This paper introduces the theoretical foundations and the structure of a macroeconometric model for the analysis of compensation schemes. After a brief explanation of the main relationships between technical change and employment, the general structure of the model is outlined with reference to...

Recent finance literature highlights the role of technological change in increasing firm specific (idiosyncratic) and aggregate stock return volatility, yet innovation data is not used in these analyses, leaving the direct relationship between innovation and stock return volatility untested. The...
