Economists and other social scientists are calling for a reassessment of the impact of international trade on labor markets
in developed and developing countries. Classical models of globalization and trade, based upon the international exchange
of finished goods, fail to capture the fragmentation of much commodity production and the geographical separation of individual
production tasks. This fragmentation, captured in the growing volume of intra-industry trade, prompts investigation of the
effects of trade within, rather than between, sectors of the economy. In this paper we examine the relationship between international
trade and the task structure of US employment. We link disaggregate US trade data from 1972 to 2006, the NBER manufacturing
database, the Decennial Census, and occupational and task data from the Dictionary of Occupational Titles. Within-industry
shifts in task characteristics are linked to import competition and technological change. Our results suggest that trade has
played a major role in the growth in relative demand for nonroutine tasks, particularly those requiring high levels of interpersonal
interaction. 相似文献

This paper discusses the general characteristics of online markets from a competition theory perspective and the implications for competition policy. Three important Internet markets are analyzed in more detail: search engines, online auction platforms, and social networks. Given the high level of market concentration and the development of competition over time, we use our theoretical insights to examine whether (a) leading Internet platforms have non-temporary market power and, based on this analysis, (b) whether any specific market regulation beyond general competition law rules is warranted in these three online markets. 相似文献

Attaching consumers to a brand is a cornerstone of relationship marketing as attachment increases loyalty. This research investigates another possible benefit of attachment, its potential and limits for shielding brands from firms’ ethical missteps. Merging motivated reasoning and attachment theories, two studies focus on how brand attachment influences consumer judgments of firm ethics and the emotional and behavioral consequences developing from those. A field study indicates that attachment attenuates judgments of unethical behavior, contributes to emotional ambivalence, and affects purchase intentions. A subsequent experiment corroborates these findings and shows that the buffering role of attachment is limited to conditions when the information about firm ethics is moderately rather than extremely negative. Implications focus on advancing research on ethics and emotional ambivalence in consumer brand relationships and on managerial implications. 相似文献

The risk and prevention of autoignition in underground coal storage facilities are reviewed in the light of the recent incidents of smouldering fires. Also, the opportunities are considered on the efficiency of the alternatives to prevent and extinguish closed-space fires. The complexities in avoiding and extinguishing underground fires are highlighted in the case example, describing the observations and outcome of a smouldering coal fire in the storage. The principles of self-heating and most critical factors in spontaneous combustion such as the condition and quality of coal are fairly well known, but usually only provide partial help in fire prevention. The documented cases and the case example suggest that nitrogen injection can be useful for extinguishing controllable fires. Three-phase foams and oxygen-displacing exhaust gases appear preferable against uncontrolled fires, particularly if access to the fire area is limited or impossible. Otherwise, efficient fire extinction during power plant operation can be challenging, as any air ingress tends to feed the fire and results in losses of the extinguishing agent and the heating value of coal. Methods and indicators for detecting and predicting the ignition are discussed, and improvements are suggested to enhance the storage and plant availability. 相似文献
