DEMOGRAPHIC SHIFT,POPULATION AGEING AND ECONOMIC GROWTH IN CHINA: A COMPUTABLE GENERAL EQUILIBRIUM ANALYSIS

Abstract. Using a computable general equilibrium (CGE) model and a given ageing profile of the population to forecast the growth path of China's economy during the twenty‐first century, this study finds that: population ageing leads to declining economic growth as labour supply shrinks and the rate of physical capital formation declines; households’ material living standards improve, albeit at a declining rate; falling domestic investment partially offsets declining national savings; and the resulting saving‐investment surplus generates a current account surplus and capital outflows. Finally, the main force that can sustain China's economic growth against the backdrop of population ageing is productivity improvement.     

Do the Rich Save More? Evidence from Canada

This paper provides new evidence on the long‐standing question of whether more affluent households save a larger fraction of their income. The major difficulty in empirically assessing the relationship between incomes and saving rates is to construct a credible proxy for long‐run income—purged of transitory fluctuations and measurement error. The Canadian Family Expenditure Survey provides us with both unusually good data on savings rates and potential predictors with which we can construct reliable long‐run income proxies. Our empirical analysis suggests that the estimated relationship between saving rates and long‐run incomes is sensitive to the predictor used to proxy long‐run income. Nevertheless, our preferred estimates indicate that, except for poorest households (who simply do not save), saving rates do not differ substantially across predicted long‐run income groups.     

CAPITAL‐ AND LABOR‐SAVING TECHNICAL CHANGE IN AN AGING ECONOMY

Does population aging and the associated increase in the old‐age dependency ratio affect economic growth? The answer is given in a novel analytical framework that allows for population aging to affect endogenous capital‐ and labor‐saving technical change. In a steady state capital‐saving technical progress vanishes, and the economy's growth rate of per‐capita variables reflects only labor‐saving technical change. The mere possibility of capital‐saving technical change is shown to imply that the economy's steady‐state growth rate becomes independent of its age structure: Neither a higher life expectancy nor a decline in fertility affects economic growth in the long run.     

Pension reforms and saving gains in the United Kingdom

The empirical validity of the effect of pension reforms on domestic savings in the UK has been investigated using an Auto‐regressive Distributed Lag (ARDL) model capable of testing for the existence of a long‐run relationship regardless of whether the underlying time series are individually I(1) or I(0). The total savings response to change in pension savings is positive and significant, but an increase in occupational pension saving appears offset by a decrease in other forms of saving. This paper concludes that there is no firm evidence that aggregate savings increase considerably because of privately funded pension schemes.     

Like Father,Like Son: Inheriting and Bequeathing

This paper incorporates indirect reciprocal behavior in the context of bequeathing decisions into an otherwise standard OLG model. We provide conditions for the existence of a unique steady state with operative bequests. Contrary to standard OLG models, we show that taking into account such behavioral interactions allows one to rationalize both an increasing and U‐shaped pattern of the inheritance to GDP ratio over time, consistent with recent empirical evidence. Moreover, the model predicts a nonlinear (U‐shaped) relationship between the size of an unfunded social security program and the long‐run stock of per capita capital, which in turn provides a novel explanation of the inconclusive empirical findings on the relationship between social security, savings and long‐run growth. Ricardian equivalence is shown to hold in a special case of the model     

Longevity and Life‐cycle Savings*

We add health and longevity to a standard model of life‐cycle saving and show that, under plausible assumptions, increases in life expectancy lead to higher savings rates at every age, even when retirement is endogenous. In a stationary population these higher savings rates are offset by increased old age dependency, but during the disequilibrium phase, when longevity is rising, the effect on aggregate savings rates can be substantial. We find empirical support for this effect using a cross‐country panel of national savings rates.     

A revalidation of the savings–growth nexus in Pakistan

The aim of this study is to understand the relationship between savings and economic growth in Pakistan over the period 1971–2011. The cointegration and the Granger causality tests are adopted to examine the relationship between the variables. The results confirm the existence of long-run equilibrium among the variables of interest. Meanwhile, savings have positively affected economic growth in both the short run and long run. The Granger results also show that savings Granger-cause economic growth. Based upon these findings, we confirm that savings is a catalyst of growth for the Pakistani economy. Additionally, our results seem more likely to support the capital fundamentalists because the long run estimation as well as the Granger causality results also indicates that savings growth can effectively spur economic growth in Pakistan.     

OPTIMAL GROWTH, GENUINE SAVINGS AND LONG-RUN DYNAMICS

Green accounting theories have shown that negative genuine savings at some point in time imply unsustainability. Consequently, recent studies advocate the use of the genuine savings measure for empirical testing: a negative index implies that sustainability be rejected. However, this criterion cannot ascertain sustainability, because positive current genuine savings do not rule out genuine dissaving in the future. This paper derives a one‐to‐one relationship between the sign of long‐run genuine savings and the limiting condition for sustained utility in the capital‐resource growth model, assuming technical progress and resource renewability. This result suggests to extend the genuine saving method to include a test of the limiting condition: if this condition is empirically rejected, positive current genuine savings are delivering a false message.

Determinants of the adjusted net saving rate in developing economies

The adjusted net saving rate, initially known as the genuine saving rate, was first published by the World Bank in the late 1990s as a more comprehensive measure of national saving and one more indicative of sustainable development. The adjusted net saving rate incorporated not just physical capital depreciation, but natural capital depletion and environmental damage, as well as including some human capital formation. In this paper, using a cross‐section of developing economies for 2001–2006, determinants of the adjusted net saving rate are estimated. For comparison, the same determinants for the gross national saving rate are estimated. Also, a basic Solow growth model is extended to incorporate natural resources and to justify a more comprehensive measure of savings, such as the adjusted net saving rate, for modeling economic growth. The two measures of savings are then compared as determinants in estimations of economic growth. Understanding the determinants of the adjusted net saving rate is useful for policies to promote sustainable development.     

Chinese Saving Rates from 1953 to 2012: Trends,Compositions and Prospects

This study conducts a long‐run analysis on the trends and components of Chinese saving rates from 1953 to 2012. We identify two structural changes in aggregate saving rates around 1978 and 2001, and examine them through a decomposition analysis of the income distribution and sector‐specific saving rates. The following key findings are obtained. First, the major trends and compositions of Chinese saving rates changed markedly over the period considered, which explains the changes of aggregate saving rates with the dramatic economic transition from a planned economy to a market‐oriented economy. Second, we investigate the surge in aggregate saving rates from 2001 to 2012 based on a series of institutional factors, such as the evolving labour market, domestic economic policy adjustments and changes in external economic conditions caused by China's accession to the World Trade Organization in 2001 and the 2008 global financial crisis. Finally, we present the future prospects for the high aggregate saving rates in China based on several evolving economic, demographic and policy trends. We argue that Chinese saving rates have peaked in recent years and that a declining trend is expected, which will contribute to the economic rebalancing of the country.     

Heterogeneity,saving-investment dynamics and capital mobility in Latin America

The purpose of this paper is to analyze the dynamics of national saving-investment relationship in order to determine the degree of capital mobility in 12 Latin American countries. The analytically relevant correlation is the short-term one, defined as that between changes in saving and investment. Of special interest is the speed at which variables return to the long run equilibrium relationship, which is interpreted as being negatively related to the degree of capital mobility. The long run correlation, in turn, captures the coefficient implied by the solvency constraint. We find that heterogeneity and cross-section dependence completely change the estimation of the long run coefficient. Besides we obtain a more precise short run coefficient estimate compared to the existent estimates in the literature. There is evidence of an intermediate degree of capital mobility, and the coefficients are extremely stable over time.      

Global accumulation and accounting for national economic identity

As accumulation has globalized, national economic indicators such as the balance of payments have been increasingly called on to provide popular measures of national economic performance. Yet at the same time the possibility of defining the national economy as a unit is becoming more ambiguous. Reliance on conventional national indicators in the context of globally integrated accumulation is leading systematically to reinforce the subordination of labor to capital on a global scale.     

The impact of sub‐national institutions

This paper assesses the effect of sub‐national institutions on the economic performance of Russia's regions (oblasts, republics, krais and okrugs) from 2001 to 2008, a period of rapid economic advancement and recentralization. Approximating sub‐national institutions with the RA Expert index of investment risk, we find that a reduction in investment risk by one standard deviation increases output by 1.4 percent in the short run and 11.9 percent in the long run, suggesting a substantial regional performance gap in government practices, despite intensive political recentralization. Assuming that the main components of effective governance are running satisfactory public health programmes aimed at decreasing overall mortality among the working‐age population, creating fair labour market conditions and improving the regional institutional climate to encourage investment in fixed assets, we argue that sub‐national institutions remain important for growth in post‐Soviet Russia after 2000. This paper contributes to the literature on institutional persistence.     

LONG‐RUN VERSUS SHORT‐RUN PERSPECTIVES ON CONSUMER SCHEDULING: EVIDENCE FROM A REVEALED‐PREFERENCE EXPERIMENT AMONG PEAK‐HOUR ROAD COMMUTERS

Earlier studies on scheduling behavior have mostly ignored that consumers have more flexibility to adjust their schedule in the long run than in the short run. We introduce the distinction between long‐run choices of travel routines and short‐run choices of departure times, using data from a real‐life peak avoidance experiment. We find that participants value travel time higher in the long‐run context, supposedly because changes in travel time can be exploited better through the adjustment of routines. Schedule delays are valued higher in the short run, reflecting that scheduling restrictions are typically more binding in the short run.     

经济增长、人口结构变化与中国高储蓄

本文以生命周期理论为出发点,并运用中国1989—2006年的省际面板数据考察了经济增长、人口年龄结构变化以及它们的交互作用对中国储蓄率的影响。我们通过不同的识别方式和各种计量方法实证检验发现:市场经济转型带来的经济高速增长与人口政策转变带来的抚养系数下降导致中国储蓄率不断上升,经济增长对储蓄率上升的贡献随着适龄劳动人口数量的增加而被强化,但会随着人口老龄化程度的加深而被弱化。在使用了不同的识别方法与计量技术并控制了其他潜在影响中国储蓄率的各种因素后,我们的结果基本稳健。     

Global Integration of Central and Eastern European Financial Markets—The Role of Economic Sentiments

This paper examines the importance of different economic sentiments for the Central and Eastern European countries (CEECs) during the transition process. We first analyze the importance of economic confidence with respect to the CEECs' financial markets. Since the integration of formerly strongly‐regulated markets into global markets can also lead to an increase in the dependence of the CEECs' economies on global sentiments, we also investigate the relationship between global economic sentiments, domestic income, and share prices. Applying a restricted cointegrating VAR (CVAR) framework, which allows us to distinguish between the long‐run and the short‐run dynamics, our results for the short run suggest that economic sentiments are influenced by share prices but also offer some predictive power with respect to the latter. What is more, European sentiments play an important role in particular for the CEECs' income and sentiments.     

中国高储蓄率问题探究——1992-2003年中国资金流量表的分析

本文以国家统计局公布的1992—2003年中国资金流量表为基础,从收入分配和部门储蓄倾向等两个方面对居民、企业和政府等国内三个部门的储蓄率进行了比较分析。我们发现,尽管居民部门的储蓄率最高,但是,自1992年以来,它实际上呈逐步下降趋势,其主要原因在于居民部门获得的劳动报酬、财产收入和再分配收入均有所下降;企业储蓄率呈现缓缓上升趋势,主要原因并不在于企业盈利能力的提高,而在于其主要支出——对居民部门的劳动报酬支出和利息支出长期被稳定在较低的水平上;政府储蓄率在经历了上个世纪的低位徘徊之后,于2000年以后急剧上升,其主要原因在于,通过初次分配和再分配,政府的可支配收入在国民收入的分配中占据了越来越大的份额,同时政府部门的储蓄倾向也在不断提高。本文的政策建议是:为了实现以提高国内消费率为核心的经济发展战略,我国的经济运行应全面转向以改善收入分配结构、提高居民收入为重点的轨道上。为达此目的,加速财政政策向公共财政转型,增加公共支出和对居民的福利支出,在提高劳动生产率的基础上提高企业对劳动者的支付水平,应成为今后我国宏观调控的长期任务。     

Financial Development and Economic Activity in Advanced and Developing Open Economies: Evidence from Panel Cointegration

This study considers the effects of financial development on output in a panel cointegration framework, focusing on the implications of trade and financial openness. Our analysis indicates that after controlling for cross‐sectional dependence, the typical relationship between finance and output does not hold in the long run. This relationship, however, is re‐established once we account for economic openness. While trade openness emerges as more important for developing countries, financial openness is more important for advanced economies. In the long run, causality runs from financial development to output in the advanced economies, while in developing economies causality is bidirectional. There is no short‐run causality between financial development and output, however.     

STABILITY OF THAI BAHT: TALES FROM THE TAILS

We demonstrate how the EVT‐based signalling approach for currency crises can be applied to an individual country with a small sample size. Using Thai historical data, first, we study the tail characteristics of the distributions of two Thai baht instability measures and 21 economic fundamentals. Then, we test asymptotic dependence between the currency instability measures and lagged economic fundamentals. Empirically, we find that the distributions of both currency instability measures and economic variables are heavy tailed. Assuming a normal distribution for the variables tends to underestimate the probability of extreme events. Furthermore, most of the economic variables which are usually used as signalling indicators for currency crises are asymptotically independent of the currency instability measures. Signals issued by these variables are thus not reliable. Nevertheless, the non‐parametric EVT approach facilitates the selection of economic indicators with credible signals and high crisis prediction success.
