This paper studies competitive allocations under adverse selection. We first provide a general necessary and sufficient condition for entry on an inactive market to be unprofitable. then use this result characterize, active market, unique budget-balanced allocation implemented by tariff making additional trades with entrant Motivated the recursive structure of allocation, we finally show that i...

The existing superstar model (Rosen, 1981) does not require imperfect substitutes, and the convexity of total earnings with respect to talent is due to greater output for those with more talent. Our model explains why wages would increase at an increasing rate in talent. Imperfect substitutability between non-superstars and superstars with probabilistic production results in convexity in wage r...

This paper pits neoclassical theory against prospect theory by investigating several clean tests of the competing hypotheses. Consistent with previous work, the field experimental data suggest that prospect theory adequately organizes behavior among inexperienced consumers, whereas consumers with intense market experience behave largely in accordance with neoclassical predictions. The data indi...

consumer behavior is the most important issues in microeconomics. in neoclassical economics it is assumed that in order to reach the goals, human behavior is based on absolute rationality. while, simon criticizes the paradigm assumptions of neoclassic school and introduces the bounded rationality. since, because of uncertainty and lack of access to enough information, human faces with limited c...

The purpose of this paper is to develop an output oriented methodology for calculating productivity growth by using Malmquist productivity index (MPI) and two different data envelopment analysis (DEA) views (optimistic and pessimistic) simultaneously, and apply it to five Iranian Commercial Banks over the four time period (2009-2013). Consequently, we have proposed a new approach called the dou...

JEL Classification Code(s): J 31, J 71) "Perceptions of Discrimination, Effort to Obtain Psychological Balance, and Relative Wages: Can We Infer a Happiness Gradient?" There is a substantial literature that finds a linkage between happiness and relative economic well being as measured by earnings or wages. There is also a well documented racial gap in wages. One explanation for this is disparat...

This paper studies competition between firms when consumers observe a private signal of their preferences over products. Within the class structures that induce pure-strategy pricing equilibria, we derive are optimal for and those consumers. The firm-optimal policy amplifies underlying product differentiation, thereby relaxing competition, while ensuring purchase preferred product, maximizing t...

We introduce a search model where products differ in horizontal attributes and unobserved quality (“experience goods”), firms can establish reputation. show that the inability of consumers to observe before purchase significantly changes how frictions affect market performance. In equilibrium, higher costs reduce match values increase price but boost firms’ investment product quality. Under pla...

Panel data on Ghanaian manufacturing firms are used to test predictions from models of irreversible investment under uncertainty. Information on the entrepreneur’s subjective probability distribution over future demand for the firm’s products is used to construct the expected variance of demand, which is used as a measure of uncertainty. Empirical results support the prediction that firms wait ...

The Net Present Value maximizing model has a respectable ancestry and is considered by most scholars a theoretically sound decision model. In real-life applications, decision makers use the NPV rule, but apply a subjectively determined hurdle rate, as opposed to the “correct” opportunity cost of capital. According to a heuristics-and-biases-program approach, this implies that the hurdle-rate ru...
