The objective of this paper is to study equilibrium in a labour market, in which workers search on the job and firms offer wage contracts conditional upon workers' experience and employment status. In this environment, the optimal contract can be described by a promotion contract. The distribution of contract offers is dispersed within and across experience levels. As workers stay longer in the market and promotion dates get closer, the option value of holding a job increases. Firms offer early promotions to attract more experienced workers. A positive relation between experience and earnings can arise purely from firms' optimal response to labour market competition brought about by workers' on-the-job search. We characterise the offer distribution for each experience level and show how these change with labour market conditions. (Copyright: Elsevier)
