Income volatility,household leverage,and consumption in Korea

Using the micro household data in Korea, we examine the effects of income volatility changes on households’ leverage and consumption. We found that households who faced increased income volatility lowered their leverage ratio. A one standard deviation increase in income volatility was associated with 1.3 ∼ 1.5 percentage point decrease in the leverage ratio. The effects of income volatility changes on households’ leverage choices varied with households’ borrowing constraints and other socioeconomic backgrounds. We also found that when faced with enlarged income uncertainty, households’ income coefficients on consumption were lowered. The income coefficient of average households was estimated to be around 0.16, while households with increased income volatility were around 0.12. In particular, similar to the relations in leverage ratio changes, consumptions among potentially borrowing-constrained households and those with ‘net-short’ position in real estate assets were more affected by increases in income volatility. This can be understood that households smoothed their consumption during the periods of increased income volatility, and this was shown in the smaller consumption elasticity on income. This can be attributed to the fact that faced with increased income volatility, households lower the risk exposure of their financial net wealth by lowering their leverage ratio.     

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.     

Losing the future: Household wealth from urban housing demolition and children's human capital in China

Some literature observes the negative but not very significant effect of household wealth growth on children's educational outcomes. This surprising finding is not easily reconciled with the traditional explanation that relaxed economic constraints caused by wealth growth can promote human capital accumulation. This paper proposes an alternative explanation for the causal relationship between wealth growth and human capital, which could be negative: individuals tend to reduce human capital investment following the decline in their labor supply induced by wealth growth, given that investing in human capital is mainly for employment competitiveness. This explanation is supported by evidence from the case of urban housing demolition in China, in which affected households could obtain substantial wealth growth by considerable demolition compensation thanks to the real estate boom in China. Specifically, using two nationally representative datasets, we find that Chinese households that have experienced demolition relatively have more wealth, less labor supply, lower propensity to accumulate children's human capital, and consequently, have children with lower educational achievement. These results suggest that China's economy may be losing its momentum because of the decline in labor supply and human capital accumulation brought about by the ongoing large-scale urban housing demolition.     

Digital Financial Inclusion and Consumption Smoothing in China

In this paper, we investigate the effect of digital financial inclusion (DFI) on household consumption smoothing in China. We use four waves of the biennial China Family Panel Studies from 2010 to 2016, during which time DFI has significantly developed alongside financial technology across China. We split household income shocks into permanent and transitory components, and evaluate if DFI may help households to buffer against these shocks. We find that households are not able to insure against permanent shocks to income, but they can smooth approximately 70 percent of transitory shocks to income. We also find that DFI has diminished households’ ability to insure against transitory income shocks. This is partly because online purchase may lead to the oversensitivity of consumption to income. In addition, we find that contrary to DFI, traditional financial sector development contributes to better household consumption smoothing against transitory income shocks.     

How does housing wealth affect household consumption? Evidence from macro-data with special implications for China

Thanks to four-decade spectacular economic growth, China's households have been accumulating a stockpile of wealth. In such a context, further concerns have been raised about the relationship between wealth accumulation and improvement of economic well-being, mainly through consumption. The issue becomes even more important when considering the challenges facing China in recent years, which can be characterized by a mix of increasingly leveraged households, escalating housing price, sluggish consumption, slowing economic expansion, trade frictions with the United States, and the Covid-19 pandemic and resulting economic difficulties. With that background in mind, this paper first provides international evidence on the relationship between household consumption and wealth, especially in the form of houses. Drawing on a panel of aggregate data for fourteen countries including China, we find that household consumption positively responds to changes in housing wealth, and this link is further affected by different levels of government spending and financial development. We next relate the international evidence to the case of China, with the focus on some recent policy issues over housing regulations and consumption promotion. Importantly, as the evidence and underlying theories suggest, housing wealth-consumption association does not follow a simplistic pattern, and thus, multiple policy measures could and should be undertaken rather than merely curbing speculative activities in real estate exchanges and associated financial business.     

The impact of the rise and collapse of Japan's housing price bubble on households’ lifetime utility

This study estimates the impact of the dramatic changes in housing prices during Japan's bubble from the late 1980s to the 1990s on households’ asset accumulation and utility over their life cycle. We construct a life-cycle model explaining households’ consumption/saving and housing decisions under collateral and borrowing constraints. We estimate this model using data from the Family Income and Expenditure Survey (FIES), which includes data on households’ housing wealth estimated from objective information. Using the estimated model, we then conduct a counterfactual simulation in which we assume that housing prices remained constant during the bubble period. Doing so allows us to quantify the gains/losses of lifetime utility due to the housing price boom and bust. We find that 72.2% of the households experienced an average decrease in lifetime utility equivalent to 5.7% of lifetime income. On average, Japan's housing price boom and bust caused a loss in lifetime utility equivalent to 4.7% of lifetime income. Moreover, we compare the impact of the housing price bubble across cohorts and find that the impact was greatest for those who experienced the bubble at ages 35–45.     

Housing Wealth, Financial Wealth and Consumption in China

The paper investigates the relationship between changes in asset wealth and the trend movements of household consumption in urban China. Using the vector error correction cointegration model we demonstrate that there is a unique long-run cointegrating relationship between household consumption, disposable income, financial wealth and housing wealth in urban China. We find that housing wealth is the only factor that restores the long-run equilibrium relationship when the cointegrated system is disturbed by an external shock. In addition, our permanent-transitory variance decomposition analysis indicates that nearly all variance in the movement of consumption is permanent, supporting the classical random walk hypothesis of consumption behavior. However, a large proportion of variance in the short-run movements of housing wealth is found to be transitory.     

Income diversification,wealth, education and well-being in rural south-western Madagascar: Results from the Mahafaly region

Rural households in the Mahafaly region of south-western Madagascar have to contend with low economic development and a risky natural environment. A survey of 665 households in the region was designed to address three research questions: what is the relationship between diversification of income sources and household wealth; how does education influence access to non-farm income sources and diversification; and how does household wealth and diversification affect well-being? The results show that the overwhelming majority of households follow a diversification strategy. Household wealth is associated with larger fields, greater crop diversity and higher diversification of income source categories. Education enhances access to high-return, non-farm income sources. Self-reported well-being is positively affected by both wealth and diversification. Better education and measures to improve inhabitants’ existing strategies for compensation of yield losses in farming are crucial for securing local livelihoods in the face of decreasing precipitation due to climate change.     

A provincial view of consumption risk sharing in Korea:Asset classes as shock absorbers

Using a unique data set on provincial net factor income flows disaggregated across the three asset classes of debt, equity and Foreign Direct Investment reinvested earnings in Korea, we investigated how these asset channels impacted consumption risk sharing during the Global Financial Crisis and the European sovereign debt crisis. Adopting spatial panel methods, this study found in the main that net factor flows of debt, equity and Foreign Direct Investment retained earnings have all contributed favourably to consumption risk sharing during these episodes, with Foreign Direct Investment retained earnings robust in its positive contribution in buffering shocks to consumption. These results suggest that one of the alleged benefits of financial integration in terms of providing the insurance needed to cushion the economy against adverse shocks is tangible and real at least in the context of Korea. We also obtain evidence that apart from asset channels, the combination of the government's social transfer payments and a certain measure of labour mobility help to contribute in mitigating shocks to consumption.     

An empirical re-evaluation of wealth effect in Japanese household behavior

This study investigates empirically the role of wealth in the behavior of Japanese households from two standpoints. One is concerned with what types of wealth are relevant in consumption decision by households. The other is which component of consumption spending is affected by wealth. We find that the liquid financial wealth appears as a significant explanatory variable in expenditure function of many commodity groups as well as total consumption. It turns out that variations of liquid wealth are responsible for about one third of the change in aggregate consumption in the boom period starting from the middle of 1980s.     

Informal settlement upgrading,assets and poverty alleviation: Evidence from longitudinal research in South Africa

This paper investigates the relationship between housing as an asset and the accumulation of other assets. Using data from a longitudinal research project stretching over nearly 25 years, we have found that besides actual income, there have also been improvements in self-perceived wealth ranking, asset holding, housing size, infrastructure access and human capital. Not all households have however benefited or been found to be better off. We have found that those households who had settled in Freedom Square after 1994 were indeed better off than the earlier settlers. Asset building is a slow process, one driven by stability (accessing urban land and secure tenure), finding an address, accessing education and finding work or remaining employed (though not necessarily in this particular sequence). Contrary to what the Department of Human Settlements suggests, we have found little evidence that informal settlement dwellers build assets by means of the secondary housing market.     

Income Uncertainty and Wealth Accumulation: How Precautionary are Taiwanese Households?*

To assess how recent job loss impacts wealth accumulation of Taiwanese households, the present study investigates the empirical relevance of the precautionary saving motive to explain measures of wealth during the past 2 decades. This study demonstrates that households facing increased transitory shock accumulate increased amounts of financial and housing wealth, whereas permanent shocks cause households to accumulate housing wealth only. Empirical results suggest an important policy implication: households in Taiwan will save less when social insurance policies are effective in reducing future transitory and permanent shocks to household income.     

Relative earnings of husbands and wives in urban China

This paper studies the relative contribution of Chinese husbands and wives to the family income in the process of economic transition. We find that the role of urban husbands as the main financial supporters of their families becomes relatively more important during economic transition. We argue that this trend may have reflected the restoration of the functions of household production and labor market in the process of economic transition. This restoration allows households to allocate time, effort and human capital investment for each household member and for each household and market activity in a more efficient way.     

The impact of retirement on household consumption in Japan

Using monthly data from the Japanese Family Income and Expenditure Survey, we examine the impact of retirement on household consumption. We find little evidence of an immediate change in consumption at retirement, on average, in Japan. However, we find a decrease in consumption at retirement for low income households that is concentrated in food and work-related consumption. The availability of substantial retirement bonuses to a large share of Japanese retirees may help smooth consumption at retirement. We find that those households that are more likely to receive such bonuses experience a short-run consumption increase at retirement. However, among households that are less likely to receive a retirement bonus, we find that consumption decreases at retirement.     

Bank financial structure in pre-crisis East and Southeast Asia

Seeking evidence on the role of bank governance in the 1997 crisis, we study financial structure and bank performance from 1987 to 1997. Financial performance ratios (capital adequacy, liquidity, profitability, and loan preference) are regressed on structural variables (bank assets, net income, administrative expenses, and time), focusing on banks’ management efficiency and financial performance. During financial liberalization, loan-preference ratios were higher, perhaps signaling more risk; so were capital-adequacy ratios. Capital adequacy falls, then rises as management size increases; profitability behaves oppositely, indicating diminishing returns. Thailand’s, Korea’s and Indonesia’s banks show stronger lending preference but weaker profitability; possible harbingers of crisis.

The quantity–quality trade-off related to investment in healthy human capital: New evidence from the implementation of the “selective two-child policy” in China

Using data from China Family Panel Studies (CFPS), and employing the “selective two-child policy” as a quasi-natural experiment, this study provides empirical evidence of Becker’s quantity-quality tradeoff theory. We find that the selective two-child policy reduced households’ investment in health insurance for their first-child. The proportion of participated families and the amount invested in health insurance declined significantly among families in which one spouse was an only child. The reduction in investment in health insurance was more substantial when the first-child was a girl and when the first-child was younger. One likely mechanism was the wage penalty for motherhood. The relaxed birth policy led to a significant reduction in women’s income. As a result, households’ financial resources became more limited, and their budgets became tighter, leading to reductions in investments in the health of first-child.     

Household indebtedness in Korea: Its causes and sustainability

This paper investigates why household debt in Korea has increased so rapidly over the past decade and whether it is sustainable, adopting a multi-faceted approach which includes a time series analysis, a quantitative analysis based on household panel data, and an analysis using a debt dynamics equation derived from the household budget constraint. A regression analysis reveals that household debt growth has been significantly related to house price increases, banks’ lax attitudes toward household lending, and financial institutions’ favorable funding conditions. Also 70–80% of the total debt increase has been accounted for by high income or newly indebted households. The debt dynamics equation analysis shows that the rapid rise in the ratio of household debt to disposable income is attributable not only to the increase in household asset purchases but also to the dampened growth in disposable income and the reduced savings rate. The sustainability analyses indicate that Korean households’ debt sustainability is unlikely to deteriorate sharply within a short period of time unless two extreme scenarios, under which house prices decline by 5% a year over the next five years, or a significantly large macroeconomic shock similar to the 1997 crisis hits the economy, would be realized.     

Income Distribution in East Asian Developing Countries: recent trends

This paper updates estimates of the trends in income distribution in the eight countries of the developing East and Southeast Asian region. In the last update by Krongkaew (1994 ), inequality was found to be increasing in the newly industrialising economies of Hong Kong, Korea, Singapore and Taiwan, while in the ASEAN−4 (with the exception of Thailand) it was declining. Since then, the region has undergone the East Asian financial crisis of 1997–98. Recent data indicate that income distribution in Hong Kong and Taiwan continues to improve. Income inequality in South Korea declined until 1993 but began to increase slowly until the crisis sharply widened the disparity. The evidence for Singapore is mixed, with one set of estimates showing a dip in inequality while another indicates a widening of income disparity during the crisis. The crisis had the immediate impact of improving income distribution in all the ASEAN–4 countries, mainly because of reductions in the income shares of the top income groups. Later data show that inequality has since risen in all of them, except for Malaysia (for which no recent data are available).
