We estimate a non-parametrical Capital Asset Pricing Model (CAPM) and find strong evidence rejecting the classical linear CAPM. Furthermore, we find inconsistent linear betas for a series of stocks in the Colombian stock exchange (BVC), supporting the hypothesis of a better and consistent...

Resumen: Este estudio tiene como finalidad evaluar la efectividad que variables tales como el tamaño de la firma y la relación del valor en libros a valor de mercado-presentes en el modelo de Fama y French-tienen para capturar el retorno esperado promedio de los activos, en comparación con...

Resumen: Se presenta una metodología reciente para la detección del contagio financiero basada en coeficientes de dependencia asintótica. Este enfoque, sin alejarse de las condiciones teóricas del problema, logra sortear las críticas estadísticas a las que frecuentemente están expuestas...

Understanding how price-volume information determines future price movement is important for market makers who frequently place orders on both buy and sell sides, and for traders to split meta-orders to reduce price impact. Given the complex non-linear nature of the problem, we consider the...

The pace of biodiversity loss requires drastic shifts in conservation efforts that carry substantial costs. We investigate how the financial market prices such conservation costs exploiting the "Green Shield Action," a major regulatory initiative launched by the Chinese central government in...

This paper examines the impact of transition and physical climate risk on stock markets using, for the first time in this context, the annual CCPI index calculated by Germanwatch as well as its components (in addition to a wide range of other indices) for 48 countries from 2007 to 2023....

This study provides new evidence on the impact of climate physical risk (as measured by the Global Climate Risk Index (CRI) from Germanwatch) on stock market returns. Specifically, a panel model with fixed effects is estimated using annual data from 2007 to 2021 for a set of 65 countries as well...

This paper investigates whether and how the COVID-19 pandemic affects bank funding costs in China. We find a significantly positive relationship between the offering yields of negotiable certificates of deposit and banks’ pandemic exposure. The surge in bank funding costs is alleviated by...

We document shifts in investor composition during quantitative tightening, which suggest that investors adjust their portfolios at different speeds. To understand its implications for bond valuation, we develop a general equilibrium model which highlights the dynamic interaction between...
