This paper studies a generalization of the Schumpeterian models with endogenous market structure that allows the overall production structure to be more than linear in the growth driving factor and yet generates endogenous growth, defined as steady-state, constant, exponential growth of income...

This paper integrates fertility choice and exhaustible resource dynamics in a tractable model of endogenous technological change. The analysis shows that, under the right conditions, the interdependence of population, resources and technology produces a transition from unsustainable...

We derive the quantitative implications of reducing sustained budget deficits (labeled fiscal stabilizations) in the context of a general equilibrium model of innovation-led growth. In the model, innovation comes from entrant firms creating new products and incumbent firms improving own existing...

We formulate and estimate a general equilibrium model of innovation-led growth and use it to evaluate the quantitative implications of individual income tax reforms for innovation and aggregate productivity growth. In the model, innovation comes from entrants creating new products and incumbents...

We study the impact of corporate governance frictions in an economy where growth is driven both by the foundation of new firms and by the in-house investment of incumbent firms. Firms' managers engage in tunneling and empire building activities. Active shareholders monitor managers, but can...

We model distribution, the delivery of goods to customers, as an activity governed by its own technology and undertaken by firms subsequently to production operations. We then use the model to investigate how distribution shapes innovation-driven economic growth. We contrast two canonical...

Empirical studies show that pollution is one of the world's most significant causes of premature death. However, despite its importance macroeconomics still largely neglects this negative externality. To fill the gap, we build a model where productivity growth, emissions, mortality and fertility...

In media markets, consumers spread their attention to several outlets, increasingly so as consumption migrates online. The traditional framework for studying competition among media outlets rules out this behavior by assumption. We propose a new model that allows consumers to choose multiple...

We construct and estimate a model that features endogenous growth and technology diffusion. The spillover effects from research and development provide a link between business cycle fluctuations and long-term growth. Therefore, productivity growth is related to the state of the economy. Shocks...
