dynamics of output and employment in the u s economy this paper investigates the changing relationship between employment and real output in the u s economy from 1948 to 2010 both at the aggregate level and at some major industry grouping levels of disaggregation real output is conventionally measured as value added corrected for price ination but there are some industries in which no independent measure of value added is possible and existing statistics depend on imputing value added to equal income indexes of output that exclude these imputations are closely correlated with employment over the whole period and remain more closely correlated during the current business cycle this analysis oers insights into deeper

the inverted pyramid a neo ricardian view on the economy environment relationship abstract in ecological economics natural resources which may contribute only a small amount to gdp are viewed as fundamental to the functioning of the economy they are sometimes pictured as sitting at the base of an inverted pyramid with the rest of the economy balanced on top of them in this paper we show that when prices are set by markup a standard heterodox assumption then the inverted pyramid picture of the economy emerges naturally in a neo ricardian model we demonstrate the use of the model with brief applications to biophysical economics the paper is one of a growing number that use heterodox macroeconomics to address questions in ecological economics

the role of multilateral institutions in international trade cooperation the world trade organization wfo lacks the power to directly enforce agreements it is therefore important to understand what role the wto can play to facilitate international cooperation and whether a multilateral institution can offer distinct advantages over a web of bilateral agreements this paper examines two potential benefits of a multilateral trade institution first verifying violations of the agreements and informing third parties thus facilitating multilateral reputation mechanisms second promoting multilateral trade negotiations rather than a web of bilateral negotiations the model suggests that a multilateral approach is particularly important when there are strong imbalances in bilateral trading relationships

labour s shares and profitability crisis in the u s recent experience and post war trends extends work on u s rate of profit by t e weisskopf 1979 firstly the author finds by extending weisskopf s data into the early 1980s that continued downward pressure on profitability i s explained by capacity utilization in contrast to weisskopf s explanation of rising labor share secondly it is found that ri sing labor share in the post war period is largely composed of r ising levels of supplemental fringe benefits and is in the earl y part of the period also explained by rising nonproduction lab or costs production worker wage share falls secularly and this may be explained particularly in the 1960s by rising price mar k ups on direct cost copyright 1987 by oxford university press

from agriculture to rurality new approaches in territorial economics in the first part the paper presents the evolution of the rural develoment theories from 50s to nowadays consequently in the second part it is addressed the issue of how the transition from subsistance economy to traditional economy to agricultural economy to rural economy could delineate virtuous processes of local development in specific contexts this concept is futher developed in the third part where territorial development is analysed in accordance with international studies and more specifically with european ones and in the forth where the topic is critically focused in the framework of the brazilean literature

approximate surrogate production functions the cambridge debate showed that an aggregation of capital is not possible in general a recent investigation has found one example for reswitching and several for reverse capital deepening but the paradoxes appear to be infrequent the paper provides a theoretical justification of this result and shows how wage curves of input output matrices with small non dominant eigenvalues become quasi linear with some numeraires large random systems lead to the genesis of such states approximate surrogate production functions then seem possible a family of economic systems with constant capital composition allows construction of a surrogate production function copyright oxford university press

the 40 neoclassical aggregate theory of production the assumption that production in an economic system may be described by an aggregate neoclassical production function is at the heart of most modern equilibrium neoclassical business cycles and growth models its validity requires stringent assumptions on individual production functions and market structure in this article the likelihood that an aggregate neoclassical production function could emerge from a simple heterogeneous production system is assessed by the use of computer simulations the conclusion is that there exists a world of significant size for which the aggregate neoclassical theory of production does not hold

a statistical equilibrium model of competitive firms abstract we find that the empirical density of firm profit rates measured as returns on assets is markedly non gaussian and reasonably well described by an exponential power or subbotin distribution we start from a statistical equilibrium model that leads to a stationary subbotin density in the presence of complex interactions among competitive heterogeneous firms to investigate the dynamics of firm profitability we construct a diffusion process that has the subbotin distribution as its stationary probability density this leads to a phenomenologically inspired interpretation of variations in the shape parameter of the subbotin distribution which essentially measures the competitive pressure in and across industries our findings have profound implications both for the previous literature on the persistence of profits as well as for understanding competition as a dynamic process our main formal finding is that firms idiosyncratic efforts and the tendency for competition to equalize profit rates are two sides of the same coin and that a ratio of these two effects ultimately determines the dispersion of the equilibrium distribution

are green hopes too rosy employment and welfare impacts of renewable energy promotion in view of pressing unemployment problems policy makers across all parties jump on the prospects of renewable energy promotion as a job creation engine which can boost economic well being our analytical model shows that initial labor market rigidities in theory provide some scope for such a double dividend however the practical outcome of renewable energy promotion might be sobering our computable general equilibrium analysis of subsidized electricity production from renewable energy sources res e in germany suggests that the prospects for employment and welfare gains are quite limited and hinge crucially on the level of the subsidy rate and the financing mechanism if res e subsidies are financed by labor taxes welfare and employment effects are strictly negative for a broad range of subsidy rates the use of an electricity tax to fund res e subsidies generates minor benefits for small subsidy rates but these benefits quickly turn into significant losses as the subsidy rate exceeds some threshold value

family structure institutions and growth the origins and implications of western corporations siders the importance of the family as an institution little attention however has been given to the impact of the family structure and its dynamics on institutions this limits our ability to understand distinct institutional developments and hence growth in the past and present this paper supports this argument by highlighting the importance of the european family structure in one of the most fundamental institutional changes in history and reflects on its growth related implications what constituted this change was the emergence of the economic and political corporations in late medieval europe corporations are defined as consistent with their historical meaning intentionally created voluntary interest based and self governed permanent associations guilds fraternities universities communes and city states are some of the corporations that have historically dominated europe businesses and professional associations business corporations universities consumer groups counties republics and democracies are examples of corporations in modern societies the provision of corporation based institutions to mitigate problems of cooperation and conflict constituted a break from the ways in which institutions had been provided in the past historically large kinship groups such as clans lineages and tribes often secured the

an empirical investigation of paradoxes reswitching and reverse capital deepening in capital theory this paper examines the empirical relevance of the capital controversy the price model of sraffa and the dual models of the price and quantity systems of von neumann become the basis of the investigation in the course of the controversy it proved easy to construct theoretical examples which contradicted the fundamental neoclassical hypothesis of an inverse capital demand function this paper presents empirical examples for the first time thiry two input output tables from the oecd database serve as data as a result one envelope is found which involves reswitching reverse substitution of labour or reverse capital deepening are observed in about 3 65 of tested cases they involve at least two switchpoints copyright 2006 oxford university press

impact of energy efficiency gains on output and energy use with cobb douglas production function abstract a special issue of energy policy 28 2000 was devoted to a collection of papers edited by dr lee schipper the collection included a paper entitled a view from the macro side rebound backfire and khazzoom brookes in which it was argued that the impact of fuel efficiency gains on output roughly gdp is likely to be relatively small by cobb douglas production function however an error in the analysis leads to under estimation of the long term impact this paper first provides a partial equilibrium analysis by an alternative method for the same case and then proceeds to an analysis on the issue in a two sector general equilibrium system in the latter analysis energy price is internalized both energy use efficiency and energy production efficiency are involved

the fund flow approach a critical survey the fund ow approach to production theory was proposed by nicholas georgescu roegen almost half a century ago and it provides a description of production as a process unfolding in time and entailing a temporal coordination between dierent elements despite the initial interest the approach has seldom received attention by mainstream economists and it is not yet well known the paper critically surveys georgescu roegen s model together with i the later developments and modications ii the recent criticisms focused on its limitations due to the instrumental assumption of constant eciency for funds the paper concludes by discussing the limits and comparative merits and suggesting possible applications

medieval universities legal institutions and the commercial revolution we present new data documenting medieval europe s commercial revolution using information on the establishment of markets in germany we use these data to test whether medieval universities played a causal role in expanding economic activity examining the foundation of germany s first universities after 1386 following the papal schism we find that the trend rate of market establishment breaks upward in 1386 and that this break is greatest where the distance to a university shrank most there is no differential pre 1386 trend associated with the reduction in distance to a university and there is no break in trend in 1386 where university proximity did not change these results are robust to estimating a variety of specifications that address concerns about the endogeneity of university location universities provided training in newly rediscovered roman and canon law students with legal training served in positions that reduced the uncertainty of trade in the middle ages we argue that training in the law and the consequent development of legal and administrative institutions was an important channel linking universities and greater economic activity in medieval germany

the aggregate production function is not neoclassical standard postulates concerning the aggregate production function are about marginal productivities and the associated demands for labour and capital these demands are supposed to be negatively related to the factor prices namely the wage rate and the interest rate the theoretical cases in which these neoclassical properties fail to hold are regarded as anomalies we compute the aggregate values for production capital and labour and find that the neoclassical postulates do not hold for the detailed dataset that we consider the obvious implication of this result is that the models and analysis based on the aggregate neoclassical production functions are ill founded as they are based on something that does not exist

technology distribution and the rate of profit in the us economy understanding the current crisis this paper offers a synoptic account of the state of the debate among marxist scholars regarding the current structural crisis of capitalism identifies two broad streams within the literature dealing in turn with aggregate demand and profitability problems and proceeds to concentrate on an analysis of issues surrounding the profitability problem in two steps first evidence on profitability trends for the non farm non financial corporate business the non financial corporate business and the corporate business sectors in post war usa are summarised a broad range of profit rate measures are covered and data from both the us bureau of economic analysis nipa and fixed assets tables and the federal reserve flow of funds account are used second the underlying drivers of profitability in terms of technology and distribution are investigated the profitability analysis is used to offer some hypotheses about the current structural crisis copyright oxford university press

central banks at war war is expensive troops must be equipped and weapons must be procured when the enormous borrowing requirements of war make the sovereigns credibility problem more difficult central banks enhance a government s ability to borrow by being the sole direct purchaser of government debt the central bank increases the effective punishment that can be imposed on the government for defaulting on the marginal lender this increases lenders confidence that the government will be punished in case of default making lenders willing to purchase the debt at a lower rate of interest the sovereign dependent on the low borrowing costs offered by the central bank has an incentive to retain the bank data covering the nineteenth and early twentieth centuries reveal that possessing a central bank lowers the sovereign s borrowing costs particularly during times of war

cultural and institutional bifurcation china and europe compared how to sustain cooperation is a key challenge for any society different social organizations have evolved in the course of history to cope with this challenge by relying on different combinations of external formal and informal enforcement institutions and intrinsic motivation some societies rely more on informal enforcement and moral obligations within their constituting groups others rely more on formal enforcement and general moral obligations towards society at large how do culture and institutions interact in generating different evolutionary trajectories of societal organizations do contemporary attitudes institutions and behavior reflect distinct pre modern trajectories this paper addresses these questions by examining the bifurcation in the societal organizations of pre modern china and europe it focuses on their distinct epitomizing social structures the clan and the city that sustain cooperation through different mixes of enforcement and intrinsic motivation the chinese clan is a kinship based hierarchical organization in which strong moral ties and reputation among clan members are particularly important in sustaining cooperation in medieval europe by contrast the main example of a cooperative organization is the city here cooperation is across kinship lines and external enforcement plays a bigger role but morality and reputation

on measuring the wealth of nations the us economy 1964 2001 this paper examines the methodology of shaikh and tonak measuring the wealth of nations 1994 underlying their calculation of estimates of productive labour in the us economy from 1964 to 2001 the focus is not on the results but on the methods that generate them the paper finds that the compromises made by shaikh and tonak because of data unavailability are unreliable and that better approximations are possible on this latter basis the shaikh and tonak methodology can be used to provide the labour and wage estimates needed for empirical investigations in the surplus based tradition copyright 2005 oxford university press

technology and distribution historical trajectories a la marx abstract in capital marx introduces a system of historical tendencies accounting for the trends of the major technological and distributional variables notably the profit rate quite distinct from the usual steady states marx s main insight is that of a difficulty to innovate it is difficult to find new processes allowing for the growth of labor productivity while not considerably reducing the productivity of capital the growth of the wage rate is stimulated by the rise of employment but the stabilization of the share of wages forbids a direct imputation of the decline of the profit rate to the excessive growth of the wage rate

negative rebound and disinvestment effects in response to an improvement in energy efficiency in the uk economy this paper uses a computable general equilibrium cge framework to investigate the conditions under which rebound effects may occur in response to increases in energy efficiency in the uk national economy previous work for the uk has suggested that rebound effects will occur even where key elasticities of substitution in production are set close to zero the research reported in this paper involves carrying out a systematic sensitivity analysis where relative price sensitivity is gradually introduced into the system focusing specifically on elasticities of substitution in production and trade parameters in order to determine conditions under which rebound effects become a likely outcome the main result is that while there is positive pressure for rebound effects even where direct and indirect demands for energy are very price inelastic this may be partially or wholly offset by negative income competitiveness and disinvestment effects which also occur in response to falling energy prices the occurrence of disinvestment effects is of particular interest these occur where falling energy prices reduce profitability in domestic energy supply sectors leading to a contraction in capital stock in these sectors which may in turn lead to rebound effects that are smaller in the long run than in the short run a result that runs contrary to the predictions of previous theoretical work in this area

a note on the organic composition of capital and profit rates it is widely believed that the rate of profit across industrial sectors while not in fact uniform as stipulated in the theory of prices of production is independent of the sectoral organic composition of capital it follows that the simple labour theory of value must be systematically in error as a predictor of actual sectoral aggregate prices we offer empirical evidence from the us economy 1987 input output table suggesting that this is not soc there is a substantial and statistically significant negative association between organic composition and profit rate across sectors copyright 2003 oxford university press

competition and the incentive to produce high quality previous literature indicates that when quality is a choice variable firms have an incentive to produce high quality to maintain their reputations with consumers the strategic interaction among firms and competition for market share is not considered this paper finds that when firms compete for market share perfect equilibria in which firms produce high quality goods need not exist competition for customers can eliminate the price premium needed to induce firms to maintain a reputation for high quality production in this case economists and policy analysts should pay greater attention to the interaction among firms and the institutions such as professional associations that structure interfirm relations when considering whether firms have an incentive to produce high quality goods

growing up in a recession does the historical macroeconomic environment affect preferences for redistribution we find that individuals who experienced a recession when young believe that success in life depends more on luck than effort support more government redistribution and tend to vote for left wing parties the effect of recessions on beliefs is long lasting we support our findings with evidence from three different datasets first we identify the effect of recessions on beliefs exploiting time and regional variation in macroeconomic conditions using data from the 1972 2010 general social survey our specifications control for nonlinear time period life cycle and cohort effects as well as a host of background variables second we rely on data from the national longitudinal survey of the high school class of 1972 to corroborate the age period cohort specification and look at heterogeneous effects of experiencing a recession during early adulthood third using data from the world value survey we confirm our findings with a sample of 37 countries whose citizens experienced macroeconomic disasters at different points in history

enforcement of implicit employment contracts through unionization in a world in which employment contracts are incomplete it is costly for a firm to establish credibility for honoring implicit terms of employment agreements by monitoring the employment relationships between the firm and its workers the labor union may provide the workforce with valuable information regarding the firm s adherence to these implicit agreements thus the union provides a signaling mechanism that allows workers to coordinate their actions in order to discipline the firm for a breach of the implicit contract this mechanism enhances the firm s credibility when forming employment contracts and facilitates increased employment levels

wheat agriculture and family ties abstract several recent contributions to the literature have suggested that the strength of family ties is related to various economic and social outcomes for example alesina and giuliano 2014 highlight that the strength of family ties is strongly correlated with lower gdp and lower quality of institutions however the forces shaping family ties remain relatively unexplored in the literature this paper proposes and tests the hypothesis that the agricultural legacy of a country matters for shaping the strength of its family ties using data from the world values survey and the european values study the results show that societies with a legacy of cultivating wheat tend to have weaker family ties analysis at the sub national level us data and the country level corroborate these findings the estimations allow for alternative hypotheses which propose that pathogen stress and climatic variation can potentially also give rise to the formation of family ties the results suggest that the suitability of land for wheat production is the most influential factor in explaining the variation in the strength of family ties across societies and countries

fuel conserving and using production functions abstract this article compares eight production cost functions used or potentially useful for exploring how energy efficiency gains affect energy consumption we show the practitioner s choice of function can inadvertently pre determine results and make recommendations as to which functions are flexible enough to prevent this we also show pre selected factor substitution elasticities can similarly pre determine results to aid the comparison we decompose the energy consumption rebound effect into intensity and output income effects which also delivers insight into the mechanisms of rebound we conclude by recommending practitioners restrict themselves to either the gallant fourier or the generalized leontief symmetric generalized barnett cost functions as being sufficiently rebound flexible the translog cost function may be suitable given certain conditions and a particular form of the ces solow function is a possible but problematic candidate along the way the article provides a general methodology for similarly examining any arbitrarily defined constant returns to scale production or cost function

european economic integration and comparative advantages on the basis of a set of input output tables we computed the european net product possibility frontier nppf for the years from 1995 to 2011 during this period several barriers to trade have been removed allowing higher levels of trade and regional integration subsequently we propose a method to check whether the prediction to be derived from comparative advantages cas theory namely a specialization pattern that allows to reach the nppf is verified the results suggest that cas were not exploited well during the period considered and no positive trend emerged the implication of our results is that there is ample scope for a coordinated policy aimed at improving allocation of resources further research on this topic seems to be necessary

coordination commitment and enforcement the case of the merchant guild we interpret historical evidence in light of a repeated game model to conclude that merchant guilds emerged during the late medieval period to allow rulers of trade centers to commit to the security of alien merchants the merchant guild developed the theoretically required attributes secured merchants property rights and evolved in response to crises to extend the range of its effectiveness contributing to the expansion of trade during the late medieval period we elaborate on the relations between our theory and the monopoly theory of merchant guilds and contrast it with repeated game theories that provide no role for formal organization

value price and exploitation the logic of the transformation problem this paper tries to clarify the logical structure of the relationship between labor values and prices from an axiomatic perspective the famous transformation problem is interpreted as an impossibility result for a specific interpretation of value theory based on specific assumptions and definitions a comprehensive review of recent literature is provided which shows that there are various theoretically relevant and logically consistent alternative interpretations based on different assumptions and definitions

optimal cartel equilibria with imperfect monitoring abstract there exist optimal symmetric equilibria in the green porter model 4 8 having an elementary intertemporal structure such an equilibrium is described entirely by two subsets of price space and two quantities the only production levels used by firms in any contingency the central technique employed in the analysis is the reduction of the repeated game to a family of static games

an institution based view of executive compensation a multilevel meta analytic test we offer a multilevel meta analytic study of the firm performance executive compensation relationship comprising prior tests derived from 332 primary studies nested in 29 countries although our work modestly supports the optimal contracting theory based expectation that compensation is positively associated with performance it also reveals considerable cross country variability in this relationship we trace this variance to differences in the level of development of the formal and informal institutions protecting investors against managerial overcompensation and underperformance in terms of intentionally devised and enforced formal institutions we find significant positive moderating effects on the focal relationship of the rule of law and strength of investor protection variables for self enforcing informal institutions we find similar effects for concentrated ownership and compensation related entries in codes of good corporate governance we also find that formal and informal institutions function in a complementary manner in shaping the performance sensitivity of executive compensation the focal relationship becomes stronger when concentrated owners have access to well functioning courts and when informal norms of good governance are supported by shareholder protection laws our study thus suggests that optimal contracting theory must be supplemented with an institution based view to account for the conditioning effects of institutions on national contracting environments

exploring the logic behind southern africa s food crises summary government action during food crises in southern africa frequently exacerbates the problems driving food staple prices well beyond import parity we argue that an inability to make credible commitments due largely to a lack of trust between public and private sectors contributes to this dynamic empirical policy analysis can facilitate resolution only within a consultative process involving a broad range of stakeholders the policies emerging from such a process are not likely to approximate first best recommendations yet the precise policies may be less important than the fact that they exist and that main stakeholders find them credible

values prices of production and market prices some more evidence from the greek economy this paper extends the empirical investigation of the relation between labour values and different price forms in the case of the greek economy subjecting the labour theory of value to empirical tests with data from various countries helps in the derivation of general conclusions regarding its empirical validity and practical usefulness our results on the closeness of values and prices as measured by their absolute deviation and correlation the shape of the wage profit curves the predictive power of labour values over market prices compared with other value bases and the comparison of fundamental marxian categories when estimated in value and price terms provide further support for the empirical strength of the labour theory of value

sraffa leontief lange the political economy of input output economics abstract the fields of political economy and input output economics are commonly unrelated due to the discrepancy between the qualitative and quantitative analysis in economic science with the aim to overcome this separation this paper relates the basic model of production of commodities by means of commodities to the paradigm of planning as the substitute for the market by sketching the logical historical development of input output economics the model of sraffa the leontief matrices and the political economy of marxist tradition represented by oskar lange are strongly associated so that the typical qualitative concepts of planning law of value and historical development of the capitalist system can be connected to the quantitative framework of matrix programming and mathematical formalization

on measuring the deviation of prices from values it has often been found useful to measure in some way the extent to which with profit prices diverge from zero profit values but it is not satisfactory to employ a measure which varies with the choice of numeraire for this element of arbitrariness has nothing to do with the central idea of asking how much the direction of the price vector differs from that of the value vector the authors develop a measure which involves no numeraire and then illustrate its use with data from the united kingdom the irish republic and australia copyright 1998 by oxford university press

values prices and wage profit curves in the us economy this paper presents labor values and prices of production calculated for the postwar u s economy using a seventy one sector input output model with fixed capital as well as actual wage profit curves during the same period it is found that the cross sectional deviations of values and prices of production from market prices are quite small between 12 and 14 percent on average over time approximately 75 percent of the variation of market prices is accounted for by changes by both values and prices of production and 93 percent of the variation of prices of production is accounted for by changes in labor values wage profit curves exhibit near linearity casting some doubt on the significance of reswitching for actual economies copyright 1989 by oxford university press

the economics of exogamous marriage in small scale societies marriage is a core institution in almost every human society including small scale societies based on foraging or subsistence agriculture a crucial dimension of the marriage systems in such societies involves endogamy and exogamy that is the choice of a marriage partner from within one s own community or from an outside community we develop a model in which the exogamy rate is higher when good local matches are scarce due to small community sizes and when productivity differs across communities due to environmental shocks these theoretical predictions are supported by econometric analysis of data from the standard cross cultural sample jel d13 j11 n30 z13

development and the interaction of enforcement institutions we examine how formal and informal contract enforcing institutions interact in a competitive market with asymmetric information where consumers do not observe quality before purchase firm level incentives for producing high quality can be achieved with an informal enforcement mechanism reputation the efficacy of which is enhanced by consumers investing in connectedness or with a formal mechanism legal enforcement the effectiveness of which can be reduced by means of bribes we show that formal and informal enforcement mechanisms do not necessarily substitute each other while high levels of judicial efficiency decrease consumers incentives to connect higher consumers connectedness leads to higher levels of judicial efficiency we then look at how the equilibrium institutional mix evolves with the level of development in doing so we show the presence of a new physical channel that can affect institutions i e the frequency of bad productivity shocks that in less developed settings can impact on firms incentives to cheat c 2010 elsevier b v all rights reserved

labour time versus alternative value bases a research note this paper provides empirical support for the law of value understood as the proposition that embodied labor time is conserved in exchanges of commodities market prices are well correlated with the sum of direct and indirect labor content is it possible to produce equally good correlations by taking the sum of direct and indirect x content where x is some input other than labor time the authors repeat the analysis for electricity iron and steel and oil and show that the answer is no the high correlations in the case of labor time are therefore not a statistical artifact copyright 1997 by oxford university press

kinship cooperation and the evolution of moral systems across the social sciences a key question is how societies manage to enforce cooperative behavior in social dilemmas such as public goods provision or bilateral trade according to an influential body of theories in psychology anthropology and evolutionary biology the answer is that humans have evolved moral systems packages of functional psychological and biological mechanisms that regulate economic behavior including a belief in moralizing gods moral values negative reciprocity and emotions of shame guilt and disgust based on a stylized model this article empirically studies the structure and evolution of these moral traits as a function of historical heterogeneity in extended kinship relationships the evidence shows that societies with a historically tightly knit kinship structure regulate behavior through communal moral values revenge taking emotions of external shame and notions of purity and disgust in loose kinship societies on the other hand cooperation appears to be enforced through universal moral values internalized guilt altruistic punishment and an apparent rise and fall of moralizing religions these patterns point to the presence of internally consistent but culturally variable functional moral systems consistent with the model the relationship between kinship ties economic development and the structure of the mediating moral systems amplified over time

taxation by auction fund raising by 19th century indian guilds abstract we describe a unique institution used by 19th century indian guilds to raise funds on certain holidays only one shop was allowed to operate an auction would be held to sell this right and the winning bid would go to the guild fund we compare this taxation by auction mechanism with more conventional tax schemes and show that under certain conditions not only will a majority of guild members prefer to be taxed via an auction but that this form of taxation will be more equitable

heterogeneous labour and the fundamental marxian theorem as was pointed out by morishima at the end of his famous book on marx s economics the heterogeneity of labour is a serious dilemma for marx s theory of exploitation especially for the so called fundamental marxian theorem the problem which should be separated from the peculiarities of joint production consists in finding an appropriate reduction of the various types of labour to one common unit recently bowles and gintis have undertaken an interesting reformulation of the marxian theory of value with respect to heterogeneous labour by avoiding any reduction at all bowles and gintis 1977 1978 cf also steedman 1977 holliinder 1978 but for the purpose of the fundamental marxian theorem this only shifts the problem from the heterogeneity of labour to the heterogeneity of the respective rates of exploitation the aim of the present paper is to extend the fundamental marxian theorem without joint production from homogeneous to heterogeneous labour section 3 this extension is based on a new concept called the standard reduction of labour because of its dual relationship to sraffa s standard commodity section 2 for some arguments a certain type of matrices called sraffa matrices is needed which generalize the quasiirreducible matrices as introduced by bowles and gintis appendix standard reduction implies always a uniform rate of exploitation whereas the same is true for the reduction by wage rates only in special cases for example uniform consumption labour inputs only prices proportional to labour values for the first two cases cf morishima 1978 hence in general standard reduction and reduction by wage rates are different

do sticky energy prices impact the time paths of rebound effects associated with energy efficiency actions abstract there is broad consensus in the policy and academic communities regarding the importance of energy efficiency actions in reducing energy requirements and subsequent greenhouse gas emissions however there is also a requirement to understand the extent to which the technically possible energy savings from exogenously introduced efficiency improvements might be eroded by knock on economic effects which will further change energy use these effects strongly influence the way this rebound phenomenon evolves over time while economy wide drivers of rebound effects are well understood there has been some controversy over the relative sizes of the short and long run rebound effects associated with energy efficiency improvements theoretical analysis predicted that rebound effects would always be greater in the long run than in the short run however numerical general equilibrium simulations have contradicted this result a principal driver of the simulation results is the fully flexible response of energy supply prices to shifting demand however in practice there are a number of reasons for arguing that energy prices are likely to be sticky in this paper we systematically explore the effects of energy price stickiness on the evolution of rebound effects we find that price stickiness is an important determinant of the time path of rebound effects and of their relative size in the short and long runs moreover there is considerable variation in the scale of rebound effects through time especially where short run rebound is lower than its long run counterpart however the most significant overall finding is that rebound reflects the system wide interaction between energy producing and energy using sectors

the impact of increased efficiency in the industrial use of energy a computable general equilibrium analysis for the united kingdom the conventional wisdom is that improving energy efficiency will lower energy use however there is an extensive debate in the energy economics policy literature concerning rebound effects these occur because an improvement in energy efficiency produces a fall in the effective price of energy services the response of the economic system to this price fall at least partially offsets the expected beneficial impact of the energy efficiency gain in this paper we use an economy energy environment computable general equilibrium cge model for the uk to measure the impact of a 5 across the board improvement in the efficiency of energy use in all production sectors we identify rebound effects of the order of 30 50 but no backfire no increase in energy use however these results are sensitive to the assumed structure of the labour market key production elasticities the time period under consideration and the mechanism through which increased government revenues are recycled back to the economy

a missing link in family firms internationalization research family structures hennart majocchi and forlani propose and validate a new explanation of family firms internationalization heterogeneity shedding light on the role of a family firm s global niche business model this type of family firm can avoid the dominant internationalization problems usually depicted in the literature on family firms internationalization starting from the same diagnosis on extant research we explore another perspective to explain this heterogeneity the structure of the family institution we examine the relationships of family structures developed by emmanuel todd in social anthropology to family firms internationalization we explain how todd s typology of family structures can influence the new mechanisms proposed by hennart and colleagues for family firms in europe with a global niche business internationalization finally using these family structures we also reexamine two analyses on family firms internationalization therefore we introduce a new perspective for research on family firms internationalization that is based on context and has critical importance for understanding family firms strategies this new perspective has significance for international business research on family firms

on sraffa s standard commodity the necessity of expressing the relative price of a commodity in terms of another commodity makes it impossible to distinguish that part of any change that can be ascribed to the characteristics of the commodity itself from the part of that change that is to be ascribed to the characteristics of the commodity of reference i e the numeraire ricardo 1817 was the first to point out this problem and the need to find an invariable measure of value but he was not able to solve the problem in 1960 sraffa suggested using a bundle of commodities that he called standard commodity to accomplish this function claiming that it was a standard of value invariant with respect to changes in the distribution of income but in sraffa s book there is no explicit proof of this claim this gave rise to many misunderstandings about the standard commodity and its role as invariable measure of value this paper proposes a proper definition of an invariable measure of value and then proves that the sraffa standard commodity does fulfil the requirements of this definition copyright 2004 oxford university press

endogenous emergence of credit markets contracting in response to a new technology in ghana abstract access to credit is important for the productivity and overall welfare of farmers in developing countries we present a theoretical framework which shows that a change in the mode of shipping from air to sea in the ghanaian pineapple industry made it profitable for pineapple exporters to provide myopic farmers with both in kind loans to improve productivity and cash loans for consumption smoothing despite being unable to monitor farmers or enforce repayment the innovative theoretical result is that providing farmers with additional cash loans can enforce greater input use without compromising repayment we provide evidence in the form of a case study documenting the dramatic rise of informal credit through contract farming after the switch to sea freight between 1996 and 2001 using this anecdote we argue that credit arrangements can arise spontaneously absent non market interventions to meet market needs even in the absence of proper legal protections for creditors

the dynamics of competition a restoration of the classical analysis the main purpose of this article is to show that it is possible to construct a model of competition based on the classical perspective smith ricardo and marx an analysis of the work of the classics is presented and their views of the workings of competition is contrasted with neoclassical and keynesian approaches a simple model with two commodities is constructed in which the stability of the classical long term equilibrium is shown under certain conditions this first model is developed to include the treatments of gravitation rationing deficiency in demand choice of the technology and three commodities copyright 1987 by oxford university press

labour values prices of production and the missing equalisation tendency of profit rates evidence from the german economy during recent years several empirical studies have found that deviations from labour values to market prices are quite small however most of these articles do not offer a detailed reason for this result in this paper two theoretical justifications of the labour theory of value are brought together with some data concerning labour values prices of production and market prices on the basis of german input output tables from 2000 and 2004 in addition the statistical characteristics of profit rates are analysed both of the theoretical arguments are much in line with the empirical observations because there is only a slight transformation tendency and at the same time profit rates and capital intensity are negatively correlated moreover during the period under observation the german economy seems to be in a state of statistical equilibrium copyright oxford university press

profits equal surplus value on average and the significance of this result for the marxian theory of accumulation being a new contribution to engels prize essay competition based on random matrices and on manuscripts recently published in the mega for the first time marx s justification of his theory of surplus value in the face of unequal compositions of capital by interpreting total profits as a redistribution of surplus value is not correct in general however it is shown here that the equality holds if the input matrices are random and the labour theory of value holds in a sense to be specified on average manuscripts recently published for the first time confirm that to the end marx trusted his approach to the theory of value in that he continued to use the identity of the aggregates of capital and surplus in value and in price terms his insistence was rooted in his philosophy an attempt is made to clarify his use of a hegelian methodology by comparing hegel s and marx s approaches to the foundation of the infinitesimal calculus the article concludes with marx s late reconsiderations of his theory of the falling rate of profit which also continue to be based on the equality of profit and surplus value

the deviation of production prices from labour values some methodology and empirical evidence contrary to what is expected from indirect evidence and two commodity hypothetical examples the evdie nce provided in this paper supports david ricardo s empirical proposi tion that relative prices of production are mainly determined by labo r value ratios the results obtained indicate that a 1 percent change in profit rate will cause relative prices to change up to 2 percent and as the profit rate on gross capital is approximately 5 percent o ne ends up with a 90 percent labor theory of value the empirical evidence refers to the yugoslav economy but the factors that determ ine the deviations considered turn out to be of the same order of mag nitude as in other economies copyright 1987 by oxford university press

on the present state of the capital controversy the post war capital controversy seems to have had two distinguishable stages thanks to the unambiguous phenomena of reswitching and reverse capital deepening the first stage was conclusive in discarding from pure theory the traditional versions of neoclassical theory that relied on the notion of capital as a single quantity subsequently however when the implications of those phenomena took centre stage in the controversy together with the reformulations of the theory which intended to do away with the quantity of capital several misunderstandings prevented i shall contend decisive progress in the analysis and we entered an inconclusive phase of the discussion
