The previous literature on optimal monetary policy has focused mainly on dynamic stochastic general equilibrium models with a constant aggregate capital stock (cf. Woodford 1999; Erceg et al. 2000). In this paper, we analyze the monetary policy implications of endogenous capital accumulation. We...

Robust control allows policymakers to formulate policies that guard against model misspecification. The principal tools used to solve robust control problems are state-space methods (see Hansen and Sargent, 2005, and Giordani and Soderlind, 2004). In this paper we show that the structural-form...

Infinitely repeated games have been used to argue that reputation can substitute for commitment in monetary policymaking. A drawback of this approach is that it implies multiple equilibria. I argue that nominal asset prices can be used as an equilibrium selection mechanism. First, I introduce...

We focus on a quantitative assessment of rigid labor markets in an environment of stable monetary policy. We ask how wages and labor market shocks feed into the inflation process and derive monetary policy implications. We structurally model matching frictions and rigid wages in line with an...

This paper compares wealth portfolios across countries. The household sector in the US and Canada owns much more financial wealth, and much less housing wealth, than the household sector in most of Europe. We address this fact using a calibrated two sector growth model with endogenous financial...

This paper estimates a structural model of firm growth and partially sunk investment. In the model, the firm's optimal adjustment keeps the gap between the actual capital stock and its frictionless counterpart between two boundaries. We show that any two quantiles of output growth conditional on...

This paper studies the choice between investment in new and used capital. We argue that used capital inherently relaxes credit constraints and thus firms which are more credit constrained invest more in used capital. Used capital is cheap relative to new capital in terms of its purchase price...

Tobin's Q exceeds one, even without any adjustment costs, for a firm that earns rents as a result of monopoly power or of decreasing returns to scale in production. Even when there are no adjustment costs and marginal Q is always equal to one, Tobin's Q is informative about the firm's growth...

This paper studies the provision of incentives to reallocate capital when managers are reluctant to relinquish control and have private information about the productivity of assets under their control. We show that when managers get private benefits from running projects substantial bonuses are...
