80% reduction of greenhouse gas emissions: analysis of czech energy industry development until 2050
Rečka, Lukáš
The goal of European Union’s Energy Roadmap 2050 is to reduce greenhouse gas emissions (GHG) by 80% compared with the baseline of 1990. The presented paper evaluates the implications of several pathways to reach this goal, and compares them to the existing State Energy Policy, which may lead to a reduction of greenhouse gas emissions by 66.5%. Using the TIMES energy partial equilibrium model, we analyse the reference scenario based in the existing State Energy Policy (SEK) and three alternative low-emission scenarios that will reach the 80% GHG emission reduction target by 2050, which follow three different pathways of the nuclear energy developments (N35, N45 and N-opt). In all the scenarios, the resulting technology and fuel mix is a product of total production costs minimisation, with respect to the exogenous technological constraints. The cost minimization does not include any external costs of energy transformation, and, therefore, cannot be taken as social optimum considering all costs and benefits associated with energy transformation.

Knowledge transfer through academic entrepreneurship in the Czech Republic
Macháček, Vít ; Srholec, Martin
The study brings first quantitative evidence on the scale and scope of knowledge transfer through academic entrepreneurship in the Czech Republic. The main finding is that Czech academics do not shy away from taking on entrepreneurial opportunities. Admittedly, this is in a sharp contrast with the image of weak entrepreneurial spirit in academia that prevails in general public based on statistics showing low payments of business enterprises for contractual research and licensing fees to research organizations. The results are discussed with regards to implications for public policy.

A global comparison of Czech and Slovak academic journals based on their Impact Factor (IF) and Article Influence Score (AIS)
Münich, Daniel ; Škoda, Samuel
We compare the scores in the widely used citation index of academic journals known as Impact Factor (IF) with the lesser known but more sophisticated index Article Influence Score (AIS). There is a positive correlation between the relative IF and AIS scores within fields, but the spread is quite high. The difference between the IF and AIS scores is caused by differences in the extent of journal self-citation and in the academic importance of the journals from which journal articles are cited. Czech publication output in relatively major journals tends to be concentrated in journals with a lower AIS than IF. These articles also tend to be concentrated in a rather small number of international journals. In many fields, Czech publication output is concentrated in Czech and Slovak journals, most of which have relatively low AIS and IF. The IF and AIS of some Czech journals are entirely outside the natural range of scores worldwide.

The tax system reduces motivation to return to work among mothers with young children: recommendations and evaluation
Šatava, Jiří
In the Czech Republic, the overall taxation of work, i.e individuals' income tax together with social security and health insurance contributions, places a heavy burden even on the relatively low earnings of so-called second earners in households, i.e. partners with lower earnings. These peoples' work activity is, however, generally very sensitive to the level of taxation. A large group of these earners is made up of mothers with young children. Mothers who are the second earner in their household are subject to a participation tax rate (PTR) up to 30 % higher than their partners, and yet a higher PTR results in lower motivation to work. Women with children and low earning potential are subjected to the highest PTRs in comparison with their partners.

Political competition in local governments and public procurement
Palguta, Ján
Municipalities in the Czech Republic manage 23.9% of the total public expenditure (approximately 10% of the GDP), with approximately half of these funds redistributed through public procurement. This is a very significant amount of public resources that should be given due attention. This analysis demonstrates that the composition of municipal governments significantly influences the process of public procurement. Our methodology allows to interpreting the estimated relationships as causal, rather than as mere correlations.

Quality of publication output of scientific fields in Slovakia: an international comparison
Jurajda, Štěpán ; Kozubek, Stanislav ; Münich, Daniel ; Škoda, Samuel
This study covers in detail the publication output in scientific journals in Slovakia, based on articles published in the years 2010 – 2014 and included in the Web of Science (WoS) database and compares it with the output of 11 different countries. For our comparison, we have used the narrowly defined scientific fields used by the WoS to categorize the journals included in the database. The study compares both total publication output and outstanding publication output, i.e. the number of articles published in top scientific journals in the given field, based on their reputation in the academia.

Political party donors on the public procurement market
Palguta, Ján
Entrepreneurs who make donations to political parties in the Czech Republic have a considerable share in the public procurement market. From 2007 to 2013, political donors were awarded 16.3 percent of public procurement contracts, which amounts to 16.6 percent of the contracts value. On average, the annual value of public procurements awarded to political donors was 32.8 billion CZK, which amounts to 0.7 percent of the GDP. Our analysis cannot determine whether contracting authorities select political donors using less transparent tender procedures in order to choose effective contractors who have proven themselves to the contracting authority in the past, or whether the political donations play a part in the selection process.

A national comparison of the academic publication output of the Czech Academy of Sciences: quantity vs quality and co-authorship
Jurajda, Štěpán ; Kozubek, Stanislav ; Münich, Daniel ; Škoda, Samuel
This study maps out in detail the contribution made by the Czech Academy of Sciences (CAS) to the publication output of the Czech Republic for journals listed in the Web of Science (WoS) database. The comparison covers not only the share of the total publication output, but also the share of the excellent publication output, i.e., publications in top-tier journals of respective fields enjoying the most academic prestige. A comparative look at the period 2010-2014 shows that in the vast majority of scientific fields with representation from the CAS scientific teams, the CAS is significantly more focused on publishing in the most prestigious international journals of the WoS database than are others in the Czech Republic. Research cooperation by the CAS in the form of co-authorship takes place at the national level in various fields with differing levels of intensity, as well as differing in the qualitative focus of such cooperation. The sources for this study include the unique bibliometric data processed during the 2015 exercise, the ‘R&D Evaluation of CAS units for 2010-2014’.\n\n
