The father of the economic interpretation of the new imperialism was the British liberal economist John Atkinson Hobson. In his seminal study, Imperialism, a Study (first published in 1902), he pointed to the role of such drives as patriotism, philanthropy, and the spirit of adventure in advancing the imperialist cause. As he saw it, however, the critical question was why the energy of these active agents takes the particular form of imperialist expansion. Hobson located the answer in the financial interests of the capitalist class as “the governor of the imperial engine.” Imperialist policy had to be considered irrational if viewed from the vantage point of the nation as a whole: the economic benefits derived were far less than the costs of wars and armaments; and needed social reforms were shunted aside in the excitement of imperial adventure. But it was rational, indeed, in the eyes of the minority of financial interest groups. The reason for this, in Hobson’s view, was the persistent congestion of capital in manufacturing. The pressure of capital needing investment outlets arose in part from a maldistribution of income: low mass consuming power blocks the absorption of goods and capital inside the country. Moreover, the practices of the larger firms, especially those operating in trusts and combines, foster restrictions on output, thus avoiding the risks and waste of overproduction. Because of this, the large firms are faced with limited opportunities to invest in expanding domestic production. The result of both the maldistribution of income and monopolistic behaviour is a need to open up new markets and new investment opportunities in foreign countries.

Hobson’s study covered a broader spectrum than the analysis of what he called its economic taproot. It also examined the associated features of the new imperialism, such as political changes, racial attitudes, and nationalism. The book as a whole made a strong impression on, and greatly influenced, Marxist thinkers who were becoming more involved with the struggle against imperialism. The most influential of the Marxist studies was a small book published by Lenin in 1917, Imperialism, the Highest Stage of Capitalism. Despite many similarities, at bottom there is a wide gulf between Hobson’s and Lenin’s frameworks of analysis and also between their respective conclusions. While Hobson saw the new imperialism serving the interests of certain capitalist groups, he believed that imperialism could be eliminated by social reforms while maintaining the capitalist system. This would require restricting the profits of those classes whose interests were closely tied to imperialism and attaining a more equitable distribution of income so that consumers would be able to buy up a nation’s production. Lenin, on the other hand, saw imperialism as being so closely integrated with the structure and normal functioning of an advanced capitalism that he believed that only the revolutionary overthrow of capitalism, with the substitution of Socialism, would rid the world of imperialism.

Lenin placed the issues of imperialism in a context broader than the interests of a special sector of the capitalist class. According to Lenin, capitalism itself changed in the late 19th century; moreover, because this happened at pretty much the same time in several leading capitalist nations, it explains why the new phase of capitalist development came when it did. This new phase, Lenin believed, involves political and social as well as economic changes; but its economic essence is the replacement of competitive capitalism by monopoly capitalism, a more advanced stage in which finance capital, an alliance between large industrial and banking firms, dominates the economic and political life of society. Competition continues, but among a relatively small number of giants who are able to control large sectors of the national and international economy. It is this monopoly capitalism and the resulting rivalry generated among monopoly capitalist nations that foster imperialism; in turn, the processes of imperialism stimulate the further development of monopoly capital and its influence over the whole society.

The difference between Lenin’s more complex paradigm and Hobson’s shows up clearly in the treatment of capital export. Like Hobson, Lenin maintained that the increasing importance of capital exports is a key figure of imperialism, but he attributed the phenomenon to much more than pressure from an overabundance of capital. He also saw the acceleration of capital migration arising from the desire to obtain exclusive control over raw material sources and to get a tighter grip on foreign markets. He thus shifted the emphasis from the general problem of surplus capital, inherent in capitalism in all its stages, to the imperatives of control over raw materials and markets in the monopoly stage. With this perspective, Lenin also broadened the concept of imperialism. Because the thrust is to divide the world among monopoly interest groups, the ensuing rivalry extends to a struggle over markets in the leading capitalist nations as well as in the less advanced capitalist and colonial countries. This rivalry is intensified because of the uneven development of different capitalist nations: the latecomers aggressively seek a share of the markets and colonies controlled by those who got there first, who naturally resist such a redivision. Other forces—political, military, and ideological—are at play in shaping the contours of imperialist policy, but Lenin insisted that these influences germinate in the seedbed of monopoly capitalism.

Noneconomic imperialism

Perhaps the most systematic alternative theory of imperialism was proposed by Joseph Alois Schumpeter, one of the best known economists of the first half of the 20th century. His essay “Zur Soziologie des Imperialismus” (“The Sociology of Imperialism”) was first published in Germany in the form of two articles in 1919. Although Schumpeter was probably not familiar with Lenin’s Imperialism at the time he wrote his essay, his arguments were directed against the Marxist currents of thought of the early 20th century and in particular against the idea that imperialism grows naturally out of capitalism. Unlike other critics, however, Schumpeter accepted some of the components of the Marxist thesis, and to a certain extent he followed the Marxist tradition of looking for the influence of class forces and class interests as major levers of social change. In doing so, he in effect used the weapons of Marxist thought to rebut the essence of Marxist theory.

A survey of empires, beginning with the earliest days of written history, led Schumpeter to conclude that there are three generic characteristics of imperialism: (1) At root is a persistent tendency to war and conquest, often producing nonrational expansions that have no sound utilitarian aim. (2) These urges are not innate in man. They evolved from critical experiences when peoples and classes were molded into warriors to avoid extinction; the warrior mentality and the interests of warrior classes live on, however, and influence events even after the vital need for wars and conquests disappears. (3) The drift to war and conquest is sustained and conditioned by the domestic interests of ruling classes, often under the leadership of those individuals who have most to gain economically and socially from war. But for these factors, Schumpeter believed, imperialism would have been swept away into the dustbin of history as capitalist society ripened; for capitalism in its purest form is antithetical to imperialism: it thrives best with peace and free trade. Yet despite the innate peaceful nature of capitalism, interest groups do emerge that benefit from aggressive foreign conquests. Under monopoly capitalism the fusion of big banks and cartels creates a powerful and influential social group that pressures for exclusive control in colonies and protectorates, for the sake of higher profits.

Notwithstanding the resemblance between Schumpeter’s discussion of monopoly and that of Lenin and other Marxists, a crucial difference does remain. Monopoly capitalism in Lenin’s frame of reference is a natural outgrowth of the previous stage of competitive capitalism. But according to Schumpeter, it is an artificial graft on the more natural competitive capitalism, made possible by the catalytic effect of the residue from the preceding feudal society. Schumpeter argued that monopoly capitalism can only grow and prosper under the protection of high tariff walls; without that shield there would be large-scale industry but no cartels or other monopolistic arrangements. Because tariff walls are erected by political decisions, it is the state and not a natural economic process that promotes monopoly. Therefore, it is in the nature of the state—and especially those features that blend the heritage of the previous autocratic state, the old war machine, and feudal interests and ideas along with capitalist interests—that the cause of imperialism will be discovered. The particular form of imperialism in modern times is affected by capitalism, and capitalism itself is modified by the imperialist experience. In Schumpeter’s analysis, however, imperialism is not an inevitable product of capitalism.
