“Matthew Kahn has dreamed about buying a climate change retreat. If anybody would know where to go, you’d think it would be an environmental economist who literally wrote the book on which cities will adapt to a warming world and how they’ll do it. But rather than investing in land that’s safe from the risks of coastal flooding, midwestern downpours and crippling drought — Kahn was thinking Bozeman, Mont. — he’s instead settling into a new job in Baltimore, a city that’s expected to be flooding daily by the end of the century.” Read the full article here.

As demand rises for ways to ease the pain of climate change, supply will respond. A growing market for goods prompts producers to innovate—and work by Matthew Kahn of Johns Hopkins University and Daxuan Zhao of Renmin University suggests that the same logic applies to adaptation. Firms researching zero-emission energy and carbon sequestration hope to create a market (or are betting that governments will eventually do the job for them by getting serious about emissions). By contrast the market for better means of coping with climate change is already growing daily. Read the full article here.

Thomas Abt, senior researcher at the Center for International Development, presented the findings of his book Bleeding Out: The Devastating Consequences of Urban Violence — and a Bold New Plan for Peace in the Streets at the Bloomberg School of Public Health on Tuesday.
Abt addressed topics such as the effects of violence on city residents, where the city violence is concentrated and how it can be diminished. He likened treating urban violence to any other kind of disease, saying that both require assessment, diagnosis and treatment. Read the full article here.

With the 2020 census looming, how the city counts Baltimore’s children will be critical to how well we’re able to take care of them.
The U.S. Census Bureau estimates that the 2010 census missed 4.6% of children under age 5, but overcounted people 18 and over by 0.7%. In Maryland, nearly 17,000 children under age 5 were left out of the 2010 census. Census Bureau data suggest that the Maryland undercount was clustered in the counties near Baltimore and DC.
At the Johns Hopkins 21st Century Cities Initiative, we examined what is at stake for the children of Baltimore in the 2020 census. Programs that are vulnerable to child undercount include the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) and the school free breakfast and lunch programs. A large child undercount would also mean that Baltimore would not receive its fair share of federal funds for schools, special education and child care.
8/26/19 – Originally published by NPR’s Marketplace. Listen to the full interview here. ” It’s summer, and that means blockbusters. And for “Marketplace Tech,” it means an occasional look at sci-fi movies and their visions of the future.
In 1985, “Mad Max Beyond Thunderdome” hit the big screen. Mel Gibson and Tina Turner battled in a post-apocalyptic wasteland. You might remember the crazy cars, the eponymous Thunderdome — basically Cirque du Soleil with chainsaws. In the film, fossil fuels are gone. The main energy source is methane from … pig feces.
“Marketplace’s” Jed Kim spoke with Matthew Kahn, an economist at Johns Hopkins University, about the energy technology and economics on display in “Mad Max.” He said that for him, the movie shows how free markets falter in a post-apocalyptic world. The following is an edited transcript of their conversation.” Listen to the full interview here.
8/20/19 – Originally published by Fox News. “Plastic pollution found in the world’s oceans and the melting permafrost in the Arctic could have startling economic burdens, perhaps as much as $2.5 trillion and $70 trillion, respectively. And while there may have been some hope that certain countries could escape the brunt of the impact, a new study suggests that “virtually all” nations will be negatively affected by climate change by 2100. The study, published by the National Bureau of Economic Research, suggests that countries that are warm, cold, rich or poor will all see a significant loss of income if they do not abide by the 2015 Paris Agreement.” Read the full article here.

7/29/19 – Originally published in the Baltimore Sun. “In the last five to 10 years, it would seem as though Baltimore is finally emerging (at least economically) — from its slow, multi-decade decline. But if you’re a resident of one of the city’s poorer neighborhoods, you might not know it… The good news is that for the first time we’ve actually got a group of players primed to make real changes, be it private foundations like Annie E Casey; academic-led alliances like the Johns Hopkins 21st Century Initiative (21CC); local philanthropic organizations like the Baltimore Community Foundation, Living Classrooms Foundation and the Abell Foundation; or impact investing programs from RBC GAM.” Read the full article here.

6/24/19 – Police Departments have long been aware of the correlation between heatwaves and higher crime, but new data measures how poor neighborhoods suffer far more than richer areas. The study by two researchers at the University of Southern California found that on average, overall crime increases by 2.2% and violent crime by 5.7% on days when the maximum temperature is above 85 degrees in Los Angeles.

6/11/19 – The relocation of BB&T’s and SunTrust Bank’s headquarters from Winston-Salem and Atlanta to Charlotte will undoubtedly have an effect on those markets, but how will the other 78 markets where the banks have overlapping branch operations fare? As a follow on to work we have done over the past two years to study trends in small business lending in Baltimore City, we looked specifically at the small business lending performance of these two banks in this single market.
