Summary: This paper examines panel data models with interactive-fixed effects allowing correlation between regressors and idiosyncratic error terms. A two-step profile GMM estimation procedure is proposed to estimate the parameters of interest. The first step obtains a consistent estimate of the slope coefficient using a nuclear-norm-regularization (NNR) based profile GMM procedure. The second step conducts post-NNR profile GMM estimation of the slope coefficient, factors, and factor loadings. The paper also studies the determination of the number of factors and proposes tests for the exogeneity of the regressor.

Summary: For static panel data models, exogenous averages over time of time-varying variables can serve as internal instruments if they are pretested for exogeneity. This pretest involves estimating a random effects model and selecting internal instruments with statistically significant parameters before using them in a Hausman-Taylor model. Biases of alternative estimators can then be evaluated in a Monte-Carlo simulation.

Summary: This study proposes a fixed effects panel data model with a partially linear form, allowing some coefficients to be constant while others vary based on exogenous continuous variables. By imposing conditional moment restrictions and using a three-stage estimation procedure, the study presents more efficient estimators and establishes their asymptotic properties. Furthermore, the study introduces a minimum distance estimator that combines two estimators to achieve optimal convergence rates, showing its feasibility and benefits through estimating a life-cycle hypothesis panel data model and conducting a Monte Carlo study.

Summary: This paper introduces a quantile regression estimator for panel data with nonadditive fixed effects and a nonseparable disturbance term. It uses within variation in the instruments to estimate the impact of exogenous or endogenous treatment variables on the outcome distribution. Unlike most quantile panel data estimators, the proposed estimator produces consistent estimates for small T. The paper also estimates the effect of the 2008 tax rebates on the short-term household consumption distribution.

Summary: This paper introduces a new model called fixed effects modal regression for panel data, which can provide better central tendency measure and prediction performance in skewed data. By modeling how the conditional mode of the response variable depends on the covariates and using a kernel-based objective function to simplify computation, the proposed modal regression can complement mean and quantile regression methods. The study investigates the asymptotic properties of modal estimators and demonstrates the finite sample performance through Monte Carlo simulations and real data analysis.

Summary: In this study, we examine binary response models for heterogeneous panel data with interactive fixed effects, allowing both the cross-sectional dimension and the temporal dimension to diverge. The proposed framework can be applied to practical applications such as predicting corporate failure probability and conducting credit rating analysis. The study establishes a link between maximum likelihood estimation and least squares approach, provides an information criterion for factor detection, and establishes the corresponding asymptotic theory. Moreover, extensive simulations and empirical analysis on stock returns sign prediction and portfolio analysis are conducted to validate the theoretical findings.

Summary: This study investigates the causal links between a high-PM2.5 episode in Korea and air pollutants originating from China. The findings show that transboundary air pollutants from China significantly affect the PM2.5 concentration in Korea, especially in the Seoul Metropolitan Area. Certain meteorological conditions, such as westerly winds, high pressure in China, low pressure in Korea, high temperature, and stagnant air flow, can intensify the effect of long-range transboundary transport from China.

Summary: This study proposes a potential outcomes framework to analyze spillover effects using instrumental variables. The findings suggest that intention-to-treat (ITT) parameters do not have a clear link to causally interpretable parameters, and rescaling them by first-stage estimands recovers a weighted combination of average effects. The study also analyzes the identification of causal effects under one-sided noncompliance and introduces an alternative assumption for identifying parameters of interest under two-sided noncompliance.

Summary: This paper presents the first evidence that air pollution can reduce life-threatening risky behaviors. The study examines the impact of air pollution on traffic accidents caused by risky driving behaviors in Taiwan from 2009 to 2015, using comprehensive accident records and high-resolution air quality data. The findings indicate that air pollution significantly decreases accidents with casualties caused by driver violations, and the effect is nonlinear. Moreover, this negative effect is only observed when road users can visually assess air pollution levels, suggesting that air quality primarily reduces road users' risky behaviors through visual channels rather than the respiratory system.

Summary: A varying-coefficient panel-data model with unobservable multiple interactive fixed effects is proposed, approximating each coefficient function using B-splines. A robust nonlinear iteration scheme based on the least squares method is proposed to estimate the coefficient functions, with the establishment of the asymptotic theory for the resulting estimators. Additionally, a residual-based block bootstrap method is proposed to construct pointwise confidence intervals for the coefficient functions, reducing computational burden and avoiding accumulative errors. The proposed procedure is extended to partially linear varying-coefficient panel-data models, with simulation studies and real-data analysis used to evaluate the performance of the methods.

Summary: This paper extends the spatial dynamic panel data (SDPD) model with fixed effects to a non-parametric form by relaxing the linear or nonlinear parameter structure of explanatory variables. The non-parametric spatial dynamic panel data (NSDPD) model with fixed effects retains the advantages of the SDPD model and solves the limitation that may lead to specification errors. It proposes the profile maximum likelihood (PML) method to estimate the unknown functions and shows the consistency of both parametric and non-parametric estimators under certain regularity conditions.

Summary: The study investigates whether the RCOP program has generated more employment opportunities in the East-Central Anatolia Region compared to its neighbor, the West-Central Anatolia Region. Findings show that RCOP increased only the employment rate of young people aged between 15-24, with no evidence of a positive effect for people over 24. Other governments concerned about youth unemployment and vulnerability could implement similar policies, but attention should be paid to the gender gap in employment opportunities.

Summary: This study focuses on the implementation of a gas chromatograph-photoionization detection (GC-PID) analyzer for the continuous monitoring of 1,3-butadiene (1,3-BD) levels in urban and industrial atmospheres. The study found that the concentrations of 1,3-BD recorded by the GC-PID analyzer were comparable to those obtained by active sampling, and the concentration peaks showed consistency in values and time slots. In the test of urban atmospheres, the results showed that the concentrations of 1,3-BD were related to prevailing wind direction and activities in the petrochemical zone, while other factors had minor effects on the distribution of this pollutant.

Summary: This study investigates the relationship between temperature inversions (TI) and aerosol vertical distribution in China. The results show that TI frequency, inversion strength (Delta T), and TI height (TIH) exhibit similar seasonal patterns across different regions in China. NC has a significantly higher TI frequency during summer, possibly due to the heating effect of black carbon aerosol. Aerosol optical depth (AOD) above the TIH is higher in spring and summer, indicating the presence of aerosol high-level transport over mainland China during these seasons. The study also finds that a strong inversion can suppress surface aerosols below the TI, but in regions with strong atmospheric stability, aerosols tend to accumulate above the TIH. These findings are valuable for understanding aerosol transport.
