The presented study develops theoretical and methodological foundations for assessing the fiscal sustainability of the constituent entities of the Russian Federation in perspective.Aim. The study aims to develop a systems approach to assessing the fiscal sustainability of the constituent entities of the Russian Federation in the medium and long term.Tasks. The authors analyze the major approaches to assessing the fiscal sustainability of federal subjects and determine the significance of quantitative and qualitative assessment methods in the development of a methodology for assessing the fiscal sustainability of federal subjects in the medium and long term.Methods. This study uses scientific methods of cognition, analysis and synthesis, comparison and analogy, systems and institutional approaches to assess the fiscal sustainability of federal subjects.Results. The authors examine the major approaches to assessing the fiscal sustainability of federal subjects developed by Russian scientific schools and disciplines; approaches used by state and local authorities; approaches to assessing the fiscal sustainability of federal subjects used by international and national rating agencies; foreign experience. In general, this implies the development of a universal system of indicators for assessing the fiscal sustainability of federal subjects.Conclusions. It is substantiated that under the current conditions of new challenges, particularly in the context of the coronavirus pandemic, it is necessary to assess the long-term balance and sustainability of the budgets of federal subjects using a systems approach based on quantitative and qualitative methods, making allowance for the medium- and long-term prospects to make efficient management decisions at different levels of the economic system.

AbstractThe cell cycle is the process by which eukaryotic cells replicate. Yeast cells cycle asynchronously with each cell in the population budding at a different time. Although there are several experimental approaches to synchronise cells, these usually work only in the short-term. Here, we build a cyber-genetic system to achieve long-term synchronisation of the cell population, by interfacing genetically modified yeast cells with a computer by means of microfluidics to dynamically change medium, and a microscope to estimate cell cycle phases of individual cells. The computer implements a controller algorithm to decide when, and for how long, to change the growth medium to synchronise the cell-cycle across the population. Our work builds upon solid theoretical foundations provided by Control Engineering. In addition to providing an avenue for yeast cell cycle synchronisation, our work shows that control engineering can be used to automatically steer complex biological processes towards desired behaviours similarly to what is currently done with robots and autonomous vehicles.

The research aims to measure and analyze the determinants of investment in the Iraqi economy and study the theoretical foundations of investment and analyze the viewpoint of the most important schools of economic thought regarding investment and investment determinants and their effects on economic activity , and by using possible standard models as the results of standard analysis using the joint integration tests of time series . cointegration tests, they have proven the existence of a long-term equilibrium relationship according to the methodology of the results of estimating the short and long-term parameters and the error correction parameter(ECM) , it is moving from a set of explanatory variables towards The dependent variable, while the value of the error correction vector coefficient was negative and significant , as it reached (-0.59%) , which means the fulfillment of the two basic conditions in this parameter , namely : its negative value and the statistical significance . This means that (0.59) of the short-term errors are automatically corrected during the unit of time (year) to reach the equilibrium in the long term, meaning that the investment requires about less then a year (1.6) , that is , approximately a year and 6 days to reach its equilibrium value in the long term , In other words , the previous period deviates from the long-term equilibrium and is corrected in the current by (59%) . This indicates that the adjustment in the model was relatively fast .

Aging Societies

Fiscal sustainability remains a paramount challenge in the Euro Area (EA) countries after the sharp rise in public debt-to-GDP ratios in the aftermath of the financial crisis of 2008. Using data from 11 EA countries over the period 1980–2019, we apply panel data techniques to examine the effects of population aging on fiscal sustainability, controlling for key macroeconomic variables. Our results suggest that the discretionary fiscal policy is strongly persistent, not being consistent with long-term fiscal solvency. Moreover, our results indicate that the fiscal stance is countercyclical for the countries under study and that population aging poses a major challenge for fiscal sustainability. The findings are robust to a different grouping of countries within the sample (core and peripheral countries, relatively old and young countries, and relatively more and less indebted countries). We consider that our results may have some practical meaning for national policymakers and international organizations responsible for regional and global fiscal surveillance and might shed some light on the possible effects that population aging could have on the effort of EA countries to restore public finances on a sustainable basis.

ABSTRACTThe cell cycle is the process by which eukaryotic cells replicate. Yeast cells cycle asynchronously with each cell in the population budding at a different time. Although there are several experimental approaches to “synchronise” cells, these work only in the short-term. Here, we built a cyber-genetic system to achieve long-term synchronisation of the cell population, by interfacing genetically modified yeast cells with a computer by means of microfluidics to dynamically change medium, and a microscope to estimate cell cycle phases of individual cells. The computer implements a “controller” algorithm to decide when, and for how long, to change the growth medium to synchronise the cell-cycle across the population. Our work builds upon solid theoretical foundations provided by Control Engineering. In addition to providing a new avenue for yeast cell cycle synchronisation, our work shows that computers can automatically steer complex biological processes towards desired behaviours similarly to what is currently done with robots and autonomous vehicles.

China's local government debt has risen dramatically bringing risks to China's fiscal sustainability and long term economic growth. Using urban construction investment bonds (UCIBs) issued by local government financing vehicles (LGFVs), we study how intergovernmental fiscal transfers impact the issuance of UCIBs under China's unitary currency system. Applying instrumental variable estimation, we find that special-purpose fiscal transfers per capita are positively associated with the issuance of UCIBs. A one-RMB increase in special-purpose fiscal transfers per capita is associated with an increase in the issuance of UCIBs per capita of 0.282 RMB, whereas regular fiscal transfers (including tax rebates and general fiscal transfers) do not affect the issuance of UCIBs. Furthermore, the effect of special-purpose fiscal transfers on the issuance of UCIBs mainly exists in inland cities rather than coastal cities. This imposes risks of “eurozonization” for the Chinese economy. We also find a deterioration of refinancing in terms of issuing more UCIBs.

Abstract Issue/problem National healthcare systems worldwide are at a critical point due to the fiscal sustainability challenges faced. At the same time, healthcare systems are under pressure to meet the global demand for adaptation of medical innovations arriving into the market persistently. Description of the problem Hospitals often serve as the entry point for new technologies to the healthcare system. It is therefore extremely important that Health Technology Assessments (HTA) are available in timely order to accurately inform decision-makers on both short- and long-term effects of a health technology to avoid inappropriate investments. Hospital based HTA (HB-HTA) was developed to accommodate the need for evidence-based hospital-specific information in a timely manner. A substantial increase in the use of HB-HTA has been observed in the last years. However, only few reports are being published. A database for the structured collection of HB-HTA reports could help the dissemination and collaboration between hospitals. Effects/changes A survey answered by an international group of experts knowledgeable in HB-HTA from eighteen different countries has showed that there is an interest to realize the collection and dissemination of HB-HTA reports on an international scale. However, confidentiality and resources for a database are barriers for the dissemination of HB-HTA reports. The challenge will therefore be to overcome these barriers and design a database containing high quality, comparable and complete HB-HTA reports with proper data security, regular maintenance and user support. Lessons International collaboration in HB-HTA is the key to timely inform decision-makers without compromising the quality of the data or the methodology.
