国有企业民营化的均衡模型

本文是来自于中国近年来实行民营化改制实践的一个理论结晶。该研究在中国特定的渐进改革基础上 ,讨论了民营化发生的原因和阻力 ,以及国有企业的利益相关者在改制过程中的利益权衡行为 ,并根据它们的相互关系和目标行为建立了民营化的均衡模型。模型的核心是企业家的最优目标函数 ,这是关系到企业能否实现成功改制的关键。模型的约束条件反映了利益相关者的基本利益保障 ,不会由于改制而受到损害。因此 ,均衡条件的满足表明了最优化改制的实现。通过对模型的分析发现 ,能够满足民营化最优均衡的退出条件 ,就是国有企业退出的最佳时机选择。企业净资本价值、企业家对股权的收购值与职工补偿值之间的合理比例的区间 ,是形成民营化均衡模型的最优解的取值范围。模型的政策含义在于纠偏作用 ,尤其是政府实际的退出时机与改制均衡的最佳退出时机的不一致 ,对于职工利益的损害或缺乏企业家最优目标行为的改制 ,都是脱离了最优轨道的结果 ,需要进行纠正     

消费波动小于产出波动吗?

我们发现东亚主要经济体普遍存在消费波动大于产出波动的现象,初步分析表明这与各经济体的经济转型有关,我国转型期以来比较剧烈的总消费波动应主要归于居民消费行为的转型:(1)以1990年为界,我国居民总消费自经济转型以来的前一个时间段中波动比较剧烈,之后则趋于平稳。进一步地,由于我国的经济改革先从农村开始,而后推进到城镇,相应地农村和城镇居民消费在两个时间段中的波动幅度也出现了明显差异;(2)消费的剧烈波动往往出现在转型早期,在转型后期大部分东亚经济体的消费序列开始变得平稳;(3)耐用品不能解释我国消费的大部分波动性。     

转型时期弱势群体的社会救助

在社会保障制度的建立和发展过程中,社会救助最早建立.但是,现代的社会救助与早期的社会救助有本质上的区别.转型时期弱势群体的社会救助,是建立在一定的法规之上,具有社会性、制度性和强制性的社会保障制度.     

The determinants of foreign direct investment into European transition economies

Using a panel dataset of bilateral flows of foreign direct investment (FDI), we study the determinants of FDI from Western countries, mainly in the European Union (EU), to Central and Eastern European ones. We find the most important influences to be unit labor costs, gravity factors, market size, and proximity. Interestingly, host country risk proves not to be a significant determinant. Our empirical work also indicates that announcements about EU Accession proposals have an impact on FDI for the future member countries. Journal of Comparative Economics 32 (4) (2004) 775–787.     

Processes and patterns in transitions and system innovations: Refining the co-evolutionary multi-level perspective

This article investigates transitions at the level of societal functions (e.g., transport, communication, housing). Societal functions are fulfilled by sociotechnical systems, which consist of a cluster of aligned elements, e.g., artifacts, knowledge, markets, regulation, cultural meaning, infrastructure, maintenance networks and supply networks. Transitions are conceptualised as system innovations, i.e., a change from one sociotechnical system to another. The article describes a co-evolutionary multi-level perspective to understand how system innovations come about through the interplay between technology and society. The article makes a new step as it further refines the multi-level perspective by distinguishing characteristic patterns: (a) two transition routes, (b) fit–stretch pattern, and (c) patterns in breakthrough.     

Why England? Demographic factors, structural change and physical capital accumulation during the Industrial Revolution

Why did England industrialize first? And why was Europe ahead of the rest of the world? Unified growth theory in the tradition of Galor and Weil (2000, American Economic Review, 89, 806–828) and Galor and Moav (2002, Quartely Journal of Economics, 177(4), 1133–1191) captures the key features of the transition from stagnation to growth over time. Yet we know remarkably little about why industrialization occurred much earlier in some parts of the world than in others. To answer this question, we present a probabilistic two-sector model where the initial escape from Malthusian constraints depends on the demographic regime, capital deepening and the use of more differentiated capital equipment. Weather-induced shocks to agricultural productivity cause changes in prices and quantities, and affect wages. In a standard model with capital externalities, these fluctuations interact with the demographic regime and affect the speed of growth. Our model is calibrated to match the main characteristics of the English economy in 1700 and the observed transition until 1850. We capture one of the key features of the British Industrial Revolution emphasized by economic historians — slow growth of output and productivity. Fertility limitation is responsible for higher per capita incomes, and these in turn increase industrialization probabilities. The paper also explores the availability of nutrition for poorer segments of society. We examine the influence of redistributive institutions such as the Old Poor Law, and find they were not decisive in fostering industrialization. Simulations using parameter values for other countries show that Britain’s early escape was only partly due to chance. France could have moved out of agriculture and into manufacturing faster than Britain, but the probability was less than 25%. Contrary to recent claims in the literature, 18th century China had only a minimal chance to escape from Malthusian constraints.     

资本形成路径与资本存量调整模型——基于中国转型时期的分析

本文综合考察了我国生产性资本的总量水平、形成路径及其调整机制。通过改进的方法所估算的资本存量在改革开放以来已经翻了不止两番 ,年平均增长率为7 3 6 % ,积累极为迅速。资本形成路径明显分为两个阶段 ,增量改革推动的配置效率改进使资本—产出比率在 1 994年之前持续下降 ,而近年来的资本形成过快是由于经济增长越来越倚重资本深化 ,必须通过全方位结构调整加快转型进程。本文进一步给出了我国转型期资本存量调整的供求决定框架 ,实证结果表明 ,需求导向的资本存量调整机制和投资行为已经在中国的转型经济中基本形成 ,产出水平与资本成本均为资本调整与投资需求的主要决定因素     

共享资源治理制度转型中个体认知状态的实证研究

基于对认知行为与制度演化的认识,在偏好分层理论框架下,本文针对“既非家庭私有又非社会公有的被一定范围内私人共享”的共享资源治理制度转型,通过对南京市两次截面数据(2003年878个、2005年865个样本)的统计分析,考察了共享资源治理制度转型中个体认知状态:面临转型期复合场景信号作用,个体外层偏好关系和认知状态发生冲突———趋于支配共享资源决策权利、同时回避与之对应、对等的供给责任。对两次截面数据所做的方差分析显示,存在认知冲突的个体比例未发生显著变化,但各变量特征变化表明,新场景下治理关系的认知状态调整将有利于共享资源治理转型。     

Lessons from the transition process

The illusions that market mechanism would transform former communist countries easily into welfare states were gradually replaced by disappointments. Major problems are common to all countries in transition; they all endured an unprecedented fall in measured output and rise of unemployment. Four countries: former Czechoslovakia, Hungary, Poland, and Slovenia constitute a group in which the fall was the lowest and which also have reached the bottom. While the mechanisms of depression in these countries differ basic links of the vicious circle seem to be similar. The transition is reflected in constitutional provisions on property rights; new constitutions depart radically from their socialist predecessors, return to the principles of French revolution, and provide more than adequate protection of private property. Equally important are legal frameworks for market activities, and privatization aimed to improve efficiency, enable fairness, and serve in the abolition of the monoparty system.     

Do converters facilitate the transition to a new incompatible technology? A dynamic analysis of converters

This paper analyzes the process of transition in standards between incompatible technologies when converters are available. Contrary to a common presumption that converters facilitate the transition from an old technology to an otherwise incompatible new technology, I find circumstances in which the possibility of transition is blockaded by the existence of converters. In the welfare analysis of converters, a distinction is made between ex ante and ex post efficiency effects. Finally, I also analyze the equilibrium behavior in the provision of converters and compare it to the socially optimal outcome.
