bank incentives economic specialization and financial crises in emerging economies abstract we model the vulnerability of an economy to a financial crisis as arising from the interaction of the degree of economic specialization and bank debt financing the probability of a financial crisis is shown to increase in the degree of economic specialization bank debt financing has the beneficial effect of lowering the degree of economic specialization by increasing access to financing of investment opportunities that would not have been financed due to wealth constraints of entrepreneurs financial access effect however bank debt financing induces risk shifting incentives leverage effect the net effect on the probability of a financial crisis depends on which of these two effects dominates we show that commonly employed mechanisms in managing financial crises particularly bailouts induce an additional agency cost by distorting bank incentives to concentrate loans in specific sectors bank debt concentration effect we propose a tax based ex ante solution mechanism that simultaneously induces optimal investment and eliminates the bank debt concentration effect implementation issues and empirical policy implications are also discussed

nonrenewable resource scarcity nonrenewable resource theory often is summarized by hotelling s rule this paper reviews theoretical extensions and empirical investigations of resource extraction models observed data are often inconsistent with the hotelling rule suggesting that other characteristics of nonrenewable resource supply including exploration heterogeneous ore quality technological progress and capital investment are important determinants of the dynamic behavior of resource prices given the persistent recurrence of concern about nonrenewable resource scarcity measures of nonrenewable resource scarcity and the empirical evidence for the time trends of those measures are reviewed finally the implications of nonrenewable resource scarcity for economic growth are examined

the effects of cross border bank mergers on bank risk and value abstract this paper examines the effects of cross border bank mergers on the risk and abnormal returns of acquiring banks we find that overall the acquirers risk neither increases nor decreases in particular on average neither their total risk nor their systematic risk falls relative to banks in their home banking market the abnormal returns to acquirers are negative and significant but are somewhat higher when risk increases relative to banks in the acquirer s home country

nonmonetary effects of the financial crisis in propagation of the great depression this paper examines the effects of the financial crisis of the 1930s onthe path of aggregate output during that period our approach is complementary to that of friedman and schwartz who emphasized the monetary impact of the bank failures we focus on non monetary primarily credit related aspects of the financial sector output link and consider the problems of debtors as well as those of the banking system we argue that the financial disruptions of 1930 33 reduced the efficiency of the credit allocation process and that the resulting higher cost and reduced availability of credit acted to depress aggregate demand evidence suggests that effects of this type can help explain the unusual length and depth of the great depression this abstract was borrowed from another version of this item

relative deprivation and internal migration in the united states a comparison of black and white men while the link between geographic and social mobility has long been a cornerstone of sociological approaches to migration recent research has cast doubt on the economic returns to internal u s migration moreover important racial disparities in migration patterns remain poorly understood drawing on data from the 2000 census the author reappraises the link between migration and social mobility by taking relative deprivation into consideration she examines the association between migration disaggregated by region of origin and destination and absolute and relative earnings and occupational prestige separately by race findings lend new insight into the theoretical and stratification implications of growing racial disparities in migration patterns while both blacks and whites who move north south generally average lower absolute incomes than their stationary northern peers they enjoy significantly higher relative social positions moreover the relative gains to migration are substantially large

alternative forms of deposit insurance pricing and bank incentive issues abstract this paper derives formulas for a deposit insuring agency s liability and hence a fair value deposit insurance premium and the equilibrium value of bank equity considering a wide variety of factors affecting individual bank risk both fixed rate and variable rate risk sensitive insurance systems are analyzed consideration is made as to whether the deposit insuring agency makes direct payments to depositors or arranges mergers following bank closings the effect of these various policy choices on banks incentive for risk taking is also analyzed

pricing risk adjusted deposit insurance an option based model this paper presents a methodology for arriving at empirical estimates of deposit insurance premiums from market data by using isomorphic relationships betweeen equity and a call option and insurance and a put option the data utilizes the market value of equity to solve for the asset value and its volatility market perceptions of fdic bailout policies are explicitly modeled so as to eliminate the bias in inverted values of assets and their volatility sensitivity analyses are performed to show that rank orderings based on premiums are robust to changes in specification thus facilitating allocation of aggregate premium across banks while economists have long argued in favor of risk adjusted deposit insurance as both more equitable and more efficient than the current system of flatrate premiums various recent developments have further contributed to an increasing dissatisfaction with the current system first both the banking industry and the government seem to be tending to the view that deregulation of the banking industry would be necessary in order to meet more sophisticated future demands on the industry as well as desirable as a policy means of stimulating greater competition among banks moreover a sudden rise in the incidence of bank failures 1 and the vulnerability of the u s banks to the socalled international debt crisis have served to bring to the fore concern about the health of the banking industry in the absence of deposit insurance riskier banks will be able to attract deposits only at higher rates and these higher costs of funding serve as built in market regulated incentives to limit excessive risk taking by banks as introduction of deposit insurance makes deposits equally risk free across banks these incentives disappear and regulation and close supervision of the banking industry must necessarily replace them as deterrents to excessive risk taking thus when insurance is offered at a flat premium regulation is designed to ensure that the risk posed to the insurer both asset and financial risk is appropriately uniform

rural urban migration household vulnerability and welfare in vietnam summary this paper investigates the interaction of migration vulnerability to poverty and welfare of rural households in three provinces in central vietnam it addresses three questions 1 to what extent do shocks motivate rural household members to move to urban areas 2 are migrants in the new urban settings better off in terms of working conditions and quality of life and 3 what is the effect of migration on rural household s welfare and vulnerability to poverty the analysis uses panel data of 2200 households from rural vietnam covering the period 2007 2010 and a tracking survey of 299 migrants from 2010 the empirical evidence from a probit model shows that migration especially migration for employment is a livelihood support strategy for households exposed to agricultural and economic shocks migration for education is more likely observed among households with higher human capital and being financially better off nevertheless the probability of migration decreases with the employment opportunity in the village migrants perceive themselves to be better off at the place of destination but income losses from shocks of their rural households may reduce their employment quality the results from difference in difference specifications with propensity score matching techniques suggest that migration has positive income growth effects and that these effects are more pronounced in provinces with fewer job opportunities these effects help not only migrant households moving out of poverty but it also improves the poverty situation in rural areas

deposit insurance reform what are the issues and what needs to be fixed abstract the current problems in the commercial banking industry have led to widespread calls for reform of the deposit insurance contract on the grounds that it promotes moral hazard we review the empirical evidence for the significance of moral hazard as an important cause of the present crisis we then evaluate various reform proposals grouped into two broad classes proposals that seek to impose greater discipline on bank stockholders and proposals to increase the disciplinary role of bank debtholders finally we identify some issues that have received inadequate attention in the literature on bank regulation

does relative deprivation induce migration evidence from sub saharan africa this analysis revisits the decades old relative deprivation theory of migration in contrast to the traditional view that migration is driven by absolute income maximization we test whether relative deprivation induces migration in the context of sub saharan africa taking advantage of the internationally comparable longitudinal data from integrated household and agriculture surveys from tanzania ethiopia malawi nigeria and uganda we use panel fixed effects to estimate the effects of relative deprivation on migration decisions using per capita consumption expenditure and multidimensional wealth index as well being measures we find that a household s migration decision is based not only on its absolute well being level but also on the relative position of the household in the well being distribution of the community in which it resides we also discover that the effect of relative deprivation on migration is amplified in rural agricultural and male headed households results are robust to alternative specifications including the use of hausman taylor instrumental variable htiv estimator and pooled data across the five countries results confirm that the migration relative deprivation relationship also holds in the context of sub saharan africa we argue that policies designed to check rural urban migration through rural transformation and poverty reduction programs should use caution because such programs can increase economic inequality which further increases migration flow

the impact of contingent liability on commercial bank risk taking abstract from 1863 1935 regulators imposed contingent liability on bank shareholders to discourage risk taking using data from 1900 to 1915 i find that banks subject to stricter liability rules have lower equity and asset volatility hold a lower proportion of risky assets and are less likely to increase their investment in risky assets when their net worth declines consistent with the hypothesis that stricter liability discourages commercial bank risk taking these findings provide lessons for current bank regulatory policy and show that the shape of the residual claimant s payoff function has a significant impact on managerial incentives and firm performance

risk shifting incentives of depository institutions a new perspective on federal deposit insurance reform abstract we characterize the risk shifting incentives of a depository institution as arising fundamentally from the existence of limited liability and the associated convex payoff to equity holders this risk incentive feature is unchanged by deposits being insured and hence excessive risk taking by depository institutions is not solely attributable to the flat rate insurance premium consequently the incentive problem cannot be resolved through a risk based insurance premium contrary to the prevailing view we propose a solution that eliminates risk shifting through an optimal tax structure and specify a corresponding insurance premium that is revenue neutral from the social planner s regulator s standpoint the solution is derived in the context of a social objective function that trades off the benefits of liquidity services by banks and the unique informational role of bank loans with the costs of investment distortions engendered by risk shifting

appearance and reality in deposit insurance the case for reform abstract this paper argues that the staffs and explicit insurance reserves of u s deposit insurers have been overwhelmed by de facto financial disaster the full costs of financing federal deposit insurance have become enormous and increasingly inequitable in distribution to reduce voluntary risk taking authorities must reprice and redesign the system of de facto deposit insurance coverage six complementary reforms are discussed 1 accounting for institutional assets liabilities and net worth at market value 2 enhancing opportunities for deposit insurers to manage their risk exposure 3 recalibrating insurance coverages 4 imposing risk rated premiums 5 mixed private and governmental competition in deposit insurance and 6 constraining insurance agency and federal reserve authority to bail out insolvent institutions

the structure and incentive effects of corporate tax liabilities this paper describes situations in which tax liabilities assume the form of a negative position in a call option this structure motivates an examination of the investment decisions of taxed corporations in the presence of risk it is shown that the structure of the tax liability creates an incentive to underinvest in more risky projects and an incentive for conglomerate merger these effects are then evaluated in the presence of conflicts of interest between stockholders and bondholders and under alternative assumptions about the tax code and about the timing of investment and financing decisions this paper makes an observation regarding the functional form assumed by the tax liabilities of corporations with potentially redundant deductions and evaluates its consequences for investment incentives interest and other deductions against taxable income can be taken for the most part only to the extent of that income in a single period model this gives the net tax liability a familiar structure it can be viewed as a call option where the exercise price on the call is the allowable deductions the tax paying entity holds a positive position in the assets which generate the taxable income and a negative position in a call option on those assets the analogy between options and the structure of tax liabilities calls attention to some interesting incentive effects concerning risk using their model of option valuation black and scholes 5 showed that the value of an option is increasing in the variance of the asset it is written on other authors have generalized this result and studied its implications for corporate financing see jagannathan 16 jensen and meckling 17 and green 15 the importance of the risk attributes of the underlying asset in option valuation suggests that taxation may have important incentive consequences for investment decisions involving risk it has been recognized in the public economics literature for some time that asymmetries in the tax schedule can affect risk taking behavior early papers by mossin 20 and stiglitz 25 studied individual portfolio decisions over a riskless and a risky asset our analysis differs from these in a number of respects the most important of these is our use of market valuation rather than expected utility in the decision maker s objective function this is surely a more appropri

geometric brownian motion and structural breaks in oil prices a quantitative analysis the purpose of this paper is to present a quantitative analyses of oil price s path we try to argue that despite its parsimony and simplicity geometric brownian motion can perform well as a proxy for the movement of oil prices and for a state variable to evaluate oil deposits we base our argument on evidences of very low speed of mean reverting or long half life since unit root tests only can reject its null hypothesis in a sample longer than 100 years on the other hand we reject the null hypothesis of unit root with two endogenous breaks showing that the usual rejection can be attributed to omitted structural breaks we conclude that the average half life of oil price between 4 and 8 years depending on the model chosen is long enough to allow a good approximation as a geometric brownian motion

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

the s l debacle public policy lessons for bank and thrift regulation this book describes the period of failures of savings and loan associations and sets out a program of policies to prevent future debacles it explains the regulatory actions and inactions that created the incentives for large numbers of thrifts to make excessively risky and ill conceived and in some cases fraudulent and criminal investments it describes the failure of the accounting system to provide adequate information to regulators and in many cases even to the managers of the thrifts themselves concerning the health and riskiness of individual thrifts it also discusses how the regulatory system that had been conceived in an earlier and highly regulated era was overwhelmed in the deregulated environment of the early 1980s it shows how the reforms that were made in response to the growing crisis were too little and too late and finally it offers a set of policy reforms that could prevent future crises in the savings and loan industry this work should be of interest to political and financial economists

forbearance deposit insurance pricing and incentive compatible bank regulation abstract this paper examines the incentive compatible role of regulatory forbearance policy in the context of optimal bank regulation under moral hazard we show that when a bank s asset portfolio returns have market risk the regulator can influence the bank s choice of ex ante risk by delaying the closure of an insolvent bank the optimal closure policy involves co ordinating the closure decision with market wide performance such a policy may significantly alleviate the bank s ex ante risk shifting problem furthermore even fixed rate deposit insurance can be optimal when combined with a sound forbearance policy and a minimum capital standard

estimating the effects of information surprises and trading on stock returns using a mixed jump diffusion model i present a methodology that uses the mixed jump diffusion model for stock returns to estimate the separate effects of information surprises and strategic trading around corporate events using simulation techniques i show that for events with multiple announcements spread over a long time the estimators derived from the mixed jump diffusion model are more powerful compared to the traditional cumulative abnormal return estimators the new methodology is used to study the separate effects of information surprises and strategic trading associated with blockholdings and subsequent targeted repurchases i find that for more than 93 percent of the firms in our sample the mixed jump diffusion model is statistically superior to the pure diffusion model in describing stock returns more important i find a statistically significant negative effect due to trading while the average effect around announcements is statistically insignificant in contrast the standard cumulative abnormal return is not statistically different from zero article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

capital regulation and deposit insurance abstract a model of deposit insurance in which the bank closure rule can systematically deviate from the economic insolvency condition used in earlier models is developed simulation of that model for plausible parameter values suggests that the failure to close banks on a timely basis has a profound effect in increasing the insurer s liability the implications of these results for capital regulation are discussed

state contingent regulatory mechanisms and fairly priced deposit insurance abstract this paper presents a model of incentive compatible bank regulation under moral hazard and adverse selection we derive a wide range of simple and conceptually implementable mechanisms that can solve each type of incentive problem separately and also achieve the first best outcome but only when regulatory instruments involve ex post pricing that is contingent on the bank s performance relative to the market an important feature of these mechanisms is that they do not involve a subsidy to the bank when the regulator faces both moral hazard and adverse selection simultaneously we identify the conditions under which the same mechanism can achieve the first best solution

variable rate deposit insurance a re examination abstract this paper investigates the impact of variable rate deposit insurance on the financial and real sectors of the economy and its role as an absorber of bankruptcy risk within these sectors a variable rate system raises the cost of funds to the real sector and increases probability of bankruptcy of the borrowing firms when such bankruptcies occur society experiences a dead weight loss we argue that appropriate deposit insurance pricing must weigh the social costs connected with both financial firm failure and real sector bankruptcy

do different types of assets have differential effects on child education evidence from tanzania to assess the conventional view that assets uniformly improve childhood development through wealth effects this paper tests whether different types of assets have different effects on child education the analysis indicates that household durables and housing quality have the expected positive effects but agricultural assets have adverse effects on highest grade completed and no effects on exam performance extending the standard agricultural household model by explicitly including child labor the study uses three waves of panel data from tanzania to estimate the effects of household assets on child education the analysis corrects for the endogeneity of assets and uses a hausman taylor instrumental variable panel data estimator to identify the effects of time invariant observables and more efficiently control for time invariant unobservables the negative effect of agricultural assets is more pronounced among rural children and children from farming households presumably due to the higher opportunity cost of their schooling

network effects and the dynamics of migration and inequality theory and evidence from mexico international migration is costly and initially only the middle class of the wealth distribution may have both the means and incentives to migrate which can increase inequality in the sending community however the migration networks formed lower the costs for future migrants which can in turn lower inequality this paper shows both theoretically and empirically that wealth has a nonlinear effect on migration and then examines the empirical evidence for an inverse u shaped relationship between emigration and inequality in rural sending communities in mexico after instrumenting we find that the overall impact of migration is to reduce inequality across communities with relatively high levels of past migration we also find some suggestive evidence for an inverse u shaped relationship among communities with a wider range of migration experiences

federal deposit insurance regulatory policy and optimal bank capital this paper seeks to explain the combination of explicit and implicit pricing for deposit insurance employed by the fdic essentially the fdic sells two products insurance and regulation to span the product space it must and does set two prices we argue that the need to establish regulatory disincentives to bank risk taking is the heart of the controversy over the adequacy of bank capital and that the ability to close risky banks before exhausting their charter value i e the value of their right to continue in business stands at the center of these disincentives and in front of the fdic s insurance reserves just as a book shouldn t be judged by its cover a government agency shouldn t be judged by the words behind its initials with the fdic federal deposit insurance corporation the agency s name describes only part of its formal operations the fdic is quasi governmental has a regional structure and sells deposit insurance however the initials fail to convey the fdic s critical place in the governmental regulatory structure as the sole federal overseer of the approximately 8900 state chartered commercial banks that have chosen not to belong the federal reserve system reflecting the federal reserve s membership problem the number of these banks is growing year by year besides selling deposit insurance at bargain explicit rates the fdic performs four regulatory functions 1 entry regulation it passes on new banks applications for deposit insurance and on branch and merger proposals as well thereby protecting the value of existing bank charters 2 examination two thirds of fdic employees are concerned with inspecting bank records and supervising managerial activity 3 regulation of deposit rates and conditions for withdrawal by tradition fdic policies on these matters conform entirely with regulations applicable to federal reserve member banks and 4 disposition of failed banks when an insured bank fails the fdic usually chooses not to liquidate it 2

jump dynamics with structural breaks for crude oil prices this study investigates the joint phenomena of permanent and transitory components in conditional variance and jump intensity along with verification of structural breaks for crude oil prices we adopt a component arji model with structural break analysis utilizing daily data on west texas intermediate crude oil spot and futures contracts the analytical results verify the existence of permanent and transitory components in conditional variance with the permanent component of conditional variance increasing with the occurrence of a sudden major event such as the iraqi invasion of kuwait operation desert storm and the war between the us and iraq and a relatively greater increase in the transitory component over the same period notably jump intensity fluctuates with an increase in the transitory component of conditional variance in response to abnormal events it is the transitory component which serves as the primary influential factor for jumps in returns therefore speculators are willing to take large risks particularly with respect to anticipating future price movements or gambling in the hopes of rapidly making substantial gains thus speculators prefer the temporary volatility component and engage in trade activities however investors prefer the permanent volatility component because they may well be better off relocating their assets into more stable portfolios to outperform the market portfolio over the long run

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

risk management in the global economy a review essay abstract this paper provides a review of developments in the area of risk management at both the firm level and the macro economy we review rationales regarding why firms choose to manage risk as well as new developments in measuring and managing risk in a dynamic setting we also consider current risk sharing arrangements in light of the theory regarding optimal risk sharing the paper concludes with some suggestions for additional research that emphasizes the importance of incorporating market incompleteness in an equilibrium setting we also discuss the role of incompleteness at the macro level and speculate on how derivatives markets may influence macro economic stabilization policy

the valuation of fdic deposit insurance using option pricing estimates when congress set the premium rate for fdic deposit insurance in the banking act of 1935 which authorized a permanent federal insurance system neither experience nor theory could offer much guidance regarding an appropriate fee structure although rates have since been periodically revised the fdic has yet to attempt to set the insurance rate at a ifair level that is a level equal to administrative costs plus the ex ante value of the insurance such a premium is the rate that would be charged by competitive private insurers however7 the garn st germain act of 1982 directed the fdic to consider the feasibility of a risk based premium structure in response the fdic has suggested a trial system in which each insured bank will be placed in one of three risk classes based on credit and interest rate risk relative to capital and a premium rate will be assigned to each group those rates will be determined in part by the loss experience of the entire banking system fdic 1983 another approach to the determination of the appropriate insurance premium has been offered by merton 1977 who suggested using the analogous relationship between deposit guarantees and put options to value fdic insurance in this paper we follow merton s suggestion and calculate bank specific estimates of the proper premium for deposit insurance for the banks in our sample we find that fdic rates greatly exceed estimates of the fair value of the insurance derived from the blackscholes 1972 option pricing model

deposit insurance and financial development the authors examine the effect of different design features of deposit insurance on long run financial development defined to include the level of financial activity the stability of the banking sector and the quality of resource allocation their empirical analysis is guided by recent theories of banking regulation that employ an agency framework the authors examine the effect of deposit insurance on the size and volatility of the financial sector in a sample of fifty eight countries they find that generous deposit insurance leads to financial instability in lax regulatory environments but in sound regulatory environments deposit insurance does have the desired impact on financial development and growth thus countries introducing a deposit insurance scheme need to ensure that it is accompanied by a sound regulatory framework otherwise the scheme will likely lead to instability and deter financial development in weak regulatory environments policymakers should at least limit deposit insurance coverage

bank regulation and monetary policy the depository institutions deregulation and monetary control act 1980 and the garn st germain depository institutions act 1982 are the two most significant pieces of bank legislation since the 193os their significance stems from the fact that they have sought to roll back a number of the regulations and restrictions imposed on bank activity and competition in the 1933 80 period among the important provisions of these acts are a gradual elimination of regulation q ceilings on time and savings deposits by march 1986 the amelioration of state imposed usury ceilings on loans the nationwide provision of interest bearing transaction type accounts negotiable order of withdrawal now and super now accounts permission for thritts to expand into bank like products such as commercial and industrial loans consumer loans and credit cards and the development of new types of savings accounts such as mmdas l in addition to legislative deregulation we have also witnessed homemade deregulation as banks have sought to exploit often with great success loopholes in the bank holding

rural to urban migration in ldcs a relative deprivation approach ithe basic premises of this paper are a given a person s own current income his satisfaction or deprivation is some function of income statistics other than this income e g a statistic based on the incomes of some not necessarily all other persons and b that rural to urban migration is undertaken in order to improve a person s position in terms of the latter statistic as is often the case when an old approach relative deprivation is applied to a new area migration the ideas presented here are exploratory and illustrative and have not yet been subjected to complete and formal empirical verification nonetheless the usefulness of this approach in offering novel explanations to migration related phenomena opens a promising avenue of research in a field where empirical work abounds but theory is still fairly weak and all too often somewhat ad hoc premise a builds on the notion that people are engaged in interpersonal income comparisons which are internalized thus generating psychic costs or benefits frustrations or elations relative deprivation or satisfaction viewing migration as an act of choice premise b builds on the notion that these factors motivate locational decisions relative deprivation is an important factor affecting people s choices which has been overlooked by the received migration theory working through a large number of village studies 2 i have observed several interesting and largely unexplained regularities 1 rural to urban migration rates are not highest from the poorest villages 2 migration rates are higher from villages where the distribution of income by size is more unequal and 3 from these villages it is the very poor whose propensity to migrate is highest conventional migration theory linking migration propensities causally and positively to intersectoral income differentials fails to predict 1 nor does it offer

accounting for banks capital regulation and risk taking this paper examines risk taking incentives in banks under dierent accounting regimes with capital regulation in the model the bank s decisions of capital issuance and investment policy are jointly determined given exogenous minimum capital requirement the bank is more likely to issue equity capital in excess of the minimum required level and implement less risky investment policy under either lower of cost ormarket accounting or fair value accounting than under historical cost accounting but fair value accounting may induce more risk taking compared to lower of cost or market accounting due to short term interest in the part of the bank however the disciplining role of lower of cost or market accounting may discourage bank s incentive to exert project discovery eort

forecasting crude oil market volatility further evidence using garch class models abstract this paper extends the work of kang et al 2009 we use a greater number of linear and nonlinear generalized autoregressive conditional heteroskedasticity garch class models to capture the volatility features of two crude oil markets brent and west texas intermediate wti the one five and twenty day out of sample volatility forecasts of the garch class models are evaluated using the superior predictive ability test and with more loss functions unlike kang et al 2009 we find that no model can outperform all of the other models for either the brent or the wti market across different loss functions however in general the nonlinear garch class models which are capable of capturing long memory and or asymmetric volatility exhibit greater forecasting accuracy than the linear ones especially in volatility forecasting over longer time horizons such as five or twenty days

oil prices speculation and fundamentals interpreting causal relations among spot and futures prices abstract a consensus that the world oil market is unified begs the question where do innovations in oil prices enter the market here we investigate where changes in the price of crude oil originate and how they spread by examining causal relationships among prices for crude oils from north america europe africa and the middle east on both spot and futures markets results indicate that innovations first appear in spot prices for dubai fateh and spread to other spot and futures prices while other innovations first appear in the far month contract for west texas intermediate and spread to other exchanges and contracts links between spot and futures markets are relatively weak and this may have allowed the long run relationship between spot and future prices to change after september 2004 together these results suggest that market fundamentals initiated a long term increase in oil prices that was exacerbated by speculators who recognized an increase in the probability that oil prices would rise over time

financial system design and liquidity provision by banks and markets in a dynamic economy this paper contributes to the literature on financial system design by comparing markets and banks in a dynamic economy investors trade off their liquidity needs against the high returns on illiquid investments both the banking system and the market can provide partial liquidity insurance to investors we consider full market participation as well as limited market participation we demonstrate that the full participation market with intergenerational trading can provide more liquidity than one without insurance is provided through wealth transfer across generations instead of cross subsidization across contemporaneous types as is the case in the finite economy given a full participation market that allows trading across generations only banks with initial capital can provide additional liquidity in a limited participation market with uncertainty about trading types an intergenerational bank with or without initial capital provides additional insurance to investors the need for trade is eliminated finally if there is no uncertainty about trading types then an intergenerational bank with initial capital eliminates the need for trading and improves welfare for all an intergenerational bank without initial capital improves welfare for people who do not trade

is fairly priced deposit insurance possible we analyze risk sensitive incentive compatible deposit insurance in the presence of private information and moral hazard without deposit linked subsidies it is impossible to implement risk sensitive incentive compatible deposit insurance pricing in a competitive deregulated environment except when the deposit insurer is the least risk averse agent in the economy we establish this formally in the context of an insurance scheme in which privately informed depository institutions are offered deposit insurance premia contingent on reported capital the result holds for alternative sorting instruments as well this suggests a contradiction between deregulation and fairly priced risk sensitive deposit insurance this paper exposes a conflict between a deregulated competitive financial services industry on the one hand and fairly priced risk sensitive deposit insurance on the other we show that if depository institutions dis are perfectly competitive i e each makes zero profits on average then it is impossible to implement incentive compatible risk sensitive deposit insurance pricing recent distress among dis has fueled debate about reform of the existing deposit insurance system many believe that the prevailing risk insensitive premium structure encourages dis to choose excessively risky assets and that it should be replaced by deposit insurance premia linked to the dis choices of risk 2 risk sensitive deposit insurance pricing however imposes greater informational demands on the deposit insurer and runs afoul of both

relative deprivation and migration preferences in this letter we overcome the existing shortages with respect to the assignment of individuals to reference groups and are the first to show that individual aversion to relative deprivation plays a decisive role in shaping migration preferences

top management compensation and capital structure the interrelationship between top management compensation and the design and mix of external claims issued by a firm is studied the optimal managerial compensation structures depend on not only the agency relationship between shareholders and management but also the conflicts of interests which arise in the other contracting relationships for which the firm serves as a nexus we analyze in detail the optimal management compensation for the cases when the external claims are 1 equity and risky debt and 2 equity and convertible debt in addition to the role of aligning managerial incentives with shareholder interests managerial compensation in a levered firm also serves as a precommitment device to minimize the agency costs of debt the optimal management compensation derived has low pay performance sensitivity with convertible debt instead of straight debt the corresponding optimal managerial compensation has high pay to performance sensitivity a negative relationship between pay performance sensitivity and leverage is derived our results provide a reconciliation of the puzzling evidence of jensen and murphy 1990 with agency theory other testable implications include 1 a relationship between the risk premium in corporate bond yields and top management compensation structures and 2 the announcement effect of adoption of executive stock option plans on bond prices the model yields implications for management compensation in banks and federal deposit insurance reform our results explain the dynamics of top management compensation in firms going through financial distress and reorganization

a characterization of oil price behavior evidence from jump models abstract this paper is concerned with the statistical behavior of oil prices in two ways it firstly applies a combined jump garch model in order to characterize the behavior of daily weekly as well as monthly oil prices secondly it relates its empirical results to implications of hotelling type resource extraction models the empirical analysis shows that oil prices are characterized by garch as well as conditional jump behavior and that a considerable portion of the total variance is triggered by sudden extreme price movements this finding implies that first oil price signals are not reliable and as a consequence both finding optimal extraction paths and decisions regarding the transmission to alternative technologies are likely to be compromised second this behavior is in stark contrast to the notion of deterministic trends in the price of oil

oil price hikes and development triggers in peace and war the theory of irreversible investment predicts that development of an oil field should take place when a unique price trigger is passed at the start of the 1990 91 gulf war however oil prices promptly doubled only to fall back to their previous level when peace returned six months later to incorporate such large but transitory price hikes we evaluate the profitability of an oil field contingent on war and peace and calculate separate triggers in each case for plausible parameter values we find that the switch between these development triggers is about 45 of the price hike caused by the war the price hike is therefore equivalent to a permanent price increase of only a quarter of its size copyright 1996 by royal economic society

migration remittances and inequality estimating the net effects of migration on income distribution this paper examines the net effects of migration and remittances on income distribution potential home earnings of migrants are imputed as are the earnings of non migrants in migrant households in order to construct no migration counterfacmals to compare with the observed income distribution including remittances the earnings functions used to impute migrant home earnings are estimated from observations on non migrants in a selection corrected estimation framework which incorporates migration choice and labor force participation decisions for a sample of households in bluefields nicaragua migration and remittances increase income inequality when compared with the no migration counterfactual 1998 elsevier science b v

investment incentives debt and warrants abstract this paper models and characterizes investment incentive problems associated with debt financing the decision problem of residual claimants is explicity formulated and their investment policies are characterized the paper also analyzes the use of conversion features and warrants to control distortionary incentives these claims reverse the convex shape of levered equity over the upper range of the firm s earnings and this mitigates the incentive to take risk it is shown that under certain conditions such claims can be constructed to restore net present value maximizing incentives and simultaneously meet the financing requirements of the firm

corporate financial policy and the theory of financial intermediation this paper examines the optimal structure of financial contracts in an economy subject to two forms of moral hazard multiple information problems are shown to generate a role for multiple classes of financial claimants we then show that economic efficiency is enhanced if the financial structure of the economy consists of both direct and intermediated financial contract markets consequlently our results demonstrate a motivation for the complementarity between capital markets and depository financial institutions the purpose of this paper is to provide an analysis of the complementary roles of direct financial contract markets and intermediated financial contract markets in the modern theory of corporate finance the need to formulate such a model has been emphasized elsewhere by stiglitz 1985 and fama 1985 among others however an adequate explanation of this phenomenon has yet to be formulated the model described in this paper focuses on the role of multiple information problems in a theory of complex financial structure specifically in an environment with private action i e unobservable investment allocations and private information i e partially unobservable project cash flows multiple claimant classes arise to resolve the separate inefficiencies induced by moral hazard in our model the interaction of project risk and observability creates investment distortions which can be mitigated by increasing the number of outside claimant classes our results demonstrate explicitly the way in which a firm s optimal financial structure depends on the assumed configuration of an investment project s risk and observability characteristics under certain conditions we show that the optimal contractuai allocation in an economy with only direct financial contract markets consists of a debt contract and an outside equity claim this contractual configuration restores the efficient investment allocation decision we then consider the feasibility of an intermediated financial contract market in this setting we show that the existence of an intermediated financial contract market improves economic efficiency due to the reduced aggregate costs of

optimal capacity in the banking sector and economic growth the paper investigates from the welfare and growth point of view the determination of the optimal capacity of the banking system for that purpose we consider an overlapping generation model with endogenous growth there is horizontal differentiation and imperfect competition in the banking sector macroeconomic shocks affect the return on capital and together with the expectations of depositors condition the stability of the banking sector we specify to what extent deposit insurance may reduce instability and increase the number of deposits welfare and growth we also characterize the conditions under which excess banking capacities may appear and how their reduction may improve welfare

world crude oil and natural gas a demand and supply model abstract this paper examines world markets for crude oil and natural gas over the period 1918 1999 it analyzes the time series properties of output and prices and estimates demand and supply elasticities during 1918 1973 and 1973 1999 oil and gas prices were stable during the first period they became volatile afterwards reflecting deep changes in the market structure following the oil shock in 1973 demand price elasticities were too low however demand income elasticities were high supply price elasticities were also too low the elasticity estimates help to explain the market power of the oil producers and price volatility in response to shocks and corroborate elasticity estimates in energy studies

capital regulation and insured banks choice of individual loan default risks abstract how bankers choose the riskiness of their individual assets is an important question it is well known that fixed premium deposit insurance leads a bank to prefer a high variance asset portfolio but its effect on individual asset choice has not been carefully evaluated this paper demonstrates how bank examination procedures and capital adequacy standards can make the value of a bank s deposit insurance contract concave in individual asset risks insured bankers may therefore have a rational preference ceteris paribus for relatively safe individual loans even while they prefer risky portfolio returns the model s implications for loan securitization and the federal regulators new risk based capital standards are discussed

migration incentives migration types the role of relative deprivation the authors explore the role of relative deprivation versus absolute income as an incentive for migration in developing countries in section i of this paper we outline the relative deprivation model of migration and present an illustration of the divergent policy implications of a relative deprivation model versus an absolute income model an attempt is made to identify distinct empirical implications of relative and absolute income motives for migrating in section ii a migration decision model is estimated and is used to explore absolute and relative income motives for internal and international migration in a sample of rural mexican households as well as to test the extent to which discontinuity in labour markets shapes the choice of migrant destination in section iii we present our conclusions excerpt
