Voter participation rates vary widely across the 50 states and the District of Columbia. This empirical study seeks, within the context of a broadened version of the “rational voter model,” to identify determinants of this geographic variation. Using the 2014 mid-term general election, it was found that the voter participation rate across states and the District of Columbia was positively related to whether there is a close governor’s race or a close U.S. Senate race, the female labor force participation rate, the percent of the population aged 65 and over, the number of referenda on the ballot, and the degree of voting-by-mail usage. In addition, it was found that voter turnout was negatively related to the percentages of the population that are either Hispanic or Afro-American.  相似文献

After the outbreak of the global financial crisis, some governments in the EU experienced serious fiscal problems, while others were less affected. This paper seeks to shed light on the divergent fiscal performance in the EU countries before and after the outbreak of the crisis. Fiscal reaction functions of the primary balance are estimated for different groups of EU countries using quarterly data for the pre-crisis period 2001–2008 and for the crisis period 2009–2014. The pre-crisis estimations reveal some differences in persistence and cyclical reaction between different groups of countries, but in most cases little feedback from the debt stock to the primary balance. The fiscal reaction functions of the countries that eventually developed fiscal problems do not stand out. The estimations on data from the crisis period show largely unchanged persistence and counter-cyclicality but much more feedback from the debt stock, and this applies both to the crisis countries and those less affected. In spite of large deficits and accumulation of debt, the underlying fiscal reaction has become more prudent after the outbreak of the European debt crisis.  相似文献

It is well documented that individuals do not spend the Supplemental Nutrition Assistance Program (SNAP) benefits smoothly over the month after receipt. Rather, recipients spend a disproportionate share of benefits at the beginning of the benefit month. This has costs for recipients and stores. There is also evidence that other income streams, such as Social Security and paychecks, are not spent smoothly. The presence of these other income streams may bias estimates of the effects of this SNAP cycle on consumption for working SNAP beneficiaries and those who receive other government benefits. We use data from United States Department of Agriculture's National Household Food Acquisition and Purchase Survey to explore how the SNAP cycle is affected by accounting for these other income streams. We find suggestive evidence that the cycle is more pronounced for workers who are paid on a weekly or monthly basis, but little evidence that cycles in other income streams mitigate or exacerbate the SNAP cycle.  相似文献

This article continues the discussion raised in the pages of the journal on the methodological problems of justifying economic policy [1]. Problems of measuring the inflationary component of economic growth and in product competitiveness in the internal market and external markets are considered. A procedure to measure economic growth, taking into account the balance of interests of the current and future generations, is proposed.  相似文献

A structural multivariate long memory model of the US gasoline market is employed to disentangle structural shocks and to estimate the own-price elasticity of gasoline demand. Our main empirical findings are: (1) there is strong evidence of nonstationarity and mean reversion in the real price of gasoline and in gasoline consumption; (2) accounting for the degree of persistence present in the data is essential to assess the responses of these two variables to structural shocks; (3) the contributions of the different supply and demand shocks to fluctuations in the gasoline market vary across frequency ranges; and (4) long memory makes available an interesting range of convergent possibilities for gasoline demand elasticities. Our estimates suggest that after a change in prices, consumers undertake a few measures to reduce consumption in the short- and medium-run but are reluctant to implement major changes in their consumption habits.  相似文献

In Turkey, the empirical results on the link between financial development and economic growth are mixed. The existing studies do not take into account the fact that Turkey has experienced endemic political and economic instabilities over extended periods. This study aims to analyse the role of macroeconomic instability and public borrowing on the finance–growth nexus in Turkey by using time series econometric techniques over the 1980–2010 period. In doing so, we attempt to extend the existing literature by taking into account the role of macroeconomic instability as well as public borrowing. Our results reveal that there are additional – albeit indirect – channels between finance and growth via the effects of macro instability and public borrowing on financial development and economic growth. After taking into account the effects of overall instability and public borrowing, we found that growth–financial development relationship is bidirectional and permanent. In other words, in Turkish case, economic growth and financial development are jointly determined. Thus, our results shed some light on the ambiguity of the evidence on the link between financial development and economic growth for Turkey.  相似文献

In recent decades, knowledge spillovers have taken the helm as the driving force of growth in cities. The ease of communicating ideas and the sheer density of large urban areas have made this a plausible explanation for continued growth of employment and population in cities. However, there is little consensus on the nature of the optimal conditions for stimulating knowledge spillovers. This paper identifies these optimal conditions by exploring the relative importance of industry specialization, diversity and competition across all industries and all metropolitan areas from 1970 to 2011 in the U.S. Long-term employment growth in cities is found to be driven by industry diversity combined with a high level of competition. This combination fosters the greatest amount of cross-industry fertilization of ideas and knowledge spillovers.  相似文献

This paper investigates the effects of trade finance shocks on real exports by using novel data on two bank-intermediated instruments of trade finance in Korea: foreign trade loans extended by commercial banks and documentary bills purchased by them. Using a vector autoregression (VAR) model, the results show that a negative shock to both instruments adversely affects exports, particularly the exports of small and medium-sized enterprises (SMEs). The trade financing condition explains as much as 10–14 % of the variation in exports, which is comparable to the estimates in previous studies. Noteworthy is that the effects of trade finance on SME exports vary upon whether it is pre- or post-shipment financing.  相似文献
