Query: The durations of recession and prosperity: does their distribution
  follow a power or an exponential law?   Following findings by Ormerod and Mounfield, Wright rises the problem whether
a power or an exponential law describes the distribution of occurrences of
economic recession periods. In order to clarify the controversy a different set
of GDP data is hereby examined. The conclusion about a power law distribution
of recession periods seems better though the matter is not entirely settled.
The case of prosperity duration is also studied and is found to follow a power
law. Universal but also non universal features between recession and prosperity
cases are emphasized. Considering that the economy is basically a bistable
(recession/prosperity) system we may derive a characteristic (de)stabilisation
time.
