We develop a deep reinforcement learning (RL) framework for an optimal market-making (MM) trading problem, specifically focusing on price processes with semi-Markov and Hawkes Jump-Diffusion dynamics. We begin by discussing the basics of RL and the deep RL framework used; we deployed the...

This paper examines the dynamic relationships between speculative activities, commodity returns, and macroeconomic conditions across five sectors compassing 29 commodities. Using weekly data spanning from January 2000 to July 2023, we construct comprehensive measures of commodity market...

Situated atop condominium buildings, 'top floor units' (TFU) offer unparalleled views and privacy, courtesy of accessible roofs. This paper empirically examines this status symbol and finds that: (1) TFUs interact with the macroeconomy differently from ordinary units, (2) when considering the...

This paper employs the opening of the first international telegraph between London and Paris on 13 November 1851 as a unique event that enabled a virtually instantaneous information exchange between the largest financial centers. Before this opening, a London currency speculator comparing the...

This paper aims to assess the role of expectations as a determinant of the real price of natural gas. To measure expectations-driven speculative demand three approaches are followed, which are based respectively on using natural gas inventories consistently with the theory of storage (Kilian and...

This study investigates whether investors' overreactions to blockchain-related announcements is driven by corporate executive opportunism in the Chinese capital market. We manually collect blockchain-related announcements made by Chinese listed firms over 2016–2022 and conduct an event study...

The inflation surge in recent years is having profound social, economic, and political consequences. With food price changes being an integral part of inflation, low income segments of the population are strongly impacted. What makes this period so unusual is the breadth of price pressures that...

Higher order beliefs - beliefs about others' beliefs - may be important for trading behaviour and asset prices, but have received little systematic empirical examination. We study more than twenty years of evidence from the Robert Shiller Investor Confidence surveys, which directly elicit...

In a pre-registered laboratory asset market study, we investigate dynamics of asset markets with zero (or close to zero) fundamental values. We introduce the "greater fool asset market game" with a zero-value token, whose price doubles in each period. We design several treatments, which differ...

The objective of the study is to explore the motives of investors to invest in derivative markets. It is a quantitative study where a survey method was used to collect data from the investors using a probability sampling method. The data was analyzed using PLS-SEM to test the conceptual model....

This article reviews Paul Crosthwaite's Speculative Time: American Literature in an Age of Crisis (2024) and Liliana Doganova's Discounting the Future: The Ascendancy of a Political Technology (2024), situating them within recent scholarship on a future-oriented, speculative, and economic...

In this study, we investigate the dynamic relationship between return and liquidity in the Brent and the West Texas Intermediate (WTI) oil markets. The research utilises daily oil price and volume data and monthly macroeconomic data from January 1, 1996 to April 28, 2023 obtained from the Energy...

The present study investigates the relationship between innovation (INN) and foreign direct investment (FDI) attraction across 66 developing countries from 2013 to 2021. Adopting the Difference Generalized Method of Moments estimation, the study reveals a statistically positive INN-FDI nexus....

Using German and US brokerage data we find that investors are more likely to sell speculative stocks trading at a gain. Investors' gain realizations are monotonically increasing in a stock's speculativeness. This translates into a high disposition effect for speculative and a much lower...

Given that corporate managers use stock prices as signals when making investment decisions, does market manipulation distort this process and impact corporate investment? We find that the increased prevalence of stock price manipulation has an economically meaningful negative effect on firms’...

We compare the implications of speculation versus hedging channels for bond markets in heterogeneous agents’ economies. Treasuries command a significant risk premium when optimistic agents speculate by leveraging their positions using bonds. Disagreement drives a wedge between marginal agent...

Information asymmetry between buyers and sellers is often credited as the primary cause of speculation in trading markets. The advent of blockchain technology, which enables full transparency and equal access to trading information for all trading partners, is expected to eliminate information...

Futures market prices in different countries affect each other such is the case for US and China. China has a huge share of the global consumption of commodities and the Chinese government is concerned about the excessive influence of global speculative forces. Therefore, it is important to...

The validity of day trading as a long-term consistent and uncorrelated source of income for traders and investors has always been a matter of debate. In this paper, we investigate the profitability of the well-known Opening Range Breakout (ORB) strategy during the period of 2016 to 2023. This...

Using data with trader identities for all transactions in SENSEX-index stocks on the Bombay Stock Exchange over seven years, we identify individual day traders (IDT) to be “noise traders”, who play an important role in market microstructure models in the literature.IDT contribute 10% to...

Non-Fungible Tokens (NFTs) offer a unique opportunity to study market misconduct in an unregulated crowdfunding environment. This paper examines insider and wash trading in the NFT market using publicly accessible Ethereum blockchain data. Results reveal that insider purchases, particularly by...

This paper constructs speculative bubbles in a Real Business Cycle (RBC) economy. Building on Blanchard’s (Economics Letters, 1979) classic analysis of speculative bubbles in asset pricing models, the bubbles studied here result from the absence of a transversality condition for production...

Share buybacks are in many respects a socially desirable financial technique, and the tremendous majority of these operations is surrounded by adequate safeguards preventing any risk of improper implementation. Yet share buybacks may, in some circumstances, reflect market manipulation practices,...

Speculative news on corporate takeovers may hurt productivity because uncertainty and threat of job loss cause anxiety, distraction, and reduced collaboration and morale among employees and managers. Using a panel of OECD-headquartered firms, we show that firm productivity temporarily declines...
