Abstract

This dissertation focuses on forecasting rare macroeconomic events, such as GDP declines and currency crises, using non-parametric methods, highlighting the advantages of the Receiver Operating Characteristic (ROC) curves analysis and the value of qualitative information from expert surveys and textual analysis in macroeconomic forecasting. Chapter 1 shows that the qualitative WES survey can produce accurate directional macroeconomic forecasts for the USA by combining the ROC curves analysis with contingency tables, and that the ROC-optimal thresholds yield more accurate predictions than the alternatives in Hutson et al. (2014). Chapter 2 re-examines indicators of currency crises from Kaminsky and Reinhart (1999) and subsequent studies using the ROC curves analysis and shows that the ROC-optimal thresholds issue more accurate signals than the minimum noise-to-signal ratio previously used in the literature. Modified ROC curves display the relationship between the precision of sent signals and the recall of crisis episodes. Forecast combinations using several ad-hoc rules help to improve forecast accuracy. Chapter 3 highlights asymmetric information about the U.S. economy between the Federal Reserve System (FRS) and the Survey of Professional Forecasters (SPF) via textual analysis of the Federal Open Market Committee (FOMC) minutes. It shows that the SPF forecasters pay close attention to the FOMC minutes available to them at the time of the forecast deadline and efficiently use its information in their set. Yet, they could improve their forecasts should the FOMC minutes from the first quarterly meetings become available without a three-week publication lag. However, during their second quarterly meetings, the FOMC policy-makers accounted only for their own earlier assessment of the U.S. macroeconomy – they did not put weight on the SPF forecasts released a few weeks earlier in the same quarter.
