It asks such questions as 'are the low-paid stuck at the bottom of the earnings distribution or do they move up?', 'for how long do people stay low paid?' and 'what is the relationship between pay and employment?'. For while we know that earnings inequality has widened remarkably over the past 20 years, we know rather little about the dynamics of the earnings distribution. This report tries to fill some of that gap in our knowledge. Pay and Employment Only about two-thirds of men (aged between 18 and 60 and not in full-time education) remained in continuous employment over the whole period from 1991 to 1994, while fewer than 9 per cent were out of work all the time. The rest spent some of the time in work and some of the time in unemployment. Importantly, we also find that lower relative wages of individuals are associated with a higher probability that they will move out of work in the future. Among men, 30 per cent of those starting in the bottom quarter of the wage distribution spent some time out of work in the next two-and-a-half years (Table I). This was true of just 12 per cent of those starting in the top quarter of the distribution. Similarly, looking at transitions into work, 56 per cent of the men moving out of unemployment moved into a job with wages in the bottom quartile of the distribution.

Employment Changes and Wage Changes We are not just seeing 'churning' between low pay and unemployment during the 1990s. It is also the case that movements into and out of work are associated with substantial wage changes. Table 2 shows that. of those men who moved out of work and then back in again.

On the other hand. three in ten of them experienced wage increases of 20 per cent or more. Mobility and the Minimum Wage One important issue associated with wage mobility is how it alters the number of people who would be affected by a minimum wage. We know how many people would be affected by a minimum wage at any point in time, but the numbers affected over a longer period will depend on how many people move onto and off low pay. Suppose we take half male median earnings as a possible level for a minimum wage. On this basis, something like 7 per cent of employed men and 28 per cent of employed women would be paid the minimum wage at any point in time. But over the period between 1991 and 1994, 12.5 per cent of men and 42 per cent of women, who were in work at some point, would have been affected at one time or another. The numbers vary according to the exact level at which a minimum is placed but the pattern is clear. Substantially more people are affected over just a three-year period than are affected at any one time, as a direct consequence of the degree of wage and employment mobility. Churning between low pay and unemployment means that a minimum wage will appear to be more redistributive in terms of income measured over a few years than in terms of income measured at one point in time. Those currently unemployed might benefit from a minimum-wage job at some time in the future. This, of course, is provided a minimum wage is set at such a 3 Dynamics of low pay and unemployment level that it does not affect the probability of the unemployed getting a job in the future. Persistence of Low Pay Relatively few people make it out of the bottom reaches of the earnings distribution into the top half. Of men who were in the bottom quarter of the earnings distribution in 1991, half were still there in 1994 and a further 13 per cent were out of work altogether. Just 6 per cent had made it into the top half of the earnings distribution. Among women, there was slightly more mobility into the top half of the distribution and much more movement out of work. The figures for men and women who started in the bottom two quartiles of the wage distribution are summarised in Table 3. Continuing Effects of Low Pay and Unemployment Of those men who were low-paid in 1991, defined as earning less than £5 an hour, using usual statistical techniques we would predict that about 31 per cent would be low-paid in 1992. But if we take into account the fact that they were low-paid in 1991 in predicting their status in 1992, we find we would predict that 68 per cent of them would be low-paid in 1992.
