the inflation tax in a real business cycle model money is incorporated into a real business cycle model using a cash in advance constraint the model economy is used to analyze whether the business cycle is different in high inflation and low inflation economies and to analyze the impact of variability in the growth rate of money in addition the welfare cost of the inflation tax is measured and the steady state properties of high and low inflation economies are compared

debt leases taxes and the endogeneity of corporate tax status we provide evidence that corporate tax status is endogenous to financing decisions which induces a spurious relation between measures of financial policy and many commonly used tax proxies using a forward looking estimate of before financing corporate marginal tax rates we document a negative relation between operating leases and tax rates and a positive relation between debt levels and tax rates this is the first unambiguous evidence supporting the hypothesis that low tax rate firms lease more and have lower debt levels than high tax rate firms many theories of capital structure imply that all else equal the incentive to use debt financing increases with a firm s marginal tax rate due to the tax deductibility of interest expense e g modigliani and miller 1963 deangelo and masulis 1980 conversely leasing models generally predict that firms with low marginal tax rates employ relatively more leases than do firms with high marginal tax rates the logic behind the leasinlg prediction is that leases allow for the transfer of tax shields from firms that cannot fully utilize the associated tax deduction lessees to firms that can lessors e g myers dill and bautista 1976 smith and wakeman 1985 ross westerfield and jaffe 1996 despite these straightforward predictions empirically testing for tax effects is difficult because a spurious relation exists between the financing decision and many commonly used tax proxies specifically both interest expense and lease payments are tax deductible thus a firm that finances its operations with debt or leases reduces its taxable income potentially lowering its expected marginal tax rate if not properly addressed this endogeneity of the tax rate can bias an experiment in favor of finding a negative

labor unemployment risk and corporate financing decisions this paper examines the impact of labor unemployment risk on corporate financing decisions theory suggests that firms choose conservative financial policies partly as a means of mitigating worker exposure to unemployment risk using changes in state unemployment insurance benefit laws as a source of variation in the costs borne by workers during layoff spells we explore the connection between unemployment risk and the corporate financing decisions of public firms in the united states we find that increases in legally mandated unemployment benefits lead to increases in corporate leverage the impact of reduced unemployment risk on financial policy is especially strong for firms that have greater layoff separation rates labor intensity and financing constraints the estimated premium required to compensate workers for unemployment risk due to financial distress is about 57 basis points of firm value for a bbb rated firm these findings suggest that labor market frictions have a significant impact on corporate financing decisions

uncertainty across volatility regimes we propose a nonrecursive identification scheme for uncertainty shocks that exploits breaks in the volatility of macroeconomic variables and is novel in the literature on uncertainty this approach allows us to simultaneously address two major questions in the empirical literature is uncertainty a cause or effect of decline in economic activity does the relationship between uncertainty and economic activity change across macroeconomic regimes results based on a small scale vector autoregression with us monthly data suggest that i uncertainty is an exogenous source of decline of economic activity and ii the effects of uncertainty shocks amplify in periods of economic and financial turmoil

handling financial resource mobilisation in technological innovation systems the case of chinese wind power to mitigate climate change a rapid and large scale expansion of sustainable innovations such as renewable energy technologies is crucial china s track record of wind power development shows both speed and scale that can provide valuable knowledge of how to stimulate and maintain transformation of energy systems the growth was made possible partly by ample access to financial capital however the rapid growth also led to growing pains and made the industry face increasing financial constraints while these constraints partly relate to structures and trends that are external to the wind power innovation system they were also a consequence of the particular path taken in chinese wind power development the case demonstrates that if a full fledged industry is to be developed and sustained a balanced growth is required and all innovation system functions need due attention sooner or later conceptually the article contributes by further exploring how mobilisation of financial resources affect and is affected by overall system dynamics

bankruptcy risk and optimal capital structure this study finds shortcomings in empirical tests of the capital structure irrelevance hypothesis the alternative hypothesis is that firms choose value maximizing mixes of debt and equity on account of bankruptcy costs and the tax deductibility of interest payments based upon the cross sectional implications of the tax shelter bankruptcy cost hypothesis an alternative test of the irrelevance hypothesis is performed the test examines the relationship between failure rates and leverage ratios for 36 lines of business the results are inconsistent with the irrelevance hypothesis in their landmark paper modigliani and miller 26 demonstrate that under certain assumptions the market value of a firm is independent of its capital structure these assumptions include the absence of taxes transactions costs and bankruptcy costs recently miller 24 has argued that the introduction of corporate and personal taxes does not alter the capital structure irrelevance result in the absence of bankruptcy costs 1 the inclusion of bankruptcy costs generally considered in conjunction with the tax deductibility of interest payments has led others to conclude that capital structure will affect the value of the firm 2 in this case value maximizing firms may choose optimal capital structures consisting of both debt and equity there have been numerous attempts to discriminate empirically between the miller irrelevance mi hypothesis and the tax shelter bankruptcy cost ts bc hypothesis several are discussed in section i of this paper there it is argued that studies attempting to measure directly the effect of changes in capital structure on firm values are subject to serious complications and are unable to discriminate between the mi and ts bc hypotheses other studies focus on cross sectional implications of the mi and ts bc hypotheses the cross sectional tests are based on the assertion that bankruptcy costs may tend to induce firms with greater business risk to include less debt in their capital structures whereas the mi hypothesis does not predict such a relationship unfortunately the existence of positive bankruptcy costs is not sufficient to ensure that the ts bc hypothesis will predict the inverse relation

seasonal solow residuals and christmas a case for labor hoarding and increasing returns in aggregate unadjusted data measured solow residuals exhibit large seasonal variations total factor productivity grows rapidly in the fourth quarter at an annual rate of 16 percent and regresses sharply in the first quarter at an annual rate of 24 percent how much of the total seasonal variation in the measured solow residual can be explained by christmas the answer to this question is surprising with increasing returns and time varying labor effort christmas is sufficient to explain the seasonal variation in the solow residual consumption average productivity and output in all four quarters our analysis of seasonally unadjusted data uncovers important roles for labor hoarding and increasing returns that are difficult to identify in adjusted data prescott 1986 has argued that the variability of solow s residual is a reasonable estimate of the variability of exogenous technology shocks when solow s residual is measured using seasonally unadjusted data for the postwar u s economy it exhibits large seasonal variations growing rapidly in the fourth quarter at an annual rate of 16 percent and falling sharply in the first quarter at an annual rate of 24 percent this paper starts from the premise that it is implausible to attribute seasonal variation of this magnitude to changes in the state of technology we present a model in which all seasonal fluctuations arise from a single demand shift christmas this demand shift together with misspecification of the traditional production function leads to large seasonal variation in the solow residual we consider two candidates for misspecification labor hoarding and external increasing returns to scale even when technological growth is aseasonal either candidate in isolation can induce spurious seasonality in the solow residual our general equilibrium analysis indicates that 1 the economy s seasonal patterns in all four quarters may be a response simply to a fourth quarter consumption demand shift and 2 a combination of labor hoarding and external increasing returns is important for replicating these patterns in aggregate quantity variables for the postwar u s economy since our analysis identifies important roles for labor hoarding and increasing returns these results have implications for nonseasonal macroeconomic models indeed our analysis im

nominal price rigidity money supply endogeneity and business cycles abstract this paper investigates the ability of nominal price rigidity to explain the co movement of inflation with the cyclical component of output observed in the post war u s data a dynamic general equilibrium model is constructed with the introduction of monopolistic competition and nominal price rigidity in a standard real business cycle model allowing for an endogenous money supply rule it is then demonstrated that sticky price models can explain the observed associations between movements in inflation and output much better than flexible price models this result depends little on whether money supply is assumed to be endogenous or not

tax avoidance cost of debt and shareholder activism evidence from korea abstract this paper examines the impact of tax avoidance on the cost of debt and its interaction effect with shareholder activism using korean firms i find a negative relationship between tax avoidance and the cost of debt supporting the trade off theory further tests reveal that the negative relationship becomes stronger when the level of institutional ownership is high it becomes even stronger after 1998 when the shareholder rights of institutional investors were strengthened it suggests that the managerial opportunism theory has an additional explanation for tax avoidance activities my findings indicate that tax avoidance reduces the cost of debt through trade offs and creates a managerial rent diversion which is mitigated in firms with larger institutional holdings

a new approach to decomposition of economic time series into permanent and transitory components with particular attention to measurement of the business cycle abstract this paper introduces a general procedure for decomposition of non stationary time series into a permanent and transitory component allowing both components to be stochastic the permanent component is shown to be a random walk with drift and the transitory or cyclical component is a stationary process with mean zero the decomposition methodology which depends only on past data and therefore is computable in real time is applied to the problem of measuring and dating business cycles in the portwar u s economy we find that measured expansions and contractions are of roughly equivalent duration and that our dating of cyclical episodes tends to lead the traditional nber dating and to a lesser extent the growth cycle chronology of zarnowitz and boschan 1977

control rights and capital structure an empirical investigation we show that incentive conflicts between firms and their creditors have a large impact on corporate debt policy net debt issuing activity experiences a sharp and persistent decline following debt covenant violations when creditors use their acceleration and termination rights to increase interest rates and reduce the availability of credit the effect of creditor actions on debt policy is strongest when the borrower s alternative sources of finance are costly in addition despite the less favorable terms offered by existing creditors borrowers rarely switch lenders following a violation a fundamental question in financial economics is how do firms choose their financial policies extant empirical research on this question has focused primarily on the presence of taxes and bankruptcy costs e g scott 1976 information asymmetry e g myers and majluf 1984 and more recently market timing behavior e g baker and wurgler 2002 however beginning with jensen and meckling 1976 a large body of theoretical research examines how incentive conflicts between managers and external investors affect corporate financial policies in particular theoretical research on financial contracting shows that in the presence of incentive conflicts optimal debt contracts will allocate certain rights to creditors after negative performance in order to help firms secure financing ex ante e g aghion and bolton 1992 and dewatripont and tirole

employee well being firm leverage and bankruptcy risk employees of liquidating firms are likely to lose income and non pecuniary benefits of working for the firm which makes bankruptcy costly for employees this paper examines whether firms take these costs into account when deciding on the optimal amount of leverage we find that firms with leading track records in employee well being significantly reduce the probability of bankruptcy by operating with lower debt ratios moreover we observe that firms with better employee track records have better credit ratings even when we control for differences in firm leverage

weak instrument robust tests in gmm and the new keynesian phillips curve we discuss weak instrument robust statistics in gmm for testing hypotheses on the full parameter vector or on subsets of the parameters we use these test procedures to reexamine the evidence on the new keynesian phillips curve model we find that u s postwar data are consistent with the view that inflation dynamics are predominantly forward looking but we cannot rule out the presence of considerable backward looking dynamics moreover the phillips curve has become flatter recently and this is an important factor contributing to its weak identification

liquidation costs and capital structure abstract we investigate the relation between liquidation costs of assets and composition of capital structure for firms that reorganized under chapter 11 of the bankruptcy code firms with high liquidation costs emerge from chapter 11 with relatively low debt ratios the debt of these firms is more likely to be public and unsecured and to have less restrictive covenant terms these firms are also more likely to raise new equity capital assets with high liquidation costs thus lead firms to choose capital structures that make financial distress less likely

interest rates and credit risk this paper explores the effects of shifts in interest rates on corporate leverage and default we develop a dynamic model in which the relationship between firms and their outside financiers is affected by a moral hazard problem and entrepreneurs initial wealth is scarce the link between leverage and default risk comes from the lower incentives of overindebted entrepreneurs to guarantee firm survival the need to finance new investment with outside funding pushes firms leverage ratio above some state contingent target towards which they gradually adjust through earnings retention the dynamic response of leverage and default to interest rate rises and cuts is both asymmetric and heterogeneously distributed across firms both rises and cuts increase the aggregate default rate in the short run however a higher interest rate reduces firms target leverage and hence produces lower default rates in the longer run this helps rationalize some evidence regarding the risk taking channel of monetary policy

debt and the marginal tax rate abstract do taxes affect corporate debt policy this paper tests whether the incremental use of debt is positively related to simulated firm specific marginal tax rates that account for net operating losses investment tax credits and the alternative minimum tax the simulated marginal tax rates exhibit substantial variation due to the dynamics of the tax code tax regime shifts business cycle effects and the progressive nature of the statutory tax schedule using annual data from more than 10 000 firms for the years 1980 1992 i provide evidence which indicates that high tax rate firms issue more debt than their low tax rate counterparts

are firms underleveraged an examination of the effect of leverage on default probabilities a commonly held view in corporate finance is that firms are less leveraged than they should be given the potentially large tax benefits of debt in this paper i study the effect of firms leverage on default probabilities as represented by the firms ratings using an instrumental variable approach i find that the leverage s effect on ratings is three times stronger than it is if the endogeneity of leverage is ignored this stronger effect results in a higher impact of leverage on the ex ante costs of financial distress which can offset the current estimates of the tax benefits of debt

indivisible labor and the business cycle abstract a growth model with shocks to technology is studied labor is indivisible so all variability in hours worked is due to fluctuations in the number employed we find that unlike previous equilibrium models of the business cycle this economy displays large fluctuations in hours worked and relatively small fluctuations in productivity this finding is independent of individuals willingness to substitute leisure across time this and other findings are the result of studying and comparing summary statistics describing this economy an economy with divisible labor and post war u s time series

on the existence of an optimal capital structure theory and evidence one of the most contentious issues in the theory of finance during the past quarter century has been the theory of capital structure the geneses of this controversy were the seminal contributions by modigliani and miller 18 19 the general academic view by the mid 1970s although not a consensus was that the optimal capital structure involves balancing the tax advantage of debt against the present value of bankruptcy costs no sooner did this general view become prevalent in the profession than miller 16 presented a new challenge by showing that under certain conditions the tax advantage of debt financing at the firm level is exactly offset by the tax disadvantage of debt at the personal level since then there has developed a burgeoning theoretical literature attempting to reconcile miller s model with the balancing theory of optimal capital structure e g deangelo and masulis 5 kim 12 and modigliani 17 the general result of this work is that if there are significant leverage related costs such as bankruptcy costs agency costs of debt and loss of non debt tax shields and if the income from equity is untaxed then the marginal bondholder s tax rate will be less than the corporate rate and there will be a positive net tax advantage to corporate debt financing the firm s optimal capital structure will involve the trade off between the tax advantage of debt and various leverage related costs the upshot of these extensions of miller s model is the recognition that the existence of an optimal capital structure is essentially an empirical issue as to whether or not the various leverage related costs are economically significant enough to influence the costs of corporate borrowing the miller model and its theoretical extensions have inspired several timeseries studies which provide evidence on the existence of leverage related costs trczinka 28 reports that from examining differences in average yields between taxable corporate bonds and tax exempt municipal bonds one cannot reject the miller hypothesis that the marginal bondholder s tax rate is not different from the corporate tax rate however trczinka is careful to point out that this finding does not necessarily imply that there is no tax advantage of corporate debt if the personal tax rate on equity is positive indeed buser and hess 1 using a longer time series of data and more sophisticated econometric techniques estimate that the average effective personal tax rate on equity is statistically positive and is not of a trivial magnitude more importantly they document evidence that is consistent with the existence of significant leverage related costs in the economy

do expected future marginal costs drive inflation dynamics abstract this article discusses a more general interpretation of the two step minimum distance estimation procedure proposed in sbordone 2002 the estimator is again applied to a version of the new keynesian phillips curve where inflation dynamics are driven by the expected evolution of marginal costs the article clarifies econometric issues addresses concerns about uncertainty and model misspecification raised in recent studies and assesses the robustness of previous results while confirming the importance of forward looking terms in accounting for inflation dynamics it suggests how the methodology can be applied to extend the analysis of inflation to a multivariate setting

the maturation and growth of infant industries the case of korea abstract this paper first shows that contrary to evidence from most developing countries korean infant industries under protection have tended to mature it also shows that output grows faster in infant industries than in mature ones the paper then discusses probable factors that have made the maturation and growth of infant industries possible in korea overall the empirical evidence and its interpretation support the revisionist rather than neoclassical or market friendly view in the recent debate on east asian industrialization

have the tax benefits of debt been overestimated abstract we re examine the claim that many corporations are underleveraged in that they fail to take full advantage of debt tax shields we show prior results suggesting underleverage stems from biased estimates of tax benefits from interest deductions we develop improved estimates of marginal tax rates using a non parametric procedure that produces more accurate estimates of the distribution of future taxable income we show that additional debt would provide firms with much smaller tax benefits than previously thought and when expected distress costs and difficult to measure non debt tax shields are also considered it appears plausible that most firms have tax efficient capital structures

the east asian miracle study does the bell toll for industrial strategy the world bank s east asian miracle study1 has been anticipated with considerable interest by the development community it was intended not least by the japanese government that financed it to be an objective re examination of the role of government interventions in economic particularly industrial development it reflected a widespread unease that the bank was too strongly committed to a neoliberal view of the development process 2 this approach evolved over the 1980s drawing mainly upon evidence from east asia and fuelled by a shift in mainstream economics and political perceptions in the leading developed countries it formed the basis of the bank s subsequent lending and policy advice and was at the core of the structural adjustment programs that have shaped policy in many developing countries this review confines itself to the study s analysis of industrial policy concentrating on the approach and the analysis of the established nies the four tigers

monopolistic competition and the effects of aggregate demand how important is monopolistic competition to an understanding of the effects of aggregate demand on output we ask the question at three levels can monopolistic competition by itself explain why aggregate demand movements affect output can it together with other imperfections generate effects of aggregate demand in a way that perfect competition cannot if so can it give an accurate account of the response of the economy to aggregate demand movements the answers are no yes and yes

sticky goods prices flexible asset prices monopolistic competition and monetary policy a monetary general equilibrium asset pricing model with sticky goods prices is developed goods prices are set by monopolistically competitive firms that maximize stock market value equilibria with underutilization of resources excess capacity in some states result in contrast to previous monetary asset pricing models the degree of competition affects capacity utilization monetary policy can affect output and resource utilization in addition to real asset prices depending upon the amount of information available to the monetary authority

the length of the infant industry period evidence from the engineering industry in south korea abstract in the literature on industrialization very little is known about the length of the infant industry period this paper argues that the paucity of knowledge in this area is a serious weakness evidence from perhaps the most successful country of the past 20 years south korea suggests that the learning time in the engineering industry is much longer than anticipated two decades does not seem to be unusual it is also argued that due to both the speed of technical change and the globalization of industries the learning time has been extended in the past decades tentative implications are drawn for industrialization models and for industrial policy

identification weak instruments and statistical inference in econometrics we discuss statistical inference problems associated with identification and testability in econometrics we consider inference in non parametric models and weakly identified structural models weak instruments we point out that many ill defined statistical problems such as non testable hypotheses occur in these areas and are typically associated with asymptotic approximations in non parametric models such problems include testing moments and inference under heteroscedasticity or serial dependence of unknown form for weakly identified structural models difficulties are typically associated with improper pivots and we review recent developments aimed at proposing more reliable procedures including alternative proposed statistics bounds projection split sampling conditioning monte carlo tests jel classification c1 c12 c14 c15 c3 c5 identification instruments faibles et inference statistique en econometrie nous analysons les problemes d inference associes a l identification et a la testabilite en econometrie nous considerons l inference dans les modeles non parametriques et les modeles structurels faiblement identifies instruments faibles nous remarquons que beaucoup de problemes mal poses tels que des hypotheses non testables apparaissent dans ces domaines et que ceux ci sont typiquement associes a l emploi d approximations asymptotiques dans les modeles non parametriques de tels problemes incluent les tests sur les moments et l inference sous heteroscedasticite ou dependance serielle de forme non specifiee dans les modeles structurels faiblement identifies ces difficultes sont habituellement associees a l emploi de fonctions pivotales impropres et nous presentons un survol des methodes recentes ayant pour objectif d obtenir des procedures plus fiables ce qui comprend les differentes statistiques proposees l emploi de bornes la subdivision d echantillon les techniques de projection le conditionnement et les tests de monte carlo

human capital capital structure and employee pay an empirical analysis abstract we test the predictions of titman 1984 and berk stanton and zechner 2010 by examining the effect of leverage on labor costs leverage has a significantly positive impact on cash equity based and total compensation of chief executive officers ceos compensation of new ceos hired from outside the firm is positively related to prior year firm leverage in addition leverage has a positive and significant impact on average employee pay the incremental total labor expenses associated with an increase in leverage are large enough to offset the incremental tax benefits of debt the empirical evidence supports the theoretical prediction that labor costs limit the use of debt

mr keynes and the neo schumpeterians contributions to the analysis of the determinants of innovation from a post keynesian perspective abstract the purpose of this paper is to discuss the importance of knowledge both tacit and codified in the formation of the state of long term expectations that drive firms decisions to search for innovation and to investment in r d the paper takes the post keynesian theory as reference associating it with the neo schumpeterian analysis of innovation dynamics first it is argued that knowledge plays a crucial role in building agents confidence emphasizing that radical innovations are more dependent on the accumulation of codified knowledge given the higher degree of uncertainty associated with this type of innovation while incremental innovations are more dependent on tacit knowledge about the current market conditions and technological trajectory second it is argued that the accumulation of knowledge and the constant introduction of innovations foster the creation of a convention to innovate which facilitates the decision to pursue innovations by influencing long term expectations

proxies for the corporate marginal tax rate abstract this paper focuses on how best to measure the corporate marginal tax rate which is an important input into financial analysis of the cost of capital financing policy corporate hedging and corporate reorganizations the results indicate that the simulated tax rate used by shevlin 1990 and graham 1996 although difficult to calculate is the best available proxy for the true marginal tax rate if the simulated rate is unavailable an easy to calculate trichotomous variable or the statutory marginal tax rate which captures the progressivity in the tax schedule are reasonable alternatives better than most commonly used tax variables

productivity shocks and real business cycles abstract productivity shocks play a central role in real business cycles as an exogenous impulse to macroeconomic activity however measured solow prescott residuals do not behave as an exogenous impulse rather econometric evidence provided in this paper indicates that 1 money interest rates and government spending granger cause these impulses and 2 a substantial component of the variance of these impulses between one quarter and one half is attributable to variations in aggregate demand these results are robust to a number of econometric issues including measurement errors specification of the production function and certain forms of omitted real variables

monetary policy and long run systemic risk taking as an extension to the literature on the risk taking channel of monetary policy this paper studies the existence of a systemic risk taking channel srtc in the eurozone through an original macroeconomic perspective based on causality measures because the srtc is effective after an incubation period we make a distinction between short and long term causality following the methodology proposed by dufour and taamouti 2010 we find that causality from monetary policy to systemic risk while not significant in the very short term robustly represents 75 to 100 of the total dependence between the two variables in the long run reverse causality is rejected systemic risk did not influence the policy of the european central bank before the global financial crisis however central banks must be aware that a too loose monetary policy stance may be conducive to a build up of systemic risk

do firms hedge in response to tax incentives there are two tax incentives for corporations to hedge to increase debt capacity and interest tax deductions and to reduce expected tax liability if the tax function is convex we test whether these incentives affect the extent of corporate hedging with derivatives using an explicit measure of tax function convexity we find no evidence that firms hedge in response to tax convexity our analysis does however indicate that firms hedge to increase debt capacity with increased tax benefits averaging 1 1 percent of firm value our results also indicate that firms hedge because of expected financial distress costs and firm size an increasing number of corporations use financial derivatives each year the international swaps and derivatives association reports that the notional value of outstanding otc swap contracts increased from 11 3 trillion in 1994 to more than 60 trillion by mid 2000 http 00www isda org this is interesting because financial theory tells us that corporate risk management enhances value only in the presence of costly market imperfections a number of empirical studies examine derivative holdings to identify which of the proposed theoretical incentives and imperfections lead to corporate hedging our paper adds to the hedging literature by testing whether corporations respond to two tax related incentives to hedge the incentive to reduce volatility thereby increasing debt capacity and the tax benefits of debt and the incentive to reduce expected tax liabilities by reducing the volatility of taxable income we also use a refined dependent variable to measure net

trend inflation indexation and inflation persistence in the new keynesian phillips curve purely forward looking versions of the new keynesian phillips curve nkpc generate too little inflation persistence some authors add ad hoc backward looking terms to address this shortcoming we hypothesize that inflation per sistence results mainly from variation in the long run trend component of inflation which we attribute to shifts in monetary policy we derive a version of the nkpc that incorporates a time varying inflation trend and examine whether it explains the dynamics of inflation when drift in trend inflation is taken into account a purely forward looking version of the model fits the data well and there is no need for backward looking components jel e12 e31 e52 in this paper we consider the extent to which guillermo calvo s 1983 model of nominal price rigidities can explain inflation dynamics without relying on arbitrary backward looking terms in its baseline formulation the calvo model leads to a purely forward looking new keynesian

were there regime switches in u s monetary policy working paper 2004 14 june 2004 abstract a multivariate model identifying monetary policy and allowing for simultaneity and regime switching in coefficients and variances is confronted with u s data since 1959 the best fit is with a model that allows time variation in structural disturbance variances only among models that also allow for changes in equation coefficients the best fit is for a model that allows coefficients to change only in the monetary policy rule that model allows switching among three main regimes and one rarely and briefly occurring regime the three main regimes correspond roughly to periods when most observers believe that monetary policy actually differed and the differences in policy behavior are substantively interesting though statistically ill determined the estimates imply monetary targeting was central in the early 80s but was also important sporadically in the 70s the changes in regime were essential neither to the rise in inflation in the 70s nor to its decline in the 80s jel classification e52 e47 c53 key words counterfactuals lucas critique policy rule monetary targeting simultaneity volatility model comparison i the debate over monetary policy change in an influential paper clarida gali and gertler 2000 cgg presented evidence that us monetary policy changed between the 1970 s and the 1980 s indeed that in the 70 s it was drastically worse they found that the policy rule apparently followed in the 70 s was one that when embedded in most stochastic general equilibrium models would imply non uniqueness of the equilibrium and hence vulnerability of the economy to sunspot fluctuations of arbitrarily large size their estimated policy rule for the later period on the other hand eliminated this indeterminacy these results are a possible explanation of the volatile and rising inflation of the 70 s and of its subsequent decline the cgg analysis has two important weaknesses one is that it fails to account for stochastic volatility us macroeconomic variables and particularly the federal funds rate have gone through periods of tranquility and of agitation with forecast error variances varying greatly from period to period ignoring such variation does not lead to inconsistent estimates of model parameters when the forecasting equations themselves are constant but it strongly biases toward a finding of changed parameters tests of the stability of the forecasting equations the other weakness is that the cgg analysis rests on powerful and implausible identifying assumptions they require that we accept that the response of the monetary authority to expected future inflation and output does not depend on the recent history of inflation money growth or output it is hard to understand why this should be so especially in the 70 s when monetarism was a prominent theme in policy debates congress was requiring reports from the fed of projected time paths of monetary aggregates and financial markets were reacting sensitively to weekly money supply numbers the requirement for existence and uniqueness of equilibrium in dynamic models is that the monetary policy rule show a more than unit response of interest rates to the sum of the logs of all nominal variables that appear on the right hand side of the reaction function if we force a particular measure of expected future inflation to proxy for all the nominal variables that actually appear independently in the reaction function we are bound to get distorted conclusions on the one hand because expected future inflation will be a noisy measure of the full set of nominal influences on policy we might get downward bias in our estimates from the usual errorsin variables effect on the other hand to the extent that expected future inflation like most expected future values shows less variation than current nominal variables we could find a mistaken scaling up of coefficients

indirect costs of financial distress in durable goods industries the case of auto manufacturers financial distress can disrupt a durable goods producer s provision of complementary goods and services such as warranties spare parts and maintenance this reduces consumers demand for the core product causing indirect costs of financial distress we test this hypothesis in the market for used cars sold at wholesale auctions an increase in a manufacturer s credit default swaps significantly decreases the prices of its cars at auction especially cars with longer expected service lives our estimates imply substantial indirect costs of financial distress for car manufacturers these costs have occasionally even exceeded the tax savings benefits for general motors and ford the author 2013 published by oxford university press on behalf of the society for financial studies all rights reserved for permissions please e mail journals permissions oup com oxford university press

identication using stability restrictions this paper studies inference in models that are identified by moment restrictions we show how instability of the moments can be used constructively to improve the identification of structural parameters that are stable over time a leading example is macroeconomic models that are immune to the well known lucas 1976 critique in the face of policy regime shifts this insight is used to develop novel econometric methods that extend the widely used generalized method of moments gmm the proposed methods yield improved inference on the parameters of the new keynesian phillips curve

an exogeneity test for a simultaneous equation tobit model with an application to labor supply a test of weak exogeneity in the simultaneous equation tobit model is proposed and illustrated using a female labour supply model estimated using cross section data the test statistic can be simply output from any standard tobit maximum likelihood package and is asymptotically efficient the procedure provides consistent estimators for the simultaneous tobit model whose asymptotic covariance matrix is a simple extension of the usual tobit formula we also provide the lagrange multiplier test of weak exogeneity this abstract was borrowed from another version of this item

quality and productivity in the competitive strategies of brazilian industrial enterprises abstract after a long period of protected development brazilian industry is facing the new competition an analysis of manufacturing based competitive strategies in developed countries shows a trajectory of development of competitiveness starting from price and moving through quality time diversity and uniqueness the competences needed for each element are cumulative this poses challenges for firms in developing countries which are faced with a sudden exposure to new standards of competitiveness they may recognize the need for better quality or diversity but not have the basis for achieving them the problems facing firms in brazil as they wrestle with these problems in a liberalizing economy are discussed

on the determinants of corporate hedging finance theory indicates that hedging increases firm value by reducing expected taxes expected costs of financial distress or other agency costs this paper provides evidence on these hypotheses using survey data on firm s use of forwards futures swaps and options combined with computstat data on firm characteristics of 169 firms in the sample 104 firms use hedging instruments in 1986 the data suggest that firms which hedge face more convex tax functions have less coverage of fixed claims are larger have more growth options in their investment opportunity set and employ fewer hedging substitutes
