EVALUATING THE DISTRIBUTIONAL EFFECTS OF FISCAL POLICIES USING QUANTILE REGRESSIONS

The objective of this paper is to propose and apply a new method to evaluate the distributional impact of fiscal policies and potential marginal reforms. The econometric tool adopted is structural quantile treatment effects regression, which allows a complete picture of the effects of the fiscal policy of interest on households with different incomes, abilities, and needs. We apply this method to personal income taxation and non‐cash transfers in Italy for the year 2004. Our estimates suggest that, although heterogeneous, the redistributive effects of the potential fiscal reforms are almost zero.     

Investor opinion divergence and post-repurchase announcement stock price drift

This study examines whether investor opinion divergence is a significant determinant of post-repurchase abnormal returns. We examine the effect using abnormal trading turnover (ATO) ratio as a proxy for investor opinion divergence. While the OLS regression results show that investor opinion divergence is not related to post-repurchase performance, the quantile regression results show that the effect of investor opinion divergence on post-repurchase performance is not homogeneous across various quantile levels of post-repurchase performance. We find a positive relation between ATO ratio and post-repurchase performance for firms with lower-to-middle performance groups. For firms with middle-to-higher post-repurchase performance, pre-repurchase stock undervaluation is a key determinant of the post-repurchase performance.     

Socioeconomic Effects on the Stature of Nineteenth-Century US Women

Using a new source of nineteenth-century state prison records and robust statistics, this study contrasts the effects of social conditions on the stature of comparable African American and white women during the economic development of the United States. Across the stature distribution, Great Lakes, Plains, and Southern women were taller than women with other US and international nativities. Women from the Northeast and Middle Atlantic were the shortest within the US, but were taller than British and European immigrants. White women were consistently taller than black women. Stature also varied over time with industrialization and emancipation. Across the stature distribution, women in outdoor, unskilled occupations were taller than women in indoor, skilled occupations. These results show that US women's average statures reflect net nutritional conditions that are not available in traditional measures of economic well-being.     

External and Internal R&D,Capital Investment and Business Performance in the Spanish Agri‐Food Industry

We examine the effects of external and internal expenditure on research and development on the business performance of industrial agri‐food enterprises. For this purpose, a data sample from the Encuesta de Estrategias Empresariales en España (Survey of Business Strategies in Spain) was used, which includes information on more than 400 businesses over the period 2000–2008. The econometric analysis uses quantile regressions to address the vast asymmetry of the variables and to identify non‐linear relationships. The results reveal interesting new findings on the impacts of R&D on the agri‐food industry. The most evident, although not the most immediately apparent, relationship concerns the positive effects of external R&D on business performance. Internal R&D was also revealed to be an important way of enhancing the productivity of SMEs. In addition, the modernisation of the production process through investment in capital goods continues to be the main path to improve competitiveness. However, support was found neither for the inverse relationship, that is the most profitable firms are those that spend the most on R&D, nor for complementarity between external and internal R&D. The latter would imply that the bulk of Spanish agri‐food firms have at most the capacity for only one type of R&D.     

欠发达地区农民消费与持久收入假说——以重庆为例

论文采用了弗里德曼和苏良军的分解方法得到持久收入、暂时收入,并运用分位数回归(quantile regression,QR)方法验证持久收入假说,结果表明持久收入假说失灵。进一步实证分析发现,超过60%的重庆农村居民按照当期收入消费,重庆农村居民的消费对当期收入表现出相当程度的过度敏感性,这是持久收入假说失灵的原因。研究还发现未来收入的不确定性对重庆农村居民消费具有显著性影响,而流动性约束却没有显著性影响。     

Small Area Quantile Estimation

Sample surveys are widely used to obtain information about totals, means, medians and other parameters of finite populations. In many applications, similar information is desired for subpopulations such as individuals in specific geographic areas and socio‐demographic groups. When the surveys are conducted at national or similarly high levels, a probability sampling can result in just a few sampling units from many unplanned subpopulations at the design stage. Cost considerations may also lead to low sample sizes from individual small areas. Estimating the parameters of these subpopulations with satisfactory precision and evaluating their accuracy are serious challenges for statisticians. To overcome the difficulties, statisticians resort to pooling information across the small areas via suitable model assumptions, administrative archives and census data. In this paper, we develop an array of small area quantile estimators. The novelty is the introduction of a semiparametric density ratio model for the error distribution in the unit‐level nested error regression model. In contrast, the existing methods are usually most effective when the response values are jointly normal. We also propose a resampling procedure for estimating the mean square errors of these estimators. Simulation results indicate that the new methods have superior performance when the population distributions are skewed and remain competitive otherwise.     

The quantile dependence of commodity futures markets on news sentiment

Focusing on energy commodities, industrial metals, and gold, this paper examines the degree to which commodity futures returns depend on news sentiment under various market conditions, and the structure of that dependence. We observe an asymmetric market reaction to positive and negative news sentiment, which changes in periods of financial turmoil. The quantile regression analysis shows that news sentiment's influence on the futures returns follows an upward trend at higher percentiles. This structure flattens for positive news during the global financial crisis, while the slope for the negative component steepens in backwardation periods.     

The effect of fiscal system reform on fiscal policy outcomes

We investigate how reform in governmental accounting affects fiscal policy outcomes including debt, balance, and fiscal transparency. Since a change from cash to accrual accounting can be regarded as a natural experiment among governments, a fixed-effects model is exploited. We discover that the change diminishes debt in developed countries, but expands it in less-developed ones, with strong effects in highly indebted countries. The change improves balance in developed countries and worsens it in less-developed countries, which is significant for developed countries with large deficits. Transparency is improved only in less transparent developed countries.     

THE DETERMINANTS OF PRICE IN ONLINE AUCTIONS: MORE EVIDENCE FROM QUANTILE REGRESSION

This study explores how seller reputations affect auction prices and concludes that earlier findings may be biased due to the misspecification of seller reputation. This paper contributes to the literature by offering significant empirical evidence using Taiwanese internet auction data. Our study reveals that the influence of seller reputations on auction prices is significant, irrespective of the assumptions of linear or non‐linear relationships with price. However, failure to consider the non‐linear setting of seller reputation leads us to underestimate the impact of reputation when the seller's reputation score is low, but overestimates it when the seller's reputation becomes high. Using quantile regression, this study finds evidence of considerable differences in their impact on auction prices that are dependent on the distribution of price levels.
