2. Consider the following two periods panel data model:Wageit = Bo + SoD2 + ß₁ Educit + B₂ Expit +B3Female; + ai + uit, t = {1,2},where D2 is a dummy variable which equals to one in period 2 and zero in period 1.(a) Can we estimate the above model by OLS? Explain why.(b) Explain whether the OLS regression controls for individual-specific unobservedheterogeneity (i.e., a fixed effect a;)?(c) Write down the first differenced model. State which coefficients can be esti-mated by OLS?(d) Explain whether the first differenced model controls for individual-specific un-observed heterogeneity (i.e., a fixed effect a;)?(e) Write down the demeaned model. State which coefficients can be estimated byOLS?(f) Show that the models in (c) and (e) are actually equivalent.

Seedlings of understory trees in mature tropical rainforests must survive and grow using intermittent flecks of sunlight. How does the length of exposure to these flecks of sunlight (fleck duration) affect growth? Researchers experimentally irradiated seedlings of the Southeast Asian rainforest tree with flecks of light of varying duration while maintaining the same total irradiance to all the seedlings. Below is the data. Fit a linear model to the data.
