This includes strictly exogenous variables that are correlated with unobserved permanent effects, variables subject to measurement error, and variables that are predetermined or endogenous relative to time-varying errors.
Static and dynamic linear models are covered. With the exception of error-in-variable problems, most results can be made extensive to nonlinear models with additive errors, and I make this extension explicit at times. However, nonlinear models with non-additive errors are outside the scope of this book. Some of these models, like discrete choice and sample selection models, are important tools in empirical work.
The main text is divided into three parts. In the econometrics of panel data two different types of motivations have converged.
One is the desire to control for unobserved heterogeneity; the other is the possibility of modelling dynamic responses and error components. The three parts of the book are organized around these two themes and their interrelations. Finally, Part IV contains two appendices that review the main results in the theory of generalized method of moments estimation, and optimal instrumental variables.
The introductory material in each of the chapters will be useful to anyone interested in panel data analysis.
Many topics are discussed from both small and long T perspectives, and I present empirical illustrations for both micro and macro panels. There is, however, an emphasis in the econometrics of micro panels. This page intentionally left blank Part I Static Models This page intentionally left blank 2 Unobserved Heterogeneity The econometric interest on panel data, specially in microeconometric applications, has been the result of at least two different types of motivation.
Second, the use of panel data as a way of disentangling components of variance and estimating transition probabilities among states, and more generally to study the dynamics of cross-sectional populations.
Part B – Newey
We next take these two motivations and model types in turn. Structural relations are needed for policy evaluation and often for testing theories.
The regression model is an essential statistical tool for both descriptive and structural econometrics. However, regression lines from economic data often cannot be given a causal interpretation.
Panel Data Econometrics (Advanced Texts in Econometrics)
The reason being that in the relation of interest between observables and unobservables we might expect explanatory variables to be correlated with unobservables, whereas in a regression model regressors and unobservables are uncorrelated by construction. One is the classical supply-and-demand simultaneity problem due to time aggregation and market equilibrium.
That is, a regression of quantity on price could not be interpreted as a demand equation because we would expect an unobservable exogenous shift in demand to affect not only downloads but also prices through the supply side effect of quantities on prices.
Another is measurement error: if the explanatory variable we observe is not the variable to whom agents respond but an error ridden measure of it, the unobservable term in the equation of interest will contain the measurement error which will be correlated with the regressor.
Finally, there may be correlation due to unobserved heterogeneity. This has been a pervasive problem in crosssectional regression analysis. Thus researchers have often been confronted with massive cross-sectional data sets from which precise correlations can be determined but that, nevertheless, had no information about parameters of policy interest.
The traditional response of econometrics to these problems has been multiple regression and instrumental variable models. A major motivation for using panel data has been the ability to control for possibly correlated, time-invariant heterogeneity without observing it.
Such a model is called the classical or standard linear regression model or the homoscedastic meaning constant variance linear regression model. Because this is the model to be studied in Chapter 1, let us call it simply Model 1.
These assumptions will be removed in later chapters. We shall sometimes impose additional assumptions on Model 1 to obtain certain specific results.
In general, independence is a stronger assumption than no correlation, al" ,, , , , , , , , iUF1 1. It is to realize that Model 1 implies certain assumptions that 1. We call p0 -I- xff Pi in 1. The reader might ask why we work with eq.
The answer is that 1.
For example, whereas the natural estimators of p0 and can be defined by replacing the moments of y and xf that characterize fi0 and Pi with their corresponding sample moments they actually coincide with the least squares estimator , the mean of the estimator cannot be evaluated without specifying more about the relationship between xf and vt. How restrictive is the linearity of F y, xf?

It holds if y and xf are jointly normal or if y and xf are both scalar dichotomous Bernoulli variables. Nevertheless, the linear assumption is not as restrictive as it may appear at first glance because xf can be variables obtained by transforming the original indepen dent variables in various ways.
If there is no danger of confusing x with x , we can drop the parentheses and write simply xf.
Whenever the size of an identity matrix can be inferred from the context, we write it simply as I. Most of our results will be obtained simply on the assumption that X is a matrix of constants, without specifying specific values.
We shall also discuss estimation of the error variance a 2. Solving 1. Clearly, S 0 attains the global minimum at 0. Then, geometrically, the least squares estimates are the intercept and the slope of a line drawn in such a way that the sum of squares of the deviations between the points and the line is minimized in the direction of the y-axis.
Different estimates result if the sum of squares of deviations is minimized in any other direction.
Using u, we can estimate a2 by 1.Boston, Pearson Education, In the econometrics of panel data two different types of motivations have converged. Microeconometrics: Methods and Applications. Assumption A2 is, on the other hand, an auxiliary assumption under which classical least-squares results are optimal. There will be regular problem sets and a final exam. Griliches and M. A central modelling issue is how best to accommodate heterogeneity across units.
