"Every economy operates under some kind of friction."
This quote by Dale T. Mortensen highlights that no economic system is flawless or frictionless. Frictions refer to factors like transaction costs, market imperfections, information asymmetries, and time lags that influence the functioning of an economy. Understanding these frictions helps us design better policies and strategies, as they have a significant impact on efficiency, productivity, and overall economic growth. In essence, it's important to recognize and address these 'frictions' in order to improve economic performance.
"The labor market is unique because it includes a search process."
The quote highlights that the labor market differs from other markets due to its inherent "search process." In most traditional markets, buyers find sellers through price signals (for example, prices of goods in a store). However, in the labor market, job seekers (buyers) and employers (sellers) must actively search for each other, which adds an element of uncertainty and complexity. This search process affects wages, employment levels, and economic stability as a whole.
"In labor markets, individuals are often uncertain about job opportunities and their own skills."
This quote emphasizes that in job markets, people may not have a clear understanding of available job opportunities or their own abilities. The uncertainty can stem from various factors such as lack of information, rapid changes in the job market, and personal doubts about one's qualifications. This uncertainty can lead to challenges in finding suitable employment and making informed career decisions.
"Market clearing is an idealization rather than a description of reality."
The quote by Dale T. Mortensen suggests that the concept of "market clearing," where all goods and services are sold at their equilibrium price, is more of an abstract theory than an accurate reflection of real-world markets. In actuality, markets often experience disequilibrium due to factors such as information asymmetry, market frictions, and irrational behavior, which prevent immediate adjustments in supply and demand to reach the ideal equilibrium point. This insight underscores the need for economic models to account for these complexities and imperfections when studying and predicting real-world market behavior.
"Job vacancies and job openings are not the same thing." (This quote is frequently misattributed to Dale T. Mortensen, but it's actually from his co-author Christopher A. Pissarides)
This quote emphasizes that while a job vacancy refers to an unfilled position in a company or organization, a job opening is a broader term that includes all positions for which the employer is currently accepting applications, regardless of whether they are actively being filled or not. In other words, a job opening may exist even if there is no one officially designated as the vacant position's holder, and a job vacancy may persist for some time before it becomes an open position. This distinction is crucial in understanding the labor market dynamics, especially when discussing employment trends and policies.
I became a member of the faculty at Northwestern University in 1965 but did not complete my thesis until two years later at a graduate ceremony at which Carnegie Institute of Technology became Carnegie-Mellon University. At Northwestern, I was mentored by the 'three Bobs:' Robert Eisner, Robert Strotz and Robert Clower.

Over the years, the technology of trade has changed in response to advances in the ability to communicate. From its origins on the streets of Chicago, the Board of Trade moved to a building housing 'trading pits' for the open-outcry exchange by brokers representing buyers and sellers.

As the future is never known with certainty, the evaluation of the prospective benefits requires the formation of expectations. An acceptable house, partner or job, then, is one that offers an expected stream of future benefit that has a value in excess of the option to continue to search for an even better alternative.
