This paper studies the falsiability of the hypothesis of Nash behavoir, for the case of a finite number of players who choose from continuous domains, subject to constraints. The results obtained here are negative. Assuming the observation of finite data sets, and using weak, but non-trivial,...

En este trabajo se propone una metodología para cuantificar la centralidad de los agentes que participan en el mercado interbancario, bajo un enfoque de juegos cooperativos. La metodología utiliza diferencias de valores de Shapley en juegos de transacciones con y sin restricciones de red...

La literatura referente a los modelos de inflación y política monetaria anti-inflacionaria del tipo denominado Inflation Targeting (IT) ha reforzado una opinión popular: que la inflación tiene poca o ninguna relación con el aumento de la cantidad de dinero. Esta opinión es contraria a una...

In an economy conducted under an Inflation Targeting regime, the output gap becomes one of the most important variables to guide monetary policy. Defined as the difference between observed and potential or non-inflationary output, the gap is a measure of the state of aggregate demand and,...

Uno de los hechos estilizados más recientes alrededor del mundo es que, después de varias décadas, se está convergiendo a una inflación baja y estable. Algunos países ya llegaron a su estado estacionario en este sentido y otros aún están en proceso de desinflación. Dado que la...

To evaluate whether transparency is beneficial, it is usual to assume that the central bank may choose one of two options, opacity versus truthful communication. However, the monetary policymaker may have incentives to misrepresent private information so as to reduce economic volatility by...

The adoption of a managed regime assumes that interventions are relatively successful. However, while some authors consider that foreign exchange interventions are ineffective, arguing that domestic and foreign assets are close substitutes, others advocate their use and maintain that their...

To date, there is still great controversy as to which exchange rate model should be used or which monetary channel should be considered, when measuring the effects of monetary policy. Since most of the literature relies on structural models to address identification problems, the validity of...

We study the existence of a monetary policy transmission mechanism through banks in Colombia, using monthly banks’ balance sheet data for the period 1996:4 – 2012:12. We obtain results which are consistent with the basic postulates of the bank lending channel (and the risk-taking channel)...

We set a dynamic stochastic model for the interbank daily market for funds in Colombia. The framework features exogenous reserve requirements and requirement period, competitive trading among heterogeneous commercial banks, daily open market operations held by the Central Bank (auctions and...
