Ecological economics and the problem of sustainable development: the methodology of economic cybernetics [pp.4-7]
Ramazanov S.K.
Purpose and subject of research
The article aims at research and development of an integrated model of
sustainable noosphere, secure and sustainable development of socio-ecological and
economic processes.
Research methodology
The study used formal mathematical methods, the method of economic and mathematical modeling.
Value results
Formal mathematical methods of nonlinear science adequate to describe,
analyze and simulate the decision-making processes. The dynamics of the
interaction processes and interferences (ie dynamics of synergetic processes)
cognitive or emotionally modes (group of essential parameters or variables)
between themselves and the emotional and cognitive events with each other can be
described by a system of equations of Lotka-Volterra.
Conclusions
The paper proposes an innovative model of sustainable development
noosphere socio-ecological-economic and humanitarian system, generalized
synergetic model dynamics with uncertainties and risks.
Mathematical modeling of business behavior under pulse investments
[pp.8-15]
Vlasenko L.A., Lysenko Yu.G., Rutkas A.G.
Purpose and subject of research
We consider linear and nonlinear models of business behavior under external
pulse investments to basic production assets of enterprises.
Research methodology
In the article used methods and models of decision making, mathematical
models of the dynamics, evolutionary models with implicit and degenerate
differential equations.
Value results
The article investigates the linear and nonlinear dynamics model production
with external impulse investment in fixed assets of enterprises. Analyzed deceleration and acceleration rates of output growth, the effects of stabilization of
fixed assets, investment optimization dynamics pulsed with quadratic performance.
Conclusions
Obtained formulas of overall production and basic assets contain jumps at
moments of investment earnings. We analyze the deceleration and acceleration of
business growth, the stabilization of basic assets, the optimization of dynamics of
pulse investments with quadratic cost function.
Application of entropy approach to the analysis of income distribution
[pp.16-21]
Merkulova T.V., Bitkova T.V.
Purpose and subject of research
Two modifications of a system dynamics model are developed in order to
study different types of a taxpayer’s behaviour – notably, opportunistic tax evasion
and soft adaptive ones.
Research methodology
A generic model by M. Allingham and A. Sandmo, based on “homo
economicus” conception, implying that an agent is guided in his behaviour by
maximization of expected utility, shows that taxpayer’s choice to evade taxes
depends on tax rates and tax inspection parameters, among which the most
important are the probability of inspection and penalty degree (penalty rates).
Value results
Computations have confirmed that with relatively low penalties and middle
level of inspection opportunistic behaviour is more effective for taxpayers. When
opportunistic motivation is mass-spread, this type of behaviour becomes
predominant, which leads to substantial losses of the state. Such a state of tax
environment is characterised by the conflict of interests of the parties: tax evasion
is profitable for the agents and un-remunerative for the state.
Conclusions
The results of multiple experiments are discussed and comparative
advantages and effectiveness of tax behaviour are analyzed regarding joint
(declared + shadow) taxpayer’s income and real/net state revenue.
Investigation the influence of exchange rate channel of transmission mechanism on the ukrainian economy real sector [pp.22-36]
Lukianenko I.G.
Purpose and subject of research
For the modern economic model the transformation of the tradition
monetary transmission mechanism is relevant that demands in-depth analysis of
the effectiveness of the monetary channels and the determination of the optimal
structure of the transmission mechanism especially for the developing countries.
The integrated assessment of the changes in the Ukrainian monetary
transmission mechanism, in-depth analysis of the effectiveness of the separate
channels and the investigation of the peculiarity of the impulses transmission by
the exchange rate channel in short run and long run for Ukrainian economy is the
main object of this study.
Research methodology
A theoretical and empirical framework is proposed based on the monetary
theory, including the new features of the monetary transmission mechanism and
the time series analysis with vector error correction models.
Value results
The statistical analysis, analysis of the impulse responsible functions and
the variance decomposition on the base of the elaborated vector error correction
model for the exchange rate channel had allowed to estimate its influence on the
real sector of the Ukrainian economy in short run and long run and empirically
improve the hypotheses about special feature of this channel for Ukraine. The
present study provides a starting-point for further research in the effectiveness of
the transmission mechanism channels for the developed and developing countries
for the purpose of the determination of the effective directions of the monetary
policy for the stimulation of the economic growth.
Conclusions
The framework has proven to be useful to show the specific and the
dominant role of the exchange rate channel for the Ukrainian economy and nonsignificant
function of the other channels for the Ukraine which demands not only
of the improvement of the exchange rate policy but also the transformation of the
structure of the Ukrainian monetary transmission mechanism.
Choice approach to the valuation of the financial institution in м&a
contracts using the analytic hierarchy process [pp.37-42]
Gricenko K.I., Yaremenko N.S.
Purpose and subject of research
The purpose of research is rationale for the choice approach to valuation of
financial institutions, the most appropriate in mergers and acquisitions. The object
of study is the choice of approach to valuation of financial institutions in mergers
and acquisitions.
Research methodology
The study used the methods of valuation of financial institutions that are
legislated in Ukraine, namely: cost, comparative and revenue.
Value results
The relevance of the topic chosen is usually in the works of scholars choice
approach to valuation is based on logical reasoning without the use of specialized
tools for decision making. According to the National Standard number 1 "General
Principles of valuation of property and property rights" in Ukraine legislated
mandatory application of the income, expenditure and comparative approaches to
assessing the value of any object. Therefore, the question of choice reasoned
approach to the valuation of financial institutions in mergers and acquisitions are
opened.
Conclusions
The results of the study concluded that, if necessary, to take account of
mergers and acquisitions investment value of the financial institution objectives as
an integrated facility and its development potential is the most appropriate
evaluation procedures focus on methods of income approach. Although he has a
number of shortcomings of traditional methods of valuation, however, is the most
appropriate contractual M & A, takes into account the valuation of financial
institutions in mergers and acquisitions and can be the basis for further research in
the area of valuation of financial institutions in mergers and acquisitions.
Evaluation of the microeconomic system's stability [pp.43-47]
Kasyanovа N.V.
Purpose and subject of research
The purpose of research is the development of methodical approach to
determining the level of economic stability on the basis of industrial building
system of integrated indicators.
Research methodology
A theoretical framework is based on methods of system analysis in
management of the insurance company development, innovative control methods.
Value results
The paper examines the economic sustainability of the enterprise from the
perspective of the functional stability characteristics (parameters), highlights
various components of sustainability: financial, technological, organizational,
commercial and social. It is proposed to evaluate the stability of the economic
system using the stability of indexes and the balanced proportions of the enterprise
developing.
Conclusions
The proposed assessment of the economic viability is viewed from the
perspective of sustainability components. Within the range of the components,
elements that characterize the use performance of their potential, should be
provided. The methodical approach of constructing a system of integrated
indicators for each of these types of resistance, makes it possible to carry out a
comprehensive assessment of the industrial enterprise's economic viability, and
identify an approaching to the bifurcation point.
