This paper estimates a model of married women's labor supply in the presence of progressive taxes. The specification is based on a translog indirect utility function with normally distributed random preference parameters. The application of Roy's Identity then leads to a distribution of labor supply that involves ratios of normals.

that final demand of 55 units for commodity one generates 45.29 units of pollution, and final demand of 30 units for commodity two generates 18.44 units of pollution. From the appropriate elements in the last row of the inverse, we can calculate the coefficients of pollution generated per unit of final demand. These coefficients are 0.823 for commodity one and 0.615 for commodity two. It should be pointed out that the allocation of total pollution in (12) differs from that given by Leontief because he subdivides the total according to gross output figures rather than by final demand.
