ider trading with penalties\, entropy and quadratic BSDEs\n\n\nAbstract: Ky
le model in continuous time where the insider may be subject to legal penal
ties is considered. The equilibrium is characterized via a backward stochas
tic differential equation (BSDE) whose terminal condition is determined as
the fixed point of a non-linear operator in equilibrium. In particular\, th
e solution reveals an interesting connection between h-transformations and
quadratic BSDEs.\n\nThe model finds that the insiders trade the same consta
nt multiple of the difference between their private signal and their expect
ation of the market price right before the private information becomes publ
ic\, which is in agreement with the recent empirical studies on insider tra
ding. Moreover\, the model is applied to the optimization problem of a regu
lator with the objective of deterring insider trading while ensuring that t
he prices are informationally efficient. It is shown that the optimal penal
ty policy is reduced to choosing from one of two extremal penalty levels th
at correspond to high and low liquidity regimes. The optimal choice is then
determined by the amount of noise trading and the relative importance of p
rice informativeness.
