Conditioning can also work to overcome information asymmetries. For instance, Governments may need to better understand the benefits of immunization, and a conditional cash transfer programme that conditions immunization can overcome this information asymmetry. Besides enhancing the public interest, conditionalities may also strengthen the bargaining position of women, whose preferences may be better aligned with the Government’s, but who may lack bargaining power within the household. Conditions also help make the transfers more acceptable to the average taxpayer (de Brauw and Hoddinott, 2008).
