Does Purchasing Power Parity Hold Sometimes? Regime Switching in Real Exchange Rates [PDF]

, 2007
Real exchange rates are quite persistent. Standard unit root tests are not very powerful in drawing a conclusion regarding the validity of purchasing power parity [PPP].

Purchasing Power Parity and Country Characteristics: Evidence from Time Series Analysis [PDF]

This paper investigates the relationships between country characteristics and the validity of PPP. We use three alternative time series methods to test for the stationarity of real exchange rates for each of the 72 countries over the period from 1976 to ...

A new analysis of the determinants of the real dollar-sterling exchange rate: 1871-1994 [PDF]

Nonlinear models of deviations from PPP have recently provided an important, theoretically well motivated, contribution to the PPP puzzle. In recent work the equilibrium level has been modelled either as constant or as time varying with very similar ...

PPP Strikes Back: Aggregation and the Real Exchange Rate [PDF]

We show the importance of a dynamic aggregation bias in accounting for the PPP puzzle. We prove that established time series and panel methods substantially exaggerate the persistence of real exchange rates because of heterogeneity in the dynamics of ...

A Smart Realtime Service to Broadcast the Precise Orbits of GPS Satellite and Its Performance on Precise Point Positioning

Sensors, 2020
At present, Global Position System (GPS) navigation ephemeris mainly broadcasts satellite orbits with meter-level precision for standard point positioning and precise relative positioning. With the rapid development of real-time precise point positioning

Are PPP Tests Erratically Behaved? Some Panel Evidence [PDF]

This paper examines whether, in addition to standard unit root and cointegration tests, panel approaches also produce test statistics behaving erratically when applied to tests for PPP.

The Sri Lankan Rupee and Purchasing Power Parity during the Current Floating Period [PDF]

This paper examines the empirical validity of purchasing power parity (PPP) hypothesis in a Sri Lankan context using exchange rates for six foreign currencies during the period January 1986 to November 2000.
