Developed economies typically have jobs that require specialized skills and knowledge in industries like services, technology, and finance. Unemployment in developed economies can be structural when workers' skills do not match available jobs, cyclical during economic downturns when demand decreases, or seasonal in industries like tourism that fluctuate with the seasons. High youth unemployment is a major problem in some Mediterranean countries due to the sovereign debt crisis, with over 50% of young workers unemployed in Greece and Spain.
