The present thesis deals with two main phenomena: financialization and digitalization. The first chapter aims at empirically investigating the determinants of corporations' Surplus Wealth (a measure of market power) and the impact of financial investments on capital investment decisions. Overall, additional evidence on shareholders' value orientation is provided; on average, realized financial profits seem to be beneficial to both physical and intangible capital investment, whilst current financial investments appear to generate a trade-off effect (not for monopolists operating in the IT sector). The second chapter develops a theoretical agent-based model combining endogenous growth (K+S model) and financial frictions (CATS model) together with a market for corporate bonds where firms can both issue and purchase bonds. IT intangible capital is assumed to be the channel through which innovation propagates and its specific advertising properties stemming from artificial intelligence are able to foster liquidity accumulation, which is boosted when financial investments begin to play a role. Simulations suggest that, from a macroeconomic perspective, companies' purchase of corporate bonds is not beneficial to employment, technological progress and growth, except for the case where liquidity invested in bonds is beyond a common threshold across firms but at the cost of higher bankruptcy risk and Ponzi positions.
Questa tesi studia le cause e le implicazioni di due fenomeni in particolare: la finanziarizzazione e la digitalizzazione. Nello specifico, il primo capitolo contiene un'analisi empirica sulle determinanti del Surplus Wealth delle società (una misura del potere di mercato) e dell’impatto degli investimenti finanziari sugli investimenti in capitale. Complessivamente, i risultati supportano l'evidenza sulla shareholders' value orientation; in media, i profitti finanziari sembrano favorire sia gli investimenti in capitale fisico che intangibile, mentre emerge un effetto trade-off tra questi ultimi e gli investimenti finanziari (non per i monopolisti operanti nel settore IT). Nel secondo capitolo viene sviluppato un modello teorico ad agenti eterogenei che combina la crescita endogena (modello K+S) alle frizioni finanziarie (modello CATS) ed introduce un mercato obbligazionario dove le imprese possono emettere/acquistare obbligazioni societarie. L'innovazione avviene per mezzo del capitale intangibile IT, le cui proprietà intrinseche legate all’intelligenza artificiale favoriscono l'accumulazione di liquidità, accentuata poi dai profitti finanziari. Da una prospettiva macroeconomica, le simulazioni suggeriscono che gli investimenti in obbligazioni da parte delle imprese impattano negativamente sull'occupazione, frenando il progresso tecnologico e la crescita economica, salvo che la liquidità investita in bonds superi un certo valore-soglia (omogeneo tra le imprese), ma al costo di un maggior rischio di fallimento e di un incremento delle posizioni Ponzi.

Abstract
The present thesis deals with two main phenomena: financialization and digitalization. The first chapter aims at empirically investigating the determinants of corporations' Surplus Wealth (a measure of market power) and the impact of financial investments on capital investment decisions. Overall, additional evidence on shareholders' value orientation is provided; on average, realized financial profits seem to be beneficial to both physical and intangible capital investment, whilst current financial investments appear to generate a trade-off effect (not for monopolists operating in the IT sector). The second chapter develops a theoretical agent-based model combining endogenous growth (K+S model) and financial frictions (CATS model) together with a market for corporate bonds where firms can both issue and purchase bonds. IT intangible capital is assumed to be the channel through which innovation propagates and its specific advertising properties stemming from artificial intelligence are able to foster liquidity accumulation, which is boosted when financial investments begin to play a role. Simulations suggest that, from a macroeconomic perspective, companies' purchase of corporate bonds is not beneficial to employment, technological progress and growth, except for the case where liquidity invested in bonds is beyond a common threshold across firms but at the cost of higher bankruptcy risk and Ponzi positions.File | Dimensione | Formato | |
