We consider an economy in which a set of agents own productive assets which provide a commodity dividend stream, and the agents also receive individual commodity income streams over a finite time horizon. The agents can buy and sell this commodity at a certain spot price and buy and sell their shares of the productive assets. The proceeds can be invested in financial assets whose prices are mod...

In recent years, China's commodity housing prices is soaring highly, especially in large cities such as Shanghai. To research the factors affecting Shanghai housing prices, screening variables by the supply and demand perspective, making the variable linear regression by gradually removing the variable method, the results showed that: In the Shanghai-specific context, lending rates and GDP impa...

The paper summarizes key findings of alternative lines of research on the relationship between food and fuel markets, and identifies gaps between two bodies of literature: one that investigates the relationship between food and fuel prices, and another that investigates the impact of the introduction of biofuels on commodity-food prices. The former body of literature suggests that biofuel price...

Assumption of exchange rate overshooting has significant position in international macroeconomic discussion. This phenomenon is one of the abnormal behaviors of exchange rate that happen in short run. Dornbusch (1976) shows that because speed of equilibrium prices is slow relative to asset markets and commodity prices are sticky in the short run, However, over time, commodity prices will rise a...

Many studies conclude that the rise in global food prices due to higher demand from the development of biofuels, climate anomalies, and increased of oil prices. Not only the food commodity index rose more than 60 percent, nonfood commodity price index also rose over 60 percent and crude oil price index has increased even further above 60 percent. The purpose of this study is to analyze the impa...

Global climate anomalies affect world economies and primary commodity prices. One of the more pronounced climate anomalies is El Niño Southern Oscillation (ENSO). In this study I examine the relationship between ENSO and world commodity prices using monthly time series of the sea-surface temperature anomalies in the Nino 3.4 region, and real prices of thirty primary agricultural commodities. I ...

A computational model of a simple commodity economy is examined and a theory of the relationship between commodity values, market prices and the efficient division of social labour is developed. The main conclusions are: (i) the labour value of a commodity is an attractor for its market price; (ii) market prices are error signals that function to allocate the available social labour between sec...

The link (or lack of link) between food commodity prices and consumer prices is an important issue not only for academics but also for policymakers. This paper asks how and to what extent changes in food commodity prices spill over to consumer prices, using a new data set for the euro area as well as a new empirical approach. The authors find that there is a statistically significant link betwe...

Using a sample of commodity spot price indexes over the period 1947-2010, we examine predictability of commodity returns at the monthly, quarterly, and annual horizons. We establish out-of-sample predictability by means of variables such as bond spreads, growth in money supply and industrial production. Predictability is strongest for raw industrials and metals indexes and weakest for foods and...

By buying cheap and selling dear, risk-neutral commodity speculators can smooth commodity prices and induce serial dependence in price even when none would exist under a simple process of supply and demand. Commodity prices are variable and strongly positively correlated from one year to the next. The variability is often explained by supply factors, and the autocorrelation by the activities of...
