This paper analyzes Walrasian general equilibrium systems and calculates the static and dynamic solutions for competitive market equilibria. The Walrasian framework encompasses the basic multi-sector growth (MSG) models with neoclassical production technologies in N sectors (industries). The...

Multi-sector growth (MSG) models have a special aura which is shared with Computable general equilibrium (CGE) models. Both of them, with their many sectors (industries, goods), are known as trying to convert Walrasian general equilibrium systems from an abstract economy representation into...

The Ricardian principle of ‘comparative advantage’ refers to relative costs (relative autarky prices) compared to another country. The relative cost (price) functions can be obtained directly from specified cost functions with global regularity properties. We derive the CES relative cost...

In this paper, we unify and extend the analytical and empirical application of the ”indirect addilog” expenditure system, introduced by Leser (1941), Somermeyer- Wit (1956) and Houthakker (1960). Using the Box-Cox transform, we present a parametric analysis of the Houthakker specification of...

A Schumpeterian growth model is constructed where R&D firms innovate to produce better versions of the products or imitate to copy existing innovations. Because firms cannot use their innovations or imitations as collateral, they finance their investment by issuing shares. Households save by...

The paper studies the contribution of human capital on economic growth through its impact on the rate of innovation by formulating an endogenous growth model that combines elements from Romer (1990), Aghion and Howitt (1992), and van Zon and Yetkiner (2003). Using a relatively broad concept of...

We study the negative correlation between natural resource-abundance and long-term income focusing on the savings-investment channel. We first present empirical evidence on this channel and then develop an OverLapping-Generations (OLG) model to study the issue. In this model, savings adjust...
