Book Synopsis An Algorithmic Crystal Ball: Forecasts-based on Machine Learning by : Jin-Kyu Jung
Download or read book An Algorithmic Crystal Ball: Forecasts-based on Machine Learning written by Jin-Kyu Jung and published by International Monetary Fund. This book was released on 2018-11-01 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forecasting macroeconomic variables is key to developing a view on a country's economic outlook. Most traditional forecasting models rely on fitting data to a pre-specified relationship between input and output variables, thereby assuming a specific functional and stochastic process underlying that process. We pursue a new approach to forecasting by employing a number of machine learning algorithms, a method that is data driven, and imposing limited restrictions on the nature of the true relationship between input and output variables. We apply the Elastic Net, SuperLearner, and Recurring Neural Network algorithms on macro data of seven, broadly representative, advanced and emerging economies and find that these algorithms can outperform traditional statistical models, thereby offering a relevant addition to the field of economic forecasting.
Book Synopsis Deus ex Machina? A Framework for Macro Forecasting with Machine Learning by : Marijn A. Bolhuis
Download or read book Deus ex Machina? A Framework for Macro Forecasting with Machine Learning written by Marijn A. Bolhuis and published by International Monetary Fund. This book was released on 2020-02-28 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: We develop a framework to nowcast (and forecast) economic variables with machine learning techniques. We explain how machine learning methods can address common shortcomings of traditional OLS-based models and use several machine learning models to predict real output growth with lower forecast errors than traditional models. By combining multiple machine learning models into ensembles, we lower forecast errors even further. We also identify measures of variable importance to help improve the transparency of machine learning-based forecasts. Applying the framework to Turkey reduces forecast errors by at least 30 percent relative to traditional models. The framework also better predicts economic volatility, suggesting that machine learning techniques could be an important part of the macro forecasting toolkit of many countries.
Book Synopsis Overfitting in Judgment-based Economic Forecasts: The Case of IMF Growth Projections by : Klaus-Peter Hellwig
Download or read book Overfitting in Judgment-based Economic Forecasts: The Case of IMF Growth Projections written by Klaus-Peter Hellwig and published by International Monetary Fund. This book was released on 2018-12-07 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: I regress real GDP growth rates on the IMF’s growth forecasts and find that IMF forecasts behave similarly to those generated by overfitted models, placing too much weight on observable predictors and underestimating the forces of mean reversion. I identify several such variables that explain forecasts well but are not predictors of actual growth. I show that, at long horizons, IMF forecasts are little better than a forecasting rule that uses no information other than the historical global sample average growth rate (i.e., a constant). Given the large noise component in forecasts, particularly at longer horizons, the paper calls into question the usefulness of judgment-based medium and long-run forecasts for policy analysis, including for debt sustainability assessments, and points to statistical methods to improve forecast accuracy by taking into account the risk of overfitting.

Book Synopsis Mending the Crystal Ball: Enhanced Inflation Forecasts with Machine Learning by : Yang Liu
Download or read book Mending the Crystal Ball: Enhanced Inflation Forecasts with Machine Learning written by Yang Liu and published by International Monetary Fund. This book was released on 2024-09-27 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forecasting inflation has become a major challenge for central banks since 2020, due to supply chain disruptions and economic uncertainty post-pandemic. Machine learning models can improve forecasting performance by incorporating a wider range of variables, allowing for non-linear relationships, and focusing on out-of-sample performance. In this paper, we apply machine learning (ML) models to forecast near-term core inflation in Japan post-pandemic. Japan is a challenging case, because inflation had been muted until 2022 and has now risen to a level not seen in four decades. Four machine learning models are applied to a large set of predictors alongside two benchmark models. For 2023, the two penalized regression models systematically outperform the benchmark models, with LASSO providing the most accurate forecast. Useful predictors of inflation post-2022 include household inflation expectations, inbound tourism, exchange rates, and the output gap.

Book Synopsis Completing the Market: Generating Shadow CDS Spreads by Machine Learning by : Nan Hu
Download or read book Completing the Market: Generating Shadow CDS Spreads by Machine Learning written by Nan Hu and published by International Monetary Fund. This book was released on 2019-12-27 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: We compared the predictive performance of a series of machine learning and traditional methods for monthly CDS spreads, using firms’ accounting-based, market-based and macroeconomics variables for a time period of 2006 to 2016. We find that ensemble machine learning methods (Bagging, Gradient Boosting and Random Forest) strongly outperform other estimators, and Bagging particularly stands out in terms of accuracy. Traditional credit risk models using OLS techniques have the lowest out-of-sample prediction accuracy. The results suggest that the non-linear machine learning methods, especially the ensemble methods, add considerable value to existent credit risk prediction accuracy and enable CDS shadow pricing for companies missing those securities.
