What (If Anything) is Wrong with High-Frequency Trading?
This essay examines three potential arguments against high-frequency trading and offers a qualified critique of the practice. In concrete terms, it examines a variant of high-frequency trading that is all about speed—low-latency trading—in light of moral issues surrounding arbitrage, information asymmetries, and systemic risk. The essay focuses on low-latency trading and the role of speed because it also aims to show that the commonly made assumption that speed in financial markets is morally neutral is wrong. For instance, speed is a necessary condition for low-latency trading’s potential to cause harm in “flash crashes.” On the other hand, it also plays a crucial role in a Lockean defense against low-latency trading being wasteful developed in this essay. Finally, this essay discusses the implications of these findings for related high-frequency trading techniques like futures arbitrage or latency arbitrage—as well as for an argument as to why quote stuffing is wrong. Overall, the qualifications offered in this essay act as a counterbalance to overblown claims about trading at high speeds being wrong.

The constitutional political economy of virtual worlds
In virtual worlds, a social order able to coordinate the actions of tens of thousands of people emerges in a non-predetermined but designed way. The central puzzle the developers of such worlds have to solve is the same political economists face: to establish a well-functioning set of rules allowing for the thriving of the regulated community. The purpose of this paper is to provide a discussion of the particularities of the constitutional political economy of virtual worlds: their institutions, the prevalent beliefs of the players, and their organizations. The main reason why we should care about doing research
on
virtual worlds is the huge potential for research
in
virtual worlds. Virtual worlds present a middle ground in the debate between the greater control of laboratory experiments and the higher external validity of the field. Besides being an important cultural phenomenon per se, they emerge as the researchers’ tool to conduct experiments on a truly social level with tens of thousands of subjects. To show the usefulness of such environments for research in political economy in an exemplary but concrete fashion, the paper also presents some findings difficult to be produced elsewhere: data on an astonishingly high percentage of altruistic behavior in a Hobbesian natural state drawn from a dictator game played online.

Spontaneous disorder: conflict-kindling institutions in virtual worlds
This paper analyses the emergence and persistence of disorder due to bellicose (i.e. ‘conflict-kindling’) institutions. It does so relying on a novel empirical approach, examining the predatory and productive interactions of 400,000 users of a virtual world as well as its institutions. The paper finds that while there are many cases of spontaneous order in that virtual world, and while the users are not more conflict-loving as such, bellicose institutions sanctioning suicidal attacks in a supposedly safe region spontaneously emerged and rigidly persist, thus upholding disorder (i.e. a particularly violent kind of ordered anarchy).
