In this study, we used the PSTR (panel smooth transition regression) model to investigate the nonlinear relationship … ; panel smooth transition regression model (PSTR) ; Schwarz's inequality ; triangle inequality …

When analyzing panel data using regression models, it is often reasonable to allow for time-varying covariate effects …. We propose a novel approach to modelling timevarying coefficients in panel data regressions, which is based on penalized …

-sectional analyses. This paper takes a step toward estimating of causal effects of milk consumption on cancer by applying panel …-country variation in a panel of up to 50 countries for 1990 to 2008. Possible methodological problems arising from omitted variables … (confounding factors), heterogeneity, and outliers are carefully discussed and a wide range of recent panel econometric estimators …

estimation with panel data illustrates the results. …This paper considers identification and estimation of ceteris paribus effects of con- tinuous regressors in … nonseparable panel models with time homogeneity. The effects of interest are derivatives of the average and quantile structural …

This paper proposes new ℓ1-penalized quantile regression estimators for panel data, which explicitly allows for … the techniques to two empirical studies. First, the new method is applied to the estimation of labor supply elasticities …
