(four factors ) The Harrod-Domar ModelComparative Statics: If the financial savings rateincreases from s to s does the expansion charge go up, down, or keep the identical? Present how youarrived at your reply.three.(15 factors ) The Solow ModelComparative Statics: Present graphically how thesteady-state stage of capital modifications in response to modifications within the following parameters.(a) s will increase(b) d falls(c) n falls4.(10 factors ) Rising Returns and Imperfect Competitors: Suppose a brand new pieceof pc softwaresay a phrase processor with good speech recognitioncan be created fora onetime value of $100 million. Suppose that after its created copies of the software program can bedistributed at accost of $1 every.(a) If Y denotes the variety of copies of the pc program produced and X denotes theamount spent on manufacturing, what’s the manufacturing functionthat is, the relation betweenY and X ?(b) Make a graph of this manufacturing operate. Does it exhibit growing returns? Why or whynot?(c) Suppose the rm fees a worth equal to marginal value ($1) and sells one million copies of thesoftware. What are its prots?(d) Suppose the rm fees a worth of $20. What number of copies does it should promote so as tobreak even? What if the value is $100 per copy?(e) Why does the dimensions of the marketthe variety of copies the rm might promote matter?5.(10 factors ) A rise in analysis productiveness: Suppose the financial system is growingat a relentless charge within the Romer mannequin, after which within the yr 2030, analysis productiveness, z risesimmediately and completely to the brand new stage z .(a) Clear up for the brand new development charge of data and yt .(b) Make a graph of yt over time.(c) Give two explanation why analysis productiveness could enhance in an precise society.6.(5 factors ) A rise within the preliminary inventory of data: Suppose we have now twoeconomieslets name them Earth and Marsthat are equivalent, besides that one begins with astock of concepts that’s twice as massive as the opposite: AEART H = 2AM ARS . The 2 economies are00to this point aside that they dont share concepts, and every evolves as a separate Romer financial system. On asingle graph, plot the habits of per capita GDP on Earth and Mars over time. What’s theeect of beginning out with extra information?
