We develop a theoretical model of a network of intermediaries, which gives rise to heterogeneous financial norms and systemic vulnerabilities. The optimal behavior of each intermediary regarding its attitude toward risk, the quality of the projects that it undertakes, and the intermediaries it chooses to interact with, is affected by the behavior of its counterparties. These strategic network e...

We estimate firms’ cash flow sensitivity of cash to empirically test how the financial system’s structure and activity level influence their financial constraints. For this purpose we merge Almeida et al. (2004), a path-breaking design for evaluating a firm’s financial constraints, with Levine (2002), who paved the way for comparative analysis of financial systems around the world. We conjectur...

Information is fundamental to Finance, and understanding how it flows from official sources to news agencies is a central problem. Readers need to digest information rapidly from high volume news feeds, which often contain duplicate and irrelevant stories, to gain a competitive advantage. We propose a text categorisation task over pairs of official announcements and news stories to identify whe...

In this paper we consider an extension of the Sparre Andersen insurance risk model by relaxing one of its independence assumptions. The newly proposed dependence structure is introduced through the premise that the joint distribution of the interclaim time and the subsequent claim size is bivariate phase-type (see, e.g. Assaf et al. (1984) and Kulkarni (1989)). Relying on the existing connectio...

This article examines the extent of derivative financial instrument use among US nonprofit health systems and the impact of these financial instruments on their cash flows, reported operating results, and financial risks.

Organizational risk is often defined as a change in the flow of profit, or as a sys-tematic or non-systematic changes in the stock return flow. The risk taking of management is conceptualized as the actual investment decisions that are indictors due to uncertainty results. The purpose of this study is to investigate the effect of financial characteristics on future corporate risk taking behavio...
