两种增长核算方法的比较——兼论中国地区差距的决定性因素

运用增长核算来分析我国地区经济差距的决定性因素时,存在资本产出比和资本劳动比两种分解方法,不同的分解方法会得出不同的结果。研究表明,资本产出比分解方法相对于资本劳动比具有两个方面的优势:(1)核算的无偏性;(2)更具直观性的经济含义和政策启示。而且,它不仅适用于劳动增进型技术进步,同样还适用于希克斯中性技术进步和资本增进型技术进步。实证分析表明,全要素生产率对中国地区差距起着决定性作用。     

Monetary policy in the euro area: Was it too tight in the 1990s?

This paper studies the monetary policy in the euro area. An important question concerning the euro area is whether the monetary policy has been too tight in the 1990s and in turn, caused the high unemployment rates, in contrast to the economic prosperity and low unemployment rate of the U.S. Therefore, the authors explore what would have happened to the euro economy if the Central Banks had followed either the fixed or time-varying monetary policy rule of the U.S. The paper does find that the European central banks and then later the ECB overreacted to past inflation pressures.     

The effects of European integration and the business cycle on migration flows: a gravity analysis

This paper explores how European integration, economic fluctuations, and the interactions of these factors affect bilateral migration flows. It focuses on how migration flows developed in the wake of the establishment of the European Monetary Union, and whether migration flows became stronger, and more responsive to economic fluctuations, in the euro area. It estimates a gravity equation of bilateral gross migration flows on a global sample and on a sample restricted to the first 12 members of the euro area. It is found that unemployment is a strong and robust determinant of bilateral migration flows both globally and in the euro area. EU accession and the lifting of labour market restrictions on new member states had a large effect on gross migration flows. While mutual euro area membership is not associated with an overall rise in migration, it is associated with increased flows from countries where unemployment is high to those where it is lower. Migration flows among the euro-area 12 have been on an increasing trend since the late 1990s; after falls in 2009 they picked up again in 2010 and 2011. The evidence overall suggests that labour mobility plays an increasing role in the adjustment to asymmetric shocks in the EU and the euro area.     

中国装备制造业全要素生产率增长的分解:1998-2009——基于省际面板数据的研究

本文采用超越对数的随机前沿生产函数和1998-2009年的省际面板数据,测算了中国各地区装备制造业的全要素生产率(TFP)增长率,并从技术进步、技术效率变化、规模效率变化、配置效率变化四个方面对中国装备制造业全要素生产率变化的特点进行了分析。经验结果表明,样本期间内,全国以及东、中、西部地区装备制造业的TFP都有所增长,其增速皆呈现出先增后减再增的趋势;TFP增长对全国装备制造业产出增长的贡献率相对较低,仅为0.117。对TFP增长的分解发现,技术进步已成为中国装备制造业TFP增长的主要源泉,配置效率和规模效率恶化则严重阻碍了中国装备制造业TFP水平的提高。分地区来看,中部地区的TFP增长率最高,东部次之,西部最低,这主要是由于西部地区装备制造业要素配置效率的下降最为严重,东部地区规模效率的下降最为严重。

Production Costs,Scale Economies,and Technical Change in U.S. Textile and Apparel Industries

The elimination of quotas in textiles and apparel poses new threats from import competition. To survive, the sectors need to find least-cost methods of production. The production–cost structure of the U.S. textile and apparel industries is examined using a dual cost framework. A translog cost function is used to measure substitution elasticities between inputs, scale economies, and the nature of technical change. The scope for factor substitution in textiles remains limited with all substitution elasticities being less than unity. Labor and materials are complements in apparel production, but there is evidence of substitution between capital and labor. The rate of technical change is higher in textiles than in apparel. Given the intense import competition from low wage countries, in both industries, technical progress is labor saving. Overall, economies of scale are larger in apparel; however, scale economies have continued to increase in textiles.This research was supported by a grant from the National Textile Center.     

资本深化、技术进步与全球化下的劳动报酬份额

劳动报酬在国民收入中所占份额,一定程度上决定了一国最终消费需求大小。本文在新古典分配模型基础上,讨论了资本深化、技术进步以及全球化对我国劳动报酬份额影响机制,并运用省际面板数据进行实证分析。结果显示,具有资本增强属性的技术进步和过快的资本深化,偏离了现阶段我国要素禀赋结构,显著地降低了我国劳动报酬份额,全球化对提高我国劳动所得影响不明显。最后,本文给出了相关政策建议。     

A putty-clay vintage model for sectors of industry in the Netherlands

Summary A putty-clay vintage model has been estimated for five industrial sectors: food, beverages and tobacco manufacturing; textiles, clothing and footwear manufacturing; chemical industry and oil refineries; metal manufacturing, and total manufacturing. Substitutabilityex ante between labour and capital appeared to be small in the first four sectors, with textiles, clothing and footwear manufacturing as an exception. Substitutabilityex ante in total manufacturing industry is rather high: an elasticity of substitution of –0.74. Embodied technical progress is strong in all industrial sectors. In textiles, clothing and footwear manufacturing and in total manufacturing it is both labour- and capital-augmenting in nature. In the other sectors it is mainly of the labour-augmenting variety.This research has partly been made possible by a grant of the National Programme of Labour Market Research (NPAO).

Factor prices and induced technical change in the industrial revolution

Using historical data for the 1700–1914 period, this paper analyses the nature and direction of technical change in Britain. The evidence in this paper indicates that, over this long period, labour-saving technology adoption was a major response to changes in relative factor prices, thus supporting the hypothesis that ‘induced innovation’ was a major driver of technical change during the British industrial revolution. Labour saving was made possible and sustained by capital-augmenting and energy-augmenting technical change coupled with continuous capital accumulation and abundant energy supplies. This process placed the British economy on a higher capital–labour ratio equilibrium, and was the primary force driving sustained productivity growth, which further raised wages and living standards.     

An econometric analysis of the main components of M3 in the Euro area

An Econometric Analysis of the Main Components of M3 in the Euro Area. — The main result is that the four components of M3 in the euro area can be explained in terms of a small set of explanatory variables (nominal GDP and interest rates) for the sample period January 1990 — September 1999 both in terms of levels and as shares of M3. Moreover, overall cointegration tests broadly support the hypothesis of long-run stability of the demand for the components of M3 and for M3 itself in nominal terms. Around the start of Stage Three of Monetary Union significant substitution between the components of M3 is detected. A refinement of the empirical analysis takes into account the correlation of the unexplained movements of the individual components using the SUR technique.     

The euro and its consequences: What makes a currency strong?

The creation of the Economic and Monetary Union (EMU) and the introduction of the euro was one of the great events in economic history after World War II. The basic attractiveness of the euro is its large and expanding transaction size and the independent central bank which pursues price stability as its primary goal. The basic strength of the dollar is the hysteresis effect based on economies of scale and network externalities. The conclusion in the paper is that at present the hysteresis effect dominates the sheer size effect and the dollar remains the key vehicle currency while the euro has established itself as the second most widely used currency in the world. The euro depreciated against the dollar in the first three years after its introduction. In the paper the euro weakness is explained by the positive growth differential in favor of the U.S. economy caused by the advance in IC-technology and a pick-up in total factor productivity. In the medium run, the outlook for the euro is favorable. The U.S. current account deficit is unsustainable and improvements require a substantial depreciation of the dollar.Distinguished Address presented at the Fifty-Fourth International Atlantic Economic Conference, Washington D.C., October 10–13, 2002.     

Business Cycle Synchronisation with(in) the Euro Area: in Search of a ‘Euro Effect’

This paper studies business cycle synchronisation and convergence in the euro area. A set of stylised facts concerning the characteristics of the business cycle and synchronisation in the euro area is derived. It is analysed whether convergence or divergence patterns between the euro area countries changed after the introduction of the euro. In addition, a closer look is taken at the degree of business cycle synchronisation between other, i.e. non-euro area countries and the euro area average. Furthermore, a dynamic correlation analysis is carried out to broaden the scope of business cycle synchronisation further. We enrich the study with a frequency domain analysis and use the concepts of coherence, dynamic correlation and phase. Our main results are (i) that the synchronisation of business cycles in the euro area is fairly high, and (ii) that the introduction of the euro in 1999 does not seem to have generated a very strong—neither positive nor negative—impact on synchronisation. Coherence and dynamic correlation among the euro area countries, the UK, Japan and the US are also fairly high, reminding of the importance of synchronisation with the global business cycle.

The effects of changing U.S. MFN status for China

The Effects of Changing U.S. MFN Status for China. — This paper focuses on the effects of the U.S. not renewing Most Favored Nation (MFN) trade status for Chinese imports. An applied general equilibrium model is used to simulate the increase in tariffs from the column 1 (MFN) to the column 2 (non-MFN) duty level. Using 1992 data, the results show Chinese exports to the U.S. drop by approximately $11 billion, or over 50 percent. The U.S. and China both experience a decline in real income. While these results suggest MFN withdrawal would have a larger detrimental effect on the Chinese economy than on the U.S. economy, the estimates do not include Chinese retaliation.     

Is it really more dispersed?

The ECB’s one size monetary policy is unlikely to fit all euro area members at all times, which raises the question of how much monetary policy stress this causes at the national level. I measure monetary policy stress as the difference between actual ECB interest rates and Taylor-rule implied rates at the member state level. These rates explicitly take into account the natural rate of interest to capture changes in trend growth. I find that monetary policy stress within the euro area has been steadily decreasing prior to the recent financial crisis. Current stress levels are not only lower today than in the late 1990s, they are also in line with what is commonly observed among U.S. states or pre-euro German Länder.     

美国经济波动对中国经济增长的影响及其传导机制研究

在开放经济条件下,一国的经济波动会通过国际贸易、国际投资等资本的跨国流动传导到别的国家。鉴于美国已经成为中国主要的贸易伙伴和FDI来源国,其经济的波动会对中国的经济产生很大的影响,因此本文运用基于VAR模型的广义脉冲响应函数法与方差分解法,在以双边贸易与投资为传导纽带,暗含汇率变化影响的基础上定量分析了美国经济波动对中国经济冲击的长期传导机制和短期动态影响特征。冲击响应分析结果表明,美国经济对中国经济的影响更大,美国经济的波动主要通过影响中国对美国出口的途径对中国经济增长造成冲击;方差分解结果显示,中国经济对美国经济的贡献更大。     

Mechanical refrigeration, seasonality, and the hog-corn cycle in the United States: 1870-1940

This paper examines the role of mechanical refrigeration in seasonality and structural change in the U.S. hog-corn cycle, 1870-1940. This period covers an era in which the widespread adoption of mechanical refrigeration greatly affected the ability to store and transport perishable commodities. These developments in turn altered the seasonal production and price structure for many commodities, including pork. We use a new class of time series models, time-varying smooth transition autoregressions (TV-STARs), to document both the structural change and the nonlinear features observed in seasonal patterns for the U.S. hog-corn price relationship during the late nineteenth and early twentieth centuries.     

Real money balances and the productivity growth slowdown: The U.S. manufacturing sector, 1955–81

Summary and Conclusions The model of labor productivity for the U.S. manufacturing sector was developed in this paper within the context of a three-input production function where time entered as a proxy for technical change. The growth rate of labor productivity was found equal to the share-weighted contributions from growth in the capital-labor ratio, changes in the composition of the capital stock, growth in the money-labor ratio, and total factor productivity.The empirical results of this research yield three important conclusions. First, labor productivity growth has suffered a continuous and increasing retardation, the most severe of which occurred in the newly-examined 1978–81 time period. Second, real money balances were shown to have contributed to this slowdown in the same direction as, but somewhat less than, the contributions of either the capital-labor ratio or changes in the composition of the capital stock. Thirdly, a deletion of the monetary effect from the analysis results in an overestimation of the importance to productivity growth and its slowdown of both the capital-labor and the composition effect.Based upon these main empirical results, this study concludes that the real money balances held by firms in the U.S. manufacturing sector have played a non-passive role in that sector's labor productivity growth slowdown.This paper is part of the author's doctoral dissertation, written at West Virginia University.     

Recent Trends in the Skill Composition of Legal U.S. Immigrants

We examine fluctuations in the predicted educational attainment of newly arrived legal U.S. immigrants between 1972 and 1999 by combining data from the U.S. Immigration and Naturalization Service with the Current Population Survey. A mid-1980s decline gave way to a noticeable improvement in the skill base of the immigrant population between 1987 and 1993. A short decline in the quality of immigrant skills—less severe than that of the mid-1980s—took place in the mid-1990s. In 1998, the trend reverses once more: The labor market quality of new legal U.S. immigrants improves. The primary sources of the fluctuations include changes in the quality and quantity of immigrants obtaining an adjustment and variations in the distribution of source regions and entry class types among new legal U.S. immigrants.
