Homo oeconomicus - an overcome assumption?

The neoclassical approximation of human behaviour is the content of model homo oeconomicus assumptions that have been subjected to criticism from sociologists, psychologists and economists. Work corresponds negatively to the question whether the neoclassical concept is an overcome model. Criterion for overcome model we consider poor predictive ability of the model and its replacement by an alternative concept. Although we reject the possibility of falsification and verification of the assumptions of the model due to the subjective nature of the data from decision process based on Hayek theory of mind, we argue that more realistic assumptions of the model leads to better quality predictions. We, therefore, are concerned with the theory of bounded rationality, the results of behavioural experiments and Becker's extended utility function. Good predictive ability of the model despite the unrealistic assumptions we explain by the simplicity of getting information on the market and by the theory of imitation. On the example of an imaginary city, we show why inefficient patterns of behaviour maintain on the market. We conclude that the model homo oeconomicus is not an overcome model thanks to allowing the extension of assumptions leading to higher-quality predictions of human behaviour.
