Poverty in South Africa: Statistical inference for decomposable poverty measures

The measurement of poverty involves two problems: identifying the poor and constructing an index to measure the intensity of poverty. The headcount ratio is one of the widely used indices for the measurement of poverty. This article considers some of the other decomposable (i.e. additively separable) poverty measures. The importance of this property (decomposability) and of subgroup consistency for a poverty measure is highlighted. Since most of these poverty measures are estimated on the basis of sample surveys, the statistical significance of the observed differences is tested using the distribution-free approach proposed by Kakwani (1993, Review of Economics and Statistics , 75: 632-40). The Income and Expenditure Survey conducted in 1995 by Statistics South Africa, then called Central Statistical Service, is used in the study.     

Entrepreneurship and Start-Ups in the Boston Region: Factors Differentiating High-Growth Ventures from Micro-Ventures

The use of entrepreneurship to stimulate economic growth in lagging regions of the world has grown over the last decade. The type of business needed for job creation is a new venture rather than a micro-business. The experience of a major program in the U.S., empowerment zones, has failed to produce many jobs, mostly because the program has stimulated micro-businesses rather than growth ventures. This paper analyzed the factors differentiating between the formation of high-growth ventures and micro businesses, and discussed how these factors may best influence the activities of organizations that either nurture ventures or create government policies for regional development. The data consisted of ninety business plans submitted to a business plan competition in Boston. The results showed that founders of high-growth ventures have work experience or advanced training in their technologies, and teams rather than individuals created the plans. The results suggest that a combination of exogenous and endogenous approaches may be needed to stimulate a lagging region's economic growth.     

Schumpeterian competition in heterogeneous oligopolies

The modeling of Schumpeterian competition as a process of innovation, imitation and selection was first presented by Nelson/Winter (1982) in a simulation study and further analyzed in a similar but general analytical formulation by Iwai (1984a, 1984b). Their results concerning the relations between the combination of the different forces of Schumpeterian competition and market structure respectively the distributions of profits are interesting, but restricted to competitive markets. Comparing rules of thumb and satisficing for the Ramp;D decisions the present study analyzes the process of Schumpeterian competition in a heterogeneous oligopoly. Firstly, the authors find for the Ramp;D-concentration relation results contrary to the traditional interpretation of Schumpeter. Secondly, Iwai’s (1984a, 1984b) qualitative results hold in this less restrictive modeling.     

PERSPECTIVE: How Honda Innovates*

This article describes how Honda leverages its engine and other key subsystem technologies into new products uniquely designed for new target users and their new special uses. In this profile of the development of the Honda Element sports utility vehicle, we see how firm can identify new target applications, dive deeply into user research, and translate its acquired insights into specific designs and features. The feasibility and profitability of the effort is maximized by leveraging robust, fully operational platforms within new product lines.     

Dynamic Influences on Individual Choice Behavior

Research examining the process of individual decision making over time isbriefly reviewed. We focus on two major areas of work in choice dynamics:research that has examined how current choices are influenced by the historyof previous choices, and newer work examining how choices may be made toexploit expectations about options available in the future. A central themeof the survey is that if a general understanding of choice dynamics is toemerge, it will come through the development of boundedly-rational models ofdynamic problem solving that lie on the interface between economics andpsychology.     

Trade Policy Transparency and Investor Confidence: Some Implications for an Effective Trade Policy Review Mechanism

This paper is concerned with the value of the WTO's Trade Policy Review Mechanism, particularly its transparency role and its potential role in policy stability, for investor confidence in developing countries. The implications of reduced risk and uncertainty regarding trade policy for investor confidence, and ultimately for the capital stock and the long-run structure of production, are examined in an analytical model. Certainty equivalence is employed to assess the general equilibrium effects of risk and uncertainty. Their reduction can boost risk-adjusted returns, leading to an increase in long-run levels of capital.     

Globalfocusing: From Domestic Conglomerates to Global Specialists*

abstract Globalization is changing the competitive terrain on which companies develop their corporate strategy. On the global stage, key competitive advantages are gained through internationally fungible resources. Consequently, diversified conglomerates are converting to global specialists in narrower niche markets and competing with a small number of multinational enterprises operating worldwide. Their internationalization and their reduction of product diversification are opposite sides of the same coin: globalfocusing. I extend Penrosian resource‐based theory to analyse this change process, notably by distinguishing country and industry specificity of firms' core competences, and by integrating divestment as part of firm growth processes. Globalfocusing is driven by shifts in the relative importance of country‐specific and industry‐specific resources and capabilities due to changes in the internal and external environment, notably the globalization of markets and supply chains. The argument is developed using case studies of restructuring of two Danish manufacturing enterprises. On this basis, I analyse the forces driving globalfocusing processes and suggest propositions for empirical testing.
