Using Romer and Romer's new measure of monetary policy shocks to identify the AD and AS shocks

This article re-examines the series of (exogenous) Federal Funds Rate (FFR) shocks created by Romer and Romer (2004) for the period 1969:01–1996:12. We hypothesize that if Romer and Romer have constructed a reasonable set of monetary policy shocks, then including them in a small Vector Autoregression (VAR) should help to identify other structural shocks that affected the United States economy during their sample period. Using a sample period of 1971:01–1996:12 we are easily able to identify both an Aggregate Demand (AD) shock and an Aggregate Supply (AS) shock without imposing any sign or long-run restrictions. We present historical decompositions that allow us to compare the relative importance of these shocks with that of the exogenous monetary policy shocks in explaining output fluctuations during the 1973–1975, 1980–1984 and 1990–1991 business cycle episodes.     

Graphical causal models and VARs: an empirical assessment of the real business cycles hypothesis

This paper assesses the empirical plausibility of the real business cycle view that shocks to real variables are the dominant sources of economic fluctuations and that monetary policy shocks play an insignificant role in determining the behavior of real variables. I reconsider the vector autoregressive model of King et al. (Am Econ Rev 81:819–840, 1991), but propose an alternative identification method, based on graphical causal models. This method selects the contemporaneous causal structure using the information incorporated in the partial correlations among the residuals. The residuals orthogonalization which follows and the study of the impulse response functions confirm the results of King et al. (Am Econ Rev 81:819–840, 1991): permanent productivity shocks are not the dominant sources of aggregate fluctuations in US economy. I would like to thank Peter Spirtes, Marco Lippi, and Clark Glymour for helpful comments on early versions of the paper. I am also grateful to Valentina Corradi for providing me with an updated version of the King et al. (1991) data set. The usual disclaimer applies.     

Capacity utilization and technology shocks in the US manufacturing sector

The ability of real business cycle models to generate reasonable aggregate fluctuations depends on the time series properties of technology shocks measured by the change of total factor productivity. Three specifications of a non‐parametric productivity analysis which correct to different degrees for variations of capacity utilization are compared in this article using data for three‐ and four‐digit US manufacturing industries during the years 1958–1996. The results show that correcting for utilization generally leads to substantially smaller technology shocks that are less strongly correlated with growth of output and hours. Moreover, the probability of technological regress is considerably lower after the correction.     

Monetary policy shocks and productivity measures in the G-7 countries

An implication of two-country international real business cycle models is that total factor productivity should be an exogenous stochastic process. Economic theories which feature labor hoarding, variable capacity utilization, and increasing returns predict that measured productivity shifts are not exogenous; instead, expansionary aggregate demand shocks should lead to an increase in measured productivity. For each of the G-7 countries, this paper measures quarterly aggregate total factor productivity for the domestic country and its rest-of-world (G-6) counterpart. In each case the domestic productivity measures are not strictly exogenous: expansionary U.S. monetary policy shocks, as well as other G-6 monetary policy shocks, lead to productivity expansions. The evidence indicates that international business cycle models are misspecified unless they feature endogenous productivity mechanisms.Received: June 2001, Accepted: December 2001, JEL Classification: E5, F4Correspondence to: Charles L.

External monetary shocks and monetary integration: Evidence from the Bulgarian currency board

Starting July the 1st 1997, Bulgaria adopted a Currency Board (CB) monetary system. This paper aims at investigating if the adoption of the CB monetary system, which involves the cost of losing monetary autonomy, has provided a relatively better (with respect to other CEEC) monetary integration of Bulgaria with the European Monetary Union (EMU). Since Bulgarian monetary variables are endogenous under a CB, we focus on the ECB and FED interest rates as the main sources on monetary volatility. First, we find that ECB shocks are more rapidly absorbed and have less significant impact of domestic variables, with respect to other external monetary shocks (FED rate changes). Second, the responses of Bulgarian variables following changes in the ECB interest rate present lower persistence and significance, with respect to what the previous literature emphasized for other CEEC with monetary autonomy. This latter result still holds when accounting for different sources of cross-country heterogeneity outlined in the literature, thus supporting that the adoption of the CB may have worked as a rather good device in terms of integration of Bulgaria into the EMU.     

News and monetary shocks at a high frequency: A simple approach

We develop a simple approach to identify economic news and monetary shocks at a high frequency. The approach is used to examine financial market developments in the United States following the Federal Reserve’s May 22, 2013 taper talk suggesting that it would begin winding down its quantitative easing program. Our findings show that the sharp rise in 10-year Treasury bond yields immediately after the taper talk was largely due to monetary shocks, with positive economic news becoming increasingly important in subsequent months.     

US monetary policy shocks and the Chinese economy: a GVAR approach

Using a global vector auto regressive (GVAR) methodology, this article examines the impact of US monetary policy shocks on China’s major macroeconomic indicators. Our analysis reveals that a positive shock to the US money supply growth rate initially increases China’s inflation rate but after some time this effect completely disappears. This shock also raises China’s short-term interest rate and the Chinese currency appreciates against the US dollar. A positive shock to the US short-term interest rate increases China’s short-term interest rate but the real output growth and inflation rates decline and the Chinese currency appreciates.     

On the measurement and analysis of aggregate economic activity for China: the coincident economic indicators approach

This paper reviews some of China's high-frequency economic indicators and our principal findings on their selection and use. Our aim is to develop a composite index of coincident economic indicators (coincident economic index, CEI) which can be used to obtain timely information on the present state of the China's economy and provide an appropriate measure to analyze China's short-term macroeconomic dynamics. Notably, combining industrial production, retail sales, manufacturing employment, income of financial institutions and passenger traffic volume, they work well as the method for dating business cycles for China. It shows that, over the past two decades, there was one marked recession which occurred in 1988:8 to 1989:12. In addition to this business cycle chronology we also develop a growth cycle chronology based on the deviations from trend of the CE which shows that there have been four cyclical slowdowns since 1986. Whereas GDP growth lacks cyclical movements and appears to be dominated by trend and irregular movements, in contrast to GDP, the CEI works well as a measure of cyclical dynamics and can contribute to the analysis of short-term fluctuations of Chinese economic activity relative to its long-term growth.     

Germany before and after unification: A structural VAR analysis

Recent theoretical research in business cycle modelling has aimed at putting forward a unified framework for studying both short-term cycles and long-term growth. Empirical research based on structural vector-autoregression has established that the same factors which drive long-run growth also explain a large proportion of the movements of key macro variables at business cycle frequencies. The present paper aims at applying this approach to study the determinants of the post-unification downturn in Germany. The results suggest that German business cycles were not all alike. Whilst adverse supply shocks clearly matter before unification, it is primarily adverse aggregate demand shocks and a too tight monetary policy which dominate the German post-unification decline in output growth rates.     

J.M. Clark and Institutional Economics: Remarks on the Receipt of the Veblen-Commons Award

This paper outlines the contributions of J.M. Clark to institutional economics. Clark is sometimes seen as standing between institutional and neoclassical economics, but I argue that this view is not accurate. Clark was intimately involved in the definition, promotion, and defense of institutional economics in sessions of the American Economic Association and in a variety of other forums. No other member of the institutionalist group was as much involved in the professional discussion of institutional economics as J.M. Clark. In addition, Clark made a number of key contributions to institutionalist theory in the areas of psychology and economics, the costs of decision-making, overhead costs and business-pricing behavior, the accelerator mechanism and business cycles, workable and effective competition and competition policy, and social control. These contributions, together with the graduate students he trained at the University of Chicago and Columbia University, serve to place him in the center of the institutionalist movement and not on its periphery.

试析人民币对外升值与对内贬值并存

Since 2002, RMB has shown a phenomenon which is the co-existence of the external appreciation and the domestic inflation. This new monetary phenomenon has been strengthened in the context that US dollar depreciates internationally and that domestic economy is overwhelmed with excessive liquidities. The new monetary phenomenon is the reflection of the real economy that continuing trade surplus, triggered robustly by the export-driven economy, which brings a huge amount of foreign exchange reserve and accelerates sequentially the expansion of domestic money supply. Furthermore, a refrained appreciation of RMB tends to deteriorate the domestic inflation, which is not simply a traditional concept of CPI but a broad inflation parameter including a variety of asset prices. It is sure that the new phenomenon is becoming a new challenge to the macroeconomic equilibrium as well as the decision maker of monetary policy. __________ Translated from Jingji yanjiu 经济研究 (Economic Research Journal), 2007, (9): 32–48     

A new methodology for the logistic analysis of evolutionary S-shaped processes: Application to historical time series and forecasting

A new multi-logistic methodology to analyze long range time series of evolutionary S-shaped processes is presented. It conceptually innovates over the traditional logistic approach. The ansatz includes computing the residuals to an optimized multi-logistic trend curve least squares fitted to the time-series data. The elements of the residuals series are checked for autocorrelations and once detected the residuals series is further analyzed to search for eventual presence of underlying periodic structures using a truncated Fourier sine series. The method foundations ensures both a universal applicability and a capacity to disclose the existence of active clocks that can be possibly traced to the driving motors of the evolutionary character of the time series, due to the responsiveness of corresponding process to the development of economic cycles. On associating these two views, it is found that the methodology has a strong potential to improve the quality of short-term forecasts. These findings have been put to test through applications of the methodology to studying the time evolution of two commodities of strong economic and social importance (corn and steel) and good results were consistently obtained for both the analytical and forecasting aspects.     

IS model: A general model of forecasting and its applications in science and the economy

Expanding the work of Marchetti and Modis on Lotka-Volterra competition systems, a general model of Interaction Systems (IS) is introduced to describe the dynamics of multiple member interactions among different populations concerning not only biological systems but other types of systems as well. The new IS model provides us with a general framework of analysis and forecasting, where all parameters, variables, and interactions have real meaning, by using basic knowledge of each system.The proposed model can be applied to many different fields covering economic, business, social, physical, and other phenomena giving us both numerical estimates and qualitative insights of the system's dynamics. This is illustrated in two case studies. In the first case, the IS model is applied to elementary chemical reactions in order to quantify the reactions' kinetics. The result is the well known rate law of chemical reactions kinetics thus providing evidence of the proposed model's validity. In the second case, the IS model is applied to the global economy. The resulting model is tested against real global GDP data. The new IS model gave reliable estimates and proved to be considerably more accurate as compared to a similar forecast of global GDP based on the logistic growth model. Furthermore, the new model presented a basic framework of understanding the nature of major economic shifts, including the recent global recession of 2009, by studying the dynamic relationship between demand and supply.     

The Endogeneity of Optimum Currency Areas Criteria: Some Evidence from the European Union and Portugal

Observing the statistical relationship between business cycles correlation and trade intensity in the European Union, euro zone, and the Portuguese economy, we conclude that there is, in general, a positive effect that supports the endogeneity argument proposed by Frankel and Rose (The Economic Journal 108(449):pp. 1009–1025, 1998). However, if we analyse this relationship in sub-periods – 1967–1975, 1976–1985, 1986–1992, and 1993–2003 – we conclude that endogeneity hypothesis just hold in the first two, although the correlations are increasing. This could mean that, after the Single European Act in 1986, other forces beyond trade are contributing to business cycle synchronization. The Portuguese business cycle correlation with the European Union and the Euro zone had also increased in these four decades, despite the fact that endogeneity hypothesis is at a 90 percent confidence level. We also analyse the bilateral relationships between the Portuguese economy and the other European Union countries and find that the endogeneity is confirmed in just four cases: Spain, Ireland, Netherlands, and UK.     

Post Keynesian endogenous money theory: A theoretical and empirical investigation of the credit demand schedule

The article investigates the relationship between interest rates and loan amounts provided by commercial banks from both a theoretical and an empirical perspective. Theoretically, some scholars belonging to the post Keynesian endogenous money tradition advocate that a decrease (increase) in interest rates leads to a positive (negative) effect on the amount of loans demanded by households and firms. On the other hand, some heterodox economists maintain that interest rates do not stimulate firms’ credit demand but that a certain degree of influence is allowed for loans provided to households. By applying a vector autoregression (VAR) and vector error-correction model (VECM) methodology to European Central Bank and Organisation for Economic Co-operation and Development data for the eurozone, this article proposes an empirical validation of such theoretical premises by analysing the relationship between the different types of credit provided by commercial banks and the corresponding interest rates. The main results show a negative relationship between the interest rates and the credit provided for the purchase of houses. Conversely, no significant relationship is found between loans granted to enterprises and loans for the purchase of consumption goods and the corresponding interest rates.     

中国农民专业合作社多元发展格局的理论解释——基于间接定价理论模型和相关案例的分析

在运用间接定价理论模型对当前中国农业经营主体多样化的现状进行统一的理论解释后,本文将农民专业合作社发展的外部环境纳入模型分析,并应用案例对以农业经营主体为内核的农民专业合作社的发展格局进行了实证研究。研究表明：农民经纪人、农业合作组织、农业龙头企业等农业经营主体的出现是在农业生产与农业经营分工状态下（即专业化经济大于分工所产生的交易费用的状态下）各市场主体比较中间产品、最终产品和不同类型劳动的交易效率后选择不同的剩余权利赖以实现的最优组织结构的结果;农民合作组织、农业龙头企业这两类农业经营主体依托其外部环境发展出农民专业合作社;而兼业小农在这种农民专业合作社发展格局中注定是被盘剥的对象。     

The effects of upcoding,cream skimming and readmissions on the Italian hospitals efficiency: A population-based investigation

In this paper we analyze the effects of some distortions induced by the prospective payment system, i.e. upcoding, cream skimming and readmissions, on hospitals' technical efficiency. We estimate a production function using a population-based dataset composed by all active hospitals in an Italian region during the period 1998–2007. We show that cream skimming and upcoding have a negative impact on hospitals' technical efficiency, while readmissions have a positive effect. Moreover, the results indicate that private hospitals engage more in cream skimming than public and not-for-profit ones, while we observe no ownership differences regarding upcoding. Not-for-profit hospitals have the highest readmission index. Last, not-for-profit and public hospitals have the same efficiency levels, while private hospitals have the lowest technical efficiency.     

基于退耕还林工程下的农业产业-资源耦合响应——以吴起县为例

针对退耕还林工程对农业生态经济系统耦合作用方向及程度研究滞后的现实,选择吴起县为研究对象,运用1997～2008年统计年鉴数据和2010年8月的农户调研数据,探讨吴起县农业产业-资源耦合对退耕还林工程的响应过程。结果表明:"工程"的实施促使吴起县农业资源结构发生了较大变化,资源量有所增加,但与之相对应的产业并未得到相应的发展。林草资源及农村劳动力资源的大量闲置,林草产业及相关产业、果业与加工业的发展迟缓表明吴起县农业产业-资源之间没有形成合理配置,协调发展的态势,即"工程"在一定程度上改变了农业产业-资源耦合方向,但对其有效耦合作用的程度并不够。为此提出今后促进吴起县农业产业-资源有效耦合的建议。     

不同规模农户农业生产效率差异及影响因素研究——基于DEA-Tobit模型的实证分析

文章基于小麦主产区4个省份946个不同规模农户的调查数据,利用DEA模型和Tobit回归模型分析了小农户和家庭农场农业生产效率的影响机制。结果表明:家庭农场的农业生产效率明显高于小农户的农业生产效率,家庭农场的生产效率与经营规模呈倒"U"型变化特征;在影响因素方面,土地肥沃程度与农业技术指导对小农户和家庭农场的农业生产效率均有显著正向影响;家庭农场更倾向于通过提高受教育程度和增加单块耕地面积来提升农业生产效率;而小农户的农业生产效率对农户年龄和农户从事农作物种植年限呈现出较强的依赖性。基于此,建议有针对性地加大农业技术指导,适度扩大农业生产经营规模,加强小农户与新型农业经营主体之间的合作与联合,促进农业生产向高质量发展。
