In general terms, macroeconomics measures the aggregate performance of a nation\u2019s economy. It is made up of several related \u201cmarkets\u201d within a country: the goods and services market (which determines output and the price level\/inflation), the labour market ((un-) employment and the wage rate), the money (bond) market (interest rates), and the foreign exchange market (trade balance and currency exchange rate). Often, when we wonder whether or not our national economy is doing well or poorly, we look to these macroeconomic markets for indicators.<\/p>\n

The pervasive nature of climate risk means that every aspect of the macroeconomy is vulnerable. Recession, high unemployment, price volatility, declining productivity\u2014these are all potential outcomes as climate risks materialize.<\/p>\n

Supply-side shocks arising from climate-related hazards (like price volatility, damage to the capital stock, falling labour productivity) can increase the costs of economic output, creating inflationary pressures in affected areas of the economy. Demand-side shocks (e.g., through loss of personal wealth, or investment uncertainty) can create recessionary pressures.<\/p>\n
