The objective of this article is to study long-run purchasing power parity (PPP) for a panel of 21 OECD countries from the end of the Bretton Woods era by applying a wide range of the econometric techniques available. This will allow us to present a comprehensive up to date examination of the empirical validity of PPP, covering the weak and strong versions of the hypothesis with individual and panel analysis, including the absence or presence of cross-dependency, the linear or non-linear behaviour of the real exchange rates, and the degree of persistence. Overall, the results provide evidence in favour of PPP.

AbstractThis article examines the impact of opacity in announcing the central bank's inflation target on macroeconomic volatility and welfare, considering the interaction between an independent central bank and a fiscal authority. Our findings suggest that a key factor influencing the effects of central bank transparency is the relative importance placed by the central bank, compared to the government, on output stabilization versus inflation stabilization. Specifically, when output stabilization is relatively more important for the central bank than for the government, full opacity may benefit the central bank, but not necessarily society as a whole.
