This paper uses a logit model to test whether voters will alter their support for incumbents in state level elections, specifically gubernatorial and state house and senate elections, when local (i.e., county) economic conditions are observed. The results signify that voters do hold the incumbent party responsible for economic conditions. Furthermore, voters tend to place more emphasis on unemployment levels than on real personal income indicating that incumbent politicians might want to engage in policies that put people to work rather than on policies that raise income. The results also suggest that voters did not hold their state house and senate representative as responsible for local economic conditions as they did the governor. 相似文献

We investigate whether productivity differences explain why some manufacturers sell only to the domestic market while others serve foreign markets through exports and/or FDI. When overseas production offers no cost advantages, our model predicts that investors should be more productive than exporters. An extension allowing for low-cost foreign production can reverse this prediction. Data for 1070 large Japanese firms reveal that firms that invest abroad and export are more productive than firms that just export. Among overseas investors, more productive firms span a wider range of host-country income levels. J. Japanese Int. Economies 17 (4) (2003) 448–467. 相似文献

A bstract . Economists have long studied the determinants and effects of income transfers. This article examines an indirect effect of welfare payments on participating individuals: an increase in the incidence of sexually transmitted disease ( STD ) rates.
Several studies have found a significant and positive link between the size of welfare benefits and out-of-wedlock fertility rates. Higher welfare payments reduce the cost of bearing and raising a child, and thus reduce the full cost of engaging in unprotected sex. An unintended consequence of unprotected sex is exposure to contagious diseases. This implies that states with higher welfare payments per child will experience higher rates of STDs.
We test this hypothesis using statewide data on the incidence of three types of bacterial STDs, chlamydia, gonorrhea, and syphilis, for the years 1994 through 1998. The empirical specification is based on the standard microeconomic model of utility-maximizing behavior. The included explanatory variables are demographic proxies reflecting differences in state population characteristics. These characteristics capture unobservable or intrinsically unmeasureable differences in the perceived costs and benefits of engaging in unprotected sex.
The explanatory variable of primary interest is the size of the real welfare payment per recipient. Our empirical results indicate that states with higher real welfare payments are associated with greater rates of STDs. 相似文献

Value-at-Risk Prediction: A Comparison of Alternative Strategies 总被引:4,自引:0,他引:4

Given the growing need for managing financial risk, risk predictionplays an increasing role in banking and finance. In this studywe compare the out-of-sample performance of existing methodsand some new models for predicting value-at-risk (VaR) in aunivariate context. Using more than 30 years of the daily returndata on the NASDAQ Composite Index, we find that most approachesperform inadequately, although several models are acceptableunder current regulatory assessment rules for model adequacy.A hybrid method, combining a heavy-tailed generalized autoregressiveconditionally heteroskedastic (GARCH) filter with an extremevalue theory-based approach, performs best overall, closelyfollowed by a variant on a filtered historical simulation, anda new model based on heteroskedastic mixture distributions.Conditional autoregressive VaR (CAViaR) models perform inadequately,though an extension to a particular CAViaR model is shown tooutperform the others. 相似文献

In an empirical study of teleworking practices in small and medium-sized enterprises (SMEs) in west London, organisational factors such as management attitudes, worker autonomy and employment flexibility were found to be more critical than technological provision in facilitating successful implementation. Consequently, we argue that telework in most SMEs appears as a marginal activity performed mainly by managers and specialist mobile workers. 相似文献

An empirical investigation of the effects of impact fees on housing and land markets 总被引:1,自引:0,他引:1
This paper presents the results from estimating the effects of development impact fees on the prices of new and existing single-family homes and undeveloped residential land using unique data for Dade County, FL. The results show that an additional US$1.00 of fees increases the price of both new and existing housing by about US$1.60 and reduces the price of land by about US$1.00. These findings are shown to be consistent with the new view but not the old view theory of impact fee incidence. 相似文献

Effective interfirm collaboration is an incresingly significant factor in technological innovation. A wide and complex range of options exists within collabotative arrangements which affect the outcome and rewards for both partners. Firms are often unaware of the strategic implications of collaborative ventures. While some large firms may be invloved in strategic alliances at the corporate level in order to establish or maintain competitiveness, many remain unaware or unconvinced of the potential for the generation of innovations through collaborations with small, flexible, 'hi-tech” firms. the pace of change and the challenge of international competition threatens Western European firms with a 'technology gap' within a 'disorganized capitalist' setting. Various forms of interfirm cooperation within and across natinal boundaires may be important responses to such uncertainty and amy ultimately provide successful strategic remedies to the situation. This article presents the findings of a recently completed research project in which 27 pairs (mostly small/large) of collaborating, innovative firms were studied in order to examine the strategic and operational issues involued in interfirm research cooperation. Whilst highlighting the advantages of collaboration, and the potential problems for both the small and the large partner, we argue that the adoption of 'cooperative game' rules id vital for successful collaborative innovation. Additionally, we attempt to posit our findings within the current debate on organized/disorganized capitalism. 相似文献
