Who Persistently Creates Jobs? Absolute versus Relative High-Growth Firms

2017

This paper examines the economic contribution of high-growth firms after their high-growth event. While the central role of high-growth firms for job creation is well-established, little is known about their dynamic development in coming periods. We address this question for the first time by comparing absolute with relative growth measures and use data on private firms in Bulgaria for three consecutive 3-year periods (2001-2004, 2004-2007, and 2007-2010). Next to calculating transition probability matrices to investigate growth in employees in coming periods, we model future employment growth by means of a two-part model with separate equations for the probability of survival and exit as w…

Photovoltaic facade: Comparison of actual technologies

2017

This article aims to establish the economic contribution of a photovoltaic system placed on a façade of a building, replacing traditional elements such as windows and glass-cement walls with active elements. The aim is to compare the behavior of next-generation systems, which favor architectonical integration, with traditional ones. Two novel systems have been taken into account: a dye sensitized solar cell (DSSC) and blue and grey thin film silicon panels. Different generation systems have been tested and compared in terms of efficiency and fill factor.
