A comparison of Ad valorem and per unit taxes in regulated monopolies

This paper compares the output and revenue effects in the rate-of-return regulated monopoly model. Both the ad valorem and the unit tax generally decrease the use of capital, and as such, reduce the output and raise the price. In addition, it is shown that Suits and Musgrave's conclusion of higher revenue of an ad valorem tax at a given output can apply to a regulated monopolist if the marginal product of labor under the ad valorem tax is greater than or equal to that under the unit tax. Similarly, their second conclusion, that for a given tax revenue an ad valorem tax has a larger output than a unit tax rate before the revenue-maximizing tax rate, can also apply to the regulated monopolist.     

Hedonic models and air pollution: Twenty-five years and counting

This paper reports a meta analysis of how effectively hedonic property models have detected the influence of air pollution on housing prices. Probit estimates are reported describing how data, model specification, and local property market conditions in cities represented in thirty-seven studies influence the ability of hedonic models to uncover negative, statistically significant relationships between housing prices and air pollution measures.Partial support for this research was provided by the Russell Sage Foundation. Thanks are due David Cordray, Heidi Hartman, and Larry Hedges of the Foundation's Meta-Analysis Panel for constructive comments, to Ray Palmquist for suggestions and assistance in assembling the results from his studies, to Rick Freeman and Tom Tietenberg and two anonymous referees for comments on the research, and to Barbara Scott for constructive editing of earlier drafts of this paper.

IPO anomalies and innovation capital

Innovation capital are typically expensed and/or unrecognized as assets under current generally accepted accounting principles. This results in accounting-related information asymmetry. This paper examines the association of innovation capital (as measured here by the proxies of R&D expenditures and granted patents) and initial public offerings (IPO) anomalies. These anomalies include initial IPO underpricing, duration of honeymoon (a distinct feature of the Taiwanese IPO environment), and long-term performance. The theoretical model underlying this research is a signaling model. The results indicate that more innovative firms are more likely to be underpriced, and have longer honeymoon periods than less innovative firms. Further, the more innovative firms have positive and growing long-term market-adjusted returns. This stands in contrast to the declining long-term stock performance of initial public offering firms that is evidenced in the literature. We conclude that pre-IPO research and development expenditures disclosed in the IPO prospectus, official monthly reports of newly developed patents released to the public, and the frequency of patent citations significantly signal both underpricing and future market performance of IPO firms in Taiwan.     

Impact of sales force automation on technology-related stress, effort, and technology usage among salespeople

This study unveils factors affecting sales force automation (SFA) technology usage by salespeople. It differs from previous research by: (1) proposing a model that examines the consequences of task complexity on role perceptions and technology usage, and (2) understanding the negative repercussions of SFA technology on the user. The proposed model was tested using data from 150 salespeople employed by a national organization. The results suggest that integration of SFA technology induces adverse role perceptions in salespeople. However, controlling for extraneous variables, effort is significantly related to salespeople's usage of technology. Key managerial implications for theory and practice are discussed.     

农民工返乡创业发展规律、制约瓶颈与对策思考——基于湖北省15县67名返乡创业者的纪实调查

返乡创业是农民工对输出地与输入地的投资成本与效益比较后的理性选择。农民工返乡创业主要以中小企业或个体的多行业经营分布为主。农民工返乡“创业潮”形成的两个阶段在兴办企业的资金来源、产业结构和销售渠道等方面差异较大。由于农民工自身素质和条件以及外在环境制约着民工的创业发展,因此应从农民工自身素质的提高和创业环境的优化两方面着手促进农民工返乡创业。
