Figure 2.9: The Effect of Education and Training on Labour Market Outcomes and Inequality

An economy undergoes a technological advancement that uniformly increases the output per worker. If the proportional shares of total income distributed as wages and profits do not change, how will this event affect the shape of the economy's Lorenz curve, which plots the cumulative share of income against the cumulative share of the population (ordered from unemployed, to workers, to owners)?

Productivity and Income Distribution Analysis

A national policy focused on improving education and training is successfully implemented, leading to a significant, economy-wide increase in the output produced per worker. Assuming the proportional division of total income between wages and profits remains unchanged, arrange the following outcomes in the logical causal sequence that describes the effect on income distribution.

True or False: In an economy where income distribution is visualized with a Lorenz curve, if an increase in labor productivity leads to a lower unemployment rate, income inequality will always decrease, regardless of what happens to the proportional shares of income going to wages and profits.

Analyzing the Impact of Productivity on Income Distribution

Explaining Lorenz Curve Shifts from Productivity Gains

An economy experiences a uniform increase in output per worker, while the proportional shares of income going to profits and wages remain constant. Match each component of this economic event with its correct description in the context of the Lorenz curve and income inequality.

An economy is characterized by high income inequality, which is largely attributed to a high rate of unemployment. A government aims to reduce this inequality by lowering unemployment, but without changing the proportional shares of national income that go to wages and profits. Based on the mechanism linking productivity to employment and income distribution, which of the following policy proposals is most likely to be effective in achieving this specific goal?

An economist observes that a country's Lorenz curve, which plots the cumulative share of income against the cumulative share of the population, has shifted. The first kink in the curve, representing the share of the population that is unemployed, has moved to the left. The second kink, representing the cumulative share of the population including both the unemployed and the workers, has remained at the same horizontal position. The overall curve is now closer to the line of perfect equality. Given these observations and assuming the proportional shares of national income going to wages and profits have not changed, which of the following economic events is the most plausible explanation?

An economy experiences a significant increase in labor productivity, which leads to a lower equilibrium unemployment rate. However, contrary to the expected outcome, overall income inequality, as measured by the Gini coefficient, actually increases. This counterintuitive result can be explained by a concurrent and significant increase in the __________.
