This paper explores the impact that advances in Information and Communication Technology (ICT) have on the behaviour of transport users and their mode choice habits in Seoul. It discusses the stated preference survey conducted in Seoul and the analysis carried out using the discrete choice...

Online appendix is available at: "https://ssrn.com/abstract=3346834" https://ssrn.com/abstract=3346834The purpose of this paper is to provide guidelines for empirical researchers who use a class of bivariate threshold crossing models with dummy endogenous variables. A common practice employed by...

This paper proposes a tail-truncated stochastic frontier model that allows for the truncation of technical efficiency from below. The truncation bound implies the inefficiency threshold for survival. Specifically, this paper assumes a uniform distribution of technical inefficiency and derives...

Because of the global increase in the consumption of low-calorie natural gas, and increasing awareness of the mid-to long-term problem with the decrease in the calorific value of natural gas, actions are needed to minimize the problems with gas appliances. Most natural gas engines for small...

We use a representative panel dataset to estimate the upward mobility of education in South Korea. Generally, over 57.2% of individuals attain education level greater than or equivalent to their parents regarding their relative ranks. We also compare the upward mobility between senior and young...

This paper proposes a one-step sieve estimator of the parameter in the semiparametric triangular model for quantile regression of Lee (2007). The proposed estimator is a penalized sieve minimum distance (PSMD) estimator developed by Chen and Pouzo (2009). We develop the asymptotic theory for the...

To better understand the role of sustainable urban development in greenhouse gas (GHG) mitigation, this study examines the paths by which urban form influences an individual household׳s carbon dioxide emissions in the 125 largest urbanized areas in the U.S. Our multilevel SEM analyses show that...

This paper proposes a tail-truncated stochastic frontier model that allows for the truncation of technical efficiency from below. The truncation bound implies the inefficiency threshold for survival and also can be used as a measure of market competition. Specifically, this paper assumes a...
