Owning a business does not, for Schumpeter, make someone an entrepreneur; nor does managing it efficiently. In this 1928 encyclopedia article, he locates entrepreneurship in the practical implementation of new economic possibilities—redirecting resources while overcoming habit, uncertainty, and resistance from creditors, workers, or customers. His distinction makes room for salaried directors and promoters as well as owner-managers, separating entrepreneurial leadership from property, invention, and routine administration. Readers can discover why profit seeking alone cannot explain this activity, and why its institutional setting matters. The article’s closing tension sharpens the account: as innovation becomes customary and specialist expertise makes decisions more calculable, economic development may diminish the need for the exceptional personal leadership that helped set it in motion.

A leading sugar manufacturer who opposed the sugar cartel: this tension gives Schumpeter’s brief encyclopedia portrait of Rudolf Auspitz its political interest. His theoretical assessment turns on a different distinction—between early neglect and genuine originality. Schumpeter credits the price theory Auspitz developed with Richard Lieben with pioneering geometrical methods and a symmetry between cost and utility, insisting that its appearance before Marshall’s Principles matters to any judgement of its contribution. The entry offers a compact encounter with Schumpeter as a historian of economics, weighing an industrialist’s liberal convictions alongside mathematical ideas he considered still only partly exploited.

To call Böhm-Bawerk a theorist of interest is, in Schumpeter’s judgement, to understate his project. This brief 1930 encyclopedia entry places interest within a wider account of production and distribution, organized around time: the relation between consumption goods already available and those expected from production processes of different lengths. Schumpeter pairs this interpretation with a portrait of the Austrian finance minister, praising his budgetary discipline and legislative achievements despite difficult political circumstances and no personal party affiliation. The result is a compact assessment of both administrator and economist, especially useful for understanding why Schumpeter regarded Böhm-Bawerk’s explanation of interest as one result of a larger analysis rather than its sole purpose.

What makes an observed fluctuation a business cycle rather than a movement caused by war, growth, or industrial innovation? In this 1930 review of Wesley C. Mitchell’s Business Cycles: The Problem and Its Setting, Joseph A. Schumpeter turns admiration for empirical research into a pointed argument about its analytical foundations. Statistics and business annals, he contends, cannot identify their own objects: cycle durations, price indices, and fitted trends acquire economic meaning only through explicit theoretical distinctions. His disagreement with Mitchell is not a rejection of observation but a demand for reciprocal work between measurement and theory. The review offers a concrete way to examine how apparently neutral decisions about counting, averaging, and classification shape what economists can explain.

Such difference in outlook as remains between us can be summarized by saying the theory of the cycle is not the last but the first step on the road to our goal.

Why did a recurrent economic downturn become a world depression? Writing in March 1931, Schumpeter separates the adjustments generated by productive innovation from the pressures that made this contraction exceptionally severe. His distinctive claim is that prosperity itself transforms production in ways that require recession; external shocks cannot alone explain the reversal. Yet overlapping cycles do not account for the catastrophe. Monetary restoration, reparations, agricultural distress and price rigidities enter his diagnosis as aggravating forces, not interchangeable root causes. This short article offers a pointed way to distinguish the origins of a crisis from its amplification—and to understand why, in Schumpeter’s view, cheaper credit may fail to revive borrowing even when high interest rates can readily restrain a boom.

It is easier to dampen prosperity by a high rate of interest than to alleviate depression by a low one.

Why should an economy’s growing productive power bring bankruptcies and unemployment rather than uninterrupted prosperity? In this 1931 article, based on his Tokyo lecture, Joseph A. Schumpeter locates the answer in the boom itself. Pioneering innovations attract imitators; bank-created credit finances a rush of new enterprises before their goods reach the market. When those goods arrive, they displace older producers, while repayment of loans contracts purchasing power. Depression, in his account, is the painful adjustment to changes initiated during prosperity, not simply a monetary malfunction. The article offers a compact route into Schumpeter’s distinctive connection between entrepreneurial achievement and economic instability, while distinguishing the mechanism he seeks to explain from external shocks and statistical patterns that cannot, by themselves, establish causes.

France and Germany had much to gain from economic cooperation during the Depression—but why should mutual advantage produce political agreement? In this 1932 article, Schumpeter separates the economic case for reconciliation from the national passions and parliamentary constraints obstructing it. Reparations sharpen the contradiction: Germany must export to pay, while its creditors resist German goods. Yet he also questions remedies that look cooperative, from producer agreements benefiting monopolists at consumers’ expense to foreign credit that postpones necessary adjustment. His distinctive contribution is to show how apparently threatening German exports reflect debt obligations rather than simply industrial strength. The reader encounters a case for commercial accommodation that refuses to mistake economic compatibility for political confidence, or capital flows for a means of creating it.

There is in politics a large irrational element even in economic matters.

Can a theory of prices explain whether people become better off? In this 1932 review of the first two volumes of G.-H. Bousquet’s Institutes de Science économique, Schumpeter treats that question as a test of economic theory’s reach. He admires Bousquet’s accessible presentation of Walras and Pareto, yet distinguishes equilibrium’s analytical power from its less secure application to the wider social environment. His sharpest discussion concerns Bousquet’s return to subjective satisfaction—and the claim that habit and new wants eventually cancel the felt benefits of economic improvement. Schumpeter praises the ingenuity of this argument without simply accepting its conclusion. The review offers a compact encounter with his critical standards: theoretical clarity matters, but so does recognizing the questions a successful method leaves unanswered.

A gifted biographer can restore an economist’s reputation—and distort the distribution of intellectual credit. In this 1933 review of Keynes’s Essays in Biography, Schumpeter admires the intimacy and literary skill of the portraits while questioning the judgments they sustain. Keynes’s rehabilitation of Malthus, he argues, risks projecting contemporary objections to saving onto different historical conditions; his compelling account of Marshall leaves Edgeworth’s theoretical achievements comparatively obscure. Schumpeter writes as a fellow economist alert both to analytical invention and to the means by which it becomes memorable. The review offers a compact encounter between two ways of judging economic achievement, showing how personal allegiance, present concerns, and narrative power can shape the history of a discipline.

Mathematical theory can describe quantitative relationships without determining their numerical values. For Schumpeter, closing that gap is the distinctive task of econometrics. In this 1933 article, he explains why prices are inherently numerical and why economists nevertheless struggle to bring theory, statistical methods, and observed facts into a single argument. His diagnosis is as much institutional as technical: theorists, statisticians, and collectors of evidence work apart, without sufficient shared training or exchange. Rather than demand a common doctrine, he proposes cooperation on concrete problems. The article offers a conception of numerical research as a discipline that can reshape theory—not simply confirm it or deliver immediate policy answers—while explicitly preserving a place for nonquantitative inquiry.

The individual problems themselves are, as it were, to teach us how they want to be handled.

How can economists learn modern statistical methods when their mathematical preparation falls short? In this 1933 review of Wilhelm Winkler’s Grundriß der Statistik, I. Theoretische Statistik, Joseph A. Schumpeter assesses the compromises an intermediate textbook must make. He values worked examples as a means of independent study where university teaching is inadequate, but does not confuse accessibility with full understanding. His sharpest pedagogical objection concerns the placement of abstract foundations: what comes first logically may become intelligible only after practical work. The review offers a concrete view of Schumpeter’s standards for economic training—statistics alongside theory and economic history—and of his distinction between methods every economist should command and foundational controversies that an introductory course need not resolve.

Was the Depression an exceptional disruption, or did ordinary business cycles continue beneath it? In this brief, author-prepared summary, Schumpeter distinguishes the downturn’s cyclical shape from its catastrophic severity. He proposes three overlapping cycles rather than a single wave, interpreting the descent to August 1932 and the ensuing recovery through their coinciding depressive phases. Yet he assigns the catastrophe’s intensity to outside disturbances, including what he regards as mistaken efforts to stabilize “prosperity plateaus.” The distinctive interest is this boundary between cyclical explanation and policy judgement: Schumpeter sketches how theory, historical evidence, and statistics might identify an underlying movement without claiming that it alone explains the disaster.
