Moses Abramovitz (January 1, 1912 – December 1, 2000) was a 20th-century Americaneconomist andprofessor. During his career, he made many contributions to the study of macroeconomic fluctuations and economic growth over time.^[1]

Born and raised in aJewish family inBrooklyn,New York, he completed hisbachelor's degree ineconomics summa cum laude atHarvard University. He went to Harvard with the intention of becoming alawyer and studiedcriminal justice as well as economics. However, he became more interested in economics because he was able to connect it to the world in which he was living. He earned hisPh.D. atColumbia University in 1939.^[2] In 1985, he was awarded anhonorary doctorate from the Faculty of Social Sciences atUppsala University,Sweden.^[3] In 1992, he was invited toRome to become a fellow of the prestigiousAccademia Nazionale Dei Lincei. He was awarded another doctorate from theUniversity of Ancona in 1992. Abramovitz died atStanford Hospital inCalifornia on December 1, 2000, at the age of 88, after contracting a gastrointestinalinfection.

Abramovitz, called Moe by family and friends, was known for his modest personality and was described as one of the least ego-driven scholars in economics. He married Carrie Glasser, a Brooklyn-born painter and sculptor, in 1937. She died in 1999.^[4]

Abramovitz started his career as a lecturer at Harvard in the mid-1930s. After finishing his doctorate at Columbia, he joined theNational Bureau of Economic Research in New York, where he began his investigation of inventory investment cycles. DuringWorld War II, Abramovitz served on theWar Production Board and in theOffice of Strategic Services as chief of the European industry and trade section. In 1945 and 1946, he was an economic adviser to the United States representative on the Allied Reparations Commission.^[5] He was also a founding faculty member of the Department of Economics atStanford University, which he joined in the fall of 1948. He taught there for almost 30 years.^[6] From 1962 to 1963, he was the adviser to the secretary general of theOrganization for Economic Cooperation and Development inParis. He then served as the organization chair from 1963 to 1965 and from 1971 to 1974. Over the course of his career, Abramovitz carried out many pioneering studies ofmacroeconomics and long-termgrowth. His 1986 article, "Catching Up, Forging Ahead and Falling Behind" is the second most cited of all the papers published by theJournal of Economic History.^[7]

He referred tototal factor productivity as a "measure of our ignorance about the causes of economic growth".

This result is surprising in the lopsided importance which it appears to give to productivity increase, and it should be, in a sense, sobering, if not discouraging, to students of economic growth. Since we know little about the causes of productivity increase, the indicated importance of this element may be taken to be some sort of measure of our ignorance about the causes of economic growth in the United States and some sort of indication of where we need to concentrate our attention.

Abramovitz's catch-up growth hypothesis attempted to explainWestern Europe's Golden Era ofeconomic growth from 1948 to 1972. He essentially concluded that the key to the growth was Western Europe's ability to import and implement technology from the United States. The growth rate of a developing country will be higher than the growth rate of a developed country because thediminishing return of developing countries is much lower. If a country is trying to be industrialized, it can only be better off; it will grow much faster than countries that are already industrialized. In the process, the country creates more jobs and more capital, which means the economy's total revenue will increase more and more quickly.^[8]

Abramovitz's theory does not guarantee that poor countries will catch up to developed countries, because the poor countries might fail to adapt to new technology, attract capital and participate in the global market.

If a country cannot adapt to the technology it is offered, it will not be able to generate more capital, which will cause the catch-up process to fail. If the country does not build relationships with developed nations, the process will also fail. Building such relationships is so important because it is developed countries that will purchase most of developing countries' capital. If the developing country sells more capital, it will grow. If it grows, it will catch up.^[9]

During his time at the National Bureau of Economics Research, Abramovitz researched the roleinventories play in business cycles. A business cycle is a fluctuation in economic activity over a period of time. The fluctuation may be good, as with a boom and economic expansion, or bad, as with arecession ordepression. In his paper "The Role of Inventories in Business Cycles," Abramovitz wrote that inventory can play a negative role if there is a lag in the production of the inventory. A lag can occur for the following reasons:

1. Many goods need to be produced to create one whole product. For example, to manufacture a car, several kinds of goods are required. If there is a lag in obtaining any of those goods, it slows down the production of the car. This prevents the market from meetingdemand, which leads to less revenue.
2. Raw materials purchased from domestic manufacturers or dealers may lag by a few months. For example, to make fabric, many types of raw material—such ascotton,nylon,wool, andpolyester—are required. If domestic manufacturers or dealers are unable to produce the raw material on time, the market will suffer because it cannot meet demand.
3. Raw materials purchased from distant sources or on long-term contracts may also arrive late. When domestic manufacturers and dealers cannot produce enough, a nation has to reach out to other nations, which takes much longer. This can also cause the market to lack products consumers want.
4. Finished goods made to order are closely tied to output. Even if raw materials are received on time and goods are produced on time, the inventory may not be enough to meet demand. Producing more requires starting from scratch. Meanwhile, the market does not have any goods to sell.^[10]

Aggregate inventories of wholesalers and retailers also appear to have lagged behind sales by about six months. Detailed studies reveal that this lag reflects large differences in the ability of merchants in different trades to keep the rate at which they receive goods in line with the rate at which they can dispose of them. Some merchants' ability to adjust inventories to sales is so limited as to produce a long lag of stocks behind sales, or even an inverse relationship between sales and inventories. If these various lags are worked out, a country can stop the negative effect of inventories on the national market.
