Abstract. Recently, Jean Imbs and colleagues have claimed that much of the purchasing power parity puzzle can be explained by ‘aggregation bias’. This paper re-examines aggregation bias. It clarifies the meaning of aggregation bias and its applicability to the PPP puzzle; demonstrates that the size of the ‘bias’ is much smaller than suggested if explosive roots in the simulations are ruled out; and shows that the presence of non-persistent measurement error data can make price series appear less persistent than they are. After correcting for small-sample bias, half-life estimates indicate that heterogeneity and aggregation bias do not help to solve the PPP puzzle.
