the impact of uncertainty shocks in emerging economies abstract a recent strand of research proposes that sudden jumps in uncertainty generate rapid drops and recoveries in real macroeconomic variables that drive the business cycle using an empirical model we find substantial heterogeneity in reactions to these shocks across countries in comparison to the u s and other developed countries emerging economies suffer much more severe falls in investment and private consumption following an exogenous uncertainty shock take significantly longer to recover and do not experience a subsequent overshoot in activity we provide evidence that the dynamics of investment and consumption are correlated with the depth of financial markets we control for the potential role of a credit channel and estimate that it can account for up to one half of the increased fall in investment generated by uncertainty shocks among emerging economies with less developed financial markets in this context monetary and fiscal policy actions that alleviate the impact of credit constraints facing firms may reduce the impact of uncertainty shocks in these economies

catalytic finance when does it work in a model of debt crisis caused partly by creditor coordination failure we show that bailouts that reduce ex post inefficiency will sometimes enhance the incentives for governments to take costly adjustment effort this model helps us understand a debate about the role of the imf in catalyzing lending to developing countries

bilateral trading with naive traders we introduce naive traders in bilateral trading these traders report their true types in direct mechanisms and bid ask their values costs in auctions we show that by expropriating naive traders in direct mechanisms the mechanism designer can subsidize additional trades by strategic traders and improve efficiency in fact complete expropriation of naive traders is a necessary condition for constrained efficiency a significant implication is that in the presence of naive traders ex post individually rational mechanisms are not constrained efficient in contrast if the traders must use a given mechanism then the introduction of naive traders has an ambiguous effect on efficiency

on the sources of aggregate fluctuations in emerging economies recent research on macroeconomic fluctuations in emerging economies has advocated introducing a stochastic productivity trend or allowing for interest rate shocks and financial frictions we estimate a model that encompasses these two approaches shedding light on their relative merits and on how financial frictions affect the transmission of shocks the model accounts for aggregate fluctuations by assigning a dominant role to financial frictions in amplifying conventional temporary productivity shocks whereas trend shocks play a minor role a link between spreads and expected future productivity emerges as essential for a reasonable approximation to the data

what can we learn about financial access from u s immigrants the role of country of origin institutions and immigrant beliefs immigrants from countries with more effective institutions are more likely than other immigrants to have a relationship with a bank and to use formal financial markets more extensively the evidence that a country s institutional environment shapes beliefs and by extension the use of financial services provides support for policies that focus on institutional reforms in promoting financial access after holding wealth education and other factors constant the impact of institutional quality in the country of origin affects the financial market participation of all immigrant groups except those who have lived in the united states for more than 28 years these findings are robust to alternative measures of institutional effectiveness to controlling for additional country of origin characteristics and to various methods for addressing potential biases caused by immigrant self selection

individual risk attitudes measurement determinants and behavioral consequences this paper studies risk attitudes using a large representative survey and a complementary experiment conducted with a representative subject pool in subjects homes using a question asking people about their willingness to take risks in general we find that gender age height and parental background have an economically significant impact on willingness to take risks the experiment confirms the behavioral validity of this measure using paid lottery choices turning to other questions about risk attitudes in specific contexts we find similar results on the determinants of risk attitudes and also shed light on the deeper question of stability of risk attitudes across contexts we conduct a horse race of the ability of different measures to explain risky behaviors such as holdings stocks occupational choice and smoking the question about risk taking in general generates the best all round predictor of risky behavior

debt maturity and the international financial architecture this paper presents a theory of the maturity of international sovereign debt and derives its implications for the reform of the international financial architecture the analysis is based on a model in which the need to roll over external debt disciplines the policies of debtor countries but makes them vulnerable to unwarranted debt crises due to bad shocks the paper presents a welfare analysis of several measures that have been discussed in recent debates such as international lending in last resort or the establishment of a mechanism for suspending payments on the external debt of crisis countries jel f34 o19

sovereign debt as a contingent claim a quantitative approach abstract we construct a dynamic equilibrium model with contingent service and adverse selection to quantitatively study sovereign debt in the model benefits of defaulting are tempered by higher future interest rates for a wide set of parameters the only equilibrium is one in which the sovereign defaults in all states additional output losses however sustain equilibria that resemble the data we show that due to the adverse selection problem some countries choose to delay default to reduce loss of reputation moreover although equilibria with no default imply greater welfare levels they are not sustainable in highly indebted and volatile countries

the imf a bird s eye view of its role and operations the international monetary fund imf is the world s premier international financial institution with 184 member countries and active programmes in a significant number of them at any one time the fund attracts a great deal of attention much of it critical but the discussion is often polemic in style strongly held but frequently opposing views are expressed this survey attempts to examine in an objective way the theory and evidence relating to the fund s operations many aspects of the empirical research are relatively recent and a universal consensus is yet to emerge as a consequence there is scope for disagreement to persist however the research is also gradually clarifying many important issues the format for the survey is to examine the life cycle of imf arrangements what makes a country turn to the fund for assistance should the imf be lending what influences the outcome of negotiations and the design of programmes are imf programmes effective and why do some countries make prolonged use of imf resources for completeness there is also some discussion of the history of the imf the extent to which fund policies have been influenced by advances in economic theory and the fund s systemic role important organisational and governance issues are also covered briefly although primarily adopting an economist s perspective the survey reflects the growing recognition that in order to understand the imf s operations economics has to be combined with politics examining the imf is an exercise in applied political economy copyright 2007 the author journal compilation 2007 blackwell publishing ltd

debt maturity without commitment i analyze how lack of commitment afiects the maturity structure of sovereign debt governments balance beneflts of default induced redistribution and costs due to income losses in the wake of a default their choice of short versus longterm debt afiects default and rollover decisions by subsequent policy makers the equilibrium maturity structure is shaped by revenue losses on inframarginal units of debt that re ect the price impact of these decisions the model predicts an interior maturity structure with positive gross positions and a shortening of the maturity structure when debt issuance is high output low or a cross default more likely these predictions are consistent with empirical evidence

a quantitative model of sovereign debt bailouts and conditionality in times of sovereign debt crises international financial institutions provide temporary financial support contingent on the implementation of specific macroeconomic policies this paper develops a model of sovereign debt and default with endogenous participation rates in bailout programs conditionality enters as a constraint on fiscal policy in the model the insurance character of bailouts generates incentives for debt accumulation quantitative results suggest that bailouts prevent sovereign defaults in the short run but may come at a cost of a greater default probability in the long run increasing the intensity of conditionality lowers the bailout participation rate and generates a hump shaped pattern of sovereign default risk

on optimal public good provision with tax evasion it is proved that for public goods with zero income effects also called ziff public goods tax evasion does not affect the optimal level of public expenditure further examples show that in general tax evasion may lead to less but also to more public expenditure

representative evidence on lying costs abstract a central assumption in economics is that people misreport their private information if this is to their material benefit several recent models depart from this assumption and posit that some people do not lie or at least do not lie maximally these models invoke many different underlying motives including intrinsic lying costs altruism efficiency concerns or conditional cooperation to provide an empirically validated microfoundation for these models it is crucial to understand the relevance of the different potential motives we measure the extent of lying costs among a representative sample of the german population by calling them at home in our setup participants have a clear monetary incentive to misreport misreporting cannot be detected reputational concerns are negligible and altruism efficiency concerns or conditional cooperation cannot play a role yet we find that aggregate reporting behavior is close to the expected truthful distribution suggesting that lying costs are large and widespread further lab experiments show that this result is not driven by the mode of communication

sovereign debt structural adjustment and conditionality abstract the lack of a proper enforcement mechanism for sovereign debt generates a commitment failure as a result a sovereign may seek to improve its position in debt renegotiations and thus evade its debt obligations by reducing exports conditionality seeks to provide a solution to the incentive problem by addressing the commitment failure formalizing this argument we show that conditionality helps the repayment of sovereign debt in certain circumstances it can eliminate debt overhang especially when it is coupled with concessionary lending of sufficient magnitude it is however unable to restore first best when it is anticipated by lenders conditionality may get international financial institutions and sovereign debtors into a trap where the debt overhang persist debt rescheduling takes place periodically and conditionality continues indefinitely

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

gender and competition at a young age gender gaps may be observed in a variety of economic and social environments one of the possible determining factors is that men are more competitive than women and so when the competitiveness of the environment increases the performance of men increases relative to that of women we test this hypothesis in a field study conducted with 9 year old children running on a track they first run alone and then in pairs over a short distance with different gender composition of the pairs the results support the hypothesis that performance in competition varies according to gender when children ran alone there was no difference in performance in competition boys but not girls improved their performance this finding relates to the discussion regarding single sex schools the outcomes of examinations in a mixed sex school can show a gender gap in favor of boys even when this gap does not reflect actual abilities girls who are as talented as boys will end up performing worse just because they are not as competitive and will not achieve as high scores in examinations as boys

external shocks u s monetary policy and macroeconomic fluctuations in emerging markets estimated structural vars show that external shocks are an important source of macroeconomic fluctuations in emerging markets furthermore u s monetary policy shocks affect interest rates and the exchange rate in a typical emerging market quickly and strongly the price level and real output in a typical emerging market respond to u s monetary policy shocks by more than the price level and real output in the u s itself these findings are consistent with the idea that when the u s sneezes emerging markets catch a cold at the same time u s monetary policy shocks are not important for emerging markets relative to other kinds of external shocks

inherited trust and growth this paper develops a new method to uncover the causal effect of trust on economic growth by focusing on the inherited component of trust and its time variation we show that inherited trust of descendants of us immigrants is sig nificantly influenced by the country of origin and the timing of arrival of their forebears we thus use the inherited trust of descendants of us immigrants as a time varying measure of inherited trust in their country of origin this strategy allows to identify the sizeable causal impact of inherited trust on worldwide growth during the twentieth century by controlling for country fixed effects jel n11 n12 n31 n32 o47 z13

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

sovereign defaults and liquidity crises abstract sovereign debt crises in emerging markets are usually associated with liquidity and banking crises the conventional view is that the domestic turmoil is the consequence of foreign retaliation although there is no clear empirical evidence on classic default penalties this paper emphasizes instead a direct link between sovereign defaults and liquidity crises building on two natural assumptions i government bonds represent a source of liquidity for the domestic private sector and ii the government cannot discriminate between domestic and foreign creditors in the event of default in this context external debt emerges even in the absence of classic penalties and government default is countercyclical triggers a liquidity crunch and amplifies output volatility in addition a reform that involves a substitution of government bonds with privately sourced liquidity instruments could backfire by restricting governments access to foreign credit

contracting for health services when patient demand does not reflect quality this paper analyses contracts to keep down costs while maintaining quality of health services when patient demand does not reflect quality there is then a natural role for forms of contract that have emerged during the reforms of the nhs in britain that differ from pure fixed price or cost reimbursement contracts the optimal form depends on whether the provider is entirely self interested or benevolent in having genuine concern for patient welfare with fully benevolent providers there are roles for block and cost and volume contracts with partially benevolent providers some degree of cost sharing is typically optimal

honesty in a model of strategic information transmission we consider the following simple model of consumer fraud consumers need one of two possible repairs an expensive repair denoted e or an inexpensive repair denoted i the exogenous probability that a consumer needs the more costly remedy is r each consumer is assumed to know r an expert can observe with certainty which of the two repairs is needed and can offer to sell either to the consumer in a simple extension we allow for uncertainty with respect to the expert s observation we assume that selling the expensive remedy to a consumer who needs only the inexpensive one is more profitable than selling the inexpensive one thus h eii h1 iji where h denotes profit and i denotes conditional on needing the profit functions are increasing in the price of the respective repairs for convenience we suppress the dependence of h on prices in our notation we also assume that a consumer prefers to obtain the appropriate repair to the inappropriate one thus u eie u ije and u iii u eii where u is the consumer s payoff lastly we assume that the functions u eje and u e i are decreasing in the price of the expensive repair and that u iie and u iii are decreasing in the price of the inexpensive repair we also assume that u iie is decreasing in the price of the expensive repair since the consumer ultimately buys the expensive repair in this case see below for further assumptions regarding the repairs we are interested in the equilibrium levels of honesty in this model how honest is the expert at the equilibrium do consumers always follow the expert s advice does the level of honesty increase as the interests of the agents become more similar in a sense to be defined below our assumptions are similar to those in the abstract strategic information transmission models of vincent crawford and joel sobel 1982 and jerry green and nancy stokey 1980 we follow the former paper which asks whether the signals sent become less noisy as the agents preferences become more similar despite the similarity of our model to crawford sobel s we arrive at some different conclusions with respect to the expert s honesty vis a vis the agents closeness of interests we explain this in detail in section iii in addition we allow that the expert may be uncertain about the true state of the world we also explicitly model the level of expert honesty which extends crawford sobel the outline of the paper is as follows in section i we provide the details of the model and show that a unique equilibrium exists comparative static results and a simple extension incorporating the assumption of the incompetent expert are given in section ii we draw comparisons with crawfordsobel in section iii in section iv we conclude with a brief summary

is there a cultural component in tax morale evidence from immigrants in europe abstract in this paper we examine the existence of a cultural component in individual tax morale to identify the effect of culture we use immigrant data drawn from the european social survey we find that culture is a significant determinant of tax morale the level of tax morale in the country of immigrant origin influences individual tax morale in the destination country the result is robust to the inclusion of a wide set of individual and aggregate controls and persists across different population segments

understanding the costs of sovereign default american state debts in the 1840 s the defaults of u s states in the 1840s provide a powerful test of competing models of sovereign debt the eleventh amendment to the u s constitution prevented foreign creditors from obtaining payment in the federal courts moreover because the defaulting states were part of a large and economically integrated nation creditors could not enforce payment by imposing military or trade sanctions in spite of the lack of sanctions however most states eventually repaid in full it appears that the states repaid in order to maintain access to capital markets much as in reputational models of sovereign debt copyright 1996 by american economic association

measuring lying aversion abstract we introduce a new method for measuring the decision to lie in experiments in the game the decision to lie increases own payment independent of the counterpart s decision but potentially at a cost for the counterpart we identify at the individual level the decision to lie and measure how individuals react to different incentives to lie furthermore we investigate how lying behavior changes over time our method allows us to classify people into types including those who never lie those who always lie and those who react to incentives to lie we suggest this method as a useful instrument for examining factors that influence the decision to lie

motivation money prestige and cheats a b s t r a c t this paper investigates the effects of supervision and incentives on subjects performance and cheating behavior in a real effort task with a sample of 540 participants in three differ ent experiments we investigated the interaction between motivation and monetary and social rewards with and without supervision our results suggest 1 lack of supervision promotes cheating though workers tend to cheat moderately 2 both economic and social incentives increase motivation but only when workers like their jobs 3 workers do not increase their band of acceptable dishonest behavior for possible economic rewards but they do increase dishonest behavior for possible social rewards like prestige

loss aversion and lying behavior abstract we theoretically show that loss averse agents are more likely to lie to avoid receiving a low payoff after a random draw the lower the ex ante probability of this bad outcome the ex ante expected payoff increases as the bad outcome becomes less likely and hence the greater is the loss avoided by lying we demonstrate robust support for this theory by reanalyzing the results from the extant literature and with a new experiment that varies the outcome probabilities and is run double anonymous

monitoring motivation and management the determinants of opportunistic behavior in a field experiment economic models of incentives in employment relationships are based on a specific theory of motivation employees are rational cheaters who anticipate the consequences of their actions and shirk when the marginal benefits exceed costs we investigate the rational cheater model by observing how experimentally induced variation in monitoring of telephone call center employees influences opportunism a significant fraction of employees behave as the rational cheater model predicts a substantial proportion of employees however do not respond to manipulations in the monitoring rate this heterogeneity is related to variation in employee assessments of their general treatment by the employer jel d2 j2 l2 l8 m12

honesty and evasion in the tax compliance game conventional models of tax compliance emphasize that taxpayers make strategic tax reports underreporting income to the extent that this behavior is functionally rewarded in contrast to this view considerable empirical evidence suggests that many taxpayers are inherently honest reporting truthfully regardless of the incentive to cheat in this article we build a game theoretic model of tax compliance that includes both honest and potentially dishonest taxpayers we show that including honest taxpayers significantly alters the model leading to much improved empirical predictions and somewhat different and novel policy implications

macroprudential policy in the presence of external risks abstract we document the relevance of external risks shocks to the level and volatility of world interest rates in shaping economic activity in emerging market economies emes and characterize optimal macroprudential policy in response to these risks in a small open economy subject to financial crises low and stable interest rates reinforce overborrowing arising from a pecuniary externality generated by collateral constraints that depend on asset prices we show that this mechanism leads to greater exposure to crises typically accompanied by abrupt increases in interest rates and a persistent rise in their volatility as observed during sudden stops in emes a tax on international borrowing that implements a social planner s optimal policy can be decomposed into three factors the severity of future crises the ability of the planner to dampen future crises and the incidence of future crises we show that the effects of interest rate volatility on these factors implies that qualitatively the tax responds non monotonically with respect to the direction of volatility shocks and that quantitatively increasing macroprudential taxes is seldom the optimal response to an increase in interest rate volatility

regime switches agents beliefs and post world war ii u s macroeconomic dynamics the evolution of inflation and output over the last 50 years is examined through the lens of a micro founded model that allows for changes in the behavior of the federal reserve and in the volatility of structural shocks agents are aware of the possibility of regime changes and their beliefs have an impact on the law of motion underlying the macroeconomy the results support the view that there were regime switches in the conduct of monetary policy however the behavior of the federal reserve is identified by repeated fluctuations between a hawk and a dove regime instead of by the traditional pre and post volcker structure counterfactual simulations show that if agents had anticipated the appointment of an extremely conservative chairman inflation would not have reached the peaks of the late 70s and the inflation output trade off would have been less severe these beliefs counterfactuals are new in the literature finally the paper provides a bayesian algorithm to handle the technical difficulties that arise in a rational expectations model with markov switching regimes

optimal time consistent macroprudential policy collateral constraints widely used in models of financial crises feature a pecuniary externality agents do not internalize how borrowing decisions made in good times affect collateral prices during a crisis we show that under commitment the optimal financial regulator s plans are time inconsistent and study time consistent policy quantitatively this policy reduces sharply the frequency and magnitude of crises removes fat tails from the distribution of asset returns and increases social welfare in contrast constant debt taxes are ineffective and can be welfare reducing while an optimized macroprudential taylor rule is effective but less so than the optimal time consistent policy

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

cheating ourselves the economics of tax evasion no government can announce a tax system and then rely on taxpayers sense of duty to remit what is owed some dutiful people will undoubtedly pay what they owe but many others will not over time the ranks of the dutiful will shrink as they see how they are being taken advantage of by the others thus paying taxes must be made a legal responsibility of citizens with penalties attendant on noncompliance but even in the face of those penalties substantial tax evasion exists and always has the history of taxation is replete with episodes of evasion often notable for their inventiveness during the third century many wealthy romans buried their jewelry or stocks of gold coin to evade the luxury tax and homeowners in eighteenth century england temporarily bricked up their fireplaces to escape notice of the hearth tax collector webber and wildavsky 1986 p 141 this essay reviews what is known about the magnitude nature and determinants of tax evasion with an emphasis on the u s income tax alm 1999 andreoni erard and feinstein 1998 and slemrod and yitzhaki 2002 offer more comprehensive recent reviews of the literature it then places this information into a conceptual and policy context

context dependent cheating experimental evidence from 16 countries policy makers use several international indices that characterize countries according to the quality of their institutions however no effort has been made to study how the honesty of citizens varies across countries this paper explores the honesty among citizens across 16 countries with 1440 participants we employ a very simple task where participants face a trade off between the joy of eating a fine chocolate and the disutility of having a threatened self concept because of lying despite the incentives to cheat we find that individuals are mostly honest further international indices that are indicative of institutional honesty are completely uncorrelated with citizens honesty for our sample countries

fluctuations in uncertainty this review article tries to answer four questions i what are the stylized facts about uncertainty over time ii why does uncertainty vary iii do fluctuations in uncertainty matter and iv did higher uncertainty worsen the great recession of 2007 2009 on the first question both macro and micro uncertainty appears to rise sharply in recessions on the second question the types of exogenous shocks like wars financial panics and oil price jumps that cause recessions appear to directly increase uncertainty and uncertainty also appears to endogenously rise further during recessions on the third question the evidence suggests uncertainty is damaging for short run investment and hiring but there is some evidence it may stimulate longer run innovation finally in terms of the great recession the large jump in uncertainty in 2008 potentially accounted for about one third of the drop in gdp

regime switching in emerging market business cycles interest rate volatility and sudden stops abstract we document the presence of discrete regime switching in emerging market business cycles particularly in the volatility of interest rates at which countries borrow internationally using a multi country regime switching vector autoregressive model we study the statistical relationship of such business cycle regimes with episodes of sudden stops periods of high volatility tend to be persistent and are associated with high interest rates the occurrence of sudden stops in external financing and large declines in economic activity most strikingly we show that regime switches drive the countercyclicality of interest rates in emerging markets documented in previous literature neumeyer and perri 2005 and that high volatility regimes forecast sudden stops 6 and 12 months ahead

what determines corruption international evidence from microdata this paper uses a microlevel data set from 49 countries to create a direct measure of corruption which portrays the extent of bribery as revealed by individuals who live in those countries in addition it investigates the determinants of being asked for a bribe at the individual level the results show that both personal and country characteristics determine the risk of exposure to bribery examples are gender income education marital status the city size the country s unemployment rate average education and the strength of the institutions in the country jel k4 d73 p16

optimal maturity of nominal government debt an infinite horizon model the role of debt maturity is analyzed in a framework that blends tax smoothing with time inconsistency of optimal policy when policymakers have an incentive to use unanticipated inflation to reduce the real value of nominal government liabilities three conclusions emerge 1 nominal debt leads policymakers to resort to inflation even though in equilibrium inflation collects no revenue 2 when under full precommitment the optimal policy calls for complete tax smoothing and a constant debt level the equilibrium policy without precommitment calls for anticipating tax collection and early debt repayment and 3 management of debt maturity is an essential component of the equilibrium policy copyright 1992 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

coordination failures and the lender of last resort was bagehot right after all the classical doctrine of the lender of last resort lolr elaborated by bagehot 1873 asserts that the central bank should lend to illiquid but solvent banks under certain conditions several authors have argued that this view is now obsolete in modern interbank markets a solvent bank cannot be illiquid this paper provides a possible theoretical foundation for rescuing bagehot s view our theory does not rely on the multiplicity of equilibria that arises in classical models of bank runs we built a model of banks liquidity crises that possesses a unique bayesian equilibrium in this equilibrium there is a positive probability that a solvent bank cannot find liquidity assistance in the market we derive policy implications about banking regulation solvency and liquidity ratios and interventions of the lender of last resort furthermore we find that public bailout and private bail in involvement are complementary in implementing the incentive efficient solution and that bagehot s lender of last resort facility must work together with institutions providing prompt corrective action and orderly failure resolution finally we derive similar implications for an international lender of last resort ilolr jel g21 g28

why do emerging economies borrow short term the authors argue that emerging economies borrow short term due to the high risk premium charged by international capital markets on long term debt they first present a model where the debt maturity structure is the outcome of a risk sharing problem between the government and bondholders by issuing long term debt the government lowers the probability of a liquidity crisis transferring risk to bondholders in equilibrium this risk is reflected in a higher risk premium and borrowing cost therefore the government faces a tradeoff between safer long term borrowing and cheaper short term debt second the authors construct a new database of sovereign bond prices and issuance they show that emerging economies pay a positive term premium a higher risk premium on long term bonds than on short term bonds during crises the term premium increases with issuance shifting toward shorter maturities this suggests that changes in bondholders risk aversion are important to understand emerging market crises

the debt burden and debt maturity at low and moderate levels of government debt there appears to be little relation between the level of debt and its maturity but at high levels of debt a strong inverse relation emerges we start the paper by documenting this inverse relation for those oecd countries which have reached very high levels of debt we then provide a theory of the joint movements of debt and maturity which can explain both sets of facts it is based on the idea that at high levels of debt the government may need to decrease the maturity of the debt as debt increases in order to maintain the credibility of its anti inflation stance this abstract was borrowed from another version of this item

why do we lie a practical guide to the dishonesty literature over the last decade a massive body of research has been devoted to uncovering human dishonesty in the present paper we review more than a hundred papers from this literature and provide a comprehensive overview by first listing the existing theoretical frameworks and then covering the common empirical approaches synthesizing the demographic and personal characteristics of those who cheat identifying the behavioural mechanisms found that affect dishonesty and finally we finish by discussing how the empirical evidence fit theory overall the review concludes that many people behave dishonestly but also that it is a highly malleable behavior sensitive to elements such as decision contexts behaviour of others state of mind and depletion the review can be used as an overview of the dishonesty literature or as a guide or work of reference for selected topics of interest

man s search for meaning the case of legos we investigate how perceived meaning influences labor supply in a laboratory setting we manipulate the perceived meaning of simple repetitive tasks and find a strong influence on subjects labor supply despite the fact that the wage and the task are identical across the conditions in each experiment subjects in the less meaningful conditions exhibit reservation wages that are consistently much higher than the subjects in the more meaningful conditions the result replicates across different types of tasks moreover in the more meaningful conditions subjects productivity influences labor supply more strongly

income inequality and sovereign default abstract in this paper we study how income inequality matters for government borrowing and default decisions we extend a standard endogenous sovereign debt default model to allow for heterogeneous agents and stochastic variability in the dispersion of income we calibrate the model to match a number of stylized facts for argentina we show that i rising income inequality within a country increases the probability of default significantly ii the effect of output shocks is larger than the effect of inequality shocks iii the joint effect of these two shocks can generate a high default probability consistent with the argentine data iv the model can match the high volatility of consumption by the poor relative to the rich and v more progressive income taxes lead to lower default risk

haircuts estimating investor losses in sovereign debt restructurings 1998 2005 abstract we calculate investor losses haircuts and recovery values in recent debt restructurings in russia ukraine pakistan ecuador argentina and uruguay haircuts are computed as the percentage difference between the present values of old and new instruments discounted at the yield prevailing immediately after the exchange recovery value means value received in terms of outstanding principal we find average npv haircuts ranging from 13 uruguay external exchange to 73 2005 argentina exchange recovery values range from 30 to about 75 we also find within exchange variations in haircuts and recovery values depending on the bond tendered with a few exceptions domestic residents do not appear to have been treated systematically better or worse than foreign residents

strategic communication with lying costs i study a model of strategic communication between an uninformed receiver and an informed but upwardly biased sender the sender bears a cost of lying or more broadly of misrepresenting his private information the main results show that inflated language naturally arises in this environment where the sender almost always claims to be of a higher type than he would with complete information regardless of the intensity of lying cost there is incomplete separation with some pooling on the highest messages the degree of language inflation and how much information is revealed depend upon the intensity of lying cost the analysis delivers a framework to span a class of cheap talk and verifiable disclosure games unifying the polar predictions they make under large conflicts of interest i use the model to discuss how the degree of manipulability of information can affect the trade off between delegation and communication copyright 2009 wiley blackwell

honesty beliefs about honesty and economic growth in 15 countries the honesty of people in an online panel from 15 countries was measured in two experiments reporting a coin flip with a reward for heads and an online quiz with the possibility of cheating there are large differences in honesty across countries average honesty is positively correlated with per capita gdp this is driven mostly by gdp differences arising before 1950 rather than by gdp growth since 1950 a country s average honesty correlates with the proportion of its population that is protestant these facts suggest a long run relationship between honesty and economic development the experiment also elicited participants expectations about different countries levels of honesty expectations were not correlated with reality instead they appear to be driven by cognitive biases including self projection

sovereign default interest rates and political uncertainty in emerging markets abstract a large body of the empirical literature shows that high turnover rates length of tenure of policymakers and the degree of conflict within a country affects sovereign spreads debt and default rates we help to rationalize such claims by including these political features in a dynamic stochastic small open economy model of sovereign debt and default in this way we offer a complementary approach to the econometric analyses in the literature consistent with the data the quantitative analysis shows that politically unstable and more polarized economies experience higher default rates and larger level and volatility of sovereign interest rate spreads

tax morale affects tax compliance evidence from surveys and an artefactual field experiment our working hypothesis is that cross cultural differences in tax compliance behavior have foundations in the institutions of tax administration and citizen assessment of the quality of governance tax compliance being a complex behavioral issue its investigation requires use of a variety of methods and data sources results from artefactual field experiments conducted in countries with substantially different political histories and records of governance quality demonstrate that observed differences in tax compliance levels persist over alternative levels of enforcement the experimental results are shown to be robust by replicating them for the same countries using survey response measures of tax compliance

a fairness approach to income tax evasion abstract the tax that a taxpayer wishes to evade is determined on the basis of his perception of the fairness of his fiscal treatment with respect to both governmental supply of public goods and the perceived behaviour of other taxpayers the coercive powers of the state and the taxpayer s attitude toward risk determine the extent to which this desired level is undertaken in practice this approach is able to produce implications for the relationship between public expenditure tax rates and tax evasion which are more consistent with empirical evidence than the results of the conventional portfolio choice approach
