Title: Decomposing Firm Value
**Preliminary work with Vito Gala (Wharton), John Pokorny (U of M) and Juliana Salomao (U of M)
Title: Why can't CEOs foresee a financial crisis?
Abstract:This paper explains why CEOs are unable to curtail risky investments before a crisis. CEOs rely on the advice of their employees to understand the riskiness of their investments. Before a crisis, prots from an investment strategy is usually high, and so it is perceived to be good. If employees receive information that the strategy is bad and should be discontinued, they may not disclose their information to avoid being perceived as pessimistic and lose their job. Multiple employees can convince the CEO to discontinue if they disclose together but not if they disclose alone. This creates strategic complementarities in disclosure strategy and results in coordination problem where in the inefficient equilibrium no employee will disclose and the CEO remaining unaware of the risks goes ahead with bad investments. The paper thus provides an explanation for boom bust cycles and also for why CEO's beliefs were optimistic before the crisis.
Title: Capital Heterogeneity, Time-to-build, and Return Predictability
Abstract:This paper documents that U.S. equipment investment rate predicts stock market returns better than structures investment rate. This empirical finding is further borne out by industry-level and international data. A general equilibrium model with external habit preference and heterogeneous time-to-build for equipment and structures can explain the empirical findings while matching the salient features of business cycles and asset prices. Equipment investment requires less time to transform into productive capital. It reacts to productivity shocks more timely than structures investment and reflects more information contained in stock prices.
"Nominal frictions, leverage, and investment"
I find that nominal debt contracts and nominal price stickiness create a channel for inflation to affect real investment and leverage decisions. When debt in is nominal terms, Inflation lowers the real value of current debt, increases the marginal cost of issuing debt, and reduces the optimal amount of leverage. This reduces the degree of debt overhang, increasing investment. Firms with flexible prices invest more. I confirm these predictions empirically using a measure of price stickiness. Firms increase investment and reduce debt when inflation is high. Firms with sticky prices have lower investment and higher debt following inflation shocks.

TITLE: "Aggregation in Economies with Homogeneous Decision Rules"
"Adverse selection and asset sales"
I consider a dynamic adverse selection problem in OTC markets. One seller with private information about asset quality searches buyers sequentially in the market. Two types of buyers exist in the market (informed and uninformed). Buyers make private offers to sellers if they meet, and sellers decide whether to accept the offer. I find that there exists a unique stationary market belief, and belief will converge to this stationary belief if trading hasn't occurred. When the market belief is unfavorable, the high type seller trades more slowly, and the average trading time for high type seller is longer than low type; when the market belief is favorable, high type seller trades more quickly, and the average trading time for high type seller is shorter than low type seller.

Author: Martin Szydlowski, Briana Chang
Presenter: Martin Szydlowski
We study decentralized markets in which advisers have conflicts of interest and compete for customers via information provision. We show that competition partially disciplines conflicted advisers. The equilibrium features information dispersion and sorting of heterogeneous customers and advisers: advisers with expertise in more information sensitive assets attract less informed customers, provide worse information, and earn higher profits. We further apply our framework to the market for financial advice and establish new insights: it is the underlying distribution of financial literacy that determines the consumers’ welfare. When advisers are scarce, the fee structure of advisers is irrelevant for the welfare of consumers.

Title: The Effect of Cash Injections: Evidence from the 1980s Farm Debt Crisis
Authors: Nittai Bergman, Rajkamal Iyer, Richard Thakor
Abstract: What is the effect of cash injections during financial crises? Exploiting county-level variation arising from random weather shocks during the 1980s Farm Debt Crisis, we analyze and measure the effect of local cash flow shocks on the real and financial sector. We show that such cash flow shocks have significant impact on a host of economic outcomes, including land values, loan delinquency rates, and the probability of bank failure. Further, we measure how cash injections affect local labor markets, analyzing the impact on employment and wages both within and outside of the sector receiving a positive cash flow shock. Estimates of the effect of local cash flow shocks on county income levels during the financial crisis yield a multiplier of 1.63.
Title: Moral Hazard and Investment-cash-flow sensitivity, with Rui Li (University of Massachusetts) and Kai Li (HKUST)
Abstract: We present a dynamic model of investment with moral hazard. We show that the optimal contract with moral hazard gives rise to endogenous financing constraints and results in investment-to-cash flow sensitivity. In addition, the magnitude of invest-to-cash flow sensitivity does not increase with the tightness of financing constraints and therefore cannot be used as a quantitative measure of such. Our calibrated model replicates the failure of Q-theory, provides an explanation for the existence of investment-cash flow sensitivity, and accounts for the robust
positive relationship between investment-to-cash flow sensitivity and firm size and age in the data.
Abstract:This paper studies the strategic role of debt structure in improving the bargaining position of a firm's management relative to its non-financial stakeholders. Debt structure is essential for strategic bargaining since it affects the ease of debt contract renegotiation and thus the credibility of bankruptcy threat. We first document that the degree of wage concessions is indeed strongly related to a firm's debt structure ex post in the airline industry and the effect is reduced when bankruptcy threat is less credible for employees. Debt structure is further shown to be adjusted ex ante as a response to an increase in non-financial stakeholders' negotiation power. Utilizing NLRB labor union election as a laboratory setting and employing a regression discontinuity design, we find that passing a union election leads to an increase in the ratio of public debt to total asset and a decrease in the ratio of bank debt to total asset in the following three years after elections, while there is no significant change in the level of debt. Syndication size of newly issued bank loans increases while creditor ownership concentration decreases once vote share for unions passes the winning threshold. Various tests confirm that the debt structure adjustment after new unionization is more likely driven by strategic concerns of management rather than more constrained access to bank loans.
TITLE: Asset Pricing and Risk Sharing with Limited Enforcement and heterogeneous Preferences
Title: Why do banks ignore the warnings?
Abstract:Although the recent financial crisis came as a surprise to many, there were some employees who had warned against these risks. These warnings were ignored by the CEOs of the banks and the employees were fired. In my paper, I provide a theory of when will a CEO fire the employees and go ahead with risky strategies. Under the condition that one may get fired, the decision of the employees to disclose his concerns leads to a coordination problem among the employees. In a global games setting I show that, banks are more likely go ahead with the risky strategies when they seem to be more profitable.
Title: Uninsurable Tail Risks, Operating Leverage and the Value Premium
Can the usual tests of the Catering Theory of corporate investment distinguish between behavioral and rational perspectives? Using USA data from 1970 to 2015 we find test result which have been used in support of behavioral Catering Theory. We present a simple rational model of corporate investment and equity issuance. Data generated by the calibrated model produces the same patterns of coefficients as real data. According to behavioral, periods of high market sentiment and booms, are times of overvaluation. Using these periods we find that the patterns of coefficients are consistent with the rational model and not consistent with the behavioral predictions.

Cash holdings and technological development: Evidence from IT mediated improvement in inventory management
Since 1980s US manufacturing firms are holding more cash relative to their assets. In this paper, we investigate whether improvements in information technology (IT) and its use have contributed to this increase. We establish that IT contributed to the improvement through inventory channel. IT has enabled firms redeploy their current assets: substituting cash for inventory, engendering an era of sustained higher level of cash holdings. In addition, we also establish that some observed heterogeneity in cash holdings can be explained by the industries firms operate in, the type of inventories they hold, and the financial constraints they face.

(joint with Qi Liu, Libin Tao, and Weixing Wu)Numerous studies argue that the market risk premium is associated with economic conditions and show that proxies for business conditions indeed predict aggregate market returns. By directly estimating short- and long-run expected economic growth,we show that short-run expected economic growth is negatively related to future returns, whereas long-run expected economic growth is positively related to aggregate market returns. At an annual horizon, short- and long-run expected growth can jointly predict aggregate excess returns with an R2 of 17-19%. Our ndings indicate that the risk premium has both high- and low-frequency fluctuations and highlight the importance of distinguishing short- and long-run economic growth in macro asset pricing models.

A Mechanism Design Model of Firm Dynamics: The Case of Limited CommitmentWe present a general equilibrium-mechanism design model with two-sided limitedcommitment that accounts for the observed heterogeneity in firms' ;investment, payout and CEO-compensation policies. In the model, shareholders cannot commit to holding ;negative net present value projects, and managers cannot commit to ;compensation plans that yield life-time utility lower than their outside ;options. Firms operate identical constant return to scale technologieswith i.i.d.\ productivity growth. Consistent with the data, the model endogenouslygenerates a power law in firm size and a power law in CEO compensation. ;We also show that the model is able to quantitatively explain the observed negative ;relationship between firms' investment rates andsize, the positive relationship between firms' size and their dividend and CEO payout, as well as ;variation of firms' investment and payout policies across both size and age.
Crash Risk in Currency Returns
We quantify crash risk in currency returns. To accomplish this task, we develop and estimate an empirical model of exchange rate dynamics using daily data for four currencies relative to the US dollar: the Australian dollar, the British pound, the Swiss franc, and the Japanese yen. The model includes (i) normal shocks with stochastic variance, (ii) jumps up and down in the exchange rate, and (iii) jumps in the variance. We identify these components using data on exchange rates and at-the-money implied variances. We find that crash risk is time-varying. The probability of an upward (downward) jump in the exchange rate, associated with depreciation (appreciation) of the US dollar, is increasing in the domestic (foreign) interest rate. The probability of jumps in variance is increasing in the variance but is not related to interest rates. Many of the jumps in exchange rates are associated with macroeconomic and political news, but jumps in variance are not. On average, jumps account for 25% (and can be as high as 40%) of total currency risk, as measured by the entropy of exchange rate changes, over horizons of one to three months. Preliminary analysis suggests that these properties of currency returns correspond to observed option smiles and that jump risk is priced.
CEO Investment Cycles
This paper documents the existence of a CEO Investment Cycle, in which firms disinvest early in a CEO's tenure and increase investment subsequently, leading to cyclical firm growth in assets as well as in employment over CEO tenure. The CEO investment cycle occurs for both firings and non-performance related CEO turnovers, and for CEOs with different relationships with the firm prior to becoming CEO. The magnitude of the CEO cycle is substantial: The estimated difference in investment rate between the first three years of a CEO's tenure and subsequent years is approximately 6 to 8 percentage points, which is of the same order of magnitude as the differences caused by other factors known to affect investment, such as business cycles or financial constraints. We present a variety of tests suggesting that this investment cycle is best explained by a combination of agency-based theories: Early in his tenure the CEO disinvests poorly performing assets that his predecessor established and was unwilling to give up on. Subsequently, the CEO overinvests when he gains more control over his board. There is no evidence that the investment cycles occur because of shifting CEO skill or productivity shocks. Overall, the results imply that public corporations' investments deviate substantially from the first-best, and that governance-related factors internal to the firm are as important as economy-wide factors in explaining firms' investments.

CEO Compensation and Maturity of Debt Issues: Evidence From IRC 162(M)
This essay shows that CEO incentives provided by option compensation have significant impacts on maturity of newly issued debt. To identity such impacts, we exploit IRC 162(M) as an exogenous shock to new option grant decisions. IRC 162(M), effective since January 1st, 1994, limits corporate tax deductibility of CEO compensation and also has impacts on new option grant decisions in US firms. Our main findings are: First, after introduction of IRC 162(M), number, volatility sensitivity and price sensitivity of newly granted options in affected firm increase more than those in unaffected firms. Second, maturity of newly issued debt decreases (increases) when volatility (price) sensitivity of new option compensation increases. Overall, results in this essay show that CEO option compensation has large impacts on maturity of newly issued debt.
Short Arbitrage and Abnormal Return Asymmetry
This paper studies how constraints on short arbitrage are associated with abnormal return asymmetry of a broad set of anomalies. Using institutional holdings as a proxy for ease of short selling and idiosyncratic volatility for arbitrage risk, We find that the return asymmetry is stronger when short arbitrage is more constrained (low institutional holdings and high idiosyncratic volatility).
|10/30/13||Sangiago Bazdresch||Out of Sample Prediction tests for a Structural Model of Investment and Financing|
Liabilities ceded by life insurers to shadow reinsurers (i.e., less regulated off-balance-sheet entities) grew from $11 billion in 2002 to $363 billion in 2012. Companies that are involved in shadow insurance, which capture 50 percent of the market share, ceded 28 cents of every dollar insured to shadow reinsurers in 2012, up from 2 cents in 2002. Our adjustment for shadow insurance reduces risk-based capital by 49 percentage points (or 3 rating notches) and raises expected loss by at least $15.7 billion for the industry. We develop a structural model to estimate the impact of shadow insurance on the equilibrium supply in the retail market. In the absence of shadow insurance, marginal cost would rise by 1.8 percent, and annual insurance underwritten would fall by $1.4 billion at unit demand elasticity.

Equilibrium Corporate Capital Structure (work-in-progress with Hong Chen, SAIF)
The trade-off theory of corporate capital structure has been studied in partial equilibrium settings, and in dynamic models that require numerical solutions. Separately, as a result of the financial crisis of 2007-2009, there are studies of financial frictions at the bank. These models are used to study "unconventional Fed policy" along the lines of the policies actually adopted during the crisis. We bring a simple financing friction model closer to the trade-off theory, by permitting equity finance. Cases with and without corporate tax, and the financing friction (bank default) are compared. Results similar to Modigliani-Miller (1958 and 1963) emerge naturally as special cases. Allowing for an equity market tends to undermine the policy justifications of "unconventional Fed policy" because investment tends to avoid distorted markets when an undistorted alternative is available. In contrast to the usual trade-off theory models, the corporate tax rate may affect the volume of household savings and hence the scale of firm production, but not the equilibrium leverage ratio in some equilibria.
