We show that certain winning bids for certain ebaY auctions obey Benford's Law. One implication of this is that it is unlikely that these bids are subjected to collusion among bidders, or 'shilling' on the part of sellers. Parenthetically, we also show that numbers from the naturally occurring...

We investigate some characteristics of the underground economy in New Zealand by testing for Granger causality between measured and 'hidden' real GDP in that country. We find clear evidence of causality from measured to hidden economic activity, but only weak evidence of causality in the reverse...

Some of the issues which arise if the RESET test is used to validate the functional form of the equations in an allocation model are discussed. The simple application of this test, equation, by equation, is inappropriate on various grounds. The appropriate formulation of the RESET test in a full...

Earlier research by the author indicates a causal relationship from measured real output in New Zealand, to output in the real underground economy. We investigate the possibility of asymmetries in this relationship, and test to see if the response of the underground economy to downturns in real...

We consider non-stationary time-series data for the size of the hidden economy and for tax-related prosecutions in New Zealand. The two series are found to be cointegrated, and there is strong evidence of Granger causality from prosecutions to hidden activity. There is no significant evidence of...

By noting that the Hodrick--Prescott (H--P) filter can be used as the solution to a particular regression problem, we are able to show how to construct confidence bands for the filtered time-series. This procedure requires that the data are stationary. The construction of such confidence bands...
