KEY POINTS:
The New Zealand Institute of Economic Research is having a bet each way on whether the Reserve Bank will raise interest rates on Thursday.
Between January 2004 and December 2005, the bank raised the official cash rate (OCR) from 5 per cent to 7.25 per cent and another quarter-point raise is expected this week.
Although the institute says the market "overwhelmingly" believes the OCR will rise, it will not be surprised at a "no change" decision.
