Our paper investigates the impact of COVID-19 on stock markets across G7 countries (the US, the UK, Canada, France, Germany, Italy and Japan) and sectors (Consumer Goods, Consumer Services, Financials, Healthcare, Industrials, Materials, Oil & Gas, Technology, Telecommunications and Utilities)...

Using a novel method to separate US community banks over the 1984-2013 period from their non-community counterparts we compare the two bank types on the basis of cost efficiency. We decompose cost efficiency into a persistent and a residual component; the former capturing the market structure...

Are Islamic banks inherently more stable than conventional banks? We address this question by applying a survival analysis based on the Cox proportional hazard model to a comprehensive sample of 421 banks in 20 Middle and Far Eastern countries from 1995 to 2010. By comparing the failure risk for...

This paper shows that generalizing the heterogeneous autoregressive model (HAR) with realized (co)variances and semi-(co)variances from the index leads to more accurate volatility forecasts. To circumvent the effects of the market microstructure noise arising from using high sampling...

We examine the synchronization of European Union (EU) financial markets before and during the recent financial crisis. A DCC-GARCH framework captures dynamic correlations and a Markov-Switching framework captures regime changes. For the 27 nations of the EU, we formulate characteristics of the...

We examine efficiency in Islamic and conventional banking systems in the Gulf Cooperation Council (GCC) region (2004-2007) using financial ratio analysis (FRA) and data envelopment analysis (DEA). We find the two approaches are complementary in terms of the information they provide. From the...

This paper examines how efficiency dynamics of Islamic and conventional banks compare and how they are converging across different countries. We employ both parametric and non-parametric methods to analyse a panel of Islamic and conventional banks from 23 countries during the period 1999 to...

This paper examines how efficiency dynamics of Islamic and conventional banks compare and how they are converging across different countries. We employ both parametric and non-parametric methods to analyse a panel of Islamic and conventional banks from 23 countries during the period 1999 to...

This paper considers 100 stocks from 10 sectors over the period 2000 to 2010 to examine the impact of market conditions, sector type and horizon on the forecasting performance of various volatility models. Out-of-sample forecasts are generated with standard daily GARCH and with ARFIMA/HAR models...
