ECONOMIC SEARCH: AN EXPERIMENTAL STUDY

This paper presents results of experiments designed to test several of the hypotheses present in the theoretical literature on "optimal" economic search. First we test whether the subjects (searchers) actually search for wages in ways that are consistent with setting an optimal reservation wage. We then proceed to determine experimentally the effects of risk aversion, increased search costs, changes in risk (brought about by a mean-preserving transformation of the distribution of wage offers), the presence or absence of recall, the existence of a finite horizon, and the searcher's state of knowledge about the underlying distribution of wages. In general, we find that the searchers exhibit behavior that is consistent with that predicted by theory. Differences between risk neutral and risk averse searchers are found, and the responses of both groups to changes in search costs, in the degree of risk, or in the state of knowledge are consistent with theoretical predictions.     

RETURNS TO FIELD OF STUDY VERSUS SCHOOL QUALITY: MBA SELECTION ON OBSERVED AND UNOBSERVED HETEROGENEITY

While a substantial literature has established returns to college major and to school quality, we offer the first such estimates for Master's of Business Administration (MBAs). To control for their nonrandom selection of fields, we estimate the returns to MBA concentrations using both ordinary least squares (OLS) with detailed control variables and including individual fixed effects. We find approximately 7% returns for most MBAs but roughly double that for finance and management information systems (MIS). Thus, MBA area of study can matter as much or more than program quality: only attending a top 10, but not 11‐25, MBA program trumped studying finance and MIS at a nontop 25 program.

Job Satisfaction and Organizational Structure: A Comparative Study of Nine Social Service Departments

Summary The authors investigated the relationship between aspects oforganizational structure and job satisfaction as experiencedby personnel employed in nine social service departments. Aftera series of unstructured interviews from 28 respondents in oneauthority, interview schedules were used for three distinctgroups of 603 respondents in nine organizations: those makingexecutive decisions, those making supervisory assessments andthose primarily concerned with client interaction. The bestpredictors of organizational structure were dimensions of centralizationand formalization which related significantly but negativelyto job satisfaction. The relevance of these findings is discussedin relation to the rapid growth of social services and the effectit has had on social workers and other employees.     

对话口译中的权力——口译社会学解读

传统观念认为,职业译员应该是透明、隐身、被动、中立和超然的,这种理想化的译员角色建构却屡屡在现实对话口译事件中遭遇解构。对话口译可视为由当事双方和译员共同构成、发生在一定社会语境下的三向互动式交际事件,从福柯的权力观以及温格和布隆马尔特等人的相关理论出发,译员作为交际活动的共同建构者,是一个权力角色。尽管译员不具备体制性权力,但由于他掌握着双语双文化资源,却拥有交际过程中的权力,这可以从译员选择成为共同谈话人、赋权角色、采取非中立立场的社会行为表现出来。从真实口译场景中引证,聚焦译员的言语和非言语行为,特别是定位和注视等行为,分析译员的权力运作。     

The Birth of a Noble Tea Country: on The Geography of Colonial Capital and The Origins of Indian Tea

This paper looks at the origins of the British tea industry of India from the standpoint of colonial and semicolonial involvement in, respectively, British India and Qing China. The imposition of the tea industry in Assam was integrally tied to the wars in East Asia fought in order to open markets for the movement of opium and other commodities. British officials championed both policies in the name of modern economic progress, liberalizing trade with the Qing and establishing a productive industry in Assam. The agricultural science of political economy aimed to extract the value of various objects which could then be united in a land hitherto considered a wasteland. Plants, soil and labor were each viewed as isolatable things whose values were objective and calculable. Such static representation, however, was already belied by the dynamic process of gathering and transporting these things across the vast and unevenly developed regions of Asia, ultimately valorizing them as a breakfast drink commodity enjoyed worldwide. The origins of the Assam tea plantations, mirroring developments elsewhere, relied upon spatio-economic connections that force us to reevaluate how the specific histories of British India, Qing China and Southeast Asia are inseparably linked.     

THE IMPACT OF ENTERPRISE INFORMATION TECHNOLOGY ADOPTION ON OPERATIONAL PERFORMANCE: AN EMPIRICAL INVESTIGATION

This paper presents the results of a natural experiment conducted at a U.S. high‐tech manufacturer. The experiment had as its treatment the adoption, at a single point in time, of a comprehensive enterprise information system throughout the functional groups charged with customer order fulfillment. This information technology (it) adoption was not accompanied by substantial contemporaneous business process changes. Immediately after adoption, lead time and on‐time delivery performance suffered, causing a “performance dip” similar to those observed after the introduction of capital equipment onto shop floors. Lead times and on‐time delivery percentages then improved along a learning curve. After several months, performance in these areas improved significantly relative to preadoption levels. These observed performance patterns could not be well explained by rival causal factors such as order, production, and inventory volumes; head count; and new product introductions. Thus, this longitudinal research presents initial evidence of a causal link between IT adoption and subsequent improvement in operational performance measures, as well as evidence of the timescale over which these benefits appear.
