We use daily data on bank reserves and overnight interest rates to document a striking pattern in the high-frequency behavior of the U.S. market for federal funds: depository institutions tend to hold more reserves during the last few days of each “reserve maintenance period,” when the...

We analyze the performance of kernel density methods applied to grouped data to estimate poverty (as applied in Sala-i-Martin, 2006, QJE). Using Monte Carlo simulations and household surveys, we find that the technique gives rise to biases in poverty estimates, the sign and magnitude of which...

Consensus estimates put the half-life of deviations from purchasing power parity (PPP) at about four years (Rogoff, 1996). However, conventional least squares estimates of half-lives are biased downward. Accordingly, as a preferred measure of the persistence of real exchange rate shocks, this...

“Program numbers” from a sample of IMF-supported programs are studied as if they were forecasts, through statistical analyses of the relationship between projections and outcomes for growth, inflation, and three balance of payments concepts. Statistical bias is found only for projections of...

After a short-lived slowdown in the immediate aftermath of the global financial crisis and a swift rebound, emerging markets (EM) are now entering a period of slower growth. In fact, growth is now lower than the post-crisis peak of 2010-11, as well as the rates seen in the decade before the...

This Selected Issues paper attempts to analyze the end-point problem and improve the quality of potential GDP estimates for Germany. It projects that Germany’s potential GDP growth will slow over the coming decade, mainly because of declining labor input. The paper focuses on a long-term...
