The proliferation of digital platforms has transformed economic behaviour, reshaping traditional markets and creating new avenues for interaction.

Chapter 3 investigates user behaviour in online second-hand marketplaces, focusing on the clothing sector. The study assesses how visual elements in product listings affect sales and pricing strategies. The key factor analysed is the subject type (clothing alone, real person, catalogue image, or professional model) and its impact on listing prices, sale likelihood, and time to sale.

La diffusione delle piattaforme digitali ha trasformato l'economia, ridefinendo i mercati tradizionali e creando nuove opportunità di interazione. Accelerata dalla pandemia di COVID-19, la dipendenza dalle soluzioni digitali è aumentata in tutti i settori. Caratterizzate da mercati multilaterali, effetti di rete e scalabilità, queste piattaforme hanno influenzato industrie, consumatori e sollevato questioni normative ed etiche. Questa tesi esamina i cambiamenti economici e sociali indotti dalle piattaforme digitali, concentrandosi su tre ambiti: voto strategico, consumo politico e mercati online. Il primo studio analizza il voto strategico in elezioni su larga scala (televoto) e su piccola scala (giurie), usando dati di Eurovision e Spotify. I risultati mostrano che il voto strategico avviene con diversa intensità in entrambi i contesti, con i dati del contest più influenti di quelli di Spotify. Questo approfondimento fornisce spunti sul comportamento elettorale con implicazioni per la governance politica e aziendale. Il secondo studio esamina l'impatto della nomina del giudice Brett Kavanaugh alla Corte Suprema degli Stati Uniti sul consumo musicale. Utilizzando dati di streaming da Spotify, lo studio verifica se questo evento abbia influenzato il consumo di musica di artiste donne. Un'analisi difference-in-differences indica un aumento del 16\% nel consumo di musica femminile rispetto a quella maschile. Inoltre, le canzoni con tematiche di empowerment femminile hanno guadagnato popolarità. Il terzo studio analizza il comportamento degli utenti nei mercati online di seconda mano, con un focus sul settore dell'abbigliamento. Lo studio valuta l'impatto degli elementi visivi nelle inserzioni su prezzi e vendite. Il tipo di immagine (capo solo, persona reale, catalogo, modello) influisce su prezzo e tempi di vendita. Un'analisi di regressione mostra che immagini personali, nonostante le implicazioni sulla privacy, possono favorire prezzi più alti o vendite più rapide, variando per categoria. Questa ricerca offre spunti sulle dinamiche delle piattaforme digitali, con implicazioni per strategie aziendali, regolamentazione e comportamento dei consumatori.

Abstract
The proliferation of digital platforms has transformed economic behaviour, reshaping traditional markets and creating new avenues for interaction. Accelerated by the COVID-19 pandemic, reliance on digital solutions has intensified across sectors. Characterized by multisided markets, network effects, and scalability, these platforms have disrupted industries, altered consumer behaviour, and raised regulatory and ethical concerns. This thesis examines shifts in economic and societal behaviour induced by digital platforms, focusing on three interconnected domains: strategic voting, political consumerism, and user engagement in online marketplaces. Chapter 1 explores strategic voting in large-scale (televote) and small-scale (jury) elections within a positional voting system, using Eurovision and Spotify data. Findings reveal that strategic voting occurs to varying degrees in both televote and juries, with contest-generated data carrying more weight than Spotify data. This analysis underscores the prevalence of strategic voting and offers insights into voter behaviour, with broader implications for political and corporate governance. These findings provide important context for understanding the nuances of voting behaviour. Chapter 2 examines the impact of Justice Brett Kavanaugh’s appointment to the US Supreme Court on music consumption patterns. Using Spotify streaming data, the study tests whether this political event influenced consumer behaviour, particularly boosting consumption of music by female artists. A difference-in-differences analysis indicates a 16\% increase in consumption for female performers compared to males. Lyrical analysis further shows that songs addressing sexism and female empowerment grew in popularity during this period. The study contextualizes these shifts within broader trends. Chapter 3 investigates user behaviour in online second-hand marketplaces, focusing on the clothing sector. The study assesses how visual elements in product listings affect sales and pricing strategies. The key factor analysed is the subject type (clothing alone, real person, catalogue image, or professional model) and its impact on listing prices, sale likelihood, and time to sale. Regression analysis incorporating user experience, product reviews, and descriptions highlights the significance of visual presentation alongside reputation.
