Recently economists have become interested in why people who face social dilemmas in the experimental lab use the seemingly incredible threat of punishment to deter free riding. Three theories with evolutionary microfoundations have been developed to explain punishment. We survey these theories and use behavioral data from surveys and experiments to show that the theory called social reciprocity in which people punish norm violators indiscriminately explains punishment best.JEL Classification:

Synopsis Classification is an important activity that facilitates theory development in many academic disciplines. Scholars in fields
such as organizational science, management science and economics and have long recognized that classification offers an approach
for ordering and understanding the diversity of organizational taxa (groups of one or more similar organizational entities).
However, even the most prominent organizational classifications have limited utility, as they tend to be shaped by a specific
research bias, inadequate units of analysis and a standard neoclassical economic view that does not naturally accommodate
the disequilibrium dynamics of modern competition. The result is a relatively large number of individual and unconnected organizational
classifications, which tend to ignore the processes of change responsible for organizational diversity. Collectively they
fail to provide any sort of universal system for ordering, compiling and presenting knowledge on organizational diversity.
This paper has two purposes. First, it reviews the general status of the major theoretical approaches to biological and organizational
classification and compares the methods and resulting classifications derived from each approach. Definitions of key terms
and a discussion on the three principal schools of biological classification (evolutionary systematics, phenetics and cladistics)
are included in this review. Second, this paper aims to encourage critical thinking and debate about the use of the cladistic
classification approach for inferring and representing the historical relationships underpinning organizational diversity.
This involves examining the feasibility of applying the logic of common ancestry to populations of organizations. Consequently,
this paper is exploratory and preparatory in style, with illustrations and assertions concerning the study and classification
of organizational diversity. 相似文献

Tests of convergent validity and procedural invariance were used to investigate whether individuals lacking direct experience with a commodity can provide valid responses to contingent-valuation questions eliciting ex post use values. Convergent validity between samples with and without experience was shown to hold for dichotomous-choice responses, but not for open-ended responses. 相似文献

Price caps have been shown to have incentive properties superior to traditional rate of return regulation. Average-revenue-lagged regulation (ARL) is attractive in that steady-state prices are known to be efficient. We show that the ARL scheme can be manipulated by the firm so as to yield the unregulated global profit maximum. While tests exist that can provide the regulator with evidence of this strategic behavior, we also demonstrate that the unregulated global profit maximum will not be attainable if Laspeyres (L) regulation is employed.Jel classification: L43, L51I would like to thank Michael Crew and an anonymous referee for their extremely helpful suggestions. 相似文献

The essay analyzes in an overlapping-generations model, to which extent a pay-as-you-go pension system will be the outcome
of majority voting, given specific institutional set-ups. Clearly, the vote of an active person depends on his expectations
about how the present decision (i.e., his contribution) is linked to the future (i.e., his benefits), when he will be retired.
In the paper we employ the assumption of a basic social contract where each active voter's future benefits are positively
related to his contributions. It is shown that in this framework a steady-state with a positive (though lower than optimal)
level of the pension system exists, even if a new majority decision about the system takes place every period. 相似文献

Sources of gains from international portfolio diversification 总被引:1,自引:0,他引:1
This paper looks at the determinants of country and industry specific factors in international portfolio returns using a sample of forty eight countries and thirty nine industries over the last three decades. Country factors have remained relatively stable over the sample period while industry factors have significantly increased during the last decade and dropped again since 2000. The importance of industry and country factors is correlated with measures of economic and financial international integration and development. We find that financial market globalization is the main driving force behind the changes in relative magnitude of the different shocks. Country factors are smaller for countries integrated in world financial markets and have declined as the degree of financial integration and the number of countries pursuing financial liberalization has increased. Higher international financial integration within an industry increases the importance of industry factors in explaining returns. Economic integration of production also helps in explaining returns. Countries with a more specialized production activity have higher country shocks. 相似文献

The replicating portfolio (RP) approach to the calculation of capital for life insurance portfolios is an industry standard. The RP is obtained from projecting the terminal loss of discounted asset–liability cash flows on a set of factors generated by a family of financial instruments that can be efficiently simulated. We provide the mathematical foundations and a novel dynamic and path-dependent RP approach for real-world and risk-neutral sampling. We show that our RP approach yields asymptotically consistent capital estimators if the chaotic representation property holds. We illustrate the tractability of the RP approach by three numerical examples. 相似文献
