Most relevant studies have developed models that predicted the probability of business failure within 1 year using financial ratios. Although a few studies have attempted to use nonfinancial information, they did not provide empirical evidence that this addition can improve the prediction performance of a model. To address these problems, this study proposed a model that uses not only accounting variables but also construction market and macroeconomic variables to predict failure probability from 1 to 3 years. We examined the effects of combinations of these variables on the business failure prediction performance of construction contractors in the United States, as well as compared the effects of combinations of these variables between three models which predict business failure within 1, 2, and 3 years. This study developed a prediction model using a long short-term memory (LSTM) recurrent neural network (RNN), which is a deep- learning algorithm. The results showed that the prediction model using both the construction market and macroeconomic variables had approximately 2%, 3%, and 4% higher prediction performance compared with that using only accounting variables when predicting within 1, 2 and 3 years respectively. These mean that the business failure prediction model had superior prediction performance from a long-term perspective when the construction market and macroeconomic variables were used in addition to accounting variables. The results of this study are expected to provide empirical evidence regarding the effect of input variable selection on the prediction performance for each prediction period, and useful references for improving performance of predicting business failure of construction contractors.
