Limited Capital Market Participation and Human Capital Risk

The Review of Asset Pricing Studies 2013 3(1), 1-37 open access
By introducing a labor market into the neoclassical asset pricing model, limited capital market participation can be an equilibrium outcome. Labor contracts are derived endogenously as part of a dynamic equilibrium in a production economy. Firms write labor contracts that insure workers, allowing agents to achieve a Pareto optimal allocation even when the span of asset markets is restricted to just stocks and bonds. Capital markets facilitate this risk sharing because it is there that firms offload the labor market risk they assumed from workers. In effect, by investing in capital markets, investors provide insurance to wage earners who then optimally choose not to participate in capital markets. (JEL G11, G12)

Alternative Measures of Offshorability: A Survey Approach

Journal of Labor Economics 2013 31(S1), S97-S128 open access
This article reports on household survey measurements of the “offshorability” of jobs, defined as the ability to perform the work from abroad. We develop multiple measures of offshorability, using both self-reporting and professional coders. All measures find that roughly 25% of US jobs are offshorable. Our three preferred measures agree between 70% and 80% of the time. Professional coders appear to provide the most accurate assessments. Empirically, more educated workers appear to hold somewhat more offshorable jobs, and offshorability does not have systematic effects on either wages or the probability of layoff.

Zero-R2Hedge Funds and Market Neutrality

Journal of Financial and Quantitative Analysis 2013 48(2), 519-547
Factor models yield an R 2 insignificantly different from 0 for one-third of hedge funds in a broad sample. These funds illustrate the concept of market neutrality and feature lower volatilities, higher Sharpe ratios, and higher alphas than other funds, indicating that they provide a successful alternative investment. However, large portfolios of zero- R 2 funds contain fully half the volatility of portfolios of other funds, suggesting that they feature substantial systematic risk. Furthermore, these funds display an increased probability of failure even after controlling for idiosyncratic volatility. These results indicate the presence of an omitted factor that exposes investors to significant downside risk.

Analyzing the Extent and Influence of Occupational Licensing on the Labor Market

Journal of Labor Economics 2013 31(S1), S173-S202
This study examines occupational licensing in the United States using a specially designed national labor force survey. Estimates from the survey indicated that 35% of employees were either licensed or certified by the government and that 29% were licensed. Another 3% stated that all who worked in their job would eventually be required to be certified or licensed, bringing the total that are or eventually must be licensed or certified by government to 38%. We find that licensing is associated with about 18% higher wages but that the effect of governmental certification on pay is much smaller.

Optimal Corporate Governance in the Presence of an Activist Investor

Review of Financial Studies 2013 26(4), 985-1020
[We provide a model of governance in which a board arbitrates between an activist investor and a manager facing reputational concerns. The optimal level of internal board governance depends on both the severity of the agency conflict and the strength of external governance. Internal governance creates a certification effect, so greater intervention by the board can lead to worse managerial behavior. Internal and external governance are substitutes when external governance is weak (the board commits to an interventionist policy to induce participation from the activist) and complements when external governance is strong (the board relies to a greater extent on the activist's information).]

Flow and stock effects of large-scale treasury purchases: Evidence on the importance of local supply

Journal of Financial Economics 2013 108(2), 425-448
The Federal Reserve’s 2009 program to purchase $300 billion of US Treasury securities represented an unprecedented intervention in the Treasury market and provides a natural experiment with the potential to shed light on the price elasticities of Treasuries and theories of supply effects in the term structure. Using security-level data on Treasury prices and quantities during the course of this program, we document a ‘local supply’ effect in the yield curve—yields within a particular maturity sector responded more to changes in the amounts outstanding in that sector than to similar changes in other sectors. We find that this phenomenon was responsible for a persistent downward shift in yields averaging about 30 basis points over the course of the program (the “stock effect”). In addition, except at very long maturities, purchase operations caused an average decline in yields in the sector purchased of 3.5 basis points on the days when those operations occurred (the “flow effect”). The sensitivity of our results to security characteristics generally supports a view of segmentation or imperfect substitution within the Treasury market during this time.

Debt, equity, and capital investment

Journal of Accounting and Economics 2013 56(2-3), 291-310
Theory suggests that debt financing, relative to equity financing, makes managers reluctant to part with assets. Our evidence supports this theoretical prediction, revealing that the reluctance to part with a debt financed asset causes two decision errors—(1) participants forego investments that increase firm value and (2) participants accept investments that decrease firm value. When the source of finance is equity, participants are less likely to make either of these costly decision errors. Further, we find that higher unpaid principal accentuates participants' reluctance to part with debt financed assets. Finally, the decision errors stem, in part, from the perception that an asset having a large unpaid principal balance has provided lower past benefits than an otherwise identical asset.
