Based on the APARCH model and two outlier detection methods, we computereliable time series of volatility asymmetry for 49 countries with relatively few ob-servations. Results show a steady increase in the asymmetry over the years for mostcountries. We nd that economic development and market...

Based on the APARCH model and two outlier detection methods, we compute reliable time series of volatility asymmetry for 49 countries with relatively few observations. Results show a steady increase in the asymmetry over the years for most countries. We find that economic development and market...

This paper modelled the volatility persistence and asymmetry of naira-dollar exchange rate in interbank and Bureau de Change (BDC) using monthly data between January 2004 and November 2017. The study employed Generalized Autoregressive Conditional Heteroscedasticity [GARCH (1,1)], Thresh- old...

The recent financial crisis renewed concerns about a possible destabilizing impact of derivatives trading. Despite a very active research, the question whether or not derivatives tend to destabilize financial markets has not yet been answered to satisfaction. This contribution aims to revise the...

We examine the role of competing exchanges to restore price parity following currency shocks during 2008, a year characterized by dramatic currency volatility. Burdens on the NYSE and home market to restore price parity for cross-listed stocks are more dynamic than previously thought....

This paper develops a model of exchange rate dynamics that takes into account speculative positions in foreign and domestic equities in addition to the "standard" positions in short-term riskless deposits. The modeling of cross-country stock holdings is motivated by evidence that a large and...

This study aims to investigate the dynamic conditional correlation and volatility spillover between the conventional and Islamic stock markets in developed and emerging countries in order to develop better portfolio and asset allocation strategies. We used both multivariate GARCH (MGARCH) and...

Do traders who place orders early necessarily trade first? In some trading systems, the answer is no. Such systems often give preference to larger orders instead. Institutional arrangements such as quot;preferencingquot; and quot;payment-for-order flowquot; also violate time priority. In an...

In 2008, the S&P 500 experienced a drawdown of about 50% from peak to trough. Many assets which are typically considered effective equity diversifiers also faced precipitous losses. In stark contrast, volatility levels as measured by VIX experienced significant increases and in 2008 repeatedly...

This paper describes a way to model a seasonally and irregularly peaking price dynamics, as that originated in commodity and energy markets, using a system of coupled nonlinear stochastic differential equations. The specific case of an electric power market is used to show which microeconomic...
