remittances from international migration a comparison of el salvador and nicaragua i use household data from el salvador and nicaragua to examine the determinants of remittances from international migration nearly twice as many households in san salvador the capital of el salvador receive remittances from relatives abroad than do households in managua the capital of nicaragua and of those who receive remittances the average remittances received in san salvador is over double that in managua 119 month to 45 month the difference is explained by differences in the behavioral coefficients and by differences in the self selection bias of those who remit out of the pool of emigrants between the two countries excerpt

nonparametric estimation of sample selection models sample selection models provide an important way of accounting for economic decisions that combine discrete and continuous choices and of correcting for nonrandom sampling nonparametric estimators for these models are developed in this paper these can be used for estimating shapes and important economic quantities as in standard nonparametnc regression endogeneity of regressors of interest is allowed for series estimators for these models are developed which are useful for imposing additivity restnctions that arise from selection corrections convergence rates and asymptotic normality results are derived an application to returns to schooling among australian young females is given

strikes and holdouts in wage bargaining theory and data we develop a private information model of union contract negotiations in which disputes signal a firm s willingness to pay previous models have assumed that all labor disputes take the form of a strike yet a prominent feature of u s collective bargaining is the holdout negotiations often continue without a strike after the contract has expired production continues with workers paid according to the expired contract we analyze the union s decision to strike or hold out and highlight its importance to strike activity strikes are more likely to occur after a drop in the real wage or a decline in unemployment

the determinants of migrant remittances this article explores the factors that account for variation in remittance flows why do some immigrants send much more money to their country of origin than others this is a question that in the aggregate has implications for national economies and migration related policy the analysis departs from the classic studies of remittances and considers how the context of contemporary migration in europe is likely to affect remittance patterns possible influences on remittance sending are disaggregated into nine domains and each is discussed with reference to theoretical arguments and empirical findings the temporal aspects of remittance sending are discussed separately the final section of the article considers implications of the micro level analysis for aggregate remittance flows and policy it is argued that the focus on altruism versus self interest in the literature has partly diverted attention from explaining the actual variation that is important in a policy perspective

the enduring power of coase abstractby many measures ronald coase has been among the most influential economists of the past 60 years why is this so we suggest that coase s work has enduring appeal to and insight for social scientists in part because it addresses the biggest and most important social problems how do we solve governance and coordination problems when limited information common resource issues and public good issues produce conflicts among several people at once any scholar who works on issues of corporate or common pool governance pollution allocation of seats on legislative committees regulation of systemic risk in financial markets provision of military forces patent thickets creation of optimal communications networks regulation of decreasing cost industries or compensation of corporate officers can see his or her work stemming from several of coase s original insights just as john nash s work reshaped economic theory almost every field of economics and political science is shaped by coasean insights

unions and strikes with asymmetric information strikes seem to be a pareto inefficient outcome of bargaining between a union and a firm however this paper shows that strikes can be the outcome of rational behavior by both agents if the firm has more information than the union concerning the state of nature the union can use strikes as a way of gaining information the paper uses an asymmetric information model where the firm has information about the state i e profitability that the union does not know the schedule of wage offers by the union then depends on the probability that a given state will occur

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

responsibility and trade emission balances an evaluation of approaches this paper compares two concepts to evaluate the international responsibility of a country with respect to its emissions using a multi regional input output model we show that the trade emission balance and the responsibility emission balance yield the same result in practical work however a lack of data availability implies that the same technology assumption has been commonly adopted in that case also a third alternative exists which simply evaluates the emissions embodied in the trade balance of the country this third alternative yields the same results as the other two approaches at the aggregate level at the level of individual products however the results are clearly different and it turns out that the third alternative answers a different question that is it is appropriate for measuring the emission content of the products that cross the border in our empirical application we consider spain in 1995 and 2000 distinguishing nine different gases co 2 ch 4 n 2 o sf 6 hfcs pfcs so 2 nox and nh 3 c 2010 elsevier b v all rights reserved

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

embodied carbon in china s foreign trade an online sci e and ssci based literature review abstract this paper systematically presents a survey of the empirical literature studying the embodied co2 emissions in china s foreign trade ecct based on the bibliometric method and the online version of science citation index expanded sci e and social sciences citation index ssci this study summarizes the latest publications regarding ecct in peer reviewed journals in terms of quantities most productive countries institutions authors citations and disciplines by using synthetic analysis of keyword frequency this study reveals the most popular methodologies applied in measuring ecct discusses the variation of numerical results in the literature and reasons and countermeasures for the results uncertainties continuous investigation of the literature releases the methodology employed for measuring ecct becoming more reasonable and the results more critical however the numerical results of ecct are of great discrepancies within given year by different considerations on methodology specification accounting principles and data sources and processing for instance the estimates of co2 embodied in china s exports changed from 478 mt to over 3000 mt and those of in china s imports ranged from 140 mt to over 1700 mt in 2007 therefore overcoming data inherent limitations and reducing discrepancies among available databases should be urgently considered the results imply that the prospective research tendencies on ecct are to 1 improve china s regional input output data and energy intensity data to more precise estimates under global perspective 2 estimate china s carbon emission at firm level by different firm ownerships in production and consumption worldwide 3 assess china s carbon emission from processing or non processing trade by compiling more detailed multi regional input output table 4 evaluate city level carbon mitigation capacity in china under global mrio model 5 explore new carbon management experience in china s carbon trading market and new trade expansion policy of one belt and one road in her new growth era

savings remittances and return migration abstract using a vast west german data set the paper shows that savings and remittances of migrants can be well explained by remigration plans and economic as well as demographic variables however the planned future duration of residence in germany has a negative and significant effect only on remittances

sharing norm pressures and community remittances evidence from a natural disaster in the pacific islands abstractmigrants are often subject to social pressures to remit beyond their own households to share the benefits of migration with the wider community in their home country these are community remittances we hypothesise that community sharing norm pressures are stronger in locations with more extensive home community networks we also postulate that the responsiveness of remittances to sharing pressures is subject to diminishing returns attributable to a donor fatigue effect using customised survey data from three polynesian migrant groups in metropolitan and regional australia we estimate double hurdle regression models of community remittances to identify the effects of sharing norm pressures we exploit an exogenous cyclone shock to home country incomes affecting one sub group we find strong evidence in support of the postulated responsiveness of community remittances to location related differences in sharing norm pressures and the presence of a donor fatigue effect the policy implicatio

delays in renewal of labor contracts theory and evidence in many countries an expired labor contract is automatically extended during the often protracted delay before the new contract is signed our theoretical model focuses on macroeconomic factors in explaining the delay it emphasizes the importance of the realized nominal and real shocks and of the levels of nominal and real uncertainty the model is tested using israeli collective wage agreements where long delays are frequent the empirical findings strongly support the theoretical model thus nominal uncertainty is found to increase the delay and real uncertainty to decrease the delay but less in the public than in the private sector

the rise and fall of the dollar a comment if readers of this paper were to ask themselves what the rates for the world s major currencies are likely to be in say three years time it is doubtful whether they would have much confidence in their predictions even conditional forecasts on the basis of particular assumptions about policy would be hard to make this state of ignorance and our admission of it owes much to the recent behaviour of the dollar which as koromzay llewellyn and potter so usefully discuss largely defies explanation in terms of conventional economic analysis even when full use is made of the luxury of hindsight that ignorance itself may however have important policy implications these comments relate to both the theoretical and policy aspects of the paper though the focus as in the paper itself is on the implications for policy a general difficulty may be stated at the outset the paper reasonably enough concentrates on the dollar in the i98os but though this is much the most dramatic illustration of the difficulties in explaining exchange rate movements it is not the only one thus ideally an explanation of dollar strength should be consistent with explanations given for previous dollar weakness see for example bliss i986 and for other recent major movements of exchange rates such as the apparently similar gravity defying rise in sterling in the late i970s and early 198os where theory and empirical analysis fail explanations tend to become ad hoc with a danger that false or over strong policy conclusions are drawn even a casual comparison with the united kingdom raises some questions as well as supporting the general thrust of this paper thus the monetary fiscal mix in the united kingdom was very different from that in the united states according to oecd figures the structural budget moved to surplus by some 6 of gdp between i979 and i982 which must at least suggest a cautious approach to some of the simpler stories that trace the rise in the dollar to united states fiscal irresponsibility the united states experience which as the paper demonstrates does not accord with conventional models of the overshootingtype also throws doubt in the other direction about applications of that kind of model to the united kingdom for example by buiter and miller i98i of course the united kingdom s situation was special because of north sea oil but if north sea oil was important the obvious reason would be due to its effect on relative current account positions which does not seem to work well for the united states and in any case most estimates suggest that oil should account for only a part of the rise in sterling see powell and horton i985 for a survey and as in the united states empirical models were notably unsuccessful in predicting the exchange rate haache and townend i98i

input output analysis of carbon emissions embodied in china japan trade abstractenergy related co2 emissions embodied in international trade have been widely studied by researchers all over the world by using the bilateral trade input output btio approach this study investigates the co2 emissions embodied in china japan trade during 1995 2009 and attempts to identify the driving forces for the change in co2 emissions embodied in china s exports to japan during that period by using structural decomposition analysis sda result shows that co2 emissions embodied in china s exports increased by about 100 from 1995 to 2009 whereas those embodied in china s imports increased by about 500 during the same period result of this research also reveals that the scale effect had a large influence on the increase in co2 emissions embodied in china japan trade the technical effect greatly decreased co2 emissions embodied in china s exports to japan but obviously increased those embodied in imports the influence of the structural effect was relatively small and insignificant in

aggregation in variance of shared responsibility a case study of australia abstract this article deals with shared producer and consumer responsibility a concept aimed at overcoming the non additivity or double counting problem in corporate and national sustainability reporting it reports on the potentially distorting effects that varying sector and business classifications could have on the apportioning of emissions or other sustainability measures amongst producers and consumers in an economy a quantitative in variance analysis is provided which shows that shared responsibility formulations are remarkably stable under extreme aggregation of the underlying input output data value added pegging of the sharing parameters generally reduces variance in comparison to constant sharing parameters these results help in substantiating the robustness of the shared responsibility concept a feature which is critically important if shared responsibility were to become corporate and national reporting practice

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

are international remittances altruism or insurance evidence from guyana using multiple migrant households abstract while international remittances provide significant disposable income for many households in less developed countries there is no consensus on migrants remittance motivation two principal competing explanations for remittances are altruism and risk sharing this paper employs previously unanalyzed data to bring new evidence to the debate we develop a simple theoretical model that yields distinct testable predictions for each motivation among the model s testable predictions is differential remittance behavior by migrants from households with multiple versus single migrants under altruism and risk sharing our estimation finds significant differences in remittance behavior of multiple and single migrants and these differences support the altruistic incentive to remit

unemployment and female labour supply the definition of labour force participation in the standard labour supply model stands in sharp contrast to that used in compiling the labour force statistics in the labour supply models only those supplying positive hours of work are considered to be labour force participants on the other hand participation in the labour force statistics is often defined to include not only those supplying positive hours but also those actively searching for work this paper is an attempt to reconcile these concepts by allowing unemployed workers to enter a generalisation of the standard labour supply model this turns out to be a convenient way to enter demand side factors directly into the determination of an individual s labour market position the model is applied with some success to the working behaviour of married women in the uk family expenditure survey

motivations to remit evidence from botswana in this article a theory of motivations to send remittances is described and tested with data from botswana altruism is one of the motivations tested and found to be an insufficient explanation for remittances among migrants in botswana a refinement of the model stipulates a modified altruism or enlightened self interest in this model the relationship between the migrant and family is tempered by an implicit understanding of mutual benefit the household strategy may be to encourage some members to migrate as a means of spreading risk and sharing gains the household strategy is similar to an insurance policy where migration is to places where market potential is high the risks incurred might be high the example is given of migration during a drought in botswana migrant remittances were greater in households with more cattle or households with more to lose drought alone was not statistically related to remittances increases in remittances were related to increased levels of education it is suggested that repayment was the motive for parents investment in migrants education migrants gains are identified as the potential for an inheritance the security of channeling investments through a trusted family member and security in having a home to return to it is pointed out that the altruism and family remittances from urban migration were strategies that bridged the simple dynamic of either urban development or rural development impacting on family welfare it is suggested that household models of economy adopt some measure to express the relationship of household wealth to remittances from urban migrants

a theory of holdouts in wage bargaining holdouts the continuation of negotiations beyond the contract expiry date are the most common form of disputes in labor contract negotiations the authors model holdouts as a delaying tactic employed by unions to obtain information about other bargaining outcomes in their industry novel implications of their model include a positive association between holdout duration and the number of bargaining pairs negotiating contracts simultaneously bunching of holdout durations within these negotiating groups and fewer strikes among holdouts which end later in groups using a large panel of contract negotiations in canadian manufacturing the authors find considerable support for these predictions copyright 1998 by american economic association

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

remittance receipts and allocation a study of three african countries remittances may influence household expenditures poverty rates development and investments in the receiving country using world bank survey data from ethiopia uganda and kenya the influence of remitters and recipients characteristics on remittance amounts and allocation is examined effects of the remitter receiver characteristics on remittance amounts are generally similar between countries such similarities imply a potential similar effect of policies in these countries age household income frequency of communication family relations with remitter and country the recipient resided in influence remittance allocation recipients in ethiopia and uganda are more likely to allocate remittance towards savings than those in kenya

remittances and savings from international migration theory and evidence using a matched sample abstract the central question of this paper concerns the implications of remittance flows for migrants and their origin households in the country of origin this paper represents the first attempt to present a disaggregated view of international remittance flows using a matched sample of international migrants and their origin families i investigate two types of remittances transfers to the home family and savings in the country of origin the empirical evidence provides support for the altruistic model of transfer behavior wealthier origin families tend to receive lower transfers other things being equal however remittances sent to finance origin country investments are positively associated with origin household wealth the estimation strategy addresses two common problems that arise in investigating remittance behavior omitted variable bias and the measurement of origin household resources

cyclical fluctuations in strike durations canadian data on strikes between 1946 and 1983 are used to estimate linear regression models for the logarithm of completed duration a thorough investigation of the influence of the business cycle reveals strong support for the hypothesis that strike durations are countercyclical the cyclical effect is shown to be robust to both the choice of cyclical variable and the econometric specification and the magnitude of the effect is quite substantial experimentation with different representations of the cycle reveals that it is difficult to improve on a simple formulation involving a single continuous variable

remittances transaction costs and informality abstract recorded workers remittances to developing countries reached 167 billion in 2005 bringing increasing attention to these flows as a potential tool for development in this paper we explore the determinants of remittances and their associated transaction costs we find that recorded remittances depend positively on the stock of migrants and negatively on transfer costs and exchange rate restrictions in turn transfer costs are lower when financial systems are more developed and exchange rates less volatile the negative impact of transactions costs on remittances suggests that migrants either refrain from sending money home or else remit through informal channels when costs are high we provide evidence from household surveys supportive of a sizeable informal sector

remittances and vulnerability in developing countries this paper examines how international remittances are affected by structural characteristics macroeconomic conditions and adverse shocks in recipient economies we exploit a novel rich panel data set covering bilateral remittances from 103 italian provinces to seventy nine developing countries over the period 2005 2011 we find that remittances are negatively correlated with the business cycle in recipient countries and in particular increase in response to adverse exogenous shocks such as large terms of trade declines this effect is stronger where the migrant communities have a larger share of newly arrived migrants finally we show that recipient country financial development is negatively associated with remittances suggesting that remittances help alleviate credit constraints

an experimental study of the holdout problem in a multilateral bargaining game abstract when an economic exchange requires agreement by multiple independent parties the potential exists for an individual to strategically delay agreement in an attempt to capture a greater share of the surplus created by the exchange this holdout problem is a common feature of the land assembly literature because development frequently requires the assembly of multiple parcels of land we use experimental methods to examine holdout behavior in a laboratory bargaining game that involves multi person groups complementary exchanges and holdout externalities the results of six treatments that vary the bargaining institution number of bargaining periods and the cost of delay demonstrate that holdout is common across institutions and is on average a payoff improving strategy for responders both proposers and responders take a more aggressive initial bargaining stance in multi period bargaining treatments relative to single period treatments but take a less aggressive bargaining stance when delay is costly nearly all exchanges eventually occur in our multi period treatments leading to higher overall efficiency relative to the single period treatments both with and without delay costs

estimating remittance functions for pacific island migrants there is concern that pacific island economies dependent on remittances of migrants will endure foreign exchange shortages and declining living standards as remittance levels drop due to lower migration rates and the belief that migrants willingness to remit decreases over time the empirical validity of the remittance decay hypothesis has never been tested from survey data on tongan and western samoan migrants in sydney this paper estimates remittance functions using tobit regression analysis it is found that the remittance decay hypothesis has no empirical validity and migrants are motivated by factors other than altruistic family support including asset accumulation and investment back home c 1997 elsevier science ltd

network effects and the dynamics of migration and inequality theory and evidence from mexico international migration is costly and initially only the middle class of the wealth distribution may have both the means and incentives to migrate which can increase inequality in the sending community however the migration networks formed lower the costs for future migrants which can in turn lower inequality this paper shows both theoretically and empirically that wealth has a nonlinear effect on migration and then examines the empirical evidence for an inverse u shaped relationship between emigration and inequality in rural sending communities in mexico after instrumenting we find that the overall impact of migration is to reduce inequality across communities with relatively high levels of past migration we also find some suggestive evidence for an inverse u shaped relationship among communities with a wider range of migration experiences

attributional or consequential life cycle assessment a matter of social responsibility abstract results of life cycle assessment lca are critically dependent on the system boundaries notably the choice of attributional or consequential modelling published lca studies rarely specify and justify their modelling choices since lca studies are typically performed within the context of social responsibility and product life cycle management this article investigates the relationship between social responsibility paradigms and the system modelling choices in lca we identify three different social responsibility paradigms value chain responsibility supply chain responsibility and consequential responsibility we point out that while there is no generally right or wrong choice of system model each responsibility paradigm implies a specific matching system model we then argue that all responsibility paradigms ultimately imply a consequential perspective namely that of responding to the concerns of the system stakeholders although value or supply chains are systems defined without concern for consequences and thus may include activities that the decision maker cannot influence the chosen system is still analysed and assessed by accounting for its social consequences and it is for these consequences that social responsibility is then taken we argue that it is inconsistent to exclude consequences of own actions i e the consequential system while including consequences from actions of others in value chain or supply chain we thus conclude that a consistent socially responsible decision maker must always take responsibility for the activities in the consequential product life cycle and may additionally take responsibility for the consequences of other activities in the value chain or supply chain we end the article with recommendations on reporting on lca system models that are more specific than those of the current lca standards

economic drivers of greenhouse gas emissions in china abstract for china greenhouse gas emissions increased by 0 075 gigatons gt in the period of 1995 2000 and increased by 4 23 gt from 2000 to 2009 then reached the amount of 8 61 gt in 2009 different from the traditional analysis focused on accounting sectors greenhouse gas emissions under the production based responsibility this paper investigates sectoral ghg emissions in china in the period of 1995 2009 from the perspective of consumption based and income based responsibility we found that different metrics yield very different ghg emission responsibilities the sector of electricity gas and water supply has the highest ghg emissions responsibility based on the production and income metrics while the sector of construction is the largest emitter under the consumption metric in the light of the key driver analysis of ghg emissions from 1995 to 2009 based on the consumption metric the change in the final demand volume is the largest driver of increase in china s consumption based ghg emissions 17 18 gt the changes in the production structure and the final demand structure are other contributors 0 53 gt 1 46 gt the improvement to the intensity of ghg emissions is the main force for ghg emissions mitigation 14 86 gt according to the income metric the contributions of input volume changes input structure changes and ghg intensity changes are similar to the effects of consumption based responsibility 19 11 gt 1 13 gt 14 95 gt the difference is that the change in the production structure is another force that offset ghg increase 0 98 gt results in this paper can give some recommendation on mitigating ghg emissions in china for policy makers from production side demand side and supply side

international migration remittances and household investment evidence from philippine migrants exchange rate shocks how do households respond to overseas members economic shocks overseas filipinos in dozens of countries experienced sudden heterogeneous changes in exchange rates during the 1997 asian financial crisis appreciation of a migrant s currency against the philippine peso leads to increases in household remittances from overseas the estimated elasticity of philippine peso remittances with respect to the exchange rate is 0 60 positive migrant shocks lead to enhanced human capital accumulation and entrepreneurship in origin households child schooling and educational expenditure rise while child labour falls households also work more hours in self employment and become more likely to start relatively capital intensive household enterprises

holdouts backdating and wage negotiations the haller and holden jet 1990 wage bargaining model is extended to incorporate holdouts with and without work to rule inefficient holdouts and backdating of new contracts the union s most effective action inflicts the highest costs upon the firm among the credible actions necessary and sufficient conditions for equilibria with lengthy holdouts are derived backdating does not affect the bargaining positions of the parties the settlement wage negatively depends upon the length of the holdout and this dependence does not disappear as the time between bargaining rounds vanishes this result has implications for empirical work moreover this negative effect is small and confirms empirical evidence for the netherlands

modeling reductions in the environmental footprints embodied in european union s imports through source shifting the european union eu is responsible for a disproportionately large share of global environmental footprints in particular those embodied in trade through its imports import embodied footprints iefs vary significantly depending on the country of origin and therefore can be reduced through source shifting we explore the impacts of shifting imports to the countries with lowest impact intensities per m according to four environmental pressures carbon emissions materials water and land using environmentally extended multi regional input output eemrio analysis there are significant limitations of eemrio analysis the price and product mix homogeneity assumptions which we discuss in the paper we find that a limited set of 13 products among which food products and chemicals which are not elsewhere classified n e c is responsible for more than half of all impacts embodied in imports for each pressure except for a few product groups optimizing sourcing as to minimize impact for one pressure reduces impact in all others the pressure exhibiting the highest scope for optimization is water carbon and material use optimization yields the largest reduction in other environmental pressures we discuss increasing the policy relevance of eemrio in the case of iefs by disaggregating n e c product groups and incorporating dynamic effects 2019 elsevier b v

second best mechanisms for land assembly and hold out problems abstract land can be inefficiently allocated when attempts to assemble separately owned parcels are frustrated by holdouts eminent domain can be used neither to gauge efficiency nor to determine adequate compensation we characterize the least inefficient class of direct mechanisms that are incentive compatible self financing and protect the property rights of participants the second best mechanisms which we call strong pareto sp utilize a second price auction among interested buyers with a reserve sufficient to compensate fully all potential sellers who are paid according to fixed and exhaustive shares of the winning buyer s offer these mechanisms are strategy proof dominant strategy incentive compatible individually rational and self financing they generate higher social welfare in each problem compared to any other type of mechanism satisfying these properties

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

motives for private transfers over the life cycle an analytical framework and evidence for peru abstract this paper tests for the motives for private income transfers we consider two motives altruism and exchange the question of private transfer motives is important because such motivation can influence the effects of public income transfers on the distribution of income using a household survey for peru we find that transfer amounts received increase with recipient pre transfer income which contradicts a key prediction of the strong form of the altruism hypothesis but is consistent with exchange we also find that capital market imperfections are likely to be an important cause of private transfers and that social security benefits crowd out the incidence of private transfers

on sustainability interpretations of the ecological footprint abstract this paper focuses on using the ecological footprint concept for sustainability assessment the ecological footprint is a popular indicator of human use of environmental resources and is commonly presented at the country level by comparing the consumption footprint with territorial biocapacity with a negative balance implying unsustainability this constrains a country s consumption by its biocapacity but allows its stock of resources to be depleted if they are not associated with domestic consumption this paper argues that this approach is legitimate but should not automatically constitute a default framework for interpretation two perspectives on entitlements to environmental resources are analyzed and based on them a novel approach to sustainability assessment is proposed the paper further discusses the links between national sustainability and the related issues of self sufficiency consumption and responsibility

international trade and shared environmental responsibility by sector an application to the spanish economy abstract the aim of this paper is to define a shared responsibility criterion for analysing the impact of international trade on co 2 emissions applied to sectors with the approach proposed it is possible for sectors in a country to account for only a part of the emissions associated with exported and imported goods the agents considered as responsible for pollution are sectors two fold as producers and suppliers of intermediate inputs and final demand accounting for direct emissions linked to production and as consumers of intermediate inputs required for production accounting for direct and indirect emissions linked to consumption of inputs and the countries and foreign sectors that trade with these industries the responsibility of emissions is shared by all the participants along the global product chain depending on the value added of each step the criterion is applied to the spanish economy for the period 2000 to 2005 and proves useful for determining what economic policies may be suitable for mitigating anthropogenic impact on the environment and for including all the agents of the supply chain in the development of sustainable supply chain management

striking for a bargain between two completely informed agents this paper models the wage contract negotiation procedure between a union and a firm as a sequential bargaining process in which the union must decide in each period whether or not to strike for the duration of that period we show that there exist subgame perfect equilibria in which the union engages in several periods of strikes prior to reaching a final agreement although both parties are completely rational and fully informed this has implications for other inefficient phenomena such as tariff wars debt negotiations and wars in general we characterize the set of equilibria show that strikes can occur in real time and discuss extensions of the model such as lockouts and the possibility of multiple recontracting opportunities copyright 1991 by american economic association

trade from resource rich countries avoids the existence of a global pollution haven hypothesis abstract free trade agreements are currently receiving much attention in the media and politics one important question concerning free trade is its effect on the environment for example in carbon dioxide emissions the goal of this paper is to provide evidence on the validity of the pollution haven hypothesis using a multi regional input output approach for six regions and the rest of the world as a whole our findings indicate that in the period from 1995 to 2009 international trade has allowed the global economy to reduce its overall co2 emissions compared to a hypothetical situation without international trade the total amount of emissions saved was 15 06 gt in the period under consideration however not all of the seven regions in our model have been able to reduce their co2 emissions through trade global value chains have led to china becoming a pollution haven for other regions and its exports have increased world emissions to 1 28 gt co2 in 2008 however what allows a net saving of emissions on a global scale is the supply of energy and natural resources from a set of peripheral economies which in our geographical categorization are mostly integrated in the region of the rest of the world

mapping the international flows of ghg emissions within a more feasible consumption based framework abstract during the last two decades the scientific literature has focused on the allocation of emissions embodied in international trade by implementing accounting procedures based on consumer oriented perspective while the multi regional input output analysis has been accepted by the scientific community as an alternative to the ipcc accounting some concerns arise from the feasibility and the actual implementation of this methodology in this paper we apply a simplified framework recently introduced by caro et al 2014a called nci national carbon intensity method and estimate the total co2 emissions due to consumption in 175 countries during the period 2008 2012 with a focus on the mediterranean area we estimate co2 emissions embodied in trade assigning emission responsibility on the basis of each country s demand globally in 2012 8129 mt co2 emissions were related to goods produced in one country and consumed outside its boundaries a relevant example is the export from china to consumers located in the usa japan and germany a focus on the mediterranean area that resulted as a net importer of co2 embodied in traded goods identifies the export of emissions from italy and spain to france and from libya and algeria to italy as the dominant flows the nci method provides a realistic picture of emissions due to consumption that differs from high resolution multi regional input output database by less than 10 the method can be largely adopted as a more feasible preliminary step towards consumption based emission accounting and responsibility assignment

the effect of increasing exports on industrial energy intensity in china abstract given china s heavy reliance on fuel energy and the dominance of its industrial sector in the economy improving energy efficiency remains one of the practical means for the country to decrease energy intensity and to fulfill its commitment made at the copenhagen climate change conference to achieve a 40 45 percent reduction in co 2 emission intensity by 2020 this study investigates the impact of exports on industrial energy intensity to explore the possibility of reducing energy intensity through greater exports a panel varying coefficient regression model with a dataset of china s 20 industrial sub sectors over 1999 2007 suggests that in general greater exports aggravate energy intensity of the industrial sector and that great divergences exist in the impact of exports on energy intensity across sub sectors a panel threshold model further estimates the thresholds for the major determinants of energy intensity exports input in technological innovations and foreign direct investment fdi intensity given the great differences in specific sub sector characteristics and the changing roles played by different factors across sub sectors there is no general export policy that would work for all sub sectors in reducing sub sector energy intensity instead policies and measures aiming to encourage more efficient use of energy should take into full consideration the characteristics and situations of individual sub sectors

a double hurdle model of cigarette consumption this paper shows the importance of the double hurdle approach for modelling individuals cigarette consumption using data from the uk general household survey and argues that participation and consumption should be treated as separate individual choices the likelihood function for the full double hurdle is derived and it is shown how restrictions on the stochastic specification of the model and auxillary information which identifies ex smokers allow it to be decomposed the empirical results highlight the value of the sample separation information and the need to model starting and quitting as separate decisions

technology adjusted national carbon accounting for a greener trade pattern abstract crediting green trade patterns is essential for effective national carbon accounting neither production nor consumption based accounting satisfies this condition thus kander et al kander a jiborn m moran d d wiedmann t o 2015 national greenhouse gas accounting for effective climate policy on international trade nature climate chang 5 5 431 435 proposed a technology adjusted consumption based carbon accounting method that focuses on interregional differences in sectoral carbon intensity the intermediate input structure is also closely related to the production technology level therefore this study recommends a new technology adjusted consumption based carbon accounting framework that distinguishes between direct and cumulative exports forward and backward industrial linkages and different trade patterns based on the consideration that production based accounting will remain the core indicator for regional emissions in the near future this study proposes a technology adjusted production based accounting framework the empirical study is based on the world input output database and the results indicate that technology adjusted carbon accounting will redraw the global emissions map if the intermediate input linkage is considered the technology adjusted carbon accounting method satisfies the conditions of additivity sensitivity monotonicity and scale invariance through proper selection of the world average emissions multipliers

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

provincial responsibility for carbon emissions in china under different principles abstract by applying a multi regional input output model the study compares the provincial responsibility for carbon emissions and provincial carbon multipliers in china under seven responsibility allocating principles including three basic principles the production income and consumption principles and four shared responsibility principles the income weighted consumption weighted comprehensive and weighted comprehensive principles empirical results indicate that carbon multipliers of provinces under these principles are significantly different from one another the carbon multipliers of provinces with higher ratios of carbon intensive sectors in their outputs are also larger at the same time the carbon multipliers of the same sector in the provinces are significantly different from one another changing the principle causes significant changes in the responsibility for carbon emissions of some provinces but only slight changes in the responsibilities of some other provinces however the responsibilities of provinces with large economic sizes output are always the largest whereas provinces with the smallest economic sizes are always the smallest regardless of the principles further this study proposes a series of regional policies for carbon mitigation according to provincial carbon multipliers and responsibility allocation features under the different principles

quo vadis mrio methodological data and institutional requirements for multi region input output analysis abstract in order to understand wider sustainability impacts of consumption and to successfully promote and implement sustainable consumption and production policies there is a need to capture the whole life cycle impact of products and services across international supply chains multi region input output mrio databases are a well described and suitable foundation for global sustainability analyses addressing a wide range of policy and research questions in this paper we reflect on the reasons for the recent boom in mrio compilation summarise the current state of development and discuss future options for mrio analysis we list in detail the requirements for efficient and effective mrio research and propose systemic and institutional changes we deliberately try to go beyond existing ambitions for mrio compilation and thus intend to stimulate discussion and to lay out the options for the future of mrio research

endogeneity and sample selection in a model for remittances abstract we estimate a remittance model in which we address endogeneity and reverse causality relationships between immigrants remittances pre transfer income and consumption in order to take into account the fact that a large share of individuals do not remit instrumental variable variants of the double hurdle and heckit selection models are proposed and estimated by limited information ml semiparametric extensions are considered as robustness checks our results for a sample of recent immigrants to australia show that endogeneity is substantial and that estimates obtained by the methods previously employed in the literature may be misleading if given a behavioral interpretation

strikes and wages a test of an asymmetric information model this paper describes a simple model of labor disputes based on the hypothesis that unions use strikes to infer the profitability of the firm the model posits the existence of a negatively sloped resistance curve between wages and strike duration in addition it offer a series of predictions relating wage and strike outcomes to changes in the expected profitability of the firm and changes in the alternative opportunities of striking workers these implications are tested using data on wage outcomes strike probabilities and strike durations for a large sample of collective bargaining agreements

remittances and temporary migration in this paper we study the remittance behavior of immigrants and how it relates to temporary versus permanent migration plans we use a unique data source that provides unusual detail on remittances and return plans and follows the same household over time our data allows us also to distinguish between different purposes of remittances we analyze the association between individual and household characteristics and the geographic location of the family as well as return plans and remittances the panel nature of our data allows us to condition on household fixed effects to address measurement error and reverse causality we use an instrumental variable estimator our results show that changes in return plans are related to large changes in remittance flows

longitudinal analysis of strike activity this article presents an empirical study of strike activity in a panel of contract negotiations for some 250 firm and union pairs evidence is presented on two sources of variation in dispute rates changes in the characteristics of the collective bargaining agreement that affect subsequent strike outcomes and the effects of lagged strikes on the incidence and duration of subsequent disputes strike probabilities are significantly affected by the duration and expiration month of the previous agreement dispute rates are also increased by the occurrence of a short strike during the previous negotiations and reduced by the occurrence of a long strike

wage rigidity collective bargaining and the minimum wage evidence from french agreement data using several unique data sets on wage agreements at both industry and firm levels in france we document stylized facts on wage stickiness and the impact of wage setting institutions on wage rigidity first the average duration of wages is a little less than one year and around 10 percent of wages are modified each month by a wage agreement data patterns are consistent with predictions of a mixture of calvo and taylor models the frequency of wage change agreements is rather staggered over the year but the frequency of effective wage changes is seasonal the national minimum wage has a significant impact on the probability of a wage agreement and on the seasonality of wage changes negotiated wage increases are correlated with inflation the national minimum wage increases and the firm profitability

the effect of labour relations legislation on strike incidence the impact on strike incidence of nine labour relations policy variables representing legislation in eleven canadian jurisdictions is estimated using logit analysis of 3 347 individual collective agreements mandatory strike votes compulsory dues check off and compulsory conciliation boards are associated with significantly lower strike probabilities prohibition of replacement workers and employer initiated strike votes are associated with significantly higher strike probabilities no significant association was found between strike incidence and the length of cooling off period following conciliation and negotiated or automatic reopeners policy impacts are interpreted in a framework emphasizing the influence of asymmetric inforrnation and joint costs on strikes

networks in the modern economy mexican migrants in the u s labor market this paper attempts to identify job networks among mexican migrants in the u s labor market the empirical analysis uses data on migration patterns and labor market outcomes based on a sample of individuals belonging to multiple origin communities in mexico over a long period of time each community s network is measured by the proportion of the sampled individuals who are located at the destination the united states in any year we verify that the same individual is more likely to be employed and to hold a higher paying nonagricultural job when his network is exogenously larger by including individual fixed effects in the employment and occupation regressions and by using rainfall in the origin community as an instrument for the size of the network at the destination

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

are remittances insurance evidence from rainfall shocks in the philippines several facts motivate this study first life in developing countries is prone to many kinds of risk such as crop and income loss due to natural disasters weather insect infestations and fire and civil conflict second international migration and remittance flows are substantial and growing between 1965 and 2000 individuals living outside their country of birth grew from 2 2 to 2 9 percent of the world population totaling 175 million people in 2000 the remittances that these migrants send to their countries of origin are an important but poorly understood type of international financial flow this article examines a mechanism for coping with shocks ex post on which previous micro level studies have not focused remittances from family members overseas at the international level it is commonly posited that remittance flows from overseas buffer economic shocks in migrants home countries but there have been relatively few empirical tests of this claim with micro level household data related research on the role of domestic migration in pooling risk within extended families includes lucas and stark 1985 rosenzweig and stark 1989 and paulson 2000

leontief versus ghoshian price and quantity models the classical demand driven input output model dates back to leontief 24 25 its economically complete opposite the so called supply driven input output model was developed almost forty years ago by ghosh 16 whereas its first application came more than ten years later by augustinovics 1 followed by giarratani 18 the first theoretical reservations were formulated another ten years later by giarratani 19 and oosterhaven 31 140 1 despite these reservations the model came more or less en vogue in the 1980s several applications appeared at best paying only lip service to this earlier critique 10 5 moreover without much reservations the model also entered the major input output textbook 28 317 22 while uncritical generalizations and reiterations appeared in the theoretical literature 8 3 9 then a heavy discussion about the economic underpinning of the supply driven quantity model was initiated by oosterhaven 33 36 21 34 with that debate the enthusiasm to perform downright applications of the supply driven model seems to have diminished literally in the footnotes of that debate the non existence the mathematics and the possible economic interpretation of the dual price version of the supply driven model was discussed 33 34 independently of this discussion davar 9 presented the dual model in extension but did not discuss the economic plausibility of the underlying economic assumptions nor their implications in view of the misinterpretations and misuse of the quantity version of the supply driven model this contribution aims at an early evaluation of its price version that is as complete and as balanced as possible it is well known that the dual version of the regular input output model is used to simulate cost push inflationary processes 26 188 201 7 246 other applications relate to for instance the price effects of pollution abatement 17 effects of rising energy cost 29 and energy price effects in multiregional or in extended interregional models 35 32 of course this dual price version of the leontief model is based on the same stringent standard assumptions of the quantity version and on some heavy additional assumptions that are made for the price version 37 naturally the potential use of the dual of the supply driven model lies in the simulation of demand pull inflationary processes as opposed to the cost push applications of the dual leontief model hence part of our evaluation will be directed toward the question whether such applications are justified from an economic point of view or not our discussion will start in the next section with a brief summary of the leontief quantity and

remittances and the brain drain revisited the microdata show that more educated migrants remit more two of the most salient trends in migration and development over the last two decades are the large rise in remittances and in the flow of skilled migrants however recent literature based on cross country regressions has claimed that more educated migrants remit less leading to concerns that further increases in skilled migration will impede remittance growth micro data from surveys of immigrants in 11 major destination countries are used to revisit the relationship between education and remitting behavior the data show a mixed pattern between education and the likelihood of remitting and a strong positive relationship between education and amount remitted intensive margin conditional on remitting at all extensive margin combining these intensive and extensive margins yields an overall positive effect of education on the amount remitted for the pooled sample with heterogeneous results across destinations the micro data allow investigation of why the more educated remit more showing that the higher income earned by migrants rather than family characteristics explains much of the higher remittances migration brain drain and education

remittances and the brain drain do more skilled migrants remit more in most destination countries immigration policies are tilted more and more in favor of skilled individuals whether this shift hurts economic prospects in sending countries as argued by the traditional brain drain literature is somewhat controversial the most recent literature focuses on the link between skilled outmigration and educational achievements in the home country this article emphasizes a different channel it considers the argument that skilled migrants raise economic welfare at home by sending a relatively larger flow of remittances while skilled migrants typically earn more and so might be expected to remit more they are also likely to spend more time abroad and to reunite with their close family in the host country these second two factors should be associated with a smaller propensity to remit thus the sign of the impact of the brain drain on total remittances is an empirical question a simple model has been developed showing that skilled migrants may indeed have a lower propensity to remit from a given flow of earnings an empirical equation of remittances is estimated as a measure of the brain drain in developing countries using the docquier and marfouk 2004 data set evidence is found that the brain drain is associated with a smaller propensity to remit

a two stage econometric method for the estimation of carbon multipliers with rectangular supply and use tables abstract the supply use based econometric sube approach was proposed to calculate stochastic input output multipliers from rectangular supply use tables under the product technology assumption however the resulting total use of direct requirements stimulated by final demand be they carbon emissions labor etc may differ from the actual total use of direct requirements to solve this problem we propose in this paper a two stage sube approach which takes as prior the initially estimated sube multipliers and obtains a posterior set of two stage sube multipliers by constrained least squares minimization we illustrate the results with an empirical application for carbon emissions in the portuguese economy in 2005

learning in sequential wage negotiations theory and evidence when union firm pairs bargain sequentially and when unobserved components of firms abilities to pay are subject to correlated shocks unions that bargain later in a sequence can acquire valuable information by observing previous bargaining outcomes in their industry we derive the implications of this kind of learning in an asymmetric information model of wage negotiations and argue that the most robust implication is a lower incidence of strikes among followers than leaders in wage negotiations considerable empirical support for this implication is found in a long panel of canadian contract negotiations

the holdout problem and urban sprawl experimental evidence abstract conventional wisdom as well as economic theory suggests it is more costly to reassemble fragmented land due to transactions costs and strategic bargaining costs both costs are expected to increase with the number of sellers inefficient allocation of land resources may result including property entropy parisi 2002 urban sprawl miceli and sirmans 2007 and deteriorating inner cities given the difficulty of observing actual values attached by buyers and sellers to land little empirical evidence exists to support the conventional wisdom and theoretical work we use experimental methods to examine transactions costs and strategic bargaining costs in a land assembly market game with one buyer 1 4 sellers and complementary exchanges the buyer s final earnings vary inversely with the number of sellers ceteris paribus indicating an incentive to purchase consolidated land delay costs reduce holdout but result in lower payoffs for both buyers and sellers competition between sellers reduces holdout and the buyer s total purchase price
