3/2012 Merike Kukk, Dmitry Kulikov and Karsten Staehr. Consumption sensitivities in Estonia: Income shocks of different persistence

Working Papers of Eesti Pank. No. 3/2012

The Permanent Income Hypothesis (PIH) entails that consumption reacts more strongly to persistent than to temporary income shocks. This prediction is tested using data from the Estonian Household Budget Surveys for 2002-2007. The dataset contains questions which make it possible to distinguish between persistent and temporary income shocks based on the households' own assessment. The estimations confirm that the marginal propensities to consume out of the two income shocks differ, households are forward-looking and seek to smooth consumption. Moreover, the estimated propensities of persistent shocks are of reasonable magnitudes, consistent with the PIH. Further analysis reveals, however, features that are in breach of the PIH. The consumption estimations are affected by lagged temporary income shocks. When income shocks are decomposed into positive and negative values, there is evidence of excess sensitivity to positive temporary shocks.
