This article examines the use of logistic classification methods for the id
entification and prediction of postwar U.S. business-cycle expansion and co
ntraction regimes as defined by the National Bureau of Economic Research (N
BER) reference turning-point dates. We present a coherent theoretical frame
work for this task using measures of discriminatory information. The analys
is encompasses model selection, parameter estimation, and classification de
cision rules. We examine the performance of logistic procedures in reproduc
ing the NBER regime classifications and in predicting one and three months
ahead using leading-indicator variables. Our models are shown to provide su
bstantially more accurate business-cycle regime predictions than Markov swi
tching specifications.
