Two for-profit Philippine social enterprises, aiming to demonstrate corporate social responsibility by increasing microlending to the poor, incorporated a widely-used poverty measurement tool into their loan applications and tested the tool using randomized training content. Treated loan...

A vast theoretical literature shows that inefficient market structures may arise in free entry equilibria. The inefficiency may manifest itself in the number, variety, or quality of products. Previous empirical work demonstrated that excessive entry may obtain in local radio markets. Our paper...

Commercial radio stations and advertisers have potentially conflicting interests about when commercial breaks should be played. This paper estimates an incomplete information timing game to examine stations' equilibrium timing incentives. It shows how identification can be aided by the existence...

Free entry into markets with decreasing average costs and differentiated products can result in an inefficient number of firms and suboptimal product variety. Because new firms and products draw their customers in part from existing products, concentration can affect incentives to enter as well...

Radio signals are pure public goods whose total value to society is the sum of their value to advertisers and listeners. Because broadcasters can capture only part of the value of their product as revenue, there is the potential for a classic problem of underprovision. Small markets have much...

Worldwide, extreme poverty is often concentrated in spaces where people and property are not safe enough to sustain effective markets, and where development assistance is dangerous - and might even induce violence. Expanding governance by coercively taking control of territory may enable markets...

This paper investigates the biological standard of living toward the end of Spanish rule. We investigate levels, trends, and determinants of physical stature from the birth cohorts of the 1860s to the 1890s using data on 23,000 Filipino soldiers enlisted by the U.S. military between 1901 and...

We develop a micro-founded general equilibrium model with heterogeneous agents and three dimensions of financial inclusion: access (determined by a participation cost), depth (determined by a borrowing constraint), and intermediation efficiency (determined by a monitoring cost). We find that the...
