部分农村地区环境持续恶化且不被重视是不争的事实,在改变农村地区环境现状、切实保护农民环境权这一问题上。应从文化传统、社会经济、法律制度、基层行政举措等多个维度进行综合考量才能找出行之有效的解决之道。  相似文献

Prior research indicates that analysts do not fully adjust for the general downward bias in earnings guidance issued by management. We report the results of two experiments designed to investigate how guidance track record and analysts’ incentives jointly explain the extent to which analysts adjust for guidance bias. Our results suggest that analysts with accuracy incentives adjust for management’s track record of downwardly biased guidance when the bias is relatively small (one cent), but those with relationship incentives do not. Furthermore, the difference in adjustment is larger when the bias track record is inconsistent than when it is consistent. Also, when guidance bias is larger (two cents) relative to smaller (one cent), analysts with relationship incentives partially adjust, as they appear to strike a balance between accuracy and their desire to please management. These findings hold implications for investors, regulators, and the interpretation of prior research.  相似文献

This paper applies the regression quantile approach developed by Koenker and Xiao (2004) to investigate the dynamic behavior of inflation in 12 OECD countries. By analyzing the behavior in a wide range of quantiles, this method allows us to quantify the influence of various sizes of shocks that hit the inflation, and is able to capture possible asymmetric adjustment of the inflation towards to its long-run equilibrium. It therefore sheds new lights on the inflation dynamics compared with the conventional unit root methodologies. Our results suggest that generally, the inflation rates are not only mean-reverting but also exhibit asymmetries in their dynamic adjustments, in which large negative shocks tend to induce strong mean reversion, and on the contrary, large positive shocks do not. Policy implications related to the empirical findings are also provided.  相似文献

Corporate lobbying activities are designed to influence legislators, regulators and courts, presumably to encourage favorable policies and/or outcomes. In dollar terms, corporate lobbying expenditures are typically one or even two orders of magnitude larger than spending by Political Action Committees (PAC), and, unlike PAC donations, lobbying amounts are direct corporate expenditures. We use data made available by the Lobbying Disclosure Act of 1995 to examine this more pervasive form of corporate political activity. We find that, on average, lobbying is positively related to accounting and market measures of financial performance. These results are robust across a number of empirical specifications. We also report market performance evidence using a portfolio approach. We find that portfolios of firms with the highest lobbying intensities significantly outperform their benchmarks in the three years following portfolio formation.  相似文献

Abstract

Over the past two decades, there has been a proliferation of research on human resource management (HRM) in Chinese state-owned enterprises (SOEs) as a result of the wide-reaching state-sector reform of the late 1980s. This article aims to provide a systematic review of literature on this topic and capture the nature of HRM in Chinese SOEs, both in research and practice. The article draws on 178 studies from 43 English academic journals over a period of 25?years (1993–2017). In analysing this literature and by taking stock of theoretical frameworks, research methods, themes and analysis of academic articles in this area, we have gained a number of insights. The study has found that the research methods used have shifted from qualitative and interpretive methodology toward quantitative and sophisticated modelling. A further insight is that there has been a relatively heavy reliance on institutional theory in the earlier studies reviewed, and since then a switch towards organizational behaviour perspectives. The level of analysis has moved from macro to micro level and thematic foci have become more diverse and complex. We highlight a number of avenues, theoretical and empirical, for future studies in this field.  相似文献

This paper generalizes Rubinstein and Wolinsky's (1987) model of middlemen (intermediation) by incorporating production and search costs, plus more general matching and bargaining. This allows us to study many new issues, including entry, efficiency, and dynamics. In the benchmark model, equilibrium exists uniquely and involves production and intermediation for some parameters but not others. Sometimes intermediation is essential: the market operates if and only if middlemen are active. If bargaining powers are set correctly equilibrium is efficient; if not there can be too much or too little economic activity. This is novel, compared to the original Rubinstein–Wolinsky model, where equilibrium is always efficient.  相似文献

The design of reverse logistics network has attracted growing attention with the stringent pressures from environmental and social requirements. In general, decisions about reverse logistics network configurations are made on a long-term basis and factors influencing such reverse logistics network design may also vary over time. This paper proposes dynamic location and allocation models to cope with such issues. A two-stage stochastic programming model is further developed by which a deterministic model for multiperiod reverse logistics network design can be extended to account for the uncertainties. A solution approach integrating a recently proposed sampling method with a heuristic algorithm is also proposed in this research. A numerical experiment is presented to demonstrate the significance of the developed stochastic model as well as the efficiency of the proposed solution method.  相似文献
