Understanding Climate Damages: Consumption versus Investment
Existing climate-economy models use aggregate damage functions to model the effects of climate change. This approach assumes climate change has equal impacts on the productivity of firms that produce consumption and investment goods or services. We show the split between damage to consumption and investment productivity matters for the dynamic consequences of climate change. Drawing on the structural transformation literature, we develop a framework that incorporates heterogeneous climate damages. When investment is more vulnerable to climate, we find short-run consumption losses will be ...

Endogenous Option Pricing
We show that a structural model of firm decisions can produce very flexible implied volatility surfaces: upward and downward sloping, u-shaped. A calibrated version of the model is able to match many unconditional financial characteristics of the average option-able stock, and can help explain how, contrary to simple economic intuition, more valuable growth and contraction options are associated with a more negatively sloped implied volatility curve (i.e., a more negatively skewed implied distribution).

Gambling for Dollars: Strategic Hedge Fund Manager Investment
Hedge fund managers differ in ability and investors want to distinguish good ones from bad. Via the design of their investment strategies, better fund managers want to ease this inference problem while worse fund managers want to complicate it. We impose only the minimal restrictions on the nature the investment strategies that, on average, returns reflect the hedge fund manager?s ability and that returns be bounded from below, and solve for the set of equilibria that emerge. We then show that under a variety of equilibrium refinements, a unique equilibrium obtains. In this equilibrium, ...

New Data on Wealth Mobility and Their Impact on Models of Inequality
Using data on families? wealth over time, we calculate changes in relative wealth mobility; that is, how likely families are to move up or down the wealth distribution, relative to one another. We find families have become less likely to change their position in the wealth distribution over time, and those that do move are less likely to go very far. We also look at the savings behaviors that are associated with more mobile families and find that families that make large movements through the wealth distribution appear to be more likely to own some form of a risky asset.

The Profitability Channel of Monetary Policy Transmission
We provide firm-level evidence that Federal Open Market Committee announcements have real effects by changing expectations of firm profitability. We use an existing decomposition of a monetary policy shock into a central bank information component (CBI) and a conventional monetary component (MP). We find (1) firms with a higher value of capital asset pricing model (CAPM) beta have a higher investment rate sensitivity to the CBI component; no similar heterogeneity in investment response is observed for the MP component. We also find (2) the heterogeneity in investment sensitivity is due to ...

Has Business Fixed Investment Really Been Unusually Low?
Business fixed investment represents the spending by businesses to increase production capacity. It is traditionally decomposed into equipment (such as computers and machines), structures (such as plants, shopping malls, or warehouses), and intellectual property (such as software and R&D). After declining sharply during the Great Recession, business fixed investment (BFI) recovered in 2010, but investment was again quite low in 2015 and 2016. This slowdown was driven in part by the decline of oil prices that led to a significant contraction in the oil drilling industry. Since then, growth has ...

How Much Risk Do Variable Annuity Guarantees Pose to Life Insurers?
Over the past two decades, guarantees that protect variable annuities? balances when their underlying investments perform poorly have become quite popular. Collectively, these guarantees can pose a sizable risk to life insurers. This article explores the different types of variable annuity guarantees, the extent of the risk they pose to insurers, and the practices used by insurers to mitigate against such risk.
