please answer this econometrics question in pen paper mode 1. Consider a simple panel structure consisting of 16 main Indian states over the time period 2000 to 2005.Export performance of the states depends on the real gross state domestic product, trade facilitating infrastructure index, relative supply price of export, foreign direct investment and last year export performance. Apart from these factors, state specific time invariant characteristics are also important in determining state level export performance In this situation, current real state domestic product of a particular state is correlated with the random disturbance term of the last year. (a) Construct the suitable econometric model for estimating the above problem (b)Derive the matrix of valid instruments considering all 16 states. 3+7=10

4. In class we studied the (canonical) transformation to Action-Angle variables resulting from generating functions of the form $F_2(q, P)$, i.e. a function of the old coordinates and the new momenta. However, this is not the only possibility. Consider the generating function \begin{equation*} F_1(q, Q) = \frac{1}{2} \omega q^2 \cot 2\pi Q \end{equation*} which transforms the harmonic oscillator problem so that Hamiltonian be- comes \begin{equation*} H = \frac{1}{2} (p^2 + \omega^2 q^2) \to \tilde{H}(Q, P) = \nu P, \qquad \nu = \omega/(2\pi). \end{equation*} In this Hamiltonian we have put the mass $m = 1$ for simplicity. We see that we have in fact arrived at a Hamiltonian written in terms of Action-Angle variables, with Q linear in time. Write out the transformation carefully and verify that indeed the new mo- mentum is $P = \int p dq = J$ (an action) and that Q is the corresponding angle variable.

Electronic chips generate heat and thus they need to be cooled to prevent failure. Microchannel heatsinks that use liquid coolants are an option for cooling electronic chips; the figure below shows a typical microchannel heatsink. It is desired to design a microchannel heatsink for cooling an electronic chip with planar dimensions of 2.54 cm by 2.54 cm and generating 75 W (Q) of heat; the maximum temperature of the electronic chip cannot be greater than 50°C (Tc,max). During operation, the microchannel heatsink will be directly attached to the top of the electronic chip and for this matter its planar dimensions (LHs and WHs) always match that of the electronic chip; the coolant is continuously transported through the entire microchannel heatsink during operation. The heatsink is to be made using silicon wafers which have a thickness of 500 μm (t). The heatsink has multiple parallel microchannels, with the same dimensions, and uses water as the coolant. The inlet temperature of the coolant is 10°C (Tin). Due to manufacturing limitations, the microchannel width (WcH) and microchannel spacing (Wsp) of each microchannel cannot be smaller than 50 μm and the depth cannot be greater than 300 μm (HcH). As microchannels are employed in the heatsink, the maximum width and spacing of the microchannel is always kept below 1000 μm. The maximum volumetric flow rate (V) possible through the entire microchannel heatsink is limited by the allowable pressure drop between the inlet and outlet, which cannot be greater than 5 Psi (Pmax). Once the microchannel heatsink is designed and fabricated, it is sealed using a glass wafer; thus, the glass wafer is not part of the design process of the microchannel heatsink. Listed below are several parameters associated with the design process of the microchannel heatsink. Categorize the below-listed parameters as requirements, given quantities, design variables, and constraints. (Points 5) a. Heat generated by the electronic chip b. Length of the heatsink c. Width of the heatsink d. Inlet temperature of the coolant e. Material of coolant f. Material of the heatsink g. Width of the microchannel h. Depth of the microchannel i. Thickness of the silicon wafer j. Spacing between microchannels k. Volumetric flow rate of the coolant l. Maximum temperature of the electronic chip m. Maximum allowable pressure drop in the microchannel heatsink n. Energy equation
