This paper proposes computationally convenient methods for estimating linear regression models with first-order moving average, or MA(1), error structures. Conditional on alpha, the parameter of the MA(1) process, estimates of the regression coefficients may be obtained by ordinary least...

This paper develops and analyzes a macroeconomic model in which aggregate growth and fluctuations arise from the discovery and diffusion of new technologies; there are no exogenous aggregate shocks. The temporal behavior of aggregates is driven by individuals' efforts to innovate and/or make use...

In an economy with firm-specific human capital, it is shown that (i) a distribution of nonlabor income will generally induce a distribution of net returns to specific investments; (ii) at the individual level nonlabor income and net returns will be positively related over some range and...

Three key features of the employment process in the U.S. economy are that job creation is procyclical, job destruction is countercyclical, and job creation is less volatile than job destruction. These features are also found at the sectoral (goods and services) level. The paper develops,...
