The IMF estimated that Iceland's economy could slid into a mild recession in 2008. Meanwhile the rate of inflation is estimated to reach 3,3 percent (link).
The empirical data has shown that Iceland experienced one of the highest coefficients of fiscal revenue elasticity, whether it is measured in terms or relative changes in private consumption or in terms of effective real exchange rate. On the other hand, rigorous tax reform in previous decade returned a soaring growth of fiscal revenue which reflects the broad range of revenue elasticity as well as the effects of tax cuts on supply side of the economy and fiscal parameters.
