Lorenz curves and associated tools for ranking income distributions are commonly estimated on the assumption that full, unbiased samples are available. However it is common to ¯nd income and wealth distributions that are routinely censored or trimmed. We derive the sampling distribution for a key family of statistics in the case where data have been modified in this fashion.

In diesem Aufsatz werden Methoden zur Identifikation kausaler Effekte von staatlichen Eingriffen am Beispiel von Fortbildungs- und Umschulungsprogrammen vorgestellt und deren Implikationen und Voraussetzungen diskutiert. Desweiteren werden Eigenschaften jeweils in Frage kommender Schätzmethoden erörtert. Dadurch soll dieser Aufsatz eine Hilfestellung bei der Auswahl einer für das...

This article seeks to explain differential participation in social movements. People are not brought to collective action at the same level of intensity. Some become core activists, while others invest only little time and effort. We test a number of hypotheses drawn from the social networks and the rationalist perspectives on individual engagement by means of survey data on...

Social movements can have an impact on institutions by aiming explicitly at institutional change or by pursuing policy goals. In the former situation, their chances of success depends on factors internal and external to the movements. In the latter situation, the contribution of policy-oriented movements to institutional reform can be seen as a by-product of their action. A process...

We analyse the stability properties of mixed equilibria in 2×2 asymmetric games under evolutionary dynamics. With the standard replicator dynamics these equilibria are stable but not asymptotically stable. We modified the replicator dynamics by introducing players of two types: myopies — like in the standard replicator dynamics — and best
responders. The behaviour of the latter...

The paper presents an empirical analysis of a model of endogenous growth and innovation with unequal incomes and hierarchical consumer demand. The theoretical model predicts a positive impact of income inequality on product diversity. The impact of inequality on per-capita growth may be positive or negative depending upon the assumptions about productivity growth, where the standard...

A bank's financial management faces various sources of uncertainty when funds from savings account deposits are invested in the marketplace. Future interest rates are unknown and customers are allowed to withdraw their deposits at any point in time. The objective is to find a portfolio of fixed income instruments that maximizes the bank's interest surplus from the...
