We find an example where real exchange rate (RER) is stationary and the nominal exchange rate and the price levels are cointegrated but purchasing power parity (PPP) does not hold, which reveals a fault of the unit root and cointegration tests in this use. We argue that the distribution of an...

In the current paper, a new and simple currency valuation model called the ratio model is proposed based on the Penn effect (a systematic deviation of the purchasing power parity (PPP)). The ratio model, which reduces the uncertainty of the econometric specification that many other valuation...

A simple currency valuation model is given. The model is based on the Penn effect but reduces the uncertainty of the econometric specification that the Penn effect and many other models have. We use the model to valuate eleven main currencies’ bilateral real exchange rate against the US dollar...

The behavioral equilibrium exchange rate (BEER) and the Penn effect models are compared via their applications on the valuation of the Renminbi (RMB). The definition for the Penn effect model is provided. The differences and relations between the two models in various econometric method settings...

The value of China's currency, the renminbi (RMB), and the conduct of China's exchange rate policy have generated intense debate in academic and international policy circles. Despite the accumulation of empirical evidence regarding the degree of RMB misalignment over the past few years, the...

We evaluate whether the Renminbi (RMB) is misaligned, relying upon conventional statistical methods of inference. A framework built around the relationship between relative price and relative output levels is used. We find that, once sampling uncertainty and serial correlation are accounted for,...
