This study investigates the relationship between the return on a stock index and its volatility using high frequency data. Two well-known hypotheses are reexamined: the leverage effect and the volatility feedback effect hypotheses. In an analysis of the five-minute data from the Samp;P500 index,...

We develop a conditional version of the consumption capital asset pricing model (CCAPM) using the conditioning variable from the cointegrating relation among macroeconomic variables (dividend yield, term spread, default spread, and short-term interest rate). Our conditioning variable has a...

We develop a conditional version of the consumption CAPM using the conditioning variable derived from the cointegrated relationship among macroeconomic variables (dividend yield, term spread, default spread, and short-term interest rate). Our conditioning variable has a strong power to predict...

This paper uses daily sovereign credit default swap (CDS) prices to investigate how the credit risks of major Latin American reference entities are interlinked. Our empirical findings suggest that the underlying creditworthiness of nations is reflected in the direction of Granger causality and...

<section xml:id="fut21660-sec-0001"> We present a theoretical model of option‐implied preferences with model uncertainty. An option‐implied risk aversion function with model uncertainty has a higher and a steeper level of risk aversion than an investor without model uncertainty. Based on the theoretical model, we try to...</section>
