Experimental economics is an established method of generating controlled and replicable empirical knowledge. It is complementary to other empirical methods in the social sciences. The research infrastructure for laboratory experiments is very good in Europe and also in Germany. One useful instrument would be to develop a short socio-economic questionnaire with questions already used in surveys that experimental economists could use to administer to their participants. The analyses of the selectivity of subject pools would then be an easy task. However, among experimental economists no standard exists yet, which limits the comparability of respective data sets. An effort shall be undertaken to "create" such a common questionnaire. The status quo with regard to data reporting is that no standard has emerged yet. There exists one data repository (in the United States) where data of experiments are collected and are freely available. Building up a data archive that integrates (merges) existing data is very laborious and requires substantial scientific inputs of interested researchers.

Purpose – The paper is intended to identify the role and activity of universities in building up business environment infrastructure in Poland. It analyses centres that support innovation processes and entrepreneurship co-established by higher education institutions, such as technology and academic incubators, technology transfer centres, and science and technology parks. Research method – The research methods include: a critical analysis of subject-matter literature, the analysis of the existing data (reports and expert opinions), and three casual interviews with leaders of innovation and entrepreneurship centres in Poland. Results – After a period of dynamic development (which ended in 2012), the number of business support institutions is declining. The trend is observed, in particular, amongst technology parks and incubators. On the other hand, the engagement of universities in the development of technology transfer centres is growing while the population of university start-up incubators remains stable. The number and power of entrepreneurship and innovation support centres are strongly correlated with the economic strength of regions and their position as academic centres. University and business collaboration has been expanding together with the density of regional relationships. Originality / value – The article assesses the state and quality of operation of the academic business environment and its transformation in the last decade.

The article features results of the assessment of the multiplier effects for the national economy from the implementation of construction project of the first stage of production facility of the Dniester HPP for the period 2010-2019. For this purpose, macroeconomic statistics were processes, on whose basis an information system of primary and calculated indicators was created using the data from the project documentation, which became the basis for calculations. A methodological approach was developed to assess multiplier effects at the macroeconomic level using the input-output balance, which is reflected in the symmetrical "input-output" table. The authors highlight the main indicators, through which the impact of the implementation of the construction project of the Dniester HPP on Ukraine's economy is manifested, and which allow assessing its socio-economic significance: the multiplier of the output growth of the economic activity "Construction" at the expense of project investments, the GVA multiplier for all economic activities from project investments, and the GDP multiplier (public expenditure multiplier). According to the implemented approach, multiplier effects for the economy are calculated via additional output growth, additional value added growth, and GDP growth on project investments. Based on the obtained results, it is proved that: 1) the implementation of the construction project of the first stage of the production facility of the Dniester HPP had made it possible to accumulate a multiplier effect for Ukraine's economy, confirming in practice the theory of multiplier effects and proving the efficiency of public capital investments; 2) to the greatest extent, the multiplier effect from the additional investment growth in this project is generated within the economic activity "Construction", which is explained by increased demand for domestically produced construction products.

In developing countries, rapid urbanisation has led to an increase in the demand for transport, aggravating problems of pollution, congestion and accidents. Increasing public transport availability is one way of addressing these problems. In the Indian city of Kolkata, buses cater to a large number of people in the metropolitan area and are run by private operators as well as by the state government. Corporations owned by the state, known as state transport undertakings, operate buses. There is, however, a general complaint that the state-run buses show poor performance in nearly every sphere, including inefficient staff, irregular service, ill-maintained fleet, etc. The objective of this study is to look at the physical, financial and manpower performance of the different state transport corporations to find out whether these corporations operate efficiently. The results indicate that there is underutilisation of fleet, defective employment policy, wrong purchase policy, poor revenue generation, etc. on the part of all the corporations.
