The fundamental difference is that the identical cross-sectional units (individuals, firms, cities, countries, and so on) are included in each time period during which data are collected rather than randomly selecting a cross-sectional group in each time period. Examples of well-known panel datasets include the National Longitudinal Surveys (NLS), the Panel Study of Income Dynamics (PSID), and the Survey of Income and Program Participation (SIPP).

In this chapter, you discover how panel econometric analysis helps you deal with the elusive omitted variable problem that can be present in both cross-sectional and time-series regression analysis. You also see how software can be used to implement these procedures and appropriately deal with the special challenges that arise with panel-data analysis.
