The compiled record

The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. Numbers in the tables are the authors', checked by code. No sentence in this record was written by a model.

The abstract, sentence by sentence

arXiv listing abstract v1. Results and the main claim are underlined; .

This study investigates the prevention of market manipulation using a price-impact model of financial market trading as a linear system. First, I define a trading game between speculators such that they implement a manipulation trading strategy that exploits momentum traders. Second, I identify market intervention by a controller (e.g., a central bank) with a control of the system. The main result shows that there is a control strategy that prevents market manipulation as a subgame perfect equilibrium outcome of the trading game. On the equilibrium path, no intervention is realized. This study also characterizes the set of manipulation-proof linear pricing rules of the system. The set is very restrictive if there is no control, while the presence of control drastically expands the set.

The paper
Original abstract

This study investigates the prevention of market manipulation using a price-impact model of financial market trading as a linear system. First, I define a trading game between speculators such that they implement a manipulation trading strategy that exploits momentum traders. Second, I identify market intervention by a controller (e.g., a central bank) with a control of the system. The main result shows that there is a control strategy that prevents market manipulation as a subgame perfect equilibrium outcome of the trading game. On the equilibrium path, no intervention is realized. This study also characterizes the set of manipulation-proof linear pricing rules of the system. The set is very restrictive if there is no control, while the presence of control drastically expands the set.
