New Study Details Safety Advantage Of Union Mines
A study by Professor Alison Morantz on whether union coal mines are safer than non-union operations is featured in this Charleston Gazette article by Ken Ward Jr.
There’s a new study out from a Stanford Law School professor that addresses an issue that comes up quite often here on Coal Tattoo: Whether union coal mines are safer than non-union operations.
The conclusion? Here’s what professor Alison D. Morantz concludes:
Although the United Mine Workers of America (UMWA) has always advocated strongly for miners’ safety, prior empirical literature contains no evidence that unionization reduced mine injuries or fatalities during the 1970s and ‘80s. This study uses a more comprehensive dataset and updated methodology to examine the relationship between unionization and underground, bituminous coal mine safety from 1993 to 2008.
I find that unionization predicts a substantial and significant decline in traumatic mining injuries and fatalities, the two measures that I argue are the least prone to reporting bias. These disparities are especially pronounced among larger mines.
My best estimates imply that overall, unionization predicts an 18-33% drop in traumatic injuries and a 27-68% drop in fatalities. However, unionization is also associated with higher total and non-traumatic injuries, suggesting that injury reporting practices differ substantially between union and nonunion mines. Unionization’s attenuating effect on the predicted frequency of traumatic injuries seems to have grown since the mid 1990s.

Olin Program in Law and Economics at Stanford.
