do the foreign exchange rates really follow a random walk an empirical question revisited abstract the random walk behavior of nominal exchange rates using daily weekly and monthly data and of real exchange rates using monthly data is investigated for seven major currencies and fails to be confirmed but fails less frequently for the post 1979 period

evidence on growth increasing returns and the extent of the market if economic growth relies upon the extent of the market then openness will decrease the connection between initial income and later growth alternatively learning by doing models suggest that wealth will be more positively correlated with growth in open economies because trade causes advanced economies to specialize in products with more opportunities for learning we examine twentieth century less developed countries and nineteenth century u s states in both data sets there is a much stronger correlation between growth and initial wealth among closed economies these findings support the importance of the extent of the market and aggregate demand in fostering growth

mean reversion in real exchange rates evidence and implications for forecasting abstract the stationarity of real exchange rates over the recent flexible exchange rate period is an issue that has long bedeviled researchers in international finance using a constrained multivariate framework this paper provides the strongest evidence yet that real exchange rates were mean reverting over the 1973 93 period we also investigate shifts in long run real exchange rates which may be important for the purpose of forecasting out of sample forecasting shows that the random walk model is outperformed by a mean stationary model especially at long horizons in addition there are substantial forecasting benefits from using a multivariate approach

credit lines and credit utilization while much is known about the characteristics of consumers or businesses that obtain credit lines relatively little is known empirically about credit line utilization after origination this study fills that gap by testing two interrelated hypotheses concerning borrower credit quality and credit line utilization the empirical analysis confirms that borrowers with higher expectations of future credit quality deterioration originate credit lines to preserve financial flexibility furthermore we estimate a competing risks model that confirms our predictions concerning changes in borrower credit line utilization in response to borrower credit quality shocks

forecasting foreign exchange rates with an intrinsically nonlinear dynamic speed of adjustment model forecasting foreign exchange rates is an important but difficult process therefore it is important to use a superior forecasting model the paper takes up this criterion and proposes to describe and forecast foreign exchange rates by developing an intrinsically nonlinear model with variable and dynamic speeds of adjustment it is found that the speed of adjusting the random or expected to the equilibrium rate is very slow implying that fiscal policy statistically insignificat and monetary policy statistically significant may be ineffective to induce changes in the adjustment speed we also find that the nonlinear dynamic model improves forecasting performance implying that nonlinearities in the sense of functional forms are exploitable for improved point forecasting of foreign exchange rates

robust tests for unit roots in the foreign exchange market abstract empirical studies that have tested for unit roots in foreign exchange rate data have assumed independent and identically distributed errors in order to apply dickey fuller test procedures this assumption ignores the temporal dependence of the error sequence present in many simple efficient market tests as discussed in hansen and hodrick 1980 as well as krasker 1980 in this paper we apply unit root test statistics that allow for heterogeneously distributed and mildly dependent error processes and thus provide superior tests of the unit root hypothesis in the case of foreign exchange rates

deviations from purchasing power parity in the long run this paper demonstrates that deviations from purchasing power parity reveal a remarkable and possibly startling consistency with martingale behavior during both fixed and flexible rate periods for a wide variety of countries and in both monthly and annual data since this pattern appears to be much more general than one would expect on the basis of models founded on international commodity arbitrage the paper proposes an alternative explanation which instead relies on financial arbitrage in bonds as the underlying mechanism this paper will demonstrate that deviations from purchasing power parity ppp reveal a remarkable and possibly startling consistency with martingale behavior during both fixed and flexible exchange rate periods for a wide variety of countries and in both monthly and annual data this pattern appears to be much more general than one would expect on the basis of models founded on international commodity arbitrage the paper therefore proposes an alternative explanation which does not presuppose free trade in goods but which instead relies on financial arbitrage in bonds as the underlying mechanism the major implication of the theory and the results is that ppp is as likely to be violated in the long as in the short run as an empirical matter deviations from ppp can be observed for most currencies at any instant see kravis et al 21 stockman 37 and genberg 15 among others these deviations are typically both cumulative and persistent the real exchange rate can remain on either side of parity for lengthy but variable time intervals of a year or more as a consequence the current consensus shared

national price levels purchasing power parity and cointegration a test of four high inflation economies abstract the time series properties of exchange rates and wholesale prices from four high inflation countries show some evidence in support of purchasing power parity tests for stationarity of real exchange rates and cointegration among price and exchange rate variables are presented for argentina brazil chile and israel during the 1970s and 1980s error correction models describe the mechanism of adjustment to long run equilibrium

convergence across canadian provinces 1961 to 1991 the purpose of this study is to provide a new look at the evolution of regional disparities in canada in the light of the recent convergence studies produced by european and american economists the degree of convergence of a variety of per capita income and output measures from 1961 to today is analysed the empirical analysis suggests that there is evidence of convergence in canada for different measurements of per capita income and output since the early 1960s during this period convergence has been helped by a favorable change in terms of trade and by government transfers and taxes our estimates of the convergence speed for canadian provinces are of the same magnitude as those found for regions within the same country and across countries in european and american studies

the economics of small business finance the roles of private equity and debt markets in the financial growth cycle abstract this article examines the economics of financing small business in private equity and debt markets firms are viewed through a financial growth cycle paradigm in which different capital structures are optimal at different points in the cycle we show the sources of small business finance and how capital structure varies with firm size and age the interconnectedness of small firm finance is discussed along with the impact of the macroeconomic environment we also analyze a number of research and policy issues review the literature and suggest topics for future research

product market imperfections and loan commitments i show in a model of competitive banks that the characteristics of loan contracts are affected by product market imperfections in the borrower s industry a bank loan commitment increases the value of a borrower firm operating in an imperfectly competitive industry and thus dominates a simple loan even in the absence of risk sharing considerations and informational asymmetries between the borrower and the bank while it is individually rational for a firm to obtain a loan commitment all the firms in that industry taken together are made worse off by the existence of loan commitments a loan commitment is a contract guaranteeing future availability of credit to a borrower at a prespecified fixed or stochastic interest rate although bank loan commitments are an important financial instrument and there exists an extensive literature analyzing them the rationale for their existence is still a matter of research this paper provides an explanation for the existence of bank loan commitments to borrowers from industries in which there is imperfect competition in the product market it is shown that in such industries the option to acquire financing at predetermined rates enhances the borrower s strategic power and thus creates value for the individual borrower consider an industry with imperfect competition where firms face the problem of noncooperatively exploiting a product market opportunity the optimal product market strategy of a firm depends on the output of its rivals a firm with access to resources at a lower marginal cost than its competitors has a strategic advantage that it can exploit to gain a larger market share and profits it is shown here that a firm that does not have such a strategic advantage can create it by purchasing for a fixed initial fee an option to acquire a factor of production such as financing at favorable terms specifically by initially negotiating a bank loan commitment the firm can finance an expansion of output to meet a strategic contingency at more favorable terms than would be possible if the expansion had to be financed in the spot market the ability to exercise the commitment enables the firm to threaten its rivals strategically and moves the industry to an equilibrium more favorable to that firm thus creating value for the borrower it is shown below that it is optimal for all firms to acquire bank loan commitments altering the industry equilibrium in the process

financial contracts when costs and returns are private abstract most bank loans are made under some form of commitment contract like a line of credit we show that a commitment dominates an ordinary debt contract when investment projects have random returns that are costly to observe and random costs that are completely unobservable the fees charged on commitments reduce default risk which in turn permits larger loans than under ordinary debt contracts our results contribute to the theoretical literature on financial intermediation and square with several stylized facts about commitment contracts

competitive equilibrium in the credit market under asymmetric information abstract we study a competitive credit market equilibrium in which all agents are risk neutral and lenders a priori unaware of borrowers default probabilities admissible credit contracts are characterized by the credit granting probability the loan quantity the loan interest rate and the collateral required the principal result is that in equilibrium lower risk borrowers pay higher interest rates than higher risk borrowers moreover the lower risk borrowers get more credit in equilibrium than they would with full information no credit is rationed and collateral requirements are higher for the lower risk borrowers

an economic rationale for the pricing structure of bank loan commitments abstract an economic rationale is provided for the competitive equilibrium deployment of commitment and usage fees in loan commitment pricing it is shown that under perfect information assessing both fees rather than just one permits optimal risk sharing when the borrower is privately informed about its probability of future commitment utilization commitment and usage fees can be used to induce borrowers to identify themselves by self selection through contract choice the equilibrium characterized here is dissipative and thus raises the usual existence questions which are addressed in the paper

commercial paper bank reserve requirements and the informational role of loan commitments abstract an explanation is provided of the often observed purchase of back up bank loan commitments by corporations immediately preceding their sale of dealer placed commercial paper since loan commitments are typically viewed as hedging instruments our paper explains why a risk neutral corporation would purchase this type of instrument and how it is priced it is assumed that while firms know their own credit risks neither banks nor the paper market can distinguish between some credit applicants we show that the purchase of a commitment can identify these firms to the market the equilibrium is partially revealing of the firms with unobservable quality those with higher quality identify themselves by purchasing commitments while those with lower quality sell unbacked paper and are pooled together unbacked paper is sold also by firms whose quality is observable unidentified firms in the lowest quality range do not sell commercial paper

purchasing power parity and unit root tests using panel data abstract this paper reports the results of unit root tests for real exchange rates using a panel framework this panel approach provides greatly improved power compared to conventional univariate time series unit root tests we obtain evidence supporting ppp over the recent flexible exchange rate period for g 6 and oecd countries we show explicitly that failure to find such evidence in previous research was due to the low power of the tests

banks liquidity and the cost of liquidity to corporations we consider the liquidity shock banks experienced following the collapse of the asset backed commercial paper abcp market in the fall of 2007 to investigate whether banks liquidity conditions affect their ability to provide liquidity to corporations we find that banks that borrowed more from the federal home loan bank system or the federal reserve s discount window following that liquidity shock passed a larger portion of their borrowing costs onto corporations seeking access to liquidity when compared to the precrisis period this increase is larger among banks with a bigger exposure to the abcp market credit lines that pose more liquidity risk to banks and borrowers that are likely dependent on the credit line provider our findings show that the crisis that affected the banking system had a negative effect not only on the price of credit to corporations but also on the price corporations pay to guarantee access to liquidity

an empirical examination of long run purchasing power parity as theory of international commodity arbitrage an empirical analysis of long run purchasing power parity ppp as a theory of international commodity arbitrage between uk and us prices and the sterling us dollar exchange rate for the period 1975 1980 is presented econometric techniques concerning the cointegration of economic time series are applied to a sample of 35 manufactured commodities which in 1977 constituted approximately a quarter of the net output of all manufacturing industry in great britain our results are extremely unfavourable to the ppp hypothesis as a stable long run proportionality between exchange rates and disaggregated prices

the foreign exchange market a random walk with a dragging anchor this paper explores some anomalies in the foreign exchange market it is hard to find evidence of either short term overshooting or of longer term reversion to an equilibrium the forward exchange rate contains virtually no information on future spot rates discussions with practitioners indicate that longer term speculation based on fundamentals is strictly limited and survey data and other evidence suggest that expectations and speculation are based on a variety of models the interplay between speculation based on fundamentals and on a random walk or chartist approach influences the outcome this endorses the prior model of j a frankel and k a froot copyright 1988 by the london school of economics and political science

information reliability and a theory of financial intermediation this paper is an analysis of when it will be beneficial for agents engaged in the production of information to form coalitions the model is cast in a financial market framework thus leading to an identification of conditions sufficient for the existence of financial intermediaries intermediation is shown to improve welfare if informational asymmetries are present and the information generated to rectify these asymmetries is potentially unreliable the usual appeal to transactions costs to explain intermediation is not needed

toward a theory of bank loan commitments abstract the characteristics of fixed and variable rate bank loan commitments are analyzed in a contingent claims framework and valuation expressions are derived for these commitments the valuation expressions are used to present estimates of the impact of interest rate uncertainty on the liability assumed by a bank issuing loan commitments finally a simple two period asymmetric information model is employed to explain the recent trend among bankers to substitute variable rate commitments for their fixed rate counterparts

bank credit commitments credit rationing and monetary policy when loan needs are uncertain and bankruptcy is costly contracts resembling bank credit commitments dominate ordinary debt contracts the fees charged on commitments reduce bankruptcy risk by smoothing out borrowers loan payments reduced bankruptcy risk entitles borrowers to larger loans thereby reducing the risk of quantity rationing even if commitments reduce rationing risk monetary policy is not necessarily weaker under commitment finance a rise in lenders cost of funds perhaps reflecting a monetary contraction can reduce the expected value of a project more under a commitment than under an ordinary debt contract copyright 1994 by ohio state university press

empirical evidence on the currency carry trade 1900 2012 abstract most of the currency literature investigates the risk and return characteristics of the currency carry trade after the collapse of the bretton woods system in order to gauge the long term currency carry premium we extend the sample to 20 currencies over the period 1900 to 2012 we find modest sharpe ratios in the range of 0 2 0 4 for carry trading over this period this is markedly lower than the sharpe ratios above 0 6 reported for recent sample periods we document that carry trading occasionally incurs substantial losses which fits well with risk based explanations for deviations from uncovered interest parity we find that large carry trading losses do not necessarily coincide with large losses in global equity markets our results help to better understand the source and nature of excess returns on the carry trade

x efficiency in banking looking beyond the balance sheet the distribution free and stochastic frontier estimation methods are used to derive bank specific measures of cost and profit xefficiency this is done to investigate the importance of including aggregate measures of off balance sheet obs activities the results indicate that economic cost and production cost x efficiency estimates increase with the inclusion of the obs measure profit xefficiency estimates are largely unaffected further the composition of bankso obs activities appears to help explain interbank differences in cost and profit x efficiency estimates whereas bank size and the mix between on and off balance sheet banking activities are largely uncorrelated with the x efficiency estimates

off balance sheet activity under adverse selection the european experience abstract in the crisis that started in 2007 banks off balance sheet activity has been blamed for flooding the market with low quality assets and contributing to spreading risk throughout the economic system nevertheless this view is hardly sustainable within the context of sophisticated markets this paper puts forward an alternative interpretation of the off balance sheet market the so called adverse selection hypothesis according to this hypothesis an adverse selection problem characterizes the relation between banks and their counterparties in off balance sheet deals empirically this implies that off balance sheet activity is expected to be negatively related to failure risk whereas it is expected to be positively related to the quality of the assets used for off balance sheet operations we test the adverse selection hypothesis for a sample of banks in the 27 member countries of the european union during the pre crisis period 1996 2006 and the crisis period 2007 2009 in addition we check for possible differences between banks in the first 15 members of the european union and those in the 12 new members

political vs currency premia in international real interest differentials a study of forward rates for 24 countries abstract different approaches to quantifying the degree of capital mobility for a cross section of currencies particularly saving investment correlations and tests of real interest parity have appeared to show a surprisingly low degree of financial integration we use a new data set forward rate data for 24 countries including many small industrialized countries and seven ldcs to decompose the real interest differential into two parts the covered interest differential or political premium and the real forward discount or currency premium the latter in turn can be decomposed into the exchange risk premium and expected real depreciation we find a high degree of capital mobility across political boundaries for most of the g 11 countries plus hong kong and singapore for our sample period of 1982 to 1987 even for most of the other ldcs and smaller industrialized countries for which covered interest parity clearly fails the political premium is not as big a component of the real interest differential as the currency premium france would appear to have higher capital mobility than most by the criterion of real interest differentials but is seen in fact to have low capital mobility by the criterion of covered interest differentials a clear example of the superiority of the latter criterion

credit rationing concessionary lending and debt maturity abstract a firm raises capital for a two period investment while creditors observe the project status midstream unobservable managerial perks may consume capital each period when the firm is unfortunate early on short term financing results in either concessionary lending or costly liquidation rolling over short term debt may be problematic because the high risk premium creditors demand when asset value is low relative to debt impares managerial motivation precisely when the incentive to defer perk consumption is weakest long term financing may reduce total agency costs be enabling lenders to charge higher initial premia in effect shifting loan repayments to states in which incentive constraints are non binding

does the exchange rate follow a random walk a monte carlo study of four tests for a random walk abstract several authors have urged that real and nominal exchange rates follow a random walk conditions under which the exchange rate follows a random walk are reviewed in this paper many of these do not appear to hold therefore the empirical evidence presents a puzzle some evidence suggets the exchange rate follows a random walk while other evidence suggests the opposite should be true this paper attempts to reconcile the evidence it is argued that the tests for a random walk have low power monte carlo evidence on four tests for a random walk is presented that suppors this claim

relative ppp in the medium run abstract this paper tests the relative purchasing power parity rppp hypothesis on month by month post 1972 data and still obtains regression coefficients that are close to unity two methodological aspects have contributed to this encouraging result firstly although all rppp tests are vis a vis the usa we nevertheless exploit our a priori knowledge about the implications of these usd based equations on ppp relations between cross rates so in a sense we use all information implicit in all cross rates too secondly we selected an instrumental variable that is specifically designed to cope with lead and lag effects in non traded vs traded goods inflation our estimates indicate that most lead and lag effects seem to occur within a six month window jel f31

human capital urbanization and canadian provincial growth coulombe s 2003 human capital urbanization and canadian provincial growth reg studies 37 239 250 this paper investigates the conditional convergence of both human capital indicators and nominal per capita income across canadian provinces in a panel data empirical framework long run relative provincial steady states are determined by relative rates of urbanization one time shocks to quebec s and alberta s relative steady states and a nova scotia fixed effect indicators of relative human capital ratios appear to have converged following a pattern that is common and similar to per capita income but with two notable exceptions first in alberta the 1973 oil shock contributed to the rise in per capita income but its effect on human capital is significant only for females second human capital appears to remain concentrated in the relatively poor province of nova scotia two notable findings come out of the analysis first nominal income disparities at the provincial level appear to be real no

credible commitments contract enforcement problems and banks intermediation as credibility assurance abstract we consider contract enforceability problems in credit transactions and justify a bank as an organizational solution to market breakdown due to unenforceable contracts specifically we explain i why loan commitments exist and ii why banks exist to sell such commitments a loan commitment resolves moral hazard more efficiently than any combination of inside equity and spot credit however the market breaks down if commitment sellers are individuals because their promises to honor contracts are not credible with a large bank a perfect sequential equilibrium is obtained in which credibility is restored

competitive equilibrium with type convergence in an asymmetrically informed market this article studies an asymmetric information game with type convergence in which under some realizations of a common uncertainity inducing informed agents to reveal their types through self selection by contract choice is either costly or impossible under other realizations self selection permits costless distinctions between informed agents i obtain sufficient conditions under which contracting with options prior to the realization of the common uncertainity leads to the existence of a perfectly separating costless nash equilibrium applications to variable rate loan commitments and life insurance contracting are discussed article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

moral hazard and information sharing a model of financial information gathering agencies we propose a theory of information gathering agencies in a world of informational asymmetries and moral hazard in a setting in which true firm values are certified by screening agents whose payoffs depend on noisy ex post monitors of information quality the formation of information gathering agencies groups of screening agents is justified on two grounds first it enables screening agents to diversify their risky payoffs second it allows information sharing the first effect itself is insufficient despite the risk aversion of screening agents and the stochastic independence of the monitors used to compensate them this paper develops a model that explains the formation of financial institutions which acquire and process information for the purpose of certifying asset qualities but do not get involved in funding the model makes two basic assumptions the first is that there is an informational asymmetry in the capital market involving insiders possessing more accurate information about the true economic values of their firms than outsiders and the second is that those engaged in the production of information to rectify this asymmetry can gain from sharing their information examples of the information gathering agencies iga s we study are creditrating agencies financial newsletters standard and poor s value line investment counselors credit bureaus etc iga s are distinct from funding financial intermediaries ffi s like banks and credit unions that in addition to acquiring and processing information also issue claims against themselves fund their customers needs and transform asset characteristics from a modeling standpoint a key distinction between iga s and ffi s is that in the case of the latter outsiders depositors for instance do not necessarily have to assess the quality of the intermediary s information since the intermediary can be made accountable for this quality through the positions it takes in the screened assets thus models that explain ffi s focus on how the contracts offered by the intermediary ensure information reliability without reliance on explicit monitoring on the other hand because of the absence of loan and deposit type contracts to dissipate informational problems a model explaining iga s must rely on monitoring related mechanisms

competition risk neutrality and loan commitments abstract we rationalize fixed rate loan commitments forward credit contracting with options in a competitive credit market with universal risk neutrality future interest rates are random but there are no transactions costs borrowers finance projects with bank loans and choose ex post unobservable actions that affect project payoffs credit contract design by the bank is the outcome of a non cooperative nash game between the bank and the borrower the initial formal analysis is basically in two steps first we show that the only spot credit market nash equilibria that exist are inefficient in the sense that they result in welfare losses for borrowers due to the bank s informational handicap second we show that loan commitments because of their ability to weaken the link between the offering bank s expected profit and the loan interest rate enable the complete elimination of informationally induced welfare losses and thus produce an outcome that strictly pareto dominates any spot market equilibrium perhaps our most surprising result is that if the borrower has some initial liquidity it is better for the borrower to use it now to pay a commitment fee and buy a loan commitment that entitles it to borrow in the future rather than save it for use as inside equity in conjunction with spot borrowing

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

loan commitments investment decisions and the signalling equilibrium abstract this paper analyzes the use of loan commitments to finance future risky investment projects when the capital market is informed of a firm s project quality having a loan commitment would lead the firm to overinvest if banks are competitively rational the cost of this overinvestment would be borne by the firm making the loan commitment contract unattractive when the project quality is private information firms will signal their project qualities through purchasing loan commitments this signal is credible because purchasing a loan commitment poses overinvestment cost to the firm this paper establishes and characterizes this dissipative signalling equilibrium

market efficiency and cointegration an application to the sterling and deutschemark exchange markets abstract the assumption that the foreign exchange market is efficient that is that agents are risk neutral and use all available information rationally so that the forward exchange rate is an unbiased predictor of the future spot rate is a property often imposed in theoretical international macroeconomic models although a vast empirical literature has evolved to test market efficiency we use recent developments in the theory of cointegration to provide new methods of testing several aspects of foreign exchange market efficiency we ffind evidence inconsistent with market efficiency for both germany and the united kingdom

collateral and competitive equilibria with moral hazard and private information the authors examine equilibrium credit contracts and allocations under different competitivity specifications and explain the economic roles of collateral under these specifications both moral hazard and adverse selection are considered the principal message is that how a competitive equilibrium is conceptualized significantly affects the characterization of equilibrium credit contracts specifically some well known results in the rationing literature are shown to rest delicately on the adopted equilibrium concept two somewhat surprising results emerge first high quality borrowers with unlimited collateral may be priced out of the market despite the bank having idle deposits second high quality borrowers may put up more collateral this paper explores the allocational consequences of alternative credit market competitivity specifications and explains the different economic roles of collateral under these specifications we model banks that lend to borrowers financing projects with payoffs depending on a priori unknown borrower attributes and ex post unobservable borrower actions borrowers are assumed to have unconstrained access to collateral our analysis is based on two concepts of competitive equilibrium under both banks compete in the sense that they earn zero expected profits however under the first concept of equilibrium ti as in jaffee and russell 11 all rents accrue to borrowers whereas under the second concept t2 all rents accrue to depositors as in stiglitz and weiss 17 our research makes two main points first we demonstrate that the manner in which a competitive equilibrium is conceptualized importantly influences the characterization of equilibrium credit allocations specifically one of the findings is that the rationing equilibria of stiglitz and weiss 17 and others should be viewed as rather delicate things in that they are very sensitive to the competitivity specification used for instance

interest rates inflation and taxes the foreign connection abstract in this note it is shown that the existence of taxes on nominal interest receipts in an international setting introduces a non neutrality in that a change in expected inflation in one country must change at least one expected real interest rate or the path of the real exchange rate

some evidence on the efficiency of the sterling dollar and sterling franc forward exchange rates in the interwar period abstract we present new evidence on the time series properties of spot and forward exchange rates for the sterling dollar and sterling franc exchange rates in the interwar period unlike previous researchers we examine the stationarity of the data our results are consistent with the hypothesis that the forward rates for both currencies exhibited a time varying risk premium but that this was non stationary for the former rate and stationary for the latter

bank lending standards and access to lines of credit this paper examines how changes in bank lending standards are related to the availability of bank lines of credit for private and comparable public firms overall we find that access to lines of credit is more contingent on bank lending standards for private than for public firms the impact of bank lending standards is however asymmetric while private firms are less likely than public firms to gain access to new lines when credit market conditions are tight we find no difference between public and private firms in terms of their use or retention of pre existing lines we also find that private firms without lines of credit use more trade credit when bank lending standards are tight which is suggestive of a supply effect overall the evidence suggests that credit crunches are likely to have a disproportionate impact on private firms however pre existing banking relationships appear to mitigate the impact of these contractions on private firms

the real interest rate a multi country empirical study how real interest rates behave over time is critical to our understanding of many macroeconomic issues and much recent research has pursued this question very little of the research however has focused on real interest rates outside the united states this paper is an empirical exploration of real interest rate movements in seven oecd countries from 1967 ii to 1979 ii further research is needed on real rates in other countries for several reasons not only are measures of foreign real rates of interest in their ownright but extending an analysis of real rates to other countries also has the following additional benefits it can generate more powerful statistical tests of propositions previously tested on u s data and yield information on whether results found for the u s hold up in other countries this study pursues several questions that have arisen naturally from this earlier work is the hypothesis that the real rate is constant rejected when the analysis is extended to other countries does the real rate decline with increased inflation and money growth in other countries besides the united states how reliable is the fisher effect in which nominal interestrates reflect changes in expected inflation are movements in nominal interest rates a reliable indicator of movements in real rates what kind of variationsin real interest rates are there in different countries have real rates declined from the 60s to the 70s for other countries besides the u s this abstract was borrowed from another version of this item

flexible exchange rates prices and the role of news lessons from the 1970s recent experience with flexible exchange rate systems has led to renewed interest in the operation of foreign exchange markets as reflected in many recent studies of the principal determinants of exchange rates the 1970s witnessed the dramatic alteration of the international monetary system from a regime of pegged exchange rates which prevailed for about a quarter of a century since the bretton woods conference into a regime of flexible though managed rates as a consequence of the emergence of the new legal and economic system traders national governments and international organisations were confronted with new economic problems choices and instruments during the 1970s ex change rates fluctuated widely and inflation rates accelerated the international monetary system had to accommodate extraordinarily large oil related shocks which affected trade flows in goods and assets huge oil payments had to be recycled uncertainties concerning future developments in international politics reached new heights and the prospects for the world economy got gloomier these developments placed unprecedented pressures on the markets for foreign exchange as well as on other asset markets they were associated with a large slide in the value of the us dollar and resulted in speeding up the creation of new institutions like the european monetary system which provided the formal framework for the management of exchange rates among members

loan commitments and the debt overhang problem the debt overhang problem is shown to arise in the context of an entrepreneurial project that requires a sequence of investments financed by an outside lender the entrepreneur not internalizing losses accruing to the lender which financed the initial investments may inefficiently cancel the project and instead pursue an outside opportunity it is shown that loan commitments contracts that allow the entrepreneur to borrow a variable amount at a set interest rate in return for a fixed fee are the optimal financial contracts in this setting strictly dominating standard debt the existence of the fixed fee allows loan commitments to set a relatively low interest rate improving the entrepreneur s incentives to continue the project the paper specifies the optimal contract fully derives robust comparative statics properties using an extension of milgrom and roberts 1994 and extends the results to more realistic settings e g allowing the market risk free rate to be stochastic

investment opportunities and corporate demand for lines of credit abstract the behavior of a risk neutral corporation in selection of a line of credit is modeled in a new framework where demand for credit lines by a firm arises from the stochastic arrival in continuous time of short lived opportunities to capture investment projects the firm needs speed and secrecy to capture projects before competitors the firm chooses a credit line that balances its up front commitment cost against the expected extra cost of borrowing in the spot market upon exhaustion of its credit line the firm s demanded credit line depends upon both relative pricing within the contract and the nature of the firm s growth opportunities interestingly while credit line demand is positively related to business growth prospects it is potentially negatively related to uncertainty in those prospects

liquidation under moral hazard optimal debt maturity and loan commitments abstract this paper examines the benefits and limitations of loan commitment financing commitments enable firms to adopt more efficient liquidation policies we demonstrate however that the limitations of commitment financing depend on a number of firm characteristics in some circumstances firms find long term debt to be a superior alternative to commitment financing this provides a possible explanation for why loan commitments are not universally utilized by considering both the benefits as well as the limitations of loan commitment financing we are also able to integrate loan commitment contracts into a model of optimal debt maturity

the use of bank lines of credit in corporate liquidity management a review of empirical evidence abstract this paper reviews empirical evidence on the use of bank lines of credit as a source of corporate liquidity traditional explanation for lines of credit is that they provide insurance against liquidity shocks in much the same as way hoarding cash does however recent empirical research suggests that access to lines of credit is contingent on the credit quality of the borrower as well as the financial condition of the lender these findings suggest that lines of credit are an imperfect substitute for cash as a source of corporate liquidity

do loan commitments cause overlending i begin with a model that generates quantity credit rationing by banks in the spot credit market when the real interest rate is high and there is an economic downturn then i rationalize a bank loan commitment as partial insurance against such future rationing incorporating uncertainty about both the creditworthiness of borrowers and the abilities of banks to screen borrowers i extend the bank contracting literature wherein i examine banks decisions of whether to lend under the commitments sold earlier i show that this discretion of whether to honor borrowing requests under commitments generates reputational concerns on the part of banks and can lead to an equilibrium in which loan commitments serve their role in increasing credit supply relative to the spot credit market but produce the inefficiency of excessive credit supply when the real interest rate is low and the economy is doing well despite this welfare is higher with loan commitments than with spot credit numerous empirical predictions and policy implications are drawn out

the economics of loan commitment contracts credit pricing and utilization abstract our purpose is to examine the circumstances under which enduring customer relationships such as revolving credit agreements will become predominant we compare loan commitment contracts under which borrowers may take down funds at fixed marginal mark up to spot lending under which funds are priced in consideration of customers leverage under the first arrangement insurance against default risk is priced as a fixed front end fee under the second arrangement it is priced under a rising leverage specific markup schedule we show that when default risk is independent of take down the loan commitment contract will always dominate spot loans when default risk increases with credit use spot loans may become dominant

the commitment problem of secured lending the paper presents a new theory of trade credit in which firms buy inputs on credit from suppliers to restore the benefits of secured bank financing impaired by contract incompleteness in a setting where investment is endogenous and unobservable to financiers we show that a bank secured credit contract is time inconsistent upon being granted credit the entrepreneur has an incentive to alter the original input combination jeopardizing the bank s revenues anticipating the entrepreneur s opportunism the bank offers an unsecured credit contract reducing the surplus from the venture one way for the entrepreneur to commit to the contract terms is to purchase inputs on credit from the supplier the supplier observes the input investment and acts as a guarantor that inputs will be purchased as contracted thus facilitating access to secured bank financing the commitment role of trade credit still holds in a multi period extension that investigates the impact of bank relationship lending on secured debt and trade credit our model provides novel testable predictions on optimal financial contracts in both one period and repeated lending relationships

long run purchasing power parity during the recent float abstract this paper examines the relevance of long run purchasing power parity ppp which allows for measurement errors during the recent floating exchange rate period previous empirical studies generally fail to find support for long run ppp over this period in this paper in this paper the cointegration property of exchange rates and prices is examined using maximum likelihood procedure and we find significant evidence favorable to long run ppp further tests for symmetry and proportionality indicate that these two conditions are not generally with the data the results support the hypothesis of long run ppp with measurement errors in prices

coinsurance effect and bank lines of credit abstract the coinsurance effect hypothesis predicts that firm diversification reduces financial constraints through imperfectly correlated cash flows among segments we empirically test the hypothesis by studying the relation between coinsurance effect and bank lines of credit we find that coinsurance effect is associated with a higher availability of bank lines of credit and that diversified firms hold a higher level of bank lines of credit if they have higher investment opportunities and if they are bank dependent we find that diversified firms hold a higher fraction of corporate liquidity in the form of bank lines of credit due to the coinsurance effect the findings are consistent with the coinsurance effect hypothesis and contribute to the debate on the value consequence of firm diversification by disclosing a specific channel through which firm diversification affects financial constraints

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

commitment lending under asymmetric information theory and tests on u k startup data u k business startup data is used to examine the role of contract parameters in solving the bank s problem of lending under asymmetric information margins are found to be a direct function of the probability of failure and an inverse function of security for given loan size consistently with collateral being invoked to solve the moral hazard problem business survival is also found to be enhanced by owner equity inputs for given debt again consistent with a requirement for owner financial inputs to enhance unobservable effort security rises along with loan size and survival chances a finding consistent with a a firm loan size effect larger borrowers have lower marginal admin cost to the bank and with b positive borrower self selection better borrowers offer collateral because they are less likely to experience forfeiture observable business characteristics are found to play an important intermediary role in the solution to the moral hazard problem more mature proprietors have more experience business commitment assets for borrowing and the willingness to use them for loan collateral their contract parameters reflect these facts

persistence in foreign exchange rates abstract this study examines the long run behavior of seven daily nominal exchange rates using univariate and multivariate persistence measures our results indicate that for some currencies the long run behavior deviates from that of a pure random walk in certain periods the multivariate estimates reflect the effect of both the ems exchange rate mechanism and increased post louvre accord coordinated intervention a large portion of the effect of a shock in one currency on another currency s long run value can be attributed to contemporaneous effects on the other currencies

mean reversion in real exchange rates a modified dickey fuller test which is approximately uniformly most power invariant is employed to examine mean reversion in real exchange rates results from this test provide a wider and more significant support for mean reversion than the standard dickey fuller test

corporate cash holdings and credit line usage we investigate the factors driving the unprecedented rise in corporate liquidities since the 1970s we find that an economy wide reduction in the cost of holding liquidities and an increase in risk best explain the rise in cash holdings and the widespread use of credit lines the structural estimation results shed light on two widely acknowledged motives for holding cash the precautionary motive and the liquidity motive translate risk exposure into cash holdings our results however do not suggest that firms have become more prudent over time it is higher liquidity needs that has forced firms to hold more cash and use more credit lines abstract from author

a computational approach to pricing a bank credit line abstract using trended brownian motion to characterize borrower cash needs over time we are able to derive a probability density function for the time to depletion of a bank credit line as well as the likelihoods for the time to exhausting the sources of liquidity that fund the loan armed with these analytic results we solve for the credit line mark up rate and the configuration of stored liquidity that maximizes the bank s intertemporal expected profits from the loan the optimality conditions produce a system of integral differential equations whose solutions we then simulate over a host of scenarios

on unit roots and real exchange rates empirical evidence and monte carlo analysis this paper presents some empirical evidence that real exchange rate series contain a unit root in their time series respresentation which cancels out on first differencing using the augmented dickey fuller test the power of this test is also tested using monte carlo methods and it is found to be quite powerful against a range of stationary local alternatives the findings imply the absence of any tendency of the nominal exchange rate to converge on purchasing power parity even in the long run

some evidence on the uniqueness of initial public debt offerings debt initial public offerings ipos represent a major shift in a firm s financing policy by both extending debt maturity and altering the public private debt mix in contrast to findings for seasoned debt offerings we document a significantly negative stock price response to debt ipo announcements this result is consistent with debt maturity and debt ownership structure theories the equity wealth effect is negatively related to the offer s maturity and positively related to the degree of bank monitoring we find that firms with less information asymmetry and firms with higher growth opportunities experience a less adverse stock price response the decision to access the public debt market for the first time represents a major change in a firm s financing policy an initial public debt offer alters the firm s debt structure in two significant ways not only does this policy choice affect the firm s debt ownership structure by altering its mix of public relative to private debt but it also extends the average debt maturity of the firm substantially this study provides empirical evidence on the validity of some important debt structure theories by focusing on the information content of initial public debt offers debt ipos two major strands of theories have evolved in the literature the debt ownership choice theories model corporate choice of private and public debt mix see e g fama 1985 diamond 1991a and rajan 1992 while the other set of theories models corporate debt maturity choice easterbrook 1984 flannery 1986 and kale and noe 1990 a number of recent studies empirically test some of the predictions of these models barclay and smith 1995 guedes and opler 1996 houston and james 1996 johnson 1997 and stohs and mauer 1996

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

common stochastic trends in a system of exchange rates univariate tests reveal strong evidence for the presence of a unit root in the univariate time series representation for seven daily spot and forward exchange rate series furthermore all seven spot and forward rates appear to be cointegrated that is the forward premiums are stationary and one common unit root or stochastic trend is detectable in the multivariate time series models for the seven spot and forward rates respectively this is consistent with the hypothesis that the seven exchange rates possess one longrun relationship and that the disequilibrium error around that relationship partly accounts for subsequent movements in the exchange rates a general consensus has emerged in recent years that many macroeconomic time series such as gnp consumption expenditures disposable income etc can be characterized by a stochastic trend model in particular nelson and plosser 22 described this property as one of being difference stationary so that the first difference of a time series is stationary an alternative trend stationary model where a stationary component is added to a deterministic trend term has generally been found to be less appropriate 1 similarly it has long been recognized that many financial time series such as foreign exchange rates are nonstationary e g in meese and singleton 21 the issue of nonstationary is not merely a statistical curiosity but has several important implications for the modeling of exchange rates for instance many models of exchange rate determination under rational expectations require stationarity assumptions when solving out the expected future values of the fundamentals further there has been some controversy over the appropriate transformations to use when conducting tests of whether the forward rate is an unbiased and efficient predictor of the future spot exchange rate 2 some authors e g frenkel 11 12 have conducted tests in levels while geweke and feige 14
