The link between commodities prices and the business cycle, including variables such as real GDP, industrial production, unemployment, inflation, and market uncertainty, has often been debated in the macroeconomic literature. To quantify the impact of commodities on the economy, one can distinguish different modeling approaches. First, commodities can be represented as the pinnacle of cross-sectional financial asset prices. Second, price fluctuations due to seasonal variations, dramatic market changes, political and regulatory decisions, or technological shocks may adversely impact producers who use commodities as input. This latter effect creates the so-called "commodities risk". Additionally, commodities price fluctuations may spread to other sectors in the economy, via contagion effects. Besides, stronger investor interest in commodities may create closer integration with conventional asset markets; as a result, the financialization process also enhances the correlation between commodity markets and financial markets.Our objective in this book, Risk Factors and Contagion in Commodity Markets and Stocks Markets, lies in answering the following research questions: What are the interactions between commodities and stock market sentiment? Do some of these markets move together overtime? Did the financialization in energy commodities occur after the 2008 Global Financial Crisis? These questions are essential to understand whether commodities are driven only by their fundamentals, or whether there is also a systemic component influenced by the volatility present within the stock markets.

The rapid advancement in encryption and network computing gave birth to new tools and products that have influenced the local and global economy alike. One recent and notable example is the emergence of virtual currencies, also known as cryptocurrencies or digital currencies. Virtual currencies, such as Bitcoin, introduced a fundamental transformation that affected the way goods, services, and assets are exchanged. Virtual currencies are experiencing an increasing popularity in the financial markets and in portfolio management as can be classified as financial asset or commodities on a scale from pure medium of exchange advantages to pure store of value advantages. As a result of its distributed ledgers based on blockchain, cryptocurrencies offer some unique advantages to the economy, investors, and consumers, but also pose considerable risks to users and challenges for regulators when fitting the new technology into the old legal framework. Bitcoin for example may be useful in risk management and ideal for risk-averse investors in anticipation of negative shocks to the market. The core objective of this proposed book is to provide a comprehensive discussion on the important issues related to cryptocurrencies ranging from pricing, financial, legal to technological aspects.
