conditional eurobonds and the eurozone sovereign debt crisis this paper proposes that all new euro area sovereign borrowing be in the form of jointly guaranteed eurobonds to avoid classic moral hazard problems and to insure the guarantors against default each country would pay a risk premium conditional on economic fundamentals to a joint debt management agency this suggests that these bonds be called euro insurance bonds while the sovereign debt markets have taken increasing account of the economic fundamentals the signal to noise ratio has been weakened by huge market volatility so undercutting incentives for appropriate reforms and obscuring economic realities for voters this paper uses an econometric model to show that competitiveness public and private debt to gdp and the fall out from housing market crises are the most relevant economic fundamentals formula based risk spreads based on these fundamentals would provide clear incentives for governments to be more oriented towards economic reforms to promote long run growth than mere fiscal contraction putting more weight on incentives that come from risk spreads than on fiscal centralization and the associated heavy bureaucratic procedures would promote the principle of subsidiarity to which member states subscribe the paper compares euro insurance bonds incorporating these risk spreads with other policy proposals copyright 2013 oxford university press

international evidence on fiscal solvency is fiscal policy responsible abstract we conduct a cross country empirical analysis of fiscal solvency based on dynamic stochastic general equilibrium conditions the results show evidence of fiscal solvency in the form of a robust positive conditional response of the primary balance to changes in public debt in panels for emerging and industrial economies and in a combined panel emerging economies show a stronger response and hence converge to lower mean debt output ratios as observed in the data the results are weaker for countries with debt ratios exceeding panel means and medians hence we can separate countries where fiscal solvency holds from those where it remains in doubt

eurozone sovereign debt restructuring keeping the vultures at bay the eurozone debt crisis has stimulated lively debate on mechanisms for sovereign debt restructuring the immediate threat of exit and the breakup of the currency union may have abated but the problem of dealing with significant debt overhang remains after considering two broad approaches institutional versus contractual we look at a hybrid solution that combines the best of both in addition to debt contracts with collective action clauses this includes a key amendment to the treaty establishing the european stability mechanism together with innovative state contingent contracts and a special purpose vehicle to market them

political economy of public policies insights from distortions to agricultural and food markets the agricultural and food sector is an ideal case for investigating the political economy of public policies many of the policy developments in this sector since the 1950s have been sudden and transformational while others have been gradual but persistent this paper reviews and synthesizes the literature on trends and fluctuations in market distortions and the political economy explanations that have been advanced based on a rich global data set covering a half century of evidence on commodities countries and policy instruments the paper identifies hypotheses that have been explored in the literature on the extent of market distortions and the conditions under which reform may be feasible

sovereign debt and its restructuring framework in the eurozone debt is a particularly serious macroeconomic problem in the eurozone public debt ratios are high by international historical standards with no immediate prospect of a significant reduction private corporate and household debt ratios are either flat or rising banks remain fragile and impose a contingent liability on the public purse the most stressed economies have not had the option of renewing economic growth through exchange rate depreciation and a boost to exports thus fiscal austerity has been their principal instrument to achieve debt reduction but since austerity also hurts growth the debt to gdp ratios have barely budged persistent low growth has also created deflationary tendencies which further raise the challenge of debt reduction

financial crises and the multilateral response what the historical record shows abstract we provide a synoptic description of financial crises and the multilateral response over the course of the last four decades we present both indicators of economic performance around crisis dates and a comprehensive description of multilateral rescue efforts while emergency lending has grown reliance on debt restructuring broadly speaking has declined this leads us to ask what can be done to rebalance the management of debt problems toward a better mix of emergency lending and private sector burden sharing in particular we explore the idea of sovereign cocos contingent debt securities that automatically reduce payment obligations in the event of debt sustainability problems

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

fiscal consequences for mexico of adopting the dollar dollarization implies a reduction in the menu of assets available to the government and to the private sector in managing risk whatever the gains from dollarization the costs of reducing the asset menu need to be weighed against them this paper presents models one a simple generalization of a well known model of tax smoothing by ba1ao in which these costs are explicit along the way it suggests that there is likely to be no reduction in interest costs to the government from dollarization recently economists have been paying increasing attention to a dynamic general equilibrium approach to the theory of the price level that is often called the fiscal theory of the price level or ftpl this way of thinking emphasizes the role of fiscal and monetary policy in determining the risk and return properties of government liabilities it is particularly useful in analyzing proposals for large scale institutional changes that imply shifts in monetary and fiscal policies when dollarization is considered from this perspective some disadvantages are brought to light that may not be so apparent from other points of view section 1 below lays out the main ideas of ftpl section 2 displays a model that extends an earlier one of barro s to argue that optimal fiscal policy will use surprise inflation to achieve lower deadweight tax loss than would otherwise be possible section 3 considers the composition of government liabilities along the lines of the theory of corporate finance asking if dollarization will reduce the cost of funds section 4 presents annual estimates of the unanticipated returns to holders of u s government debt to show that these are substantial and are to some extent timed to match legitimate periods of fiscal stress as the optimality theory of section 2 would suggest section s discusses the lendel of last resort function and its connection to these fiscal issues section 6 briefly discusses some alternatives to pure dollarization in our concluding section 7 we sum up finding much to worry about in the prospect of dollarization

the political economy of u s wheat legislation bruce a babcock colin a carter and andrew schmitz both taxpayer subsidies to u s wheat producers and domestic deadweight losses increased as a result of the u s wheat program adopted in 1985 a calculation of the costs and benefits of alternative wheat policies shows that mandatory production controls with no taxpayer expense could have made wheat producers as well off as the adopted policy becker s theory of competition among interest groups and peltzman s theory of the equilibrium amount of regulation are shown to be consistent with the observed policy choice if the list of affected interest groups includes agricultural input suppliers and grain marketing firms i introduction every five years congress drafts new farm legislation dictating the provisions of commodity programs for cotton and the major food and feed grains for the subsequent five years from 1973 through 1985 the primary features of the commodity programs were guaranteed farm prices and government stockholding activities deadweight losses from the programs during this time were minimal market prices were generally higher than the government defended price floors because of a booming export market legislated increases in commodity support prices combined with a severe drop off in the demand for agricultural exports beginning in 1982 increased the economic costs of the commodity programs the u s price floor became the world price for wheat cotton and corn grain stocks accumulated while government payments to u s farmers grew to unprecedented levels most agricultural interest groups in 1984 agreed that an overhaul of agricultural policy was necessary supporters of large levels of production and exports wanted to stimulate the demand for exports by eliminating price floors others felt that the united states should reduce budgetary costs by using direct supply controls to raise farm prices the clear winners in the new 1985 farm bill were the proponents of maintained production levels and expanded exports the new policy froze the relatively high supply prices received by farmers while simultaneously lowering price floors becker 1983 argues that two forces mainly determine the outcome of policy debates the first following stigler 1971 and peltzman 1976 is the relative efficiency with which interest groups exert political pressure interest groups that are efficient in exerting political pressure can increase the subsidization or decrease the tax burden of their constituents the second force is the extent of deadweight losses associated with proposed policies those policies with lower deadweight losses are ceteris paribus more likely to be adopted for the simple reason that less tax needs to be collected from losing interest groups for given transfers to winning groups gardner 1987 finds empirical evidence that both the ability to redistribute efficiently and the effectiveness of political organizations help explain which farm commodities have received the most government support since 1930 his study provides little insight however into which force is more important in determining the type of redistribution policies that are ultimately adopted for a given commodity an examination of the wheat program adopted in the 1985 farm bill and alternative policies that were rejected provides an opportunity to determine whether the efficiency of programs or the political prowess of interest groups is more important in determining policy outcomes this task requires a calculation of the magnitudes and the distribution of costs and benefits of the chosen policy and alternative policies costs and benefits are calculated for 1 a continuation of the 1981 farm bill policies through 1986 1990 2 the adopted 1985 farm bill policies and 3 mandatory production controls all three alternatives are examined relative to a laissez faire policy whereby the u s government has no direct involvement in agriculture

neglected risks financial innovation and financial fragility abstract we present a standard model of financial innovation in which intermediaries engineer securities with cash flows that investors seek but modify two assumptions first investors and possibly intermediaries neglect certain unlikely risks second investors demand securities with safe cash flows financial intermediaries cater to these preferences and beliefs by engineering securities perceived to be safe but exposed to neglected risks because the risks are neglected security issuance is excessive as investors eventually recognize these risks they fly back to the safety of traditional securities and markets become fragile even without leverage precisely because the volume of new claims is excessive

co ordination failure moral hazard and sovereign bankruptcy procedures we study a model of sovereign debt crisis that combines problems of creditor co ordination and debtor moral hazard solving the sovereign debtor s incentives leads to excessive rollover failure by creditors when sovereign default occurs we discuss how the incidence of crises might be reduced by international sovereign bankruptcy procedures involving contractibility of sovereign debtor s payoffs suspension of convertibility in a discovery phase and penalties in case of malfeasance in relation to the current debate this is more akin to the imf s sovereign debt restructuring mechanism than the collective action clauses promoted by others

foreign debt versus domestic debt in the euro area the aftermath of the 2008 financial crisis has led to a sharp rise in public debt throughout the developed world the problem is particularly acute within the euro area where several governments needed financial assistance from the international monetary fund and the european stability mechanism this paper argues that public debt poses much greater problems when it is owed to foreigners i e when it constitutes foreign debt this view implies that the key to overcoming the euro crisis is in the external adjustment not the fiscal adjustment another implication is that in a crisis a strong fiscal adjustment is desirable not because it can immediately reduce the public debt gdp ratio but because it reduces domestic absorption and thus reinforces the external adjustment copyright 2013 oxford university press

consequences of discretion in the formation of commodities policy abstract in a simple model of endogenous primary commodity price support policy i policy is affected by private inventories and ii private inventories are affected by speculative attempts to forecast policy the interaction between these two forces is rich yielding bubbles and extrinsic volatility thus helping to explain some odd episodes observed in commodity markets in addition under some conditions a government that wishes to support the price but is unable to commit to future action may be impotent and a government that does not want to support the price may be trapped into doing so by speculative activity

the effects of commodity price stabilization programs in this paper the authors analyze the effects of commodity programs in which the government attempts to support and stabilize price through open market purchases and sales specifically they as sess the effects of such programs on the u s soybean market using a rational expectations model that allows for private storage expected price responsive production and arbitrary support and release price s a salient feature of the model is that private storage and product ion behavior adjusts to changes in government policy stochastic simu lations of the market model demonstrate that price stabilization prog rams can reduce long run market price and destabilize producer revenu e copyright 1988 by american economic association

on the contribution of game theory to the study of sovereign debt and default this paper reviews the lessons learned from the application of the tools of game theory to the theoretical study of sovereign debt and default we focus on two main questions first we review answers to the most fundamental question in the theory of sovereign debt given that there is no supranational institution for enforcing the repayment of debts why do countries ever repay their debts second we review theories of the process by which sovereign debts are restructured with a view to answering the following question why does the process of sovereign debt restructuring appear so inefficient the first question raises issues in the design of self enforcing contracts and on the credibility of threats to punish a country in default the second question involves applications of the theory of bargaining in environments where the parties to a bargain cannot commit to honour the terms of the bargain or even commit to enter into negotiations in the first place copyright 2013 oxford university press

sovereign debt restructuring the judge the vultures and creditor rights what role did the us courts play in the argentine debt swap of 2005 what implications does this have for the future of creditor rights in sovereign bond markets the judge in the argentine case has it appears deftly exploited creditor heterogeneity between holdouts seeking capital gains and institutional investors wanting a settlement to promote a swap with a supermajority of creditors our analysis of argentine debt litigation reveals a judge mediated sovereign debt restructuring which resolves key issues of transition and aggregation two of the tasks envisaged for the imf s stillborn sovereign debt restructuring mechanism for the future we discuss how judge mediated sovereign debt restructuring together with creditor committees could complement collective action clauses in sovereign bond contracts

sovereign debt defaults insights from history history provides many insights to address the issue of sovereign debt defaults this article first presents a detailed account of defaults in historical perspective it then discusses the solutions devised in the past to address sovereign debt crises and puts these into perspective with today s answers when crises occur finally the paper stresses the role of history when the events studied do not occur frequently and when archival data may shed new light on the process of the resolution of crises the impact of odious debts declarations of state succession and of international relations on sovereign defaults and on their settlement is thus also addressed copyright 2013 oxford university press

delaying the inevitable interest rate defense and balance of payments crises the classical model of balance of payments crises implicitly assumes that the central bank sits passively as international reserves dwindle in practice however central banks typically defend pegs aggressively by raising short term interest rates this paper analyzes the feasibility and optimality of raising interest rates to delay a potential bop crisis interest rate policy works through two distinct channels by raising demand for domestic interest bearing liquid assets higher interest rates tend to delay the crisis higher interest rates however increase public debt service and imply higher future inflation which tends to bring forward the crisis we show that under certain conditions it is feasible to delay the crisis but raising interest rates beyond a certain point may actually hasten the crisis a similar nonmonotonic relationship emerges between welfare and the increase in interest rates it is thus optimal to engage in some active interest rate defense but only up to a certain point i

qe a successful start may be running into diminishing returns existing studies may have underestimated the impact of qe1 on uk gdp because they did not take full account of the beneficial effect on credit risk spreads and on the exchange rate however all such effects were also influenced by the roughly simultaneous introduction of similar easing in the usa which complicates the analysis another area where qe has been positive is in reducing public sector borrowing costs where qe1 and subsequent rounds have disappointed is in their inability to stimulate a recovery in credit and monetary growth amid an increased desire among banks to hold far more of their reserves at the central bank moreover there is growing evidence of significant diminishing returns in qe2 as gilt rates have already fallen to historically low levels and the risk is that if policy makers fail to resuscitate the bank lending channel further rounds of qe could potentially have negative returns

sovereign default and the euro the introduction of the euro meant that countries with sovereign debt problems could not use monetization and devaluation as a way to prevent default the institutional structures of the euro were also widely thought to prevent a country in difficulties being bailed out by other euro members or having its sovereign debt purchased by the european central bank ecb despite these restrictions there was relatively little discussion about sovereign default in pre economic and monetary union debates among economists and financial markets priced in almost no default risk in the pre crisis years the crisis has seen bailouts and bond purchases by the ecb but there has also been a sovereign default inside the euro and further defaults seem likely the introduction of the euro was intended to bring greater stability by ending devaluations triggered by self fulfilling runs on a currency while this particular scenario can no longer happen this paper discusses mechanisms whereby expectations that a country may leave the euro can lead to this outcome occurring copyright 2013 oxford university press

causes of u s farm commodity programs this paper i s an attempt to explain variations by commodity in producer protection afforded by farm price support programs since the1930s particularly emphasized are theideas that these programs are essentially income redistributional measures and that given political forces the programs are attempts to redistribute efficiently variables associated with the cost to producers of generating political pressure and the social cost deadweight losses of redistribution are both found to be empirically important copyright 1987 by university of chicago press

money as stock abstract the fiscal theory determines the price level from the value of nominal government debt as a claim to government primary surpluses just as private stock is valued as a claim to corporate profits valuation equations are not constraints so this theory does not mistreat the government s intertemporal budget constraint i anchor the analysis in a simple cash in advance model when money demand falls to zero i show that the price level can still be determined by the government debt valuation equation

radio s impact on public spending if informed voters receive favorable policies then the invention of a new mass medium may affect government policies since it affects who is informed and who is not these ideas are developed in a voting model the model forms the basis for an empirical investigation of a major new deal relief program implemented in the middle of the expansion period of radio the main empirical finding is that u s counties with many radio listeners received more relief funds more funds were allocated to poor counties with high unemployment but controlling for these and other variables the effects of radio are large and highly significant

the perverse impact of calling for energy conservation abstract in periods of high energy demand utilities frequently issue emergency appeals for conservation over peak hours to reduce brownout risk we estimate the impact of such appeals using high frequency data on actual and forecasted electricity generation pollutant emission measures and real time prices our results suggest a perverse impact while there is no significant reduction in grid stress over superpeak hours such calls lead to increased off peak generation co 2 emissions and price volatility we postulate that consumer attempts at load shifting lead to this result

a strategy for efficient debt reduction f or the past seven years the u s government has managed the debt crisis with the preeminent goal of sustaining the flow of debt servicing payments from the debtor countries to the commercial banks the focus on the banks especially in the first years of the crisis 1982 85 is easily explained several money center banks had exposure of nearly 200 percent of bank capital in latin america alone upon the outbreak of the crisis in 1982 a widespread suspension of debt service payments could well have sunk several major banks i have discussed the u s government s policy focus on the debt servicing to the commercial banks in sachs 1986b 1989c and sachs and huizinga 1987 but today those policies are being revised after years of steady decline in the exposure ratios of the most heavily exposed banks the risk of a u s banking crash as the result of the debt crisis is now virtually nonexistent in addition the burden of debt payments is contributing to profound economic crises and growing political instability in almost all of the democracies in latin america a wide range of analysts now concurs that the debt burden should be reduced not only for the sake of the debtors but also for the sake of the creditors who have an important long run stake in allowing the developing countries to surmount the current acute crisis the brady plan unveiled by secretary of treasury nicholas brady in march 1989 is based on the need for a reduction of the debt burden

the political economy of government responsiveness theory and evidence from india the determinants of government responsiveness to its citizens is a key issue in political economy here we develop a model based on the solution of political agency problems having a more informed an politically active electorate strengthens incentives for governments to be responsive this suggests that there is a role both for democratic institutions and the mass media in ensuring that the preferences of citizens are reflected in policy the ideas behind the model are tested on panel data from india we show that public food distribution and calamity relief expenditure are greater controlling for shocks where governments face greater electoral accountability and where newspaper circulation is highest

fixed exchange rates as a means to price stability what have we learned abstract the paper discusses what we have learned from last year s currency crises in erm and the nordic countries about fixed exchange rates as a means to achieve price stability after discussing the explanations for the crises the paper concludes that fixed exchange rates are not a shortcut to price stability monetary stability and credibility have to be built at home and cannot easily be imported from abroad fixed exchange rates are more fragile and difficult to maintain than previously thought they may even be in conflict with price stability by inducing a procyclical destabilizing monetary policy and by inducing an inflation bias building monetary credibility is even more important with flexible exchange rates

crisis costs and debtor discipline the efficacy of public policy in sovereign debt crises abstract recent debate on the reform of the international financial architecture has highlighted the potentially important role of the official sector in crisis management we examine how such public intervention in sovereign debt crises affects efficiency ex ante and ex post our results shed light on the scale of capital inflows and the implications for debtor country output of such a regime the efficacy of measures such as officially sanctioned stays on creditor litigation depend critically on the quality of public sector surveillance and the size of the costs of sovereign debt crises

historical research on international lending and debt the parallels between debt crises past and present have attracted a large number of social scientists to the history of foreign lending and default in this article i describe the findings of the recent literature on the subject the questions posed have obvious relevance to the current policy debate over the debt of less developed countries what features of international capital markets have long rendered them vulnerable to generalized crisis what events tend to spawn debt servicing difficulties and to provoke default what have been the consequences of default for lenders and borrowers what approaches historically have proven most effective at clearing away the residue of debt crises i concentrate on 20th century experience on the lending of the 1920s on the debt crisis of the 1930s and on the recovery of capital markets after world war ii

under what circumstances past and present have international rescues of countries in financial distress been successful recent events in asia and other parts of the globe have prompted calls from many quarters for international rescue of the monetary or fiscal authorities in distressed countries we contrast the experience of rescues of monetary authorities before 1973 of advanced countries temporarily short of liquidity with recent experience of bailouts international rescues in the past have involved relatively small amounts of money sufficient to stave off devaluation or abandonment of a fixed exchange rate while remedial policies were put in place recent bailouts have involved handing over relatively large amounts to both foreign lenders and domestic investors after devaluation of a pegged exchange rate to avoid their incurring wealth losses we document past rescues whether successful or unsuccessful by monetary regimes and show what is different today from past experience

collective action clauses in international sovereign bond contracts whence the opposition in the debate on strengthening the international financial architecture which peaked in 2002 after a series of emerging market sovereign debt crises the universal adoption of collective action clauses cacs was the most promising reform proposal academics and the official sector had been promoting cacs at least since 1995 yet market practice did not begin to change until 2003 this delay is often attributed to the opposition of investors and sovereign borrower to cacs this paper evaluates the publicly stated as well as the suspected private motives of the two sides to block the spread of cacs it draws on a wide range of existing evidence and adds some new theoretical considerations to show that there is no reason to be sceptical of cacs unless bailouts exist as an alternative crisis resolution mechanism this conclusion may be of interest purely for the sake of historical accuracy but more importantly it may help to better understand any potential future resistance by market participants e g in the process of introducing cacs in bonds governed by german law

television and voter turnout i use variation across markets in the timing of television s introduction to identify its impact on voter turnout the estimated effect is significantly negative accounting for between a quarter and a half of the total decline in turnout since the 1950s i argue that substitution away from other media with more political coverage provides a plausible mechanism linking television to voting as evidence for this i show that the entry of television in a market coincided with sharp drops in consumption of newspapers and radio and in political knowledge as measured by election surveys i also show that both the information and turnout effects were largest in off year congressional elections which receive extensive coverage in newspapers but little or no coverage on television

macroeconomic policy in light of the credit crunch the return of counter cyclical fiscal policy this paper begins by arguing that the 2007 8 credit crunch does not require a fundamental reevaluation of monetary policy the crunch occurred because regulation was too lax and we need to develop new and more effective tools of regulatory control to focus on current account imbalances or mistakes in setting interest rates as a prime cause of the credit crunch is unconvincing and has the danger of diverting attention away from the need to increase financial regulation the current recession does require a re evaluation of the role fiscal policy can play when interest rates hit a zero bound an expansionary fiscal policy is required because monetary policy makers are reluctant to promise higher future inflation and the impact of quantitative easing is likely to be small although rising debt may place a limit on how much conventional fiscal policy can do not all expansionary fiscal measures require additional borrowing there are two important lessons for the future first although monetary policy should remain the primary tool to stabilize the business cycle the combination of fiscal implementation lags and uncertainty means that some precautionary fiscal action may be appropriate during the early phase of some economic downturns second to play this backstop stabilization role effectively a policy that results in the government debt to gdp ratio declining albeit gradually and erratically in normal times seems appropriate

the theory of rational bubbles in stock prices free disposal of equity which directly rules out the existence of negative rational bubbles in stock pric es also imposes theoretical restrictions on the possible existence o f positive rational bubbles the analysis in this paper shows that a positive rational bubble can start only on the first date of trading of a stock thus the existence of a rational bubble at any date woul d imply that the stock has been overvalued relative to market fundame ntals since the first date of trading and that prior to the first da te of trading the issuer of the stock and potential stockholders who anticipated the initial pricing of the stock expected that the stock would be overvalued copyright 1988 by royal economic society

efficient redistribution through commodity markets efficiency in redistribution is measured in terms of deadweight loss generated per dollar of economic surplus transferred between consumers and producers of a commodity by means of market intervention the implications of supply and demand elasticities for efficiency in redistribution are examined with special attention to the comparison of production control and deficiency payment programs the results may be used to aid in the evaluation of commodity programs and as a basis for consideration of the hypothesis that observed policies are efficient given the political power of interest groups

rules and discretion in trade policy abstract we argue that the second best nature of trade policy suggests that the issue of time consistency will be an important consideration in determining the extent and efficacy of such intervention if production decisions are made prior to consumption decisions governments with sufficient policy discretion will be tempted to surprise producers with policies other than those announced in an effort to separate the consumption tax aspect from the production subsidy dimension of a tariff this leads optimal trade policy to be time inconsistent in a wide range of environments we explore this idea and illustrate the results with specific examples

news droughts news floods and u s disaster relief this paper studies the influence of mass media on u s government response to approximately 5 000 natural disasters occurring between 1968 and 2002 these disasters took nearly 63 000 lives and affected 125 million people per year we show that u s relief depends on whether the disaster occurs at the same time as other newsworthy events such as the olympic games which are obviously unrelated to need we argue that the only plausible explanation of this is that relief decisions are driven by news coverage of disasters and that the other newsworthy material crowds out this news coverage

the vulnerability of price stabilization schemes to speculative attack this paper examines the effects of government attempts to stabilize the prices of commodities by use of buffer stocks agricultural goods subject to supply uncertainty as well as depletable resources are considered in each case it is shown that the resulting rational expectations competitive equilibrium contains a speculative attack a situation where the entire government stock is suddenly purchased by previously inactive speculators the analysis is applied to the historical attempt to peg the gold price which caused the attack of 1968 the insights gained and the methodology developed also apply to the various international agreements to impose bans on commodity prices which have been proposed by the united nations conference on trade and development

disadvantageous oil tariffs and dynamic consistency a large importer who places relatively greater weight on future than current oil consumption will import less oil in the future than if it were able to commit itself in advance to future tariffs and may find itself worse off than if it were unable to impose tariffs at all futures markets and storage modify these adverse effects and may avoid the problem of dynamic inconsistency copyright 1990 by american economic association

financing vs forgiving a debt overhang abstract this paper examines the tradeoffs facing creditors of a country whose debt is large enough that the country cannot attract voluntary new lending if the country is unable to meet its debt service requirements out of current income the creditors have two choices they can finance the country lending at an expected loss in the hope that the country will eventually be able to repay its debt after all or they can forgive reducing the debt level to one that the country can repay the post 1983 debt strategy of the imf and the us has relied on financing but many current calls for debt reform call for forgiveness instead the paper shows that the choice between financing and forgiveness represents a tradeoff financing gives the creditors an option value if the country turns out to do relatively well creditors will not have written down their claims unnecessarily however the burden of debt distorts the country s incentives since the benefits of good performance go largely to creditors rather than itself the paper also shows that the tradeoff itself can be improved if both financing and forgiveness are made contingent on states of nature that the country cannot affect such as oil prices world interest rates etc

sovereign states bondholders committees and the london stock exchange in the nineteenth century 1827 68 new facts and old fictions this paper unpacks the role of foreign bondholders committees in influencing market access following a default during the era before the creation of the british corporation of foreign bondholders cfb in 1868 i argue that many ideas about this period need to be revisited in particular my evidence which uses archival work to describe market microstructures shows the importance of the london stock exchange lse as a court of arbitration i show how the lse general purpose committee set up a system of collective action clauses requiring majority agreement among bondholders to permit market access i argue that unlike what research has argued thus far this created powerful incentives for bondholders to get organized as they did previous models and historical lessons need to be recast copyright 2013 oxford university press

debt levels debt composition and sovereign spreads in emerging and advanced economies this paper studies the relationship between sovereign spreads and the interaction between debt composition and debt levels in advanced and emerging market countries it finds that in emerging market countries there is a significant correlation between spreads and debt levels this correlation however is not statistically significant in countries where most public debt is denominated in local currency in advanced economies the magnitude of the correlation between debt levels and spreads is about one fifth of the corresponding correlation for emerging market economies in eurozone countries however the correlation between spreads and debt ratios is similar to that of emerging market countries the paper also shows that the financial crisis amplified the relationship between spreads and debt levels within the eurozone but had no effect on the relationship between spreads and debt in stand alone countries finally the paper shows that the relationship between debt levels and spreads is amplified by the presence of large net foreign liabilities this amplifying effect of net foreign liabilities is larger in the eurozone than in stand alone advanced economies the paper concludes that debt composition matters and corroborates the original sin hypothesis that rather than being a mere reflection of institutional weakness the presence of foreign currency debt increases financial fragility and leads to suboptimal macroeconomic policies copyright 2013 oxford university press

the limits to fiscal stimulus the paper considers the case for an internationally coordinated further fiscal stimulus during the second half of 2009 although this makes some of the analysis period specific most of the issues and principles considered are timeless for a fiscal stimulus to be both effective there must be idle resources due to a failure of effective demand for it to be desirable there must be no alternative policy instruments including monetary policy for boosting demand there must be no complete financial crowding out and no complete direct crowding out through ricardian equivalence debt neutrality through minsky equivalence or through a high degree of substitutability between private and public exhaustive expenditure in private preferences or production possibilities finally for international coordination to be desirable there must be cross border externalities from national fiscal stimuli the paper considers each of these conditions in turn

rational and self fulfilling balance of payments crises speculative attacks on a pegged exchange rate must sometimes occur ifasset price paths are to be free of abnormal profit opportunities suchattacks are fully rational as they reflect the market s response to aregime breakdown that is inevitable the authors shows that under someexpectations about policy balance of payments crises can also be purely self fulfilling events in such cases even a permanently viableregime may collapse and the economy will possess multiple equilibriacorresponding to different subjective assessments of the probability ofa crisis the behavior of the domestic interest rate will naturally reflect the possibility of a speculative attack copyright 1986 by american economic association

anti hoarding laws a stock condemnation reconsidered economists have regarded anti hoarding laws as irrational reactions to nonexistent monopoly in the storage of grain this paper shows that anti hoarding laws cannot be rationally directed against a monopolistic storer for he will always store less not more than would be stored under competition but seemingly perverse competitive storage in the form of excessive stockholding can arise when a price ceiling distorts the market additional public storage exacerbates this perverse private behavior and may even induce behavior that appears to be active market manipulation under such circumstances anti hoarding laws can be desirable second best measures

credit ratings and the pricing of sovereign debt during the euro crisis this paper identifies the impact of credit rating changes on the sovereign spreads in europe and investigates the macro and financial factors that account for the time varying effects of a given credit rating change we find that changes of ratings are informative significant economically and robust even after controlling for conventional fundamentals a one unit rise in the average credit rating in a scale index of 25 ratings decreases cds spreads by about 45 basis points on average however the association between credit rating changes and spreads follows a complicated non linear pattern dependent on the level of the credit rating applying a non linear spline regression we find high sensitivity large change in spreads for a given change in ratings at the very low end of credit ratings and then a u shape pattern ratings at the moderately low end b and very high end of credit levels above a are fairly insensitive while middle ratings are quite sensitive to credit rating changes with the highest sensitivity at the bb level we also find that european countries had quite similar cds responses to credit rating changes during the pre crisis period but that large differences emerged between the now highlysensitive giips group and other european country groupings eu and euro area excluding giips and the non eu area we also find that contagion from changing the ranking of the giips on other euro countries disappears when own country credit rating changes are taken into account in contrast a decline in the credit rating in the giips area is transmitted as a decline in the cds spread of non euro eu which may be deemed as a substitute asset that increases in demand when the perceived risk of giips sovereign debt increases

sovereign debt as intertemporal barter author s kletzer kenneth m wright brian d abstract borrowing and lending between sovereign parties is modeled as intertemporal barter that smoothes the consumption of a risk averse party subject to endowment shocks the surplus anticipated in the relationship offers sufficient incentive for cooperation by all parties including any other competitive agents who are potential lenders to the sovereign the sole punishments consist of renegotiation proof changes in the path of future payments we show that intertemporal trade can be sustained in the absence of any exogenous enforcement of lending relationships whatsoever that is borrowing and lending are possible under anarchy and are supported by punishments that consist of cheating any cheater long term implicit relationships may be fulfilled as the continual renegotiation of simple incomplete short term loans the analysis suggests that the crucial role of the explicit loan contract is the identification of the relationship and the parties involved

market response to policy initiatives during the global financial crisis abstract this paper examines the impact of macroeconomic and financial sector policy announcements in the united states the united kingdom the euro area and japan on interbank credit and liquidity risk premia during the recent crisis overall policy interventions were associated with a reduction in interbank risk premia most significantly for recapitalization programs by contrast decisions to bail out individual banks in an ad hoc manner or let them fail were accompanied by a significant rise in interbank risk premia most policy announcements had international spillovers these results are broadly robust to using alternative measures of financial distress and varying the size of the event window

international commodity agreements design and performance abstract this article traces the design and performance of the five currently or recently active international commodity agreements icas in cocoa coffee natural rubber sugar and tin following detailed discussion of each of these the author makes three observations that icas can only be successful provided that they command a consensus in their industries that existing agreements are not robust enough with regard to exchange rates and that existing agreements are poorly drafted the author argues that the collapse of the tin agreement in october 1985 may have marked the end of the postwar chapter in the commodity intervention story he finds it improbable that new icas will emerge and suggests instead that more of the existing agreements will lapse

energy conservation nudges and environmentalist ideology evidence from a randomized residential electricity field experiment nudges are being widely promoted to encourage energy conservation we show that while the electricity conservation nudge of providing feedback to households on own and peers home electricity usage works with liberals it can backfire with conservatives our regression estimates predict that a democratic household that pays for electricity from renewable sources that donates to environmental groups and that lives in a liberal neighborhood reduces its consumption by 3 percent in response to this nudge a republican household that does not pay for electricity from renewable sources and that does not donate to environmental groups increases its consumption by 1 percent

debt restructuring and economic recovery analysing the argentine swap when argentine sovereign default in december 2001 led to a collapse of the peso the burden of dollar debt became demonstrably unsustainable but it was not clear what restructuring was feasible nor when eventually in 2005 after a delay of more than three years a super majority of creditors accepted a swap that essentially involved the pesification of dollar liabilities with the imf not playing its customary role in arranging a swap we consider whether a bilateral bargaining approach can help explain the final settlement and the delay in achieving it we find that the swap broadly corresponds to a bargaining outcome where substantial delay occurred for both political and economic reasons even after political legitimacy was assured by general elections negotiators seeking a sustainable outcome at a time of deep recession profound currency under valuation and high sovereign spreads realised it was better to wait before settling other factors discussed include the definition of sustainability criteria the effect of inter creditor conflict and the role of third parties in promoting good faith bargaining we suggest that while these issues need further investigation there are institutional changes that could make them less problematic

tariffs as insurance optimal commercial policy when domestic markets are incomplete free trade is not optimal for a small country that faces uncertain terms of trade if some factors are immobile ex post and markets for contingent claims are incomplete the government can improve social welfare by using commercial policy that serves as a partial substitute for missing insurance markets using a combination of analytical and simulation techniques we demonstrate that optimal policy for this purpose will often have an anti trade bias we also show that the usual preference by economists for factor or product taxes and subsidies over tariffs and export subsidies may not be justified in this context this abstract was borrowed from another version of this item

capital flight to germany two alternative measures abstract we use two measures to study two capital flight channels for germany one measure is based on the concept of trade misinvoicing and one on net claims and liabilities in the eurosystem of central banks for both measures we propose refinements to enhance the assessment of capital flight we find that capital flight towards germany via these two channels has been quite sizable in the recent decade and can tally to about 2 of gdp annually regarding their determinants we show that the two capital flight measures are driven by both common and measure specific factors traditional determinants such as covered interest differentials only play a limited role while crisis specific factors such as economic policy uncertainty the ecb collateral policy as well as currency misalignment are driving factors of the investors apparent flight to safety behavior

sovereign debt the assessment this article serves as an introduction to two issues of the oxford review of economic policy one entitled sovereign debt understanding bond markets during the eurozone crisis and the second sovereign debt lessons from the past reforms for the future we begin by documenting recent trends in advanced country sovereign indebtedness and reviewing events that preceded the sovereign debt crisis in the eurozone the mechanisms through which rising sovereign debt may impact bond yields economic growth and inflation are discussed and the evidence for such effects is reviewed our discussion highlights that there is no unique threshold beyond which sovereign debt exerts adverse macroeconomic effects and that in order to understand the consequences of a given debt load one must analyse its structure in terms of internal and external creditors currency denomination the time to maturity of the bonds and the legal code governing debt issuance as well as various economic and political constraints measuring the fiscal space of the sovereign we then turn our attention to episodes in which sovereign debt proves excessive and default occurs we review explanations for the protracted and inefficient nature of defaults and describe some lessons from historical studies examining default outcomes in the final part of the paper we discuss proposals for averting future debt crises including jointly issued bonds such as eurobonds contingent convertible bonds and elements of a sovereign debt restructuring mechanism in the course of our discussion we draw on each of the 11 articles included in the two issues of this journal devoted to sovereign debt copyright 2013 oxford university press

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

the eurozone crisis how banks and sovereigns came to be joined at the hip the eurozone sovereign and banking crisis evolved in three phases following the onset of the subprime tremors in july 2007 the risk premia spreads on bonds issued by eurozone sovereigns rose from historically low levels but they rose largely in tandem across the eurozone membership along with global banking stresses the rescue of the us investment bank bear stearns in march 2008 oddly enough marked the start of a distinctively european banking crisis accompanied by increased differentiation of countries within the eurozone with the greater expectation of public support for distressed banks the spreads that a sovereign paid tended to rise following evidence of stress in its domestic financial sector this was especially so in countries with lower growth prospects and higher debt burdens but there was as yet no feedback from banks to sovereigns finally as the limits of fiscal support for domestic banks became clearer and coinciding with the nationalization of anglo irish in january 2009 but gathering steam with evidence of the greek sovereign s distress in may 2010 sovereign weaknesses also came to be quickly transmitted to a more pessimistic assessment of the financial sector s prospects creating the potential of mutual destabilization ashoka mody and damiano sandri
