The Theory of Socially Embedded Games: Applications and Extensions to Open and Closed Games 总被引:1,自引:0,他引:1
An earlier article, drawing on the mathematical theory of rules and rule complexes, extends and generalizes game theory (GGT). The theory has been used to conceptualize and analyze diverse social relationships, roles, and games as particular types of rule complexes.For instance, a social role, as a major basis of a parent's action in a game, consists of at least four key components – which are mathematical objects – in the determination of action: value complex, model of reality (including beliefs and knowledge bases), a repertoire of acts, routines, programs, and strategies, and modality, a role-specific algorithm for determining or generating action in game settings. This article applies and extends GGT in analyses of a market bargaining game (a type of open game) and of the classical game of prisoners' dilemma (a type of closed game). The applications show the concrete effects of social embeddedness on game structuring, game interaction patterns and outcomes, and social equilibria. 相似文献

This work draws on consumer and psychology research to explain sociocognitive aspects of product-market dynamics at a higher
level of specificity than prior research. The authors extend the field’s understanding of market-shaping shared knowledge
through a theory-informed discussion of how shared product knowledge comes to exist and how it changes as product markets
develop. They define shared knowledge as the aspects of product representations that are common across the minds of market
actors, making it possible for them to understand one another. The authors also discuss ways to track shared knowledge content
that is expressed in market narratives. As the characteristics of shared knowledge are explained and linked to stages of product-market
development, the authors develop a set of researchable propositions to guide future research. The theoretical arguments and
propositions in this article complement extant marketing strategy research by integrating individual-level consumer theory
with market evolution models.

We compare the performance of a wide set of regression techniques and machine-learning algorithms for predicting recovery rates on non-performing loans, using a private database from a European debt collection agency. We find that rule-based algorithms such as Cubist, boosted trees, and random forests perform significantly better than other approaches. In addition to loan contract specificities, predictors that refer to the bank recovery process — prior to the portfolio’s sale to a debt collector — are also shown to enhance forecasting performance. These variables, derived from the time series of contacts to defaulted clients and client reimbursements to the bank, help all algorithms better identify debtors with different repayment ability and/or commitment, and in general those with different recovery potential. 相似文献

Environmental Regulation and Substitution Between Sources of Pollution: An Empirical Analysis of Florida’s Storage Tanks 总被引:1,自引:0,他引:1
Stringent and very specific environmental regulations may spur behavioral responses by the regulated entities that can offset the intended pollution control goals. I empirically examine the effects of regulating underground storage tanks for petroleum products and hazardous substances, focusing on their possible substitution or complementarity with a less stringently regulated alternative, aboveground tanks. Longitudinal county-level tank data from Florida reveal that the relationship between underground and aboveground tanks changed, from one of complementarity to one of substitution, after the regulations were issued. Tank installations are affected by resident characteristics that enter in the firms calculus of the damages from leaks. 相似文献

Recent research in natural sciences shows that the dynamics in boreal forests are much more complex than what many models
traditionally used in forestry economics reflect. This essay analyzes some challenges of accounting for such complexity. It
shows that the optimal harvesting strategy for forest owners is history dependent and for some states of the forest, more
than one strategy may be optimal.This paper confirms earlier literature on shallow lakes and coral reefs and shows that this
kind of phenomena seem much more common than previously thought. They are valid for a wide range of ecosystems that cover
large surfaces and they do not depend on the choice of some specific function to model the non-linearity. There are also indications
that theses results could be obtained even for resources with concave growth if at least one species with non-linear growth
affects their dynamics. 相似文献

Assessing Voluntary Programs to Improve Environmental Quality 总被引:5,自引:1,他引:5
The last decade has seen a dramatic increase in the use of voluntaryapproaches (VAs) to environmental protection, which has
spurned agrowing literature on the relative merits of voluntary vs. mandatoryapproaches. This paper draws on that literature
to discuss both thetheoretical and empirical issues that arise in the evaluation orassessment of a particular VA. We consider
both the environmentaleffectiveness and the efficiency of this policy approach. Our aim is toaid policymakers in evaluating
a specific program or in thinking aboutthe use and design of a VA. We identify some key features that arelikely to increase
both the effectiveness and the efficiency of VAs. 相似文献

We analyze two cross-country data sets that contain information on attitudes toward trade as well as a broad range of socio-demographic and other indicators. We find that pro-trade preferences are significantly and robustly correlated with an individual's level of human capital, in the manner predicted by the factor endowments model. Preferences over trade are also correlated with the trade exposure of the sector in which an individual is employed: individuals in non-traded sectors tend to be the most pro-trade, while individuals in sectors with a revealed comparative disadvantage are the most protectionist. Third, an individual's relative economic status has a very strong positive association with pro-trade attitudes. Finally, non-economic determinants, in the form of values, identities, and attachments, play an important role in explaining the variation in preferences over trade. High degrees of neighborhood attachment and nationalism/patriotism are associated with protectionist tendencies. 相似文献

The slow and endogenous twist of economic macro-structure makes up an important evolutionary feature of capitalist economies,
and may be at the root of structural crisis. In this line, a Goodwinian growth model with increasing returns and profit-sharing
that tries to picture a simple scenario of the seventies crisis is considered. It is shown that the exhaustion of the Kaldor-Verdoorn
“productivity law” can entail, in a nonlinear framework, a “catastrophic” bifurcation from a “high” to a “low” growth path.
Slow/fast dynamical systems then allow one to formalize a multiple time-scales dynamics where the growth path is shaped by
the structural framework in which it takes place, but has also a long -un feedback. Structural change and crisis appear as
long term and endogenous outcomes. 相似文献

What is the cost of off-site hazardous waste disposal? In addition to paying for disposal fees and shipments costs, generators of hazardous waste can potentially be held liable for the cost of cleanup if the waste disposal site contaminates the environment after closure or abandonment and thus falls under the federal or state Superfund legislation. This paper empirically examines the sensitivity of individual hazardous waste generators to these categories of costs, exploiting the variation across states in factors influencing disposal costs, and in the structure of the liability imposed on waste generators under certain circumstances by state laws. We fit nested logit models to predict the waste management method (incineration or landfill disposal) and the state of destination for shipments of halogenated solvent waste used for metal cleaning in manufacturing and reported in the Toxic Release Inventory in 1988–1990. Waste generators respond to transportation costs and to proxies for current disposal costs. Generators also find the concurrent presence of strict and joint-and-several liability a deterrent, but this deterrent effect does not vary with the wealth of the firm or the volume of the waste shipped. 相似文献
