identifying domestic and imported core inflation this paper estimates core inflation in norway identified as that component of inflation that has no long run effect on gdp the model distinguishes explicitly between domestic and imported core inflation the results show that domestic core inflation is the main component of cpi inflation however cpi inflation misrepresents core inflation during some periods the differences are well explained by the other shocks identified in the model in particular the oil price shocks of the 1970s when norway imported inflation and the negative non core supply shocks of the late 1980s which pushed inflation up temporarily relative to core inflation

central bank design abstract starting with a blank slate how could one design the institutions of a central bank for the united states this paper explores the question of how to design a central bank drawing on the relevant economic literature and historical experiences while staying free from concerns about how the fed got to be what it is today or the short term political constraints it has faced at various times the goal is to provide an opinionated overview that puts forward the trade offs associated with different choices and identifies areas where there are clear messages about optimal central bank design

globalization and emerging markets with or without crash we analyze the effects of financial and trade globalization on the likelihood of financial crashes in emerging markets while trade globalization always makes crashes less likely financial globalization may make them more likely especially when trade costs are high pessimistic expectations can be self fulfilling and lead to a collapse in demand for goods and assets such a crash comes with a current account reversal and drops in income and investment lower income countries are more prone to such demand based financial crises a quantitative evaluation shows our model is consistent with the main stylized facts of financial crashes in emerging markets

long run identification in a fractionally integrated system we propose an extension of structural fractionally integrated vector autoregressive models that avoids certain undesirable effects on the impulse responses that occur if long run identification restrictions are imposed we derive the model s granger representation and investigate the effects of long run restrictions simulations illustrate that enforcing integer integration orders can have severe consequences for impulse responses in a system of u s real output and aggregate prices the effects of structural shocks strongly depend on the specification of the integration orders in the statistically preferred fractional model shocks that are typically interpreted as demand disturbances have a very brief influence on gdp supplementary materials for this article are available online

sovereign default risk and the u s equity market i develop a two country general equilibrium model with firms governments and endogenous default decisions this paper shows that the risk of sovereign default abroad is important in the explanation of the level and the volatility of u s equity returns the intuition is that negative economic shocks deteriorate the fiscal situation of foreign governments thereby increasing the risk of a sovereign default that would trigger a local contraction in economic growth the rise in the risk of an economic slowdown abroad amplifies the direct eect of these shocks on the level and the volatility of equity returns in the u s through i a decrease in the present value of future firm earnings due to the unfavorable adjustment of the real exchange rate for u s exporters and ii a fall in u s equity prices that originates from the investors incentive to rebalance their portfolio towards risk free securities the amplification eect is strongest during periods of financial distress when the risk of corporate default is high in the u s a structural estimation of the model provides strong support for this prediction using monthly data for brazil and the u s over the period 1994 2008

introduction imperfect information and rural credit markets puzzles and policy perspectives rural credit markets have been at the center of policy intervention in developing countries over the past forty years many governments supported by multilateral and bilateral aid agencies have devoted considerable resources to supplying cheap credit to farmers in a myriad of institutional settings the results of many of these interventions have been disappointing and one explanation for this must be that they were based on an inadequate understanding of the workings of rural credit markets the articles in this symposium issue are devoted to empirical and theoretical investigations of rural credit markets in the framework of the imperfect information paradigm the authors show how this framework is useful not only in explaining puzzling features of these markets but also in providing a policy perspective to assess the successes and failures of specific interventions

learning about a new technology pineapple in ghana this paper investigates the role of social learning in the diffusion of a new agri cultural technology in ghana we use unique data on farmers communication patterns to define each individual s information neighborhood conditional on many potentially confounding variables we find evidence that farmers adjust their inputs to align with those of their information neighbors who were surpris ingly successful in previous periods the relationship of these input adjustments to experience further indicates the presence of social learning in addition applying the same method to input choices for another crop of known technol ogy correctly indicates an absence of social learning effects jel d83 013 033 q16

assessing the functioning of land rental markets in ethiopia although a large theoretical literature discusses the possible inefficiency of sharecropping contracts the empirical evidence on this phenomenon has been ambiguous at best household level fixed effect estimates from about 8 500 plots operated by households that own and sharecrop land in the ethiopian highlands provide support for the hypothesis of marshallian inefficiency at the same time a factor adjustment model suggests that the extent to which rental markets allow households to attain their desired operational holding size is extremely limited our analysis points towards factor market imperfections no rental for oxen lack of alternative employment opportunities and tenure insecurity as possible reasons underlying such behavior suggesting that rather than worrying almost exclusively about marshallian inefficiency it is equally warranted to give due attention to the policy framework within which land rental markets operate

social networks and technology adoption in northern mozambique despite their potentially strong impact on poverty agricultural innovations are often adopted slowly using a unique household dataset on sunflower adoption in mozambique we analyse whether and how individual adoption decisions depend upon the choices of others in the same social networks since farmers anticipate that they will share information with others we expect farmers to be more likely to adopt when they know many other adopters dynamic considerations however suggest that farmers who know many adopters might strategically delay adoption to free ride on the information gathered by others we present empirical evidence that shows that the relationship between the probability of adoption and the number of known adopters is shaped as an inverse u in line with information sharing the network effect is stronger for farmers who report discussing agriculture with others the data contains information which is needed to ameliorate the identification issues that commonly arise in this context in particular social networks are precisely identified and in addition we can control for village heterogeneity and endogenous group formation

measures of technology and the business cycle empirical evidence on the relationship between technology shocks and e g hours worked hinges crucially on the identification of the unobservable technological progress in this paper we study different measures of technology in order to find out i to what extent they capture the same underlying phenomenon and ii whether the implications for macroeconomic theory are robust across the approaches several versions of the productions function approach and structural var models are investigated our main finding is that the different technology measures are highly correlated however the exact formulation of the identifying restrictions seems to matter for the results while we replicate the standard finding of a strongly procyclical solow residual all other measures of technology are either acyclical or countercyclical

can social protection work in africa the impact of ethiopia s productive safety net programme abstractthis study evaluates a large social protection program in rural ethiopia the productive safety net programme psnp the effectiveness of the psnp is of interest because the program was implemented at scale in one of africa s poorest countries which has limited physical and communications infrastructure and scarce administrative resources using longitudinal survey data collected in 2006 2008 and 2010 at the household and locality levels we employ an extension of the propensity score matching method to continuous treatments to estimate the impact of transfers from the psnp and a separate program on household food security against the formidable background of rising food prices and widespread drought participation in the public works component of the psnp has modest effects the psnp reduced the length of the last hungry season by 1 29 months among households that received transfers for 5 years compared to eligible households that received almost nothing five years of participation raises l

risk sharing networks and insurance against illness most risk sharing tests on developing country data are conducted at the level of the village generally the full risk sharing hypothesis is rejected this paper uses detailed data on all insurance networks within a village in tanzania networks are not clustered but largely overlapping we test whether full risk sharing occurs within these networks while village level full insurance cannot be rejected for food consumption we find evidence consistent with at least partial insurance of non food consumption via networks

some evidence of smooth transition nonlinearity in colombian inflation evidence of smooth transition autoregressive star representations is found in two out of three time series of different measures of annual inflation in colombia during this decade for monthly data the star type nonlinearities are asymmetric for inflation computed as the variation of cpi while for a measure of core inflation are symmetric thus lstar and estar models were respectively estimated no evidence of nonlinearity is found for traded goods inflation given the local dynamic properties of the estimated lstar model only positive shocks to prices could shift negative accelerating inflation rate from the upper to the lower regime by the same token only stochastic shocks can move the core accelerating inflation rate from the outer regime to the middle one but the explosive nature of this regime will impulse the accelerating inflation rate to the outer one

permanent and transitory movements in labor income an explanation for excess smoothness in consumption many have argued that if labor income is difference stationary the permanent income hypothesis predicts that consumption should be relatively volatile in u s aggregate data labor income is well characterized as having a unit root however consumption turns out to be relatively smooth this anomaly is known as deaton s paradox i resolve deaton s paradox by providing decompositions of labor income into permanent and transitory components these preserve the univariate dynamic properties of labor income however when agents distinguish permanent and transitory movements in their labor income as the rational expectations hypothesis asserts they should the permanent income hypothesis correctly predicts the observed smoothness in consumption

credit markets in northern nigeria credit as insurance in a rural economy this article addresses the issues of imcomplete markets and imperfect information in the context of credit markets in rural northern nigeria in much recent theoretical literature the problems of moral hazard and adverse selection are assumed to be decisive for the organization of agrarian institutions in contrast it is found that in the four villages surveyed credit transactions take advantage of the free flow of information within rural communities information asymmetries between borrower and lender are unimportant and their institutional consequences the use of collateral and interlinked contracts are absent credit transactions play a direct role in pooling risk between households through the use of contracts in which the repayment owed by the borrower depends on the realization of random production shocks by both the borrower and the lender

is it punishment sovereign defaults and the decline in trade sovereign defaults are associated with declines in defaulting countries trade are these declines the result of trade sanctions as the trade sanctions argument of sovereign borrowing would suggest we devise an empirical strategy to evaluate this issue based on the idea that if trade sanctions are causing the declines bilateral trade with creditor countries should fall more than trade with other countries we find that this is not the case the analysis does not yield much evidence of broader punishment strategies including a league of major creditors either these results contradict the predictions of the trade sanctions theory of sovereign borrowing

risk and insurance in a rural credit market an empirical investigation in northern nigeria credit contracts play a direct role in pooling risk between households in northern nigeria repayments owed by borrowers depend on realizations of random shocks by both borrowers and lenders the paper develops two models of state contingent loans the first is a competitive equilibrium in perfectly enforceable contracts the second permits imperfect information and equilibrium default estimates of both models indicate that quantitatively important state contingent payments are embedded in these loan transactions but that a fully efficient risk pooling equilibrium is not achieved the research is based on a year long survey in zaria nigeria conducted by the author

a combined measure of uk core inflation estimates this article estimates uk core inflation in a structural vector autoregression var framework while building on the work of quah and vahey 1995 we extend their two variable var model to allow for different dynamics depending on the nature of the shocks that potentially influence the process of core inflation we also construct a combined measure of core inflation estimates on the basis of their reliabilities empirical evidence shows that the new measures demonstrate marked improvement in their eligibility to serve as core inflation estimators furthermore the combined measure is shown to perform best it appears that the conventional core measures such as the retail prices excluding mortgage interest payments rpix and the harmonized index of consumer prices hicp inflation series are not successful in capturing the underlying trend of inflation casting some doubt on their current use in the making of monetary policy decisions

descomposicion historica de la inflacion en peru distinguiendo entre choques de demanda y choques de oferta this paper analyzes and distinguishes the role and importance of the shocks related to the aggregate demand and aggregate supply on the behavior of the peruvian inflation during the period 1997 1 2009 2 we use the methodology based on structural vector autoregressive svar models using a long run identification based on blanchard and quah 1989 which allows to obtain the historical decomposition of the annual inflation unlike salas 2009 this paper uses a more simple model of aggregate demand and aggregate supply and a larger sample the results show that the behavior of inflation was largely explained for shocks related to the aggregate demand side in comparison with aggregate supply shocks furthermore the results of the variance decomposition of the prediction error show that in the short and long term the shocks of the demand side explain around 70 and 60 of the movements of the inflation the results are robust to the inclusion of different variables in the set of information

tenure insecurity gender low cost land certification and land rental market participation in ethiopia abstract there is a renewed interest in whether land reforms can contribute to market development and poverty reduction in africa this paper assesses effects on the allocative efficiency of the land rental market of the low cost approach to land registration and certification of restricted property rights that was implemented in ethiopia in the late 1990s four rounds of a balanced household panel from 16 villages in northern ethiopia are analysed showing that land certification initially enhanced land rental market participation of potential tenant and landlord households especially those that are headed by females

inflation measurement and the ecb s pursuit of price stability a first assessment as part of its monetary policy strategy announced in 1998 the ecb provided a quantitative definition of its price stability objective as an annual rate of increase in the harmonized index of consumer prices hicp of below 2 0 percent this paper takes a measurement perspective in evaluating the ecb s quest for price stability during the first years of monetary we consider the following questions first what is the hicp designed to measure and how accurate is it in terms of its stated objective second how accurate are the traditional exclusion type measures of core inflation derived from the hicp and more importantly is there evidence that less traditional measures of core inflation might be useful to the ecb and third is there any sense in which the ecb s definition of price stability in terms of a 2 0 percent limit on hicp inflation can be said to be too low from a measurement perspective we conclude that the conceptual underpinnings of the hicp remain sufficiently vague that it is difficult to compare with other indexes or come to any hard conclusions about its accuracy it is possible that the hicp is as susceptible to the biases that are known to affect other measures of inflation at the consumer or household level and if forced to quantify potential bias a point estimate of 1 0 percent strikes us as reasonable potential bias of this magnitude in conjunction with the inherent noisiness of the headline number and the well known aversion of central bankers to deflation argues for a modest upward redefinition of the rate of hicp inflation consistent with price stability finally we show that the ecb would be well served by increasing their use of nontraditional core inflation measures

the dynamic effects of aggregate demand and supply disturbances we interpret fluctuations in gnp and unemployment as due to two types of disturbances disturbances that have a permanent effect on output and disturbances that do not we interpret the first as supply disturbances the second as demand disturbances demand disturbances have a hump shaped mirror image effect on output and unemployment the effect of supply disturbances on output increases steadily over time peaking after two years and reaching a plateau after five years

signalling with many signals this paper examines a market with asymmetric information where there are many signals available and where both the costs of signaling and the product value may depend on many privately known characteristics under a weak condition on the relationship between the marginal cost of increasing the signals and the product value a separating set exists whereby the value of every seller s product is inferred from the seller s optimal choice of signals the separating set constructed is pareto dominant and corresponds to recently proposed equilibrium notions in signaling and screening models copyright 1987 by the econometric society

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 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

sovereign defaults by currency denomination abstract this paper explores the drivers of sovereign default in 100 countries over the period 1996 2012 we build a new data set of sovereign defaults and find that default events for local and foreign currency bonds are equally likely however governments default under different economic and financial conditions depending on the currency in which bonds are issued the explained variation in default probability rises from 43 to 62 when we account for differences in currency denomination we also provide evidence that global factors and market sentiment which are known to drive sovereign spreads do not help explain the probability of sovereign default hence these factors appear to affect the price of sovereign credit risk although not the risk itself

learning by doing and learning from others human capital and technical change in agriculture household level panel data from a nationally representative sample of rural indian households describing the adoption and profitability of high yielding seed varieties hyvs associated with the green revolution are used to test the implications of a model incorporating learning by doing and learning spillovers the estimates indicate that i imperfect knowledge about the management of the new seeds was a significant barrier to adoption ii this barrier diminished as farmer experience with the new technologies increased iii own experience and neighbors experience with hyvs significantly increased hyv profitability and iv farmers do not fully incorporate the village returns to learning in making adoption decisions

permanent transitory decompositions and traditional measures of core inflation abstract the aim of this paper is twofold first after defining core inflation in line with the recent literature as the long run component of the rate of change of the consumer price index cpi we address the general problem of establishing a set of conditions under which given the assumption of inflation as an i 1 process it is possible to identify an indicator of trend inflation we show that some criteria recently proposed in the literature economics letters 75 2002 17 are unnecessarily restrictive second an empirical investigation for the period 1983 2001 reveals that these conditions are met in the us economy both for the traditional measure of core inflation which is obtained by subtracting food and energy components from cpi and for the weighted median of cpi proposed by monetary policy university of chicago press for nber 1994 261 these conclusions hold for a measure of core inflation based on the year on year rate of change of the core index and thus we provide some motivation for this choice

globalization and risk sharing we study the effects of globalization on risk sharing and welfare like the previous literature we assume that governments cannot commit to enforce the repayment of debts owed by their citizens unlike the previous literature we assume that governments cannot discriminate between domestic and foreign creditors when enforcing debt payments this creates novel interactions between domestic and international trade in assets i increases in domestic trade raise the benefits of enforcement and facilitate international trade in fact in our set up countries can obtain international risk sharing even in the absence of default penalties ii increases in foreign trade raise the costs of enforcement and hamper domestic trade as a result globalization may worsen domestic risk sharing and lower welfare we show how these effects depend on various characteristics of tradable goods and explore the roles of borrowing limits debt renegotiations and trade policy

repatriation of debt in the euro crisis with the beginning of the euro crisis the long standing trend of european financial integration reversed investors unwound cross border positions of debt obligations and increased holdings of locally issued debt in other words debt obligations were repatriated we use data on bank portfolios to document three new empirical regularities of the financial disintegration i repatriation affected mainly debt of crisis countries ii repatriation affected mainly public debt iii the public debt of crisis countries that was not repatriated was reallocated to large and politically influential countries within the euro area we read these results in light of standard theories of cross border portfolio allocation and argue that the sum of these patterns constitutes evidence for the secondary market theory of public debt

social networks and factor markets panel data evidence from ethiopia we investigate the role of an indigenous social network in ethiopia the iddir in facilitating factor market transactions among smallholder farmers we use detailed longitudinal household survey data and employ fixed effects estimation approaches to identify the effect of iddir membership on factor market transactions among farmers we find that joining an iddir network improves households access to land labour and credit transactions our findings also hint that iddir networks may crowd out borrowing from local moneylenders locally referred as arata abedari a relatively expensive credit source these results suggest that non market institutions can play crucial roles in facilitating market transactions

sovereign defaults information investment and credit abstract why would a sovereign government immune from bankruptcy procedures and with few assets that could be seized in the event of a default ever repay foreign creditors and correspondingly why do foreign creditors lend to sovereigns this paper finds general conditions under which even in the absence of sanctions lending to sovereigns can emerge in a single shot game furthermore it shows that positive borrowing can be sustained both in pooling and separating equilibria in this way it makes clear that neither sanctions nor reputation considerations the two classical explanations are necessary to enforce repayment information revelation is the crucial mechanism for these results the repayment default decision is interpreted as a signal used by the government to communicate information to domestic and foreign agents about the fundamentals of the economy governments repay to affect agents expectations about them a default through its effect on expectations about fundamentals can generate a decline in foreign and domestic investment and a credit crunch in domestic credit markets governments repay to avoid these costs but may default in equilibrium when hit by a negative shock

social networks and credit access in indonesia abstract in this paper we investigate how family and community networks affect an individual s access to credit institutions using new data from the indonesia family life surveys our theoretical framework emphasizes the family and community s role in providing information thus lowering the search costs of the borrower and monitoring and enforcement costs for the lender from our empirical results community and family networks are important in knowing a place to borrow as well as for loan approval consistent with an information based explanation of networks family and community networks have a larger impact on credit awareness of new credit institutions with a lower impact on awareness of established credit sources interestingly we find that women benefit from participating in community networks more than men there is no evidence that the rich benefit from community networks more than the poor our results on the benefits from participation in the community network are robust to the inclusion of community fixed effects

a simple adaptive measure of core inflation this paper proposes a new measure of core inflation and compares it with several existing measures the new measure is adaptive and is designed to track sudden and persistent movements in inflation such as those arising from changes in monetary policy regimes the adaptive measure filters out transients more effectively than existing measures and it is a superior predictor of locally mean reverting components of inflation

a note on modelling core inflation for the uk using a new dynamic factor estimation method and a large disaggregated price index dataset abstract the term core inflation is widely used by academics and central bankers though there is no widely accepted definition or agreed method of measuring it in this paper we propose a new measure of core inflation which is atheoretical but assumes factor structure for the disaggregated price indices which underlie most constructed measures of inflation we show that the measure of core inflation obtained has added predictive ability for inflation in the uk over a relatively long evaluation period

official debt restructurings and development abstract despite the frequency of official debt restructurings little systematic evidence has been produced on their characteristics and implications using a dataset covering more than 400 paris club agreements this paper fills that gap it provides a comprehensive description of the evolving characteristics of these operations and studies their impact on debtors the progressive introduction of new terms of treatment gradually turned the paris club from an institution primarily concerned with preserving creditors claims into an instrument to foster development in the world s poorer nations among other objectives our study finds that more generous restructuring conditions involving nominal relief are associated with an acceleration of per capita gdp growth and with a reduction in poverty and inequality we also find that countries receiving nominal relief tend to receive lower aid flows subsequently the opposite being the case for countries receiving high reductions in the net present value of their obligations but no nominal haircuts

sovereign debt repurchases no cure for overhang troubled debtor countries do not gain by repurchasing external bank debt at market discount even if a buyback would stimulate investment by relieving debt overhang the reason is that buybacks allow creditors to reap more than 100 percent of any efficiency gains that might result from increased investment we show that open market buybacks provide a benchmark for evaluating more complex negotiated buyback deals by comparing any given deal with a hypothetical market buyback of the same size one can derive upper and lower bounds on the gain to the country we apply our model to the 1990 mexican debt deal

debt and default in the 1930s causes and consequences abstract this paper studies interwar experience with external debt and default it begins with a description of the contours of international borrowing and lending in the 1920s we then use some empirical models from recent literature on the 1970s to describe the interwar data macroeconomic variables for over 20 countries are related to cross section variations in borrowing and debt during the period from the end of the 1920s to 1938 the paper then considers the incidence and correlates of sovereign default for 1934 1938 using regression to determine the association between standard measures of economic structure and performance and subsequent interruptions to debt service such variables as the magnitude of the debt burden the deterioration of the terms of trade during the great depression and the stance of monetary and fiscal policies provide a remarkably accurate explanation of the incidence of default we go on to provide a long run perspective on default and on the remedies available to creditors the provisions of loan contracts are reviewed with an eye toward analyzing the scope for renegotiation the discussion emphasizes the contrast between the regime of bond finance that prevalied in the interwar years and the current regime of bank lending we analyze the roles of governments banks and bondholders protective committees in the negotiation process we then present new estimates of the ex post realized rates of return on british and american foreign lending in the 1920s this empirical analysis uncovers a striking contrast in the returns realized on loans floated in the two countries while the nominal internal rate of return on dollar loans was less than 1 per annum the comparable return on sterling loans was in excess of 5 the paper concludes with a discussion of factors which help to account for this dramatic difference

financial systems in northern thai villages field research attempted to measure the risky environments the information structures the institutions and the risk response mechanisms of ten villages in northern thailand various key features are then modeled in an abstract but realistic way either with a full information risk sharing model or an information constrained version of the same model observations from some of the villages seem consistent with one or the other of these models but in many of the villages one is left with risk response variations across households which suggest that pareto improvements are possible

kinship and financial networks formal financial access and risk reduction kinship networks are beneficial for smoothing consumption and investment but the channels are not well understood we study the financing devices used for consumption and investment by thai households households that are connected to banks achieve significantly better consumption smoothing than unconnected households indirect connections via inter household borrowing are as effective as direct borrowing investment appears to be facilitated by kinship households with kin in the village display reduced sensitivity of investment to income while connections to banks do not significantly reduce sensitivity kin may act as implicit collateral permitting borrowing that would violate repayment constraints in its absence

the impact of ethiopia s productive safety net programme and its linkages abstract this paper assesses the impact of ethiopia s productive safety nets programme psnp the largest social protection programme in sub saharan africa outside of south africa using propensity score matching techniques we find that the programme has little impact on participants on average due in part to transfer levels that fell far below programme targets participants with access to both the psnp and packages of agricultural support are more likely to be food secure to borrow for productive purposes use improved agricultural technologies and operate non farm own business activities however beneficiaries did not experience faster asset growth

federal reserve information and the behavior of interest rates this paper tests for the existence of asymmetric information between the federal reserve and the public by examining federal reserve and commercial inflation forecasts it demonstrates that the federal reserve has considerable information about inflation beyond what is known to commercial forecasters it also shows that monetary policy actions provide signals of the federal reserve s information and that commercial forecasters modify their forecasts in response to those signals these findings may explain why long term interest rates typically rise in response to shifts to tighter monetary policy jel e52 e43 d82 asymmetric information between the federal reserve and the public is a phenomenon that is often posited but rarely tested numerous models of central bank behavior for example show that the existence of asymmetric information has important implications for the effectiveness of policy and the consequences of dynamic inconsistency yet there

ex ante implications of sovereign default i study how the possibility of default on external debts affects other capital allocation decisions in a small open economy in the model default has an option value derived from the randomization over ex post default regimes which depends on country specific productivity shocks this feature of default reduces incentives for ex ante diversification which would reduce exposure to the productivity shock as a result if the economys debt to capital ratio is allowed to cross a fixed threshold identified in the model the unique equilibrium exhibits an allocation of capital that is less productive in expectation and more volatile than in a benchmark model without default the model therefore captures a number of salient features of emerging and less developed countries where low levels of international risk sharing have gone hand in hand with frequent and recurring default events

do underlying measures of inflation outperform headline rates evidence from australian data many central banks often focus on underlying measures of inflation when assessing inflation trends this paper compares the accuracy of underlying measures of inflation relative to the headline rates by using australia data it is found that the underlying measures did have smaller errors in predicting the long term trend in inflation than the quarterly headline rate due to the volatility in the headline rate as compared to the year ended headline rate the statistical test results however support only the measure of market prices excluding volatile items not the others there is some weak evidence of the weighted median measure outperforming the headline rate in the sub period after 1993 with respect to directional accuracy the test statistics cannot reject the null hypothesis of an equal probability correctly predicting the moving direction of the inflation trend though the headline rates have a higher probability

credit constraints and agricultural productivity evidence from rural rwanda while potentially negative impacts of credit constraints on economic development have long been discussed conceptually empirical evidence for africa remains limited we use a direct elicitation approach on a national sample of rwandan rural households to empirically assess the extent and nature of credit rationing in the semi formal sector and its impact using an endogenous switching model elimination of all constraints could increase output by some 17 per cent implications for policy and research are spelled out

social connections and group banking lending to the poor is expensive due to high screening monitoring and enforcement costs group lending advocates believe lenders overcome this by harnessing social connections using data from finca peru i exploit a quasi random group formation process to find evidence of peers successfully monitoring and enforcing joint liability loans individuals with stronger social connections to their fellow group members i e either living closer or being of a similar culture have higher repayment and higher savings furthermore i observe direct evidence that relationships deteriorate after default and that through successful monitoring individuals know who to punish and who not to punish after default

peasant household behaviour with missing markets some paradoxes explained a model of peasant household behavior under varying degrees of household specific food and labor market failures is constructed to show that these structural features can explain several well known patterns of peasant response which have often been attributed to peculiar motives presumed specific to peasants the model explains sluggish response to cash crops prices and high instability in perceived food and labor scarcities the key role of manufactured consumer goods prices in stimulating peasants effort in cash crops production the effectiveness of taxation as opposed to incentives in stimulating cash crops production and the key role of technological change in food production to enhance cash crop production results are obtained analytically in the case of one market failure and by numerical simulation with more than one

development and social capital abstract this paper examines social capital and its relation with economic development we focus on the role that interpersonal relationships play in social exchange whether through the market or through the provision of public goods by facilitating search and trust social capital can increase the efficiency of social exchange where formal institutions are weak but the benefits from social capital are likely to be unequally distributed given these features documenting empirically the benefits of social capital is complicated by the presence of negative and positive externalities and by the existence of leadership and group effects lessons for development policy are drawn at the end

do core inflation measures help forecast inflation out of sample evidence from french data abstract this paper compares the ability of four indicators of underlying or core inflation to forecast inflation in the french case though most indicators granger cause inflation results from out of sample tests of forecast accuracy are less compelling the results nevertheless seem to give some empirical support to trimmed mean indicators

a core inflation indicator for the euro area this paper proposes a new core inflation indicator for the euro area obtained by cleaning monthly price changes from short run volatility idiosyncratic and measurement errors we use a factor model to project monthly inflation on a large panel of time series exploiting multivariate information we obtain a satisfactory degree of smoothing without using backward looking moving averages which induce a time delay in the signal the indicator forecasts inflation and is a useful tool for policy makers it outperforms other commonly used predictors at 6 months and longer horizons it tracks past policy interventions of the ecb

group based funeral insurance in ethiopia and tanzania a funeral is a costly occasion this paper studies indigenous insurance institutions developed to cope with the high costs of funerals based on evidence from rural areas in tanzania and ethiopia these institutions are based on well defined rules and regulations often offering premium based insurance for funeral expenses increasingly they are also offering other forms of insurance and credit to cope with hardship the paper argues that the characteristics and inclusiveness of these institutions make them well placed as models to broaden insurance provision and other developmental activities in these communities the history of these institutions is characterised by a resistance to attempts of political capture and helps to understand their apparent resistance to engage more broadly with ngos and government agencies as a result any attempt to expand their activities will have to be done cautiously

sovereign default risk and commitment for fiscal adjustment abstract this paper studies fiscal policy in a model of sovereign debt and default a time inconsistency problem arises since the price of past debt cannot be affected by current fiscal policy and governments cannot credibly commit to a certain path of tax rates debtor countries choose suboptimally low fiscal adjustments an international organization capable of designing a contract that coaxes debtors into a tougher fiscal stance via the provision of cheap senior lending in times of crisis can work as a commitment device and improve social welfare

imperfect information screening and the costs of informal lending a study of a rural credit market in pakistan many governments have perceived the rural moneylender as usurious this article takes a first step toward directly testing the validity of this view in a study of services costs and charges of fourteen informal market moneylenders and their clients in chambar pakistan the article examines whether the high implicit interest rates charged reflect the actual costs of operating in that market estimates of the resource costs incurred by informal lenders for screening pursuing delinquent loans overhead and cost of capital including unrecoverable loans suggest that lenders charges are equal to their average cost of lending but exceed their marginal cost this finding is consistent with the view that the informal credit market is characterized by excess capacity and monopolistic competition in the presence of imperfect information

markets market failures and development a central question in development economics is how can we account for differences in the levels of income and the rates of growth between the developed and less developed economies in the 1950s and 1960s there was a standard answer to this question the poor are just like the rich except they are poorer they have less human and nonhuman capital there was an immediate prescription for this diagnosis increase the resources of ldcs either by transferring capital to them either direct aid or education or by encouraging them to save more today these answers seem less convincing that they did two decades ago if the problem were primarily a shortage of physical capital the return to capital should be much higher in ldcs than in developed countries and the natural avarice of capitalists would lead to a flow of capital from the more developed to the less developed economies see howard pack 1984 and my 1988 paper if the problem were primarily a shortage of human capital then the educated in ldcs should receive a higher absolute as well as relative income than the educated in more developed economies how then can we account for high levels of unemployment among the educated and the migration of the educated from ldcs to more developed economies moreover the predictions of the standard neoclassical growth model of a convergence of growth rates in per capita income with permanent differences in per capita consumption being explained by differences in savings rates and reproduction rates do not seem to have been borne out these observations suggest that the ldcs differ from the developed countries in at least some other important respects and this view is corroborated by those studies which have looked at the productivity of similar plants operating in developed and less developed economies see pack 1984 1987 the difference can be attributed perhaps tautologically to differences in economic organization to how individuals factors of production interact and to the institutions which mediate those interactions among the most important of these institutions are markets it is by now well recognized that there are many instances of market failures in more developed economies see bruce greenwald and myself 1986 in some cases market failures may be ameliorated by nonmarket institutions if for instance capital markets do not function well perfectly if only because of costly and imperfect information nonmarket institutions internal capital markets within large conglomerates may develop market failure is more prevalent in ldcs and the nonmarket institutions that ameliorate its consequences are at least in many instances less successful in doing so the objective of this paper is to explore the causes and consequences of these market failures and the failure of private nonmarket solutions and to suggest possible roles for government intervention tdiscussants anne 0 krueger duke university stanley fischer world bank

using an error correction model to test whether endogenous long run growth exists abstract a major empirical interest in growth studies is whether permanent changes in economic fundamentals affect the long run growth rate or not however a direct time series analysis of this hypothesis may not always be feasible because the permanence of many such changes is rather questionable this paper explains why examining the long run effects of temporary changes in investment share on per capita output provides indirectly the answer regarding the effects of possibly hypothetical permanent changes in investment share when log per capita output and log per capita investment are cointegrated applying the proposed method to the post war data of major industrial countries it is found that a disturbance to investment share does not produce a positive long run effect in each of the three countries france japan and the united kingdom in which log per capita output and log per capita investment are cointegrated the evidence is unfavorable to the class of endogenous growth models

forecasting core inflation the case of south africa forecasting and estimating core inflation has recently gained attention especially for inflation targeting countries following research showing that targeting headline inflation may not be optimal a central bank can miss the signal due to the noise despite its importance there is sparse literature on estimating and forecasting core inflation in south africa with the focus still on measuring core inflation this paper emphasises predicting core inflation using large time varying parameter vector autoregressive models tvp vars factor augmented var and structural break models using quarterly data from 1981q1 to 2013q4 we use mean squared forecast errors msfe and predictive likelihoods to evaluate the forecasts in general we find that i small tvp vars consistently outperform all other models ii models where the errors are heteroscedastic do better than models with homoscedastic errors iii models assuming that the forgetting factor remains 0 99 throughout the forecast period outperforms models that allow for the forgetting factors to change with time and iv allowing for structural break does not improve the predictability of core inflation overall our results imply that additional information on the growth rate of the economy and interest rate is sufficient to forecast core inflation accurately but the relationship between these three variables needs to be modelled in a time varying nonlinear fashion

can social cohesion be harnessed to repair market failures evidence from group lending in guatemala the success of group lending in developing countries has been attributed to the ability of the institution to mitigate asymmetric information problems in credit markets previous research has offered a number of explanations for this phenomenon social ties between borrowing group members internal group pressure to repay loans and peer monitoring this research presents empirical tests on borrowing group data from guatemala which indicate that peer monitoring significantly effects borrowing group performance through stimulating intra group insurance group pressure is found to have a small effect in deterring moral hazard while the effect of social ties among members is statistically insignificant

measuring core inflation in this paper we argue that measured rpi inflation is conceptually mismatched with core inflation the difference is more than just measurement error we propose a technique for measuring core inflation based on an explicit long run economic hypothesis core inflation is defined as that component of measured inflation that has no medium to long run impact on real output a notion that is consistent with the vertical long run phillips curve interpretation of the co movement in inflation and output we construct a measure of core inflation by placing dynamic restrictions on a vector autoregression var system

gains from trade and the sovereign bond market abstract increasing international flows of goods services and financial assets have been shown to increase a country s welfare through various channels this paper studies how a country s access to a bond market affects its welfare gains from international trade we do so by incorporating a sovereign bond market into a simple armington 1969 s trade model while standard trade models suggest surprisingly small gains from trade our model implies that introducing channels through a sovereign bond market greatly magnifies the gains from trade key mechanisms in the model are confirmed by data and the results are found to be robust to a variety of considerations

learning uncertainty and central bank activism in an economy with strategic interactions abstract in this paper we examine the optimal level of central bank activism in a standard model of monetary policy with uncertainty learning and strategic interactions we calibrate the model using g7 data and find that the presence of strategic interactions between the central bank and private agents creates an additional motivation for caution in the optimal monetary policy an activist policy designed to help learning and reduce future uncertainty creates extra volatility in inflation expectations which is detrimental to welfare

social networks neighborhood effects and credit access evidence from rural guatemala we measure the extent to which social networks determine sources of credit from a survey of 465 households in western guatemala we estimate correlated contextual and endogenous effects of networks at the neighborhood church and village levels finding that church networks display endogenous effects in credit access we calculate an elasticity of social imitation esi indicating if the percentage of people accessing microfinance in a church network doubles the probability of an individual household accessing microfinance increases by 14 1 percent a magnitude similar to our estimated esis for televisions and cell phones within church and neighbor networks

output spillovers from changes in sovereign credit ratings this research examines how a sovereign rating revision of one country influences the economic growth rates of other countries rating revisions have significant output spillover effects a one notch upgrade downgrade prompts on average a significant downward revision of about 0 03 0 07 in the consensus forecast of annual economic growth rates of other countries in the two month period after the event the spillovers are transmitted through direct and indirect trade and financial linkages between event and non event countries the evidence indicates that a predominance of differential common spillovers leads upgrades downgrades to produce adverse output effects for other countries

sovereign credit spreads under good bad governance abstract this paper explores how sovereign credit spreads vary with the level of governance an analysis of 74 countries over the 2001 2016 period shows that sovereign credit default swap cds spreads decrease with government effectiveness particularly in countries exhibiting severe default risk high indebtedness and poor economic conditions we formulate a theoretical explanation for these findings using a structural model in which governments adjust default and debt policies based on their abilities to collect and use fiscal revenues the theory posits that more effective governments have less incentive to default and thus benefit from narrower credit spreads although they may choose higher indebtedness levels

a systematic framework for analyzing the dynamic effects of permanent and transitory shocks this paper proposes a systematic framework for analyzing the dynamic e ects of permanent and transitory shocks on a system of n economic variables we consider a two step orthogonolization on the residuals of a vecm with r cointegrating vectors the rst step separates the permanent from the transitory shocks and the second step isolates n r mutually uncorrelated permanent shocks and r transitory shocks the decomposition is computationally straightforward and entails only a minor modi cation to the choleski decomposition commonly used in the literature we then show how impulse response functions can be constructed to trace out the propagating mechanism of shocks distinguished by their degree of persistence in an empirical example the dynamic responses to the identi ed permanent shocks have properties similar to shocks to productivity the real interest rate and money growth even though no economic

strategic models of sovereign debt renegotiations the sovereign debt literature has often implicitly assumed that all the power in the bargaining game between debtor and creditor lies with the latter this paper explores that assumption by analyzing three game theoretic models of debt renegotiations in two of the models both of which are built on the traditional one sector growth model all the subgame perfect equilibria have an extreme form in which the game s surplus is captured by the creditor the third game has many subgame perfect equilibria that do not have this feature however the roles of various assumptions in all three games are examined

risk matching behavior in microcredit group formation evidence from northern ethiopia theoretical models on group lending assume the formation of groups of homogenous risk types recent theoretical and empirical findings challenge this view arguing that when markets for insurance are missing risk homogeneity may not hold any more and risk heterogeneity can be the optimal outcome using data from an mfi in tigray ethiopia this article examines the homogeneity hypothesis and reflects on implications for repayment no evidence is found that supports risk homogeneity even accounting for matching frictions however we also do not find an explicit link between the presence of risk heterogeneity and side payments due to missing insurance as suggested in the literature instead other trust based social networks seem to underlie heterogeneity such social networks are often synchronized with credit groups and influence the probability of repayment under heterogeneity the implication is that successful repayment rates in group lending need not arise only under risk homogeneity but can also arise under risk heterogeneity heterogeneity may also serve to bridge missing insurance markets in poor rural environments mfis therefore need to consider such local conditions when designing their lending schemes

sovereign risk and secondary markets conventional wisdom says that in the absence of default penalties sovereign risk destroys all foreign asset trade we show that this conventional wisdom rests on one implicit assumption that assets cannot be retraded in secondary markets without this assumption foreign asset trade is possible even in the absence of default penalties this result suggests a broader perspective regarding the origins of sovereign risk and its remedies sovereign risk affects foreign asset trade only if default penalties are insufficient and secondary markets work imperfectly to reduce its effects one can either increase default penalties or improve the working of secondary markets jel f34 g12 g15

political connections and social networks in targeted transfer programs evidence from rural ethiopia abstractdespite increasingly large scale social protection programs in africa we have limited evidence on the local political economy of their allocation we investigate community based processes for food aid allocation and the role of political and social networks using the case of ethiopia in the aftermath of a serious drought in 2002 local political authorities are in charge of food transfers in terms of free food aid or food for work programs we find that although targeting is clearly imperfect free food aid is responsive to need as well as targeted to households with less access to support from relatives or friends we also find a strong correlation with political connections households with close associates in official positions have more than a 12 higher probability of obtaining free food than households that are not well connected this effect is large someone without political connections has the same probability of getting food aid as someone more than twice as rich but with these conne

the costs of sovereign default theory and empirical evidence economic policymakers sometimes perceive a sovereign default as a jump into the unkown the main piece of information missing is what the costs of the default are going to be assessing these costs correctly is crucial for evaluating how far a country should go to avoid a default this paper analyzes the main sources of the costs of default discussed in the theoretical literature and evaluates the empirical evidence on the matter i classify these potential sources in three groups 1 sanctions imposed as penalties by creditors 2 costs related to the information content of default and 3 costs related to domestic agents sovereign bond holdings i then present a simple model that captures the main intuition behind each of them a review of the empirical evidence suggests that while the costs generated in the aftermath of defaults by traditional mechanisms such as trade sanctions or exclusion from credit markets have not been significant in recent decades costs deriving from information revelation and the impact on domestic bondholders particularly the banking system have become major consequences of sovereign defaults

the meaning of kinship in sharecropping contracts analysis of a household survey from the philippines shows that the behavior of sharecroppers with a kinship relation with their landlord is not affected by the disincentive effects of product and factor sharing while behavior of the other sharecroppers responds to the contract terms we characterize the meaning of kinship ties through a survey of opinion conducted among tenants the survey shows that kin landlords help or are expected to help more frequently in case of emergency than other landlords and they do so with a wider range of instruments providing the incentive for cooperative behavior in sharecropping contracts among kin

making the most of high inflation this article examines the relationship between the real effects of inflation and its level in countries with frequent episodes of high inflation the real effects are computed as asymmetric impulse responses of output to inflation separately in the regimes with different signs of the differences between the expected inflation and the predicted output neutral inflation it is found that with the increase in inflation such effects increase in the regime with the positive sign relatively to the effects in the regime with the negative sign it is also shown that this finding is valid for most countries with high inflation episodes where inflation is greater than 4 8 for at least 25 of quarterly observations this leads to a simple policy prescription that in economies with frequent high inflation episodes anti inflationary monetary decisions are least damaging for output if undertaken in the periods when the difference between the expected and output neutral inflation is negative

interactions between institutional and informal credit agencies in rural india in an attempt to expand rural credit and displace the village moneylender india created a system of rural cooperatives in the 1950s and expanded branch banking into rural areas in the 1970s this article examines how these measures affected the rural market it begins with the question of how large the expansion of institutional credit has been and the extent to which it has dislodged the village and nonresident moneylenders a detailed comparison of three major surveys of the indian rural credit market suggests that in various guises the moneylender is still a major source of loans the article also examines the weak evidence on intermediation between the formal and informal sectors a formal model of the interaction between the informal moneylender and institutional lender is constructed under a variety of assumptions about the exclusivity of loan contracts and the competitive structure of the informal sector the conclusions are drawn together in the form of five proposals for public policy

inflation and monetary dynamics in the us a quantity theory approach in this article we investigate the long run link between inflation and money growth in the united states since 1960 a measure of the long run inflation trend is constructed which bears the interpreation of monetary inflation rate and is directly related to the excess nominal money growth process money growth less output growth as postulated by the quantity theory consistent with the memory characteristics of the series their fractional integration and cointegration properties are taken into account in empirical modelling the proposed measure is then compared with several existing measures of core inflation aimed at capturing long run inflation dynamics but unrelated to money growth the monetary long run inflation rate performs well in out of sample forecasting exercises especially over a 2 3 year horizon yielding valuable information to monetary policymakers

consumption risk technology adoption and poverty traps evidence from ethiopia much has been written on the determinants of input and technology adoption in agriculture with issues such as input availability knowledge and education risk preferences profitability and credit constraints receiving much attention this paper focuses on a factor that has been less well documented the differential ability of households to take on risky production technologies for fear of the welfare consequences if shocks result in poor harvests building on an explicit model this is explored in panel data for ethiopia historical rainfall distributions are used to identify the counterfactual consumption risk controlling for unobserved household and time varying village characteristics it emerges that not just ex ante credit constraints but also the possibly low consumption outcomes when harvests fail discourage the application of fertilizer the lack of insurance causes inefficiency in production choices
