The price of a safe asset reflects not only the expected discounted future cash flows but also future service flows, since retrading allows partial insurance of idiosyncratic risk in an incomplete markets setting. This lowers the issuers' interest burden and allows the government to run a...

This paper incorporates a bubble term in the standard FTPL equation to explain why countries with persistently negative primary surpluses can have a positively valued currency and low inflation. It also provides an example with closed-form solutions in which idiosyncratic risk on capital returns...

This paper investigates the tradeoff between competition and financial inclusion resulting from the vertical integration between mobile network and money operators. Joining newly assembled data on mobile money fees through the WayBack machine, with sources on network coverage and financials, we...

We assess the efficacy of systemic risk measures that rely on U.S. financial firms' stock return co-movements with market- or sector-wide returns under stress from 1927 to 2023. We ascertain stress episodes based on widening of corporate bond spreads and narrative dating. Systemic risk measures...

This paper examines how a newly designed global safe asset can mitigate international capital flows induced by flight-to-safety. In the model domestic investors have to co-invest in a safe asset along with their physical capital. At times of crisis, investors replace the initially safe domestic...

The "reversal interest rate" is the rate at which accommodative monetary policy reverses its intended effect and becomes contractionary for lending. It occurs when banks' asset revaluation from duration mismatch is more than offset by decreases in net interest income on new business, lowering...

When is record-keeping better arranged through a blockchain than through a traditional centralized intermediary? The ideal qualities of any record-keeping system are (i) correctness, (ii) decentralization, and (iii) cost efficiency. We point out a blockchain trilemma: no ledger can satisfy all...

This paper studies strategic decision making by a private currency ledger operator, which faces competition from public money and/or other ledgers. A monopoly ledger operator can incentivize contract enforcement across the financial sector by threatening exclusion, but it can also impose markups...

We analyze the relationship between asset price bubbles and systemic risk, using bank-level data covering almost thirty years. Systemic risk of banks rises already during a bubble's build-up phase, and even more so during its bust. The increase differs strongly across banks and bubble episodes....

We develop a generic model of money and liquidity that identifies sources of liquidity bubbles and seignorage rents. We provide sufficient conditions under which a swap of monies leaves the equilibrium allocation and price system unchanged. We apply the equivalence result to the "Chicago Plan,''...
