> Global supply chain disruptions following the onset of the COVID-19 pandemic contributed to the rapid rise in U.S. inflation over the past two years. Evidence suggests that supply chain pressures pushed up the cost of inputs for goods production and the public’s expectations of higher future prices. These factors accounted for about 60% of the surge in U.S. inflation beginning in early 2021. Supply chain pressures began easing substantially in mid-2022, contributing to the slowdown in inflation.

> The causes of the housing supply crisis are widely understood. After the Great Recession, new home construction dropped like a stone. Fewer new homes were built in the 10 years ended 2018 than in any decade since the 1960s. By 2019, a good estimate of the shortage of housing units for sale or rent was 3.8 million. The pandemic-induced materials and labor shortage exacerbated the trend, however, as evidenced by the surge in rents and home prices in 2021.

> Corporate profits rose quickly in 2021 along with inflation, raising concerns about corporations driving up prices to increase profits. Although corporate profits indeed contributed to inflation in 2021, their contribution fell in 2022. This pattern is not unusual: in previous economic recoveries, corporate profits were the main contributor to inflation in the first year and displaced by costs in the second year.
