The relative stability of aggregate labor's share constitutes one of the great macroeconomic ratios. However, relative stability at the aggregate level masks the unbalanced nature of sectoral labor's shares. We present a two-sector (manufacturing and services) model with induced innovation that...

The Appalachian Regional Commission’s definition of the Appalachian region is the one used most often by scholars, politicians, and the popular press. The uncritical use of this definition of Appalachia raises issues of both selection bias and excess heterogeneity in regression analysis of...

We consider a decentralized version of the neoclassical growth model where labor share is chosen by workers to maximize their long run (permanent) wages. In this framework, if the labor share increases relative to the competitive share, workers capture a larger share of a smaller total income in...

This paper examines the determinants of convergence in the marginal product of capital. We develop an empirical model from Solow’s growth model and augment it to include global factors of financial flows and capital embodied in commodity trade. Using data from 52 countries during the period...

Understanding international differences in the emissions intensity of trade and production is essential to understanding the effects of greenhouse gas limitation policies. We develop data on emissions from 41 industrial sectors in 39 countries and estimate the CO2 emissions intensity of...

I introduce "Expectational Business Cycles" where output fluctuates due to learning, heterogeneous forecasting models and random changes in the efficient forecasting model. Agents use one of two forecasting models to forecast future variables while heterogeneity is dictated via an evolutionary...

We explore the relationship between union density and labor’s shares using panel data on 35 industries, spanning the entire US economy, for the years 1983 through 2005. For the full sample, a standard deviation increase in union density (membership or coverage rates) is associated with an...

Conventional monetary theory suggests that a closed system banking regime may lead to a systematic and uniform over-expansion of circulation. However, Selgin (2001, 2010) argues that as the number of banks increases, they act much as a “chain gang” does, making coordination all the more...

This paper explores a novel way to evaluate the extent to which R&D knowledge embodied in intermediate inputs correlates with productivity at the industry level. We propose the concept of R&D content of intermediates, which represents the R&D stock embodied in intermediate goods used in...

I introduce patents into a general equilibrium model of innovation, where innovators choose between creating a new product market and competing in an existing market. Patent holders demand royalties from sequential innovators, but are constrained by the ability of innovators to work around...
