addressing leakage in the eu ets border adjustment or output based allocation the eu ets has been criticised for threatening the competitiveness of european industry and generating carbon leakage i e increasing foreign greenhouse gas emissions two main options have been put forward to tackle these concerns border adjustments and output based allocation i e allocation of free allowances in proportion to current production we compare various configurations of these two options as well as a scenario with full auctioning and no border adjustment against this background we develop a model of the main sectors covered by the eu ets electricity steel cement and aluminium we conclude that the most efficient way to tackle leakage is auctioning with border adjustment which generally induces a negative leakage a spillover this holds even if the border adjustment does not include indirect emissions if it is based on eu rather than foreign specific emissions or for some values of the parameters if it covers only imports another relatively efficient policy is to combine auctioning in the electricity sector and output based allocation in exposed industries especially if free allowances are given both for direct and indirect emissions i e those generated by the generation of the electricity consumed although output based allocation is generally less effective than border adjustment to tackle leakage it is more effective to mitigate production losses in the sectors affected by the ets which may ease climate policy adoption c 2011 elsevier b v all rights reserved

carbon leakage and capacity based allocations is the eu right competitiveness and carbon leakage are major concerns for the design of co2 emissions permits markets in the absence of a global carbon tax and of border carbon adjustments output based allocation is a third best solution and is actually implemented australia california new zealand the eu has followed a different route free allowances are allocated to existing or new capacities in proportion to a benchmark independent of actual production this paper compares these two schemes in a formal setting and shows that the optimal one is in fact a combination of both schemes or output based allocation alone if uncertainty is limited a key assumption of our analysis is that the short term import pressure depends both on the existing capacities and the level of demand which is typical in capital intensive and internationally traded sectors a calibration of the model is used to discuss the eu scheme for the cement sector in the third phase of the eu ets 2013 2020 this allows for a quantification of various policies in terms of welfare investment production company profits public revenues and leakage

frontiers of climate change economics the economics of climate change is an active field of research the contributions to a special issue are put in context of the literature and it is suggested that second best issues such as carbon leakage and the green paradox need to be complemented with a political economy analysis of why certain instruments are politically infeasible and with intra and intergenerational analyses of the impact of climate policy a case is also made for more empirical work on the gradual and catastrophic damages of global warming

should a carbon tax be differentiated across sectors abstract if some but not all countries are cooperating to reduce co2 emissions one could make the following argument a high carbon tax for carbon intensive tradeable sectors in the cooperating countries will reduce the production of goods from these sectors and therefore co2 emissions in the cooperating countries however this will to a large extent be counteracted by increased production of such goods in the countries that have no climate policy and since it is only total co2 emissions from all countries that are relevant for the climate there is no point in a policy that simply relocates co2 emissions from the cooperating countries to the countries that have no climate policy according to this line of reasoning carbon intensive tradeable sectors should thus face a lower carbon tax than other sectors of the economy this paper shows that a carbon tax should not be differentiated across sectors in the economy provided one can use import and export tariffs on all traded goods it is also shown that such a differentiation of carbon taxes is optimal for the cooperating countries if they are prevented from using tariffs on the traded goods however informational or political factors constraining the use of tariffs are likely also to constrain the possibility of differentiating carbon taxes between sectors

vertical targeting and leakage in carbon policy in this paper we examine the intersection between two important aspects of climate policy design the first is the point of regulation should it be placed on pollution sources carbon rich inputs or consumers this issue of upstream versus downstream regulation is one that we will refer to as vertical targeting the second aspect concerns the external effects of a local climate policy leakage occurs when par tial regulation results in an increase in emissions in unregulated parts of the economy this paper examines how regulators choice of upstream versus downstream environmental regulation affects emissions in other countries with lax environmental regulation these two elements of climate policy are closely related in many contexts the selection of the point of regulation in the vertical chain is influenced if not driven by concerns over extrajurisdictional impacts given the global nature of the pollutant regulators in any specific jurisdiction need to be mindful of how local limits will effect global emissions regions imposing greenhouse gas restrictions may consume more than they produce of carbon intensive goods such as gasoline or cement in such cases regulations imposed on consumers can reach upstream to producers located outside the regulated areas for example by raising the cost of consuming carbon intensive electricity in california regulators in that state hope to reduce the combustion of coal in other regions of the western united states it is important to recognize that vertical tar geting is but one mechanism through which regulators can combat leakage much academic research and legislation has focused on the legal and economic merits of border adjustments such as import tariffs based on carbon content

does economic structure determine financial structure abstract in this paper we examine the relationship between the structure of the real economy and a country s financial system we consider whether the development of the real economic structure can predict the direction of evolution of a country s financial structure using data for 108 countries we find a significant relationship between real economic structure and financial structure next we exploit shocks to the economies in india finland and sweden and south korea and show that changes in the economic structure of a country influence the evolution of its financial system this suggests that financial institutions and capital markets change in response to the structure of industries

central bank transparency and cross border banking abstract we analyze the effect of central bank transparency on cross border bank activities based on a panel gravity model for cross border bank claims for 21 home and 47 destination countries from 1998 to 2010 we find strong empirical evidence that a rise in central bank transparency in the destination country on average increases cross border claims using interaction models we find that the positive effect of central bank transparency on cross border claims is only significant if the central bank is politically independent and operates in a stable economic environment central bank transparency and credibility are thus considered complements by banks investing abroad

measures to enhance the effectiveness of international climate agreements the case of border carbon adjustments abstract actions on climate change which are not supported by all countries are not very effective however full participation in a global climate treaty with meaningful emission reductions is difficult to achieve the non excludability of the public good mitigation provides an incentive to abstain from global action moreover carbon leakage renders it unattractive to join a treaty without full participation we study whether and under which conditions border carbon adjustments bcas can mitigate free riding and reduce carbon leakage in a simple strategic trade model we show that bcas can lead to large stable climate agreements including full participation associated with large global welfare gains if treaties do not restrict membership open membership as this is typical for environmental agreements we caution against restricting accession to treaties exclusive membership as this is typical for trade agreements which may serve individual but not global interests

mitigation of adverse effects on competitiveness and leakage of unilateral eu climate policy an assessment of policy instruments the european union eu has developed a strategy to mitigate climate change by cutting greenhouse gas ghg emissions and fostering low carbon technologies however the risk of implementing unilateral policies is that distortive effects are generated at the global scale affecting world energy prices international competitiveness and the geographical allocation of carbon intensive production processes using a dynamic cge model we assess the rate of carbon leakage and adverse impacts on competitiveness in a number of scenarios over the period 2010 2050 according to the model results we highlight two major issues first in the case of a unilateral eu climate policy carbon leakage and negative effects on competitiveness are quite serious anti leakage measures can only mitigate leakage and adverse economic impacts on competitiveness in a limited way on the contrary an optimality analysis addressing the environmental effectiveness cost effectiveness and political feasibility of alternative policy solutions reveals that the eu long term decarbonisation strategy by investing in energy efficiency and renewable energy might ensure protection of vulnerable manufacturing activities while enhancing the competitiveness of technologically advanced industries

the roles of the state and the market in establishing property rights it is an old saw of the economics profession that markets require a clear assignment of initial entitlements to most resources and well enforced rules of contract governments intent on fostering a market economy should thus make sure to put an effective legal system in place one in which property rights are unambiguous secure and freely alienable even if the state gets some of the initial entitlements wrong it is often added the coase theorem instructs us that the parties if free to contract will correct this by appropriate private agreements the experience of postcommunist countries in eastern europe is a good reminder that economists tend to assume a can opener when one is needed indeed the statement that property and contract rights must be put in place assumes away one of the most interesting and intricate questions concerning economic development the creation of a system of enforceable entitlements to the diverse and complex forms of wealth characteristic of a modern society is itself a process subject to economic laws as i shall argue here it is in fact largely a product of market forces rather than governmental fiat

the changing climate of climate change economics climate change economics is now four decades old much of what it has achieved as a field of academic enquiry can be linked back to issues of integrated assessment modelling this paper shows that the standard approach is going through a major change in scope as of the last five years the conventional focus on determining optimal mitigation paths based on modelling the social cost of carbon is being enlarged to embrace promising new waves of research these are 1 the economics of insurance against catastrophic risks 2 the economics of trade and climate and 3 the economics of climate change adaptation the paper helps to bridge the gap between economics and climate policy by showing that the analytical toolkit of climate change economics has shifted towards more realistic representations of climatic policy

the efficiency cost of protective measures in climate policy despite recent achievements towards a global climate agreement climate action to reduce greenhouse gas emissions remains quite heterogeneous across countries energy intensive and trade exposed eite industries in industrialized countries are concerned on stringent domestic emission pricing that puts them at a competitive disadvantage against producers of similar goods in other countries with more lenient emission regulation this paper focuses on climate policy design in the united states of america us and compares the economic implications of four alternative protective measures for us eite industries i output based rebates ii exemptions from emission pricing iii energy intensity standards and iv carbon intensity standards using a large scale computable general equilibrium model we quantify how these protective measures affect competitiveness of us eite industries we find that protective measures can improve common trade related competitiveness indicators such as revealed comparative advantage or relative world trade shares but at the same time may lead to a decline in the output value for eite industries because of negative income effects the economy wide cost of emission abatement under protective measures increase as compared to uniform emission pricing stand alone such that the gains of protective measures for eite exports may be more than compensated through losses in domestic eite demand

home bias in global bond and equity markets the role of real exchange rate volatility abstract this paper focuses on the role of real exchange rate volatility as a driver of portfolio home bias and in particular as an explanation for differences in home bias across financial assets we present a markowitz type portfolio selection model in which real exchange rate volatility induces a bias towards domestic financial assets as well as a stronger home bias for assets with low local currency return volatility we find empirical support in favour of this hypothesis for a broad set of industrialized and emerging market countries not only is real exchange rate volatility an important factor behind bilateral portfolio home bias but we find that a reduction of monthly real exchange rate volatility from its sample mean to zero reduces bond home bias by up to 60 percentage points while it reduces equity home bias by only 20 percentage points

the role of trade and competitiveness measures in us climate policy efforts of the 111th us congress to pass comprehensive climate change legislation although unsuccessful provide insights into the challenges of reaching political agreement on a package for reducing greenhouse gas ghg emissions chief among legislators concerns is the economic burden on their constituents their household energy bills and particularly their jobs perhaps the most vocal interests in the climate debate are the energy intensive manufacturing sectors they argue that the increased costs of carbon pricing will harm their ability to compete in international markets and that trading partners lack of comparable regulation would shift emissions abroad carbon leakage eroding the environmental benefits the salience of those arguments is under scored by statements by senators from industrial states in 2008 ten democratic senators laid out the principles that final legislation should address cost containment relief for working families technology investment equitable treatment of states and prominently enhanced safeguards to ensure a truly equitable and effective global effort that minimizes harm to the us economy and protects american jobs 1

what drives international financial flows politics institutions and other determinants abstract this paper uses a large panel of financial flow data from banks to assess how institutions affect international lending first employing a time varying composite institutional quality index in a fixed effects framework the paper shows that institutional improvements are followed by significant increases in international finance second cross sectional models also show a strong effect of initial levels of institutional quality on future bank lending third instrumental variable estimates further show that the historically predetermined component of institutional development is also a significant correlate of international bank inflows the results thus suggest that institutional underdeveloped can explain a significant part of lucas lucas robert e 1990 why doesn t capital flow from rich to poor countries american economic review papers and proceedings 80 2 92 96 1990 paradox of why doesn t capital flow from rich to poor countries the analysis also does a first step towards understanding which institutional features affect international banking

border adjustments supplementing nationally determined carbon pricing as agreed on in the paris agreement each country determines its own contribution to combat climate change on a voluntary basis there is no mechanism to force a country to comply with its own nationally determined contributions this bottom up approach builds on unilateral actions and yields a kind of carbon pricing which is not necessarily identical across countries as a consequence these nationally determined climate policies have drawbacks in terms of carbon leakage and loss of competitiveness for firms producing in high carbon price countries to reduce these negative effects border adjustments bas may be appropriate subsequent to more stringent environmental regulation we model a three stage game involving carbon price competition in the first stage the introduction of bas in the second stage and oligopolistic competition between firms in the third stage strategic trade theory suggests that the qualitative results about the optimal ba policy may vary with the underlying type of competition namely bertrand and cournot competition however our results are similar for both types of competition we conclude that bas are suitable for supporting a more stringent environmental policy moreover we find that anticipation of the implementation of bas in the second stage yields higher average carbon prices in the first stage since high carbon price countries increase their carbon prices whereas the other countries partially offset

the great moderation in international capital flows a global phenomenon abstract this paper highlights a recent great moderation in global capital flows characterised by smaller volumes and lower volatility of cross border transactions however there are substantial differences across countries and regions which we analyse by comparing the level of international capital flows observed in 2005 06 immediately prior to the onset of the global financial crisis to the post crisis period of 2013 14 when global flows arguably settled at a new normal we find that since the pre crisis period gross capital inflows recovered more for economies with smaller pre crisis external and internal imbalances lower per capita income improving growth expectations a less severe impact of the global financial crisis and less stringent macroprudential policy on the asset side countries with a more accommodative monetary policy a milder impact of the crisis and oil exporters managed to increase gross capital outflows in the post crisis period

addressing the competitiveness effects of taxing carbon in china domestic tax cuts versus border tax adjustments abstract this study focuses on the international competitiveness effects of levying a carbon tax in china based on a computable general equilibrium model this study analysed the impacts of a carbon tax on different sectors from the aspect of changes in market shares of domestic producers in the domestic markets and changes in exports the effects of different measures including domestic tax cuts and border tax adjustments in alleviating the unfavourable competitiveness impacts were also analysed and compared as were the impacts of different tax schemes on the macro economy sectoral profits and carbon emissions the results show that without any complementary measures a carbon tax would negatively shock the domestic market shares and exports of almost all tradable sectors and the profits of almost all sectors as for cushioning the unfavourable effects the domestic tax cuts are able to ease the negative impacts on the domestic market shares and exports of almost all tradable sectors moreover the unfavourable impacts of domestic tax cuts on both the macro economy and the sectoral profits are obviously smaller than those of the other schemes regardless of the use of the same tax rate or emission reduction amount among the border tax adjustment measures the best performance in general corresponds to the measure purely implementing adjustments on exports

carbon leakage grandfathering as an incentive device to avert firm relocation emission allowances are sometimes distributed for free in an early phase of a cap and trade scheme to reduce adverse effects on the profitability of firms this paper investigates whether grandfathering can also be used to avert the relocation of firms to countries with lower carbon prices we show that under certain conditions relocation can be averted in the long run even if the grandfathering scheme is phased out over time and immediate relocation is profitable in its absence this requires that the permit price triggers sufficient investments into low carbon technologies or abatement capital that create a lock in effect which makes relocation unprofitable

on the effects of unilateral environmental policy on offshoring in multi stage production processes in the last decades supply chains emerged that stretch across many countries this has been explained with decreasing trade and communication costs we extend the literature by analyzing if and how unilateral environmental regulation induces offshoring to unregulated jurisdictions we first apply an analytical partial equilibrium model of a two stage production process that can be distributed between two countries and investigate unilateral emission pricing and its supplementation with border carbon taxes to get a more comprehensive picture we subsequently apply a computable general equilibrium model that includes a better representation of international supply chains we find heterogeneous but mostly positive effects of a unilateral carbon emission reduction by the european union on the degree of vertical specialisation of european industries and explain these differences by heterogeneity in the emission intensity and pre policy vertical specialisation of sectors border taxes are successful in protecting upstream industries but with negative side effects for downstream industries

carbon footprint taxes we analyze whether a carbon consumption tax is logistically feasible we consider a carbon footprint tax cft which would be modeled after a credit method value added tax the basis for the tax would be a product s carbon footprint which includes all of the emissions released during production of the good and its inputs as well as any greenhouse gases latent in the product our analysis suggests that a pure cft requiring the calculation of the carbon footprint of every individual product may be prohibitively costly however a hybrid cft seems economically feasible the hybrid cft would give firms the option to either calculate the carbon footprint of their outputs and have their products taxed based on those footprints or use product class specific default carbon footprints as the tax basis thereby saving on calculation costs because the cft would be levied on all goods consumed domestically the cft would keep domestic firms on an even footing with those producing in countries without active climate policy protecting competitiveness and reducing leakage

european emission trading scheme and competitiveness a case study on the iron and steel industry abstract we quantify the impact of the european emission trading scheme ets on the two dimensions of competitiveness production and profitability for the iron and steel industry among those covered by the scheme this sector is one of the most exposed since it is both highly co 2 intensive and relatively open to international trade we also examine the robustness of these results to various assumptions marginal abatement cost curve trade and demand elasticities as well as pass through rates and updating of allocation rules of which the latter two are scarcely debated we conclude that for this sector competitiveness losses are small we prove this conclusion to be robust hence arguments against tightening the environmental stringency of the ets in phase ii are not justified on grounds of competitiveness loss our systematic sensitivity analysis allows us to identify the important assumptions for each output variable it turns out that pass through rates and updating rules are significant despite being often implicit and least debated in existing analyses

a sectoral approach balancing global efficiency and equity this paper explores the idea that a properly designed sectoral approach could be the answer to two sets of constraints that hinder international agreements on climate change namely a genuine concern from developing countries for economic growth and competitiveness issues from industrialized countries our sectoral approach builds on three premises i cap and trade systems are established in industrialized countries and intensity targets in developing countries ii sectors subject to international trade abide by the rules of the countries in which they trade and iii a fraction of the revenues from permits in industrialized countries go towards carbon mitigation in developing countries we design an economic model that features interactions in three carbon intensive sectors two of which are internationally traded and two countries an industrialized country and a developing country two scenarios are constructed an enhanced sectoral approach which refers to our proposal and a global cap which implements a uniform co2 price we compare the two scenarios in terms of total welfare and equity it is shown that for a minor global welfare loss the enhanced sectoral approach ranks high in terms of equity for emerging countries this approach also eliminates competitiveness and leakage issues

insecurity and the pattern of trade an empirical investigation corruption and imperfect contract enforcement dramatically reduce international trade this paper estimates the reduction using a structural model of import demand in which insecurity acts as a hidden tax on trade we find that inadequate institutions constrain trade as much as tariffs do we also find that omission of indices of institutional quality biases the estimates of typical gravity models obscuring a negative relationship between per capita income and the share of total expenditure devoted to traded goods finally we argue that cross country variation in the effectiveness of institutions and the consequent variation in the prices of traded goods offer a simple explanation for the stylized fact that high income capital abundant countries trade disproportionately with each other

international shock transmission after the lehman brothers collapse evidence from syndicated lending after lehman brothers filed for bankruptcy in september 2008 cross border bank lending contracted sharply to explain the severity and variation in this contraction we analyze detailed data on cross border syndicated lending by 75 banks to 59 countries we find that banks that had to write down sub prime assets refinance large amounts of long term debt and experienced sharp declines in their market to book ratio transmitted these shocks across borders by curtailing their lending abroad while shocked banks differentiated between countries in much the same way as less constrained banks they restricted their lending more to small borrowers

cost effective unilateral climate policy design size matters given the bleak prospects for a global agreement on mitigating climate change pressure for unilateral abatement is increasing a major challenge is emissions leakage border carbon adjustments and output based allocation of emissions allowances can increase effectiveness of unilateral action but introduce distortions of their own we assess antileakage measures as a function of abatement coalition size we first develop a partial equilibrium analytical framework to see how these instruments affect emissions within and outside the coalition we then employ a computable general equilibrium model of international trade and energy use to assess the strategies as the coalition grows we find that full border adjustments rank first in global cost effectiveness followed by import tariffs and output based rebates the differences across measures and their overall appeal decline as the abatement coalition grows in terms of cost the coalition countries prefer border carbon adjustments countries outside the coalition prefer output based rebates

financial regulation and financial system architecture in central europe abstract at the beginning of the transition advice to central european countries with respect to how to set up their financial systems was based on models used in western economies this paper analyzes the experiences to set up a financial system in central europe the experience in the first transition years 1990 1996 with financial system architecture shows that changes are slow but that the central european countries tend to catch up more quickly with the western ones in the case of their banking systems than with respect to their stock markets

financial institutions and markets across countries and over time the updated financial development and structure database this article introduces the updated and expanded version of the financial development and structure database the database includes indicators on the size efficiency and stability of banks nonbank financial institutions and equity and bond markets over 1960 2007 it also contains indicators of financial globalization

output based allocations in pollution markets with uncertainty and self selection we study pollution permit markets in which a fraction of permits are allocated to firms based on their output output based allocations which are receiving increasing attention in the design of carbon markets around the world e g europe california new zealand are shown to be optimal under demand and supply volatility despite the output distortions they may create in a market that covers multiple sectors the optimal design combines auctioned permits with output based allocations that are specific to each sector and increasing in its volatility when firms are better informed about the latter or must self select the regulator resort to some free i e lump sum allocations to sort firms out numerical exercises illustrate the policy relevance of our results the gains from considering output based allocations can be substantial

liquidity management of u s global banks internal capital markets in the great recession abstract the recent crisis highlighted the importance of globally active banks in linking markets one channel for this linkage is through how these banks manage liquidity across their entire banking organization we document that funds regularly flow between parent banks and their affiliates in diverse foreign markets we show that parent banks when hit by a funding shock reallocate liquidity in the organization according to a locational pecking order affiliate locations that are important for the parent bank revenue streams are relatively protected from liquidity reallocations in the organization while traditional funding locations are more extensively used to buffer shocks to the parent bank balance sheets

us climate policy a critical assessment of intensity standards intensity standards have gained substantial momentum as a regulatory instrument in us climate policy energy intensive and trade exposed industries are traditionally opposed to initiatives for domestic carbon pricing as they are particularly vulnerable to competitiveness losses and refer to counterproductive emission leakage in a unilateral climate policy context this has led to policy proposals where intensity standards on energy and carbon might at least in part substitute for explicit carbon pricing via taxes or emission allowances in this paper we study the economic efficiency properties of intensity standards as an instrument of unilateral climate policy we first develop a theoretical partial equilibrium framework and show that standards can have an ambiguous effect on carbon leakage we then use an applied computable general equilibrium model of the global economy to gain quantitative insights into the effects of intensity standards for the case of the us our numerical results show that intensity standards may rather increase than decrease carbon leakage moreover standards can lead to considerable welfare losses compared to uniform emission taxing the tradability of standards across industries is a mechanism that can reduce these negative effects

robust technology policy against emission leakage the case of upstream subsidies asymmetric regulation of a global pollutant between countries can alter the competitiveness of industries and lead to emissions leakage which hampers countries welfare in order to limit leakage governments consider supporting domestic trade exposed firms by subsidizing their investments in abatement technology the suppliers of such technologies tend to be less than perfectly competitive particularly when both emissions regulations and advanced technologies are new in this context of twin market failures we consider the relative effects and desirability of subsidies for abatement technology we find a more robust recommendation for upstream subsidies than for downstream subsidies downstream subsidies tend to increase global abatement technology prices reduce pollution abatement abroad and increase emission leakage on the contrary upstream subsidies reduce abatement technology prices and hence also emissions leakage

legal harmonization institutional quality and countries external positions a sectoral analysis abstract motivated by the action plan for a european capital markets union cmu this paper analyzes the potential for legal harmonization and convergence in institutional quality to affect capital market integration based on hand collected data on the implementation of eu directives our analysis yields three key insights first legal harmonization promotes portfolio equity holdings second discrepancies in institutional quality matter primarily for cross border debt positions third the relationship between external investments and harmonization varies significantly across sectors the non bank financial corporations which account for a large share of portfolio positions react more to institutional harmonization than do banks and the non financial private sector

financial development and economic growth abstract this paper examines the empirical relationship between long run growth and financial development proxied by the ratio between bank credit to the private sector and gdp we find that this proxy is positively correlated with growth in a large cross country sample but its impact changes across countries and is negative in a panel data for latin america we argue that the latter findings is the result of financial liberalization in a poor regulatory environment our findings also show that the main channel of transmission from financial development to growth is the efficiency rather than the volume of investment

embodied carbon tariffs in a world where the prospects of a global agreement to control greenhouse gas emissions are bleak the idea of using trade policy as an implicit regulation of foreign emission sources has gained many supporters in countries contemplating unilateral climate policies embodied carbon tariffs tax the direct and indirect carbon emissions embodied in imported goods the appeal seems obvious as oecd countries are on average large net importers of embodied emissions from non oecd countries carbon tariffs could substantially extend the reach of oecd climate policies we investigate this claim by simulating the effects of embodied carbon tariffs with a computable general equilibrium model of global trade and energy use we find that embodied carbon tariffs do effectively reduce carbon leakage however the scope for improvements in the global cost effectiveness of unilateral climate policy is limited the main welfare effect of the tariffs is to shift the burden of oecd climate policy to the developing world

alternative approaches for levelling carbon prices in a world with fragmented carbon markets abstract when carbon markets are fragmented and carbon prices vary across regions concerns arise that acting countries may encounter competitiveness and welfare losses and changes in production may lead to carbon leakage border carbon adjustments bcas have been proposed as a response measure to address these issues however more cooperative response policies such as linking carbon markets can also reduce the burden of emission reduction in acting countries and help level carbon prices this paper analyses the effects of bcas and both direct and indirect linking on welfare competitiveness and carbon leakage within a global recursive dynamic computable general equilibrium cge model results illustrate that an uneven carbon pricing can indeed lead to substantial competitiveness and welfare losses for acting countries as well as to carbon leakage of the instruments investigated in this paper bcas appear to be the best measure to preserve the competitiveness of acting countries as they shift part of the burden of emission reductions to non acting countries while bcas are effective for acting countries they cause severe welfare and competitiveness losses for non acting countries as a result bcas are less effective than linking in reducing global welfare losses as linking tends to be beneficial for both acting and non acting countries the advantages of bcas diminish as the carbon market is extended to more emission sources or to a wider international participation

the legal environment banks and long run economic growth this paper examines the relationship between the legal system and banlding development and traces this connection through to long run rates of per capita gdp growth capital stock growth and productivity growth the data indicate that countries where the legal system 1 emphasizes creditor rights and 2 rigorously enforces contracts have better developed banks than countries where laws do not give a high priority to creditors and where enforcement is lax furtherrnore the exogenous component of banking development the component defined by the legal environment is positively and robustly associated with per capita growth physical capital accumulation and productivity growth this paper addresses two questions first do crosscountry differences in the legal rights of creditors the efficiency of contract enforcement and the origin of the legal system explain cross country differences in the level of banking development second do better developed banks cause faster economic development that is is the component of banking development defined by the legal environment positively associated with long run rates of economic growth capital accumulation and productivity growth examining the relationship between the legal system and banking development is valuable irrespective of issues associated with long run growth first banks may influence the level of income per capita and the magnitude of cyclical fluctuations bernanke and gertler 1989 1990 second many economists stress that understanding the evolution of legal and financial systems is essential for understanding economic development north 1981 engerman and sokoloff 1996 consequently quantitative information on the relationship between the legal environment and banks will improve our understanding of business cycles and the process of economic development furthermore examining the causal links between banks and economic growth has both conceptual and policy implications on the conceptual front a long literature debates the importance of banks in economic development starting as early as bagehot 1873 economists have argued that better banks banks that are better at identifying creditworthy firms mobilizing savings pooling risks and facilitating transactions

carbon motivated border tax adjustments old wine in green bottles 1285 ben lockwood and john whalley we discuss emerging proposals for border tax adjustments btas to accompany commitments to reduce carbon emissions in the eu the us and other oecd economies the rationale offered for such border adjustment is that various entities such as the eu if making commitments to reduce emissions which go beyond those undertaken in other regions of the world impose added costs on domestic producers which create a competitive disadvantage for them some form of remedy is viewed as reasonable to maintain the competitiveness of domestic industries when responding to global environmental problems in this paper we argue that despite its current carbon manifestation the issue of border tax adjustments and both their rationale and their effects on trade are not new and despite the present debate which seems to overlook older literature have arisen before earlier debate on border tax adjustments occurred at the time of the adoption of the value added tax vat in the eu as a tax harmonisation target in the early 1960s but academic literature of the time showed that a change between origin and destination basis in the vat would be neutral and hence the use of a destination based tax in the eu to accompany the vat offered no trade advantage to europe here we argue that essentially the same arguments also apply for carbon motivated btas and in the current debate there seems to be a misconception between price level effects and relative price effects stemming from a bta which needs correcting we also argue that the impact of border tax adjustments should be viewed as independent of the motivation of the adjustments

a new database on the structure and development of the financial sector this article introduces a new database of indicators of financial structure and financial development across countries and over time the database is unique in that it combines a wide variety of indicators that measure the size activity and efficiency of financial intermediaries and markets it improves on previous efforts by presenting data on the public share of commercial banks introducing indicators of the size and activity of nonbank financial institutions and constructing measures of the size of bond and primary equity markets this article introduces a new database the first to provide comprehensive measures of the development structure and performance of the financial sector this database is the first to define and construct indicators of the size and activity of nonbank financial intermediaries such as insurance companies pension funds and non deposit money banks it is also the first to include indicators of the size of primary equity markets and primary and secondary bond markets in constructing the database authors carefully deflate measures and match stock and flow variables

the initial impact of eu ets verification events on stock prices this paper studies the impact of verified emissions publications in the european emissions trading scheme eu ets on the market value of participating companies using event study methodology on a unique sample of 368 listed companies we show that verified emissions only resulted in statistically significant market responses when the carbon price was high and allowance scarcity was anticipated the cross section analysis of abnormal returns surrounding the publication of verified emissions shows that share prices decrease when actual emissions relative to allocated emissions increase this negative relationship between allocation shortfalls and firm value is only significant for firms that are either carbon intensive compared to sector peers or are less likely to pass through carbon related costs in their product prices the results suggest that although the eu ets has been deemed unsuccessful so far due to over allocation and low carbon price shareholders initially perceived allowance holdings as value relevant our results highlight that a significant carbon market price and addressing pass through costing are essential for successful future reforms of the eu ets and other analogous carbon cap and trade systems implemented or planned worldwide

institutional quality and international trade institutions quality of contract enforcement property rights shareholder protection and the like have received a great deal of attention in recent years yet trade theory has not considered the implications of institutional differences beyond treating them simply as different technologies or taxes the purpose of this paper is twofold first we propose a simple model of international trade in which institutional differences are modeled within the framework of incomplete contracts we show that doing so reverses many of the conclusions obtained by equating institutions with productivity institutional differences as a source of comparative advantage imply among other things that the less developed country may not gain from trade and factor prices may actually diverge as a result of trade second we test empirically whether institutions act as a source of trade using data on us imports disaggregated by country and industry the empirical results provide evidence of institutional content of trade institutional differences are an important determinant of trade flows

investor protection and corporate governance recent research has documented large differences among countries in ownership concentration in publicly traded firms in the breadth and depth of capital markets in dividend policies and in the access of firms to external finance a common element to the explanations of these differences is how well investors both shareholders and creditors are protected by law from expropriation by the managers and controlling shareholders of firms we describe the differences in laws and the effectiveness of their enforcement across countries discuss the possible origins of these differences summarize their consequences and assess potential strategies of corporate governance reform we argue that the legal approach is a more fruitful way to understand corporate governance and its reform than the conventional distinction between bank centered and market centered financial systems

switching to carbon free production processes implications for carbon leakage and border carbon adjustment climate policy under partial global compliance raises concerns regarding carbon leakage while border carbon adjustment bca measures are a potential remedy they have also been criticised on various grounds this paper therefore investigates whether a policy fostering the switch to carbon free technologies can substitute for bcas a reason for the effectiveness of a targeted technology policy is that major leakage prone sectors such as iron and steel have two main sources of carbon emissions combustion of fossil fuels and industrial processes while combustion emissions can be reduced relatively easy by increasing energy efficiency reducing process emissions requires a switch to low carbon production processes e g in steel production by deploying electrolysis based on large scale solar electricity we show by means of a multi regional computable general equilibrium analysis that such a switch in steel production technology can eliminate a significant fraction of carbon leakage and also increase sectoral output and welfare since the necessary technologies are not available at large scale yet however are likely to be by 2020 a transitional bca scheme may be a crucial supportive instrument to foster such technology switches yet in the long run bca should be phased out to preserve the incentive for carbon free innovation

between a rock and a hard place a trade theory analysis of leakage under production and consumption based policies without a comprehensive global climate agreement carbon leakage remains a contentious issue consumption based pricing of emissions which could in practice be implemented with a full border tax adjustment bta has been forwarded as an option to increase the effectiveness of unilateral climate policy this paper questions the economic rationale behind this approach using a theoretical 2 times 2 trade model in which leakage occurs through terms of trade effects we show analytically first that consumption based pricing of emissions does not necessarily result in less leakage than production based policies second the sign of the optimal unilateral carbon tariff depends on the carbon intensity differential between the foreign country s exporting and non exporting sectors and not on the differential between home s and foreign s exporting sectors as implied by the full bta approach third based on empirical data for the year 2004 our model implies that full bta applied by the european union on e g imports from and exports to china would by shifting china s production from the export sector with a relatively low carbon intensity towards the more carbon intensive non export sector actually increase leakage

can an emission trading scheme promote the withdrawal of outdated capacity in energy intensive sectors a case study on china s iron and steel industry abstract outdated capacity and substantial potential for energy conservation are the two main features of energy intensive sectors in developing countries such countries also seek to implement market based options to further control domestic carbon emissions as well as to promote the withdrawal of outdated capacity and upgrade production level this paper presents a quantitative assessment of the emission trading scheme ets for china s iron and steel industry the diverse array of normal and outdated capacities was modeled in a two country three good partial equilibrium model simulation results show that the abatement potential can be underestimated if the energy saving effects that result from emission abatement are not considered in the scenario analysis we demonstrated that the free allocation of allowances can cause a competitiveness distortion among domestic normal and outdated capacities given the government s intention to promote outdated capacity withdrawal and production level upgrading an output based allocation approach is strongly suggested for china s iron and steel sector

climate change policy market structure and carbon leakage abstract the 1997 kyoto protocol on climate change obliges the industrialized countries to initiate the international effort of abating anthropogenic greenhouse gas ghg emissions if such an initiative is to be taken the associated competitive effects may lead to significant relocation of developed countries energy intensive production this paper examines this issue i adopt an oligopolistic structure combined with increasing returns to scale production technologies to represent the strategic interaction among the firms producing energy intensive products this representation is then embedded within a multi regional computable general equilibrium model which in turn is used for quantifying these relocational effects the results suggest that significant relocation of energy intensive industries away from the oecd may occur depending on the type of market structure with leakage rates as high as 130 in which case ghg control policies in the industrialized countries actually lead to higher global emissions

gravity in international finance abstract the past decade has witnessed an explosion of papers estimating gravity equations for cross border financial holdings without much of a theoretical foundation in this paper we develop a theory for bilateral asset holdings that takes a gravity form we discuss how to estimate international financial frictions and conduct comparative statics analysis within the context of the theory we also find though that reasonable extensions of the model no longer generate a gravity form while this does not significantly complicate estimation and comparative statics analysis it raises questions about the empirical validity of gravity specifications for cross border financial holdings that need to be addressed in future work

drivers of structural change in cross border banking since the global financial crisis abstract the paper analyzes the effects of changes to regulatory policy and to monetary policy on cross border bank lending since the global financial crisis cross border bank lending has decreased and the home bias in the credit portfolio of banks has risen sharply especially among banks in the euro area our results suggest that expansionary monetary policy in the source countries as measured by the change in reserves held at central banks has encouraged cross border lending both in euro area and non euro area countries regarding regulatory policy increases in financial supervisory power or independencve of the supervisory authorities have encouraged credit outflows from source countries the findings thus underline the importance of regulatory arbitrage as a driver of cross border bank flows since the global financial crisis however in the euro area arbitrage in capital stringency was linked to lower cross border lending since the crisis

border adjustment for european emissions trading competitiveness and carbon leakage unilateral or sub global policies to combat climate change are potentially sensitive to free riding and carbon leakage one way of dealing with carbon leakage and competitiveness is the imposition of border adjustment measures for competing imports for example in the form of the obligation to importers of goods to purchase and surrender emissions allowances to the authorities when importing in this paper we explore some implications of border adjustment measures in the eu ets for sectors that might be subject to carbon leakage we examine the implications of two variants of these measures on the competitiveness of these sectors and on the global environment with the help of a multi sector multi region computable general equilibrium cge model of the global economy our calculations suggest that border adjustment might reduce the sectoral rate of leakage of the iron and steel industry rather forcefully but that the reduction would be less for the mineral products sector including cement the reduction of the overall or macro rate of leakage would be modest so from an environmental point of view border tax adjustments would not be a very effective policy measure but might mainly be justified by considerations of sectoral competitiveness

targeted carbon tax reforms abstract in the presence of intersectoral linkages sector specific carbon tax changes can have complex general equilibrium effects in particular a carbon tax on the emissions of a sector can lead to an increase in aggregate emissions we analytically characterise how incremental taxes on the emissions of any set of sectors affect aggregate emissions we show that carbon tax reforms that target sectors based on their position in the production network can achieve a greater reduction in aggregate emissions than reforms that target sectors based on their direct emissions alone we illustrate the effects of carbon tax reforms by calibrating our intersectoral network model to the economies of two countries

comparing policies to combat emissions leakage border carbon adjustments versus rebates we explore conditions determining which anti leakage policies might be more effective complements to domestic greenhouse gas emissions regulation we consider four policies that could be combined with unilateral emissions pricing to counter effects on international competitiveness a border charge on imports a border rebate for exports full border adjustment and domestic output based rebating each option faces different potential legal hurdles in international trade law each also has different economic impacts while all can support competitiveness none is necessarily effective at reducing global emissions nor is it possible to rank order the options effectiveness depends on the relative emissions rates elasticities of substitution and consumption volumes we illustrate these results with simulations for the energy intensive sectors of three different economies the united states canada and europe although most controversial full border adjustment is usually most effective but output based rebating for key manufacturing sectors can achieve many of the gains

the great retrenchment international capital flows during the global financial crisis the current crisis saw an unprecedented collapse in international capital flows after years of rising financial globalization we identify the stylized facts and main drivers of this development the retrenchment in international capital flows is a highly heterogeneous phenomenon first across time being especially dramatic in the wake of the lehman brothers failure secondly across types of flows with banking flows being the hardest hit due to their sensitivity of risk perception and thirdly across regions with emerging economies experiencing a shorter lived retrenchment than developed economies our econometric analysis shows that the magnitude of the retrenchment in capital flows across countries is linked to the extent of international financial integration its specific nature with countries relying on bank flows being the hardest hit as well as domestic macroeconomic conditions and their connection to world trade flows gian maria milesi ferretti and cedric tille

financial system size in transition economies the effect of legal origin gorton and winton 1998 link the size of the banking system in transition economies to financial stability we provide empirical evidence consistent with their notion that the size of the financial system will be smaller in these countries this effect holds even after controlling for the effect of rule of law and or legal origin and other relevant variables transition economy status thus adds additional explanatory power to traditional law and finance explanations of financial development classification of transition economies by legal origin reveals that russian legal origin has a strong negative effect on financial development regression analysis shows claims on the private sector gross domestic product gdp to be 46 to 60 percentage points lower in the countries of the former soviet union and 23 to 39 percentage points lower in non soviet transition economies compared to countries of english legal origin there is a positive relation between claims on the private sector and the rule of law for a broad cross section of countries

assessment of environmental impacts embodied in u s china and u s india trade and related climate change policies we empirically investigate the ghg emissions embodied in the bilateral trade between the united states and china and the united states and india and their countryspecific and global environmental impacts in order to address the concerns of levelplaying field and carbon leakage associated with domestic carbon pricing scheme various border carbon adjustments have been proposed in recent u s climate change legislation employing gtap e model this study examines how and to what extent the proposed carbon tariffs and export subsidies potentially affect bilateral trade flow domestic production and the ghg emissions results indicate that carbon tariff effectively alleviates the impact of domestic carbon tax on vulnerable domestic industries and slightly raises their output and ghg emissions in addition it is also evident that a combined or full border adjustment policy has bigger impacts than an individual policy

european emissions trading and the international competitiveness of energy intensive industries a legal and political evaluation of possible supporting measures abstract the eu emissions trading directive is expected by european energy intensive industries to harm their competitiveness vis a vis non european competitors many additional measures have thus been proposed to level the playing field and to protect the competitiveness of european energy intensive industries within the larger effort of reducing europe s greenhouse gas emissions and of meeting its obligations under the 1997 kyoto protocol this article evaluates a range of proposed measures based on a set of political and legal criteria including environmental effectiveness the need to consider differentiated commitments responsibilities and capabilities conformity with world trade law and european union law and europe s overall political interests we discuss measures that could be adopted by the european union and its member states such as direct support for energy intensive industries restrictions of energy intensive imports into the european union through border cost adjustments quotas or technical regulations and cost reimbursement for affected developing countries we also analyse measures available to multilateral institutions such as the united nations framework convention on climate change and its kyoto protocol and the world trade organisation we conclude with a classification of the discussed measures with red unfeasible yellow potentially feasible or green feasible labels

growth in transition what we know what we don t and what we should abstract this essay surveys macroeconomic issues that marked the transition from planned to market economy in central and eastern european and former soviet union countries we first establish stylized facts of the transition so far we then critically survey the theoretical literature on transition discussing explanations for the initial output fall and mediumterm issues such as optimal speed of transition disorganization institutions and sectoral reallocation as source of output dynamics we review the empirical literature to assess how well it translates the theoretical models and explains the stylized facts we conclude with suggestions for future research

leakage in regional environmental policy the case of the regional greenhouse gas initiative abstract subglobal and subnational greenhouse gas policies are often thought to be less effective than comprehensive policies as production and emissions of trade exposed industries may move from the regulated to the unregulated regions a process referred to as leakage leakage negates some emission reductions from the regulated regions we use detailed electricity generation and transmission data to show that this is the case for the regional greenhouse gas initiative rggi a co2 cap and trade program for the electricity sector in select northeastern u s states more specifically our results indicate that rggi induced a reduction in coal fired generation in rggi states and an increase in ngcc generation in rggi surrounding regions this finding suggests that the pollution haven hypothesis holds for state level variation in environmental policy even when compliance costs are low

green technology transfers and border tax adjustments we develop a two country general equilibrium model of foreign technology transfers tied to environmental clean up and border tax adjustments in the presence of transboundary pollution pollution is generated in the aid recipient as a by product in the production of a dirty good which it consumes as well as exports to the donor country in contrast to the literature which typically treats aid as a monetary transfer we assume that foreign aid consists of a transfer of environmental technology that lowers the cost of public clean up we also consider a border tax adjustment bta as a secondary policy instrument used in order to internalize the residual transboundary externality we study the environmental and welfare outcomes of the technology transfer and the bta as well as the interaction between the two policy instruments we derive conditions under which the additional presence of a bta may lead to a lower transfer and less public pollution abatement in the recipient with counter productive consequences for both the environment and welfare contrary to intuition we find that the green technology transfer and the border tax adjustment are not always complements

impacts of climate policy on the competitiveness of canadian industry how big and how to mitigate competitiveness concerns have been at the forefront of climate policy debates in canada particularly as a result of its high energy intensity and significant exposure to international markets this paper uses a dynamic computable general equilibrium model to assess the likely impacts on sectoral competitiveness that would accompany efforts to meet greenhouse gas mitigation targets that have been set by the canadian government additionally it evaluates several design mechanisms that could be used to reduce the negative competiveness impacts associated with adoption of domestic climate policies the analysis suggests that several sectors would likely face significant competiveness challenges under a reference scenario in which permits are given to emitters in lump sum however it finds that competiveness impacts can be minimized by using output based recycling of permits or by using border tax adjustments

output based rebating of carbon taxes in a neighbour s backyard competitiveness leakage and welfare we investigate how in an open economy carbon taxes combined with output based rebating obr perform in interaction with the carbon policies of a large neighbouring trading partner analytical results suggest that whether the purpose of the obr policy is to compensate firms for carbon tax burdens or to maximize welfare accounting for global emission reductions the obr rate should be positive in policy relevant cases numerical simulations for canada with the us as the neighbouring trading partner indicate that the impact of us policies on the obr rate will depend crucially on the purpose of the canadian obr policies if for a given us carbon policy canada s aim is to restore the competitiveness of domestic emission intensive and trade exposed eite firms to the same level as before the introduction of its own carbon taxation we find that the necessary domestic obr rates will be insensitive to the foreign carbon policies however if not only the canadian carbon tax but also an equally high us tax is introduced compensatory canadian obr rates will be up to 50 lower depending on the sector and on us obr policy if the policy objective is to increase economy wide allocative efficiency welfare of canadian policies by accounting for carbon leakage the us policies will have only a minor downward pressure on desirable obr rates in canada practical choices of obr rates hardly affect overall domestic economic performance thus output based rebating qualifies as an instrument for compensating eite industries without a large sacrifice in terms of economy wide allocative efficiency

using output based allocations to manage volatility and leakage in pollution markets abstract output based allocations obas are typically used in emission trading systems ets with a fixed cap to mitigate leakage in sectors at risk recent work has shown they may also be welfare enhancing in markets subject to supply and demand shocks by introducing some flexibility in the total cap resulting in a carbon price closer to marginal damage we extend previous work to simultaneously include both leakage and volatility we study how oba permits can be implemented under an overall cap that may change with the level of production in contrast with a design that deducts oba permits from the overall permit allocation as is the current practice in the eu ets and california we show that introducing oba permits while keeping the overall cap fixed would only increase price fluctuations and induce severe welfare losses to non oba sectors

carbon tax emission standards and carbon leak under price competition we consider a two country model of price competition with one polluting firm in each country and differentiated products assuming away to simplify abatement efforts and input substitution we compare the impact on output leakages and trade volumes of a carbon tax versus an emission standard policy unilaterally enacted by the home country under the tax the two firms set their prices simultaneously in a bertrand game under the standard the home firm s price is conditioned on the price of the foreign firm so as to abide the emission constraint as a result the tax leads to higher leakages and global emissions than the standard the standard also implies a better trade balance for the home country than the tax

building climate coalitions on preferential free trade agreements in this paper we discuss the endogenous formation of climate coalitions in an issue linkage regime in particular we propose a preferential free trade agreement on which a climate coalition should be built the basic idea is that the gains of free trade can provide strong incentives for countries to join the coalition as a framework a multi stage strategic trade model is employed in which each country may set an emission cap being effective on a permit market in addition a discriminatory import tariff may be imposed on dirty goods however at the heart of our approach is a preferential free trade arrangement among the members of a climate coalition leading to a favourable shift in the terms of trade as a main result trade liberalisation is found as an institution highly effective in building climate coalitions in particular the parametrical simulation of the model shows that participation in joint emission reduction is higher consumption patterns are more environmentally friendly and coalitional welfare is much more improved than in case of a single issue environmental agreement

carbon control policies competitiveness and border tax adjustments abstract several propositions have recently been made to use border tax adjustments btas to address the loss of competitiveness induced by unilateral stringent domestic pollution control policies this paper explores in a general equilibrium framework the sectoral and welfare implications of a unilateral domestic ghg control policy combined with a bta scheme using the canadian economy as an illustration we assess the extent to which btas achieve their objectives and analyze the impacts of different methods of recycling the bta proceeds to support domestic industries our simulation results suggest that imposing btas on the imports of non fossil and energy intensive products reduces or removes completely the negative competitiveness impacts that domestic industries suffer from the use of the proceeds of the btas to support domestic energy intensive industries improves their competitiveness and more importantly in some cases overprotects them as it allows them to even increase their output in comparison to the benchmark without emissions control our results also shed light on the existence of heterogeneity in the composition of energy intensive industries as far as the recycling method of the bta proceeds is concerned energy intensive industries that are more oriented toward the domestic market are better off with the recycling of the bta proceeds towards gross output than towards exports alone finally abstracting from the environmental benefits of reduced emissions we find that a bta entails a higher welfare cost to households

temporal spillovers in land conservation abstract temporal spillovers occur when a conservation program changes what happens to land outside the temporal window of the conservation contract this may happen when conservation improves land so that returns to non conservation uses are increased or when landowners preferences become more pro conservation as they see land flourish under conservation for example these post contract changes may occur on the extensive margin acres of land conserved or intensive margin intensity of land in a given use if temporal spillovers exist benefits from conservation programs estimated by focusing solely on the effects that occur during the conservation contract will overstate or understate the true benefits of the program i lay out a simple model of temporal spillovers i test this model in the context of the united states conservation reserve program crp i use a pre analysis sample specification step to choose counterfactual land most like the crp land on the extensive margin i find that crp causes some land to be 20 25 more likely to be farmed potentially offsetting some environmental benefits however farmed ex crp land is slightly more likely to use a conservation practice this is a mitigating factor on the intensive margin

robust policies to mitigate carbon leakage abstract unilateral climate policy induces carbon leakage through the relocation of emission intensive and trade exposed industries to regions without emission regulation previous studies suggest that emission pricing combined with border carbon adjustment is a second best instrument and more cost effective than output based rebating we show that the combination of output based rebating and a consumption tax for emission intensive and trade exposed goods can be equivalent with border carbon adjustment moreover it is welfare improving for a region that implements emission pricing along with output based rebating to introduce such a consumption tax the welfare gain is particularly large if output based rebating is already implemented for a sector that is not much exposed to leakage e g due to uncertainty about exposure or due to lobbying activities thus supplementing output based rebating with a consumption tax constitutes robust policies to mitigate carbon leakage

output based allocation of emissions permits for mitigating tax and trade interactions the allocation of tradable emissions permits has important efficiency as well as distributional effects when tax and trade distortions are taken into account we compare different rules for allocating carbon allowances within sectors lumpsum grandfathering output based allocation oba auctioning and among sectors historical emissions or value added shares the output subsidies implicit in oba mitigate tax interactions unlike grand fathering oba with sectoral distributions based on value added is similar to revenue recycling with auctioning oba based on historical emissions supports heavier polluters more effectively counter acting carbon leakage but at higher welfare costs less energy intensive sectors are also sensitive to allocation rules

to b ta or not to b ta on the legality and desirability of border tax adjustments from a trade perspective this paper asks two questions concerning border tax adjustments for climate purposes when viewed from a trade perspective first under what conditions are btas possible in the wto world to address this issue the paper provides a detailed discussion of the relevant law and case law we also apply our main conclusions to what we consider to be paradigmatic cases of measures to address climate change where trade concerns are raised we conclude that the wto regime is no major obstacle to those aspiring to use btas although the allocation of the burden of proof could be a concern the second issue addressed is whether the economic literature on the desirability of btas adequately reflects concerns that have been raised in the trade policy community here we conclude that it has hardly addressed these concerns at all we also point to some aspects of btas that would need to be taken into account in a more complete analysis

financial development and economic growth views and agenda this critique argues that the preponderance of theoretical reasoning and empirical evidence suggests a positive first order relationship between financial development and economic growth the body of work would push even most skeptics toward the belief that the development of financial markets and institutions is a critical and inextricable part of the growth process and away from the view that the financial system is an inconsequential sideshow responding passively to economic growth many gaps remain however and the paper highlights areas in acute need of additional research

reduced cross border lending and financing costs of smes abstract this paper investigates how the withdrawal of banks from their cross border business impacted the borrowing costs of european firms since the crisis we combine aggregate information on total and cross border credit with firm level survey data for the period 2010 2014 we find that the decline in cross border lending led to a deterioration in the borrowing conditions of small firms in countries with more pronounced reductions in cross border credit inflows the likelihood of a rise in firms external financing costs increased this result is mainly driven by the interbank channel which plays a crucial role in transmitting shocks to the real sector across borders
