We introduce public capital and public services as inputs in an endogenous growth model. We show that the growth rate depends on the apportionment of tax revenues between the accumulation of public capital and the provision of public services. When public spending is financed by proportional...

Several leading undergraduate intermediate macroeconomics textbooks now include a simple reduced-form New Keynesian model of short-run dynamics (alongside the IS-LM model). Unfortunately, there is no accompanying description of how the zero lower bound on nominal interest rates affects the...

This paper presents a model of international trade in goods that are ranked by quality. The model differs from existing theories of trade under vertical product differentiation in several ways. The main difference is in the way quality is modeled. But this paper also has different positive...

In this endogenous growth model, a minimum efficient scale of production and workers' home-to-work travel costs combine to give firms monopsony power, and this monopsony power leads to slower growth. Monopsony drives the wage below the marginal product of labor. This lower wage leads to lower...

The role of fiscal policy is examined when public goods provide both productive and utility services. In the presence of congestion, the consumption tax is shown to be distortionary. Optimal fiscal policy involves using consumption-based instruments in conjunction with the income tax. An income...

We revisit the relationship between financial development and economic growth in a panel of 52 middle-income countries over the 1980–2008 period. Using pooled mean group estimations in a dynamic heterogeneous panel setting, we show that there is an inverted U-shaped relationship between...
