Sadly I have so little knowledge of economics that I can barely read the news these days. Answering my questions the old fashioned way (via Google) tends to confuse me more. So I asked chatGPT, but I know its answers aren't always accurate. Please tell me if its answer is flawed in any way. And if you can give a better answer, please do so.

Please explain to me how all of the following things relate to each other, either causally or by correlation: national public debt; inflation; economic strength; currency value; unemployment level; interest rates; taxes; stock market; bond yields; wages. Please avoid vague language like "can be influenced by," which doesn't explain the direction of influence. There is no need for you to define the terms for me, only their relationships to each other.

Here are the relationships between the economic concepts you listed:

National public debt and inflation are positively correlated, meaning that an increase in the national debt may lead to inflation. The reason is that if a government borrows a lot of money, it may have to print more currency to pay off the debt, which can increase the money supply and lead to inflation.

Economic strength and currency value are positively correlated, meaning that a strong economy can strengthen a currency's value. A country with a strong economy is likely to attract foreign investment, which can increase demand for its currency, leading to appreciation.

Unemployment level and economic strength are inversely correlated, meaning that a strong economy can lead to lower unemployment rates. Conversely, a weak economy can result in higher unemployment rates.

Interest rates and inflation are positively correlated, meaning that higher interest rates can help to control inflation. Central banks typically raise interest rates to curb inflation by making borrowing more expensive, which can reduce demand and bring prices down.

Taxes and the stock market are inversely correlated, meaning that tax increases can negatively impact the stock market. Higher taxes can reduce disposable income, reducing consumer spending and corporate profits, which can lower stock prices.

Bond yields and interest rates are positively correlated, meaning that an increase in interest rates can lead to higher bond yields. Higher interest rates increase the cost of borrowing, which can increase the yield on bonds to compensate investors for the added risk.

Wages and inflation are positively correlated, meaning that wages tend to rise with inflation. As prices increase, consumers demand higher wages to maintain their purchasing power.

It is essential to note that these relationships are not absolute and can be influenced by various factors, such as government policies, market forces, and global events.

National public debt and inflation are positively correlated, meaning that an increase in the national debt may lead to inflation. The reason is that if a government borrows a lot of money, it may have to print more currency to pay off the debt, which can increase the money supply and lead to inflation.

Well this is more or less correct. Indeed one way how to solve government debt issue is through what is called monetization of debt. It is not necessarily by printing money, most money nowadays are created electronically, but its ok analogy as explanations goes. Indeed monetizing debt can lead to inflation there is positive relationship between money supply and inflation, and historically when governments tried to monetize debt it often resulted in quite a large inflation (there is good chapter on that it Rogoff & Reinhart This time is different, although note the research there about debt and growth was discredited, but the chapter on inflation is good).

However, that there isn't necessarily causal link between government debt and inflation per se. That is large government debt that will simply be paid from future taxes should not lead to sustained inflation on its own. To be fair to chatGDP it does not claim there is, it only talks about correlation, but if you are not aware of basic statistics you might not realize that correlation is not sufficient condition for causality to be present (although causal relationship will have correlation, even without causality correlation can be present).

Economic strength and currency value are positively correlated, meaning that a strong economy can strengthen a currency's value. A country with a strong economy is likely to attract foreign investment, which can increase demand for its currency, leading to appreciation.

It is correct that economic strength and currency are correlated, but here chatGDP should actually say they are causally related. Virtually or modern theories on exchange rate claim these are causally connected (e.g. see textbooks such as Copeland Exchange Rates and International Finance or Mark International Macroeconomics and Finance, and saying that would be uncontroversial so here chatGDP should respond that stronger economy causes currency value to appreciate instead of saying it is positively correlated.

Unemployment level and economic strength are inversely correlated, meaning that a strong economy can lead to lower unemployment rates. Conversely, a weak economy can result in higher unemployment rates.

Again chatGTP talks about correlation, but pretty much no economist on earth would claim that this is just correlation. To produce more output, ceteris paribus, we have to employ more resources and people. This is clearly causal inverse relationship, not just correlation.

Interest rates and inflation are positively correlated, meaning that higher interest rates can help to control inflation. Central banks typically raise interest rates to curb inflation by making borrowing more expensive, which can reduce demand and bring prices down.

Here the first part of first sentence sentence is clearly wrong. They are negatively correlated. The next part is correct higher interest rates lower inflation (so they must be negatively correlated).

There are some legitimate economic theories that claim there should be positive relationship between interest rate and inflation (i.e. Fisher effect). My best guess would be text that deal with fisher effect is where the chatbot got first half of the first sentence. But empirically speaking this is rare and chatGDP is correct in the second half where it says that higher interest rates help to reduce inflation.

Taxes and the stock market are inversely correlated, meaning that tax increases can negatively impact the stock market. Higher taxes can reduce disposable income, reducing consumer spending and corporate profits, which can lower stock prices.

This is not generally true statement. To unpack this statement completely one would need separate SE question and answer, but in short, trivially not all firms are listed in stock market. If there is some tax that has incidence that falls solely on non-listed small businesses, or even worse one that makes people to substitute shopping at small business by shopping at big listed one (e.g. VAT that only applies on mom and pap shop but not amazon), such tax could even increase stock market returns. So this is simply wrong generally on number of several levels. Of course, there are lot's of taxes that negatively affect firm performance, but one cannot say it about any tax.

Bond yields and interest rates are positively correlated, meaning that an increase in interest rates can lead to higher bond yields. Higher interest rates increase the cost of borrowing, which can increase the yield on bonds to compensate investors for the added risk.

This is true, but again there isn't just correlation. Business can get lending through issuing bonds or directly borrow from banks so via competition, all else equal there interest rates have to be equivalent otherwise nobody would either issue bonds or go to the bank. Here there is reverse causality as well because they both endogenously determine each other, which is another thing that chatGDP does not mention.

Wages and inflation are positively correlated, meaning that wages tend to rise with inflation. As prices increase, consumers demand higher wages to maintain their purchasing power.

This more or less holds for nominal wages. Also, there is mistake, it is labor that demands higher wages (of course all workers are consumers but not all consumers are worker), and in addition it is not necessary guaranteed that wages rise enough so that purchasing power is maintained.

It is essential to note that these relationships are not absolute and can be influenced by various factors, such as government policies, market forces, and global events.

This is correct, of course any relationship, even in physics, works under ceteris paribus condition (e.g. of course even gravity can be counteracted by work etc). So one could see for example stronger economy at the same time exchange rate is falling because even though strong economy increases value of currency there might be other reasons (such as huge monetary expansion, or relative large increase in value of other currency etc).

    $\begingroup$ I asked chatGPT if your comments are correct and it came back with "Overall, the assessments of the chatGPT explanation are mostly correct, but there are some errors and simplifications. The explanations provide a good starting point for understanding these economic relationships, but it is important to remember that these relationships may not always hold true and can be influenced by other factors. It is always a good idea to consult multiple sources and to consider the nuances of each relationship." Good job! $\endgroup$
