Equality vs Efficiency once again

The NBER reports:

If you provide very generous unemployment insurance, you may end up with more long-term unemployment. That's what economists Peter Kuhn and Chris Riddell find when they compare the long-term impact of a highly generous unemployment insurance (UI) program in the Canadian province of New Brunswick with the more modest UI program in the neighboring state of Maine. In Maine's northernmost countries, about 6.1 percent of employed men worked fewer than 26 weeks (half a year) in 1990. Across the Saint Croix River in New Brunswick, the comparative figure was more than three times as high, 20.8 percent. The more-generous UI program in New Brunswick accounts for about two-thirds of this difference, the authors estimate.
