The Demographic Foundations of Change in U.S. Households in the Twentieth Century

This article explains the level of economic freedom in Muslim countries through the theory of institutional path dependency. Islamic countries are generally not free and they have a poor record regarding property rights. To explain these realities we use the institutional history of Muslim countries. We define three steps: the Arab and Ottoman Empires when Islamic law was of great importance, E...

Hugo de Vries's mutation theory is now little more than a footnote to the history of biology, a failed theory that briefly led a few biologists astray. However, for the first quarter of the twentieth century it attracted considerable attention from both professional biologists and laypeople. De Vries's theory--together with the plant, Oenothera lamarckiana, that had supplied most of his evidenc...

The expected decline of health indicators with economic recessions and improvement with economic growth in the nineteenth century Sweden was reversed in the twentieth century, giving the counterintuitive pattern of higher mortality and lower life expectancy in economic expansions and improvement of these indices in recessions. The change or "tipping point" occurred at the end of the nineteenth ...

In the late twentieth century, the sub-thermocline waters of the southern tropical and subtropical Indian Ocean experienced a sharp cooling. This cooling has been previously attributed to an anthropogenic aerosol-induced strengthening of the global ocean conveyor, which transfers heat from the subtropical gyre latitudes toward the North Atlantic. From the mid-1990s the sub-thermocline southern ...

Darwin believed that his theory of evolution would stand or fall on its ability to account for human behavior. No species could be an exception to his theory without imperiling the whole edifice. The ideas in the Descent of Man were widely discussed by his contemporaries although they were far from being the only evolutionary theories current in the late nineteenth century. Darwin's specific ev...

The purpose of this paper is to identify the changes in the impact of energy shocks on economic activity at different phases of economic development – with an interest in assessing if the economy’s vulnerability and resilience to shocks improved. Using data on the United Kingdom over the last three hundred years, the paper replicates a method introduced by Kilian (2008) to disentangle supply, d...
