We analyze the impact of the estimation frequency - updating parameter estimates on a daily, weekly, monthly or quarterly basis - for commonly used GARCH models in a large-scale study, using more than twelve years (2000-2012) of daily returns for constituents of the S&P 500 index. We assess the...

Expected Shortfall (ES) has been widely accepted as a risk measure that is conceptually superior to Value-at-Risk (VaR). At the same time, however, it has been criticized for issues relating to backtesting. In particular, ES has been found not to be elicitable which means that backtesting for ES...

Risk diversification is the basis of insurance and investment. It is thus crucial to study the effects that could limit it. One of them is the existence of systemic risk that affects all the policies at the same time. We introduce here a probabilistic approach to examine the consequences of its...

The Operational Risk Advanced Measurement Approach requires financial institutions to use scenarios to model these risks and to evaluate the pertaining capital charges. Considering that a banking group is composed of numerous entities (branches and subsidiaries), and that each one of them is...

Generally, in the financial literature, the notion of quadratic VaR is implicitly confused with the Delta-Gamma VaR, because more authors dealt with portfolios that contained derivatives instruments. In this paper, we postpone to estimate both the expected shortfall and Value-at-Risk of a...

This paper examines how exchange rate volatility and Korean banks’ foreign exchange liquidity mismatches interacted with each other during the Global Financial Crisis, and whether the vulnerability stemming from this interaction has been reduced since then. Structural and cyclical changes...

The degree of an economy’s monetization, which has an important implication on economic growth, can be affected by the conduct of monetary policy, financial sector reform, and episodes of financial crises. The paper finds that monetization--measured by the ratio of broad money to nominal...

We demonstrate empirically that not all capital flows influence exchange rates equally: Capital flows induced by foreign investors’ stock market transactions have both an economically significant and a permanent impact on exchange rates, whereas capital flows induced by foreign...
