pooled data and panel data
- Thread starter ajsa

Hi asja,
I can never remember this, I had to look this up. My favorite Chris Brooks (Into Econometrics for Finance) does not seem to distinguish; he has only panel data = cross-section + time-series.
Gujarati says:
"Panel, Longitudinal, or Micropanel Data This is a special type of pooled data in which the same cross-sectional unit (say, a family or a firm) is surveyed over time. For example, the U.S. Department of Commerce carries out a census of housing at periodic intervals. At each periodic survey the same household (or the people living at the same address) is interviewed to find out if there has been any change in the housing and financial conditions of that household since the last survey. By interviewing the same household periodically, the panel data provides very useful information on the dynamics of household behavior"
so i guess panel is pooled but the "unit of analysis" that is measured over time is the same constant entity/unit ... if the distinction is profound, I am unaware...David
