We use regular vine (r-vine), canonical vine (c-vine) and drawable vine (d-vine) copulas to examine the dependence risk characteristics of three 20-stock portfolios from the retail, manufacturing and gold-mining equity sectors of the Australian market in periods before, during and after the...

Crisis shocks often lead to changes in the interdependence across stock markets, and thus risk assessment and management. This paper investigates the extent to which the global financial crisis of 2008-2009, which was triggered by the US subprime crisis in 2007, and the European debt crisis...

We employ multifractal detrended fluctuation analysis (MF-DFA) to provide the first look at the efficiency of forex markets during the initial period of ongoing COVID-19 pandemic, which has disrupted the financial markets globally. We use high frequency (5-min interval) data of six major...

During and after the 2008-2009 global financial crisis, the growth cycle of Vietnam’s economy has shifted from an average annual growth rate of 7%-8% to an average annual growth rate of 5%-6% with a high level of macroeconomic instability and uncertainty from 2009 till 2016. Related studies...

We propose a stochastic spanning approach to assess whether a traditional portfolio of stocks and bonds spans augmented portfolios including commodities, foreign exchange, and real estate. We empirically show that in all seven portfolio combinations, the augmented portfolio is not spanned by the...

We examine the relationship between broker network connectivity and stock returns in an order-driven market. Considering all stocks traded in Borsa Istanbul between January 2006 and November 2015, we estimate the monthly density, reciprocity and average weighted clustering coefficient as proxies...

We propose a stochastic spanning approach to assess whether a traditional portfolio of stocks and bonds spans augmented portfolios including commodities, foreign exchange, and real estate. We empirically show that in all seven portfolio combinations, the augmented portfolio is not spanned by the...

We investigate the dynamics of return and liquidity (co)jumps for three of the most traded emerging market currencies vis-à-vis US dollar. We find that an increase in the average bid-ask spread significantly reduces the duration between consecutive return jumps, while liquidity and volatility...

We introduce a continuous time model for stock prices in a general factor representation with the noise driven by a geometric Brownian motion process. We derive the theoretical hitting probability distribution for the long-until-barrier strategies and the conditions for statistical arbitrage. We...

In this article, we investigate the causality links between CO2 emissions, foreign direct investment, and economic growth using dynamic simultaneous-equation panel data models for a global panel of 54 countries over the peri-od 1990–2011. We also implement these empirical models for 3 regional...
