2014 - 2015, Játékelméleti Kutatócsoport
Form of participation: member of the research team
Moneylender: Magyar Tudományos Akadémia
Further info about research: The research group supported by the Momentum Programme of the Hungarian Academy of Sciences aimed at understanding, modeling and solving certain problems within the realm of game theory. The focus of research was at cooperative games, where the players interactions generate externalities, that is, third parties, not directly participating in the activities may get affected. In partition function form games the third party is a third player or another coalition, while in dynamic cooperative games it may well be the future self of one of the acting agents. Besides the theoretical results, the aim was also to apply them in economic models, of these, the applications of power indices and matching models were especially prominent in the research profile.
2012 - 2012, Network analysis of the Hungarian interbank deposit market
Form of participation: leader of the research team
Moneylender: Magyar Nemzeti Bank
Further info about research: Networks change in time and changes in the network topology may characterize and forecast liquidity crises. We examined the Hungarian interbank deposit market between 2003 and 2012 and investigated the behavior of the players, flows of funding, and the corresponding graph measures. These results can be used as inputs of an “early warning system” and also may help to detect systematically important players.
2011 - 2011, Modeling market microstructure with interacting agents
Form of participation: leader of the research team
Moneylender: Morgan Stanley
Further info about research: The objective of the research project was to investigate a market with interacting agents with a focus ona) the effect of heterogeneous information patterns and beliefs on liquidity, b) the effect of heterogeneous agents hedging their underlying position in a multi-asset market environment on market prices and liquidity.
2011 - 2011, Order execution strategies – How traders do it?
Form of participation: leader of the research team
Moneylender: MSCI
Further info about research: Market players have some ideas about market liquidity tendencies. Based on this, they develop effective order-splitting and timing strategies. In this research project, we performed interviews with different types of traders and investigated how they tried to optimize their trading in practice (typical situations, rules of thumb etc.).

Moneylender: European Commission Directorate-General for Education and Culture
Further info about research: The general purpose of the project was to make lifelong learning and mobility a reality, by reducing financial barriers. The main tasks were:- description and evaluation of present practices- evaluating the Community Added Value (CAV)- creating a new pan-European institution (Erasmus+)
2010 - 2010, N° AO/RPA/PLI-PSZO/Loans/016/09 “The Role of Loans in Financing Vocational Education and Training in Europe”
Form of participation: leader of the research team
Moneylender: CEDEFOP

2006 - 2007, Future of Higher Education in Europe, International Comparative Analysis
Form of participation: leader of the research team
Moneylender: British Council
Further info about research: Discussion forums and workshops amongst several teams of European countries. Teams were participating in an international think thank workshop series to determine future strategies and scenarios for the European Higher Education in everyone’s own country. The program was finished with a conference and a book summarizing the findings and conclusions.
2005 - 2007, Complex Systems,
Form of participation: member of the research team
Moneylender: Collegium Budapest, NAP Project
Further info about research: COLBUD was a multidisciplinary research institute with the participation of highly respected and known scholars from worldwide. NAP Project was a European Funded mega-project. I was a Senior Research Fellow responsible for the “Risk-Management of a special credit portfolio” project team. We analyzed data on the repayment of the Hungarian student loan system, carried out simulations, designed optimal stochastic control systems to ensure the stability of the system and advised decision makers for the best interventions.
2004 - 2006, Sztochasztikus Rendszerek és Pénzügyi Piacok Modellezése
Form of participation: member of the research team
Moneylender: OTKA 047193
Further info about research: The objective of this research was to apply and develop advanced methods of stochastic systems for modeling financial markets. A current challenge in financial mathematics is the development of reliable hedging strategies for incomplete markets. Mathematically, this is a stochastic adaptive control problem in which the dynamics of the system is described by a multivariable switching diffusion process. This major problem could be related to a number of simpler problems. Most of our research topics were related to technical problems that could be handled within the framework of a Ph.D. program. The main areas were: hidden Markov models, models for a stock exchange, stochastic volatility and the relationship between stochastic control and option pricing. In addition, we have studied a few fundamental problems of stochastic adaptive control.
2004 - 2005, Nyugdíjrendszer és diákhitel-rendszer összekapcsolása
Form of participation: leader of the research team
Moneylender: OM, Deák Ferenc kutatóösztöndíj
Further info about research: The objective of the fellowship was to explore how the student loan and pension systems can be interconnected to exploit their synergies. It resulted in a study titled “Joint Model of Pension and Student Loan” in which I worked out and recommended the introduction of a new pension model.
