The Unassuming Economist

From a new paper by Ning Jia, Raven Molloy, Christopher Smith, and Abigail Wozniak:

“Internal migration patterns in the US have drawn growing attention among researchers, policy analysts, and others. This interest has been driven by two trends. First, internal migration in the US has fallen for more than three decades (Molloy et al. 2011; Frey 2009; Cooke 2011, 2013). This decline raises questions about whether it stems from desirable factors, like improved location or job matching, or undesirable factors, like employer monopsony power or other barriers to job mobility (Kaplan and Schulhofer-Wohl 2017; Molloy et al. 2016). Relatedly, highly educated Americans have become increasingly concentrated in larger cities (Diamond 2016). Thus, both the level of migration in the US and the types of destinations chosen by different types of people have changed in important ways over the last several decades.

(…)

Dao et al. (2017) revisit the key ideas from BK and show more directly that the nature of local labor market adjustment to demand shocks has changed in the last few decades—and that the diminished responsiveness of net migration is a key reason for the change in how local labor markets adjust. The authors take a similar approach to BK by estimating adjustment margins at the state level’s response to demand shocks. However, they extend the BK sample with an additional 20 years of data and make other methodological innovations, including using administrative data on migration flows instead of inferring population adjustment from CPS-based measures. Among the many useful contributions of this analysis is a demonstration that after 1990, the net migration response to a state-level demand shock has been smaller on average than in earlier periods, and the response of the unemployment and labor force participation rates is larger. Hence, one way to reconcile the BK findings with the more recent conflicting evidence on local labor market adjustment and regional divergence is that migration was more important as an equilibrating mechanism from the 1970s through the early 1990s (the period in the BK sample) and has recently become less important.”

“The Issue:

The price of housing has a special importance because housing is both a basic necessity and a key component of wealth. Around the start of the pandemic, some experts predicted a protracted collapse in housing prices and the housing market. For example, in April 2020 the staff at Freddie Mac projected home prices would fall by 0.5 percent over the next year. In fact, the opposite happened: The Case Shiller National Home Price Index rose by 15 percent between April 2020 and April 2021 while home sales hit a 15 year high in the calendar year 2021. This stands in stark contrast to the Great Recession when the price index fell 44 percent between May 2007 and May 2009. But one similarity across the Great Recession and the COVID downturn is the wide differences in housing price changes across different parts of the United States. What has happened to housing prices during the COVID pandemic and why?  And what are the broader economic implications of this?

The Facts:

House sales and housing construction fell at the outset of the pandemic in March 2020. The total housing inventory on the market, including newly constructed houses and those being resold, was down 10.2 percent between March 2019 and March 2020. Between February 2020 and March 2020 housing starts declined by 22.3 percent, perhaps reflecting builders’ bleak expectations for future demand. Total existing-home sales fell 8.5 percent in March 2020 compared with the prior month and tumbled a further 17.8 percent in April.”

Historically, the number and wages of women in the labor force grew at a significant pace during the 1970s and 1980s but began stalling in the early 1990s, especially for college graduates.

In this paper, the authors have argued that this discontinued growth since the 1990s is a consequence of growing inequality. They show that slowdown in participation and wage growth was concentrated among women married to highly educated and high-income husbands, whose earnings grew dramatically over the period under study. Through a model of household labor supply, they qualitatively analyze the above-mentioned effect and account for the rise in the gender wage gap for college graduates.

In this recent blog, author Timothy Taylor discusses the perplexing question of slowing agricultural growth witnessed in several countries across the world in the past couple of years. He first analyzes what percentage of influence on agricultural growth is exerted by rising overall economic productivity in the country, and discovers that it is mostly low-income countries where the decline has been most profound. The column also provides explanations for this trend that are worth exploring.

“Lockdowns resulting from the COVID-19 pandemic reduced overall energy demand in 2020. However, electricity generation from renewable sources was surprisingly resilient and, as a result, the share of renewables in electricity demand increased in many regions (International Energy Agency 2020). What remains an open question is whether recessions of themselves tend to spur investments in more efficient, greener, energy sources, or instead to continue investing in old coal-based plants. On one hand, the disruption in financing engendered by the crisis may reduce innovation through lower research and development, which is highly procyclical (De Haas et al. 2021). On the other, lower energy demand and associated plant closures brought about by the recession may provide energy producers with an opportunity to improve their efficiency by replacing older environmentally unfriendly plants with renewable sources of energy when demand recovers. The idea that outdated units are destroyed and replaced by newer technological innovations goes back to Joseph A. Schumpeter’s thesis on ‘creative destruction’ (Schumpeter 1939, 1942), with economic disruptions such as the one brought about by the pandemic acting as a time of cleansing (Caballero and Hammour 1994).”
