COMMODITY PRICE AND INFLATION DYNAMICS: EVIDENCE FROM BRIICS

Volatility and Commodity Price Dynamics

Commodity prices tend to be volatile, and volatility itself varies over time. Changes in volatility can affect market variables by directly affecting the marginal value of storage, and by affecting a component of the total marginal cost of production: the opportunity cost of exercising the option to produce the commodity now rather than waiting for more price information. I examine the role of ...

Inflation And Relative Price Dispersion: Evidence For Iran

Competitive Storage and Commodity Price Dynamics

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...

Price Setting during Low and High Inflation: Evidence from Mexico

This paper provides new insight into the relationship between inflation and consumer price setting by examining a large data set of Mexican consumer prices covering episodes of both low and high inflation, as well as the transition between the two. Overall, the economy shares several characteristics with time-dependent models when the annual inflation rate is low (below 10-15%), while displayin...

Price dispersion and inflation rates: evidence from scanner data

In this paper we investigate the relationship between price dispersion and inflation; we use weekly retail scanner data from 2009 to 2011 to measure price dispersion and inflation for several dairy products. We implement a linear model to investigate the linkage between price dispersion and consumer price indexes. As in the previous literature, we obtain mixed results with respect to the relati...
