internal labour market การใช้

• A neglected aspect of Pigou's work is his analysis of a range of labour-market phenomena studied by subsequent economists, including collective bargaining, wage rigidity, internal labour markets, segmented labour market, and human capital.
• Due to the European Union's in principle single internal labour market policy, countries such as Italy and the Republic of Ireland that have seen relatively low levels of labour immigration until recently ( and which have often sent a significant portion of their population overseas in the past ) are now seeing an influx of immigrants from EU countries with lower per capita annual earning rates, triggering nationwide immigration debates.
