  • ミクロ経済学について

    大学で経済学を勉強しており、何度かここでお世話になっております。 ミクロ経済学の問題で、どうしても意味のつかめないところがあります。 手助けをおねがいします! An expert tells you: If demand goes up, the price will go up. Hence the Demand curve is positively sloped. Is this correct? 答えは以下のとおりです。 No, that's wrong. The demand curve maps the price of a commodity on the demand for that commodity (p 7→D(p)). If demand goes up for some reason (e.g. higher income, stronger preferences, higher prices of substitutes) then the curve shifts to the right: for any given price of the commodity, demand is higher. Given an upward sloped supply curve, the market equilibrium price will rise. 問題自体は難しくはないのですが、positively slopedとは”+に傾斜”という解釈で良いのでしょうか? このpositively slopedの意味がつかみにくいです。 需要が上がれば、需要曲線は右にシフトするので価格が上がると思うのですが、右シフトのことをpositively slopedとさしているんだろうと思い、正解だと思っていたのですが、回答では間違えとなっているので、混乱しています。 もしもわかりましたら、教えていただけますでしょうか。
