The standard Le Chatelier Principle states that the long-run demand for a good (in which by definition there are fewer restraints on the variables) is more elastic than short-run demand. The fundamental insight above goes well beyond demand theory, and proofs of this basic idea have been found...

We study properties of the solutions to a parametrized constrained optimization problem in Hilbert spaces. A special operator is studied which is of importance in economic theory; sufficient conditions are given for its existence, symmetry, and negative semidefiniteness. The techniques used are...

Let M and N be the set of minimizers of a function f over respective subsets K and L of a lattice, with K being lower than L. This paper characterizes the class of functions f for which M is lower (resp., weakly lower, meet lower, join lower, chain lower) than N for all K lower than L. The...

The complete system of ordinary differential equations developed by Kalaba and Tesfatsion (1981) for tracking solution branches of parameterized nonlinear systems is tested using several illustrative examples. One example is the standard Ramsey optimal growth model, for which analytical...

How would the tariff rate in a political economy respond to changes in exogenous environment? To answer this question a bargain-theoretic approach is adopted and a tariff-endogenous general equilibrium model of a small open political economy is derived. A comparative static analysis of the model...

We establish four necessary and sufficient conditions for the existence of the Averch-Johnson effect in a generalized version of their famous model of the rate-of-return regulated firm. The four necessary and sufficient conditions are then compared to the two stronger sufficient conditions for...

Within a production theoretic framework, this paper considers an axiomatic approach to benchmark selection. It is shown that two simple and weak axioms: efficiency and comprehensive monotonicity characterize a natural family of benchmarks which typically becomes unique. Further axioms are added...

The innovation of modeling firm search behavior using NK fitness landscapes is twenty years old, but despite the potential of this method its adoption remains sparse. This is likely be due to three reasons. First, many questions of current interest are not amenable to the classic NK model...

Additive manufacturing (AM) was initially designed for prototyping and product personalization, where high production quantities were not required. Now, it is also implemented for final part production to achieve cost-effective mass customization (MC). Thanks to its tool-less production and...
