The model examines a policy space <math>x\in[-0.5,0.5]R</math> and a lobbyist's efforts to bribe legislators to adopt a policy near his ideal point. The lobbyist's utility function is <math>u(x,B)=-(x-L)^{2}</math>, where x is the policy chosen, L is the lobbyist's ideal point and B is the total number of bribes paid to legislators. The lobbyist is assumed to have an infinite budget.
