Full textRecent empirical analyses have revealed the existence of the Zumbach effect. This discovery has led to the development of quadratic Hawkes processes, which are suitable for reproducing this effect. Since this model is not linked with the price formation process, we extended it to order book modeling with a generalized quadratic Hawkes process (GQ-Hawkes). Using market data, we showed that there is a Zumbach-like effect that decreases future liquidity. Microfounding the Zumbach effect, it is responsible for a destabilization of financial markets. Moreover, the exact calibration of a GQ-Hawkes process tells us that the markets are on the verge of criticality. This empirical evidence therefore prompted us to analyse an order-book model constructed upon a Zumbach-like feedback. We therefore introduced the quadratic Santa Fe model and proved numerically that there is a phase transition between a stable market and an unstable market subject to liquidity crises. Thanks to a finite size scaling we were able to determine the critical exponents of this transition, which appears to belong to a new universality class. As this was not analytically tractable, it led us to introduce simpler models to describe liquidity crises. Setting aside the microstructure of the order book, we obtain a class of spread models where we computed the critical parameters of their transitions. Even if these exponents are not those of the quadratic Santa Fe transition, these models open new horizons for modelling spread dynamics. One of them has a non-linear coupling that reveals a metastable state. This elegant alternative scenario does not need critical parameters to obtain an unstable market, even if the empirical evidence is not in its favour. Finally, we looked at the order book dynamics from another point of view: the reaction-diffusion one. We have modelled a liquidity that appears in the order book with a certain frequency. The resolution of this model at equilibrium reveals that there is a condition of stability on the parameters beyond which the order book empties completely, corresponding to a liquidity crisis. By calibrating it on market data we were able to qualitatively analyse the distance to this unstable region
Manco, Lopez Oscar Oswaldo. "Applied modelization of electricity markets as a financially unstable complex system." Thesis, Paris Est, 2016. http://www.theses.fr/2016PESC0055.
Full textThe challenges faced by different sectors of the economy, respond to the evolution and specialization of consumers and producers, where the needs are becoming more complex. In this sense, during the last 5 years the electricity markets have undergone an evolutionary pro- cess that aims to meet the needs of all stakeholders in the midst of sustainability scenarios.Thus, the agents involved in the electricity market, present a num- ber of exhibitions of operational nature, legal, ethical, financial, among others, which require a specialization allowing the entry of new tech- nologies. This research project focuses on the study of financial risk, which despite being so specific, consider many elements with the aim of ensuring the functioning of the market and its participants.In previous studies, some models have concentrated on the in- vestigation of blackouts phenomena, the stability of the network, the dynamic power system, and Smart grids, among others. Mean- while other investigations have addressed the problem of forecasting different variables like the spot price and corporate strategy, with the aim of increasing the profitability of the participants. Now, this project presents the proposal of a complex financial model, which results in calculating a market equilibrium considering initial condi- tions and risk constraints. Using game theory it demonstrates equi- librium instability and that through complexity it is possible to find an optimal scenario in terms of profitability for the system and the agents.In chapter 1 it carried out a review of previous studies in order to justify the investigation, then Chapter 2 includes a description of the Colombian electricity market, with different specifications. In chap- ter 3 the KRI are defined, and they will be integrated in Chapter 4 as a fundamental part of the comprehensive model. Finally, Chapter 5 includes the results of the study ending with some possible further studies and additional considerations

Full textThis thesis analyses and integrates theoretical arguments, from various research fields, supporting the existence of a causality link between financial liberalization and macroeconomic fluctuations. It presents theoretical arguments supporting the idea that financial liberalization exaggerates financial instability. It examines two components of financial instability: banking instability and market instability. First, it gives some theoretical arguments showing that the new organization of financial markets, partly due to financial liberalization, increased the importance and impact on prices of mimetic and other destabilizing behavior of traders, hence increased markets volatility. Secondly, it shows that financial liberalization, while enhancing competition between financial intermediaries, reduced banks traditional source of profit: interest margins. To compensate this loss of revenue, banks developed markets operations. Thus, their long run profitability may stay the same, but their results should become less stable. Greater fluctuations of banks results would be expected. So, financial liberalization must have increased financial instability (more volatile asset prices and greater fluctuations of banks results). Therefore, both demand and supply side of the credit market must have been affected. Thus, macroeconomic fluctuations should increase. This argument is supported by the results of the simulations of a macro financial cycle model

Full textSince 1996 in order to fight inflation, Haiti put in place a monetary policy targeting money supply with inflation target. Inflation high gets started from budget deficit accumulation and monetary financing by seigniorage. This practice of financing by inflationary taxes implies a problem of credibility of monetary policy even with a double monetary circulation and a dollarization of the economy reaching 50% since 2004. The monetary policy implementation aims to avoid inflation bias and different approaches for improving credibility has been considered. The economic crisis started in 2007 created by the instability of the financial markets, forced the establishment of non-conventional monetary policy to avoid the liquidity trap. This crisis has resulted in an accumulation of international reserves and low interest rate in emerging economies and the economies of underdeveloped countries. It became more and more evident that the theoretical basis of the monetary policy strategy remains looking for both, monetary stability and the stability of the financial markets, in order to maintain the credibility and efficiency of the monetary policy of central banks. The misuse made by the FED in the USA of quantitative easing, rise concerns about a crisis of sovereign debt of the Sates, the creation of speculative bubble, and a possible return to the recession. With the case of Haiti, the expectations are not rationales because of forecast errors. A joint analysis of banks interests’ rates using a VECM model has not enabled us to find a long run equilibrium rate between them. The Seo test concluded that chocks affect the dynamic of both rates. The agreements with the IMF allowed improving weakly the monetary policy efficiency with the accumulation of international reserves in the wake of the crisis which started in 2007

Full textDans cette thèse, nous nous sommes intéressés aux raisons pouvant expliquer les résultats ambigus des études appliquées sur le lien entre le développement financier et la croissance. En premier lieu, nous considérons que le développement financier risque d'être simultanément une source d'instabilité financière de telle sorte que l'effet bénéfique du développement financier sur la croissance soit amoindri ; il nous paraît donc indispensable de prendre en compte ce lien entre le développement financier et l'instabilité financière pour pouvoir véritablement apprécier la contribution du développement financier à la croissance. En second lieu, nous considérons l'existence d'effets de seuil dans la relation entre le développement financier et la croissance. En effet, il se peut qu'il existe un seuil minimum de développement économique en dessous duquel le développement financier n'a pas d'impact significatif sur la croissance, principalement à cause de la faiblesse de l'épargne et de la rentabilité des investissements. Par ailleurs, étant donné que la littérature économique s'est beaucoup consacrée à la relation entre le développement financier et la croissance, et très peu à la relation entre le développement financier et la réduction de la pauvreté, nous nous sommes également intéressés à l'impact spécifique que le développement financier peut avoir sur la réduction de la pauvreté au-delà de son effet indirect qui passe par la croissance.
L'analyse économétrique effectuée sur un panel de pays en développement avec des données quinquennales sur la période 1966-2000 nous a permis de mettre en évidence une relation positive entre le niveau de développement financier et celui de l'instabilité financière ; en particulier, l'instabilité du niveau de développement financier et l'occurrence de crises bancaires s'accroissent avec le développement du système financier. Les résultats montrent également que l'instabilité financière a un effet négatif sur la croissance économique et qu'elle réduit l'impact favorable du développement financier sur la croissance sans toutefois l'annuler. Par ailleurs, il ressort de notre analyse que pour les pays dont le niveau de PIB par tête est inférieur à un seuil de 2560 dollars, le développement financier ne semble pas avoir d'impact significatif sur la croissance. L'existence des effets de seuil et la prise en compte de l'instabilité financière dans la relation entre le développement financier et la croissance constituent des hypothèses complémentaires permettant d'expliquer les résultats ambigus des études appliquées sur le lien entre le développement financier et la croissance. Enfin, notre analyse montre également qu'en plus de son effet à travers la croissance, le développement financier favorise la réduction de la pauvreté principalement grâce à l'effet de conduit du capital de McKinnon (1973), l'accès aux dépôts profitent plus aux pauvres que l'accès aux crédits.
Intrator, Hélène. "Recherche sur la volatilité et l'instabilité financières." Paris 1, 1992. http://www.theses.fr/1992PA010003.
Full textDefined as unpredictable, also supposing risk, volatility suggests the incontrolability of developments, and is linked to the way the system fits, or instantly reacts to uncertainty. A permanent state seems to be its other characteristic. Since the 1980's, it has never kept being more or less present on the evolution of variables. Instability is refering to a dynamic interpretation of systems, passing from a balance to an other one. Far from being but an evidence of instability, volatility can be regarded as a stable phenomenon within the financial system. The chaos theory argues for this view. The aim of this thesis will have been to demonstrate that financial volatility calls into questions the existing theories which are denying the uncertainty of systems. The demonstration of this idea is laying on information resuming methods (such as principal component analysis), and conditional modeling techniques (as A. R. C. H. Models). Consequences of volatility upon economical agents are carefully studied. The main beneficiaries are the big firms, but the new patrimonial behaviour of households is making the decrease in the saving rate, significantly relative. At last, the coordination of policies and the integration of markets are trying to check volatility at an international level
