Article
This study provides a new theoretical result that a decline in the long‐term interest rate can trigger a stronger investment response by market leaders relative to market followers, thereby leading to more concentrated markets, higher profits, and lower aggregate productivity growth. This strategic effect of lower interest rates on market concentra...
Article
The well-documented rise in political polarization among the U.S. electorate over the past 20 years has been accompanied by a substantial increase in the effect of partisan bias on survey-based measures of economic expectations. Individuals have a more optimistic view on future economic conditions when they are more closely affiliated with the part...
Article
Credit supply expansion boosts housing speculation and amplifies the housing cycle. The surge in private-label mortgage securitization in 2003 fueled a large expansion in mortgage credit supply by lenders financed with noncore deposits. Areas more exposed to these lenders experienced a large relative rise in transaction volume driven by a small gro...
Article
We propose a theory of indebted demand, capturing the idea that large debt burdens lower aggregate demand, and thus the natural rate of interest. At the core of the theory is the simple yet underappreciated observation that borrowers and savers differ in their marginal propensities to save out of permanent income. Embedding this insight in a two-ag...

We study bank credit booms, exploiting the Spanish matched credit register over 2001-2009. We extend Khwaja and Mian (2008)’s loan-level estimator by incorporating firm-level general equilibrium adjustments. Higher ex-ante bank real-estate exposure increases credit supply to non-real-estate firms, but effects are neutralized by firm-level adjustmen...
Article
Credit supply expansion can affect an economy by increasing productive capacity or by boosting household demand. In this study, we develop a test to determine if the household demand channel is present, and we implement the test using both a natural experiment in the U.S. in the 1980s and an international panel of 56 countries over the last several...
Article
What is the role of the financial sector in explaining business cycles? This question is as old as the field of macroeconomics, and an extensive body of research conducted since the Global Financial Crisis of 2008 has offered new answers. The specific idea put forward in this article is that expansions in credit supply, operating primarily through...
Article
We show that firm demand-side factors are strong drivers of procyclical refinancing behavior over the credit cycle using novel data from the Shared National Credit program. Firms are more likely to refinance early when credit conditions are good to keep the effective maturity of their loans long and hedge against having to refinance in tight credit...
Article
An increase in the household debt to GDP ratio predicts lower GDP growth and higher unemployment in the medium run for an unbalanced panel of 30 countries from 1960 to 2012. Low mortgage spreads are associated with an increase in the household debt to GDP ratio and a decline in subsequent GDP growth, highlighting the importance of credit supply sho...

Article
Treating fraudulently overstated income on mortgage applications as true income can lead to incorrect conclusions on the nature of the mortgage credit supply expansion toward marginal borrowers from 2002 to 2005. A positive gap between zip-code-level income growth calculated from mortgage applications and income growth from the IRS likely reflects...
Article
During the first decade of the 21st century, the United States witnessed a dramatic rise in household debt followed by a severe default crisis. In this study, we review the existing literature and provide new evidence supporting the credit supply view of the episode, which holds that an increase in credit supply unrelated to fundamental improvement...
Article
We show that deterioration in household balance sheets, or the housing net worth channel, played a significant role in the sharp decline in U.S. employment between 2007 and 2009. Counties with a larger decline in housing net worth experience a larger decline in non-tradable employment. This result is not driven by industry-specific supply-side shoc...
Article
How do large scale, involuntary migrations and population exchanges affect sending and receiving communities? We examine the case of the partition of India in which approximately 17 million people moved within four years, resulting in one of the largest and most rapid population exchanges in human history. We find large effects due to the migration...
Article
We examine the effect of rising U.S. house prices on borrowing and spending from 2002 to 2006. There is strong heterogeneity in the marginal propensity to borrow and spend. Households in low income zip codes aggressively liquefy home equity when house prices rise, and they increase spending substantially. In contrast, for the same rise in house pri...

Article
We investigate the consumption consequences of the 2006–9 housing collapse using the highly unequal geographic distribution of wealth losses across the United States. We estimate a large elasticity of consumption with respect to housing net worth of 0.6 to 0.8, which soundly rejects the hypothesis of full consumption risk-sharing. The average margi...
Article
A drop in aggregate demand driven by shocks to household balance sheets is responsible for a large fraction of the decline in U.S. employment from 2007 to 2009. The aggregate demand hypothesis for employment losses makes the joint prediction that job losses in the non-tradable sector will be higher in high leverage U.S. counties that were most seve...
Article
States without a judicial requirement for foreclosures are twice as likely to foreclose on delinquent homeowners. Comparing zip codes close to state borders with differing foreclosure laws, we show that foreclosure propensity and housing inventory jump discretely as one enters non-judicial states. There is no jump in other homeowner attributes such...

Debtors bear the brunt of a decline in asset prices associated with financial crises and policies aimed at partial debt relief may be warranted to boost growth in the midst of crises. Drawing on the US experience during the Great Recession of 2008-09 and historical evidence in a large panel of countries, we explore why the political system may fail...

This special issue of the B. E. Journal of Macroeconomics collects papers presented at a Conference on Empirical Macroeconomics Using Geographical Data, held at the Federal Reserve Bank of San Francisco on March 18, 2011.
Article
Full-text available
Foreclosures during the 2007 to 2009 recession had a large negative effect on house prices, residential investment, and durable consumption. Our empirical methodology uses state laws requiring a judicial foreclosure as an instrument for actual foreclosures, as well as focusing on zip codes very close to state borders with differing foreclosure laws...
Article
U.S. households accumulated debt at an unprecedented pace between 2001 and 2007. In the aftermath of the housing downturn, deleveraging by highly indebted households is the most important factor responsible for the current economic slump. The deleveraging process has led to sharp drops in both aggregate demand and employment. We argue that meaningf...
Article
We describe recent advances in the study of rent seeking and corruption in financial markets. We outline three areas of inquiry: (a) conceptualizing rent seeking, (b) identifying rent-provision channels and their general equilibrium impact, and (c) designing feasible remedial mechanisms. We provide suggestions for making further progress in these a...

To what extent can non-expert market participants collectively infer the underlying quality of an asset? We answer this question by examining a novel peer-to-peer lending market that allows us to estimate both the magnitude of inference and the degree to which it arises from different sources of information. Our methodology takes advantage of the f...
Article
We use the Shared National Credit data on syndicate loans to investigate U.S. firms’ refinancing behavior over the last two decades. As credit conditions tighten, refinancing likelihood goes down and draw down on loan commitments increases sharply. Surprisingly, refinancing propensity is most sensitive to credit market conditions for credit worthy...
Article
This paper uses the staggering timing of branching and interstate banking deregulation as a natural experiment to explore the effect of agency cost on the use of bank loan commitments. A simple inventory-based model shows that lower agency cost allows a bank to issue more loan commitments because lower agency cost alleviates the difficulty of liqui...
Article
We construct the topology of business networks across the population of firms in an emerging economy, Pakistan, and estimate the value that membership in large yet diffuse networks brings in terms of access to bank credit and improving financial viability. We link two firms if they have a common director. The resulting topology includes a "giant ne...
Article
We exploit an unexpected inflow of liquidity in an emerging market to study how capital is intermediated to firms. We find that backward-looking credit limit constraints imposed by banks make it difficult for firms to borrow, despite readily available bank liquidity, healthy aggregate demand, and a sharply falling cost of capital. The resulting agg...
Article
We evaluate the impact of the 2009 Cash for Clunkers program on short- and medium-run auto purchases. Our empirical strategy exploits variation across U.S. cities in ex ante exposure to the program as measured by the number of "clunkers" in the city as of summer 2008. We find that the program induced the purchase of an additional 370,000 cars in Ju...
Article
We show that household leverage as of 2006 is a powerful statistical predictor of the severity of the 2007 to 2009 recession across U.S. counties. Counties in the U.S. that experienced a large increase in household leverage from 2002 to 2006 showed a sharp relative decline in durable consumption starting in the third quarter of 2006 – a full year b...
Article
We highlight how a micro-level analysis of the Great Recession provides us with important clues to understand the origins of the crisis, the link between credit and asset prices, the feedback effect from asset prices to the real economy, and the role of household leverage in explaining the downturn. We hope that our discussion also serves as an exa...
Article
Borrowing against the increase in home equity by existing homeowners was responsible for a significant fraction of the rise in US household leverage from 2002 to 2006 and the increase in defaults from 2006 to 2008. Instrumental variables estimation shows that homeowners extracted 25 cents for every dollar increase in home equity. Home equity-based...
Article
We show that institutions that promote financial development ease borrowing constraints by lowering the collateral spread and shifting the composition of acceptable collateral towards firm-specific assets. Collateral spread is defined as the difference in collateralization rates between high- and low-risk borrowers. The average collateral spread is...

This paper provides a survey on studies that analyze the macroeconomic effects of intellectual property rights (IPR). The first part of this paper introduces different patent policy instruments and reviews their effects on R&D and economic growth. This part also discusses the distortionary effects and distributional consequences of IPR protection a...
Article
We conduct a within-county analysis using detailed ZIP code—level data to document new findings regarding the origins of the biggest financial crisis since the Great Depression. The sharp increase in mortgage defaults in 2007 is significantly amplified in subprime ZIP codes, or ZIP codes with a disproportionately large share of subprime borrowers a...
Article
Full-text available
We present evidence that a primary culprit for the severe U.S. recession of 2007 to 2009 is the dramatic expansion in household leverage from 2002 to 2006. The aggregate evidence shows that house prices, mortgage default rates, fixed residential investment, and durable consumption were the first serious signs of weakness in the economy, and all fou...

Large scale migrations, especially involuntary ones, can have a substantial impact on the demographics of both sending and receiving communities. We estimate the impact of the 1947 Indian subcontinent partition, one of the largest and most rapid population exchanges in human history. Comparing neighboring districts better isolates the effect of the...

The partition of India in 1947 along ostensibly religious lines into India, Pakistan, and what eventually became Bangladesh resulted in one of the largest and most rapid migrations in human history. We compile district level census data from archives to quantify the scale of migratory flows across the sub-continent. We estimate total migratory infl...

We examine the impact of liquidity shocks by exploiting cross-bank liquidity variation induced by unanticipated nuclear tests in Pakistan. We show that for the same firm borrowing from two different banks, its loan from the bank experiencing a 1 percent larger decline in liquidity drops by an additional 0.6 percent. While banks pass their liquidity...

We demonstrate that a rapid expansion in the supply of mortgages driven by disintermediation explains a large fraction of recent U.S. house price appreciation and subsequent mortgage defaults. We identify the effect of shifts in the supply of mortgage credit by exploiting within-county variation across zip codes that differed in latent demand for m...
Article
We construct a simple career concerns model where high-powered incentives can distort the composition of effort by inducing excessive signaling. We show that in the presence of this type of career concerns, markets typically fail to limit competitive pressures and cannot commit to the desirable low-powered incentives. Firms may be able to weaken in...

Article
The inability of developing countries to absorb and retain capital has long puzzled ob-servers. The unanticipated events of 9/11 simultaneously led to a surge in capital ow into Pakistan, and an increase in aggregate demand. Yet despite rising deposit to loan ratios and precipitous fall in cost of capital, banks showed remarkable hesitancy to expan...

This paper uses a unique dataset from Denmark to investigate the impact of family characteristics in corporate decision making, and the consequences of these decisions on firm performance. We focus on the decision to appoint either a family or an external chief executive officer (CEO). The paper uses variation in CEO succession decisions that resul...
Article
How far does mobility of multinational banks solve problems of financial development? Using a panel of 80,000 loans over 7 years, I show that greater cultural and geographical distance between a foreign bank's headquarters and local branches leads it to further avoid lending to "informationally difficult" yet fundamentally sound firms requiring rel...
Article
Collateral may be used as commitment against ex-ante agency risk, or for hedging against ex-post realized risk. Using a panel data of 9,000 small and medium firms in 15 countries with direct measures of ex-ante agency risk and ex-post realized default, we find that the commitment motive alone explains collateralization. Going from the lowest to hig...

How costly is the poor governance of market intermediaries? Using unique trade level data from the stock market in Pakistan, we find that when brokers trade on their own behalf, they earn annual rates of return that are 50-90 percentage points higher than those earned by outside investors. Neither market timing nor liquidity provision by brokers ca...
Article
Corruption by the politically connected is often blamed for economic ills, particularly in less developed economies. Using a loan-level data set of more than 90,000 firms that represents the universe of corporate lending in Pakistan between 1996 and 2002, we investigate rents to politically connected firms in banking. Classifying a firm as "politic...
Article
How does organizational design shape the behavior of banks? Using a panel data of over 1,600 banks in 100 emerging economies, we identify the strengths and weaknesses of the three dominant organizational designs in emerging markets. Private domestic banks have an advantage in lending to "soft information" firms which allows them to lend more, and a...
Article
Using a comprehensive database of European firms, we study how the business environment in a country drives the creation of new firms. Our focus is on regulations governing firm creation ("entry regulations") and on financial development. We find entry regulations hamper the creation of new firms, especially in industries that naturally should have...

Corrupt politicians are often blamed for economic ills, particularly in less developed economies. Using a loan-level data set containing all corporate loans in Pakistan between 1996 and 2002, we investigate political corruption in banking. Classifying a firm as "political" if its director participates in an election, we examine the extent, nature,...

Article
Most government expenditure is on goods that yield primarily private benefits, such as education, pensions, and healthcare. We argue that markets are most advantageous in areas where high-powered incentives are desirable, but in areas where high-powered incentives stimulate unproductive signalling effort, firms, or even government, may have a compa...

This paper uses a unique data set that contains detailed information on every corporate loan outstanding in the banking sector of Pakistan during 2001/2002 (52,000 loans). Using a simple empirical methodology that allows us to separately measure ex-ante monitoring, ex- post monitoring, "softness", renegotiation, recovery and litigation of loans, th...

The U.S. economic recovery has been weak, especially in employment growth. A microeconomic analysis of U.S. counties shows that this weakness is closely related to elevated levels of household debt accumulated during the housing boom. Counties where household debt grew moderately from 2002 to 2006 have seen a moderation of employment losses and a r...

The partition of the Indian sub-continent along religious grounds in 1947 into India, Pakistan and what eventually became Bangladesh, resulted in one of the largest and most rapid migrations in human history. This paper makes use of Indian and Pakistani census data, compiled at the district level by the authors, to quantify the size and nature of t...

In this paper, we investigate the link between financial development and exports. Using bilateral trade data, we find that having a better financial system increases exports. To explain this result, we propose that exporting firms face significant up-front fixed costs in product design, marketing, distribution etc. In an economy where outside finan...
Article
The events following 9/11 led to a sudden windfall for Pakistan as capital inflow surged, aggregate demand shot up, and cost of capital declined sharply. We couple this natural experiment with loan level data on 23,000 private firms to identify borrowing constraints at firm level, and provide economy wide estimate for the cost of these constraints....
Article
We estimate the eect of credit approval at higher hierarchical levels on the usage of soft and hard information. Credit approved at higher levels (that are more distant from the source of information generation) relies more on hard information content and less on soft information content. Since the assignment of …rms to approval levels is determine...
Article
A negative aggregate demand shock driven by household deleveraging is responsible for a large fraction of the decline in U.S. employment from 2007 to 2009. The deleveraging – aggregate demand hypothesis predicts that employment losses in the non-tradable sector will be higher in high leverage U.S. counties that experienced the bulk of the deleverag...

We analyze a unique data set containing daily firm-level trades of every broker trading on the main stock exchange in Pakistan over a 32 month period. A detailed look at the trading patterns of brokers trading on their own behalf reveals some "strange" patterns suggestive of price manipulation attempts. Comparing profitability levels of these broke...

We provide evidence on the causal link between financing constraints and the risk of corporate cash flows and returns. For identification, we compare public U.S. firms in the same industry, location, and size quintile, but whose access to bank credit was differentially affected by WorldCom's demise in 2002. A credit shortage induces a permanent inc...

... However, if interest rates are lower than GDP growth rates (r -g < 0), public debt dynamics are inherently stable, as the public-debt-to-GDP ratio will show a downward trend as long as there is not too large a primary fiscal deficit. Mian et al. (2022) argue that whether a modest permanent increase in the fiscal deficit can be sustained also depends on how strongly r-g reacts to changes in public debt. (Reis, 2021) proposes an analysis according to which there is still a well-defined government budget constraint with r<g if the economy is dynamically inefficient. ...
... 5 In models in which financial markets are incomplete and risk is uninsurable, a permanent increase in government debt can increase the supply of financial assets in the economy and raise the long-run level of the short-term real interest rate (hereafter referred to as r*), crowding out private capital. 6 In addition, Krishnamurthy and Vissing-Jorgensen (2012) have documented that there are safety and liquidity benefits associated with government securities, and in models such as Mian et al. (2022) a permanent increase in government debt can increase r* by reducing the convenience value associated with these benefits. Issuance of longer-term government securities can also raise the exposure that investors have to interest-rate risk on the value of longer-term securities in preferred habitat models of the yield curve (e.g., Vila, 2021, Greenwood andStein, 2014). ...
... compensatory rule for selecting the credit product and a lexicographic heuristic for selecting the INTRODUCTION Decision-making when choosing alternatives for financing a major purchase is a complex process which involves several cognitive aspects of consumer behavior. To choose optimally, consumers must evaluate various alternatives for financing and consider factors such as interest rates, loan terms, and credit limits (Ranyard et al., 2018;Liu et al., 2022;Kirchler & Hoelzl, 2018). ...
... At the same time, recent work in the United States shows that increasing indebtedness among average households and in government has taken place alongside the development of a "savings glut" among the rich. This increasing wealth at the top of the distribution (including financial assets that amount to direct claims on government and household debt) has not been accompanied by greater rates of investment that might spur economic growth (Mian et al., 2020). Later work also identifies the development of a savings glut among the rich and dissaving among the rest of the population in the EU and China over the last forty years (Bauluz et al., 2022). ...
... 34 Consistent with a multi-factor extension of our model, exposures to both country and global risk are associated with lower labor shares. 35 We follow Kroen, Liu, Mian, and Sufi (2021) and define superstar firms as the top 5% of firms within each Fama-French industry (in a given country-year). Table 4 formally investigates whether increases in international diversification, measured as the share of domestic firm equity held by foreign investors, leads to a reallocation of input and output shares to riskier firms by estimating regressions of firm shares of industry employment/sales on the interaction of the (log) foreign equity share with firm relative beta as implied by (14). ...
... If, for instance, a bank is bailed out, its creditors-institutional investors-and deposit holders with savings above deposit insurance limits are those who benefit. If central banks or other actors stabilize or boost asset values, those who hold these securities, i.e. the (white) middle classes [Bartscher et al. 2022] and rich households with diversified financial portfolios and large stock ownership [Mian, Straub, and Sufi 2020], are the primary winners. Interventions like QE and loan guarantee programmes also help leveraged debtors, both within professional finance and in the household sector. ...
... New evidence suggests that rising income inequality might be a more important factor in explaining the decline in r* than demographics. Based on micro data, Mian et al. (2021a) weigh the relative importance of demographic shifts versus rising income inequality on saving behavior in the US from 1950 to 2019. These findings challenge the view that the aging of the baby boomers explains the decline in r* and might taper off as baby-boomers retire. ...

The relationship between political partisanship and inflation expectations (and, more generally, evaluations of the economy) is explored in literature investigating polarization and partisan bias in economic perceptions (both retrospective and prospective) and the implications of such bias (Ladner & Wlezien, 2007;Gerber & Huber, 2010;McGrath, 2017;Gillitzer & Prasad 2018;Bachmann et al., 2021;Gillitzer et al., 2021;Mian et al., Khoshkhou 2023). In the case of this literature, partisan bias is present when perceptions/expectations are polarized in such a way that Democrats and Republicans demonstrate favoritism towards their respective party, i.e., individuals from the president's political party perceive the same economic information more favorably than individuals from the opposing political party. ...
