RELEVANCE OF CORPORATE SOCIAL RESPONSIBILITY INDICATORS FOR MEASURING FINANCIAL PERFORMANCE
2013
Clarifying the impact of corporate social responsibility on the economic and/or financial performance of the firm has been the subject of numerous studies, which focus on the nature of the interaction between the ability of companies to achieve a high level of corporate social responsibility on the one hand, and financial performance, on the other. The paper aims to contribute to the literature in this field by studying the relevance of stock exchange indexes built on the principles of corporate social responsibility as a tool to measure the financial performance of firms that adopt corporate social responsibility as manner of approach to business.
Skewness in financial returns
1999
Abstract In this paper the symmetry of daily returns is addressed in eight international stock markets and three spot exchange rates. Tests of symmetry with the sample skewness seem of little value, due to the non-normality of the returns. Under alternative non-normal distributions, the symmetry of the returns cannot be rejected for most markets. Distribution-free procedures do not detect strong asymmetries in most of the series either; however, some differences between returns below the mean and returns over the mean are observed in several markets
A new fuzzy logic controller for trading on the stock market
2007
A common problem that financia l operators often meet in their own work is to make, at the right moment, the operational choices on the Stock Market. Once the Market to act on has been chosen, the financial operator has to decide when and how to operate on it, in order to achieve a profit . The problem that we are going to deal with is the planning of an automatic decisional system for the management of long positions on bull market. First, a trading system (TS) will be im plemented pointing its features out. Then a fuzzy logic implementation of the TS will be introduced (FTS). The fuzzy system will be optimized by the genetic algorithms. Finally, the two different implementations of the tr…
Autonomous Operation of Stationary Battery Energy Storage Systems—Optimal Storage Design and Economic Potential
2021
Global warming requires a changeover from fossil fuel based to renewable energy sources on the electrical supply side and electrification of the demand side. Due to the transient nature of renewables and fluctuating demand, buffer capacities are necessary to compensate for supply/demand imbalances. Battery energy storage systems are promising. However, the initial costs are high. Repurposing electric vehicle batteries can reduce initial costs. Further, storage design optimization could significantly improve costs. Therefore, a battery control algorithm was developed, and a simulation study was performed to identify the optimal storage design and its economic potential. The algorithm used is…
Lionello Perera: An Italian Banker and Patron in New York
2022
The book presents the long-lost biography of Lionello Perera, principal banker, patron, and philanthropist of the Italian American community in New York at the inception of the twentieth century.

Financial crises in Spain: lessons from the last 150 years
2012
Financial crises are not unique to current financial systems. Are crises alike? Have they become more frequent, longer lasting and more severe since the 20th century? What does history tell us? The objective of this paper is to study the financial crises that have occurred in Spain over the last 150 years. We consider different types of crises (banking, currency and stock market crises), together with all their possible combinations, estimate their frequency by period and measure their length and depth. The main conclusion we obtain is that Spanish crises have been more frequent than in the rest of the world and have been more severe and more complex since 1973, as the 2007 crisis is confir…
Bubbles in China
2010
This study examines rational bubbles in Chinese stock markets and China-related share indices in Hong Kong. A duration dependence test is employed for both monthly and weekly abnormal market returns of the Shanghai and Shenzhen A- and B-markets, as well as for the Hong Kong China Enterprises and China Affiliated Corporations indices. The test results are mixed, as weekly data demonstrate bubbles for all of the Mainland Chinese stock markets, but monthly data do not show bubbles for any of the examined markets. Neither of the datasets indicates bubbles in the Hong Kong markets. Results indicate that, in terms of bubbles, segmentation does not play a significant role in bubble existence and t…
Romanian Equity Investments and Currency Risk: A Euro-Based Perspective
2021
Abstract This paper assesses the benefits and risks of international investments made on the Romanian stock market, from the perspective of euro-based investors. We investigate the contribution of exchange rate volatility to the total risk of these investments over a period of nine years, between January 2011 and December 2019, by using monthly values for the exchange rate between the Romanian leu and Euro and monthly values of the Romanian stock index. Our findings indicate that, on average, Romanian leu depreciated against euro, causing currency losses for the euro-based investor, counterbalanced by the Romanian index mean return, higher than euro countries index mean return during the pe…
