摘要:
Motivated by the recent gold price boom, this paper examines whether an asset bubble exists in the gold market. We approximate gold's fundamental value using several econometric models and apply a Markov regime switching Augmented Dickey-Fuller (ADF) test which has substantial power for detecting explosive behavior. Although our results are sensitive to the specification of the fundamental value, we show that a model accounting for the current European sovereign debt crisis accurately tracks the gold price observed in the market. We also note that inflation in a general commodity price index and gold ETF demand have a potential to explain the price trajectory. (C) 2014 Elsevier Inc. All rights reserved.
