why eventhough the r is denominator in LM formula, the slope of LM still goes upward

Alright! Let me simplify this for you. We’re talking about the **LM curve**, which shows the relationship between **interest rates (r)** and **income (Y)**. Now, you’re asking why this curve **slopes upward**, even though **r** is in the denominator in the formula.
### Imagine this situation:
1. **You have money in your wallet**, which you use for two main reasons:
- To **buy things** (this depends on your income, how much you make).
- To **save or invest** in something like a bank account that earns interest (this depends on the interest rate).
2. **When your income (Y) goes up**, you need more money because you're buying more things. But there's only a certain amount of money in the economy (we'll call this the **money supply**).
3. Now, **interest rates (r)** affect how much money people want to hold in cash (in their wallets) versus how much they want to save or invest. **If interest rates go up, people want to save more money in the bank and hold less in cash**.
---
### The Core Question:
If **r** (interest rate) is in the denominator, that means as **r** goes up, money demand (L) should go **down**. So why does the LM curve still **go upward** (showing a positive relationship between r and income)?
### Simple Explanation:
Think of it like this:
- When **income (Y)** goes up, people need **more money** for their daily transactions. But the money supply is fixed (there’s only so much money to go around).
- To make sure everything stays balanced (because you can't magically print more money), **something else has to change** to reduce people's demand for money.
- The **interest rate (r)** is what changes! **As people’s income goes up**, and they need more money, the **interest rate has to go up too**. This **higher interest rate** encourages people to save more and hold less cash, **keeping the money market balanced**.
### Why Does the LM Curve Slope Upward?
When people’s **income increases**, they want more money. But since the money supply is fixed, **interest rates must rise** to reduce the amount of money people want to hold. That’s why, on the graph, as **income (Y)** goes up, **interest rates (r)** also go up. This gives the LM curve its upward slope.
---
### Visualize It:
Imagine a seesaw:
- On one side is **income (Y)**: as it goes up, people need more money for buying things.
- On the other side is **interest rate (r)**: as it goes up, people hold less money and save more.
For the seesaw to stay balanced (meaning the money market stays in equilibrium), **both Y and r need to go up together**, which creates the upward slope of the LM curve.
### Final Thought:
Even though **r** is in the denominator (which makes money demand decrease when **r** increases), the **overall relationship** between **income and interest rate** still leads to an upward-sloping LM curve because **higher income leads to higher interest rates** to keep the money market balanced.

Why the government of Japan increase their interest rate?
Recent newsThe Japanese government, through the Bank of Japan (BOJ), raised interest rates in August 2024 in response to growing inflationary pressures. Japan had experienced years of low inflation, even deflation, but by mid-2024, inflation had accelerated beyond expectations, driven by higher energy costs, a weakening yen, and global supply chain disruptions. These inflationary trends threatened the BOJ's long-term price stability target.

The formula of buble
Recent newsAn **asset bubble** doesn't have a single, universally accepted formula, but it can be understood through a combination of economic models and indicators that show when asset prices deviate significantly from their intrinsic or fundamental values. Typically, asset bubbles occur when the prices of financial assets, such as stocks, real estate, or commodities, rise rapidly and unsustainably due to speculative demand, often detached from the underlying economic fundamentals.
