We examine the effects of mining booms in Indonesia on labor market outcomes using exogenous price changes and 452 mines. We do this using labor force surveys between the years 1998 and 2011, and four waves of individual panel data between 1997 and 2014. Surprisingly, female incomes grow during mining booms, not because women work more, but because their work moves from the agricultural to the service sector where paid work is more common. Men experience mixed labor market changes. High average mining incomes attract male labor to mining districts, allowing for some adjustment of labor supply to demand. Suggestive evidence also shows that informal work increases marginally for men, potentially in auxiliary mining jobs. A male dominated industry that supports economic opportunities for women can unexpectedly benefit women as well.
