Firm Data

Abstract Danish manufacturing firm data reveal that 1) industries differ in within-firm worker skill (= wage) dispersion, and 2) within-firm skill dispersion positively correlates with firm productivity in industries with higher average skill dispersion. We argue that these patterns reflect technological differences between industries: firms in the “skill complementarity” industries profit from hiring similarly able workers, while the “skill substitutability” firms thrive on skill differences. Our study produces a robust, data-driven and theoretically validated classification of industries into the complementarity and substitutability groups, unveils hitherto unnoticed technological heterogeneity between industries within the same economy, and illustrates its importance through simulations.

Ambient Air Quality Standards

The Clean Air Act Amendments of 1970 provide the basis for a dramatic change in Federal air quality programs. The Act establishes new standards for motor vehicles and requires EPA to establish national ambient air quality standards, standards of performance for new stationary sources of pollution, and standards for stationary sources emitting hazardous substances. Further, it establishes procedures which allow states to set emission standards for existing sources in order to achieve national ambient air quality standards. The Act also permits the Administrator of EPA to register fuels and fuel additives and to regulate the use of motor vehicle fuels or fuel additives which pose a hazard to public health or welfare.National air quality standards for particulate matter have been established. Asbestos, mercury, and beryllium have been designated as hazardous air pollutants for which Federal emission standards have been proposed.
