of aggregate nonbank activities, as well as two main areas of insurance business, namely agency and underwriting enterprise, on the risk-adjusted performance of FSHCs. Our sample includes a quarterly panel data of FSHCs over the period 2003–2011. We find that the effect of FSHCs’ entry into agency insurance activities on their risk-adjusted returns is dependent on their size; it is positive for FSHCs in the top quartile of our sample (assets greater than $4.495 billions), but negative for smaller and mid-size FSHCs. The effect of underwriting insurance activities on risk-adjusted returns is generally negative or statistically insignificant, except for some of the largest-size firms.  相似文献

Scholars believe that higher social expenditures are usually linked with higher government debts, whereas higher debts reduce social expenditures. However, it is reasonable to speculate that higher government debt may contribute to higher social spending, while fiscal deficits occur during a recession, which commonly creates greater demand for social expenditure. For a deeper investigation, this paper revisits the dynamic relationship between social spending and public debts in the time-frequency domain, using the novel wavelet-coherency analysis as well as the phase-difference technique to derive the co-moved and causal relationships between social spending and public debts in 13 OECD countries. The evidence identifies a dynamic relationship between variables. While higher social expenditures increase government debts, the shocks from government debts to social expenditures are conversely uncertain. We discover that higher government debt does reduce social expenditures, but it may be linked to higher social spending. The robustness of partial coherency and phase-difference discovers the role of a political party in the decision over social welfare programmes in the sample countries.  相似文献
