Productivity growth of the cities of Jiangsu province,China: a Kaldorian approach

This paper considers the determinants of economic growth of the cities of Jiangsu province, China, adopting a Kaldorian approach. It is found that there is a close correlation between the growth of non-industry and industry (Kaldor’s first law) that provides indirect evidence for the export-base theory. The paper discusses two competing explanations of the foundations of the Verdoorn law (Kaldor’s second law), which, in its simplest form, is the relationship between industrial productivity and output growth. It also considers the static–dynamic Verdoorn law paradox. This arises from the fact that estimating the Verdoorn law in log-levels often gives statistically insignificant estimates of the Verdoorn coefficient while the use of growth rates gives significant values of around one half. The results show that this does not occur when data for the cities are used. A plausible explanation for the paradox is that it results from spatial aggregation bias. It is also found that inter-province urban productivity disparities first increase, but subsequently decrease over the period considered.     

On the time-varying nature of the debt-growth nexus: evidence from the euro area

This article uses the DCC-generalized autoregressive conditional heteroskedasticity model to investigate the existence of time-varying correlations between public debt and economic growth. To that end, we use annual data from both central and peripheral countries of the euro area for the period 1961–2015. The results suggest that the relationships between these variables are time-varying and that in some countries and for some periods, there is a positive association between them.     

The strategic value of CEO external directorate networks: implications for CEO compensation

This study examines the relationship between CEO external directorate networks and CEO compensation. Drawing on previous research showing a link between executives' external networks, firm strategy, and performance, the study argues that executive external networks are strategically valuable to firms; thus, they should be reflected in executive compensation. The study further examines whether firm diversification, with its elevated demand for strategic resources, moderates the relationship between CEO external directorate networks and pay. Hypotheses are tested using a sample of 460 Fortune 1000 firms. Analyses reveal that the rewards to CEO external directorate networks are contingent upon the firm's level of diversification. Implications for future research and practice are discussed. Copyright © 2001 John Wiley & Sons, Ltd.     

INEQUALITY OF OPPORTUNITY IN BRAZIL

This paper proposes a measure of the contribution of unequal opportunities to earnings inequality. Drawing on the distinction between "circumstance" and "effort" variables in John Roemer's work on equality of opportunity, we associate inequality of opportunities with five observed circumstances which lie beyond the control of the individual—father's and mother's education; father's occupation; race; and region of birth. The paper provides a range of estimates of the importance of these opportunity-forming circumstances in accounting for earnings inequality in one of the world's most unequal countries. We also decompose the effect of opportunities into a direct effect on earnings and an indirect component, which works through the "effort" variables. The decomposition is applied to the distribution of male earnings in urban Brazil, in 1996. The five observed circumstances are found to account for between 10 and 37 percent of the Theil index, depending on cohort and allowing for the possibility of biased coefficient estimates due to unobserved correlates. On average, 60 percent of this impact operates through the direct effect on earnings. Parental education is the most important circumstance affecting earnings, but the occupation of the father and race also play a role.     

Do liquidity and idiosyncratic risk matter? Evidence from the European mutual fund market

This paper examines the interaction of idiosyncratic risk, liquidity and return across time in determining fund performance, as well as across investment style portfolios of European mutual funds. This study utilizes a unique data set including returns for equity mutual funds registered in six European countries. Overall, using monthly data, we find that both liquidity and idiosyncratic risk are relevant in determining mutual fund returns. Our results are robust across different model specifications. We show that model specifications up to six factors are useful as these risk factors capture different aspects in the cross-section of mutual funds returns. The evidence regarding mutual funds subgroups is strongly in favor of the significance of liquidity, and idiosyncratic risk to a lesser extent, as risk factors. Even if liquidity and idiosyncratic risk are considered at the same time, one factor is not significantly decreasing the importance of the other factor.     

Definition of innovation projects in small firms: A Spanish study

Small and medium‐sized enterprises (SMEs) are the main holders of the European economy and innovation projects are essential tools for SMEs to ensure their growth. A high percentage of innovation projects implemented by SMEs lacks planning and initial management, which causes the appearance of important problems for the SMEs survival. The authors have confirmed with a field study of 72 Spanish small firms that a lot of these problems arise from an incomplete project definition, so it is necessary to help SMEs to have a specific methodology that is appropriate to their own characteristics and projects. The statistical analysis shows how the project management knowledge helps to a better project definition, contributing to the project alignment with the company strategy. Also, it reveals other problems related to the project definition as planning, budget, market and financing. Of this analysis, it concludes that the definition phase supports the other phases and is essential in order to achieve project success. This paper presents an ‘integration model of factors’ that helps SMEs in the management of the definition phase of their innovation projects. This model relates the various areas of analysis needed to ensure their integration at the project definition. The relationships between the different model areas have been defined, showing the way to integrate the technical, economic and strategic outlooks of project objectives management in the definition phase of the project. This model has been implemented in 21 new innovation project definitions. The users' valuation has been very positive with a 90.4% of success and all of the model users are interested in implementing the model again in next projects. The main advantages highlighted were user‐friendliness, intuitive model and easy application.     

Statistics for the contact process

A d -dimensional contact process is a simplified model for the spread of an infection on the lattice Z ^d . At any given time t ≥ 0 , certain sites x ∈ Z ^d are infected while the remaining once are healthy. Infected sites recover at constant rate 1, while healthy sites are infected at a rate proportional to the number of infected neighboring sites. The model is parametrized by the proportionality constant λ. If λ is sufficiently small, infection dies out (subcritical process), whereas if λ is sufficiently large infection tends to be permanent (supercritical process).
In this paper we study the estimation problem for the parameter λ of the supercritical contact process starting with a single infected site at the origin. Based on an observation of this process at a single time t , we obtain an estimator for the parameter λ which is consistent and asymptotically normal as t →∞     

Examining an Alcohol consumption Kuznets Curve for developed countries

In this paper we expand the Simon Kuznets´ (1955) hypothesis to an ‘Alcohol consumption Kuznets curve’, showing that as income rise, further resources become available to buy more alcohol. Hence, people consume more alcohol and alcohol consumption rates increase. Nevertheless, as income rises, individual health becomes a more recognized point of interest and people decrease their alcohol consumption levels in order to increase their health status. For a selection of OECD countries, we find empirical evidence that alcohol consumption is influenced by income, inequality, unemployment rates, life expectancy and therefore the business cycle. Moreover, the demographic structure (ageing and youth ratio) does not affect the alcohol consumption level.     

The salience of ‘culture’s consequences’: the effects of cultural values on top executive commitment to the status quo

While top executives are argued to play a central role in strategic adaptation, evidence suggests that they are not equally open to organizational change. This study extends earlier investigation of the determinants of top executive commitment to the status quo (CSQ) to the international arena, examining the influence of cultural values on executive open-mindedness toward change. Using data from a survey of top managers in 20 countries, analyses reveal that values of individualism, uncertainty avoidance, power distance, and long-term orientation are significantly related to executives’ adherence to existing strategy and leadership profiles. Further, while confirming earlier findings that industry tenure is positively related to strategy CSQ, results show that tenure does not significantly affect leadership CSQ once cultural values are controlled. In summary, the findings reveal that culture has an important impact on executive mindsets, as demonstrated by the fact that executives of differing cultural background are not equally open to change in organizational strategy and leadership profiles. Second, the findings suggest that executives’ views of appropriate leadership profiles reflect the imprint of cultural socialization moreso than professional experience. Finally, and more broadly, the study offers empirical support for the view that values figure prominently in shaping executives’ strategic and leadership orientations. © 1997 by John Wiley & Sons, Ltd     

Urban food markets and their sustainability: the compatibility of traditional and tourist uses

The aim of this article is to highlight the importance of urban food markets as tourist icons in the current competitive race to create attractive cities. Food markets attract a large number of consumers, both local and tourists. However, their impact on the city and its dynamics should be treated to establish measures to ensure sustainable (compatible) uses for both kinds of users. This calls for the establishment of a system of indicators to determine what level of sustainability food markets are at and facilitate decision-making for the agents involved in their management.
