First-quarter growth is likely "stronger than whatever the government is going to publish at the end of this month", Goldman Sachs chief economist Jan Hatzius told CNBC Friday.
Hatzius says that ISM data, used by Goldman's new Current Activity Indicator, are "consistent with significantly more growth than the GDP" data currently indicate.
Goldman's CAI looks beyond GDP to include labor and industrial production data, among others. "If you want to take a broad view of economic activity it does make sense to cast a net as wide as possible," Hatzius said.
