Abstract
The article investigates the significance of time, the nature of capital, and the role of technological progress in economic processes. The presented analysis of the three economic categories makes use of the theoretical achievements of notable representatives of the Austrian School of Economics, for whom a creative entrepreneur was the main protagonist of the interactions taking place in the economy. The above-mentioned economic categories, taken together, are for him the foundation of human activity. The time factor is of great importance for man – individuals constantly analyse historical events so as to attain success in contemporary economic reality, and in the future. Capital is the basis for economic calculation, which underpins all entrepreneurial activity. Technological progress, which happens in time and requires considerable capital outlay, is the driving force of economic growth.
