The autocorrelations of log-squared, squared, and absolute financial returns are often used to infer the dynamic properties of the underlying volatility. This article shows that, in the context of long-memory stochastic volatility models, these autocorrelations are smaller than the...

In this paper, we consider the role of imperfect competition in explaining the relative price of non-traded to traded goods within the Balassa-Samuelson framework. Under imperfect competition in the two sectors, relative prices depend on both productivity differentials and mark-up differentials....

Banking competition induces an efficient outcome but may also induce risk-taking behaviour that reduces solvency. This study examines the relationship between efficiency and solvency in banking at the empirical level. The empirical findings support that greater efficiency with respect to a...

We study whether the credit default swap (CDS) spreads of firms reflect the risk from climate transition. We first construct a climate transition risk (CTR) factor by using information on the vulnerability of a firm's value to the transition to a low-carbon economy. We then document how this...

We assess the role played by exchange rates in buffering or amplifying the propagation of shocks across international equity markets. Using copula functions we model the joint dependence between exchange rates and two global equity markets and, from a copula framework, we obtain the conditional...

Transitioning to a low-carbon economy involves risks for the value of financial assets, with potential ramifications for financial stability. We quantify the systemic impact on financial firms arising from changes in the value of financial assets under three climate transition scenarios that...

Renewable energy deployment as an alternative to traditional energy sources is the cornerstone of the emission-reduction energy policies that aim to facilitate the transition to a low-carbon economy. This transition poses risks and opportunities for companies with business models that rely...

This paper examines the relationship between oil prices and the US dollar exchange rate using detrended cross-correlation analysis. For a wide set of currencies in the periods before and since the onset of the recent global financial crisis, we characterized the oil price–exchange rate...

This paper examines the dependence structure between the emerging stock markets of the BRICS countries (Brazil, Russia, India, China and South Africa) and influential global factors (the S&P 500 index, the commodity markets, the global stock market uncertainty and the US economic policy...

This paper examines the dependence structure between the emerging stock markets of the BRICS countries and influential global factors. Using the quantile regression approach, our results for the period from September 1997 to September 2013 show that the BRICS stock markets exhibit dependence...
