the effects of monetary policy in the euro area this paper presents evidence on the monetary transmission process in the euro area based on macroeconomic data and on micro data on banks according to the estimations of macro vector autoregression and macroeconometric models a monetary policy tightening significantly reduces output and after a time lag also prices the effect on output is temporary while that on prices is permanent clear patterns of significant asymmetries in the monetary policy effects across countries do not emerge the estimations based on micro data on banks show that the main factor that determines the average bank s response to monetary policy is its degree of liquidity the lower its share of liquid assets in total assets the more strongly does a bank reduce its lending in response to a monetary tightening bank size does not emerge as an important factor for a bank s reaction to monetary policy these results hold for virtually all member countries of the european monetary union despite the differences in their banking systems copyright 2003 oxford university press

correlations between biofuels and related commodities before and during the food crisis a taxonomy perspective abstract in this paper we analyze the relationships between the prices of biodiesel ethanol and related fuels and agricultural commodities with a use of minimal spanning trees and hierarchical trees to distinguish between short term and medium term effects we construct these trees for different frequencies weekly and monthly we find that in short term both ethanol and biodiesel are very weakly connected with the other commodities in medium term the biofuels network becomes more structured the system splits into two well separated branches a fuels part and a food part biodiesel tends to the fuels branch and ethanol to the food branch when the periods before and after the food crisis of 2007 2008 are compared the connections are much stronger for the post crisis period this is the first application of this methodology on the biofuel systems

time series econometric analyses of biofuel related price volatility time series econometrics studies have analyzed volatility interactions between biofuel and food and fossil fuel markets we review data modeling techniques and the main findings in the literature and present our latest contributions we identify areas for further research

bank risk taking securitization supervision and low interest rates evidence from the euro area and the u s lending standards using a unique dataset of the euro area and the u s bank lending standards we find that low monetary policy short term interest rates soften standards for household and corporate loans this softening especially for mortgages is amplified by securitization activity weak supervision for bank capital and low monetary policy rates for an extended period conversely low long term interest rates do not soften lending standards finally countries with softer lending standards before the crisis related to negative taylor rule residuals experienced a worse economic performance afterward these results help shed light on the origins of the crisis and have important policy implications the author 2011 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

value at risk estimation with the optimal dynamic biofuel portfolio abstract in the past petroleum companies only paid attention to hedging the variation in the crude oil price and volatility however they have now expanded their analysis to encompass renewable sources such as corn and soybeans under the current low carbon biofuel obligations this paper employs garch 1 1 and arji models to estimate the one day ahead value at risk var of the optimal dynamic biofuel portfolio which consists of crude oil corn and soybeans the optimal blended standard is subject to the dual limitations of minimum production costs and the lowest biofuel using requirements our empirical findings confirm that the arji model is more suitable than the garch 1 1 model and further captures the discontinuous jump behavior from the in the sample data the results of out of sample forecasts also are represented that our models play important roles in var estimation and risk management for biofuel portfolio we therefore suggest that the petroleum companies should simultaneously pay attention to jump risk in hedging material costs in the prices of energy related crops

do banks provide financial slack we study the decision to choose bank debt rather than public securities in a firm s marginal financing choice using a sample of 500 firms over the 1980 to 1993 time period we find that firms are relatively more likely to choose bank loans when variables that measure asymmetric information problems are elevated the sensitivity of the likelihood of choosing bank debt to information problems is greater for firms with no public debt outstanding these results are consistent with the hypothesis that banks help alleviate asymmetric information problems and that firms weigh these information benefits against a wide range of contracting costs when choosing bank financing why do some firms borrow from public sources while others rely exclusively on private lenders the answer to this question is not well understood existing theories suggest that a firm must consider the tradeoff between the benefits and costs of bank debt financing relative to other potential financing choices the potential benefits of bank financing include low moral hazard and adverse selection costs and ease of renegotiation in financial distress 1 the potential costs of bank financing include monitoring costs suboptimal liquidation outcomes and distortions induced by information monopolies 2 the goal of this paper is to identify whether adverse selection problems influence a firm s choice between new bank debt public debt or common stock in particular we are interested in assessing the empirical validity of the hypothesis that banks have the ability to accurately price a firm s claims thus inducing a preference for firms that are undervalued by the market to

evaluating interval forecasts a complete theory for evaluating interval forecasts has not been worked out to date most of the literature implicitly assumes homoskedastic errors even when this is clearly violated and proceed by merely testing for correct unconditional coverage consequently i set out to build a consistent framework for conditional interval forecast evaluation which is crucial when higher order moment dynamics are present the new methodology is demonstrated in an application to the exchange rate forecasting procedures advocated in risk management

allocation effects of uncertainty on resources in japan this paper provides evidence of a negative association between macroeconomic uncertainty and the cross sectional dispersion of investment rate for a panel of japanese manufacturing firms we show that an increase in uncertainty leads to the narrowing of the cross section dispersion of investment rate and vice versa this finding suggests that firms fixed capital investment behavior becomes more homogeneous in times of increased uncertainty

estimating value at risk of crude oil price and its spillover effect using the ged garch approach estimation has been carried out using garch type models based on the generalized error distribution ged for both the extreme downside and upside value at risks var of returns in the wti and brent crude oil spot markets furthermore according to a new concept of granger causality in risk a kernel based test is proposed to detect extreme risk spillover effect between the two oil markets results of an empirical study indicate that the ged garch based var approach appears more effective than the well recognized hsaf i e historical simulation with arma forecasts moreover this approach is also more realistic and comprehensive than the standard normal distribution based var model that is commonly used results reveal that there is significant two way risk spillover effect between wti and brent markets supplementary study indicates that at the 99 confidence level when negative market news arises that brings about a slump in oil price return historical information on risk in the wti market helps to forecast the brent market conversely it is not the case when positive news occurs and returns rise historical information on risk in the two markets can facilitate forecasts of future extreme market risks for each other these results are valuable for anyone who needs evaluation and forecasts of the risk situation in international crude oil markets

do banks lend less in uncertain times we study the development of bank lending in the usa after four large jumps in uncertainty using an event study approach we find that more liquid banks slow down and lend less after a surge in uncertainty lending by smaller banks is also less responsive to increases in uncertainty which points to an increased importance of bank customer relationships for capitalization we find mixed evidence these heterogeneities across banks suggest that declines in bank lending following increases in uncertainty result at least partly from a reduced supply of bank loans

environmental quality public debt and economic development this article analyzes the consequences on capital accumulation and environmental quality of environmental policies financed by public debt a public sector of pollution abatement is financed by a tax or by public debt we show that if the initial capital stock is high enough the economy monotonically converges to a long run steady state on the contrary when the initial capital stock is low the economy is relegated to an environmental poverty trap we also explore the implications of public policies on the trap and on the long run stable steady state in particular we find that government should decrease debt and increase pollution abatement to promote capital accumulation and environmental quality at the stable long run steady state finally a welfare analysis shows that there exists a level of public debt that allows a long run steady state to be optimal

the behavior of consumer loan rates during the 1990 credit slowdown abstract this study re examines the 1990 credit slowdown by investigating the loan pricing behavior of commercial banks we find strong evidence that large undercapitalized banks contributed to the credit slowdown by charging consumers a higher than average loan rate relative to better capitalized institutions this disparity in lending exists even after accounting for bank funding costs thus we argue that there was a lending slowdown that occurred among large undercapitalized banks the reluctance to lend among undercapitalized banks is at least suggestive of behavior that is consistent with a credit crunch

strategic transparency and informed trading will capital market integration force convergence of corporate governance dominant investors can influence the publicly available information about firms by affecting the cost of information collection under strategic competition transparency results in higher variability of profits and output thus lenders prefer less transparency since this protects firms when in a weak competitive position while equity holders prefer more market interaction creates strategic complementarity in gathering information on competing firms thus entry by transparent competitors will improve price informativeness moreover as the return to information gathering increases with liquidity increasing global trading may undermine the ability of bank control to keep firms opaque

asymmetric pass through and risk of interest rate an empirical exploration of taiwan and hong kong this study employs the asymmetric threshold cointegration test suggested by enders and siklos 2001 and creates asymmetric ec egarch 1 1 m model to investigate the pass through of money market rate to banking retail rates in taiwan and hong kong it further explores the impact of interest volatility on interest rates over the period of february 1988 to december 2004 we find that the interest pass through mechanism of these two markets is noncomplete in addition based on the asymmetric threshold cointegration test we discover the existence of asymmetric cointegration relationship between retail rates and market rate in both markets in particular while employing asymmetric ec egarch 1 1 m model to test for the influence of money market rate adjustment and volatility on retail rates in short run we find robust evidence that there exist the upward rigidity in deposit rate and the downward rigidity in lending rate in both taiwan and hong kong this finding supports the hypothesis of the collusiv

comparison of historically simulated var evidence from oil prices abstract cabedo and moya cabedo j d moya i 2003 estimating oil price value at risk using the historical simulation approach energy economics 25 239 253 find that arma with historical simulation delivers var forecasts that are superior to those from garch we compare the arma with historical simulation to the semi parametric garch model proposed by barone adesi et al barone adesi g giannopoulos k vosper l 1999 var without correlations for portfolios of derivative securities journal of futures markets 19 5 583 602 the results suggest that the semi parametric garch model generates var forecasts that are superior to the var forecasts from the arma with historical simulation this is due to the fact that garch captures volatility clustering our findings suggest that cabedo and moya s conclusion is mainly driven by the normal distributional assumption imposed on the future risk structure in the garch model

the second moments matter the impact of macroeconomic uncertainty on the allocation of loanable funds abstract this paper investigates how variations in macroeconomic uncertainty distort commercial banks allocation of loanable funds by analyzing the dispersion of banks total loan to asset ratios over a quarter century period

in search for yield survey based evidence on bank risk taking abstract monetary policy can have an impact on economic and financial stability through the risk taking of banks falling interest rates might induce investment into risky activities this paper provides evidence on the link between monetary policy and bank risk taking we use a factor augmented vector autoregressive model favar for the us for the period 1997 2008 besides standard macroeconomic indicators we include factors summarizing information provided in the federal reserve s survey of terms of business lending stbl these data provide information on banks new loans as well as interest rates for different loan risk categories and different banking groups we identify a risk taking channel of monetary policy by distinguishing responses to monetary policy shocks across different types of banks and different loan risk categories following an expansionary monetary policy shock small domestic banks increase their exposure to risk large domestic banks do not change their risk exposure foreign banks take on more risk only in the mid 2000s when interest rates were too low for too long

on jumps in common stock prices and their impact on call option pricing the black scholes call option pricing model exhibits systematic empirical biases the merton call option pricing model which explicitly admits jumps in the underlying security return process may potentially eliminate these biases we provide statistical evidence consistent with the existence of lognormally distributed jumps in a majority of the daily returns of a sample of nyse listed common stocks however we find no operationally significant differences between the black scholes and merton model prices of the call options written on the sampled common stocks

debt relief and the international enforcement of loan contracts it is now apparent that the governments of many developing countries will not repay their debts as initially contracted creditors have already forgiven loans to some poor borrowers in africa loans to several middle income borrowers mostly in latin america trade in secondary markets at enormous discounts below 10 percent of face value in some cases creditors and debtors are negotiating the status of these debts with relief now likely for them as well since 1983 the situation has been seen to be sufficiently troubled to constitute a debt crisis although whether the debts actually caused the stagnation and financial chaos in many debtor countries is questionable poor economic management at home along with some adverse changes abroad probably have more to do with their plight while the debts themselves may not have caused the crisis creditors and creditor governments must now adjust to the realization that full repayment is either infeasible or that enforcing full payment is undesirable from the point of view of creditor countries as a whole the question now is what to do with these debts the baker and brady plans have increased u s government involvement in the debt crisis and have allocated public money toward its resolution the kenen plan discussed in this issue proposes still more public involvement and in all likelihood more public money each of these plans is an ad hoc response to the impasse that has arisen between some highly indebted countries and their private creditors and aspects of each plan may help resolve this impasse but none of these plans confronts the features of international capital markets that led to the crisis in the first place my argument here is that the debt crisis that began in 1983 arose from defects in how international capital markets operated the previous decade a goal of any

the international transmission of financial shocks the case of japan one of the more dramatic financial events of the late 1980s and early 1990s was the surge in japanese stock prices that was immediately followed by a very sharp decline of more than 50 percent while the unprecedented fluctuations in japanese stock prices were domestic financial shocks the unique institutional characteristics of the japanese economy produce a framework that is particularly suited to the transmission of such shocks to other countries through the behavior of the japanese banking system the large size of japanese bank lending operations in the united states enables us to use u s banking data to investigate the extent to which this domestic japanese financial shock was transmitted to the united states as well as to identify a supply shock to u s bank lending that is independent of u s loan demand we find that binding risk based capital requirements associated with the decline in the japanese stock market resulted in a decline in commercial lending by japanese banks in the united states that was both economically and statistically significant this finding has added importance given the severe real estate loan problems currently faced by japanese banks how japanese bank regulators decide to resolve these problems will have significant implications for credit availability in the united states as well as in other countries with a significant japanese bank presence

estimating multi period value at risk of oil futures prices abstractin this study we estimate the multi period value at risk var of oil future prices under a generalized autoregressive conditional heteroscedasticity with a skewed t residuals garch st model which is developed to account for the stylized facts of oil futures returns such as serial correlation volatility clustering asymmetry and heavy tails an efficient approximation algorithm based on the moment calibration method is developed to compute the multi period var and the numerical experiments show that the algorithm can yield good approximation quality in the empirical analysis we find that the garch st model can yield superior out of sample performance to a garch normal model or a garch t model especially when measuring the extreme tail risk meanwhile the square root of time rule srtr tends to underestimate the multi period tail risk and cannot produce a better performance than the garch family models

bargaining to preserve a unique ecosystem the role of anticipatory investments to establish stronger bargaining positions abstract a forester and a conservation organization bargain over the commercial exploitation or preservation of a forested tract of land with unique ecological characteristics the forester can improve its bargaining position by preparing a portion of the land for future timber production prior to negotiations between the two however doing so decreases the preservation value of the forest as well as the compensation the conservation group is willing to pay to preserve the forest the analysis suggests that the forester will begin preparing the land for timber production prior to negotiations only when the value of the land in timber production is significantly lower than the preservation values of the conservation group

debt for nature swaps as noncooperative outcomes abstract recently nongovernmental organizations have engaged in debt for nature swaps in an effort to slow the rate of deforestation the purpose of this paper is to provide analysis of the welfare properties that arise to self enforcing swaps we show that swaps may be self enforcing in that they can arise as noncooperative equilibria at high harvest and debt levels under these conditions a credit constrained ldc is likely to reduce harvest levels similarly if the ngo views preservation projects as complements it is likely to provide debt relief we provide simulations to demonstrate the effects of different parametric values for the utility functions of the ldc and ngo on the noncooperative and cooperative equilibria

biofuel related price transmission literature a review abstract in this article an extensive review of the rapidly growing biofuel related time series literature is carried out the data used the modeling techniques and the main findings of this literature are discussed providing a review of this flourishing research area is relevant as a guidepost for future research this literature concludes that energy prices drive long run agricultural price levels and that instability in energy markets is transferred to food markets

costly signal extraction and profit differentials in oligopolistic markets abstract empirical evidence indicates that there can be persistent profit differentials between firms in an industry we show that demand uncertainty and costly information acquisition by firms on market demand leads to significant profit differentials for intermediate levels of demand variability

extreme value theory and value at risk application to oil market recent increases in energy prices especially oil prices have become a principal concern for consumers corporations and governments most analysts believe that oil price fluctuations have considerable consequences on economic activity oil markets have become relatively free resulting in a high degree of oil price volatility and generating radical changes to world energy and oil industries as a result oil markets are naturally vulnerable to significant negative volatility an example of such a case is the oil embargo crisis of 1973 in this newly created climate protection against market risk has become a necessity value at risk var measures risk exposure at a given probability level and is very important for risk management appealing aspects of extreme value theory evt have made convincing arguments for its use in managing energy price risks in this paper we apply both unconditional and conditional evt models to forecast value at risk these models are compared to the performances of other well known modelling techniques such as garch historical simulation and filtered historical simulation both conditional evt and filtered historical simulation procedures offer a major improvement over the parametric methods furthermore garch 1 1 t model may provide equally good results as well as the combining of the two procedures

an ecological footprint approach to external debt relief abstract this paper applies martinez alier s environ values 2 1993 97 ecological debt concept to the problem of debt relief exploring the possibility of compensatory transfers from rich to poor countries based on existing ecological balances i employ recent estimates on ecological footprints and ecosystem values to estimate the ecological debt to be distributed among eligible transfer recipients all less developed countries ldcs the results provide a policy criterion for transfers in the event that future circumstances make large scale international debt relief compulsory the study probably underestimates the appropriate transfer amounts because of conservative assumptions regarding the environmental values and the size of the north s ecological debt in physical terms

nonlinear monetary policy in europe fact or myth abstract we hold the fort for linear specification of monetary policy and economic activity in europe using data on the last two and a half decades we cannot reject the hypothesis that monetary policy is a linear process and we find mixed results regarding economic activity

causality and predictability in distribution the ethanol food price relation revisited abstract this paper examines the relationship between biofuels field crops and cattle prices in the u s from a new perspective we focus on predictability in distribution by asking whether ethanol returns can be used to forecast different parts of field crops and cattle returns distribution or vice versa density forecasts are constructed using conditional autoregressive expectile models estimated with asymmetric least squares forecast evaluation relies on quantile weighed scoring rules which identify regions of the distribution of interest to the analyst results show that both the centre and the left tail of the ethanol returns distribution can be predicted by using field crops returns on the contrary there is no evidence that ethanol can be used to forecast any region of the field crops or cattle returns distributions

the crash of ʼ87 was it expected the evidence from options markets transactions prices of s p 500 futures options over 1985 1987 are examined for evidence of expectations prior to october 1987 of an impending stock market crash first it is shown that out of the money puts became unusually expensive during the year preceding the crash second a model is derived for pricing american options on jump diffusion processes with systematic jump risk the jump diffusion parameters implicit in options prices indicate that a crash was expected and that implicit distributions were negatively skewed during october 1986 to august 1987 both approaches indicate no strong crash fears during the 2 months immediately preceding the crash attempts to explain what caused the stock market crashes around the world in october 1987 have suffered from the paucity of major economic developments occurring around that time that could have triggered the crashes shifting expectations regarding monetary policy foreign investors fears of a dollar decline increasing riskiness of assets none of these appeared major enough if present at all to explain the magnitude of the crashes and although portfolio insurance strategies could conceivably magnify the effects of a jump in fundamentals the initiating jump in fundamentals appears to be lacking

estimating oil price value at risk using the historical simulation approach abstract in this paper we propose using value at risk var for oil price risk quantification var provides an estimation for the maximum oil price change associated with a likelihood level and can be used for designing risk management strategies we analyse three var calculation methods the historical simulation standard approach the historical simulation with arma forecasts hsaf approach developed in this paper and the variance covariance method based on autoregressive conditional heteroskedasticity models forecasts the results obtained indicate that hsaf methodology provides a flexible var quantification which fits the continuous oil price movements well and provides an efficient risk quantification

financial intermediation and delegated monitoring this paper develops a theory of financial intermediation based on minimizing the cost of monitoring information which is useful for resolving incentive problems between borrowers and lenders it presents a characterization of the costs of providing incentives for delegated monitoring by a financial intermediary diversification within an intermediary serves to reduce these costs even in a risk neutral economy the paper presents some more general analysis of the effect of diversification on resolving incentive problems in the environment assumed in the model debt contracts with costly bankruptcy are shown to be optimal the analysis has implications for the portfolio structure and capital structure of intermediaries

price stability and the ecb s monetary policy strategy abstract this paper focuses on the price stability objective within the framework of the single monetary policy strategy it starts by reviewing what this objective which is common to all central banks means second this paper focuses exclusively on the anchoring of short to medium term inflation expectations part 2 several measures show that this anchoring is effective a two pillar small structural macro economic model framework is used to analyze the impact that this anchoring of expectations has on the determination of the short to medium term inflation rate from this point of view observed inflation in the euro area seems to be in line with the theory and the ecb s action seems to be very effective third we focus on the other aspect of monetary stability the degree of price level uncertainty and the anchoring of inflation expectations in the medium to long term even though this assessment is more difficult than it is in the short to medium term since we only have a track record covering 6 years various indicators from the theoretical analysis paint a fairly reassuring picture of the effectiveness of the device used by the ecb

anxious periods and bank lending we examine the lending behavior of banks during anxious periods the main characteristic of anxious periods is that the perceptions and expectations about economic conditions worsen for economic agents even though the economy is not in a recession we identify distinct periods of anxiety for consumers ceos firms and analysts subsequently we study the lending behavior of us banks during the anxious quarters from 1985 to 2010 using bank level data the results show that banks lending falls when consumers and analysts are anxious and this effect is more pronounced when banks hold a higher level of credit risk these effects are more pronounced in anxious periods that were followed by recessions and in these periods loan growth also responds negatively to the anxiety of ceos yet these effects are quite less prevalent in the period after 2001

banks regulatory buffers liquidity networks and monetary policy transmission based on a quarterly regulatory dataset for german banks from 1999 to 2004 this paper analyzes the effects of banks regulatory capital on the transmission of monetary policy in a system of liquidity networks the dynamic panel regression results provide evidence in favor of the bank capital channel theory banks holding less regulatory capital and less interbank liquidity react more restrictively to a monetary tightening than their peers

are empirical measures of macroeconomic uncertainty alike there is a plethora of time series measures of uncertainty for inflation and real output growth in empirical studies but little is known whether they are comparable to the uncertainty measure reported by individual forecasters in the survey of professional forecasters are these two measures of uncertainty inherently distinct this paper shows that compared with many uncertainty proxies produced by time series models the use of real time data with fixed sample recursive estimation of an asymmetric bivariate generalized autoregressive conditional heteroskedasticity model yields inflation uncertainty estimates which resemble the survey measure there is however overwhelming evidence that many of the time series measures of growth uncertainty exceed the level of uncertainty obtained from survey measure our results highlight the relative merits of using different methods in modelling macroeconomic uncertainty which are useful for empirical researchers

uncertainty and cross border banking flows abstract while global uncertainty measured by the vix has proven to be a robust global push factor of international capital flows there has been no systematic study assessing the role of uncertainty in driving bilateral capital flows this paper examines the effects of higher country specific uncertainty on cross border banking flows using data from the bank for international settlements locational banking statistics the bilateral structure of this data allows disentangling supply factors from demand factors thereby helping identify the effect of higher uncertainty on cross border banking flows from other confounding factors the results of this analysis suggest that i uncertainty in a source country domestic economy is both a lender specific push and pull factor that robustly predicts a decrease in outflows cross border lending and inflows cross border borrowing ii the decline in cross border borrowing is larger than the decline in cross border lending that is the net cross border position of the banking sector increases iii despite a decline in cross border bank lending in the absolute sense the share of cross border bank lending in total bank lending increases suggesting a portfolio rebalancing iv this rebalancing occurs only when banks are lending to borrowers in advanced economies but not to those in emerging market economies

conditional jump dynamics in stock market returns this article develops a new conditional jump model to study jump dynamics in stock market returns we propose a simple filter to infer ex post the distribution of jumps this permits construction of the shock affecting the time t conditional jump intensity and is the main input into an autoregressive conditional jump intensity model the model allows the conditional jump intensity to be time varying and follows an approximate autoregressive moving average arma form the time series characteristics of 72 years of daily stock returns are analyzed using the jump model coupled with a generalized autoregressive conditional heteroscedasticity garch specification of volatility we find significant time variation in the conditional jump intensity and evidence of time variation in the jump size distribution the conditional jump dynamics contribute to good in sample and out of sample fits to stock market volatility and capture the rally often observed in equity markets following a significant downturn

market reactions to ecb policy innovations a cross country analysis abstract regulators have been paying increasing attention to governing and steering market fluctuations with their role in shaping the economic cycle being ever more crucial the combined effect of the financial and sovereign debt crises as well as the approach to the zero lower bound has made actions even more pressing forcing the european central bank to resort to unconventional instruments to revive the economies and counter deflationary pressures by using a combined event study and panel regression methodology we investigate whether european monetary union equity markets react heterogeneously to standard and non standard european central bank policy innovations our results show that conventional policies unevenly affect financial indices in the eurozone and hence are bound to generate asymmetries that reflect on real economies while unconventional measures albeit with different intensities exercise a homogeneous pressure on all markets our evidence highlights the beneficial impact of unconventional measures and suggests that they can play a useful role even in non crisis times

the social efficiency of private decisions to enforce property rights costs must be incurred if an owner is to enforce private property rights effectively we show that in a perfectly competitive economy private decisions to enforce rights may result in either more or less enforcement than is socially efficient cases of multiple stable equilibria occur and an equilibrium may be locally but not globally efficient resources may not be employed in their socially most valuable uses and enforcement may be accompanied by inefficient investment in resource productivity

on jump processes in the foreign exchange and stock markets exchange rates exhibit systematic discontinuities even after allowingfor conditional heteroskedasticity in the diffusion process the results are much more significant in theforeign exchange market than in the stock market which suggests differences in the structure of these markets finally this jump component is shown to explain some of the empirically observed mispricings in the currency options market the objective of this article is to analyze and compare the empirical distribution of returns in the stock market and in the foreign exchange market there are a number of reasons why a better understanding of the stochastic processes driving prices in these markets would be useful many financial models rely heavily on the assumption of a particular stochastic process while relatively little attention is paid to the empirical fit of the postulated distribution as a result models like option pricing models are applied indiscriminately to various markets such as the stock market and the foreign exchange market when the underlying processes may be fundamentally different the foreign exchange market for instance is characterized by active exchange rate man

understanding the accumulation of bank and thrift reserves during the u s financial crisis abstract the level of aggregate excess reserves held by u s depository institutions increased significantly at the peak of the 2007 2009 financial crisis although the amount of aggregate reserves is determined almost entirely by the policy initiatives of the central bank that act on the asset side of its balance sheet the motivations of individual banks in accumulating reserves differ and respond to the impact of changes in the economic environment on individual institutions we undertake a systematic analysis of this massive accumulation of excess reserves using bank level data for more than 7000 commercial banks and almost 1000 savings institutions during the u s financial crisis we propose a testable stochastic model of reserves determination when interest is paid on reserves which we estimate using bank level data and censored regression methods we find evidence primarily of a precautionary motive for reserves accumulation with some notable heterogeneity in the response of reserves accumulation to external and internal factors of the largest banks compared with smaller banks we combine propensity score matching and a difference in differences approach to determine whether the beneficiaries of the capital purchase program of the troubled asset relief program accumulated less cash including reserves than non beneficiaries contrary to anecdotal evidence we find that banks that participated in the program accumulated less cash including reserves than nonparticipants in the initial quarters after the capital injection

the credit crisis conjectures about causes and remedies what caused the financial crisis that is sweeping across the world what keeps asset prices and lending depressed what can be done to remedy matters while it is too early to arrive at definite answers to these questions it is certainly time to offer informed conjectures and these are the focus of this paper this abstract was borrowed from another version of this item

bank lending in uncertain times abstract we study the impact of economic uncertainty on credit supply using monthly data on more than two million corporate loan applications received by italian banks between 2004 and 2012 we find that an increase in aggregate uncertainty has two effects it lowers the likelihood that firms applications will be successful and it prolongs the time firms have to wait for their loans to be disbursed this financial acceleration mechanism varies in the cross section affecting mainly banks with low capital buffers and firms that are geographically distant from the bank to which they apply

costly monitoring loan contracts and equilibrium credit rationing this paper develops a model with asymmetrically informed agents and costly monitoring of loan contracts where an equilibrium can exhibit credit rationing borrowers are identical ex ante but some receive loans and others do not in contrast to existing credit rationing theories rationing does not occur here due to inflexible prices adverse selection or moral hazard optimizing behaviour produces a standard debt contract in equilibrium the aggregate quantity of loans and equilibrium interest rates respond differently depending on whether there is rationing in equilibrium

the great crash and the onset of the great depression this paper argues that the collapse of stock prices in october 1929 generated temporary uncertainty about future income which led consumers to forgo purchases of durable goods that the great crash generated uncertainty is evidenced by the decline in surety expressed by contemporary forecasters that this uncertainty affected consumer behavior is shown by the fact that spending on consumer durables declined drastically in late 1929 while spending on perishable goods rose slightly this effect is confirmed by the fact that there is a significant negative relationship between stock market variability and the production of consumer durables in the prewar era

estimation of value at risk for energy commodities via fat tailed garch models the choice of an appropriate distribution for return innovations is important in var applications owing to its ability to directly affect the estimation quality of the required quantiles this study investigates the influence of fat tailed innovation process on the performance of one day ahead var estimates using three garch models garch n garch t and garch ht daily spot prices of five energy commodities wti crude oil brent crude oil heating oil 2 propane and new york harbor conventional gasoline regular are used to compare the accuracy and efficiency of the var models empirical results suggest that for asset returns that exhibit leptokurtic and fat tailed features the var estimates generated by the garch ht models have good accuracy at both low and high confidence levels additionally mrsb indicates that the garch ht model is more efficient than alternatives for most cases at high confidence levels these findings suggest that the heavy tailed distribution is more suitable for energy commodities particularly var calculation

energy risk management and value at risk modeling abstract the value of energy trades can change over time with market conditions and underlying price variables the rise of competition and deregulation in energy markets has led to relatively free energy markets that are characterized by high price shifts within oil markets the volatile oil price environment after opec agreements in the 1970s requires a risk quantification value at risk has become an essential tool for this end when quantifying market risk there are various methods for calculating value at risk the methods we introduced in this paper are historical simulation arma forecasting and variance covariance based on garch modeling approaches the results show that among various approaches the hsaf methodology presents more efficient results so that if the level of confidence is 99 the value at risk calculated through hsaf methodology is greater than actual price changes in almost 97 6 percent of the forecasting period

the structure of an environmental transaction the debt for nature swap the structure and occurrence of debt for nature swaps are examined empirically contracts executing debt for nature swaps are studied to assess the role of transaction costs in determining how these agreements are structured the emerging contract form is a product of weak enforcement of legal claims to environmental resources in developing countries high costs for delineating and monitoring environmental outcomes and nominal government ownership of the resources involved the occurrence of swaps in individual countries is significantly related to host country attributes including the presence of tropical land and threatened species democratic political institutions and large debt burdens

the cross country impact of ecb policies asymmetries in asymmetries out abstract since its inception the adequacy of the eurozone to be an optimal currency area has been questioned and along with it the homogeneous transmission and impact of the monetary impulses across the member countries we provide a comprehensive assessment of the transmission mechanism s functioning its symmetry impact on target variables and evolution addressing all the questions which have remained unanswered in the previous literature while adding evidence on the impact of non standard policy measures we do so by adopting a bayesian time varying parameters favar model that fixes the flaws present in past research the empirical analysis shows that the occurrence of the two crises significantly altered policy transmission with both the interest rate and credit channel being consistently affected it also shows that while they provided effective stimuli to the economies the unconventional measures implemented were not able to fix those asymmetries policy wise our findings suggest that authorities must push towards consistent innovation on the fiscal side while gaining more confidence with regards to the new monetary toolkit

market risk in commodity markets a var approach we put forward value at risk models relevant for commodity traders who have long and short trading positions in commodity markets in a 5 year out of sample study on aluminium copper nickel brent crude oil and wti crude oil daily cash prices and cocoa nearby futures contracts we assess the performance of the riskmetrics skewed student aparch and skewed student arch models while the skewed student aparch model performs best in all cases the skewed student arch model delivers good results and its estimation does not require non linear optimization procedures as such this new model could be relatively easily integrated in a spreadsheet like environment and used by market practitioners

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

the benefits of lending relationships evidence from small business data this paper empirically examines how ties between a firm and its creditors affect the availability and cost of funds to the firm we analyze data collected in a survey of small firms by the small business administration the primary benefit of building close ties with an institutional creditor is that the availability of financing increases we find smaller effects on the price of credit attempts to widen the circle of relationships by borrowing from multiple lenders increases the price and reduces the availability of credit in sum relationships are valuable and appear to operate more through quantities rather than prices

aggregate volatility and international dynamics the role of credit supply abstract changes in country specific aggregate volatility are positively correlated with the current account but negatively correlated with investment output and credit flows an international real business cycle model with time varying aggregate uncertainty through a precautionary savings channel can account for the positive correlation but implies counterfactual comovements for the other variables adding a credit supply channel with default and lenders exposed to aggregate risk allows the model to match all the facts higher volatility contracts credit supply and lowers investment and output the current account turns to a surplus because savings increase but also because investment collapses

the relationship between net interest margin and noninterest income using a system estimation approach abstract this paper examines the determinants of bank net interest margin nim and non traditional banking activities nii a system estimation approach is employed to control for the simultaneity between nim and nii for commercial banks in a group of 28 financially liberalized countries during the period between 1997 and 2004 we find a statistically significant negative relationship between nim and nii for the period between 1997 and 2002 a generally positive but statistically insignificant association between nim and nii is found for the subsequent period 2003 2004 banks increasing involvement in non traditional activities is negatively correlated with risk adjusted profitability measures in the former subperiod suggesting no obvious diversification benefits however the share of noninterest income is positively related to the return on assets roa and the return on equity roe for the latter subsample

some evidence on the empirical significance of credit rationing this paper examines the credit rationing debate using detailed contract information on over one million commercial bank loans from 1977 to 1988 while commercial loan rates are sticky consistent with rationing this stickiness varies with loan contract terms in ways that are not predicted by equilibrium credit rationing theory in addition the proportion of new loans issued under commitment does not increase significantly when credit markets are tight despite the fact that borrowers without commitments can be rationed whereas commitment borrowers are contractually insulated from rationing overall the data suggest that equilibrium rationing is not a significant macroeconomic phenomenon

bank systemic risk and macroeconomic shocks canadian and u s evidence abstract this paper investigates how banks as a group react to macroeconomic risk and uncertainty more specifically it examines the relationship between bank systemic risk and changes and disruptions in economic conditions adopting the methodology of beaudry et al 2001 we introduce a new estimation procedure based on egarch to refine the framework developed by baum et al 2002 baum et al 2004 baum et al 2009 and quagliariello 2007 quagliariello 2009 and we analyze the relationship in the current industry context i e in the context of market based banking our results confirm that banks tend to behave more homogeneously vis a vis macroeconomic uncertainty in particular we find that both the cross sectional dispersion of loans to assets and the cross sectional dispersion of non interest income share shrink during slow growth episodes and particularly during financial crises when the resilience of the banking system is at its lowest more importantly our main findings indicate that the cross sectional dispersion of loans to assets has increased in the last decade whereas the cross sectional dispersion of non interest income share appears to be more volatile and sensitive to macroeconomic shocks

event studies in economics and finance the event study is an important research tool in economics and finance the goal of an event study is to measure the effects of an economic event on the value of firms event study methods exploit the fact that given rationality in the marketplace the effects of an event will be reflected immediately in security prices thus the impact can be measured by examining security prices surrounding the event in this paper event study methods are described including some of the potential complications an example is included to illustrate the approach

car mechanics in the lab investigating the behavior of real experts on experimental markets for credence goods credence goods such as car repairs or medical services are characterized by severe informational asymmetries between sellers and consumers leading to fraud in the form of provision of insufficient service undertreatment provision of unnecessary service overtreatment and charging too much for a given service overcharging recent experimental research involving a standard student subject pool has examined the influence of informational and market conditions on the type and level of fraud we investigate whether professional car mechanics as real sellers of credence goods react in the same way to changes in informational and institutional constraints while we find qualitatively similar effects in the fraud dimensions of undertreatment and overcharging for both subject pools car mechanics are significantly more prone to supplying unnecessary services in all conditions which could be a result of decision heuristics they learned in their professional training
