Optimal monetary policy under administered prices

This work aims to analyze the interaction and the effects of administered prices in the economy, through a DSGE model and the derivation of optimal monetary policies. The model used is a standard New Keynesian DSGE model of a closed economy with two sectors companies. In the first sector, free prices, there is a continuum of firms, and in the second sector of administered prices, there is a single firm. In addition, the model has positive trend inflation in the steady state. The model results suggest that price movements in any sector will impact on both sectors, for two reasons. Firstly, the price dispersion causes productivity to be lower. As the dispersion of prices is a change in the relative price of any sector, relative to general prices in the economy, when a movement in the price of a sector is not followed by another, their relative weights will change, leading to an impact on productivity in both sectors. Second, the path followed by the administered price sector is considered in future inflation expectations, which is used by companies in the free sector to adjust its optimal price. When this path leads to an expectation of higher inflation, the free sector companies will choose a higher mark-up to accommodate this expectation, thus leading to higher inflation trend when there is imperfect competition in the free sector. Finally, the analysis of optimal policies proved inconclusive, certainly indicating that there is influence of the adjustment model of administered prices in the definition of optimal monetary policy, but a quantitative study is needed to define the degree of impact.

Monetary policy, default risk and the exchange rate

In a country with high probability of default, higher interest rates may render the currency less attractive if sovereign default is costly. This paper develops that intuition in a simple model and estimates the effect of changes in interest rates on the exchange rate in Brazil using data from the dates surrounding the monetary policy committee meetings and the methodology of identification through heteroskedasticity. Indeed, we find that unexpected increases in interest rates tend to lead the Brazilian currency to depreciate. It follows that granting more independence to a central bank that focus solely on inflation is not always a free-lunch.

On the distributive impact of unconventional monetary policy

Logo após à crise financeira de 2007-08 o Federal Reserve interveio para tentar controlar a recessão. No entanto, ele não apenas baixou os juros, como também adotou políticas não-convencionais, incluindo o empréstimo direto para empresas em mercados de crédito de alto nível. Estas novas medidas foram controversas e alguns opositores protestaram porque elas estariam ajudando disproporcionalmente aquelas pessoas ligadas ao sistema financeiro que já eram ricas. Nós utilizamos um modelo DSGE para a análise de políticas monetária não convencional e introduzimos dois tipos distintos de agentes, capitalistas e trabalhadores, para investigar o seu impacto distributivo. Nós encontramos que a política de crédito to Fed foi bem sucedida no mercado de trabalho, o que ajuda mais os trabalhadores, e introduziu um novo competidor no mercado bancário, o governo, o que prejudica mais os capitalistas. Logo, nós encontramos que a política de crédito diminuiu a desigualdade nos EUA.

The interrelationship between monetary policy and the interbank money market during the financial crisis

Die vorliegende Dissertation besteht aus sechs Kapiteln und trägt zur Forschung in den Bereichen der Finanzmarktpolitik und der Geldpolitik bei. Das zweite Kapitel zeigt die Wechselbeziehung zwischen Geldmarktanspannungen und der Stabilität des Finanzsystems auf. Mittels der theoretischen Literatur werden verschiedene Einflussfaktoren einer aggregierten Liquiditätsnachfragefunktion präsentiert. Das dritte Kapitel untersucht den Informationsgehalt der Ergebnisse der Hauptrefinanzierungsgeschäfte für den europäischen Geldmarkt. Unsere Ergebnisse zeigen, dass sich seit der Finanzkrise der Informationsgehalt der Hauptrefinanzierungsgeschäfte in zweierlei Hinsicht verändert hat. Im vierten Kapitel untersuchen wir die Wirksamkeit der Geldpolitik während der Finanzkrise europäische Geldmarktzinssätze zu steuern. Die Ergebnisse deuten auf eine erhebliche Divergenz zwischen den Zinssätzen und den Erwartungen über die zukünftige Geldpolitik hin. Weiterhin finden wir heraus, dass die unkonventionellen Maßnahmen der EZB für einen Rückgang der Euriborsätze von bis zu 60 Basispunkten verantwortlich sind. Das fünfte Kapitel beschäftigt sich mit der Funktionsweise des besonderen geldpolitischen Instrumentariums der Schweizerischen Nationalbank.
