The limit order book on different time scales
2007
Financial markets can be described on several time scales. We use data from the limit order book of the London Stock Exchange (LSE) to compare how the fluctuation dominated microstructure crosses over to a more systematic global behavior.
Tick size and price diffusion
2010
A tick size is the smallest increment of a security price. It is clear that at the shortest time scale on which individual orders are placed the tick size has a major role which affects where limit orders can be placed, the bid-ask spread, etc. This is the realm of market microstructure and there is a vast literature on the role of tick size on market microstructure. However, tick size can also affect price properties at longer time scales, and relatively less is known about the effect of tick size on the statistical properties of prices. The present paper is divided in two parts. In the first we review the effect of tick size change on the market microstructure and the diffusion properties…
Using the Scaling Analysis to Characterize Financial Markets
2003
We empirically analyze the scaling properties of daily Foreign Exchange rates, Stock Market indices and Bond futures across different financial markets. We study the scaling behaviour of the time series by using a generalized Hurst exponent approach. We verify the robustness of this approach and we compare the results with the scaling properties in the frequency-domain. We find evidence of deviations from the pure Brownian motion behavior. We show that these deviations are associated with characteristics of the specific markets and they can be, therefore, used to distinguish the different degrees of development of the markets.
Levels of complexity in financial markets
2001
We consider different levels of complexity which are observed in the empirical investigation of financial time series. We discuss recent empirical and theoretical work showing that statistical properties of financial time series are rather complex under several ways. Specifically, they are complex with respect to their (i) temporal and (ii) ensemble properties. Moreover, the ensemble return properties show a behavior which is specific to the nature of the trading day reflecting if it is a normal or an extreme trading day.
The evolution of market power in European banking
2017
This paper analyses the effect that European financial market integration has had on the evolution of the banks' market power disparities. The results show that market power disparity has narrowed among eurozone banks. The reduction is attributable to the convergence in the average levels of market power of the European banking sectors. In contrast, the disparities observed within each country have remained stable. As a result, the measures adopted to advance towards a single banking market should be complemented by measures at the national level designed to intensify competition among the banks within a given country.
Like it or not? How the economic and institutional environment shapes individual attitudes towards multinational enterprises
2018
The integration of goods and factor markets has affected the lives of individuals all over the world. While some agents have reaped enormous benefits from this process, others have lost in terms of income and welfare. It is usually argued that individuals are aware of the distributional effects of globalization, and that this knowledge shapes their preferences over various policy issues such as protection, financial market regulation etc. In this chapter, we use a large surveybased data set to explore whether this conjecture is correct when it comes to individuals’ attitudes towards multinational enterprises (MNEs).
How markets slowly digest changes in supply and demand
2008
In this article we revisit the classic problem of tatonnement in price formation from a microstructure point of view, reviewing a recent body of theoretical and empirical work explaining how fluctuations in supply and demand are slowly incorporated into prices. Because revealed market liquidity is extremely low, large orders to buy or sell can only be traded incrementally, over periods of time as long as months. As a result order flow is a highly persistent long-memory process. Maintaining compatibility with market efficiency has profound consequences on price formation, on the dynamics of liquidity, and on the nature of impact. We review a body of theory that makes detailed quantitative pr…
New Approaches to Regulating the Activities of Rating Agencies: A Comparative Analysis
2016
Abstract Rating agencies have become an important part of the global financial landscape. Formation of credit ratings is specified by the inherent asymmetry of financial market information and general interest in the transformation of a large amount of diverse and segmented financial information in a simple and clear assessment of the credit surveillance of borrowers that is credit rating. The world financial crisis started in 2008 has again put on the agenda the question of rating assessment accuracy and the factors influencing the rating migration. The activity of rating agencies, until recently, has had little regulation, allowing rating agencies to avoid responsibility for inaccuracies …
Emergence of Statistically Validated Financial Intraday Lead-Lag Relationships
2014
According to the leading models in modern finance, the presence of intraday lead-lag relationships between financial assets is negligible in efficient markets. With the advance of technology, however, markets have become more sophisticated. To determine whether this has resulted in an improved market efficiency, we investigate whether statistically significant lagged correlation relationships exist in financial markets. We introduce a numerical method to statistically validate links in correlation-based networks, and employ our method to study lagged correlation networks of equity returns in financial markets. Crucially, our statistical validation of lead-lag relationships accounts for mult…
Credit Risk Disclosure Practices in the Annual Financial Reporting of Large Italian Banks
2019
Risk disclosure in banking is particularly important for the efficacy of market discipline, the assessment of bank performance, the efficiency of the financial market, and the overall stability of the financial system. The European banking union and the financial crisis have enhanced the strategic role of credit risk disclosure in banking. The topic of this chapter is the evaluation of credit risk disclosure practices in banks’ annual financial reporting. The empirical research is conducted on a sample of ten large Italian banks. The authors employ content analysis and provide a hybrid scoring model for the assessment of credit risk disclosure. The chapter provides empirical findings which …
