The positive correlation between real (PPP) investment rates and levels of PPP income across countries is one of the most robust findings of the empirical growth literature. We show that this relationship is almost entirely driven by differences in the price of investment relative to output, rather than by differences in nominal investment rates. When measured in nominal terms (i.e., at nationa...

The purchasing power parity puzzle relates to the adjustment of real exchange rates. Real exchange rates are extremely volatile, suggesting that temporary shocks emanate from the monetary sector. But the half-life of real exchange rate deviations is extremely large – 2.5 to 5 years. This halflife seems too large to be explained by the slow adjustment of nominal prices. We offer a different inte...

The present paper analyzes propagation of shocks to food and energy prices in 46 countries with data from the period 1999-2010. The empirical evidence suggests that in only one of the countries considered, a shock to the price of either energy or food shows no propagation to the prices of the goods and services included in the core inflation measure. In general, the propagation effect of food p...

â â â  â â â  abstract â  using a structural var with block exogeneity, diagonality and identifying restrictions, this paper analyzes: first, the macroeconomic linkages among the oil price, u.s. output, interest rate, money supply, general price level and exchange rate and second, the relationships of the macroeconomic variables with the price indices of ten international nonfuel commodity grou...

By disaggregating price indices, it becomes apparent that the real exchange rate consists of the real exchange rate for a single good and a weighted sum of relative prices between goods. When applying a battery of panel unit root tests to this sum and its components, it is found that both the sum and the relative prices are non-stationary. This implies that PPP is invalid even if the LOP holds ...

this study examined the effects of trade liberalization and exchange rate changes on carbohydrate staples in nigeria. secondary data published from 1974 to 2006 on cassava exports and rice imports as well as non-tradable carbohydrate staples were used. it was hypothesized that exchange rate changes and trade liberalization via price relatives, trade intensity and nominal protection coefficient ...

One of the main issues in international finance is the ratio of exchange rate pass through to consumer prices.

In the present study, the effects of positive and negative impacts of the exchange rate on inflation rate and other macroeconomic variables of I...
