超越"强制性-诱致性变迁"二分法,构建动态制度变迁模型是制度经济学研究的前沿和难题。本文初步构建了一个以个体和权威为主体,包含制度变迁成本的动态演化博弈模型,并以中国农地制度变迁历程中的两个典型案例进行实证检验。研究表明,权威决策是正式规则的主要来源,个体共同认知则是非正式约束的主要来源,二者共同决定了制度变迁的方向;制度变迁成本是重要的激励约束因素,制度变迁的速度则取决于制度变迁成本与个体认知、权威决策三者的一致性程度,一个高效、有序的制度变迁过程应尽量避免三者的背离和冲突。因此,政府主导进行的农地制度改革应特别关注农民认知,尊重农民意愿;对具有高变迁成本的制度变迁采取渐进改革的方式,适时建立过渡性的制度安排,并在改革的速度与质量之间做好权衡,以减少改革阻力,提高改革效率。  相似文献

This article examines factors driving three components of total factor productivity change (TFPC) in U.S. agriculture – technical change (TC), technical efficiency change (TEC), and scale and mix efficiency change (SMEC). We also examine TFPC and contrast implications derived from the component models with those from a directly estimated TFPC model. Our results show that TC and SMEC are both significantly impacted by innovation through public research and improved human capital through education and health care access. TEC and SMEC are significantly affected by farm size, and the latter is significantly affected by public policy. The ratio of family-to-total labour, terms of trade and precipitation have significant impacts on all three components, but extension has no significant impact on any component. Climate change variables are the most impactful factors on each component as well as on TFPC. While the impact of climate change is heterogeneous across regions and components, its estimated historical impact is most often positive. Nearly all TFPC elasticities estimated directly are qualitatively the same as those calculated from the component models and quantitatively similar.  相似文献

A Production Analysis of the Manufacturing Industries in Iran   总被引:1,自引:0,他引:1  
This article is concerned with the estimation of production functions, returns to scale, and measurement of the rate of technical change using panel data. Technical change is represented by single as well as multiple time trends. The underlying production technology is represented in translog functional form. A random effects model with heteroscedastic variances is used. The models are estimated using the generalized least squares method. The disturbances of cross-sectional units are assumed to be correlated over time. Empirically, our focus is on measuring technical change in Iranian manufacturing industries during the period 1971–1993. Empirical results show that single or multiple time trend representations yield different time behavior of technical change. In the multiple time trends model, we observe a sharp decline in the pattern of technical change in 1978 in relation to the political changes. In the single time trend, as expected, the sharp decline cannot be revealed due to the smooth pattern of technical progress during the entire period of study.  相似文献

面对日趋复杂的外部环境,组织变革成为企业获得竞争力的重要方式。员工参与是组织变革成败的关键,充足的组织变革信息有利于员工积极投入变革。本文以社会信息加工理论为基础,对来自被兼并企业的36个工作团队185名员工进行研究,探索多渠道变革信息传递对员工的影响机制。基于多层次线性模型的数据分析结果表明:(1)变革情境下,组织正式渠道进行信息沟通和变革氛围包含的非正式信息,均能正向促进员工变革绩效;(2)员工所持有的积极变革期望,在多渠道信息传递和变革绩效间起到中介作用;(3)变革氛围跨层调节变革信息沟通对员工积极变革期望的正向作用,相比于低变革氛围情景,具有高变革氛围的团队,通过变革信息沟通更能显著提升员工对变革的积极期望。研究结论对企业变革实践中信息传递和沟通工作具有现实指导意义。  相似文献

变革准备是组织成员关于组织变革必要性、组织变革能力等方面的信念、态度和意图,是评价组织成员(个体或群体)变革反应的重要指标,其理论基础包括变革干预理论和动态能力理论。研究发现,自我概念、风险态度、学习动机、智商等个体因素,以及领导、沟通、组织氛围等情境因素都会影响变革准备,而变革准备直接影响员工变革意愿与变革行为,进而对组织效能产生影响。目前,变革准备研究还未形成独特的研究路径,也不足以为理论系统化提供支持,未来研究还需对变革准备的影响因素、维度结构、测量工具及内在认知机制等开展进一步探讨。  相似文献

Trade and Industry Policy   总被引:1,自引:0,他引:1  
This article consists of a review of changes in trade and industry policy, along with discussions of the determinants of change and the major problem areas. Policy between 1965 and 1985 is summarised, and the growth of unemployment in the 1970s is suggested as a key determinant of change. Higher protection in certain industries, and moves to more quantitative methods ot protection can be related to unemployment, in Australia as in other countries. Theory and empirical evidence suggest that protection is likely to prove ineffective in reducing unemployment. The reliance on protection in particular cases is ascribed to a wish by governments to preserve specific jobs, not to increase overall employment. Policy can have a role in facilitating or restricting structural change which can arise from several sources, such as changing trade patterns and preferences. The devices of policy are considered briefly to determine whether they are likely to facilitate change or not. It is concluded that they often provide incentives to avoid change. The scale problem is considered, and it is suggested that the cost of protection could be high in industries subject to significant scale economies. Scale and adjustments are considered in the light of two industries, motor vehicles and whitegoods, and the role of industry plans is examined. The actuality of trade and industry policy often differs from announced intentions, and this ambiguity can give rise to uncertainty which itself has a cost.  相似文献

The main goal of the research presented in this paper is to provide an overview of the available insights concerning radical changes in inter-organizational network structures. The following research question has been formulated: what is known about the way organizations in networks deal with, and are affected by, radical changes in inter-organizational network structures?In order to answer this question, a review of the most relevant literature dealing with changes in network structure over time is presented. The literature reviewed has been analyzed by comparing the role of change in the analysis (independent vs. dependent variable) as well as the manner in which change is conceptualized (incremental vs. radical change and dyadic vs. network change).It is found that studies that observe networks changing over time are scarce. Nevertheless, the available studies provide some interesting insights concerning the formation, evolution and termination of dyadic ties, network evolution, and the effects of (radical) changes in network structure. However, more research on several specific topics seems necessary. These topics are: the link between dyadic change and change at the network level, the evolution of network structures, the processes through which critical events lead to changes in network structures, and the effects of radical changes in network structures.  相似文献

I implement a two-stage procedure to estimate the components of real wage change in the Philippines along the wage distribution from 2001 to 2006, as well as the contribution of individual covariates to each component. The methodology is based on Re-centred Influence Functions (RIF), as suggested by Firpo et al. (2009). The advantage of this methodology is that it not only decomposes the unconditional wage change at any quantile of the wage distribution, but also allows the characterization of the contribution of any single covariate on each component. I find that real earnings of males in the Philippines declined and the decline along the earnings distribution is generally higher at higher deciles for all males and higher at lower deciles in Manila. Decomposition results are driven by the wage structure component, while the composition effect is small and generally positive with education as the main contributor. Within the wage structure effect, the main determinants are associated with changes in the rewards of experience and occupation, along with residual change (change in intercepts).  相似文献

Quantitative indices are proposed to reflect the degree of development and the potential for change of the nation-state. The former index is based upon the intensity of energy consumption, while the latter is defined as the product of agricultural land per capita and gross national product per capita. It is shown that acceptable levels of some welfare functions are achieved above a critical energy intensity called the development threshold, and it is postulated that above a higher critical level of energy intensity significant environmental deterioration will occur. Data is presented for 104 countries and high levels of change potential are shown to be correlated with a relatively large number of options for further development. On the other hand, very low levels of change potential are found in countries which have difficulty in supporting their populations. It is postulated that change potential is more useful than either population density or poverty as an indicator of when a country is in need of a vigorous population policy. It is concluded that below the development threshold further industrialization is beneficial while above it this may not be true. It is also concluded that at high levels of the change potential and at intensities below the development threshold high population growth rates may be tolerated.  相似文献

Technological Progress versus Efficiency Gain in Manufacturing Sectors   总被引:1,自引:0,他引:1  
This study decomposes the nonparametric Malmquist productivity index for 36 Korean manufacturing sectors into two components: technological change and technical efficiency change. The empirical results show that while each sector displays quite different growth patterns, productivity growth is dominated by technological change. Technological change is found to have a negative correlation with efficiency change. Secondary regression performed in this study identifies the relationship between productivity growth measures and several key policy variables, such as effective protection rate, market concentration, and so forth. The productivity estimates are compared with those of the conventional Törnqvist productivity index.  相似文献

Uncertainty and risk-aversion are notably absent in the modeling of farmers' adoption of climate change mitigation practices in developing countries even though most of the agricultural mitigation practices also have effects on yield variability. The objective of this paper is to explore the implications for climate change mitigation projects of modeling farmers as risk neutral while in actuality they behave as risk-averse agents. Results indicate that when risk averse farmers are modeled as risk-neutral agents, the size of the incentives needed to induce participation to a carbon sequestration program is miscalculated with serious implications either for the success for projects that aim at compensating for climate change mitigation services or for the economic efficiency of such projects.  相似文献

The efficiency and productivity in the Italian factoring industry between 1993 and 1997 is investigated using DEA. The factoring industry is an important part of many financial systems and it has established itself as a major source of finance and credit management for a growing number of companies. However, as far as the authors are aware no studies have applied frontier methodologies to examine the efficiency and productivity of this industry. This paper focuses on the Italian market, the second largest in the world after the UK. The results suggest that there are substantial cost savings to be had in the Italian factoring industry: the mean cost inefficiency in the Italian factoring industry over the period 1993–1997 ranged between 14% and 22%. These inefficiencies are mainly generated by allocative rather than technical inefficiencies. Scale and technical inefficiencies seem to be similar in magnitude and the supposed importance of the latter typically found in the banking efficiency literature, are not observed in Italian factoring. Firm size does not appear to be related to technical, allocative and economic efficiency and the hypothesis that ownership structure influences factoring firm efficiency could not be rejected. In order to analyse efficiency change over time the Malmquist index is used. Total factor productivity was decomposed into technical change and efficiency change and the latter was further divided into pure efficiency and scale efficiency change. Productivity changes were slight over the period 1993–1996, while a substantial increase in productivity occurred between 1996 and 1997: the latter appears to be the result of a large improvement in the technology and a positive scale efficiency change, however, this was slowed down by a negative pure efficiency change.  相似文献

The literature on global climate change has largely ignored the small but positive steps that many public and private actors are taking to reduce greenhouse gas emissions. A global policy is frequently posited as the only strategy needed. It is important to balance the major attention on global solutions as the only strategy for coping with climate change. Positive actions are underway at multiple, smaller scales to start the process of climate change mitigation. Researchers need to understand the strength of polycentric systems where enterprises at multiple levels may complement each other. Building a global regime is a necessity, but encouraging the emergence of a polycentric system starts the process of reducing greenhouse gas emissions and acts as a spur to international regimes to do their part.  相似文献

This paper is concerned with the theoretical problems of devising indexes of quality change and with some of the practical problems of constructing such indexes from market data, relating these to the various attempts to construct such indexes in the past. The general conclusion is that, while quality is inherently ordinal, there are three different indexes which might be taken as "measures" of quality change. If changes are sufficiently small, the values of all three indexes will coincide and then, only, can we consider any one of them to be an unambiguous measure of the change.  相似文献

We explore determinants of job reallocation, employment change and average job tenure in this paper. A model which associates technological advances with the process of economic growth is modified and analysed. The features of this model allow for the possibility of asymmetric behaviour when looking at the net change in employment. Workplace data from Australia (AWIRS95) are used to test the predictions generated from the model for both employment change and average job tenure. Results are presented that provide clear evidence as to the nature of workplaces in which net employment growth is concentrated. We find that employment growth is asymmetrically related to expected changes in demand for the output of the workplace. We also find that employment is lower for workplaces that are larger, older, have greater union density, offer higher relative earnings, or are operating in a more competitive environment. The impacts on average tenure are as expected from the model and from these changes in employment. Overall there is a substantial degree of agreement between the predictions of the model and our empirical results.  相似文献

The sources of aggregate productivity growth are explored using detailed data for four‐digit US manufacturing industries during 1958–96 and a decomposition formula that allows us to quantify the contribution of structural change. Labour productivity as well as total factor productivity are considered with either value‐added or employment shares serving as aggregation weights. It is shown that structural change generally works in favour of industries with increasing productivity. This effect is particularly strong in the years since 1990, in high‐tech industries and in durable goods producing industries. The impact of the computer revolution can be clearly identified.  相似文献

Climate change and its marginalizing effect on agriculture   总被引:1,自引:0,他引:1  
The agriculture of some areas considered marginal in the EU agricultural context is being questioned due to its low productivity and growing dependence on economic aid programs Common Agricultural Policy (CAP). This study shows that climate change increases these areas marginalisation of since worsens crop growth conditions. The influence of climate change on the agricultural sector is analyzed using the Multicriteria Decision Paradigm with information provided by the Erosion-Productivity Impact Calculator (EPIC) and a General Circulation Model (GCM) as inputs for multicriteria mathematical programming models. The results obtained show climate change effects on the crop portfolio. Further results suggest that climate change effects are not only economics and environmental, reducing the suitable area for crops, but also social as it causes loss of jobs in the agricultural sector.  相似文献
