Using a difference-in-differences estimation framework and state-level data, we investigate the potential role of HIV/AIDS in contributing to declining abortion utilization in the United States. Our results suggest that the perceived risk of HIV contraction negatively affected unwanted...

Measuring deviations from purchasing power parity has been the subject of extensive investigation. The most common practice in empirical research for measuring real exchange rate persistence is to estimate univariate autoregressive (AR) time series models and calculate the half-life, defined as...

Using median-unbiased estimation based on Augmented Dickey--Fuller (ADF) regressions, recent research has questioned the validity of Rogoff's ‘remarkable consensus’ of 3--5 year half-lives of deviations from Purchasing Power Parity (PPP). The confidence intervals of these half-life...
