Abstract Export processing zones (EPZs) are like islands of globalization. Much of the literature on EPZs and export-oriented industries (EOIs) notes a preponderance of women who are constructed as “cheap,” “nimble fingered,” and “docile” labor. This literature is dominated by socialist feminist thinkers, and this paper argues that there is a need to incorporate the insights of postmodern feminist thinkers. The article focuses on the role that language, discourse, and subjectivity play in the gendering process in handmade jewelry production in the Noida Export Processing Zone (NEPZ) and in the ranch production units related by common ownership in Delhi, India. It thus gives “voices” to women and men, and brings out their agency in structuring the labor market. The study confirms that gender division of labor is a product of discursive and material practices that are reproduced through discourses into which different actors invest, and that feed into the gendered subjective identities of these actors. 相似文献

We examine changes in the association between auditor type (Big 4, Second‐Tier, and Other non‐Big 4) and perceived financial reporting credibility in the wake of events (e.g., Andersen's failure, the implementation of SOX, creation of the PCAOB, etc.) which led to significant growth in Second‐Tier client portfolios and increased scrutiny of Second‐Tier audit practices. Our results reveal that financial reporting credibility of Second‐Tier clients was lower than that of Big 4 clients and was indistinguishable from that of Other non‐Big 4 clients pre‐Andersen. However, post‐Andersen, we find that financial reporting credibility of Second‐Tier clients is higher than that of Other non‐Big 4 clients and is indistinguishable from that of Big 4 clients. We expect that our results will be of interest to regulators, both in the United States and in the European Union, who have expressed concerns about the current state of competition in the audit market, management and boards of directors that are contemplating switching to a Second‐Tier audit firm, and academics investigating quality differences among audit firm types. 相似文献

订单时间是影响供应成本的主要因素,合理的进行时间资源调度更是供应成本优化的关键所在。现有的第四方物流(Fourth Party Logistics,4PL)路径优化研究只关注物流环节的时间和成本因素,没有与物流上一环节的整合。本文提出将4PL服务拓展到客户的生产环节,在供应商的生产时间窗约束下,构建模型得到生产时间与物流时间的最优组合方案使供应商供应成本最低。最后基于一个实例的分析,验证了该模型能有效帮助4PL为客户提供最优供应方案。 相似文献

We model real exchange rate, nominal exchange rate, and relative price volatility using real and nominal factors. We analyze these volatility measures across developing and industrialized countries. We find that the inclusion of nominal factors achieves a sizable reduction in the real exchange rate volatility spread between developing and industrialized countries. In addition, we find that nominal factors matter to real exchange rate volatility in the short run and the long run, and that for developing countries, a higher share of real exchange rate volatility stems from relative price volatility. 相似文献

This paper examines the impact of Securities and Exchange Commission's Regulation Fair Disclosure (FD) on information leakage around voluntary management disclosures. We find a positive correlation between stock returns two days before and after the voluntary disclosure in the pre‐Regulation FD period, but not in the post‐Regulation FD period. After Regulation FD is implemented, pre‐announcement abnormal return as a percentage of total return decreases by 26.1% (21.4%) for large firms with good (bad) news, suggesting that the amount of information leakage reduces for these firms. These findings provide support for the premise and the intended purpose of the regulation for large firms. 相似文献
