We provide a single example that illustrates all aspects of linear, integer and dynamic programming, including such concepts such as value of perfect and imperfect information. Such problems, though extremely plausible and realistic are hardly ever discussed in managerial economics.

Operational risks have become increasingly important for banks, especially against the background of growing IT dependency and the increasing complexity of their activities. Further-more, the corona pandemic contributed to the increased risk potential. Therefore, banks have to back these risks with own funds. There are currently three measurement approaches for determining the capital requirements for operational risk. In recent years, and especially during the Great Financial Crisis of 2007/2008, however, some of the weaknesses inherent in these approaches have become apparent. Thus, the Basel Committee on Banking Supervision revised the current capital framework. Therefore, this article examines the various measurement approaches, addresses inherent weaknesses and moreover, presents the future measurement approach developed by the supervisory authorities.

Banks are currently facing numerous challenges. In addition to the ongoing cheap money policy of the European Central Bank, a regulated market environment and a rapidly progressive digitization, financial institutions are increasingly confronted with topics such as sustainability and climate protection. From the latter derive not only risks but also chances for banks. Sustainability risks can impact different risk categories such as market risks, credit risks, operational risks, and liquidity risks. Moreover, reputational risks can occur in this context. This is especially important as bank customers constantly develop a greater awareness of ecological issues, and thus, develop increasing expectations on how companies – like banks – deal with issues like climate protection and sustainability. For this reason, we will start with a theoretical explanation of the key words and then present the results of our customer survey to highlight the current expectations of bank customers in the context of climate protection. Based on this, we formulate recommendations for banks on how to generate a competitive advantage by engaging in climate protection and by taking sustainable actions.

The current phase of low interest rates poses major challenges for banks. A continuous decline in the interest result, which is so important for the profitability of banks, has been observed for years, as it is becoming increasingly difficult for banks to generate sufficient income from the interest margin. This is partly due to the European Central Bank’s expansive monetary policy. However, other factors, such as advancing digitization, also play a role here. The structure of the German banking market and the mostly strong focus of German banks on interest-bearing business are also increasingly becoming a problem. Still, the question arises, whether the current phase of low interest rates is actually a serious threat to banks or whether they are complaining at a high level.

Functional business valuation is the prevailing doctrine in the theoretically well-founded German-language literature, because the value of a company is primarily dependent on the purpose (function) of the valuation. This paper deals with one of the three main functions of business valuation: the argumentation function. This is where the argumentation value of the business is determined. The argumentation function is the function that has been the least theoretically developed and accepted to date, but is probably the most commonly used one in the real world. This article shows for the first time in the English-language literature the core ideas of the theoretical foundation of this function.

The COVID‑19 pandemic has had a great impact on the economies of the EU, also with regard to the future of EU climate policy. The plan to rebuild and support the EU economy seems to place less emphasis on environmental issues as the main focus has been shifted to a quick economic recovery. One of the issues discussed in this context is the continued operation of the EU ETS. From this perspective, empirical research devoted to a thorough analysis of the impact of the EU ETS is of particular importance. At the same time, the current economic literature lacks any econometric analyzes devoted to the issues in question that would use detailed and reliable databases on EU ETS like the one provided by the Wegener Center for Climate and Global Change. The aim of this paper is to make a preliminary assessment of the effectiveness of the EU ETS in terms of reducing the actual emissions while preserving the economic growth of EU member states. The extensive empirical analysis is focused on examining the issues in question for different phases of the EU ETS and various groups of EU economies that vary in terms of economic development and the overall air pollutant emission.

Banks and financial service providers are currently facing numerous challenges due to the ongoing cheap money policy of the European Central Bank, an increasingly regulated market environment and a rapidly progressive digitization. The ongoing decline in interest income and the stagnating of a banks commission income are currently leading to a reduction of a banks total income. In addition, there is digitization that brings numerous new competitors into the market and changes the core business models of banks. As a result, the general conditions in the financial sector change fundamentally and continue to do so in the near future. Moreover, the behaviour and expectations of bank customers have changed in a way that factors such as “convenience”, “flexibility” and “speed” have become increasingly important for them. For this reason, we will start with a theoretical overview of the status quo and the current challenges banks are facing and then present the results of our customer survey to highlight the current expectations of bank customers. Based on this, we formulate recommendations for banks on how to meet their customers’ expectations.

The paper attempts to rectify what appear to be popular but elementary misconceptions about the concept of consumer surplus in the context of Marshallian demand curves. It is primarily addressed to teachers of microeconomics at the undergraduate level or in MBA programs of business schools. The main text informs the reader about the model/context and the results we are concerned with, all of the latter being a comprehensive teaching note, relegated to an appendix of the paper. Thus, the potential instructor may use the main text to motivate himself/herself and at the same time inform his/her students as to the topic i.e. the rehabilitation of consumer surplus as an exact measure of welfare from the stand-point of cost benefit analysis. Thereafter the appendix can be referred to for a more formal presentation. The technical results contained in the appendix begin by showing that willingness to pay is the area under the demand curve if and only if consumers are surplus maximizers. The last result in the appendix is a theoretically ‘happy ending’ since it shows that for purposes of applied economics, budget constrained preference maximization implies surplus maximization and hence for such consumers, willingness to pay is indeed the area under the demand curve up to the quantity consumed.

Family businesses are an important part of every economy. They are characterized by long traditions that combine aspects such as trust and reliability, as well as by features such as innovativeness, foresight, long-term focus and flexibility. Both family businesses and the entrepreneurial families themselves do have some weaknesses and face current challenges like digitization, internationalization and demographic change. These issues must be kept in mind in order to constantly develop appropriate solutions that will help them survive and thrive in the market. Moreover, the high relevance of the family in a family business is associated with opportunities – for example, when a family strategy with clear values, roles and goals is defined, and a so called family business governance is developed.
