The coexistence of fiat money (cash) and digital monies constitutes a system of parallel currencies as media of exchange. This paper asks whether a new (digital) currency is essential: Does a new currency allow for a better resource allocation even if a fully accepted currency is in circulation...

In recent years, cryptocurrencies such as Bitcoin have emerged, in upcoming years, corporate currencies such as Libra (Diem) and central bank digital currencies will emerge even in low-inflation developed economies. Using the dual currency search model of Kiyotaki and Wright (1993), we show how...

We develop a small open economy model with capital, sticky prices, and a simple form of financial frictions. We compare welfare levels under three alternative rules: a domestic inflation-based Taylor rule, a CPI inflation-based Taylor rule, and an exchange rate peg. We show that the superiority...

We develop a small open economy, New Keynesian model that incorporates a financial accelerator in combination with liability dollarization. Applying a Ramsey-type analysis, we compare the welfare implications of an optimal monetary policy under flexible exchange rates and an optimal capital...

We investigate the problem of how to make welfare comparisons of income distributions hen a population allocation problem (how a population should be optimally divided over families for given resources) adds to the usual income allocation problem. Pro-family and anti-family stances are...
