Initially, social safety nets were intended for three purposes: Institutional reform, to make the adjustment programs feasible politically, and most importantly,
poverty reduction. The social safety net is a
club good, which follows from it being excludable but non-rival. Critics argue that SSN decreases the incentives to work, gives no graduation encouragement, tears down communal ties, and places a financial burden potentially too heavy to carry in the longer run. Furthermore, it has shown very difficult to decrease the SSN once it has been extended. Casper Hunnerup Dahl, a Danish economist, finds that there is a strong negative correlation between the generosity of
OECD welfare states and the work ethic. The Swedish economist Martin Ljunge finds that an increasingly generous sick leave system leads younger Swedes to stay more at home than their older peers. However, proponents argue that the case is quite the opposite, that even tiny transfers are used productively and often invested, be it in education, assets, social networks, or other income-generating activities. == History ==
