“An Empirical Model of Price Transparency and Markups in Health Care”
Abstract: In the market for health care services, consumers often do not know exact
prices when choosing where to receive care. This makes it difficult to shop around for
low cost options, potentially reducing effective consumer price elasticity and leading to
higher prices. This paper introduces an empirical model that explicitly accounts for the
lack of price transparency. First, I develop a demand model that separates underlying
consumer preferences from uncertainty about prices. Identification comes from plausibly
exogenous variation in consumers' information set due to the introduction of a publiclyavailable website providing price information for a subset of medical procedures. I then
combine this with a model of bargaining between medical providers and insurers in order
to examine how price transparency affects negotiated prices in equilibrium. I estimate the
model using detailed administrative data on medical imaging claims and website usage
and show that price transparency reduces health care prices if a large fraction of
consumers are informed. Counterfactual simulations imply that if all consumers were
informed, equilibrium prices would be 19 percent lower.

JOB MARKET PAPER
“Credit Scoring Meets Small Agricultural Lending: Exogenous Shocks, Recovery and Access to Formal Credit”
Abstract: Credit histories and credit scoring have become a widespread tool to assess the creditworthiness
of prospective borrowers, and have been found to increase efficiency and welfare. But this paper identifies a
market failure resulting from their use in small scale agricultural lending in developing countries. Farmers’
scores – and their access to credit – decline because of exogenous short-term weather shocks that arguably
do not reduce their likelihood of future repayment. I use data on the near universe of formal agricultural
loans for coffee production in the country of Colombia to show that excessive rainfall shocks cause lower loan
repayment, lower credit scores, and more frequent denial of subsequent loan applications. Further, drawing
on the agronomic literature on coffee production and using survey data, I show that the coffee productivity
and income recover faster from these shocks than farmers’ credit histories. I present evidence of repayment
recovery in a sample of long term loans and in a sample of high ex-ante credit score borrowers, consistent
with the results on income recovery. This leads to costs for the farmers and the lender that could be avoided.
Credit scoring should incorporate individual-level weather information, which would account for the more
volatile nature of income of small scale agricultural production in developing countries.

Job Market Paper: “Affirmative Action, Caste and the Marriage Market”
Abstract: This study investigates the role of a strong social norm - caste - on the marriage market
in India and how it responds to economic changes. A jobs-based affirmative action policy, the
implementation of the Mandal Commission report in December 1993, differentially affects
incomes across cohorts for treated castes. This is used to separately identify the effects of caste
and income on marital partner choice and the distribution of the match surplus using a
difference-in-differences strategy. The affirmative action policy is found to have an asymmetric
effect across genders - male members of the treated group are found to attract more desirable
spouses and get a higher share of the marital match surplus while there is no similar effect for
women. A structural model of the marriage market based on Choo & Siow(2006) is used to
investigate the marital welfare effects of the policy while controlling for selection effects.
Similar results are found. These findings suggest that the marriage market and intra household
decision making plays a significant role in determining the distribution of welfare changes from
economic shocks.

Job Market Paper: “Estimating Cost Functions in Perceptual and Cognitive Processes” (with
Nathaniel Neligh)
Abstract: In models of rational inattention, information costs are usually modeled using
mutual information, which measures the expected reduction in entropy between prior and
posterior beliefs, or ad hoc functional forms, but little is known about what form these
costs take in reality. We show that under mild assumptions on information cost functions,
including continuity and convexity, gross payoffs to decision makers are non-decreasing
and continuous in potential rewards. We conduct laboratory and online experiments,
consisting of simple perceptual tasks with fine-grained variation in the level of potential
rewards, that allow us to test several hypotheses about rational inattention and compare
various models of information costs via information criteria. We find that most subjects
exhibit monotonicity in performance with respect to potential rewards, and there is mixed
evidence on continuity and convexity of costs. Moreover, a significant portion of subjects
are likelier to make small mistakes than large ones, contrary to the predictions of mutual
information. This suggests that while people are generally rationally inattentive, their cost
functions may display non-convexities or discontinuities, or they may incorporate some
notion of perceptual distance, which has implications for various economic applications,
including consumer choice.

Job Market Paper: A Kinked-Demand Theory of Price Rigidity
I provide a microfounded theory for one of the oldest, but so far informal, explanations of price
rigidity: the kinked demand curve theory. Assuming that some customers observe at no cost only
the price of the store they happen to be at gives rise to a kink in firms' demand curves: a price
increase above the market price repels more customers than a price decrease attracts. The kink in
turn makes a range of prices consistent with equilibrium, but an intuitive criterion---the adaptive
rational-expectations criterion---selects a unique equilibrium where prices stay constant for long.
The kinked-demand theory is consistent with price-setters' account of price-rigidity as arising
from the customer's---not the firm's---side, contrary to prominent models of price rigidity. The
kinked-demand theory can be tested against menu-cost models in micro data: it predicts that
prices should be more likely to change if they have recently changed, and that prices should be
more flexible in markets where customers can more easily compare prices. The kinked-demand
theory has novel implications for monetary policy: its Phillips curve is strongly convex but does
not contain any (present or past) expectations of inflation; its long-run Phillips curve is
essentially similar as its short-run Phillips curve, leading to a long-run trade-off between output
and inflation; and changes to the distribution of sectoral productivity such as oil price shocks
shift the Phillips curve.

“Asymmetric Information and the Link Between Leverage and Mortgage Default”
Abstract:
Borrowers with large mortgages relative to the value of their homes default at higher rates. This
paper asks whether this correlation is due to moral hazard—larger balances causing borrowers to
default—or adverse selection—ex-ante risky borrowers choosing larger loans. To separate these
information asymmetries I exploit plausibly exogenous variation in borrowers' ex-post balances
generated by (i) the unique contract structure of Option Adjustable Rate Mortgages and (ii) the
unexpected divergence of the financial indices used determine interest rate adjustments during the
2008 crisis. I find strong evidence of moral hazard: a 10 point increase in a borrower's loan-to-value
ratio causes a 16 percent increase in the one year default rate. However, adverse selection also
explains 30-40 percent of the baseline correlation between leverage and default. I construct and
simulate a simple model of mortgage choice and default to highlight the policy tradeoff informed by
the separation of these asymmetries. Optimal regulation of mortgage leverage must balance losses
from foreclosures against under-provision of credit due to adverse selection.

Job Market Paper: “Trade and Real Incomes of the Rich and Poor: Cross-Country Evidence”
(with Feiran Zhang)
Abstract: What is the impact of trade on the distribution of real income, 𝑤! /𝑝! , in a large crosssection of countries? The vast majority of the literature focuses on the effect of trade on the
distribution of nominal incomes, 𝑤! . A small number of studies consider its differential impact
on the consumer price indices, 𝑝! . Results tend to go in opposite directions. We build a model
embedding demand heterogeneity across consumers in an assignment framework with many
labor groups to quantify the distributional effects of trade for a wide range of countries taking
both channels into account. We find that as a result of a five percent reduction in all bilateral
trade costs, the bigger decline in the consumer price indices facing the poor more than
compensates for their smaller nominal income gains (or larger nominal income losses). More
specifically, in the average country, real income of the bottom 10th percentile increases by 0.8%
more than the top 10th percentile. In addition, the poor in high-income countries benefit more
from the reduction in consumer price indices, and the rich in high-income countries benefit more
from the increase in nominal incomes. We also find that there is an interaction between the two
channels. Our results highlight the importance of combining both the income and the expenditure
channels in order to measure the distributional effects of trade accurately.

Job Market Paper: "Lobbying for International Protection of Intellectual Property Rights"
Abstract:
Lobbying has been thoroughly analyzed in the context of trade protection, but there is a
gap in the literature when it comes to lobbying for intellectual property right (IPR). I
propose a model that analyzes the effect of firm lobbying for IPR protection in
innovatively driven economies in an international setting. In particular, I compare the
outcomes for the IPR protection level and global social welfare between a world that is
not cooperating on IPR and a world with cooperation and IPR-related trade agreements,
such as the TRIPS, TPP and TTIP. I show that lobbying necessarily leads to inefficient
international agreements resulting in too much IPR protection and under some
circumstances could be even worse than when countries don't cooperate at all. I also
show that international lobbying and high concentration of capital can further exacerbate
this outcome. The model generates predictions consistent with firm-level lobbying data.

“How Do Hospitals Respond to Managed Care? Evidence from At-Risk Newborns”
Abstract: Despite its widespread adoption, there is little evidence that Medicaid Managed Care (MMC)
reduces costs without compromising health outcomes. I exploit an arbitrary component of MMC
enrollment in New York to examine hospital responses and newborn health outcomes. During the study
period, infants weighing less than 1,200 grams (2 pounds, 10 ounces) were excluded from MMC and
were instead served through the traditional fee-for-service (FFS) system. Using a regression discontinuity
design, I find that newborns enrolled in MMC due to the policy stayed fewer days in the hospital and
thereby had less expensive neonatal visits. The cost differences are driven by birth hospitals retaining
more newborns enrolled in FFS while transferring away those enrolled in MMC. I find that MMC had
little impact on newborn health measured by in-hospital mortality and hospital readmission. Hospitals
only engaged in these behaviors when a high-quality hospital was nearby, suggesting that hospitals did
not sacrifice quality of care for cost reductions.

Job Market Paper: “Simultaneous Spatial Panel Data Models with Common Shocks”
Abstract: I consider a simultaneous spatial panel data model, jointly modeling three effects: spatial
effect, common shocks effect and simultaneous effect. The joint modeling and consideration of
cross-sectional heteroscedasticity result in a large number of incidental parameters. I propose two
estimation approaches, the quasi maximum likelihood (QML) method and an iterative generalized
principal components (IGPC) method. I develop a full inferential theory for the two estimation
approaches, and study the trade-off between model specification and their respective asymptotic
performances. I further investigate the finite sample performance of both methods using Monte
Carlo simulations, and find that both methods perform well and simulation results corroborate the
inferential theories. Some extensions of the model are considered. Finally, I apply the model to
analyze how monetary policy shocks impact firm's bond and stock prices through the production
network with the existence of simultaneous effects between the two assets.

Job market paper: “Firm Organization, Chinese Imports, and U.S. Manufacturing Employment”
Abstract What is the impact of Chinese imports on employment in US manufacturing firms? Previous papers
have found a negative effect of Chinese import competition on employment in US manufacturing
establishments, industries, and regions. However, I show theoretically and empirically that the impact of
offshoring on firms (which can be thought of as collections of establishments) can be different from that on
individual establishments because offshoring reduces costs at the firm-level. These cost reductions can result
in firms expanding their total manufacturing employment even as particular establishments are shrunk. Using
novel data from the US Census Bureau, I show that the data supports this view: US firms expanded
manufacturing employment in response to increased Chinese import competition, in both US output and input
markets, as they re-organized towards less exposed industries. More exposed firms expanded employment of
high-skilled (i) by hiring more production workers in manufacturing whom they paid higher wages, and (ii) in
services complementary with high-skilled and high-tech manufacturing such as R&D, design, engineering,
headquarter services. In other words, although Chinese imports may have reduced employment within some
establishments, these losses were more than offset by gains in employment within the same firms. Contrary to
the conventional wisdom, firms exposed to greater Chinese imports created more manufacturing and nonmanufacturing jobs than those not exposed.

Job Market Paper: “Assortative Matching and Complementarities in College Markets”
Abstract: This paper examines one type of assortative matching in college markets:
students with high socioeconomic status (SES) are more likely to attend high quality
colleges. Assortativity matters if SES and college quality are complementary educational
inputs. I develop an econometric framework that provides tests for the existence and sign
of this complementarity. I implement these tests by exploiting a 2000 reform of the
national college admission exam in Colombia, which caused a market-wide reduction in
assortative matching in some regions of the country. I find that the reform lowered
average graduation rates and post-college earnings in affected regions, consistent with a
positive complementarity between SES and college quality. I also find evidence of
mismatch: part of these negative effects came from the low SES students who were
shifted into higher quality colleges. However, both the market-wide and mismatch effects
die out several cohorts after the exam reform, which suggests that student/college
complementarities are not set in stone.

“Rural Road Infrastructure & Agricultural Production: Evidence from India”
Abstract: This paper estimates the role of improvements in infrastructure on households' crop choice and
input use in agriculture. The Central Government of India launched a large-scale rural road-building
program in 2000, targeting villages that lacked all-weather connectivity. Strict guidelines governed
eligibility and timing of program road provision, with larger villages receiving roads before smaller
villages. I exploit the precise timing of road construction as a source of exogenous variation in
connectivity using a household-level panel in a difference-in-difference framework. I find that households
who gain access to improved road infrastructure diversify their crop mix — they increasingly cultivate
commercial, non-cereal crops. Households also significantly increase take up of productivity-enhancing
agricultural technologies such as high-yielding variety seeds, chemical fertilizers and irrigation. These
gains are concentrated among small-scale cultivators. I find evidence that these effects operate through an
increase in access to input markets, an increase in labor mobility as well as an increase in access to
product markets where farm output is sold. These findings emphasize the substantial barrier to productive
investments generated by poor infrastructure that hampers access to markets.

“The Morale Effects of Pay Inequality” (with Emily Breza and Supreet Kaur). NBER Working Paper No.
22491. Revise and Resubmit, Quarterly Journal of Economics.
Abstract: The idea that worker utility is affected by co-worker wages has potentially broad labor market
implications. In a month-long experiment with Indian manufacturing workers, we randomize whether coworkers within production units receive the same flat daily wage or different wages (according to baseline
productivity rank). For a given absolute wage, pay inequality reduces output and attendance by 0.24
standard deviations and 12%, respectively. These effects strengthen in later weeks. Pay disparity also
lowers co-workers’ ability to cooperate in their self-interest. However, when workers can clearly observe
productivity differences, pay inequality has no discernible effect on output, attendance, or group
cohesion.
Research in Progress:
“Testing for Labor Rationing: Revealed Preference Estimates from Demand Shocks” (with Emily Breza
and Supreet Kaur)
Abstract: In this project, we develop a revealed preference approach to test for and quantify labor
rationing in rural Indian labor markets. We exploit a field experiment in which large numbers of rural
workers are recruited for factory employment for a one-month period during the agricultural lean season.
This generates transitory aggregate labor demand shocks in a random set of villages, absorbing up to 30%
of the labor force of casual daily workers. If a large fraction of workers is removed from a village, then
the following sets of effects will be consistent with a level of labor rationing that is at least as large as the
size of the demand shock: i) no effect on the local village wage, ii) no effect on the level of aggregate
wage employment in the village; and iii) positive employment spillovers—higher individual employment
and lower reported involuntary unemployment—on the laborers who remain in the village (i.e. who are
not removed). Pilot results from 36 villages provide evidence in support of these predictions. The large
demand shocks had no discernible effect on local wages. However, they did generate substantial
employment spillovers—workers who remained in treatment villages experienced a 37% increase in
average employment relative to workers in control villages.

“The Puzzle of Mistaken Millions: The MTA Surcharge and the Surge of Money onto MetroCards” under
review
Abstract: Since 1998, the New York City Metropolitan Transportation Authority (MTA) system has used prepaid cards (MetroCards) to collect subway and bus fares. In 2013, the MTA imposed a $1 card fee (surcharge)
on new MetroCard purchases. After the card fee was imposed, riders started to put more money on new
MetroCard purchases. The response to the card fee was greater in low-income neighborhoods and among
riders who used cash or debit cards rather than credit cards. As a result, riders carried much larger unused
balances on their cards, and over $20 million a year more money escheated to the MTA when these cards
expired. These results may have implications for fare designs of public services.

“The Causal Effect of Institutional Discrimination on Health among Rural-to-Urban Migrants in China”
(revise and resubmit)
Abstract: Research on segregated and discriminated migrants has been done mostly in western context where
social segregation towards minority migrant population has already established. It is difficult to isolate the
influence of institutional discrimination and social stigma against migrant population. The unique household
registration (Hukou) system in China offer an opportunity to examine the effects of initial social segregation on
mental and physical health of migrants. Using change in hukou system in 1964, the regression-discontinuity
(RD) design estimates in this paper suggest that urban hukou citizens have much better chances of being in
good health. The deleterious effect of rural hukou on health possibly work through mechanisms of income
disparity, variations in educational attainment, and availability of health insurance.

Criminal Life Paths” Columbia Economics Wueller Pre-Dissertation Award (runner-up), Reubens Fellowship Award
Abstract: I study how exposure to illegal labor markets in childhood affects criminality in adulthood. To do so, I
exploit the timing of a large anti-drug policy in Colombia that shifted cocaine production to Peruvian districts wellsuited to growing coca. In these districts, children participate in tasks such as harvesting coca leaves and transporting
processed cocaine. Using variation across districts, years, and cohorts, I show that at times of high coca prices,
children in locations suitable for coca production are more likely to work, and have lower test scores and higher
dropout rates. As adults, these individuals are 30% more likely to be incarcerated for violent and drug-related crimes,
and are less likely to trust government institutions. This is true even for individuals who move to non-coca suitable
districts, implying that they developed criminal skills during childhood. Informed by a model of parental incentives, I
show that a conditional-cash-transfer program that encourages schooling and was rolled out gradually, mitigated the
effects by reducing drug production, child labor, and crime. Finally, I show how the program can be targeted taking
into account the geographic distribution of coca suitability and spatial spillovers in cocaine production within suitable
areas. Overall, this paper provides evidence on the early underpinnings of criminal careers by showing how crimespecific human capital can develop at the expense of other forms of human capital in “bad locations.”

Firm Culture and Innovation: The Extrinsic Motivation of Freedom at Work.
Why do workers perform better with more freedom at work? This paper provides an extrinsic motivation
of this phenomenon and introduces a novel view of firm culture as the information flow to the managers.
In a principal-agent setting in which innovations are not contractible ex-ante, the agent faces a ratchet
effect of innovating when monitored: if he uncovers a more efficient technology, the principal will raise his
performance requirement in the future; anticipating this, the agent never tries to innovate. By adopting
a “freedom-at-work” culture, the principal allows the agent to privately learn the outcome of his experimentation. The resulting information asymmetry compels the principal to share the innovation surplus
with the agent in the form of an information rent, thus giving the agent incentives to innovate. Perhaps counter-intuitively, the principal can benefit from generating asymmetric information against herself.
Managing Training and Production Activities in Organizations.
Sending workers for training improves their future productivity but comes at a cost of forgoing current
production. This paper studies dynamic contracting under this trade-off in the presence of moral hazard
on the worker’s production effort and adverse selection on his learning ability. I illustrate the effects of
the principal’s ability to observe the worker’s initial activity choice – training or production – on the
type of constraints in the contracting problem, the resulting form of the optimal contracts, and the type
of distortions in the second best.

Optimal Contracting with Subjective Evaluation: The Effects of Timing, Malfeasance and
Guile, NBER Working Paper 22156 (with W. Bentley MacLeod).
We introduce a general Principal-Agent model with subjective evaluation and malfeasance characterized
by two-sided asymmetric information on performance that allows for an arbitrary information structure.
Two generic contract forms are studied. An authority contract has the Principal reveal his information
before the Agent responds with her information. Under such a contract, the Agent’s compensation varies
only with the Principal’s information, while her information is used to punish untruthful behavior by
the Principal. Conversely, a sales contract has the Agent reveal her information first. In this case, the
Agent’s performance incentives are affected by the information revealed by both parties. Because the
Agent’s information affects her compensation, the information revelation constraints are more complex
under a sales contract, and provide a way to integrate Williamson’s (1975) notion of guile into agency
theory. We find that designing sales contracts for expert agents, such as physicians and financial advisors,
are significantly more complex than designing optimal authority contracts.
Work in Progress
Persuasion under Costly Lying.
I study the design of information acquisition structure when a Receiver relies on a Sender to report the
new information. Sender can misrepresent the new information at a lying cost. Under minimal assumptions on the lying cost, lying never occurs in the Sender-optimal equilibrium; instead, Sender designs
a vague information acquisition structure to gain credibility that he will not misrepresent any new information. This hampers the effectiveness of Sender’s persuasion. When Sender has state-independent
preference and constant lying cost, the optimal information structure can be derived using geometry
arguments. A comparison is drawn with the optimal information acquisition structure when Receiver
observes the new information directly.
Feedback and Belief Manipulation via Discretionary Rewards.
I study the role of information provision in discretionary rewards. In a principal-agent setting with
unknown state (eg. match quality) and subjectively evaluated outcomes (outcomes are privately observed
by the principal), discretionary bonus payments act as credible feedback to the agent. The incentive to
manipulate the agent’s belief about the state affects the relational contract and payment decision. Under
the principal-optimal equilibrium, the principal promises an excessively high bonus and pays it if and
only if she observes a good outcome (i.e. no lying about evaluation). I discuss the analogy with signaling
games and show that the principal-optimal equilibrium is the only equilibrium that survives the Cho and
Kreps (1987) Intuitive Criterion equilibrium refinement.

JOB MARKET PAPER
“COMPOSITE LIKELIHOOD ESTIMATION OF AR-PROBIT MODEL: APPLICATION TO CREDIT RATINGS”
Abstract: In this paper, persistent discrete data are modeled by Autoregressive Probit
model and estimated by Composite Likelihood (CL) estimation. Autocorrelation in the
latent variable results in an intractable likelihood function containing high dimensional
integrals. CL approach offers a fast and reliable estimation compared to computationally
demanding simulation methods. I provide consistency and asymptotic normality results
of the CL estimator and use it to study the credit ratings. The ratings are modeled as
imperfect measures of the latent and autocorrelated creditworthiness of firms explained
by the balance sheet ratios and business cycle variables. The empirical results show
evidence for rating assignment according to Through-the-cycle methodology, that is, the
ratings do not respond to the short-term fluctuations in the financial situation of the firms.
Moreover, I show that the ratings become more volatile over time, in particular after the
crisis, as a reaction to the regulations and critics on credit rating agencies.

Job Market Paper: “How to Measure Disagreement?”
This paper defines a quantitative measure of disagreement. I introduce six axioms that a
measure of disagreement should satisfy and then characterize all the functions that
represent it. I then consider two applications. First, I find necessary and sufficient
conditions for more public information to decrease disagreement between rational agents.
Second, I show that in an economy with heterogeneous beliefs, trade of contingent assets
is increasing in my measures of disagreement, and the asset prices are the beliefs that
minimize aggregate disagreement.
