Alexa, Jiří ; Potužák, Pavel (advisor) ; Chytilová, Helena (referee)
This thesis examines determinants of IT investments and IT penetration rate. The full sample consists of panel data for 69 countries between years 1996 and 2013.We analyze three types of IT devices: smartphones, tablets and PCs. In order to reveal cross-segment and cross-technology differences in the importance of various determinants, separate regression models are estimated on technology-segment level. Installed base per capita, which is used to measure the level of existing capital, is included among independent variables in equations estimating per capita IT investments. Results show that the effect of the level of existing capital is stronger for smartphones and tablets when compared to PCs. Another finding is that commercial segment is less price sensitive than consumer segment. This study also provides several findings regarding other determinants of IT penetration rate and IT investments such as: national wealth, human capital, openness to trade and external knowledge, and business cycles.
