Book Description
For most of the 20th century commodity prices fell in real terms. Prices of metals, energy and food became so low that they were almost irrelevant to developed world consumers. Since 2003 prices have risen sharply, and have become so high they have been blamed for recessions, civil unrest and even revolutions. Although increased speculation in commodity markets has probably played a role, the fundamental factors of supply and demand continue to form the most important determinant of commodity prices. Price rises have been caused by 'scarcity' caused by rapid demand growth from newly affluent consumers in the developing world, meeting a supply that has struggled to respond. Understanding current and future scarcity in commodities therefore helps us predict and warn of further price spikes. This thesis studies all three major commodity groups, examining existing ways to measure scarcity and proposing new ones. Firstly we study the base (industrial) metals. We examine the 'theory of storage', which explains price and price volatility in terms of the quantity stored in inventory, a key measure of scarcity. Secondly we study energy markets. Electricity cannot be stored, so the 'theory of storage' cannot be applied. We note an alternative measure of scarcity which allows us to apply a modified theory of storage to electricity. We also examine its applicability to another key energy commodity, crude oil. Finally we examine scarcity in the agricultural products. Here we have inventory data, providing short-term scarcity information, but unlike for energy and metals, we have no concept of reserves, being that resource known but remaining in the ground, which provides longer-term scarcity information. Instead, we propose and examine several other ways to measure scarcity.

Book Description
How does a commodity market adjust to a temporary scarcity shock which causes a shift in the slope of the futures price curve? We find long-run relationships between spot and futures prices, inventories and interest rates, which means that such shocks lead to an adjustment back towards a stable equilibrium. We find evidence that the adjustment is somewhat consistent with well-known theoretical models, such as Pindyck (2001); in other words, spot prices rise and then fall, while inventories are used to absorb the shock. Importantly, the pace and nature of the adjustment depends upon whether inventories were initially high or low, which introduces significant nonlinearities into the adjustment process.

Book Description
Commodities have become an important component of many investors' portfolios and the focus of much political controversy over the past decade. This book utilizes structural models to provide a better understanding of how commodities' prices behave and what drives them. It exploits differences across commodities and examines a variety of predictions of the models to identify where they work and where they fail. The findings of the analysis are useful to scholars, traders and policy makers who want to better understand often puzzling - and extreme - movements in the prices of commodities from aluminium to oil to soybeans to zinc.

Book Description
In an era of abundance, at least part of humanity has stopped thinking about the future provision of basic vital resources such water, energy and food. Storage actions, with all their variants whether real or imagined, are sources of innovation in the provision and treatment of crucial resources. This book deals with cases of water, food, energy and biodiversity storage as a response to a new era of scarcity. Examining multilevel storage policies, consumers’ practices and local organisations, author Giorgio Osti explores a variety of examples such as the need to stock agriculture produce, the industry and practices of food conservation, the role of artificial water basins in controlling floods and droughts and the development of batteries able to compensate for the intermittence of renewable energy sources. Storage and self-sufficiency can be achieved in many technical ways, at different territorial levels and according to different policies or philosophies. Being more a grasshopper or an ant - the two extreme positions - depends not only on the technologies available but also on different analyses of the environment and different attitudes to the future. This book offers an environmentalist perspective that uncovers hidden or absent activities of ultramodern societies that will be useful to students of environmental sociology as well as those researching and studying at the interface of environmental studies and geography.

Book Description
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.

Book Description
We revive in this paper the empirical relevance of the competitive storage model by taking a holistic approach to food commodity prices. We augment the seminal Deaton and Laroque (1992, 1996) model by incorporating more comprehensive and realistic supply and demand factors: output and demand trends, shocks to the yield, and time-varying interest rates. While the computational burden increases exponentially, the augmented model succeeds in replicating all four key patterns of food commodity prices. Our simulation and comparative statics also show that (i) the long-run declining trend of food prices may come to a halt or even reverse due to the shifting balance between supply and demand; (ii) short-run price fluctuations are mainly attributable to sizeable, though low-probability, shocks to output such as inclement weather; and (iii) the impact of monetary policy, though small in normal times, is nonlinear and asymmetric, and can become large if the real rate passes a certain threshold.
