Characteristics of a Logistics-Based Business Model

In companies where excellence in logistics is decisive for the outperformance of competitors and logistics has an outspoken role for the strategy of the firm, there is present what we refer to here as a “logistics-based business model.” Based on a multiple case study of three Nordic retail companies, the purpose of this article is to explore the characteristics of such a logistics-based business model. As such, this research helps to provide structure to logistics-based business models and identifies a way forward for companies for whom logistics and distribution are a major concern for the overall strategy of the firm.     

EEG 2017 — Mehr Markt bei der Erneuerbare-Energien-Förderung?

Within four years now, the German Renewable Energy Resources Act (EEG) has been amended in 2016 for the third time. The main point of the current reform is the extension of bidding schemes to determine the remuneration of renewable power generation. The articles analyses whether or not the expected decrease in costs and improvement of deployment control could ever occur, and considers the critique of thwarting the energy transition and jeopardising the diversity of actors involved in the industry.     

Consumption-related emotions over time: Fit between prediction and experience

Consumers base many decisions on affective forecasts, i.e., predictions about future emotions. These predictions, however, are susceptible to systematic biases. The present paper examines the accuracy of predicting emotional change in the consumer context. The goals of the study were to examine whether predictions of a change in consumption-related emotions fit actual experienced change and whether original predictions are remembered correctly. A two-wave longitudinal survey with 86 consumers in Austria and the UK showed that consumers who had bought shoes overestimated the decrease of positive consumption-related emotions over time. Results indicate that the intuitive theory of adaptation is related to the prediction bias. Moreover, participants misremembered original predictions as more consistent with actual experienced emotions. This hindsight bias hinders consumers from learning from previous prediction errors.     

Regime switching rough Heston model

This model combines two important stylized features of volatility, the rough behavior consistent with a Hurst parameter less than , and the regime switching property consistent with more long-term economic considerations. It is nevertheless highly tractable in the sense of semianalytic formulae for European options, and permits a partial Monte Carlo method of similar computational speed as the semianalytic formula (at an appropriate number of Monte Carlo simulations). While option prices are relatively insensitive to the choice of Hurst parameter, introducing rough volatility allows for a better fit to the at-the-money skew.     

PROPERTIES OF OPTION PRICES IN MODELS WITH JUMPS

We study convexity and monotonicity properties of option prices in a model with jumps using the fact that these prices satisfy certain parabolic integro–differential equations. Conditions are provided under which preservation of convexity holds, i.e., under which the value, calculated under a chosen martingale measure, of an option with a convex contract function is convex as a function of the underlying stock price. The preservation of convexity is then used to derive monotonicity properties of the option value with respect to the different parameters of the model, such as the volatility, the jump size, and the jump intensity.     

The knowledge spillover theory of entrepreneurship

According to the knowledge spillover theory of entrepreneurship, the context in which decision-making is derived can influence one’s determination to become an entrepreneur. In particular, a context that is rich in knowledge generates entrepreneurial opportunities from those ideas. By commercializing ideas that evolved from an incumbent organization via the creation of a new firm, the entrepreneur (human capital) not only serves as a conduit for the spillover of knowledge, but also for the ensuing innovative activity and enhanced economic performance through resource allocation. The knowledge spillover theory of entrepreneurship brings together contemporary theories and thoughts of entrepreneurship with prevailing theories of economic growth, geography, and strategy and therefore explains not just why some people choose to become an entrepreneur, but also why this matters significantly for the economy and society.     

Potential economic variables and actual economic policies in Europe

Ignoring for a moment the debate on whether balanced budget rules are a sensible idea from a macroeconomic point of view, there remains a major problem with tying one’s fiscal policy to econometric estimates of potential variables: their notorious unreliability. With every one of its biannual economic forecasts, the EC provides revised estimates of structural parameters that are crucial components of its macroeconometric models and, by extension, its economic policy advice. This article shows that the EC’s econometric estimates of potential growth variables in Europe have been subject to massive revisions since the financial crisis.     

Ist der Fahrplan der Energiewende noch einzuhalten?

The German energy transition represents a policy-driven, sustainability-oriented restructuring of both supply- and demand-side components of the entire energy system by 2050. Whereas the development of renewable energies in the electricity sector is right on track, due to the feed-in tariffs of the German Renewable Energy Sources Act, many other crucial requirements for a successful transition are not, amongst others the improvement of energy effi ciency and the decarbonisation of the transport sector. Contrary to the public discussion, the primary future challenges do not consist in limiting electricity prices or abandoning feed-in support schemes, but rather in coordinating the variety of actors as well as appropriately matching the different system elements (grids, technologies, energy sectors, demand and supply side, etc.). Much remains to be done. By highlighting some examples like the need to take into account future implications of climate change for the energy sector, the consequences of the current crisis in the European Union’s emissions trading scheme and the need for a cautious adjustment of the EEG, the paper argues that the major challenges regarding the German energy transition mainly go beyond the current policy-driven and short-term discussion of energy prices. Germany’s pioneering attempt to integrate steadily increasing share of non-dispatchable electricity from renewable sources is challenging the stability of the system. Several characteristics in the current selfregulating system are identifi ed and analysed, which reveal themselves as potential weaknesses or shortcomings in the upcoming system.     

The power and peril of board interlocks

In order to compete, firms must constantly gather and assess information that will help them identify and evaluate emerging opportunities. Their social context is instrumental in determining what information they have to work with and how they might make sense of and act upon that information. Unfortunately, many firms allow themselves to become under-connected, which isolates them from new sources of information, or over-reliant on just a few connections, creating a bottleneck for the flow of information. Herein, we describe how these problems manifest themselves among the network of interlocked directors, which is created when directors of firms sit on multiple boards. This network is so vast and complex that fully understanding the position and structure of a given firm's board interlocks remains elusive. Toward solving this problem, we offer five keys to developing a board with effective interlocks, as well as three cautions regarding how board interlocks could potentially hurt firms.
