摘要

我们采用神经网络(NN)方法--长短期记忆(LSTM)--研究 2008 年大衰退和 COVID-19 衰退期间的农产品价格。我们的分析表明,与动物性商品相比,玉米和大豆等植物性商品在经济衰退期间的结构性断裂更多,波动性更高。不同商品的价格反应各不相同,玉米首先对两次经济衰退做出反应,而牛奶价格则独立于其他价格,最后从金融衰退中恢复,最先从疾病引发的衰退中恢复。对经济衰退期间商品行为的深入了解有助于投资者和研究人员进行趋势预测和衰退准备。

Comparing the great recession and COVID-19 using Long Short-Term Memory: A close look into agricultural commodity prices

Comparing the great recession and COVID-19 using Long Short-Term Memory: A close look into agricultural commodity prices

We employ a neural network (NN) approach—Long Short-Term Memory (LSTM)—to study agricultural commodity prices during the 2008 Great Recession and the COVID-19 recession. Our analysis reveals more structural breaks and higher volatility in plant-based commodities like corn and soybeans during recessions compared with animal-based commodities. The price reactions varied among commodities, with corn responding first to both recessions, while milk price, which was found independent of other prices, recovered last from the financial recession and first from the disease-induced recession. This insight into commodity behavior during recessions can aid in trend prediction and recession preparation for investors and researchers.
