The G-8 Multilateral Debt Relief Initiative (MDRI) is the next step of the Highly Indebted Poor Countries Initiative (HIPC). There are two reasons why MDRI is unlikely to help poor countries. First, the amount of money at stake is trivial. The roughly $2 billion of annual debt payments to be...

Joseph Schumpeter argued in Capitalism, Socialism and Democracy that the rise of large firms%u2019 investments in in-house R&D spelled the doom of the entrepreneurial innovator. We explore this idea by analyzing the career patterns of successive cohorts of highly productive inventors from the...

We use a variant of the Implicit Association Test (IAT) to examine individuals’ implicit attitudes towards various ethnic groups. Using a population from the Democratic Republic of Congo, we find that the IAT measures show evidence of an implicit bias in favor of one’s own ethnicity....

It is widely hypothesized that incomes in wealthy countries are insulated from environmental conditions because individuals have the resources needed to adapt to their environment. We test this idea in the wealthiest economy in human history. Using within-county variation in weather, we estimate...

We review both the theoretical and empirical literature on entrepreneurship and financial frictions, with an emphasis on the heterogeneous and dynamic micro-level implications of financial frictions for macro development.

In France, firms with 50 employees or more face substantially more regulation than firms with less than 50. As a result, the size distribution of firms is visibly distorted: there are many firms with exactly 49 employees. We model the regulation as the combination of a sunk cost that must be...

Hunger during pre-harvest lean seasons is widespread in the agrarian areas of Asia and Sub-Saharan Africa. We randomly assign an $8.50 incentive to households in rural Bangladesh to temporarily out-migrate during the lean season. The incentive induces 22% of households to send a seasonal...

We examine the channels through which a randomized early childhood intervention in Colombia led to significant gains in cognitive and socio-emotional skills among a sample of disadvantaged children. We estimate production functions for cognitive and socio-emotional skills as a function of...

Heterogeneously risk-averse individuals who lack access to formal insurance build and use relationships with each other to manage risk. I show that the composition of equilibrium relationships under pairwise matching and when group size is endogenous is determined by a mean-variance trade-off...
