This is the first paper that explores lottery-like demand in cryptocurrency markets. Since recent research provides evidence that cryptocurrency returns are rather short-memory processes in their nature, we modify Bali et al.'s (2011, 2017) MAX measure and employ a weekly forecast horizon and...

Currency and financial turmoils in international capital markets have been the focus of an extensive theoretical research which started around 30 years ago. This paper provides a synthetic overview of this theoretical modeling. We analyze the basic analytical framework corresponding to the...

We present a dynamic Rational Expectations (RE) bubble model of prices with the intention to evaluate it on optimal investment strategies applied to Bitcoin. Our bubble model is defined as a geometric Brownian motion combined with separate crash (and rally) discrete jump distributions associated...

We unite investment by speculators and tech-savvy investors with a heterogeneous agent model.While speculators seek to profit from extrapolating the price trends, tech-savvy investors trade based on the prospective value of Bitcoin, which is a function of factors that capture the market demand...

This paper studies how the interaction between policy maker's reputation for defending against speculative attacks and speculators' learning of the policy maker's type determines the emergence of speculative attacks and the outcome of regime change. If speculators receive conditionally...

I examine the profitability of three simple foreign exchange technical trading rules (moving average, momentum, and relative strength index) before, during and after the 2007-2008 global financial crisis. The overall findings reveal that these technical indicators could produce statistically...

We investigate the effects of different regulatory policies directed towards high-frequency trading (HFT) through an agent-based model of a limit order book able to generate flash crashes as the result of the interactions between low- and high-frequency (HF) traders. We analyze the impact of the...

We develop a parsimonious model of bubbles based on the assumption of imprecisely known market depth. In a speculative bubble, traders drive the price above its fundamental value in a dynamic way, driven by rational expectations about future price developments. At a previously unknown date, the...
