Abstract:
This paper provides the first systematic evidence of variation across states and over time in the number and quality of individuals attempting to enter a regulated profession (potential supply), and in the stringency of entry requirements. There are surprisingly large differences in the difficulty of the entry examination in the market for lawyers both across states and over time. The paper explores the possibility of a link between potential supply and the difficulty of the entry examination. At the cross-sectional level, the data is consistent with growth in potential supply leading to more difficult licensing exams. Also the timing of changes in standards at the US level is consistent with this hypothesis. However, the existing data does not allow drawing final conclusions from within-state variability in exam difficulty.
