Worst-case risk of a portfolio
Numerical calculation portfolio risk return on assets average semidefinite programming
2015/8/11
We show how to compute in a numerically efficient way the maximum risk of a portfolio, given uncertainty in the means and covariances of asset returns. This is a semidefinite programming problem, and ...
Globalization of Corporate Risk Taking
Corporate risk-taking global liquidity capital fl ows fi nancial crises multinational companies
2014/3/18
We explore how the interconnected nature of global finance affects corporate risk taking. We show that a common global factor known to be associated with fluctuations in cross-border...

2014/6/23
We analyze theoretically banks choice of organization and leverage in branches or subsidiaries in the presence of economic and Önancial synergies, government bailouts and bankruptcy costs. We com...
The availability of credit varies over the business cycle through shifts in the leverage of financial intermediaries. Empirically, we find that intermediary leverage is negatively aligned ...
Speculation and Risk Sharing with New Financial Assets
Speculation and Risk New Financial Assets
2014/9/10
I investigate the effect of financial innovation on portfolio risks when traders have belief disagreements. I decompose traders’ average portfolio risks into two components: the uninsurable variance, ...
We explore the extent to which Önancial conditions áuctuate due to áuctuations in leverage, and thereby connect the recent literature on banking crises with the ìleverage e§ectîof Fisher Bla...
Complete duality for quasiconvex dynamic risk measures on modules of the $L^{p}$-type
quasiconvex functions dual representation complete duality L0-modules dynamic risk measures quasiconvex risk measures
2012/3/2
We provide a dual representation of quasiconvex conditional risk measures $% \rho $ defined on $L^{0}$ modules of the $L^{p}$ type. This is a consequence of more general result which extend the usual ...
Set-Valued Dynamic Risk Measures
dynamic risk measures transaction costs set-valued risk measures time consistency dual representation
2012/3/2
The paper concerns primal and dual representations as well as time consistency of set-valued dynamic risk measures. Set-valued risk measures appear naturally when markets with transaction costs are co...
This paper characterizes downside risk aversion in a simple and intuitive manner. It is shown that using this characterization one can simplify considerably a theorem by Jindapon (2010) relating to gr...

Continuous elimination of the acreage of orchards in Slovakia has a negative impact on the overall fruit production. Improvement of the conditions could be achieved by introducing new technological sy...
Analytic Loss Distributional Approach Model for Operational Risk from the alpha-Stable Doubly Stochastic Compound Processes and Implications for Capital Allocation
Operational Risk Loss Distributional Approach Doubly stochastic Poisson Process -Stable Basel II Solvency II
2011/3/23
Under the Basel II standards, the Operational Risk (OpRisk) advanced measurement approach is not prescriptive regarding the class of statistical model utilised to undertake capital estimation. It has ...
