This paper studies the volatility of electricity spot prices in the Nordic market (Sweden, Finland, Denmark, and Norway) under regime switching. Utilizing Markov-switching GARCH (Generalized Autoregressive Conditional Heteroskedasticity) models, we provide strong evidence of nonlinear regime...

The cryptocurrency market, known for its inherent volatility, has been significantly influenced by external shocks, particularly during periods of global crises such as the COVID-19 pandemic and the Russia-Ukraine war. This study investigates the volatility of the top seven cryptocurrencies by...

This study endeavors to explore the shock-transmission mechanism between Trade Policy Uncertainty (TPU) and the volatility inherent in the Gulf Cooperation Council (GCC) Islamic stock markets by employing the novel Quantile Vector Auto Regression (QVAR) with "Extended Joint" and "Frequency"...

Forward-looking metrics of uncertainty based on options-implied information should be highly predictive of equity market returns in accordance with asset pricing theory. Empirically, however, the ability of the VIX, for example, to predict returns is statistically weak. In contrast to other...

Deviation of an asset price from its fundamental value, commonly referred to as a price bubble, is a well-known phenomenon in financial markets. Mathematically, a bubble arises when the deflated price process transitions from a martingale to a strict local martingale. This paper explores price...

This study examines the out-of-sample predictability of expected skewness of oil price returns, which serves as a metric for global future risks, as we show statistically through the association with crises of different nature, for stock returns of 10 (8 advanced plus two emerging) countries...

This study examines the integrated impacts of cyberattacks, geopolitical, and financial market volatility on rare earth markets during the 2014-2024 period, using Time-Varying Parameter Vector Autoregression and wavelet analysis. By bridging critical gaps in the literature, this research...

This paper investigates the cyclicality of international reserves and their role in macroeconomic stabilization. We challenge two widely held assumptions: (1) central banks typically manage IR counter-cyclically—accumulating reserves during booms and drawing them down during downturns; and (2)...

This article provides a comprehensive analysis of labor earnings volatility in Brazil between 2012 and 2023. During this period, Brazil's economy experienced intense economic growth followed by large recessions, allowing us to assess changes in volatility over the business cycle. In addition,...

This study examines the relationship between sovereign spreads and banks in terms of risk transmission, using the seven largest Italian banks as a sample over the period from 2003 to 2023. Our objective is to quantify and compare volatility spillovers, and to investigate whether bank-specific...

This paper investigates the relationship among transaction taxes, high-frequency trading (HFT), and market quality. We use the agent-based modeling (ABM) approach to dynamically assess the impact of transaction taxes on market quality with and without high-frequency trading. Preliminary tests...

While artificial intelligence (AI) adoption holds the potential to enhance business operations through improved forecasting and automation, its relation with average productivity growth remain highly heterogeneous across firms. This paper shifts the focus and investigates the impact of...

The evidence of financial globalization and the rapid and uniform contagion that it entails among the different international financial markets, have been exposed after the 2008 crisis outbreak, as well as the different chapters of financial stress that have been experienced since then, such as...
