Compulsory Schooling and the Returns to Education: A Reexamination (2016)
Preprint / Working Paper
van Huellen, S., & Qin, D. Compulsory Schooling and the Returns to Education: A Reexamination

We re-examine the effect of compulsory school law on education in the US pioneered by Angrist and Krueger (1991). We show that the standard instrumental variable approach of the education variable not only yields empirically inconsistent estimates, b...

How Credible Are Shrinking Wage Elasticities of Married Women Labour Supply? (2016)
Journal Article
Qin, D., van Huellen, S., & Wang, Q. C. (2016). How Credible Are Shrinking Wage Elasticities of Married Women Labour Supply?. Econometrics, 4(1), 1-31. https://doi.org/10.3390/econometrics4010001

This paper delves into the well-known phenomenon of shrinking wage elasticities for married women in the US over recent decades. The results of a novel model experimental approach via sample data ordering unveil considerable heterogeneity across diff...

Time to Demystify Endogeneity Bias (2015)
Preprint / Working Paper
Qin, D. Time to Demystify Endogeneity Bias. London

This study exposes the flaw in defining endogeneity bias by correlation between an explanatory variable and the error term of a regression model. Through dissecting the links which have led to entanglement of measurement errors, simultaneity bias, om... Read More about Time to Demystify Endogeneity Bias.

Resurgence of the Endogeneity-Backed Instrumental Variable Methods (2015)
Journal Article
Qin, D. (2015). Resurgence of the Endogeneity-Backed Instrumental Variable Methods. Economics. Journal articles, 9(2015-7), 1-35. https://doi.org/10.5018/economics-ejournal.ja.2015-7

This paper investigates the nature of the IV method for tackling endogeneity. By tracing the rise and fall of the method in macroeconometrics and its subsequent revival in microeconometrics, it pins the method down to an implicit model respecificatio...

Modelling Scale Effect in Cross-section Data: The Case of Hedonic Price Regression (2015)
Journal Article
Qin, D., & Liu, Y. (2015). Modelling Scale Effect in Cross-section Data: The Case of Hedonic Price Regression. Tongji yanjiu (Beijing.1980), 32(2), 97-103. https://doi.org/10.19343/j.cnki.11-1302/c.2015.02.014

An innovative and simple experiment with cross-section data ordering is carried out to exploit a basic feature between many economic variables – nonlinear scale dependence. The experiment is tried on hedonic price models using two data sets for autom... Read More about Modelling Scale Effect in Cross-section Data: The Case of Hedonic Price Regression.
