parametric recoverability of preferences revealed preference theory is brought to bear on the problem of recovering approximate parametric preferences from consistent and inconsistent consumer choices we propose measures of the incompati

contagion during the greek sovereign debt crisis abstract we examine the impact of news about greece and news about a greek bailout on bank stock prices in 2010 using data for 48 european banks we identify the twenty days with extreme returns on greek sovereign bonds and categorise the news events during those days into news about greece and news about the prospects of a greek bailout we find that except for greek banks news about greece does not lead to abnormal returns while news about a bailout does even for banks without any exposure to greece or other highly indebted euro countries this finding suggests that markets consider news about the bailout to be a signal of european governments willingness in general to use public funds to combat the financial crisis sovereign bond prices of portugal ireland and spain respond to both news about greece and news about a greek bailout

garp for kids on the development of rational choice behavior in this paper we examine the extent to which consumption choices by 7 and 11 year old children and college undergraduates satisfy the axioms of revealed preference we find that choices by even the 7 year olds are considerably more likely to obey revealed preference axioms than would be true if they were choosing randomly 11 year olds do better still while college students do no better than 11 year old children we also find that mathematical ability is not correlated with choosing rationally we argue that this evidence suggests that the ability to choose rationally is not innate but that it does develop quickly

sovereign bond market reactions to no bailout clauses and fiscal rules the swiss experience abstract we analyse the effects of a credible no bailout policy and stringent sub national fiscal rules on the risk premia of swiss sub national government bonds in the period from 1981 to 2007 in july 2003 the swiss supreme court decided that the canton of valais is not liable for municipal debt this landmark decision reduced cantonal risk premia by about 26 basis points and cut the link between cantonal risk premia and the financial situation of the municipalities that existed before the result demonstrates that a not fully credible no bailout commitment can entail high costs for the potential guarantor additionally strong and credible balanced budget rules reduce risk premia

non stationarities in financial time series the long range dependence and the igarch effects we give the theoretical basis of a possible explanation for two stylized facts observed in long log return series the long range dependence lrd in volatility and the integrated garch igarch both these effects can be explained theoretically if one assumes that the data are nonstationary

the money pump as a measure of revealed preference violations we introduce a measure of the severity of violations of the revealed preference axioms the money pump index mpi the mpi is the amount of money one can extract from a consumer who violates the axioms it is also a statistical test for the hypothesis that a consumer is rational when behavior is observed with error we present an application using a panel data set of food expenditures the data exhibit many violations of the axioms mostly the mpi for these violations is small the mpi indicates that the hypothesis of consumer rationality cannot be rejected

eliciting welfare preferences from behavioural data sets an individual displays various preference orderings in different payoff irrelevant circumstances it is assumed that the variation in the observed preference orderings is the outcome of some cognitive process that distorts the underlying preferences of the individual we introduce a framework for eliciting the individual s underlying preferences in such cases and then demonstrate it for two cognitive processes satisficing and small assessment errors

what explains long memory in futures price volatility long memory in futures price volatility is a well documented stylized fact with implications for market efficiency risk management forecasting and option pricing bias the implications of long memory differ however based on whether it is of a fractional or of a stochastic type the aims of this article are to determine in the case of agricultural commodity futures data which type better describes price volatility and also to evaluate several competing explanations for findings of long memory the evidence presented here finds little support for three out of four potential explanations namely excessive noise in the volatility measure bias in the long memory estimator and understated ses of the long memory parameter for the data considered price volatility appears to be most likely generated by a nonfractional long memory process such as a stochastic break or stochastic unit root

does direct democracy reduce the size of government new evidence from historical data 1890 2000 using historical data for all swiss cantons from 1890 to 2000 we estimate the causal effect of direct democracy on government spending the main innovation in this paper is that we use fixed effects to control for unobserved heterogeneity and instrumental variables to address the potential endogeneity of institutions we find that the budget referendum and lower costs to launch a voter initiative are effective tools in reducing canton level spending however we find no evidence that the budget referendum results in more decentralized government or a larger local government our instrumental variable estimates suggest that a mandatory budget referendum reduces the size of canton spending between 13 and 19 percent a 1 percent lower signature requirement for the initiative reduces canton spending by up to 2 percent

nonstationarities in stock returns the paper outlines a methodology for analyzing daily stock returns that relinquishes the assumption of global stationarity giving up this common working hypothesis reflects our belief that fundamental features of the financial markets are continuously and significantly changing our approach approximates the nonstationary data locally by stationary models the methodology is applied to the s p 500 series of returns covering a period of over seventy years of market activity we find most of the dynamics of this time series to be concentrated in shifts of the unconditional variance the forecasts based on our nonstationary unconditional modeling were found to be superior to those obtained in a stationary long memory framework and to those based on a stationary garch 1 1 data generating process

on testing the utility hypothesis in order to be able to conduct a test of the core utility hypothesis that is not confounded with tests of subsidiary hypotheses that economic agents all have the same preferences and that their preferences are weakly separable it is necessary to use data that are disaggregated and complete in order to carry out a utility hypothesis test with complete data revealed preference theory must first be extended the generalised axiom of revealed preference is extended to include labour supply and portfolio choice then a complete disaggregated data set is used to test the utility hypothesis and two preference separability hypotheses

evidence on the extent and potential sources of long memory in u s treasury security returns and yields unlike equity returns many fixed income return measures appear to display long memory we show that the extent of long memory differs strongly for gross and excess holding period returns on u s treasury securities granger and others have argued that long memory may only reflect infrequent structural breaks we explore the impact of structural instability on tests for long memory and find only weak indications that it lies behind the long memory in our return series the evidence of long memory remains strong for yield and term premia series even after accounting for a series of potential underlying structural changes

modeling long memory and structural breaks in conditional variances an adaptive figarch approach this paper introduces a new long memory volatility process denoted by adaptive figarch or a figarch which is designed to account for both long memory and structural change in the conditional variance process structural change is modeled by allowing the intercept to follow a slowly varying function speci ed by gallant 1984 s exible functional form a monte carlo study nds that the a figarch model outperforms the standard figarch model when structural change is present and performs at least as well in the absence of structural instability an empirical application to stock market volatility is also included to illustrate the usefulness of the technique

vertical debt spillovers in emu countries abstract this article examines the extent to which subnational governments may drive sovereign risk premiums is subnational fiscal policy affecting the interest rates on central government bonds furthermore we focus on a number of causal mechanisms that may mitigate or reinforce these upstream vertical spillovers i e the presence of bailout expectations and subnational borrowing autonomy our findings indicate that debt accumulation by subnational governments sng spills over onto sovereign risk premiums when the restrictions on sng borrowing are weak and when investors believe that subsovereign debts are backed by the center the results suggest that spillovers may be reduced through a proper design of a country s fiscal and institutional framework countries should either bolster the sovereignty of subnational governments by increasing sng fiscal autonomy or tightening up sng borrowing constraints

what drives provincial canada yield spreads although recent research has led to a deeper understanding of the factors determining yields on long term canada bonds there has been little corresponding work on provincial bonds this is despite the fact that unlike the us state bond market provincial debt represents a significant part of the canadian bond market provincial and state debt are examples of sub national debt which are backed by taxing powers similar to that of the national government but without control of the money supply which leaves them open to the possibility of default or payment rescheduling this in turn makes them similar to corporate debt by using a carefully constructed new data set we establish two important results first provincial fiscal positions debt and deficits are an important factor in determining yield spreads between provincial and canada bonds second we show that provincial bonds are a substitute for corporate debt in that during recessionary flights to quality their yields react similar to those on corporate bonds

budget referendums and government spending evidence from swiss cantons vortrag im forschungsseminar der wirtschaftswissenschaftlichen fakultat der universitat basel schweiz am 20 november 2000

fiscal news state budget rules and tax exempt bond yields abstract this paper investigates how state fiscal institutions such as balanced budget rules and restrictions on state debt issuance mediate the bond market reaction to state fiscal news we analyze data on the yields of bonds issued by different states as reported in the chubb relative value survey along with data on state budget forecasts for the period 1988 1998 we find that unexpected deficits are correlated with higher state bond yields this effect is smaller for states with tight antideficit rules than for states without these fiscal rules unexpected deficits have a particularly large effect in raising bond yields of states with tax limits these results suggest that bond market participants view fiscal institutions as relevant in assessing the risk characteristics of tax exempt bonds and that the economic significance of these institutions depends on the state s economic and fiscal circumstances

on government centralization and fiscal referendums abstract several authors have argued that a centralization of fiscal powers in a federation is less likely to occur if citizens have to approve a change in the assignments of responsibilities by a popular referendum this outcome may be due to the fact that logrolling is more difficult under direct than under representative democracy it may also be caused by citizens fear that a centralization of fiscal authority facilitates the extraction of rents by the government or the legislature in this paper we test the hypothesis that centralization is less likely under referendum decision making in the unique institutional setting of switzerland using a panel of swiss cantons from 1980 to 1998 the empirical analysis provides evidence that referendums induce less centralization of fiscal activities

fiscal space and sovereign risk pricing in a currency union abstract we examine how membership in a currency union affects public debt sustainability and market assessments of default risk in eurozone countries we argue that there exist offsetting effects expectations of bailouts tend to make a given level of debt more sustainable lowering bond yields and cds rates but constraints on the use of monetary policy would tend to have the opposite effect pushing rates up especially as room for fiscal maneuver gets exhausted we develop a formal concept of fiscal space which takes account of the notion of fiscal fatigue under which there are limits to the government s ability to raise the primary surplus in response to higher debt and apply it to the eurozone countries investigating in particular how currency union membership affects cds and bond rates during both quiet and turbulent times for a given amount of fiscal space we find that in quiet times cds and bond rates for eurozone members were below what would be expected given their fiscal space a bonus from currency union membership but when the crisis erupted cds and bond yields rose more sharply for eurozone members than would be predicted based on their available fiscal space our interpretation is that sovereign bailouts did not occur with the hoped for alacrity in euro crisis countries generating sharper penalties for sovereigns that belong to a currency union

the dynamics of stock index and stock index futures returns in rational efficiently functioning markets the returns on stock index and stock index futures contracts should be perfectly contemporaneously correlated this study investigates the time series properties of 5 minute intraday returns of stock index and stock index futures contracts and finds that sp however the effect is not completely unidirectional with lagged stock index returns having a mild positive predictive impact on futures returns

how do official bailouts affect the risk of investing in emerging markets we analyze the effects of bailout expectations on sovereign bond spreads in emerging markets the non bailout of russia in august 1998 is interpreted as an event that decreased the perceived probability of future crisis lending to emerging markets if official rescues are expected to mitigate the losses of investors in the event of a crisis such an event should raise the cross country dispersion of spreads because investors pay more attention to differences in risk characteristics across countries we find strong evidence for such an effect this is consistent with the existence of investor moral hazard at least prior to 1998

what drives spreads in the euro area government bond market spreads between euro area government bond yields are related to short term interest rates which are in turn related to market liquidity to cyclical conditions and to investors incentives to take risk in theory lower interest rates are associated with lower degrees of risk aversion and smaller government bond spreads empirically the eurosystem s short term interest rates are positively related to those spreads which our econometric model finds to include significant and policy relevant default risk and liquidity risk components simone manganelli and guido wolswijk

measuring rationality with the minimum cost of revealed preference violations abstract we introduce a new measure of how close a set of choices is to satisfying the observable implications of rationality and apply it to a large balanced panel of household level consumption data this new measure the minimum cost index is the minimum cost of breaking all revealed preference cycles found in choices from budget sets unlike existing measures of rationality it responds to both the number and severity of revealed preference violations

how demanding is the revealed preference approach to demand a well known problem with revealed preference methods is that when data are found to satisfy their restrictions it is hard to know whether this should be viewed as a triumph for economic theory or a warning that these conditions are so undemanding that almost anything goes this paper allows researchers to make this distinction our approach uses an axiomatic characterization of a measure of predictive success due to selten 1991 we illustrate the idea using a panel dataset the results show that this approach can lead us to radically reassess our view of the empirical performance of economic theory

sovereign risk premia the link between fiscal rules and stability culture abstract there is a growing empirical literature studying whether permanent constraints on fiscal policy such as fiscal rules reduce sovereign risk premia nevertheless it remains an open question whether these rules are effective genuinely or just because they mirror fiscal preferences of politicians and voters in our analysis of european bond spreads before the financial crisis we shed light on this issue by employing several types of stability preference related proxies these proxies refer to a country s past stability performance government characteristics and survey results related to general trust we find evidence that these preference indicators affect sovereign bond spreads and dampen the measurable impact of fiscal rules yet the interaction of stability preferences and rules points to a particular potential of fiscal rules to restore market confidence in countries with a historical lack of stability culture

exchange rate dynamics in south africa abstractthe structure of the nominal exchange rates in south africa is examined by using fractional integration we investigate the levels and the volatilities against the us dollar the british po

basis convergence and long memory in volatility when dynamic hedging with futures abstractwhen market returns follow a long memory volatility process standard approaches to estimating dynamic minimum variance hedge ratios mvhrs are misspecified simulation results and an application to the s p 500 index document the magnitude of the misspecification that results from failure to account for basis convergence and long memory in volatility these results have important implications for the estimation of mvhrs in the s p 500 example and other markets as well

testing data for consistency with revealed preference the author develops a method of hypothesis testing for revealed preference tests this method is particularly well suited to tests of commonality of tastes or tests of preference stability he devises a metric based on an estimate of the fraction of expenditure wasted in maximizing utility if all consumers in the sample share the same utility function this metric increases in size with increases in the proportion of observations having different tastes and with increasing differences in tastes the author proposes bootstrap methods for estimating the distribution of the test statistic copyright 1995 by mit press

long memory and structural changes in the forward discount an empirical investigation abstract we analyze the evidence for long memory and structural changes in the five g7 countries forward discount we establish evidence for long memory by estimating the long memory parameter without allowing for structural breaks we also document evidence for multiple structural breaks in the mean of the forward discount we then adjust for structural changes in the forward discount rate and re estimate the long memory parameter after removing the breaks we still find evidence of stationary long memory in each country s forward discount

estimation methods for stochastic volatility models a survey abstract although stochastic volatility sv models have an intuitive appeal their empirical application has been limited mainly due to difficulties involved in their estimation the main problem is that the likelihood function is hard to evaluate however recently several new estimation methods have been introduced and the literature on sv models has grown substantially in this article we review this literature we describe the main estimators of the parameters and the underlying volatilities focusing on their advantages and limitations both from the theoretical and empirical point of view we complete the survey with an application of the most important procedures to the s p 500 stock price index

understanding the soft budget constraint we propose a clarification of the notion of a soft budget constraint a concept widely used in the analysis of socialist transitional and market economies our interpretation is broad enough to embrace most existing approaches to soft budget constraint phenomena and provides a classification of their causes and consequences in light of this interpretation we then review the theoretical literature on the subject and compare it with those on other dynamic commitment problems in economics

portfolio optimization in the presence of dependent financial returns with long memory a copula based approach abstract in this paper we seek to examine the effect of the presence of long memory on the dependence structure between financial returns and on portfolio optimization first we focus on the dependence structure using copulas to select the best copula in addition to the goodness of fit tests we employ a graphical method based on visual comparison of the fitted copula density and the smoothed copula density estimated by wavelets moreover we check the stability of the copula parameter the empirical results show that the long memory affects the dependence structure second we analyze the impact of this dependence structure on the optimal portfolio we propose a new approach based on minimizing the conditional value at risk and assuming that the dependence structure is modeled by the copula parameter the empirical results show that our approach outperforms the traditional minimizing variance approach where the dependence structure is represented by the linear correlation coefficient

yield spreads on emu government bonds government bond spreads we provide evidence that the movements in yield differentials between euro zone government bonds explained by changes in international risk factors as measured by banking and corporate risk premiums in the united states are more pronounced for bonds issued by italy and spain liquidity factors play a smaller role so policies meant to increase financial market efficiency do not appear sufficient to deliver a seamless bond market in the euro area the risk of default is a small but important component of yield differentials movements which signal market perceptions of fiscal vulnerability impose market discipline on national fiscal policies and may be reduced only by further convergence in debt ratios lorenzo codogno carlo favero and alessandro missale

a theory of anticipated utility abstract a new theory of cardinal utility with an associated set of axioms is presented it is a generalization of the von neumann morgenstern expected utility theory which permits the analysis of phenomena associated with the distortion of subjective probability

network structure and n dependence in agent based herding models abstract we derive microscopic foundations for a well known probabilistic herding model in the agent based finance literature while the model is quite robust with respect to behavioral heterogeneity the network structure describing the very feasibility of agent interaction turns out to have a crucial and non trivial impact on the macroscopic properties of the model

do credit markets discipline sovereign borrowers evidence from u s states the degree to which credit markets discipline sovereign borrowers is investigated by estimating the supply curve for debt faced by u s states the results generally support an optimistic view of the market discipline hypothesis with credit markets providing incentives for sovereign borrowers to restrain borrowing while the risk premium on bond yields is estimated to increase only gradually at low levels of debt this effect appears to become much larger as debt rises there is also some evidence that credit markets may withhold access to credit at very high levels of debt copyright 1995 by ohio state university press

level shifts and the illusion of long memory in economic time series when applied to time series processes containing occasional level shifts the log periodogram gph estimator often erroneously finds long memory for a stationary short memory process with a slowly varying level i show that the gph estimator is substantially biased and derive an approximation to this bias the asymptotic bias lies on the 0 1 interval and its exact value depends on the ratio of the expected number of level shifts to a user defined bandwidth parameter using this result i formulate the modified gph estimator which has a markedly lower bias i illustrate this new estimator via applications to soybean prices and stock market volatility

memory and infrequent breaks abstract we study how processes with infrequent regime switching may generate a long memory effect in the autocorrelation function in such a case the use of a strong fractional i d model for economic or financial analysis may lead to spurious results

equilibrium analysis of portfolio insurance a martingale approach is used to characterize general equilibrium in the presence of portfolio insurance insurers sell to noninsurers in bad states and general equilibrium requires that the risk premium rises to induce noninsurers to increase their holdings we show that portfolio insurance increases price volatility causes mean reversion in asset returns raises the sharpe ratio and volatility in bad states and causes volatility to be correlated with volume we also explain why out of the money sp that is the demand for an absolute level of price protection is equivalent to a demand for put options 1 we show that a similar argument can be used in a

a measure of rationality and welfare evidence showing that individual behavior often deviates from the classical principle of preference maximization has raised at least two important questions 1 how serious are the deviations 2 what is the best way to analyze choice behavior in order to extract information for the purpose of welfare analysis this paper addresses these questions by proposing a new way to identify the preference relation that is closest in terms of welfare loss to the revealed choice

sovereign bond yield spreads a time varying coefficient approach abstract we study the determinants of sovereign bond yield spreads across 10 emu countries between q1 1999 and q1 2010 we apply a semiparametric time varying coefficient model to identify to what extent an observed change in the yield spread is due to a shift in macroeconomic fundamentals or due to altering risk pricing we find that at the beginning of emu the government debt level and the general investors risk aversion had a significant impact on interest differentials in the subsequent years however financial markets paid less attention to the fiscal position of a country and the safe haven status of germany diminished in importance by the end of 2006 two years before the fall of lehman brothers financial markets began to grant germany safe haven status again one year later when financial turmoil began the market reaction to fiscal loosening increased considerably the altering in risk pricing over time period confirms the need of time varying coefficient models in this context

the nature of the relationship between international tourism and international trade the case of german imports of spanish wine this article deals with the relationship between international trade and tourism we focus on the effect that german tourism to spain has on german imports of spanish wine due to the different stochastic properties of the series under analysis which display different orders of integration a methodology is used based on long memory regression models where tourism is supposed to be exogenous the period covered is january 1998 to november 2004 the results show that tourism has an effect on wine imports that lasts between 2 and 9 months disaggregating the imports across the different types of wine it is observed that only for red wines from navarra penedus and valdepenas and to a certain extent for sparkling wine tourism produces an effect on future import demand from a policy making perspective our results imply that the impact of tourism on the host economy is not only direct and short term but also oblique and delayed thus reinforcing the case for tourism as a means for economic development

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

long memory and structural breaks in the returns and volatility of gold evidence from turkey this article examines the long memory properties and structural breaks in spot and futures gold returns and volatility in turkey the data cover the period from 2008 through 2013 in which gold prices hit an all time high arfima figarch model provides evidence of dual long memory in spot series and a lack of long memory property in futures returns anti persistence in spot returns is indicative of an overreaction of gold prices to new information thus disconfirming the weak form of market efficiency the findings further provide evidence of one structural break which is associated with correction in the gold prices during the post global financial crisis the analyses suggest that the long memory is true not spurious this implies that long memory is a feature of the data instead of an outcome of structural changes

nonparametric tests of utility maximization and weak separability for consumption leisure and money some of the most fundamental assumptions of economics are utility maximization and weak separability of the arguments in the represen tative consumer s utility function this paper contains results from nonparametric tests of these assumptions about consumer behavior the authors find that quarterly per capita data on consumption goods le isure and monetary assets are consistent with utility maximization further consumption goods and leisure meet necessary and sufficient conditions for weak separability additionally one grouping of relat ively liquid monetary assets meets the necessary conditions for weak separability they also test and find no evidence of homothetic prefe rences copyright 1987 by mit press

testing for autocorrelation using a modified box pierce q test this article investigates the finite sample performance of a modified box pierce q statistic q for testing that financial time series are uncorrelated without assuming statistical independence the finite sample rejection probabilities of the q test under the null and its power are examined in experiments using time series generated by an ma 1 process where the errors are generated by a garch 1 1 model and by a long memory stochastic volatility model the tests are applied to daily currency returns

consistency and heterogeneity of individual behavior under uncertainty by using graphical representations of simple portfolio choice problems we generate a very rich dataset to study behavior under uncertainty at the level of the individual subject we test the data for consistency with the maximization hypothesis and we estimate preferences using a two parameter utility function based on faruk gul 1991 this specification provides a good interpretation of the data at the individual level and can account for the highly heterogeneous behaviors observed in the laboratory the parameter estimates jointly describe attitudes toward risk and allow us to characterize the distribution of risk preferences in the population

forecasting volatility and volume in the tokyo stock market long memory fractality and regime switching abstract we investigate the predictability of both volatility and volume for a large sample of japanese stocks the particular emphasis of this paper is on assessing the performance of long memory time series models in comparison to their short memory counterparts since long memory models should have a particular advantage over long forecasting horizons we consider predictions of up to 100 days ahead in most respects the long memory models arfima figarch and the recently introduced multifractal model dominate over garch and arma models however while figarch and arfima also have quite a number of cases with dramatic failures of their forecasts the multifractal model does not suffer from this shortcoming and its performance practically always improves upon the naive forecast provided by historical volatility as a somewhat surprising result we also find that for figarch and arfima models pooled estimates i e averages of parameter estimates from a sample of time series give much better results than individually estimated models

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

real and spurious long memory properties of stock market data we test for the presence of long memory in daily stock returns and their squares using a robust semiparametric procedure of lobato and robinson spurious results can be produced by nonstationarity and aggregation we address these problems by analyzing subperiods of returns and using individual stocks the test results show no evidence of long memory in the returns by contrast there is strong evidence in the squared returns

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

the impact of corporate and personal income taxes on the location of firms and on employment some panel evidence for the swiss cantons abstract the impact of corporate income taxes on location decisions of firms is widely debated in the tax competition literature tax rate differences across jurisdictions may lead to distortions of firms investment decisions empirical evidence on tax induced relocation and subsequent economic development in the us and europe is still inconclusive much the same applies to switzerland while there is some evidence on personal income tax competition between swiss cantons evidence on the impact of intercantonal corporate income tax differences on the location of business within switzerland is missing in this paper we present econometric evidence on the influence of corporate and personal income taxes on the regional distribution of firms in 1981 and 1991 and on cantonal employment using a panel data set of the 26 swiss cantons from 1985 to 1997 the results show that corporate and personal income taxes deter firms to locate in a canton and subsequently reduce cantonal employment

long range dependence in daily stock volatilities recent empirical studies show that the squares of high frequency stock returns are long range dependent and can be modeled as fractionally integrated processes using for example long memory stochastic volatility models are such long range dependencies common among stocks are they caused by the same sources of variation in this article we classify daily stock returns of standard and poor 500 companies on the basis of a company s size and its business or industrial sector and estimate the strength of long range dependence in the stock volatilities using two different methods almost all of the companies analyzed exhibit strong persistence in volatility we then use a canonical correlation method to identify common long range dependent components in groups of companies finding strong evidence in support of common persistence in volatility finally we use a chi squared test to study the effects of company size and sector on the number of common long range dependent volatility components detected in g
