Estimating Policy Impact in a Difference-in-Differences Hazard Model: A Simulation Study

open access: yesRisks
This article estimates the impact of a policy change on an event probability in a difference-in-differences hazard model using four estimators. We examine the error distributions of the estimators via a simulation experiment with twelve different ...

The Impact of Higher Education Expansion on the Educational Wage Premium in Taiwan: 1985 to 2015

open access: yesInternational Journal of Financial Studies, 2021
This research investigates the impact of higher education expansion on the educational wage premium from a long-term perspective in Taiwan. By using 1985 to 2015 Manpower Utilization Survey (MUS) data with the difference-in-difference-in-differences ...

Bayesian variable selection in hierarchical difference-in-differences models [PDF]

open access: yesStatistical Methods in Medical Research, 2021
A popular method for estimating a causal treatment effect with observational data is the difference-in-differences model. In this work, we consider an extension of the classical difference-in-differences setting to the hierarchical context in which data cannot be matched at the most granular level.

Misclassification in Difference-in-Differences Models

open access: yesSSRN Electronic Journal, 2022
The difference-in-differences (DID) design is one of the most popular methods used in empirical economics research. However, there is almost no work examining what the DID method identifies in the presence of a misclassified treatment variable. This paper studies the identification of treatment effects in DID designs when the treatment is misclassified.

Impact of the Belt and Road Initiative on environmental quality in countries along the routes

open access: yesChinese Journal of Population, Resources and Environment, 2021
China has adhered to the concept of green development since the introduction of the Belt and Road Initiative in 2013. However, as the initiative continues to advance, speculations have been raised on the possibility of its reduction of the environmental ...

Investigation on railway investment-induced neighborhood change and local spatial spillover effects in Nagoya, Japan

open access: yesJournal of Transport and Land Use, 2021
Previous studies have proven the significant causal relationship between railway investment and gentrification in some cities. However, most of them have focused on the gentry and less on the effect on other social classes.

Different algorithms, different models [PDF]

open access: yesQuality & Quantity, 2021
AbstractThis study assesses the extent to which the two main Configurational Comparative Methods (CCMs), i.e. Qualitative Comparative Analysis (QCA) and Coincidence Analysis (CNA), produce different models. It further explains how this non-identity is due to the different algorithms upon which both methods are based, namely QCA’s Quine–McCluskey ...

Identification and Inference in Nonlinear Difference-In-Differences Models [PDF]

open access: yesSSRN Electronic Journal, 2002
This paper develops an alternative approach to the widely used Difference-In-Difference (DID) method for evaluating the effects of policy changes. In contrast to the standard approach, we introduce a nonlinear model that permits changes over time in the effect of unobservables (e.g., there may be a time trend in the level of wages as well as the ...
