L-shaped recovery

Topic: Economic Growth Theories and Business Cycles · NCERT: Beyond NCERT

Meaning

An L-shaped recovery is a recovery in which output falls steeply and then stays low for many years. Growth may start again, but it stays weak. Output never climbs back to the path it was on before the crisis (its old trend, meaning the path the economy would have followed in normal times). So the loss of output is permanent.

It matters because it is the worst of the recovery shapes. A crisis that could have been temporary ends up lowering the economy's ability to produce for a long time. Knowing this shape helps you judge whether a "recovery" is real, or only a bounce in growth numbers.

Explanation

How the L-shape forms

• The fall (the vertical stroke of the L): a crisis causes a steep fall in real GDP (output measured at constant prices).
• The flat base (the horizontal stroke): after the lowest point (the trough), output does not bounce back.
• Output may grow again, but slowly.

• The gap between actual output and the old trend does not close. It may even get wider.

• Two tests decide the shape:

• Does output return to its pre-crisis level?
• Does output return to its pre-crisis trend (where it would have been with no crisis)?

• In an L-shape, the answer to the trend question is always no.

• Growth theory view:

• Solow (1956): after a temporary shock, the economy returns to its steady-state growth path (the long-run path where growth comes only from technology and labour). In this model, a V back to trend is the "normal" result.
• An L-shape breaks this rule. It happens when the shock damages the economy's ability to produce, so the trend line itself moves down.

Why the trend line moves down: scarring and hysteresis

• Scarring means long-lasting damage to the economy's ability to produce:
• workers lose jobs, and then lose skills while they are unemployed;
• firms shut down, especially small ones;
• investment is lost, so the economy has less capital (machines, factories);

• children lose schooling, so future workers are less skilled.

• Hysteresis means a temporary shock causes a permanent loss in the output level. The trend line shifts down, so the graph looks like an L (or a swoosh), not a V.

• The Harrod-Domar channel. Harrod-Domar (1940s) gives the growth rate as g = s / v:
• s = saving rate.
• v = capital-output ratio (how many units of capital are needed to make one unit of output).
• Crisis → saving falls → less investment → less capital added → output grows more slowly for years.
• Worked example: with s = 30% and v = 4, g = 30 ÷ 4 = 7.5%. If the crisis pushes s down to 24%, g = 24 ÷ 4 = 6%. Growth stays lower year after year. That is the flat base of the L.

Worked example: level recovered, trend lost

The study note uses these example figures to show why an L-type trend loss can hide behind good-looking growth numbers:

• Pre-crisis GDP = 100.
• Year 1: growth of −6% → 100 × 0.94 = 94.
• Year 2: growth of +9% → 94 × 1.09 = 102.46. This is only about 2.5% above the starting level.
• Old trend at 6% a year: 100 → 106 → 112.36.
• Output gap (the distance between actual output and the trend) = 112.36 − 102.46 ≈ 9.9. Output is about 9% below trend.
• Base effect: the +9% looks big only because it is measured on a smaller base (94, not 100).
• Lesson: if growth then settles below the old rate, this gap never closes. The graph becomes an L.

What makes an L-shape more likely

• Asset-price crash plus bad loans. In Japan after 1990, asset prices collapsed and banks held bad loans (loans unlikely to be repaid).

• Banks with bad loans lend less → firms invest less → growth stays weak.

• Deflation (a continuous fall in prices). This was also seen in Japan after 1990.

• Prices keep falling → people delay buying → demand stays weak → firms cut output.

• Early fiscal tightening. In Greece after 2010, a debt crisis was followed by austerity (deep cuts in government spending).

• Government spends less → total demand falls further → output and jobs fall more.

• Deficient demand (total spending lower than what the economy can produce at full employment). This is the Keynesian lesson from the Great Depression (1929 onwards): weak demand can keep output low for a long time unless the government and the central bank support demand.

In India

• No official L-shape, but a clear trend loss. India's COVID-19 path shows how a "V" in growth rates can sit alongside an L-type loss against the trend.
• The fall:
• Q1 2020-21 (April-June 2020): GDP fell by 23.9% because of the national lockdown [1].
• Q2 2020-21 (July-September 2020): GDP fell by 7.5% [1].

• Full year 2020-21: real GDP contracted by 5.8% [5][6].

• The official view (V-shape): the Economic Survey 2020-21 (January 2021) said a "V-shaped recovery" had begun from July 2020. It projected real GDP growth of 11% for 2021-22 [1].

• The rebound: real GDP grew by 9.1% in 2021-22 (First Revised Estimates, February 2023) [5][6]. Real GDP was ₹136.87 lakh crore in 2020-21 and ₹149.26 lakh crore in 2021-22 [6].
• The L-type warning:
• At the Provisional Estimate stage (May 2022), real GDP in 2021-22 was only 1.5% above the 2019-20 level [4].

• So two years of growth were almost fully lost. The level of output recovered, but the old trend was not regained.

• Who measures it: the NSO/MoSPI releases GDP estimates. These are revised several times. For example, the 2021-22 growth figure moved from 8.7% (Provisional Estimates, May 2022) to 9.1% (First Revised Estimates) [4][5].

• Policy to stop scarring:
• ECLGS (Emergency Credit Line Guarantee Scheme): launched in May 2020 under the Aatmanirbhar Bharat Abhiyan to help MSMEs and other businesses pay their costs and restart [3].
  • The government guarantees the loan. If the borrower does not repay, the government covers the bank's loss.
  • So banks lend more readily to small firms. This keeps firms alive and avoids permanent closures.
  • Guarantees of ₹3.61 lakh crore were issued, benefiting 1.19 crore borrowers (as of 31 January 2023) [2].
• RBI: cut the repo rate (the interest rate at which the RBI lends money to banks for a short time), gave a loan moratorium (borrowers could delay repayments without being marked as defaulters), and ran TLTRO (long-term funds to banks, meant for specific stressed sectors).

Don't confuse with

• V-shaped recovery: output returns quickly to both the pre-crisis level and the trend. An L-shape never regains the trend.
• U-shaped recovery: output stays at the bottom for a while but does return to trend in the end (example: US 1973-75). An L-shape never does.
• Swoosh recovery: a sharp fall, then a slow but steady climb. The loss is recovered over several years. An L-shape stays flat and the loss is permanent.
• K-shaped recovery: this describes how the recovery is shared (some sectors and groups rise, others fall). It says nothing about how deep the fall is. An L-shape describes the path of total output.

Prelims Hooks

• L-shaped recovery: a steep fall followed by long stagnation. Output never regains its old trend, so the output loss is permanent.
• Classic examples: Japan after 1990 ("lost decade": asset crash, bad loans, deflation) and Greece after 2010 (debt crisis followed by austerity).
• Hysteresis: a temporary shock causes a permanent loss in the output level, so the trend line moves down. This is the cause of an L or swoosh shape.
• Solow (1956) predicts a return to the steady-state path after a temporary shock (a V). Harrod-Domar: g = s / v, so lower saving after a crisis means slower growth for years.
• Trap: a high growth rate after a fall does not mean lost output is recovered. −6% followed by +9% leaves output only about 2.5% above its starting level and below the old trend.
• Trap: the Economic Survey 2020-21 called India's recovery V-shaped, not L-shaped [1]. Also, ECLGS is a government guarantee on bank loans, not a direct grant [3].

Mains Points

• Policy mistakes can turn a temporary shock into a permanent one:
• The Solow model predicts a return to trend. But Japan (deflation, bad loans) and Greece (austerity) show that weak demand plus early spending cuts can produce an L-shape.

• This supports counter-cyclical policy (the government spends more in bad times and less in good times) over early fiscal tightening.

• India: level recovered, trend lost:

• Real GDP in 2021-22 was only 1.5% above 2019-20 [4], so two years of growth were almost fully lost.
• Scarring (lost skills, closed MSMEs, lost schooling) may lower potential growth (the fastest the economy can grow without causing inflation) and push India towards an L-type path.

• This supports public capital spending ("crowding-in", where government investment encourages private investment) and MSME credit support.

• Credit guarantees vs cash transfers (GS-III fiscal trade-off):

• ECLGS reached 1.19 crore borrowers with ₹3.61 lakh crore of guarantees (January 2023) [2], at a low upfront cost to the budget. It kept firms alive and reduced scarring.
• Critics argue that credit cannot help households that have lost income. Weak mass demand → firms delay investment → growth stays low. They say direct transfers would have raised demand faster and made an L-shape less likely.
