This paper studies a novel approach for managing macroeconomic volatility in commodity exporting countries. As part of this study, we develop a sovereign risk management model in the context of an Asset-Liability Management (ALM) framework. Our first contribution is an extension of the...

The current financial market crisis has impressively demonstrated the importance of an effective credit risk management for financial institutions. At the same time, the use and the valuation of credit derivatives has been widely criticised as a result of the crisis. Over the past decade, credit...

This paper investigates whether bond fund managers with credit rating experience outperform their peers. We document that bond fund managers who previously worked in credit rat- ing agencies on average create higher risk-adjusted returns than their peers by 11-16 bps per month, with better...

We discuss how to build ETF risk models. Our approach anchors on i) first building a multilevel (non-)binary classification/taxonomy for ETFs, which is utilized in order to define the risk factors, and ii) then building the risk models based on these risk factors by utilizing the heterotic risk...

We show that the quotient of Levy processes of jump-diffusion type has a fat-taileddistribution. An application is to price theory in economics, with the result that fat tails ariseendogenously from modeling of price change based on an excess demand analysis resulting in aquotient of arbitrarily...

Aim/purpose - In this paper, a market volatility-robust portfolio composition framework under the modified Markowitz’s approach with the use of sampling methods is developed in order to improve the allocation efficiency for a portfolio of financial instruments formulation procedure at an...

This paper suggests using portfolio management methods in policy planning models as a practical tool for determining optimal policy under model parameter uncertainty. We suggest that in addition to calculating the standard policy return estimates, policy options should also be analyzed from the...

This article aims to extend evaluation of the classic multifactor model of Carhart (1997) for the case of global equity indices and to expand analysis performed in Sakowski et. al. (2015). Our intention is to test several modifications of these models to take into account different dynamics of...

Using high-frequency data, we decompose the time-varying beta for stocks into beta for continuous systematic risk and beta for discontinuous systematic risk. Estimated discontinuous betas for S&P500 constituents between 2003 and 2011 generally exceed the corresponding continuous betas. We...

This paper investigates the merits of high-frequency intraday data when forming minimum variance portfolios and minimum tracking error portfolios with daily rebalancing from the individual constituents of the S&P 100 index. We focus on the issue of determining the optimal sampling frequency,...
