Conformal prediction methods are statistical tools designed to quantify uncertainty and generate predictive sets with guaranteed coverage probabilities. This work introduces an innovative refinement to these methods for classification tasks, specifically tailored for scenarios where multiple...

We study innovation and ideas generation in bureaucracies, combining qualitative and quantitative evidence on workplace cultures, workplace climate and bureaucratic performance. We study these issues at-scale in a developing country, using data from bureaucrats in all ministries staffed by the...

Assume that one is interested in estimating an average treatment effect (ATE), equal to a weighted average of S conditional average treatment effects (CATEs). One has unbiased estimators of the CATEs. One could just average the CATE estimators, to form an unbiased estimator of the ATE. However,...

We use data on individual expectations from the Survey of Professional Forecasters and Blue Chips, and document a few novel empirical facts that cannot be reconciled with the Rational Expectations hypothesis. We argue that a simple model where agents are unaware of (at least some) supply shocks and...

The range of animal practices potentially classified as medical varies widely both functionally and mechanistically, and there is no agreed upon definition of medicine that can help determine which cases ought to count as such. In this paper, we argue that all available definitions are fatally...

We develop a model to study the pricing and welfare implications of recom- mender platforms—i.e., platforms that provide recommendations about products that match a consumer’s preference. Sellers decide whether to be active on the platform, and consumers can buy via seller’s direct channel or via...

We develop a spatial model of climate risks when goods markets across regions are economically integrated but firms can only insure against local climate shocks. We show that firms’ insurance demands across regions can be strategic complements or substitutes depending on the correlation of climate...

Improving agricultural productivity is vital to anti-poverty and food security goals but can have ecological ramifications. Increasing the relative value of agricultural land may spur deforestation, but factor market constraints paired with improvements in existing land productivity may reduce the...

In principle, a ‘natural' monopoly exists when a single firm has the lowest cost structure for production. This paper shows that a paradox arises for certain infrastructure and delivery products that satisfy a widely accepted technical definition for such monopolies. Under well-specified conditions...
