Despite extensive evidence that preferences are often time-inconsistent, there is only scarce field evidence of willingness to pay for commitment. Infrequent payments may naturally provide commitment for lumpy expenses. Multiple experiments in the Kenyan dairy sector show that: i) farmers are willing to incur sizable costs to receive infrequent payments and demand for commitment is an important driver of this preference; ii) poor contract enforcement, however, limits competition among buyers in the supply of infrequent payments; iii) in such a market, the effects of price increases on sales depend on both buyer credibility and payment frequency. Infrequent payments are common in many goods and labour markets, but they may not be competitively offered when contracts are not enforceable.
