Manfred Paier Title: Exploring Regional Twin Transition Pathways with an Empirical Agent-Based Model Abstract: The twin transition—an integrated approach to digitalization and green innovation—is central to the European Union’s strategy for addressing climate change while fostering economic competitiveness. However, European regions exhibit significant heterogeneity in innovation capacities, industry structures, and institutional frameworks, affecting their ability to navigate this transition effectively. This ongoing project explores regional twin transition pathways by analysing the transformation of technological knowledge bases using an empirical agent-based model (ABM). We employ an ABM that simulates knowledge creation processes in 292 NUTS2 regions across Europe. The model represents 70,000 heterogeneous agents, characterized by sectoral affiliations, R&D intensities, and technological endowments, and specifies agent interactions for learning and knowledge exchange. It examines the mechanisms through which regions advance toward green and digital specialization, identifying pathways such as related and unrelated diversification, upgrading, and importation. By incorporating spatial microsimulation techniques and patent data from 2015–2020, we quantify regional specializations in green and digital technologies, allowing us to assess the impact of pre-existing capabilities on transition trajectories. First results indicate that regions with established green and digital knowledge bases predominantly follow related diversification, reinforcing existing expertise. Conversely, less technologically advanced regions rely on importation and unrelated diversification, facing greater structural challenges in transitioning toward twin specialization. Spatial spillover effects further influence transition dynamics, with advanced regions in Germany, Scandinavia, and Southern France leading the twin transition, while Eastern and South-Eastern European regions exhibit lagging trends. These findings highlight the evolutionary nature of technological transitions and the role of regional characteristics in shaping twin transition pathways. Future research will extend the model to assess policy interventions fostering interregional collaboration and diversification, providing insights for targeted innovation strategies. | ||

Sándor Juhász Title: Colocation of skill related suppliers -- Revisiting coagglomeration using firm-to-firm network data Abstract: Firms in industry clusters benefit from locating close to their suppliers and customers. However, emerging global supply chains question the need for colocation to manage buyer-supplier relationships. We hypothesize that supply chain partners are more likely to colocate if they exchange not only goods but also know-how. Building on the literature of coagglomeration and using micro-data on the Hungarian economy, we study colocation, labor flows and value chain connections at the level of firms and pairs of industries. We show that supply chains are more likely to support colocation when the firms involved operate in skill related industries. | ||

Juhász Sándor Cím: Cégek beszállítói hálózatai magyar adatokon keresztül Absztrakt: Magyarország azon kevés ország egyike, ahol a cégek ÁFA bevallásaiból származó adatok elérhetőek kutatási célokra. Ezek az adatok lehetővé teszik a beszállítói hálózatok vállalati szintű tanulmányozását a nemzetgazdaság egészében. Ez az előadás áttekintést nyújt ezekről az adatokról és felvillant néhány lehetőséget, amely az ÁFA adatok más adatbázisokkal való kombinálásából adódik a cégek, iparágak és régiók gazdasági kapcsolatainak tanulmányozására. | ||

Dr. Váry Miklós Előadás témája: Volt-e fiskális ingyen ebéd Magyarországon 1999-2019 között?. Absztrakt: Az előadás azt vizsgálja, hogy voltak-e olyan időszakok 1999 és 2019 között Magyarországon, amelyek során önfinanszírozó volt a kormányzati költekezés. Ez egy olyan állapotot jelent, amikor a költségvetési deficit növekedése nem vezet a GDP-arányos államadósság növekedéséhez, mivel a deficit élénkíti a gazdasági teljesítményt is. Egy egyszerű adósságdinamikai modell paramétereinek becslésére kerül sor magyar adatokon, majd azt vizsgálja az előadás, hogy érvényes-e az előbbi érvelés egy feltörekvő, kis nyitott gazdaságra is, amilyen a magyar.

Philipp Koch, Researcher, EcoAustria - Institute for Economic Research, Vienna, Austria Title: From better understanding economic history through machine learning to shedding light on emissions and value-added in global value chains Abstract: Quadrupling historical GDP per capita estimates through machine learning. Can we use data on the biographies of hundreds of thousands of historical figures to estimate the GDP per capita of countries and regions? Here we introduce a machine learning method to estimate the GDP per capita of dozens of countries and hundreds of regions in Europe and North America for the past 700 years starting from data on the places of birth, death, and occupations of hundreds of thousands of historical figures. We build an elastic net regression model to perform feature selection and generate out-of-sample estimates that explain 85% of the variance in known historical GDPs per capita. We use this model to generate GDP per capita estimates for countries, regions, and time periods for which this data is not available and validate them by comparing them with three proxies of economic output: body height in the 18th century, wellbeing in 1850, and church building activity in the 14th and 15th century. Additionally, we show our estimates reproduce the well-known reversal of fortune between southwestern and northwestern Europe between 1300 and 1800. These findings validate the use of fine-grained biographical data as a method to produce historical GDP per capita estimates. We publish our estimates with appropriate confidence intervals together with all collected source data in a comprehensive dataset.

István Herbály, CEO, Contrall Ltd. Title: Artificial Intelligence: basics of the technology and current issues Issues: These are just some of the questions about Artificial Intelligence that many of us ask ourselves when we read or hear something about this technology almost every day. The aim of the workshop is to build a common knowledge base, followed by a joint discussion of questions like the above.
