In order to determine the Colombian and U.S stock market's structural dependence, losses of Col20, Dow Jones, and Standard & Poors 500 were use as variables. Semiparametric Copula-based Multivariate Dynamic (SCOMDY) proposed by Chen & Fan (2006) was used as methodology. It was found that the...

Heterogeneous-agents asset pricing theories imply that stockholders' consumption has the first-order effect on equity premium. Motivated by these theories, we evaluate the performance of the conditional CCAPM in explaining time-variation in market returns and cross-sectional variation in...

This research focuses on the estimation of measures of rare disaster concerns from option prices. We propose a new smile construction approach to obtain the required continuum of implied volatilities from discretely sampled observations that are affected by microstructure noise. We extrapolate...

This study provides an in-depth analysis of how to estimate risk-neutral moments robustly. A simulation and an empirical study show that estimating risk- neutral moments presents a trade-off between (1) the bias of estimates caused by a limited strike price domain and (2) the variance of...

Although not a formal pricing consideration, gap risk or hedging errors are the norm of derivatives businesses. Starting with the gap risk during a margin period of risk of a repurchase agreement (repo), this article extends the Black-Scholes-Merton option pricing framework by introducing a...

Para determinar la dependencia estructural entre los mercados bursátiles colombiano y estadounidense, se usaron las pérdidas de los índices Col20, Dow Jones y Standard & Poors 500 como variables. La metodología desarrollada siguió los lineamientos de los modelos de dinámica multivariados,...

This paper examines the impact of intraday periodicity on forecasting realized volatility using a heterogeneous autoregressive model (HAR) framework. We show that periodicity inflates the variance of the realized volatility and biases jump estimators. This combined effect adversely affects...
