sign and volatility switching arch models theory and applications to international stock markets summary this paper develops two conditionally heteroscedastic models which allow an asymmetric reaction of the conditional volatility to the arrival of news such a reaction is induced by both the sign of past shocks and the size of past unexpected volatility the proposed models are shown to converge in distribution to

extreme return connectedness and its determinants between clean green and dirty energy investments abstract previous studies point to the time variation and asymmetry in the relationship between clean energy stocks and crude oil markets but there is a lack of evidence on the return spillovers between clean green assets and dirty energy assets crude oil and energy etf in lower and upper quantiles and their potential drivers to address these gaps we apply quantile based estimators to measure return connectedness at left and right tails of the conditional distribution of return shocks we find that the average level of return connectedness estimated at the mean median is 29 whereas it reaches 65 when estimated at the left and right tails thus return connectedness across clean energy stocks green bonds crude oil and energy etf is larger at both left and right tails implying that the unsuitability of applying mean based connectedness measures furthermore we show that return connectedness measures vary with time but they are less volatile in the tails notably return connectedness differs between periods of extreme negative returns and periods of extreme negative returns suggesting an asymmetric behaviour an analysis of the drivers of the return connectedness shows the importance of macroeconomic conditions especially at middle and lower quantiles us dollar has a positive impact in all cases whereas the crude oil market uncertainty intensifies the return spillovers at the lower quantile

the economic organization of legislatures and how it affects congressional voting congress confronts two major organizational problems that affect the behavior of legislators party leaders and groups doing business with congressional committees the costly nature of monitoring and the absence of explicit mechanisms for upholding agreements the problem of monitoring implies that party leaders will have a difficult time influencing decisions made in decision making arenas where the actions of legislators are less visible as in congressional committees while legislators can evade leadership monitoring of their actions within committees once an issue leaves a committee the costs of monitoring decline and leadership influence increases the absence of mechanisms for assuring that legislators keep their bargains means that groups will place an emphasis on dealing with reliable legislators those who can be counted upon to uphold their end of a bargain thus party leaders are more effective in influencing floor voting because of their better ability to monitor legislator behavior however obligations to important interest groups will be more immune to leadership influence because of the incentives for committee members to adhere to their bargains

stock returns implied volatility innovations and the asymmetric volatility phenomenon we study the dynamic relation between daily stock retums and daily innovations in optionderived implied volatilities by simultaneously analyzing innovations in index and firmlevel implied volatilities we distinguish between innovations in systematic and idiosyncratic volatility in an effort to better understand the asymmetric volatility phenomenon our results indicate that the relation between stock retums and innovations in systematic volatility idiosyncratic volatility is substantially negative near zero these results suggest that asymmetric volatility is primarily attributed to systematic market wide factors rather than aggregated firm level effects we also present evidence that supports our assumption that innovations in implied volatility are good proxies for innovations in expected stocic volatility

detecting multiple breaks in financial market volatility dynamics the paper evaluates the performance of several recently proposed tests for structural breaks in the conditional variance dynamics of asset returns the tests apply to the class of arch and sv type processes as well as data driven volatility estimators using high frequency data in addition to testing for the presence of breaks the statistics identify the number and location of multiple breaks we study the size and power of the new tests for detecting breaks in the conditional variance under various realistic univariate heteroscedastic models change point hypotheses and sampling schemes the paper concludes with an empirical analysis using data from the stock and fx markets for which we find multiple breaks associated with the asian and russian financial crises these events resulted in changes in the dynamics of volatility of asset returns in the samples prior and post the breaks copyright 2002 john wiley sons ltd

causality between public expenditure and national income this paper deploys the granger method to determine the directions and patterns of causality between national income and total as well as various components of public expenditure empirical results based on the data for india 1950 81 suggest that while at the disaggregate level the causal process is rather diverse it is essentially feed back type at the aggregate level it neither confirms the wagnerian income public expenditure nor the keynesian public expenditure national income view the paper recommends that two variables be treated as jointly dependent in both the public finance and macroeconometric studies

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

structural breaks and garch models of exchange rate volatility we investigate the empirical relevance of structural breaks for garch models of exchange rate volatility using both in sample and out of sample tests we find significant evidence of structural breaks in the unconditional variance of seven of eight us dollar exchange rate return series over the 1980 2005 period implying unstable garch processes for these exchange rates and garch 1 1 parameter estimates often vary substantially across the subsamples defined by the structural breaks we also find that it almost always pays to allow for structural breaks when forecasting exchange rate return volatility in real time combining forecasts from different models that accommodate structural breaks in volatility in various ways appears to offer a reliable method for improving volatility forecast accuracy given the uncertainty surrounding the timing and size of the structural breaks copyright 2008 john wiley sons ltd

large shocks in the volatility of the dow jones industrial average index 1928 2013 we determine the events that cause large shocks in volatility of the djia index over the period 1928 2013 using a new semi parametric test based on conditional heteroscedasticity models we find that these large shocks can be associated with particular events financial crashes elections wars monetary policies etc we show that some shocks are not identified as extraordinary movements by the investors due to their occurring during high volatility episodes especially the 1929 1934 1937 1938 and 2007 2011 periods

on the casual relationship between government expenditures and national income a research strategy is suggested that separates the issue of inference from the problems of prediction or of quantitative policy analysis of an empirical parametric model and illustrates a new methodology that enables this in a test for prima facie causality unlike the conventional parametric test the more powerful multiple rank f test is invariant to monotonic transformations of the variables and independent of the error distribution employing this test the wagnerian hypothesis supported by conventional parametric analysis is rejected and the conventional keynesian theory is accepted copyright 1990 by mit press

economic development institutional change and the political economy of agricultural protection an econometric study of belgium since the 19th century this empirical study uses 100 years of annual data on 11 agricultural commodities from belgium to measure the impact of structural changes coinciding with economic development and changes in political institutions on agricultural protection the analysis shows that changes in agricultural protection are caused by a combination of factors governments have increased protection and support to farmers when world market prices for their commodities fell and vice versa offsetting market effects on producer incomes other economic determinants were the share of the commodities in total consumer expenditures negative effect and in total output of the economy positive effect with belgium a small economy there was no impact of the trade position changes in political institutions have affected agricultural protection democratic reforms which induced a significant shift in the political balance towards agricultural interests such as the introduction of the one man one vote system led to an increase in agricultural protection the integration of belgian agricultural policies in the common agricultural policy in 1968 coincided with an increase in protection ceteris paribus both institutional factors related to changes in access to and information about the decision making at the eu level and structural changes in the agricultural and food economy may explain this effect

lag length selection and tests of granger causality between money and income one of the most widely accepred relationships in macroeconomics is the positive relationship between the rate of growth of the money supply and the rate of growth of income a diversity of opinion arises however with the attempt to identify a causal relationship between these variables while friedman and schwartz 1963 initiated the empirical investigation of money income causality sims 1972 made the most significant contribution to this literature with a practical application of the criterion developed by granger 1969 for identifying a causal relationship since the appearance of sims s approach and an alternative one advanced by sargent 1976 many researchers have applied these techniques to the investigation of the causal relationship between money and income l with two exceptions hsiao 1981 and mcmillin and fackler 1984 these researchers have arbitrarily chosen the lengths of their distributed lags the purpose of this paper is to test for granger causality between money and income this paper differs from previous work in that considerably more attention is focused on the effect of the lag specification on the test results in particular we investigate the extent to which rules of thumb arbitrary lag specifications and

modeling structural breaks in economic relationships using large shocks abstract this paper introduces a new model of structural breaks in the coefficients of economic relationships which allows them to be driven by large past economic shocks the breaks generated by these shocks can be taken to reflect stochastic changes in agents decisions or beliefs triggered by extraordinary economic events our model specifies that both the timing and size of breaks are stochastic the last property of it enables us to investigate qualitative effects that large shocks can have on economic relationships as an empirical application of our model the paper investigates the stability the oil economy relationship since the early sixties from the six large oil shocks identified by our data the paper shows that only the first oil shock at the end of 1973 has caused a major long term adverse effect on economic activity all the large oil price shocks that have happened since then did not have any significant negative effects on the slope of the oil economy relationship

structural breaks in volatility evidence for the oecd and non oecd real exchange rates abstract this paper attempts to determine whether or not nominal exchange rate regimes affect the volatility of bilateral and effective real exchange rates to that end we examine the real exchange rate behaviour for a set of oecd and non oecd countries during the 1960 2006 period therefore covering both the bretton woods system of fixed exchange rates and the adoption of generalised floating exchange rates from 1973 we make use of an econometric methodology based on the hansen s hansen b e 1997 approximate asymptotic p values for structural change tests journal of business and economic statistics 15 1 60 67 approximation to the p values of the supreme exponential and average statistics developed by andrews andrews d 1993 test for parameter instability and structural change with unknown change point econometrica 61 4 821 856 and andrews and ploberger andrews d ploberger w 1994 optimal tests when a nuisance parameter is present only under the alternative econometrica 62 6 1383 1414 this methodology allows us to obtain a profile of p values and to delimit periods of stability and instability in the variance of real exchange rates results suggest that there is clear evidence in favour of the non neutrality of nominal exchange rate regime regarding real exchange rate volatility for developed countries but not in the case of developing or emerging countries

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

the effects of logrolling on congressional voting the theoretical public choice literature suggests that vote trading is an important determinant of congressional voting behavior yet empirical voting models do not allow for vote trading these models recognize that observed ideology may influence legislative behavior but do not correct for unobserved ideology this study devises new tests for logrolling and ideology the empirical model controls for logroll agreements and unobserved ideological interest via the correlation of unobserved variables the results reflect the presence of vote trading coalitions on some votes but not on others the results cast doubt on the importance of personal ideological interests of legislators copyright 1992 by american economic association

the persistence in volatility of the us term premium 1970 1986 abstract this paper examines the persistence of the volatility of the risk premia for excess holding period returns of the term structure using a garch m model of the conditional variance the finding of a high degree of persistence cannot be sustained once allowance is made for a structural break in the unconditional variance caused by a change in the operation of us monetary policy during 1979 1982

the political economy of market based environmental policy the u s acid rain program the u s acid rain program enacted in 1990 gave valuable tradable sulfur dioxide emissions permits called allowances to electric utilities we examine the political economy of this allocation though no senate or house votes were ever taken hypothetical votes suggest that the actual allocation would have beaten plausible alternatives while rent seeking behavior is apparent statistical analysis of differences between actual and benchmark allocations indicates that the legislative process was more complex than simple models suggest the coalition of states that produced and burned high sulfur coal both failed to block acid rain legislation in 1990 and received fewer allowances than in plausible benchmark allocations some of these states may have received additional allowances to cover 1995 99 emissions by giving up allowances in later years and some major coal producing states seem to have focused on benefits for miners and on sustaining demand for high sulfur coal

the effects of congressional appropriation committee membership on the distribution of federal research funding to universities i introduction in 1994 members of the republican party pledged to seek legislation to impose term limits on members of congress this pledge stemmed from the popular belief that senior members of congress tend to promote personal interests or are more influenced by lobbying efforts that may not be representative of their constituents today term limits continue to be discussed but have not been enacted instead many members have focused their energies toward minimizing the time spent on any particular committee of congress believing that tenure on a committee is a more serious concern than simple tenure in congress implicit in these concerns is the issue whether as incumbent politicians plan to retire they will behave differently and if so whether tenure on a congressional committee exacerbates this behavior this article explores the role of membership on the appropriations committee on the distribution of federal research funding to universities specifically it explores whether funding is diverted to these universities because politicians use their position on a committee to promote personal or constituent interests previous research on shirking compares the voting records of politicians on certain issues with demographic and economic characteristics of the politicians constituents this article explores the issue of shirking differently i explore how membership on congressional appropriations committees affects the distribution of federal research funding to universities i look at two types of relationships between the members and the universities first i consider the relationship between members and the universities that are located in the members districts states in the case of senators second i examine the relationship between members and their undergraduate alma mater i use district representa tion to proxy favoritism that reflects a politician s constituents given that in most instances an alma mater affiliation is not the same as district representation i use alma mater affiliation to proxy favoritism that reflects the politician s personal interests federal research funding accounts for more than 60 of research funding received by research universities previous research has shown a positive impact of federal funding on research outcomes see adams and griliches 1998 arora and gambardella 1997 connolly 1997 payne and siow 2002 and payne 2001 except for payne and siow 2002 however these articles do not consider that political diversion of funds may promote or detract from research productivity as with any other federal program this article concentrates on the impact of membership on the house and senate appropriations committees because they wield the greatest power in the allocation of funding 1 using a panel data set spanning 26 years i explore how changes in the composition of the appropriations committees affects the distribution of research funding after controlling for the heterogeneity that exists across different universities the results suggest that both district representation and alma mater affiliation matter thus there is evidence of shirking for personal interests and evidence of members representing their constituents with respect to the representation of one s constituents the strongest results suggest that public universities benefit from representation on both the senate and house committees private universities however only benefit from representation in the senate with respect to alma mater affiliations the results suggest again that public universities benefit from representation on both the senate and house committees private universities also benefit from representation on both the senate and house committees the results also suggest that the tenure of the member on the committee matters as does whether the member is a part of the majority party in power in the congressional chamber

the budget process and the size of the budget the new congressional budget process provides members of congress with a new set of institutional mechanisms for making budget decisions this article addresses the question of whether or under what conditions rigid application of the new budget process modeled as first selection of the size of the budget and second its division produces smaller budgets than a piecemeal appropriations process in which the size of the budget is determined residually the theoretical result is that the new process sometimes results in relatively large budgets a testable implication of the theory is that given a choice of how stringently the budget process is to be employed members of congress jointly consider preferences and the expected outcomes under available institutional arrangements and select the arrangement usually a rule that yields the most favorable outcome empirical results from the budget process in the house from 1980 to 1983 are generally supportive of the theoretically derived hypothesis of rational choice of institutional arrangements

bureaucrats legislators and the size of government some recent theories have blamed the growth of government on budget maximizing bureaucrats who are assumedly capable of imposing their most preferred budget output combination on legislatures subject to cost and demand constraints however theoretical examination of the range of bargaining outcomes that might occur between bureau and legislature shows that budget maximizing behavior does not necessarily lead to super optimal levels of production nor do the suggested reforms of competition and privatization necessarily improve the situation in this bargaining model the central determinants of governmental growth are not budget maximizing bureaucrats but the legislature s decisions regarding mode of oversight and form of internal organization

property tax and inter municipal migration in canada a multivariate test of the tiebout hypothesis this paper tests the causal ordering between property taxes and inter municipal migration using both bivariate and multivariate methods empirical results based on annual data for post war canada 1940 84 support the tiebout tullock hypothesis which implies that differential local tax system and public services induce inter comunity migration inter alia local spending and taxation are not therefore fully capitalized in property values the bivariate tests based on the granger sims test and hsiao s procedure indicate an instantaneous bidirectional causality between property taxes and migration but the multivariate granger test supports only a unidirectional causality from property taxes to migration

the impact of tenure on the flow of federal benefits to smsa s the seniority system in congress insures that committee assignments and chairmanships are distributed on the basis of house members tenure this system supposedly means that congressional influence increases with the number of times a member of congress is reelected however research on the impact of tenure on the distribution of federal aid across states has not produced convincing proof that a positive relationship between tenure and aid exists crain and tollison 1977 undertook the first study of the impact of tenure and they concluded that tenure has a positive effect on the share of total federal aid going to states indeed crain and tollison found evidence of diminishing returns to additional years of house service however green and munley 1981 quickly disputed the crain tollison findings suggesting that after adjusting for state population which affects

testing wagner versus keynes using disaggregated public expenditure data for canada this paper attempts to test wagnerian versus keynesian hypotheses by examining the relationship between national income and total public expenditure as well as its various components for canada during the period 1950 1995 engle and granger s two step cointegration and error correction techniques are employed to test these two hypotheses the results of this study support both the hypotheses when tested with broader aggregate expenditure data i e total government current expenditure ce and total current expenditures on goods and services cegs although the results of this study do not support the existence of any long run relationship between gdp and the disaggregated public expenditure variables they do support the existence of short run causation implying that national income may be causing or caused by a component of the total government current expenditure in the short run

macroeconomic effects of fiscal policy in pakistan a disaggregate analysis abstractthis study analyzes the macroeconomic effects of fiscal policy on macroeconomic variables in pakistan the study utilizes var framework and uses quarterly data of pakistan from 1976q1 to 20

shifts in volatility driven by large stock market shocks abstract this paper presents an extension of the stochastic volatility model which allows for level shifts in volatility of stock market returns known as structural breaks these shifts are endogenously driven by large return shocks innovations reflecting large pieces of market news these shocks are identified from the data as being bigger in absolute terms than the values of two threshold parameters of the model one for the negative shocks and one for the positive shocks the model can be employed to investigate different sources of stock market volatility shifts driven by market news without relying on exogenous information in addition to this it has a number of interesting features which enable us to study the effects of large return shocks on future levels of market volatility the above properties of the model are shown based on a study for the us stock market volatility

human capital committee power and legislative outcomes this paper presents a model in which legislators use informational asymmetries to engage in rent seeking behavior previous work in the informational and distributive traditions could not explain deviations from the median preference without reference to committee power integration of these forces demonstrated that legislative outcomes need not correspond to the median preference regardless of the extent to which committee power is present in a legislature while deviations from the median preference are consistent with committee power recent empirical evidence suggests that observed deviations in congress are in fact caused by human capital differentials rather than committee power

regularities in volatility and the price of risk following large stock market movements in the us and japan abstract we examine the effects of large price changes on volatility and the price of risk of two broad stock indices the crsp value weighted index of nyse and amex stocks and the topix of the tokyo stock exchange volatility generally rises after large price changes of either sign but usually revert to pre jump levels within a week or two in contrast the price of risk except for the first day after a jump typically declines following large price increases and rises following large price declines with little apparent tendency to revert toward pre jump levels before the arrival of the next jump

the savings growth nexus for the malaysian economy a view through rolling sub samples the purpose of this study is to re investigate the savings growth nexus for the malaysian economy using bounds testing approach to cointegration and toda and yamamoto 1995 and dolado and lutkepohl 1996 tydl granger causality test this study covered the sample period from 1971 q1 to 2008 q4 the cointegration results suggest that the variables are moving together in the long run and the tydl granger causality results indicate that the relationship between savings and economic growth is bilateral in addition the rolling sub samples tydl granger causality test exhibited a relatively stable causal relationship running from savings to economic growth in malaysia particularly before the onset of asian financial crisis in 1997 1998

on the origin of high persistence in garch models abstract we show that the baillie and chung 2001 minimum distance estimates of the garch 1 1 model induce spurious persistence in the volatility when there are structural changes in the mean of the process

a stochastic volatility model with markov switching this article presents a new way of modeling time varying volatility we generalize the usual stochastic volatility models to encompass regime switching properties the unobserved state variables are governed by a first order markov process bayesian estimators are constructed by gibbs sampling high medium and low volatility states are identified for the standard and poor s 500 weekly return data persistence in volatility is explained by the persistence in the low and the medium volatility states the high volatility regime is able to capture the 1987 crash and overlap considerably with four u s economic recession periods

keynes versus wagner public expenditure and national income for three african countries the public expenditure income hypothesis has long been debated in economics following keynes public expenditure is seen as an exogenous factor to be used as a policy instrument to influence growth on the other hand wagner argues that expenditure is an endogenous factor or an outcome not a cause of growth in national income the purpose of this paper is to apply both the granger and holmes hutton statistical procedures to test the income expenditure hypothesis for three african countries ghana kenya and south africa we find that the hypothesis of public expenditure causing national income is not supported by the data for these african countries

congressional committees and the political economy of federal outlays the literature on the organization of the united states congress has been dominated by distributive and informational theory one important source of disagreement between these two theories is their characterization of whether individual legislators can engage in pork barrel activities here we provide evidence which indicates that the pork barrel is alive and well in the contemporary united states congress we focus on whether members of power and constituency committees can direct disproportionate federal expenditures to their districts finding strong and systematic evidence of pork barrel activities by committee members provides empirical support for distributive theories of legislative organization

a theory of competition among pressure groups for political influence this paper presents a theory of competition among pressure groups for political influence political equilibrium depends on the efficiency of each group in producing pressure the effect of additional pressure on their influence the number of persons in different groups and the deadweight cost of taxes and subsidies an increase in deadweight costs discourages pressure by subsidized groups and encourages pressure by taxpayers this analysis unifies the view that governments correct market failures with the view that they favor the politically powerful both are produced by the competition for political favors

persistence in variance structural change and the garch model this article examines the persistence of the variance as measured by the generalized autoregressive conditional heteroskedasticity garch model in stock return data in particular we investigate the extent to which persistence in variance may be overstated because of the existence of and failure to take account of deterministic structural shifts in the model both an analysis of daily stock return data and a monte carlo simulation experiment confirm the hypothesis that garch measures of persistence in variance are sensitive to this type of model misspecification

why do markets move together an investigation of u s japan stock return comovements this article explores the fundamental factors that affect cross country stock return correlations using transactions data from 1988 to 1992 we construct overnight and intraday returns for a portfolio of japanese stocks using their nyse traded american depository receipts adrs and a matched sample portfolio of u s stocks we find that u s macroeconomic announcements shocks to the yen dollar foreign exchange rate and treasury bill returns and industry effects have no measurable influence on u s and japanese return correlations however large shocks to broadbased market indices nikkei stock average and standard and poor s 500 stock index positively impact both the magnitude and persistence of the return correlations stock return cross country covariances play a key role in international finance changes in these covariances affect the volatility of portfolios and asset prices as these covariances increase one expects that a fewer domestic risks are internationally diversifiable so portfolio volatility increases b the risk premium on the world market portfolio increases 1 c the cost of capital increases for individual firms and d the domestic version of the capm becomes increasingly inadequate 2 despite the important economic consequences of changes in cross country covariances the determinants of the levels and dynamics of these covariances have been little studied from an academic

on the mis measurement of legislator ideology and shirking in this paper we show that current statistical measures of legislator s shirking are implicitly based on the electoral concept of a unique majority rule equilibrium point in the policy space where elections are contested we note that such equilibria do not exist generically and present statistical results showing that cross sectional regressions where legislators voting indices are predicted by district average demograhic and economic data are mis specified we also discuss a weaker equilibrium construct the uncovered set and present statistical evidence showing that differences in voting behavior between senators from the same state are positively related to the heterogeneity of the electorate we argue that current evidence alleged to show shirking by senators is equally consistent with senators who perfectly represent an idiosyncratic constituency that cannot be represented by district average data

time series evidence on shirking in the u s house of representatives this paper presents time series evidence on the voting behavior of members of the u s house of representatives from 1975 to 1990 the empirical results indicate that voting behavior of individual congressmen is remarkably stable over time we find no evidence of economically significant last term effects on voting behavior nor are there important effects of legislative tenure on voting patterns the most significant deviations in voting behavior occur for congressmen who failed to win their reelection bid suggesting that sizable deviations from previous policy positions may result in swift retribution by constituents in the district

public expenditure and economic growth in the gulf cooperation council countries this article uses a dynamic model calibrated to the gulf cooperation council gcc countries data to examine the nature of the relationship between government expenditure and economic growth the article finds that national income is a predictive factor of the expanding role of government as postulated by wagner empirical investigations do not support the hypothesis of public expenditure causing national income as proposed by the keynesian theory
