a model based indicator of the fiscal stance we argue that the conventional approach to assessing the fiscal stance based on econometric tests of the government present value budget constraint pvbc is of limited practical use we propose an alternative measure that focuses on short run fluctuations in the fiscal stance namely a model based indicator that compares a target level of the debt gdp ratio at a given point in the future with a forecast based on the government budget constraint gbc where the forecasts are obtained using a recursively estimated var by log linearising the gbc the index can be decomposed into the various different components of which it is comprised using data from 1970 to 2011 we conduct a detailed time series study of the fiscal stances of four countries the united states the united kingdom germany and greece and we calculate the index for 11 other eu countries for most countries the index shows that their fiscal stances vary from being too loose to too tight almost without exception the index drops sharply from 2007 showing the harmful effect on their fiscal stances of the recent recession

the tail index of exchange rate returns in the literature on the empirical distribution of foreign exchange rates there is now consensus that exchange rate yields are fat tailed three problems however persist 1 which class of distribution functions is most appropriate 2 are the parameters of the distribution invariant over subperiods 3 what are the effects of aggregation over time on the distribution in this paper we employ extreme value theory to shed new light on these questions we apply the theoretical results to ems data

more mortgages lower growth in newly collected data on 46 economies over 1990 2011 we show that financial development since 1990 was mostly due to growth in credit to real estate and other asset markets which has a negative growth coefficient we also distinguish between growth effects of stocks and flows of credit we find positive growth effects for credit flows to nonfinancial business but not for mortgage and other asset market credit flows by accounting for the composition of credit stocks and for the effect of credit flows we explain the insignificant or negative growth effects of financial development in recent times what was true in the 1960s 1970s and 1980s when the field of empirical credit growth studies blossomed is no longer true in the 1990s and 2000s new bank lending is not primarily to nonfinancial business and financial development may no longer be good for growth these trends predate the 2008 crisis they prompt a rethink of the role of banks in the process of economic growth jel e44 o16 o40 c33

rising inequality as a cause of the present crisis the article argues that the economic imbalances that caused the present crisis should be thought of as the outcome of the interaction of the effects of financial deregulation with the macroeconomic effects of rising inequality in this sense rising inequality should be regarded as a root cause of the present crisis i identify four channels by which it has contributed to the crisis first rising inequality creates a downwards pressure on aggregate demand since poorer income groups have high marginal propensities to consume second international financial deregulation has allowed countries to run larger current account deficits and for longer time periods thus in reaction to potentially stagnant demand two growth models have emerged a debt led model and an export led model third in the debt led growth models higher inequality has led to higher household debt as working class families have tried to keep up with social consumption norms despite stagnating or falling real wages fourth rising inequality has increased the propensity to speculate as richer households tend to hold riskier financial assets than other groups the rise of hedge funds and of subprime derivatives in particular has been linked to rise of the super rich

financialisation income distribution and aggregate demand in the usa this paper investigates the effects of financialisation and functional income distribution on aggregate demand in the usa by estimating the effects of the increase in rentier income dividends and interest payments and housing and financial wealth on consumption and investment the redistribution of income in favour of profits suppresses consumption whereas the increase in the rentier income and wealth has positive effects a higher rentier income decreases investment without the wealth effects the overall effect of the changes in distribution on aggregate demand would have been negative thus a pro capital income distribution leads to a slightly negative effect on growth i e the usa economy is moderately wage led

the behavior of extreme values in germany s stock index futures an application to intradaily margin setting recent defaults and large financial losses attributed to derivative security investing point to an area of finance not often researched i e the probabilities of observing extreme occurrences this paper examines this behavior for german stock index futures fdax contracts its empirical results indicate that large fdax intradaily price changes follow a frechet extreme value distribution and the extreme value distribution probabilities may be confidently used to help set intradaily margin levels

heterogeneous information arrivals and return volatility dynamics uncovering the long run in high frequency returns recent empirical evidence suggests that the interdaily volatility clustering for most speculative returns are best characterized by a slowly mean reverting fractionally integrated process meanwhile much shorter lived volatility dynamics are typically observed with high frequency intradaily returns the present article demonstrates that by interpreting the volatility as a mixture of numerous heterogeneous short run information arrivals the observed volatility process may exhibit long run dependence as such the long memory characteristics constitute an intrinsic feature of the return generating process rather than the manifestation of occasional structural shifts these ideas are confirmed by our analysis of a one year time series of fiveminute deutschemark u s dollar exchange rates among the most puzzling issues is the behavior of volatility while the general properties of volatility remain elusive perhaps the most intriguing feature revealed by empirical work on volatility is its long persistence such behavior has sparked a search almost akin to that for the holy grail for the perfect garch model but the underlying question of why such volatility persistence endures remains unanswered we conjecture that the ability to analyze higher frequency data may be particularly useful in pursuing this issue goodhart and o hara 1997 the pronounced volatility clustering is arguably one of the most striking features of financial price series recorded at daily or weekly intervals and a large body of literature seeking to characterize this aspect of speculative returns has emerged over the past decade 1 at the same time convincing theoretical explanations for the underlying sources of long run persistence in volatility remain elusive the recent advent of comprehensive high frequency andersen is from the j l kellogg graduate school of management of northwestern university bollerslev is from the university of virginia and is a research associate at the national bureau of economic research we gratefully acknowledge the financial support provided by a research grant from the institute for quantitative research in finance the q group special thanks are due to olsen and associates for making the intradaily exchange rate quotes and reuter s news tape available we have received valuable comments from wake epps clive w j granger stephen f gray j huston mcculloch as well as seminar participants at the december 1996 triangle econometrics workshop the 1997 afa meetings in new orleans academia sinica the wharton school usc and georgetown and york universities we remain fully responsible for the content 1 see bollerslev chou and kroner 1992 for a survey of this literature using arch type

animal spirits in the foreign exchange market it is traditionally assumed in finance models that the fundamental value of an asset is known with certainty in this paper we depart from that assumption we propose a simple model of the exchange rate in which agents have biased and unbiased beliefs about the fundamental rate we show that such a model produces waves of optimism and pessimism unrelated to the underlying fundamental value in addition the model shows that in a world characterized by the existence of heterogeneous beliefs about the fundamental exchange rate movements can be remarkably complex even if only fundamentalist traders operate in the market

the stability pact more than a minor nuisance stability pact more than a minor nuisance the stability and growth pact will lead member countries to aim for cyclically balanced budgets until this steady state is reached europe will continue its efforts at de cit cutting while so doing politicians are less likely to undertake the dif cult labour market reforms that are really needed is further scal retrenchment wise the paper reviews the reasons that have been advanced in favour of a stability pact and nds them wanting the most serious justi cations such as the systemic risk of bank crisis following a government s failure to service its debt can be better dealt with in other ways for example by prudential limits on banks exposure to public debts moreover our analysis reveals that the macroeconomic costs of the stability pact while sizeable are not as dangerous as often believed the costs will be barely visible once the steady state is reached the true macroeconomic costs are front loaded they concern the next few years after a decade already dominated by convergence efforts barry eichengreen and charles wyplosz

macroeconomics after the crisis time to deal with the pretense of knowledge syndrome the recent financial crisis has damaged the reputation of macroeconomics largely for its inability to predict the impending financial and economic crisis to be honest this inability to predict does not concern me much it is almost tautological that severe crises are essentially unpredictable for otherwise they would not cause such a high degree of distress what does concern me about my discipline is that its current core by which i mainly mean the so called dynamic stochastic general equilibrium approach has become so mesmerized with its own internal logic that it has begun to confuse the precision it has achieved about its own world with the precision that it has about the real one this is dangerous for both methodological and policy reasons to be fair to our field an enormous amount of work at the intersection of macroeconomics and corporate finance has been chasing many of the issues that played a central role during the current crisis including liquidity evaporation collateral shortages bubbles crises panics fire sales risk shifting contagion and the like however much of this literature belongs to the periphery of macroeconomics rather than to its core i will discuss the distinction between the core and the periphery of macroeconomics as well as the futile nature of the integrationist movement that is the process of gradually bringing the insights of the periphery into the dynamic stochastic general equilibrium structure i argue that the complexity of macroeconomic interactions limits the knowledge we can ever attain and that we need to place this fact at the center of our analysis we should consider what this complexity does to the actions and reactions of the economic agent and seek analytical tools and macroeconomic policies that are robust to the enormous uncertainty to which we are confined

the distribution of exchange rate returns and the pricing of currency options an empirical model of the distribution of exchange rate returns based on a combination of the generalized student t distribution and conditional variance specifications is formulated and estimated for four daily bilateral exchange rates over the period 1984 to 1991 the empirical results show that the stylized characteristics of exchange rate returns such as volatility clustering leptokurtosis and skewness are consistently captured by this model in contrast with other model specifications based on more restrictive distributional assumptions implications of the analysis are also investigated for the pricing of currency options including comparisons with black scholes prices

beyond dsge models toward an empirically based macroeconomics david colander has been writing about economic methodology for over 30 years but he goes out of his way to emphasize that he does not see himself as a methodologist his pragmatic methodology is applicable to what economists are doing and attempts to answer questions that all economists face as they go about their work the articles collected in this volume are divided with the first part providing a framework underlying colander s methodology and introducing colander s methodology for economic policy within that framework part two presents colander s view on the methodology for microeconomics while part three looks at colander s methodology for macroeconomics the book closes with discussions of broader issues this abstract was borrowed from another version of this item

post keynesian stock flow consistent modelling a survey the aim of the paper is to provide an overview of the current stock ow consistent sfc literature indeed we feel the sfc approach has recently led to a blossoming literature requiring a new summary after the work of dos santos and above all after the publication of the main reference work on the methodology godley and lavoie s monetary economics an integrated approach to credit money income production and wealth the paper is developed along the following lines first a brief historical analysis investigates the roots of this class of models that can be traced as far back as 1949 and the work of copeland second the competing points of view regarding some of its main controversial aspects are underlined and used to classify the different methodological approaches followed in using these models namely we discuss i how the models are solved ii the treatment of time and its implication and ii the need or not for microfoundations these results are then used in the third section of the paper to develop a bifocal perspective which allows us to divide the literature reviewed according to both its subject and the methodology we explore various topics such as financialisation exchange rate modelling policy implication the need for a common framework within the post keynesian literature and the empirical use of sfc models finally the conclusions present some hypotheses and wishes for the possible lines of development of sfc models

fiscal deficits output growth and inflation targets in ghana abstract inflation appears to be the macro problem for which no antidote has been found under the economic recovery programme it is possible that either a wrong diagnosis has been made of the problem or that certain factors within the economy are preventing inflation from staying within target levels using an error correction model ecm the paper estimates an inflation equation for ghana the convenience of this model is in the fact that all the data series exhibit an autoregressive scheme of order one that is they are i 1 series in such an instance the granger engle theorem shows that the ecm provides the most efficient model further the ecm unveils some of the short run dynamics which are missing in other estimation techniques the results of the econometric regression show that inflation in ghana either in the long run or short run is influenced more by output volatility than by monetary factors an examination is made of the consistency of fiscal deficit the hypothesis is that an unsustainable fiscal policy would make government miss some macroeconomic targets it is shown that in 1985 and 1989 fiscal policy was consistent inflation was well within target in 1985 for 1986 1988 the government did not maintain consistent fiscal deficits and inflation in those years was well above targets it is recommended that to control inflation in ghana more attention should be paid to supply factors further government should pursue consistent fiscal policies

tail behaviour of the euro this paper empirically analyses risk in the euro relative to other currencies comparisons are made between a subperiod encompassing the final transitional stage to full monetary union with a subperiod prior to this stability in the face of speculative attack is examined using extreme value theory to obtain estimates of tail exchange rate changes the findings are encouraging the euro s common risk measures do not deviate substantially from other currencies also the euro is stable in the face of speculative pressure for example the findings consistently show the euro being less risky than the yen and having similar inherent risk to the deutsche mark the currency that it is essentially replacing

the statistical distribution of exchange rates empirical evidence and economic implications the abundant evidence that changes in exchange rates have distributions with fatter tails than the normal distribution has led researchers to consider non normal distributions including the student the stable paretian and mixtures of distributions this paper compares the empirical fits of three non normal candidates and the normal distribution for daily changes in the logarithms of exchange rates using maximum likelihood estimation of the parameters and chi square goodness of fit tests the student and mixture of two normals provide the best fits but there is evidence that the distribution parameters may vary over time

a monetary minsky model of the great moderation and the great recession abstract steve keen s model of minsky s financial instability hypothesis keen 1995 displayed qualitative characteristics that matched the real macroeconomic and income distributional outcomes of the preceding and subsequent fifteen years a period of economic volatility followed by a period of moderation leading to a rise of instability once more and a serious economic crisis this paper extends that model to build a strictly monetary macroeconomic model which can generate the monetary as well as the real phenomena manifested by both the great recession and the great moderation

income distribution and macroeconomics this paper analyzes the role of wealth distribution in macroeconomics through investment in human capital it is shown that in the presence of credit markets imperfections and indivisibilities in investment in human capital the initial distribution of wealth affects aggregate output and investment both in the short and in the long run as there are multiple steady states this paper therefore provides an additional explanation for the persistent differences in per capita output across countries furthermore the paper shows that cross country differences in macroeconomic adjustment to aggregate shocks can be attributed among other factors to differences in wealth and income distribution across countries

the consequences of fiscal stimulus on public debt a historical perspective the current policy agenda of neoclassical macroeconomics as expressed within conservative political circles in the uk and european union is that fiscal contraction is the lever that can bring about recovery from the current economic downturn allegedly the reason is that when business sees that the government balance sheet is improving and public debt declining there will be greater confidence in the country s economic prospects and this increased confidence will lead to higher investment this in turn will lead to growth and the road to economic recovery this study examines the impact of government stance on public debt for 11 oecd countries for which data on the relevant factors are available from 1881 to 2011 contrary to traditional predictions it turns out that over this long historical span fiscal contractions deteriorated rather than improved public debt as a percentage of gdp this implies that fiscal austerity exacerbates the lack of demand and deteriorates rather than enhances the prospects of economic recovery

a macroeconomic model with a financial sector this paper studies a macroeconomic model in which financial experts borrow from less productive agents we pursue four sets of results i the economy is prone to instability and occasionally enters volatile episodes as volatility spikes agents precautionary motive increases depressing prices even further log linear approximations fail to capture these non linear effects that can cause economies to be significantly depressed for long periods of time ii endogenous risk during volatile episodes increases asset price correlations iii financial experts impose a negative externality on each other and on the labor sector by not maintaining adequate capital cushion and funding structure iv while risk sharing within the financial sector through securitization and derivatives contracts reduces many inefficiencies it can also amlify systemic risks

testing the martingale hypothesis in deutsche mark futures with models specifying the form of heteroscedasticity summary we examine the form of heteroscedasticity in deutsche mark futures price data and compare different specifications of the particular way that the variance is changing over time the martingale hypothesis is tested with daily and weekly rates of change of futures prices for the deutsche mark and some evidence is found against this hypothesis in analyses of daily data from 1981 to 1985 this rejection of the martingale hypothesis may be attributed to trading day effects in foreign currency prices and the resulting day of the week patterns in futures prices when the martingale hypothesis is tested with weekly data the null hypothesis is retained

a survey of recent developments in the literature of finance and growth this paper provides a survey of the recent progress in the literature of financial development and economic growth the survey highlights that most empirical studies focus on either testing the role of financial development in stimulating economic growth or examining the direction of causality between these two variables although the positive role of finance on growth has become a stylized fact there are some methodological reservations about the results from these empirical studies several key issues unresolved in the literature are highlighted the paper also points to several directions for future research

on a simple rule for the optimal inflation rate in second best taxation abstract the optimal inflation rate is analyzed in the framework of dynamic second best with endogenous factor prices it is shown that when the marginal excess burden of taxation is relatively small the optimal inflation rate is approximated by a simple rule the paper also analyzes the robustness of this rule to the specification of the model money as an input in utility or production

trade in financial services capital flows and the value at risk of countries in light of the recent financial crises in the emerging markets the coming into force of the financial services agreement under the gats has been considered a success while the agreement provides for little new liberalization but rather formalizes the status quo it was feared that governments could even backtrack on previous commitments in the belief that more open markets could increase the degree of susceptibility by undermining financial stability strengthening the financial system s ability to evaluate and manage risk has therefore been identified as a precondition for more ambitious liberalization efforts in the future dobson and jacquet 1998 encouragingly in some countries banks have begun to implement value at risk approaches as a tool to assess their balance sheet vulnerability as this paper argues such an approach could also play a useful role in determining the extent of market risk on the macroeconomic level with potentially important implications regarding trade in financial services capital account convertibility and international crisis management

debt deficits and inflation an application to the public finances of india abstract the paper studies the solvency of the indian public sector and the eventual monetization and inflation that would be implied by stabilization of the debt gnp ratio in the absence of changes in the primary deficit the nonstationarity of the discounted public debt suggests that indefinite continuation of the pattern of behavior reflected in the historical time series process is inconsistent with the maintenance of solvency this message is reinforced by the recent behavior of the debt gnp ratio and of the ratio to gnp of the sum of the primary budget surplus and seigniorage our estimates of the base money demand function suggests that even maximal use of the inflation tax would not be sufficient to restore solvency measures to reduce the primary deficit are therefore unavoidable

poincare s stabilization abstract the data and press commentaries studied in this paper call for a reinterpretation of the french inflationary crisis and its stabilization in 1926 in contrast with sargent s interpretation there is evidence that the budgetary situation was well in hand and that only fear of a capital levy made the public unwilling to buy government bonds as a result the government had to repay the bonds coming to maturity with monetary financing only when poincare introduced a bill to shift the tax burden off bondholders did the demand for government bonds recover and inflation stop

a guide to public sector debt and deficits government deficits reinterpreted willem h buiter public sector debt and deficits are a matter of concern to governments throughout the world after presenting data on the public debt and deficits in the uk and abroad this paper considers four key issues first does an increase in the budget deficit today make an increase in inflation in the future more likely in economies like the uk the answer is no because the scope for raising revenue by money creation is limited compared to raising taxes second how does one evaluate the consistency of a given spending and tax programme a number of measures are presented which indicate the adjustment that must be made to spending and tax plans if the government is to remain solvent third it is often argued that an increase in budget deficits will merely crowd out private spending the paper shows that the truth of this proposition depends critically on the state of the economy the time horizon and whether the increased deficit is temporary or permanent finally the question of deriving a suitable measure of fiscal stance is considered developing an index of fiscal impact requires a suitable economic model and a number of different measures are considered and criticized conventional deficit measures whether actual cyclically corrected or inflation corrected are a poor indicator of the government s true fiscal stance

extremal analysis of currency crises in taiwan we employ extreme value theory to identify currency crises in taiwan the new approach is able to identify severe currency crises and at the same time avoid the crisis misclassification problem of markov switching models signal accounting indicates that currency crises in taiwan are preceded by rapid expansion of domestic credit and other monetary aggregates implying that financial excesses stressed by the third generation crisis model are the main causes of these currency crises

estimating the density tail index for financial time series the tail index of a density has been widely used as an indicator of the probability of getting a large deviation in a random variable most of the theory underlying popular estimators of it assume that the data are independently and identically distributed i i d however many recent applications of the estimator have been to financial data and such data tend to exhibit long range dependence we show via monte carlo simulations that conventional measures of the precision of the estimator which are based on the i i d assumption are greatly exaggerated when such dependent data are used this conclusion also has implications for estimates of the likelihood of getting some extreme values and we illustrate the changed conclusions one would get using equity return data

optimal fiscal and monetary policy in an economy without capital abstract this paper is concerned with the structure and time consistency of optimal fiscal and monetary policy in an economy without capital in a dynamic context optimal taxation means distributing tax distortions over time in a welfare maximizing way for a barter economy our main finding is that with debt commitments of sufficiently rich maturity structure an optimal policy if one exists is time consistent in a monetary economy the idea of optimal taxation must be broadened to include an inflation tax and we find that time consistency does not carry over an optimal inflation tax requires commitment by rules in a sense that has no counterpart in the dynamic theory of ordinary excise taxes the reason time consistency fails in a monetary economy is that nominal assets should from a welfare maximizing point of view always be taxed away via an immediate inflation in a kind of capital levy this emerges as a new possibility when money is introduced into an economy without capital

prudent margin levels in the finnish stock index futures market futures market officials are confronted with the difficult task of setting appropriate margin levels that must balance the costs of trader default and the benefits of increased market liquidity one way to guard against default is prudent margin setting practices designed to protect futures positions from extreme price movements the objective of this research is to extrapolate the probabilities of encountering extreme price movements by applying statistical extreme value theory to the finnish stock index futures market the extreme value technique is found to be appropriate since it generates theoretical margin violation probabilities that closely follow the empirical probability distribution the extrapolated results provide decision makers information on extreme events that have not yet occurred

testing for multiple regimes in the tail behavior of emerging currency returns it is by now generally accepted that foreign exchange returns exhibit heavy tails as measured by the so called tail index however it is unclear whether the tail behavior remains stationary in the presence of recurrent switches in the exchange rate regime we therefore test the null hypothesis of tail index constancy by applying a single breaks test in rounds which enables the detection of multiple breakpoints we are able to identify multiple jumps in the tail index of currency returns moreover some breaks coincide with documented shifts in monetary and exchange rate policies

assessing the fiscal stance in the european union and the united states 1970 2011 the huge increases in debt gdp ratios following the 2007 2009 global financial crisis which are unprecedented except in times of war has focused attention on the viability of the fiscal positions of eu countries and the us how to assess this and the likely future evolution of these positions this paper proposes an indicator of the fiscal stance which computes the fiscal adjustment required to reach a specific debt gdp targeted given the forecasts of future deficit and interest rates obtained from an unrestricted recursively estimated var model the index is easy to compute and can be decomposed to disclose the different contribution of revenue expenditure nominal yields inflation and growth to the fiscal stance for this reason it provides a transparent and detailed measure of the fiscal stance particularly suitable for multi country surveillance as a result the index improves on the tax gap indicators widely used by governments and international agencies and is far more informative than formal econometric tests of fiscal sustainability the time series of the indicator for individual eu countries and the us show that their fiscal position has fluctuated considerably over the last 40 years and has particularly deteriorated since 2007 the index predicts that the adjustment required to restore pre crisis debt gdp levels are higher for high debt countries like greece italy and portugal they become more severe the shorter is the time horizon for the adjustment as a large degree of uncertainty surrounds the assessment of the fiscal stance in the medium and long run we argue that policy makers should inform their policy based on the worst case scenario predicted by the indicator

is the euro zone on the mend latin american examples to analyze the euro question several european countries face challenges reminiscent of those faced by the emerging economies of latin america the economic booms in some peripheral euro zone countries financed by large capital inflows the credit and asset price booms and then the busts including sudden stops in capital flows the strong interaction between sovereign debt and domestic banking systems the role of foreign banks and contagion and all in the context of a fixed exchange rate are familiar plotlines for latin american audiences for those euro zone countries that built up large euro denominated external liabilities latin america s experience is particularly relevant and worrisome still europe may be in a better position to navigate a path out of the crisis given cooperative mechanisms that were absent in latin america particularly the availability of massive liquidity support nonetheless while such support buys time it does not guarantee success this paper argues that reflecting on latin america s experience provides useful lessons for europe to improve the chances for a successful resolution

a simple model of three economies with two currencies the eurozone and the usa this paper presents a keynesian model which describes three countries trading merchandise and financial assets with one another it is initially assumed that all three countries have independent fiscal policies but that two of the countries share a currency hence the model can be used to make a preliminary analysis of the conduct of economic policy in the eurozone vis a vis the rest of the world the usa the main conclusion will be that if all three countries do indeed operate independent fiscal policies the system will work under a floating currency regime but only so long as the european central bank is prepared to modify the structure of its assets by accumulating an ever rising proportion of bills issued by any weak euro country

differences between foreign exchange rate regimes the view from the tails abstract in the literature on the empirical unconditional distribution of foreign exchange rate returns there is indication that the type of distribution function is related to the form of exchange rate regime the analysis has been hampered by the nonnestedness of alternative distribution models the paper investigates the issue by means of extremal analysis which allows for a unified treatment in particular we try to sort out whether apparent distributional differences are due to differences in techniques or in regimes jel f31 f33

the nature and role of monetary policy when money is endogenous this paper considers the nature and role of monetary policy when money is modelled as credit money endogenously created within the private sector there are currently two schools of thought that view money as endogenous one has been labelled the new consensus in macroeconomics and the other is the keynesian endogenous bank money approach the paper first explores the analysis of monetary policy in the new consensus macroeconomic model followed by an examination of the effectiveness of monetary policy in that analysis the keynesian view of endogenous money is discussed and the role for monetary policy in a keynesian endogenous monetary policy analysis is considered including discussion of the objectives and instruments of monetary policy copyright 2006 oxford university press

a closer look at financial development and income distribution this paper analyzes the under investigated relationship uniting financial development and income distribution we use a novel approach taking into account for the first time the specific channels linking banks capital markets and income inequality the time varying nature of the relationship and reciprocal causality we construct a set of annual indicators of banking and capital market size robustness efficiency and international integration we then estimate the determinants of income distribution using a panel bayesian structural vector autoregressive svar model for a set of 49 countries over the 1994 2002 period we uncover a significant causality running from financial sector development to income distribution in addition the banking sector seems to exert a stronger impact on inequality finally the relationship appears to depend on characteristics of the financial sector rather than on its size

mixed diffusion jump process modeling of exchange rate movements this study demonstrates that the mixed diffusion jump process is superior to the stable laws or a mixture of normals as a model of exchange rate changes for the british pound french franc and the we st german mark relative to the united states dollar the parameter value s for the mixed diffusion jump process are dependent on the monetary policy regime in force in the united states with the estimates for the franc and mark being intertemporally similar but different from the pound copyright 1988 by mit press

top incomes in the long run of history a recent literature has constructed top income shares time series over the long run for more than twenty countries using income tax statistics top incomes represent a small share of the population but a very significant share of total income and total taxes paid hence aggregate economic growth per capita and gini inequality indexes are sensitive to excluding or including top incomes we discuss the estimation methods and issues that arise when constructing top income share series including income definition and comparability over time and across countries tax avoidance and tax evasion we provide a summary of the key empirical findings most countries experience a dramatic drop in top income shares in the first part of the twentieth century in general due to shocks to top capital incomes during the wars and depression shocks top income shares do not recover in the immediate postwar decades however over the last thirty years top income shares have increased substantially in english speaking countries and in india and china but not in continental european countries or japan this increase is due in part to an unprecedented surge in top wage incomes as a result wage income comprises a larger fraction of top incomes than in the past finally we discuss the theoretical and empirical models that have been proposed to account for the facts and the main questions that remain open

modeling private investment in egypt abstract this paper presents an empirical model of private investment that takes into account certain features of a developing economy such as the oligopolistic structure of markets putty clay technology the inelastic supply of non traded capital goods and financial repression the model is tested on egyptian data using error correction and cointegration the results for egypt indicate that at the macroeconomic level private investment depends on mark ups internal financing demand and the cost of investment goods defined not as the interest rate but as the outcome of the interaction of supply and demand in the market for capital goods the effects of government policy on private investment are mixed with some evidence of crowding out in credit markets and of crowding in as a result of government investment in infrastructure

modeling heteroscedasticity in daily foreign exchange rates this article estimates autoregressive conditionally heteroscedastic arch and generalized arch garch models for five foreign currencies using 10 years of daily data a variety of arch and garch specifications a number of nonnormal error densities and a comprehensive set of diagnostic checks it finds that arch and garch models can usually remove all heteroscedasticity in price changes in all five currencies goodness of fit diagnostics indicate that exponential garch with certain nonnormal distributions fits the canadian dollar extremely well and the swiss franc and the deutsche mark reasonably well only one nonnormal distribution fits the japanese yen reasonably well none fit the british pound

the rise in unemployment a multi country study one of the most remarkable features of recent economic history has been the remorseless rise in unemployment throughout the industrialized countries however while the trend to higher unemployment is universal the experience of individual countries also differs widely the increase is especially marked within the european community where unemployment rates rival those reached in the interwar years by contrast in the scandinavian countries and japan unemployment is lower and has risen very much less experience in the united states lies somewhere between these extremes and in the last few years unemployment there has fallen sharply

the probability distribution of foreign exchange price changes tests of candidate processes this study investigates empirically candidate processes for characterizing foreign exchange price changes measured over limited horizons extant empirical studies find distributions of exchange returns too long tailed and leptokurtic to satisfy normality four processes are investigated here because of their potential to model o bserved discontinuities in exchange rates and nonstationary sample moments as well as their economic appeal the results favor a mixed jump model for all six major trading currencies tested copyright 1988 by mit press

what is happening to the impact of financial deepening on economic growth i introduction among the strongest elements of the modern economists canon is that financial sector development has a significant impact on economic growth a generation ago economists like goldsmith 1969 1 and mckinnon 1973 began to draw attention to the benefits of financial structure development and financial liberalization by the early 1990s mckinnon 1991 12 could write with confidence that now however there is widespread agreement that flows of saving and investment should be voluntary and significantly decentralized in an open capital market at close to equilibrium interest rates since the 1990s a burgeoning empirical literature has illustrated the importance of financial sector development for economic growth despite the growing consensus however we find that the link between finance and growth in cross country panel data has weakened considerably over time at the very time that financial sector liberalization spread around the world the influence of financial sector development on economic growth has diminished the seminal empirical work that established the growth finance link is king and levine 1993 which extended the cross country framework introduced in barro 1991 by adding financial variables such as the ratios of liquid liabilities or claims on the private sector to gross domestic product gdp to the standard growth regression they found a robust positive and statistically significant relationship between initial financial conditions and subsequent growth in real per capita incomes for a cross section of about 80 countries in the subsequent decade numerous empirical studies expanded upon this using both cross country and panel data sets for the post 1960 period 2 in this paper we reexamine the core cross country panel result and find that the impact of financial deepening on growth is not as strong with more recent data as it appeared in the original panel studies with data for the period from 1960 to 1989 we consider various explanations for this clear shift first we suggest that financial deepening has a positive effect on growth if not done to excess rapid and excessive deepening as manifested in a credit boom can be problematic even in the most developed markets because it can both weaken the banking system and bring inflationary pressures we test this hypothesis by looking at the finance growth nexus among countries that have or have not experienced financial sector crises we find that once crisis episodes are removed the finance growth relationship remains intact its weakening over time thus seems to be a result of an increased incidence of crises in later years our second and related hypothesis is that the widespread liberalization of financial markets that occurred in the late 1980s and early 1990s made financial deepening less effective this is reminiscent of robert lucas s 1975 critique of econometric policy evaluation advanced three decades ago policies that have promoted and or forced increases in financial depth over the past two decades may have altered the basic structural relationship between finance and growth this could occur if the observed benefits of financial deepening led many countries to liberalize before the associated legal and regulatory institutions were sufficiently well developed as a consequence the impact of financial deepening on growth would become smaller our evidence does not indicate that recent liberalizations are responsible for the breakdown of the finance growth link however there may be an indirect link as premature financial development can lead to financial crises that have real effects third we examine the role of global equity markets that have grown in importance and prominence in the years over which the finance growth relationship disappeared however we do not find any evidence to suggest that equity market growth has substituted for the role of credit markets and banks in particular

distribution properties of latin american black market exchange rates abstract this paper conducts a statistical analysis of the distribution properties of black market exchange rate changes for 12 latin american currencies the infinite variance stable law hypothesis is tested using a regression type technique to estimate the parameters of the stable paretian distribution strong evidence is found supporting this hypothesis a separate analysis of extreme observations using a robust statistical procedure further supports these findings

ricardian equivalence in the presence of capital market imperfections abstract it is a common claim that ricardian equivalence fails if capital markets are imperfect the validity of this claim is examined for the case of informationally imperfect capital markets we present three alternative models of adverse selection and analyze the effects of debt finance in these models it is shown that a debt financed tax cut can lead to pareto improvement in some cases in the theoretically most preferable model however ricardian equivalence survives in spite of genuine imperfections in the capital market the results point to the importance of specifying the exact nature of imperfection

towards an accounting view on money banking and the macroeconomy history empirics theory in this paper three views are considered which are traditionally associated with money cranks and brave heretics the first is that the credit nature of money has macroeconomic significance the second is that financial development can be bad for economic growth the third is that macroeconomic models need to be explicitly monetary macroeconomic models it is argued that in each of these three areas there has been a recent shift in mainstream economic opinion this suggests new opportunities for meaningful debate between heterodox and orthodox schools on money and finance it is further argued following skaggs 2003 that a common meeting ground could be an accounting view of economics this is a mode of macroeconomic analysis which explicitly uses accounting definitions identities that credit is also debt or that flows of a variable affect the stock of that variable or accounting methods e g decomposing different kinds of liabilities or linking flows of liquidity to flows of transactions to structure and direct the analysis the accounting view is highly pluralist yet clearly defined i discuss its applications to each of the three views

quantitative modelling of the eur chf exchange rate during the target zone regime of september 2011 to january 2015 krugman 1991 s target zone model for exchange rate dynamics has become the reference of a large part of this literature despite its simplicity and elegance empirical evidence has been lacking not least because it is difficult to capture the predicted non linear relationship between the observable exchange rate and the non observable fundamental value this is why we propose a different approach by inverting locally the relation between exchange rate and fundamental value we derive analytical expressions for the conditional volatility and the probability density as a function of the exchange rate this allows us to examine krugman s prediction directly from historical data and furthermore enables us to test the smooth pasting condition which is intimately related to the no arbitrage condition concretely we study the performance of the euro swiss franc exchange rate in the extraordinary period from september 6 2011 to january 15 2015 when the swiss national bank enforced a minimum exchange rate of 1 20 swiss francs per euro we show that the data are well explained by the theory and conclude that krugman s target zone model holds after all but apparently only under extreme and sustained pressure that pushes continuously the exchange rate very close to the boundary of the target zone

bohn s test of fiscal sustainability of the american state governments the dramatic fall in state revenues during the great recession and the resultant large budget deficits accentuated concerns about state fiscal sustainability i employ a model based approach proposed by bohn 1998 to test for sustainability in this approach a positive and significant reaction of the ratio of primary surplus ratio s to lagged debt constitutes a sufficient condition for sustainability based on a panel of 48 contiguous states 1961 2008 and several model specifications i find robust evidence in favor of sustainability further analysis suggests that the adjustment of the components of s to debt is asymmetric with the revenue side bearing a heavier burden than the spending side the response of s is also found to be asymmetric with respect to the level of debt finally the magnitude of the response is larger in states with a higher degree of fiscal stringency in general and own revenue and no deficit carryover provisions in particular

fixed versus flexible exchange rates and measurement of exchange rate instability comment this paper comments on brodsky 1984 in which he refers to my november 1981 article the paper reiterates the point that the standard deviation cannot be used to draw statistical inferences when the underlying distribution is non normal stable paretian in such a case both the scale and characteristic exponent have to be considered

emerging markets and heavy tails abstract emerging countries are held to be subject to more frequent and more pronounced external and internal shocks than their developed counter parts this suggests that key variables pertaining to their markets including their exchange rates will be marked by greater likelihood of extreme observations and large fluctuations we focus on the hypothesis that compared to developed country exchange rates emerging country exchange rates will be more pronouncedly heavy tailed we find support for the hypothesis using recently proposed robust tail index estimation methods which in particular perform well under heavy tailed dependent garch processes that are often used for modeling exchange rates according to the estimation results reported in the paper variances may be infinite for several emerging country exchange rates tail index values p 2 6 2 8 appear to be at the dividing boundary between the two sets of countries while the moments of order p 2 6 2 8 are finite for most of the developed country exchange rates they may be or are infinite for most of the emerging country exchange rates we also study the impact of the on going financial and economic crisis and find that heavy tailedness properties of most exchange rates did not change significantly with the onset of the crisis at the same time some foreign exchange markets have experienced structural changes in their heavy tailedness properties during the crisis

schumpeter meeting keynes a policy friendly model of endogenous growth and business cycles this paper studies an agent based model that bridges keynesian theories of demandgeneration and schumpeterian theories of technology fueled economic growth we employ the model to investigate the properties of macroeconomic dynamics and the impact of public polices on supply demand and the fundamentals of the economy we find profound complementarities between factors influencing aggregate demand and drivers of technological change that affect both short run fluctuations and longterm growth patterns from a normative point of view simulations show a corresponding complementarity between keynesian and schumpeterian policies in sustaining long run growth paths characterized by milder fluctuations and relatively lower unemployment levels the matching or mismatching between innovative exploration of new technologies and the conditions of demand generation appear to suggest the presence of two distinct regimes of growth or absence thereof characterized by different short run fluctuations and unemployment levels

borrowing to defend the exchange rate and the timing and magnitude of speculative attacks abstract the paper analyses the implications for the timing and magnitude of a speculative attack on a fixed exchange rate of government borrowing to increase the stock of international reserves it is shown that such borrowing reduces the likelihood of an early collapse and increases the likelihood of an eventual collapse the magnitude of the speculative attack also increases

a tail index tour across foreign exchange rate regimes in turkey this article uses daily foreign exchange data in the usd trl foreign exchange market to test for structural breaks due to exchange rate regime switches the analysis focus on extreme movements of exchange rate returns across different regimes using tail index indicators sequential and rolling tests developed by quintos et al 2001 are used to identify the dates of breaks in the turkish exchange rate for the period 28 january 1980 to 11 october 2004 and for the sub periods which cover the fixed exchange rate regime from 28 january 1980 to 22 february 2001 and the flexible exchange rate regime from 23 february 2001 to 11 october 2004 compelling evidence for breaks in the tail index is found not only across but also within different exchange rate regimes especially within the fixed regime moreover breakpoint dates are clustered right before the crisis in 2001 this makes the tail index indicator a fairly good candidate for a variable to be used in early warning systems for currency crises

statistical distributions and the identification of currency crises abstract we use extreme value theory to identify periods of currency crisis for a broad cross section of asian european and latin american countries we argue that our methodology improves upon the more conventional methodology for defining currency crises because fewer parametric assumptions need to be satisfied we compare the incidence of currency crises using the conventional method with the incidence obtained using our method we conclude that identifying currency crises using extreme value theory is a good alternative to the conventional method

long term asset tail risks in developed and emerging markets a power law typically governs the tail decay of financial returns but the constancy of the so called tail index which dictates the tail decay remains relatively unexplored we study the finite sample properties of some recently proposed endogenous tests for structural change in the tail index given that the finite sample critical values strongly depend on the tail parameters of the return distribution we propose a bootstrap based version of the structural change test our empirical application spans developed and emerging financial asset returns somewhat surprisingly emerging stock market tails are not more inclined to structural change than their developed counterparts emerging currency tails on the contrary do exhibit structural shifts in contrast to developed currencies our results suggest that extreme value theory evt applications in hedging tail risks can assume stationary tail behavior over long time spans provided one considers portfolios that solely consist of stocks or bonds

how the european central bank decided its early monetary policy the main goal of this paper is to detect the mechanisms that should rationally stimulate the decision making policies of the european central bank ecb this is carried out under the framework of theoretical principles of interest rate rules firstly we deduce a set of logically advisable guidelines for the strategy actually developed by this central bank then we contrast a wide set of hypotheses with reference to those variables the ecb takes into account on deciding its monetary policy with a flexible treatment regarding the number of months of advance or delay in the explanatory variables the results lead us to the conclusion that the ecb besides adopting a smooth strategy especially bears in mind the expected core inflation rate with a reaction coefficient adjusted to that initially proposed by taylor the economic growth rate though it has a significant positive coefficient matters relatively little and is backward looking finally we evaluate up to what point the behaviour of the ecb is a

robust tests of forward exchange market efficiency with empirical evidence from the 1920s summary this paper provides a robust statistical approach to testing the unbiasedness hypothesis in forward exchange market efficiency studies the methods we use allow us to work explicitly with levels rather than differenced data they are statistically robust to data distributions with heavy tails and they can be applied to data sets where the frequency of observation and the futures maturity do not coincide in addition our methods allow for stochastic trend non stationarity and general forms of serial dependence the methods are applied to daily data of spot exchange rates and forward exchange rates during the 1920s which marked the first episode of a broadly general floating exchange rate system the tail behaviour of the data is analysed using an adaptive data based method for estimating the tail slope of the density the results confirm the need for the use of robust regression methods we find cointegration between the forward rate and spot rate for the four currencies we consider the belgian and french francs the italian lira and the us dollar all measured against the british pound we find support for a stationary risk premium in the case of the belgian franc the italian lira and the us dollar and we find support for the simple market efficiency hypothesis where the forward rate is an unbiased predictor of the future spot rate and there is a zero mean risk premium in the case of the us dollar

margin exceedences for european stock index futures using extreme value theory abstract futures exchanges require a margin requirement that ensures their competitiveness and protects against default risk this paper applies extreme value theory in computing unconditional optimal margin levels for a selection of stock index futures traded on european exchanges the theoretical framework focuses explicitly on tail returns thereby properly accounting for large levels of risk in measuring prudent margin levels the paper finds that common margin requirements are sufficient for each contract with the exception of the norwegian obx index in providing equitable costs for traders in addition the paper shows the underestimation bias in margin levels that are calculated assuming normality differing margin requirements reflect the unconditional and conditional trading environments

optimal funding rules abstract the operation of automatic fiscal stabilisers may prevent interest rates from falling during times of recession while they may lower interest rates during recovery thereby exacerbating the private sector business cycle we demonstrate that the government funding authority may devise rules for debt issuance which minimise the variance of the government s overall funding requirement this is done by switching issuance between different debt instruments in such a way that interest and redemption payments counteract the cycle in the underlying funding requirement thereby removing any autocorrelation in the net funding requirement we illustrate the application of such a funding rule to the borrowing requirement of the united kingdom government this has the effect of smoothing out the borrowing requirement over the business cycle
