The construction industry claims a vast quantity of natural resources and is responsible for more than half of the waste generated in Germany. R-concrete contains recycled aggregates and is a resource efficient alternative to primary concrete. A central stakeholder whose preferences may...

Concrete with recycled aggregates ("R-concrete") offers a way to reduce the extraction of natural resources and to close material loops in line with political goals. However, market failures may hamper the efficient use of R-concrete in construction. Various policy instruments can be used in...

Many studies have documented large and persistent productivity differences across producers, even within narrowly defined industries. This paper both extends and departs from the past literature, which focused on technological explanations for these differences, by proposing that demand-side...

This Final Report describes the technical activities carried out under this RFCS contract RFSR CT 2012-00030 which is concerned with developing new rules for the partial shear connection of composite beams. Based on a comprehensive series of push tests on deck profiles of 56 to 80 mm height with...

This paper presents a quantitative model of productivity dispersion to explain why inefficient producers are slowly selected out of the ready-mix concrete industry. Measured productivity dispersion between the 10th and 90th percentile falls from a 4 to 1 difference using OLS, to a 2 to 1...

Fluctuations in demand cause some plants to exit a market and other to enter.Would eliminating these fluctuations reduce plant turnover? A structural model of entry and exit in concentrated markets is estimatedfor the ready-mix concrete industry, using plant level data from the U.S. Census. The...

In markets where spatial competition is important, many models predict that average prices are lower in denser markets (i.e., those with more producers per unit area). Homogeneous-producer models attribute this effect solely to lower optimal markups. However, when producers instead differ in...
