local government spending and service delivery in indonesia the perverse effects of substantial fiscal resources abstractlocal government spending and service delivery in indonesia the perverse effects of substantial fiscal resources regional studies this study examines the impact of local government expenditure on service delivery in indonesia district spending positively influences education health and infrastructure service access but only up to a point after which the relationship becomes negative the quadratic spending effects disappear for districts managed by directly elected executives and those that perform well on their financial audits for these arguably less corrupt districts the impact of spending on services is positive across the entire range of expenditure the consistently beneficial impact of less corrupt district spending on service access is mitigated however by rising dependence on intergovernmental transfers

does competition for capital discipline governments decentralization globalization and public policy competition among countries or regions within them to attract mobile capital is often thought to discipline their governments motivating them to invest more in infrastructure reduce waste and corruption and spend less on non productive public goods the result should be convergence on business friendly policies we argue that this requires an assumption units start out very similar that is often unrealistic if units are heterogeneous in natural resources geographical location inherited human capital or infrastructure capital mobility often weakens discipline on the poorlyendowed units this may help explain disappointing results of liberalizing capital flows within russia and sub saharan africa jel f36 h73 h87

optimal redistribution and monitoring of labor supply this paper extends the mirrlees 1971 model of optimal non linear income taxation with a monitoring technology that allows the government to verify labor supply at a positive but non infinite cost we analyze the joint determination of the non linear monitoring and tax schedules and the conditions under which these can be implemented monitoring of labor supply reduces the distortions created by income taxation and raises optimal marginal tax rates possibly above 100 the optimal intensity of monitoring increases with the marginal tax rate and the labor supply elasticity our simulations demonstrate that monitoring strongly alleviates the trade off between equity and efficiency welfare gains of monitoring are around 2 8 of total output the optimal intensity of monitoring follows a u shaped pattern similar to that of optimal marginal tax rates our paper can explain why large welfare states optimally rely on work dependent tax credits active labor market policies benefit sanctions and work bonuses in welfare programs

a comparative study of inequality and corruption this article argues that income inequality increases the level of corruption through material and normative mechanisms the wealthy have both greater motivation and more opportunity to engage in corruption whereas the poor are more vulnerable to extortion and less able to monitor and hold the rich and powerful accountable as inequality increases inequality also adversely affects social norms about corruption and people s beliefs about the legitimacy of rules and institutions thereby making it easier for them to tolerate corruption as acceptable behavior this comparative analysis of 129 countries using two stage least squares methods with a variety of instrumental variables supports the authors hypotheses using different measures of corruption the world bank s control of corruption index and the transparency international s corruption perceptions index the explanatory power of inequality is at least as important as conventionally accepted causes of corruption such as economic development the autho

real convergence empirical evidence for latin america this article investigates the real convergence of 17 latin american countries to the us economy for the period 1950 to 2011 time series methods are used to test stochastic and convergence these methods include the possibility of one or two structural changes the results show that when endogenous structural changes are considered several latin american countries exhibit stochastic convergence nevertheless real convergence to the us is found only for three latin american countries chile costa rica and trinidad and tobago with these countries also presenting evidence of stochastic and convergence

state corroding federalism competition among local governments in a decentralized political system is often thought to discipline lazy or corrupt officials improving public good provision and increasing welfare some scholars note possible distortions due to spillovers or a race to the bottom but suggest that central transfers or regulations can remedy these both arguments take for granted a framework of constitutional order in which the central government can collect taxes allocate transfers and enforce regulations autonomously but what if it can t we show that if central enforcement capacity is endogenous interjurisdictional competition may itself erode the center s ability to channel competition in welfare enhancing directions regional governments may compete for capital by shielding firms from central tax collectors bankruptcy courts or regulators the equilibrium result is weaker central law enforcement and usually lower welfare interjurisdictional competition corrodes the state we illustrate with three examples from russia china and the us of cases in which such competition apparently encouraged subnational politicians to help firms evade central taxes or regulations

inflation targeting an indirect approach to assess the direct impact it is quite difficult to assess the benefits of inflation targeting it since its immediate effect will be on inflation expectations an unobserved variable due to lack of comprehensive data on inflation expectations most studies so far concentrated on the impact of it either on observable variables like output unemployment and inflation or compared post it surveys of itcountries with nonit countries in our study we focus on a yet unanswered question i e how the expectations change with the adoption of it we suggest that heterogeneous inflation expectations lead to long memory in actual inflation and it if successful should decrease this persistence by concentrating the public s expectations toward the announced target empirical results confirm our hypothesis with a reduction in inflation memory after the adoption of it in almost all eight developed countries in our sample

on the determinants of fiscal centralization theory and evidence abstract this paper presents a simple model that unifies most of the results of the literature on fiscal federalism the model describes an economy characterized by two levels of government one public good and a private good the predictions of the model are tested by using a new set of measures of fiscal centralization the main findings are that country size income per capita ethnic fractionalization and level of democracy are negatively correlated with the degree of fiscal centralization the model is tested using ols tobit and semi parametric estimators the paper also shows that the variables included in the regression are helpful in the prediction of changes in the level of centralization

federalism as a commitment to reserving market incentives the authors advance a new perspective in the study of federalism their approach views federalism as a governance solution of the state to credibly preserving market incentives market incentives are preserved if the state is credibly prevented from compromising on future economic success and from bailing out future failures the salient features of federalism decentralization of information and authority and interjurisdictional competition help provide credible commitment or these purposes in addition the authors suggest that some federalism are self sustaining

are output fluctuations transitory according to the conventional view of the business cycle fluctuations in output represent temporary deviations from trend the purpose of this paper is to question this conventional view if fluctuations in output are dominated by temporary deviations from the natural rate of output then an unexpected change in output today should not substantially change one s forecast of output in say five or ten years our examination of quarterly postwar united states data leads us to be skeptical about this implication the data suggest that an unexpected change in real gnp of 1 percent should change one s forecast by over 1 percent over a long horizon

the role of unemployment insurance in an economy with liquidity constraints and moral hazard the potential welfare benefits of unemployment insurance along with the optimal replacement ratio are studied using a quantitative dynamic general equilibrium model to provide a role for unemployment insurance agents in our economy face exogenous idiosyncratic employment shocks and are unable to borrow or insure themselves through private markets in the absence of moral hazard replacement ratios as high as 65 are optimal and the welfare benefits of unemployment insurance are quite large however if there is moral hazard and the replacement ratio is not set optimally but is instead set to an empirically plausible value the economy can be much worse off than it would be without unemployment insurance

fractional cointegration analysis of eu convergence traditional cointegration tests do not provide strong evidence of convergence between eu countries in this study fractional cointegration analysis is used to test for convergence between eu members fractional cointegration between inflation and between long term interest rates is found the results indicate that there is nominal convergence but that the equilibrium errors display long memory fractional cointegration analysis gives no evidence of real convergence in output

risk and return long run relations fractional cointegration and return predictability univariate dependencies in market volatility both objective and risk neutral are best described by long memory fractionally integrated processes meanwhile the ex post difference or the variance swap payoff reflecting the reward for bearing volatility risk displays far less persistent dynamics using intraday data for the standard poor s 500 and the volatility index vix coupled with frequency domain methods we separate the series into various components we find that the coherence between volatility and the volatilityrisk reward is the strongest at long run frequencies our results are consistent with generalized long run risk models and help explain why classical efforts of establishing a

threshold nonlinearities in output some international evidence the empirical adequacy of linear ar and nonlinear setar models of trend stationary and difference stationary representations of output for canada germany japan the uk and the us are appraised test results suggest the presence of linear model residual structure of some form for all series and nonlinearities of specifically threshold form in trend stationary data for canada germany japan and the us and difference stationary data for germany japan and the us with the exception of canada estimated threshold nonlinear models imply asymmetric dynamics are able to account for all nonlinear structure in the data on the basis of bds statistics and provide sizeable reductions in residual variance in several cases most notably for germany

consumption innovation persistence and the excess smoothness debate based on studies using us data consumption is too smooth relative to the implications of the rational expectations permanent income hypothesis repih of consumption we examine this and a number of related methodologicalissues for the uk using maximum likelihood estimation mle of an autoregressive fractionally integrated moving average arfima model of the income process we conclude that an innovation to income has a persistent effect on consumption and that in contrast to the findings from us studies consumption is too volatile compared to the repih model further mle is substantially more efficient than the semi parametric method of estimating arfima models which has previously been used in this area

cointegration fractional cointegration and exchange rate dynamics multivariate tests due to johansen 1988 1991 as implemented by baillie and bollerslev 1989a and diebold gardeazabal and yilmaz 1994 reveal mixed evidence on whether a group of exchange rates are cointegrated further analysis of the deviations from the cointegrating relationship suggests that it possesses long memory and may possibly be well described as a fractionally integrated process hence the influence of shocks to the equilibrium exchange rates may only vanish at very long horizons in the article by baillie and bollerslev 1989a it is argued that seven different nominal spot and forward exchange rates all contain unit roots in their univariate time series representations at the same time however the spot exchange rates appear to be tied together in the long run through a cointegration type relationship the latter finding of baillie and bollerslev has attracted particular interest and several studies such as those by hakkio and rush 1991 and sephton and larsen 1991 have already addressed this issue using the same data as the baillie and bollerslev article sephton and larsen 1991 describe the evidence for the presence of cointegration as being fragile and note that mixed conclusions are reached by truncating the baillie and bollerslev sample at different points in time diebold gardeazabal and yilmaz 1994 henceforth diebold et al provide interesting evidence that application of the johansen 1988 1991 tests with and without an intercept will result in different inferences on the baillie and bollerslev data set furthermore diebold et al carry out an ex ante forecasting experiment and find that the addition of an error correction term to the martingale model as implied by the standard cointegration paradigm fails to reduce the prediction mean square error when compared to a simple martingale model this therefore leads diebold et al to conclude that there exists substantial uncertainty regarding the existence of cointegration relationships among nominal dollar exchange rates this article provides some additional evidence on the existence of such a long run relationship among the same seven nominal spot exchange rates after further analysis it appears that a form of cointegration does exist between the exchange rates so that they do not drift apart in the long run we argue that this form of cointegration is

the risk free rate in heterogeneous agent incomplete insurance economies abstract why has the average real risk free interest rate been less than one percent the question is motivated by the failure of a class of calibrated representative agent economies to explain the average return to equity and risk free debt i construct an economy where agents experience uninsurable idiosyncratic endowment shocks and smooth consumption by holding a risk free asset i calibrate the economy and characterize equilibria computationally with a borrowing constraint of one year s income the resulting risk free rate is more than one percent below the rate in the comparable representative agent economy

the treasury yield curve as a cointegrated system this paper examines the temporal relationship between interest rates on treasury securities ranging in maturity from three months to 30 years we find strong empirical support that the seven treasury rates selected are cointegrated a conclusion that is insensitive to the normalization chosen in particular the hypothesis of noncointegration is rejeeted decisively regardless of the rate selected as the dependent variable in the cointegrating equation to determine whether this information can be used to improve forecasts of treasury rates the seven rates are forecasted with a corresponding erroreorrection model that is shown to outperform an augmented var model that ignores the cointegration of the rates the results are consistent with the belief that arbitrage limits the extent to which rates on different maturities of a given security diverge in addition the results confirm the appropriateness of imposing a common stochastic process for interest rates in equilibrium models of the term structure

efficiency aspects of the financing of unemployment insurance and other government expenditure this paper argues that if the disincentive effects of unemployment insurance result from higher reservation wages they may be eliminated by financing benefits with a progressive income tax the result is obtained within an equilibrium model with stochastic job matchings an optimal tax formula is derived for a linear income tax and shown to imply that the average tax rate should increase faster with income the higher the level of ui benefits relative to other government expenditure in some cases optimal financing may require the subsidization of low wage jobs

do long swings in the business cycle lead to strong persistence in output abstract this paper investigates how the occasional long swing in the business cycle can produce long memory behavior in us output to prove this theoretical relationship we extend the hamilton markov chain regime switching model of real aggregate output to include the occasional long regime we do this by modeling the duration length of the expansion and recession regimes as draws from a fat tailed distribution with realized durations that are high in variability and occasionally extreme in value empirically we find that the tail indices for the length of us economic booms and busts correspond with the long memory parameter estimates of diebold and rudebusch 1989 long memory and persistence in aggregate output journal of monetary economics 24 189 209 and sowell 1992a modeling long run behavior with the fractional arima model journal of monetary economics 29 277 302 for real us output estimates of our extended regime switching model produce better short and long run forecasts of output in comparison to forecasts with a fractionally integrated model furthermore our estimated regime switching model finds us expansions to be fragile during their infancy but become more and more likely to continue after surviving the first seven quarters

testing mean reversion in target zone exchange rates the aim of the paper is to assess to what extent european monetary system ems target zone exchange rates have been characterized by mean reverting behaviour to this purpose a new class of mean reversion tests is introduced with respect to standard approaches the proposed tests which are based on the sample excursion of the exchange rate within the band have a better ability to detect target zone mean reverting dynamics the empirical analysis of the exchange rates among the main ems currencies shows that the degree of mean reversion is much higher than what has been reported in the literature both before and after the target zone widening of 1993 finally the proposed tests have a wider range of applications since they originate a new approach to unit root testing

regional decentralization and fiscal incentives federalism chinese style abstract aligning the interests of local governments with market development is an important issue for developing and transition economies using a panel data set from china we investigate the relationship between provincial government s fiscal incentives and provincial market development we report three empirical findings first we find that during the period of fiscal contracting system the discrepancy between ex ante contracts and ex post implementation was relatively small suggesting that the fiscal contracts were credible second we find a much higher correlation about four times between the provincial government s budgetary revenue and its expenditure during 1980s and 1990s as compared to 1970s demonstrating that provincial governments faced much stronger ex post fiscal incentives after reform third we find that stronger ex ante fiscal incentives measured by the contractual marginal retention rate of the provincial government in its budgetary revenue are associated with faster development of the non state sector as well as more reforms in the state sector in the provincial economy this holds even when we control for the conventional measure of fiscal decentralization finally we compare federalism chinese style to federalism russian style

decentralization of governance and development all around the world in matters of governance decentralization is the rage even apart from the widely debated issues of subsidiarity and devolution in the european union and states rights in the united states decentralization has been at the center stage of policy experiments in the last two decades in a large number of developing and transition economies in latin america africa and asia the world bank for example has embraced it as one of the major governance reforms on its agenda for example world bank 2000 burki perry and dillinger 1999 take also the examples of the two largest countries of the world china and india decentralization has been regarded as the major institutional framework for the phenomenal industrial growth in the last two decades in china taking place largely in the nonstate nonprivate sector india ushered in a landmark constitutional reform in favor of decentralization around the same time it launched a major program of economic reform in the early 1990s on account of its many failures the centralized state everywhere has lost a great deal of legitimacy and decentralization is widely believed to promise a range of benee ts it is often suggested as a way of reducing the role of the state in general by fragmenting central authority and introducing more intergovernmental competition and checks and balances it is viewed as a way to make government more responsive and efe cient technological changes have also made it somewhat easier than before to provide public services like electricity and water supply relatively efe ciently in smaller market areas and the lower levels of government have now a greater ability to handle certain tasks in a world of rampant ethnic cone icts and separatist movements decentralization is also regarded as a way of diffusing social and political tensions and ensuring local cultural and political autonomy these potential benee ts of decentralization have attracted a very diverse range

long memory and persistence in aggregate output abstract we examine persistence in u s aggregate output by estimating fractionally integrated arima models these models provide better low frequency approximations to the wold representation than previous stochastic specifications and earlier results on the importance of a permanent component emerge as special cases we find evidence of long memory which induces persistence though this long memory need not be associated with a unit root our point estimates indicate that macroeconomic shocks while persistent are distinctly less persistent than many earlier studies suggest however confidence intervals associated with the long run response are quite wide

mean reversion in the real exchange rates abstract robinson s j am stat assoc 89 1994 1420 fractionally based tests for unit roots and other hypotheses are applied to real exchange rate data between u s and five industrialized countries the results indicate that the series are fractionally integrated with mean reversion if the disturbances are autocorrelated

long memory in inflation rates international evidence we examine monthly inflation rates of five industrial countries the application of tests against stationarity as well as tests against a unit root yield contradictory results thus fractional integration allowing for long memory is a plausible model we discuss and apply the periodogram regression to estimate the difference parameters for all countries we find estimates significantly different from 1 as well as from 0 this is evidence in favor of long memory specification tests and maximum likelihood estimates support the fitted models finally we relate our empirical results to the construction of the data

regional economic disparities and decentralisation the study of the influence of decentralisation on economic growth has received some attention in recent years but very few studies deal with its impact on regional inequalities this paper analyses the impact of both fiscal and political decentralisation on regional inequalities using alternative measures for a sample of 17 oecd countries in order to check for other possible influences the study also includes measures of public sector size and the type of party in government the final section studies the relevance of fiscal decentralisation in the regional convergence process observed by several authors during the past two decades the research reveals a strong negative correlation between decentralisation especially fiscal decentralisation and regional inequalities and also a positive influence of decentralisation on regional convergence

bidding structure market efficiency and persistence in a multi time tariff setting the purpose of this study is to examine the fractal dynamics of day ahead electricity prices by using parametric and semi parametric approaches for each time zone in a multi time tariff setting in the framework of bidding strategies market efficiency and persistence of exogenous shocks we find that that electricity prices have long term correlation structure for the first and third time zones indicating that market participants bid hyperbolically and not at their marginal costs market is not weak form efficient at these hours and exogenous shocks to change the mean level of prices will have permanent effect and be effective on the other hand for the second time zone we find that price series does not exhibit long term memory this finding suggests the weak form efficiency of the market in these hours and that market participants bid at their marginal costs furthermore this indicates that exogenous shocks will have temporary effect on electricity prices in these hours these findings constitute an important foundation for policy makers and market participants to develop appropriate electricity price forecasting tools market monitoring indexes and to conduct ex ante impact assessment

fractional integration trend stationarity and difference stationarity evidence from some u k macroeconomic time series fractionally integrated autoregressive moving average models are used to test trend stationarity and difference stationarity in the logarithms of five u k macroeconomic time series three series are found to be difference stationarity while the remaining two are best described by a nonstationary fractional model

the welfare cost of inflation under imperfect insurance abstract this paper examines the welfare cost of inflation in an economy where agents hold money in order to smooth consumption in the face of income variability for which there is no insurance the findings indicate that for the type of economies considered here the area under the empirical money demand curve is a poor measure of the welfare cost of inflation this area accounts for only one fourth of the true costs in the case of 5 inflation

bureaucratic corruption and the rate of temptation do wages in the civil service affect corruption and by how much abstract this paper presents what is to our knowledge the first empirical estimate of the effect of pay in the civil service on corruption first we show that theory is ambiguous on the relationship between civil service pay and corruption then we examine the issue using a new data set on wages for low income countries we find evidence of a statistically and economically significant relationship between relative civil service pay and corruption in regressions based on cross country averages where we control for a wide array of variables the relationship implies that a rather large increase in wages is required to eradicate corruption solely by raising wages

the injustice of inequality in many countries the operation of legal political and regulatory institutions is subverted by the wealthy and the politically powerful for their own benefit this subversion takes the form of corruption intimidation and other forms of influence we present a model of such institutional subversion focusing specifically on courts and of the effects of inequality in economic and political resources on the magnitude of subversion we then use the model to analyze the consequences of institutional subversion for the law and order environment in the country as well as for capital accumulation and growth we illustrate the model with historical evidence from gilded age united states and the transition economies of the 1990s we also present some cross country evidence consistent with the basic prediction of the model

education lifetime labor supply and longevity improvements this paper presents an analysis of the differential role of mortality for the optimal schooling and retirement age when the accumulation of human capital follows the so called ben porath mechanism we set up a life cycle model of consumption and labor supply at the extensive margin that allows for endogenous human capital formation this paper makes two important contributions first we provide the conditions under which a decrease in mortality leads to a longer education period and an earlier retirement age second those conditions are decomposed into a ben porath mechanism and a lifetime human wealth effect vs the years to consume effect finally using us and swedish data for cohorts born between 1890 and 2000 we show that our model can match the empirical evidence

the deaton paradox in a long memory context with structural breaks this article contributes to the permanent income hypothesis pih and excess consumption smoothness debate in the context of fractional integration we show that the excess consumption smoothness result is a consequence of the quarterly data frequency commonly employed in the empirical work in fact the i 1 hypothesis is rejected for the income process with monthly data in favour of a fractional integration order lower than 1 moreover if a structural break is taken into account we observe a substantial reduction in the degree of consumption smoothness especially after the break found in 1975

testing for cointegration power versus frequency of observation further monte carlo results abstract this paper studies the effects of increasing the frequency of observation and the data span on the johansen cointegration tests the ability of the tests to detect cointegration depends more on the total sample length than the number of observations

the effects of progressive income taxation on job turnover abstract we examine whether the level of the income tax rate and the convexity of the income tax schedule affect job mobility as measured by moving to a better job while the predicted effect of the level of the tax rate is ambiguous we predict that an increase in the convexity of the tax schedule decreases job search activity by taxing away some of the benefits of a successful job search using data from the panel study of income dynamics we estimate that both higher tax rates and increased tax rate progressivity decrease the probability that a head of household will move to a better job during the coming year our estimates imply that a five percentage point reduction in the marginal tax rate increases the average probability of moving to a better job by 0 79 percentage points a 8 0 increase in the turnover propensity and that a one standard deviation decrease in our measure of tax progressivity would increase this probability by 0 86 percentage points a 8 7 increase in the turnover propensity this estimate is robust to sensitivity analysis examining the importance of different sources of identification and variation in estimated effects across subgroups in the population our estimated importance of tax policy for job turnover suggests a potential role in explaining the responsiveness of taxable income to marginal tax rates

fiscal competition and the pattern of public spending much attention has been given to the impact of fiscal competition on the level of public expenditure but relatively little to the impact on its composition using a broadly familiar and reasonably rich model of fiscal competition in the presence of mobile capital this paper establishes a systematic bias in public spending patterns starting from the non cooperative equilibrium and holding tax rates constant welfare would be improved by a coordinated reduction in the provision of local public inputs and a corresponding increase in the public provision of local public goods benefiting immobile consumers c 1997 elsevier science s a

the swedish unemployment experience abstract since the 1960s sweden has sustained a remarkably low unemployment rate while the average duration of unemployment spells has been increasing over time this pattern is reproduced in an equilibrium search model incorporating progressive income taxes generous unemployment compensation and a program for preventing unemployed workers from abusing the system our analysis raises concerns about how well the swedish system is equipped to handle the current situation of high unemployment

options for economic and political reform in sweden sweden assar lindbeck per molander torsten persson olof peterson agnar sandmo birgitta swedenborg and niels thygesen this paper summarizes an official report to the swedish government and general public the economic crisis in sweden is explained by both system failures and specific policy mistakes the system failures include distorted incentives and markets and inappropriate and outdated institutions the deep recession and extraordinary rise in unemployment started as a collision between inflationary wage development and attempts to pursue a hard currency policy the resulting loss of international competitiveness in the tradable sector was accompanied by increased real interest rates collapsing real estate prices and a related financial crisis following the floating of the swedish krona in november 1992 the main problem became a domestic demand collapse which has been accentuated by a spectacular rise in the household saving rate the report emphasizes that good policy advice is not enough it is also necessary to analyse and reform the institutions which continually produce undesired outcomes with respect not only to macroeconomic stability but also economic efficiency and growth the proposed institutional reforms are designed to restore a highly competitive market system and to facilitate a responsible fiscal stabilization programme this would also enhance the medium run credibility of government policies and provide scope for a more expansionary policy in the short run

a comprehensive analysis of expenditure decentralization and of the composition of local public spending sacchi a and salotti s a comprehensive analysis of expenditure decentralization and of the composition of local public spending regional studies many industrialized countries have recently implemented fiscal decentralization reforms assigning more spending responsibility to sub national governments this paper investigates the causes of the decentralization of different categories of public expenditure in 19 developed countries over the period 1980 2006 different models for each of the spending functions under analysis are estimated adopting a general to specific empirical approach results confirm existing findings on the negative link between regional income disparities and expenditure decentralization a similarly negative relationship is found for a set of demographic variables leading to the conclusion that macroeconomic and more importantly political factors are responsible for the recent increase in decentralization finally the analysis is completed by a study of the factors driving sub n

maximum likelihood estimation of fractional cointegration with an application to u s and canadian bond rates we estimate a multivariate arfima model to illustrate a cointegration testing methodology based on joint estimates of the fractional orders of integration of a cointegrating vector and its parent series previous cointegration tests relied on a two step testing procedure and maintained the assumption in the second step that the parent series were known to have a unit root in our empirical example of fractional cointegration we illustrate how uncertainty regarding the order of integration of the parent series can be even more important than uncertainty regarding the order of integration of the cointegrating vector when testing for cointegration

multifractality in asset returns theory and evidence this paper investigates the multifractal model of asset returns mmar a class of continuous time processes that incorporate the thick tails and volatility persistence exhibited by many financial time series the simplest version of the mmar compounds a brownian motion with a multifractal time deformation prices follow a semi martingale which precludes arbitrage in a standard two asset economy volatility has long memory and the highest finite moments of returns can take any value greater than 2 the local variability of a sample path is highly heterogeneous and is usefully characterized by the local holder exponent at every instant in contrast with earlier processes this exponent takes a continuum of values in any time interval the mmar predicts that the moments of returns vary as a power law of the time horizon we confirm this property for deutsche mark u s dollar exchange rates and several equity series we develop an estimation procedure and infer a parsimonious generating mechanism for the e

long memory in foreign exchange rates using the geweke porter hudak test we find evidence of long memory in exchange rate data this implies that the empirical evidence of unit roots in exchange rates may not be robust to long memory alternatives fractionally integrated autoregressive moving average arfima models are estimated by both the time domain exact maximum likelihood ml method and the frequency domain approximate ml method impulse response functions and forecasts based on these estimated arfima models are evaluated to gain insight into the long memory characteristics of exchange rates some tentative explanations of the long memory found in the exchange rates are discussed

unemployment duration unemployment benefits and labor market programs in sweden abstract standard search theory as well as some empirical evidence suggest that an unemployed individual s probability of entering employment increases as he approaches the time when unemployment benefits are due to expire this pattern may not carry over to a country like sweden where labor market programs are targeted at the long term unemployed at risk of benefit exhaustion the paper examines transitions out of unemployment using data on unemployed individuals in sweden a semi parametric competing risks model for transitions to employment labor market programs and non participation is estimated there is some evidence that the exit rate from unemployment to employment increases as benefit exhaustion is approached

human capital and growth abstract this paper describes a growth model with the property that human capital accumulation can account for all observed growth the model is shown to be consistent with evidence on individual productivities as measured by census earnings data the central hypothesis is that we learn more when we interact with more productive people

misspecification versus bubbles in hyperinflation data monte carlo and interwar european evidence abstract this paper analyzes some new tests of the cagan hyperinflation money demand model which have several advantages relative to those in the literature they do not confound specification error with rational bubbles can be implemented with a linear procedure and are frequently able to detect periodically collapsing bubbles which have challenged existing tests after a monte carlo analysis the tests are applied to data from hyperinflations in austria germany hungary and poland evidence of misspecification is found for austria germany and hungary while the model without a rational bubble component appears to fit the data for poland

a fractional cointegration analysis of purchasing power parity a generalized notion of cointegration called fractional cointegration is introduced to examine the long run purchasing power parity ppp hypothesis by allowing deviations from equilibrium to follow a fractionally integrated process the fractional cointegration analysis can capture a wider range of mean reversion behavior than standard cointegration analyses this gain is flexibility in modeling subtle mean reverting dynamics is found to be important for a proper evaluation of long run ppp empirical results based on historical data for the 1914 1989 period show that ppp reversion exists and can be characterized by a fractionally integrated process in three out of five countries studied the results support ppp as a long run phenomenon though significant short run deviations from ppp can exist

long memory and fractional integration in the housing price series of london and paris this article deals with the analysis of house price indexes from a long range dependence viewpoint in particular it estimates the fractional differencing parameter in the london and paris house price series recognizing in some cases the potential seasonality and allowing for breaks in the data moreover it analyses the stability of the parameters across the sample period examined it is concluded that the series are nonstationary but mean reverting in some cases and very persistent in others policy implications are derived

some recent developments in futures hedging the use of futures contracts as a hedging instrument has been the focus of much research at the theoretical level an optimal hedge strategy is traditionally based on the expected utility maximization paradigm a simplification of this paradigm leads to the minimum variance criterion although this paradigm is quite well accepted alternative approaches have been sought at the empirical level research on futures hedging has benefited from the recent developments in the econometrics literature much research has been done on improving the estimation of the optimal hedge ratio as more is known about the statistical properties of financial time series more sophisticated estimation methods are proposed in this survey we review some recent developments in futures hedging we delineate the theoretical underpinning of various methods and discuss the econometric implementation of the methods

federalism and the soft budget constraint the government s incentives to bail out inefficient projects are determined by the trade off between political benefits and economic costs the latter depending on the decentralization of government two effects of federalism are derived first fiscal competition among local governments under factor mobility increases the opportunity costs of bailout and thus serves as a commitment device the competition effect second monetary centralization together with fiscal decentralization induces a conflict of interests and thus may harden budget constraints and reduce inflation the checks and balance effect the authors analysis is used to interpret china s recent experience of transition to a market economy copyright 1998 by american economic association

segregation and the quality of government in a cross section of countries we provide a new compilation of data on ethnic linguistic and religious composition at the subnational level for a large number of countries using these data we measure segregation of groups within the country to overcome the endogeneity problem that arises because of mobility and endogenous in ternal borders we construct an instrument for segregation we find that more ethnically and lin guistically segregated countries i e those where groups live more spatially separately have a lower quality of government there is no relationship between religious segregation and governance trust is an important channel of influence it is lower in more segregated countries jel hi 1 h77 j15 017 z12 z13 racial and religious conflicts are often associated with poor politicoeconomic performance especially in developing countries economists have recently turned their attention to ethnolinguistic fractionalization as an explanation of differences in the pace of development starting with an influential paper by william easterly and ross levine 1997 since then many others have shown that fractionalization is negatively correlated with a host of policy outcomes and the quality of government 1 however many ethnically diverse countries the united states for instance are quite successful what makes different countries more or less capable of handling

labour market policies and unemployment in the oecd unemployment policies richard jackman christopher pissarides and sawas savouri the massive increase in unemployment throughout the oecd since the early 1970s has led governments in many countries to introduce or to expand labour market policies such as training schemes employment subsidies public works or schemes of counselling or assistance in job search such programmes have the objective of reducing unemployment by improving the workings of the labour market after a description of these programmes this article proposes a framework based on the relationship between unemployment and vacancies or beveridge curve within which the rise in unemployment can be analysed and the effects of policies and of institutions examined this framework helps to identify the main factors which have affected the unemployment and vacancy rates in 14 of the main oecd countries over the period 1970 88 the main results are that while corporatism remains the institutional feature with the biggest single impact in sustaining low unemployment rates labour market policies also have had a significant and well defined effect on unemployment which appears large relative to the budgetary costs of the programmes

do global co2 emissions from fossil fuel consumption exhibit long memory a fractional integration analysis abstractin this article we use an autoregressive fractionally integrated moving average approach to measure the degree of fractional integration of aggregate world co2 emissions and its five components coal oil gas cement and gas flaring we find that all variables are stationary and mean reverting but exhibit long term memory our results suggest that both coal and oil combustion emissions have the weakest degree of long range dependence while emissions from gas and gas flaring have the strongest with evidence of long memory we conclude that transitory policy shocks are likely to have long lasting effects but not permanent effects accordingly permanent effects on co2 emissions require a more permanent policy stance in this context if one were to rely only on testing for stationarity and non stationarity one would likely conclude in favour of non stationarity and therefore that even transitory policy shocks have permanent effects our fractional integration analysis highlights that this i

the long memory of the forward premium abstract the estimation of arfima models by approximate maximum likelihood estimation methods reveals the forward premia for the currencies of canada germany and the uk vis a vis the us dollar to be well described by a fractionally integrated process these models imply that all the forward premia are mean reverting although their autocorrelations are quite persistent this degree of persistence has led other studies to erroneously conclude that the forward premia contains a unit root jel c22 e31

regional inequalities fiscal decentralization and government quality abstractregional inequalities fiscal decentralization and government quality regional studies there are theoretical arguments supporting the view that regional income inequalities the degree of fiscal decentralization and the quality of government are simultaneously determined this article argues that existing empirical work has failed to deal adequately with this possibility in light of this it applies a simultaneous equation model which accounts for the joint determination of these three variables to a panel of 23 organisation for economic co operation and development oecd countries the empirical evidence that emerges from the analysis suggests that a process of fiscal decentralization accompanied by measures to improve the quality of government would be an effective strategy for reducing regional inequalities

improving incentives in unemployment insurance a review of recent research abstract this paper provides a review of the recent literature on how incentives in unemployment insurance can be improved we are particularly concerned with three instruments i e the duration of benefit payments or more generally the time sequencing of benefits monitoring in conjunction with sanctions and workfare our reading of the theoretical literature is that the case for imposing a penalty on less active job search is fairly solid a growing number of empirical studies including randomized experiments are in line with this conclusion

what is fractional integration a simple construction that will be referred to as an error duration model is shown to generate fractional integration and long memory an error duration representation also exists for many familiar arma models making error duration an alternative to autoregression for explaining dynamic persistence in economic variables the results lead to a straightforward procedure for simulating fractional integration and establish a connection between fractional integration and common notions of structural change two examples show how the error duration model could account for fractional integration in aggregate employment and in asset price volatility

inequality and the territorial fragmentation of solidarity a long tradition of research has shown decentralized political struc tures as an important cause behind lower levels of redistribution and higher levels of inequality this article offers an alternative interpretation of the association between fragmented fiscal structures and higher levels of inequality i argue that the distribu tive effects of decentralization depend on the preexisting territorial patterns of inequal ity therefore the political choice between alternative fiscal structures is largely driven by their expected distributive consequences as a result the territorial structure of inequality becomes an important factor to explain why some fiscal structures are more integrated than others two mechanisms link regional income distributions and preferences about the decentralization of redistributive policy differences in the demand for redistribution associated with interregional income differences and dif ferences in the demand for social insurance associated with the incidence of labor market risks i test the argument using a data set of fourteen countries in the orga nization for economic cooperation and development oecd over the period 1980 2000 in addition i illustrate the potential of the approach by analyzing why social solidarity remains territorially fragmented in the european union despite the fact that it has a common currency and a common market

why countries are fiscally decentralizing this paper models and empirically investigates underlying forces that promote governmental decentralization or effective federalism in the world over the last 25 years a move to a federal system is based on the demand by hinterland regions for local autonomy which increases with national income growth greater relative hinterland population and increasing national population it is influenced as well by the degree of democratization nationally and locally decentralization is measured by both institutional indices indicating greater devolution of power to local governments and the share of local governments in national government consumption empirically the paper finds that decentralization changes in ways predicted in particular it increases with economic growth country size and population institutional structures based on colonial experience and initial constitutional provisions also matter

optimal residual based tests for fractional cointegration and exchange rate dynamics a lagrange multiplier test of the null hypothesis of cointegration in fractionally cointegrated models is proposed the test statistic uses fully modified residuals to cancel the endogeneity and serial correlation biases and standard asymptotic properties apply under the null and under local alternatives with iid gaussian errors the asymptotic gaussian power envelope of all unbiased tests is achieved by the one sided two sided test the finite sample properties are illustrated by a monte carlo study in an application to the dynamics among exchange rates for seven major currencies against the u s dollar mixed evidence of the existence of a cointegrating relation is found

a setar model for canadian gdp non linearities and forecast comparisons this paper investigates the forecasting performance of the non linear time series setar model by using canadian gdp data from 1965 to 2000 besides the within sample fit the forecasting performance of a standard linear arima model for the same sample has also been generated for comparative purposes two forecasting methods one step ahead and multi step ahead forecasting are compared for each type of model

incentives to provide local public goods fiscal federalism russian style abstract based on a unique data set on russian city budgets this paper shows that revenue sharing between regional and local governments provides local governments with no incentive to increase tax base or provide public goods any change in local government s own revenues is almost entirely offset by changes in shared revenues this leads to governmental over regulation of private businesses it is shown that fiscal incentives are a determinant of the formation of private business and the efficiency of public goods provision the russian federalism is compared to the chinese federalism where fiscal incentives reputedly are stronger in many provinces

political decentralization and corruption evidence from around the world abstract how does political decentralization affect the frequency and costliness of bribe extraction by corrupt officials previous empirical studies using subjective indexes of perceived corruption and mostly fiscal indicators of decentralization have suggested conflicting conclusions in search of more precise findings we combine and explore two new data sources an original cross national data set on particular types of decentralization and the results of a firm level survey conducted in 80 countries about firms concrete experiences with bribery in countries with a larger number of government or administrative tiers and given local revenues a larger number of local public employees reported bribery was more frequent when local or central governments received a larger share of gdp in revenue bribery was less frequent overall the results suggest the danger of uncoordinated rent seeking as government structures become more complex

modeling long run behavior with the fractional arima model abstract when modeling long run behavior fractional arima models can give insights unobtainable with the nonfractional arima models as an application the deterministic trend and unit root with drift models are nested in the fractional arima model this allows testing between the two models based on estimated parameter values this test is applied to postwar us quarterly real gnp the test concludes that gnp is consistent with both models the estimated fractional parameter is significantly smaller than reported in diebold and rudebusch 1989 the difference is explained by bias in the previous estimates relationships with the cumulative impulse response and spectral density at frequency zero are noted

labour supply search and taxes abstract classical labour supply theory is one of the most sophisticated parts of labour economics yet there is no compelling theoretical reason to believe in an outcome on a classical labour supply curve and it is unclear whether it is a good empirical description of the way in which labour markets actually work this paper uses the techniques of search theory to analyse the impact of changes in the tax system on incentives to work when individuals do not have flexibility of hours within jobs it is shown how the traditional comparative statics are of some use but are rarely the whole story and some comparative statics results are surprising

egalitarian wage policies and long term unemployment how does a centrally imposed egalitarian wage policy affect unemployment when workers differ with respect to productivity the effect on total unemployment is found to be ambiguous egalitarian wages encourage job creation because increased profits derived from the most productive workers more than outweigh reduced profits derived from the least productive workers short term unemployment is reduced on the other hand firms respond by raising their reservation productivity some workers are left almost completely unemployable long term unemployment rises less inequality in the wage distribution is obtained at the expense of more inequality in the distribution of unemployment

fractional monetary dynamics we test for fractional dynamics in us monetary series their various formulations and components and velocity series using the spectral regression method we find evidence of a fractional exponent in the differencing process of the monetary series both simple sum and divisia indices in their components with the exception of demand deposits savings deposits overnight repurchase agreements and term repurchase agreements and the monetary base and money multipliers no evidence of fractional behaviour is found in the velocity series granger s journal of econometrics 25 1980 aggregation hypothesis is evaluated and implications of the presence of fractional monetary dynamics are drawn

waves and persistence in merger and acquisition activity abstract markov regime switching and sine wave models have been used to capture the apparent wave like behavior in aggregate u s merger and acquisition m and a activity in this paper we offer an alternative characterization of the dynamic structure in m and a activity as a strongly dependent or long memory process

decentralization and corruption evidence across countries the relationship between decentralization of government activities and the extent of rent extraction by private parties is an important element in the recent debate on institutional design the theoretical literature makes ambiguous predictions about this relationship and it has remained virtually unexamined by empiricists the authors make a first attempt at examining the issue empirically by looking at the cross country relationship between fiscal decentralization and corruption as measured by a number of different indices their estimates suggest that fiscal decentralization in government spending is significantly associated with lower corruption moreover they find that the origin of a country s legal system for example civil versus common legal code performs extremely well as an instrument for decentralization the estimated relationship between decentralization when so instrumented and corruption is even stronger the evidence suggests a number of interesting areas for future work including investigating whether there are specific services for which decentralized provision has a particularly strong impact on political rent extraction and understanding the channels through which decentralization succeeds in keeping corruption in check

a pure jump transaction level price model yielding cointegration we propose a new transaction level bivariate log price model that yields fractional or standard cointegration the model provides a link between market microstructure and lower frequency observations the two ingredients of our model are a long memory stochastic duration process for the waiting times k between trades and a pair of stationary noise processes ek and k which determine the jump sizes in the pure jump log price process our model includes feedback between the disturbances of the two log price series at the transaction level which induces standard or fractional cointegration for any fixed sampling interval t we prove that the cointegrating parameter can be consistently estimated by the ordinary least squares estimator and we obtain a lower bound on the rate of convergence we propose transaction level method of moments estimators of the other parameters in our model and discuss the consistency of these estimators

the impact of vintage on the persistence of gross domestic product shocks abstract this paper aims to demonstrate that the data revision process affects the persistence of gross domestic product shocks results will contribute to the debate between unit root and linear models

a test for rational bubbles in the nasdaq stock index a fractionally integrated approach abstract in this paper we test for the presence of rational bubbles in the nasdaq stock market index over the period 1994 06 2003 11 by means of a methodology based on fractional processes the results suggest that the existence of bubbles depends on the sampling frequency used in the analysis we cannot reject the unit root hypothesis when using monthly data on price dividend ratios which according to the present value model suggests the existence of rational bubbles however we reject this hypothesis in favor of fractional alternatives when using daily and weekly data this might be explained by the temporal aggregation and or the sample sizes used in the application

hedging familiarity and portfolio choice we exploit the restrictions of intertemporal portfolio choice in the presence of non nancial income risk to design and implement tests of hedging that use the information contained in the actual portfolio of the investor we use a unique dataset of swedish investors with information broken down at the investor level and into various components of wealth investor income tax positions and investor demographic characteristics portfolio holdings are identi ed at the stock level we show that investors do not engage in hedging but invest in stocks closely related to their non nancial income we explain this with familiarity that is the tendency to concentrate holdings in stocks with which the investor is familiar in terms of geographical or professional proximity or that he has held for a long period we show that familiarity is not a behavioral bias but is information driven familiarity based investment allows investors to earn higher returns than they would have otherwise earned if they had hedged

on the persistence and volatility in european american and asian stocks bull and bear markets abstract in this paper we examine the statistical properties of several stock market indices in europe the us and asia by means of determining the degree of dependence in both the level and the volatility of the processes in the latter case we use the squared returns as a proxy for the volatility we also investigate the cyclical pattern observed in the data and in particular if the degree of dependence changes depending on whether there is a bull or a bear period we use fractional integration and garch specifications the results indicate that the indices are all nonstationary i 1 processes with the squared returns displaying a degree of long memory behaviour with respect to the bull and bear periods we do not observe a systematic pattern in terms of the degree of persistence though for some of the indices ftse dax hang seng and sti there is a higher degree of dependence in both the level and the volatility during the bull periods

testing for persistence in housing price to income and price to rent ratios in 16 oecd countries housing price to income and price to rent ratios are among the most widely monitored indicators of housing market conditions while these ratios tend to fluctuate around a constant level or a mild trend over the long term they also tend to deviate from these benchmarks for protracted periods traditional unit root tests often indicate the presence of a unit root this article uses the framework of fractional integration to test the persistence of price to income and price to rent ratios in a sample of 16 oecd countries spanning four decades the results indicate that the ratios are highly persistent the possibility that persistence estimates may be affected by structural breaks in the series is also considered but evidence of such breaks is found only in a very limited number of cases policy action may be required if high price to income and price to rent ratios have adverse social and economic consequences policies should be guided by a careful analysis of the factors behind high ratios
