Presented by Ayushi Bajaj, Monash University


Digital means of payments are getting increasingly popular but they come at a fixed cost, hence are not accessible to everyone alike.  Carrying small change in cash is useful as it gives flexibility in exchange but it is also costly to carry many bills. Besides, cash lends anonymity in exchange, facilitating a shadow sector characterised by tax avoidance. We model these aspects in a monetary model and simulate a currency change policy shock based on the Indian case to study its effects on output, digitisation, and tax compliance. We find a clear short-term loss of output following such a shock. The model also indicates a possible rise in rural-urban divergence due to a deepening of the digital payments divide.
