Heterogeneity in the Internationalization of R&D: Implications for Anomalies in Finance and Macroeconomics
(2017-10-17)
Empirical evidence suggests that investments in research and development (R&D) by older and larger firms are more spread out internationally than R&D investments by younger and smaller firms. In this paper, I explore the ...
Level and Slope of Volatility Smiles in Long-Run Risk Models
(2017-10-16)
We propose a long-run risk model with stochastic volatility, a time-varying mean reversion level of volatility, and jumps in the state variables. The special feature of our model is that the jump intensity is not affine ...
Optimal Taxes on Capital in the OLG Model with Uninsurable Idiosyncratic Income Risk
(2018-02-09)
We characterize the optimal linear tax on capital in an Overlapping Generations model with two period lived households facing uninsurable idiosyncratic labor income risk. The Ramsey government internalizes the general ...
Volatility-of-Volatility Risk
(2018-05-01)
We show that time-varying volatility of volatility is a significant risk factor which affects the cross-section and the time-series of index and VIX option returns, beyond volatility risk itself. Volatility and ...
Only Time will Tell: A Theory of Deferred Compensation
(2018-08-09)
This paper provides a complete characterization of optimal contracts in principal-agent settings where the agent's action has persistent effects. We model general information environments via the stochastic process of the ...
Pricing Sin Stocks: Ethical Preference vs. Risk Aversion
(2018-06-14)
We develop a model that reproduces the average return and volatility spread between sin and non-sin stocks. Our investors do not necessarily boycott sin companies. Rather, they are open to invest in any company while trading ...
Networks in Risk Spillovers: A Multivariate GARCH Perspective
(2018-08-01)
We propose a spatiotemporal approach for modeling risk spillovers using time-varying proximity matrices based on observable financial networks and introduce a new bilateral specification. We study covariance stationarity ...
Asset Pricing in OLG Economies With Borrowing Constraints and Idiosyncratic Income Risk
(2018-09-17)
This paper analyzes how the combination of borrowing constraints and idiosyncratic risk affects the equity premium in an overlapping generations economy. I find that introducing a zero-borrowing constraint in an economy ...
Idiosyncratic Volatility Puzzle: The Role of Assets' Interconnections
(2018-08-08)
The paper investigates the determinants of the idiosyncratic volatility puzzle by allowing linkages across asset returns. The first contribution of the paper is to show that portfolios sorted by increasing indegree computed ...
A Tale of One Exchange and Two Order Books: Effects of Fragmentation in the Absence of Competition
(2018-10-01)
Exchanges nowadays routinely operate multiple, almost identically structured limit order markets for the same security. We study the effects of such fragmentation on market performance using a dynamic model where agents ...
