Snow Belt to Sun Belt Migration: End of an Era?
Internal migration has been cited as a key channel by which societies will adapt to climate change. We show in this paper that this process has already been happening in the United States. Over the course of the past 50 years, the tendency of Americans to move from the coldest places (“snow belt”), which have become warmer, to the hottest places (“sun belt”), which have become hotter, has steadily declined. In the latest full decade, 2010-2020, both county population growth and county net migration rates were essentially uncorrelated with the historical means of either extreme heat ...

The Postpandemic U.S. Immigration Surge: New Facts and Inflationary Implications
The U.S. experienced an extraordinary postpandemic surge in unauthorized immigration. This paper combines administrative data on border encounters and immigration court records with household survey data to document two new facts about these immigrants: They tend to be hand-to-mouth consumers and low-skilled workers that complement the existing workforce. We build these features into a model with capital, household heterogeneity and population growth to study the inflationary effects of this episode. Contrary to the popular view, we find little effect on inflation, as the increase in supply ...
U.S. Population Growth Slowed Further in 2020
This year will likely be the slowest annual population increase in U.S. history outside of wartime.

Secular Trends in Macroeconomics and Firm Dynamics: A Conference Recap
How does declining population growth affect firm dynamics? Is income growth volatility decreasing in the U.S.? How do changes in housing prices affect young businesses? Have investments in artificial intelligence improved productivity? These were among the questions addressed by economists during a recent Richmond Fed research conference.

From Brain Drain to Brain Gain, Oklahoma’s Population on the Rise
This edition of Oklahoma Economist examines multiple sources of state migration data to quantify the drivers of the state’s population growth. It finds the recent surge of new residents was driven primarily by historic levels of domestic migration from states in the western half of the U.S., as well as a reversal of the “brain drain” that plagued the state for much of the 2010s.

Was China's Housing Boom a Bubble?
This article investigates the factors influencing nationwide and city-level house price trends in China during the 2000s and early 2010s, considering the country’s significant structural transformation and urbanization. The analysis reveals that "fundamental forces" effectively explain house price appreciation at the national level and in most cities, with Beijing and Shanghai being notable exceptions. Income growth is the primary driver of rising house prices, while population growth also plays a significant role. However, in many cases, the impact of population growth on house prices is ...

From Population Growth to TFP Growth
A slowdown in population growth reduces business dynamism by increasing the share of older firms. We explore how this affects productivity growth using a business dynamics model with endogenous productivity. The growth rate of older firms is a key factor in determining the impact of population growth on productivity. Quantitatively, this effect is substantial for both the U.S. and Japan. In the U.S., slowing population growth reduces TFP growth by 0.3 percentage points from 1970 to 2060, with an even larger effect in Japan. However, TFP growth reacts slowly due to short-run counterbalancing ...

From Population Growth to TFP Growth
A slowdown in population growth causes a decline in business dynamism by increasing the share of old businesses. But how does it affect productivity growth? We answer this question by extending a standard business dynamics model to include endogenous productivity growth. Theoretically, the growth rate of the size of surviving old businesses is a “sufficient statistic" for determining the direction and magnitude of the impact of population growth on productivity growth. Quantitatively, this effect is significant across balanced growth paths for the United States and Japan. TFP growth in the ...

Demographics and Real Interest Rates Across Countries and Over Time
We propose that the natural rate of unemployment may have an active role in the business cycle, in contrast to a widespread view that the rate is fairly smooth and at most only weakly cyclical. We demonstrate that the tendency to treat the natural rate as near-constant would explain the surprisingly low slope of the Phillips curve. We observe that evidence is weak about this basic point–the evidence neither comes close to rejecting the conventional view nor does it reject a very different view in which fluctuations in the natural rate are associated with a substantial fraction of cyclical ...
