Big Data in Finance
介绍2019年NBER-RFS大数据会议特刊，定义大数据为大规模、高维度和复杂结构，并展示这些特征如何推动公司金融、市场微观结构和资产定价等领域的创新研究。
Abstract Big data is revolutionizing the finance industry and has the potential to significantly shape future research in finance. This special issue contains papers following the 2019 NBER-RFS Conference on Big Data. In this introduction to the special issue, we define the “big data” phenomenon as a combination of three features: large size, high dimension, and complex structure. Using the papers in the special issue, we discuss how new research builds on these features to push the frontier on fundamental questions across areas in finance—including corporate finance, market microstructure, and asset pricing. Finally, we offer some thoughts for future research directions.
