sensitivity analysis with respect to the functional forms provides estimates of the uncertainties involved in choosing a specific functional structure. this is vital in cge modeling where it is conventional to take elasticities from other studies. in the present study, the robustness of model results with respect to the functional form is checked. in one scenario, the production function is rep...

firm size and its impact on the firm performance examined in all of economics historical periods from different point of view. meanwhile, productivity is one the most important performance index for each firm, therefore so many studies tries to survey firm size impact on it. in iran also, economics literature replete with productivity studies but the impact of size on it rarely seen between the...

I study the optimal supply of ‡exible commitment devices to people who value both commitment and ‡exibility, and whose preferences exhibit varying degrees of time inconsistency. I …nd that, if time inconsistency is observable, then both a monopolist and a planner supply devices that enable each person to commit to the e¢ cient level of ‡exibility. If instead time inconsistency is unobservable, ...

This paper develops a model of nonlinear pricing with competition. The novel element is that each consumer’s willingness to pay for quality is private information and is allowed to di¤er across brands. The consumer’s preferences are represented by a multidimensional type containing the marginal value of quality for di¤erent products. Buyers with high willingness to pay for quality also display ...
