We examine the long-term labor market impact of the steam engine, an early general-purpose technology, by linking newly digitized 19th-century records from Prussia to modern German labor market data (1975-2019). Regions with a higher concentration of steam engines per worker in 1875 exhibit...

Combined cycle (CC) plants are expected to play an important role in balancing generation of heat and electricity from non-dispatchable renewable energy sources. In this work, we study different retrofit options for using hydrogen in CC plants to reduce the plant's CO2 emissions. These options...

Empirical evidence on the historical role of Compulsory Schooling Laws (CSL) for the spread of mass education is mixed at best. This is also due to the difficulty of identifying exogenous variation in the application of CSL. We exploit an almost unique feature of a CSL in 1877 Italy which was...

We describe our digitization of a uniquely detailed study of 19 th century production methods assembled by the United States Department of Labor (1899). The staff spent five years collecting and assembling data on the production of hundreds of highly specific products (as well as some services)...

The solidification characteristics of C700R-1 alloy was investigated by DSC analysis, in-situ observation, quenching experiment and Thermo-Calc calculation. The segregation behavior during solidification was analyzed by Scanning Electron Microscope and Electron Probe Microanalysis. At the...
