This paper uses graph-theoretic methods to investigate the causal relationships between agriculture, money, interest rates, prices, and real GDP in 12 countries during the years 1869-1929. We find that agricultural production directly and indirectly causes real GDP in two-thirds of the cases. Monetary shocks also play an important causal role in about half the cases, but unlike agriculture, the causal links are usually indirect through other variables to real GDP. The direct causal link between money and prices is also particularly strong. Between 1869 and 1929, money causes prices in nearly all of the countries in the sample. (c) 2006 Elsevier Inc.
