The tracking control of linear differential inclusions with stochastic disturbance is considered. The feedback law is constructed by the convex hull Lyapunov function. The design objective is to make the error system uniformly ultimately bounded in mean square. Finally, a numerical simulation is...

We examine the impact of social ties between mutual fund managers and auditors of public firms on mutual fund stockholdings. We find that mutual funds whose managers are socially connected with firm auditors hold more shares of these firms. In cross-sectional results consistent with...
