Panel Time-Series

چکیده
Traditionally economic panels had large number of cross-section units and relatively few time periods and econometric methods were developed for such large N small T data. More recently panels with observations for a large numbers of time periods have become available on cross-section units like rms, industries, regions or countries. These notes explore the econometric methods developed for such large N large T data. Such data allow more explicit treatment of (a) heterogeneity across units (b) dynamics, including the treatment of unit roots and cointegration and (c) cross-section dependence arising from spatial interactions or unobserved common factors.

Comparison between four dissimilar solar panel configurations
Several studies on photovoltaic systems focused on how it operates and energy required in operating it. Little attention is paid on its configurations, modeling of mean time to system failure, availability, cost benefit and comparisons of parallel and series–parallel designs. In this research work, four system configurations were studied. Configuration I consists of two sub-components arranged ...
متن کاملCombining time DEA scores using a dynamic panel data model
We define a combined DEA score to evaluate efficiency in agricultural research. The production model we propose considers efficiency measurements under variable returns to scale for each year in the period 2012–2017. We postulate a first-order autoregressive process in the presence of covariates, to explain efficiency. Powers of the autocorrelation coefficient estimated assuming a dynamic panel...
متن کاملBarley Productivity Decomposition in Iran: Comparison of TT, GI, MGI, and GTTI Approaches
In this paper, the authors present new indices for estimating technical change, return to scale, and TFP growth, as well as its decomposition. These indices, Modified General Index (MGI), Generalized Modified General Index (GMGI), and General Time Trend index (GTTI), are generalization of General Index approaches. These approaches were used for productivity decomposition of Iran's barely produc...
متن کاملStata: The language of choice for time series analysis?
Over time, Stata has come to incorporate more and more features for effective analysis of time series data, either pure time series or panel data with emphasis placed on the time series dimension of the panel. In this context, ‘time series modeling’ should be taken in the broad sense, referring to multivariate models built with data organized as time series, rather than the narrow sense of “Box...
متن کاملEconometric Analysis Using Panel Data
Introduction Different types of data are generally available for empirical analysis, namely, time series, cross section, and panel. A data set containing observations on a single phenomenon observed over multiple time periods is called time series (e.g., GDP for several quarters or years). In time series data, both the values and the ordering of the data points have meaning. In cross-section da...
متن کاملwww.econstor.eu The Error-in-Rejection Probability of Meta-Analytic Panel Tests
Meta-analytic panel unit root tests such as Fisher’s χ2 test, which consist of pooling the p-values of time series unit root tests, are widely applied in practice. Recently, several Monte Carlo studies have found these tests’ Error-in-Rejection Probabilities (or, synonymously, size distortion) to increase with the number of series in the panel. We investigate this puzzling finding by modelling ...
