This paper attempts to find norms for long-run national price levels,and therefore, by implication, for exchange rates, that are superior to those implied by the absolute or relative versions of purchasing power parity theory. The structural variables we have found to determine these price...

The purpose of this paper is to call attention to the need for a theory of comparative national price levels and to explore some of the elements that seem to belong to such a theory. Most theoretical discussions have maintained that national price levels tend towards equality and focus on...

The real exchange rate (RER) measures relative price levels across countries, capturing deviations from purchasing power parity (PPP). RER is a key variable in international macroeconomic models as it is central to equilibrium conditions in both goods and asset markets. It is also one of the...

The purpose of this paper was to investigate whether there is a relationship between the degree of wage dispersion in a country and its price level relative to other countries, compared in a common currency. It was found that once a country's real per capita income and deviations of its exchange...

This paper examines changes in national price levels and prices of tradables and nontradables and relates them to changes in variables found earlier to be associated with price level differences among countries. Across countries, national price levels increase systematically with the level of a...

We propose a dynamic general equilibrium model of exchange rate determination, which simultaneously accounts for all major puzzles associated with nominal and real exchange rates. This includes the Meese-Rogoff disconnect puzzle, the PPP puzzle, the terms-of-trade puzzle, the Backus- Smith...

Financial markets play two roles with implications for the exchange rate: they accommodate risk sharing and act as a source of shocks. In prevailing theories, these roles are seen as mutually exclusive and individually face challenges in explaining exchange rate dynamics. However, we demonstrate...

We use a general open-economy wedge-accounting framework to characterize the set of shocks that can account for major exchange rate puzzles. Focusing on a near-autarky behavior of the economy, we show analytically that all standard macroeconomic shocks -- including productivity, monetary,...

Inflation has risen sharply in many countries since the COVID-19 outbreak. Economists have debated the underlying causes. In this paper, we examine the drivers of the global import price inflation, which peaked at approximately 11 percent a year. We find that a common global component closely...
