Try to build a simple Excel simulation of our growth model, streamlined. We can embed it in a full production function, but just use the following for simplicity:
Y0 = AK0α – output is a function of capital I0 = S0 = sY0 – investment is equal to savings K1 = K0 (1-δ) + […]
We frequently see claims that a lower tax rate – particularly of corporate or personal income taxes – will work miracles. That is seldom the case.
First, the stated tax rates are not the realized tax rates. While on paper someone with $500,000 in income is paying a 39.9% rate, the rate on […]
Arbitrage. With perfect foresight and no risk premium the return one-year bond should be equal to the interest rate on a six-month bond bought today, reinvested in a six-month bond bought six months from now. (1+i1)(1+i2)=(1+yr) reflects compounding. Now rates are quoted as one-year rates, so if the six-month rate is quoted as […]
under construction (duh!)
“Long” Treasuries yield a scant 2.6% over 30 years. Basic theory suggests this should should equal expected growth rate plus inflation. If a rise in the CPI of 2% per annum is the Fed’s target, then do investors really expect that to never be attained? or attained but with real growth bouncing around at 1% […]
Clements, Benedict, Kamil Dybczak, Victor Gaspar, Sanjeev Gupta, and Mauricio Soto. 2015. “The Fiscal Consequences of Shrinking Populations.” SDN/15/21. International Monetary Fund.
What is “fiscal sustainability”? They provide a very specific approach.
How do they use “solow”?
What is the “demographic dividend”?
We will continue our discussion of intergenerational transfers and overlapping generations issues. To make it concrete, we’ll look at the US Social Security programs.

As a followup to our class conversation on summer jobs on Friday, here’s a link to an item on “What happened to summer jobs?” on the Forbes Modeled Behavior site.
I post expanded notes from my weekly radio show at Autos and Economics on blogspot.com. This week I was asked to comment on Trump’s tax proposals. That’s a moving target, so I shifted my focus to another theme of the Republican candidates: tax cuts will pay for themselves.
Can you add graphs on […]
Will commenting now work on new posts, given changes made by Helen of ITS? I still apparently have to enable comments in old posts by clicking the option, which shows up only in the “quick edit” screen.
These should now appear correctly using the tabs at the top. I initially failed to shift the menu location of this term’s syllabus so it didn’t show, WordPress issues.
I do a weekly radio segment on the economy on WREL, the local radio station. Here are my notes from the Aug 20th show. These are not necessarily the order in which I presented them, and I avoid numbers when I can – radio is not the medium for conveying data – but I like […]
I will add a schedule and syllabus in late August. This iteration will incorporate many changes, but you can look at the Winter 2015 Archive for an inkling of potential topics and content.
As yet more snow falls, we’re reminded … that it’s the start of spring? While this year is colder than any I remember, though not so bad in terms of total snow, it does raise the question of how to interpret economic data. Of course housing […]
There are 20,000 members of the American Economic Association, the profession’s premier professional association. There are many PhD economists in the US who are not members, particularly at smaller universities. Many – likely most – economists in other countries are not members. So … 40,000 PhD economists globally? What that means is that if a […]

Here are 4 graphs that give an overview of inflation from the perspective of both producers and consumers. Data are percent change from the same month of the previous year.

I have posted the schedule and syllabus: no texts, just readings, and more readings.
Alongside your capstone project, this term I emphasize three overlapping themes. One is an overview of “modern” macro theory, begining with the Solow growth model, then overlapping generations models, then (rational) expectations and endogenizing […]
The recent depreciation of China’s exchange rate with the US$, to which it is pegged, garnered headlines. Until now those watching China believed that the RMB could only appreciate, leading to heightened foreign demand for Chinese assets by foreign speculators. Allowing a modest depreciation and increasing the intradaily trading band from 1% […]
