The primary purpose of this article is to conduct the Fourier Nonlinear Unit Root Test to check Purchasing Power Parity (PPP) for seven cryptocurrencies traded in seventeen countries from 2010 to 2021. The unit root test provides moderate support to the PPP hypothesis when we use each...

In a recent article, with a strong theoretical argument but poor empiricalsupport, military spending was identified to be a determinant of realexchange rate or a factor causing the PPP to deviate from equilibriumexchange rate. The poor empirical results were mostly due to a small numberof...

Bilateral real exchange rate is used in examining the price of domestic goods in terms of partner's goods and it is especially useful for bilateral modelling. On the other hand, real effective exchange rate serves as the price of domestic goods in terms of a basket of foreign goods and is...

Testing purchasing power parity (PPP) using black market exchange rate data has gained popularity in recent times. It is claimed that black market exchange rate data more often support the PPP than the official exchange rate data. In this study, to assess both the long run stability of exchange...

In theoretical literature, smuggling is considered as a factor contributing to the deviation of the PPP-based exchange rates from the equilibrium exchange rates with little empirical support. In this paper, we used panel data for 33 developing countries over the period 1982-1995 and used panel...
