To study the determinants of growth between the countries of the world, researchers have
used panels of countries and observations spanning over long periods of time (e.g.1965-
1975, 1975-1985, 1985-1990).Some of these studies have focused on the effect that
inflation has on growth and found that although the effect is small for a given time
period, it accumulates over time and therefore has an important negative effect.
(a)Explain why the OLS estimator may be biased in this case.
