We quantify agency conflicts induced by the separation of ownership and control in large public firms by means of structural estimation. We use a simulated method of moments estimator (SMM) to back out the structural parameters of a q-theoretic dynamic agency model of firms from observed...

We compare the ability of three measurement error remedies to deliver unbiased estimates of coefficients in investment regressions. We examine high-order moment estimators, dynamic panel estimators, and simple instrumental variables estimators that use lagged mismeasured regressors as...

This chapter discusses how applied researchers in corporate finance can address endogeneity concerns. We begin by reviewing the sources of endogeneity - omitted variables, simultaneity, and measurement error - and their implications for inference. We then discuss in detail a number of...

We construct novel measures of financial constraints using textual analysis of firms' annual reports and investigate their impact on stock returns. Our three measures capture access to equity markets, debt markets, and external financial markets in general. In all cases, constrained firms earn...

Cities exist because of the productivity gains arising from clustering production and workers, a process called agglomeration. How important is agglomeration for aggregate growth? This paper constructs a dynamic stochastic general equilibrium model of cities and uses it to estimate the effect of...
