dynamic capabilities as context the role of decision system and structure in this article we look at some implications of the role of dynamic capabilities in enabling strategic decision making in the firm it is argued that properly specifying questions relating to dynamic capabilities raises questions of what is involved in strategic decisions which in turn inevitably involves or should involve consideration of the complementary roles of non decomposability and decision processes this entails a reappraisal of how and where established frameworks may or may not be of relevance in this context and invites consideration of how an economics perspective should be framed to deal with such issues copyright 2010 the author 2010 published by oxford university press on behalf of associazione icc all rights reserved oxford university press

gendered occupational differences and earnings gaps in globalising urban economies the case of tel aviv the major theoretical purpose of the paper is to investigate the implications of globalising and restructuring urban economies on gender related differences in occupational distribution and earnings within the urban context the study uses data from national censuses 1983 and 1995 and a labour force survey of 2001 in israel to investigate the evolution of gender gaps in tel aviv the findings that point to the erosion of advantages in the globalising and restructuring urban economy compared with the nation as a whole may indicate new potential sources of gender inequality the theoretical implications for both the restructuring and globalisation theses and the study of sources of inequality among men and women are discussed

status effects and environmental externalities abstract this paper examines a static competitive economy where the production of a consumption good generates pollution that adversely affects human welfare preferences are defined over consumption leisure pollution and economic status each person s status increases with her own consumption but decreases with the average consumption of society the achievement of a pareto efficient resource allocation requires a consumption tax to offset the incentive to overconsume in the pursuit of enhanced status in contrast with standard prescriptions the efficient pollution tax generally exceeds the sum of individuals marginal willingness to pay for pollution abatement these findings remain unaltered when preferences are modified to incorporate altruistic concern for others well being altruism however suggests a potential role for government intervention to achieve a desirable i e pareto efficient distribution of welfare between individuals

double co2 and beyond benefits costs and compensation abstract economic decisions over what action if any to take concerning the greenhouse effect tend to revolve around the social discount rate implicitly the debate concerns how to attribute intertemporal weights to welfare and implies a moral stance that is rarely given explicit recognition refocusing on the outcomes of current actions emphasises the role of compensation a conflict is apparent between the view that the current generation need be unconcerned over the loss or injury caused to future generations because they will benefit from advances in technology investments in both man made and natural capital and direct bequests and the requirement to avoid harming the innocent changes in units of welfare cannot be viewed as equivalent regardless of their direction in general doing harm is not cancelled out by doing good the result is a rejection of the potential compensation principle which underlies the current economic stance and a reconsideration of the acceptability of compensation altogether the concept of human rights and a non utilitarian perspective are used to show how cost benefit analysis denies the existence of inalienable rights and economics limits the moral considerability of harm

information order and knowledge in economic and ecological systems implications for material and energy use abstract ecological and economic systems are open systems that require energy to change the thermodynamic states of materials from naturally occurring to more valued forms these changes are accompanied by information flows and changes in the order of systems and their surroundings in this paper thermodynamics is used to assess these system changes and relate them to the knowledge present in a system particular emphasis is given to 1 the fundamental relationships among material energy and information flows and changes in order and knowledge 2 the role of equilibrium and non equilibrium thermodynamics in assessing system change 3 the increasing role of material and energy flows through economic systems and 4 the necessity for improved societal valuation of these flows

welfare regimes family supportive policies and women s employment along the life course this article examines women s employment patterns during thechild rearing period and the consequences of those patterns for earnings later in life in 12 industralized countries this study proposes an analytic framework that combines welfare regime and gender specific policies to explain country differences the findings presented here suggest that institutional arrangements mediate the costs to women s part time and intermittent employment within welfare regimes employment continuity is highest among countries in which the state provides support for working mothers furthermore this study finds that lower support for mothers employment is associated with higher wage penalties to employment discontinuity

experiments on the difference between willingness to pay and willingness to accept comment reply willingness to pay wtp and willingness to accept wta measures of welfare change have been found to differ substantially when elicited from surveys or experimental market transactions conventional economic theory suggests that the difference between wtp and wta should be smaller than those observed in empirical tests this study focuses on the hypothesis that the availability of substitutes for the good being evaluated affects the difference between the two measures the results suggest that the existence of a substitute does reduce the difference between wtp and wta however the difference between these two measures is significant with or without substitutes

measuring the existence value of wildlife reply we know little about the motives underlying individual responses to contingent valuation cv questions concerning the existence of wildlife yet motives are important because they determine how the resulting value estimates should be interpreted and used in making management decisions for example zero bids are very common in cv but these are often protests that do not represent zero valuation for the resource itself protest zero bids may be particularly prevalent in wildlife existence value studies because some people may view trade offs between money and wildlife as unethical or immoral if protest zero bids are not interpreted correctly existence value estimates obviously will be biased the motives underlying positive cv bids also matter unfortunately these motives have received much less research attention and so may be more controversial our study of wildlife values in new england suggests that many respondents who gave positive bids were motivated by ethical concerns altruism or the desire to do their fair share concerns that indicate they used decision making processes inconsistent with the neoclassical paradigm stevens et al 1991 cv results may therefore fail to measure the economic value of existence in traditional terms the bergson tintner samuelson formulation presented by kohn 1993 is useful in this context because it attempts to disentangle behavior motivated by ethical concerns about existence from preferences about wildlife use each individual is assumed to wear two hats one as citizen the other as consumer from this perspective citizens express social values which may be ethically driven while economic values are expressed by consumers kohn suggests that we make use of this distinction by first asking respondents as citizens to make implicit trade offs between income and the preservation of wildlife respondents are then asked about their willingness to pay for the option of consuming wildlife while this is an interesting proposal the bergson tintner samuelson framework is only one of several alternative theories about behavior involving ethical considerations for discussion these theories can be classified into three groups a theories of social or group interest b natural rights and c theories based upon the neoclassical model of self interest social interest theories include the bergson tintner samuelson formulation outlined by kohn and the dual utilities model proposed by margolis 1982 margolis suggests that people are motivated by two basic concerns a self interest and b social or group interest social interest which pertains to the welfare of society as a whole is assumed to be governed in part by ethics moral duty and commitment expressions of social interest include charity participation in the political process voting and contributions for the provision of public goods margolis maintains that the neoclassical theory of self interest generally fails to adequately explain individual behavior about social interests and he proposes a dual utilities model of individual preferences in which people have irreducibly distinct social and private preferences unlike the framework proposed by kohn there is no grand maximum where social value is traded off against private value rather individuals are assumed to allocate income between social and private preferences so as to do their fair share for the welfare of society as a whole con

on the intergenerational allocation of natural resources it is known hartwick and others that under standard assumptions a society that invests in reproducible capital the competitive rents on its current extraction of exhaustible resources will enjoy a consumption stream constant in time it is shown here that this result can be interpreted as saying that an appropriately defined stock of capital including the initial endowment of resources is being maintained intact and that consumption can be interpreted as the interest on that patrimony this seems like a useful rule of thumb for policy

threshold effects and incentives for the conservation of biodiversity biological diversity is a central component of the stock of natural capital on which all economic development is based other things being equal loss of biologically diversity implies loss of development potential and its conservation through sustainable use or outright protection implies the protection of that potential one characteristics of biodiversity loss of especial importance is that biodiversity loss more than any other current environmental problem is associated with ecological threshold effects the paper explores the implication of this characteristics for the properties of a biodiversity conservation strategy

valuing public goods with the contingent valuation method a critique of kahneman and knetsch the social stakes in the use and abuse of the contingent valuation method cvm are very high recent developments in environmental law have elevated the cvm to the status of a refutable presumption in cases brought under certain statutes it is no longer adequate for economists to sniff at the continued popularity of the cvm in such cases it is instead incumbent on economists to come to some conclusions as to the domain under which the cvm may or may not be correctly applied one should not expect a simple thumbs up or thumbs down assessment in this matter such an expectation would be naive with respect to the inherent complexity of the issue not to mention the financial incentives that expert witnesses might have to breed as if controversy in an adversarial legal system in this context the strong admonitions of kahneman and knetsch 3 kk against the casual use of the cvm must be carefully examined they present what they believe to be evidence to support the claim that the cvm suffers from an embedding effect and that any reported willingness to pay wtp is best interpreted as the purchase of moral satisfaction rather than as a measure of the value associated with a particular public good i argue that their evidence is insufficient to test the implied hypotheses that it is incorrectly reported and that it is in large measure fully consistent with received economic theory

is sustainability optimal examining the differences between economists and environmentalists abstract this paper examines a number of possible explanations for the apparent differences between economists and environmentalists concerning economic growth and sustainable development some of the differences are well known and relate to issues such as resource scarcity intergenerational equity and the composition of social capital however our analysis finds that while economic notions of optimal growth and the techniques of benefit cost analysis have important advantages for evaluating complex tradeoffs because they are quantifiable they may have potentially serious drawbacks as well the paper focuses on two potential sources of bias in the use of welfare economics for social choice first there is a conservative reinforcement in benefit cost analysis which is likely to produce biases against policy interventions to protect a degraded environment second and perhaps more importantly the aggregation of individual willingness to pay as a measure of social benefits is shown to be invalid in the case of positional goods where the demand for the good reflects the desire of individuals to raise their own relative standing this error may cause the economic calculus to be biased against non positional goods including non rival goods such as environmental resources these biases further complicate the already strained assumptions in utilitarian based welfare economics that by relying on revealed preference and consumer sovereignty are unable to distinguish between or apply different weights to the satisfaction of different categories of preferences furthermore because the dynamic consequences of even small biases in judging social optimality may give rise to large social costs or advance an unsustainable path there is a danger in relying solely on a potentially biased measure of welfare as a basis for guiding social choice the paper concludes by suggesting that efforts to correct these drawbacks of economic analysis are likely to result in approaches to sustainable development that narrow the apparent differences between economists and environmentalists

entropy structure and organisational change abstract the paper sets out a basis for rigorous thermodynamic characterisation of structural change and of organisational interdependencies between economic and environmental processes many attempts have been made to exploit entropy as a generic explanatory variable it has widely been proposed that entropy is a measure of the level of dis order of a system of how mixed up things are then as organisation is often thought synonymous with some notion of order it has been a small step to propose that increasing organisation is the converse of increasing entropy another suggestion has been that social system structure and change can be explained in terms of a tendency towards maximum entropy production the lotka principle of maximum energy dissipation all these notions must be rejected the putative entropy order connection has its inspiration in boltzmann s probabilistic interpretation of thermodynamic entropy as a measure of microscopic disorder this order principle is simply not applicable under conditions far from thermodynamic equilibrium prigogine conditions which prevail for all important economic and ecological processes under such conditions the relationship between entropy production and changes in structure or organisation is multi faceted and situation specific attempts to account for the specificity of societal activities in terms of a generic scalar measure of organisation or dissipation are largely after the fact and in no way do away with the need for analysis of institutional and ethical dimensions of human action in their own right when properly allied to institutional analysis however the far from equilibrium thermodynamics furnishes a rich impetus for a coevolutionary perspective in ecological economics with promise of incisive treatments of in particular issues of system environment codependency and of the time in determinacies of economy environmental change

towards an ecological economics of sustainability abstract persistent disagreement both as to the interpretation to be given to sustainability and as to the relation between ecological and economic sustainability has hindered the development of an ecological economics of sustainable resource use this paper identifies the main concepts of sustainability deriving from the two disciplines in order to explore the difference implied by an ecological approach to the problem it is argued that present economic and ecological approaches are largely disjoint and that they address basically different phenomena by combining the efficiency requirements of what is usually thought of as economic sustainability with the stability requirements of an ecological approach it is shown that an intertemporally efficient allocation of resources that satisfies the conditions for constant levels of consumption is not necessary to assure ecological sustainability ecological sustainability requires that the allocation of economic resources should not result in the instability of the economy environment system as a whole

efficiency sustainability and global warming abstract economic analyses of global warming have typically been grounded in the theory of economic efficiency such analyses may be inappropriate because many of the underlying concerns about climate change are rooted not in efficiency but in the intergenerational allocation of economic endowments a simple economic model is developed which demonstrates that an efficient economy is not necessarily a sustainable economy this result leads directly to questions about the policy relevance of several economic studies of the issue we then consider policy alternatives to address global warming in the context of economies with the dual objectives of efficiency and sustainability with particular attention to carbon based taxes

gender and the new inequality explaining the college non college wage gap the new inequality is often characterized by the increasing wage gap between workers with a college education and those without yet although the gap in hourly wages between college educated and non college educated women is high and rising the topic has been overshadowed by research on gender inequality and wage inequality among men using the 1990 5 percent public use microdata samples independent sources of macro data and controls for individual human capital characteristics i examine the association between the college non college wage gap and key aspects of local economic conditions for women and men while the college non college wage gap among women is comparable in size to the gap among men significant gender differences emerge in the underlying sources of high wage gaps in over 500 labor markets across the united states compared with men flexible and insecure employment conditions e g joblessness casualization and immigration are more important in fostering high wage gaps among women than are technology trade and industrial composition the prevailing explanations of rising wage inequality over time based on these gender differences i reconsider the debate on labor market restructuring and inequality and discuss a new analytical focus on differences in within gender inequality

do existence values for cost benefit analysis exist the use of the contingent valuation method to generate estimates of existence value for input to cost benefit analysis requires that individuals have utility functions defined over the relevant arguments the validity of the assumption that the required utility functions generally exist has been questioned it has been argued that some individuals will respond on the basis of lexicographic preference orderings it has also been argued that some individuals do not consider that market or individual willingness to pay criteria are appropriate where existence value type issues are at stake the paper considers survey evidence bearing upon these arguments it is concluded that the evidence is consistent with the view that it is incorrect to proceed on the assumption that individuals generally satisfy the assumptions required for the existence of existence values for use in cost benefit analysis

inter fuel substitution technical change and the demand for energy in the uk economy a model for energy demand based on a translog cost function is formulated unlike previous studies technical progress is modelled by means of stochastic as opposed to deterministic trend components the model is estimated using quarterly uk data for four economic sectors and forecasts of the future level of demand are made

willingness to pay and willingness to accept how much can they differ comment i agree with the point made by edoh y amiran and daniel a hagen 2003 that there can be a substantial or even infinite divergence between the wta and wtp for a public good even where there is a nonzero elasticity of substitution between market goods and the public good provided that the indifference curves are asymptotically bounded with respect to market goods in the manner they describe this is an important point they are also correct to point out that the elasticity of substitution is a local concept whereas their asymptotic boundedness condition applies also for discrete changes my 1991 paper used a local analysis because it was following the structure of the analysis in robert d willig 1976 and alan randall and john r stoll 1980 i wanted to show that while randall and stoll appeared to extend willig s local result on wta versus wtp from price changes to changes in the quantity of a public good the relevant elasticity was in fact different and involved the substitution elasticity as well as the income elasticity i view these points by amiran and hagen as not two separate results but essentially the same result their asymptotic boundedness condition generalizes my zero elasticity of substitution condition to discrete changes the asymptotic boundedness condition can be expressed as follows assuming a bivariate utility function u x q and given a reference point x q associated with a reference utility level u u x q there exists some q q such that for all q q there exists no x such that u x q u in other words no amount of x can substitute for the reduction in public good from q to q q in the case of a zero elasticity of substitution q q but as amiran and hagen show in their theorem 1 this is unnecessarily restrictive when dealing with a discrete reduction in q furthermore their theorem 2 can be viewed as a special case of their theorem 1 in which q 0 which makes q an essential commodity it is well known in consumer theory that the wta to avoid the loss of an essential market good is infinite their theorem 2 extends this result to the case of an essential nonmarket good but as their theorem 1 shows essentialness is not necessary for an infinite wta the boundedness condition is the key and this implies a fundamental lack of substitutability between money market goods and the public good

economic inequality new methods for new trends two positions dominate the debate over the recent increases in economic inequality in the united states the job skill mismatch thesis attributes rising inequality to growth in the number of high skill high wage jobs that leaves less skilled workers behind the polarization thesis in contrast argues that the service shift generates growth in the number of both high wage and low wage jobs and declines in the middle standard summary measures of distributional inequality cannot discriminate between these depictions of where job growth is occurring we propose new methods for measurement that provide both summary and detailed information about the distributional shifts in earnings and aframework for statistical inference using data from the curent population survey cps on yearly earnings from 1967 to 1987 we show that the trends in distributional inequality vary considerably by race gender and time while the evidence provides more support for the polarization argument this thesis needs refinement if it is to account for the variations in changing inequality observed here

accounting for changes in tastes health concerns are thought by many to have shifted consumption away from red meats though econometric evidence is mixed testing for structural change is difficult especially when one time series is used for both estimating demand equations and testing their stability specification errors may suggest a shift where none has occurred using nonparametric demand analysis we find that meat consumption patterns in the united states and australia can be explained using only relative prices and expenditures only imposing particular functional forms can reverse the conclusion suggesting that specification errors in econometric demand studies can account for findings of taste changes

a general framework for the analysis of preference variation the traditional approach to changing preferences introduced a vector of shift variables in the utility function but was confronted with the problem of specifying the effects of changes in these variables on the marginal utilities the new theory of demand introducing intervening variables characteristics basic commodities offers an attractive and psychologically richer way of describing preferences changes it is however difficult to operationalise and the use of shadow prices in a two stage decision procedure raises some difficult theoretical problems in this paper we try to integrate the two approaches we start from the traditional framework but use the specification of the household technology to specify changes in the marginal utilities of the market goods in this way we get a very general model from which most existing definitions of preference changes can be derived as special cases this is illustrated with an analysis of habit formation the effect of quality changes in a lancaster setting and the content of advertising messages use of the model makes it possible to gain some new insights in each of these cases

energy capital substitutability complementarity the dichotomy abstract changes in the price of energy affect not only the demand for energy but also the rates of capital formation and labour utilization these changes depend on the functional relationship between energy and the primary factor inputs in particular the relationship between energy and capital has been characterized by major conflicting evidence time series data classify the two inputs as complements by contrast pooled cross section studies conclude that capital and energy aresubstitutes in the production process in this case higher priced energy will stimulate the demand for investment while several reconciliation attempts on this disparity deserve marked attention the most prominent explanation is that time series studies reflect short term relationships and cross section analyses capture long term effects

measuring the existence value of wildlife what do cvm estimates really show two research programs are brought together to contribute to the growing body of work on alternatives to standard welfare based approaches to environmental valuation and policy the first is the theoretical literature undermining the new welfare

limits to substitution and irreversibility in production and consumption a neoclassical interpretation of ecological economics abstract there are many methodological approaches within ecological economics one of the principal modes of analysis is a modified version of the standard neoclassical model this paper examines the parallels which emerge between the ideas of some ecological economists concerning production and the ideas of others concerning consumption when these ideas are interpreted in the neoclassical paradigm it is well known that ecological economics is characterized by arguments concerning limits to substitution between inputs energy natural capital etc vs manufactured capital labor etc in production and the implications these have for sustainability however various authors have also expressed concerns regarding limits to substitution in consumption either between environmental assets and other goods or between basic needs commodities and other goods though the specific reasons for non substitution are different in the production and consumption cases the underlying theme is that individual commodities and other inputs have unique physical or other properties which make them poor substitutes ideas about irreversibility in production and economic development are also prominent in ecological economics likewise many authors have argued for similar irreversibilities in consumption behavior in analogy to the term technological change i coin the term preferential change to describe these phenomena the linking themes in this case are that the economy environment system is evolutionary in character and that external effects intended and unintended consequences of actions or processes imposed on other parties or resources are all pervasive
