modelling strategy of new economic geography

Using new tools--in particular, modeling techniques developed to analyze industrial organization, international trade, and economic growth--this "new economic geography" has emerged as … The RHOMOLO model is a dynamic spatial general equilibrium (DSGE) modelling framework capturing 270 NUTS2 regions in EU-27, and decomposing the economy into 6 sectors. The different ways in which these changes in the economic environment impact the rest of the country are easily tracked and quantified with our model, showing its use a policy evaluation instrument. The standard errors (computed using Monte Carlo methods) cast some doubt on the reliability of these estimates, however. We started by placing the theory in a context of preceding theories, both earlier work on spatial economics and other children of the monopolistic competition ‘revolution.’ Next, we looked at the theoretical properties of these models, especially when we allow firms to have different demand functions for intermediate goods. After a thorough description of Fujita and Thisse (2002), we introduce a different migration law à la Krugman (1991a). Finally, we used the theory to conduct a policy evaluation exercise concerning the construction of a railroad. A Competitive Model of Economic Geography Bryan Ellickson1 and William Zame2 1 UCLA, Los Angeles, CA 90049, USA ellickson@econ.ucla.edu 2 UCLA, Los Angeles, CA 90049, USA zame@econ.ucla.edu Abstract Most of the literature argues that competitive analysis has nothing interesting to say about location.

Using this procedure, we find parameter values that indicate increased sensitivity to distance and the presence of a shared border, relative to the first estimation. Employing the RHOMOLO model one can analyse how policy changes affect variables such as regional unemployment rates, participation rates, and regional non-market wage levels. We show that a fall in local wages sets off a chain of events, redistributing demand toward Illinois and its neighboring states, who enjoy cheaper inputs. By this strategy, generalizations have been made on the basis of few cases and many a … The research in new economic geography (NEG) suffers from discrepancies between its theory and empirics due to the different ways that the geography is treated.

But again these neighbors are worse off in the end, this time because national demand is shifted away from them, towards Illinois and Indiana.
