This paper discusses the impact of oligopolistic product markets for innovation and growth, highlighting a novel, fundamental role of spillovers. We develop a model of endogenous growth with non-tournament R&D, where spillovers raise the relative R&D efficiency of laggards. A key feature is that...

We calculate aggregate measures of mismatch in the labour market for 30 European countries. These indicators measure vertical mismatch (related to the level of education, e.g. overeducation, and undereducation) and horizontal mismatch (related to the eld of education) and are comparable across...

This paper proposes a parsimonious methodology to evaluate the impact of large urban renewal projects on public revenues. The impact is largely endogenous, external to projects and may encompass a broad range of instruments, ranging from local to regional to central governments. We look at...

Nonrenewable resource scarcity has been a traditional concern when designing optimal growth models. Technological change has played an important role in those models, since its presence is assumed to mitigate the depletion effect on extraction paths over time. We formalize the general problem of...

We take an AK model to the PWT data. In the model both technology (intratemporal) and investment (intertemporal) shocks determine the variation of the growth rate. In earlier work we looked at singular models where we extracted only the technology shock using the policy functions from dynamic...

A growth model with endogenous innovation and accumulation of high-tech and low- tech human capital is developed. The model accounts for a recently established fact about human capital composition, which stated that \the richest countries are investing proportionally less than middle income...

This paper takes an AK model to the PWT data. In the model, intratemporal and intertemporal shocks are reduced forms for different technologies, and determine the variation of the growth rate. Using the policy functions of the model we recover time series for the unobserved technology shock for...
