occupation and the political economy of trade job routineness offshorability and protectionist sentiment the recent backlash against globalization in many advanced economies raises questions about the source of this protectionist sentiment traditional accounts generally attribute the welfare consequences of trade to skill level or industry characteristics or instead emphasize the nonmaterial determinants of support for openness consequently we know little about how a major labor market characteristic occupation shapes both the distributional consequences of and preferences toward trade openness we propose and test a new theory of trade policy preferences based on occupation characteristics drawing from the tasks literature in economics we argue that occupation characteristics are a key determinant of how trade affects workers and thus individuals trade preferences our theory suggests that in advanced economies individuals in routine task intensive occupations will be negatively affected by trade and thus more protectionist this relationship will increase in the degree to which occupation job tasks can be provided from a distance i e offshorable we find support for our theory using data from the 2003 and 2013 international social survey programme in high income democracies our results suggest that the occupational characteristics of routineness and offshorability are important determinants of trade preferences offering additional understanding of the sources of protectionist sentiment even after controlling for labor market characteristics suggested by conventional wisdom

fragmentation and multinational production abstract this paper examines the consequences of falling transport costs for intermediate goods and shows how this leads to the spatial fragmentation of production as firms divide their production between countries they become either vertical multinationals if upstream activities are labour intensive or horizontal multinationals if downstream activities are labour intensive in the former case the volume of world trade increases and in the latter it falls fragmentation need not narrow international factor price differences which depend on the factor intensity of the activities that relocate

examining the global environmental impact of regional consumption activities part 2 review of input output models for the assessment of environmental impacts embodied in trade this paper offers a detailed review of recently described single and multi region input output models used to assess environmental impacts of internationally traded goods and services it is the second part of a two part contribution in part 1 turner k lenzen m wiedmann t and barrett j in press examining the global environmental impact of regional consumption activities part 1 a technical note on combining input output and ecological footprint analysis ecological economics we describe how to enumerate the resource and pollution content of inter regional and inter national trade flows with the aim to illustrate an ideal accounting and modelling framework for the estimation of ecological footprints a large number of such environment economic models have been described but only in the last few years models have emerged that use a more sophisticated multi region multi sector input output framework this has been made possible through improvements in data availability and quality as well as computability we identify six major models that employ multi sector multi region input output analysis in order to calculate environmental impacts embodied in international trade results from the reviewed studies demonstrate that it is important to explicitly consider the production recipe land and energy use as well as emissions in a multi region multi sector and multi directional trade model with global coverage and detailed sector disaggregation only then reliable figures for indicators of impacts embodied in trade such as the ecological footprint can be derived

the drivers of structural change the main goal of this paper is to provide an integrated survey of the literature devoted to identifying the drivers of structural change broadly defined as the process of reallocation of economic activity across the three broad sectors agriculture manufacturing and services using the ggdc 10 sector database this paper first presents the empirical facts associated with structural change in different regions of the world that is europe and the usa asia latin america and africa then reviews four determinants of structural change i changes in income ii changes in relative sectoral prices iii changes in input output linkages and iv changes in comparative advantage s via globalization and trade

input trade and the location of production stanley engerman has been a presence in the department of economics at the university of rochester for over 37 years he was an early and eminent participant in the cliometric revolution that swept throughout the economichistory profession in the 1960 s and 1970 s we doubt that anyone could have anticipated the gathering storm that greeted the publication of time on the cross co authored with robert fogel in 1974 since that time stan has become the world s leading authority on slavery in the americas and the caribbean as well as an important contributor to a set of issues ranging from the 19th century american iron industry to the economics of british imperialism his own human capital as extensive as we know it to be is complemented by capital of the physical variety an enormous library of research material spilling over into bookshelves and floors in several offices in rochester and attracting a yearly stream of itinerant scholars anxious to pick his books as well as his brains in this short note we intend to honor stan by applying the tools of international trade theory to illustrate several episodes in the development of industries both in the united states and in world markets a colleague of stan s at rochester lionel mckenzie once commented that in 19th century britain lancashire would have been unlikely to produce cotton cloth if the cotton had to be grown in england mckenzie 1954 this remark expresses in utter brevity the importance to production and trading patterns of the domain of tradability of raw materials or intermediate products for example it is difficult to envisage the patterns of production and trade in modern day japan should it be denied access to world supplies of oil coal and iron ore local production of each of these items being negligible transport costs as well as man made impediments to trade are mainly responsible for variations in the degree of access countries possess to the inputs available in the markets of other countries simple competitive generalequilibrium models of production of the type intensively utilized in the theory of international trade can usefully be harnessed to shed light on several episodes in 19th century american economic history in which the nature of trading possibilities for raw materials heavily influenced the extent to which local american production of final commodities could withstand the pressures in world markets without the aid of protective devices the simplest model setting in which to investigate the importance of trade in raw materials is a ricardian model augmented by the necessity of using a produced input in addition to labor in at least one commodity denote the pair of final commodities by x and y where in order to produce y a certain quantity of intermediate good z is required the competitive profit conditions for the two final commodities are shown in equation 1

conceptualising environmental responsibility abstract downstream responsibility is rarely addressed in the academic literature and in corporate sustainability reporting we conceptualise downstream responsibility for the example of carbon emissions by establishing a terminology as well as a framework for quantifying downstream carbon footprints by extracting emissions intensive sales chains for a number of australian industry sectors and comparing these to emissions intensive supply chains we demonstrated the ability of input output analysis to quantify emissions responsibility in both directions we extend the definition of downstream responsibility beyond the product use and disposal phases to include what we call enabled emissions this term implies that whatever is sold downstream enables our customers to operate and emit irrespective of whether it is our product that is combusted or that directly combusts fuels or not our structural path analyses and threshold capture relationships reveal stark differences between industries with regard to the data collection efforts necessary to achieve a reasonably complete footprint assessment industries appear to have their own specific carbon footprint profiles and one cannot design generic relevance tests that tell which data to collect moreover we conclude that current completeness standards in carbon reporting cannot be satisfied using relevance thresholds input output analysis and structural path analysis are excellent tools that can help companies undertake screening exercises which in turn help prioritising and streamlining the collection of data needed to establish a corporate downstream carbon footprint compared to conventional manual approaches hybrid life cycle assessments assisted by input output analysis and structural path analysis achieve more complete results with substantially less staff money and time

shared producer and consumer responsibility theory and practice abstract over the past decade an increasing number of authors have been examining the nexus of producer versus consumer responsibility often dealing with the question of how to assign responsibility for internationally traded greenhouse gas emissions recently a similar problem has appeared in drafting the standards for the ecological footprint while the method traditionally assumes a full life cycle perspective with full consumer responsibility a large number of producers businesses and industry sectors have started to calculate their own footprints see www isa org usyd edu au adding any producer s footprint to other producers footprints or to population footprints which all already cover the full upstream supply chain of their operating inputs leads to double counting the sum of footprints of producers and consumers is larger than the total national footprint the committee in charge of the footprint standardisation process was hence faced with the decades old non additivity problem posing the following dilemma for the accounting of footprints or any other production factor if one disallows double counting but wishes to be able to account for producers and consumers then one cannot impose the requirement of full life cycle coverage the supply chains of actors have to be curtailed somehow in order to avoid double counting this work demonstrates and discusses a non arbitrary method of consistently delineating these supply chains into mutually exclusive and collectively exhaustive portions of responsibility to be shared by all actors in an economy

from production based to consumption based national emission inventories abstract under the united national framework convention of climate change unfccc countries are required to submit national emission inventories nei to benchmark reductions in greenhouse gas ghg emissions depending on the definition and system boundary of the nei the mitigation options and priorities may vary the territorial system boundary used by the unfccc has been critiqued for not including international transportation and potentially causing carbon leakage to address these issues past literature has argued in favour of using consumption based nei in climate policy this article discusses several issues in moving from the standard production based nei to consumption based nei first two distinct accounting approaches for constructing consumption based nei are presented the approaches differ in the allocation of intermediate consumption of imported products second a consistent method of weighting production based and consumption based nei is discussed this is an extension of the previous literature on shared responsibility to nei third due to increased uncertainty and a wide system boundary it may be difficult to implement consumption based nei directly into climate policy several alternative options for incorporating consumption based inventories into climate policy are discussed

a new consumption based accounting model for greenhouse gases from 1948 to 2012 abstract greenhouse gas emissions embodied in international trade have grown rapidly as globalization has progressed and potentially threaten the efficacy of unilateral climate treaties such as the kyoto protocol consumption based methods have been put forward as a way of overcoming this issue and help design future climate policies we improve the long term consumption based accounting lcba model with transfer carbon data from 1948 to 2012 by introducing country specific import intensities and detailed bilateral trade data from uncomtrade comparisons of our new lcba2 model with existing 4 studies show similar consumption based emission patterns both in trend and magnitude and significant emission changes in many european countries the results independently confirm previous findings on the efficacy of the kyoto protocol the results indicate transferred emissions have contributed an historic 36 gt co 2 of cumulative emissions have grown rapidly during the past 30 years up to 8 of total emissions and are likely to become increasingly influential in the near future as the global economy recovers we also use the improved model to study other gases ch 4 n 2 o and so 2 embodied in trade and results indicate similar transfer patterns as co 2 with comparable or even moderately larger magnitudes across method result differences between lcba2 with 3 other models are analyzed based on using common input datasets large emitters show moderate biases within 10 and about 75 of countries have differences within 25 independent of input dataset the lcba2 model provides useful estimates of transferred emissions in both across country and long term historical contexts

interacting factor endowments and trade costs a multi country multi good approach to trade theory abstract we provide a synthetic analysis of the different ways in which countries participate in the world economy classic trade questions are reconsidered by generalizing a factor proportions model to multiple countries multiple goods or multi stage production and country specific trade costs each country s production specialization trade and welfare is determined by the interaction between its relative endowment and its trade costs we consider the effects of allowing one good to fragment into component and assembly production the volume of trade and welfare levels are higher with fragmentation for most countries although for many countries these variables fall with fragmentation

supply side structural effect on carbon emissions in china abstract this paper carries out a structural decomposition analysis sda of production related carbon emissions in china from 1992 to 2005 by adopting the ghosh input output model it finds that the supply side structure measured by sectoral shares in value added increased production related carbon emissions in 1992 2002 mainly due to the rapid growth of manufacturing sectors but reduced them in 2002 2005 thanks to the decreased shares of carbon intensive sectors whatever the supply side structure forward carbon multipliers of each sector or changes in supply side sectoral shares and related emissions effects calculated by adopting the ghosh input output model were different from their demand side counterparts estimated by adopting the leontief input output model the results suggest optimizing the supply side structure and lowering the forward carbon multipliers to control carbon emissions in the future

wage convergence and trade we examine differences in wage rates across countries for workers employed in the same industry distinguishing workers in the low medium and high skill groups these differences are large and show persistence over time we ask nonetheless whether there is evidence of convergence much as is done in studies of convergence in per capita income across countries with our focus on the micro level we expect convergence to reflect at least in part the degree of integration of a country or industry into the world economy and examine particularly the role of market integration and trade our results show strong evidence of convergence in a diverse sample of 39 countries which includes most large economies whether rich or poor the estimated convergence rate over the period from 1995 to 2008 is about 4 per year for workers in all skill groups higher in the more integrated economies of the eu than in other economies without such open borders and lower in industries supplying services rather than manufactures also we find evidence that the rate of growth of domestic output impacts positively on the growth of wages in an industry providing a source for ongoing deviations from the convergence prediction

domestic value chains as stepping stones to global value chain integration identifying the determinants of global value chain gvc integration is essential to understand the past expansion and current slowdown in gvcs in this paper we study the role of domestic value chains dvcs for gvc integration in the presence of industry specific fixed costs of fragmenting production and of switching across input suppliers dvcs can either be stepping stones or stumbling blocks for subsequent gvc entry focusing on backward linkages that is the sourcing of intermediates we provide robust empirical evidence in favour of the stepping stone hypothesis in our benchmark specification a one standard deviation increase in dvc integration raises subsequent gvc integration by about 0 4 to identify the mechanisms at work we exploit two dimensions of industry level heterogeneity product differentiation a proxy of fragmentation costs and relationship specificity a proxy of the costs of switching between suppliers we find that dvc integration is less conducive to gvc integration in industries that are characterised by relatively high switching costs and relatively low fragmentation costs

constructing long term 1948 2011 consumption based emissions inventories accompanying the boom in the global economy co2 emissions have soared over the past several decades with the developing world exhibiting higher emission growth rates than the developed world emissions transfers between regions which represent a significant fraction of total emissions are assumed to be a primary factor contributing to this difference it is important to understand these transfer figures and the resulting consumption based emissions in order to evaluate the emissions drivers and establish climate policies existing studies however have merely estimated figures over a 20 years span post 1990 using a traditional input output analysis ioa framework to broaden the data coverage to pre 1990 of these transfer figures and to further analyze their impacts on total emissions in the long term a new model called the long term consumption based accounting model lcba which is directly based on statistics is developed to span the period from 1948 to 2011 the results are consistent with the magnitudes and trends of existing studies over the validation post 1990 period we use monte carlo methods to calculate upper and lower bounds on the lcba for each country and year and find that 3 existing time series are almost fully included within these boundaries from 1990 furthermore the lcba model is succinct enough to be easily expanded for future ghg estimations or to analyze other ecological footprints related to the flow of materials it can be assumed that the soaring emissions transfers will seriously jeopardize the current climate policies such as kyoto protocol the durban platform for enhanced action adp under which all parties are legally bound will require a consumption based accounting method together with the territorial one in order to achieve an equitable agreement however more researches are still needed to facilitate the use of these figures to better support decision making

understanding the two components of risk attitudes an experimental analysis cumulative prospect theory introduced the weighting of probabilities as an additional component to capture risk attitudes however this addition would be a less significant challenge to expected utility theory eu if utility curvature and probability weighting showed strong positive correlation in that case the utility curvature in eu alone although not properly describing risky behavior in general would still capture most of the variance of individual risk aversion this study provides experimental evidence that such a strong and positive correlation does not exist although most individuals exhibit concave utility and convex probability weighting the two components show no strong positive correlation this paper was accepted by peter wakker decision analysis

international outsourcing and factor prices with multistage production we develop a dual representation of the technology of international fragmentation for an industry using 2 factors in a continuum of stages we then derive a generalised factor price frontier which incorporates an endogenous adjustment of the margin of fragmentation using this frontier in a 2 2 general equilibrium model we investigate the role of outsourcing in the adjustment to a decline in the final output price of the multistage industry and the attendant factor price effects we also explore the implications of an improved technology of international fragmentation on the margin of fragmentation and on domestic factor prices

a review of recent multi region input output models used for consumption based emission and resource accounting abstract the interest in consumption based emission and resource accounting has grown significantly many studies juxtapose consumer emissions carbon footprint and producer territorial emissions of greenhouse gases in order to demonstrate the effects of trade on the national emission budget to this end a respectable number of studies have been undertaken worldwide in order to estimate emissions embedded in international trade of numerous countries and world regions input output approaches and increasingly multi region input output mrio models are commonly chosen as they provide an appropriate methodological framework for complete carbon footprint estimates at the national and supra national level with increasing processing capabilities of computers and a wider availability of economic accounts environmental accounts and trade data such models are now being implemented on a wide scale after a brief overview of salient single region input output studies i provide an in depth review of the most recent multi region input output models used for the purpose of consumption based environmental accounting the main methodological features and important results are described for around twenty studies covering the years 2007 to 2009 this is followed by a detailed review of studies dealing with uncertainty in mrio analysis an area which has not received a lot of attention so far i conclude that further research is mainly needed in two areas a improvements in data availability and quality and b improvements in the accuracy of mrio modelling

the responsibility for carbon emissions and carbon efficiency at the sectoral level evidence from china this work reviews benefit based principles to measuring responsibility for carbon emissions at the sectoral level using environmental input output analysis several new emissions multipliers are proposed to measure sectoral carbon efficiency these principles are used in an empirical analysis of carbon emissions in china and differences between the principles are compared the results indicate that all principles considered can prevent double counting of emissions but that different principles may lead to significantly different attributions of responsibility for carbon emissions and to different multiplier values for particular sectors electricity and heat supply is found to be the sector with the highest emissions responsibility under all but the consumer responsibility principle as well as the highest carbon multiplier under all principles however this sector s responsibility under producer responsibility principles is greater than that under other principles basic metals and transportation and post and telecommunication are among the top five sectors with the greatest responsibilities under all but the consumer responsibility principle whereas construction has the highest consumer responsibility among all sectors the pros and cons and policy implications of each principle are also discussed

factor bias and technical progress abstract the role of factor bias in technical progress has been a bone of contention between labor economists and international trade theorists by considering progress that results in finite changes in techniques these two views can be reconciled for example labor saving technical progress can result in lowered real wages even if it is concentrated in the more labor intensive of two commodities initially produced

trade and protection with multistage production this paper analyses trade in manuf acutured goods that are produced via a vertical production structure with many stages where some value is added at each to an intermediate product to yield a good in process ready for the next stage we consider the stage at which a good is traded to be an economically endogenous variable with comparative advantage determining the pattern of production specialization by stages across countries we study how endowment changes and policy shifts move the margin of comparative advantage which thus provides a channel for resource allocation adjustment that is additional to the usual ones of factor substitution and changes in the quantity of output

consequences of offshoring to developing nations labor market outcomes welfare and corrective interventions our parsimonious two country developed country and developing country model of offshoring provides nuanced results these include cases where wages monotonically improve as well as where wages exhibit an inverted u relationship with offshoring cost reductions we identify conditions under which these relationships hold since global welfare always rises with improvements in offshoring technology we find that there is a role for a minimum wage alternatively wage tax in the developing country we derive such a policy s optimal level there is also the possibility of a developed country optimal offshoring tax for extracting terms of trade benefits we finally analyze the two country nash equilibrium in policies jel f11 f13 f16 f66 o19 o24

some simple results on the gains from trade from growth and from public production abstract a simple compact but general revealed preference type of argument is used to derive results on the gains from trade from terms of trade changes and from exogenous resource growth the approach extends to the welfare evaluation of public sector production the relation between the sufficiency conditions for welfare improvement derived from this approach and the necessary and sufficient conditions derived in an alternative approach are briefly discussed most of the argument is conducted in the context of a representative individual economy though it is shown to extend in an essentially unchanged way to cases where redistribution is an issue

consumer and producer environmental responsibility comparing two approaches abstract two different indicators of environmental responsibility were independently proposed by rodrigues et al rodrigues j domingos t giljum s schneider f 2006 designing an indicator of environmental responsibility ecological economics 59 3 256 266 and lenzen et al lenzen m murray j sack f wiedmann t 2007 shared producer and consumer responsibility theory and practice ecological economics 61 27 42 these indicators are both supposed to reflect the indirect effects of consumer and producer behavior in the generation of environmental pressure in this paper we compare their mathematical properties and interpretation we conclude that they have different implications for environmental policy

does vertical specialization increase productivity this paper investigates the impact of global value chain participation on productivity using data on trade in value added from the world input output database the results based on a panel estimation covering 13 sectors in 40 countries over 15 years suggest that participation in global value chains is a significant driver of labor productivity backward participation in global value chains that is the use of imported inputs to produce for exports emerges as particularly important an increase by 10 percent in the level of global value chain participation increased average productivity by close to 1 7 percent

a consumption based approach to carbon emission accounting sectoral differences and environmental benefits in recent years there has been growing concern about the emission trade balances of countries this is due to the fact that countries with an open economy are active players in international trade trade is not only a major factor in forging a country s economic structure but contributes to the movement of embodied emissions beyond country borders this issue is especially relevant from the carbon accounting policy and domestic production perspective as it is known that the production based principle is employed in the kyoto agreement the research described herein was designed to reveal the interdependence of countries on international trade and the corresponding embodied emissions both on national and on sectoral level and to illustrate the significance of the consumption based emission accounting it is presented here to what extent a consumption based accounting would change the present system based on production based accounting and allocation the relationship of co2 emission embodied in exports and embodied in imports is analysed here international trade can blur the responsibility for the ecological effects of production and consumption and it can lengthen the link between consumption and its consequences input output models are used in the methodology as they provide an appropriate framework for climate change accounting the analysis comprises an international comparative study of four european countries germany the united kingdom the netherlands and hungary with extended trading activities and carbon emissions moving from a production based approach in climate policy to a consumption based principle and allocation approach would help to increase the efficiency of emission reductions and would force countries to rethink their trading activities in order to decrease the environmental load of production activities the results of this study show that it is important to distinguish between the two emission accounting approaches both on the global and the local level

international trade and the geographical separation between income and enabled carbon emissions abstract in this paper we study how international trade allows the geographical separation between the place where carbon emissions occur and the place where income from those emissions is derived we do so by studying the carbon emissions enabled by the primary inputs of products downstream along the production chain we find that 18 of global carbon emissions are enabled abroad and that developed economies fossil fuel exporters and asia account for 80 of the downstream emissions enabled by international trade both developed economies and fossil fuel exporters exhibit a positive trade balance of enabled emissions while for asia the opposite is true developed economies and fossil fuel exporters enable emissions mainly through the export of manufactured products 690 mt and fossil fuels 684 mt respectively while asia exhibits an outflow of enabled emissions through the import of fossil fuels 209 mt the measurement of enabled emissions allows the understanding of how a region s income is derived from carbon emissions occurring abroad

trade in goods and trade in tasks an integrating framework abstract we introduce a simple but flexible analytical framework in which both trade in goods and trade in tasks arise we use this framework to provide versions of the gains from trade and the famous four ho theorems heckscher ohlin factor price equalisation stolper samuelson and rybczynski that apply to this environment we extend our framework to accommodate monopolistic competition and two way offshoring and to integrate theoretical results of the early offshoring literature

globalization and the skilled city abstract the location of economic activity both across and within countries has undergone dramatic shifts over the last five decades three key trends stand out first cross country inequality has declined as many developing countries have grown rapidly second economic geography within countries has instead grown more unequal in both the developed and the developing world third within country spatial disparities have grown mainly because of the disproportionate success of skilled cities in this paper i develop a model that jointly explains these patterns as a consequence of deepening international economic integration my model explains the faster population and output growth of skilled cities as well as their tendency to increase their initial skill advantage consistent with the evidence my theory predicts a non monotonic path of urban growth in developed countries the model predicts a future shift in worldwide urban hierarchies as some developing world cities overtake unskilled cities in industrialized countries along global supply chains

an in depth economic restructuring framework by using particle swarm optimization abstract the aim of this paper is the development of an integrated framework based on environmental input output analysis for optimizing the economic structure of an economy the restructuring process is approached as a constraint optimization problem where the optimized variables are the elements of the matrix of domestic technical coefficients a method for determining the optimal level of the productive linkages of an economy in order to maximize its output with the minimal greenhouse gas emissions the possible is suggested the proposed methodology is able to join both environmental and economic policy targets in the form of predefined constraints the objective function which is going to be minimized expresses the greenhouse gas emissions ghg intensity or ghg emissions per unit of output a particle swarm algorithm is employed for the solution of the optimization problem an illustrative application to the greek economy was carried out the experimental results revealed that if the greek economy will apply policies for boosting the sectors of high and medium high r d intensity then the greenhouse gas emission per unit of gross domestic product of greece would be reduced furthermore the promotion of high and medium high r d intensity sectors is connected with an important improvement of the production linkages to a wide range of sectors highlighting the important spillover effect of the suggested restructuring process

examining the global environmental impact of regional consumption activities part 1 a technical note on combining input output and ecological footprint analysis in recent years there have been a number of attempts to develop a more comprehensive approach to the issue of measuring resource use and or pollution generation embodied in trade flows including contributions that combine input output techniques and ecological footprint analysis in this two part paper we describe how to enumerate the resource and or pollution content of inter regional and inter national trade flows part 1 and we present a literature review of recent methodological and empirical developments part 2 it is straightforward in principle to extend the basic input output approach to capture international trade flows however in practice problems of data availability and compatibility and of computability of extended input output matrices mean that simplifying assumptions are generally applied but with the implications of these assumptions often not made fully explicit what appears to be absent from previous applications is an account of the analytical method by which ecological footprints should ideally be estimated in an international input output accounting analysis this allows an explicit analysis of the problems that prevent the application of the full method and identification of the most appropriate short cut methods in a transparent way the objective of this paper is to provide such an account

a three perspective view of greenhouse gas emission responsibilities in new zealand abstract while responsibility for the environmental impacts of production has been commonly assigned to producers production is driven by consumer demand and it is valid to question whether impacts should instead be assigned to consumers however in each of these approaches producers and consumers either bear the full burden of responsibility or none at all an example of this is the kyoto protocol where all greenhouse gas emissions are assigned to the producer and no consideration is given to where goods are finally consumed rather than taking the conventional producer or consumer responsibility approach a third perspective is possible in which responsibility is shared we use input output analysis to apply all three of these responsibility perspectives to new zealand s domestic greenhouse gas emissions our main findings from the shared responsibility approach are that new zealand producers are responsible for 44 of domestic emissions new zealand consumers take 28 and 27 are exported a shared responsibility approach appears to distribute the burden of responsibility and associated liability between parties more fairly and is likely to be more widely acceptable than pure producer or consumer perspectives

offshoring of routine tasks and de industrialisation threat or opportunity and for whom abstract offshoring or overseas sourcing of routine tasks generates efficiency gains that benefit consumers and workers with skills similar to those whose very jobs are threatened by offshoring essentially the interaction between offshoring footloose capital and agglomeration economies locks the comparative advantage of advanced nations in complex or strategic functions while labour services in routine tasks the coordination of which is easily codified are provided by low wage developing nations through the fibre optic cable in this framework the partial equilibrium view that offshoring is necessarily detrimental to workers in advanced nations is misguided because the implicit counterfactual that keeping the off shored jobs would have no macroeconomic impact on the economy is not warranted in addition inasmuch as routine tasks create few positive feedbacks trade in tasks can be an impediment to income convergence unlike trade in goods in short this paper qualifies the views that offshoring hurts workers in the north and accelerates income convergence between the north and the south

how many us jobs might be offshorable using detailed information on the nature of work done in over 800 us bureau of labor statistics occupational codes this paper ranks those occupations according to how easy hard it is to offshore the work either physically or electronically using this ranking it is estimated that somewhere between 22 and 29 of all us jobs are or will be potentially offshorable within a decade or two no estimate is made of how many jobs will actually be offshored since the rankings are subjective two alternatives are presented one is entirely objective the other is an independent subjective ranking in general they corroborate the rankings albeit not perfectly it is found that there is little or no correlation between an occupation s offshorability and the skill level of its workers as measured either by educational attainment or wages however it appears that controlling for education the most highly offshorable occupations were already paying significantly lower wages in 2004

trade in producer services and returns due to specialization under monopolistic competition this paper demonstrates that liberalizing trade in services while yielding efficiency gains associated with comparative advantage may yield additional gains for both importing and exporting countries because of an increased division of labor a model is developed in which producer services coordinate and control the specialized members of complex production processes the model is used to analyze trade in services and its effect on the division of labor and the realization of returns from specialization this differs from the recent literature on traded services and specialization because of the explicit role introduced for services in the specialization process

income based environmental responsibility abstract a strong mitigation effort is underway to reduce the levels of anthropogenic greenhouse gas emissions an allocation of the mitigation effort among multiple agents requires understanding which agent is responsible for what emissions according to a defined measure of carbon responsibility the metric adopted by current international climate policy is production based or territorial responsibility however other types of responsibility have been discussed in the literature namely consumption based or upstream responsibility and downstream responsibility in this paper we study the latter which is little explored in the literature we clarify the term through a novel nomenclature income based responsibility and present a case study with the quantification of income based responsibility for 112 world regions and the comparison of the results with production and consumption based responsibilities
