Kairos economies in the post-Soviet transition period of Central Asia

There are times when entire populations of certain countries have had to readjust their lives and economic strategies as all of society is under transition. Post-Soviet Central Asia underwent this period after 1991. During times of transition, there are always people that tend to be able to make use of the new uncertainties, even at the risk of entering legal grey areas. Here new social groups emerge, ethnic origin becomes relevant and new kinship ties are made. These transformation periods are often short and provide limited opportunities for analysing the strategies of those pioneers that I call Kairos economists. They often act only in cooperation with residents of the border and with duty customs and security personnel. This article analyses this special economy with the help of case studies that have been observed during the transformation period from the Soviet to an independent Central Asia.     

Allais for the poor: Relations to ability,information processing,and risk attitudes

This paper complements evidence on the Allais paradox from advanced countries and educated people by a novel investigation in a poor rural area. The share of Allais-type behavior is indeed high and related to indicators of “lacking ability,” such as poor education, unemployment, and little financial sophistication. Based on prospective reference theory, we extend these characteristics by biased processing of probabilistic information. Finally, we reveal that Allais-type behavior is linked to risk-related characteristics, such as risk tolerance and optimism. This indicates a potential problem as exactly the more dynamic among the poor tend to make inconsistent decisions under uncertainty.     

Parameter estimation in nonlinear regression models 1

Fisher information contained in record values, inter-record times and their concomitants from a sample of fixed size is derived in general and explicit expressions are deduced for some specific known bivariate classes of distributions. A comparison between fixed sampling and inverse sampling schemes with equal number of records and concomitants is also carried out. We also consider parameter estimation based on bivariate records and a small simulation study is done.     

Armut und Klassenstruktur

The article tries to combine dynamic and multidimensional poverty-research with class analysis, using data from the German Socio-Economical Panel. A multidimensional indicator for measuring poverty both long-term and cross-sectional is developed, based on theoretical assumptions concerning the relations between poverty, time and social inequality. The empirical results of this approach give no evidence neither of temporalization of poverty nor of a new social cleavage between exclusion and inclusion. Instead they depict almost time-stable stratas or zones of high poverty, precarity and wealth, which are closely related to social class. Estimating binary logistic regressions, the effect of social class on poverty-risks remains highly significant controlling for several socio-demographic variables and even labour-market issues such as unemployment. In the core of new poverty, it is pointed out, we can still find working class families.

Activation,Public Employment Services and their Clients: The Role of Social Class in a Continental Welfare State

This article fills a gap in the existing literature by investigating how public employment service (PES) staff actually deal with their clients under a continental regime of activation. The results reported here are based on interviews both with PES staff and their unemployed clients in Germany. We argue that due to its Bismarckian origins as an insurance‐based system of ‘unemployment protection’, Germany's system of unemployment compensation is attractive not only for the marginalized, but also for core workers. As a result, PES staff deal with clients from very heterogeneous class backgrounds. We demonstrate that social class is a significant factor in client outcomes, and that earlier research has perhaps overemphasized the role of frontline staff as ‘street‐level bureaucrats’. While staff do have considerable power, the result of the encounters between the administration and clients also depends on the capabilities of the clients, which, in turn, are strongly related to social class.     

Diesseits von Coaching und Mentoring: Kollegiale Praxisberatung

Zusammenfassung  Die Methode der kollegialen Beratung eignet sich gut für Menschen in Organisationen, die vor der Herausforderung stehen, ihr Prozesswissen in neuen, unbekannten Kontexten anzuwenden. Schnelligkeit und konkreter Praxisbezug sind dabei wesentliche Faktoren für eine akzeptierte Lernform. In diesem Artikel wird eine Anpassung der Grundmethode der kollegialen Beratung, die kollegiale Praxisberatung, vorgestellt, die diese Anforderung der Praktiker erfüllt. Die dabei auftretenden Prozesswirkungen und Lernerfahrungen werden anhand zweier Praxisbeispiele aus der Industrie illustriert und Chancen sowie Grenzen der Methode diskutiert.
