Izumi Kitagawa, Economic Structure of Log Production

Production Structure and Economic Fluctuations

We aim at contributing to the debate on the mechanisms and properties of economic fluctuations. We consider a crucial aspect among many thought to influence this ubiquitous and extremely relevant phenomenon: the interaction structure that characterises the organisation of production, that is, the production relation among sectors of a system. We build — and simulate — a very simple model repres...

Log-linearization of Stochastic Economic Models

This short note studies formally the common practice of log-linearizing stochastic economic models. We make precise the conditions under which stability of the original model can be inferred from that of the linearized model. A transformation to recover the stochastic equilibrium of the former from that of the latter is provided.

Economic Appraisal of Shale Oil Production

The security, political and economic impacts of shale oil and gas, has changed the supply side of international energy market. Different countries are looking for feasible technology of shale oil production. In this paper after studies on the technical and economic aspects of shale oil production, we studied on the CAPEX and OPEX of shale oil production in a feasibility study framework in order...

Economic Geography and Regional Production Structure: An Empirical Investigation bY

There are two principal theories of why countries or regions trade: comparative advantage and increasing returns to scale. Yet there is virtually no empirical work that assesses the relative importance of these two theories in accounting for production structure and trade. We use a framework that nests an increasing returns model of economic geography featuring “home market effects” with that o...
