If the inflation rate is 3 percent and the nominal interest rate is 8 percent, how much is the after-tax real interest rate if the government imposes a 20 percent interest income tax? O a. 3.4 percent O b. 4 percent O c. None of the above O d. 5.4 percent.
Assume that the labor demand equation for a fictional country is L d =30-w where w is the wage per hour worked and L d is the number of workers demanded by firms. Assume also that the labor supply equation for that country is L s =0.5(w) , where L s is the number of people willing to work . [LO 9.2,9.5] a. Find the equilibrium wage and quantity of labor employed b . At the equilibrium wage , how many people are unemployed ? c. How would the number of unemployed change if the supply of workers increased ?
Assume that the productivity of farm labour depends on daily caloric intake, similarly to that depicted in Figure17.4. Using this kind of diagram, compare the efficiency wages that would apply to the following two types of workers:
• A landless labourer
• A labourer with small plot of land on which he
grows staple crops
Describe the likely equilibrium unemployment rates and wage rates for landless labourers and small landholders. Judging partially on the basis of this example, what sorts of data and what empirical strategies might you use to see whether nutritional efficiency wages were an important element in the rural labour markets of poor, rural economies?

- The United States has established a progressive income tax system, where a worker’s tax rate onearnings increases as she earns more money. There are 168 hours in a given week. Assume thatfor the first 56 hours worked, the tax rate is t1, which means that the net real wage is w*(1-t1).After working the 56th hour, the worker jumps to a higher tax rate t2. After the 112th hourworked, the individual jumps to an even higher tax rate, t3.(a) During most election years, some politicians argue that a having a flat tax system isbetter. Assume that there is a proposal to institute a flat tax, where all workers pay a taxrate equal to t4, which is greater than t3. On the same set of axes, graph the budgetconstraints associated with the progressive tax system and the flat tax system. Make sureto label all of the slopes.(b) Would moving to this proposed flat tax system likely encourage more or fewer hoursworked for relatively high-wage workers?

Why will not more than that number of workers move to Neon? d. After the move of workers, what will the equilibrium wage rate be in each country? What will the domestic output be after the migration? What is the amount of the combined gain in domestic output produced by the migration? Which country will gain output; which will lose output? How will the income of native-born workers…arrow_forward
