Goals of Action and Emotional Reasons for Action. A Modern Version of the Theory of Ultimate Psychological Hedonism

In this paper we present a modern version of the classic theory of “ultimate psychological hedonism” (UPH). As does the UPH, our two‐dimensional model of metatelic orientations also postulates a fundamentally hedonistic motivation for any human action. However, it makes a distinction between “telic” or content‐based goals of actions and “metatelic” or emotional reasons for actions. In our view, only the emotional reasons for action, but not the goals of action, conform to the UPH. After outlining our model, we will elucidate the similarities and differences between our model and classic UPH. In this context we will clarify several basic misconceptions regarding classic UPH. In a next step, two major criticisms of the theory of ultimate psychological hedonism will be discussed, that is (1) the statement that the hedonistic principle has no motivating effect at all and (2) the argument that the hedonistic motivation is only one of many motivations of human actions. We believe that both of these arguments can be refuted. Finally, we will discuss the compatibility of our model with evolutionary theory.     

Estimating Archimedean Copulas in High Dimensions

Abstract. This article presents a novel estimation procedure for high‐dimensional Archimedean copulas. In contrast to maximum likelihood estimation, the method presented here does not require derivatives of the Archimedean generator. This is computationally advantageous for high‐dimensional Archimedean copulas in which higher‐order derivatives are needed but are often difficult to obtain. Our procedure is based on a parameter‐dependent transformation of the underlying random variables to a one‐dimensional distribution where a minimum‐distance method is applied. We show strong consistency of the resulting minimum‐distance estimators to the case of known margins as well as to the case of unknown margins when pseudo‐observations are used. Moreover, we conduct a simulation comparing the performance of the proposed estimation procedure with the well‐known maximum likelihood approach according to bias and standard deviation.     

Understanding the position of end nodes in the world city network: using peer city analysis to differentiate between non‐hub cities

In the current debate on the world city network and inter‐city connectivity, a large number of cities, particularly in developing countries, have received limited attention. Despite a growing interest in emerging market cities, many scholars still focus on the more affluent parts of the global economy. In an attempt to redress this imbalance, I present an assessment for use on cities that are not at the centre of the network; but what we consider ‘end nodes’. I build my argument on Taylor's interlocking model for assessing city connectivity and zoom in on the types of networks that non‐hub cities create through their inter‐linkages with so‐called peer cities in the same economic sector. I take these ego networks as a starting point and then lead the argument on to view city networks from a non‐hub perspective. This allows me to identify the existing linkages between different peer cities within as well as between selected city networks. The renewable energy business in India puts this argument to an empirical test. My findings confirm that this way of looking at city connectivity allows one to assess specifically for city end nodes and thereby contribute to a more nuanced understanding of the world city network.     

Remapping social inequalities in an age of climate change: for a cosmopolitan renewal of sociology*

Climate change globalizes and radicalizes social inequality; it exacerbates inequalities of rich and poor, core and periphery, and at the same time dissolves them in the face of a common threat to humanity. Climate change combines with the inequalities arising from globalization, decoupling the producers and subjects of risk. Remapping inequality in the age of climate change and globalization therefore requires taking account of the unbounding of both equality and inequality, and an awareness of the end of the opposition between society and nature, one of the founding principles of sociology. The article outlines four theses of inequality, climate change and globalization, and concludes with the question: what does a cosmopolitan renewal of the social sciences mean and how will it be possible?     

Non-parametric Estimation of Tail Dependence

Abstract.  Dependencies between extreme events (extremal dependencies) are attracting an increasing attention in modern risk management. In practice, the concept of tail dependence represents the current standard to describe the amount of extremal dependence. In theory, multi-variate extreme-value theory turns out to be the natural choice to model the latter dependencies. The present paper embeds tail dependence into the concept of tail copulae which describes the dependence structure in the tail of multivariate distributions but works more generally. Various non-parametric estimators for tail copulae and tail dependence are discussed, and weak convergence, asymptotic normality, and strong consistency of these estimators are shown by means of a functional delta method. Further, weak convergence of a general upper-order rank-statistics for extreme events is investigated and the relationship to tail dependence is provided. A simulation study compares the introduced estimators and two financial data sets were analysed by our methods.     

Cosmopolitan communities of climate risk: conceptual and empirical suggestions for a new research agenda

Mitigating human‐induced climate change calls for a globalized change of consciousness and practice. These global challenges also demand a double transformation of the social sciences – first, from ‘methodological nationalism’ to ‘methodological cosmopolitanism’ and, second, an empirical reorientation towards ‘cosmopolitization’ as the social force of emerging cosmopolitan realities. One of these realities is the possible emergence, locally and globally, of ‘cosmopolitan communities of climate risk’ in response to a ‘world at risk’. A key research question for contemporary social science is thus: how and where are new cosmopolitan communities of climate risk being imagined and realized? In this article, we propose and explore a research agenda formulated around this key question. We both develop a theoretical perspective and provide short empirical illustrations of case studies regarding ongoing research in Europe and East Asia on such cosmopolitan climate risk communities.
