In 1903 Alfred Marshal, the first Professor of Political Economy at Cambridge University, established what was to become the Economics Tripos as an undergraduate degree course at the Faculty of Economics and Politics. Economics in the Rear-view Mirror is on the lookout for these examinations. The 1924 Economics Tripos is the seventh transcribed and posted thus far.

INDUSTRY AND LABOUR.
MONDAY, June 2, 1924. 1.30—4.30.
- What influences govern the introduction of labour-saving machinery into industry? Why is it more used in some countries than in others?
- “The only trades which is seems possible for a joint stock company to carry on successfully, without an exclusive privilege, are those of which all the operations are capable of being reduced to what is called a routine….Of this kind is, first, the banking trade; secondly, the trade of insurance…; thirdly, the trade of making or maintaining a navigable cut or canal; and fourthly, the similar trade of bringing water for the supply of a great city.” (ADAM SMITH.)
Joint Stock Companies appear to operate successfully in many spheres to-day. How do you account for this development? - What do you understand by the phrase “economy of high wages”? How can it be economical for an employer to pay high wages?
- “The notion we can secure real stability in enterprise and freedom from unemployment, even if the stabilization of the general price level were entirely successful, might bring with it grave disappointment.” (HARTLEY WITHERS.)
Examine this contention. - Discuss the various methods, in use in this country, of preventing or settling industrial disputes.
- Compare and classify the different types of industrial combinations.
- Examine these suggestions.
-
- “Wages should vary with movements in the price of the commodity which the wage-earner helps to produce.”
- “Wages should vary with movements in the Ministry of Labour cost of living figures.”
- “Wages should vary with movements in the general level of prices.”
-
- Discuss the argument that such schemes as profit-sharing, co-partnership, etc., are socially undesirable because they reintroduce into the workers’ lives an element of fluctuating uncertainty from which the ordinary wage system relieves them.
- Distinguish between “craft unionism” and “industrial unionism” and show the importance of this distinction in modern Trade Union development.
- Is it true that a margin of unemployed labour is essential to the satisfactory working of the present system of economic organization? State reasons for your answer.

State the case for agricultural co-operation in this country.

TUESDAY, June 3, 1924. 9—12.
- “Cheap capital and cheap labour are essential conditions of a rapid growth of national wealth.” Comment.
- “The law of diminishing returns, emphasizing as it does the tendency of land to deteriorate under use, resembles the allowances that industrialists make for the annual depreciation of machinery.” Consider whether the suggested analogy is justified.
- Is there loss of national wealth if an invention appears which suddenly renders obsolete great masses of expensive machinery?
- What are the chief qualifications to be made to the assumption that it is desirable that all new capital should be free to flow into the channels most profitable to the owner of the capital?
