Approximating the Bias of the LSDV Estimator for Dynamic Unbalanced Panel Data Models
نویسنده
چکیده
This paper extends the LSDV bias approximations in Bun and Kiviet (2003) to unbalanced panels. The approximations are obtained by modifying the within operator to accommodate the dynamic selection rule. They are accurate, with higher order terms bringing only decreasing improvements. This removes an important cause for limited applicability of bias corrected LSDV estimators.

Monte-Carlo comparison of alternative estimators for dynamic panel data models
This paper compares the performance of three recently proposed estimators for dynamic panel data models (LSDV bias-corrected, MLE and MDE) along with GMM. Using Monte-Carlo, we find that MLE and biascorrected estimators have the smallest bias and are good alternatives for the GMM. System-GMM outperforms the rest in ‘difficult’ designs. Unfortunately, bias-corrected estimator is not reliable in ...
متن کاملRegional Integration and Trade: A Panel Cointegration Approach to Estimating the Gravity Model
Using a panel data set of bilateral export flows from 12 EU countries to 20 OECD trading partners over the period 1992-2003, a panel cointegration approach to estimating the gravity model is adopted to test for the significance of European regional integration. A comparison of the results indicates that a positive and significant coefficient estimate of the EU dummy variable is found for both t...
متن کاملSpurious regression and residual-based tests for cointegration in panel data
In the first half of the paper I study spurious regressions in panel data. Asymptotic properties of the least-squares dummy variable (LSDV) estimator and other conventional statistics are examined. The asymptotics of LSDV estimator are different from those of the spurious regression in the pure time-series. This has an important consequence for residual-based cointegration tests in panel data, ...
متن کاملResponse of residential electricity demand to price: The effect of measurement error
In this paper we present an empirical analysis of the residential demand for electricity using annual aggregate data at the state level for 48 US states from 1995 to 2007. Earlier literature has examined residential energy consumption at the state level using annual or monthly data, focusing on the variation in price elasticities of demand across states or regions, but has failed to recognize o...
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...
