In this article free vibration of a Timoshenko nanobeam with variable cross-section is investigated using nonlocal elasticity theory within the scope of continuum mechanics. Small scale effects are modelled after Eringen’s nonlocal elasticity theory while the non-uniformity is presented by exponentially varying width through the beam length with constant thickness. Analytical solution is achiev...

[Abstract] An increasing returns model with trade cost predicts that firms are located in a larger economy. We recognize that this theory will be more appropriately applied in a context of local regional economy than a nation as a whole. However, as we move on to focus on local regions within a country, we expect to observe ‘epicenter’ (agglomeration) force for domestic market and ‘periphery’ (...

We consider a discrete-time two-sector CES economy with sector specific external effects and partial depreciation of capital. We show that the occurrence of local indeterminacy of equilibria depends on an interplay between factor substitutability and capital depreciation. When the elasticity of substitution is less than one, local indeterminacy may occur with low depreciation of capital. When t...
