This dissertation thesis deals with relation between labour market and monetary policy referring to two fundamental theoretical concepts -- natural rate hypothesis (or NAIRU) and unemployment hysteresis hypothesis. The first chapter outlines the most frequent values of the Phillips curve, the fundamental model of macroeconomics theory in the relation between the labour market and the monetary policy. The following chapter deals with the exogenous NAIRU concept which works as natural unemployment rate approximation. The unemployment hysteresis deals with the NAIRU as endogenous variable which is dependent on preceding imbalanced situations on labour market. The thesis outlines the main causes of the hysteresis: capital scrapping effect, role of the long-term unemployment and the insider-outsider hypothesis. The third chapter also comprises simple econometric tests of both particular mechanisms and the hysteresis itself based on usual unit roots tests. The results show the hysteresis using data from both the Czech Republic and Central and Eastern Europe countries (CEEC). The fourth chapter deals with monetary-political implications of the unemployment hysteresis. The practical part of the thesis is based on two hypotheses of the relation between inflation (policy interest rate) and NAIRU. The last chapter based on the VAR model outlines short-term relations between the labour market and monetary policy variables. Long-term relations are tested by both the co-integration analysis and vector error correction model (VECM). These models are examined on the data from the Czech Republic and Poland (2000-2013). The thesis also applies pooled regression estimate for ten CEEC. The results show that the monetary policy does have impact on the labour market not only in the short-term but also in the long-term period and thus they confirm the hysteresis hypothesis

The dissertation thesis is devoted to the topic of investment with emphasis on their position within the transmission mechanism of inflation targeting. It discusses starting-points of inflation targeting regime, individual transmission channels of monetary policy including their connections, and routes through which the central bank may influence the investment. There are analyzed selected investment theories and other theoretical models that are associated with the investment. Factors, whose changes may induce changes in investment, are derived using the intersection of these two analyzed aspects. They are variables, which flow from a theoretical analysis of transmission channels, as well as variables, that are not directly accented within these channels, but they can be affected by the central bank. Even factors, that are not within the competence of the central bank, are included among the variables. Using available data, sources of investment variability are verified on data for the Czech Republic. Basic empirical analysis of time series and correlation analysis are performed and the vector error correction model is compiled.

The goal of this thesis is to evaluate the readiness of the member states of NAFTA to adopt a common currency or some other narrower monetary arrangement. This readiness is evaluated by the lens of Optimum currency areas theory (OCA). This thesis provides an overview of the basic OCA criteria, estimates the Optimum Currency Areas Index as a tool to assessing the fulfillment of OCA criteria and readiness of the countries of NAFTA to adopt a common currency or some other narrower monetary arrangement along the lines of the European monetary union. The results of this research indicates that Canada vis a vis USA is in state of advanced convergence and Mexico converges towards the USA economy. We can say that on the basis of OCA criteria the common currency arrangement is likely to be possible in the near future.
