Deviations from covered interest parity in the emerging markets after the global financial crisis
(Elsevier, 2023-03-25) Geyikçi, U. B.; Özyıldırım, Süheyla
In this paper, we focus on six emerging market economies to study the magnitude of systemic and persistent deviations from covered interest parity (CIP) using daily data between January 2010 and July 2018. We show the significant role of local factors, particularly credit and liquidity risk, in explaining sustained CIP deviations in these markets. Our findings suggest that the impact of credit risk on CIP deviations in emerging market economies may take two forms. In low-carry currencies, the well-known mechanism for credit risk operates so that the increase in credit risk exacerbates CIP deviations. Conversely, in high-carry currencies, the high usage of foreign exchange swaps makes swap rates react more than domestic rates, which causes CIP to decrease. We also present evidence that cost of illiquidity is an important driver to explain CIP deviations. We demonstrate that increased liquidity in emerging market currencies is not as large to prevent CIP deviations.

Set-valued shortfall and divergence risk measures
(World Scientific Publishing, 2017) Ararat, C.; Hamel, A. H.; Rudloff, B.
Risk measures for multivariate financial positions are studied in a utility-based framework. Under a certain incomplete preference relation, shortfall and divergence risk measures are defined as the optimal values of specific set minimization problems. The dual relationship between these two classes of multivariate risk measures is constructed via a recent Lagrange duality for set optimization. In particular, it is shown that a shortfall risk measure can be written as an intersection over a family of divergence risk measures indexed by a scalarization parameter. Examples include set-valued versions of the entropic risk measure and the average value at risk. As a second step, the minimization of these risk measures subject to trading opportunities is studied in a general convex market in discrete time. The optimal value of the minimization problem, called the market risk measure, is also a set-valued risk measure. A dual representation for the market risk measure that decomposes the effects of the original risk measure and the frictions of the market is proved.
