Empirical Evidence for Decreasing Returns to Scale in a Health Capital Model [PDF]

SSRN Electronic Journal, 2012
We estimate a health investment equation, derived from a health capital model that is an extension of the well-known Grossman model. Of particular interest is whether the health production function has constant returns to scale, as in the standard Grossman model, or decreasing returns to scale, as in the Ehrlich-Chuma model and extensions thereof.

Multiscale unified prediction of size/scale and Hall-Petch effects in the mechanics of polycrystalline materials

Journal of the Mechanical Behavior of Materials, 2013
Materials show size effects in their strength, i.e., improved strength as size decreases. Size effects have been studied extensively at a wide range of scales, from atomistic to continuum.

Decreased attention to object size information in scale errors performers [PDF]

Infant Behavior and Development, 2017
Young children sometimes make serious attempts to perform impossible actions on miniature objects as if they were full-size objects. The existing explanations of these curious action errors assume (but never explicitly tested) children's decreased attention to object size information.

Brief communication Decreasing fires in a Mediterranean region (1970–2010, NE Spain) [PDF]

Natural Hazards and Earth System Sciences, 2013
We analyse the recent evolution of fires in Catalonia (north-eastern Iberian Peninsula), a typical Mediterranean region. We examine a homogeneous series of forest fires in the period 1970–2010.

IS THERE EMPIRICAL EVIDENCE FOR DECREASING RETURNS TO SCALE IN A HEALTH CAPITAL MODEL? [PDF]

Health Economics, 2012
ABSTRACTWe estimate a health investment equation, derived from a health capital model that is an extension of the well‐known Grossman model. Of particular interest is whether the health production function has constant returns to scale, as in the standard Grossman model, or decreasing returns to scale, as in the Ehrlich–Chuma model and extensions ...

Biotic homogenization can decrease landscape-scale forest multifunctionality [PDF]

Proceedings of the National Academy of Sciences, 2016
Significance Numerous studies have demonstrated the importance of biodiversity in maintaining multiple ecosystem functions and services (multifunctionality) at local spatial scales, but it is unknown whether similar relationships are found at larger spatial scales in real-world landscapes.
