A significant problem in the collection of responses to potentially sensitive questions, such as relating to illegal, immoral or embarrassing activities, is non-sampling error due to refusal to respond or false responses. Eichhorn & Hayre (1983) suggested the use of scrambled responses to reduce...

This paper evaluates the evolution of European venture capital investments since 1990, using the distribution dynamics methodology. It tests and rejects the hypothesis that the international allocation of venture capital investments is driven by a pathdependent process of agglomeration, in which...

Markov chains have experienced a surge of economic interest in the form of behavioral agent-based models that aim at explaining the statistical regularities of financial returns. We review some of the relevant mathematical facts and show how they apply to agent-based herding models, with the...

This work analyzes the saving and consumption behavior of agents faced with the possibility of unemployment in a dynamic and stochastic life cycle model. The intertemporal optimization is based on Dynamic Programming with a backward recursion algorithm.The implemented uncertainty is not based on...

We review and simultaneously introduce a convenient statistical concept for the mathematical representation of the Statistical Activity Cost Theory (SACT) introduced by Willett (1987 and 1988). Further, we discuss, and present a critique of, a variety of statistical models with respect to long...

In this paper we propose a novel approach in analysing the impact of changes in sovereign credit ratings on stock markets. We study the evolution of a segmented form of the stock market index for several crisis-hit countries, including both European and Asian markets. Such evolution is modelled...

The misestimation of rating transition probabilities may lead banks to lend money incoherently with borrowers' default trajectory, causing both a deterioration in asset quality and higher system distress. Applying a Mover-Stayer model to determine the migration risk of small and medium...

The aim of this paper is to investigate regional convergence of income at district level in Slovakia, and to answer the question of whether Slovak districts converge or diverge over time, and across different sectors of the Slovak economy. Our analyses are based on monthly income data on median...

This article examines the impact of digital transformation on changes in the sectoral structure of Ukraine's economy, other post-communist countries, and countries with highly developed economies. Firstly, we estimate the structural changes and differences in the sectoral model by gross...

We propose a new view of initial nonresponse bias in longitudinal surveys. Under certain conditions, an initial bias may "fade-away" over consecutive waves. This effect is discussed in a Markovian framework. A general contraction theorem for time inhomogeneous Markov chains is presented. The...
