An introduction to the Solow Model
An introduction to the Solow Model
Mar 17, 2026 11:02 AM

Note: This is post #80 in a weekly video series on basic economics.

The Solow model was named after Robert Solow, the 1987 winner of the Nobel Prize in Economics. Among other things, the Solow model helps us understand the nuances and dynamics of growth, says Alex Tabarrok of Marginal Revolution University. The model also lets us distinguish between two types of growth: catching up growth and cutting edge growth. As you’ll soon see in this video, a country can grow much faster when it’s catching up, as opposed to when it’s already growing at the cutting edge.

(If you find the pace of the videos too slow, I’d mend watching them at 1.5 to 2 times the speed. You can adjust the speed at which the video plays by clicking on “Settings” (the gear symbol) and changing “Speed” from normal to 1.25, 1.5 or 2.)

The spiritual core of liberty
Last week FEE published an essay by economist Dierdre McCloskey titled “The Core of Liberty is Economic Liberty.” McCloskey writes, [E]conomic liberty is the liberty about which most ordinary people care. True, liberty of speech, the press, assembly, petitioning the government, and voting for a new government are in the long run essential protections for all liberty, including the economic right to buy and sell. But the lofty liberties are cherished mainly by an educated minority. Most people—in the long...
Erasing the cross: Public vs. private sector
The European discount grocery chain Lidl stirred controversy by removing the cross from its products’ labels, so as not to give offense. Eagle-eyed consumers noticed that Eirdanous, its Greek food line, featured a picture of a blue-domed Greek Orthodox Church by the sea – but unlike every other such church, its cupola was not topped by a cross. pany Photoshopped the symbol of Christ’s victory over death and Hell off of the Anastasi(in Greek, literally, “resurrection”) Church inSantorini. Perhaps to...

7 Figures: Income and poverty in the U.S.
The U.S. Census Bureau released its latest report on e and poverty in the United States today. Here are seven figures from the report you should know about: 1. Real median household e increased 3.2 percent between 2015 and 2016—from $ 57,230 to $59,039. (This figure surpasses the previous high reached in 1999.) 2.

Upstream: A Conversation on Artist Renee Radell
On the Upstream segment of this week’s Radio Free Acton podcast, I discuss the visual art of Renee Radell with Gregory Wolfe. Radell’s work is the subject of Renee Radell: Web of Circumstance (Predmore Press, 2016, 220 pages, $80), a book presenting a career overview of her artistic efforts. In his review of Web of Circumstance for The University Bookman, Wolfe – founder and editor of Image magazine – determines the panying text by Eleanor Heartney superficial in contrast to...
‘Can people of faith hold public office?’: Transatlantic insights
Believing in a faith, to the point that it impacts one’s views in any way, is increasingly seen as a disqualification for public office. Two recent events raise the possibility that this unofficial employment test is part of a larger, civilizational shift taking place on both sides of the Atlantic. In the UK last week, a firestorm erupted when Conservative MP Jacob Rees-Mogg told Piers Morgan that he believes in the Roman Catholic Church’s teachings on marriage and abortion. (Tim...
Development vs. thuggery: How foreign aid hinders local business
The foreign aid movement has largely failed the global poor, promoting top-down solutions at the expense of bottom-up enterprises and institutions, as Acton’s widely acclaimed documentary, Poverty, Inc., and PovertyCure film series detail at length. Whether due to basic errors in economic thinking or a more subtle, subconscious apathy toward local enterprise, such efforts routinely lead to more disruption than development, hindering the very countries they hope to assist. It’s an ignorance and oversight that has painful implications for many...
The consuming self as tyrant
“Consumerism is, quite precisely, the consuming of life by the things consumed. It is living in a manner that is measured by having rather than being.” -Richard John Neuhaus In a free economy, we each serve distinct roles as both producers and consumers. As producers, we create and serve, leveraging the work of our hands to meet the needs of our neighbors. As consumers, however, we look to ourselves and our own needs. Consumption is good and necessary thing, but...
Hurricanes and price gouging: More from Acton analysts
Following Hurricane Harvey and Hurricane Irma, price gouging has e a hot topic of conversation. The prices of water, gasoline and hotel reservations in places affected by the hurricanes have skyrocketed. Airlines are also facing criticism for their heightened prices, many people claiming that airlines are taking advantage of customers. In a new article published on News-Pressin Fort Myers, Florida, Victor Claar, associate professor of economics at Florida Gulf Coast University, suggests that rise of airline ticket prices may not...
