Solving Four Open Problems about Core Stability in Altruistic Hedonic Games
Jörg Rothe, Ildikó Schlotter
Hedonic games -- at the interface of cooperative game theory and computational social choice -- are coalition formation games in which the players have preferences over the coaliti…
An experimental approach: Converting verbal expressions to numerical scales
Zsombor Szádoczki, Sándor Bozóki, László Sipos +1
One of the key issues in decision problems is the selection and use of the appropriate response scale. In this paper verbal expressions are converted into numerical scales for a su…
Evolution and determinants of firm-level systemic risk in local production networks
Anna Mancini, Balázs Lengyel, Riccardo Di Clemente +1
Recent crises like the Covid-19 pandemic and geopolitical tensions have exposed vulnerabilities and caused disruptions of supply chains, leading to product shortages, increased cos…
The Software Complexity of Nations
Sándor Juhász, Johannes Wachs, Jermain Kaminski +1
Despite the growing importance of the digital sector, research on economic complexity and its implications continues to rely mostly on administrative records, e.g. data on exports,…
The dynamics of leadership and success in software development teams
Lorenzo Betti, Luca Gallo, Johannes Wachs +1
From science to industry, teamwork plays a crucial role in knowledge production and innovation. Most studies consider teams as static groups of individuals, thereby failing to capt…
Urban highways are barriers to social ties
Luca Maria Aiello, Anastassia Vybornova, Sándor Juhász +2
Urban highways are common, especially in the US, making cities more car-centric. They promise the annihilation of distance but obstruct pedestrian mobility, thus playing a key role…
How to measure consumer's inconsistency in sensory testing?
László Sipos, Kolos Csaba Ágoston, Péter Biró +2
Standard methods, standard test conditions and the use of good sensory practices are key elements of sensory testing. However, while compliance assessment by trained and expert ass…
Quantifying Barriers of Urban Mobility
Gergő Pintér, Balázs Lengyel
Barriers in cities, such as administrative boundaries, natural obstacles, railways or major roads are thought to induce segregation. However, the empirical knowledge about this phe…
Couples can be tractable: New algorithms and hardness results for the Hospitals / Residents problem with Couples
Gergely Csáji, David Manlove, Iain McBride +1
In this paper, we study the Hospitals / Residents problem with Couples (HRC), where a solution is a stable matching or a report that none exists. We present a novel polynomial-time…
Are Large Language Models a Threat to Digital Public Goods? Evidence from Activity on Stack Overflow
Maria del Rio-Chanona, Nadzeya Laurentsyeva, Johannes Wachs
Large language models like ChatGPT efficiently provide users with information about various topics, presenting a potential substitute for searching the web and asking people for he…
Odd Paths, Cycles and -joins: Connections and Algorithms
Ildikó Schlotter, András Sebő
Minimizing the weight of an edge set satisfying parity constraints is a challenging branch of combinatorial optimization as witnessed by the binary hypergraph chapter of Alexander…
Understanding European Integration with Bipartite Networks of Comparative Advantage
Riccardo Di Clemente, Balázs Lengyel, Lars F. Andersson +1
Core objectives of European common market integration are convergence and economic growth, but these are hampered by redundancy, and value chain asymmetries. The challenge is how t…
Preallocation-based Combinatorial Auction for Efficient Fair Channel Assignments in Multi-Connectivity Networks
Dávid Csercsik, Eduard Jorswieck
We consider a general multi-connectivity framework, intended for ultra-reliable low-latency communications (URLLC) services, and propose a novel, preallocation-based combinatorial…
The efficacy of tournament designs
Balázs R. Sziklai, Péter Biró, László Csató
Tournaments are a widely used mechanism to rank alternatives in a noisy environment. This paper investigates a fundamental issue of economics in tournament design: what is the best…
Bibliometric indices as a measure of performance and competitive balance in the knockout stage of the UEFA Champions League
László Csató, Dóra Gréta Petróczy
We argue for the application of bibliometric indices to quantify the long-term uncertainty of outcome in sports. The Euclidean index is proposed to reward quality over quantity, wh…
Business disruptions from social distancing
Miklós Koren, Rita Pető
Social distancing interventions can be effective against epidemics but are potentially detrimental for the economy. Businesses that rely heavily on face-to-face communication or cl…
Convex Combinatorial Auction of Pipeline Network Capacities
Dávid Csercsik
In this paper we propose a mechanism for the allocation of pipeline capacities, assuming that the participants bidding for capacities do have subjective evaluation of various netwo…
Inequality is rising where social network segregation interacts with urban topology
Gergő Tóth, Johannes Wachs, Riccardo Di Clemente +4
Social networks amplify inequalities due to fundamental mechanisms of social tie formation such as homophily and triadic closure. These forces sharpen social segregation reflected…
Ride-share matching algorithms generate income inequality
Eszter Bokányi, Anikó Hannák
Despite the potential of online sharing economy platforms such as Uber, Lyft, or Foodora to democratize the labor market, these services are often accused of fostering unfair worki…
Self-respecting worker in the precarious gig economy: A dynamic principal-agent model
Zsolt Bihary, Péter Csóka, Péter Kerényi +1
We develop a continuous-time principal-agent model of gig work, where contractual flexibility allows the employer to adjust fixed pay and output-based incentives dynamically. The w…
Modelling transfer profits as externalities in a cooperative game-theoretic model of natural gas networks
Dávid Csercsik, Franz Hubert, Balázs R. Sziklai +1
Existing cooperative game theoretic studies of bargaining power in gas pipeline systems are based on the so called characteristic function form (CFF). This approach is potentially…
Taking census of physics
Federico Battiston, Federico Musciotto, Dashun Wang +3
Over the past decades, the diversity of areas explored by physicists has exploded, encompassing new topics from biophysics and chemical physics to network science. However, it is u…
Interdisciplinarity: A Nobel Opportunity
Michael Szell, Yifang Ma, Roberta Sinatra
Interdisciplinary collaborations now sweep most fields of the natural and life sciences, necessary to tackle the world's most challenging problems. Yet, the scientific enterprise c…
University rankings from the revealed preferences of the applicants
László Csató, Csaba Tóth
A methodology is presented to rank universities on the basis of the lists of programmes the students applied for. We exploit a crucial feature of the centralised assignment system…
