I study the effect of fatigue and innate ability on performance in a model with incomplete contracts, lumpy tasks requiring multiple periods of work and stochastic productivity shocks. I find that increasing ability or reducing fatigue does not lead necessarily to more productive efficiency,...

The standard approach to modelling consumption/saving problems is to assume that the decisionmaker is solving a dynamic stochastic optimization problem However under realistic descriptions of utility and uncertainty the optimal consumption/saving decision is so difficult that only recently...

A network market is a market in which the benefit each consumer derives from a good is an increasing function of the number of consumers who own the same or similar goods. A major obstacle that plagues the introduction of a network good is the ability to reach critical mass, namely, the minimum...

This paper studies the location decisions of Swedish start-up independent schools. It makes use of the great expansion of independent schools following a reform implemented in 1992 to test what local market characteristics are correlated with independent school entry. The results suggest that...

This paper studies the optimal design of dynamic research contests. We introduce interim transfers, which are paid in every period while the contest is ongoing, to an otherwise standard setting. We show that a contest where: (i) the principal can stop the contest in any period, (ii) a constant...

This paper considers the optimal design of dynamic research contests when the buyer can set time-dependent prizes. We derive the buyer-optimal contest and show that it entails an increasing prize schedule. Remarkably, this allows the buyer to implement a global stopping rule. In particular, the...

The effect of a general school choice reform on student performance is studied in a Swedish institutional setting. A rich set of individual level data allows estimation of a value added specification, mitigating problems with omission of relevant variables. Increased school competition is shown...

The Inflation Reduction Act (IRA), passed under the Biden administration in August 2022, is the biggest US climate bill to date. Its focus on subsidy-driven decarbonization incentives marks a potential turning point in US industrial policy and might prevent its repeal under the upcoming Trump...

I study the effect of an innovation subsidy on the growth of firms in a developing country. Using administrative microdata for Brazil and difference-in-differences, I find that innovation subsidies drive firm growth by facilitating firm entry into high-tariff markets with domestically produced,...

We argue that the US trade and industry sector has experienced several unsustainable sectoral processes, including (i) a fall in the trade balance in machinery and equipment and high-tech (HT) industries, (ii) a rise in import multipliers in machinery and equipment and HT industries, (iii) a...
