Cross-correlation Measures in the High-frequency Domain

Abstract

On a high-frequency scale the time series are not homogeneous, therefore standard correlation measures cannot be directly applied to the raw data. To deal with this problem the time series have to be either homogenized through interpolation, or methods that can handle raw non-synchronous time series need to be employed. This paper compares two traditional methods that use interpolation with an alternative method applied directly to the actual time series. The three methods are tested on simulated data and actual trades time series.

Is psychology of money a gendered affair? A scoping review and research agenda

The study of gender differences in the financial domain is gaining increasing attention as evidenced by the UN 2030 Agenda for Sustainable Development. Previous research has highlighted the existence of a gender divide in many economic issues; however, there is still a lack of comprehensive understanding of the psychological aspects of money management. This systematic scoping review aims to fill this gap by outlining gender differences in money attitudes and money management practices, adopting the Scientific Procedures and Rationales for Systematic Literature Reviews protocol as methodological guideline. An extensive analytical strategy was employed on Scopus, Web of Science, PsycINFO, and EconLit to identify 100 empirical papers on the topic, published between 1972 and 2021. The analysis revealed clear differences in how men and women approach to money from a symbolic and attitudinal perspective, whereas evidence of money management practices is more complex and sometimes conflicting. Men and women hold different conceptions of money, with men often looking at it as a symbol of success and power and women holding more ambivalent attitudes toward money as both a source of anxiety and a means to ensure security and prove their love. As far as for financial behaviors studies indicate that both genders have similar approaches to savings and expenses monitoring, while financial investments are primarily pursued by men. Future directions and suggestions for private and public institutions are discussed, highlighting research advancements and implications for gender empowerment programs and customized communications.

Lifting You up or Dragging You Down? The Role of Financial Inclusion in Poverty Transitions Among Italian Households

We estimate the effect of financial inclusion on transition probabilities into/out of poverty. By exploiting a longitudinal sample of Italian households between 2002 and 2016, we find that financial inclusion is effective in both reducing the likelihood of entering poverty and helping the poor to climb out of it. According to our estimates, access to deposit accounts reduces the risk of falling below the poverty line by 2.7 percentage points (pp) and increases the chance of exiting poverty by 4.4 pp. Significance and magnitude of such effects are confirmed when considering different poverty thresholds and definitions, alternative proxies for financial inclusion as well as alternative empirical strategies.     

Towards an open innovation ecosystem in the cultural industry: The bright side of trust and the dark side of measurement

The concept of open innovation ecosystems is receiving increasing attention in academic literature, but its application to the cultural industries and, more specifically, to philanthropically-funded cultural initiatives, remains a largely unexplored domain. This study, leveraging on in-depth interviews with stakeholders, observation and immersion in the field, employs primary qualitative data from a philanthropically-funded cultural initiative and applies the ecosystem-as-structure conceptual framework to study the factors that have enabled a nascent open innovation ecosystem in the cultural industries to emerge. Findings point to a number of essential components and characteristics of the emergent ecosystem that are crucial elements of success in the view of key stakeholders. The findings consequently shed light on the managerial practices and strategy that facilitate the success of a philanthropically-funded artistic initiative which fosters the creation of a new open innovation arts ecosystem.
