Short answer. Country Y (a hypothetical country) funds its public pension system with a 20% payroll tax on formal-sector wages. Workers in the informal sector do not pay the tax. Every retiree receives the same pension, regardless of how much he or she contributed. Assume labor demand and labor supply are neither perfectly elastic nor perfectly inelastic. Using the idea of tax-benefit linkage, explain how the payroll tax affects formal-sector employment and economic efficiency. Answer succinctly in the text box.

Short answer.  In a perfectly competitive market for good Z with no externality, demand and supply are given by Qd = 60 − 3P and Qs = P − 4, where P is the price in dollars and Q is the quantity. The government imposes a $4 per-unit tax that is legally collected from buyers: buyers pay sellers the market price and then pay $4 per unit to the government. Find the price sellers receive, the total price buyers pay (including the tax), and the new equilibrium quantity. Show your work in the text box.

Aazon S3 Provides a good solution for which of  the following use cases?

Short answer.  Countries A and B (both hypothetical) have the same GDP per capita. In Country A, 70% of workers are self-employed or work in small, informal firms. In Country B, 70% of workers are wage employees of large, registered firms. Which country would you expect to collect more income tax as a share of GDP Country A. Country B. They would collect about the same, because their GDP per capita is the same. Not enough information.
