New on FinoLib, my finance education website: I have published an article called Purchasing Power Parity Explained: Balance of Payments and Tariffs, from Volume I: Global Economy. Here is what the article explains, written as a short expert briefing; the full piece, with every worked example, is one click away.
1.12 Unemployment and the Labor Market
The idea in plain words
The unemployment rate is the share of the labor force that is jobless and actively looking for work. People who have stopped looking leave the labor force and show up in the participation rate instead. The gap between the headline U-3 and the broader U-6 is a quick measure of slack.
Key points
■In September 2026 U-3 was 4.2% and U-6 was 7.6%; the participation rate was 61.8%, and employers added only 29,000 jobs.
■Maximum employment is half of the Fed’s dual mandate, so unemployment data directly drives its interest rate decisions.
A closer look
The labor force is everyone who is either currently working or actively looking for work. The unemployment rate is the percentage of the labor force currently without a job but actively seeking one. People who have stopped looking entirely have left the labor force altogether — they are not counted as unemployed, but their absence is tracked separately through the labor force participation rate.
1.13 Balance of Payments — The Complete Money-Flow Picture
The idea in plain words
The balance of payments records every flow across a border, and it always balances: a current account deficit is financed by inflows in the financial account or by the central bank selling reserves. India’s 2025-26 ledger shows why the trade deficit alone misleads.
Key points
■India ran a merchandise trade deficit of $337.3 billion in 2025-26, offset by $312.0 billion of net services, remittance and income flows.
■That left a current account deficit of about $25.2 billion, only 0.6% of GDP.
A closer look
The trade balance (exports minus imports) is just one slice of the financial flows between a country and the rest of the world. The balance of payments is the complete record of every financial flow into and out of a country — not just trade in goods and services, but also investment flows, remittances, and financial transfers of all kinds.
1.14 Purchasing Power Parity — Why GDP Rankings Deceive
The idea in plain words
Market-rate GDP converts a country’s output into dollars at exchange rates. Purchasing power parity prices the same output at common international prices, which says more about living standards and real scale. India is sixth at market rates but third by PPP.
Key points
■By PPP India’s economy was about $17.3 trillion in 2025, against roughly $7.2 trillion for fourth-placed Russia and $7.0 trillion for Japan.
■At market rates the 2025 order was the US ($30.8 trillion), China ($19.6 trillion), Germany ($5.0 trillion), Japan ($4.4 trillion), the United Kingdom ($4.0 trillion) and India ($3.9 trillion).
A closer look
When headlines rank economies by GDP, they usually convert each country’s output into US dollars at market exchange rates. But exchange rates reflect trade and capital flows, not local living costs. A haircut in Mumbai and a haircut in Manhattan are the same service, yet the Manhattan one might cost many times more in dollar terms. Market-rate GDP therefore systematically understates the real size of economies where local prices are low — which is most developing economies.
1.15 Demographics — The Slowest, Strongest Force in Economics
The idea in plain words
Countries with many young workers and few dependents get a growth tailwind called the demographic dividend. Countries that grow old before they grow rich lose it. India’s window is widest between now and roughly the 2040s.
Key points
■Japan’s population has been shrinking since around 2010, with about 30% of its people aged 65 or older in 2025, and China’s began declining in 2022.
■India’s median age is around 28–29, against roughly 39 in China and the US and 49 in Japan.
1.16 Tariffs, Trade Wars, and the Age of Friend-Shoring
The idea in plain words
A tariff is a tax on imports. It shields local producers but raises prices for local consumers. After decades of falling tariffs, the years from 2018 to 2026 reversed the trend, and companies began arranging supply chains around politics as well as cost.
Key points
■“China + 1” means multinationals keep Chinese operations but add a second manufacturing base elsewhere; India, Vietnam and Mexico are the biggest “+1” winners.
■The Smoot-Hawley Tariff Act of 1930 brought worldwide retaliation, and global trade collapsed by roughly two-thirds during the Great Depression.
