This paper presents results that indicate that oil price shocks were e
conomically important in explaining movements in industrial production
, and, to a lesser degree, movements in wholesale prices in the period
between World Wars I and II. The framework for analysis is a vector a
utoregressive model estimated using monthly data over 1924.2-38.6 that
employs a financial intermediation variable, a measure of relative oi
l prices, and other variables typically found in small macroeconomic m
odels. The impact of oil price shocks is evaluated through computation
of variance decompositions and an historical decomposition over the 1
929:9-38:6 period.
