Available in PDF, EPUB and Kindle. Book excerpt: This paper provides a comprehensive analysis of the degree of co-movement among the nominal price returns of 11 major energy, agricultural and food commodities based on monthly data between 1970 and 2013. A uniform-spacings testing approach, a multivariate dynamic conditional correlation model and a rolling regression procedure are used to study the extent and the time-evolution of unconditional and conditional correlations. The results indicate that (i) the price returns of energy and agricultural commodities are highly correlated; (ii) the overall level of co-movement among commodities increased in recent years, especially between energy and agricultural commodities and in particular in the cases of maize and soybean oil, which are important inputs in the production of biofuels; and (iii) particularly after 2007, stock market volatility is positively associated with the co-movement of price returns across markets.

Book Synopsis The Comovement in Commodity Prices by : Mr.Ron Alquist
Download or read book The Comovement in Commodity Prices written by Mr.Ron Alquist and published by International Monetary Fund. This book was released on 2013-06-05 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present a simple macroeconomic model with a continuum of primary commodities used in the production of the final good, such that the real prices of commodities have a factor structure. One factor captures the combined contribution of all aggregate shocks which have no direct effects on commodity markets other than through general equilibrium effects on output, while other factors represent direct commodity shocks. Thus, the factor structure provides a decomposition of underlying structural shocks. The theory also provides guidance on how empirical factors can be rotated to identify the structural factors. We apply factor analysis and the identification conditions implied by the model to a cross-section of real non-energy commodity prices. The theoretical restrictions implied by the model are consistent with the data and thus yield a structural interpretation of the common factors in commodity prices. The analysis suggests that commodity-related shocks have generally played a limited role in global business cycle fluctuations.
Book Synopsis The Influence of Commodity Speculation on Commodity Price Development by : Nicolas Schreiber

This book was released on 2016-07-15 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bachelorarbeit aus dem Jahr 2014 im Fachbereich BWL - Bank, Börse, Versicherung, Johann Wolfgang Goethe-Universität Frankfurt am Main, Sprache: Deutsch, Abstract: Commodity prices have been rising significantly since the early 2000s with price growth reaching its fastest pace between 2006 and 2008. While nearly all commodities were hit by the aforementioned price spikes, price spikes where particularly pronounced for mineral commodities. For the most part of recent research two different approaches are applied to measure the impact of speculation on price development. The first one examines if there is any change in commodity price development due to the aforementioned increased financialization of commodity markets, whereas the second one compares the behavior of commodity prices with and without an existing futures market. This thesis combines both approaches and tests the hypotheses that either the first-time introduction of derivatives or the introductions of regulatory governmental acts that facilitate speculative index investment in commodities have significant effects on commodity price development by the example of copper traded on US-based exchanges. For this purpose, relevant copper price characteristics will be analyzed before and after possibly speculation-conducive events (i.e. the introduction of copper futures trading and two selected acts) for the period from 1971 to 2010. Furthermore, following Tang and Xiong (2012), this thesis examines if the introduction of governmental acts of the aforementioned type induces an increased market integration of non-energy commodity markets. This is of particular interest as market integration can at times induce increased volatility spillovers between the respective markets (Tang & Xiong, 2012). The first part of this work gives a short overview of the technical background necessary to understand the relationship between commodity prices and speculation. The second part provides a general review of related literature and research on the relationship between commodity prices and speculation. The third part focuses on the methodology of the empirical analysis. The fourth part of this work presents the results and is followed by the conclusion in part five.
Book Synopsis Commodity Returns Co-Movements by : Charlot Philippe
Download or read book Commodity Returns Co-Movements written by Charlot Philippe and published by . This book was released on 2015 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper investigates dynamic correlations both across commodities and between commodities and traditional assets, such as equities and government bonds, using the Regime Switching Dynamic Correlation (RSDC) model. There are three major findings. First, results from correlations both across commodities and between them and equities and bonds are in line with the “style” effect theoretical findings. Before the recent financial crisis, while correlations across In-index commodities started to increase from mid-2005, correlations between them and equities and bonds remained at low level. Second, all correlations increased markedly with a regime change which coincides exactly with the demise of Lehman Brothers on September 15, 2008. We therefore suggest that the low correlation between In-index commodities and equities and bonds detected before the financial crisis should not be interpreted as a weak integration between commodity and financial markets. Integration was actually high, as revealed by the financial crisis, but was masked by the “style” effect. Finally, the new and original finding here is the temporary nature detected of the financial crisis effect on correlations which reverted to their pre-crisis level from April 2013. This highlights the impact of the financial-based factors on commodity price movements.

Book Synopsis The Myth of Comoving Commodity Prices by : Mr.Paul Cashin
Download or read book The Myth of Comoving Commodity Prices written by Mr.Paul Cashin and published by International Monetary Fund. This book was released on 1999-12-01 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a common perception that the prices of unrelated commodities move together. This paper re-examines this notion, using a measure of comovement of economic time series called concordance. Concordance measures the proportion of time that the prices of two commodities are concurrently in the same boom period or same slump period. Using data on the prices of several unrelated commodities, the paper finds no evidence of comovement in commodity prices. The results carry an important policy implication, as the study provides no support for earlier claims of irrational trading behavior by participants in world commodity markets.
Book Synopsis Increasing Trends in the Excess Comovement of Commodity Prices by : Kazuhiko Ohashi
Download or read book Increasing Trends in the Excess Comovement of Commodity Prices written by Kazuhiko Ohashi and published by . This book was released on 2016 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: We investigate how the excess comovement of commodity prices, that is, the correlation in commodity returns after filtering out common fundamental shocks, has changed over the past three decades by developing the smooth-transition dynamic conditional correlation model that can capture long-run trends and short-run dynamics of correlation simultaneously. Using data from 1983 to 2011, we find that significant increasing long-run trends in excess comovement have appeared since around 2000. We confirm that these increasing trends are neither an artefact of the financial crisis after the bankruptcy of Lehman Brothers in September 2008 nor the time-varying sensitivities of commodity returns to common fundamental shocks. Moreover, we find that no significant increasing trends exist in the excess comovement among off-index commodities and that the surge of global demand alone cannot explain the increasing trends. These findings provide additional evidence for the timing and scope of the recent increasing commodity-return correlations that suggest the influence of the financialization of commodity markets starting around 2000.
Book Synopsis The Excess Co-movement of Commodity Prices by : Robert S. Pindyck
Download or read book The Excess Co-movement of Commodity Prices written by Robert S. Pindyck and published by . This book was released on 1988 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper tests and confirms the existence of a puzzling phenomenon - the prices of largely unrelated raw commodities have a persistent tendency to move together. We show that this comovement of prices is well in excess of anything that can be explained by the common effects of past, current, or expected future values of macroeconomic variables such as inflation, industrial production, interest rates, and exchange rates. These results are a rejection of the standard competitive model of commodity price formation with storage.
Book Synopsis Commodity Price Dynamics by : Craig Pirrong
Download or read book Commodity Price Dynamics written by Craig Pirrong and published by Cambridge University Press. This book was released on 2011-10-31 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Three Essays In Commodity Price Dynamics by : Amal Dabbous
Download or read book Three Essays In Commodity Price Dynamics written by Amal Dabbous and published by . This book was released on 2015 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis consists of three essays in commodity price dynamics. In the first essay, we embed a staggered price feature into the speculative storage model of Deaton and Laroque (1996). Intermediate goods inventory speculators are added as an additional source of intertemporal linkage which helps us to replicate the stylized facts of the observed commodity price dynamics. The staggered pricing mechanism adopted in this paper can be viewed as a parsimonious way of approximating various types of frictions that increase the degree of persistence in the first two conditional moments of commodity prices. The structural parameters of our model are estimated by simulated method of moments using actual prices for four agricultural commodities. Simulated data are then employed to assess the effects of our staggered price approach on the time series properties of commodity prices. Our results lend empirical support to the possibility of staggered prices. The second essay investigates the determinants of the percentage change in commodity prices. We apply the dynamic Gordon growth model technique and conduct the variance decomposition for the percentage change in spot commodity prices to 6 agricultural commodities. The model explains the percentage change in spot commodity prices in terms of the expected present discounted values of interest rate, yield spread, open interest and convenience yield. Empirical results indicate that the model is successful in capturing a large proportion of the variability in the 6 agricultural commodity prices. Moreover, we show that yield spread and open interest help predicting changes in commodity prices. Finally, the third essay evaluates different hedging strategies for eleven commodities. In addition to the traditional regression hedge ratio model (OLS) and the vector error correction model (VECM), we estimate dynamic hedge ratios using the conventional dynamic conditional correlation model (DCC) of Engle (2002) and the diagonal BEKK model (DBEKK) of Engle and Kroner (1995). Moreover, we propose two more advanced models, the DCC model and the DBEKK model that will account for the impact of the growth rate of open interest on market’s volatility and co-movements of commodity spot and futures returns. The empirical analysis shows that adding the growth rate of open interest improves the in-sample hedging effectiveness of the DCC model. Furthermore, the out-of-sample hedging exercise empirical results show that static models present the best out-of-sample hedging performance for 5 of the commodities. The DCC model presents the smallest basis variance for 4 of the commodities. The DBEKK model with the growth rate of open interest performs the best in terms of the basis variance reduction for corn and wheat. Our out-of-sample empirical findings provide important implications for futures hedging and highlight the fact that the use of static models to determine the optimal hedge ratio could be more effective than the use of dynamic hedge ratio models.
Book Synopsis Bayesian Multivariate Time Series Methods for Empirical Macroeconomics by : Gary Koop
Download or read book Bayesian Multivariate Time Series Methods for Empirical Macroeconomics written by Gary Koop and published by Now Publishers Inc. This book was released on 2010 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bayesian Multivariate Time Series Methods for Empirical Macroeconomics provides a survey of the Bayesian methods used in modern empirical macroeconomics. These models have been developed to address the fact that most questions of interest to empirical macroeconomists involve several variables and must be addressed using multivariate time series methods. Many different multivariate time series models have been used in macroeconomics, but Vector Autoregressive (VAR) models have been among the most popular. Bayesian Multivariate Time Series Methods for Empirical Macroeconomics reviews and extends the Bayesian literature on VARs, TVP-VARs and TVP-FAVARs with a focus on the practitioner. The authors go beyond simply defining each model, but specify how to use them in practice, discuss the advantages and disadvantages of each and offer tips on when and why each model can be used.
Book Synopsis Geopolitical Risk on Stock Returns: Evidence from Inter-Korea Geopolitics by : Seungho Jung
Download or read book Geopolitical Risk on Stock Returns: Evidence from Inter-Korea Geopolitics written by Seungho Jung and published by International Monetary Fund. This book was released on 2021-10-22 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: We investigate how corporate stock returns respond to geopolitical risk in the case of South Korea, which has experienced large and unpredictable geopolitical swings that originate from North Korea. To do so, a monthly index of geopolitical risk from North Korea (the GPRNK index) is constructed using automated keyword searches in South Korean media. The GPRNK index, designed to capture both upside and downside risk, corroborates that geopolitical risk sharply increases with the occurrence of nuclear tests, missile launches, or military confrontations, and decreases significantly around the times of summit meetings or multilateral talks. Using firm-level data, we find that heightened geopolitical risk reduces stock returns, and that the reductions in stock returns are greater especially for large firms, firms with a higher share of domestic investors, and for firms with a higher ratio of fixed assets to total assets. These results suggest that international portfolio diversification and investment irreversibility are important channels through which geopolitical risk affects stock returns.
