Kaldor's stylized facts of economic growth International Trade & the World Economy; Charles van Marrewijk Nicholas Kaldor (1961) suggested the following list of stylized facts: The continued growth in the aggregate volume of production and in the productivity of labor at a steady trend rate. A continued increase in the amount of capital per worker. A steady rate of profit on capital. Steady capital-output ratios over long periods. A steady investment coefficient, and a steady share of profits and wages.

Endogenous growth International Trade & the World Economy; Charles van Marrewijk Paul Romers (1994) list of stylized facts: There are many firms in a market economy. Discoveries differ from other inputs in that many people can use them at the same time (nonrival goods). It is possible to replicate physical activities. Technological advance comes from things that people do. Many individuals and firms have market power and earn monopoly rents on discoveries.

Endogenous growth International Trade & the World Economy; Charles van Marrewijk Production function: Operating profit for manufactures producer Future profits discounted; profits erode if number of varieties increases Inventing new variety represents fixed cost; with knowledge spillovers economy steadily grows forever; growth rate higher if: the labor force is higher (increasing returns to scale ensure that size is important) the fixed costs of investment F are lower, and the discount rate is lower.

Conclusions International Trade & the World Economy; Charles van Marrewijk Rising per capita income is relatively new phenomenon. Some countries have experienced relatively steady growth, others long periods of stagnation and rapid increases. Neo-classical model based on capital accumulation needs exogenous technological change to explain growth; large Solow residual. Endogenous growth models based on imperfect competition and innovation (new goods and/or quality improvements) led by entrepreneurs in search of profits. Large swings in economic prosperity may be explained by geographical economics model.
