Cool new article alert 🚨: Tax Base Fragmentation as a Dimension of Metropolitan Inequality by @robertmanduca.bsky.social, @bhighsmith.bsky.social, Jacob Waggoner.

Love seeing this use of our tax base fragmentation viz!!

🚨We analyzed 138 million geocoded property tax records to quantify how municipal boundaries spatially overlap onto economic segregation in every US metro area—creating disparities in localities’ ability to fund public goods. And we made an interactive map of our results! [1/16]

We conceptualize ‘tax base fragmentation’: the spatial concentration (within a metro area) of property wealth in particular wealthy municipalities. The concept is intuitive—but not captured by existing measures of segregation and jurisdictional fragmentation. Link: academic.oup.com/ser/advance-...

"Cuts to social programs will have a major impact on local economic activity." Social programs are a key part of the regional economic base. @robertmanduca.bsky.social on how Medicaid and SNAP cuts in the #ReconciliationBill will negatively impact local economies:
equitablegrowth.org/medicaid-and...

Starting in 10 minutes!

A lot of the discussion of the reconciliation bill has focused--rightly--on the consequences for beneficiaries of these programs. 11 million people are at risk of losing Medicaid coverage, and 4.5 million stand to lose SNAP. That's a ton. But the economic impacts may be even more widespread

Opinion | My Journey Deep in the Heart of Trump Country

In Kentucky's 5th congressional district, recently profiled by Arlie Hochschild for @nytimes.com, Medicaid makes up a quarter of the entire economic base. The SNAP and Medicaid cuts would be like losing one-third of all traded private sector industries

www.nytimes.com/2025/06/09/o...

If we look just at the proposed *cuts* to Medicaid and SNAP, it's the economic equivalent of Maine losing its entire forestry and paper manufacturing industries, all at once--or Alaska losing 60% of its oil and gas industry.

Put another way, Medicaid contributes roughly as much to Detroit's economy than car manufacturing, more to Houston than the chemical industry, almost twice as much to Los Angeles as motion picture production--these are big numbers!

As I describe in a post for @equitablegrowth.bsky.social, these programs are major foundations for local economies nationwide. Medicaid alone makes up about 11% of the economic base of US regions, and SNAP is about 1.4% equitablegrowth.org/medicaid-and...

Shifting from economic geography to policy, what does this mean for the current reconciliation bill? The House version is set to cut Medicaid and SNAP by about $1.2 trillion over the next 10 years--that's roughly a 12% cut to Medicaid and 27% to SNAP www.cbo.gov/publication/...

In some parts of Florida--looking at you, Cape Coral--traditional traded industries make up just *5 percent* of the economic base. The rest of the economy is based on retirement savings, pensions, Social Security, Medicare, etc.

Financial income made up another 26%. Traded sector earnings were just 24%: less than either of the other sources, and down from 35% in 2001

I compute the share of *all* economic base income that comes from transfers, financial income, and earnings in traded industries (the standard definition). The results are pretty striking: in 2022, transfer payments accounted for *40 percent* of the economic base across US regions

Usually, researchers define the economic base = traded industries only. But selling products to other cities or countries isn't the only way money can enter a local economy. I explore two other sources: financial income and government transfers. Like exports, these payments sustain the local sector

The two sectors play different roles in the local economy: most residents are employed by the local sector, which typically accounts for about 2/3 of jobs. But the traded sector is the ultimate foundation of a region's economic viability--its economic base

Other industries--some examples are restaurants, grocery stores, home construction, mechanics--serve local, not national/global demand. These are the "town fillers," now usually called the "local" or "non-basic" sector

Basically, some industries--think manufacturing, farming, etc., but also film production or high finance--sell their products on national or global markets, bringing money into their local economies. They're the "town builders", which modern scholars call "traded industries" or the "basic sector"

The starting point is Economic Base Theory--a classic concept in economics and geography going back at least to Werner Sombart's 1916 classic "Der moderne Kapitalismus", which made the distinction between "town builders" and "town fillers"

Financial and Transfer Income as Components of the Regional Economic Base Government transfers and financial income form a major component of the basic sector in the United States.

New working paper alert! Posted at @equitablegrowth.bsky.social, it investigates the economic geography of social transfer programs and financial income--with implications for the Medicaid and SNAP cuts proposed in the reconciliation bill 👀

Medicaid and SNAP cuts in congressional Republicans’ budget bill will negatively impact local economies New research shows how cuts to Medicaid and other social programs negatively impact local economies as well as program beneficiaries.

Reductions to essential public programs in the budget reconciliation bill impact more than beneficiaries. They affect key service providers, local businesses, and community stability.
