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.

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 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.

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 dissertation aims to contribute to the ongoing discourse on the effect an enhanced financial literacy, through financial education, has on financial behaviour. We posit that financial literacy is enhanced through financial education courses, but it also significantly impacts the financial behaviour of individuals. Moreover, we argue that improved financial literacy plays a significant role in mitigating behavioural biases and an asset price bubble. Chapter 1 analyzes the impact of a financial education course in enhancing financial literacy in a high- school context. Students at specific schools in Tirana, Albania, are delivered a financial education course, which lasts one academic year. To understand the impact of this financial education course in enhancing financial literacy, PISA (2012) questionnaire on financial literacy is delivered to the students before and after the course is delivered. Chapter 2 analysis the impact of financial literacy in mitigating behavioural biases. We focus on the impact that enhanced financial literacy through the financial education course and financial education plays in reducing the propensity to mental accounting bias. Chapter 3 investigates how financial literacy affects the propensity to an asset price bubble occurrence. We posit that enhanced financial literacy through financial education reduces the probability of an asset price bubble occurrence. We find that financial literacy enhanced through financial education has a significant impact in the financial behaviour of the individuals.

Nell’attuale situazione di crisi diviene sempre più importante per le aziende il ruolo della comunicazione economico-finanziaria. Quest’ultima dovrebbe essere utilizzata come elemento determinante per chiarire il cambiamento in atto e far riacquisire la credibilità delle imprese stesse. La tesi è suddivisa in una prima parte teorica e in una seconda parte di analisi empirica. Nella prima parte viene analizzato il ruolo e le caratteristiche dell’informativa economico-finanziaria, le maggiori teorie riguardanti la comunicazione e il legame di quest’ultime con l’attuale crisi economica. La seconda parte concerne invece l’analisi empirica del settore bancario e in particolare modo la comunicazione di quest’ultimo con il mercato dei capitali.
