This paper provides new evidence on the causal effect of shortening the duration of pre-university education on long-term labour market outcomes in Ghana. We use the education reform of 1987 as a natural experiment, which reduced the years of education prior to university from 17 to 12 years. Our identification strategy uses a regression discontinuity design, taking advantage of the situation that pre- and post-reform birth cohorts entered the labour market around the same time, thus facing similar conditions.

大学预科教育的持续时间和劳动力市场结果：来自加纳准实验的证据

本文提供了关于缩短大学预科教育时间对加纳长期劳动力市场结果的因果影响的新证据。我们将1987年的教育改革作为一个自然实验，将大学前的受教育年限从17年减少到12年。我们的识别策略使用回归不连续性设计，利用改革前后出生队列大约在同一时间进入劳动力市场的情况，因此面临类似的情况。
