a dual definition for the factor content of trade and its effect on factor rewards in us manufacturing sector we introduce a dual definition of the factor content of trade fct using the concept of the equivalent autarky equilibrium estimating a symmetric normalized quadratic revenue function for the u s manufacturing sector between 1965 and 1991 we find that the fct for capital is positive while the fct for skilled and unskilled labor is negative suggesting that the leontief paradox is not present then the growth rate of the factor rewards is decomposed to the fct endowments and technological change effects we find that technological change is the most important determinant in explaining wage inequality between skilled and unskilled labor

spoilt for choice multinational corporations and the geography of international production this paper questions the view that foreign direct investment fdi is producing an integrated world production and trading system although multinational firms have a greater choice of locations than in the past their recent investments abroad have taken place within a regional rather than global framework the upsurge of fdi flows from north to south has been attracted by just a handful of fast growing developing countries the paper disputes the claim that the road to development is for poor countries to attract fdi on the scale observed in such countries as malaysia this claim involves a fallacy of composition while fdi can make a valuable contribution most countries will have to rely mainly on their own resources and indigenous producers the paper argues that current proposals for a multilateral agreement on investment neglect both the regional aspects of integration and the need of poorer countries to promote their domestic supply capabilities conflicts of interest which are ignored in the current rhetoric suggest the continuing relevance of a strategic policy approach to international production copyright 1998 by oxford university press

income inequality capitalism and ethno linguistic fractionalization we examine the relationship between capitalism and income inequality for a large sample of countries using an adjusted economic freedom index as proxy for capitalism our results suggest that there is no robust relationship between economic freedom and gini coefficients based on gross income subsequently we analyze the relationship between income redistribution and ethno linguistic fractionalization we find that the impact of ethno linguistic fractionalization on income redistribution is conditional on the level of economic freedom countries that have a high degree of fractionalization redistribute income less while capitalist countries that have a low degree of fractionalization redistribute income more

a note of the theory of international transfers abstract if each of n trading countries supplies each of several international public consumption goods then sufficiently small international transfers have no effect on the consumption production or welfare of any country

co2 emissions of international freight transport and offshoring measurement and allocation abstract the growing offshoring process is the result of the fragmentation of production processes and the creation of global supply chains this process has increased final and intermediate imports but also the distance that goods travel in different stages until they reach the final consumer as well as the requirements of transport per unit of output and the volume of co 2 emissions generated in transporting them nowadays there is no generally accepted criterion for international transport pollution allocation no single country has the responsibility for emissions of international bunkers provided by ipcc in this paper we propose a new methodology for quantifying by sector the impact of international freight transport on total pollution and assigning responsibility to consumers this methodology considers the distance and the means of transport as key elements and uses input output methodology we apply this to the spanish economy combining data from input output tables import data and co 2 emission data the results show that the proportion of total co 2 emissions accounted for by emissions from international freight transportation allocated via the consumer criterion increase up to 4 16 between 1995 and 2000 as expected the industries where this offshoring process is more intense show the greatest increases in carbon emissions related to international transport these emissions are significantly higher than emissions embodied in domestic inputs in some of those industries where international fragmentation of production is relevant and increasing

neutrality and the private provision of public goods with incomplete information abstract in this paper we introduce incomplete information about income into a standard model of private provision of public goods generally one obtains neutrality results similar in nature to those obtained in the complete information model however with incomplete information several additional difficulties exist in attaining neutrality for neutrality to hold i positive contributions have to be made by all individual types ii any redistribution of income must not convey information to the individuals and iii any redistribution must not depreciate the private information individuals have

claim timing and ex post adverse selection many health care treatments are not urgent and may be delayed if patients so choose because insurance coverage is typically determined by the treatment date individuals may have incentives to strategically delay treatments to minimize out of pocket costs the strategic delay of treatment a particular form of moral hazard can be an important source of subsequent adverse selection in which ex ante identical individuals select insurance coverage based on their differing accumulation of previously delayed treatments this article investigates these forces empirically in the context of the missing market for dental insurance using rich claim level data my analysis reveals that approximately 40 of individuals strategically delay dental treatments when incentivized to do so and this flexibility in delaying treatment can explain why the market for dental insurance has largely unraveled more generally the counterfactual analysis suggests features such as open enrolment periods and contracting on pre existing conditions may be helpful tools in overcoming adverse selection in insurance contexts where the timing of uncertainty is not contractible

job market signaling and returns to education we compare two partially separating equilibria in a job market signaling model with unproductive education we find that in one of the two equilibria the fraction of the population with a threshold education level is higher even though the cost of education is higher moreover compared to the other equilibrium the population faces a higher threshold education level yet the educated attain lower wages the reason for this result is that the gross return to education can be higher despite the higher cost of education and a higher threshold

robust determinants of income inequality while economic theory suggests a wide range of potential determinants of income inequality there is little consensus regarding the most relevant ones such a lack of consensus reflects to an important extent the impact of model uncertainty using model averaging techniques specifically wals weighted average least squares to get at a robust set of determinants our results underscore the multiplicity of factors behind rising national level inequalities in the cross section the level of development and demographics as well as unemployment and globalization seem to be key drivers trade and financial globalization have asymmetric effects with trade integration associated with lower inequality and financial globalization with higher inequality financial deregulation and technological change seem to be important drivers of inequality particularly in advanced economies

adapting the knowledge capital model of the multinational enterprise to trade and investment in business services at some conceptual level trade in goods and services are not that much different however the speed at which trade and foreign investment in services is growing along with the fact that the barriers to these activities are quite different from those for trade in goods prompts us to take a more careful look the paper begins with a general discussion about the various policies and technological constraints that impact foreign trade and the establishment of foreign commercial presence in intermediate business services we then discuss which characteristics an accurate modelling approach must capture following that we develop a model that allows for different regimes of trade and or foreign affiliate production in services using markusen s knowledge capital model simulations show that the pattern of service firm headquarters and office locations can differ considerably depending on whether it is trade investment or both that are either liberalised or become technologically feasible our results find that the welfare and factor price consequences are quite similar across the different scenarios

business cycles with staggered prices and international trade in intermediate inputs abstract international trade in intermediate inputs and increasingly in goods produced at multiple stages of processing has been widely studied in the real trade literature we assess the role of this feature of modern world trade in accounting for some stylized facts about international business cycles our model with staggered prices and trade in intermediates across four stages of processing does well in explaining the observed international correlations in aggregate quantities and it performs much better than a single stage model with no trade in intermediates the model in itself does not provide a full account of the cyclical behavior of the real exchange rate but compared to the single stage model it moves in the right direction

deep integration and production networks an empirical analysis this paper investigates the two way relationship between deep integration and production networks trade we capture deep integration with a set of indices constructed in terms of policy areas covered in preferential trade agreements we estimate an augmented gravity equation to investigate the impact of deep integration on production networks trade the results show that on average signing deeper agreements increases production networks trade between member countries by almost 12 percentage points in addition the impact of deep integration is higher for trade in automobile parts and information and technology products compared with textile products to analyse whether higher levels of network trade increase the likelihood of signing deeper agreements we follow the literature on the determinants of preferential trade agreements the estimation results show that after taking into account other pta determinants a ten percentage increase in the share of production network trade over total trade increases the depth of an agreement by approximately 6 percentage points in addition the probability of signing deeper agreements is higher for country pairs involved in north south production sharing and for countries belonging to the asia region

globalization interregional and international inequalities abstract this paper examines the impact of globalization on interregional and international inequalities in a setup of two countries and four regions under international mobility of capital in contrast to the literature countries and regions are not required to be symmetric we find that the aforementioned inequalities are closely related to the country size region size the degree of globalization e g capital mobility and trade costs and the level of local infrastructure in particular international trade behaves as a dispersion force when capital is internationally mobile for small countries such that reducing domestic transport costs lowers its interregional inequality but the opposite can be true for large countries or when capital is internationally immobile

globalization and investment in human capital workers are becoming increasingly concerned about the impact that globalization has on their domestic labor market while existing research typically focuses on the effects on labor market outcomes such as wages and employment we examine whether american workers respond to globalization by increasing their investment in human capital specifically we measure the extent to which offshoring and immigration affect enrollment at institutions of higher education the results indicate that both offshoring and immigration increase enrollment at community colleges particularly among older students we conclude that workers in the u s are responding to offshoring and immigration by acquiring the skills necessary to compete in a global economy

measuring globalization of international trade theory and evidence summary measuring globalization requires a standard of perfect international integration as a benchmark that a single world space would reach under conditions of geographic neutrality in international trade we define this standard and present indicators for openness connectedness and integration for each specific economy and for the world economy we apply our indicators to data on trade flows for 59 countries for the 1967 2004 period results show that trade integration is higher than what traditional openness indicators suggest several economies find high levels of integration but the low degree of openness in some large economies jeopardizes the progress of globalization

the incidence of medicare abstract the medicare program transfers nearly 300 billion annually from taxpayers to beneficiaries this paper considers the incidence of such transfers in the context of a life cycle model with uncertainty about future health care expenditures we find the distributional consequences of the medicare program are roughly neutral in dollar terms households living in high income neighborhoods pay more in taxes but they also receive more in benefits these dollar flows however ignore the insurance value of the medicare system given the incomplete insurance coverage of lower income elderly households prior to the medicare program the money metric benefits to lower income groups exceed the dollar flows suggesting that medicare redistributes more than a simple accounting exercise would suggest

is everything neutral in his well known analysis of the national debt robert barro introduced the notion of a dynastic family this notion has since become a standard research tool particularly in the areas of public finance and macroeconomics in this paper we critique the assumptions on which the dynastic model is predicated and argue that this framework is not a suitable abstraction in contexts in which the objective is to analyze the effects of public policies we reach this conclusion by formally considering a world in which each generation consists of a large number of distinct individuals as opposed to one representative individual we point out that family linkages form complex networks in which each individual may belong to many dynastic groupings the resulting proliferation of linkages between families gives rise to a host of neutrality results including the irrelevance of all public redistributions distortionary taxes and prices since these results are not at all descriptive of the real world we conclude

offshoring the nature of tasks and occupational stability empirical evidence for germany using a large administrative data set of individual employment histories for germany this paper studies the relationship between offshoring and the individual risk of leaving the occupation moreover a rich data set on tasks performed in occupations is used to better characterise the sources of worker vulnerability both material and service offshoring are on average not associated with an increase in occupational outflow rates however this association depends on the nature of tasks performed in the occupation higher intensities of interactive and in particular non routine tasks are associated with a larger decrease or a smaller increase in the occupational hazard rate

exchange of cost information in oligopoly when do oligopolists gain by sharing their private information about their costs with one another what are the social welfare effects of such information exchange i study these questions by comparing the oligopolists expected profits under a cost sharing agreement with their expected profits in the bayesian equilibrium that would arise without cost sharing i also analyse the firms decisions to form a trade association to share their cost data under conditions of linear demand and cournot behaviour industrywide information exchange is the unique point in the core of the trade association membership game the exchange of cost data increases expected profits and welfare but reduces expected consumer surplus cost sharing increases efficiency by raising the market shares of lower cost firms and reducing the variability of aggregate output consumer surplus is diminished however because the variance of output is reduced and consumer surplus is a convex function of output

evaluating carbon dioxide emissions in undertaking offshored production tasks the case of china emerging economies like china india and mexico are becoming the world s manufacturing leaders through the engagement in offshoring production activities in achieving this status however they have met with difficult environmental issues this paper features an analysis of industry level panel data to examine the link between different offshoring tasks in china and carbon dioxide emissions through this analysis the environmental effects of offshored production are addressed specifically an input output model is presented thereby quantifying offshored production tasks in china the results show that iron and steel nonferrous metals is and chemicals ch generate the most carbon dioxide during production of processed goods additionally electrical machinery em and general machinery gm generate a higher amount of carbon dioxide during production of parts and components the results also show that those industries characterized by higher energy consumption have higher carbon dioxide co2 emissions induced by offshoring given these results it seems that any solutions geared towards reducing the energy consumption of entire manufacturing industries would be useful furthermore the results of the analyses presented here indicate that china would be responsible for working with developed countries to reduce carbon dioxide emissions through cooperative environmental regulation a globalization perspective is adopted to offer unique insight into the environmental issues faced by china the results of this paper would provide quantified actionable information for formulating practical industrial policies geared towards reducing carbon dioxide leakage

the rise in the disability rolls and the decline in unemployment between 1984 and 2001 the share of nonelderly adults receiving social security disability insurance income di rose by 60 percent to 5 3 million beneficiaries rapid program growth despite improving aggregate health appears to be explained by reduced screening stringency declining demand for less skilled workers and an unforeseen increase in the earnings replacement rate we estimate that the sum of these forces doubled the labor force exit propensity of displaced high school dropouts after 1984 lowering measured u s unemployment by one half a percentage point steady state calculations augur a further 40 percent increase in the rate of di receipt

offshoring tasks and the skill wage pattern the paper investigates the relationship between offshoring wages and the occupational task profile using rich individual level panel data our main results suggest that when only considering within industry changes in offshoring we identify a moderate wage reduction due to offshoring for low skilled workers though wage effects in relation to the task profile of occupations are not estimated with sufficient precision however when allowing for cross industry effects of offshoring i e allowing for labor mobility across industries negative wage effects of offshoring are quite substantial and depend strongly on the task profile of workers occupations a higher degree of interactivity and in particular non routine content effectively shields workers against the negative wage impact of offshoring

a general purpose technology explains the solow paradox and wage inequality we analyze the consequences of a general purpose technology gpt on output productivity and wages of skilled and unskilled workers our endogenous growth model matches three key empirical facts during the 1980s and 1990s an increasing skill premium a fall in the real wages of unskilled workers and a slowing down of economic growth after the introduction of a gpt 2002 elsevier science b v all rights reserved

global value chains a survey of drivers and measures global value chains gvcs emerged as the paradigm for the international organisation of production for most goods and services production is nowadays vertically fragmented across different countries and this reality gave rise to a significant new strand of research in in ternational trade this article starts by discussing the major driving forces of gvcs in recent decades next it surveys the main measures of gvcs accounting for their different scopes and required datasets the artic le highlights the timing of the contributions to the literature signalling their sequential nature and the trend towards more accurate and data demanding indicators

agglomeration opportunism and the organization of production abstract recent economic analysis of outsourcing has emphasized its international dimension in contrast this paper focuses on local outsourcing the paper specifies and solves a model where the organization of production vertically integrated or not and the location of production agglomerated or not are jointly determined the paper shows that agglomeration reduces opportunism a thick market effect and so serves as a substitute for integration this force will lead firms to agglomerate the paper also shows that the normative properties of equilibrium with local outsourcing are not as clear cut as for international outsourcing since local agglomeration is achieved at the cost of congestion local markets may be too thick which would not be the case for an increase in the thickness of a world market finally the many changes in economic and social circumstance that have been labeled globalization do not impact only vertically integrated firms they also impact cities and industry clusters to the extent that agglomeration is a substitute for vertical integration

inequality credit and financial crises in the three decades leading up to the financial crisis of 2008 09 income inequality rose across much of the developed world this has led to a vigorous debate as to whether widening inequality was somehow to blame for the crisis by driving private sector credit booms despite growing interest empirical evidence on an inequality fragility relationship is limited based on a panel analysis of 18 oecd organisation for economic co operation and development countries for the years 1970 2007 this study provides evidence of a positive relationship between income concentration and private sector indebtedness once other traditional drivers are controlled for if confirmed the implications of this result are as follows i the view that the distribution of income is irrelevant to macroeconomic stability as implicit in mainstream approaches needs further investigation and ii in order to make the financial system more robust policy makers should cast the net wider than monetary policy and regulatory reforms and consider the effects of changes to distributive patterns

computerisation and wage dispersion an analytical reinterpretation the rich countries have recently seen a dramatic rise in income inequality all the more surprising because the long term trend had been toward equality this paper examines one of the leading explanations computerisation in the workplace i offer a theory of computers impact on white collar work which goes far toward explaining the timing form and locus of recent labour market changes the theory looks at the bureaucratic and organisational applications of computers that have been first largest and most influential they have two effects on firms demand for labour at different skill levels

dynamic inefficiencies in an employment based health insurance system theory and evidence we investigate the effects of the institutional settings of the us health care system on individuals life cycle medical expenditures health is a form of general human capital labor turnover and labor market frictions prevent an employer employee pair from capturing the entire surplus from investment in an employee s health thus the pair underinvests in health during working years thereby increasing medical expenditures during retirement we provide empirical evidence consistent with the comparative statics predictions of our model using the medical expenditure panel survey meps and the health and retirement study hrs our estimates suggest significant inefficiencies in health investment in the united states

trade liberalization and strategic outsourcing this paper develops a model of strategic outsourcing with trade liberalization in the intermediate product market a domestic firm may choose to purchase a key intermediate good from a more efficient foreign producer who also competes with the domestic firm for a final good this has a strategic effect on competition unlike the outsourcing motivated by cost saving the strategic outsourcing has a collusive effect that could raise the prices of both intermediate and final goods trade liberalization in the intermediate good market has a very different effect compared with trade liberalization in the final good market d 2003 elsevier b v all rights reserved

services offshoring and its impact on productivity and employment evidence from germany 1995 2006 economists have recently recognised services offshoring as an important influence on domestic labour market outcomes services are of particular interest since their significance has grown in terms of both quantity and quality only one and a half decades ago most services were considered non tradable but the emergence and development of new information and communication technologies has made many services internationally tradable the liberalisation of international trade in services trade has further accelerated the volume of services trade our econometric estimations focus on services offshoring by german manufacturing sectors we use revised input output data from 1995 to 2006 we first estimate the impact of services offshoring on labour productivity we then measure the effects of services offshoring on labour demand the results show that services offshoring increased sectoral labour productivity but reduced german manufacturing employment the overall results suggest that labour demand decreased over 1995 2006 because labour reducing productivity and substitution effects dominated labour augmenting scale effects from services offshoring

parcelling virtual carbon in the pollution haven hypothesis the methodology proposed in this paper allows us to parcel the pollution haven hypothesis phh into a bi regional input output framework to analyse whether the specialisation of countries in different stages of production and or in final goods trading generates an increase or a decrease in global emissions as a consequence of international trade we apply the model to the spain china trade relationship as it existed in 2005 finding a phh of 29 667 ktco2 if this trade had not existed so each country had met its demand for intermediate and final goods global emissions would have been reduced by these 29 667 ktco2 of this phh 43 5 corresponds to imports of final goods 32 4 is related to imports of intermediate goods for the last stage of production the remainder 24 1 is caused by global value chains gvc between the countries only 3229 ktco2 of phh emissions are linked to domestic emissions from the sector in which the imports are produced the rest is explained by domestic linkages or successive rounds of domestic production which supports the existence of an indirect phh together with a trade growth in the last years the fall of trade barriers would have implied a transformation of global production chains that have boosted global emissions

economic impacts of new unionization on private sector employers 1984 2001 economic impacts of unionization on employers are difficult to estimate in the absence of large representative data on establishments with union status information estimates are also confounded by selection bias because unions could organize at highly profitable enterprises that are more likely to grow and pay higher wages using multiple establishment level data sets that represent establishments that faced organizing drives in the united states during 1984 1999 this paper uses a regression discontinuity design to estimate the impact of unionization on business survival employment output productivity and wages essentially outcomes for employers where unions barely won the election e g by one vote are compared with those where the unions barely lost the analysis finds small impacts on all outcomes that we examine estimates for wages are close to zero the evidence suggests that at least in recent decades the legal mandate that requires the employer to bargain with a certified union has had little economic impact on employers because unions have been somewhat unsuccessful at securing significant wage gains

spiders and snakes offshoring and agglomeration in the global economy abstract global production sharing is determined by international cost differences and frictions related to the costs of unbundling stages spatially the interaction between these forces depends on engineering details of the production process with two extremes being snakes and spiders snakes are processes whose sequencing is dictated by engineering spiders involve the assembly of parts in no particular order this paper studies spatial unbundling as frictions fall showing that outcomes are very different for snakes and spiders even if they share some features both snakes and spiders have in common a property that lower frictions produce discontinuous location changes and overshooting parts may move against their comparative costs because of proximity benefits and further reductions in frictions lead these parts to be reshored predictions for trade volumes and the number of fragmented stages are quite different in the two cases for spiders a part crosses borders at most twice the value of trade increases monotonically as frictions fall except when the assembler relocates and the direction of parts trade is reversed for snakes the volume of trade and number of endogenously determined stages is bounded only by the fragmentation of the underlying engineering process and lower frictions monotonically increase trade volumes

policy uncertainty and the sequence of entry by japanese firms 1980 1998 we extend the stages model of internationalization to incorporate a sophisticated consideration of temporal and cross national variation in the uncertainty of the policy environment using a sample of 6465 international expansions of 665 japanese manufacturing firms in 49 countries we develop arguments from internationalization and bargaining power perspectives to show how japanese firms manage policy uncertainty in host country environments through the within country sequencing of investments although a distribution to manufacturing entry sequence tends to prevail in countries with low levels of policy uncertainty as uncertainty in the policy environment increases initial entry by distribution is increasingly likely to be eschewed in favor of an initial entry by a joint venture manufacturing plant we suggest that this change in investment sequence occurs as firms shift from an emphasis on developing knowledge about local markets and consumers in low hazards markets to an international expansion strategy in uncertain policy environments that places knowledge development of the policy environment at the forefront of a firm s strategy

the impact of foreign trade on the employment of unskilled u s workers some new evidence this paper explores four empirical relationships reflecting the impact of foreign trade on the employment of unskilled workers i the direct relationship between net exports and embodied education of the corresponding goods ii the changes in domestic prices accompanying changes in net exports iii the relationship between real or potential import competition and defensive measures such as more investment or increasing the skill level of the labor force and iv the relationship between foreign trade and domestic prices none of these exercises suggests that foreign trade has much impact on the employment of less skilled u s workers

service offshoring and firm employment abstract major technological advances have recently spurred a new wave of offshoring in services which used to be non tradable should service workers in developed countries worry about their jobs trade theory has given a nuanced answer to this question suggesting that efficiency gains from offshoring may counteract direct job losses which leaves the predicted net effect ambiguous this paper investigates the employment effects of service offshoring in a newly combined and exceptionally detailed panel dataset covering almost the entire universe of german firms service imports over the years 2001 2013 it exploits firm specific export supply shocks by partner countries and service types as an instrumental variable to find that service offshoring has increased firm employment in line with the canonical trade in tasks model the employment gains are greater in firms with higher initial levels of service offshoring

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

moral hazard and selection among the poor evidence from a randomized experiment not only does economic theory predict high risk individuals to be more likely to purchase insurance but insurance coverage is also thought to crowd out precautionary activities in spite of stark theoretical predictions there is conflicting empirical evidence on adverse selection and evidence on ex ante moral hazard is very scarce using data from the seguro popular experiment in mexico this paper documents patterns of selection on observables into health insurance as well as the existence of non negligible ex ante moral hazard more specifically the findings indicate that i agents in poor self assessed health prior to the intervention have all else equal a higher propensity to take up insurance and ii insurance coverage reduces the demand for self protection in the form of preventive care curiously however individuals do not sort based on objective measures of their health

employment job turnover and trade in producer services uk firm level evidence abstract we provide the first firm level evidence of the impact of the trade in producer services offshoring on the labour market using a new data set from the uk that measures trade in services at the firm level we find no evidence that importing intermediate services is associated with job losses or greater worker turnover using regression to control for observable differences between firms that import service inputs and those that do not we show that firms that start importing intermediate services experience faster employment growth than equivalent firms that do not this seems likely to be the result of positive demand shocks which cause a simultaneous increase in employment output and use of imported service inputs

value added and participation in global value chains the case of spain following koopman wang and wei and using the data and indicators derived from the international input output tables of the world input output database this paper addresses the participation of the spanish economy and its sectors in global value chains gvcs during the period 1995 2011 and its implications for the value added content of trade the analysis reveals the increasing integration of the country in gvcs and the heterogeneity between manufacturing and services in their vertical specialisation and their contribution to value added this paper also explores the link between the use of foreign factors and export performance at the industry level and finds that this type of involvement in gvcs is positively correlated with increases in the domestic value added content of spanish exports

offshoring along the production chain recent contributions on offshoring often assume that firms can freely split their production process into separate steps which can be ranked according to the cost savings from producing abroad we replace this assumption by the notion of a technologically determined sequence of production steps in our model cost savings from offshoring fluctuate along the production chain and moving unfinished goods across borders causes transport costs we show that in such a setting firms may refrain from offshoring even if relocating individual steps would be advantageous conversely small variations in model parameters may lead to a large increase in offshoring activities

outsourcing and the us labour market there is worldwide concern about the vulnerability of the current labour force to displacement by future imported services in the usa some have suggested that as much as one third of the workforce might be vulnerable to such outsourcing however the labour market impacts of this displacement are difficult to assess using purely analytical or statistical approaches in this paper simulation methods are used to understand how sensitive the us economy and labour market are to increases in services imports specifically the scenario examined assumes that the share of imported services in total employment increases from 0 8 per cent to 7 25 per cent over a time horizon in which workers are unable to change occupations in response it is found that all industries increase their use of imported services and their use of the composite input that is comprised of imported services and tradable labour with the exception of legal workers all workers in tradable occupations experience declines in their real wages demand for non tradable occupations labour rises in the industries that expand the most while demand falls in shrinking industries the non tradable occupations that are used intensively in the shrinking industries experience declines in real wages while the real wages rise for workers in non tradable occupations used intensively in the expanding industries

multinational firms acquisitions and job tasks we revisit the question how inward fdi and multinational ownership affect relative labor demand motivated by the recent literature that distinguish between skills and tasks we argue that the impact of multinational and foreign ownership on the demand for labor is better captured by focusing on job tasks rather than education we use swedish matched employer employee data and find that changes of local firms to both foreign and swedish multinationals increase the relative demand for non routine and interactive job tasks in the targeted local firms hence in a high income country both inward and outward fdi have a task upgrading impact on local firms the effect is primarily driven by wage effects leading to increased wage dispersion for workers with different non routine and interactive task intensity we also show that the effect is not the same as skill upgrading since dividing employees by educational attainment does not capture changes in the relative labor demand hence our results suggest a new aspect of the labor market consequences of fdi less

does offshoring of materials and business services affect employment evidence from a small open economy the fear of massive job losses has prompted a fast growing literature on offshoring and its impact on employment in advanced economies this paper examines the situation for belgium it improves the offshoring intensity measure by computing a volume measure of the share of imported intermediates in output and it is among the first to address both materials and business services offshoring to high wage and low wage countries estimations of static and dynamic industry level labour demand equations augmented by offshoring intensities do not reveal a significant impact of either materials or business services offshoring on total employment for belgium between 1995 and 2003

wage fairness in a subcontracted labor market abstract labor market subcontracting is a global phenomenon this paper presents a theory of wage fairness in a subcontracted labor market where workers confront multi party employment relationships and deep wage inequities between regular and subcontractor mediated hires we show that subcontracting derives its appeal from a downward revision of workers fair wage demand when producers delegate employment decisions down the supply chain furthermore subcontracting creates a holdup problem resulting in wages that workers deem unfair along with adverse worker morale consequences in equilibrium these insights reveal the efficiency costs of subcontracting as an employer strategy to redress workers demand for fair wages

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

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

the effect of outward processing trade on wage inequality the hong kong case abstract this study uses time series analysis to investigate the impact of hong kong s increased outward processing trade with the chinese mainland on wage inequality we found a significant positive association between outward processing trade and the wage premium of university graduates over primary school graduates and that over secondary school graduates moreover a standard test showed one way causality from outward processing trade to the widening of skill wage gap furthermore the increase of outward processing trade is found to both increase the pay for well educated people and decrease the pay for less well educated people thereby widening the wage gap

the value of life and the rise in health spending over the past half century americans spent a rising share of total economic resources on health and enjoyed substantially longer lives as a result debate on health policy often focuses on limiting the growth of health spending we investigate an issue central to this debate is the growth of health spending a rational response to changing economic conditions notably the growth of income per person we develop a model based on standard economic assumptions and argue that this is indeed the case standard preferences of the kind used widely in economics to study consumption asset pricing and labor supply imply that health spending is a superior good with an income elasticity well above one as people get richer and consumption rises the marginal utility of consumption falls rapidly spending on health to extend life allows individuals to purchase additional periods of utility the marginal utility of life extension does not decline as a result the optimal composition of total spending shifts toward health and the health share grows along with income in projections based on the quantitative analysis of our model the optimal health share of spending seems likely to exceed 30 percent by the middle of the century

skilled unskilled wage inequality and urban unemployment i introduction an extensive body of literature has looked at possible effects of trade liberalization on the labor market in the north the effects on the labor market in the south have not drawn as much attention conventional wisdom associated with the stolper samuelson theorem predicts a gradual reduction of skilled unskilled wage inequality in the south however recent studies on latin american countries exhibit conflicting patterns wood 1997 summarizes the empirical findings citing a series of articles by robbins 1995a 1995b 1996a 1996b that convincingly demonstrate that latin america has experienced an increasing wage gap between the skilled and the unskilled following a more open trade and investment regime while globalization induced changes in production patterns and the consequent increase in the demand for skilled labor relative to unskilled labor has often been cited as the root cause of wage inequality there has been no general agreement over the possible source of such increased demand for skilled labor the debate among economists on this has followed two broad paths one relying on technological changes and the other on trade and investment while technological change may have played a key role in the widening wage gap in the industrialized countries there is strong evidence robbins 1994a 1994b 1995a 1995b 1996a 1996b robbins and zveglich 1995 wood 1997 indicating the dominant influence of trade and investment on wage inequality in the developing economies the implications of a more open trade and investment regime need to be analyzed in terms of frameworks that explicitly take into account the structural features of labor markets in the south one of the key structural differences between the north and the south is that the south experiences a pronounced rural urban migration in the presence of urban unemployment basu 1997 ray 1998 the goal of our paper was to capture this feature within the structure of a simple general equilibrium model in an effort to understand the effect of fragmentation on the skilled unskilled wage differential and employment in the south the rest of the paper is organized as follows the next section places this paper in the context of the relevant literature section iii describes the general equilibrium model with the possibility of fragmentation and unemployment section iv compares and contrasts the impact of trade and endowment on the skilled unskilled wage gap and employment with and without fragmentation section v concludes ii context the motivation of this paper stems from our view that the southern experience does not necessarily contradict conventional wisdom as has been claimed in wood 1997 but points to the need for parsimonious yet meaningful modifications of the structure of general equilibrium models from which the wisdom is derived to properly reflect the salient structural features of the south on the one hand production fragmentation has become an important facet of globalization in modern times 1 sharp declines in transportation and communication costs have encouraged this process of slicing the value chain that is evident in international trade data this has been sustained by various regional integration agreements that have reduced the barriers to international trade and investment as well as important technical innovations in telecommunications and information technology that have facilitated the coordination of international production networks this advanced stage in the international division of the chain of production has brought a fundamental change in the nature of international trade as goods increasingly cross multiple national borders while they are in process several authors such as jones kierzkowski and lurong 2005 wan 2005 long 2005 jones and kierzkowski 1998 jones and marjit 2001 arndt 1998 feenstra 1998 harris 1998 hummels rapoport and yi 1998 feenstra and hanson 1996b and dixit and grossman 1982 have analyzed the role of fragmentation in world trade

what did medicare do the initial impact of medicare on mortality and out of pocket medical spending abstract we study the impact of the introduction of one of the major pillars of the social insurance system in the united states the introduction of medicare in 1965 our results suggest that in its first 10 years the establishment of universal health insurance for the elderly had no discernible impact on elderly mortality however we find a substantial reduction in the elderly s exposure to out of pocket medical expenditure risk specifically we estimate that the introduction of medicare was associated with a 40 decline in out of pocket spending for the top quartile of the out of pocket spending distribution a stylized expected utility framework suggests that the welfare gains from such reductions in risk exposure alone may be sufficient to cover almost two fifths of the costs of medicare these findings underscore the importance of considering the direct insurance benefits from public health insurance programs in addition to any indirect benefits from an effect on health

globalization outsourcing and wage inequality there is considerable debate over whether international trade has contributed to the declining economic fortunes of less skilled workers one issue that has become lost in the current discussion is how firms respond to import competition and how these responses in turn are transmitted to the labor market in previous work we have argued that outsourcing by which we mean the import of intermediate inputs by domestic firms has contributed to an increase in the relative demand for skilled labor in the united states if firms respond to import competition from low wage countries by moving non skill intensive activities abroad then trade will shift employment towards skilled workers within industries in this paper we extend our previous work by combining new import data from the revised nber trade database with disaggregated data on input purchases from the census of manufactures we construct industry by industry estimates of outsourcing for the period 1972 1990 and reexamine whether outsourcing has contributed to an increase in relative demand for skilled labor our main finding is that outsourcing can account for 31 51 of the increase in the relative demand for skilled labor that occurred in u s manufacturing industries during the 1980s compared to our previous estimate of 15 33 this abstract was borrowed from another version of this item

foreign direct investment and the relative wage in a developing economy abstract this paper examines the issue of the effect of foreign direct investment on the relative wage in the context of a developing economy recognizing that competing domestic entrepreneurs are potentially skilled workers foreign investment in skilled labor intensive sectors is shown to lower the relative wage moreover a general lump sum subsidy to foreign and domestic firms is shown to lower aggregate welfare whereas a discriminatory subsidy only to foreign firms may raise welfare

the effect of medicare part d on pharmaceutical prices and utilization prescription drug expenditures represent the most rapidly growing component of health care spending increasing from 5 percent of health care spending in 1980 to more than 10 percent by 2005 centers for medicare and medicaid services cms 2007a further almost 60 percent of all prescriptions in the united states are filled for beneficiaries of medicare medicaid and other government programs rapid innovation in new pharmaceuticals has contributed substantially to quality of life and longevity in the us frank lichtenberg 1996 these facts combined indicate that government procurement schemes are critical both in determining government expenditure on pharmaceuticals and in stimulating innovation of new treatments in this paper we show that the institutions and mechanisms used by the government to pur chase prescription drugs can strongly affect market outcomes by institutions we have in mind large buyer groups structured incentives for patients to consume certain products and the devel opment and use of formularies a formulary is a mechanism that allows a buyer to identify a therapeutically similar treatment as a viable substitute for a patented treatment and to create price competition due to the ability to substitute away from the more expensive product when bargaining with the seller of a patented product the ability to shift demand to a substitute drug is a powerful negotiating tool our paper provides evidence for what we consider a surprising outcome in the case of the new prescription drug program for medicare enrollees moving consumers from cash paying status to membership in an insured group lowers optimal prices for branded prescription drugs below what they otherwise would be this is surprising because the standard effect of insurance is to create inelastic demand and therefore elicit higher prices from a seller with market power duggan and scott morton 2006 however the insurers that we study bundle insurance with a formulary and other mechanisms to create elastic demand an individual consumer typically does not know which drugs are acceptable therapeutic substitutes the consumer s physician typi cally has poor knowledge of prices especially negotiated prices and any one consumer is too small a share of demand to negotiate with a pharmaceutical company a prescription drug plan can potentially surmount all three hurdles our evidence leads us to conclude that the formulary and other mechanisms perform the spe cial role of allowing buyers to move market share among drugs with patent protection thereby raising cross price elasticities and lowering purchase prices or reducing price increases for branded drugs this result contrasts with the common intuition that an uninsured consumer

auditing and competitive bidding in the public sector abstract this paper investigates the impact of a ministry s budget size on the choice between auditing a niskanen bureau and employing competitive bidding in the provision of a publicly funded good the ministry s marginal expected payoff increases fastest with budget size for auctioning as opposed to auditing however the ministry is shown to switch from a purely public provision to a competitive provision as the budget size increases even if expected fixed costs favor the audit the study contributes to the literature by extending the niskanen framework and by endogenizing the institutional arrangements for the provision of public sector goods

innovation and wage effects of international outsourcing abstract we investigate the effects of increased outsourcing of production to a low wage country such international outsourcing lowers the marginal cost of production and thus increases profits creating greater incentives for innovation a reduction in the resource requirement in adapting technology relative to improving products or an expansion in the portion of production that can be outsourced generates a greater extent of international outsourcing a lower relative wage and a faster rate of innovation an increase in production taxes in the north production subsidies in the south or a subsidy to adapting technologies has similar effects

international fragmentation boon or bane for domestic employment abstract in this paper we introduce the fairness approach to efficiency wages into a standard model of international fragmentation this gives us a theoretical framework in which wage inequality and unemployment rates are co determined and therefore the public concern can be addressed that international fragmentation and outsourcing to low wage countries lead to domestic job losses we develop a novel diagrammatic tool to illustrate the main labour market effects of international fragmentation we also explore how preferences for fair wages and the size of unemployment benefits govern the employment effects of outsourcing and critically assess the role of political intervention that aims to reduce unemployment benefits under internationally fragmented production

service offshoring and productivity evidence from the us the practice of sourcing service inputs from overseas suppliers has been growing in response to new technologies that have made it possible to trade in some business and computing services that were previously considered non tradable this paper estimates the effects of offshoring on productivity in us manufacturing industries between 1992 and 2000 it finds that service offshoring has a significant positive effect on productivity in the united states accounting for around 10 per cent of labour productivity growth during this period offshoring material inputs also have a positive effect on productivity but the magnitude is smaller accounting for approximately 5 per cent of productivity growth

employability miles and worker employability awareness this article studies the use and impact of a employability miles voucher scheme these vouchers could be used for participation in a restricted number of training courses which all aim to stimulate employees to develop a more active attitude towards their own employability using data from two surveys of one firm s workforce we find that voucher use is related to various personality traits and personal characteristics in particular a worker s ambition goal setting and education level are positively related to voucher use in addition workers with longer tenure spend their vouchers more often conversely workers with a more positive self image as well as those who are negatively reciprocal spend their vouchers less often the negative relation between voucher use and negative reciprocity suggests that workers who are more negatively reciprocal perceive the voucher as an hr tool for outplacement further we find that voucher use positively affects worker employability awareness and willingness t

bidding for a group specific public good prize abstract we examine the equilibrium effort levels of individual players and groups in a contest in which two groups compete with each other to win a group specific public good prize the players choose their effort levels simultaneously and independently and the winning group is determined by the selection rule of all pay auctions we first prove nonexistence of a pure strategy nash equilibrium and then construct a mixed strategy nash equilibrium at the nash equilibrium the only active player in each group is a player whose valuation for the prize is the highest in that group all the other players expend zero effort and the equilibrium effort levels depend solely on two values the highest valuation for the prize in each group

how social security and medicare affect retirement behavior in a world of incomplete markets this paper provides an empirical analysis of how the u s social security and medicare insurance system affect the labor supply of older males in the presence of incomplete markets for loans annuities and health insurance we estimate a detailed dynamic programming dp model of the joint labor supply and social security acceptance decision focusing on a sample of males in the low to middle income brackets whose only pension is social security the dp model delivers a rich set of predictions about the dynamics of retirement behavior and comparisons of actual vs predicted behavior show that the dp model is able to account for wide variety of phenomena observed in the data including the pronounced peaks in the distribution of retirement ages at 62 and 65 the ages of early and normal eligibility for social security benefits respectively we identify a significant fraction of health insurance constrained individuals who have no form of retiree health insurance other than medicare and who can only obtain fairly priced private health insurance via their employer s group health plan the combination of significant individual risk aversion and a long tailed pareto distribution of health care expenditures implies that there is a significant security value for these individuals to remain employed until they are eligible for medicare coverage at age 65 overall our model suggests that a number of heretofore puzzling aspects of retirement behavior can be viewed as artifacts of particular details of the social security rules whose incentive effects are especially strong for lower income individuals and those who do not have access to fairly priced loans annuities and health insurance

intellectual property rights product complexity and the organization of multinational firms this paper studies how the intellectual property right ipr regime in destination countries influences the way multinationals structure the international organization of their production in particular we explore how multinationals divide tasks of dierent complexities across countries with dierent levels of ipr protection the analysis studies the decision of firms between procurement from related parties and outsourcing to independents suppliers at the product level it also breaks down outsourcing into two types by distinguishing whether or not they involve technology sharing between the two parties we combine data from a french firm level survey on the mode choice for each transaction with a newly developed complexity measure at the product level our results confirm that firms are generally reluctant to source highly complex goods from outside firm boundaries by studying the interaction between product complexity and the ipr protection we obtain that i for technology sharing outsourcing iprs promote outsourcing of more complex goods to a destination country by guaranteeing the protection of their technology ii for non technology related outsourcing iprs attract the outsourcing of less complex products that are more prone to reverse engineering and simpler to decodify and imitate

world country and sector factors in international business cycles do sector specific factors common to all countries play an important role in explaining business cycle co movement we address this question by analyzing international co movements of value added va growth in a multi sector dynamic factor model the model contains a world factor country specific factors sector specific factors and idiosyncratic components we estimate the model using bayesian methods for 30 disaggregated sectors in the g7 economies for the 1974 2004 period our findings show that although there is a substantial role for sector specific factors fluctuations are dominated by country factors the world factor appears to play a minimal role because when using aggregate data the world factor captures both the factor common to all countries and industries and the factor common to the same industry across countries we then examine how these factors evolved as globalization deepened over the past two decades our results suggest that business cycles at a disaggregate level have not become more synchronized internationally this is mainly driven by a substantial fall in the volatility of world shocks during the globalization period rather than a lower sensitivity of sectoral growth to world factors our results also reveal that world factors appear to be more important for industries with a higher level of international vertical integration

the impact of nearly universal insurance coverage on health care utilization evidence from medicare the onset of medicare eligibility at age 65 leads to sharp changes in the health insurance coverage of the u s population these changes lead to increases in the use of medical services with a pattern of gains across socioeconomic groups that varies by type of service while routine doctor visits increase more for groups that previously lacked insurance hospital admissions for relatively expensive procedures like bypass surgery and joint replacement increase more for previously insured groups that are more likely to have supplementary coverage after 65 reflecting the relative generosity of their combined insurance package under medicare
