|March 2018||Making Moves Matter: Experimental Evidence on Incentivizing Bureaucrats through Performance-Based Postings|
with Adnan Q. Khan, Benjamin A. Olken: w24383
Bureaucracies often post staff to better or worse locations, ostensibly to provide incentives. Yet we know little about whether this works, with heterogeneity in preferences over postings impacting effectiveness. We propose a performance-ranked serial dictatorship mechanism, whereby bureaucrats sequentially choose desired locations in order of performance. We evaluate this using a two-year field experiment with 525 property tax inspectors in Pakistan. The mechanism increases annual tax revenue growth by 30-41 percent. Inspectors that our model predicts face high equilibrium incentives under the scheme indeed increase performance more. Our results highlight the potential of periodic merit-based postings in enhancing bureaucratic performance.
|October 2014||Tax Farming Redux: Experimental Evidence on Performance Pay for Tax Collectors|
with Adnan Q. Khan, Benjamin A. Olken: w20627
Performance pay for tax collectors has the potential to raise revenues, but might come at a cost if taxpayers face undue pressure from collectors. We report the first large-scale field experiment on these issues, where we experimentally allocated 482 property tax units in Punjab, Pakistan into one of three performance-pay schemes or a control. After two years, incentivized units had 9.3 log points higher revenue than controls, which translates to a 46 percent higher growth rate. The scheme that rewarded purely on revenue did best, increasing revenue by 12.8 log points (62 percent higher growth rate), with little penalty for customer satisfaction and assessment accuracy compared to the two other schemes that explicitly also rewarded these dimensions. Further analysis reveals that these reve...

|August 2009||Screening Peers Softly: Inferring the Quality of Small Borrowers|
with Rajkamal Iyer, Erzo F.P. Luttmer, Kelly Shue: w15242
The recent banking crisis highlights the challenges faced in credit intermediation. New online peer-to-peer lending markets offer opportunities to examine lending models that primarily cater to small borrowers and that generate more types of information on which to screen. This paper evaluates screening in a peer-to-peer market where lenders observe both standard financial information and soft, or nonstandard, information about borrower quality. Our methodology takes advantage of the fact that while lenders do not observe a borrower's exact credit score, we do. We find that lenders are able to predict default with 45% greater accuracy than what is achievable based on just the borrower's credit score, the traditional measure of creditworthiness used by banks. We further find that lenders ef...

|October 2006||Tracing the Impact of Bank Liquidity Shocks: Evidence from an Emerging Market|
with Atif Mian: w12612
Do liquidity shocks matter? While even a simple `yes' or `no' presents identification challenges, going beyond this entails tracing how such shocks to lenders are passed on to borrowers, and whether borrowers can in turn cushion these shocks through the credit market. This paper does so by using data that follows all loans made by lenders to borrowing firms in Pakistan, and exploiting cross-bank variation in liquidity shocks induced by the unanticipated nuclear tests in 1998. We isolate the causal impact of the bank lending channel by showing that for the same firm borrowing from two different banks, its loan from the bank experiencing a 1% larger decline in liquidity drops by an additional 0.6%. The liquidity shock also lowers the probability of continued lending to old clients and extend...
