Book Description
We show that the innovation in the risk-neutral probability of large downward and upward jumps in oil prices has a considerable predictive power for important economic indicators such as GDP growth, consumption growth, and total investment. In addition, we observe that the upside jump risk probability is a significant predictor of stock market index return and the returns of oil futures. Furthermore, the upside jump probability is a significant and relatively strong predictor of oil market fundamentals including inventory growth, demand growth, and OPEC's production growth. Upside jump risk is also a driver of the cross-section of stock returns before the U.S. oil production increase in 2011. The average monthly return for the high-low upside jump risk exposure portfolio is -0.94% and -1.13%, using the 1996-2014 and 1996-2011 time periods respectively. The implications of the variance risk for the cross-section of stock returns vanishes after controlling for the large upside and downside jump risks. The shale revolution and considerable increase of the US oil production have killed the effect of upside risk premium after 2011. During the sub-period 2011-2014, the variance risk premium gets significant again, like it was before 2000.

Book Description
This paper investigates model dynamics and risk premia in the short term market for crude oil futures. Stochastic volatility models, with and without jumps, are estimated using data on both futures and option prices. As an economic application we apply the estimated models to the pricing of crude oil variance swaps and an evaluation of the associated variance risk premium. The empirical results point to a positive return risk premium attached to diffusive stochastic volatility while there is not strong evidence of jump risk being priced in the market. Negative volatility and variance risk premia stand out as a robust and significant feature of the data. Jumps play a minor role for representing data and the jump risk component in both variance swaps and variance risk premia is small. Finally, a non-affine model that allows for level dependent volatility of volatility is found to have the best fit to data.

Book Description
This dissertation consists of two essays on crude oil futures and options markets. The first essay investigates whether aggregate risk aversion and risk premiums in the crude oil market co-vary with the level of speculation. Using crude oil futures and option data, I estimate aggregate risk aversion in the crude oil market and find that it is signi ficantly lower after 2002, when speculative activity started to increase. Using speculation index as a state variable, risk premiums implied by the state-dependent risk aversion estimates confi rm the negative correlation between speculative activity and risk premiums, and indicate that risk premiums in the crude oil market are on average lower and more volatile after 2002. These findings suggest that index-fund investors who demand commodity futures for the purpose of portfolio diversi fication are willing to accept lower compensation for their positions. Estimated state-dependent risk premiums have substantial predictive power for subsequent futures returns and outperform commonly used predictors. The second essay exams the economic importance of jumps, jump risk premiums, and dynamic jump intensities in crude oil futures and options markets. Existing pricing models for crude oil options are computationally intensive due to the presence of latent state variables. Using a panel data of crude oil futures and options, I implement a class of computationally e fficient discrete-time jump models. I find that jumps account for about half of the total variance in crude oil futures and options prices, and a substantial part of the risk premiums is due to jumps. Jumps are large and rare events in crude oil futures and options markets. The main role of jumps and jump risk premiums in crude oil futures and options markets is to capture excess kurtosis in the data. These findings suggest that it is critical to include jumps in pricing models for crude oil futures and options, and there is strong evidence in favor of time-varying jump intensities.

Book Description
Crude oil prices have been on a run-up spree in recent years. Their dynamics were characterized by high volatility, high intensity jumps, and strong upward drift, indicating that oil markets were constantly out-of-equilibrium. An explanation of the oil price process in terms of the underlying fundamentals of oil markets and world economy was provided, viewing pressure on oil prices mainly as a result of rigid crude oil supply and an expanding world demand for crude oil. A change in the oil price process parameters would require a change in the underlying fundamentals. Market expectations, extracted from call and put option prices, anticipated no change, in the short term, in the underlying fundamentals. Markets expected oil prices to remain volatile and jumpy, and with higher probabilities, to rise, rather than fall, above the expected mean.

Book Description
Crude oil derivatives form an important part of the global derivatives market. In this paper, we focus on Asian options which are favoured by risk managers being effective and cost-saving hedging instruments. The paper has both empirical and theoretical contributions: we conduct an empirical analysis of the crude oil price dynamics and develop an accurate pricing setup for arithmetic Asian options with discrete and continuous monitoring featuring stochastic volatility and discontinuous underlying asset price movements. Our theoretical contribution is applicable to various commodities exhibiting similar stylized properties. We here estimate the stochastic volatility model with price jumps as well as the nested model with omitted jumps to NYMEX WTI futures vanilla options. We find that price jumps and stochastic volatility are necessary to fit options. Despite the averaging effect, we show that Asian options remain sensitive to jump risk and that ignoring the discontinuities can lead to substantial mispricings.

Book Description
The predominant fear in capital markets is that of a price spike. Commodity markets differ in that there is a fear of both upward and down jumps, this results in implied volatility curves displaying distinct shapes when compared to equity markets. The use of a novel functional data analysis (FDA) approach, provides a framework to produce and interpret functional objects that characterise the underlying dynamics of oil future options. We use the FDA framework to examine implied volatility, jump risk, and pricing dynamics within crude oil markets. Examining a WTI crude oil sample for the 2007-2013 period, which includes the global financial crisis and the Arab Spring, strong evidence is found of converse jump dynamics during periods of demand and supply side weakness. This is used as a basis for an FDA-derived Merton (1976) jump diffusion optimised delta hedging strategy, which exhibits superior portfolio management results over traditional methods.

Book Description
This paper presents a simple macroeconomic model of the oil market. The model incorporates features of oil supply such as depletion, endogenous oil exploration and extraction, as well as features of oil demand such as the secular increase in demand from emerging-market economies, usage efficiency, and endogenous demand responses. The model provides, inter alia, a useful analytical framework to explore the effects of: a change in world GDP growth; a change in the efficiency of oil usage; and a change in the supply of oil. Notwithstanding that shale oil production today is more responsive to prices than conventional oil, our analysis suggests that an era of prolonged low oil prices is likely to be followed by a period where oil prices overshoot their long-term upward trend.

Book Description
The blowout of the Macondo well on April 20, 2010, led to enormous consequences for the individuals involved in the drilling operations, and for their families. Eleven workers on the Deepwater Horizon drilling rig lost their lives and 16 others were seriously injured. There were also enormous consequences for the companies involved in the drilling operations, to the Gulf of Mexico environment, and to the economy of the region and beyond. The flow continued for nearly 3 months before the well could be completely killed, during which time, nearly 5 million barrels of oil spilled into the gulf. Macondo Well-Deepwater Horizon Blowout examines the causes of the blowout and provides a series of recommendations, for both the oil and gas industry and government regulators, intended to reduce the likelihood and impact of any future losses of well control during offshore drilling. According to this report, companies involved in offshore drilling should take a "system safety" approach to anticipating and managing possible dangers at every level of operation-from ensuring the integrity of wells to designing blowout preventers that function under all foreseeable conditions-in order to reduce the risk of another accident as catastrophic as the Deepwater Horizon explosion and oil spill. In addition, an enhanced regulatory approach should combine strong industry safety goals with mandatory oversight at critical points during drilling operations. Macondo Well-Deepwater Horizon Blowout discusses ultimate responsibility and accountability for well integrity and safety of offshore equipment, formal system safety education and training of personnel engaged in offshore drilling, and guidelines that should be established so that well designs incorporate protection against the various credible risks associated with the drilling and abandonment process. This book will be of interest to professionals in the oil and gas industry, government decision makers, environmental advocacy groups, and others who seek an understanding of the processes involved in order to ensure safety in undertakings of this nature.
