ABSTRACT
This paper analyzes a regulator's optimal strategic delay of resolving banks when the regulator's announcement of the intervention delay endogenously affects the depositors' run propensity. ...Given intervention, the regulator either liquidates the remaining illiquid assets (“prompt corrective action”) or continues managing the assets at a reduced skill level (“resolution under receivership”). In either case, I show that if the regulator tolerates fewer withdrawals until intervention, the depositors may react by preempting the regulator: they run on the bank more often ex ante. A policy of never intervening can leave the bank more stable than a conservative intervention policy.
We analyze a two-country economy with complete markets, featuring two national currencies as well as a global (crypto)currency. If the global currency is used in both countries, the national nominal ...interest rates must be equal and the exchange rate between the national currencies is a risk-adjusted martingale. Deviation from interest rate equality implies the risk of approaching the zero lower bound or the abandonment of the national currency. We call this result Crypto-Enforced Monetary Policy Synchronization (CEMPS). If the global currency is backed by interest-bearing assets, additional and tight restrictions on monetary policy arise. Thus, the classic Impossible Trinity becomes even less reconcilable.
We consider a setting where agents can choose between two currencies to conduct their goods purchases. The usage of either currency comes with currency-specific transactions costs. For example, ...purchasing some goods with cryptocurrencies rather than dollars is easier and may avoid taxes. We explore an extension of Schilling-Uhlig (2019), allowing for asymmetry in transaction costs as well as dollar-bitcoin exchange fees. Agents alternate in their role as buyers and sellers, necessitating currency. A central bank steers the dollar inflation path, while bitcoins are in fixed supply. We characterize the nonstochastic equilibrium and the resulting exchange rate dynamics.

•We provide a model of an endowment economy with two competing, but intrinsically worthless currencies (Dollar, Bitcoin) serving as medium of exchange.•We show a fundamental pricing equation, which ...in its simplest form implies that Bitcoin prices form a martingale.•“Mutual impatience” rules out Bitcoin speculation. Price volatility does not invalidate the medium-of-exchange function.•The Bitcoin block rewards are not a tax on Bitcoin holders: they are financed with a Dollar tax.•We discuss monetary policy implications, Bitcoin production via the proof-of-work competition, taxation of Bitcoin production, welfare implications and entry of new cryptocurrencies. We characterize the range of equilibria and provides specific examples.
We provide a model of an endowment economy with two competing, but intrinsically worthless currencies (Dollar, Bitcoin). Dollars are supplied by a central bank to achieve its inflation target, while the Bitcoin supply grows deterministically. Our fundamental pricing equation implies in its simplest form that Bitcoin prices form a martingale. “Mutual impatience” implies absence of speculation. Price volatility therefore does not invalidate the medium-of-exchange function. Bitcoin block rewards are not a tax on Bitcoin holders: they are financed with a Dollar tax. We discuss monetary policy implications, Bitcoin production, taxation, welfare and entry, and characterize the range of equilibria.
Profesora, investigadora y artista, Susan Schuppli es directora del Centre for Research Architecture de Goldsmiths, Universidad de Londres. También es directora del consejo de Forensic Architecture, ...donde está afiliada como artista-investigadora. A través de su trabajo, Schuppli examina pruebas materiales de conflictos que van desde guerras hasta desastres medioambientales y cambio climático. Es autora de Material Witness (MIT Press, 2020). En 2016 fue galardonada con el Premio Infinity del ICP. Su trabajo anterior como artista-investigadora y escritora exploró la evidencia material, concretamente las formas en que testigos no-humanos participan en juicios y testifican en tribunales en causas relacionadas con acontecimientos históricos, en particular relacionadas con la violencia política, los conflictos étnicos y los crímenes de guerra. Actualmente, a través de su investigación y su producción artística expande estas investigaciones para examinar cómo los sistemas medioambientales y las transformaciones provocadas por el calentamiento global están generando nuevas formas de evidencia: creando, en efecto, un archivo planetario de testigos materiales. Su trabajo actual se enfoca en aprender del hielo y las políticas del frío.
This paper shows the existence of a central bank trilemma. When a central bank is involved in financial intermediation, either directly through a central bank digital currency (CBDC) or indirectly ...through other policy instruments, it can only achieve two of three objectives: a socially efficient allocation, financial stability (i.e., absence of runs), and price stability. In particular, a commitment to price stability can cause a run on the central bank. Implementation of the socially optimal allocation requires a commitment to inflation. We illustrate this idea through a nominal version of the Diamond and Dybvig (1983) model. Our perspective may be particularly appropriate when CBDCs are introduced on a wide scale.

The introduction of a central bank digital currency (CBDC) allows the central bank to engage in large-scale intermediation by competing with private financial intermediaries for deposits. Yet, since ...a central bank is not an investment expert, it cannot invest in long-term projects itself, but relies on investment banks to do so. We derive an equivalence result that shows that absent a banking panic, the set of allocations achieved with private financial intermediation will also be achieved with a CBDC. During a panic, however, we show that the rigidity of the central bank's contract with the investment banks has the capacity to deter runs. Thus, the central bank is more stable than the commercial banking sector. Consumers internalize this feature ex-ante, and the central bank arises as a deposit monopolist, attracting all deposits away from the commercial banking sector. This monopoly might endanger maturity transformation.
La presente tesis se desarrolla como una investigación y posterior aproximación metodológica para abordar territorios sometidos abruptamente a cambios que generan un trauma, espacios en crisis que ...devienen cuando el individuo a causa de un evento específico cambia su manera de habitarlo para poder sortear diversos obstáculos producidos por forzosas nuevas programáticas y límites territoriales. En la etapa de investigación se desarrolla un set de preguntas para la construcción de antecedentes teóricos que otorgan una palabra sobre la idea de paisaje/landscape y su relación con el habitante a propósito de un evento generado por un desastre natural; luego en la etapa de análisis esta relación es interrogada cualitativamente a través de las evidencias narrativas que genera, en particular aquella del relato biográfico, bajo la premisa de que si el lugar es un espacio vivenciado, las narrativas de sus habitantes son el sustrato de análisis que engloba las diferentes contingencias del espacio en crisis, estas narrativas en sus diferentes manifestaciones sobreviven al acontecimiento mismo del desastre natural entregando evidencias de la relación del hombre con este nuevo espacio. Situando el análisis en un campo de estudio real, donde el trauma del terremoto del pasado 27/02 persiste aún hoy, se visita la comuna de San Pedro de la Paz en la provincia de Concepción durante el mes de septiembre del año 2010 para la recolección de entrevistas, formato que permite obtener de primera fuente información de un hecho situado, información singularizada y acotada a un territorio, la información obtenida de las entrevistas es testimonio que de la conjunción entre evento e individuo aparece el espacio, éstas son posteriormente sometidas a una serie de procedimientos metodológicos de codificación y representación gráfica, para presentar los hallazgos en la discusión final./
