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.     

CALIFORNIA'S EXPORTS AND THE 2004 OVERSEAS OFFICE CLOSURES

Estimating the impact of state import promotion programs on exports is difficult because of a simultaneity program. The 2003 California budget crisis provides a natural experiment allowing for an unbiased estimate. Due to the crisis, California closed all 12 overseas offices on 1 January 2004. Applying the differences‐in‐differences estimator to a sample of 44 countries over eight years yields an estimated 2%–3% increase in exports if the offices remained open. But this estimate is not statistically significant. Therefore, I find no statistical evidence that California's overseas offices increased exports. (JEL F13, H76, O24)     

BELIEVING IN ECONOMIC THEORIES: SEX, LIES, EVIDENCE, TRUST, AND IDEOLOGY

Political economics views heterogeneity of political preferences largely as a reflection of heterogeneity in valuations of known policy outcomes. Voters, however, may be uncertain about policy outcomes, in part, because of uncertainty about how the economic world actually works. Heterogeneity of people's beliefs about how well economic theories predict outcomes could then affect policy through democratic institutions. Using a combination of experimental and survey techniques drawn from economics and social and political psychology, we examine several potential sources of heterogeneity in beliefs about the predictive content of supply and demand theory, with a particular focus on the role of ideology.

Two‐Sample Bootstrap Hypothesis Tests for Three‐Dimensional Labelled Landmark Data

Abstract. We investigate resampling methodologies for testing the null hypothesis that two samples of labelled landmark data in three dimensions come from populations with a common mean reflection shape or mean reflection size‐and‐shape. The investigation includes comparisons between (i) two different test statistics that are functions of the projection onto tangent space of the data, namely the James statistic and an empirical likelihood statistic; (ii) bootstrap and permutation procedures; and (iii) three methods for resampling under the null hypothesis, namely translating in tangent space, resampling using weights determined by empirical likelihood and using a novel method to transform the original sample entirely within refection shape space. We present results of extensive numerical simulations, on which basis we recommend a bootstrap test procedure that we expect will work well in practise. We demonstrate the procedure using a data set of human faces, to test whether humans in different age groups have a common mean face shape.     

Exploring cultural economies of internationalization: the role of ‘iconic individuals’ and ‘brand leaders’ in the globalization of headhunting

Understanding the internationalization of professional services like advertising, architecture, accounting, consulting and legal services continues to attract considerable attention in academic and policy circles. Research in geography and management studies has emphasized the different organizational strategies adopted by firms as they seek to develop and maintain a competitive position within an increasingly global economy. In this article we develop a new strand in this literature by adopting a cultural economy approach to argue that an important, yet comparatively neglected, aspect of the internationalization strategies of transnational professional service firms is the role of certain ‘iconic individuals’ and ‘brand leaders’ in influencing the practice of internationalization. Drawing on empirical research into the burgeoning European executive search (headhunting) industry we identify a cadre of such individuals and brand leaders that act as resources other firms leverage when internationalizing. This highlights the importance of a cultural economy perspective in theories of the internationalization of professional services and its value in moving discussions beyond purely economic analyses of competitive advantage.     

BILATERAL OLIGOPOLY IN POLLUTION PERMIT MARKETS: EXPERIMENTAL EVIDENCE

We experimentally investigate behavior in a bilateral oligopoly using a supply function equilibria model discussed by Klemperer and Meyer (1989), Hendricks and McAfee (2010), and Malueg and Yates (2009). We focus on the role that market size and the degree of firm heterogeneity have on the market equilibrium. Our results indicate that subjects within the experiment recognize the strategic incentives in a bilateral oligopoly, but they do not exploit these incentives to the exact magnitude predicted by theory. We find weaker support for predicted market outcomes, as market efficiency does not depend on market size, and in some cases buyers or sellers are more successful at extracting the rents from the market.

LEAN AND GREEN? AN EMPIRICAL EXAMINATION OF THE RELATIONSHIP BETWEEN LEAN PRODUCTION AND ENVIRONMENTAL PERFORMANCE

Lean production may have a significant public good spillover—improved environmental performance. However, empirical evidence of the link between lean production practices and environmental performance has not resolved the nature of the relationship. To explore this issue, we conduct an empirical analysis of the environmental performance of 17,499 U.S. manufacturing establishments during the time period 1991–1996. We find that those establishments that adopt the quality management standard ISO 9000 are more likely to adopt the environmental management standard ISO 14000. We also find strong evidence that lean production, as measured by ISO 9000 adoption and low chemical inventories, is complementary to waste reduction and pollution reduction.     

COMPUTER INTEGRATION AND CATASTROPHIC PROCESS FAILURE IN FLEXIBLE PRODUCTION: AN EMPIRICAL INVESTIGATION

This paper empirically investigates the effect of advanced manufacturing technology on process stability during flexible production in a process industry. A sample of 61 North American fine paper plants is used to examine the relationship between the level of automation installed for controlling changes between paper grades and the incidence of paper web breaks. These web breaks are catastrophic failures; they require the entire plant to be stopped, reinitialized, and restarted. Because a large fraction of breaks occurs shortly after changeovers, they are an important determinant of the aspect of plant flexibility, called mobility, or the ability to move between products with only small penalties. In an attempt to ensure stable and mobile production, many plants have implemented changeover automation. We find, however, that higher levels of this automation are significantly associated with higher rates of catastrophic failure among the plants studied. We suggest that this finding becomes less paradoxical when considered in light of a recent stream of research on advanced manufacturing technologies, loosely called the usability perspective. According to this perspective, automation designed and implemented with the narrow, technical goal of replacing human operators or removing their discretion over a production process is misguided, especially in environments in which requirements are changing rapidly.
