This paper extends the classic factor-based asset pricing model by including network linkages in linear factor models. We assume that the network linkages are exogenously provided. This extension of the model allows a better understanding of the causes of systematic risk and shows that (i)...

By employing a dynamic model with two limit order books, we show that fragmentation is associated with reduced competition among liquidity suppliers and lower picking-off risk of limit orders. Due to these countervailing channels, the impact of fragmentation on liquidity and welfare differs with...

We identify a component of monetary policy news that is extracted from high-frequency changes in risky asset prices. These surprises, which we call "risk shifts", are uncorrelated, and therefore complementary, to risk-free rate surprises. We show that (i) risk shifts capture the lion's share of...

We define a sentiment indicator based on option prices, valuation ratios and interest rates. The indicator can be interpreted as a lower bound on the expected growth in fundamentals that a rational investor would have to perceive in order to be happy to hold the market. The lower bound was...

Numerous empirical studies have demonstrated that asset prices react rapidly, if at all, to news published in the mass media. In many cases, the information has been discounted and prices have already moved upon primary publication through news wires, press releases or firm announcements. Any...

The modelling of financial markets presents a problem which is both theoretically challenging and practically important. The theoretical aspects concern the issue of market efficiency which may even have political implications, whilst the practical side of the problem has clear relevance to...

The need to develop securities market has, following the recent international financial crises, increasingly attracted the attention of national and international policy makers. Never before have developed and developing countries shared such a strong interest in ensuring the stable growth of...

Existe un diferencial entre el valor de mercado del patrimonio y el valor contable. Este se relaciona a los activos intangibles. Un análisis de regresión, permite concluir que el retorno total al inversor, la rentabilidad sobre activos y las utilidades totales, en conjunto con alguna (todas...

EXTRACTO: El objetivo de esta investigación es contrastar las dos metodologías que han sido utilizadas normalmente para el cálculo de beta de mercado. Ellas son: la “tradicional” propuesta por Black, Jensen y Scholes (1972) y por Fama y MacBeth (1973); y la denominada “impar-par”...

This article studies the relative investment performance of several stock-valuation measures. The first is mispricing based on the valuation model developed by Bakshe and Chen (1998)and extended by Dong (1998) (hereafter, the BCD model). The BCD model relates, in closed form, a stock's fair...
