Here is an excerpt summary of the research article -The research examines several research studies that look at unemployment trends and factors across different countries. These include studies on the impact of hiring/firing regulations, differences in unemployment rates by gender, the rise of unemployment over time, and the effect of financial crises on youth unemployment. – One study finds that stricter hiring/firing regulations moderately increased unemployment in developing countries from 1992-2008. Other limitations of objective indicators are that they cannot capture how employers judge regulation strictness.- Research on 15 European countries found evidence to reject hysteresis (permanent effects of shocks) for gender unemployment rates when allowing for structural breaks and cross-sectional dependence. Results depended on analytical approach.- Studies have explored factors influencing differences in unemployment rates between countries, like demand shocks, government policies, tax/benefit systems, labor market institutions, and societal characteristics. More “corporatist” systems responded more efficiently.- Financial crises appear to have larger and more long-lasting impacts on youth unemployment rates compared to overall unemployment. High youth unemployment persists long-term in some hard-hit countries.- Contextual factors like human resource practices and country unemployment rates influence the relationship between age and perceived employability. Higher unemployment weakens this relationship.
