LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com ABSTRACT Moock et al (2003) did an attempt to analyze the returns to education in Vietnam by using Mincer earnings function based on the 1992–93 Vietnam Living Standards Survey (VLSS) data In this paper, I replicate the job of Moock et al (2003) to reestimate the returns to education by using the 2008 Vietnam Household Living Standard Survey (VHLSS) and Mincerian earnings functions, but with a different regression method, called clustered data at household level using panel commands The study reveals that (1) an additional year of schooling associates with 8.95% increasing in the average rate of return to education, comparing with only 5% in 1992/1993 In terms of gender gap, females experience higher returns to school than males (11.47% vs 8.33%) This pattern is unchanged when referring to result in 1992/1993 (6.8% vs 3.4%); (2) workers in public sector get higher rates of return to education than those in private sector (9.95% vs 5.59%) However, foreign sector is the one has the highest rates of return among the three, 11.9%; (3) university is the best option for schooling investment with the rate of return of 19% higher than upper secondary level while this number was 11% in 1992/1993 Primary level brings back 16% rate of return vs no level (13% in 1992) The rates are 10% for vocational vs primary (4% in 1992); 8% for upper secondary vs lower secondary; while only 2% for lower secondary vs primary Key Words: return to schooling, education, Vietnam, Human Capital, Mincer earnings function, clustered data, random effect model LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com TABLE OF CONTENTS CHAPTER INTRODUCTION 1.1 Problem Statement 1.2 Research Objectives 1.3 Research Questions 1.4 Research Methodology 1.5 Structure of the Thesis CHAPTER LITERATURE REVIEW 2.1 Definition 2.2 A Standard Model of Human-Capital Investment 10 2.3 Empirical Studies on Estimating Returns to Education 12 2.3.1 Selective Empirical Studies in the World 12 2.3.2 Empirical Studies in Vietnam 15 2.4 Analytical Framework 19 2.5 Chapter Remarks 19 CHAPTER RESEARCH METHODOLOGY 21 3.1 Data 21 3.2 Research Methodology 23 3.3 New Approach - CLUSTERED DATA APPROACH in Estimating the Returns to Education 24 3.4 Empirical Models of the Returns to Education 27 3.5 Variable Coding 29 CHAPTER RESEARCH FINDINGS AND DISCUSSION 32 4.1 Descriptive Statistics 32 4.1.1 Distribution of the Dependent and Explanatory Variables 32 4.1.2 Descriptive Statistics of the Dataset 37 LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com 4.2 Regression Results 38 4.3 Chapter Remarks 43 CHAPTER CONCLUSION AND POLICY RECOMMENDATION 45 5.1 Conclusion of the Study 45 5.2 Policy Recommendation 46 5.3 Limitations of the Study 47 5.4 Suggestion for further Studies 48 REFERENCE LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com LIST OF TABLES Table 2.1: Empirical studies in Vietnam utilizing Mincer earnings function over the period 1992-2008 17 Table 3.1: Sample of cross-sectional data 26 Table 3.2: Sample of clustered data 27 Table 3.3: Description of the Variables and Variable Coding 30 Table 4.1: Descriptive statistics 38 Table 4.2: Earnings function by years of schooling 39 Table 4.3: Earnings function by sector of employment 40 Table 4.4: Earnings function with schooling levels (for all, males, and females) 41 Table 4.5: Private rates of return to schooling by level of education (%) 42 LIST OF FIGURES Figure 4.1: Histograms of log of earnings (by gender) 32 Figure 4.2: Histograms of log of earnings (by sector) 33 Figure 4.3: Histograms of years of schooling and log of hours worked/week 34 Figure 4.4: Scatterplots of monthly earnings and years of schooling 35 Figure 4.5: Scatterplots of monthly earnings and education levels 36 Figure 4.6: Scatterplots of monthly earnings and years of experience 36 LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com LIST OF ABBREVIATIONS ADB : Asian Development Bank GSO : General Statistics Office IV : Instrument Variable RE : Random Effect OLS : Ordinary Least Squares VHLSS : Vietnam Household Living Standard Survey VLSS : Vietnam Living Standard Survey LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com CHAPTER INTRODUCTION This chapter explains the context of the thesis, its objectives and research questions In addition, a brief of methodology is also mentioned in this part Finally, the structure of the thesis is presented 1.1 PROBLEM STATEMENT Education plays an important role in modern labor markets Hundreds of studies in many different countries and time periods have confirmed that better educated individuals earn higher wage than the less-educated ones A variety of studies have been started with the seminal work by Mincer (1974) who was the first to derive an empirical formulation of earning over the lifecycle In his basic formulation, the logarithm of earnings can be interpreted as years of schooling, years of experience and squared years of experience In Vietnam, since the Vietnam Living Standards Survey (VLSS) firstly conducted in 1992–93 till present, many studies have employed the VLSS data and the Mincerian earnings function to examine rates of return to education in Vietnam, such as: Glewwe & Patrinos, 1998; Gallup, 2002; Moock et al., 2003; Liu, 2006; Nguyen Xuan Thanh, 2006; Vu Trong Anh, 2008; Vu Thanh Liem, 2009; Doan & Gibson, 2010; etc The results are also diverse The most cite study is from Moock et al (2003), in which the authors attempt to analyze the returns to education in Vietnam by using Mincerian earnings function based on the data of VLSS 1992–93 The authors find that the estimated rates of return are quite low (4.8%) In particular, on average, the rates of return to primary and Psacharopoulos and Patrinos (2002) contains rate of return estimates for 98 countries spanning more than 30 years; Trostel, Walker and Woodley (2002) contains estimates for 28 countries; Polachek (2007) contains estimates for 42 countries; etc LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com university education are 13% and 11% But these rates are just 4% and 5% at secondary and vocational levels For higher education (colleges, universities or above), the returns are higher for females (12%) than for males (10%) Now, 20 years have passed, I return to the issue and question for now, what are the returns to education in Vietnam? How have the returns changed? Especially, in term of gender gap, between males and females who receive higher returns to education? In term of sectoral gap, among public, private, and foreign sectors, any discrepancies among these three? The findings are important implications for policy makers in directing the wage and educational policies I would like to replicate the job of Moock et al (2003) to answer these questions by using the Vietnam Household Living Standard Survey (VHLSS), conducted by General Statistic Office (GSO), in 2008 and Mincerian earnings function, but with a different regression method which is first time applied in this kind of estimation, called Clustered data at household level using panel commands 2, instead of using a simple standard cross-sectional OLS estimator From the results, I would like to suggest some policy implications 1.2 RESEARCH OBJECTIVES There are 03 main objectives in this study: (1) To estimate private returns to education by years of schooling and by levels of schooling for both sexes, for males and females; and in private, public and foreign sectors recently; (2) To assess the variation in returns to education by comparing with the findings from Moock et al (2003); Please refer to the chapter on methodology (Chapter 3) for more details LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com ...
