Despite recent studies focused on comparing the dynamics of market efficiency between Bitcoin and other traditional assets, there is a lack of knowledge about whether Bitcoin and emerging markets efficiency behave similarly. This paper aims to compare the market efficiency dynamics between...

This paper investigates whether short-term momentum and long-term reversal may emerge from the wealth reallocation process taking place in speculative markets. We assume that there are two classes of investors who trade long-lived assets by holding constantly rebalanced portfolios based on their...

A popular interpretation of the Rational Expectations/Efficient Markets hypothesis states that, if the hypothesis holds, then market valuations must follow a random walk. This postulate has frequently been criticized on the basis of empirical evidence. Yet the assertion itself incurs what we...

In this paper, we introduce a Transactionally Efficient Market Model, which evolves from the standard efficient market model, encompassing both transaction costs and bid-ask prices. Hence, we delve into how arbitrage makes its way within this complex setting. The main outgrowth of the analysis...

In this paper, I examine the impact of market inefficiency on the properties of implied cost of capital (ICC) estimates. I show that market inefficiency will bias the relation between the ICC estimate and future returns upwards. Utilizing recently developed ICC estimates formed using regression...

We consider a model where investors can invest directly or search for an asset manager, information about assets is costly, and managers charge an endogenous fee. The efficiency of asset prices is linked to the efficiency of the asset management market: if investors can find managers more...

We model 73.62 million London Stock Exchange (LSE) trades and show that the LSE's high rate of failure to open at the opening auction only relates to low volume stocks. Low volume stock traders avoid trading until the open; this seems connected to their evading the informed trading-dominated...

We examine the world's largest carbon exchange, ICE's ECX, by applying Chordia et al.'s (2008) conception of short-horizon return predictability as an inverse indicator of market efficiency. We find a strong relationship between liquidity and market efficiency such that when spreads narrow,...

We derive invariance relationships in a dynamic, infinite-horizon, equilibrium model of adverse selection with risk-neutral informed traders, noise traders, market makers, and with endogenous information production. The model solution depends on two state variables: stock price and...

Stock prices following earnings announcements have become more efficient. Prices on announcement dates incorporate more quickly earnings surprises, leading to the disappearance of post-announcement price drifts. Evidence suggests that trading frictions commonly associated with market...
