On the suitability of income inequality measures for regional analysis: Some evidence from simulation analysis and bootstrapping tests

The paper looks at the sensitivity of commonly used income inequality measures to changes in the ranking, size and number of regions into which a country is divided. During the analysis, several test distributions of populations and incomes are compared with a ‘reference’ distribution, characterized by an even distribution of population across regional subdivisions. Random permutation tests are also run to determine whether inequality measures commonly used in regional analysis produce meaningful estimates when applied to regions of different population size. The results show that only the population weighted coefficient of variation (Williamson’s index) and population-weighted Gini coefficient may be considered sufficiently reliable inequality measures, when applied to countries with a small number of regions and with varying population sizes.     

The impact of liberalization on the scope of efficiency improvement in electricity-generating portfolios for the United States and Switzerland

In this study, Markowitz mean-variance portfolio theory is applied to electricity-generating technologies of the United States and Switzerland. Both an investor (focused on changes in return) and a current user (focused on return in levels) view are adopted to determine efficient frontiers of electricity generation technologies in terms of expected return and risk as of 2003. Since shocks in generation costs per kWh (the inverse of returns) are correlated, Seemingly Unrelated Regression Estimation (SURE) is used to filter out the systematic components of the covariance matrix. Results suggest that risk-averse investors and risk-neutral current users in the United States are considerably closer to their efficiency frontier than their Swiss counterparts. This may be due to earlier and more thorough deregulation of electricity markets in the United States.     

Knowledge structures of prospectors,analyzers, and defenders: content,structure, stability,and performance

The managerial cognition perspective argues that managers operating in complex, dynamic environments develop knowledge structures that help them focus their attention, interpretation, and actions. We explore the content and structure of top managers' strategic knowledge structures by measuring differences in the level of attention they give in annual reports to strategic issues and themes that Miles and Snow used to describe their main strategic types. Twenty-one themes that form seven main factors describing managers' strategic cognition are identified, and these demonstrate reasonable fit with the Miles and Snow model. We show that expert raters can recognize these factors when they read annual reports that contain them. Cluster analysis is then used to identify groups of firms that share similar profiles on these strategic dimensions which are interpreted as examples of cognitive strategic groups. These groups show alignment with Miles and Snow's strategic types, are relatively stable over time, and differ in financial performance. The sample comprises 1,038 listed Australian firms between the years 1992 and 2003. Copyright © 2007 John Wiley & Sons, Ltd.     

An examination of the relationships among market orientation,innovation resources,reputational resources,and company performance in the transitional economy of Slovenia

We investigated relationships among market orientation, innovation and reputational resources, and their impact on market performance and financial performance within the transitional economy of Slovenia. Market orientation related positively to market and financial performance of firms indirectly through innovation and reputational resources. Reputational resources associated positively with loyalty, market share, and sales volume, innovation resources associated positively with market share, and sales volume indirectly through customer loyalty. Selected marketing resources related positively to financial performance indirectly through customer loyalty, market share, and sales volume. The implications of these findings for theory and practice are considered. Copyright © 2007 ASAC. Published by John Wiley & Sons, Ltd.     

EMU and the transmission of monetary policy: evidence from business lending rates

This paper analyses the pass-through of money market rates to short-term and long-term business lending rates in the four largest euro area countries. The main findings of the paper are (1) that since the start of EMU loan rates appear to have become more responsive to money market rate changes in France, Italy and Spain, but not in Germany, and (2) that German loan rates are significantly more sluggish than loan rates in the other three large euro area countries. I also test for non-linear pass-through based on an asymmetric error-correction model but do not find much evidence of non-linearity in euro area interest rate pass-through.The views expressed in this paper do not necessarily represent the views of the Deutsche Bundesbank.     

ECONOMIC FREEDOM & HAPPINESS INEQUALITY: FRIENDS OR FOES?

This article examines the relationship between economic freedom and happiness inequality for a large sample of countries. We find that economic freedom is negatively associated with happiness inequality and robust to several alternative measures of happiness inequality, including the standard deviation, mean absolute difference, coefficient of variation, and Gini coefficient. Among the economic freedom areas, legal system and sound money are negatively correlated with happiness inequality. Drawing on the Engerman‐Sokoloff hypothesis, we use a measure of factor endowments as an instrument for economic freedom to provide a further robustness test, finding a negative association between economic freedom and happiness inequality.

A Study of the Performativity of the “Ambidextrous Organizations” Theory: Neither Lost in nor Lost before Translation

Ambidextrous organizations succeed both in incremental and discontinuous innovation. However, there is little direct empirical evidence on how managers implement the principles of the “ambidextrous organizations” theory to dynamically align the structure and culture of ambidextrous organizations. Our study does not focus on analyzing the factors that give rise to organizational ambidexterity but focuses on analyzing whether the factors suggested by prior theorizing on “ambidextrous organizations” are implemented by managers in their daily practice as suggested by prior theorizing. Accordingly, this study does not investigate the traditionally conceptualized gap between academic theorizing and managerial practice since “ambidextrous organizations” theory can be characterized as rigorous and relevant. We investigate whether the “ambidextrous organizations” theory is implemented as suggested by prior theorizing and whether successful implementation is subject to managing in the way that scholars' prior theorizing suggests. Based on qualitative and quantitative data from two longitudinal case studies, we find that managers overlooked the process dimension in evaluating the required degree of ambidexterity. Furthermore, the organizational structure and culture for incremental innovation did not differ from the structure and culture for discontinuous innovation alongside the expected dimensions. Finally, the discontinuous innovation business unit had to be reintegrated to ensure sustained growth. During the reintegration processes, organizational capabilities mutated. We linked our findings on the processes and performativity of ambidextrous organizing to extant theories and developed the rationale for the observed novel phenomena of innovation myopia, second‐order competency traps, and capability mutations.     

Quality and quantity in primary care mixed‐payment models: evidence from family health organizations in Ontario

Abstract We study the impact of a mixed capitation model (the Family Health Organization, FHO) on quality and quantity outcomes among primary care physicians in Ontario. Using a panel of administrative data covering one year before and two years after the FHO model was introduced, we find that physicians in the FHO model provide about 6% to 7% fewer services and visits per day, but are between 7% and 11% more likely to achieve preventive care quality targets. These results suggest that the mixed capitation model with contractible quality indicators may be welfare improving relative to the FFS model.     

How to Achieve the Take-off into Sustained Growth: A Case Study for Slovenia

In this paper, we show that successful policy aimed at enhancing economic growth in the long run must be based on policies which improve human capital and technological progress. This is applied to Slovenia, a small open economy in the European Union and the Euro Area. In particular, we investigate how fiscal policies should be designed to support economic growth without violating the European Union Stability and Growth Pact. Using the SLOPOL10 model, an econometric model of the Slovenian economy, we analyse the effects of different fiscal policies in Slovenia over the next few years by means of simulations. The fiscal policy multipliers of the Slovenian economy are small and short-lived, which renders demand-side expansionary fiscal policies inappropriate as a means of achieving higher growth. However, if an increase in government expenditures directly related to technological progress is implemented (such as better funding for tertiary education or subsidies for firms’ investments in research and development), this can trigger a path of output which is permanently higher than that of the baseline simulation. Reducing income taxes and social security contributions has strong positive effects on employment. This result shows that the key to prosperity and sustained growth is investment in human capital and technology, also for a small open economy like Slovenia.
