The automation of manufacturing processes as a result of the Fourth Industrial Revolution, rendered faster under the influence of the COVID-19 pandemic, leads to a question as to whether small enterprises, and in particular microenterprises, will still be financially self-sufficient. The literature on the subject so far has not provided an answer to this question, and limited access to financial data concerning microenterprises, as well as data on the robotification of labour in these companies, leads to this problem becoming a research niche. Therefore, this paper aims to assess the attractiveness of the operation of microenterprises that provide financial advisory services in the situation of replacing human labour with robots. For that purpose, we performed a simulation of the state of the microenterprise before and after introducing the robotification of services, taking into account the extra tax on robotification. The findings indicate that anticipating the improvement of financial results following the automation of financial services requires taking into account the replaceability of employees in a particular unit, the form of acquiring a robot and a potential increase in the tax burden (with a tax compensating for the lost state income).

Investments and long-term real interest rate in Poland. Study of investment structure, current account and their correlation with long-term real interest rates Jakub Krawczyk, Szymon Filipczak BOOK REVIEWS

From October 2017 the European Union envisages the abolition of the socalled sugar quotas and minimum prices for buying sugar beet. As a consequence of these changes the sugar levies paid by the sugar factories of the Member States will cease to apply. The article identifies the fiscal effects of the abolition of these levies. The European Union and the Member States will lose some of their budget revenues. The structure of Member States' burdens for GNI payments will also change as well as their operating balance relative to the EU budget. Through the change Poland will gain, whereas some large net contributors will lose, i.e. the Netherlands, Sweden and the United Kingdom.

The Market Economy Investor Principle (MEIP) is applied to assess if the public investment becomes public aid. Such assistance is essential for the success of the investment as it can completely or partially contest it. In Poland MEIP is still poorly recognized. The paper presents the concept and possibilities of using MEIP in assessing the effectiveness of public investment. The MEIP can be a versatile and effective tool especially useful for assessing the recapitalization of the broadly understood companies in terms of the market competition distortion. The paper also mentions the objections to MEIP.
