超常发展再铸辉煌--上海港集装箱运输发展回顾与展望

2002年,上海港创造了一个新纪录——集装箱吞吐量完成861万TEU,比上年634万TEU增长35.8%,超越高雄港而成为排名世界第四位的集装箱港口。这一辉煌业绩标志着作为我国大陆最大的国际通航港口又向国际航运中心建设的目标迈出了一大步。上海港集装箱吞吐量的发展是超常的。近10年来,它都以年均28%的增长率攀升。1994年突破100万达到119.9万TEU,从1997年至2001年的5年里,每一年都突破一个大数,分别超越200万、300万、400万、500万和600万TEU,2002年则跃升双百万,达到861万TEU。这是上海港集装箱运输发展史上前所未有的。它超常发展的巨大…     

Endogenous Growth in an Open Economy and the Real Exchange Rate

This paper is a step in the direction of a larger research project aimed at determining the long run equilibrium value of the euro/dollar real exchange rate. Given this value, one could then give a precise meaning to the notion of undervaluation or overvaluation of the euro, and calculate its misalignment. The problem however arises of how to assess the reliability of such misalignment calculations. In our opinion, we must have a benchmark (namely a period in which we exactly know from outside sources the misalignment itself), against which we can test the validity of the model underlying our calculations. This of course is not (yet) possible for the euro, so that all the calculations of the misalignment of the euro that have been made can only be compared with one another, without knowing which is the good one. Hence, before building a model to be applied to the euro/dollar, we tested our ideas incorporating them in a basic model to be applied to the lira/dollar in a period in which we do know the actual misalignment of the lira from outside sources.     

农机服务规模经营对粮食生产效率的影响机理研究

依据2009—2019年全国31个省（自治区、直辖市）的省级面板数据,运用随机前沿分析方法和Tobit模型,考量农机服务规模经营对粮食生产效率的影响及其作用机理。结果显示：2009—2019年,中国粮食生产效率总体递增,但区域间发展不平衡;农机服务规模经营通过技术引入效应和劳动力替代效应提高粮食生产效率,其中,技术引入效应的发挥受限于农业研发支出水平及其增速,劳动力替代效应在农业劳动力成本高的区域发挥的影响效用更佳。鉴于此,应加快农业科技创新,发展粮食生产全程机械化服务,完善农机社会化服务体系。     

Great Recession and Macroeconomic Theory: A Useless Crisis?

ABSTRACT

The global financial crisis of 2007–08 and the subsequent Great Recession have pushed many economists to acknowledge a fundamental limit in the theoretical models elaborated after the monetarist counter-revolution: these models disregard the financial system. The years following the Great Recession have thus been marked by the development of what can be called the ‘Financial Frictions Approach’, a theoretical approach based on the addition of the financial system to the New Keynesian DSGE model. The results of this line of research are beginning to appear also in macroeconomics textbooks. Significant examples are the publication of the seventh edition of Blanchard’s textbook, and the publication of the third edition of the textbook co-authored by Blanchard, Amighini and Giavazzi. The objective of this work is twofold: (i) to show that the new model presented by Blanchard, Amighini and Giavazzi, which reflects the results of the ‘Financial Frictions Approach’, does not allow to elaborate a coherent explanation of the Great Recession and (ii) to present the pillars of an alternative theoretical model based on the lessons of Keynes, Schumpeter and Minsky.     

The international risk sharing puzzle is at business cycle and lower frequency

Abstract We decompose the correlation between relative consumption and the real exchange rate in its dynamic components at different frequencies. Using multivariate spectral analysis techniques, we show that, at odds with a high degree of risk sharing, in most OECD countries the dynamic correlation tends to be quite negative, and significantly so, at frequencies lower than two years – the appropriate frequencies for assessing the performance of international business cycle models. Theoretically, we show that the dynamic correlation over different frequencies predicted by standard open economy models is the sum of two terms: a term constant across frequencies, which can be negative when uninsurable risk is large; a term variable across frequencies, which in bond economies is necessarily positive, reflecting the insurance intertemporal trade provides against forecastable contingencies. Numerical analysis suggests that leading mechanisms proposed by the literature to account for the puzzle are consistent with the evidence across the spectrum.     

Household Saving in Developing Countries: First Cross-Country Evidence

Although most studies have relied on domestic or private sectorsaving data, this article uses household data available fromthe U.N. System of National Accounts for a sample of 10 countries.Household saving functions are estimated using combined time-seriesand cross-country observations in order to test households'responses to income and growth, rates of return, monetary wealth,foreign saving, and demographic variables. The results showthat income and wealth variables affect saving strongly andin ways consistent with standard theories. Inflation and theinterest rate do not show clear effects on saving, which isalso consistent with their theoretical ambiguity. Foreign savingand monetary assets have strong negative effects on householdsaving, which suggests the importance of liquidity constraintsand monetary wealth in developing countries.     

The Inflationary Consequences of a Currency Changeover on the Catering Sector: Evidence from the Michelin Red Guide*

This paper examines the inflationary consequences of a currency changeover in the catering market. Empirical evidence from the Michelin Red Guide shows that: (i) differently from restaurants in non‐euro countries, restaurants in the euro area experienced abnormal price increases just after the changeover; and (ii) among restaurants in the euro area, tourist restaurants are responsible for most of the abnormal price increases. These results suggest that proposed explanations for the changeover effect, such as menu adjustment and rounding up, are only part of the story. We present a simple model of the catering market that is consistent with the evidence.     

Finance and development: Is Schumpeter’s analysis still relevant?

In recent years, numerous studies have been published highlighting the role of financial structures in the development process of contemporary economies. In these recent studies, there is always a reference to the pioneering work of Schumpeter; in particular in the writings of Rajan and Zingales [Rajan, R., Zingales, L. 2003a. Banks and markets: The changing character of european finance, NBER Working Paper Series, No. 9595, March; Rajan, R., Zingales, L. 2003b. The great reversal: The politics of financial development in the twentieth century, Journal of Financial Economics 69, 5–50; Rajan, R., Zingales, L. 2003c. Saving Capitalism from Capitalist, Crown Business Division of Random House, New York], important elements of Schumpeter’s theoretical framework are used. These works afford us an interesting opportunity to re-evaluate the importance of Schumpeter’s contribution. The thesis put forward in this paper is that while they do indeed highlight important elements of Schumpeter’s theory, Rajan and Zingales do not take the implications thereof into account and, furthermore, they neglect certain fundamental aspects of the Schumpeterian analysis that are closely connected with the parts that they consider. This renders their work incomplete, and prevents their analysis from achieving the coherence of Schumpeter’s theory.     

Productivity, terms of trade and the ‘home market effect’

This paper analyzes the international transmission and welfare implications of productivity gains and changes in market size when macroeconomic adjustment occurs both along the intensive margin of trade (changes in the relative price of existing varieties of tradable goods) and the extensive margin (creation and destruction of varieties). We draw a distinction between productivity gains that enhance manufacturing efficiency and gains that lower the cost of firms' entry and of product differentiation. Countries with lower manufacturing costs have higher GDP but supply their products at lower international prices. Instead, countries with lower entry costs supply a larger array of goods at improved terms of trade. Output growth driven by demographic expansions, as well as government spending, is associated with an improvement in international relative prices and firms' entry. While trade liberalization may result in a smaller array of goods available to consumers, efficiency gains from deeper economic integration benefit consumers via lower goods prices. The international transmission mechanism and the welfare spillovers vary under different asset market structures, depending on trade costs, the elasticity of labor supply, and consumers' taste for varieties.
