We present a menu-cost pricing model with a large but finite number n of firms. A firm’s nominal price increase lowers other firms’ relative prices, thereby inducing further nominal price increases. The distribution of these repricing avalanches converges as n→∞ to a mixture of...

Loan syndication increases bank interconnectedness through co-lending relationships. We study the financial stability implications of such dependency on syndicate partners in the presence of shocks to banks' capital. Model simulations in a network setting show that such shocks can produce rare...

This paper analytically demonstrates that the tails of income and wealth distributions converge to a Pareto distribution in a variation of the Solow or Ramsey growth model where households bear idiosyncratic investment shocks. The Pareto exponent is shown to be decreasing in the shock variance,...

This paper studies the effect of strategic complementarity among firms' lumpy investments on the fluctuations of aggregate investments. We investigate an extensive panel data set on Italian manufacturing firms. We first show that the fluctuations of fraction of firms that experience large...

This paper presents a model of endogenous fluctuations of investment and output at the business cycles frequencies. Aggregate investments fluctuate endogenously due to the strategic complementarity of micro-level lumpy investments. The investment fluctuations are transmitted to the output via...

This paper quantifies the effects of precautionary savings. It demonstrates that Zeldes' estimate (1989) of excess consumption growth for low asset holders is consistent with a dynamic general equilibrium model with uninsurable endowment shocks when borrowing is constrained at three months'...
