Abstract In Aristotelian understanding, political autarky does not imply individual isolation, but the order of all human relationships within (political) community. The final aim is ‘not-needing-anybody-else-anymore’, independent identity, collective-cooperative shaping and ordering life in immediate forms This includes a special way (i) basic social-anthropological elements, (ii) economic act...

When n agents decide to pool their private, decreasing returns technologies, single-path methods are a natural way to share joint output because of their strong incentives properties (Friedman, 2002). They are a non-anonymous generalization of the serial rule (Moulin and Shenker, 1992) sharing a production function along a prespeci…ed path. We show that only one of these methods satis…es volunt...

We study the problem of (eeciently) deleting such clauses from conjunctive normal forms (clause-sets) which can not contribute to any proof of unsatissability. For that purpose we introduce the notion of an autarky system, associated with a canonical normal form for every clause-set by deleting superruous clauses. Clause-sets where no clauses can be deleted are called lean, a natural generaliza...

We consider the algorithmic task of computing a maximal autarky for a clause-set F , i.e., a partial assignment which satisfies every clause of F it touches, and where this property is destroyed by adding any non-empty set of further assignments. We employ SAT solvers as oracles here, and we are especially concerned with minimising the number of oracle calls. Using the standard SAT oracle, log ...

This paper develops a two-country general equilibrium model to examine the costs and benefits of trade in differentiated products. It focuses on how the relative ability in exporting variety determines the welfare of each country. While the analysis suggests a new rationale for export-promotion, it also shows the possibility of overprovision of export variety. It is shown that the variety of co...

In this paper we analyze some policy implications of incompleteness of markets in trade models, where there is both inter-spatial and intertemporal trade between countries. We interpret the absence of intertemporal trade as an absence of intermediation services provided by both domestic and foreign service providers. For simplicity, we consider extreme cases where intertemporal intermediation s...

This paper provides a necessary and sufficient condition for the existence of nonautarkic contract in a risk sharing model with two-sided lack of commitment. Verifying the condition takes just one Gaussian elimination of a matrix. Published by Elsevier B.V.
