We show that after the revelation of corporate fraud in a state, the equity holdings of households in that state decrease significantly both in the extensive and the intensive margins. Using an exogenous shock to fraud detection and exogenous variation in households’ lifetime experiences of...

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...

We study ffort and risk-taking behaviour in an economy with a continuum of principal-agent pairs where each agent exerts costly hidden effort. When the industry productivity is uncertain, agents have motivations to match the industry average effort, which results in contractual externalities....

Africa’s recent growth performance has raised expectations of a bright economic future for the continent after decades of decline. Yet there is a genuine question about whether Africa’s growth can be sustained, and if so, at what level. The balance of the evidence suggests caution on the...

This chapter describes how the spatial distribution of economic activity changes as economies develop and grow. We start with the relation between development and rural-urban migration. Moving beyond the coarse rural-urban distinction, we then focus on the continuum of locations in an economy...

What is so special about banks that their demise often triggers government intervention? In this paper we show that, even ignoring interconnectedness issues, the failure of a bank causes a larger welfare loss than the failure of other institutions. The reason is that agents in need of liquidity...

How do frictions in price setting influence monetary non-neutrality? We revisit this classic question in a quantitative menu cost model with multi-product firms that face idiosyncratic shocks with unsynchronized stochastic volatility. The model matches the unconditional distribution of price...

In this paper, we investigate the use of interactive effect or linear factor models in regional policy evaluation. We contrast treatment effect estimates obtained by Bai (2009)'s least squares method with the popular difference in differences estimates as well as with estimates obtained using...

We develop a dynamic model of liquidity provision, in which hedgers can trade multiple risky assets with arbitrageurs. We compute the equilibrium in closed form when arbitrageurs' utility over consumption is logarithmic or risk-neutral with a non-negativity constraint. Liquidity is increasing in...

Climate change must deal with two market failures, global warming and learning by doing in renewable use. The social optimum requires an aggressive renewables subsidy in the near term and a gradually rising carbon tax which falls in long run. As a result, more renewables are used relative to...
