Protectionism enjoys surprising popular support, in spite of deadweight losses. At the same time, trade barriers appear to decline with public information about protection. This paper develops an electoral model with heterogeneously informed voters which explains both facts and predicts the...

I provide a justification of intellectual property rights as a source of static efficiency gains in manufacturing, rather than dynamic benefits from greater innovation. I develop a property-rights model of a supply relationship with two dimensions of non-contractible investment. In equilibrium,...

We present a tractable stochastic endogenous growth model that explains how social capital influences economic development. In our model, social capital increases citizens' awareness of government activity. Hence, it alleviates the electoral incentives to under- invest in education, whose...

In a model where biased judges can distort contract enforcement, we uncover positive feedback effects between the use of innovative contracts and legal evolution that improve verifiability and contracting over time. We find, however, that the cost of judicial bias also grows over time because...

Why do public-sector workers receive so much of their compensation in the form of pensions and other benefits? This paper presents a political economy model in which politicians compete for taxpayers' ’and government employees' votes by promising compensation packages, but some voters cannot...

Many metropolitan areas have experienced extreme boom-bust cycles over the past century. Some places, like Detroit, grew enormously as industrial powerhouses and then declined, while other older cities, like Boston, seem quite resilient. Education does a reasonable job of explaining urban...

Economists understand protectionism as a costly mechanism to redistribute from the average citizen to special-interest groups; yet political platforms that deviate from free trade have surprising popular appeal. I present an explanation based on heterogeneous information across citizens whose...

The classic theory of fiscal federalism suggests that different people should have different governments. Yet, separate local governments with homogeneous constituents often end up doing poorly. This paper explains why and answers three questions: when regions are heterogeneous, what determines...

We study the equilibrium determinants of firm-level heterogeneity in a model in which firms can choose between different probability distributions when drawing productivity at the entry stage and explore the implications in closed and open economy. One novel result is that export opportunities,...

We study the incentives to improve ability in a model where heterogeneous firms and workers interact in a labor market characterized by matching frictions and costly screening. When effort in improving ability raises both the mean and the variance of the resulting ability distribution, multiple...
