The paper examines in detail revised estimates of unemployment and gross national product for the United States before 1929. It first discusses the nature of the revisions to each series and contrasts the assumptions underlying the new data with those underlying the Kuznets GNP series and the Lebergott unemployment rate series. It then examines the business cycle properties of the new prewar estimates. In analyzes the volatility and serial correlation properities of the new macroeconomic series and investigates the Okun's Law relationship between unemployment and GNP, concluding with an evaluation of the assumptions underlying the old and new data.
