16) which of these types of unemployment is characterized by peaks of joblessness at specific times of the year? a) seasonal b) cyclical c) frictional d) structural

The correct answer is A. Seasonal.

Definition: Seasonal unemployment is one that is related to activities that are concentrated at certain times of the year (for example, holidays, summer, harvest, etc.) while the rest of the year activity is very low or non-existent.

The main characteristics of seasonal unemployment are:  

1. Foreseeable: it is known what, when, and how fluctuates a certain activity during the year, so it is possible to foresee that unemployment will increase at a certain time of the year.

2. Short-term contracts: temporary contracts are used in most economic sectors with a marked seasonality. This way, the demand for workers during the period of greatest activity without a long-term commitment is covered.

3. Need to save and plan: people who work in sectors susceptible to high seasonal unemployment must save at work periods to better face with the months of unemployment.
