Student employment subsidies are one of the largest types of federal employment subsidies, and one of the oldest forms of student aid. Yet it is unclear whether they help or harm students' long term outcomes. We present a framework that decomposes overall effects into a weighted average of...

We show that credit crises can be Self-Confirming Equilibria (SCE), which provides a new rationale for policy interventions like, for example, the FRB's TALF credit-easing program in 2009. We introduce SCE in competitive credit markets with directed search. These markets are efficient when...

Using commodity futures contract and spot prices, we estimate the incidence of the US ethanol subsidy accruing to corn farmers, ethanol producers, gasoline blenders, and gasoline consumers at expiration in 2011. We find compelling evidence that ethanol producers captured two-thirds of the...

Dynamically and statically optimal Pigouvian subsidies on durables will differ in a growing economy. For durables with positive externalities, such as sanitation, statically optimal subsidies will typically grow. However, in a dynamic game, governments can most cheaply induce optimal purchasing...

Cities generate negative, as well as positive, externalities; addressing those externalities requires both infrastructure and institutions. Providing clean water and removing refuse requires water and sewer pipes, but the urban poor are often unwilling to pay for the costs of that piping....

The paper studies the effects of tax policy on venture capital activity. Entrepreneurs pursue a single high risk project each but have no own resources. Financiers provide equity finance. They must structure the entrepreneur's profit share and base salary to assure their incentives for full...

The covid-19 crisis has led to a sharp deterioration in firm and bank balance sheets. The government has responded with a massive intervention in corporate credit markets. We study equilibrium dynamics of macroeconomic quantities and prices, and how they are affected by government policy. The...

We evaluate multiple variants of a commonly used intervention to boost education in developing countries -- the conditional cash transfer (CCT) -- with a student level randomization that allows us to generate intra-family and peer-network variation. We test three treatments: a basic CCT...

We analyze by far the most extensive data base yet employed in estimating capitalizationquot; of below-market interest rates into asset prices: nearly 300,000 sales of owner-occupied homes inquot; Sweden from 1981 to 1993 with 40,000 including government subsidized interest rates. Ourquot;...

Public-private partnerships (PPPs) cannot be justified because they free public funds. When PPPs are justified on efficiency grounds, the contract that optimally balances demand risk, user-fee distortions and the opportunity cost of public funds, features a minimum revenue guarantee and a...
