Conference paper (other academic/artistic)abstract
- We present a spatial computable general equilibrium model for which the Walras' law is employed to articulate the general equilibrium of a spatially separated economy while Wardrop's first principle is used to enuniciate the flow equilibrium on a general transportaion network. A price and transportation cost dependent input-output matrix is employed to alleviate the need for explicit supply and factor demand functions found in traditional Samuelson-Takayama-Judge spatial price equilibrium models. A detailed transportation network presentation is employed to more precisely predict commodity movements. A numerical example with constant net out matrix is also presented.

Affinities and Network Attributes in Sweden's Trade with Europe
- 1993
-
Reports (other academic/artistic)abstract
- A combined time series and cross-section data set is used in order to estimate network properties in the Swedish export to Europe. These properties are related to product cycle phenomena, and to a classification of commodities into product and price competitive. The estimated models combine a characterization of the nodes in the trade network with a representation of link attributes in order to explain the direction and amount of trade for different commodities.The study supports the assumption that differences in market perfornance is associated with differences in the demand for links with specific attributes. It also shows that trade patterns are influenced by economic and cultural affinities between pairs of countries.

Regionala utmaningar i det kommande Europa
- 1993
-
Other publication (pop. science, debate, etc.)abstract
- Europa har sedan 1 000-talet befunnit sig i världsekonomins centrum. En omfattande utbyggnad av nätverk för infrastruktur har tillsammans med institutionella och tekniska innovationer bildat grunden för denna dominans. Sedan början av 1900-talet har Europas dominerande position försvagats. Både inre och yttre faktorer kan förklara utvecklingen. Världskrigen och den barriär som järnridån inneburit förklarar delvis det förlorade initiativet. Allt hårdare konkurrens från USA och "Sydostasiens tigrar" är ytterligare en förklaring. Fortfarande är Europa en central länk i de internationella kommunikations- och handelsströmmarna. Frågan arom Europa efter revolutionen i öst 1989 kan återfå något av initiativet och hitta en ny roll i världsekonomin? Vad innebär i så fall "det postindustriella samhället" för Europas förmåga att skapa en dynamisk ekonomi?
