This paper characterizes a robust optimal policy rule in a simple forward-looking model, when the policymaker faces uncertainty about model parameters and shock processes. We show that the robust optimal policy rule is likely to involve a stronger response of the interest rate to fluctuations in...

We study the problem of a policymaker who seeks to set policy optimally in an economy where the true economic structure is unobserved, and he optimally learns from observations of the economy. This is a classic problem of learning and control, variants of which have been studied in the past, but...

Accounting and Financial methods are useful techniques for business, but their objective study should be inserted in the wider scope of Social Science. Historical issues determine policies and these ones, themselves, configure taxes and other environmental variables. Taxes, interest rates and...

Focused especially on the causes, Woods elegantly discovers in the tradition of the Austrian School of economics that the main culprit for the creation of crises is the monetary system’s nature. As he goes, this is a system that allows a process of artificially expanded money supply which...

The European sovereign debt crisis revived the discussion concerning the pros and cons of exchange rate adjustment in the face of asymmetric shocks. Exit from the euro area is to regain rapidly international competitiveness. Exchange rate stability with structural reforms could be beneficial for...

This paper seeks to develop an optimal fiscal policy rule for the Colombian economy that interacts with the monetary policy in order to stabilize the product and inflation gap. It proposes a Dynamic Stochastic General Equilibrium model (DSGE) with nominal rigidities and proposes a fiscal rule...

In this paper, I analyse the synchronisation of business cycles within the European Union (EU), as this is an important ingredient for the implementation of a successful monetary policy. The business cycles of twelve EU countries and two sub-groups of countries are extracted for the period...

The objective of this paper is to point out that dollarization may be used as a signaling device. To this end, we introduce into a standard monetary policy model two types of governments: good and bad. Information is asymmetric, the government type is uncertain and the policy of the bad...

After decades using monetary aggregates as the main instrument of monetary policy and having different varieties of crawling peg exchange rate regimes, Colombia adopted a full-fledged inflation-targeting (IT) regime in 1999, with inflation as the nominal anchor, a floating exchange rate, and the...

This paper models the US dollar as a global currency and focuses on the effects of US money supply shock upon China's economy. The special roles of US dollar as a global currency and the special institutional arrangements of China are investigated. Given a positive US money supply shock, both...
