When a product's product provision entails fixed costs, it will be made available only if a sufficient number of people want it. Some products are produced and consumed locally, so that provision requires not only a large group favoring the product but a large number nearby. Just as local governments provide public goods appealing to individuals sharing the median voter's preferences for local public goods, product markets may provide an analogous benefit to individuals sharing living communities whose consumers tend to share his preferences in private goods. Using zip code level data on chain restaurants and restaurants overall, this paper documents how the mix of locally available restaurants responds to the local mix of consumers, with three findings. First, based on survey data on chain restaurant patronage, restaurant preferences differ substantially by race and education. Second, there is a strong relationship between restaurants and population at the zip code level, suggesting that restaurants' geographic markets are small. Finally, the mix of locally available chain restaurants is sensitive to the zip code demographic mix by race and by education. Hence, differentiated product markets provide a benefit—proximity to preferred restaurants—to persons in geographic markets whose customers tend to share their preferences.  相似文献

Most election forecasting research to date has been conducted in the context of single-round elections. However, more than 40 countries in the world employ a two-stage process, where actual voting data are available between the first and the second rounds to help politicians understand their position in relation to each other and to voter preferences and to help them predict the final outcome of the election. In this study we take advantage of the theoretical foundation on voter behavior from the political science literature and the recent methodological advances in choice modeling to develop a Nested Logit Factor Model of voter choice which we use to predict the final outcome of two stage elections and gain insights about the underlying political landscape. We apply the proposed model to data from the first stage and predict the final outcome of two stage elections based on the inferences made from the first stage results. We demonstrate how our proposed model can help politicians understand their competitive position immediately after the first round of actual voting and test its predictive accuracy in the run-off election across 11 different state governorship elections.  相似文献

We examine 20 partisan judicial elections over an 8-year period to determine whether judge specific information shows in election results. We find demand for judicial sanctions looks much like other voting processes. Among voters, Democratic incumbent judges, who tend to be lenient, are rewarded for being harsh, while Republican incumbent judges, who generally are harsh, are rewarded for being lenient. Voters are not found to be a random sample of the population, and we find that straight ticket votes obscure information from selective voters. This paper benefitted from comments received by participants at the Public Choice Meetings, and from useful comments from Aimee Chin, Janet Kohlhase, an anonymous referee and the editor.  相似文献

Many papers have tested the prediction of the rational voter model that, ceteris paribus, turnout will be low when potential voters expect the winner's plurality to be large. The appropriate null hypothesis, however, is unclear. We show that statistical models of voting in which each voter's decision of whether to vote does not vary with the expected plurality can nonetheless generate data which lead to both positive and negative correlations between turnout and plurality.  相似文献

The purpose of this paper is twofold: first, to provide a closed form expression for the median of the Poisson distribution and, second, to improve the known estimates of the difference between the median and the mean of the Poisson distribution. We use elementary techniques based on the monotonicity of certain sequences involving tail probabilities of the Poisson distribution and the Central Limit TheoremReceived November 2002  相似文献

There is a growing literature suggesting that the result for each constituency at British general elections can be predicted using ‘citizen forecasts’ obtained through voter surveys. This may be true for the majority of constituencies where the result at previous contests was a substantial majority for one party’s candidates: few ‘safe seats’ change hands. But is it true in the marginal constituencies, where elections are won and lost? Analysis of such ‘citizen forecast’ data for the Labour-Conservative marginal constituencies in 2017 indicates not. Although respondents were aware of the seats’ relative marginality and of general trends in party support during the campaign, they could not separate out those that were eventually lost by each party from those that were won again, even in seats where the elected party won comfortably.

This study investigates the direct and indirect effects of financial participation (FP) and participation in decision-making (PDM) on employee job attitudes. The central premise is that both financial participation and participation in decision-making have effects on job attitudes, such as integration, involvement and commitment, perceived pay equity, performance-reward contingencies, satisfaction and motivation. After reviewing the theoretical and empirical literature and testing two theoretical frameworks, developed by Long (1978a) and Florkowski (1989), a new model was constructed to consider a combined effects of both FP and PDM, herein referred to as employee participation (EP). The underpinning of the model is based on the assumption that both (a) the combination of financial participation and participation in decision-making (‘employee participation’), and (b) participation in decision-making produce favourable effects on employee job attitudes. The test of the new model showed that employee participation does not produce more favourable effects on employee job attitudes, than does participation in decision-making on its own. The data were gathered from a questionnaire study administered in a large British retail organization that operates two types of ownership schemes – profit-sharing and SAYE schemes.  相似文献

Measuring housing affordability: Looking beyond the median   总被引:7,自引:0,他引:7  
We draw a distinction between the concepts of purchase affordability (whether a household is able to borrow enough funds to purchase a house) and repayment affordability (the burden imposed on a household of repaying the mortgage). We operationalize this distinction in the context of a new methodology for constructing affordability measures that draws on the value-at-risk concept and takes account of the whole distribution of household income and house prices rather than just the median. Empirically we find that the distinction between purchase and repayment affordability can be pronounced. In the Sydney prime mortgage market over the period 1996–2006, repayment affordability deteriorated very significantly while purchase affordability remained quite stable. This difference can be attributed to the loosening of credit constraints in the mortgage market which it seems has carried through primarily into higher house prices rather than an improvement in purchase affordability. We also show how median house-price-to-income ratio measures of affordability can be extended to take account of the whole distribution of income and house prices, and how as a result of differential skewness in the house price and income distributions the housing affordability problem may be significantly worse for lower income households than suggested by standard median measures.  相似文献

We evaluate the effect of a 2003 reform in the Spanish income tax on fertility and the employment of mothers with small children. The reform introduced a tax credit for working mothers with children under the age of three, while also increasing child deductions for all households with children. Theoretically, given the interplay of these two components, the expected effect of the reform is ambiguous on both outcomes. We find that the combined reforms significantly increased both fertility (by almost 5%) and the employment rate of mothers with children under three (by 2%). These effects were more pronounced among less-educated women. In addition, to disentangle the impact of the two reform components, we use an earlier reform that increased child deductions in 1999. We find that the child deductions affect mothers' employment negatively, which implies that the 2003 tax credit would have increased employment even more (up to 5%) in the absence of the change in child deductions.  相似文献

城市规划民主与公众参与   总被引:5,自引:0,他引:5  
在民主政治的基础上,公众参与既是民主政治的通俗化表达、一种权力制度,又是一种具体的社会民主形式.具体到城市规划领域,公众参与既作为一种权力制度,以一种抽象的规划权力运行机制存在,又作为具象的城市规划民主的实现形式而出现;在此意义上,城市规划民主与公众参与是一致的.公众参与只有在城市规划民主的基础上才具有实质意义.  相似文献

I construct a matching model to explain the labor market transition between employment, unemployment and nonparticipation, and evaluate the quantitative effects of firing costs. The model has several features that are distinguished from previous studies: endogenous labor force participation, different job-search decisions and imperfect insurance markets. I find that the model is able to account for the U.S. labor market, especially the gross labor-force transition rates. I also find that firing costs as a type of firing tax have a negative effect on the layoff rate, the job-finding probability and the participation rate. In particular, the effect of a decrease in the job-finding probability is greater than the effect of a decrease in the layoff rate, and this results in an increase in the unemployment-to-population ratio. Finally, firing costs make individuals' job tenures longer and skew the asset distribution to the right.  相似文献

基于中国综合社会调查(CGSS2015)数据,采用广义分层线性模型方法,实证分析了我国城市化进程中城市原住民、城市新移民及农民工等三个不同群体的体育参与差异。结果显示:城市化进程与大众体育参与率之间呈U型关系;在城市化初期阶段,因城市人口快速增长引致的体育公共资源挤压对城市原住民体育参与的负向影响相对较小,而对城市新移民和农民工体育参与的负向影响较大;城市化过程中人均体育场馆面积和人均体育经费投入的增加对三个群体的体育参与均有显著的促进作用,但农民工从体育场馆和体育经费投入中获得的体育参与回报最低。  相似文献

Previous studies have identified the value-added potential of venture capitalist monitoring in the initial public offering (IPO) market. We test this proposition by comparing the post-issue operating performance of venture capitalist-backed IPOs with a matched sample of non-venture capitalist-backed IPOs. We find that venture capitalist-backed IPO firms exhibit relatively superior post-issue operating performance compared to non-venture capital-backed IPO firms. Further, the market appears to recognize the value of monitoring by venture capitalists as reflected in the higher valuations at the time of the IPO. Finally, we find that proxies for the quality of venture capitalist monitoring are positively related to post-issue operating performance.  相似文献

We consider a model of interdependent efforts, with linear interaction and lower bound on effort. Our setting encompasses asymmetric interaction and heterogeneous agents’ characteristics. We examine the impact of a rise of cross-effects on aggregate efforts. We show that the sign of the comparative static effects is related to a condition of balancedness of the interaction. Moreover, we point out that asymmetry and heterogeneous characteristics are sources of non-monotonic variation of aggregate efforts.  相似文献
