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,...

The general price level does not provide a sensitive indicator of whether monetary policy is tight or loose, because mostprices are sticky. Interest rates are free to move, but they are an ambiguous indicator of monetary policy: one does not know whether changes in the interest rate are due to...

Countries that specialize in commodity exports often exhibit a correlation between the relevant commodity price and the value of their currency. We explore a natural but little-studied explanation for this correlation. An increase in the commodity price leads to increases in the future values of...

We examine the channels through which commodity price super-cycles affect the economy. Exploiting regional variation in exposure to commodity price shocks and administrative firm-level data from Brazil we disentangle two transmission channels. Higher commodity prices increase domestic demand...

Emerging economies, particularly those dependent on commodity exports, are prone to highly disruptive economic cycles. This paper proposes a small open economy model for a net commodity exporter to quantitatively study the triggers of these cycles. The economy consists of two sectors, one of...

It is striking how often countries with oil or other natural resource wealth have failed to grow more rapidly than those without. This is the phenomenon known as the Natural Resource Curse. The principle has been borne out in some econometric tests of the determinants of economic performance...

In this paper we seek to produce forecasts of commodity price movements that can systematically improve on naive statistical benchmarks, and revisit the forecasting performance of changes in commodity currencies as efficient predictors of commodity prices, a view emphasized in the recent...

The national terms of trade, defined as the ratio of an export price index to an import price index has been extensively studied empirically. In this paper we construct an alternative measure, which we call the consumption terms of trade. This measure recognizes the fact that consumers and firms...

Poor countries are more volatile than rich countries, and we know this volatility impedes their growth. We also know that commodity price volatility is a key source of those shocks. This paper explores commodity and manufactures price over the past three centuries to answer three questions: Has...

We study the correlation between a belief concerning individualism and a measure of luck in the US during the period 1983-2004. The measure of beliefs is the answer to a question related to whether the poor should be helped by the government or if they should help themselves, while the measure...
