We explore the impact of reciprocal, specific or ad valorem, import tariffs on welfare among N symmetric countries (a free-trade agreement)—using the standard Krugman’s one-sector trade model, with unspecified variable-elasticity preferences (mostly under decreasing elasticity of utility)....

Using a novel source of quasi-experimental variation in interest rates, we develop a new approach to estimating the Elasticity of Intertemporal Substitution (EIS). In the UK, the mortgage interest rate features discrete jumps – notches – at thresholds for the loan-to-value (LTV) ratio. These...

The main aim of this paper is to prove the existence of a new production function with variable elasticity of factor substitution. The econometric estimates presented in the paper confirm some other results and reinforces the conclusion that the sigma is well-below the Cobb-Douglas value of one

Aggregate production functions are reduced-form relationships that emerge endogenously from input-output interactions between heterogeneous producers and factors in general equilibrium. We provide a general methodology for analyzing such aggregate production functions by deriving their first-...

The value of the Slovak long-run elasticity substitution is relatively slow – about 0.10. It follows from the estimate of low-frequency econometric model. Econometric form is given by the capital demand derived from the first-order conditions of the firm maximizing its profit. Due to the...

Despite its long pedigree, studies on the role of the substitution elasticity between capital and labor mostly assume a homogeneous labor market. This paper extends this literature by considering a heterogeneous labor market with capital-skill complementarity. Technological advancement, global...
