Firm ownership and internal labour practices in a transition economy

One feature common to many post‐socialist transition economies is a relatively compressed wage structure in the state‐owned sector. We conjecture that this compressed wage structure creates weak incentives for work effort and worker skill acquisition and thus presents adverse consequences for the entire transition economy if a substantial portion of the labour force works in the state sector. We explore firm wage incentives and worker training, as well as other labour practices and outcomes, in a transition setting with matched firm and worker data collected in one of the largest provinces of Vietnam – Ho Chi Minh City. The Vietnamese state sector exhibits a compressed wage distribution in relation to privately owned firms with foreign ownership. State wage practices stress tenure over worker productivity and their wage policies result in flatter wage–experience profiles and lower returns to education. The state work force is in greater need of formal training, a need that is in part met through direct government financing. In spite of the opportunities for government financed training and at least partly due to inefficient worker incentives, state firms, by certain measures, exhibit lower levels of labour productivity. The private sector comparison group to state firms for all of these findings is foreign owned firms. The internal labour practices of foreign firms are more consistent with a view of profit‐maximizing firms operating with no political constraints. This is not the case for Vietnamese de novo private firms that exhibit much more idiosyncratic behaviour and whose labour practices are often indistinguishable from state firms. The exact reasons for this remain a topic of on‐going research yet we conjecture that various private sector constraints, including limited access to formal capital, play an important role.     

The curse of natural resources in the transition economies*

The curse of natural resources is a well‐documented phenomenon for developing countries. Economies that are richly endowed with natural resources tend to grow slowly. Among the transition economies of the former ‘Eastern Bloc’, a similar pattern can be observed. This paper shows that a large part of the variation in growth rates among the transition economies can be attributed to the curse of natural resources. After controlling for numerous other factors, there is still a strong negative correlation between natural resource abundance and economic growth. Among the transition economies the prime reasons for the curse of natural resources were corruption and a neglect of basic education. In order to overcome the curse of natural resources and move to a sustainable path of development, the resource abundant transition countries should fight corruption and ensure that their resource revenues are invested in human capital or the preservation of natural capital.     

Leaving state sector employment in Russia

I analyse the reallocation of labour and human capital from the state sector to the non‐state sector and non‐employment in Russia. I use a nationally representative household dataset, the Russian Longitudinal Monitoring Survey, to study sectoral mobility in early transition using summary measures of mobility and multivariate discrete choice models. The results show that sectoral mobility varies between different skill groups, and in particular that those with university education, with supervisory responsibility and in white‐collar occupations are less likely to leave state jobs for both non‐state employment and non‐employment. The results suggest that in the early stages of transition in Russia mismatch of skills across state/non‐state employment was significant and that non‐state employment consisted mostly of low skill, ‘bad’ jobs.     

Squatting as a transition problem in South Africa

This paper applies principles of transition to land tenure and squatting in South Africa. Political transition in South Africa reassigned political property rights, which produced contestable, and rent‐seeking incentives for squatting as a means to privatize land and redistribute wealth. Government failure to establish and protect private property rights in a squatter camp resulted in common‐pool problems that resisted private and public resolution with consequent rent dissipation and social loss. In response to this retreat from duty, informal agents emerged to claim their own share of the prize. Without enforceable rules of capture, the growth of squatter camps in South Africa will continue.

Institutional design and the closure of public facilities in transition economies

As part of the reforms of their systems for financing and delivering health care, many transition economies, particularly in central and eastern Europe, have adopted national insurance funds that are institutionally separate from ministries of health. Most of these countries have also grappled with the problem of restructuring the delivery system, especially the need to reduce hospital capacity. Although improving the performance of medical care providers through a shift from passive budgeting to explicitly incentive mechanisms is important, why this change in financial relations between the government and providers could not be implemented simply by reforming the role of health ministries is not obvious. This paper presents an explicit rationale for the separation of powers between the regulator (the ministry of health) and the financing body (the insurance fund), based on the inability of a single agency to commit to closing hospitals.

Influence analysis for Poisson inverse Gaussian regression models based on the EM algorithm

For Poisson inverse Gaussian regression models, it is very complicated to obtain the influence measures based on the traditional method, because the associated likelihood function involves intractable expressions, such as the modified Bessel function. In this paper, the EM algorithm is employed as a basis to derive diagnostic measures for the models by treating them as a mixed Poisson regression with the weights from the inverse Gaussian distributions. Several diagnostic measures are obtained in both case-deletion model and local influence analysis, based on the conditional expectation of the complete-data log-likelihood function in the EM algorithm. Two numerical examples are given to illustrate the results.     

黄河流域和长江经济带制造业绿色转型效率对比

以黄河流域和长江经济带沿线19个省份为样本,建立超效率SBM(slack-based measure)模型测算分析了2013-2022年黄河流域和长江经济带的制造业绿色转型效率,并利用\"泰尔指数\"进行转型效率的差异性分析.研究发现,长江经济带绿色转型效率呈上升趋势,相反黄河流域发展相对缓慢;通过差异性分析发现黄河流域的域制造业绿色转型效率低于长江经济带,并且黄河流域中各省份的差异性相差较大.     

退耕还林工程对西部农户收入的影响:对西安周至县南部山区乡镇农户的实证分析

研究目的:分析研究退耕还林工程对西部山区农户收入的影响和作用。研究方法:利用西安交通大学人口与发展研究所2008年4月在周至南部山区的农户生计调查数据,建立统计回归模型,分别采用多元线性和分位数回归分析方法,定量分析退耕还林工程对西部山区农户收入的影响。研究结果:参与退耕还林对农户家庭纯收入有着显著的正向影响,尤其是对于中低收入农户,但参与退耕通过户耕地面积和农业劳动时间变化对中低水平的农户收入也仍有一定的负面作用。研究结论:为巩固退耕工程成果,当地政府应提供信息,提高农户的社会资本,积极发展外出务工等非农生产活动。     

山东省马铃薯种植收益影响因素分析

以山东省为例,运用主成分回归分析和灰色关联分析对山东省马铃薯种植收益的影响因素进行分析。结果发现,影响马铃薯种植收益最显著的因素是马铃薯售价,另外,人工成本、种子费用、租赁作业费和化肥费用对马铃薯收益的影响也较大。其中种子费、化肥费、主产品售价、间接成本正向影响马铃薯种植收益,农药费、租赁作业费、人工成本以及土地成本负向影响马铃薯收益。据此,提出降低马铃薯种植成本、提高收益的对策建议。
