Suppose that country XYZ has a production function of YY = \beta \beta KK0.3LL0.7. This country’s output increased from 200 to 210 from 2022 to 2023. During the same period, capital stock increased from 1000 to 1050 while its labor force increased from 100 to 103. What are the contributions of capital and labor to the economic growth? What is the Solow’s Residual? Prove the marginal product of capital is diminishing.

Studies derived from Hogg's (2007) uncertainty-identity theory suggest that people are especially likely to identify with groups if they: O are uncertain about themselves, and the group has clear boundaries. O come from an individualist culture, and the group makes them feel valued. O come from a collectivist culture, and the group makes them feel valued. O are uncertain about themselves, and the group has open, flexible boundaries.

Consider the region R in R 2 shown here; it is the parallelogram on the right. In this problem, you will do a change of coordinates to evaluate: Z Z R (x − 2y) dA (a) Find a linear transformation T : R 2 -> R 2 which takes the unit square S to R. (b) Compute Z Z R (x − 2y) dA by relating it to an integral over S and evaluating that.
