I have two parts. Please explain all parts in detail.

(1). Poor countries have lower capital stock levels compared to wealth countries. Therefore in order for a developement policy to be effective it must target the saving rate.

(2). The prediction of solow growth model are inconsistent with the empirical evidence regarding income convergence.

Let the US economy be characterized by low aggregate output and low and stable inflation. Then, provide a clear definition of the Phillips Curve and consider whether this initial state is consistent with what is shown by this empirical relationship. Conclude by discussing under what conditions expansionary fiscal and monetary could lead to demand-pull inflation. How is economic growth impacted?

Azulene is a beautiful blue hydrocarbon consisting of only C and H atoms. If 0.106 g of the compound is burned in oxygen, 0.364 g of CO2 and 0.0596 g of H2O are made. Determine the empirical formula of azulene from this data. [ Hint: First convert the masses of CO2 and H2O to moles, then convert the moles found to moles of C to H. ]

Grounded theory is a research method that seeks to develop theory that is grounded in data systematically gathered and analyzed. According to Martin and Turner (1986), grounded theory is "an inductive, theory discovery methodology that allows the researcher to develop a theoretical account of the general features of a topic while simultaneously grounding the account in empirical observations or data." Discuss the techniques of grounded theory.
