June 2015Time-Inconsistency and Saving: Experimental Evidence from Low-Income Tax Filers
with Damon Jones: w21272
We conduct a field experiment designed to test theories of time-inconsistency, namely a "Beta-Delta" model of present bias. The experiment takes place in the context of a saving decision made by low-income tax filers who can deposit their income tax refund into an illiquid account. We find qualitative evidence consistent with present-biased preferences. The tradeoff between an earlier payment or a later one is much more skewed toward taking the early payment when the decision is made on the spot than when the decision is made in advance. We estimate a β and δ of 0.34 and 1.08 over an 8-month horizon, respectively, which translates into an annual discount rate of 164%.
January 2011Does Management Matter? Evidence from India
with Nicholas Bloom, Benn Eifert, David McKenzie, John Roberts: w16658
A long-standing question in social science is to what extent differences in management cause differences in firm performance. To investigate this we ran a management field experiment on large Indian textile firms. We provided free consulting on modern management practices to a randomly chosen set of treatment plants and compared their performance to the control plants. We find that adopting these management practices had three main effects. First, it raised average productivity by 11% through improved quality and efficiency and reduced inventory. Second, it increased decentralization of decision making, as better information flow enabled owners to delegate more decisions to middle managers. Third, it increased the use of computers, necessitated by the data collection and analysis involved ...
