The present paper develops Adaptive Trees, a new machine learning approach specifically designed for economic forecasting. Economic forecasting is made difficult by economic complexity, which implies non-linearities (multiple interactions and discontinuities) and unknown structural changes (the...

International quality measurement work is moving beyond the consideration of health system or national level variations to understand variations within countries and enable more meaningful cross-country comparison. Hospital performance is one key area where policy makers are increasing their...

The forecasting uncertainty around point macroeconomic forecasts is usually measured by the historical performance of the forecasting model, using measures such as root mean squared forecasting errors (RMSE). This measure, however, has the major drawback that it is constant over time and hence...

This paper examines the relationship between trade liberalisation and migration in the case of Mexico. The increasing bilateral trade between Mexico and the United States after signing the North American Free Trade Agreement (NAFTA) was supposed to stem the illegal Mexican migration flow by...

Inflation has become much less sensitive to movements in unemployment in recent decades. A common explanation for this change is that inflation expectations have become better anchored as a consequence of credible inflation targeting by central banks. In order to evaluate this hypothesis, the...

The Great Recession and the subsequent period of subdued GDP growth in most advanced economies have highlighted the need for macroeconomic forecasters to account for sudden and deep recessions, periods of higher macroeconomic volatility, and fluctuations in trend GDP growth. In this paper, we...

This paper contributes to the empirical literature investigating reasons for the fall in real interest rates in advanced economies. It focuses on selected drivers from three broad categories: demographic changes; imbalances between supply of and demand for safe assets; and monetary policy at...

This paper explores the relationship between policy settings and extreme positive and negative growth events, what we call GDP tail risks, using quantile regression methods. Conditioning on several country characteristics such as the size, stage of development and openness to trade as well as...

A statistically significant relationship between the unemployment gap and inflation can be found for a clear majority of OECD countries, but the magnitude of the effect is typically weak. A corollary is that the effect of labour market slack on inflation can often be dominated by other shocks,...
