Problem
1. Define the union wage gain and the union wage gap. Why should we care about the magnitude of the union wage gain? Why should we care about the magnitude of the union wage gap? Under what conditions will the union wage gap provide a reasonable estimate of the union wage gain?
2. What are threat and spillover effects? How do they bias our estimates of the union wage effect?
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
