This paper adopts multilevel analysis to study the agglomeration-performance nexus for domestic firms in sub-Saharan Africa. We show that contextual factors can explain up to 30 % of the variance in firms’ productivity, more than half of which depends on the geographic location. Our results show also that African firms’ productivity is positively correlated to the size of the agglomeration when they locate in larger cities specialized in different sectors, while the relation turns negative when they face direct competition from firms in the same industry. These effects are similar in the services and the manufacturing industries, even if in the latter positive spillovers are found to be conditional to the presence of backward and forward linkages with nearby firms. Finally, we are able to show that these effects are also confirmed when domestic firms locate close to foreign multinationals, especially those coming from the South. 相似文献

This paper examines the structural determinants of output volatility in developing countries, and especially the roles of geography and institutions. We investigate the volatility effects of market access, climate variability, the geographic predisposition to trade, and various measures of institutional quality. We find an especially important role for market access: remote countries are more likely to have undiversified exports and to experience greater volatility in output growth. Our results are based on Bayesian methods that allow us to address formally the problem of model uncertainty and to examine robustness across a wide range of specifications. 相似文献

Abstract Accident risk analysis for human safety and infrastructural improvement are key requirements of the engineering sector. The purpose of this paper is to identify and prioritize problematic segments of roads based upon the risk evaluation concept and to focus on the severity of accidents regarding human life loss and easy manoeuvring. This study includes the concept of considering road segments as decision-making units for application of data envelopment analysis (DEA) technique which has no compulsion of the distribution function and critical assumptions, unlike the multiple regression models. According to the proposed methodology, a section of Motorway (M-2) Lahore-Islamabad has been analyzed. Out of 200 segments under consideration, 99 segments were selected with at least one accident and one injury or fatality. Furthermore, for risk calculation and ranking of road segments, the DEA technique along with the cross-risk matrix method was applied. This optimization technique could not only be helpful in ranking but also technical decision-making and prioritizations for safety improvement, policymaking and budget allocation. 相似文献

This paper analyses cost and profit efficiencies in commercial banking in the eight Central and Eastern European countries that became new members to the European Union. Common stochastic cost and profit frontiers with country-specific variables are employed in order to take into account macro-economic and financial sector conditions that vary over time and across countries. The impact of foreign ownership on performance is also examined. The results indicate a wide range of cost and profit inefficiency scores across countries and across different size groups. All banking systems in the sample display significant levels of cost and profit inefficiency and there does not seem to be any continuous improvement in performance over time. There is also some evidence that foreign banks perform, on average, better than domestic banks. 相似文献

According to the US EIA (2009, www.eia.doe.gov), out of the 15 largest oil producing nations in the world, 7 are not OPEC members, namely Brazil, Canada, China, Mexico, Norway, the Russian Federation, and the United States of America (USA). This paper investigates the causal relationship between energy consumption and economic growth for these non-OPEC oil producing countries. Real GDP per capita is used to measure economic growth; whereas; energy consumption is represented by four sub-variables (electric power, oil, natural gas, and coal energy). Using a panel data covering (1969–2009), this study employs the Pedroni (Econometric Theory, 20, 597–627, 2004) approach to determine cointegration and the (Econometrica, 55, 251–276, 1987) two-step procedure to explore short and long run causal effects. The results suggest that there are long run relationships between the real GDP, labour force, real capital, oil consumption, electricity consumption, gas consumption and coal consumption. Further analyses show that real GDP and oil consumption Granger cause real gross capital formation in the short run; real gross fixed capital and electricity consumption cause oil consumption in the short run; and also oil consumption and gas consumption cause electricity consumption in the short run. 相似文献

In this study, we explore the relationship between inclusive leadership and change‐oriented organizational citizenship behaviour (OCB) with the mediating roles of behavioural integrity and trust in leadership. Data were collected from 151 supervisor–subordinate dyads from small and medium enterprises in Pakistan. The results revealed that inclusive leadership is positively related to change‐oriented OCB. Our study reaffirms the indirect effect of the inclusive leadership on change‐oriented OCB via behavioural integrity and trust in leadership. Finally, the results supported the chain of causality: sequential mediation of behavioural integrity, and trust in leadership between inclusive leadership and change‐oriented OCB. Causal attribution theory is used to support the findings. Implications for theory and practice are discussed. 相似文献
