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...

A Schumpeterian growth model is constructed for an economy where wages are determined by union-firm bargaining. It is shown that the economy is subject to cycles in which capital, output and employment vary in fixed proportion. These increase through saving and capital accumulation until a new technology is introduced, at which moment they fall sharply due to obsolescence of capital. The labour...

This paper considers the problem of how to construct price indexes on a panel data set. First a suitable panel data set is constructed by merging Eurostat’s Harmonized Index of Consumer Prices (HICP) with a cross-section of OECD data. Second, seven different methods for constructing price indexes on a panel are proposed. These are then applied to the merged HICP/OECD data set. Temporal and spat...

The present paper analyzes propagation of shocks to food and energy prices in 46 countries with data from the period 1999-2010. The empirical evidence suggests that in only one of the countries considered, a shock to the price of either energy or food shows no propagation to the prices of the goods and services included in the core inflation measure. In general, the propagation effect of food p...

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 ...
