In many areas across Siberia, the reindeer herding economy of the native people went into a deep recession during the post-Soviet transition of the 1990s. However, as a larger cross-section of data indicates, the reindeer stock decline is not a universal phenomenon. Nor is the present-day crisis in native Siberian herding economies an unprecedented event, as pastoralists did suffer tremendously...

• We assess herding in conventional cryptocurrencies, NFT and DeFi digital assets; No evidence of static herding; Time-varying is identified cryptocurrencies markets exhibit only during low volatility days; Cryptocurrency bubble 2021 has not amplified herding. examine the time-varying behavior three cryptocurrency classes: ‘conventional’ non-fungible tokens, assets most recent 2021. While analy...

The recently discovered two-phase phenomenon in financial markets [Nature 421, 130 (2003)] is examined with the German financial index DAX, minority games, and dynamic herding models. It is observed that the two-phase phenomenon is an important characteristic of financial dynamics, independent of volatility clustering. An interacting herding model correctly produces the two-phase phenomenon.

We look into determinants (volatility, crises, sentiment and the U.S. ‘fear’ index) of herding using BRICS as our sample. Investors herd selectively to crises is a short-lived phenomenon. Herding was highest during global financial crisis (only China affected). There no European debt COVID. With regard relationship between volatility CSAD (cross sectional absolute deviation)/herding, lower (mov...

BACKGROUND China has become the world's second largest healthcare market based on a recent report by the World Health Organization. Eventhough China achieved universal health insurance coverage in 2011, representing the largest expansion of insurance coverage in human history achieved; health inequality remains endemic in China. Lessons from the effect of market crisis on health equity in Europ...

We analyze some voting models mimicking online evaluation systems intended to reduce the information overload. The minimum number of operations needed for a system to be effective is analytically estimated. When herding effects are present, linear preferential attachment marks a transition between trustful and biased reputations.

A model is developed which implies that if an analyst has high reputation or low ability, or if there is strong public information that is inconsistent with the analyst's private information, she is likely to herd. Herding is also common when informative private signals are positively correlated across analysts. The model is tested using data from analysts who publish investment newsletters. Co...

This paper proposes a bridge between the Herding literature and the literature on Rational Expectations under asymmetric information. In particular we examine how the presence of discrete investment decisions affects the properties of a market equilibrium where information is costly to acquire. We choose to focus on the case where individual decisions are discrete since this appears to be the k...

We study intentional herding in investment styles by mutual funds, and its consequences. find that style is significant persistent. Herding tends to increase after periods of high market volatility decrease with sentiment, consistent the character herding. Furthermore, we related changes dynamics. Finally, certain temporarily funds’ performance, whereas it reduces flows. Overall, results illust...
