We empirically examine the determinants of adoption of information technology by primary healthcare clinics using a large sample of physician clinics from several States in the U.S. Ours is one of the first studies to intensively investigate primary care clinics. These clinics are important as...

This paper develops a new open-economy endogenous growth model where technology diffusion allows for a stable and non-degenerate world income distribution. In accordance with the empirical literature, I find that country characteristics such as the social infrastructure, the degree of openness,...

This paper traces the 11,000 year evolution of infrastructure systems during major periods of innovation, expansion and diffusion. Throughout history, the key role of the State is self-evident. Private sector involvement has waxed and waned over millennia, although at times it has been pivotal...

Longitudinal, disease-level data are used to analyze the impact of pharmaceutical innovation on longevity (mean age at death), hospital utilization, and medical expenditure in Greece during the period 1995-2010. The estimates indicate that pharmaceutical innovation increased mean age at death by...

Access to information may represent an important barrier to learning about and ultimately transferring to 4-year colleges for low-income community college students. This paper explores the role that access to information technology, in particular, plays in enhancing, or possibly detracting from,...

This paper develops a general-equilibrium model of skill-biased technological change that approximates the observed shifts in the shares of wage and non-wage income going to the top decile of U.S. households since 1980. Under realistic assumptions, we find that all agents can benefit from the...

The US labour market has experienced a remarkable polarization in the 1980s and 1990s. Moreover, recent empirical work has documented a sharp increase in the wealth to income ratio in that period. Contemporary to these inequality trends, the US faced a fast technological catch-up as European...

We consider a model of cake-eating with private information. The model captures phenomena such as trust and “security of supply” in resource-use relationships. It also predicts supply shocks as an equilibrium phenomenon: privately informed sellers have incentives to reveal resource scarcity...

There were no innovations in chemotherapy for myeloma patients during the period 1977-1997, but there have been several important innovations since 1997. We investigate the impact of recent chemotherapy innovation on the longevity of myeloma patients using both time-series U.S. data and...

What is the social value of innovations in Schumpeterian growth models? This issue is tackled by introducing the concept of Lindahl equilibrium in a standard endogenous growth model with vertical innovations which is extended by explicitly considering knowledge diffusion on a Salop (1979)...
