Since their initial development, railroads have always beencentral to the development of Chicago as the transportationhub of the Midwest and the nation. Indeed, they remain centralin the twenty-first century. Although the number of trains andtrackage declined precipitously as consolidations and deregulationtook hold in the twentieth century, the actual tonnage hauledand the number of trains have grown. Consequently, Chicago founditself "as inundated with railroad trains in 2001 as it hadbeen a century earlier" (p. 220). Young     

Service-for-equity arrangements: Untangling motives and conflicts

Many professional service organizations have adopted a little understood contractual form: service-for-equity. Based on in-depth case studies of 12 major professional service providers with a combined experience of 179 equity-for-service deals, this paper documents 18 intended and unintended consequences, emanating from and expanding beyond agency theory, of adopting such a contractual form. Six propositions are developed which speculate how these consequences, categorized under client development, service operations, financial management, and organizational behaviour, affect long run performance. Assuming these propositions cannot be rejected through empirical analysis, the paper also provides managerial guidance for effective implementation of equity-for-service arrangements.     

Learning to export: Export growth and the destination decision of firms

I find evidence that the geographic expansion of firm exports occurs slowly over time and that a large share of export growth is due to incumbent exporters entering new destinations. New exporters enter large countries and destinations with characteristics similar to their domestic market. Less similar, distant or less developed countries are entered by firms already exporting to other destinations. I formulate a dynamic general equilibrium model to test if these patterns are due to firms learning how to export (as other recent empirical findings have suggested) or other factors considered in the literature. In this model, heterogeneous firms experience learning in the form of market entry costs that depend on export history. Using Russian firm level data, I find that learning plays a significant role in explaining the observed entry patterns, which standard trade models cannot account for.     

Application and Assessment of an Ethics Presentation for Accounting and Business Classes

This paper describes a presentation on ethics for accounting and business students. In 2001 and 2002, major corporate failures such as Enron and Worldcom, combined with questionable accounting practices, made ethics a paramount concern to persons working in business and accounting. While financial statement analysis and regulatory requirements are important technical topics, the issue of ethics provides faculty a unique and very appropriate setting to discuss deeper truths about doing business and living life well. This paper briefly describes the development and assessment of one approach to presenting ethics built around a computerized slide show (PowerPoint). The goal of the presentation is to increase students’ understanding of the essential role of ethics to accounting and business. Following the presentation, students indicated a heightened recognition of the importance of ethics. Educators should do all that they can to encourage students to do the “right” thing, even in difficult circumstances. This encouragement may serve them well in school and later in their careers.     

Eisenhardt's impact on theory in case study research

This article summarizes the key points of Eisenhardt's (1989), “Building theories from case study research,” and its impact on research in management and marketing. The present article uses citation data from the Web of Knowledge database which shows that Eisenhardt (1989) has 2509 citations to the end of 2008, and that the articles first citing Eisenhardt (1989), most frequently citing Eisenhardt (1989), and most recently citing Eisenhardt (1989) appear in high-ranking journals. The citation impact for Eisenhardt (1989) far exceeds that of other articles appearing in the same issue of the Academy of Management Review. Eisenhardt (1989) continues to receive high numbers of citations annually. The use of citations indicates an increasing engagement with Eisenhardt's (1989) framework, and an influence across several business disciplines. In a comparison with Armstrong's (2003) measure of important findings, this present study concludes that Eisenhardt's (1989) article is important in terms of the replication, validity, usefulness, and surprise values of her findings.     

Comparing supply‐side specifications in models of global agriculture and the food system

This article compares the theoretical and functional specification of production in partial equilibrium (PE) and computable general equilibrium (CGE) models of the global agricultural and food system included in the AgMIP model comparison study. The two model families differ in their scope—partial versus economy‐wide—and in how they represent technology and the behavior of supply and demand in markets. The CGE models are “deep” structural models in that they explicitly solve the maximization problem of consumers and producers, assuming utility maximization and profit maximization with production/cost functions that include all factor inputs. The PE models divide into two groups on the supply side: (1) “shallow” structural models, which essentially specify area/yield supply functions with no explicit maximization behavior, and (2) “deep” structural models that provide a detailed activity‐analysis specification of technology and explicit optimizing behavior by producers. While the models vary in their specifications of technology, both within and between the PE and CGE families, we consider two stylized theoretical models to compare the behavior of crop yields and supply functions in CGE models with their behavior in shallow structural PE models. We find that the theoretical responsiveness of supply to changes in prices can be similar, depending on parameter choices that define the behavior of implicit supply functions over the domain of applicability defined by the common scenarios used in the AgMIP comparisons. In practice, however, the applied models are more complex and differ in their empirical sensitivity to variations in specification—comparability of results given parameter choices is an empirical question. To illustrate the issues, sensitivity analysis is done with one global CGE model, MAGNET, to indicate how the results vary with different specification of technical change, and how they compare with the results from PE models.     

How do female entrepreneurs perform? Evidence from three developing regions

Using the World Bank Enterprise Survey data, we analyze performance gaps between male- and female-owned companies in three regions—Eastern Europe and Central Asia (ECA), Latin America (LA), and Sub-Saharan Africa (SSA). Among our findings are significant gender gaps between male- and female-owned companies in terms of firm size, but much smaller gaps in terms of firm efficiency and growth (except in LA). Part of the reason women run smaller firms is that they tend to concentrate in sectors in which firms are smaller and less efficient (in ECA and SSA). By contrast, we find no evidence of gender discrimination in access to formal finance in any of the three regions, although in ECA women are less likely than men to seek formal finance. Finally, while female entrepreneurs receive smaller loans than their male counterparts, the returns from each dollar they receive is no lower in terms of overall sales revenue.
