What are the micro and macro implications of a credit crunch? We study this question in a model where heterogeneous entrepreneurs can finance their investment by borrowing subject to collateral constraints and/or by using internal funds. We discipline our theory by requiring that the size...

Individuals are born into families that differ in size and managerial skill endowment. Each member of a family has the option to (i) work as a manager in the family firm; (ii) work as a manger in a non-family firm; or (iii) supply non-managerial labor for a wage. We consider two alternative...

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

What are the effects of a large temporary shock to the economy such as a temporary lockdown in response to a pandemic? Are the effects propagated and made persistent by firms' deteriorating balance sheets and labor market frictions? This paper develops a model with financial market and labor...

Why don't poor countries adopt more productive technologies? Is there a role for policies that coordinate technology adoption? To answer these questions, we develop a quantitative model that features complementarity in firms' technology adoption decisions: The gains from adoption are larger when...

What are the effects of a temporary lockdown of the economy? Do firms' deteriorating balance sheets and labor market frictions propagate and prolong the effects? We answer these questions in a model with financial and labor market frictions. The model makes quantitative predictions about the...

Why are financial crises associated with a sustained rise in unemployment? We develop a tractable model with frictions in both credit and labor markets to study the aggregate and micro-level implications of a credit crunch—i.e., a sudden tightening of collateral constraints. When we simulate a...

We review the empirical evidence on microfinance and asset grants to the ultra poor or microentrepreneurs, and assess our ability to account for this evidence using quantitative theory. Properly executed, these interventions can help segments of the population increase their income and...
