Environmental efficiency and its distribution dynamics in Chinese cities

ABSTRACT

This paper investigates environmental efficiency and its distribution dynamics in Chinese cities. The analyses are applied the meta-frontier data envelopment analysis and the continuous dynamic distribution approach together with panel data of 286 Chinese cities at the prefecture and above-prefecture levels. The results show that during the period of 2002–2011, the average environmental efficiency in Chinese cities is well below the production frontier. The coastal cities show better performance than the central and western cities; large and extra-large cities are more efficient than small and medium cities; and the environmental efficiency for the ‘key’ cities is slightly better than that for the ‘non-key’ cities. The spatial dynamic distribution analyses indicate that the environmental efficiency of Chinese cities tends to converge. To improve environmental efficiency in the future, the government should pay more attention to the central cities, medium and large size cities in western China, and the non-key cities.

Towards a better measure of income inequality in Indonesia

Indonesia has experienced significant economic growth in recent years (on average, 5% in 2000–08), but many people are still living in poverty. Income inequality, as measured by the official Gini coefficient, has also increased. This paper evaluates household income and income inequality in Indonesia, assessing both market and non-market income to reach a more accurate measure of how actual income affects living standards. We find that if household income considers non-market income, income distribution is significantly more balanced, the coefficient of income inequality falls from 0.41 to 0.21 and the income share of the population's poorest deciles increases more than fivefold. The results suggest that market income alone is a misleading measure of income distribution in Indonesia.     

Do oil tariffs lower wages?

An oil tariff has potential to alter the pattern of production and income distribution across productive factors. This paper use a general equilibrium model of production and trade with inputs of capital, labor, and international energy to examine the effects of an oil tariff. Under a range of conditions, higher energy prices created by oil tariffs would lower the ratio of wages to capital rents, and production of labor intensive goods would fall. This paper concentrates on the potential of oil tariffs to alter patterns of production and income distribution.     

Modelling of repairable systems with various degrees of repair

The availability of a stochastic repairable system depends on the failure behaviour and on repair strategies. In this paper, we deal with a general repair model for a system using auxiliary counting processes and corresponding intensities which include various degrees of repair (between minimal repair and perfect repair). For determining the model parameters we need estimators depending on failure times and repair times: maximum likelihood (ML) estimator and Bayes estimators are considered. Special results are obtained by the use of Weibull-type intensities and random observation times.     

A practical road map for assessing cyber risk

The increase in interconnectivity and developments in technology have caused cyber security to become a universal concern. This paper highlights the dangers of the evolution of cyber risk, the challenges of quantifying the impact of cyber-attacks and the feasibility of the traditional actuarial methodologies for quantifying cyber losses. In this paper, we present a practical roadmap for assessing cyber risk, a roadmap that emphasizes the importance of developing a company and culture-specific risk and resilience model. We develop a structure for a Bayesian network to model the financial loss as a function of the key drivers of risk and resilience. We use qualitative scorecard assessment to determine the level of cyber risk exposure and evaluate the effectiveness of resilience efforts in the organization. We highlight the importance of capitalizing on the knowledge of experts within the organization and discuss methods for aggregating multiple assessments. From an enterprise risk management perspective, impact on value should be the primary concern of managers. This paper uses a value-centric/reputational approach to risk management rather than a regulatory/capital-centric approach to risk.
