This paper works out some of the basic properties of an economy with energy as a factor of production. The economy now consists of streams of energy conversions that direct energy to the production of goods and services. The focus on energy generates a variety of insights. It yields a new...

Economic growth in the 19th and 20th centuries, following the Industrial Revolutions, was much faster than in preceding centuries. This unprecedented global growth coincided with the global proliferation of democracy, with some evidence for bidirectional causation. Macroeconomic forecasts have...

20 years after unification, the East German twin's economic position is relatively stagnant compared to most of the West German productivity and income variables. The strong initial takeoff until the mid-end 1990s ended at a level of 70% to 80% of the western reference. In this paper, two...

The twentieth century was a period of outstanding economic growth together with an unequal income distribution. This paper analyses the international distribution of growth rates and its dynamics during the twentieth century. We show that the whole century is characterized by a high...

This paper explores the implications of Unified Growth Theory for the origins of existing differences in income per capita across countries. The theory sheds light on three fundamental layers of comparative development. It identifies the factors that have governed the pace of the transition from...

Prior to the early part of the 19th century, China’s economy had long been superior to that of the West’s. The Chinese’s ability to utilize science and technology had been instrumental in leading their enormous population to economic prosperity and for a while, superiority. During the 18th...

This paper is a theoretical and empirical exploration of the connections between sovereignty (or its absence) and growth rates in lagging countries over the period 1870 to 1950. Using a four-fold taxonomy of sovereignty, our estimates of sovereignty differentials for growth rates of per capita...

Long-run economic growth has again become a major focus of economic theory. A perception of technological change as an economic process with externalities has motivated the development of aggregate models that generate different steady-state growth paths. Economic history has also long been...

The Second World War II (WWII) was arguably one of the largest shocks to the U.S. economic and production system in history. Historians, business historians, and economists have largely discussed the stimulus that WWII had on U.S. technological advancements. However, its effect on U.S....

Although cross section relationships are often taken to indicate causation, and especially the important impact of economic growth on many social phenomena, they may, in fact, merely reflect historical experience, that is, similar leader-follower country patterns for variables that are causally...
