The microeconomics courses are based on the textbooks “Microeconomic Theory” by MasColell et al. (1995) and “Advanced Microeconomic Theory” by Jehle and Reny (2011). The
“Discrete Mathematical Finance” course is based on “Introduction to Mathematical Finance:
Discrete Time Models” by Pliska (1997). The other courses are based on different books and

A Measure of Instability for Matchings in Marriage Markets
This article was awarded the Jacques Nass Prize for Excellence in Political Economy Research
of the Hebrew University (endowed with NIS 40000 / approx. $12000).
Abstract: In marriage markets (two-sided one-to-one matching problems) the number of
blocking pairs which exist against a matching is often used as a measure of instability. We
argue that in many cases this measure is economically implausible. To fix the problem, we
state two axioms which should be fulfilled by sets of blocking pairs whose cardinalities are
taken as measures of instability. We offer economic interpretations both of these axioms
and of the corresponding sets. Furthermore, we show how to compute these sets and prove
some properties which are relevant for a workable measure of instability.
Task Assignment with Autonomous and Controlled Agents (joint work with Victor
Naroditskiy, Maria Polukarov, Alex Rogers, Nicholas R. Jennings) – Mathematical Social
Sciences 71, 2014, Pages 116-121
Abstract: We analyse assignment problems in which not all agents are controlled by the
central planner. The autonomous agents search for vacant tasks guided by their own
preference orders defined over subsets of the available tasks. The goal of the central planner
is to maximise the total value of the assignment, taking into account the behaviour of the
uncontrolled agents. This setting can be found in numerous real-world situations, ranging
from organisational economics to "crowdsourcing" and disaster response. We introduce the
Disjunctively Constrained Knapsack Game and show that its unique Nash equilibrium reveals
the optimal assignment for the controlled agents. This result allows us to find the solution of
the problem using mathematical programming techniques.
The Deployment of Conditional Probability Distributions for Death Time Estimation (joint
work with S. Potente) – Forensic Science International, Volume 210, Issues 1-3, 2011, Pages
82-86
Abstract: The temperature based algorithm known as the Nomogram Method for the
determination of a 95.45% death-time interval can be combined with non-temperature
based (NTB) findings in the so called Compound Method (CM). The impact of such
integration on the probability yielded by the resulting interval has however neither been
described nor exploited. In fact the interval after integration of NTB findings rarely yields
95.45% probability. We present a technique, based on the conditional probability
distribution that can be calculated if the NTB findings are taken into account, which ensures
the probability inside the interval to be 95.45%. The technique was successfully applied to a
set of 53 cases published by Henssge et al. (2000) and led to a reduction of the interval width
up to more than 15% compared to the CM interval, whereas in other cases the interval
length increased in width due to probability content of the CM intervals below 95.45%. A
spreadsheet file in which the method proposed in this paper is implemented can be
obtained upon email request from the author S. Potente.
The Organizational Matching Game
Abstract: In an organization, an employee who loses his function ususally does not get fired
right away but instead is granted a time window to find another position within the
organization. This paper explores strategic issues which are relevant for the employee in that
situation. If the worker's successful application for a new position sets free another
employee, a sequence of job-changes of different players may be the consequence. This
dynamic is modeled here as an extensive form game with matching theory in the
background. The game is proved to have a unique subgame perfect equilibrium which can be
characterized by the property that every employee moves at most one time, a result which
allows for an economic interpretation.
