This book studies the sustainability and optimality of public debt under different scenarios: the closed economy, the small open economy, and a two-country setting. Sustainability refers to the existence and the stability of the long-run equilibrium. Optimality relates to the path of public debt that maximizes discounted utility. The analysis is conducted within the framework of the Solow model, the overlapping generations model and the infinite horizon model. The government can follow different strategies, it either fixes the deficit ratio or the tax rate. As a result, a fixed deficit ratio generally can be sustained. By contrast, a fixed tax rate generally cannot be sustained. Depending on the chosen fiscal strategy, there exists either an optimal deficit ratio or an optimal tax rate that maximizes the sum of consumption and government purchases per capita.

The connection of economic theory and behavior is one of the central topics of this book - and also a central issue in economic thinking of Horst Todt to whom this book is dedicated. The contributions deal with topics of normative and descriptive decision-making: They investigate, for instance, the emergence of decisions or the role of imitation as a competitive principle. A number of contributions treat special decision-making problems on a micro or on a macro level, whereas others concentrate on the principle questions of decision-making or on the conceptualization of important but fuzzy notions like power or solidarity

Abstract
Some historical aspects on late lessons from early warnings on cancer risks with lost time for prevention are discussed. One current example is the cancer-causing effect from radiofrequency (RF) radiation. Studies since decades have shown increased human cancer risk. The fifth generation, 5G, for wireless communication is about to be implemented world-wide despite no comprehensive investigations of potential risks to human health and the environment. This has created debate on this technology among concerned people in many countries. In an appeal to EU in September 2017, currently endorsed by more than 400 scientists and medical doctors, a moratorium on the 5G deployment was required until proper scientific evaluation of negative consequences has been made (www.5Gappeal.eu). That request has not been taken seriously by EU. Lack of proper unbiased risk evaluation of the 5G technology makes adverse effects impossible to be foreseen. This disregard is exemplified by the recent report from the International Commission on non-ionizing radiation protection (ICNIRP) whereby only thermal (heating) effects from RF radiation are acknowledged despite a large number of reported non-thermal effects. Thus, no health effects are acknowledged by ICNIRP for non-thermal RF electromagnetic fields in the range of 100 kHz–300 GHz. Based on results in three case-control studies on use of wireless phones we present preventable fraction for brain tumors. Numbers of brain tumors of not defined type were found to increase in Sweden, especially in the age group 20–39 years in both genders, based on the Swedish Inpatient Register. This may be caused by the high prevalence of wireless phone use among children and in adolescence taking a reasonable latency period and the higher vulnerability to RF radiation among young persons.
