This paper is an econometric investigation of the determinants of the real value of the South African rand over the period 1984-2006. The results show a relatively good fit. As so often with exchange rate equations, there is substantial weight on the lagged exchange rate, which can be attributed...

Fixed and flexible exchange rates each have advantages, and a country has the right to choose the regime suited to its circumstances. Nevertheless, several arguments support the view that the de facto dollar peg may now have outlived its usefulness for China. (1) China's economy is on the...

Vaccination rates have a statistically significant downward effect on the Covid-19 death rate across US counties, as of August 12, 2021. Controlling for poverty rates, age, and temperature lowers the magnitude of the estimate a little. Using the Biden-Trump vote in the 2020 election as an...

any studies have replicated the finding that the forward rate is a biased predictor of the future change in the spot exchange rate. Usually the forward discount actually points in the wrong direction. But virtually all those studies apply to advanced economies and major currencies. We apply the...

The corners hypothesis holds that intermediate exchange rate regimes are vanishing, or should be. Surprisingly for a new conventional wisdom, this hypothesis so far lacks analytic foundations. In part, the generalization is overdone. We nevertheless offer one possible theoretical rationale, a...

We update tests of the credibility of the EMS exchange rate target zones. Our main methodological innovation is to use a survey of exchange rate forecasts, as well as interest differentials, in measuring exchange rate expectations. We investigate the hypothesis -- suggested by the apparent...

We investigate the properties of exchange rate forecasts with a data set encompassing a broad cross section of currencies. The key finding is that expectations appear to be biased in our sample. This result is robust to the possibility of random measurement error in the survey measures....
