متن کاملAgency Models with Frequent Actions: A Quadratic Approximation Method
The paper analyzes dynamic principal-agent models with short period lengths. The two main contributions are: (i) an analytic characterization of the values of optimal contracts in the limit as the period length goes to 0, and (ii) the construction of relatively simple (almost) optimal contracts for _xed period lengths. Our setting is exible and includes the pure hidden action or pure hidden inf...
متن کاملRelativistic Stellar Models with Quadratic Equation of State
In this paper, we have obtained and presented new relativistic stellar configurations considering an anisotropic fluid distribution with a charge distribution and a gravitational potential Z(x) that depends on an adjustable parameter. The quadratic equation of state based on Feroze and Siddiqui viewpoint is used for the matter distribution. The new solutions can be written in terms of elementar...
متن کاملOnline Appendix for “Agency Models with Frequent Actions: A Quadratic Approximation Method”
Lemma 17 Suppose that Θ(ā, h̄ ≥ θ > 0 for all ā > 0. (i) For any initial conditions F (w) and F ′(w) the HJB equation (3) has a unique solution F in any interval [w, w̄] ⊂ R. (ii) F is twice continuously differentiable and (F, F ′) depends continuously on the initial conditions. (iii) F ′ is monotone with respect to F ′(w). That is, if F1 and F2 are two solutions of the HJB equation in an interva...

The paper analyzes dynamic principal-agent models with short period lengths. The two main contributions are: (i) an analytic characterization of the values of optimal contracts in the limit as the period length goes to 0, and (ii) the construction of relatively simple (almost) optimal contracts for fixed period lengths. Our setting is flexible and includes the pure hidden action or pure hidden ...
