The aim of this study is to verify the validity of Barro-Ricardo equivalence in Czech conditions with the help of experimental methods. Ricardian equivalence, in which case consumers postpone consumption under lower taxation, is a basic assumption of many studies dealing with intertemporal decision making and has important implications for government tax policy. Using nonparametric methods and panel data regression, we find that Ricardian equivalence does not hold in general. Our results suggest that taxation has a significant impact on consumption decisions. Over the life cycle, a tax cut increases consumption on average by 28.7% of the tax credit. Conversely, a tax increase causes a 27.8% increase in consumption on average. Using individual consumption time series, we find that approximately 70% of the tested individuals behave contrary to Ricardian equivalence. Our results show that a change in tax levels affects consumption in subsequent periods.

The issue of minimum wage is highly topical in the context of the so-called minimum wage controversy, which contradicts the attitude of the neoclassical school. The aim of this paper is to analyse the effect of minimum wage increase together with effects of changes in other exogenous variables such as GDP growth rate, inflation rate, unemployment compensation and other social benefits on the real unemployment rate in the Czech Republic in 2006-2018. Linear regression models are tested using the Cochrane-Orcutt method. The effect of minimum wage increase on the rate of unemployment proved to be insignificant in the period 2006-2018. A negative effect of GDP growth rate was confirmed in 2006-2018, while unemployment benefits seemed to have a positive effect on the unemployment rate. The results show a negative effect of increasing minimum wage on the unemployment rate of women in 2011-2018, in line with the neoclassical theory. The conclusions of this paper have significant economic implications for minimum wage policy.

Frank Hyneman Knight made a significant contribution to neoclassical economics. The paper aims to examine his economic theory and political philosophy. The first part outlines the life of Frank Knight. The second part examines his thesis titled "Risk, Uncertainty and Profit" (1921). The third part analyses "The Economic Organization" (1933). The fourth part discusses the book "The Ethics of Competition" (1935). The fifth part takes a look at the political philosophy in the book "Freedom and Reform" (1947). The sixth part highlights the significance of Knight for the Chicago School.

Very low real rates of interest observed in modern economies might be caused by the fact that the natural rate of interest declined to a zero level. This article shows that a zero or a negative natural interest can be explained by the Böhm-Bawerkian and neoclassical theory. Firstly, two senses of time preference are introduced in a discounted utility model, and key determinants of the zero interest rate on the side of time preference are discussed in detail. Secondly, a simple general equilibrium model with fixed intertemporal endowment is presented. Within this model, a decreasing shape of the income stream is identified as a major source of zero interest along with a low intertemporal elasticity of substitution in consumption. Even in the world of zero or negative natural interest, it might be optimal to be a lender. The last section focuses on the role of marginal productivity of capital in the model, stressing the role of this phenomenon on one side and time preference on the other in lowering the natural rate of interest to a zero level.

The commentary defends the central idea of current institutional social research - that institutions are significant variables influencing the human action regarding the resource allocation. This idea was strongly opposed by the scientific board of the Czech economic faculty (institutionally oriented economic research was labeled as needless). The goal is to open the debate about this issue and ask the opponents to formulate concrete objections. Theoretical arguments and empirical examples are raised in favor of the institutional economics.

Neoclassical environmental economics, ecological economics and free market approaches to environmental protection are currently three main schools of thoughts that are systematically focused on interactions between the society and the environment. They all have strong defenders as well as opponents. Although the environmental economics is still considered as mainstream, the critique from alternative approaches is increasing. The goal of the article is to briefly introduce main thoughts of all three schools and their interactions. The intensity of mutual interactions in the last decade was investigated via the analysis of articles published in high-rated journals.

Currently, if speaking about the theoretical background of the environmental policy, most of environmental economists have neoclassical economics in their minds. State regulation of private activities by means of restrictions, commands, taxes and fees is usually seen as the only one way to reach the high quality of the environment. It is believed, that due to market failures market forces are not able to solve the environmental problems. Actually, these are the main arguments for state interventions into the private negotiations about environmental issues. But are these assumptions correct from the methodological point of view? Is the state regulation really the only one way to solve the environmental problems? In this paper we try to signify the main methodological problems of neoclassical economics and to identify, how to solve environmental problems from the point of view of other economic school of thoughts. The development of theoretical aspects of environmental issues was not fetched up in 60's. and 70's with neoclassical conclusions, but it continued in 80's and 90's with free-market-environmentalism. This theoretical background contains the methodology of Austrian school of thoughts, Public Choice theory and new institutional economics. In the present environmental policy, theoretical conclusions of these school of thoughts are (intentionally) marginalized. At the end of this paper we discuss the interdependence between environmental degradation and economic growth. Is the economic growth bad or good for environmental protection? To answer this question we follow the modeling approach.

During 1930s and 1940s Josef Macek developed monetary theory leading to monetary policy recommendations which are deeply influenced by macroeconomic theory of John Maynard Keynes. Macek became leading Czech left-wing keynesian. His theory of money was nominalist and similarly to J. M. Keynes and G. Cassel he elaborated the concept of managed fiat money. He critisized and disapproved the quantity theory of money. In his monetary theory and his monetary policy conclusions he was a forerunner of contemporary post-keynesian monetary theories. Money supply is in his monetary theory highely endogenous and he expressed certain doubts about effeciency of monetary policy measures as antirecessionary remedy.

This paper examines Friedrich von Wieser's theory of the socialist or communist planned economy. It identifies in Wieser's Law of Power (1926) the abiding interests that stimulated his attempt to use Carl Menger's theory of subjective value to present a theory of socialism, first in Natural Value (1889) and later in Social Economics (1914). It discusses his conception of a unit of marginal utility, or "natural value," as the basic unit of economic calculation in his imputation theory and his use of that building block in his consequent theory of production and distribution in a socialist economy. Lastly, it argues that Wieser's theory attempts to socially objectify subjective values and is actually a return to a pre-Mengerian supply-side, real cost approach to the theory of value. Wieser's theory of economic calculation under socialism thus represents a failure to understand the radical contribution of Menger's value theory to the theory of exchange.
