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?     

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.

Is there a poverty trap for developing countries? Polarization: Reality or myth

A general view that as between countries ‘the rich are getting richer while the poor are getting poorer’ supported in the development literature by explanations relating to cumulative causation, economies of scale etc., and statistically based on the relation between GNP per capita in 1978 and its growth rates during 1960–1978, is shown to contain considerable elements of ‘myth’ or statistical ‘delusion’. The ‘naïve’ polarization hypothesis based on income levels at the end of the period over which growth rates are measured is left with a much weakened empirical basis when the proper substitution of levels of income at the beginning of the period is made. This is particularly so for low- and middle-income countries taken separately, while for the 18 industrialized countries a strong tendency towards convergence in per capita incomes emerges. Finally, for the growth in manufacturing value added during 1960–1977 a significant tendency towards convergence was observed in the case of a group of 24 least developed countries.     

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.     

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.     

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.     

A multilevel government model of deficits and inflation

In this paper, an attempt is made to properly identify the link between deficits and the rate of inflation by using two alternate macroeconomic models—one based on adaptive expectations and the other on rational expectations—for a multilevel government system. It is assumed that unlike federal deficits, state deficits cannot be monetized. Nonetheless, the interaction between state and federal inflation is explicitly incorporated into the model. When expectations are formed adaptively, the model confirms the positive link between deficits and rate of inflation. However, with rational expectations, the model shows that inflation is, in part, explained by the forecast error. It is proposed that only empirical testing of the theoretical models would give credence to such conclusions.
