Housing prices and the high Chinese saving rate puzzle

China's over 25% aggregate household saving rate is one of the highest in the world. One popular view attributes the high saving rate to fast-rising housing prices in China. However, cross-sectional data do not show a significant relationship between housing prices and household saving rates. This article uses a simple consumption-saving model to explain why rising housing prices per se cannot explain China's high household saving rate. Although borrowing constraints and demographic changes can translate housing prices to the aggregate saving rate, quantitative simulations of our model using Chinese time-series data on household income, housing prices, and demographics indicate that rising mortgage costs can increase the aggregate saving rate by at most 2 to 4 percentage points in the best down-payment structure.     

Concepts and Measures of Saving: Selected Issues for South Africa

South African household savings rates have been declining steadily over the last five decades, raising concerns that the population structurally under‐saves. Against the background of new saving‐enhancing policy initiatives, this paper asks to what extent the concern is founded, and whether the measurement of saving is really appropriate to guide economic policy. Comparing different macroeconomic concepts and measurements of saving, we show that the measure of saving in the national accounts (the residual between income and expenditure) understates the household savings rate compared to other measures. Specifically, an alternative measure from the balance sheets (the change in wealth) yields a significantly higher and non‐declining figure. While households have not been “putting aside” their incomes, they have nevertheless grown richer, driven largely by the appreciation of asset valuations. We also examine the impact of taking non‐financial saving and wealth into account, and conclude that household sector saving on the aggregate is significantly higher than the national accounts suggest. However, these adjusted measures are most relevant for the upper tail of the income and wealth distribution, raising important distributional concerns.     

Understanding High Saving Rate in China

This paper presents a detailed analysis of the Chinese saving rate based on the flow of funds data. It finds that the most widely adopted view of precautionary saving, which is regarded as the top reason for maintaining a high saving rate in China, is misleading because this conclusion is drawn from the household survey data. In fact, the household saving rate has declined dramatically since the mid‐1990s, as is observed from the flow of funds framework. The high national saving rate is attributed to the increasing shares of both government and corporation disposable incomes. Insufficient consumption demand is caused by the persistent decrease in percentage share of household to national disposable income. Government‐ directed income redistribution urgently needs to be improved to accelerate consumption, which in turn would make the Chinese economy less investment‐led and help to reduce the current account surplus.

中国城镇居民储蓄率的影响因素:1997～2008——基于省级动态面板数据的实证研究

本文在生命周期-持久收入模型与预防性储蓄理论的框架内,使用1997～2008年的省级面板数据,通过动态系统广义矩的估计方法对中国城镇居民储蓄率的影响因素进行了实证研究。研究显示:持久收入的增加和储蓄惯性显著提高了城镇居民的储蓄率,并且以上两方面因素可以对1997～2008年间城镇居民储蓄率增幅中的大部分进行解释;但与传统的LC-PIH模型不同,少儿抚养比与中国城镇居民储蓄率之间存在着显著的正相关关系。此外,社会保障事业的发展通过降低不确定性,从而显著降低了城镇居民储蓄率,而就业的市场化程度却产生了与之相反的影响。但公共支出的结构、通货膨胀率以及实际利率没有对城镇居民储蓄率产生显著的影响。     

Real wages and the family: Adjusting real wages to changing demography in pre-modern England

This paper uses demographic data drawn from Wrigley et al.'s (1997) family reconstitutions of 26 English parishes to adjust Allen's (2001) real wages to the changing demography of early modern England. Using parity progression ratios (a fertility measure) and age specific mortality for children and parents, model families are predicted in two reference periods 1650–1700 and 1750–1800. These models yield two levels of interesting results. At the individual family level, we can measure how different families' real wages changed over the family life cycle as additional children were born. At the aggregate level, we can predict thousands of families using Monte Carlo simulation, creating a realistic distribution of median family real wages in the economy. There are two main findings. First, pregnancy and lactation do not create cyclical effects in the family's income. Instead, most families' welfare ratios decline steadily across the family life cycle until children begin to leave the household, increasing the welfare ratios. Second, Allen's real wages understate or match the median of the predicted demography-adjusted distributions.     

Is there income mobility in the Philippines?

Despite a more robust economic performance over the past decade compared with the 1980s and 1990s, growth in average household income is still far below what might be expected given the pace of economic expansion in the Philippines. Inequality of household income has also remained high, which leads to the question: is there income mobility in the Philippines? Using longitudinal data from three years of the redesigned Philippine Family Income and Expenditure Survey (2003, 2006, and 2009) and a variety of analytical tools, we examine the mobility of Filipino household income and show that it is less stagnant than is conventionally perceived. Empirical evidence suggests that significant positive and negative mobility exists; albeit, the two tend to offset each other, contributing to slow household income growth at the aggregate level. In addition, there is some evidence that transitory fluctuations contribute significantly to the observed level of income mobility. Overall, the findings are robust across different analytical tools used in measuring income mobility.     

Chinese household saving and dependent children: Theory and evidence

This paper examines the impact of family size on household saving. We first study a theoretical life-cycle model that includes finite lifetimes and saving for retirement and in which parents care about the consumption by their dependent children. The model implies a negative relationship between the number of dependent children in the family and the household saving rate. Then, we test the model's implications using new survey data on household finances in China. We use the differential enforcement of the one-child policy across counties to address the possible endogeneity between household saving and fertility decisions in a two-stage least squares Tobit regression. We find that Chinese families with fewer dependent children have significantly higher saving rates. The data yields several additional insights on household saving patterns. Households with college-age children have lower saving rates, and households residing in urban areas have higher saving rates and a lower ratio of education expenditures to income. However, having an additional child reduces saving rates more for households in urban areas than in rural areas. Our regressions also indicate that saving rates vary with age and tend to be higher for households with more workers, higher education, better health, and more assets.     

Pro-poor growth and social protection in South Africa: Exploring the interactions

This study evaluates the impact of South Africa's long-term economic growth on household poverty and inequality between 1995 and 2005. We find a decline in aggregate levels of poverty, but increasing levels of inequality. The evidence suggests that the growth model provides substantial redistributive income support to the poor through the social grant programme, whilst offering few returns to those in the middle of the distribution.     

INCOME INEQUALITY IN THE PHILIPPINES, 1961–91

Household income inequality in the Philippines remains high and the trends for three decades have been fairly stable except for a sharp decline in the mid-1980s. Gini coefficient of income inequality has been consistently close to 0.50. Urbanization and education of household head are the most important factors determining the level of income inequality while the contribution of age of head is limited. The increase in the number of urban households results in an increase of overall inequality while the increase in the number of household heads with a college education tends to decrease the inequality. Among the household income sources, wage income is the largest contributor to total income inequality. Wage rate inequality appears to be a major source of wage income inequality.     

How Much Will China Save? Projecting China's National Savings Through 2040*

This paper projects China's national savings through 2040 based on China's national account data, demographic data, and data on rural and urban life‐cycle income and consumption. Our baseline projections show that China's national saving in 2040 will be 16 times the current national saving. The annual growth rate of wealth will decline from 16.3 percent in 2012 to 9.5 percent in 2040. Lowering the growth rate of wealth accumulation to the current rate of return to wealth increases consumption through 2040; lowering the growth rate of wealth further may increase consumption more in the short run, but less in the long run.     

The Wealthy Hand-to-Mouth Households in South Korea

This study establishes the stylized facts on household balance sheets in South Korea and empirically investigates their macroeconomic implications based on the concept of ‘wealthy hand-to-mouth (HtM)’ households that hold little liquid wealth with owning large amount of illiquid assets. Using a household-level panel data for the period of 2000–2014, we find that (1) there are neither deleveraging of household debts nor a sharp decline in house price even during the financial crisis, (2) run-up in household debt in 2000s is led by high-income group, (3) regardless of net worth level, wealth is highly concentrated on illiquid assets such as housing and real estate, (4) the share of wealthy HtM households is very high compared to the cases of other advanced countries. We estimate the marginal propensity to consume out of a transitory shock and find that the consumption response of HtM households is larger compared to the non-credit-constrained group, posing a threat to macroeconomic stability. Using discrete choice models with fixed effects, we also find that a household that acquire more real estate assets is more likely to become wealthy HtM when its income is relatively lower or its indebtedness is relatively higher. We discuss the characteristics of HtM households and the role of macroprudential policy.     

Fertility decline and the heights of children in Britain, 1886–1938

In this paper we argue that the fertility decline that began around 1880 had substantial positive effects on the health of children, as the quality–quantity trade-off would suggest. We use microdata from a unique survey from 1930s Britain to analyse the relationship at the household level between the standardised heights of children and the number of children in the family. Our results suggest that heights are influenced positively by family income per capita and negatively by the number of children or the degree of crowding in the household. The evidence suggests that family size affected the health of children through its influence on both nutrition and disease. Applying our results to long-term trends, we find that rising household income and falling family size contributed significantly to improving child health between 1886 and 1938. Between 1906 and 1938 these variables account for 40% of the increase in heights, and much of this effect is due to falling family size. We conclude that the fertility decline is a neglected source of the rapid improvement in health in the first half of the twentieth century.     

Global rebalancing: Effects on trade and employment

A sustained reduction of global current-account imbalances must include a decline in the share of household consumption in aggregate demand in the United States and the opposite development in China. Accordingly, import demand would decline in the United States and increase in China. Given non-homothetic demand preferences, the resulting change in the income distribution of global import demand affects both the intensity and pattern of other countries’ exports. Simulations suggest that, for the world economy, the net effect of this shift would be a decline in industrial exports, especially from labor-intensive sectors producing consumer durables. A multilaterally coordinated rebalancing that would also include an increase in the share of household consumption in aggregate demand of developed country surplus economies would reduce these adverse effects on trade and employment. Apart from the countries undertaking rebalancing, developing countries in East and South-East Asia face the greatest adjustment pressure from global rebalancing.

Demographic Effects on Personal Saving in the Future

After briefly examining the various proposed causes for the decline in the U.S. personal saving rate in the past decade, this essay then argues that a shift in the demographic composition of the population will be a much more important cause for a decline in personal saving in the future. A change in the balance between those in the labor force who are saving and retirees who are dissaving will result in a considerable fall in the aggregate saving rate under most assumptions. The simulation model used to examine this phenomenon takes into account the interest rate, the growth rate of the economy, the retirement age. the growth of population, and the life expectancy. Attention is also given to certain consequences of the fall in the saving rate, such as changes in the interest rate, changes in asset prices, and a decline in the GDP growth rate.     

Effects of school closure on household labor supply: Evidence from rural China

This paper studies the effects of school closure on household labor supply exploiting China's large-scale rural primary school closing during the early 2000s. Using CHNS 1991–2011 and CHIP 2007–2008 datasets and a difference-in-differences approach, we find that school closure significantly increases the total annual income of mothers of primary school-aged children, which comes virtually entirely from increases in wage income, due to more participation, more working hours, and higher wage rates. This significant positive effect can plausibly be attributed to their migration responses: mothers engage in temporary rural-urban migration to care for children following school closure. We find no effects on fathers' income and migration behavior. Our study provides the first causal estimation of the impacts of school closure on household labor supply and sheds light on the migration decision-making of rural females.     

Comparing alternative measures of household income: Evidence from the Khayelitsha/Mitchell's plain survey

Household income is widely used for economic and sociological analysis, yet little emphasis has been placed on the optimal way to gather household income data. The Khayelitsha/Mitchell's Plain Survey provides a unique opportunity to explore alternative ways of measuring household income. This study compares the estimates obtained from a household module with those obtained from detailed income data collected in the adult module of the survey. Estimates derived from individual income data tend to be higher and have greater variation than those obtained from the household module. This difference between income estimates has a material impact on the secondary analysis of income data. The Gini coefficient, a simple measure of income-inequality, is used in this study to illustrate how household income measured at the household level underestimates household income inequality.     

The unreported income and its impact on Gini coefficient in China

ABSTRACT

Unreported income is an important factor that distorts China’s household income accounting and Gini coefficient calculation. On the basis of comparing NBS household survey data and data from China’s Cash Flow Statement, this paper estimates the size and structure of unreported income in China over recent years. Our study found that about 20% of household disposable income has not been covered by existing household surveys in recent years. In 2015, the omission rate was 19.5%. Operating income and property income have the highest omission rates. Considering that unreported income is primarily owned by high-income people, China’s falling Gini coefficient since 2009 may have resulted from the statistical omission of partial incomes of high-income group. If unreported income is re-included, China’s Gini coefficient would increase by 10 percentage points rather than decrease.     

UNEMPLOYMENT AND CONSUMPTION

In this paper we argue that the aggregate unemployment rateis a valuable measure of aggregate income uncertainty. Accordingto the theory of precautionary saving, an increase in incomeuncertainty would be expected to increase saving. We use U.S.quarterly data on the consumption of motor vehicles first toexamine whether unemployment has a negative effect on consumptionand then to differentiate between the various explanations forthis phenomenon. We conclude that the negative relationshipbetween unemployment and consumption is due in large part toprecautionary saving motives.
