1. Explain the meaning of poverty and economic development in a global context.

2. Compare and critique the predictions of the basic models of development.

3. Assess the pros and cons of various macroeconomic policies from the perspective of developing nations.

4. Apply both quantitative and qualitative development models to discuss the importance of population growth, health, education, and governance.

5. Describe the significance of economic, political, historical, geographical, institutional, and environmental factors involved in the development of poor nations.

Question 1

The signal flow graph for a system is given below. The transfer functionY(s)U(s)Y(s)U(s)for this system is?

Question 2

The impulse response of a continuous time system is given byh(t) =(t-1) +(t- 3) . The value of the step response att= 2 is?

Question 3

Two magnetically uncoupled inductive coils haveQfactorsq1andq2at the chosen operating frequency. Their respective resistances areR1andR2. When connected in series, their effectiveQfactor at the same operating frequency is?

Question 4

The following arrangement consists of an ideal transformer and an attenuator which attenuates by a factor of 0.8. An ac voltageVWX1= 100V is applied across WX to get an open circuit voltageVYZ1across YZ. Next, an ac voltageVYZ2= 100V is applied across YZ to get an open circuit voltage VWX2across WX. Then,VYZ1/VWX1,VWX2/VYZ2are respectively?

Question 5

Thyristor T in the figure below is initially off and is triggered with a single pulse of width 10 s. It is given thatL=(100)HL=(100)HandC=(100)FC=(100)F. Assuming latching and holding currents of the thyristor are both zero and the initial charge onCis zero, T conducts for?

Assume that the government decides to keep the social security tax at initial level , and that parameters are such that the economy is always dynamically efficient. Note that to solve what follows you have to consider the general equilibrium effects that the change in the flow of immigrants has on wages and the interest rate.

b) What is the effect of the shock on capital accumulation in the first period (compared to capital accumulation in the previous steady state)? And on the new steady state? Explain (if you prefer not to do the math you can explain in words what is the intuition).

c) Are the initial old better off? What is the effect on the disposable income of the first young generation of residents. Explain.r
