inefficient credit booms this paper studies the welfare properties of competitive equilibria in an economy with financial frictions hit by aggregate shocks in particular it shows that competitive financial contracts can result in excessive borrowing ex ante and excessive volatility ex post even though from a first best perspective the equilibrium always displays under borrowing from a second best point of view excessive borrowing can arise the inefficiency is due to the combination of limited commitment in financial contracts and the fact that asset prices are determined in a spot market this generates a pecuniary externality that is not internalized in private contracts the model provides a framework to evaluate preventive policies which can be used during a credit boom to reduce the expected costs of a financial crisis copyright 2008 wiley blackwell

the federal funds rate and the channels of monetary transmission the authors show that the interest rate on federal funds is extremely informative about future movements of real macroeconomic variables then they argue that the reason for this forecasting success is that the funds rate sensitively records shocks to the supply of bank reserves that is the funds rate is a good indicator of monetary policy actions finally using innovations to the funds rate as a measure of changes in policy the authors present evidence consistent with the view that monetary policy works at least in part through credit i e bank loans as well as through money i e bank deposits copyright 1992 by american economic association

a liquidity based model of security design we consider the problem of the design and sale of a security backed by specified assets given access to higher return investments the issuer has an incentive to raise capital by securitizing part of these assets at the time the security is issued the issuer s or underwriter s private information regarding the payoff of the security may cause illiquidity in the form of a downward sloping demand curve for the security the severity of this illiquidity depends upon the sensitivity of the value of the issued security to the issuer s private information thus the security design problem involves a tradeoff between the retention cost of holding cash flows not included in the security design and the liquidity cost of including the cash flows and making the security design more sensitive to the issuer s private information we characterize the optimal security design in several cases we also demonstrate circumstances under which standard debt is optimal and show that the riskiness of the debt is increasing in the issuer s retention costs for assets

from cash in the market pricing to financial fragility we review some recent research that explores the relationship between asset price volatility and financial fragility when markets and contracts are incomplete jel e5 g2

debt and seniority an analysis of the role of hard claims in constraining management we argue that long term debt has a role in controlling management s ability to finance future investments a company with high widely held debt will find it hard to raise capital since new security holders will have low priority relative to existing creditors conversely for a company with low debt we show there is an optimal debt equity ratio and mix of senior and junior debt if management undertakes unprofitable as well as profitable investments we derive conditions under which equity and a single class of senior long term debt work as well as more complex contracts for controlling investment behavior

leverage cycles and the anxious economy ing opportunities for emerging economies their access to international markets has turned out to be very volatile with frequent periods of market closures even worse as we will show emerging economies with sound fundamentals are the ones that issue less debt during these closures the goal of this paper is to present a theory of asset pricing that will shed light on the problems of emerging assets like emerging markets that are not yet mature enough to be attractive to the general public their marginal buyers are liquidity constrained investors with small wealth relative to the whole economy who are also marginal buyers of other risky assets we will use our theory to argue that the periodic problems faced by emerging asset classes are sometimes symptoms of what we call a global anxious economy rather than of their own fundamental weaknesses

the effectiveness of structural adjustment lending initial evidence from malawi abstract the world bank s new programs of structural adjustment lending are likely to prove most effective with those governments which demonstrate shared ideals in their approach to economic adjustment and policy reform malawi has long been regarded as a country placing great reliance on the market in resource allocation showing restraint in public sector expansion and retaining a strong export orientation the balance of payments difficulties and the deterioration in economic circumstances which began in 1980 did not arise solely from external shocks but the structural adjustment lending programs introduced in 1981 as a means of easing the painful reform process found root in a fertile and responsive policy environment this paper chronicles the first two sals to malawi reviewing in particular the specific policy reforms advocated and required by the bank the extent of their implementation and the provisional effects on the malawi economy

financial intermediaries and liquidity creation trading losses associated with information asymmetries can be mitigated by designing securities which split the cash flows of underlying assets these securities which can arise endogenously have values that do not depend on the information known only to informed agents bank debt deposits is an example of this type of liquid security which protect relatively uninformed agents and we provide a rationale for deposit insurance in this content high grade corporate debt and government bonds are other examples implying that a money market mutual fund based payments system may be an alternative to one based on insured bank deposits

how the world achieved consensus on monetary policy the worldwide progress in monetary policy is a great achievement and especially considering the situation 30 years ago a remarkable success story i describe how the world achieved a working consensus on the core principles of monetary policy by the late 1990s i survey the muddled state of affairs in the 1970s and then ask what happened in federal reserve policy to produce an understanding of the practical principles of monetary policy how did formal institutional support for targeting low inflation abroad follow from an international acceptance of these ideas and how did a consensus theoretical model develop in academia i explain how the modern theoretical consensus known alternatively as the new neoclassical synthesis or the new keynesian model of monetary policy reinforces key advances the priority for price stability the targeting of core rather than headline inflation the importance of credibility for low inflation and preemptive interest rate policy supported by transparent objectives and procedures of course a working consensus does not constitute complete agreement accordingly the conclusion identifies important monetary policy issues that remain to be explored

crude awakening behind the surge in oil prices the first few months of 2008 saw crude oil prices breach one barrier after another they topped 100 a barrel for the first time on feb 19 then rose past 103 76 about two weeks later surpassing the previous inflation adjusted peak established in 1980 in april and early may oil prices pushed past 110 and then 120 a barrel and beyond these milestones reflect a new era in oil markets after the tumult of the early 1980s prices remained relatively tame for two decades in both real and nominal terms this long stretch of stability ended in 2004 when oil topped 40 a barrel for the first time then embarked on a steep climb that continued into this year modern economies run on oil so it s important to understand how recent years with their surging prices differ from the preceding two decades a good starting point is strong demand which has pushed world oil markets close to capacity new supplies haven t kept up with this demand fueling expectations that oil markets will remain tight for the foreseeable future a weakening dollar has put upward pressure on the price of a commodity that trades in the u s currency and because a large share of oil production takes place in politically unstable regions fears of supply disruptions loom over markets these factors have fed the steady sometimes swift rise of oil prices in recent years their persistence suggests the days of relatively cheap oil are over and the global economy faces a future of high energy prices how they play out will shape oil markets and determine prices for years to come

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

liquidity provision banking and the allocation of interest rate risk abstract the paper studies the efficient allocation of technology induced interest rate risk and the implications of such risk for efficient liquidity provision complete immunization against interest rate risk is shown to be undesirable as it precludes the exploitation of favourable reinvestment opportunities under the assumptions of diamond dybvig 1983 interest induced valuation risks of long term assets should be born by early withdrawers reinvestment opportunity risks of short term assets by late withdrawers efficient liquidity provision thus entails no shifting of interest rate risk in the absence of additional moral hazard second best allocations can be implemented through unregulated competition among banks

externalities in economies with imperfect information and incomplete markets this paper presents a simple general framework for analyzing externalities in economies with incomplete markets and imperfect infonnation by identifying the pecuniary effects of these externalities that net out the paper simplifies the problem of determining when tax interventions are pareto improving the approach indicates that such tax interventions almost always exist and that equilibria in situations of imperfect information are rarely constrained pareto optima it can also lead to simple tests based on readily observable indicators of the efficacy of particular tax policies in situations involving adverse selection signaling moral hazard incomplete contingent claims markets and queue rationing equilibria traditional discussions of externalities have emphasized the distinction between technological externalities in which the action of one individual or firm directly affects the utility or profit ofanother and pecuniary externalities in which one individual s or firm s actions affect another only through effects on prices while the presence of technological externalities imply in general that a competitive equilibrium may not be pareto efficient pecuniary externalities hy themselves are not a source of inefficiency the fact that prices change has of course important consequences there are both distributional and allocational effects but the distribution effects net out gains for example hy firms whose prices increase are precisely offset by losses e g to individuals who must pay higher prices and there are no welfare losses from the allocation effects as long as the price changes involved are small if firms are maximizing profits and individuals are maximizing utility both facing prices that correctly refiect opportunity costs then standard envelope theorem arguments imply that changes in profits or utility induced by changes in allocations resulting from any small change in prices are negligible

monetary policy as financial stability regulation this paper develops a model that speaks to the goals and methods of financialstability policies there are three main points first from a normative perspective the model defines the fundamental market failure to be addressed namely that unregulated private money creation can lead to an externality in which intermediaries issue too much short term debt and leave the system excessively vulnerable to costly financial crises second it shows how in a simple economy where commercial banks are the only lenders conventional monetary policy tools such as open market operations can be used to regulate this externality while in more advanced economies it may be helpful to supplement monetary policy with other measures third from a positive perspective the model provides an account of how monetary policy can influence bank lending and real activity even in a world where prices adjust frictionlessly and there are other transactions media besides bank created money that are outside the control of the central bank

incorporation and exclusion the life cycle of malawi s refugee assistance program abstract the dynamics of institutional relationships in assistance provision to 1 2 million mozambican refugees in malawi are examined three phases are identified an innovative model of assistance delivery integrating refugees and hosts in a development orientated program was established in the early phases this avoided the parallel structures of orthodox relief operations within the context of its political economy the government of malawi successfully mediated competing interests incrementally the host government lost autonomy this is explained in terms of pressures to internationalize and diversify the program and the adoption of a conventional relief model focusing only on refugees and emergency assistance with extensive repatriation the program is winding down the lessons learned are discussed

presidential address asset price dynamics with slow moving capital i describe asset price dynamics caused by the slow movement of investment capital to trading opportunities the pattern of price responses to supply or demand shocks typically involves a sharp reaction to the shock and a subsequent and more extended reversal the amplitude of the immediate price impact and the pattern of the subsequent recovery can reflect institutional impediments to immediate trade such as search costs for trading counterparties or time to raise capital by intermediaries i discuss special impediments to capital formation during the recent financial crisis that caused asset price distortions which subsided afterward after presenting examples of price reactions to supply shocks in normal market settings i offer a simple illustrative model of price dynamics associated with slow moving capital due to the presence of inattentive investors i address the implications for asset price dynamics of the apparent slow movement of investment capital to trading opportunities the arrival of new capital to an investment opportunity can be delayed by fractions of a second in some markets for example an electronic limit order book market for equities or by months in other markets such as that for catastrophe risk insurance accordingly prices respond to supply or demand shocks with a sharp reaction because of the relatively small subset of capital and thus risk bearing capacity that is immediately available to absorb a shock on short notice such a price impact is substantially reversed over time as additional capital becomes available the amplitude of the immediate price impact and the pattern of the subsequent recovery can reflect many sorts of attention costs to trade as well as institutional impediments to capital movement such as search costs for trading

the politics of government ngo relations in africa abstract non governmental organizations ngos deservedly or not have gained a reputation as the leading practitioners of rural development in africa african governments have responded ambiguously to the presence of these new agencies on the one hand valuing the economic resources ngos can raise but resisting the political pluralization implied by popular development action this article describes the growth of ngos in africa and proposes a framework for analyzing the dynamics of government ngo relations by means of examples drawn from kenya and zimbabwe among other african countries the article illustrates the strategies used by governments to exercise control and by ngos to assert autonomy an argument is made that politics rather than economics best explain the contribution of ngos to development as well as the attitude of governments toward the burgeoning voluntary sector

excessive dollar debt financial development and underinsurance we propose that the limited financial development of emerging markets is a significant factor behind the large share of dollar denominated external debt present in these markets we show that when financial constraints affect borrowing and lending between domestic agents agents undervalue insuring against an exchange rate depreciation since more of this insurance is present when external debt is denominated in domestic currency rather than in dollars this result implies that domestic agents choose excessive dollar debt we also show that limited financial development reduces the incentives for foreign lenders to enter emerging markets the retarded entry reinforces the underinsurance problem

who borrows from the lender of last resort understanding why banks borrow from the lender of last resort lolr during a nancial crisis is crucial to understanding the macroeconomic impact of such largescale interventions we document a strong divergence among banks take up of lolr assistance during the nancial crisis in the euro area as banks which borrowed heavily also used increasingly risky collateral we propose four explanations for this divergence
