Skip to Content 29 no. Examples of some of these concepts are the gravity equation and the market potential function. The dispersing force is the local wage rate; this is reminiscent of the practice of multinational enterprises to relocate their manufacturing to low-wage countries. Our exercise in chapter 6 shows the results of a policy evaluation for which a large-scale economic geography model was built. By this strategy, generalizations have been made on the basis of few cases and many a … Modelling Migration and Regional Labour Markets: an Application of the New Economic Geography Model RHOMOLO jei capital, and knowledge capital, are accumulated endogenously between periods, according to the respective laws of motion.2 As in all recursive dynamic models with myopic expectations, RHOMOLO assumes that the behaviour of inter-temporally New Economic Geography models reach back to Krugman’s investigations on increasing returns to scale and trade in his papers of (1979) and (1980). Furthermore, transport investments have the potential to open up new corridors which are sustained over time, even beyond the useful life of the initial investment, thereby having lasting impact on economic geography. Furthermore, consumers in the North are better off because their access to services offered in the (more agglomerated) West has improved. In this thesis we look at economic geography models from a number of angles. We analyse the role of the migration law in the New Economic Geography models. 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. 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. From the first chapter, we learn that there exist a large number of progenitors to the current crop of economic geography models. This outcome can be used to argue against subsidies that would help ‘backward’ regions attract innovative firms in the hope of creating jobs.

BIRTA ... 0 downloads 39 … In particular, the effect of the surrounding geography on one state’s wages are hard to measure. Since 1990 a new genre of research, often described as the 'new economic geography', has emerged. It is our aim to study some of the migration laws utilized in Economic Geography, their dynamic properties and how their long-run predictions and stability change with the specificities of the economic models under consideration. • With the Krugman (1991a) migration law, a standard dynamic analysis is performed. The idea of continuous space modelling is not new in economic geography and spatial economics; it was already present in the studies of Weber on industrial location at … Modelling Migration and Regional Labour Markets: an Application of the New Economic Geography Model RHOMOLO: Authors: BRANDSMA Andries; KANCS D'ARTIS; PERSYN DAMIAAN HEDWIG LEO: Citation: Journal of Economic Integration vol.

We use two methods of estimation, one of which has been used before on a sample of countries worldwide (Redding and Venables 2001). Next, we simulate a fall in transport costs between the neighboring states of Illinois and Indiana. Each economy is disaggregated into six sectors. This paper proposes modelling the mechanisms of spatial distribution of economic activity on the microgeographic level, taking the location of each firm into account. 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. Our exercise in chapter 6 shows the results of a policy evaluation for which a large-scale economic geography model was built. Which region gets the innovative firms is decided by history, and cannot easily be changed. To purchase short term access, please sign in to your Oxford Academic account above. With the parametrized model of the United States, we run two counterfactuals involving changes in the (central) state of Illinois. Please check your email address / username and password and try again. After a thorough description of Fujita and Thisse (2002), we introduce a different migration law à la Krugman (1991a). In various branches of regional, cultural and historical geography, modelling strategies have distorted the subject by putting overemphasis on some topics and under emphasis on others. information spillover, the old new economic geography gains a new lease on life once you shift your focus to the developing countries that now account for most of the world’s economic growth. For those neighbors however, the total result turns out to be negative as they also face a drop in demand from Illinois. It is our aim to study some of the migration laws utilized in Economic Geography, their dynamic properties and how their long-run predictions and stability change with the specificities of the economic models under consideration.

We introduce a new estimation procedure that takes into account the general equilibrium properties of the model. That is, there exist situations in which a small change in the input-output parameters can have catastrophic consequences. The current base year of RHOMOLO, and to which structural parameters’ estimates are used to calibrate the model, is 2007. It does so through the exploration of linkages between centripetal and centrifugal forces, especially those of economies of scale. The model has a number of shortcomings, but did a reasonable job in tracking and quantifying the effects of six infrastructural projects. New economic geography is a term used in two ways in the international literature. Economic Geography publishes research that deepens the understanding of geographical drivers and implications of economic processes on the economy and society. Most users should sign in with their email address. However, many of the concepts that these models formalize have been known and used for a long time by other theories, albeit in a less formal manner. This is not unlike the property of standard core-periphery models to be sensitive to the level of transport costs at particular break- and sustain points.

RHOMOLO is constructed in the framework of a spatial computable general equilibrium, incorporating key aspects of new economic geography models (Krugman 1991). This chapter reviews the New Economic Geography ... NEG models recently developed in the literature, reviews their contributions systematically and compares different modelling strategies. We estimated the model using a dataset on US states, and computed a number of counterfactuals. New economic geography includes traditional thoughts about spatial economics such as urban economics, regional science, and economic location theory; introduces such concepts as region, location, and distance into economics; and uses increasing returns to scale, external economy, imperfect competition, and spatial agglomeration to explain the competitive advantages of national and regional … 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. Two aspects of New Economic Geography models are often singled out for criticism, especially by geographers: the treatment of geography, typically as a pre-given, fixed and highly idealized abstract geometric space; and the treatment of history, typically as ‘logical’ time (the movement to equilibrium in a model's solution space) rather than real history. Appraisal and Modelling Strategy Appraisal Periods Consultation ... demonstrate. • We study three frameworks to model inter-regional migrations. In the model, the global economy consists of regional economies in the EU and one aggregate economy capturing the rest of the world. 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. After a thorough description of Fujita and Thisse (2002), we introduce a different migration law à la Krugman (1991a). The standard errors (computed using Monte Carlo methods) cast some doubt on the reliability of these estimates, however. Using new tools--in particular, modeling techniques developed to analyze industrial organization, international trade, and economic growth--this "new economic geography" has emerged as … Finally, we used the theory to conduct a policy evaluation exercise concerning the construction of a railroad. The central thrust of the 'new economic geography' work to date, in short, has been driven by considera tions of modelling strategy toward an approach that concentrates on the role of market-size effects in generating linkages that foster geographical con centration, on one side, and the opposing force of immobile factors working against such concentra 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. The models in chapter 4 illustrate that the spatial equilibrium in economic geography models indeed depends on the technology that is used in production, and the different demand functions for intermediate inputs. The lesson from the New Economic Geography literature is that industrial geography outcomes can be highly sensitive to presence of sector- or firm-level economies of scale. There, Krugman employed the Dixit and Stiglitz (1977) framework on monopolistic com-petition and product diversity. This may be the effect of a dataset that is smaller and contains a few dominating regions. New Economic Geography 1 (NEG1) is characterized by sophisticated spatial modelling. By specifying a particular input demand function, we can eliminate the attraction between two groups of firms and observe that they move to different locations. An advantage of the formal microeconomic underpinning that the ‘new’ theory provides is that they may now be used in computations of consumer welfare, and embody explicit assumptions about economic behavior. Its insights range across different spatial scales, from the urban to the international. But again these neighbors are worse off in the end, this time because national demand is shifted away from them, towards Illinois and Indiana. P Krugman, What's new about the new economic geography?, Oxford Review of Economic Policy, Volume 14, Issue 2, June 1998, Pages 7–17, https://doi.org/10.1093/oxrep/14.2.7. The RHOMOLO model is based on the theories of general equilibrium, endogenous growth and new economic geography. Don't already have an Oxford Academic account? The new work is highly suggestive, particularly in indicating how historical accident can shape economic geography, and how gradual changes in underlying parameters can produce discontinuous change in spatial structure. This benefits the affected states, who with their cheaper products help the surrounding states as well. The same model can be used to show that in a growing economy, it is possible that all innovative firms locate in the same region, leaving the other region with the older manufacturing processes.

Unless these firms are relatively independent of other firms using related technology, these subsidies will have no lasting effect. • We propose a 2-region version of Romer (1990) where R&D workers can migrate. The new economic geography literature offers explanations of a number of phenomena that are empirically well documented – even obvious – such as the existence of cities and the presence of regional and international inequalities. Nonetheless, we can draw some useful conclusions from the extensions in chapters 3 and 4. Don't already have an Oxford Academic account?

It goes further by showing that a gradual change in these functions does not, in general, change the equilibrium except at a few crucial values. Massachusetts Institute of Technology, USA.
