Hartman (1972) and Abel (1983) showed that when firms are competitive and there is flexibility of labour relative to capital, marginal profitability of capital is a convex function of the stochastic variable (e.g., price); by Jensen’s inequality, this means that uncertainty increases the...

The understanding of the economy's aggregate growth patterns is a fundamental objective of economic growth theorizing. However, the micro constructions are strongly linked to economic growth and so cannot be neglected in such process. This paper is concerned with this problem, proposing a formal...

This paper examines labor adjustments in ten Portuguese banks after the ownership transfer to the private sector. The results show that the restructuring process is a very complex phenomenon, with firms exhibiting diverse adjustments in terms of either speed or path. In addition, our findings...

We estimate the effect of demand and price uncertainty on firms' investment decisions from a panel of manufacturing firms. Uncertainty measures are derived from firms' subjective qualitative expectations. They are close to their theoretical counterparts, the variances of future demand and price...

It is often argued that the baseline New-Keynesian model, which relies solely on the notion of infrequent price adjustment, cannot account for the observed degree of inflation sluggishness. Therefore it is a common practice among macro modellers to introduce an ad hoc additional source of...

Consisting of teams working with firm level data, the International Study Group on Exports and Productivity has used comparable micro level panel data for 14 countries and a set of identically specified empirical models to investigate the relationship between exports and productivity. The...

This paper investigates the effects of monetary policy on firms\u2019 investment behaviour. The analysis relies on a comprehensive database of Belgian firms covering all sectors of economic activity and firms of all sizes. We proceed in two steps. First, we estimate a reduced-form investment...

This paper presents a simple model of state-dependent pricing that allows identifying the relative importance of both nominal and real factors in price rigidity. Using two rich datasets consisting of a large fraction of the price quotes used to compute the Belgian and French Consumer Price...

This paper examines the degree of price rigidity in Belgian consumer prices, using a large database. As to the observed degree of rigidity, the results reveal a substantial amount of heterogeneity, not only across but also within product categories. While prices turn out to be perfectly flexible...

Due to the increasing discussion about liberalisation in the piped water industry municipal authorities in several European countries consider modifications of their water utilities’ structure such as legal constitution, business objectives or private participation. The purpose of this paper...
