towards an attention based view of the firm the central argument is that firm behavior is the result of how firms channel and distribute the attention of their decision makers what decision makers do depends on what issues and answers they focus their attention on what issues and answers they focus on depends on the specific situation and on how the firm s rules resources and relationships distribute various issues answers and decision makers into specific communications and procedures the paper develops these theoretical principles into a model of firm behavior and presents its implications for explaining firm behavior and adaptation 1997 by john wiley sons ltd

the backward incidence of pollution control a dual approach abstract the backward incidence of pollution control is reexamined using the techniques of duality theory the simple geometry used establishes the results and clarifies them without the complicated mathematical manipulations required in earlier works thereby making the material more attractive for classroom presentation

trade and factor movements with three factors and two goods abstract with three factors and two goods there are two extreme and one middle factor regardless of technical complementaries in the individual production functions the extreme factors must be enemies and the middle factor the other factor s friend with constant product prices

backward incidence of pollution damage compensation policy abstract the backward incidence of higher rates of compensation paid for damage on a factor of production is examined in a two sector three factor model with a linear pollution damage function on labour endowment the results implied by the stolper samuelson theorem are obtained with a consequent decrease in pollution and national income provided that the polluting and nonpolluting sectors are respectively intense in capital and labour and the complement relation between pollution and labour are assumed a geometric interpretation of the results is also provided

asset stock accumulation and sustainability of competitive advantage given incomplete factor markets appropriate time paths of flow variables must be chosen to build required stocks of assets that is critical resources are accumulated rather than acquired in strategic factor markets barney barney j 1986 strategic factor markets expectations luck and business strategy management sci october 1231 1241 sustainability of a firm s asset position hinges on how easily assets can be substituted or imitated imitability is linked to the characteristics of the asset accumulation process time compression diseconomies asset mass efficiencies inter connectedness asset erosion and causal ambiguity

factor price convergence in the late nineteenth century the authors examine a dramatic historical episode of factor price convergence in the late nineteenth century their focus is convergence between old world and new and the analysis centers on land and labor wage rental ratios boomed in the old world and collapsed in the new moving the resource rich labor scarce new world closer to the resource scarce labor abundant old world the authors use econometrics and simulations to identify proconvergence forces which include commodity price convergence factor accumulation and factor saving biases the results confirm that open economy characteristics and international market integration are important sources of convergence copyright 1996 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

the efficiency paradox bureaucratic and organizational barriers to profitable energy saving investments abstract the paradox of why profitable energy saving investments are not undertaken continues to provoke debate the underlying phenomenon might be called the efficiency paradox because it represents a case in which business firms which are often presumed or taken axiomatically to be economically efficient make decisions that do not maximize profits new data from one of the us environmental protection agency s voluntary pollution prevention programs enables this paradox to be explored statistically the data show that both the level and variation in returns to lighting upgrade investments cannot be explained by standard economic models substantial gains in energy efficiency can be achieved without sacrificing profitability both economic and organizational factors account for some of the variation in observed returns to these investments but the results suggest a need for improved and more comprehensive theories of the investment behavior of firms and other organizations

the resource based theory of the firm interest in the resource based view of the firm continues to grow in the field of business policy and strategy recently most of this interest seems to have been focused on understanding the empirical implications of this theory and especially on how a firm s resources and capabilities can affect its performance evaluating the empirical implications of the resource based view is of course a worthwhile endeavor we present an overview of contributions in this issue

income inequality and international migration the purpose of this paper is to analyse the impact of international factor movements on the personal distribution of income in order to get clearcut results we use a simple model of trade and migration in which there are two traded goods and three factors for any given country one of the traded goods corresponds to exports and the other to imports the three factors include capital and two types of labour skilled and unskilled we focus mainly on the alternative results of international migration of the two types of labour the geographical focus is worldwide excerpt

tightening environmental standards the benefit cost or the no cost paradigm ms ff ichael porter and claas van der linde have written a paper that is interesting and to us at least somewhat astonishing it is a defense of environmental regulation indeed an invitation to more stringent regulation that makes essentially no reference to the social benefits of such regulation this approach contrasts starkly with the methods that economists and other policy analysts have traditionally used when assessing environmental or other regulatory programs the traditional approach consists of comparing the beneficial effects of regulation with the costs that must be borne to secure these benefits for environmental regulation the social benefits include the reductions in morbidity or premature mortality that can accompany cleaner air the enhanced recreational opportunities that can result from water quality improvements the increased land values that might attend the cleanup of a hazardous waste site the enhanced vitality of aquatic ecosystems that might follow reductions in agricultural pesticide use or any of the other potentially significant benefits associated with tighter standards from this benefit cost approach emerges the standard tradeoff discussed in virtually every economics textbook porter and van der linde deny the validity of this approach to the analysis of environmental regulation claiming it to be an artifact of what they see as a static mindset in their view economists have failed to appreciate the capacity of

toward a new conception of the environment competitiveness relationship accepting a fixed trade off between environmental regulation and competitiveness unnecessarily raises costs and slows down environmental progress studies finding high environmental compliance costs have traditionally focused on static cost impacts ignoring any offsetting productivity benefits from innovation they typically overestimated compliance costs neglected innovation offsets and disregarded the affected industry s initial competitiveness rather than simply adding to cost properly crafted environmental standards can trigger innovation offsets allowing companies to improve their resource productivity shifting the debate from pollution control to pollution prevention was a step forward it is now necessary to make the next step and focus on resource productivity

the pricing of public intermediate goods revisited abstract this paper revisits the pricing of publicly produced goods for competitive downstream industries we show that under a general equilibrium setting and with a general technology in the private production a uniform pricing formula should apply to the household and the private firm this uniform pricing formula extends the optimal formulae derived in baumol and bradford 1970 in a straightforward way

international labor flows and national wages when income levels of some group in the economy fall behind those of others the blame frequently is cast on the nature of international trading relationships such has been the case recently in the united states with the struggle to maintain real wages for relatively lessskilled workers much of the debate has asked how changes in world prices or in technology at home or abroad have altered wage rates see e g susan collins 1996 jones and engerman 1996 in this note we focus on another potential culprit immigration and probe more widely into past historical experience in the united states and other countries when inflows of labor from abroad disturb wage rates for nationals such international labor flows could serve to enhance rather than to depress the earnings of the country s own laborers if the question addressed concerns the effects of immigration on the welfare of the original inhabitants of a country a disarmingly simple answer was provided some years ago by harry johnson 1967 as long as immigrants bring an accumulated bundle of labor and physical or human capital that is different from that possessed by local residents the latter must gain from immigration this is the basic gains from trade argument appropriate only if the country originally did not engage in any other form of trade and if all residents held balanced portfolios of capital and labor as well it ignores the social costs incurred and extra taxes collected when migrants flow into a country in this note we focus not on aggregate welfare effects but on the effect of immigration on the return to some homogeneous national group of laborers this question is the one that most sharply divides the views of labor economists from those of trade economists on the one hand increases in the supply of labor would seem naturally to depress the return to labor but in the basic heckscher ohlin trade model with two factors and two produced commodities an inflow of labor can be absorbed with absolutely no change in wage rates as long as the terms of trade remain undisturbed we begin by asking what some basic theoretical models tell us about this issue before turning to the historical record simple theory reveals that there are two basic attributes of immigration that affect income distribution relatively how substitutable immigrant labor is for the national labor force and the occupations in which immigrants are allowed to work

factor trade and goods trade world equilibria with trade in both goods and some factors are studied when international factor endowment differences are the cause of trade a generalized heckscher ohlin theorem is presented the goods trade patterns with and without factor trade are compared factor trade and goods trade tend to be substitutes complements if traded and non traded factors are cooperative non cooperative

factor intensities and factor substitution in general equilibrium abstract this article examines how factor intensity rankings between industries and the economy wide asymmetry in the degree of factor substitution combine to influence the manner in which changes in relative commodity prices affect the factoral distribution of income the reciprocal influence of factor endowment changes on the composition of outputs is also discussed the analysis is undertaken in a general three factor two commodity framework the minimal sized model that allows both influences to affect factor prices and admits of the possibility of complementarity between factors factors which are good substitutes find their returns behave somewhat similarly when commodity prices change while factors which are complements experience strongly asymmetrical fortunes a crucial role is played by a comparison of the share of the middle factor in each sector

investment in energy efficiency do the characteristics of firms matter the literature on energy efficiency provides numerous examples of apparently profitable technologies that are not universally adopted yet according to the standard neoclassical theory of investment profit maximizing firms should undertake all investments with a positive net present value the standard theory also holds that the discount rate for computing the present value of a project should be the return available on other projects in the same risk class and therefore should not depend on characteristics of the firm this model as applied to energy saving investments is tested by examining whether firms characteristics influence their decision to join the environmental protection agency s voluntary green lights program a discrete choice regression is estimated over a large sample of participating and nonparticipating firms missing values in the data matrix are replaced with multiple imputations from a distribution estimated using the expectation maximization algorithm the results show that 1 sub

barriers within firms to energy efficient investments abstract many investments in energy efficiency fail to be made despite their apparent profitability internal hurdle rates are often set at levels higher than the cost of capital to the firm reasons for these practices include bounded rationality principal agent problems and moral hazard the policy implication is that government can simultaneously improve overall energy efficiency and increase private sector productivity by providing informational and organizational services that go beyond the traditional regulatory framework

sustainable energy systems and company performance does the implementation of sustainable energy systems improve companies financial performance abstract the main aim of this paper is to analyse whether the adoption of sustainable energy systems improves corporate financial performance to this end we obtained data from a sample of 574 multinational companies from 36 countries in the 2008 2013 period on this data we implement a dynamic system panel data method our findings show that the adoption of sustainable energy systems allows firms to improve their short term corporate financial performance while not leading them to reduce their corporate financial performance in the long term specifically our results indicate that an increase in energy efficiency and the use of renewable energy sources do not significantly affect corporate financial performance neither does the integration of energy efficiency systems and renewable energy sources have any significant influence on corporate financial performance while the level of implementation of sustainable energy management systems has a significant effect on short term but not long term corporate financial performance furthermore other control variables such as research and development expenditure and year are also relevant in explaining firms financial performance the adoption of sustainable energy systems helps to improve corporate financial performance in the short term but has no affect in the long term this might be because the monitoring of energy efficiency using key performance indicators allows firms to detect and correct failures in the production process and hence improve short term financial performance however this measure does not generate competitive advantages for firms and therefore has no effect on long term corporate financial performance from a scientific perspective of energy this paper contributes to the literature by providing a detailed explanation of how the adoption of sustainable energy systems proposed by peura 2013 influences corporate financial performance on the basis of new empirical evidence these explanations provide a strong rationale for improving the efficient use of energy and harvesting low hanging fruits in the short term from a managerial perspective policymakers should encourage firms to align sustainable energy systems with their core business strategy by developing green technologies that allow them to acquire rare and valuable capabilities and abilities which generate competitive advantage and therefore allow firms to increase their long term corporate financial performance

free trade and income redistribution in a three factor model of the u s economy the move toward free trade promises to alter the distribution of income in the u s labor groups generally do not favor the move toward free trade which can be characterized by the continuing decline in the price of manufactured goods relative to business services the present study predicts that unskilled labor in the u s will lose under a program of free trade using a general equilibrium model of production factor shares industry shares and estimates of substitution for skilled labor unskilled labor and capital are used to examine comparative statics the interplay of factor intensity and factor substitution in the three factor production structure has proven a considerable analytical challenge building on the textbook production model with two factors the third productive factor allows technical complementarity and creates a more complex pattern of factor intensity both factor intensity and factor substitution affect the qualitative nature of the comparative statics little is known about the model s quantitative properties a 3 x 3 model with outputs of the three major sectors agriculture manufacturing services is specified and a 3 x 2 model without agriculture is also examined factor substitution is estimated with production function across states skilled labor separated by various census categories cannot be aggregated with unskilled labor in any sector and constant returns to scale cannot be rejected as a null hypothesis additionally the three inputs capital labor skilled labor are all technical substitutes comparative static results follow a pattern suggested by factor intensity changing prices of goods generally have elastic effects on factor prices stolper samuelson results in other words have a quantitative weight price changes due to a program of free trade will significantly affect income distribution similarly rybczynski type results are quantitatively significant in that factor endowment changes have elastic effects on outputs the implication is that output patterns will differ significantly across freely trading partners elasticities of factor prices with respect to endowment changes on the other hand are very inelastic this inelasticity suggests that there would only be small long run effects of international migration capital flows or endowment differences on the international pattern of factor income this inelasticity is called near factor price equalization nfpe under nfpe freely trading countries will experience a vector of factor prices nearly equal to each other nfpe suggests that the qualitative effects of changing or different factor endowments

second best pricing with upstream distortions abstract optimal pricing by a public firm facing an upstream monopolist and monopsonist is compared with the first best rule itself a modified ramsey formula deviations from marginal cost are larger and occur even in the absence of a budget constraint

strategy complexity and economic rent this paper discusses important friction forces that future theories of strategy must incorporate some of these are technological and environmental but the most important ones it is argued are psychological the view is developed that strategy at its core concerns the development and testing of heuristics for high stake decisions in environments too unstable and complex to be optimized the paper especially highlights the behavioral dimension in the belief that strategies should incorporate both the rational and suboptimal aspects of human behavior the rational approach is in many ways the easier as there may be only one way to be right yet the great variety in which people and companies can err gives strategy its creative and real world challenge the tension between the rational and behavioral components is what the field of strategy should seek to exploit

international trade with a public intermediate good abstract the purpose of this paper is to investigate familiar trade theorems such as the stolper samuelson samuelson rybczynski heckscher ohlin and factor price equalization theorems when a public intermediate good is accommodated in the 2 2 general equilibrium trade model the public good which is introduced by the lindahl pricing rule is assumed to be of a semipublic kind then we present the circumstances where the positive results for all of the above theorems except the factor price equalization theorem hold as for factor price equalization we show that there is a tendency for trade to equalize prices

organizational capabilities and the economic history of the industrial enterprise in my book scale and scope 1990 i focused on the history of the modern industrial firm from the 1880s when such firms first appeared through world war ii i did so by comparing the fortunes of more than 600 enterprises the 200 largest industrial firms at three points in time world war i 1929 and world war ii in each of the three major industrial economies those of the united states britain and germany in this paper i first describe the similarities in the historical beginnings and continuing evolution of these enterprises and then outline my explanation for these similarities next i relate my explanation of these empirical regularities to four major economic theories relating to the firm the neoclassical the principal agent the transaction cost and the evolutionary finally i suggest the value of the transactions cost and evolutionary theories to historians and economists who are attempting to explain the beginnings and growth of modern industrial enterprises

a theorem on income distribution in a small open economy abstract if the number of productive factors exceeds the number of commodities produced changes in factor endowments and or any commodity price will alter factor prices in a way that depends both upon factor intensities and the degree of factor substitutability however bilateral factor intensity rankings for constant price industries by themselves restrict possible factor price changes if factors are ranked from most to least intensive in any such pair of industries all the gainers cannot be located at one end of the ranking

second best pricing of publicly produced inputs the case of downstream imperfect competition abstract efficient second best pricing is examined for a public enterprise facing two distortions a profit constraint and imperfect competition among some customer industries we suggest a measure of downstream industry distortion for the purpose of efficient pricing the pricing rule contains two opposing elements the shadow value of public profit and this measure of the downstream distortion whose sum determines whether the efficient second best input price is above or below marginal cost efficient pricing normally implies relative subsidization of imperfectly competitive downstream firms

unemployment and trade liberalisation in contrast to the focus of the public debate over trade liberalisation on job losses there is a widespread view among economists that unemployment and trade issues should be considered separately this view cannot be justified theoretically and ignores the growing number of general equilibrium trade models with unemployment in a simple model with an exogenous wage floor trade liberalisation can lead to either gains or losses depending on the production technology severity of the factor market distortion factor intensities of the industries and conditions in trading partners definite results can be derived about gains from liberalising trade with lower wage floors about relative abundance of the unemployed factor dampening losses when trade is liberalised and about gains when the good which uses the unemployed factor is exported the theoretical models are then linked to the policy modelling literature using the example of recent australian controversies over liberalisation of trade in automobiles and textiles it is argued that trade liberalisation would be better advanced by including endogenous employment in trade policy simulation exercises and by discussing employment effects rather than brushing them aside as temporary adjustment problems or regional difficulties

international factor movements and the ramaswami argument in a succinct but classic article appearing in economica in 1968 ramaswami put forth an argument supporting the superiority of a policy that attracts foreign factors over a policy that allows a relatively abundant factor to emigrate in each case the active home country is assumed to levy taxes on factor flows so as to capture for itself the discrepancy in return to the same factor at home and abroad the asymmetry reflected by this policy ranking rests on a basic propeity of production functions the convexity of technology plus the ability of the active home country to hire or rent out factors at wages or rentals prevailing in the foreign country briefly put the ramaswami argument proceeds as follows suppose the active home country is capital abundant and has levied on optimal tax on earnings of its own capital operating abroad now consider repatriating this capital and allowing for the first time some inflow of foreign labour in particular suppose the home country allows a level of immigration identical to the labour force previously employed with the home capital that is being repatriated such a transfer of home capital and foreign labour out of the foreign country leaves factor proportions abroad undisturbed and thus does not alter the wage that must be paid to attract the requisite bundle of foreign workers although the home country thus avoids any increase in factor costs in foreign markets it can increase output since the capital labour ratiooriginally employed at home at high home wage rates is greater than the ratio in the freshly acquired bundle from abroad by adopting a uniform capital labour ratio over all factors now employed at home output and thus real income rises there may be even further gains to be had by allowing yet a different optimal level of immigration in the home country which has now banned capital exports 2 essential to the ramaswami argument is the ability of the home country to extract a bundle of factors previously employed abroad without disturbing factor prices in that country indeed jones coelho and easton 1983 have suggested that in the context of the ramaswami discussion the original argument could be pursued to suggest that the home country gains not only from repatriating its own capital but from actually encouraging foreign capital to be employed at home such a capital flow is admittedly uphill the home country would have to pay out more in rentals than such capital can earn at home despite this fact such an import of capital and labour in the same proportions found abroad does not alter foreign factor prices but does via the same ramaswami type argument on the convexity of the technology result in gains at home although ramaswami s own discussion starts with a repatriation of home capital previously invested abroad his argument can be applied directly to the foreign autarky factor endowment bundle if technology exhibits constant returns to scale and if all both factors are indeed internationally

free trade and factor price polarization abstract factor price equalization between trading partners is perhaps the best known implication of the heckscher ohlin samuelson model of production and trade it has long been known that with more primary factors than goods this result is not necessary recent studies have investigated effects of changing prices on factor payments in the three factor two good trade model this short note emphasizes that when such an economy moves from autarky to free trade payment to a relatively cheap factor may fall polarizing factor prices conditions favoring this outcome are examined

efficiency gains within firms under voluntary environmental initiatives this paper focuses on efficiency gains that voluntary environmental initiatives may achieve within the firm current debate concerning the extent and significance of inefficiencies within firms is critically important to the progress of energy and environmental policies several recent lines of inquiry in microeconomics help explain the persistence of inefficiencies within firms in addition two of the most prominent new approaches in the field of business strategy resource based strategy and the capabilities perspective focus on the heterogeneity among firms and the resulting pockets of inefficiency within firms they suggest at least three generic strategies for voluntary environmental initiatives challenging outdated organizational routines creating opportunities for differentiation or complementing firms resource investment trajectories these generic approaches suggest that there is considerable scope for further experimentation with voluntary environmental initiatives

recent evolutionary theorizing about economic change this famous passage from marshall s principles of economics it first appeared in the fifth edition which came out in 1907 nicely brings out two issues which are as germane to economics today as they were when marshall wrote the first is the heavy reliance by economists in their formal theorizing on the notion of equilibrium the other is the appeal that biological conceptions3x201d have for many economists particularly when their focus is on economic change

factor movements with three factors and two goods in the u s economy abstract ruffin s 1981 theoretical finding that extreme factors must be enemies and the middle factor must be a friend of both extreme factors with constant product prices in a three factor two good general equilibrium model is confirmed empirically for the united states results are used to explain the positions factor owners take on issues of factor movement policies

industrial shut downs and medium run factor intensity reversals while short run factor intensity reversals lead to industrial shut downs when there are two productive factors this paper shows that an industry can undo an intensity reversal over the medium run and avoid shutting down when there are three or more factors medium run adjustment begins with a capital fixed input and extends until it has become perfectly mobile j peter neary 1978 develops a picture of adjustment with two industries and two inputs where an industry must shut down following an intensity reversal the present study adds a third input skilled labor or natural resources to capital and labor

do tariffs protect specific factors it is shown that a tariff can lower payment to a productive factor used only in specific to the protected industry in a simple production model this may occur anytime the protected sector shares more than one common factor with the rest of the economy as seems most likely intuition based on the well known specific factors model where sectors share a single common factor should be modified whether specific factors effectively receive protection from tariffs becomes an empirical issue

the energy efficiency gap what does it mean abstract as renewed attention has been given by policy makers to energy conservation issues it has frequently been asserted that an energy efficiency gap exists between actual and optimal energy use the critical questions is how to define the optimal level of energy efficiency this paper seeks to disentangle some confusing strands of argument that are frequently brought to bear on this question by identifying the major conceptual issues that determine the set of feasible answers we identify five separate and distinct notions of optimality the economists economic potential the technologists economic potential hypothetical potential the narrow social optimum and the true social optimum each of these has associated with it a corresponding definition of the energy efficiency gap our analysis demonstrates that necessary preconditions for identifying the right measure of the energy efficiency gap include understanding and disentangling market failure and non market failure explanations for the gradual diffusion of energy efficient technologies

ownership structure institutional organization and measured x efficiency efficiency measurement has become a very popular field in applied economics in recent years and with this interest there has been a large intellectual investment in refining the empirical methods available to researchers in the area in this paper we relate these developments to harvey leibenstein s original 1966 insight into the psychological ideas underlying the notion that economic agents may not achieve maximal efficiency in their productive decisions and behavior of course it is always possible to argue that apparent inefficiency only arises from a failure of the observer to realize what it is that is being maximized however we shall evade this easy escape route into nonfalsifiable hypothesizing and instead shall take at face value the fact that too many empirical studies have come up with substantial measures of inefficiency for us to ignore its importance for normative economics

complementarity in a simple general equilibrium production model a simple three factor two good general equilibrium model allowing complementarity in production is examined conclusions of general equilibrium economics with two factors must be reinterpreted and qualified when complementarity is possible sign patterns of how changing factor endowments affect outputs and how changing prices affect factor payments are uncovered for a small open economy results should prove valuable to a wide range of economists interested in extending general equilibrium analysis to include complementary factors of production

voluntary environmental agreements good or bad news for environmental protection abstract there has been growing interest in the use of voluntary agreements vas as an environmental policy tool this article uses a simple model to determine whether vas are likely to lead to efficient environmental protection we consider cases where polluters are induced to participate either by a background threat of mandatory controls the stick approach or by cost sharing subsidies the carrot approach the results suggest that the overall impact on environmental quality could be positive or negative depending on a number of factors including the allocation of bargaining power the magnitude of the background threat and the social cost of funds
