The research team is investigating the competitiveness of domestic and international micro, small and medium-sized enterprises (MSMEs) using a self-developed questionnaire. The competences of MSMEs are measured along ten dimensions. The methodology and data set are suitable for identifying the unique strengths and weaknesses of small firms based on their competencies. The dataset can be complemented with a set of competitiveness indices and rankings combined with regional and institutional factors, which can be used as a basis for businesss and economic policy recommendations.

Generating data through questionnaire surveys and laboratory experiments, the research group investigates the personality traits and cognitive processes associated with market entry decisions, entrepreneurial success, and innovation. This line of research is mainly focused on questions related to entrepreneurial overconfidence, optimism, effectuation and alertness. The other key research line of the group concentrates on the personal characteristics behind particular financial behaviours and well-being. For instance, we study what information influences the choice of brokers to follow on social trading platforms and under what conditions herding occurs in stock markets.

Using methods in economic modelling, the group studies the resilience and adjustment capability of production and market systems, their reaction to different shocks, and the spread of these shocks at different levels of the economy. There is special emphasis on questions related to the structural aspects of supply and production networks, how different characteristics of economic structure are associated with the spread of and adjustment to shocks. The group develops and applies the GMR economic impact modell which is suited for simulating the potential effects of alternative technologies and the reconstruction of production systems and networks.

ESG (environmental, social and governance) factors are receiving increasing attention in the financial sector, as more and more investors and companies consider them important. The international and domestic research carried out by our research team will allow us to measure the impact of ESG pillars from different perspectives and make recommendations to companies based on the results. Our questionnaire-based domestic study is a particularly important element of the research, as SMEs are present in large numbers in the Hungarian economy and taking ESG aspects into account gives them the opportunity to become more competitive and better adapted to the changing market environment. The methods and tools used in the data collection and analysis allow for a broad assessment of the ESG performance of companies, and the results of the research will allow us to develop our own index and ranking, which will provide companies with concrete recommendations to improve their performance. The results of the research will be of interest not only to market participants, but also to various decision-makers (e.g. investors, government), as they will provide an opportunity to make more responsible decisions by taking ESG aspects into account.

The research group is dedicated to identifying pivotal factors crucial for the development of the domestic industry. Our approach encompasses a global perspective, delving into the roles of multinational companies, the absorptive capacity of domestic entities, and the quality of connections between these segments. Special attention is given to the analysis of global value chains, (re-) location strategies and the inherent learning effects within them. This includes a thorough exploration of the dynamic optimization of production capability locations. Within our quality-focused models, we also explore dynamic pricing inquiries and examine the impact of quality-optimized inventory management on shaping production performance.
