Question

write a review on the existence and growth of cities. Please be sure to think about how geography affects economic activity.

Answer 1

(a) Central drivers of urban population growth in industrialized economies. Secondly, the provision of transport and accommodation. Second, comforts. Thirdly, the effects of agglomeration, especially those relating to human capital and entrepreneurship. And fourthly, to particular cities or sectors, technology, and shocks. These drivers depend first on regressions of cross-city growth. The detection of causal factors in the transversal regression of city population growth is fraught with difficulties. Applications of this form of approach to cross-country sales growth per capita have been rightly criticized in the past.

Factors for urban population growth within a nation are therefore much smaller than the number of potential causes of world-wide income growth because several variables can be viewed as a first approximation, kept constant within a single country. Over the past decade, the city growth literature has also frequently discussed fundamental inferences, focusing in particular on instrumental variables. City growth factors are closely related to the main modeling methods used to research urban economics: a monocentric model for housing and transportation, a cross-city model that balances the differentials in services, models of micro-founded agglomeration economies for agglomeration effects and human resources, and random growth models for technology and sectoral shocks.

Some future engines of urban development have yet to be investigated. The greatest difference is the study of the impact of city and state governments, local policies and public finances. Moreover, several empirical results should be improved, and alternative empirical approaches should be established to validate them. While a compelling analytical framework that simultaneously explores all current drivers of urban growth is too ambitious a target, it is not satisfactory to investigate drivers of urban growth in isolation.

City development theoretically offers a unique insight into the wider problem of economic growth and technical innovation determinants.

(b) Place and environment, among other networks, have significant effects on income rates and revenue growth through their impacts on transport costs, disease burdens, and agricultural productivity. Geography also tends to influence decisions taken in economic policy. Many geographical regions that were not conducive to modern economic growth have high population densities and are experiencing rapid population growth particularly disadvantageous are regions far from coasts and ocean-navigable rivers, where the transportation costs of international trade are high, and tropical regions which carry a heavy disease burden. In addition, a significant portion of population growth in these geographically deprived areas is projected to occur over the next thirty years.
