Question:
Hi! I'm trying to do more reading on economics this summer as I consider applying to master's of economics programs after working in IT for 13 years. I came across a paper (linked at the bottom) on inequality. I only have an undergraduate level understanding of economics and statistics (think intermediate micro/macro and an introductory stats class I took around 2003) so I'm limited in my understanding.

I'm reading through this paper and while I can think of reasons why some of the conclusions might be true I don't get how empirically they are reaching their conclusions.

1) According to page 16 item #23 "The empirical results show that inequality has a negative impact on economic growth. The baseline results are reported in columns 1 to 4 of Table 1" and then goes on to explain its reasoning why inequality negative impacts growth and says "Based on the estimated coefficients in column 1, for example, lowering inequality by 1 Gini point would translate in an increase in cumulative growth of 0.8 percentage points in the following 5 years".
2) In item #29 (page 19) they go on to say "Taken together, these results suggest that inequality in disposable incomes is bad for growth, and that redistribution is, at worst, neutral to growth". Again while I can think of some reasons why this may be the case (and some reasons why it may not like if some of the wealth leaves the country so as not to get redistributed depending upon implementation) I'm not sure how they are coming to that conclusion empirically.
3) Then several times they estimate what the impact on growth would be for every % change in the Gini index but I'm not sure how they built that numerical assumption.

I came across the paper because I was trying to do some simple research into whether income inequality can lower the velocity of money (though so far I've just pulled some data from FRED on MZM and the Gini index and found like a -.46 correlation.

I'm hoping I could learn from someone to better understand how the tables this paper provides actually translates into the conclusions they claim; I don't know how to properly interpret the tables.

Question:
I know that when there is too much of something the value of that item goes down. If the money supply of US Dollars goes up drastically that will that lead to or cause inflation of the US dollar or a decrease in its value. According to an article I am referencing *," When inflation starts to bubble up, Treasury inflation-protected securities can turn down the heat on your portfolio. Issued with the full faith and credit of the U.S. government, TIPS are one of the few investments guaranteed to earn, under normal circumstances, a "real," or after-inflation, return. Their principal value adjusts in sync with the consumer price index and, because the coupon payments on TIPS cue off this adjusted principal figure, the bonds pay an inflation-indexed income, too."
So my question is: if the US dollar loses 10 % of its value to inflation, how much will the bonds return? In dollar amounts- a $5000 investment in Treasury inflation-protected securities should yield how much?
* http://m.kiplinger.com/article/investing/T041-C000-S002-why-you-need-tips.html
Answer:

Suppose that $5000 is the face value or redemption value (not the market price at which an investor may have bought it) of a 5-year TIPs. Suppose that it promises to pay an annual coupon payment of 1% or the amount of $50 at the time of purchase...

Question:
I watched President Obama’s speech this last week, and I didn’t understand something. He said he’s cut the deficit by 2/3. Yet, we need the debt ceiling raised in order to avoid a government shutdown. Why? If I were to pay down 2/3’s of my debt, I would have a larger amount of credit available to me. What am I missing?
Answer:

You are missing a key difference between the federal budget deficit and the public debt level. The deficit shows by how much the federal government expenditures exceeded its revenues in a given fiscal year; the deficit is measured per year. In...

Question:
One of the macro economic indicator that is monitored by organizations is "the contribution of construction to the GDP". This is measured in terms of percentage contribution of construction.

My question is:
What does this comprise? Does it include large infrastructure projects/oil refineries/nuclear plats etc or not?
Answer:

As you probably have seen already, you can find the measure of value added to GDP per sector of the US economy at the Bureau of Economic Analysis website, specifically at this web address: https...

Question:
With all the killing of poultry by bird flu and euthanizing that will this do to the retail poultry prices?
Answer:

Avian influenza has continued to spread, particularly in flocks of egg-laying hens. When a farm encounters a case of avian influenza, some birds die and others are euthanized. In the immediate short-run, this translates into a direct reduction in...

Question:
Can an economist call the economy good when there is low unemployment, good profits, but great income disparity? Is it within the realm of the social science of economics to consider social justice?
Answer:

Economists measure the economic health of a country by its G.D.P per capita. They see low unemployment as good because it means labor resources are not sitting idle. They also consider whether income disparities are good or bad. In fact, these...

Question:
Hi!

I wanted to value a high-tech start-up of which I have the cash flows of the coming 6 years. I am not a VC just a post-grad student, so I decided to use the discounted cash flow method. To do so, I calculated the discount rate. For a high-tech start- up the discount rate = Rate of equity (which can be determined by the capital asset pricing model). So I calculated my discount rate, used it in the DCF model, and found an approximation of the value of the high-tech firm.

But I didn't take into consideration that the company sells their products globally. This fact has an impact on its beta factor, and consequently on the discount rate, and finally on the value of the firm!

One option is to use the International CAPM model, but my company is going to sell globally, so how do I know the impact of that to the discount rate? Any help would be very appreciated.

Thanks
Answer:

If your company is based in the U.S., the valuation should be based on the standard CAPM. However, barring exceptional circumstances, one would expect the beta of such a firm to be closer to zero than the beta of an otherwise identical firm...

Question:
I wonder what "reduced-form analysis" is, and a non-reduced form would be. To be more specific, I'm reading an article (www.clevelandfed.org/research/review/1996/96-q1-craig.pdf) which states the following:

"Economic data usually influence policy through a reduced-form analysis...Explicit assumptions about behavior that underlie the relationship are not emphasized; rather, the researcher asserts that the “data do the talking.”"

The author later specifies what he means by "reduced-form":

"We use the term in a wider context, where the pattern in the data — not an assumed behavioral structure — forms the point of departure for estimation."
Answer:

A “reduced-form” analysis, also often referred to as “non-structural” analysis, is the most common kind of econometric analysis performed by economists. The other kind, which you called “a non-reduced form,” is customarily referred to as “...

Question:
Hello!

1) What do economists think of the Lange model: https://blogs.cornell.edu/info2040/2015/10/19/the-lange-model-of-socialism/? Does it adequately address the economic calculation problem? Tying into this question, is is true that Robin Cox is thought to have won the debate around the ECP? Or was it Mises, Hayek, or James Scott?

2) Finally, I would appreciate any insight toward this economic system: Instead of prices, it uses calculation in kind. It accomplishes this by decentralizing economic decision-making, by means of turning firms into self-managed associations joined in horizontal federations, which assess how much is taken at distribution centers by means of book-keeping and assess how many physical quantities of the goods they particularly use are required. I know this is a bit brief, but the part of this comment that explains this further starts with "But now, there is still a question to answer, how could an economy not based in prices make rational decisions" (it's toward the end).": https://www.reddit.com/r/CapitalismVSocialism/comments/4ib76d/automation_capitalism_v_socialism/d2wx6la/?utm_source=share&utm_medium=web2xthat.

Any insight would be greatly appreciated!

Question:
My country is currently debating the prospect of banning live exports of sheep to the Middle East, due to the abhorrent conditions that the animals suffer on the journey over there. Our Agriculture Minister has come out and said "We should tighten regulations instead, because if we ban live exports entirely, then these countries will instead import from other countries with lesser regulations, and there will be no overall reduction in animal suffering."

Does his claim hold up? If other countries have enacted similar bans, what happened afterwards?

Context: https://www.theguardian.com/australia-news/2018/jun/09/live-export-opponents-should-check-their-moral-compass-minister-says

Cheers!
Answer:

I am not aware of any restrictions on live animal exports centered on animal welfare concerns. Concerns about animal disease outbreaks and food safety have primarily led to trade restrictions on live animals, meat, and animal products. A little...

Question:
How high can our national debt get (as a % of GDP) before it will be a threat to our financial stability? ie: dollar loses its status as the reserve currency.
Answer:

The national debt of the US is the amount owed by the US federal government and is the value of the Treasury securities that have been issued primarily by the Treasury and which are outstanding at that point of time. By far, the largest component...

Question:
I am familiar with Karl Fox et al. "functional economic areas" framework of regional modelling. I am also aware of REMI products. These latter models are widely used by state and local governments. But I am not aware of the availability of computer models that would use functional economic areas per se. Can you inform me if there are such models that might be an alternative to REMI? Thank you.
Answer:

Any subnational economic modeling includes two challenging components: data and structure.  Detailed subnational data for the US is automatically suspect because input-output tables are not collected at any subnational level. ...

Question:
If a business owner employs workers in a third world country, is it better (for the workers) to pay them in strong American dollars vs paying them with the local currency? Considering the American dollar will likely be stronger than that of a third world country, the workers will have more economic power with greenbacks than their own national currency.
Answer:

If the third world country has low and stable inflation, then it should not matter much; after all, there is a market exchange rate between say $1 and Indian rupees (these days, $1 = Rs. 60) and whether you pay an Indian worker $1 or Rs 60 should...

Question:
Why did China’s banking system grow so much since 2000 if the PBOC was actively increasing the RRR and withdrawing liquidity through FX Reserve purchases?
Answer:

First of all, I want to make it clear that, when a central bank increases its FX reserves, it supplies local currencies and increases liquidity in the money market. But this is certainly not the reason that China’s banking system grew so much....

There is a large literature that attempts to adjust the various conventional measures of economic growth for the effects of environmental degradation. There is a useful Wikipedia page on the topic (...

Question:
Hi there, thanks for taking the time to answer my question.

I understand the basics of measuring GDP based on the product, income, and expenditure approaches, but I am stuck on a simple question: how are household savings accounted for using the expenditure approach if they are not invested?

In other words, say I earn $100, spend $98, and deposit $2 in a non-interest earning savings account. If the $2 (along with a lot more money, presumably) gets lent out to a company that builds a factory, then clearly that would be investment, but what if it just sits in the savings account? Does that count as “residential investment”?
Answer:

There are two components to investment in the national income identity. In addition to expenditure on capital equipment and buildings by firms, investment also includes additions to business inventories (goods that firms did not sell). So if you...

Question:
When Minimum Wage is increased by more than 5%, studies have shown a negative impact for one to three years - job loss, reduction of hours, and non-hiring to replace workers leaving - causing a reduction of pay of low pay workers, a 1-3% reduction in teenager hired, and failure of many start-up businesses. I have not found longitudinal studies showing where the economy rebounds from these losses and whether there is a long-term benefit at all for the lower or higher wage workers. Has there been studies going longer showing when the (a) teenage hiring returns to previous levels, (b) hours return to normal for the low pay workers, etc... Is Minimum Wage a permanent negative impact or temporary? ... I've seen what happens statistically for things like holidays - where a sick person will power through the holidays, but then die immediately thereafter, creating an average between "less deaths during the holiday" and "more death just following" matching normal death rates. And studies which show that capital punishment creates a permanent troth with an immediate reduction of several months after a criminal has been executed without a rebound increase afterwards ... just a return to normal levels. .... So which is it, a permanent loss to the economy when we have minimum wage raised that never recovers; a temporary loss to the economy which returns to the previous level but no further; a temporary loss to the economy but a rebound that balances and then return to average; OR a temporary loss to the economy but a long-term gain once everything is considered? Everything I have found indicates a permanent loss to the economy with no upside and that just doesn't make sense to me as yet. If there are longer studies, I would appreciate finding out about them. Asking because I would like to support a higher minimum wage, especially for tip-income wages, but based on the evidence I have found I cannot.
Answer:

The adverse effects of the minimum wage depend on how high it is compared to the prevailing wage in the area.  Because wages are higher in San Francisco than Des Moines, a $15 minimum wage in San Francisco, where the median wage is $25.11,...

Question:
If 25% of the US population left their 401k (and other retirement funds) alone, reduced contributions by 25%(50%, 75%, 100%), withdrew all non-penalized funds and kept personal savings out of their banks, did not otherwise invest their money, what would happen nationally, internationally, immediately, long-term?
Answer:

My best guess is that you are interested in the effects of investors withdrawing from the financial market (as opposed to the labor market or some other market).

If 25% of the US population suddenly changed their investment behavior as you...

Question:
Why is it that the largest market fluctuations, by a large majority, mainly happen in September, October and November? What about those three months causes the massive fluctuations? It happened in 1929, 1987 and 2008.

At present, I am not aware of a widely accepted academic research in economics and finance that would provide a definitive explanation for the exact calendar timing of major financial market fluctuations in the United States for the time period...

Question:
I here a bit more these days about our being a consumer economy. What other types of economies are there?

Thanks a bunch!
Answer:

Ours is called a consumer economy because consumption is nearly 70% of our GDP. Countries like China, are more investment-driven with investment (often by the public sector) at nearly 50% of GDP.

Question:
Hello, I'm a 42 year old woman from Los Angeles CA. Due to personal reasons I left the state for about 10 years. Now that I'm back, I noticed that things have changed a lot! For example: when I was a young adult, I used to work as a waitress. I remember that most of my co-workers were about the same age and most of us were attending Junior College. However, now I'm 42 years old, I noticed a completely new group of people. Most are mature, in their mid 30s to mid 40s. A lot of them made careers out of working as servers. How does it affect the economy to have more people pursue careers in minimum wage jobs?
Answer:

First, the characterization of foodservice and restaurant workers as a career track is inaccurate. The median age of restaurant workers is 28.4 years, the second youngest sector of our economy (next to retail shoe stores at 24 years). As shown in...

Question:
Hello, in the article https://news.cgtn.com/news/2020-08-07/China-confident-of-meeting-2020-fiscal-targets-Finance-Minister-SKUFJsrke4/index.html , it says China has been implementing tax and fee cuts, and "issued 100 billion yuan (about 14.1 billion U.S. dollars) of special government bonds for COVID-19 control measures in a bid to support local infrastructure construction and epidemic prevention and control." In what ways will implementing tax and fee cuts help China's recovery? And if selling government bonds is a contractionary monetary policy, what will this do, other than fund fiscal objectives, to help a recovering economy? Why sell bonds instead of borrow more?
Answer:

China mainly cuts corporate tax and fees (no tax cut for individuals) during the COVID-19 epidemic period so that firms could have incentive to increase the production compared to the scenario without tax and fee cuts.
