SOME ASPECTS OF FOOD CONSUMPTION AND ITS LONG-TERM PERSPECTIVE IN PAKISTAN, 1961-86

This paper attempts to answer three important questions regarding the consumption of food in Pakistan: (2) What are the recent trends of consumption in the rural and urban areas? (2) What is the likely direction and magnitude of food demand during the period 1961-86? (3) Is the growth of production of food commodities going to be sufficient to meet the requirements by 1970 and thereafter?     

Coworking spaces: Understanding,using, and managing sociomateriality

Companies increasingly embrace the new types of work associated with coworking spaces. Coworking spaces started with the idea of a melting pot of open social interaction, collaboration, entrepreneurship, and innovation for freelancers, new ventures, or solo entrepreneurs. Companies may use coworking spaces to invigorate targets and further motivate and inspire their employees. Fundamental to achieving those targets is the coworking space’s interior design and architecture that incorporates emotional and social values that may benefit companies. Our sociomateriality perspective helps to analyze conditions in coworking spaces and guides suggestions on how companies revitalize by using coworking spaces. The purposeful design of the different social and work areas in coworking spaces can improve communication, collaboration, and innovation in companies.     

Centralization of intragroup equity ties and performance of business group affiliates

Research summary : Although prior research has suggested that equity ties are important for business groups, less attention has been paid to the specific mechanisms through which equity ties create value. We develop a framework that specifies how centralization of intragroup equity ties affects the performance of group affiliates. We use the exogenous shock of the 2008 financial crisis and a difference‐in‐differences analysis of 51,730 observations of business group affiliates in Taiwan to show that centralization of equity ties enhances affiliate performance, but such effects weaken when the environment becomes turbulent. Moreover, we find that listed affiliates obtain fewer benefits from centralization than unlisted affiliates. Overall, our study deepens scholarly understanding of not only how groups create value, but also how value is differentially appropriated among affiliates. Managerial summary : Our research speaks directly to owner‐managers of business groups with respect to creating an optimal equity network structure that binds the affiliated firms of the group. Our findings suggest to managers that the overall structure of equity ties in a business group has major implications for the performance of the affiliate firms of the group, and the network structure within the group should be designed deliberately and thoughtfully on an on‐going basis. In particular, control through centralized equity ties is performance‐enhancing in normal periods, but such control may be counterproductive as turbulence increases in business environments, or as the number of listed group firms increases. Hence, owner‐managers may consider optimizing the network structure by lowering the degree of centralized equity ties under such circumstances, or at a minimum, lowering centralized control.

Trend Analysis of Motivation-Based Clusters at the Chilkoot Trail National Historic Site of Canada

This study combines data from three cross-sectional surveys (1993, 1998, and 2004) to explore how hikers at the Chilkoot Trail National Historic Site of Canada were affected by the introduction of several restrictive management policies. The analysis revolves around motivation-based segments defined via one single principal component and cluster analysis over all three years of data. The results document similarities and differences between the three motivation-based segments over time and as a reaction to the restrictions. Clusters also differed in the reaction to indicator variables such as advance booking time, perceived management problems, encounters, and satisfaction. Future longitudinal data collections and investigations as part of visitor monitoring protocols are suggested.     

Measuring Electronic Commerce Technology–Enabled Business Value: An Empirical Investigation

This research investigates whether firms using e-commerce technologies are successful in generating business value and, if so, which e-commerce drivers determine this success and how firms should use these drivers. There is no systematic empirical evidence in the IT productivity and business value literature regarding the payoffs a business receives from its e-business initiatives. The current research contributes to the literature in the e-commerce area by identifying a set of e-business value constructs, incorporating these constructs in a model in a manner not done before, and empirically validating the model using an Analysis of MOment Structures (AMOS)/?Structural Equation Modeling (SEM) analysis. The present research also contributes to the e-business value literature by providing insights into causal relationships among Rogers' innovation and diffusion theory (IDT) factors. This is the first time a research study has empirically established comprehensive causal relationships among these factors. The SEM analysis of the model indicates that the proposed model is able to explain e-commerce success utilizing the constructs identified and grounded using IT business value literature and Rogers' IDT. We conclude by summarizing its contributions to the IT literature, in general, and the e-business literature, in particular, and by providing insights for practice and suggestions for future research.     

Hans Singer's model of the severity of recessions

This paper draws attention to the innovative but neglected workof Hans Singer on the dynamics of unemployment. Influenced byKeynes, in the late 1930s Singer enquired into the relationshipbetween the inflow into unemployment—resulting primarilyfrom (involuntary) separations from employment—and thesize of the resultant fluctuations in the level of unemployment.His focus was on the determinants of the severity—measuredin terms of how far unemployment rises—of recessions.We illustrate his approach by looking at quarterly data forthe claimant count and its associated inflow and outflow inthe UK over the period 1989–2003, a period which includesone major recession episode. In addition to drawing attentionto Singer's ideas, the paper also extends his model by takinginto account recent empirical evidence on the behaviour of oneof the key variables in his model. We argue that, with thisextension, Singer's elegant and parsimonious model of unemploymentdynamics is a useful complement to Keynes's ideas on the fluctuationsin aggregate demand and output, and is of contemporary relevance.     

Iraq’s budgetary practices post US invasion: a critical evaluation

ABSTRACT

Although the steep decline in oil prices has inflicted havoc on Iraq’s public finances, critical analyses of the budgetary decisions and processes post-US invasion have uncovered other factors that have impeded Iraq’s economic progress. The authors evaluate Iraq’s budgets for the period 2003 through 2012 from three perspectives: legislative framework, revenue and expenditure, and monitoring. One of their primary findings is that Iraq has been operating at a surplus in excess of $85 billion. This finding contradicts officials who claim that Iraq has been operating at a large deficit. The authors explain why Iraq’s current budgetary practices of preparing, ratifying, executing and monitoring the country’s federal budget is fundamentally deficient, and much work is needed to reform its public financial management (PFM) system to bring it up to best international practices.     

Where can capabilities come from? network ties and capability acquisition in business groups

While strategy researchers have devoted considerable attention to the role of firm‐specific capabilities in the pursuit of competitive advantage, less attention has been directed at how firms obtain these capabilities from outside their boundaries. In this study, we examine how firms' multiplex network ties in business groups represent one important source of capability acquisition. Our focus allows us to go beyond the traditional focus on network structure and offer a novel contingency model that specifies how different types of network ties (e.g., buyer‐supplier, equity, and director), individually and in complementary combination, will differentially affect the process of R&D capability acquisition. We also offer an original analysis of how other aspects of network structure (i.e., network density) in business groups affect the efficacy of network ties on R&D capability. Empirically, we provide an original contribution to the capabilities literature by utilizing a stochastic frontier estimation to rigorously measure firm capabilities, and we demonstrate the value of this approach using longitudinal data on business groups in emerging economies. We close by discussing the implications of our supportive results for future research on firm capabilities, organizational networks, and business groups.

Introductory honors economics on the Web

Economics 304KH and 304LH at The University of Texas at Austin are introductory honors economics courses. Our goal was to provide students with more advanced material than available in introductory textbooks, such as a discussion of microeconomics based on one‐dimensional calculus and a survey of macroeconomics based on economic models. The supplemental material consists of Web course notes, on‐line quizzes, simulation and data modules and group interactive modules. This paper focuses on the development of Web economic course materials. We discuss the difficulties of programming mathematical instructional material in HTML and the coming solution in XML, JavaScript, and Java. The effectiveness of the on‐line course materials are also evaluated based on student responses. This revised version was published online in June 2006 with corrections to the Cover Date.
