We employ several copula functions to capture conditional and tail dependence during periods of extreme volatility and reverse conditions between shipping, financial, commodity and credit markets. We find that shocks in the shipping market coincide with dramatic changes in other markets and...

We employ a wavelet approach and conduct a time-frequency analysis of dynamic correlations between pairs of key traded assets (gold, oil, and stocks) covering the period from 1987 to 2012. The analysis is performed on both intra-day and daily data. We show that heterogeneity in correlations...

This study attempts to discover the nexus between crude oil price fluctuation after heavy oil upgrading and stock returns of petroleum companies in the U.S. Stock Exchange for the years 2008 to 2018. One of the methods of upgrading heavy crude oil is to extract asphaltene from crude oil....

The rising uncertainty in financial markets in the last 40 years has led to the creation of new financial indices that will enable these uncertainties to be defined and measured. For this purpose, the first volatility index created was the VIX Index as an indicator of uncertainty in the stock...

We measure the return connectedness in US policy uncertainty, equity and commodity market between January 1990 to December 2015, with a specific focus on the net spillover transmission from one assets class to another asset class. Applying Diebold and Yilmaz (2012, 2014), we perform both static...

New Keynesian Phillips Curves (NKPC) have been exten-sively used in the analysis of monetary policy, but yet there are a number of issues of concern about how they are estimated and then related to the underlying macro-economic theory. The first is whether such equations are identified. To check...
