Changes in total surplus are traditional measures of economic welfare. We propose necessary and sufficient conditions for
rationalizing individual and aggregate consumer demand data with individual quasilinear and homothetic utility functions.
Under these conditions, consumer surplus is a valid measure of consumer welfare. For nonmarketed goods, we propose necessary
and sufficient conditions on input market data for efficient production, i.e. production at minimum cost. Under these conditions
we derive a cost function for the nonmarketed good, where producer surplus is the area above the marginal cost curve.

This paper introduces the idea of “robust political economy.” In the context of political economic systems, “robustness” refers
to a political economic arrangement's ability to produce social welfare-enhancing outcomes in the face of deviations from
ideal assumptions about individuals' motivations and information. Since standard assumptions about complete and perfect information,
instantaneous market adjustment, perfect agent rationality, political actor benevolence, etc., rarely, if ever actually hold,
a realistic picture and accurate assessment of the desirability of alternative political economic systems requires an analysis
of alternative systems' robustness. The Mises-Hayek critique of socialism forms the foundation for investigations of robustness
that relax ideal informational assumptions. The Buchanan-Tullock public choice approach complements this foundation in forming
the basis for investigations of robustness that relax ideal motivational assumptions.

I consider whether entrepreneurship is a distinct category within economic theory. More generally, I consider the links between discussions of entrepreneurship and philosophic debates over the nature of the aesthetic. For instance, Kant's attempt to elevate the category of the aesthetic has much in common with Kirzner's attempt to elevate the concept of the entrepreneur. Shackle's theory of choice refers very directly to the notion of the aesthetic. Theories of the aesthetic and theories of the entrepreneur have common strengths and weaknesses. 相似文献

In some of their papers published in the 1950s, Herbert Simonand Sidney Siegel responded to the so-called mixed strategyanomaly in ways which deserve more attention. They producednot only (i) immediate defences of the economic theory of theirown time, but also (ii) ideas and solutions that have laterturned out to be significant contributions to the developmentof the economic theory of choice and decision-making and theseparation of experimental economics from experimental psychology.These observations suggest that economics can be more responsiveto empirical anomalies than has been assumed. Furthermore, knowledgeof the desirable responsiveness to anomalies can provide meansof avoiding the non-desirable immunity to anomalies. 相似文献

We examine the effects of public ownership and regulatory agency independence on regulatory outcomes in EU telecommunications.
Specifically, we study regulated interconnect rates paid by entrants to incumbents. We find that public ownership of the incumbent
positively affects these interconnect rates, and suggest that governments influence regulatory outcomes in favor of incumbents
in which they are substantially invested. However, we also find that the presence of institutional features enhancing regulatory
independence from the government mitigates this effect. In order to study regulatory independence, we introduce a new cross-country
time-series database—the European Union Regulatory Institutions (EURI) Database. This database describes the development of
institutions bearing on regulatory independence and quality in telecommunications in the 15 founding EU member states from
1997 to 2003

Summary. We present a new class of rules named augmented serial rules for the provision of an excludable public good. First, we characterize this class by the four axioms of strategy-proofness, envy-freeness, access independence, and nonbossiness. Second, we identify two important subclasses by imposing an additional axiom: (i) anonymous augmented serial rules by anonymity, and (ii) Moulins serial rule by individual rationality.Received: 31 December 2002, Revised: 9 June 2004, JEL Classification Numbers:

We consider a leader and a subordinate he appoints who work in a team. The public observes the organization’s performance, but not the separate contribution of the leader or of the subordinate. The leader may therefore claim credit for the good work of his subordinate. We find conditions which induce the leader to claim credit (both truthfully and untruthfully), and the conditions which lead the leader to appoint a subordinate of low ability.JEL Classification:

For the maintenance and development of a disaggregated econometric model, the present paper deals with some aspects related to the identification of important intermediate transactions. First, some methodological aspects related to earlier works are discussed. By comparing the properties of different selection methods based on the recent West German input–output table, the calculations confirm the common finding that the necessary level of endogenization can be bounded meaningfully by an a priori investiga tion of the intersectoral transactions. This is also valid if the selection method considers restrictions that deal with the consistence of input–output tables and if some broader error criteria are applied. The main result of the empirical applications seems to be that some attention should be paid to temporal changes of important coefficients. 相似文献
