Nirei and Scheinkman (2021) proposed an equilibrium model of price adjustments with menu-costs with a finite number of firms and derived a "reproduction number" for repricing and a limit functional form for the distribution of the number of simultaneously price-adjusting firms. We show that the...

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 Generalized...

The Amazon rainforests have been undergoing unprecedented levels of human-induced disturbances. In addition to local impacts, such changes are likely to cascade following the eastern-western atmospheric flow generated by trade winds. We propose a model of spatial and temporal interactions...

The death of an artist constitutes a negative supply shock to his future production; in finance terms, this supply shock reduces the artist's float. Intuition may thus suggest that this supply shock reduces the future auction volume of the artist. However, if collectors have fluctuating...

We study asset and debt characteristics of US bank holding companies. We show that financial institutions, especially large institutions, are not just about holding discrete assets. Services and going-concern values are important, and capital market debt against going-concern values accounts for...

Asset prices contain information about the probability distribution of future states and the stochastic discounting of these states. Without additional assumptions, probabilities and stochastic discounting cannot be separately identified. Ross (2013) introduced a set of assumptions that restrict...

We present a novel approach to depicting asset pricing dynamics by characterizing shock exposures and prices for alternative investment horizons. We quantify the shock exposures in terms of elasticities that measure the impact of a current shock on future cash-flow growth. The elasticities are...

This paper investigates the determinants of informal economic activity. We present two equilibrium models of informality and test their implications using a survey of 48,000+ small firms in Brazil. We define informality as tax avoidance; firms in the informal sector avoid tax payments but suffer...

We propose a continuous-time model of trading among risk-neutral agents with heterogeneous beliefs. Agents face quadratic costs-of-carry on their positions and as a consequence, their marginal valuation of the asset decreases when the magnitude of their position increases, as it would be the...

The short ratio - shares shorted to shares outstanding - is an oft-used measure of arbitrageurs' opinion about a stock's over-valuation. We show that days-to-cover (DTC), which divides a stock's short ratio by its average daily share turnover, is a more theoretically well-motivated measure...
