This paper investigates whether the voluntary decomposition of consolidated earnings disclosures into industry segments has information content in the sense that such disclosures better enable investors to predict earnings. The broad rationale underlying the experimental design is that if segment disclosure does enable investors to better predict earnings then residual abnormal returns (after controlling for unexpected earnings) surrounding the earnings announcements of firms providing segment disclosures should on average be significantly lower than a matched' group of firms that do not provide this type of disclosure. Using a short event window design, our results support this view.  相似文献

基于监狱调查数据,本文分析了农村户籍服刑人员和普通农民工之间,以及服刑人员内部在个人基本信息、性格特质和家庭背景三个维度上的差异。研究发现农民工罪犯主要参与暴力犯罪和盗窃。与农民工相比,服刑人员总体上年纪小,教育不足,认知能力和性格特征存在缺陷,兄弟姐妹多,母亲教育程度低。区分不同犯罪类型,以上特征多表现在暴力犯和盗窃犯身上;而涉毒犯和经济犯的特征为进城时间长、认知能力强和无差异的年龄及母亲教育程度。  相似文献

The effectiveness of 11 unbuilt liquid detergents and eight built liquid detergents, of varying formulations, in cleaning a standard soiled fabric in soft water (5 ppm) were evaluated. It was found that in soft water there were no significant differences between washing in warm or hot water with either type of detergent, except for a melaleuca oil based detergent which was significantly better in hot water. However, although not significant, in general, washing with unbuilt liquid detergents did give somewhat better results in both warm and hot water.  相似文献

This paper examines how market prices, volume, and traders' dividend expectations respond to public information releases in laboratory markets for a long-lived financial asset. The objective is to study deviations from the symmetric information risk-neutral rational expectations (RE) benchmark, which predicts no trade in such settings. The results of a series of double-auction and call markets are reported in which traders manage a portfolio of cash and asset shares over 15 rounds of trading. A public signal regarding the value of the liquidating dividend is released every third round, and traders' subjective expectations of the liquidating dividend are elicited each round as cash-motivated forecasts. We find that, despite the public dividend signal, traders' dividend forecasts are heterogeneous. Forecasts and prices both underreact to the public signals, with prices under-reacting more than forecasts. In general, price changes are not closely associated with public signals, and there is greater excess price volatility in double auctions than in call markets. Forty-three percent of trades are inconsistent with the trader's forecasts, and inconsistent trades occur more frequently in the double-auction markets. On average, approximately 10 percent of the outstanding shares are traded in each round, and trading volume is increasing in the mean absolute forecast revision and decreasing in the contemporaneous dispersion in forecasts. These results suggest that differential processing of the public signal and/or speculative trading for short-term gain may help to explain why symmetric information RE predictions are often not supported in empirical and experimental settings. They also suggest that market reactions to public information releases may be influenced by market microstructure.  相似文献

Predictor variables previously examined in separate studies (prior beliefs, peer pressure, family smoking, advertising, and antismoking information) were combined in a single study, surveying 246 adolescents. The variables were found to be significant predictors of smoking level, but the importance of each predictor varied by grade level, gender, and ethnicity. Overall, family smoking behavior, peer pressure, and prior beliefs were more important in predicting smoking level than were advertising and antismoking information. Public policy implications are discussed.  相似文献

In recent years, the proportion of after-hours earnings announcements has increased to more than 40%. For after-hours announcements, earnings-related volume and price changes are not observed on the Compustat or I/B/E/S earnings announcement date, but one trading day later. This study demonstrates the importance of accounting for after-hours announcements for event studies around earnings announcements.  相似文献

The objective of this research was to determine the socioeconomic characteristics of supplement users versus nonusers. Seven western states (Arizona, California, Idaho, Nevada, New Mexico, Oregon and Wyoming) were surveyed to determine the socioeconomic profile of persons who either use or do not use supplements. Results indicated that 60.2% of the supplement users were female. The largest percentage was 31–40 years of age. By most definitions, supplement users tended to be well educated. Under adverse economic conditions, only a small percentage (7%) of users would give up supplements first when asked to choose from a variety of items that were considered to be nonessential.  相似文献

Critics of globalization claim that firms are being driven by the prospects of cheaper labor and lower labor standards to shift employment abroad. Yet the evidence, beyond anecdotes, is slim. This paper reports stylized facts on the activities of U.S. multinationals at home and abroad for the years 1977 to 1999. We focus on firms in manufacturing and services, two sectors that have received extensive media attention for supposedly exporting jobs. Using firm‐level data collected by the Bureau of Economic Analysis (BEA) in Washington, D.C., we report correlations between U.S. multinational employment at home and abroad. Preliminary evidence based on the operations of these multinationals suggests that the sign of the correlation depends on the crucial distinction between affiliates in high‐income and low‐income countries. For affiliates in high‐income countries there is a positive correlation between jobs at home and abroad, suggesting that foreign employment of U.S. multinationals is complementary to domestic employment. For firms that operate in developing countries, employment has been cut in the United States, and affiliate employment has increased. To account for firm size, substitution across firms and entry and exit, we aggregate our data to the industry level. This exercise reveals that the observed “complementarity” between U.S. and foreign jobs has been driven largely by a contraction across all manufacturing sectors. It also reveals that foreign employment in developing countries has substituted for U.S. employment in several highly visible industries, including computers, electronics, and transportation. The fact that there were U.S. jobs lost to foreign affiliates in key sectors, despite broad complementarity in hiring and firing decisions between U.S. parents and their affiliates, helps explain why economists view the impact of globalization on U.S. jobs as benign despite negative news coverage for declining industries.  相似文献
