We investigate how the spectral risk measure associated with holding stocks rather than a riskfree deposit, depends on the holding period. Previous papers have shown that within a limited class of spectral risk measures, and when the stock price follows specific processes, spectral risk becomes...

To efficiently assess the performance of investing in stocks rather than in a bank account for the long run, stochastic interest rate modelling is advocated. We introduce a correlated stochastic interest rate model that addresses this problem. We derive analytic formulas for general spectral...

A hosszú távon befektetők (például nyugdíjalapok, céldátum-eszközalapok és fiatal befektetők) számára fontos kérdés, hogy mennyire kockázatos hosszú távon részvényt tartani. Tanulmányunk a spektrális kockázati mértékeket helyezi középpontba, amelyek a vizsgált...

The COVID-19 pandemic provides a natural experiment to comprehensively test the effect of crowds on both referees and players. Our aim is to examine this from a North-American perspective using data from three major leagues: National Basketball Association (NBA), National Football League (NFL)...

The COVID-19 pandemic provides a natural experimental framework to comprehensively test the effect of crowds on both referees and players. We examine this from a North American perspective, using data from three major leagues: the National Basketball Association (NBA), National Football League...

We demonstrate that margin requirements of central counterparties show a significantly different behavior when calculated with a portfoliowise treatment instead of taking the weighted sum of the margin requirements of the components without accounting for their correlation structures. This is...

This paper examines the effect of spectators on women’s football games. COVID-19 and related restrictions provide a unique opportunity with an adequate sample size to test the effect of lockdown on sports activities. Studies have recently exploited this opportunity for men’s football to...

Accurately valuing storage in the electricity market recognizes its role in enhancing grid flexibility, integrating renewable energy, managing peak loads, providing ancillary services and improving market efficiency. In this paper we outline an optimal trading problem for an Energy Storage...

A viselkedési pénzügyek szerint a befektetőket az érzelmeik is befolyásolják, nem racionálisan döntenek, ezzel magyarázatot szolgáltatva a tőzsdei anomália jelenségére. A tanulmányban a naptárhatás és az időjárás hatásának a meglétét vizsgáltuk 1991 és 2022 között a...

We model the consequences of the soft budget constraint in the context of retail borrowers. While János Kornai formulated the term of “soft budget constraint” mainly for organizations (firms, banks, municipalities, NGOs, etc.), we show that it can be applied to individual borrowers as well....
