This study endeavors to enhance political marketing literature about the impact of lobbying on firm performance. Our sample is composed of 140 U.S. firms and spans the years 2007–2014 to encompass the 2007–2009 recession and the subsequent recovery period. Our findings indicate that lobbying expenses positively contribute to firm performance. Also, government contracts in both ways, dollar amount and number of government contracts, act as mediators between lobbying expenses and firm performance. In addition, organizational slack moderates the relationship between lobbying expenses and government contracts. The managerial implications suggest that lobbying expenses can be leveraged as a potent tool for firm performance. Firms with larger lobbying efforts acquired both, higher dollar amounts and a greater number of government contracts. 相似文献

Cross-sectional and time-series tests using mimicking portfolios are used to assess the exactness of the APT with(out) a residual market factor. The first factor seems to be sufficient to span the efficient set, whether the model is estimated using (un)conditional variance-covariance matrices that are (un)adjusted for nonsynchronous trading. Although the conditional standard deviations of the mimicking portfolios significantly explain the time-variability of security volatilities, the residuals of the mean equation still exhibit heteroskedasticity. Similar results are obtained for portfolios of CAPM-betaranked securities, and for randomly selected individual securities. 相似文献

城市低收入保障制度与反贫困的公共政策 总被引:2,自引:0,他引:2
赵曼 《湖北经济学院学报》2003,1(1):58-64
城市低收入保障制度实施中“应保未保”的现象较为普遍,低收入保障所需资金的缺口较大,缺乏全国统一的贫困标准使得其随意性很大。解决这一社会问题必须从近期和远期两个目标入手,近期目标是尽快遏制城市贫困人口剧增的势头,防止在深化改革的过程中出现快速增长的新生贫困人口;远期目标是立足最终消除城市贫困现象。 相似文献

Concessional Amnesty and the Politics of Immigration Reforms 总被引:1,自引:0,他引:1
Nancy H. Chau 《Economics & Politics》2003,15(2):193-224
This paper establishes a political support model of immigration reforms. The analysis highlights the distinction between border enforcement and employer sanction measures in that the former can be more aptly characterized as an income transfer from employer to native labor interests, whereas the latter generates deadweight losses that are borne entirely by producers. We show that while amnesty may appear to run contrary to the original intent of the immigration reform, it may nevertheless facilitate rent capture by the politician by "wiping the slate clean" and reducing the deadweight loss of employer sanction measures. 相似文献

The paper addresses the question of whether trade restrictiveness impacts economic performance, via a trade restrictiveness index that is decomposable into a trade distortion and a domestic distortion component. The paper builds on the Anderson and Neary price index measure of trade distortion, in evaluating trade restrictiveness via a distance function approach. This is accomplished by adding a “dual” version to their trade restrictiveness price index, based on distance functions that scale output quantities. The authors compute the trade restrictiveness quantity index (TRQI) using a parametric frontier approach to model the production side of the economy, and a panel of information on the agricultural sector of a set of European Community countries. The results suggest that the use of TRQI makes a considerable difference to interpretations of the efficiency impact of agricultural trade policies in EC countries, as compared to policy‐oriented aggregates or result‐oriented measures of trade restrictiveness. 相似文献

Do the Forward Sales of Real Estate Stabilize Spot Prices? 总被引:1,自引:0,他引:1
S. K. Wong C. Y. Yiu M. K. S. Tse K. W. Chau 《The Journal of Real Estate Finance and Economics》2006,32(3):289-304
We examine the effect of forward sale (pre-sale) activities on the volatility of spot prices in the real estate market. The
abundance of pre-sales data and major changes in regulatory control on the pre-sale market during the 90's in Hong Kong allow
us to undertake empirical tests using Hong Kong's real estate data. Our results show that the volatility of spot prices increased
significantly after forward sales were severely dampened by regulatory control measures introduced in 1994, but decreased
again when the measures were partly relaxed in 1998. The results contribute to the long lasting debate on whether the introduction
of a futures market reduces the volatility of spot prices. Previous studies were mainly conducted in markets with low transaction
costs, notably financial markets. By utilizing the unique regulatory changes in the pre-sale market of Hong Kong, we are able
to conduct an experiment on the conditional volatility of spot prices in a high information-cost environment, thereby shedding
light on the important role of forward housing contracts in providing price expectation information for spot trading. 相似文献
