This paper studies the difference between public production and public finance of public goods in a dynamic general equilibrium setup. By public finance, we mean that the public good is produced by private providers with the government financing their costs. When the model is calibrated to match...

This paper studies the aggregate and distributional implications of introducing user fees for publicly provided excludable public goods into a model with consumption and income taxes. The setup is a neoclassical growth model where agents differ in earnings and second-best policy is chosen by a...

This paper presents a new model of oligopoly in general equilibrium and explores its implications for positive and normative aspects of international trade. Assuming “continuum-Pollak” preferences, the model allows for consistent aggregation over a continuum of sectors, in each of which a...

To many economists the public's support for the minimum wage (MW) institution is puzzling, since the MW is considered a “blunt instrument” for redistribution. To delve deeper in this issue we build models in which workers are heterogeneous in ability. In the first model, the government does...

We show that dealers' limited market participation, coupled with an informational friction resulting from lack of market transparency, can make liquidity demand upward sloping, inducing strategic complementarities: traders demand more liquidity when the market becomes less liquid, fostering...

We develop a macroeconomic framework in which firms are large and have market power with respect to both products and labor. Each firm maximizes a share-weighted average of shareholder utilities, which makes the equilibrium independent of price normalization. In a one-sector economy, if returns...

This paper considers cost-reducing R&D investment with spillovers in a Cournot oligopoly with overlapping ownership. We show that overlapping ownership leads to internalization of rivals' profits by firms and find that, for demand not too convex, increases in overlapping ownership increase...

Using an intertemporal model of saving and capital accumulation we demonstrate that it is impossible for any binding minimum wage to increase the after-tax incomes of workers if the production function is Cobb-Douglas with constant returns to scale, or if there are no differences in ability...

This paper studies the aggregate and distributional implications of introducing tuition fees for public education services into a tax system with income and consumption taxes. The setup is a neoclassical growth model where agents differ in capital holdings. We show that the introduction of...
