マクロ経済学 (1)〜(6)まで分からないです🥹 均衡GDPの公式を当てはめても、選択肢にない解答になり、その先の問題も解けない状態です。 式の作り方から教えていただければ助かります。 よろしくお願いします。

マクロ経済学ⅡI 課題2 (2022年度前期) 問1 以下の式で表される開放経済を考える。 ただし、 この経済は小国で、変動相場制を採用しており、 資本 (資金) 移動は完全に自由である。 C = 140 + 0.4(Y-T)、 I = 150-10r、 G = 100、 T = 100、 L = Y-10r, M=400、P=1、 NX=e-50、r=w、 w = 10 ただし、Cは消費、 YはGDP、Iは投資、 r は国内利子率、 Gは政府支出、Tは税、Lは貨幣需要、Mはマネーサプライ、 Pは物価、 NXは純輸出 (貿易収支)、 eは為替レート (e=100ならば、1ドル100円を意味しているものとする)、 Twは世界利子率を表している。 (1) 均衡 GDPを求めよ。 (2) 均衡為替レートを求めよ。 (3) 政府支出をG=100からG=110に増加する。 このときの均衡 GDP を求めよ。 I (4) 政府支出をG = 100からG=110に増加する。 このときの均衡為替レートを求めよ。 (5) マネーサプライをM=400からM=500に増加する (ただし政府支出はG=100のまま)。 このときの均衡GDP を求めよ。 (6) マネーサプライをM400からM=500に増加する (ただし政府支出はG=100のまま)。 このときの均衡為替 レートを求めよ。

【IV】 次の(A), (B)の設問に答えよ。 ((A)11点,(B) 6点) (A) 次の英文を読んで、 下の設問に最も適切な解答をせよ。 選択式の設問は記号 (アイウエ・・・) を1つ選んで答えること。 A World Bank report recently released suggests climate change could, force 216 million people across six regions to migrate within their countries in the next 30 years, with ""hotspots" emerging within the next nine years ( 2 ) urgent steps are taken. The "Groundswell Part 2" report examines how climate change is a powerful driver of migration within a nation because of its impact on people's livelihoods through droughts, rising sea levels, crop failures and other climate-related conditions. The original Groundswell climate report was published in 2018 and detailed projections and analysis for three world regions: sub- Saharan Africa, South Asia and Latin America. "Groundswell 2" conducted similar studies on East Asia and the Pacific, North Africa, and eastern Europe and Central Asia. Both studies established different scenarios to explore potential future outcomes and identify internal climate in- and out- migration hotspots in each region that is, the areas from which people are expected to move, and the areas to which they might go. The study suggests that by 2050, sub-Saharan Africa could see as many as 86 million internal climate migrants; East Asia and the Pacific, 49 million; South Asia, 40 million; North Africa, 19 million; Latin America, 17 million; and eastern Europe and Central Asia, 5 million. To slow the factors driving climate migration and avoid these worst-case outcomes, the report recommends a series of steps world leaders can take, including reducing global emissions ( 4 ) the goals established by the Paris 2015 climate agreement, and taking steps to better understand the drivers of internal climate migration, so appropriate policies to address them can be developed.
