The problem is particularly worrisome for economies that obtain a large share of their income from the exploitation of N...

I analyze the relationship between labor intensity – the wages to revenue ratio – and a firm’s risk and book-to-market ratio in a production model. Under plausible parameters, labor intensive firms are riskier and exhibit higher book-to-market ratios than capital intensive firms. Covariance with the stochastic discount factor grows with labor intensity so the return spread between labor and cap...

This paper studies the flexible-versus-dedicated technology choice and capacity investment decisions of a multi-product firm under demand uncertainty in the presence of budget constraints. The firm operates under a capital budget for financing the capacity investment, and an operating budget, which is uncertain in the capacity investment stage, for financing the production. We investigate how t...

Human capital analysis deals with acquired capabilities which are developed through formal and informal education at school and at home, and through training, experience, and mobility in the labor market. Just as accumulation of personal human capital produces individual eco...

A fundamental issue in the current debates over Marx’s value theory (in the IWGVT, on OPEL, in journal articles, etc.) is precisely what was Marx’s assumption regarding the determination of constant capital, in the case when the labor-time required to produce the means of production changes. The mostcommonly held interpretation of this issue, and my own interpretation, has been that Marx assume...
