This note makes two comments on recent NNS models. First, it disputes the way physical capital has been introduced into these models, arguing that this leads to the dubious postulate that the cost of adjusting physical capital stock is an order of magnitude lower than the cost of changing...

This Paper explores the stability properties of the steady state in the standard two-sector real business cycle model with a sector-specific externality in the capital-producing sector. When the steady state is stable then equilibrium is indeterminate and stable sunspots are possible. We find...

Using aggregate US and Canadian data, this paper examines the implications for the empirical assessment of market structure and exogeneity of productivity shocks of correcting the Solow residual for variation in capacity utilization. In contrast to most studies, not accounting for capacity...

We construct a dynamic equilibrium model where there is costly search in the goods market and the labor market. Incorporating shocks to money growth and productivity, we calibrate the model to the US time series data to examine the model's quantitative predictions on aggregate variables and, in...

In this paper we evaluate the empirical relevance of learning by private agents in an estimated medium–scale DSGE model. We replace the standard rational expectation assumption in the Smets and Wouters (2007) model by a constant gain learning mechanism. If agents know the correct structure of...

We estimate a New-Neoclassical Synthesis business cycle model with two investment shocks. The first, an investment-specific technology shock, affects the transformation of consumption into investment goods and is identified with the relative price of investment. The second shock affects the...

This paper analyses the adjustment mechanism in the euro area. Results show that the real exchange rate (REER) adjusts in such a way to redress cyclical divergences and that after monetary unification REER dynamics have become less reactive to country-specific shocks but also less persistent. It...

This paper considers alternative interpretations of the Normal Cost Hypothesis of industrial pricing behaviour. It shows first that the hypothesis can interpreted as implying that actual unit costs are an endogenous variable, for which some measures of normal unit costs are an appropriate...

This paper analyzes several important aspects of price behavior using disaggregated weekly data on prices of supermarket products in Colombia between 1991 and 1994. The analysis shows that despite hight and persistent rates of inflation in the economy, price quotations persist on average for two...

This discussion paper led to an article in 'Journal of Economic Theory' (2014). Volume 150, pp. 778-814.<P> We propose behavioral learning equilibria as a plausible explanation of coordination of individual expectations and aggregate phenomena such as excess volatility in stock prices and high...</p>
