nonlinear effects of exchange rate volatility on the volume of bilateral exports in this paper we investigate empirically the impact of exchange rate volatility on real international trade flows utilizing a 13 country data set of monthly bilateral real exports for 1980 1998 we compute one month ahead exchange rate volatility from the intra monthly variations in the exchange rate to better quantify this latent variable we find that the effect of exchange rate volatility on trade flows is nonlinear depending on its interaction with the importing country s volatility of economic activity and that it varies considerably over the set of country pairs considered copyright 2003 john wiley sons ltd

asymmetric loan loss provision models abstract large net loan charge offs are frequently associated with large decreases in nonperforming loans and large increases in loan loss provisions inducing a v shaped relation between loan loss provisions and nonperforming loan changes failure to model the asymmetry attributable to net loan charge offs can change inferences about the presence of earnings management and the effects of delayed loan loss recognition in prior papers that assumed linearity future researchers should either include net loan charge offs in linear models of loan loss provisions or explicitly model the asymmetry induced by omitting net loan charge offs

investment uncertainty and liquidity we analyze the dynamic investment decision of a firm subject to an endogenous financing constraint the threat of future funding shortfalls lowers the value of the firm s timing options and encourages acceleration of investment beyond the first best optimal level as well as highlighting another way by which capital market frictions can distort investment behavior this result implies that 1 the sensitivity of investment to cash flow can be greatest for high liquidity firms and 2 greater uncertainty has an ambiguous effect on investment

u s bilateral trade flows and exchange risk during the floating period abstract this paper tests for real exchange rate risk effects on u s bilateral trade flows during the floating period using several new as well as previously used risk measures significant negative effects occur in five of six u s import flows and in two of six u s export flows with one export flow showing a significant positive effect these results are consistent with several previous findings for aggregate u s trade two risk measures using the forward exchange rate and assuming a time varying risk premium provide marginally more significant results than the others

product market competition and the impact of price uncertainty on investment some evidence from us manufacturing industries the authors estimate the impact of price uncertainty on investment using a panel of u s manufacturing industries pooling the data for all industries uncertainty has no impact on current investment however for industries that have low levels of seller concentration and thus are likely to be highly competitive the estimated impact is negative and statistically significant while for industries with high levels of seller concentration the impact is always small and not significantly different from zero the finding of a negative relationship between investment and price uncertainty in competitive industries is broadly consistent with models that incorporate irreversibility of capital investment copyright 1996 by blackwell publishing ltd

exchange rate volatility international trade and resource allocation a perspective on recent research abstract recent research on the effects of exchange rate volatility is discussed and directions for future research are explored the need to pay more attention to the effects of diversification and firms characteristic is emphasized it is suggested that while international risk has risen substantially since floating the differential between international and domestic risk may not this could help explain the failure of international trade to fall drastically and suggests that exchange rate volatility has been more a reflection than an independent cause of underlying instability

on the investment sensitivity of debt under uncertainty abstract we investigate the impact of debt on a panel of u s manufacturing firms capital investment behavior as the underlying firm specific and market level uncertainty changes our estimates show that the influence of leverage on capital investment may be stimulating or mitigating depending on the effects of uncertainty

the impact of exchange rate volatility on international trade reduced form estimates using the garch in mean model abstract in this paper we use a multivariate garch in mean model of the reduced form of multilateral exports to examine the relationship between nominal exchange rate volatility and export flows and prices the model imposes rationality on perceived exchange rate volatility unlike conventional two step strategies tests are performed for five industrialized countries over the post bretton woods era we find that the garch conditional variance has a statistically significant impact on the reduced form equations for all countries for most of the countries the magnitude of the effect is stronger for export prices than quantities in addition the estimated magnitude of the impact of volatility on exports is not robust to using the conventional estimation strategy jel f41 f31

earnings quality in uk private firms comparative loss recognition timeliness abstract uk private and public companies face substantially equivalent regulation on auditing accounting standards and taxes we hypothesize that private company financial reporting nevertheless is of lower quality due to different market demand regulation notwithstanding a large uk sample supports this hypothesis quality is operationalized using basu s 1997 time series measure of timely loss recognition and a new accruals based method the result is not affected by controls for size leverage industry membership and auditor size or by allowing endogenous listing choice the result enhances understanding of private companies which are predominant in the economy it also provides insight into the economics of accounting standards

managing unanchored heterogeneous expectations and liquidity traps abstract we study the possibility of almost self fulfilling waves of optimism and pessimism and self fulfilling liquidity traps in a new keynesian model with a continuum of heterogeneous expectations in particular all agents choose based on past forecasting performance expectation values out of a distribution around the targets of the central bank this framework allows us to explicitly model the anchoring of expectations as the variance of this distribution of possible expectation values we find that when the zero lower bound on the nominal interest rate is not binding adequate monetary policy can prevent waves of optimism and pessimism and exclude near unit root dynamics even when expectations are unanchored however as shocks bring the economy to a situation with a binding zero lower bound there is a danger of a long lasting self fulfilling liquidity trap that can take the form of a deflationary spiral this can be prevented if expectations are strongly enough anchored to the targets or if the inflation target is high enough

uncertainty determinants of firm investment abstract we investigate the impact of measures of uncertainty on firms capital investment behavior using a panel of u s firms increases in firm specific and capm based measures have a significant negative effect on investment spending while market based uncertainty has a positive impact

animal spirits risk premia and monetary policy at the zero lower bound abstract in this paper we investigate the risk related effects of monetary policy in normal times as well as in periods where the zero lower bound zlb binds in a stylized macroeconomic model with boundedly rational beliefs in our model financial market participants use heuristics to assess the risk premium over the policy rate in accordance to an implicit taylor rule that measures the stance of conventional monetary policy and which serves as an informative instrument during times when the funds rate is constrained by the zlb in such a case conventional monetary policy is exhausted so that the central bank is forced to use unconventional types of policy we propose alternative monetary policy measures to help the economy out of the liquidity trap which take into account this assumed form of bounded rationality

inventories sales uncertainty and financial strength abstract we investigate the empirical linkages between sales uncertainty and firms inventory investment behavior while controlling for firms financial strength using large panels of manufacturing firms from several european countries we find that higher sales uncertainty leads to larger stocks of inventories we also identify an indirect effect of sales uncertainty on inventory accumulation through the financial strength of firms our results provide evidence that financial strength mitigates the adverse effects of uncertainty

the power of forward guidance revisited in recent years central banks have increasingly turned to forward guidance as a central tool of monetary policy especially as interest rates around the world have hit the zero lower bound standard monetary models imply that far future forward guidance is extremely powerful promises about far future interest rates have huge effects on current economic outcomes and these effects grow with the horizon of the forward guidance we show that the power of forward guidance is highly sensitive to the assumption of complete markets if agents face uninsurable income risk and borrowing constraints a precautionary savings effect tempers their responses to changes in future interest rates as a consequence forward guidance has substantially less power to stimulate the economy in addition we show that the business cycle dynamics of our incomplete markets model differ substantially from its complete market counterpart this contrasts with the well known results of krusell and smith 1998 we present approximate representations that can easily be incorporated into standard business cycle models

the new keynesian liquidity trap abstract many new keynesian models produce a deep recession with deflation at the zero bound these models also make unusual policy predictions useless government spending technical regress capital destruction and forward guidance can raise output moreover these predictions are larger as prices become less sticky and as changes are expected further in the future i show that these predictions are strongly affected by equilibrium selection for the same interest rate path equilibria that bound initial jumps predict mild inflation small output variation negative multipliers small effects of far off expectations and a smooth frictionless limit fiscal policy considerations suggest the latter equilibria

the effects of macroeconomic stability on foreign trade an analysis for spain 1986 2000 two main factors underlie the rebirth of interest in the study of the influence of the real exchange rate on trade the reduction of its volatility and the current trend towards price stability the objective of this study is to analyse the effects of the process of nominal convergence required of the european member states for the fulfilment of monetary integration on foreign trade flows the case of spain which is especially interesting in this context is studied for the period 1986 to 2000 the results of estimating the aggregate functions of the export and import of goods shows how macroeconomic stability has altered the behaviour of trade with respect to the two basic determinants income and prices how it has caused a significant structural change in the real exchange rate and finally how it has laid the explanatory bases for transactions in the twenty first century with the single currency the euro

fiscal policy and monetary integration in europe fiscal policy economists policy makers and the media often argue that the maastricht treaty and the stability and growth pact make it difficult for governments of emu countries to stabilize their economies with appropriate fiscal policy and to provide adequate public investment our empirical analysis offers little support to this view discretionary budget deficits have actually become more counter cyclical in emu countries after the maastricht treaty as well as in the other eu and non eu industrialized countries we study and while public investment has declined recently in emu countries a similar tendency is apparent in other countries and started well before the maastricht treaty was signed jordi gali and roberto perotti

hard or soft pegs choice of exchange rate regime and trade in africa summary this paper revisits the link between fixed exchange rate regimes and trade in the context of africa s exchange rate arrangements differentiating the effects of hard pegs currency unions from conventional soft pegs using a novel dataset of exchange rate regime classification the paper augments the gravity model of bilateral trade flows with measures of currency unions and conventional pegged arrangements and benchmarks africa s experience against the rest of the world we find that in both samples currency unions and pegs increase trade vis a vis more flexible exchange rate arrangements through channels in addition to reduced exchange rate volatility however the effect is almost twice as large for africa in addition the trade generating effect of pegs is at least as large for africa as that of currency unions suggesting that pegs could present a viable option perhaps an alternative to currency unions to promote trade in the region

industry wide versus firm specific uncertainty and investment british company panel data evidence this paper presents evidence on the prediction that the impacts of firm specific and industry wide uncertainty on investment will be different results show that these work in opposing directions and that the effect of industry specific uncertainty is stronger in concentrated industries

the role of accruals in asymmetrically timely gain and loss recognition we investigate the role of accrual accounting in the asymmetrically timely recognition incorporation in reported earnings of gains and losses timely recognition requires accruals when it precedes complete realization of the gains and losses in cash we show that nonlinear accruals models incorporating the asymmetry in gain and loss recognition timelier loss recognition or conditional conservatism offer a substantial specification improvement explaining substantially more variation in accruals than equivalent linear specifications conversely conventional linear accruals models by omitting the loss recognition asymmetry exhibit substantial attenuation bias and offer a comparatively poor specification of the accounting accrual process linear specifications also understate the ability of current earnings to predict future cash flows these findings have implications for our understanding of accrual accounting and conservatism as well as for researchers estimating discretionary accruals earnings management and earnings quality

international trade and exchange rate volatility for currencies with well developed forward markets several papers have investigated the conjectured negative relationship between trade and short term exchange rate volatility without being very successful a theoretical explanation for the empirical anomalies is provided by solving explicitly for the forward rate because importers and exporters are on opposite sides of the forward market so is their exposure towards exchange rate volatility moreover which trade flow benefits and which one loses from increased volatility is determined by the signs of the aggregate net foreign currency exposure and the aggregate measure of risk aversion

exchange rate uncertainty and foreign trade abstract this paper starts with reviewing the existing literature on exchange rate uncertainty and trade flows it then argues that potential costs of medium term uncertainty in exchange rates and competitiveness are likely to be much larger than that of exchange risk which has been the focus of the existing literature two measures of medium term exchange rate uncertainty are constructed one is a weighted function of the magnitude of past movements in nominal exchange rates and the current deviation of the exchange rate from equilibrium while the second depends on both the duration and the amplitude of misalignment from equilibrium exchange rates the empirical evidence reported in the paper suggests that when exchange rate uncertainty is defined over a medium term period it does affect adversely trade flows of the industrial countries under review with the notable exception of the united states

heterogeneity in the dynamic effects of uncertainty on investment how does aggregate profit uncertainty influence investment activity at the firm level we propose a parsimonious adaptation of a factor autoregressive conditional heteroscedasticity model to exploit information in a subindustry sales panel for an efficient and tractable estimation of aggregate volatility

inflation targeting and liquidity traps under endogenous credibility abstract policy implications are derived for an inflation targeting central bank whose credibility is endogenous and depends on its past ability to achieve its targets this is done in a new keynesian framework with heterogeneous and boundedly rational expectations we find that the region of allowed policy parameters is strictly larger than under rational expectations however when the zero lower bound on the nominal interest rate is accounted for self fulfilling deflationary spirals can occur depending on the credibility of the central bank deflationary spirals can be prevented with a high inflation target and aggressive monetary easing

the effects of real exchange rate risk on international trade abstract by assuming real profit maximization and uncertain prices as well as exchange rates we conclude that it is uncertain percentage changes in the real exchange rate that are risky in international trade empirical estimation of fourteen bilateral trade flows among industrialized countries finds a significant negative effect on trade quantity from such risk in a number of these cases the expectation variable has a positive effect in a larger number of cases significant price effects from the expectation variable are fewer and from risk are negligible

patent protection market uncertainty and r d investment the real options investment theory shows that greater uncertainty about market revenues reduces current r d investment by increasing the value of waiting this paper presents empirical evidence that patent protection mitigates the effect market uncertainty on r d investment

a new keynesian model with heterogeneous expectations abstract within a new keynesian model we incorporate bounded rationality at the individual agent level and we determine restrictions on expectations operators sufficient to imply aggregate is and as relations of the same functional form as those under rationality this result provides dual implications the strong nature of the restrictions required to achieve aggregation serve as a caution to researchers imposing heterogeneous expectations at an aggregate level may be ill advised on the other hand accepting the necessary restrictions provides for tractable analysis of expectations heterogeneity as an example we consider a case where a fraction of agents are rational and the remainder are adaptive and find specifications that are determinate under rationality may possess multiple equilibria in case of expectations heterogeneity

investment and uncertainty is there a potential role for a common european policy abstract this paper contributes to the long running debate on the relationship between uncertainty and investment our results show that uncertainty negatively affects investment they are also favorable towards a common european economic policy oriented both to the support and the stabilization of aggregate demand

corporate investment in emerging markets the role of commodity prices we examine how firm level and country specific macroeconomic variables determine corporate investment in emerging markets in particular we investigate how investment decisions are affected by changes in country specific commodity export prices using firm level data from 38 emerging markets for the period 1990 2013 we show that in addition to the standard firm level variables such as expected future profitability cash flows leverage and new debt flows commodity export prices play a significant role in driving corporate investment moreover we show that the sharp decline in commodity prices since 2011 has been a key factor explaining the sizable slowdown in private investment growth during this period especially in regions with large net commodity exporters

do delays in expected loss recognition affect banks willingness to lend abstract banks can decrease their future capital inadequacy concerns by reducing lending the capital crunch theory predicts that lending is particularly sensitive to regulatory capital constraints during recessions when regulatory capital declines and external financing frictions increase regulators and policy makers argue that the current loan loss provisioning rules magnify this pro cyclicality exploiting variation in the delay in expected loss recognition under the current incurred loss model we find that reductions in lending during recessionary relative to expansionary periods are lower for banks that delay less we also find that smaller delays reduce the recessionary capital crunch effect these results hold across management quality partitions

measuring and analysing the effects of short term volatility in real exchange rates this paper examines short term volatility in the real effective exchange rates of industrial countries and its impact on their imports it yields three conclusions first volatility has not diminished as markets have gained experience with floating exchange rates the trend appears to be in the opposite direction for some countries second exposure to short term volatility has differed among countries japan and sweden have experienced much more than most other industrial countries third volatility appears to depress the volume of international trade this third finding is consistent with results reported by cushman and by akhtar and hilton and challenges earlier findings by hooper and kohlhagen

real exchange rate volatility and the us bilateral trade a var approach this paper uses var models to investigate the impact of real exchange rate volatility on u s bilateral imports from the united kingdom france germany japan and canada the var systems include u s and foreign macro variables and are estimated separately for each country the major results suggest that the effect of volatility on imports is weak although permanent shocks to volatility do have a negative impact on this measure of trade and those effects are relatively more important over the flexible rate period copyright 1989 by mit press

exchange rate volatility and international trading strategy abstract it is usually argued that an increase in exchange rate volatility reduces the volume of international trade as trading firms are risk averse this paper shows that exporting firms benefit under fairly general conditions from an increase in exchange rate volatility firms optimally adjust their export volumes to the level of the exchange rate exporting is an option which is exercised if profitable in addition the paper presents conditions under which the volume of international trade grows with exchange rate volatility

booms and busts in economic activity a behavioral explanation booms and busts in economic activity are a regular occurrence they lead to a strong empirical regularity i e that output gaps and output growth are non normally distributed mainstream macroeconomic models explain this phenomenon by invoking exogenous shocks that are non normally distributed this is not a very satisfactory explanation as it shifts our ignorance one step further i propose an explanation based on a behavioral macroeconomic model in which agents are assumed to have limited cognitive abilities and thus develop different beliefs this model produces waves of optimism and pessimism in an endogenous way animal spirits and provides for a better endogenous explanation of the observed non normality in output movements i also analyze the implications for monetary policy

the optimal inflation rate in new keynesian models should central banks raise their inflation targets in light of the zero lower bound we study the effects of positive steady state inflation in new keynesian models subject to the zero bound on interest rates we derive the utility based welfare loss function taking into account the effects of positive steady state inflation and solve for the optimal level of inflation in the model for plausible calibrations with costly but infrequent episodes at the zero lower bound the optimal inflation rate is low typically less than two percent even after considering a variety of extensions including optimal stabilization policy price indexation endogenous and statedependent price stickiness capital formation model uncertainty and downward nominal wage rigidities on the normative side price level targeting delivers large welfare gains and a very low optimal inflation rate consistent with price stability these results suggest that raising the inflation target is too blunt an instrument to efficiently reduce the severe costs of zero bound episodes

monetary and fiscal policy interactions in a micro founded model of a monetary union abstract this paper analyzes in detail the mechanisms behind fiscal stabilization policy and the role of policy commitment in a micro founded new keynesian model of a two country monetary union which is hit by supply shocks we also explore the determinants of the gains from fiscal stabilization while monetary policy with identical union members is concerned with stabilizing the union wide economy fiscal policy aims at stabilizing inflation differences and the terms of trade besides exploring optimal policies we also consider monetary and fiscal rules we study these rules both under coordination and non coordination by the fiscal authorities

discretionary behavior with respect to allowances for loan losses and the behavior of security prices abstract the study examines the capital market pricing of discretionary and nondiscretionary components of a major accrual in the banking industry the allowance for loan losses the analysis employs a two stage approach in which the allowance account is first decomposed into estimates of its nondiscretionary and discretionary components the second stage evaluates the market s valuation of the estimates of the components evidence suggests that the capital market perceives the allowance to be comprised of two components a nondiscretionary component which is negatively priced and a discretionary component whose incremental pricing coefficient is positive

heterogeneous expectations in monetary dsge models this paper derives a general new keynesian framework with heterogeneous expectations by explicitly solving the micro foundations underpinning the model the resulting reduced form is analytically tractable and encompasses the representative rational agent benchmark as a special case we specify a setup in which some agents as a result of cognitive limitations make mistakes when forecasting future macroeconomic variables and update their beliefs as new information becomes available while other agents have rational expectations we then address determinacy issues related to the use of different interest rate rules and derive policy implications for a monetary authority aiming at stabilizing the economy in a dynamic feedback system in which macroeconomic variables and heterogeneous expectations co evolve over time

exchange rate volatility international trade and the value of exporting firms abstract increased exchange rate volatility positively affects the value of exporting firms via the price and volume impacts of exchange rates and also makes an exporting strategy more attractive relative to the direct investment investment in export production capacity could therefore be a positive function of exchange rate volatility firms would also be more willing to sustain losses i e to engage in dumping before they abandon their export markets the effect on the volume and value of trade is ambiguous

investment and demand uncertainty this paper investigates the effects of uncertainty on the investment decisions of a sample of italian manufacturing firms using information on the subjective probability distribution of future demand for firms products according to the entrepreneurs the results support the view that uncertainty weakens the response of investment to demand thus slowing down capital accumulation consistent with the predictions of the theory there is considerable heterogeneity in the effect of uncertainty on investment it is stronger for firms that cannot easily reverse investment decisions and for those with substantial market power we show that the negative effect of uncertainty on investment cannot be explained by uncertainty proxying for liquidity constraints

international financial volatility and commodity exports evidence from the thai agricultural sector using 1981 2006 data from the bank of thailand i estimate the effect of four measures of real exchange rate volatility on thai exports of five key agricultural commodities controlling for both the level of the real exchange rate and foreign incomes estimates of the effect of volatility on export volume are generally negative and often significant lending support to a range of theoretical models that predict such an effect no such relationship exists between lagged values of exchange rate volatility and agricultural production the range of results obtained using various measures of volatility suggests caution in comparing studies using different measures copyright 2010 oxford university press

exchange rate volatility and exports a firm level analysis the relationship between real exports and exchange rate volatility is investigated using panel data analysis at the firm level results indicate that there is no negative or positive relationship between volatility and real exports in addition firm size and level of international activity do not influence the size and significance of the volatility effect on exports however there is some evidence that firms use import revenue to lower their exchange rate exposure

does exchange rate stability increase trade and welfare we develop a simple general equilibrium framework to study the effect of the exchange rate system on trade and welfare an important feature of the model is deviations from purchasing power parity caused by rigid price setting in buyers currency we find the following first exchange rate stability is not necessarily associated with more trade in a simple benchmark model with separable preferences and only monetary shocks trade is unaffected by the exchange rate system consistent with most evidence second both trade and welfare can be higher under either exchange rate system depending on preferences and on the monetary policy rules followed under each system finally in general there is no one to one relationship between the levels of trade and welfare across exchange rate systems

investments and uncertainty revisited the case of the us economy this article examines the relationship between investments and uncertainty for the us economy as the latter is approximated by consumer sentiment purchasing managers prospects and economic polic

non discretionary conservatism evidence and implications a large body of accounting research finds that various contracting incentives lead managers to engage in conservative accounting practices we extend existing research by modeling the impact of extant accounting rules on conservative accounting accounting rules typically require assets to be written down when their fair values drop sufficiently below their book values we document evidence of the resulting non discretionary conservatism and show that it appears to explain some of the results from previous research on contracting incentives

exchange rate variability and the level of international trade abstract theoretical research has shown that under reasonable assumptions exchange rate variability ought to depress the level of trade this paper builds a theoretical model designed to exaggerate the negative effect of exchange rate variability on trade in order to calibrate an upper bound to the potential size of this effect numerical analysis demonstrates that exchange rate variability of the magnitude currently observed among industrial countries has an insignificant effect on the level of trade this result is robust with respect to a wide range of parameter values and with respect to reasonable extensions of the model

uncertainty and export performance evidence from 18 countries we study a sample of nine developed and nine developing countries to evaluate the questions of how foreign income uncertainty and real exchange rate rer uncertainty impact international trade and how those impacts vary according to stage of development rer uncertainty has a negative and significant impact on export growth for six of the nine less developed countries in our sample while it has an insignificant effect for a majority of the developed countries in both groups foreign income uncertainty has a more pervasively significant and frequently larger influence on trade than does rer uncertainty

monetary instability the predictability of prices and the allocation of investment an empirical investigation using u k panel data it is often argued that monetary instability reduces the informational content of market signals and thereby hinders the efficient allocation of investment in this paper we use a signal extraction framework to give empirical content to this idea in particular we show why this framework predicts that as monetary uncertainty decreases the cross sectional distribution of investment widens we then explore this hypothesis using panel data information for uk companies over twenty years our data generally support the view that monetary instability may affect investment allocation through its effect on the predictability of prices this abstract was borrowed from another version of this item

has exchange risk depressed international trade the impact of third country exchange risk abstract this paper argues that the effect of exchange risk on bilateral and aggregate trade flows should be analyzed by including the impact of third country exchange risk factors in addition to direct bilateral or multilateral risk after a theoretical examination of these effects us bilateral export flow to its six largest trading partners are analyzed empirically i find individuality and jointly significant third country risk effects in most cases in contrast to some recent bilateral efforts i find a steadily growing negative impact on trade flows from exchange risk during floating and in contrast to recent aggregate trade flow studies i conclude that there was no temporary decline in exchange risk during the late 1970s

investment irreversibility and financing constraints evidence from a panel of transition economies abstract focusing on a panel of unlisted firms from transition economies we observe that only firms facing low irreversibility exhibit high and significant investment cash flow sensitivities our findings provide a new explanation for why some financially constrained firms may exhibit low sensitivities

why are losses less persistent than profits curtailments vs conservatism it is well documented that losses are less persistent than profits and that stock prices anticipate the lower persistence of losses yet the underlying explanation for these results is unclear one explanation lies in the abandonment option whereby firms with losses are more likely to curtail operations e g hayn hayn c 1995 the information content of losses j accounting econom 20 2 125 153 another explanation involves timely loss recognition stemming from conservative accounting e g basu basu s 1997 the conservatism principle and the asymmetric timeliness of earnings j accounting econom 24 1 3 37 we provide direct evidence that curtailments are an important factor contributing to the lower persistence of losses an implication of our results is that popular measures of conservatism such as the measure proposed by basu also reflect curtailments this paper was accepted by suraj srinivasan accounting

economic policy uncertainty and the supply of business loans abstract using a vector autoregressive framework of analysis we show that banks contract their supply of business credit in response to an exogenous increase in economic policy uncertainty this contraction takes two main distinct forms on the one hand banks restrict their supply of spot funds which we document using flows of loans and term loan originations on the other hand banks also curtail their provision of liquidity insurance reducing the amount of new credit lines and embedding in them a pricing structure that reduces the probability of borrowers drawing down on the lines at the peak of the responses we find that a one standard deviation increase in epu causes a contraction in the supply of business loans between 3 and 5 on the extensive margin

have we underestimated the likelihood and severity of zero lower bound events prior to the financial crisis most economists probably did not view the zero lower bound zlb as a major problem for central banks using a range of structural and statistical models we find that previous research understated the zlb threat by ignoring uncertainty about model parameters and latent variables focusing too much on the great moderation experience and relying on structural models whose dynamics cannot generate sustained zlb episodes our analysis also suggests that the federal reserve s asset purchases while materially improving macroeconomic conditions did not prevent the zlb constraint from having first order adverse effects on real activity and inflation
