Robert Lucas on the voluntary and involuntary unemployment distinction

Robert Lucas in a famous 1978 paper argued that all unemployment was voluntary because involuntary unemployment was a meaningless concept:
“The worker who loses a good job in prosperous time does not volunteer to be in this situation: he has suffered a capital loss. Similarly, the firm which loses an experienced employee in depressed times suffers an undesirable capital loss.
Nevertheless the unemployed worker at any time can always find some job at once, and a firm can always fill a vacancy instantaneously. That neither typically does so by choice is not difficult to understand given the quality of the jobs and the employees which are easiest to find.
Thus there is an involuntary element in all unemployment, in the sense that no one chooses bad luck over good; there is also a voluntary element in all unemployment, in the sense that however miserable one’s current work options, one can always choose to accept them.”
I agree that we all make choices subject to constraints. To say that a choice is involuntary because it is constrained by a scarcity of job-opportunities information is to say that choices are involuntary because there is scarcity. Alchian said there are always plenty of jobs because to suppose the contrary suggests that scarcity has been abolished.
Lucas elaborated further in 1987 in Models of Business Cycles:
A theory that does deal successfully with unemployment needs to address two quite distinct problems. One is the fact that job separations tend to take the form of unilateral decisions – a worker quits, or is laid off or fired – in which negotiations over wage rates play no explicit role.
The second is that workers who lose jobs, for whatever reason, typically pass through a period of unemployment instead of taking temporary work on the ‘spot’ labour market jobs that are readily available in any economy.
Of these, the second seems to me much the more important: it does not ‘explain’ why someone is unemployed to explain why he does not have a job with company X. After all, most employed people do not have jobs with company X either. To explain why people allocate time to a particular activity – like unemployment – we need to know why they prefer it to all other available activities: to say that I am allergic to strawberries does not ‘explain’ why I drink coffee.
Neither of these puzzles is easy to understand within a Walrasian framework, and it would be good to understand both of them better, but I suggest we begin by focusing on the second of the two.

I do admire the way in which the USA has been able to have a steadily falling equilibrium unemployment rate since 1984 through thick and thin. The Great Recession had no impact on the US equilibrium unemployment rate. Not only has the largest member been able to do this, the OECD host country (red squares) has had a pretty steady natural unemployment rate too all things considered.

I will outsource to Brian Easton, the CTU, the CTU’s Bill Rosenberg and Closer Together Whakatata Mai – reducing inequalities because the continual correction of Max Rashbrooke on poverty and inequality is becoming tiring.

Inequality has not risen for at least 20 years as Bill Rosenberg tweeted. The rise in inequality in the late 1980s and early 1990s was followed by an employment boom that lasted to 2009.
Unemployment was as low as 3 1/2% for several years despite a large increase in labour force participation. Furthermore, the gender wage gap in New Zealand fell rapidly to now be the smallest in any industrialised country.
As the Facebook photos show, there has been strong income and wage growth despite the grizzling of the left. The return of income growth and wages growth after 20 years of real wage stagnation followed the economic reforms of the 1980s and the passage of the Employment Contracts Act in 1991.
As the CTU shows below, the economic reforms in the 1980s put an end to a sharp decline in the relative economic performance of the New Zealand economy.
