There are more informal workers than formal workers across the globe, and yet there remains confusion as to what makes workers or firms informal and how to measure the extent of it. Informal work and informal economic activities imply large efficiency and welfare losses, in terms of low productivity, low earnings, sub-standard working conditions, and lack of social insurance coverage. Rather than quibbling over definitions and measures of informality, it is crucial for policymakers to address these correlates of informality in order to mitigate the negative efficiency and welfare effects.

Since 1991, the Australian economy has experienced sustained economic growth. Aided by the commodities boom and strong public finances, the Australian economy negotiated the global financial crisis without falling into recession. Over this period there were important structural changes, with increasing labor force participation among the elderly and the continuing convergence of employment and unemployment patterns for men and women. However, some recent negative trends include a rise in unemployment, especially long-term unemployment, a deteriorating youth labor market, and a stagnant gender earnings gap.

The economic crisis in the early 1990s brought about a dramatic increase in unemployment and a similar decrease in labor force participation. Unemployment declined afterwards, but stabilized at around 6–7%—more than twice as high as before the crisis. Today, the unemployment rate is lower than the EU average, though Sweden no longer stands out in this respect. The 2008 financial crisis had small effects on the Swedish labor market. Employment in industry declined sharply and then remained stagnant, but employment in the service sectors has continued to grow steadily.

From 2001 to 2015, Brazil experienced a profound reduction in income inequality. The commodities boom and some institutional changes in the early 2000s kick-started the Brazilian labor market, increasing the quantity of formal jobs and earnings, especially for the poorest workers. Significant increases in average schooling and the real minimum wage helped reduce ethnic, gender, and regional earnings gaps, though all remain rather high. However, since 2014 a major fiscal crisis has negatively affected GDP and the labor market, seriously threatening these achievements.
