Final answer:
Country ABC did not experience a recession in 2019, as there was no decline in GDP for two consecutive quarters. Instead, GDP increased from Quarter 1 to Quarter 2 before declining in subsequent quarters.
Step-by-step explanation:
Based on the standard definition of a recession, which is typically characterized by a decline in Gross Domestic Product (GDP) for two consecutive quarters, country ABC did not experience a recession in 2019. Despite seeing its GDP decline in the later quarters of the year (Quarter 3 and Quarter 4), there was no occurrence of two consecutive quarters of decline at the start of the year; GDP increased from $390 billion in Quarter 1 to $400 billion in Quarter 2.
Moreover, the understanding of a recession does not solely rest on GDP figures. Other economic indicators such as unemployment, inflation, or interest rates also provide a comprehensive view of an economy's health and its deviations from potential GDP. For example, during the COVID-19-induced recession, despite a rapid drop in real GDP, the economy quickly bounced back, and real GDP had slightly surpassed pre-pandemic levels by Quarter 1 of 2021.
