national currency depreciation or appreciation has always been argued seriously among policymakers since changing in exchange rate could cause improvement or deficit in trade balance. these changes affect the trade volume of a country in both short-run and long-run. long-run effects are recognized as the marshall-lerner condition, while short-run effects are analyzed by two concepts: j-curve an...

Theory tells us that output, the capital stock and the user cost of capital are cointegrated. From the capital accumulation identity, it also follows that the capital stock and investment have a long-run proportional relationship. This has been used to justify the estimation of investment equations embodying a long-run relation between investment and output, rather than between the capital stoc...

We model and analyze strategic interaction over time in a duopoly. Each period the …rms independently and simultaneously take two sequential decisions. First, they decide whether or not to advertise, then they set prices for goods which are imperfect substitutes. Not only the own, but also the other …rm’s past advertisement e¤orts a¤ect the current ‘sales potential’ of each …rm. How much of thi...

This paper uses recent developments in measuring correlation to examine the relationship between inflation and relative price variability. The results suggest that the positive correlation holds not only in the short-run but also in the long-run. This finding has important implications for theoretical models that purport to explain this relationship: such models must incorporate features that g...
