A new approach to the identification of regional clusters: hierarchical clustering on principal components

This study focuses on the identification of regional business clusters as a primary step in the design and implementation of cluster-based development strategies. A methodology that has not been used previously to identify clusters is applied to data on inter-industry linkages from the input–output table of a region in northern Spain. The first advantage of this approach, hierarchical clustering on principal components (HCPC), over the use of factorial analysis alone, is that it involves the application of objective clustering techniques to the principal components analysis results, which leads to a better cluster solution. A second advantage is derived from using a mixed algorithm for the clustering process – a combination of the Ward’s classification method with the K-means algorithm – which improves the robustness of the final results.     

Public trust and corruption perception: disaster relief

Public trust in government and nongovernment organizations is essential to the public’s willingness to donate and to support those organizations. We measure public trust in disaster aid using people’s perception of these organizations’ effectiveness in delivering aid relief to the victims of two recent major earthquakes in China. Based on the survey data collected in 2013 from about 2100 residents in Hong Kong, we document the vulnerability of these residents’ trust perceptions in aid delivery. We find that the sharp decline in trust perception is highly negatively correlated with their perception of corruption of local governments in China.     

Book and Film Reviews

Economic theory as applied to the family should increase our understanding of the phenomena we are studying, and allow us to implement fruitful intervention in cases where we are not satisfied with what is occurring. Much if not all of the theory of the family fails to achieve these aims. Examples are given from the most recent edition of Gary Becker's Theory of the Family, where the analysis leads to conclusions that are, on their face, preposterous. This kind of theorizing leads, as does almost all neoclassical theory, to a conclusion that the institutions depicted are benign, and that government intervention would be useless at best and probably harmful. But it isn't necessarily so.     

The empowerment expectation–perception gap: An examination of three alternative models

Previous empowerment research has focused on subordinate perceptions of empowering leadership and its outcomes. Met‐expectations theory suggests that subordinate expectations of leader behaviours are essential in forming their a posteriori evaluations. To address the lack of investigation of individual expectations in the empowerment literature, in this study, we explore how subordinates' empowerment expectations and perceptions combine to influence their job satisfaction and psychological empowerment based on three alternative, theoretically derived met‐expectation models, namely, the disconfirmation model, the ideal‐point model, and the experiences‐only model. The results of a 2‐stage study of 114 respondents indicate that employees are more satisfied with their work when perceived empowerment exceeds expectations. However, both empowerment perceptions and expectations positively contribute to higher psychological empowerment. We then discuss implications and directions for future research.     

Augmenting the eye of the beholder: exploring the strategic potential of augmented reality to enhance online service experiences

Driven by the proliferation of augmented reality (AR) technologies, many firms are pursuing a strategy of service augmentation to enhance customers’ online service experiences. Drawing on situated cognition theory, the authors show that AR-based service augmentation enhances customer value perceptions by simultaneously providing simulated physical control and environmental embedding. The resulting authentic situated experience, manifested in a feeling of spatial presence, functions as a mediator and also predicts customer decision comfort. Furthermore, the effect of spatial presence on utilitarian value perceptions is greater for customers who are disposed toward verbal rather than visual information processing, and the positive effect on decision comfort is attenuated by customers’ privacy concerns.     

International trade,technological shocks and spillovers in the labour market: a GVAR analysis of the US manufacturing sector

We empirically analyse the response of labour market related variables in the US manufacturing sector to various shocks, notably to trade openness and technology, as well as examining spillovers from industry-specific labour market shocks. The econometric approach involves an application of the recently developed Global Vector Autoregression methodology of Dées et al. (2007 Helbling, T, Jaumotte, F and Sommer, M. 2006. How has globalization affected inflation?. IMF World Economic Outlook, April: 97–134.  [Google Scholar]) to 12 manufacturing industries over the period 1977–2003. The framework allows us to analyse the response of a standard set of labour-market related variables (employment, real compensation, productivity and capital stock) to exogenous factors (a sector-specific measure of trade openness, a common technology and oil price shock), along with industry spillovers using specific measures of manufacturing-wide variables for each sector. Generalized impulse responses indicate that increased trade openness negatively affects real compensation, has negligible employment effects and leads to higher labour productivity. These impacts, however, are relatively weaker than those induced by technology shocks, with the latter positively and significantly affecting both real compensation and employment. There is also evidence of positive spillovers across industries from sector-specific employment and productivity shocks. Impact elasticities suggest strong intra-sectoral linkages for employment and capital stock formation, contrasting with weak linkages for what concerns real compensation and productivity.     

Institutionalism and New Trade Theory: Rethinking Comparative Advantage and Trade Policy

Gomory and Baumol (2000), and Samuelson (2004) have raised concerns about international trade’s future impact on U.S. national income. The focus is how globalization may affect the size and distribution across countries of gains from trade. Though their analysis is developed using a pure trade theoretical framework, it has strands in common with institutionalist thinking. Their findings spotlight the need for a new U.S. trade policy agenda aimed at maximizing the U.S. share of gains from trade, and complementing conventional Keynesian open economy macroeconomic analysis.     

On the Contributions of Barbara Bergmann to Economics

Abstract

This paper examines the major economic contributions of Barbara R. Bergmann. After presenting her personal background information, it gives an overview of her theoretical framework. This is followed by her critique of economic methodology and an examination of her major contributions in micro-simulation, feminist analysis of labor markets and the family, and policy-oriented work focused on improving the lives of women and children. The essay concludes with a brief discussion of Bergmann's unique qualities as an activist economist in the pursuit of social change.     

Purchasing power parity over two centuries: trends and nonlinearity

In two recent contributions Lothian and Taylor, and Cuddington and Liang, produced empirical evidence that annual data for the dollar-sterling real exchange rate spanning two centuries exhibited a non-linear deterministic trend. This trend could be proxying Harrod-Balassa-Samuelson effects. Lothian and Taylor showed that a linear stationary autoregressive mode, which embodied a cubic trend, implied much faster mean reversion of the real exchange rate to shocks than a model that excluded the trend. This article shows that both non-linearity and a deterministic trend can be allowed for in a theoretically appealing manner and that the fitted models provide a parsimonious explanation of both the dollar-sterling and franc-sterling real exchange rates over the two centuries of data. Generalized impulse response function analysis of the models demonstrates that the speed of adjustment to shocks can be even faster when trends are considered.     

Factors Determining Student Retention of Economic Knowledge after Completing the Principles-of-Microeconomics Course

It is probable that all teachers wonder how much of their instruction stays with the students—and for how long. This question has been examined before, but the authors of this article provide new dimensions and suggest analytical techniques that should be of interest to other economic education researchers. For example, they quantify the rate of depreciation of economic knowledge over time, as well as the “counterdecay effects” of several variables.
