1	Uma nova forma de medir liquidez: construção e aplicação no mercado brasileiro / A new approach to measure liquidity: construction and application in the brazilian market Silveira, Vinicius Girardi da 17 February 2017 (has links) This study aimed to construct a liquidity measure using their proxies and assess their applicability in the financial context. To that, this study proposes the creation of a negotiability measure, which is a compendium of negotiability proxies used by the literature. The statistical procedure used to obtain this measure was the time series factor analysis (TSFA), which it is an extension of traditional factor analysis, working with time series instead of cross-section data. The data used for the illustration presented came from the trading of 858 stocks on BM&FBOVESPA from January 2000 to February 2016. As a result, the measure constructed for the market was demonstrated to be consistent with the others and capable, in terms of correlation, of replacing the proxies used in its construction. In addition, it presented intermediate statistics in relation to their peers, which suggests that the measure can show more balanced results. When analyzed the applicability of the measure in liquidity pricing models, was observed that it has an explanatory power similar to the other proxies used. Having as main differential the advantage of reducing the dimensions of liquidity, considering the information contained in all proxies in only one measure. Moreover, the findings suggest no differences between the means of the measures. However, when observed the variance, the negotiability measure showed distinct from the others, presenting intermediate statistics. In this sense, it is possible to conjecture that the negotiability measure tends to present similar results when used in models based on average, as is the case of regressions. On the other hand, it may be more advantageous and accurate in models that consider variance. / O presente estudo teve o objetivo de construir uma medida de liquidez utilizando suas proxies e avaliar a sua aplicabilidade no contexto financeiro. Para tanto, este trabalho propôs a criação de uma medida de negociabilidade, a qual é um compendio de proxies de negociabilidade empregadas pela literatura. O procedimento estatístico utilizado para a obtenção desta medida foi a Análise Fatorial de Séries Temporais (TSFA), a qual é uma extensão da análise fatorial tradicional, trabalhando com séries de tempo ao invés de dados de corte. Os dados utilizados para a ilustração apresentada foram provenientes da negociação de 858 ações na BM&FBOVESPA no período de janeiro de 2000 até fevereiro de 2016. Como resultados, a medida construída para o mercado demonstrou-se consistente em relação às demais e capaz, em termos de correlação, de substituir as proxies utilizadas na sua construção. Além disso, apresentou estatísticas intermediárias em relação aos seus pares, o que sugere que a medida pode exibir resultados mais equilibrados. Quando analisada a aplicabilidade da medida em modelos de precificação com liquidez, observou-se que ela possui um poder explicativo similar as outras proxies utilizadas. Tem como principal diferencial a vantagem de reduzir as dimensões da liquidez, pois considera a informação contida em todas as proxies em apenas uma medida. Além disso, as descobertas sugeriram não haver diferenças de médias entre as medidas. Porém, quando observada a variância, a medida de negociabilidade se mostrou distinta das demais, apresentando estatísticas intermediárias. Neste sentido, é possível conjecturar que a medida de negociabilidade tende a apresentar resultados similares quando utilizada em modelos baseados em média, como é o caso das regressões. Por outro lado, pode ser mais vantajosa e precisa em modelos que considerem a variância. Liquidez Medida de negociabilidade.

2	FINANZIAMENTO DELL'IMPRESA E COAZIONE A SOTTOSCRIVERE. GLI AUMENTI DI CAPITALE IPERDILUITIVI / Highly dilutive rights issues RESTELLI, ENRICO RINO 13 April 2018 (has links) Gli aumenti di capitale iperdiluitivi causano rilevanti anomalie di mercato, soprattutto con riferimento ai diritti d’opzione, che sono spesso scambiati a un prezzo notevolmente inferiore rispetto al loro valore teorico. Come evidenziato nel Capitolo I, tali anomalie possono comportare un significativo annacquamento del valore dell’investimento, inducendo così gli azionisti a sottoscrivere le azioni offerte loro nonostante le prospettive reddituali dell’impresa avrebbero consigliato altrimenti (c.d. coazione a sottoscrivere). Al fine di trovare un adeguato equilibrio tra le esigenze di finanziamento dell’impresa e la necessità di tutelare adeguatamente gli investitori, l’ordinamento giuridico offre una pluralità di soluzioni. In quest’angolo visuale, il Capitolo II esamina il divieto di emettere nuove azioni al di sotto della parità contabile (art. 47, Direttiva (EU) 2017/1132) quale limite ex ante alla diluizione massima del valore della partecipazione azionaria, così di ridurre il rischio di comportamenti opportunistici. Similmente, nel Capitolo III si discute della funzione assolta in tali operazioni dalla responsabilità degli amministratori ex art. 2395 c.c. e ci si interroga se - nelle società quotate - l’illiquidità del mercato dei diritti di opzione costituisca un’ipotesi rilevante ai sensi dell'art. 2441, comma 5, c.c., così che tutte le nuove azioni debbano essere emesse al loro valore “reale” (co. 6). / In publicly traded companies, highly dilutive rights issues create market anomalies throughout the whole offer period, especially with respect to rights prices, which quote considerably below their fair value. As pointed out in Chapter I, these anomalies could cause severe losses to non-subscribing shareholders, inducing them to take part in the operation even if financial perspectives of the company would have suggested otherwise (= enforced subscription mechanism). In order to strike a proper balance of enabling companies to raise new capital while simultaneously protecting investors, company law provides an array of regulatory strategies. In this respect, Chapter II analyzes the prohibition on issuing new shares below par value (art. 47, Directive (EU) 2017/1132) as a means to limit the dilution that can be imposed on non-subscribing shareholders, thus hindering opportunistic behaviors. Similarly, Chapter III examines the function and the contents of managers’ liability to investors (art. 2395 Italian c.c.) and discusses whether, in these operations, the illiquidity of rights’ market can be regarded as a restriction of their pre-emption right, imposing that new shares are always issued at their “real” value (art. 2441, par. 5 - 6, Italian c.c.).

3	Finansiella instrument : En rättsekonomisk analys av värdepappersmarknadens grundläggande rättshandlingar / Financial instruments : A law and economics analysis of the fundamental contracts of the capital markets Lindblad, Anton January 2022 (has links) This thesis evaluates and constructs a general, product-neutral legal concept and model of financial instruments, as opposed to the product-dependent definitions currently employed in contemporary capital markets law. Through a combination of law and economics perspectives, legal history, and comparative analysis, the study examines the various types of financial instruments currently and previously in use. The legal characteristics and features of these instruments are evaluated and compared, leading to the identification of commonalities that can be used to define a product-neutral concept. The thesis argues that such a concept is more beneficial to the function of the capital markets by removing obstacles for financial innovation while also providing a consistent way to ensure that new financial products are governed by the same regulatory framework as comparable instruments.The thesis also examines the historical evolution of financial instruments and how it has been driven by the evolution of international trade and the demand and surplus of available capital. The proposed concept is applied to current financial instruments, including equity and debt, as well as pre-modern markets, and evaluated in terms of regulation, practical use, and legal characteristics such as transferability and negotiability.The research of this thesis encountered several challenges and limitations. Firstly, the historical and comparative analysis proved difficult to carry out, due to limitation in available source material and language related restrictions, respectively. These limitations were overcome by limiting the scope and by employing contacts with law firms in the respective jurisdictions. Secondly, several key issues proved to require further research to be able to provide definitive conclusions. Such research would have been out of scope and as such, simplified explanations and models were employed. The thesis concludes with a discussion of the practical implications of the proposed concept, including its application to cryptocurrencies and similar assets, and identifies potential areas for future research. financial instruments capital markets law product-neutral law and economics new institutional economics legal history comparative analysis regulatory framework financial innovation equity financial derivatives debt debt instruments pre-modern markets financial history legal evolution transferability negotiability international trade historical evolution cryptocurrencies fractional shares transactional costs transaction cost theory Coase behaviorism finansiella instrument kapitalmarknadsrätt produktneutralitet rättsekonomi ny institutionell ekonomi rättshistoria komparativ analys regulatoriskt ramverk finansiell innovation aktier finansiella derivatinstrument skuldfinansiering förmoderna marknader finansiell historia rättslig evolution överlåtbarhet negotiabilitet internationell handel historisk evolution kryptovalutor aktieandelar transaktionskostnader transaktionskostnadsteori Coase rättsekonomisk behaviorism Law Juridik
