The well-known approximation of the difference between the arithmetic average and geometric average returns as one-half of the variance of the underlying returns is reexamined using Jensen's Inequality. The "defect" in Jensen's Inequality, is given an exlicit formula in terms of the variance...

Does machine learning and AI ensure that social biases thrive ? This paper aims to analyse this issue. Indeed, as algorithms are informed by data, if these are corrupted, from a social bias perspective, good machine learning algorithms would learn from the data provided and reverberate the...

This study investigates if market risk-based capital requirements (MRR) implemented in 1998 mitigated bank risk associated with trading activities. Recognizing that only banks with sufficiently high trading activities are subject to the MRR (regulated), we implement a difference-in-difference...

Financial institutions commonly face the risk that large trades will execute at unfavorable prices due to price impact effects from insufficient market liquidity. A typical method to manage these price impact effects is to split a given order into smaller pieces and to trade these pieces...

This paper discusses the concept of leverage, its components and how to measure and monitor it. It proposes an innovative approach to assessing leverage based on flows using the concept of a marginal leverage ratio, which reveals the leverage related to new activities, as a valuable supplement...

The history of banking provides a view that banks are often a liability to stable economies and their behavior can promote inequality, especially when they are involved in imprudent manipulation of credit and money and require government bailouts. What is the future of capitalism without banks,...

In this study, we examine the interplay between public environmental enforcement and private lender monitoring and its effects on borrowers’ environmental activities. To capture lender environmental monitoring, we use environmental covenants in loan agreements that require borrowers to take...

We model aggregate loss rates on credit portfolios dynamically using a default intensity approach. The default intensity we employ is allowed to depend on both observable macroeconomic variables and unobserved frailties. We use the model to extract measures of the credit cycle from US bank...

In this paper, we present two stylized models of the financial system. We make the case that in order to realize the potential of a well-functioning complete financial market, financial system designers and financial service providers will need to think about ways to deliver financial...

The low level participation of the Islamic banks in mudharabah and musharakah financing models has become one of the problems in the development of the industry. This arrangements are unique to Islamic banking and account for its superiority over conventional banking on grounds of ethics and...
