“他者”眼光的局限——读杰华《都市里的农家女——性别、流动与社会变迁》

作为一个异域文化的观察者,杰华在研究“城里人怎样看待女性农民工”的时候,多有创获。但是,杰华在研究“她们怎样看待她们自己”的时候,则在设计调查问卷、分析调查结果中,不免带了过多的西方人的眼光,让人看出,调查者与被调查者之间,由于生存环境的不同,而存在非常大的文化隔膜。

A day without a search engine: an experimental study of online and offline searches

With the evolution of the Web and development of web-based search engines, online searching has become a common method for obtaining information. Given this popularity, the question arises as to how much time people save by using search engines for their information needs compared to offline sources, as well as how online searching affects both search experiences and search outcomes. Using a random sample of queries from a major search engine and a sample of reference questions from the Internet Public Library (IPL), we conduct a real-effort experiment to compare online and offline search experiences and outcomes. We find that participants are significantly more likely to find an answer on the Web (100 %), compared to offline searching (between 87 % and 90 %). Restricting our analysis to the set of questions in which participants find answers in both treatments, a Web search takes on average 7 (9) minutes, whereas the corresponding offline search takes 22 (19) minutes for a search-engine (IPL) question. Furthermore, while raters judge library sources to be significantly more trustworthy and authoritative than the corresponding Web sources, they judge Web sources as significantly more relevant. Balancing all factors, we find that the overall source quality is not significantly different between the two treatments for the set of search-engine questions. However, for IPL questions, we find that non-Web sources are judged to have significantly higher overall quality than the corresponding Web sources. In comparison, for factual questions, Web search results are significantly more likely to be correct (66 % vs. 43 %). Lastly, post-search questionnaires reveal that participants find online searching more enjoyable than offline searching.     

Unemployment and product market competition in a Cournot model with efficiency wages

This paper analyzes the impact of product market competition on unemployment, wage and welfare in a model where unemployment is caused by the efficiency wage consideration and oligopolistic firms compete in quantity. It is shown that while more intense competition in the product market increases output and reduces price, it does not necessarily lead to a lower unemployment rate or a higher wage for workers. Depending on the technologies, the relationship between the intensity of competition and the level of employment (respectively, wage, welfare) is not always monotonic, and, in some instances, has an inverted U‐shape.     

Unemployment and welfare consequences of international outsourcing under monopolistic competition

This paper challenges the conventional academic view that international outsourcing is just another form of gainful trade. Contrary to that view, we show that labour‐service outsourcing can reduce the high‐wage country's welfare even when product‐market trade is beneficial, within a model that combines involuntary unemployment and monopolistic competition. Outsourcing's impact on welfare is worsened by a definite loss of jobs and a possible contraction in the range of varieties produced worldwide. While owners of capital benefit from outsourcing under certain conditions, labour's welfare always falls.
