Profitability of Fertilizer: Experimental Evidence from Female Rice Farmers in Mali
Beaman, Lori; Karlan, Dean; Thuysbaert, Bram; Udry, … - In: American Economic Review 103 (2013) 3, pp. 381-86
We conducted an experiment providing fertilizer grants to female rice farmers in Mali. We found that women who received fertilizer used both more fertilizer and more complementary inputs such as herbicides and hired labor. This shows that farmers respond to an increase in one input by...

The Effect of the TseTse Fly on African Development
Alsan, Marcella - In: American Economic Review 105 (2015) 1, pp. 382-410
The TseTse fly is unique to Africa and transmits a parasite harmful to humans and lethal to livestock. This paper tests the hypothesis that the TseTse reduced the ability of Africans to generate an agricultural surplus historically. Ethnic groups inhabiting TseTse-suitable areas were less likely...

Acemoglu, Daron; Ozdaglar, Asuman; Tahbaz-Salehi, Alireza - In: American Economic Review 105 (2015) 2, pp. 564-608

Stability in Supply Chain Networks
Ostrovsky, Michael - In: American Economic Review 98 (2008) 3, pp. 897-923
This paper studies matching in vertical networks, generalizing the theory of matching in two-sided markets. It gives … sufficient conditions for the existence of stable networks and presents an algorithm for finding two of them. One is the best …. The paper describes several properties of the set of stable networks and discusses applications of the theory to the …

All-or-Nothing Monitoring
Zhao, Rui R. - In: American Economic Review 98 (2008) 4, pp. 1619-28
A principal can observe both the output and input of an agent who works at a job involving multiple tasks. We provide a simple theory that explains why it may be optimal for the principal to use only an output-based incentive contract, even though the principal can monitor the agent's actions...

Partnerships versus Corporations: Moral Hazard, Sorting, and Ownership Structure
Kaya, Ayca; Vereshchagina, Galina - In: American Economic Review 104 (2014) 1, pp. 291-307
Team production takes advantage of technological complementarities but comes with the cost of free-ridership. When workers differ in skills, the choice of sorting pattern may be associated with a nontrivial trade-off between exploiting the technological complementarities and minimizing the cost...
