Declining rates of return to education: evidence for Indonesia

In 1977, American labour economist Richard Freeman documented a fall in the return to education in the US, and attributed it to the expansion of the country's education sector. This article shows, similarly, that the returns to education in Indonesia generally declined between 1993 and 2007–08, following the large-scale expansion of the sector. The changes, however, were reasonably modest, and sometimes differed between males and females. This suggests that both recent growth in the education sector (which by itself could depress the return to education) and uneven growth across the Indonesian economy (which could differentially increase demand for graduates at various levels of education) have played a role in determining the pattern of change over time in the profitability of education in Indonesia.     

An Analysis of the Effect of Schooling,Experience and Sex On Earnings in the Government and Private Sectors of Urban Java

The returns to education in Indonesia are analysed using Susenas data. The private sector is found to reward education more generously than the public sector, while the latter puts a premium on experience. A casual analysis suggests general sex discrimination against female workers at any given level of education; however, once experience is allowed for, the negative sex differentials become insignificant. Finally, the general returns to education are of the order of 15–17% additional income for each additional year of schooling, which is a very high rate of return compared with other countries.     

新疆少数民族农民个人教育收益率实证研究——基于新疆6市577户的调研数据

为了解新疆少数民族农民教育收益率的具体情况,本文在新疆六地市农民入户调研数据的基础上,对新疆少数民族农民的受教育程度和收入情况进行了分析,并采用明瑟收益函数方法对新疆少数民族农民的教育收益率进行了计量回归分析。结果发现,农民收入中,外出打工收入对新疆少数民族农民的收入水平具有重要影响;性别差异对新疆少数民族农民的教育收益率影响显著,且整体教育收益率随受教育程度的提高呈近似“u”型结构。而且新疆少数民族农民的收入水平和教育收益率与国内其他农村地区相比存在很大差距。     

Economic returns to schooling in urban China: OLS and the instrumental variables approach

This paper examines economic returns to schooling in urban China using ordinary least square (OLS) and instrumental variable (IV) methodologies. First, we find that OLS estimates of the returns to education are lower in China than in other transition economies, whereas IV estimates are higher in China. Second, we find that OLS, a method for estimating the returns to education without control for endogeneity bias, may underestimate the true rates of return for men. In addition, if we do not control for endogeneity bias and the sample selection bias, we may further underestimate the true rates of return for women. Finally, we find that OLS estimates of the returns to education for men are slightly higher than for women. The IV estimates for women are higher than those for men, and this difference increases after correcting for selectivity biases.     

Does School Quality Matter? Evidence from the Hong Kong Experience

This paper analyses the differential returns to education and to language ability of natives and Chinese immigrants in Hong Kong. The large difference in quality between Hong Kong schools and Chinese schools provides a natural experiment for evaluating the effect of school quality on students' performance in the labor market. We show that the rate of return to schooling is more than three times higher among local-born workers than among Chinese immigrants to Hong Kong. Our analysis also suggests that English language education is one important component of the success of the Hong Kong education system.     

“关系”和教育对中国居民收入的影响——基于CGSS调查数据的实证分析

文章基于全国综合社会调查数据（CGSS）,利用OLS回归和分位数回归方法分析“关系”和教育对中国居民收入的影响。研究发现：“关系”和教育对中国居民的收入有正向促进作用,在选取有效的工具变量克服了“关系”和教育的内生性之后,上述结果依然稳健,并且“关系”和教育存在负向交叉效应。“关系”的回报率随着收入的增加而上升,而教育的回报率却随收入的增加而下降。比较“关系”和教育在不同的分位点对城镇居民和农村居民收入的影响后发现,农村居民“关系”的回报率随收入的增加而上升,而城镇居民“关系”的回报率呈“u”型,并且对在各个分位点上,城镇居民的教育回报率要高于农村居民的教育回报率。     

Wage Returns to Schooling in Nigeria

Abstract: In the last two decades, primary and secondary school enrollment rates have declined in Nigeria while enrollment rates in post‐secondary school have increased. This paper estimates from the General Household Survey for Nigeria the private returns to schooling associated with levels of educational attainment for wage and self‐employed workers. The estimates for both men and women are small at primary and secondary levels, 2–4 percent, but are substantial at post‐secondary education level, 10–15 percent. These schooling return estimates may account for the recent trends in enrollments. Thus, increasing public investment to encourage increased attendance in basic education is not justifiable on grounds of private efficiency, unless investments to increase school quality have higher private returns. With high private returns to post‐secondary schooling, students at this level should pay tuition, to recoup more of the public costs of schooling, which may be redistributed to poor families through scholarships.     

英语技能在中国劳动力市场的工资溢价测算

作为人力资本的一种形式,语言能力在劳动力市场很可能有一定的经济回报。文章采用CFPS、CLDS和CGSS三套数据,检验了英语的工资回报效应。总体上,英语存在显著的"工资溢价"效应,且这种效应具有异质性。例如,年龄较大、受教育程度较高、从事管理和技术职业以及东部地区劳动者的英语经济回报率显著,同时英语能力对城市居民的影响要大于农村居民,对城市本地居民的影响要大于农民工。另外,在工资回报率上,英语的听说能力要明显大于英语的读写能力,而口语的作用又要大于听力。     

Does Education Still Pay Off in Rural China： Revisit the Impact of Education on Off-farm Employment and Wages

The present study considers how education affects off-farm job participation and wages. We use a nationally representative dataset from a survey conducted in 5 provinces, 101 villages and 808 households by the authors in early 2005. The empirical results show that educational attainment, skill training and years of experience of rural residents have positive, statistically significant effects on off-farm employment. The average return to a year of education is 7percent, which is higher than those observed in previous studies. We also find the return to an additional year of schooling to be higher for post-junior high schooling than for junior high and below schooling： 11.8 versus 3.2 percent. We conclude that not only does education still pays off in rural China, but also the rate of return to education is increasing over time.     

Correlations in Returns and Volatilities in Pacific-Rim Stock Markets

Most studies on the correlations in stock returns and volatilities focus on the contemporaneous relationships and spillover effects in major stock markets such as the US and Japan. This paper adds to the literature by focusing on the dynamic relationship in the volatilities of the returns in the Pacific-Rim stock markets. The causality in variances test method of Cheung and Ng (1996), a multivariate GARCH model and VAR analyses are employed to model conditional volatilities and study the dynamic responses of volatilities to innovations in conditional variances. The results suggest that while the stock markets are correlated in returns and volatilities contemporaneously and with lags, idiosyncratic factors play important roles in national stock markets. In addition, the dynamic adjustment of the market return volatilities can take a much longer time than previously reported in some of the countries studied.     

Consistency between Sakernas and the IFLS for Analyses of Indonesia’s Labour Market: A Cross-Validation Exercise

This article assesses the consistency between Indonesia’s National Labour Force Survey (Sakernas) and the Indonesia Family Life Survey (IFLS) for analyses of the country’s labour market. I show that Sakernas and the IFLS depict different levels of and changes in labour-market indicators. My estimates of the labour-force participation model, the sector-choice model, and the Mincer model are all statistically different between the two surveys, although the magnitudes are similar for labour-force participation and sector choice. The IFLS shows a much higher return to education than Sakernas, according to the Mincer model. In addition, I find that the cross-sectional sample of the IFLS and the panel sample of the IFLS corrected for attrition yield similar coefficient estimates from all equations. The findings in this article provide an important reference for researchers interested in using Sakernas and the IFLS—either individually or combined—to analyse labour-market issues in Indonesia.     

Private rates of return to education of Africans in South Africa for 1995: a Double Hurdle model

In this study, the private rates of return to education of African males and females in South Africa are estimated. Both Heckman's (1976) two-stage selection model and the more recent Double Hurdle model, with correlated errors between the participation and employment equations, is found to be more suitable for the earnings analysis than the one with uncorrelated errors. This might imply that people make the decisions to participate in the labour force and to take up a job offer simultaneously. The private rate of return to education of Africans is found to be 12 and 11 per cent for males and females, respectively. These rates are significantly higher than those found in previous analyses of rates of return to education in South Africa. In these older studies, the private rate of return to education of Africans was found to vary from 2,5 to 7,7 per cent.     

The Relation between Aggregate Earnings and Security Returns over Long Intervals*

This paper provides a theoretical explanation and consistent empirical evidence for the increase in the contemporaneous correlation between returns and aggregate earnings as the return interval is lengthened. Consistent with intuition and with Easton, Harris, and Ohlson 1992, the analysis shows that aggregation over time renders the lag in accounting recognition relatively less important and thus improves the returns‐earnings R². Interestingly, the analysis also reveals that aggregating earnings over longer periods increases the positive covariance between aggregate earnings and the accounting lag, which may further increase the R². This positive covariance can lead to an earnings coefficient greater than one over some range of aggregation, which is consistent with the findings of Easton et al. that over the 10‐year interval the returns‐earnings regression slope coefficient is greater than one (1.7). The empirical results highlight the fact that the slope coefficient, which is greater than one and increasing with the interval, accounts for much of the increment to the returns‐earnings R². In fact, constraining the slope coefficient to be one results in an R² of 11 percent for the 10‐year interval, which is considerably lower than the R² of 47 percent when the regression is unconstrained. Hence, the positive covariance between current earnings and the accounting lag, rather than the diminishing effect of the accounting lag, appears to be the dominant explanation for the observed high R² over long intervals.     

非农就业提高农村居民幸福感了吗？

农村劳动力非农转移已经成为常态,对农村居民的福利水平产生了深远影响。文章基于体验效用假设,构建了工农要素流动下农村居民的幸福函数,并基于2018年中国家庭追踪调查(CFPS)农村调研数据,实证分析了非农就业影响农村居民幸福感的效应、机制与情境。结果表明:非农就业在总体上促进了农村居民幸福感提升,但却存在一定的"伊斯特林悖论"关系,即短期非农就业能够显著促进幸福增长,但长期非农就业对幸福增长的促进作用是有限的,甚至出现停滞或反向抑制状态;其内在机制主要在于非农就业过程中农村居民的需求层次逐渐由生存需要转向尊重和自我实现需要,但长期非农就业并不能显著提升外出务工农村居民的社会地位感知;非农就业对农村居民幸福感的促进效应,在本地非农就业和跨省流动的就业情境下更为显著,在女性群体、高中层次受教育程度群体中相对更高,且伴随农村居民的年龄增长呈现边际递减规律。基于此,文章提出创造本地就业市场、关注非农劳动力的就业需求变化、加强非农就业劳动力职业技能培训等针对性政策启示。     

An Index‐Based Model for Determining the Investment Benchmark of Renewable Energy Projects in South Africa

In a globalised world, financial markets observe the optimal level of asset allocation and returns based on risk inherent in the economies. Whether public or private investors, they need to have an optimal return on their investment given the finite resources. In relatively new sectors like grid‐connected renewable energy, many investors face difficulty in assessing proper return, making them more averse to financing such projects, affecting transborder project development opportunities. In developing countries like South Africa, which has tremendous potential for renewable energy projects, an arbitrary choice of the required rate of return for project evaluations can negatively affect funding decisions. This paper explores an index‐based model to make fair estimates of the required equity benchmark internal rate of return (IRR) using financial markets observation for renewable energy projects in South Africa. The index‐based model is parsimonious and captures common macroeconomic factors. More specifically, it provides a simple and effective mechanism to calculate IRR for renewable energy projects given different gestation periods.     

Do Interest Rate Liberalization and Fintech Mix? Impact on Shadow Deposits in China

In this paper we attempt to characterize the stability of shadow deposits in China with interest rate liberalization and fintech developments. We emphasize that shadow banks provide higher but riskier returns and such characteristics affect the stability of shadow deposits. In our setting, the stability of shadow deposits is influenced by two offsetting effects, namely: the patience effect, which makes investors more willing to wait because of the potentially higher returns; and the uncertainty effect, which makes investors more likely to withdraw as a result of higher risk. Under liberalized interest rates, the patience effect will erode and the uncertainty effect will be heightened because the post‐liberalization higher return of traditional banks undermines the importance of the extra return of shadow deposits to depositors, while preserving the importance of the risk aspect. Fintech development is modeled as a reduction in the withdrawal cost that facilitates runs. This affects the stability of shadow deposits because of their wider fintech reliance. Regulators should be cautious in pushing interest rate liberalization and fintech application alongside building a safety net for shadow banking.     

Determinants of Self-employment in China： Evidence from Cross-regional Data

This paper presents and tests a series of sources of regional variations in self‐employment rate in China in the 2000s, and illustrates that the stage of economic development is a major explanation for the variations of self‐employment rate across regions over the past decade. The negative relationship between the stage of economic development and self‐employment rate identified in the paper indicates that China has entered the process of fast industrialization, and self‐employment is playing a diminishing role in economic growth and employment. We also find a substitution effect between self‐employment and private enterprises. While both are important components of China's private sector, private enterprises are becoming an increasingly important source of China's economic growth and employment. Furthermore, our findings also imply that when job opportunities are limited, self‐employment in China is likely a forced choice of disadvantaged people who are not qualified for wage jobs.     

Strategic Asset Allocation for China＇s Foreign Reserves： A Copula Approach

In this paper, we study strategic asset allocation for China＇s foreign reserves using a risk- based approach. Four aspects of the risk management are investigated： an investment universe, dependence structure, allocation strategies under risk minimization and trade-off between risks and returns. A regime-switching copula model is developed to investigate the dynamic dependence between assets. One regime emphasizes a short-term safe asset and the other regime emphasizes a long-term safe asset. The optimal allocation is derived following two strategies： risk minimization and trade-off between risks and returns in utility maximization with disappointment avoidance, lf the central bank focuses solely on risk minimization, the asymmetries in the asset return dependence encourage the flight to safety. However, if higher risks are allowed in exchange for higher returns, even the exchange is very conservative, and the asymmetries would discourage the flight to safety. Therefore, we suggest that China should mitigate its flight to safety after 2008 and increase holdings of short-term bank deposits, long-term treasury bonds and euro bonds.

Basic education and income inequality in Brazil

This paper attempts to elucidate the long-term impact of basic education on income inequality in Brazil. It does so, first, by examining how investment in basic education affects incomes and, second, by assessing the extent to which government involvement in the financing of education services and the taxing of the returns of education investment contributes to the achievement of a more equitable distribution of income.On the basis of the empirical evidence available in Brazil, it is possible to suggest that: (i) education per se cannot significantly reduce inequality, (ii) government policies in terms of education subsidies and taxes on lifetime earnings do not show a clear redistribution pattern, and (iii) there exist effective policy tools in the area of employment, education wastage, cost recovery practices which could help bridge the gap between rates of return to education and reduce income inequality.
