The mass unemployment in the 1930’s has sometimes been put down to “stick wages”. Fundamentally, the value of labour fell but the price didn’t – leading firms to cut back on employment at a faster rate than would have been socially optimal.
Since then, wage stickiness appears to have eased to some degree: Unions are less powerful than they were, and employees have a greater level of understanding about why firms may have to cut nominal wages – leading to less of a psychological impact (Note: These statements are just conjecture – if you don’t agree with them feel free to state in the comments, we could really do another post on it 🙂 ).
However, does that mean that the underlying issue of labour market adjustment has abated? The short answer is no.
