Is the time-series evidence on minimum wage effects contaminated by publication bias?

Existing meta-analysis approaches to testing for publication bias are probl ematic when applied to time-series studies in economics, because changes in parameters can generate spurious Evidence of publication bias. We suggest an alternative test in such contexts, and apply it to time-series studies o f the effects of minimum wages on employment. In contrast to recent researc h by Card and Krueger [1995a], we find that the results of published time-s eries studies of minimum wage effects ar-e consistent with structural chang e, and that the null hypothesis of no publication bias is not rejected by t he evidence.
