Max Planck Institute of Economics
Jena, Germany

The Max Planck Institute of Economics was founded in 1993 as the Max Planck Institute for Research into Economic Systems . Its initial mission was researching the transition of the former Eastern European socialist economic systems, but it now researches a broad set of problems relating to change in modern economies more generally, including evolutionary economics, experimental economics, and entrepreneurial studies. The institute is one of 80+ research institutes of the Max Planck Society and is located in Jena.It is organized into three research units: Evolutionary Economics Group , Strategic Interaction Group Entrepreneurship, Growth and Public Policy Group . The institute is located in the Kahlaische Strasse, about 1 km south-east of the city centre. It is housed in an attractively restored Victorian villa, linked by a glass bridge to a much larger modern building, which includes offices and other facilities for each of the research units, each unit having one floor of the main section of the building. In addition the new buildings include a substantial library, and apartments where visitors to the institute can be accommodated. Wikipedia.

Previous research suggests that children develop an increasing concern with fairness over the course of development. Research with adults suggests that the concern with fairness has at least 2 distinct components: a desire to be fair and a desire to signal to others that they are fair. We explore whether children's developing concern with behaving fairly toward others may in part reflect a developing concern with appearing fair to others. In Experiments 1 and 2, most 6- to 8-year-old children behaved fairly toward others when an experimenter was aware of their choices; fewer children opted to behave fairly, however, when they could be unfair to others yet appear fair to the experimenter. In Experiment 3, we explored the development of this concern with appearing fair by using a wider age range (6- to 11-year-olds) and a different method. In this experiment, children chose how to assign a good or bad prize to themselves and another participant by either unilaterally deciding who would get each prize or using a fair procedure-flipping a coin in private. Older children were much more likely to flip the coin than younger children, yet were just as likely as younger children to assign themselves the good prize by reporting winning the coin flip more than chance would dictate. Overall, the results of these experiments suggest that as children grow older they become increasingly concerned with appearing fair to others, which may explain some of their increased tendency to behave fairly.© 2013 American Psychological Association.

FRITSCH M. and SLAVTCHEV V. Determinants of the efficiency of regional innovation systems, Regional Studies. This paper analyses differences in the efficiency of regional innovation systems. Alternative measures for the efficiency of regional innovation systems based on the concept of a knowledge production function are discussed. The empirical findings suggest that spillovers from within the private sector as well as from universities and other public research institutions have a positive effect on the efficiency of private sector research and development. It is particularly the intensity of interactions between private and public sector research and development that increases the efficiency. It is found that regions dominated by large establishments tend to be less efficient than regions with a lower average establishment size. © 2011 Regional Studies Association.

Using a choice experiment, this paper investigates how Swedish citizens value three environmental quality objectives. In addition, a follow-up question is used to investigate whether respondents ignored any attributes when responding. The resulting information is used in model estimation by restricting the individual parameters for the ignored attributes to zero. When taking the shares of respondents who took both the environmental and the cost attributes (52-69% of the respondents) into account, then the WTP for each attribute changes if the respondents who ignored the attributes have a zero WTP. At the same time, we find evidence that not all respondents who claimed to have ignored an attribute really did. However, the most commonly ignored non-monetary attributes always have the lowest rankings in terms of WTP across all three environmental objectives. Thus, our results show that instead of ignoring attributes completely, respondents seem to put less weight on the attributes they claimed to have ignored. © 2010 Springer Science+Business Media B.V.

Strong growth in disposable income has driven, and is still driving, consumption to unprecedented, but not sustainable levels. To explain the dynamic interplay of needs, need satisfaction, and innovation underlying that growth a behavioral theory of consumption is suggested and discussed with respect to its implications for making a transition to more sustainable patterns of consumer behavior. © 2011 Elsevier B.V.

This paper presents a formal model in which differential satiation dynamics of various consumer needs explain (not only describe) the shapes of Engel curves. In the model, individuals allocate their income to various consumption categories proportional to corresponding need deprivation states, a decision making process called matching. The model allows explaining some empirical regularities that other models have difficulties accounting for. It can, for example, reconstruct that income elasticities for food tend to decrease with rising income, and that goods that are luxuries at relatively low income levels can become necessities at higher income levels. Moreover, the paper compares the Engel curves obtained from the matching model with Engel curves obtained from a utility maximization model. While both types of Engel curves are relatively similar at high income levels, at lower income levels matching and maximization lead to very different allocations of income. The paper shows that a given amount of income redistribution leads to less additional welfare when individuals follow matching behavior than when they maximize their utility. Accordingly, to obtain a given amount of additional welfare more income redistribution is needed than a policy maker who (mistakenly) assumes that individuals rationally maximize their utility predicts. © 2013 Springer-Verlag Berlin Heidelberg.

The present crisis is a financial crisis only at the surface. In actual truth there is a much more consequential growth crisis behind it. This "view point" discusses why this is so and what consequences follow from this diagnosis when seeking for remedies for the crisis. Particular attention is given in the discussion to the fact that the crisis occurs just at a time when the necessity to cope with the climate change is getting ever more pressing. © 2012 Elsevier B.V.

If resource consumption is to be reduced through economic "de-growth", individuals in industrialized countries may have to accept a reduction in their consumption levels. In democratic societies, implementing this process requires the consent of a majority of the population. However, as long as people have high reference levels of consumption, lower consumption will induce feelings of loss, and hence evoke resistance. This paper summarizes recent experimental evidence on some of the factors that determine the utility costs involved in decreasing consumption. The results suggest that the acceptance of economic de-growth would be facilitated if people's material aspirations were moderated, and the extent to which material achievements are emphasized in our daily environment were reduced. An analysis of the financial and economic crisis that developed during 2008 suggests that it will not contribute to either of these points. Rather, by increasing the public's focus on the economic sphere even beyond pre-crisis levels, it may lead to a further decrease in the acceptance of de-growth policies in the population. © 2009 Elsevier Ltd.

The rapidly growing literature on the relationship between energy consumption and economic growth has not univocally identified the causal relationship yet. We argue that bivariate models, which analyze the causality only at the macro level, are eventually misleading, especially in cases where both variables do not cover the same scope of economic activity. After discussing appropriate pairs of variables, we investigate Granger causality between energy and growth in the U.S. for the period from 1970 to 2007 for three sectors, industry, commercial sector, transport, as well as on the macro level. Using the recently developed ARDL bounds testing approach by Pesaran and Shin (1999) and Pesaran et al. (2001), we find evidence for unidirectional long-run Granger causality in the commercial sector from growth to energy, as well as evidence for bi-directional long-run Granger causality in the transport sector. The dependence of causality on the level of aggregation is interpreted as evidence for 'Simpsons' Paradox'. The choice of control variables is based on findings from the Environmental Kuznets Curve literature: we find that controlling for the increasing energy productivity of production as well as trade significantly improves the fit of the bivariate model. © 2011 Elsevier B.V.

In Germany, solar thermal systems (STSy) have only diffused to a minor extent as yet. This paper analyzes which demand side factors are decisive for the further proliferation of this environmentally benign technology. Making use of a consumer survey in northwestern Germany in 2007, we examine the following parameters: positive environmental attitude, knowledge of the applicability of STSy to satisfy consumer needs, and the presence of STSy among peer consumers. Drawing upon theoretical foundations from innovation economics and social psychology, we posit that these variables play a different role at distinct stages of the systems' diffusion process. Among nonowners, concrete plans to purchase such a system within the next two years are distinguished from the general interest to invest in this technology within the next five years. Probit models are estimated to test our hypotheses. Our results do not indicate a strong take-off of product diffusion within the next few years. By generating interest for the product, environmental attitude and knowledge as well as household income are important determinants of prospective adoption on the part of nonowners. However, it is only peer group behavior that appears to function as a trigger for the diffusion of this technology. © 2011 Elsevier B.V.

In this work the exceptional field theory formulation of supergravity with SL (5) gauge group is considered. This group appears as a U-duality group of D = 7 maximal supergravity. In the formalism presented the hidden global duality group is promoted into a gauge group of a theory in dimensions 7+number of extended directions. This work is a continuation of the series of works for E8,7,6, SO (5, 5) and SL (3) × SL (2) duality groups. © 2016, The Author(s).
