Discussion: Commodity Price Discovery: Problems That Have Solutions or Solutions That Are Problems AgEcon
Fortenbery, T. Randall.
This paper examines three invited papers focused on commodity prices. Public responses to high nominal commodity prices and perceived increases in price risk have ranged from attempts to assign blame, attempts to change contracting arrangements, and development of public policy that ‘‘protects’’ the market from future occurrences of unacceptable behavior. Interestingly, a result of increased commodity price volatility has suggested that futures markets no longer ‘‘work.’’ This is ironic given that futures markets initially came into existence as tools for managing the negative impacts of commodity price risk. In response to perceptions of market failure some are looking for strategies to regulate the who and how of futures trading.

Price efficiency and speculative trading in cocoa futures markets AgEcon
Nardella, Michele.
In recent years a number of market participants called into question the efficiency of the price discovery mechanism in commodity futures markets. They believe that speculators move commodity futures markets away from their fundamentals by distorting prices and exacerbating volatility. The smoking gun of these allegations is the empirical observation that speculative buying (selling) precedes movements in the cocoa futures markets. Among soft commodities, the cocoa futures market represents an interesting case study. In the last decades, speculators’ open interest is increased by nearly 4 times, fuelling the apprehension of practitioners and market analysts. This paper evaluates the efficiency of the price discovery mechanism in cocoa futures markets....

Devil or Angel? The Role of Speculation in the Recent Commodity Price Boom (and Bust) AgEcon
Irwin, Scott H.; Sanders, Dwight R.; Merrin, Robert P..
It is commonly asserted that speculative buying by index funds in commodity futures and over–the–counter derivatives markets created a ‘‘bubble’’ in commodity prices, with the result that prices, and crude oil prices, in particular, far exceeded fundamental values at the peak. The purpose of this paper is to show that the bubble argument simply does not withstand close scrutiny. Four main points are explored. First, the arguments of bubble proponents are conceptually flawed and reflect fundamental and basic misunderstandings of how commodity futures markets actually work. Second, a number of facts about the situation in commodity markets are inconsistent with the existence of a substantial bubble in commodity prices. Third, available statistical evidence...

The Performance of Chicago Board of Trade Corn, Soybean, and Wheat Futures Contracts after Recent Changes in Speculative Limits AgEcon
Irwin, Scott H.; Garcia, Philip; Good, Darrel L..
Three attributes of futures contract behavior important for market performance—liquidity, volatility, and convergence—are investigated before and after the 2005 increase in speculative position limits for corn, soybean, and wheat contracts at the Chicago Board of Trade. The analysis of liquidity and market depth reveals a sharp increase in open interest for corn, soybeans and wheat beginning in late 2005. The increase in position limits likely accommodated the increase in speculative interest in corn, soybean and wheat futures, but some of the increase would have occurred without the increase as new market participants received hedge exemptions. The analysis of price volatility revealed no large change in measures of volatility after the change in...

Global Food Price Volatility and Spikes: An Overview of Costs, Causes, and Solutions AgEcon
von Braun, Joachim; Tadesse, Getaw.
Since the 2007–08 food crisis, many thoughtful analyses have addressed the causes and impacts of high and volatile international food prices and proposed solutions to the crisis. These studies have covered global as well as local food price dynamics and policy reactions. The food price problem is, however, far-reaching, and its impacts are wide and interrelated. The price formation mechanism has become highly complex and dynamic. Policy actions are politically and economically sensitive. This situation calls for continuous and comprehensive assessments of the problem to provide timely and evidence-based knowledge for policy makers. This paper reviews existing evidence and theories and presents new thoughts and insights from analyses to enlighten the course...

Testing for Speculative Behavior in US Corn Ethanol Investments AgEcon
Kumarappan, Subbu; Gustafson, Cole R..
Crude oil price speculation during 2000s could have increased installed capacity in corn ethanol plants beyond what was warranted by the market factors. We use Muth’s commodity pricing model and Flood and Garber’s tests to test for speculative investment in US corn ethanol industry. The ethanol price expectations are derived using a system of supply-demand-inventory describing US ethanol markets under rational expectations (perfect foresight). These price expectations can help differentiate the installed capacity into two: capacity supported by the market fundamentals and the probable capacity that is installed based on speculation. Econometric estimation procedures and functional form approximations are discussed.

Stock Prices in a Speculative Market: The Chinese Split-Share Reform AgEcon
Beltratti, Andrea; Caccavaio, Marianna; Bortolotti, Bernardo.
In 2005-2006 China reformed its stock market by eliminating non-tradable shares. The regulator set general guidelines and then assigned responsibility for implementation to each company. We derive relations that should have been followed by the prices of stocks and exploit a company-level data set to compare the actual and the theoretical price reactions. We find evidence for abnormal returns both before the beginning of the reform and during the reform. Cross-sectionally, abnormal returns are associated mainly with turnover and compensation. This shows that in a speculative market, investors do not properly react to unambiguous corporate actions.

Milk Price Volatility and its Determinants AgEcon
Dong, Fengxia; Du, Xiaodong; Gould, Brian W..
The classified pricing of fluid milk under the Federal Milk Marketing Orders (FMMO) system combined with the cash settlement feature of Class IIII milk futures contracts generate a unique volatility pattern of these futures markets in the sense that the volatility gradually decreases as the USDA price announcement dates approaching in the month. Focusing on the evolution of volatility in Class III milk futures market, this study quantifies the relative importance of a set of factors driving milk price variation. While volatilities in both corn futures market and financial market Granger-cause the milk price volatility, the impact of financial market is more persistent. Besides embedded seasonality, market demand and supply conditions in the dairy...
