Повний текст джерелаThis thesis analyzes banks’ choices over their leverage ratio targeting. It is commonly believed that the banks’ leverage ratio is implicitly driven by the risk-related regulation set by the Basel Committee. Many recent empirical studies on the subject challenge this presumption and suggest that factors other than regulation drive the banks’ choices on leverage. A review of the recent contributions on the subject is presented in the first chapter. In the second chapter we study how capital requirements affect banks' capital structure within a standard signaling model. We prove the existence of a separating equilibrium in which capital requirements are not binding for every type of bank, and we show that in equilibrium there exists a negative relationship between bank's leverage and its intrinsic quality: it is the low type bank that takes on more debt. This result, in contrast with the traditional theory of corporate finance, sheds some light on some of the recent financial crises episodes and hence questions the effectiveness of the current regulatory environment. Finally, in the last chapter, we conduct an empirical analysis on the cross-sectional determinants of banks' leverage. We find a negative and stable relation between banks leverage and the quality of their assets. This result is proved valid under different definition of assets' quality, based on ex-ante and ex-post expectation of the realization of asset quality. The results suggest that banks might target a certain leverage ratio to reveal their true quality to the market: the higher quality banks signal their private information to the market with a lower level of leverage, passing over some profitable opportunities to gain from a lower cost of funding.

Повний текст джерелаThe 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.

Повний текст джерелаEquity crowdfunding (hereafter ECF) is a recent phenomenon that leads entrepreneurial finance to take advantage of innovative digital facilities allowing ventures to obtain alternative financing: nascent entrepreneurs can raise capital from a crowd of investors, who generally contribute with modest individual amounts, during a web-based campaign for a certain period. ECF represents an innovative form of seed financing for new ventures. Following a pecking order approach, entrepreneurs might opt for this alternative financing scheme in the case that internal funds, external debt or external equity might not be sufficient or available. ECF belongs to the Fintech environment and thus to the digital finance theoretical framework. It exploits availability of digital platforms able to support entrepreneurs in overcoming financial constraints, particularly relevant in the initial steps of ventures. Investors in ECF must take decisions in a highly risky environment, with high levels of uncertainty. Moreover, potential profits (if any) would be appreciable only in a longer term and are subject to both liquidity and market risks. Therefore, the evaluation of the risk-return profile of an investment project is based on a multitude of determinants and encompasses a wide spectrum of disciplines. All this explains why recent crowdfunding literature has followed rapid growth, and many authors have studied ECF from various perspectives and disciplines, following complementary points of view to understand what convinces the public to invest, determining the success, or failure of a fundraising campaign. The thesis focuses on the equity crowdfunding from the perspectives of both entrepreneurs and investors. The theoretical background is built upon a multidisciplinary integrative framework. The aim of this research project is to analyse the dynamics of funding campaigns of new ventures on ECF platforms and identify the determinants of success. Assuming that investors refine their decision-making through observational learning of various signals, the empirical settings hypothesize that an information cascade from different sources impacts on the outcome of the campaign by inducing herding. The thesis is structured as a collection of papers and is articulated in three studies. The first study consists of a systematic and bibliometric review of the literature on the determinants of the success or failure of an equity crowdfunding campaign, with particular leverage on the signaling technique as a tool to alleviate information asymmetries by entrepreneurs/management and is aimed at identifying the research gaps where to position the two subsequent studies. The second study follows the perspective of investors and is part of the literature of information cascade and herding. It observes investment decisions in the context of equity crowdfunding through a choice experiment with the aim to empirically verify the hierarchy of sources that affect the willingness to invest. In fact, it is assumed that retail investors perfect their decision-making framework through the observation of information cascades deriving from more informed/experienced parties. The third study examine the perspective of entrepreneurs. The aim is to identify the signals that affect the outcome of a funding campaign, among those conveyed via information cascades. Following the Theory of Planned Behavior, in fact, the objective of this third work is to move from investment intentions (study 2; analyzed experimentally) to the concrete behavior of investors (observed in real data).

Повний текст джерелаThis thesis presents three bank-related research studies inspired by some relevant events brought about by the recent subprime banking crisis. The first part of this work links banking-sector liquidity creation to both liquidity supply from central banks worldwide and international interbank liabilities, within a global macro-econometric framework. In the second part it is carried out a micro-econometric analysis on all global US banks with the intent to explain pre- and post-crisis dynamics in Net Inter-Office Accounts (NIOA). The last part of the thesis proposes a framework capable to model, among other things, inefficient policy interventions by a central banker during a crisis when an accurate assessment of the true solvency of a bank is unattainable.

Повний текст джерелаIn this thesis we consider the application of Sequential Monte Carlo (SMC) methods to continuous-time asset pricing models. The first chapter of the thesis gives a self-contained overview on SMC methods. In particular, starting from basic Monte Carlo techniques we move to recent state of the art SMC algorithms. In the second chapter we review existing methods for the exact simulation of Hawkes processes. From our analysis we infer that the simulation scheme of Dassios and Zaho (2013) outperforms the other algorithms, including the most popular thinning method proposed by Ogata (1980). This chapter serves also as introduction to self-exciting jump processes, which are the subject of Chapter 3. Hence, in the third chapter we propose a new self-exciting jump diffusion model in order to describe oil price dynamics. We estimate the model by applying a state of the art SMC sampler on both spot and futures data. From the estimation results we find evidence of self-excitation in the oil market, which leads to an improved fit and a better out of sample futures forecasting performance with respect to jump-diffusion models with constant intensity. Furthermore, we compute and discuss two optimal hedging strategies based on futures trading. The optimality of the first hedging strategy proposed is based on the variance minimization, while the second strategy takes into account also the third-order moment contribution in considering the investors attitudes. A comparison between the two strategies in terms of hedging effectiveness is provided. Finally, in the fourth chapter we consider the estimation of continuous-time Wishart stochastic volatility models by observing portfolios of weighted options as in Orlowski (2019). In this framework we don't know the likelihood in closed-form; then we aim to estimate it using SMC techniques. To this end, we marginalize latent states and perform marginal likelihood estimation by adapting the recently proposed controlled SMC algorithm (Heng et. Al. 2019). From the numerical experiments we show that the proposed methodology gives much better results with respect to standard filtering techniques. Therefore, the great stability of our SMC method opens the door for effective joint estimation of latent states and unknown parameters in a Bayesian fashion. This last step amounts to design an SMC sampler based on a pseudo-marginal argument and is currently under preparation.

Повний текст джерелаDoes the provision of formal microcredit increase access to credit of rural clients and efficiency of credit markets? This study tackles this question through the development of a theoretical model and an empirical analysis in an Ethiopian village. In a dual (formal/informal) financial market, the theoretical model suggests that when some members of the informal arrangement get a formal loan, all members benefit from it. The agents who have a current deficit have greater financial resources whereas the agents who have an expected future deficit enjoy looser participation constraints. Furthermore, when the interest rate charged on formal loans decreases, the utility of not only borrowing members but all members in the arrangement increases. Besides, the formal market crowds out the informal market to some extent as long as the formal loan size increases or the interest rate decreases. Evidence from the rural village in southern Ethiopia only weakly confirms the theoretical results because of two reasons. First, due to different size and maturity of loans, the formal microcredit services and the informal risk sharing arrangements appear to be complements in the local market. Second, the group lending approach seems to replicate the same selection and monitoring processes of the informal arrangements and the low-income households remain constrained in their access to credit. Therefore, MFIs that want to operate successfully in rural areas should, first, make an assessment of self-selection processes in the informal arrangements and, second, provide a wider range of financial products besides credit, such as savings and insurance products.

Повний текст джерелаThe aim of this doctoral thesis is to produce an extensive analysis of medium-run macroeconomics and its main related phenomenon, the financial cycle. The revision of overall literature is proposed in the first chapter, while new empirical results are presented in chapters two and three. Modern macroeconomic research emphasised the presence of medium-term fluctuations in financial time series, which affect the business cycle. The cyclical behaviour of variables such as mortgages, private debt and house prices has a serious impact on real GDP dynamics. Then, in chapter two a new method for spectral analysis (Continuous Wavelet Transform) is introduced to inspect peaks in frequency and durations of macro cycles. Finally, chapter three proposes a structural VAR model, where real and financial shocks are identified through sign restrictions. Results from spectral analysis confirm the presence of deep interconnections between real GDP and financial variables, especially at frequencies above the usual business cycle convention (i.e, above 32 quarters). Lastly, impulse responses and variance analysis from chapter three display advances in interpreting the nature of financial shocks and their effects.

Повний текст джерелаThe financial crisis that erupted in 2008 translated into harsh recessionary effects at an international level, that were passed on to the real economy. A solid recovery is still lagging behind. The dissertation contributes to the econometric literature on the great recession by focusing attention on two debated topics: financing constraints and total factor productivity (TFP). The fragmented and strongly bank-dependent Italian production base is a preferred environment to conduct the analysis. The role played by financing constraints as amplifiers of manufacturing dynamics is firstly investigated. As a second step, financial rigidity of firms and contagion effects that occurred via trade credit interconnections are considered, and jointly modelled as core determinants of distress likelihoods by resorting to spatial econometric techniques. In the last section, geographical and sectoral clustering phenomena are spatially analyzed in order to investigate knowledge spillovers at the micro level. Results highlight the pervasive nature of the last crisis. The harshness of the recessionary effects fostered a change in manufacturing equilibria and caused the proliferation of distress episodes. Nevertheless, a clustered production base still represents a driver for the formation of positive externalities.

In Essay Two, I analyse fund of hedge funds (FOHFs). I find several interesting results. First, FOHFs and the sub-strategies earn positive excess returns and a high Fung and Hsieh 7-factor alpha. Second, FOHFs and the sub-strategies underperform the hedge fund index (HFI). Third, the correlations between FOHF indices and equity index are lower than correlations between HFI and equity indices. Finally, hedge funds and FOHFs are positively correlated with the equity index in the bear markets but uncorrelated with the equity index in the bull markets. Compared to HFI, FOHF indices have lower correlation with equity index in both bull and bear markets, indicating that FOHFs provide better diversification benefits than individual hedge funds.

Повний текст джерелаThis thesis focuses on a crucial and controversial issue - liquidity risk. After the 2007-2008 crisis it became increasingly important. The Central Banks provide required liquidity to minimise the probability of a financial system meltdown by using a wide array of instruments. This thesis proposes an analyses of the European Central Bank quantitative policy, market conditions in which these measures have been taken, and their consistency with the demand for liquidity by the banking system. The Basel III international regulatory framework introduced new liquidity regulations for managing liquidity risk. This study introduces a number of actions that can be performed to improve a bank’s liquidity risk management capabilities. By applying the simulation-based approach to decision making, a sensitivity analysis was used to determine the impact of managerial rulings on liquidity ratio. The present work highlights the importance of the liquidity risk and presents the empirical analysis that allowed the exploration of the relationship between the Basel’s new liquidity requirement (NSFR) and banking stability, macroeconomic and financial markets factors, and central bank operations.

Повний текст джерелаThe study named "European Energy Security: the Substitutability of European Crude Oil Imports from Russia" is meant to be a contribution to the current debate on the diversification possibilities in EU for reducing the dependency on Russian crude oil and ensuring the energy security of the European Union (EU). We focus on the aggregate demand for crude oil in EU with the aim of investigating the degree of substitutability of crude oil imports from the Former Soviet Union countries (FSU) and crude oil imports from four alternative regions (America, Middle East, Europe, Africa). Following Fuss (1977) and Serletis (2010) we employ an econometric model of intra-fuel substitution, using a nonlinear seemingly unrelated regression (SUR) estimator, to assess the aforementioned degree of substitutability in terms of Morishima elasticities of substitution. We use the most recent dataset, published by the European Commission, consisting of a collection of imported volumes and CIF prices of crude oil by country of origin. The results indicate that the crude oil provided by former Soviet Union (FSU) countries is strongly substitutable with those imported from African and Middle Eastern countries whilst it is not substitutable with those imported from European and American countries.
Predictability Information Criterion for Selecting Stochastic Pricing Models: pricing models of derivative instruments usually fail to provide reliable results when risks rise and financial crises occur. More advanced stochastic pricing models try to improve the fitting results adding risk factors and/or parameters to the models, incurring the risk of overfitted results. Drawing on these observations, it is proposed a generalization of the Akaike Information Criterion (AIC) suitable to evaluate forecasting power of alternative stochastic pricing models for any fixed arbitrary forecasting time-horizon. The Predictability Information Criterion (PIC) differs from the classical criteria for evaluating statistical models as it assumes that the random variable to study can (or cannot) be partially predictable, which makes it particularly suitable for studying stochastic pricing models coherently with the semimartingale definition of the price process. On the basis of this assumption the criterion measures and compares the uncertainty of the predictions of two different alternative models when prices are (or are not) predictable. We conclude with a focus on the crude oil market by comparing GBM and OU stochastic processes that are commonly used for modeling West Texas Intermediate (WTI) oil spot price returns in derivative pricing models.

Повний текст джерелаUsing the fixed effect estimator, this paper analyzes the profitability of 11 private banks in Syria over the period from 2007:Q1 to 2018:Q4. To evaluate the impact of the Syrian crisis (civil war), we separately consider the pre-crisis period, 2007:Q1-2012:Q4, and the crisis period of 2013:Q1-2018:Q4. Our profitability determinants include bank-specific characteristics as well as industry-specific and macroeconomic factors, some of which have not been considered in previous studies. The inclusion of these additional factors as well as the separate consideration of the crisis years allow us to gain new insights into what determines the profitability of private banks in Syria. Our results clearly show that there exist large differences in profitability among our sample banks and that a significant amount of this variation can be explained by the factors included in our analyses.
Unlike the past literature which focuses on studying the effects of bank efficiency on the bank performance (in the same period) using different methodologies to assess how differences in the efficiencies obtained across the different methods lead to different impacts, we test the impacts of bank efficiency of the Syrian banking sector in normal times on bank performance (risk & profitability) during the subsequent crisis. We extend the work of Assaf et al. (2019) by opting to use two different methodologies; Stochastic Frontier Analysis (SFA) and Free Distribution Approach (FDA) to estimate cost and profit efficiencies during normal times and assess how the different methodologies lead to different impacts of the estimated efficiencies on bank performance during crisis times assuming two scenarios for the estimation of inefficiencies; the first is a time-invariant inefficiency while the second is a time-varying inefficiency. With respect to bank risk, we find that cost efficiency during normal times was translated into increasing banks risk, under time-invariant and time-varying inefficiency. However, we find that profit efficiency has a negative impact on bank risk during the subsequent crisis under timeinvariant and time-varying inefficiency. This suggests that cost efficiency may better proxy management quality, while profit efficiency may partially reflect temporary high returns during normal times from low-risk investments that are reversed during the subsequent crisis. With respect to bank profitability, we find that cost efficiency, during normal times, was translated into helping banks to increase their profitability under the time-invariant inefficiency. However, the results were contradictory under the time-varying inefficiency. On the other hand, profit efficiency in the pre-crisis period seems to be conclusive with respect to its negative impact on profitability during the subsequent crisis. This was proven based on the results of two models under time-invariant inefficiency and one model under timevarying inefficiency suggesting that bank managers were tending to engage in high revenues-low risk activities in the period prior to the outbreak of the Syrian crisis. Findings have policy implications and imply policymakers, regulators and supervisors should consider more sophisticated means of monitoring and surveillance of banks characterized with high-cost efficiency as early as possible in order to decrease and minimize the occurrence of potential problems that might surface during future financial crises. In addition, bank managers should focus on utilizing policies and procedures that promote and foster cost efficiency, which may drive better bank performance and enhance the response of banks to possible negative shocks during any subsequent crises.
