The slides, quizzes, and practice problems for Lecture 14 can be downloaded as PDF files from the above URL.
(This video allows you to display Japanese and Chinese subtitles from the YouTube settings. Enjoy it even when you're out and about, such as during your commute.)
Introduction to Let's Start Economics
You can systematically learn introductory economics content through 16 video lessons.
The lessons were created with a strong focus on clarity and accuracy.
The topics covered in this course are equivalent to those studied by first-year economics students, but they all represent the core of economics.
We hope that you will learn the fundamentals of economics in this course and use them to further your own development.

• Efficient Learning Methods
Here's a brief overview of recommended learning steps.
While you can simply watch the video lectures from Lecture 1, following these steps is more efficient for steadily deepening your understanding.
Step 1: Watch the first lecture.
Step 2: Solve the problems in the first lecture of the problem set "Let's Start Economics."
Step 3: Watch the second lecture.
Step 4: Solve the problems in the second lecture of the problem set "Let's Start Economics."
Step 5: Watch the third lecture (and repeat).
The problem set can be downloaded from the course homepage (URL at the top).
Studying is about "slow and steady wins the race." Understanding deepens only by diligently working through problems.
If you are serious about studying economics, please make use of the problem set.
For more detailed learning instructions, please watch the "Guidance" video in the curriculum above.
Also, a tablet device such as an iPad is convenient for using the problem set, so the following video briefly explains how to use an iPad.

ところで質問させて下さい。
物価とy軸の国民所得(GDP)の関係ですが、ISLM分析だと物価上昇(M/P)するとマネーサプライが減少してLM曲線が左シフトし国民所得が減少してしまいます。確か物価上昇は国民所得上昇の因果関係があったと思うのですが、物価と国民所得の関係をISLM分析で見る事自体が間違ってるという事でしょうか？物価と国民所得の関係はADAS分析でのみ見れば良いという事なのでしょうか？ご回答頂ければ嬉しいです。よろしくお願いします。
質問さえてください。
「Yが増えるとL1が増え、rが上昇する」
これはグラフの動きとしては視覚的に理解できるのですが、「Yが増えるとrが上がる」というのが直感的に理解できません。
例えでYが給料だとすると、給料が増えるとなぜ利率が上昇するのか、よく分かりません。
本業の方でお忙しいとは思いますがお手隙の際にご確認いただけますと幸いです。
という理論が共存できるのかが謎です。おそらく財市場と貨幣市場という風にそもそもの市場が別だから利子率と所得の関係も真逆になっていておかしくないということになると思うんですが、それを考えていると、じゃあ財市場、貨幣市場ってそもそも何なんだという疑問に戻ってきてしまいまして、質問させていただきました。すでに質問されている方に変身されている内容も読んだうえで質問させていただいております。
講義中で、「Yが高くなるとrも高くなる」とありましたが、円安政策で額面だけ給与(GDP)を高く見せた場合に、利子率も上がるので、海外投資家から見て円が魅力的になり、円が買われ円高になるということでしょうか。
それであればマネーストック を無闇に増やしても円の価値が下がらないので安心ですが。それともこの場合のYの上昇は実質価値の上昇のことでしょうか。
