Intra-national, intra-continental, and intra-planetary PPP
This paper presents a general framework to address several issues that have arisen in recent work that investigates purchasing power parity (PPP) and other inter-regional relative price movements: (1) How can we model real exchange rate movements in a consistent manner, so that our model for the real exchange rate for country B relative to country C is commensurate with our models for country A/ country B and country A/ country C real exchange rates? For example, can things be modeled so that our tests do not depend on the "base country"? (2) How should we handle correlation across real ...
Purchasing power parity and uncovered interest rate parity: the United States 1974-1990
This paper examines the factors behind long-run movements of the dollar. Most recent work has concluded that structural exchange rate models explain only a small proportion of exchange rate movements. However, many economists still find the theory that links exchange rates and interest rates persuasive. We investigate the relationship between exchange rates, prices, and interest rates using multivariate maximum likelihood cointegration tests. In particular, we explicitly test for purchasing power parity and uncovered interest rate parity when using nominal exchange rates, and implicitly test ...
Is purchasing power parity a useful guide to the dollar?
Purchasing power parity within the United States
Economics has many articles of faith. One of the most dearly held is Purchasing Power Parity, which posits that the price of the same good in different regions should be equivalent when no barriers to arbitrage exist. Because Purchasing Power Parity (PPP) is an important assumption in much of international economic theory, this article examines empirical evidence testing this proposition. ; Instead of analyzing international data, this study analyzes PPP between regions of the United States. By comparing regions within a country, it eliminates many of the hypotheses offered to explain the ...
Falling off the fiscal cliff
Some suggest the best alternative strategy may be to combine short-term spending with longer-term fiscal consolidation?though such a strategy may be easier said than done.
