Beyond the Average Elasticity – Applying Quantile Panel Regression

چکیده
This paper employs quantile panel regression to the study of fuel price elasticities. Contrasting with standard panel approaches, this method reveals the impact of explanatory variables across all points in the conditional distribution of the response variable while controlling for unobserved heterogeneity. Applying quantile panel regression to German household data demonstrates that fuel price elasticities are very high in magnitude – below -0.8 – for a small segment of households whose car mileage is low, but that this eff ect tapers off rapidly among households with higher car mileage. These fi ndings have implications for policy instruments that rely on estimates of fuel price elasticities, for example fuel taxation. JEL Classifi cation: C21, C23, D13, Q41

متن کاملBayesian Quantile Regression with Adaptive Lasso Penalty for Dynamic Panel Data
Dynamic panel data models include the important part of medicine, social and economic studies. Existence of the lagged dependent variable as an explanatory variable is a sensible trait of these models. The estimation problem of these models arises from the correlation between the lagged depended variable and the current disturbance. Recently, quantile regression to analyze dynamic pa...
متن کاملUnconditional Quantile Regression for Panel Data with Exogenous or Endogenous Regressors∗
Unconditional quantile treatment effects are difficult to estimate in the presence of fixed effects. Panel data are frequently used because fixed effects or differences are necessary to identify the parameters of interest. The inclusion of fixed effects or differencing of data, however, changes the interpretation of the estimates. This paper introduces a quantile estimator for panel data which ...
متن کاملConditional Quantile Processes Based on Series or Many Regressors
Quantile regression (QR) is a principal regression method for analyzing the impact of covariates on outcomes. The impact is described by the conditional quantile function and its functionals. In this paper we develop the nonparametric QR series framework, covering many regressors as a special case, for performing inference on the entire conditional quantile function and its linear functionals. ...
متن کاملThe Study of Effective Factores on Pressure of Exchange Market in Developing and Developed Countries : Panel Quantile Approach
The financial crisis is one of the most important challenges facing many countries so far. One of the most important consequences of the financial crisis is the currency crisis, which creates pressure on the currency market. The purpose of this paper is to examine the pressure of exchange market among developing and developed countries that were affected of global financial crisis (2007-2009)....
