Following an analysis of the relation between a standard Steindlian model of stagnation and Steindl’s own analysis, we modify the standard model by introducing endogenous changes in the markup and a reformulation of the investment function. These extensions, which address significant weaknesses of the standard model, find support in Steindl’s writing and leave intact some of Steindl’s key resul...

This paper studies a two-sector New Keynesian model that captures the hump-shaped response of non-durable and durable spending to a monetary shock when non-durable prices are sticky and durable goods are flexibly priced. Based on the estimated parameters, we show that habit formation and investment adjustment costs are not sufficient to generate the gradual response of non-durable and durable s...

This paper examines the impact of public information in an economy where agents also have diverse private information. Since disclosures by central banks are an important source of public information, we are able to assess how the words of central bankers shape expectations, in addition to their actions. In an otherwise standard macro model, the disproportionate role of public information degra...

Earlier studies of the seigniorage inflation model have found that the high-inflation steady state is not stable under adaptive learning. We reconsider this issue and analyze the full set of solutions for the linearized model. Our main focus is on stationary hyperinflationary paths near the high-inflation steady state. The hyperinflationary paths are stable under learning if agents can utilize ...

This paper offers additional insights on the interactions between economics and politics in Portugal. We use an unexplored data set consisting of monthly polls on vote intentions for the main political parties in Portugal, since 1986. Results indicate that: (1) socialist governments had less electoral support than social democratic governments; (2) social democratic governments enjoyed a honeym...

In this paper, we study the potential of stocks as a hedge against inflation for different investment horizons. We show that stocks can be a hedge against inflation even if stock returns are negatively correlated with unexpected inflation shocks, and only moderately positively related to expected inflation. Depending on the investment horizon, the optimal hedge ratio can be either positive or n...

Using data from 15 EU countries for 1974-2004, with various specifications and estimation methods this paper gives strong support to the idea that the aggregate inflation-output gap or inflation-unemployment rate relationship is not linear because inflation is relatively more sensitive to markets and regions that are close to a capacity constraint. Accordingly, inflation is not only related to ...

Using a New-Keynesian framework, we investigate how far the inflationary processes in member states of EMU cause regional price levels to converge. We fail to produce hard evidence of the present existence of such an adjustment mechanism, notwithstanding that inflation in some countries tends to converge towards the euro area level. Overall, inflation persistence has declined significantly over...

This paper studies the joint business cycle dynamics of inflation, money growth, nominal and real interest rates and the velocity of money. I extend and estimate a standard cash and credit monetary model by adding idiosyncratic preference shocks to cash consumption as well as a banking sector. The estimated model accounts very well for the business cycle data, a finding that standard monetary m...

Our main result is that dynamic new-Keynesian (DNK) models with firm-specific capital feature a substantial amount of endogenous price stickiness. We use this insight to assess the desirability of alternative interest rate rules, and make the case for combining active monetary policy with interest rate smoothing and/or some responsiveness of the nominal interest rate to real economic activity. ...
