In the first chapter (The Wealth Effects of Government Investment in Publicly Traded Firms), I study how government share ownership affects shareholder wealth. I find that government investments with higher likelihood of political interference have a negative influence on shareholder wealth, while the opposite is true for government investments with economic objectives. In the second chapter (Government Ownership and the Cost of Debt: Evidence form Government Investment in Publicly Traded Firms), I investigate how government share ownership affects the cost of debt of publicly traded firms. I find that government ownership generally leads to a higher cost of debt, except for times of economic and firm distress, when the value of the implicit government guarantee is associated with a reduction in the cost of debt. In the third chapter (Financial Trading, Spot Oil Prices, and Inventory: Evidence from the U.S. Crude Oil Market), I confirm the existence of an active cash and carry market in crude oil in Cushing, OK, the main U.S. crude oil futures settlement location. In other words, crude oil inventories in Cushing, but not in any other U.S. crude oil storage locations, are explained by the spread between the financial and the physical price of oil in addition to operational factors.227 pagesapplication.pdfInvestment of public fundsStockholder wealthCorporate debtInterest ratesPetroleum industry and trade--Oklahoma--CushingPetroleum industry and trade--Oklahoma--Cushing--InventoriesCommodity futures--Oklahoma--Cushingtext
