the cost of market versus regulatory discipline in banking1 abstract we present evidence that insured deposit financing shields banks from the full costs of market discipline moody s downgrades indicators of increasing risk are associated with negative abnormal equity returns that are increasing in the bank s reliance on insured deposits moreover banks raise their use of insured deposits following increases in risk these findings cast doubt on the ability of capital market participants to effectively discipline bank behavior within the current regulatory environment more generally our findings highlight the potential for regulation to undermine market discipline in regulated industries

bank spread with uncertain deposit level and risk aversion abstract this paper derives a model of the banking firm under uncertainty and risk aversion the selection of the bank s optimal spread between loan and deposit rates is emphasized the model s results provide some implications for bank asset quality capital regulation and deposit insurance for example it is shown that increases in the level of equity capital tend to increase the bank s spread under dara this implies an improvement in bank asset quality on the other hand as the deposit supply function becomes more volatile the bank s spread narrows which implies a decline in the quality of the bank s assets

introducing incentives in the market for live and cadaveric organ donations we evaluate the introduction of monetary incentives in the market for live and cadaveric organ donations we show that monetary incentives would increase the supply of organs for transplant sufficiently to eliminate the very large queues in organ markets and the suffering and deaths of many of those waiting without increasing the total cost of transplant surgery by more than about 12 percent we build on the value of life literature and other parts of economic analysis to estimate the equilibrium cost of live transplants for kidneys and livers we also show that market price for kidneys will be determined by the cost of live donations even though most organs will come from cadavers

retail bank deposits as quasi fixed factors of production neoclassical models of the banking firm for example michael klein 1971 treat all deposit liabilities as fully variable factors of production banks then maximize profits minimize liability costs by equating the marginal costs of all liability types during each period the empirical relevance of these models is difficult to establish because binding deposit rate ceilings regulation q force bank competition for many retail deposits into implicit interest channels that are not readily measured it is therefore noteworthy that during two recent periods when deposit rate ceilings were not binding banks paid retail deposit rates considerably in excess of the rate at which they could borrow via large unregulated certificates of deposit such behavior seems inconsistent with the cost minimization prescribed by neoclassical bank models however if retail deposit accounts are interpreted as quasi fixed gary becker 1962 walter oi 1962 donald parsons 1972 sherwin rosen 1968 inputs to the banking firm these important historical observations can be reconciled with bank profit maximization this paper first describes two historical episodes during which the bank retail deposit rate exceeded the negotiable certificate of deposit rate for substantial periods of time while no profit maximizing cost minimizing bank would pay such a rate differential if retail deposit quantities are costlessly variable interpreting retail deposit accounts as quasi fixed inputs to the bank explains the peculiar rate structures a simple two period model of bank liability selection formalizes the analysis i two puzzling historical episodes

bank forward lending in alternative funding environments this paper examines the effects of loan commitments on bank lending behavior in both deposit funding and liability management environments assuming that the bank lends exclusively under commitments and that the number of commitments exercised is uncertain the bank must choose its supply of commitments given this choice the bank becomes a passive lender to commitment holders our focus on forward credit markets sheds new light on the private bankers assertion that they do not directly determine their level of lending but merely accommodate the credit needs of their customers similarly the central banker s claimed inability to control monetary aggregates in the short run becomes understandable in a new context it is shown that the advent of liability management will reduce the volume of loan commitments and the expected size of the bank and of the banking system it is also shown that increased uncertainty regarding borrower takedown behavior diminishes the volume of commitments expected bank and banking system size

a test of the law of one price in retail banking this paper investigates the level and the determinants of retail banking interest rate differences among spanish banks in the period 1989 2003 we find that the interest rates of twenty five different bank loan and deposit products adjust rather rapidly to their long term values in response to external shocks as the relative version of the law of one price predicts but the evidence runs contrary to the absolute version of the law credit risk premium part of the marginal cost of the loans granted by a particular bank is an important source of interest rate dispersion across banks and loan products both before and after spain joined the euro zone therefore differences in credit risk policies across banks must be taken into account when forming expectations about european retail banking integration

is global social welfare increasing a critical level enquiry abstract we assess whether global social welfare has improved in the last decades despite or because of the substantial increase in global population we use for this purpose a relatively unknown but simple and attractive social evaluation approach called critical level generalized utilitarianism clgu clgu posits that social welfare increases with population size if and only if the new lives come with a level of living standards higher than that of a critical level despite its attractiveness clgu poses a number of practical difficulties that may explain why the literature has left it largely unexplored we address these difficulties by developing new procedures for making partial clgu orderings the headline result is that we can robustly conclude that world welfare has increased between 1990 and 2005 if we judge that lives with per capita yearly consumption of more than 1 248 necessarily increase social welfare the same conclusion applies to sub saharan africa if and only if we are willing to make that same judgment for lives with any level of per capita yearly consumption above 147 otherwise some of the admissible clgu functions will judge the last two decades increase in global population size to have lowered global social welfare

how do banks respond to shocks a dynamic model of deposit taking institutions abstract this paper proposes a dynamic model of the optimal choices of a bank that benefits from market power and takes into account the impact of the deposit generation process interbank lending borrowing emerges as a buffer that assists the bank in smoothing intertemporal adjustments in interdependent loan and deposit choices the bank smooths the impact of interest rates shocks on its customers to minimize the adjustments over time of the stocks of deposits and loans it does not however provide insurance against negative shocks of real origin that increase its expected default costs the predictions of the model help to shed light on the available empirical evidence and to analyze some recent developments of the banking industry

a note on the risk adjusted price concentration relationship in banking abstract price concentration studies in banking typically find a significant and negative relationship between consumer deposit rates i e prices and market concentration this implies highly concentrated banking markets are bad for depositors it also provides support for the structure conduct performance hypothesis and rejects the efficient structure hypothesis however these studies have focused almost exclusively on supply side control variables and neglected demand side variables when estimating the reduced form price concentration relationship for example previous studies have not included in their analysis bank specific risk variables as measures of cross sectional derived deposit demand we find that when bank specific risk variables are included in the analysis the magnitude of the relationship between deposit rates and market concentration decreases by over 50 we offer an explanation for these results based on the correlation between a bank s risk profile and the structure of the market in which it operates these results suggest that it may be necessary to reconsider the well established assumption that higher market concentration necessarily leads to anticompetitive deposit pricing behavior by commercial banks this has direct implications for the antitrust evaluations of bank merger and acquisition proposals by regulatory agencies and in a more general sense these results suggest that any structure conduct performance based study that does not explicitly consider the possibility of very different risk profiles of the firms analyzed may indeed miss a very important set of explanatory variables and thus the results from those studies may be spurious

the rise of europe atlantic trade institutional change and economic growth the rise of western europe after 1500 is due largely to growth in countries with access to the atlantic ocean and with substantial trade with the new world africa and asia via the atlantic this trade and the associatedcolonialism affected europe not only directly but also indirectly by inducing institutional change where initial political institutions those established before 1500 placed significant checks on the monarchy the growth of atlantic trade strengthened merchant groups by constraining the power of the monarchy and helped merchants obtain changes in institutions to protect property rights these changes were central to subsequent economic growth

nonlinear expectations in speculative markets evidence from the ecb survey of professional forecasters chartist and fundamentalist models have proven to be capable of replicating stylized facts on speculative markets in general this is achieved by specifying nonlinear interactions of otherwise linear asset price expectations of the respective trader groups this paper investigates whether or not regressive and extrapolative expectations themselves exhibit significant nonlinear dynamics the empirical results are based on a new data set from the european central bank survey of professional forecasters on oil price expectations in particular we find that forecasters form destabilizing expectations in the neighborhood of the fundamental value whereas expectations tend to be stabilizing in the presence of substantial oil price misalignment

market evidence on the effective maturity of bank assets and liabilities the recent years increase in interest rate volatility has intensified concern over the exposure of commercial banks to interest rate or funding risk since the effect of interest rate changes on the equity value of a bank depends on the maturity or duration of the bank s assets and liabilities assessing an individual bank s interest rate risk exposure requires information about the maturity composition of its portfolio it is difficult however to assess a bank s risk exposure from balance sheet data because several important asset and liability items have theoretically ambiguous effective maturities in a frictionless market a security s effective maturity will equal its stated maturity or time to repricing with market imperfections e g depositors transaction or information costs however the equilibrium cost of some deposit items may respond sluggishly or incompletely to market rate changes see hester and pierce 1975 or flannery 1982 such liabilities market values discounted at market rates would therefore fluctuate with the level of interest rates these liabilities are sometimes called core deposits which manifest sticky responses to market rate changes we define an asset or liability s effective maturity as the maturity of a fixed rate perfectly elastically supplied security with the same market value elasticity as the bank balance sheet item under consideration naturally a balance sheet item s effective maturity is the relevant determinant of its contribution to the bank s overall interest rate risk sensitivity

profit efficiency for spanish savings banks abstract frontier profit efficiency is examined for spanish savings banks over 1986 1991 a period in which the spanish banking has seen considerable deregulation in spain the standard assumption that firms operate in a perfectly competitive output market is unlikely to be met thus we use an alternative profit function specification which allows for market power in the output market profit efficiency is determined using the thick frontier approach and estimated using both alternative and standard profit function specifications to illustrate the effect of different assumptions regarding the competitiveness of the output market estimation of the alternative profit function suggests that the profit inefficiency of spanish savings banks which averaged 28 fell by forty percent between 1986 to 1991 the standard profit function which we believe yields less reliable results generated greater average inefficiency there was no significant shift up or down in the profit frontier itself

what s different about banks abstract negotiable certificates of deposit cd s trade in the capital market in competition with other securities like commercial paper and bankers acceptances if cd s must pay lenders competitive monetary interest the reserve tax on cd s is borne by bank borrowers viability of the tax means there must be something special about bank loans that makes some borrowers willing to pay higher interest rates than those on other securities of equivalent risk moreover there must be something special about banks that prevents other intermediaries from competing to assure that it never pays to finance loans with cd s

quality quantity and duration of lives the evaluation of development processes and of public policies often involves comparisons of social states that differ in income distributions population sizes and life longevity this may require social eva luation principles to be sensitive to the quality the quantity and the duration of lives this paper 1 reviews some of the normative issues at stake 2 proposes and discusses some specific methods to address them in a generalized utilitarian framework and 3 briefly illustrates the application of som e of these methods to the global distribution of incomes population sizes and longevity over the last century depending on the approach taken it is found inter alia that global social welfare in 2010 can be deemed to be between 1 8 and 407 times that of 1910 the role given to the quantity of lives bei ng particularly important in that assessment

the value of risk measuring the service output of u s commercial banks rather than charging direct fees banks often charge implicitly for their services via interest spreads as a result much of bank output has to be estimated indirectly in contrast to current statistical practice dynamic optimizing models of banks argue that compensation for bearing systematic risk is not part of bank output we apply these models and find that between 1997 and 2007 in the u s national accounts on average bank output is overestimated by 21 percent and gdp is overestimated by 0 3 percent moreover compared with current methods our new estimates imply more plausible estimates of the share of capital in income and the return on fixed capital

a generalized valuation model for fixed rate residential mortgages this paper uses option pricing techniques to rationally price mortgage instruments subject to both default and prepayment risk attention is given to terminations due to purely financial consideration of the mortgage contract itself as well as to personally induced terminations explicit inclusion of default in the mortgage valuation procedure also permits the valuation of insurance against such default qualitatively it is found that default differs significantly in the behavior from either prepayment or nonfinancial termination quantitatively however there is significant substitution between prepayment and default so that the addition of a default feature to the contract has only a modest impact on mortgage values unless there is substantial price volatility in the housing market or a high loan to value ratio copyright 1992 by ohio state university press

ranking income distributions a large variety of policy questions involve choices between social states and a consequent ordering of the feasible alternatives when these social states are related to the levels of welfare experienced by individuals or households two central issues stand out in determining the relative desirability of different social outcomes one of these is the essentially positive exercise of achieving comparability between households with different characteristics such as composition or preferences operating in different environments for example facing different price structures the other concerns the normative judgments implicit in the evaluation of alternative allocations of resourcesthe emphasis placed on inequality between households and the extent to which greater inequality can be compensated by higher average living standards this paper focuses on the second of these issues and in doing so we abstract from the problem of household comparability by considering a population of n households identical in all respects except for their incomes the question of ordering social states then becomes one of ranking income distributions over a group of anonymous households or individuals borrowing the usual assumptions imposed on consumer preferences we may suppose that a social ordering of income distributions can be represented by a welfare function 2

social criteria for evaluating population change abstract many applications of economic analysis require social evaluations of alternatives involving different numbers of people in this paper we use the tools of social choice theory to provide an axiomatic formulation of this problem it yields a class of social criteria called critical level generalized utilitarianism this class and its implications are compared with other criteria and are found to yield intuitively appealing results

a study on long run inefficiency levels of a panel dynamic cost frontier under the framework of forward looking rational expectations abstract this paper aims to provide a theoretical underpinning of the dynamic efficiency model pioneered by ahn s c good d h sickles r c 2000 estimation of long run inefficiency levels a dynamic frontier approach econometric reviews 19 461 492 in the context of a quadratic loss function this paper formulates a multi period forward looking rational expectations model on the evolution of the technical inefficiency level which correctly produces a dynamic panel data model the model is illustrated using panel data of 112 french banks encouraging evidence of superiority in favor of the model is reached substantial cost inefficiency prevails in this industry where the constituent banks are characterized as having volatile adjustment speeds toward their long run steady states the sample banks exhibit increasing returns to scale and product mix economies

the banking industry under uncertain monetary policy abstract the optimal loan decisions of banks are shown to be dependent on the banks rational forecast of the future federal funds rate which in turn is related to the policy rule used by the fed consequently a change in the policy of the fed will alter the reduced form model of the banking industry this result brings into question the fed s ability to predict and control the money stock under the procedure adopted by the fed between october 1979 and september 1982

banks as multioutput oligopolies an empirical evaluation of the retail and corporate banking markets the distinction between retail and corporate banking markets is of much importance in real life banking organizations the two markets differ with respect to concentration the importance of informational asymmetries and the extent of customer mobility within a standard conjectural variation model estimated on cost efficient banks as well as on the full sample of banks the authors empirically characterize the strategic behavior in each of these markets and also focus on cross market interactions to see whether initial moves in one market affect the equilibrium in the other market they compare their findings to the predictions that would follow from merely considering concentration ratios such as the herfindahl index

real output of bank services what counts is what banks do not what they own the measurement of bank output a difficult and contentious issue has become even more important in the aftermath of the devastating financial crisis of recent years in this paper we argue that models of banks as processors of information and transactions imply a quantity measure of bank service output based on transaction counts instead of balances of loans and deposits compiling new and comparable output measures for the united states and a range of european countries we show that our counts based output series exhibit significantly different growth patterns from those of our balances based output series over the years 1997 to 2009 since the u s official statistics rely on counts while european statistics rely on balances this implies a potentially considerable bias in the estimate of bank output growth in europe vis avis that in the united states

economies of superscale in commercial banking most previous studies of scale economies in banking have excluded banks larger than 1 billion in assets thus study by contrast estimates cost functions for the 100 largest us commercial banks hedonic terms are incorporated to correct for the aggregated nature of the call report data available for these banks in addition we attempt to quantify the cost benefit of diversification in the model we estimate efficient bank scale to range from 15 billion to 37 billion in total assets a thousandfold increase over some previous findings these results are supported by comparison of actual average costs as well as by casual historical observation and the level of widespread concern over interstate banking our findings suggest some cost incentive or benefit to expansion or consolidation among large regional banks including interstate expansion or consolidation

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

dynamic monetary control and interest rate stabilization abstract interest rate stabilization results in an instrument shortage that complicates monetary control by introducing strategic considerations into the trading desk s decision problem the paper demonstrates that when expected future open market operations influence current bank and depositor behavior an instrument shortage is necessary and sufficient for the commitment policy to be time inconsistent and for the discretionary policy to be suboptimal i e worse than the commitment policy the moving average component of the commitment policy is of higher order than the discretionary policy under either regime the expected value of the representative bank is increasing in the trading desk s emphasis on interest rate stability

imperfect competition in bank retail markets deposit and loan rate dynamics and incomplete pass through this paper examines determinants of pass through from the market interest rate to bank retail deposit and loan rates a dynamic adjustment cost model with imperfect competition implies that these rates depend on own lagged values and on lagged current and expected future values of the security rate greater competition in retail markets reduces the impact of lagged and expected rates on current retail rates while raising the effect of the current security rate yielding greater pass through these results have important implications for both the specifications used in empirical work and biases introduced into estimates of pass through effects

comment on what drives bank competition some international evidence the question of bank competition is vitally important for a number of reasons the essential role of bank credit and other financial services as an input in the production of most other goods and services places banks in a unique and influential position such that any allocative inefficiency or other market distortions in banking are almost certain to be felt throughout the economy moreover recent history has provided numerous instances where the textbook paradigm of atomistic competition has proven inadequate as a policy guide for efficient banking either because there are simply too few banks to rely on sheer numbers as a guarantee of vigorous competition as in canada or because of evidence that there can be such a thing as too much competition in banking as suggested by several studies or because of instances where nearly competitive pricing has been observed in markets containing only one or two banks or because conversely substantially noncompetitive pricing has sometimes been deduced in banking products such as credit cardswith thousands of suppliers thus the study of bank competition remains an urgent field of research claessens and laeven 2004 this issue of jmcb make two key contributions here first they extend a proven empirical method to an unprecedentedly large and varied crosscountry sample second they offer the logical and policy relevant additional step of seeking to identify factors associated with variations in measured conduct this step is needed to assess the empirical validity of the traditional structure conductperformance paradigm in their sample and is especially important where that paradigm is found lacking as a predictor of bank conduct indeed although the authors

does organizational form impact pricing asymmetry evidence from nonprofit financial institutions why output prices tend to rise faster in response to input cost increases than they fall in response to input cost decreases is a hotly debated issue in modern economics in this article i contribute to this asymmetric pricing debate by expanding the domain of organizational forms where this question has been investigated more specifically previous research has focused on for profit firms i expand the investigation by focusing on nonprofit organizations credit unions are the nonprofit organization used in my analysis credit unions provide essentially identical types of consumer financial services and products as commercial banks but do so from a very different not for profit orientation however in this study i document similar asymmetric rate setting behavior by credit unions this suggests that pricing asymmetry is likely to be much more widespread as it relates to nonprofit institutions as well as those in the for profit sector

bank size collateral and net purchase behavior in the federal funds market empirical evidence differences between large and small banks net purchase behavior in the uncollaterized federal funds and collateralized repurchase agreements markets are documented the larger a bank s asset size the larger ceteris paribus its federal funds purchases the threshold asset size is in the region of 1 billion to 2 5 billion for any size class banks located in major banking centers are more likely to be net federal funds purchasers than are banks located outside money centers in the collateralized repurchases agreements market there appears to be no size of locational discrimination indeed the smallest banks are the largest net purchasers as a fraction of assets of funds on the repurchases agreements market copyright 1989 by the university of chicago

short run cost inefficiency of commercial banks a flexible stochastic frontier approach we adopt the intermediation approach and use a flexible stochastic frontier to examine the cost efficiency of united states commercial banks with total assets in excess of million we find an average overall inefficiency of just under 10 percent a level somewhat lower than found in previous work our analysis of intra industry variation concludes that inefficiency generally rises with bank size further banks that have branching networks either domestic or foreign have higher inefficiency on average but at the same time inefficiency falls as the number of offices in the branch network expands state level data on the ease of serviceing the market competition from savings institutions and the financial sophistication of depositors significantly affect bank inefficiency generally with the expected signs finally our findings suggest that regulatory changes that increase capital requirements may lead to increased bank efficiency in the short run copyright 1994 by ohio state university press

a computational approach to the optimal structure of bank input prices abstract most bank deposits contain an embedded option which permits the depositor to withdraw funds at will demand deposits generally allow costless withdrawal while time deposits often require payment of an early withdrawal penalty managing the risk that depositors will exercise their withdrawal option is an important aspect of input pricing this paper acknowledges the threat of deposit withdrawal and then solves for the optimal structure of bank deposit rates

inequality among world citizens 1820 1992 this paper investigates the distribution of well being among world citizens during the last two centuries the estimates show that inequality of world distribution of income worsened from the beginning of the 19th century to world war ii and after that seems to have stabilized or to have grown more slowly in the early 19th century most inequality was due to differences within countries later it was due to differences between countries inequality in longevity also increased during the 19th century but then was reversed in the second half of the 20th century perhaps mitigating the failure of income inequality to improve in the last decades jel d31 f0 n0 o0

financial innovation the bright and the dark sides based on data from 32 countries over the period 1996 2010 this paper is the first to assess the relationship between financial innovation on the one hand and bank growth and fragility as well as economic growth on the other hand we find that different measures of financial innovation capturing both a broad concept and specific innovations are associated with faster bank growth but also higher bank fragility and worse bank performance during the recent crisis these effects are stronger in countries with larger securities markets and more restrictive regulatory frameworks in spite of these seemingly ambiguous findings our evidence points to a positive net effect of financial innovation on economic growth financial innovation is associated with higher growth in countries and industries with better growth opportunities

central bank secrecy interest rates and monetary control we construct a dynamic rational expectations model of the federal funds and deposit market that provides a rationale for central bank secrecy about current monetary aggregate objectives in this analysis the trading desk values secrecy because it reduces the influence of monetary control policy on interest rates we then examine actual u s experience with monetary control and determine that the reserve bias predicted by the model is present in the data from 1978 to 1985 finally we demonstrate that central bank secrecy may not lower the value of commercial banks

financial flexibility and the cost of external finance for u s bank holding companies this paper models a bank with access to two segmented capital markets the market for insured deposits and the market for uninsured claims we illustrate how higher costs of accessing either market leads to lower firm values and a greater incentive to carry liquid assets we test our model on a sample of large banking firms and label banks with relatively lower costs of accessing the two markets as more financially flexible our two key findings are 1 banks with greater financial flexibility have greater value and 2 banks with greater financial flexibility devote a smaller percentage of assets to cash and marketable securities consistent with the notion that financial flexibility reduces the sensitivity of firm profits to internal wealth shocks thus reducing the firm s need to carry financial slack

poverty human development and growth an emerging consensus this paper considers several issues relevant to the debate on the extent to which poverty or development progress in general should be measured by income or by a broader set of objectives issues covered here are practical implications of the two approaches for poverty reduction efforts the impact of growth on basic social indicators and how national achievement on social indicators is best measured sri lanka and pakistan countries often cited in this debate are used as examples

financial consumption and the cost of finance measuring financial efficiency in europe 1950 2007 this paper proposes to assess financial intermediation efficiency in germany france the uk and europe more broadly over the past 60 years i rely on philippon s 2012 methodology which calculates the unit cost of financial intermediation through the ratio of financial consumption measured by financial income to financial output approximated by the sum of outstanding assets intermediated the contribution of this paper is threefold first because financial industry va ignores banks capital income capital gains dividends and interest on securities it is an imperfect measure of the consumption of financial intermediation so long as capital income generates wages and profits to financial intermediaries it is akin to an implicit consumption of financial services using banking income instead of banking va to measure the consumption of banking services i show that the gdp share of finance has increased continuously in germany france the uk and europe as a whole second the unit cost of financial intermediation increased over the past 40 years except in france where overall it stagnated in addition the european unit cost matches the us unit cost calculated by philippon 2012 finally because financial intermediaries deal with nominal stocks and ows and because the unit cost increases during periods of monetary troubles i focus here on nominal rates of interest to explain the evolution of unit cost i show that a rise in nominal rates of interest increases the spread of bank interest so that 1970s and 1980s high unit costs are statistically explained by increases in short term interest rates on the other hand post 1990s high unit cost seems to coincide with the development of new market based activities

on the number and size of nations this paper studies the equilibrium determination of the number of countries in different political regimes and in different economic environments with more or less economic integration we focus on the trade off between the benefits of large jurisdictions and the costs of heterogeneity of large and diverse populations our model implies that i democratization leads to secessions ii in equilibrium one generally observes an inefficiently large number of countries iii the equilibrium number of countries is increasing in the amount of economic integration

social criteria for evaluating population change an alternative to the blackorby donaldson criterion abstract an ethical objection is raised against the blackorby donaldson criterion of optimum population maximizing the sum total of utilities in excess of some critical level since it may disprefer a social state with more people and with more worthwhile lives however the criterion may serve as a practicably reasonable compromise between maximizing total and average utility nevertheless an alternative compromise the maximization of number dampened total utility is proposed that is free from the above objection

retail bank deposit pricing an intertemporal asset pricing approach fundamentally spreads between market and deposit interest rates increase when interest rates rise and decline when rates fall recent empirical studies have found this phenomenon to be related to market concentration static equilibrium models are poorly equipped to explain this behavior in this paper the author applies an intertemporal asset pricing model incorporating bank deposits as a form of money in order to analyze the pricing behavior of a banking sector exercising market power his results extend the theoretical literature on deposit pricing and provide some insights into the behavior of interest rate spreads through time copyright 1995 by ohio state university press

liability management of financial intermediaries in a dynamic and uncertain perspective this paper examines the effect of rate uncertainty first for the loan rate alone next for both asset and liability rates on the liability funding decisions of a risk neutral intermediary in this model a la pindyck rates evolve according to stochastic processes convex adjustment costs arise from the dichotomy of existing core deposits and new savings balances and the intermediary s cash flow is embedded into capital market theory then we show that the stationary equilibrium obtains at the intersection of the locus of no change in deposit holdings with the isocline of zero change in savings balances loan rate uncertainty alone shifts the savings isocline outward when marginal adjustment costs are rising at an increasing rate but when asset and liability rates are uncertain their impact on the mean intermediation spread core deposit holdings and adjustment costs depends on whether they are correlated or not

beyond arbitrage good deal asset price bounds in incomplete markets one often wants to value a risky payoff by reference to prices of other assets rather than by exploiting full fledged economic models however this approach breaks down if one cannot find a perfect replicating portfolio we impose weak economic restriction to derive usefully tight bounds on asset prices in this situation the bounds assume that investors would want to buy assets with high sharpe ratios good deals as well as pure arbitrage opportunities we show how to calculate the price bounds in one period multiperiod and continuous time contexts we show that the multiperiod problem can be solved recursively as a sequence of one period problems we calculate bounds in option pricing examples including infrequent trading and an option written on a nontraded event and we use the bounds to explore the economic significance of option pricing predictions we find that much variation in s p 500 index option prices over time and across strike prices fits within the bounds

opec s kinked demand curve abstract asymmetric effects of oil prices on the macroeconomy imply multiple equilibrium prices for opec i estimate world demand for crude oil non opec supply and the effects of changes in price on world gdp using quarterly data covering 1973 to 2010 if opec s marginal cost is 20 bbl in 2014 iii and its discount rate is zero estimated equilibrium prices are 44 88 bbl multiple equilibria incent opec to tolerate unstable prices which because of the asymmetry lower world gdp both policies that increase responsiveness to price and policies that lower net demand to opec narrow and lower the range of equilibrium prices but the former are more effective at doing so opec responds to changes in the discount rate in the opposite way from competitive producers so policies that secure oil related property rights in opec countries and other policies that lower opec s discount rate narrow and lower the range of equilibrium prices monetary policy is more effective at accelerating or slowing macroeconomic activity the larger is opec s market share

the price concentration relationship in banking the commonly observed positive correlation between market concentration and profitability may be explained by noncompetitive pricing behavior as argued by the structure performance hypothesis or by the greater efficiency of firms with dominant market shares as argued by the efficient structure hypothesis by examining the price concentration relationship instead of the profit concentration relationship this paper tests the structure performance hypothesis in a manner that excludes the efficient structure hypothesis as an alternative explanation of the results the results strongly support the structure performance hypothesis and are robust with respect to model specification measurement of concentration and econometric technique copyright 1989 by mit press
