The "common effect" model in program evaluation assumes that all treated individuals have the same impact from a program. Our paper contributes to the recent literature that tests and goes beyond the common effect model by investigating impact heterogeneity using data from the experimental...

This study provides a basic introduction to agent-based modeling (ABM) as apowerful blend of classical and constructive mathematics, with a primary focus onits applicability for social science research. The typical goals of ABM social scienceresearchers are discussed along with the culture-dish...

Finanzmathematische und demographische Methoden werden präsentiert, um den Einfluß von Wanderungen auf die langfristige Bevölkerungsentwicklung zu präsentieren. Finanzmathematische Methoden berücksichtigen nicht die Altersstruktur einer Bevölkerung und können daher nur als Approximation...

Longevity risk has become a major challenge for governments, individuals, and annuity providers in most countries, and especially its aggregate form, i.e. the risk of unsystematic changes to general mortality patterns, bears a large potential for accumulative losses for insurers. As obvious risk...

This volume is a monograph on the geometric structure of a certain class of ("comprehensive") compact polyhedra called Cephoids. A Cephoid is a Minkowski sum of finitely many standardized simplices. The emphasis rests on the Pareto surface of Cephoids which consists of certain translates of...

This book is devoted to the application of fractional calculus in economics to describe processes with memory and non-locality. Fractional calculus is a branch of mathematics that studies the properties of differential and integral operators that are characterized by real or complex orders....

Matrices, their products, linear systems, and the underlying geometric ideas are presented in an intuitive and practical way for economics students and other students of the social sciences. Python Jupyter notebooks are used to present examples that enforce the geometric ideas
