We present a set of practical applications of the household sector stress testing approach used at the Czech National Bank. The aim is to test households’ ability to repay their loans in the event of extremely adverse economic developments. Besides this, the household sector stress test methodology has so far been used for two other purposes: (i) to construct a simple reverse stress test and explore the sensitivity of Czech households to a rise in loan interest rates and a decline in income, and (ii) to provide some supportive evidence for the calibration of debt service-to-income limits.

The paper is aimed at assessing efficiency of adopted measures of the concept of flexicurity in Sweden and Czech Republic in 2006-2015. It examines hypothesis that the matching process can be made more efficient by increasing the labour market flexibility. The Beveridge curve depicting the relationship between the unemployment and job vacancies is used to demonstrate a change in efficiency of labour market policies. The correlation analysis is used to address possible reasons for weaknesses of active labour market policies. Research findings show a better efficiency of the matching process in a rigid labour market, with the hypothesis being confirmed only for Czech Republic. However, the Czech labour market was fighting against higher imbalances than the Swedish one, throughout the whole period under review, with the most threatened unemployed having been both young and older people.

One of the fundamental assumptions of the efficient market hypothesis and the modern portfolio theory are both Gaussian probability distribution and the independence of returns. This paper provides a brief historical review of efforts dealing with capital markets emphasizing their efficiency and counter-tendencies whose goal was to falsify the assumption of independence of returns and their normal distribution. This paper applies a measure of long-range dependence rediscovered and promoted by Mandelbrot to daily returns of 27 selected stock indices. This measure is called Hurst exponent and was estimated using rescaled range analysis. The results are in line with similar papers stating that the series of daily returns are prevailingly persistent which implies the presence of local trends. Such a finding falsifies the assumption of random walk in stock prices.

The paper deals with the issue of interbank interest rate pass-through into client interest rates offered by banks in the condition of Slovak Republic between 2004 and 2016. We provide an overview of studies of the interest rate relationship analysis in the bank and interbank market. We investigate the interest pass-through from money market rates to various loan and deposit rates. The analysis is carried out using the methodology of cointegration error-correction model, which take into account both the long-term and the short-term aspect of interest rate development. Our results point to considerable differences in the size of the pass-through with respect to either different loan and deposit rates. It has also shown a low rate of immediate transmission, the incompleteness of the pass-through, higher efficiency in the process of interbank interest rates pass-through into the interest rates on loans, and we can conclude that the process of interest rates pass-through in our conditions is relatively stable.

Innovation Decisions in Uncertain Business Environments of CEE Countries Corporate innovations are a central part of a country’s economic activity. They foster and improve competitiveness, which ultimately leads to economic growth and progress. In this study, we focus on the post-communist European region, where corporations operate under uncertain conditions. Utilizing a sample with almost 100,000 firm level observations over the period from 2001 to 2013, we analyse effects of uncertainty steaming from corruption environment on innovation decisions of the Central European private firms. We find that domestic firms and firms with dispersed ownership innovate less when business and municipal uncertainty conditions increase. When firms are unsure whether they will be blocked by local bureaucrats from capitalizing on their innovation, they scale down their efforts. However, this result disappears for firms with foreign majority ownership. We hypothesize that foreign controlled firms have cleared all uncertainties before they entered the foreign market.

Three methodological errors in the economics of authors’ rights and their consequences.Using a realistic and holistic approach, this theoretic contribution corrects three main assumptions of the economic theory of copyright and explains why they hinder the proper understanding of its role. First, authors’ pieces of work are like a public good that needs the protection of copyright to overcome the free rider problem. However, a piece of work can be spread only with a medium good or service. Such a pair might not possess the properties of a public good like nonexcludability and nonrivalry. The second assumption that copyright enables authors to charge the price above marginal costs was rejected as too simplistic because the copyright affects different markets with pairs work + medium variably and moreover, it ensures for authors a non-market revenue. The complexity of copyright also explains why the third assumption that copyright can be modelled as a single index is meaningless. A new framework for optimisation behaviour of authors is offered.
