# Predicting the next recession



## Overview



Economic recessions are periods of time when an economy shinks.

These periods of time generally costly to businesses and the populace alike.

Deep recessions can be particularly costly to the populace as business downsizing and business failures during recessions generally result in a decrease in available jobs (increasing unemployment).

However, if it was possible to predict a coming recession with some confidence, then it may be possible for business and the populace to prepare and mitigate losses.



We propose to model the change in GDP for the United States to attempt to predict recessions.

A working definition of a recession is two consecutive quarters of decrease in GDP.

Thus, we will use a 2-step ahead forecast in evaluating models.

50 quarters of historical data will be used for training models to predict the next 2 quarters.



## Conclusion

* Various ARMA, VAR and Neural Network models were developed.

* GDP data was very noisy and overall, models were not able to capture variance in this data.

* The univariate model AR(2) performed better than VAR and MLP models.

* An ensemble model appeared to improve the forecasts, but further analysis should be performed (with sliding ASE) since our test dataset consisted of only 2 data points (unfortunately, we did not have enough data to perform this analysis).

* Addition of other exogenous variables with even stronger cross correlations may improve performance of multivariate models.

* In addition, it may be worthwhile to to look for some leading indicators of recession since GDP tends to be a lagging indicator.
