How the provision of inflation information affects pension contributions: A field experiment

Ignoring the effects of inflation in retirement planning can have severe consequences for an individual's future financial well-being. Yet, many pension funds do not communicate inflation-related information, presumably for the fear of reduced contributions once the members understand how low the “real” return on saving for retirement is. As an alternative prediction, the provision of inflation information could increase pension contributions, because it reveals possible pension shortfalls. In cooperation with a major German pension fund, we conduct a field experiment, in which we vary the inflation information provided to the fund members, to explore this important issue. Among all participants, we find mostly positive but insignificant effects of the inflation information on pension contributions. Among those participants who voluntarily changed their pension contributions after the experimental intervention, the provision of inflation information significantly raises the likelihood of increasing pension contributions.     

A naturalistic approach to the theory of the firm: The role of cooperation and cultural evolution

One reason why firms exist, this paper argues, is because they are suitable organizations within which cooperative production systems based on human social predispositions can evolve. In addition, we show how an entrepreneur, given these predispositions, can shape human behavior within a firm. To illustrate these processes, we will present a model that depicts how the biased transmission of cultural contents via social learning processes within the firm influence employees’ behavior and the performance of the firm. These biases can be traced back to evolved social predispositions. Humans lived in tribal scale social systems based on significant amounts of intra- and even intergroup cooperation for tens if not a few hundred thousand years before the first complex societies arose. Firms rest upon the social psychology originally evolved for tribal life. We also relate our conclusions to empirical evidence on the performance and size of different kinds of organizations. Modern organizations have functions rather different from ancient tribes, leading to friction between our social predispositions and organization goals. Firms that manage to reduce this friction will tend to function better.     

To the Water’s Edge,and Beyond: Effects of Shore Protection Projects on Beach Development

The effects on real estate development of shore-protection efforts that lower erosion rates and storm hazards are both controversial and difficult to detect. A simple theoretical model indicates that shore protection is likely to tilt development from areas a few hundred feet inland toward beachfront property. A modified repeat-sale house price index is used to measure price appreciation rates to the waters edge. We are able to formulate an extremely sensitive empirical test for a tilt in rates of house-price appreciation implied by a tilt in development. Surprisingly, we find no significant evidence that shore-protection efforts have produced additional beachfront development in the Florida counties studied. The method used in this article is quite general and could be used in a number of applications where an environmental effect impacts real estate differentially over space.     

Toward a naturalistic foundation of the social contract

This paper delivers a step toward a naturalistic foundation of the social contract. While mainstream social contract theory is based on an original position model that is defined in an aprioristic way, we endogenize its key elements, i.e., develop them out of the individuals’ moral common sense. Therefore, the biological and social bases of moral intuitions are explored. In this context, a key adaptation during evolution was the one that enabled humans to understand conspecifics as intentional agents. Since these behavioral aspects are considered to be an exaptation, they are not amenable to direct genetic explanations or to rationality-based approaches.

A corporation’s culture as an impetus for spinoffs and a driving force of industry evolution

We offer a theory of spinoffs that explains some salient aspects of these important market entrants. In infant industries, a great share of new market opportunities is depleted by firms that spinoff from incumbents. A model emphasizing the relation between incumbents’ evolving corporate cultures and the generation of spinoffs explains this regularity in industry evolution. By doing so, we capture different patterns in firm development that finally will help explain the evolutionary paths that industries may follow. We show that organizations reach a critical size that entails the collapse of a cooperative culture and triggers the exodus of personnel founding own firms. Thereby, organizations with a cooperative culture active in a dynamic business environment provide ideal training grounds for potential founders. Moreover, we argue that cooperative firm cultures and processes of “entrepreneurial imprinting” are important sources of spinoffs’ superior capabilities concerning their later market performance. We relate our findings to empirical evidence on developmental patterns in industries, such as genealogies and performance of spinoffs.     

The Human Adaptation for Culture and its Behavioral Implications

During phylogeny, man adapted for culture in ways other primates did not. This key adaptation is the one that enabled humans to understand other individuals as intentional agents like the self. This genetic event opened the way for new and powerful cultural processes but did not specify the detailed outcomes of behavior we see today. It just provided the basis for cultural evolution that, with no further genetic events, enabled the distinctive characteristics of human cognition. These capabilities can explain the motivational underpinnings of a variety of human inclinations and behaviors, such as a tendency toward cooperation, altruism, or fairness.

Long-term tendencies in technological creativity - a preference-based approach

Given the significance of technology in the course of socio-economic evolution, the driving forces behind the continuous accretion of technological knowledge deserve particular attention. This paper suggests a hypothesis about the motivational underpinnings of human technological creativity that is able to explain some long-term developments in human labor and technology. These motivational underpinnings are considered to being similar across human beings. They can therefore be assumed to imply some commonly shared elements of human preferences or wants.JEL Classification: B52, J24, N30, O31, O33The author is indebted to colleagues at the Friedrich Schiller University and the Max Planck Institute in Jena, Luciano Andreozzi, Leonard Dudley, Marco Lehmann-Waffenschmidt, and an anonymous referee of this journal for helpful comments.
