In previous studies, high-frequency data has been used to improve portfolio allocation by estimating the full realized covariance matrix. In this paper, we show that strategies using high-frequency data for measuring and forecasting univariate realized volatility alone can already generate...

If the creditworthiness of a counterparty is a derivative of a commodity price, there is the potential to have right- or wrong-way exposures in respective commodity transaction. Identifying them is important, because otherwise credit costs might be inadequately calculated and wrong incentives...

Most asset pricing models postulate a positive relationship between a stock portfolio's expected returns and risk, which is often modeled by the variance of the asset price. This paper uses GARCH-in-mean models to examine the relationship between mean returns on a stock portfolio and its...

This study investigates the relationship among interest rates on the long-term governments bonds of five industrialized countries. Both standard and new unit root tests are applied, all of which confirm the presence of exactly one unit root. New cointegration tests are also applied to these...

Interest rate swaps are the most popular financial derivatives used by US firms. In this paper, the effects of swap usage on corporate financing decisions are empirically examined. Based on a dynamic capital structure theoretical model, we employ a seemingly unrelated regression model with a...

This study utilizes contemporaneously sampled survey data on the expectations of U.S. and Japanese investors regarding future levels of the DJIA and the NIKKEI stock indices. The survey covers the period 1989-1999. The expectation data is used to compute direct tests of investor rationality and...

Using long-run data and a VAR approach, the study investigates whether US and UK stock markets have experienced excessively volatile prices and excessively high returns. Present value models, developed in a constant and non-constant risk CAPM framework, are used as benchmarks with which to...

In this paper we present and extend the approach of Bollerslev and Zhang (2003) for quot;realizedquot; measures and co-measures of risk in some classical asset pricing models, such as the Capital Asset Pricing Model (CAPM) of Sharpe (1964) and the Arbitrage Pricing Theory (APT) model by Ross...

In this paper we present simulations of economic performance of the Polish economy based on a quarterly econometric model. The model consists of 22 stochastic equations, which link the financial market with the real economy. The purpose of the research is to present effects of changes to...

After more than a decade of existence, crypto-currencies may now be considered an important class of assets presenting some unique appealing characteristics but also sharing some features with real financial assets. This paper provides a comprehensive statistical analysis of the six most...
