Does money affect happiness and self-esteem? The poor borrowers' perspective in a quasi-natural experiment

Research on the nexus between life satisfaction and income has looked at lottery winners or postcommunism transition to document that exogenous changes in income generate effects of the same sign on happiness. In this paper we consider the unfortunate tsunami event as a negative lottery and examine the effects of the tsunami related income losses, net of the most ample possible set of concurring factors, on life satisfaction and self-esteem of a sample of Sri Lankan microfinance borrowers. Our empirical findings help to discriminate between various effects of material damages and monetary losses, both having strong significant impact on the dependent variables. Our contribution to the literature is in: i) identifying an exogenous shock which is temporary and does not suffer from voluntary participation bias (unfortunate "winners" of the negative lottery, exactly as control sample, did not decide to buy the lottery ticket); ii) testing the money-happiness nexus on a sample of individuals close to the poverty line.
