To the metaphors of software engineering and software physics can be added that of software geography. We examine the physical and economic aspects of the Software Glacier (once an innocent bubbling brook, now a vast frozen mass of applications imperceptibly shaping both the Hardware Shelf below and User City above), Quantum Planet (colonization of which could be fruitful if and when it becomes...

This paper studies global stability of spatial configurations in a dynamic two-region model with quadratic adjustment costs where rational migrants make migration decisions so as to maximize their discounted future utilities. A global analysis is conducted to show that, except for knife–edge cases with symmetric regions, there exists a unique spatial configuration that is absorbing and globally...

Most of the literature argues that competitive analysis has nothing interesting to say about location. This paper argues, to the contrary, that a competitive model can have something interesting to say about location, provided that locations are not identical and transportation costs are not zero. To do this, it constructs a competitive intertemporal general equilibrium model and applies it to ...

comprehensive set of countries with populations of 1 million or more in 1994. In total, our data include 5.507 billion people, of an estimated global population in 1994 of 5.601 billion, or 98.3 percent of the total world population. The main countries missing from the sample, because of unavailability of data, are: Afghanistan, Albania, Bosnia & Herzegovina, Cambodia, Cuba, Iraq, Lebanon, and ...

Only a few research papers have analysed the spatial distribution of economic activity in Ireland. There are a number of reasons for this, not least the fact that comprehensive data on the location of economic activity by sector across all sectors has not been available at the highly disaggregated spatial level. This paper firstly establishes the geographic distribution of employment at the 2 d...

The field of New Economic Geography (NEG) aims at explaining agglomeration based on increasing returns, monopolistic competition and international factor mobility. Deviating from existing approaches, this paper constructs a theoretical model based on capital market frictions. Firms compete monopolistically, but are lead by managers subject to moral hazard. Incentivizing managers is cheaper in r...

Recent decades have seen momentous changes in the economic geography of the world. Political transitions and economic liberalization have brought formerly closed countries into the world economy. In Richard Freeman’s phrase, this has amounted to a “doubling of the world labor force.” The collapse of communism in the Soviet bloc brings 260 million workers into the world labor force; the opening ...

Will the Internet redefine the "core" and the "periphery," creating a new geography, with neighborhoods connected not with streams and roads but with wires and microwave transmissions? An analogy to previous transportation and communications improvements is frequently made today: the transportation revolution of the 20th century permitted the deagglomeration of much physical production, and the...

The accelerating rates of international trade, travel, and transport in the latter half of the twentieth century have led to the progressive mixing of biota from across the world and the number of species introduced to new regions continues to increase. The importance of biogeographic, climatic, economic, and demographic factors as drivers of this trend is increasingly being realized but as yet...

Introduction Geography first started with simple writing. But today, this science has gained a lot of potentials and with its technical tools which has at hand, has new specialized trends and is training new experts and specialists. Hence, in the present age, especially in Iran, geography is referred to as (interdisciplinary science), because it both studies natural sciences and human sciences...
