Frictional Unemployment
Frictional unemployment is a type of short-term unemployment that occurs when workers look for new employment or transition out of old jobs and into new ones. This temporary period of unemployment is the result of voluntary transitions within an economy. It stands in contrast with structural unemployment, which stems from economic shifts that make it difficult for workers to find work.Frictional unemployment can be evident in a growing, stable economy and is regarded as a part of natural unemployment, the minimum unemployment rate in an economy due to economic forces and the movement of labor.The frictional unemployment rate is calculated by dividing the workers actively looking for jobs by the total labor force. The workers actively looking for jobs are typically classified into three categories: workers who left their job, people returning to the workforce, and new entrants.

Lindahl Equilibrium
A Lindahl equilibrium is a state of equilibrium in a market for public goods. As with a competitive market equilibrium, the supply and demand for a particular public good are balanced. So are the cost and revenue required to produce the good.The equilibrium is achieved when people share their preferences for particular public goods and pay for them in amounts that are based on their preferences and match their demand.Public goods refer to products and services that are provided to all by a government and funded by citizens' taxes. Clean drinking water, city parks, interstate and intrastate infrastructures, education, and national security are examples of public goods.A Lindahl equilibrium requires the implementation of an effective Lindahl tax, first proposed by the Swedish economist Erik Lindahl.
