Format

A data.frame with 198 observations on 37 variables:

  • year: 1980 to 1988

  • uclms: unemployment claims

  • ez: =1 if have enterprise zone

  • d81: =1 if year == 1981

  • d82: =1 if year == 1982

  • d83: =1 if year == 1983

  • d84: =1 if year == 1984

  • d85: =1 if year == 1985

  • d86: =1 if year == 1986

  • d87: =1 if year == 1987

  • d88: =1 if year == 1988

  • c1: =1 if city == 1

  • c2: =1 if city == 2

  • c3: =1 if city == 3

  • c4:

  • c5:

  • c6:

  • c7:

  • c8:

  • c9:

  • c10:

  • c17:

  • c18:

  • c19:

  • c20:

  • c21:

  • c22: =1 if city == 22

  • luclms: log(uclms)

  • guclms: luclms - luclms[_n-1]

  • cez: ez - ez[_n-1]

  • city: city identifier, 1 through 22

Notes

A very good project is to have students analyze enterprise, empowerment, or renaissance zone policies in their home states. Many states now have such programs. A few years of panel data straddling periods of zone designation, at the city or zip code level, could make a nice study.
