Strategy-proof and individually rational social choice functions for public good economies: A note

Summary. Serizawa [3] characterized the set of strategy-proof, individually rational, no exploitative, and non-bossy social choice functions in economies with pure public goods. He left an open question whether non-bossiness is necessary for his characterization. We will prove that non-bossiness is implied by the other three axioms in his characterization.

Testing alone is insufficient

Review of Economic Design - The fear of contracting a serious illness caused by a contagious disease limits economic activity even after reopening. Widespread testing alone will not alleviate this...     

Are price limits really bad for equity markets?

Despite widely documented criticisms, price-limit rules are present in many equity markets around the world. Using a game-theoretic model, we argue that, if the cost of monitoring a market is high, price-limit rules are beneficial. Empirical tests based on a cross section of 43 equity markets across five continents support our theoretical prediction. We find that the probability of the existence of price-limit rules is greater in markets that incur higher monitoring costs due to poorer business disclosure, more corruption and less efficiency in legal, regulatory and technological environments.     

Human extinction scenario frameworks

It is a natural human instinct to wonder about the future. Some have long speculated about the various events that could potentially lead to the extinction of the human race. While a dark subject, the point of exploring factors that could drastically impact the ability to sustain life on our planet has utility in preparing for events of this nature. It is in the spirit of learning how to change before catastrophe strikes that such wondering occurs.     

Managerial utility-maximizing operating decisions under compound demand risk

This paper examines the demand and cost conditions under which utility maximizing pricing-risk and advertising-risk relationships are determinate. The structure of the firm's demand uncertainty captures both uncertain customer arrivals and uncertain individual customer demand. In addition to standard demand restrictions and constant marginal cost, determinate results depend upon the degree of managerial risk-aversion, the correlation between individual demand and customer arrival disturbances, the firm's cost fixity, and bounded product differentiation effects of advertising. The symmetry between price-cuts and advertising as demand-increasing costs is extensively examined; firm equilibrium requires that price-cuts not be an inferior input for increasing demand.     

RCA indices,multinational production and the Ricardian trade model

The practice of using Revealed Comparative Advantage (RCA) Indices to determine the flow of goods trade among countries is well established. But an important issue that demands attention is whether the RCA indices reflect the essentials of comparative advantage theory. Deb and Basu Foreign Trade Rev 46(3):3–28, (2011) examined the consistency of alternative RCA indices with the Heckscher-Ohlin theory of comparative advantage, leaving scope for re-examination of the indices in the context of the Ricardian comparative advantage theory, which insists on relative factor productivity differences among countries contrary to Heckscher-Ohlin’s relative factor endowment differences. The other issue which has been overlooked in much of the existing literature is the importance of value-added trade. With the growing importance of global production chains, RCA indices based on gross export values may not portray an accurate picture of the underlying comparative advantage of countries. In this context, adjusting the RCA indices to incorporate domestic value-added in exports seems to be quite relevant. This paper explores the consistency of RCA indices based on domestic value-added in exports with the Ricardian theory of comparative advantage using a panel data approach. A brief review on the structures of alternative RCA indices is also provided. The Log-of-Balassa index is found to be the best performer in this empirical examination, although the deficiencies of the index for cross-country or cross-commodity comparison must be acknowledged. The index of Yu et al. Ann Reg Sci 43(1):267–282, (2009) does possess the latter feature but in our study its performance is quite poor and hence its consistency with the Ricardian theory of comparative advantage is questionable.
