From a theoretical perspective, the output gap is probably the most comprehensive and convincing concept to describe the cyclical position of an economy. Unfortunately, for practical purposes, the concept depends on the determination of potential output, which is an inherently unobservable variable. In this paper, we examine whether the real-time estimates of the output gap as published by the OECD can be improved by referring to measures of physical capital capacity utilisation from business tendency surveys. These data relate directly to the stress on the current capacity to produce goods and services and are not revised. Our real-time panel data set comprises 22 countries at an annual frequency with data vintages from 1995 to 2009. We show that the real-time output gaps are informationally inefficient in the sense that survey data available in real time can help produce estimates that are significantly closer to later releases of output gap estimates.

This paper investigates the R&D persistence of R&D active firms in different markets with different intensities of competition, based on firm-level panel data for the period 1996-2008. In a dynamic setting of the empirical model it turns out that persistence is strongly related to market competition (measured by the number of principal competitors). Persistence of R&D expenditures is more likely to be observed in markets with few principal competitors (between 6 and 10) and is very unlikely to be observed in polypolistic type of markets (more than 50 competitors). These results call for a stronger coordination between competition policy and innovation promotion policy, since the former basically aims at larger markets with many competitors, while the latter aims at persistence of R&D efforts and thus markets with fewer competitors.
