Abstract

So far we have dealt only with “complete panels” or “balanced panels”, i.e., cases where the individuals are observed over the entire sample period. Incomplete panels are more likely to be the norm in typical economic empirical settings. For example, in collecting data on US airlines over time, a researcher may find that some firms have dropped out of the market while new entrants emerged over the sample period observed.
