Research Statement
My
research program in macroeconomics and finance focuses on three areas:
interactions between asset markets and the real economy, the business
cycle, and corporate finance. My dissertation explores this agenda with
computational, econometric, and analytic tools.
The travails of the global economy in the last five years are deeply
intertwined with the gyrations of housing, stock, and bond markets.
This has hammered home the necessity of incorporating financial markets
with macroeconomics. This motivation was firmly in mind when writing my
job market paper, “The Effects of Housing Adjustment Costs on
Consumption Dynamics”. Homes are the largest asset on most households'
balance sheets. Unfortunately, most work in macroeconomics ignores
housing's unique features: differing expected returns, costly
adjustment, minimal correlation with stock market returns, and that it
is also a source of consumption services. Canonical frictionless models
predict that consumption and portfolio choices are constant fractions
of wealth. In the presence of a realistic treatment of housing, I find
consumption and portfolio choices depend not just on wealth but also on
the price and quantity of housing. These features allow the model to
match (in a S.S.E. and standard deviation sense) NIPA non-durable
consumption changes better than frictionless models. Further, the model
predicts the timing and magnitude of housing adjustments in response to
the Great Recession.
In future work, I plan to add new features to this model including:
human capital to the household portfolio, life-cycle housing adjustment
motives, and intensive adjustment to housing. Another planned extension
is to test whether the differential responses of house-poor and
house-rich households to wealth shocks predicted by the model are borne
out in panel data. A third extension will exploit regional home price
dynamics to assess the contribution of housing to economic dynamics.
Related work that is underway (coauthored with Jess Diamond of The Bank
of Japan) explores how segmentation of housing markets provides
additional power for estimating the stochastic discount factor and
forming a more plausible market portfolio for CAPM analyses.
The second chapter of my dissertation, “Employment and the Great
Moderation: International Evidence” (coauthored with Thomas Daula
of UCSD) considers international business cycle dynamics. We study the
reasons for the prolonged period of stability that marks the Great
Moderation and the apparent exit from that regime with the 2008
financial crisis. There are three explanations: i) good luck, ii) good
policy and iii) structural change. Though the Great Moderation was a
global phenomenon, the literature has focused on explanations based on
American experiences of monetary policy and structural change. There
remains significant disagreement over the results of these
investigations. Galí and van Rens (2010) accounts for the decline in
output volatility and a number of recently documented employment
regularities with a single cause, the decline in American labor market
frictions. We consider employment and output across 14 OECD countries
and find that under a variety of econometric techniques the US
experience is atypical. Under Galí and van Rens, this would be caused
by differences in labor frictions. We estimate labor frictions with
data from the OECD and the LSE Centre for Economic Performance. We find
international differences in labor frictions do not explain differences
in business cycle dynamics and therefore it is unlikely that structural
change in the labor market can account for the Great Moderation. This
narrows the field of possible alternatives to the null hypothesis of
good luck.
Since others have argued that better monetary policy is an important
cause of the Great Moderation, future work will extend the model to
have a monetary policy channel. This project alerted us to the
widespread use of univariate filtering in studying macroeconomic
dynamics. Since univariate filtering may induce spurious relationships
and needlessly reduce statistical power, future work will revisit those
analyses with multivariate filtering.
The third chapter of my dissertation, “How Do Firms Switch Among Tools
Used to Monitor the Agency Problem?” (coauthored with Cindy Vojtech of
the Federal Reserve Board) explores the relationships between the
mechanisms that mitigate agency problems. Since firms face differing
monitoring costs and levels of agency problems, the portfolio of
monitoring tools selected is endogenous to firm characteristics. The
minimum requirements on board composition established by the
Sarbanes–Oxley Act and contemporaneous changes in NASDAQ and NYSE rules
provide exogenous variation in monitoring. We study how treated firms
adjust their choice and magnitude of monitoring methods in response to
this natural experiment using a difference-in-differences estimation
strategy. Depending on the rule change, we find that treated firms
decreased dividends and on average lowered CEO ownership by 1.9% and
lowered leverage by 1.6%. This provides evidence that independent board
members are substitutes for other techniques to address the
principal-agent dilemma such as dividends, CEO ownership, and debt.
Currently, we are extending the paper by examining measures of good
governance before the law change. Our goal is to establish if there was
variation in the degree of substitution and complementarity with
pre-law change governance. We hope to continue this line of research by
examining other natural experiments in governance and managerial
independence.
