Gas Electron Multiplier (GEM) technology is being used in various applications, particularly in high energy physics experiments. The GEM is known as a reliable detector in high radiation environment which can maintain high temporal and position resolution. GEM foil is the basic part of the detector which consists of a composite material (polyimide and copper). Large size GEM foil has complex mechanical structure and asymmetries which mainly arises due to formation of the HV sectors in the foil. These asymmetries become very relevant when large size foils are stretched to build a detector.

Many contributions have analyzed the implications of underdeveloped financial markets for economic growth and efficiency of production, emphasizing their role as a source of misallocation and highlighting their negative impact on firm dynamics and innovation. The phenomenon is particularly severe in economies characterized by high reliance on debt financing, asymmetric information and imperfect capital markets.

This paper looks at structural change as one additional source of decline in the wage share. First, we provide a decomposition of changes in aggregate wage shares into changes due to variations in output composition and in sectoral wage shares for nine OECD countries between 1977 and 2010. We show that the rise in the service sector is a relevant factor in explaining the fall of the wage share, at least for some countries. Next, we develop a two-sector Kaleckian growth model consisting of the service and manufacturing sectors.
