We determine the second best rule for the inflation tax in monetary general equilibrium models where money is dominated in rate of return. The results in the literature are ambiguous and inconsistent across different monetary environments. We derive and compare the optimal inflation tax solutions across the different environments and find that Friedman's policy recommendation of a zero nominal ...

In this paper we apply the wavelets methodology to the analysis of the comovements of for some MENA countries from June 1997 until March 2005. We decompose weekly stock market returns into di¤erent time scale components using the non-decimated discrete wavelet transform and then analyze the relationships among these variables at the di¤erent time scales. Keywords : Stock market returns, Wavelet...

We re-examine the empirical relevance of the cost channel of monetary policy (e.g. Ravenna andWalsh, 2006), employing recently developed moment-conditions inference methods, including identi…cation-robust procedures. Using US data, our results suggest that the cost channel e¤ect is poorly identi…ed and we are thus unable to corroborate the previous results in the literature. Keywords: Cost chan...

We study forward-looking economic models assuming that agents take one step ahead expectations looking back k time periods. We show that the dynamics of the economy with such an expectation function are characterized by the coexistence of perfect foresight and nonperfect foresight cycles. The stability of all these periodic solutions under bounded rationality is related to the stability of the ...

We examine robustness of stability under learning to observability of exogenous shocks. Regardless of observability assumptions, the minimal state variable solution is robustly stable under learning provided the expectational feedback is not both positive and large, while the nonfundamental solution is never robustly stable. Overlapping generations and New Keynesian models are considered and co...

The papers in this symposium address the issue of multiple equilibria that can be induced by monetary policy in models with capital accumulation. In particular they examine how the “Taylor Principle”, under which interest rates respond more than proportionately to increases in inflation, can generate multiple equilibria. They also explore the design of policies to avoid the problem of multiple ...

In this paper the authors explore the ability of simple monetary models with bounded rationality to account for the joint distribution of money and prices. They impose restrictions on the size of the mistakes agents can make in equilibrium and argue that countries with high inflation are likely to satisfy these restrictions. Their computations show that the model with bounded rationality does n...

When (a) holds it is easy to characterize dissipativity in an explicit way. In fact it is easy to prove that the set of assumptions (a)-(b) is equivalent to (a)-(b*) with (b*) There exists R > 0 such that IorFi(t, Rei) d t < 0 ; 1 < i _ < 3 ; where le l,e2,e31 denotes the canonical basis of ~3. As a consequence of the theorem we obtain a result that is reminiscent of Massera 's theorem for plan...
