A group of college students start a dog-walking service. At the end of the first month, they meet to discuss their business performance. Which statement reveals sound economic thinking in their analysis

(4 points) suppose the production function in the solow model is given by yt = ak¯ 3/4 t l 1/4 t . (a) what are the five equations and five unknowns that summarize the solow model? (b) show the transition dynamics in the solow model if ¯sy0 < ¯dk0. make sure you label the axes, curves, initial level of capital and steady-state level of capital. (c) solve for capital, output, capital per person, and output per person in the steady state. (d) if a¯ = 2, l¯ = 4, ¯s = 0.2, and ¯d = 0.05, calculate the steady-state level of capital and output per person.

The sticky-price theory asserts that the output prices of some goods and services adjust slowly to changes in the price level. suppose firms announce the prices for their products in advance, based on an expected price level of 100 for the coming year. many of the firms sell their goods through catalogs and face high costs of reprinting if they change prices. the actual price level turns out to be 110. faced with high menu costs, the firms that rely on catalog sales choose not to adjust their prices. sales from catalogs will

One pound of material is required for each finished unit. the inventory of materials at the end of each month should equal 20% of the following month's production needs. purchases of raw materials for february would be budgeted to be:
