The International Monetary Fund defines a global recession as "a decline in annual per‑capita real World GDP (purchasing power parity weighted), backed up by a decline or worsening for one or more of the seven other global macroeconomic indicators: Industrial production, trade, capital flows, oil consumption, unemployment rate, per‑capita investment, and per‑capita consumption".
In a 1974 New York Times article, Julius Shiskin suggested several rules of thumb to identify a recession, which included two successive quarterly declines in gross domestic product (GDP), a measure of the nation's output.
In the United States, the National Bureau of Economic Research (NBER) is regarded as the authority which identifies a recession and which takes into account several measures in addition to GDP growth before making an assessment.
[10] According to the IMF, the real GDP growth of the emerging and developing countries is on an uptrend and that of advanced economies is on a downtrend since the late 1980s.
Countries in East Asia (including China) have suffered smaller declines because their financial situations are more robust.
