Panel Data Models - WU
A special case of a balanced panel is a fixed panel. Here we require that all individuals are present in all periods. An unbalanced panel is one where individuals are observed a different number of times, e.g. because of missing values. We are concerned only with balanced/fixed panels. In general panel data models are more ’efficient ...
