The Short-time Working App


Welcome to this app, where you can explore the effects of short-time working policies! You will see changes in income distribution, after adjusting values of the following two sliders:

• a certain proportion of the working population that works less than normal ("percentage of people with reduced working hours")

• the amount of cut in working hours ("percentage loss of working hours"), thus making people subject to partial or complete loss of their incomes

Note that under short-time working policies, the government provides partial compensations for lost wages. So if you work only 30% of your regular working hours, you will get more than just 30% of your regular income. More on that below.

In the plot you can see two histograms. They correspond to the income distributions with (orange) and without (blue) the effect of short-time working, according to the values of the parameters you choose. In addition, the poverty lines of both distributions (which are defined as 60% of the respective median incomes [1]) and their corresponding poverty rates (i.e., percentages of the population with an income below the respective poverty lines) are displayed.

And now, have fun exploring!

Additional Information

Short-time working is a governmental policy designed to support companies that are going through economic hardships. When employees experience reductions in working hours, companies only need to pay for the hours that they work. Then, the government provides partial compensations for their lost wages [5]. This policy reduces the number of bankruptcies, the extent of unemployment and the increase in poverty. In this interactive app, we will examine the impacts of short-time working on incomes and poverty in Germany, where this government policy is called "Kurzarbeit". Since short-time working involves many complicated matters, such as taxation and family status, we set up assumptions and rules to simplify the subject matter. You can read more on that below.

We simulated incomes of 50,000 individuals in 2019 and regard each of them as a single-person household. We do not include any top 3% incomes, as people making such money would be unlikely to fall into poverty. Besides, these incomes follow a probability distribution (the "Pareto distribution") that is beyond the scope this course [2]. Incomes below the Minijob threshold of 450 Euros per month are not discussed here as well, because they are not subject to short-time work compensations. An important underlying assumption of this simulation is that there is no additional governmental assistance for households with low incomes. For the sake of simplicity, we assume that everyone affected by short-time work experiences the same amount of loss of working hours.

In Germany, short-time working is applicable only when people experience more than 10% loss in wages [5]. We assume that people are paid by the number of working hours solely, and therefore the amount of lost working hours becomes an indicator of when a person starts short-time working. Single-person households initially receive 60% of the lost net income as additional compensations. The rate increases starting from the fourth month of short-time working [5]. In this example, we focus on the first three months. Short-time working compensations are closely related to how income taxes are calculated. We reduced the complexities of German income taxes by simplifying the tax brackets and setting income amount as the sole determinant of income taxes.

As you adjust the parameters, you will notice the appearance of spikes in the income distributions. This is completely normal, because not every income group is affected by short-time working to the same extent.
