Learning outcome of this chapter 2: Identify the critical assumptions of the two-sector model, define what is meant by a Pareto-optimal allocation of resources; articulate the three conditions for a general equilibrium; distinguish between allocative efficiency, X-efficiency, and ‘dynamic’ efficiency (or economic growth); discuss the broad categories of market failure; explain the allocative, distributive, and stabilisation functions of government; distinguish between direct and indirect forms of government intervention.
