In the present thesis I study the contribution to firm value of inventories management from a risk management perspective. I find a significant contribution of inventories to the value of risk management especially through the operating flexibility channel. In contrast, I do not find evidence supporting the view of inventories a reserve of liquidity. Inventories substitute, albeit not perfectly, derivatives or cash holdings. The substitution between hedging with derivatives and inventory is moderated by the correlation between cash flow and the underlying asset in the derivative contract. Hedge ratios increase with the effectiveness of derivatives. The decision to hedge with cash holdings or inventories is strongly influenced by the degree of complementarity between production factors and by cash flow volatility. In addition, I provide a risk management based explanation of the secular substitution between inventories and cash holdings documented, among others, in Bates et al. (2009), Journal of Finance. In a sample of U.S. firms between 1980 and 2006, I empirically confirm the negative relation between inventories and cash and provide evidence on the poor performance of investment cash flow sensitivities as a measure of financial constraints also in the case of inventories investment. This result can be explained by firms' scarce reliance on inventories as a reserve of liquidity. Finally, as an extension of my study, I contrast with empirical data the theoretical predictions of a model on the integrated management of inventories, trade credit and cash holdings.

This Ph.D. thesis consists in three research papers focused on the relationship between media industry and the financial sector. The importance of a correct understanding what is the effect of media on financial markets is becoming increasingly important as long as fully informed markets hypothesis has been challenged. Therefore, if financial markets do not have access to complete information, the importance of information professionals, the media, follows. On the other side, another challenge for economic and finance scholar is to understand how financial features are able to influence media and to condition information disclosure. The main aim of this Ph.D. dissertation is to contribute to a better comprehension for both the phenomena. The first paper analyzes the effects of owning equity shares in a newspaper- publishing firm. The main findings show how for a firm being part of the ownership structure of a media firm ends to receive more and better coverage. This confirms the view in which owning a media outlet is a source of conflicts of interest. The second paper focuses on the effect of media-delivered information on financial markets. In the framework of IPO in the U.S. market, we found empirical evidence of a significant effect of the media role in the IPO pricing. Specifically, increasing the quantity and the quality of the coverage increases the first-day returns (i.e. the underpricing). Finally the third paper tries to summarize what has been done in studying the relationship between media and financial industries, putting together contributes from economic, business, and financial scholars. The main finding of this dissertation is therefore to have underlined the importance and the effectiveness of the relationship between media industry and the financial sector, contributing to the stream of research that investigates about the media role and media effectiveness in the financial and business sectors.

In this thesis I construct a unique dataset to test the role of individual characteristics in affecting the investor behaviour. In particular, I present two empirical research papers that investigate trading patterns unlikely to be driven by rational models, and a literature review in which are summarized the main findings within the new field of “personality finance”. Using an experimental analysis that combine a trading simulation with a Big-Five personality questionnaire, Paper 1 and Paper 2 illustrate how personality affects the individual level of disposition effect and trading volume respectively. In detail, among a sample of 230 students, in the first paper I find strong heterogeneity in the level of disposition effect recorded. In explaining these differences and controlling for demographic variables, I show that the trait of extroversion is positively related with tendency to sell stocks at gain rather than at loss, while subjects with high conscientiousness and openness to experience are less biased. In a different sample of 176 students, from Paper 2, I demonstrate that emotionally stable investors are more likely to exhibit higher trading volume, while high-conscientiousness seems to weaker it. Demographics and risk-attitude measures moderate the individual in- vestment choices. Finally, in the third paper I introduce a literature review on those works in which the personality of the investors is used to explain subjects trading performance and specific financial phenomena. I try to organize the main findings from this new field, named “personality finance”, identifying the psychological sources that can predict the heterogeneity in the individual investment behaviour.

This thesis examines the literature on local home bias, i.e. investor preference towards geographically nearby stocks, and investigates the role of firm’s visibility, profitability, and opacity in explaining such behavior. While firm’s visibility is expected to proxy for the behavioral root originating such a preference, firm’s profitability and opacity are expected to capture the informational one. I find that less visible, and more profitable and opaque firms, conditionally to the demand, benefit from being headquartered in regions characterized by a scarcity of listed firms (local supply of stocks). Specifically, research estimates suggest that firms headquartered in regions with a poor supply of stocks would be worth i) 11 percent more if non-visible, non-profitable and non-opaque; ii) 16 percent more if profitable; and iii) 28 percent more if both profitable and opaque. Overall, as these features are able to explain most, albeit not all, of the local home bias effect, I reasonably argue and then assess that most of the preference for local is determined by a successful attempt to exploit local information advantage (60 percent), while the rest is determined by a mere (irrational) feeling of familiarity with the local firm (40 percent). Several and significant methodological, theoretical, and practical implications come out.

Utilizzando un campione di imprese non finanziarie quotate appartenenti all'area euro, analizzo le determinanti della struttura finanziaria aziendale. Coerentemente con il tradizionale approccio teorico, utilizzo una misura dell'indebitamento a valori di mercato, stimato col modello di Black-scholes-merton. alcune variabili analizzate hanno effetti simili nei vari paesi, mentre altre cambiano: il rischio, misurato con la volatilità del valore di mercato dell'attivo, è la variabile più rilevante. Il rischio e l'asimmetria informativa su di esso rendono il debito meno attraente, a causa di maggior costi attesi di fallimento, minore vantaggio fiscale e maggiori costi di agenzia. La nazionalità influenza le scelte finanziarie. l'integrazione dei mercati finanziari nell'area euro cambia significativamente a seconda dei segmenti di mercato considerati: il mercato monetario ed interbancario sono fortemente integrati, il mercato obbligazionario ed azionario mostrano di essere su un percorso di integrazione, il mercato del credito bancario è ancora molto frammentato. le normative fiscali e fallimentari differiscono nei dodici paesi, come anche il contesto economico. / Using a sample of non-financial listed firms located in the Euro area, I investigate the determinants of capital structure choices. In line with the traditional theoretical approach, I use a market-value measure of leverage, estimated with the Black-Scholes-Merton model. I find that some variables have similar effects across countries, while others may play a different role; risk, measured as the volatility of the market enterprise value, is the best predictor of observed leverage ratios. Risk, and asymmetric information about risk, make debt less attractive, because of higher expected bankruptcy costs, lower expected debt tax shield and higher agency costs. National environments are an important determinant of observed ratios. The integration of Euro-area financial markets varies significantly depending on the market segment considered: money and inter-bank markets are highly integrated, corporate bond and equity markets show a clear path of increasing integration, retail banking markets are much less integrated. Fiscal and bankruptcy rules differ across the twelve countries; the economic background varies as well.

Il presente lavoro di tesi analizza da un punto di vista teorico i contratti di debito con collaterale e la scelta di specializzazione degli asset produttivi. Le imprese soggette a vincoli finanziari danno in pegno i loro asset come collaterale per migliorare l’accesso al credito. Tuttavia, i prenditori di fondi trovano spesso difficoltà nel finanziare progetti con asset eccessivamente specializzati perché il loro valore di liquidazione è basso (asset troppo specializzati hanno un valore di riutilizzo limitato) anche quando i progetti hanno un rendimento atteso elevato. In questo contesto, questa tesi vuole rispondere alle seguenti domande di ricerca: in quale modo la scelta di specializzare un asset produttivo influisce sui contratti finanziari? Quali sono gli effetti delle diverse scelte di specificità su quantità e condizioni del credito? E sulla competizione nel mercato del prodotto? La tesi tratta sia temi di finanza aziendale che temi di organizzazione industriale, e, utilizzando un nuovo approccio teorico, analizza congiuntamente il grado di specificità degli asset e il loro valore di liquidazione. La specializzazione degli asset aumenta il ritorno dei progetti ma diminuisce il valore di liquidazione degli asset stessi. Quando le imprese devono impegnare gli asset come collaterale, questo implica un aumento del costo del debito. Analizzando questo “specificity trade-off”, la tesi dimostra che: nel mercato secondario il valore di liquidazione di un asset dipende dal grado di specificità, dai costi di riutilizzo e dalla presenza di potenziali acquirenti; imprese che devono ricorrere a finanziamenti investono meno in specializzazione degli asset rispetto a imprese che riescono ad auto-finanziarsi; la struttura del mercato e il grado di specializzazione scelto sono influenzati dalle condizioni finanziarie; quando il grado di specificità degli asset produttivi influisce sul grado di differenziazione dei prodotti, il trade-off implica che le imprese che devono finanziarsi attraverso il mercato dei capitali investono meno in specializzazione e, di conseguenza, sono esposte ad un grado di concorrenza maggiore nel mercato del prodotto. / My dissertation is about collateral debt contracts and the choice of specializing productive assets, from a theoretical perspective. Financially constrained firms pledge their productive assets as collateral in order to enhance their access to credit. However, firms may find it difficult to finance projects when their collateralized productive assets are too specialized since their liquidation value is low (as a matter of fact redeployability of those assets to alternative uses is scarce) even when their projects have large expected returns. In this context, my dissertation aims to answer the following research questions: how does the choice of asset specialization affect financial contracts? Which are the implications of different degree of asset specificity for the amount of credit and product market competition? This dissertation is at a cross road between industrial organization and corporate finance and uses a novel approach where the choice of asset specialization and the liquidation value of a productive asset are analyzed together. Asset specialization increases firms' project returns, but decreases the liquidation value of productive assets. When firms are credit constrained this implies a higher cost of debt. By examining this specialization trade-off, I am able to prove the following results: in the secondary market the resale value of a productive asset is determined by its degree of asset specificity, redeployability costs and the presence of firms willing to acquire the it; financially constrained firms invest less in asset specialization compared to self-financing firms; market structure and the degree of asset specialization may be influenced by financial choices; when asset specificity affects product market differentiation, the specialization trade-off implies that financially constrained firms invest less in product differentiation, and, as a consequence, face tougher competition compared to non-financially constrained firms.

La tesi si occupa di analizzare l'impianto teorico della finanza comportamentale per comprendere il processo decisionale degli investitori al fine di applicare tali principi alla consulenza finanziaria. / The thesis is concerned with studying the theoretical structure of behavioural finance for understanding investors' decisions and then applying the results to financial advisory.

I corporate equity warrant rappresentano un affascinante metodo di finanziamento “ibrido” disponibile per le imprese. In prima approssimazione, un warrant è assimilabile ad una opzione call e, pertanto, il pricing è spesso effettuato applicando le formule di valutazione sviluppate per tali strumenti dalla teoria finanziaria. Tuttavia, la valutazione dei warrant presenta complicazioni ulteriori rispetto alla determinazione del prezzo di opzioni call, e la ragione risiede principalmente in alcuni elementi distintivi di maggiore complessità, tra cui l’effetto diluitivo del capitale esistente derivante dall’esercizio, ed il c.d. effetto “risk-shifting”, in base al quale si verifica un trasferimento di rischio sistematico dagli azionisti ai possessori di warrant, non appena questi strumenti vengono emessi. L’obiettivo di questa tesi è di analizzare il tema dell’emissione dei corporate warrant dal punto di vista della finanza d’impresa e derivare un metodo di pricing innovativo per tener conto di un fenomeno (risk-shifting effect) tuttora non considerato dalla letteratura finanziaria. Dopo aver derivato formalmente tale approccio e le formule ad esso conseguenti, il lavoro propone una simulazione teorica ed un test empirico condotto su un campione di warrant quotati sul mercato italiano. Entrambi tali verifiche dimostrano come il modello presentato incorpori una maggiore bontà previsiva del prezzo di mercato rispetto agli approcci esistenti. / Corporate equity warrants are one of the more fascinating capital-raising tools available to corporate finance officers. At a first approximation, they are option-like securities and according to this similarity, the pricing is usually performed by application of the standard option pricing theory. However, the theoretical and empirical analysis of warrants still remains an interesting research field within the finance literature. The reason is that warrants are more complex than call options. From an asset pricing point of view, the presence of some specific features (e.g., the equity dilution) prevents from using simple plain-vanilla formulas, while from a corporate finance standpoint, warrants offer several implications, principally because they affect the systematic risk of common stocks and are related to the choice of the firm’s capital structure. The purpose of this thesis is to analyse corporate warrants and address some of the main open questions about their value. In particular, after reviewing the financial literature about warrant pricing and presenting some commonly accepted formulas, the relationship between warrants and the volatility of the underlying stock return is examined. Contrarily to the classical call options, in fact, warrants affect the capital structure of the issuing firm and produce a risk-shifting effect among equity claimants. We derive an alternative approach to pricing equity warrant, embedding this risk-shifting feature, and we propose both a theoretical simulation and an empirical test based on a sample of Italian warrants proving its accuracy.
