Natural Experiments in Macroeconomics
A growing literature relies on natural experiments to establish causal effects in macroeconomics. In diverse applications, natural experiments have been used to verify underlying assumptions of conventional models, quantify specific model parameters, and identify mechanisms that have major effects on macroeconomic quantities but are absent from conventional models. We discuss and compare the us...
متن کاملLandscape evolution models
Geomorphology is the study of Earth’s landforms and the processes that shape them. From its beginnings, geomorphology has embraced a historical approach to understanding landforms; the concept of evolving landforms is firmly ingrained in geomorphic thought. Modern process geomorphologists use the term landscape evolution to describe the interactions between form and process that are played out ...
متن کاملThe Evolution of Landscape
Earth’s landscape is continually evolving as land uplifted by tectonic and volcanic processes is eroded by water, ice, and wind. On Earth, the dominant landforms have been produced by the action of rivers and glaciers transporting material from mountains to the sea. The amount and proportion of water and ice available for changing the landscape are both sensitive to climatic regime, so that a s...
متن کاملExperiments in Linear Natural Deduction
We investigate several fragments of multiplicative linear logic, in a natural deduction setting and with the aim of a better understanding of the par connective. We study, first, a pre-tensorial calculus, which is strengthened then in the standard tensorial fragment. The addition of a further pre-tensorial connective yields (a natural deduction version of) Full Intuitionistic Linear Logic. A fu...
متن کاملSelf-organized criticality in forest-landscape evolution
A simple cellular automaton replicates the fractal pattern of a natural forest landscape and predicts its evolution. Spatial distributions and temporal fluctuations in global quantities show power-law spectra, implying scale-invariance, characteristic of self-organized criticality. The evolution toward the SOC state and the robustness of that state to perturbations are described. 2002 Elsevie...
