(3 points)Suppose there are three types of economies as follows:

Economy A: Both workers and employers have perfect information (i.e., workers perfectly know all of the available jobs in the economy and employers perfectly know all of the available workers in the economy as well as their productivity). In this economy, all workers are homogenous.

Economy B: Both workers and employers have perfect information as in Economy A, but there is heterogeneity in workers' productivity.

Economy C: Workers and employers have imperfect information (i.e., workers do not know all of the jobs that are available in the economy. Employers do not know all of the available workers in the economy and cannot perfectly observe how productive workers are). All workers are homogenous, but due to imperfect information, employers individually form a belief regarding workers' productivity and make job offers accordingly.

In all three types of economies, there are many workers and many firms.

Evaluate whether each of the following statements is true or false:

a)In Economy A, there will be only one prevailing market wage rate.

b)In Economy B, there will be only one prevailing market wage rate.

c)In Economy C, it is possible to observe dispersion in wages.

Why? For each statement, explain your reasoning for why you think it is true or false
