taxation government spending and labor supply a diagrammatic exposition the effects of a change in the level of taxation on labor supply are examined under the assumption that the government budget balances the government spends tax revenues either on redistributions which are assumed to have an income effect on labor supply or on other government goods which are assumed not to influence labor supply in order for a rise in the tax rate to increase the quantity of labor supplied it must be that i the labor supply function bends backward and ii sufficiently little of the increased tax revenues are redistributed the quantity of labor supplied must fall if all marginal tax revenues are redistributed

the social costs and benefits of too big to fail banks a bounding exercise while the policy of too big to fail has received wide attention in the literature there is little agreement regarding economies of scale for financial firms we take the stand that systemic risk increases when the larger players in the financial sector have a larger share of output calculations indicate that the cost to the macro economy due to increased systemic risk is always much larger than the potential benefit due to scale economies when distributional and intergenerational issues are considered the potential benefits to economies of scale are unlikely to ever exceed the potential costs due to increased risk of a banking crisis

banking business models and the nature of financial crisis in our paper we analyze the heterogeneity between various business models among systemically important banks in 65 countries over the period of 2000 2012 for the first time we are able to identify true banking strategies consisting of different combinations of bank asset and funding sources and assess their impact on the mortgage crisis we then estimate how distinct strategies have affected bank profitability and risk before the crisis and what impact they have put on the mortgage crisis our results prove that the asset structure of banks was responsible for the systemic risk before the mortgage crisis whereas the liability structure was responsible for the crisis itself finally we show that countries with banks that rely on investment activities experienced a greater but more short lived drop in gdp compared to countries that have a predominantly traditional banking sector

distortionary taxes and the provision of public goods economists have long been concerned with finding an efficient level of public expenditure the classic statement of the problem was given by paul samuelson 1954 an optimal level of expenditure is where the sum of the marginal rates of substitution between the public good and a reference good equals the marginal rate of transformation between the public good and the reference good mrs mrt however samuelson s formula assumes that all of the revenue needed to finance public goods can be raised with lump sum taxes since this is not generally possible the formula must be modified to account for the distortionary effects of the tax system an appropriate modification is to multiply the cost side of the equation by a term that is commonly called the marginal cost of public funds mcf in the case of samuelson s formula where government is entirely financed with lump sum taxes the mcf would be exactly 1 0 in the traditional view of economists distortionary taxes cause the mcf to be greater than one thus raising the cost of providing public goods in this paper we discuss some cases where the mcf may be less than one we will illustrate this possibility using numerical examples for labor taxes

financial intermediary coalitions abstract in this article an environment in which the investment opportunities of agents are private information is studied and it is shown that financial intermediaries arise endogenously within that environment it is established that financial intermediaries are part of an efficient arrangement in the sense that they are needed to support the authors private information core allocations these intermediaries which are coalitions of agents exhibit the following characteristics in equilibrium they borrow from and lend to large groups of agents they produce information about investment projects and they issue claims that have different state contingent payoffs than claims issued by ultimate borrowers

hedging and coordinated risk management evidence from thrift conversions we provide an explanation for hedging as a means of allocating rather than reducing risk we argue that when increases in total risk are costly firms optimally allocate risk by reducing increasing exposure to risks that provide zero positive economic rents our evidence shows that mutual thrifts that convert to stock institutions increase total risk following conversion consistent with their increased abilities and incentives for risk taking they achieve this increase by hedging interest rate risk and increasing credit risk we provide some evidence that risk management activities are related to growth capacity and management compensation structure attained at conversion

regulating banks through market discipline a survey of the issues abstract the interest in the application of market discipline to regulate the financial industry has boomed recently due to the proposed new capital accord this paper reviews the potential role market discipline can play in financial regulation we start with a discussion of the rationale for financial regulation and with a brief history of the current regulatory mechanisms next a definition of market discipline as a regulatory mechanism is advanced we evaluate the disciplining power various market participants have finally we argue that more external risk management disclosure is a condition sine qua non in order to enable market discipline as a regulatory mechanism in this respect the basle committee has taken the right approach

the nature of government expenditures and the shape of the laffer curve abstract the existence of a negatively sloped section on the tax revenue tax rate relationship is shown to crucially depend on the nature of government expenditures it is proved that a sufficient condition for existence is that the government expenditures should take the form of cash transfers to consumers rather than being used to provide a government good

the marginal welfare cost of public funds theory and estimates abstract we derive a general analytic formula for the marginal welfare cost mwc of public funds without imposing restrictive assumptions on preferences or technologies the framework encompasses the various special cases previously considered and reconciles the disparities among the reported estimates of mwc unresolved differences in existing estimates are fully explained by appropriate interpretations of intended thought experiments and alternative assumptions about the elasticity of labor supply with respect to public spending further progress in measuring mwc requires empirical estimation of labor supply functions that include government spending as an explanatory variable

financial intermediation as a beliefs bridge between optimists and pessimists this paper proposes a new framework for understandingnancial intermediation in contrast to previous research we consider a setting in which intermediaries possess no inherent information processing or monitoring advantages instead in an economy with overly optimistic entrepreneurs who require funding from overly skeptical pessimistic investors we show that intermediaries can arise endogenously in such a setting only a rational intermediary will be su ciently optimistic tond it worthwhile to invest in a technology for screening entrepreneurs projects and yet be pessimistic enough to use this technology our framework produces implications consistent with heretofore unexplained stylized facts and a number of others which are as of yet untested

credit default swaps has the gfc influenced perceptions of their utility for banks credit default swaps cdss are considered as one of the most versatile financial innovations of the 21st century since its inception the credit derivatives market has grown to a peak of 64 trillion in 2008 in terms of gross notional values cont 2010 however after the onset of the gfc this market has decreased to a large extent while there is evidence that promotes the risk reduction properties of cdss there is a growing body of research post gfc that identifies destabilising effects of these instruments in this paper i review the relevant scholarly literature and provide evidence of how the views on cdss have changed post gfc due a deeper investigation of issues such as systemic risk regulatory arbitrage information asymmetry and risk taking among others in the banking industry this paper provides a survey of the literature of views for and against the use of cdss during pre and post gfc periods and finally concludes that in comparison to the pre gfc period post gfc there is a significant increase in the literature that highlights the detrimental nature of cdss

some models for estimating technical and scale inefficiencies in data envelopment analysis in management contexts mathematical programming is usually used to evaluate a collection of possible alternative courses of action en route to selecting one which is best in this capacity mathematical programming serves as a planning aid to management data envelopment analysis reverses this role and employs mathematical programming to obtain ex post facto evaluations of the relative efficiency of management accomplishments however they may have been planned or executed mathematical programming is thereby extended for use as a tool for control and evaluation of past accomplishments as well as a tool to aid in planning future activities the ccr ratio form introduced by charnes cooper and rhodes as part of their data envelopment analysis approach comprehends both technical and scale inefficiencies via the optimal value of the ratio form as obtained directly from the data without requiring a priori specification of weights and or explicit delineation of assumed functional forms of relations between inputs and outputs a separation into technical and scale efficiencies is accomplished by the methods developed in this paper without altering the latter conditions for use of dea directly on observational data technical inefficiencies are identified with failures to achieve best possible output levels and or usage of excessive amounts of inputs methods for identifying and correcting the magnitudes of these inefficiencies as supplied in prior work are illustrated in the present paper a new separate variable is introduced which makes it possible to determine whether operations were conducted in regions of increasing constant or decreasing returns to scale in multiple input and multiple output situations the results are discussed and related not only to classical single output economics but also to more modern versions of economics which are identified with contestable market theories

nature of transfers income tax function and empirical estimation of elasticity of taxable income for brazil abstractthis article aims to estimate the elasticity of taxable income eti taking into account the nature of transfers and their use as a redistribution package involving cash and in kind transfers to households in brazil our contributions are twofold first we provide a simple model with balanced budget government that reveals the role played by cash and in kind transfers on the labour supply and income tax revenues thereof next in order to estimate eti in the presence of cash and in kind transfers brazilian population surveys pesquisa nacional por amostra de domicilios pnad are used to explore a limited tax reform that was implemented between 1997 and 1998 this reform only affected the higher income tax bracket our findings suggest that in kind cash transfers are positively negatively associated with reported taxable income and precise estimation of eti requires estimates of both types of transfers last we estimate the eti for brazil in the range from 0 4 to 1 3 not different fro

a critical review of contagion risk in banking the recent financial crisis has focused the attention of scholars and policymakers on how to improve financial stability through better macro prudential regulation and supervision in this paper we compare the existing theoretical and empirical literature on contagion through the banking system it is argued that the structure of the interbank market the size of banks the linkages among them the level of correlation of their investments and the transparency of the regulator are key factors in determining the possibility of contagion we discuss the different findings and present avenues for future research

deposit insurance and wealth effects the value of being too big to fail this paper investigates the effect on bank equity values of the comptroller of the currency s announcement that some banks were too big to fail and that for those banks total deposit insurance would be provided using an event study methodology we find positive wealth effects accruing to tbtf banks with corresponding negative effects accruing to non included banks we demonstrate that the magnitude of these effects differed with bank solvency and size we also show that the policy to which the market reacted was that suggested by the wall street journal and not that actually intended by the comptroller the role of deposit insurance has become a topic of increasing debate advocates argue that by removing the incentive to run deposit insurance protects individual financial institutions from instability in the intermediation process thereby providing stability to the financial system as a whole 1 the recent rise in bank failures and the concomitant crises in the s l industry however demonstrate that this stability is not guaranteed moreover critics note that deposit insurance may introduce incentive problems and wealth effects into the financial system both of which can impede the effective functioning of any deposit insurance system these problems have prompted concern about the structure of the current deposit insurance system and have led to numerous proposals regarding its restructuring 2 this paper investigates one aspect of this debate by analyzing the effect on bank equity values of the policy decision to insure completely some banks but not others specifically in september 1984 the comptroller of the currency testified before congress that some banks were simply too big to fail tbtf and that for those banks total deposit insurance would be provided while not explicitly naming the banks the comptroller admitted that this policy would apply to the eleven largest banks using an event study methodology we analyze

economic cost scale efficiency and competitive viability in banking this paper addresses the issue of the competitive viability of banks of different scales and scopes of operation and the implications that this may have for the evolving structure of the banking and financial services industry unlike previous papers this paper is the first to include both production and opportunity costs in an empirical evaluation of bank efficiency no consistent evidence is reported to suggest that banking organizations can achieve further gains in either production or economic efficiency by expanding beyond 2 billion dollars of total assets thus it is likely that smaller less diversified banking organizations will remain competitively viable copyright 1996 by ohio state university press

tax effects versus budget effects on labor supply this paper analyzes the effects on labor supply of parallel changes in taxes and public spending of various types a number of important recent developments in the labor supply behavior of households are highlighted by such a study of various types of budget effects rather than isolated tax effects this comes out in particular when considering cross substitution effects on labor supply of changes in public spending on goods and services or of the subsidization of goods and services provided by private markets moreover the income effects of tax changes are often mitigated or possibly even removed by the income effects of the accompanying expenditure changes

costly monitoring financial intermediation and equilibrium credit rationing abstract this paper establishes a link between equilibrium credit rationing and financial intermediation in a model with asymmetrically informed lenders and borrowers costly monitoring and investment project indivisibilities intermediation is shown to dominate borrowing and lending between individuals and these financial intermediaries exhibit several of the important features of intermediaries as we know them equilibrium interest rates and the aggregate quantity of loans respond quite differently to changes in taste and technology parameters depending on whether or not there is rationing in equilibrium

on the possibility of an inverse relationship between tax rates and government revenues abstract when arthur laffer and other supply side advocates plot total tax revenue as a function of a particular tax rate they draw an upward sloping segment called the normal range followed by a downward sloping segment called the prohibitive range a brief literature review indicates that tax rates on the prohibitive range in theoretical and empirical models have been the result of particularly high tax rates high elasticity parameters or both the labor tax rate which maximizes total revenue for example will depend on the assumed labor supply elasticity this paper introduces a new curve which summarizes the tax rate and elasticity combinations that result in maximum revenues separating the normal area from the prohibitive area a general purpose empirical u s general equilibrium model is used to plot the laffer curve for several elasticities and to plot the newly introduced curve using the labor tax example results indicate that the u s could conceivably be operating in the prohibitive area but that the tax wedge or labor supply elasticity would have to be much higher than most estimates would suggest

interest rate derivatives and bank lending abstract we study the relationship between bank participation in derivatives contracting and bank lending for the period 30 june 1985 through the end of 1992 since 1985 commercial banks have become active participants in the interest rate derivative products markets as end users or intermediaries or both over much of this period significant changes were made in the composition of bank portfolios we find that banks using interest rate derivatives experience greater growth in their commercial and industrial c i loan portfolios than banks that do not use these financial instruments this result is consistent with the model of diamond review of economic studies 51 1984 393 414 which predicts that intermediaries use of derivatives enables increased reliance on their comparative advantage as delegated monitors

size and performance of banking firms testing the predictions of theory abstract in recent years two important literatures on the theory of banking firms have developed one examines the economic functions of banks in environments in which agents are asymmetrically informed another considers the incentive effects moral hazard resulting from deposit insurance both theories make predictions about the relation between banking firm size and performance an empirical analysis of large bank holding companies investigates measures of market valuation and risk of failure limited support is provided for either set of theoretical predictions

disproportional control rights and the governance role of debt we examine the governance role of debt in the context of u s based dual class ownership structures we hypothesize that the use of debt alleviates the conflict between shareholder classes by balancing the power of controlling insiders we document that dual class firms have higher leverage and a greater propensity to issue private debt they also more frequently use cash sweeps and performance based covenants dual class firms with greater agency conflicts and a greater need to access the capital market appear to rely more extensively on debt these findings are consistent with controlling insiders bonding against the agency costs associated with dual class ownership the governance role of debt is further corroborated by the valuation effect of debt for dual class companies private debt issuances trigger greater positive market reactions to the inferior dual class stock in relation to both the superior dual class stock and a matched sample of single class firms further leverage attenuates the previou

consistent weight restrictions in data envelopment analysis abstract it has recently been shown that the incorporation of weight restrictions in models of data envelopment analysis dea may induce free or unlimited production of output vectors in the underlying production technology which is expressly disallowed by standard production assumptions this effect may either result in an infeasible multiplier model with weight restrictions or remain undetected by normal efficiency computations the latter is potentially troubling because even if the efficiency scores appear unproblematic they may still be assessed in an erroneous model of production technology two approaches to testing the existence of free and unlimited production have recently been developed computational and analytical while the latter is more straightforward than the former its application is limited only to unlinked weight restrictions in this paper we develop several new analytical conditions for a larger class of unlinked and linked weight restrictions

corporate governance of banks a survey this paper reviews the empirical literature on the corporate governance of banks we start by highlighting the main differences between banks and nonfinancial firms and focus on three characteristics that make banks special i regulation ii the capital structure of banks and iii the complexity and opacity of their business and structure next we discuss the characteristics of corporate governance in banks and how they differ from the governance of nonfinancial firms we then review the evidence on three governance mechanisms i boards ii ownership structures and iii executive compensation our review suggests that some of the empirical regularities found in the literature on corporate governance of nonfinancial institutions such as the positive negative association between board independence size and performance do not hold for banks also existing work provides no conclusive results regarding the relationship between different governance mechanisms and various measures for banks performance we discuss potential explanations for these mixed results

some analytics of the laffer curve abstract it is shown that in a general equilibrium model with one private good one public good labour and an income tax certain widely assumed properties of the laffer curve do not necessarily hold for well behaved functional forms it may not be continuous and may not have an interior maximum its slope depends on technology as well as on the tax elasticity of labour supply for certain technologies a more negative elasticity may imply a more positive slope moreover the relevant tax elasticity is a general equilibrium one which may differ in sign from the widely quoted partial equilibrium one

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

the marginal cost of raising tax revenue and redistributing income we present analytic formulas for calculating marginal welfare costs when taxes are levied against the wages of a heterogeneous population of households and marginal tax revenue finances either the supply of a public good or lump sum transfers the formulas are applied to explain the wide discrepancy between estimates of marginal welfare costs for redistribution previously obtained through computer simulation procedures our calculations reveal that these procedures introduced lump sum transfers that were not specified as part of the reforms to be simulated but explain most of the differences between their estimates we also show that welfare cost estimates are quite sensitive to the elasticity of labor supply with respect to exhaustive public spending

on the marginal welfare cost of taxation this paper develops a rigorous partial equilibrium analysis of the determinants of margin al welfare cost mwc of taxes on labor earnings it shows that four key parameters interact to determine the magnitude of mwc using aggregate data and plausible ranges of values for the parameters mwc can vary from under 10 percent to more than 300 percent of marginal tax revenue intermediate parameter values sugge st mwc is in the 25 50 percent range however the more extreme estimates cannot be ruled out on the basis of available evidence suggesting that mwc cannot yet be copyright 1987 by american economic association

tobin s q and the structure performance relationship comment the exchange of comments between william shepherd and michael smirlock thomas gilligan and william marshall this review december 1986 raised two key points that remain unresolved the first point is whether tobin s q ratio a firm s financial market value divided by replacement cost of its assets is a better measure of firm performance than accounting rates of return the second point of contention is whether superior performance however measured can be attributed to efficiency rather than market power this paper offers further clarification on both of these points in section i the performance measure choice is shown to be influenced by fundamental differences between finance and economics in section ii the structure performance model employed by smirlock gilligan and marshall hereafter sgm and shepherd is shown to be a special case of a more general model allowing for a dependence of the market share performance relationship on the concentration ratio the same data from the original study by sgm 1984 are used in section iii to provide a comparison of sgm s findings with empirical results from an alternative specification of the structure performance model this comparison suggests that attributing superior firm performance exclusively to efficiency is not well founded concluding remarks are found in section iv

optimal managerial contracts and equilibrium security prices recent developments in economic theory have focused attention on efficient methods for providing incentives within a corporation especially to top management jensen meckling 12 have examined some implications of incentive or agency problems for corporate finance in this paper we combine a simple model of security market equilibrium with that of an optimal managerial incentive contract using results of harris raviv 8 and holmstrom 9 we provide a rationale for including security prices in the managerial incentive contracts of publicly held firms in this model we also show that non systematic diversifiable risks will be considered in the capital budgeting decisions of a managerial firm operated in the interests of its stockholders this is in contrast to the implication of the arbitrage pricing theory a similar result follows from the capital asset pricing model which abstracts from incentive problems and suggests that only systematic risks ought to be considered the optimal contract model of the corporation takes the following view of the firm since decision makers within a firm are not sole owners of the business but employed agents the decisions which they make depend on the incentives which the organization provides these incentives are embodied explicitly in employment contracts and implicitly through the threat of dismissal or effect on reputation the contract whether explicit or not describes the decision maker s anticipation of the consequences to him conditional on various observable outcomes these outcomes are used to provide information useful in determining whether he did his job properly in the simplest optimal contract scenario there is a single principal and a single agent whose decision concerns the level of effort he expends the level of effort affects the level of output of the firm but not unambiguously because the output is also governed by other stochastic elements as a result some information about the agent s level of effort can be inferred

tax rates and labor supply in fiscal equilibrium tax rates and labor supply in fiscal equilibrium i introduction if the government changes the tax on wage income what happens to aggregate labor supply this question is at the core of debates between proponents of supply side and keynesian approaches to government fiscal policy it is unfortunate therefore that previous attempts to resolve the issue have obscured decisive assumptions regarding the preference relation between leisure and public spending one argument exposited recently by gwartney and stroup 1983 1986 and ehrenberg and smith 1988 179 80 descends from an older literature represented by the works of friedman 1949 1954 goode 1949 scitovsky 1951 and bailey 1954 and emphasizes the importance of a balanced budget framework for addressing the question this approach reveals the presence of an income effect caused by the change in government spending that must accompany the tax change at optimum according to this view this income effect exactly offsets the income effect of the tax change so that only the substitution effect of the tax remains as a consequence a balanced budget increase in the wage tax unambiguously decreases economy wide labor supply provided the increase in public spending is valued the same as the forgone private spending a different approach was initiated by winston 1965 and subsequently elaborated upon by lindbeck 1982 fullerton 1982 hanson and stuart 1983 bohanon and van cott 1986 and gahvari 1986 this approach stresses the importance of the preference relation between public spending and private spending rather than the role of the public spending income effect in determining the change in aggregate labor supply as a special example gahvari 1986 assumes a preference structure which implies that public spending does not have any influence on labor supply so there is only the partial equilibrium effect of the tax however the general conclusion of this line of reasoning is that the theoretical ambiguity of the labor supply response arises from both tax and spending effects in this paper a simple formal model is used to develop a careful accounting of the various income and substitution effects the model is sufficiently general to permit a rigorous comparison of earlier studies and to expose implicit assumptions responsible for their conclusions we show that the two approaches outlined above are associated respectively with the focal cases of compensated independence and ordinary independence between leisure and public spending the pan of the paper is as follows section ii contains a model of labor supply in the presence of wage taxation and public spending in section iii the effect on aggregate labor supply of a balanced budget change in wage taxation is analyzed section iv provides an interpretation of several previous analyses of these issues section v contains a summary of our results ii the model consider an economy with n identical consumers who derive utility from leisure l a pure private good x which serves as numeraire and a publicly provided good z the utility function u l x z is assumed to be twice continuously differentiable and strictly quasi concave everyone is endowed with t units of time which are allocated either to labor market work or leisure nonmarket activities the marginal product of labor in producing the private good is the constant real gross of tax wage rate w because agents are identical we can confine attention to allocations of equal consumption as a consequence the production possibilities frontier assumed to be linear can be expressed in per capita terms as wl x p n z wt 1 where p is the constant marginal cost of z with identical agents and only two goods not publicly provided it may be assumed without loss of generality that public spending is financed by a wage tax with constant marginal and average ad valorem rate t

the economic effects of foreign bank presence evidence from the philippines abstract this study examines the economic effects of the liberalization of foreign bank entry in the philippines from 1990 to 2006 the findings provide strong evidence on the dominance of competition effects from foreign bank presence which lead to the reduction in the profitability and overhead costs of domestic commercial banks these findings which reveal that both the actual market penetration and mere presence of foreign banks seem to exert competitive pressure to domestic banks imply that foreign banks may serve as an effective competitive force reducing the excess profits earned by domestic banks and compelling domestic banks to update their production technologies and techniques to improve their cost efficiency from a policy perspective the findings on competition effects of foreign banks in the domestic banking system justify the liberalization of foreign bank entry in the philippines the main findings demonstrate that the goal of banking liberalization in transforming domestic banks to be more competitive and efficient works considerably well in the case of the philippines aside from the policy of easing the entry of foreign banks bank specific conditions can have significant impact on the performance of domestic banks therefore a sustained improvement in the efficiency of domestic commercial banks requires not only liberalizing the entry of foreign banks but also on continued strengthening of domestic prudential regulation and supervision on the commercial banking system

family labor supply with taxes over the period 1960 1983 the proportion of federal tax revenue raised by taxation of labor supply has risen from 57 77 percent in this paper we specify and estimate a model of family labor supply which treats both federal and state taxation husbands and wives labor supply are treated jointly rather than in aseparate manner as in previous research a method to calculate the virtual wage for nonworking spouses is used within a utility maximizing framework to treat correctly the joint family labor supply decision joint family efforts are found to be important the efficiency cost deadweight loss of labor taxation is estimated to be 29 6 of tax revenue raised the effect of the new 10 deduction to ease the marriage tax for working spouses leads to a prediction of 3 8 increase in wives labor supply and a 9 decrease in husbands labor supply overall taxes paid are predicted to decrease by 3 4 this abstract was borrowed from another version of this item

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

what is the impact of bankrupt and restructured loans on japanese bank efficiency the japanese banking system provides a distinctive platform for the examination of the long lasting effect of problem loans on efficiency we measure technical efficiency by modifying a translog enhanced hyperbolic distance function with two undesirable outputs identified as problem loans and problem other earning assets our unique database allows us to distinguish between bankrupt and restructured loans to investigate the underlying causality between these loans and efficiency from the flexible panel vector autoregression specification primary results reveal that bankrupt loans have a positive impact on efficiency related to the moral hazard skimping hypothesis with the causality originating from bankrupt loans in contrast findings for the relationship between restructured loans and efficiency support the bad luck hypothesis

labor supply and tax rates reply the comments of firouz gahvari and of cecil bohanon and t norman van cott provide useful extensions of our earlier analysis nonetheless our central point remains intact the traditional labor leisure analysis is invalid because it ignores the effects of changes in government spending on individual welfare gahvari points out that in the case of public goods the linkage between changes in tax rates and labor supply is more complex than we implied individuals unable in the large number case to transform leisure into public goods will be affected differently when the government provides a public good rather than an income transfer in gahvari s world where government goods are irrelevant to all private decisions complete separability in the utility functions and no ability to purchase public goods privately the quantity of government goods can be safely ignored in the analysis of private decisions the decision proceeds as it would if tax revenues were totally wasted even though the citizens total utility is assumed constant when tax revenues change with changes in government goods exactly offsetting the utility impacts of the change in private goods however we think it is misleading to label the ambiguously signed element beyond the substitution effect as an income effect how can there be an income effect when total utility remains constant as the quotes cited by gahvari from our initial paper p 447 illustrate this is not the income effect envisioned by the traditional work leisure analysis which refers to a change in standard of living utility and reflects the notion that a tax cut will encourage individuals to work less consume more leisure by giving them a higher standard of living through more after tax pay implicitly this view ignores the negative impact on living standards associated with the reduction in the supply of government provided goods or income transfers gahvari recognizes that when government goods replace private goods such as public education medical services food stamps or cash and ignoring any cross elasticities our original analysis stands and there is only the substitution effect bohanon and van cott make another refinement pointing out some secondary effects of government s tax transfer activity while changes in tax rates and in government provided goods will influence the individual s budget constraint or ability to trade off among goods a complete analysis must also account for the fact that any such shift will move the individual into a new region of his indifference surface his willingness to trade off among the goods may well change the individual s view of the substitutability or complementarity among government provided goods private goods and leisure becomes relevant if the government good is strongly enough complementary to leisure and or substitutable for private goods the standard substitution effect could indeed be overcome returning to our original paper we reiterate its central point the income effect component of traditional work leisure analysis for an individual ignores the individual s utility derived foregone from increased decreased government spending accompanying changes in revenues to treat that indi

when does a decrease in a distortion increase welfare abstract with non identical individuals when does decreasing a distortion increase welfare minimizing the tax rate is efficient as long as pre tax income is decreasing in the tax rate this condition is likely to hold for typical methods of financing public goods

bank competition and financial stability much ado about nothing the theoretical literature gives conflicting predictions on how bank competition should affect financial stability and dozens of researchers have attempted to evaluate the relationship empirically we collect 598 estimates of the competition stability nexus reported in 31 studies and analyze the literature using meta analysis methods we control for 35 aspects of study design and employ bayesian model averaging to tackle the resulting model uncertainty our findings suggest that the definition of financial stability and bank competition used by researchers influences their results in a systematic way the choice of data estimation methodology and control variables also affects the reported coefficient we find evidence for moderate publication bias taken together the estimates reported in the literature suggest little interplay between competition and stability even when corrected for publication bias and potential misspecifications this abstract was borrowed from another version of this item

inflation targeting is it to blame for banking system instability abstract in light of the financial crisis the practice of inflation targeting it has been blamed for authorities failure to respond to the increase in financial systemic risk and to the development of asset bubbles however utilizing a rich database containing nearly 5500 commercial banks from 70 countries among which 22 are it for the period 1998 2012 this paper argues that on average inflation targeting national banking systems i are more stable ii possess sounder systemically important banks and iii are less distressed than or at least as distressed as other banks during periods of global liquidity shortages our results are robust to a series of tests such as when we compare countries with the same legal origins or control for the delegation of bank supervision responsibility to bodies other than the central bank overall we conclude that it cannot be blamed for contributing to financial fragility

basel iii leverage ratio requirement and the probability of bank runs abstract a new argument for the basel iii leverage ratio requirement is proposed the need to limit the risk of a bank run when there is imperfect information on the value of a bank s assets in addition to screening and monitoring borrowers banks provide liquidity insurance with the supply of short term deposits withdrawable on demand the maturity mismatch creates the risk of a disorderly bank run which can be exacerbated by imperfect information about the value of bank assets it is shown in a stylized basel iii framework that capital regulation should incorporate a liquidity risk component credit risk diversification and or a reduced probability of loan default which lead to a reduction of basel iii regulatory capital will increase the probability of a bank run the leverage ratio rule puts a floor on the basel iii risk weighted capital ratio allowing the limitation of such a risk

do bank loan relationships still matter james 1987 and lummer and mcconnell 1989 find that during the 1970s and 1980s the market responded positively to announcements of bank lending agreements however many of the advantages associated with bank lending relationships have largely disappeared since the 1980s due to financial system changes and greater availability of and less costly financial information we find that bank loan announcements produced positive abnormal returns in the 1980s but by the latter part of our sample period those announcement returns disappear entirely we do find that bank loan relationships may still be valuable to smaller poorer performing firms or during periods of high credit risk spreads

endogenous bank risk and efficiency we develop a framework to incorporate bank risk as measured from the variance of profits or returns within a model of frontier efficiency our framework follows the premise that risk is endogenously related to efficiency we estimate our model using panel data for u s banks and bayesian techniques we show that excluding risk from the efficiency model significantly biases the efficiency estimates and the ranking of banks according to their competitive advantage we also demonstrate that there is a negative risk efficiency nexus with causality running both ways while our estimates of risk are fully consistent with the developments in the banking industry over the period 1976 2014

labor supply taxes and government spending a microeconometric analysis the effect of government spending on labor supply behavior is critical to predicting the balanced budget effect of income taxes and to estimating the marginal social cost of public funds yet its very existence not to mention direction and magnitude has not been empirically investigated this research estimates a labor supply function that incorporates income taxation and government spending using microeconomic data for men and women the empirical results suggest that public sector spending may have a significant effect on labor supply thereby leading to estimates of the marginal social cost of public funds that differ from those typically calculated

optimal weights in dea models with weight restrictions abstract according to a conventional interpretation of a multiplier dea model its optimal weights show the decision making unit under the assessment denoted dmu o in the best light in comparison to all observed dmus for multiplier models with additional weight restrictions such an interpretation is known to be generally incorrect specifically if weight restrictions are linked or nonhomogeneous and the meaning of optimal weights in such models has remained unclear in this paper we prove that for any weight restrictions the optimal weights of the multiplier model show dmu o in the best light in comparison to the entire technology expanded by the weight restrictions this result is consistent with the fact that the dual envelopment dea model benchmarks dmu o against all dmus in the technology and not only against the observed dmus our development overcomes previous concerns about the use of weight restrictions of certain types in dea models and provides their rigorous and meaningful interpretation

interest rate derivatives at commercial banks an empirical investigation abstract i analyze the effects of bank characteristics and macroeconomic shocks on interest rate risk management behavior of commercial banks my findings are consistent with hedging theories based on cost of financial distress and costly external financing banks with higher probability of financial distress manage their interest rate risk more aggressively both by means of on balance sheet and off balance sheet instruments as compared to the derivative users the derivative non user banks adopt conservative asset liability management policies in tighter monetary policy regimes finally i show that the derivative non user bank s lending volume declines significantly with the contraction in the money supply derivative users on the other hand remain immune to the monetary policy shocks my findings suggest that a potential benefit of derivatives usage is to minimize the effect of external shocks on a firm s operating policies

credit risk transfer in u s commercial banks what changed during the 2007 2009 crisis abstract following the debate on the role of credit risk transfer crt in exacerbating the 2007 2009 crisis this paper investigates the usage and effects of loan sales securitization and credit derivatives in u s commercial banks over the last decade with special emphasis on the financial crisis we find that in times of severe funding constraints the need to raise financial resources becomes the principal incentive behind crt we document some beneficial effects of crt on the economy since the funds released through crt are subsequently invested by banks to sustain credit supply also in recession however we report higher overall riskiness in banks that engage intensively in loans sales and securitization which translates into higher default rates during the crisis interestingly the benefits and drawbacks of crt are much stronger for loan sales and securitization than for credit derivatives

size and earnings volatility of us bank holding companies abstract we examine whether bank earnings volatility depends on bank size using quarterly data for bank holding companies in the united states for the period 1995q1 2010q3 and controlling for the quality of management leverage and diversification we find that bank size reduces return volatility however the effect is non linear when bank size exceeds a certain threshold about us 5 billion size is positively related to earnings volatility the recent financial crisis decreased the threshold beyond which the impact of size on volatility turns positive

the risk of financial intermediaries this paper reconsiders the formal estimation of bank risk using the variability of the profit function in our model point estimates of the variability of profits are derived from a model where this variability is endogenous to other bank characteristics such as capital and liquidity we estimate the new model on the entire panel of us banks spanning the period 1985q1 2012q4 the findings show that bank risk was fairly stable up to 2001 and accelerated quickly thereafter up to 2007 we also establish that the risk of the relatively large banks and banks that failed in the subprime crisis is higher than the industry s average thus we provide a new leading indicator which is able to forecast future solvency problems of banks

is financial inclusion good for bank stability international evidence abstract financial inclusion has become an important public policy priority following the recent global financial crisis yet we know very little of how it impacts soundness of the providers of financial services using an international sample of 2635 banks in 86 countries over the period 2004 12 we find that higher level of financial inclusion contributes to greater bank stability the positive association is particularly pronounced with those banks that have higher customer deposit funding share and lower marginal costs of providing banking services and also with those that operate in countries with stronger institutional quality the results are robust to instrumental variables analysis controlling for bank fixed effects alternative measures of financial inclusion among several other robustness tests our results highlight that the importance of ensuring inclusive financial system is not only a development goal but also an issue that should be prioritised by banks as such a policy drive is good for their stability

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

returns to scale in convex production technologies the notion of returns to scale rts is well established in data envelopment analysis dea in the variable returns to scale production technology the rts characterization is closely related to other scale characteristics such as the scale elasticity most productive scale size mpss and global rts types indicative of the direction to mpss in recent years a number of alternative production technologies have been developed in the dea literature most of these technologies are polyhedral and hence are closed and convex sets examples include technologies with weakly disposable undesirable outputs models with weight restrictions and production trade offs technologies that include several component production processes and network dea models for most of these technologies the relationship between rts and other scale characteristics has remained unexplored the theoretical results obtained in this paper establish such relationships for a very large class of closed convex technologies of which polyhedral technologies are an important example

local versus international crises and bank stability does bank foreign expansion make a difference abstractwe investigate the impact of global and local crises on bank stability in the mena region and examine the effect of owning bank subsidiaries in other countries we consider banks that experienced both types of crises during our sample period our findings highlight a negative impact of the global financial crisis of 2007 2008 on bank stability but on the whole no negative impact of the local crisis a deeper investigation shows that owning bank subsidiaries outside the home country is a source of increased fragility during normal times yet a source of higher stability during the local crisis but not during the international crisis moreover owning foreign subsidiaries in one or two world regions is insufficient to neutralize both types of crises while being present in three or more regions is more stabilizing during a local crisis but also more destabilizing during an international crisis our findings contribute to the literature examining bank stability and have several policy implications

on the positive role of financial intermediation in allocation of venture capital in a market with imperfect information this paper develops a theory of financial intermediation that highlights the contribution of intermediaries as informed agents in a market with imperfect information we consider a venture capital market where the entrepreneurs select the qualities of projects and their perquisite consumptions about which the investors are imperfectly informed it is shown that when all investors have positive search costs the entrepreneurs are induced to offer the unacceptable inferior projects lemons only and the investors will not enter the venture capital market but put their funds in other low return investments an undesirable allocation of resources beginning with an initial undesirable situation the financial intermediaries may evolve as informed agents that induce a pareto preferred allocation leading the investors to a higher welfare state we focus our analysis on the existence of intermediation equilibra when the market for intermediation services is competitive the distribution of returns on projects the fees charged by intermediaries and the fraction of institutional holdings are all endogenous in equilibrium it is shown that i there cannot be a competitive intermediation equilibrium with very high institutional holdings and ii in other cases multiple equilibra may exist but the one with the highest institutional holdings dominates the others in a pareto sense

did risk based capital allocate bank credit and cause a credit crunch in the united states this paper examines the reallocation of bank credit from loans to securities in the early 1990s using data on virtually all u s banks from 1979 to 1992 the authors investigate implementation of risk based capital and other regulatory and nonregulatory changes as possible causes of a supply driven credit crunch the main empirical implication of these credit crunch hypotheses that the reallocation of credit would be most associated with low capital high risk banks generally is not consistent with the data much of the reallocation is associated with demand side factors but it is difficult to differentiate cleanly among these factors copyright 1994 by ohio state university press

bank competition and financial stability in asia pacific the impact of bank competition on financial stability has been a focus of academic and policy debate over the last two decades and particularly since the 2007 08 global financial crises beck 2008 oecd 2011 under the traditional competition fragility view banks cannot earn monopoly rents in competitive markets and this results in lower profits capital ratios and charter values this makes banks less able to withstand demand or supply side shocks and encourages excessive risk taking marcus 1984 alternatively the competition stability view suggests that competition leads to greater stability a less competitive banking market may lead to more risk taking if the big banks are deemed too important to fail and as such obtain implicit or explicit subsidies via government safety nets mishkin 1999 in addition banks with more market power tend to charge higher loan rates which may induce borrowers to assume greater risk leading to greater default in competitive banking markets loan rates are lower too big to fail issues and safety net subsidies are smaller and this results in a positive link between bank competition and stability boyd and de nicolo 2005 it could also be the case as noted by martinez miera and repullo 2010 that bank competition and stability are linked in a non linear manner and in a similar vein berger et al 2009 argue that competition and concentration may coexist and can simultaneously induce stability or fragility

some stronger measures of risk aversion in the small and the large with applications the arrow pratt measures of risk aversion for von neumann morgenstern utility functions have become workhorses for analyzing problems in the microeconomics of uncertainty they have been used to characterize the qualitative properties of demand in insurance and asset markets to examine the properties of risk taking in taxation models and to study the interaction between risk and life cycle savings problems to name just a few applications equally importantly they have generated the linear risk tolerance class of utility functions which has provided canonical examples in such diverse areas as portfolio theory and the theory of teams despite these successes there have been a number of areas for which the results have been weaker than hoped it is natural to use the risk aversion measures to compare the behavior of individuals in risky choice situations for example consider the individual portfolio choice problem in a two asset world with a riskless asset and a risky asset if individual a has a uniformly higher arrow pratt coefficient of risk aversion than individual b then b will always choose a portfolio combination with more wealth invested in the risky asset but suppose that both assets are risky now there is no obvious sense in which the more risk averse individual can be said to hold a less risky portfolio but it seems strange that such a simple alteration should destroy the analytics which support the basic intuition similarly consider the basic insurance problem if one individual a is more risk averse than another b in the arrow pratt sense it follows that a will pay a larger premium to insure against a random loss than will b typically though an individual evaluates partial rather than total insurance that is only some gambles can be insured against and others must be retained in this case even when the gambles which are retained are independent from those which are insured it is no longer true that the individual whose arrow pratt measure of risk aversion is higher will pay a larger insurance premium the situation is no better when we consider comparative statics exercises for a single individual decreasing absolute risk aversion in the sense of arrow and

derivatives holdings and market values of u s bank holding companies abstractwe examine the impact of derivatives held by us bank holding companies on their market valuations over the period 2000 to 2010 by using bank level data with detailed information on the notional amounts of derivative positions according to holding purposes and underlying asset types our regression analyses provide three main findings first derivative instruments held for hedging rather than trading purposes contribute to enhancing market values second the positive effects exhibit nonmonotonic patterns indicating that excessive amounts of derivatives holdings deteriorate market values third interest rate derivatives are the main source of high valuations

temporal risk and the nature of induced preferences abstract it has been known since the work of h markowitz portfolio selection efficient diversification of investments yale univ press 1959 and j mossin amer econ rev 59 1969 172 174 that even an individual whose underlying preferences satisfy the von neumann morgenstern axioms will not choose over delayed i e temporal risky prospects in a manner which can be modelled as expected utility maximizing since most economically important instances of risk taking insurance real investment agriculture career training involve delayed as opposed to immediately resolved risk the standard use of expected utility theory to model such decisions must be questioned in this paper the technique of generalized expected utility analysis m j machina econometrica 50 1982 277 323 and the theory of support functions r t rockafellar convex analysis princeton univ press 1970 are applied to exactly model and hence determine the nature of preferences over temporal risky prospects

regulations market structure institutions and the cost of financial intermediation this paper examines the impact of bank regulations market structure and national institutions on bank net interest margins and overhead costs using data on over 1400 banks across 72 countries while controlling for bankspecific characteristics the data indicate that tighter regulations on bank entry and bank activities boost the cost of financial intermediation inflation also exerts a robust positive impact on bank margins and overhead costs while concentration is positively associated with net interest margins this relationship breaksdownwhencontrolling for regulatory impediments to competition and inflation furthermore bank regulations become insignificant when controlling for national indicators of economic freedom or property rights protection while these institutional indicators robustly explain cross bank net interest margins and overhead expenditures thus bank regulations cannot be viewed in isolation they reflect broad national approaches to private property and competition

labor supply and tax rates comment in a recent paper in this review 1983 james gwartney and richard stroup g s take issue with what they assert is the widespread view p 447 that because changes in tax rates have a theoretically indeterminate effect on individual labor supply the impact of changing tax rates is also indeterminate at the aggregate level gwartney and stroup suggest for example that if the initial output of public goods is optimal and the government cuts taxes and expenditures by equal amounts the forgone public goods would be valued as highly as the private goods that individuals purchase with their increase in disposable income hence aggregate real income would not rise but remain at its pre tax cut level gwartney and stroup state that under these circumstances a tax cut s impact on aggregate labor supply would not be indeterminate but labor inducing because in the aggregate there is no income effect only a positive substitution effect 1 gwartney and stroup illustrate this point by examining the aggregate labor supply effects of an increase in transfer payments financed by an exactly offsetting increase in income taxes they argue that if the transfer payments are income conditioned this policy would decrease net wage rates for transfer recipients as well as for taxpayers thereby producing work reducing substitution effects for all members of society on the other hand the aggregate change in disposable income in the economy would be zero since by design the expansion in transfers is exactly offset by the increase in taxes they conclude that unless recipients and taxpayers respond differently to a given change in disposable income the income effect of the tax transfer program will leave both the aggregate supply of labor and consumption of leisure unchanged but of course the substitution effect will still be present unambiguously it will induce individuals to work less although how much less is strictly an empirical issue p 450 in this comment we demonstrate that the g s tax transfer illustration and the policy implications drawn from it are highly misleading we first show that the g s conclusions about the relationship between tax rates and labor supply are based upon strong assumptions about the degree of homogeneity in the population and that without these assumptions their conclusions are not guaranteed to hold we then use microsimulation techniques to challenge the impression given by the g s paper that more redistribution must necessarily imply a reduction in the labor supply and output of the economy

tax rates government expenditures and labor supply clarifying the record a central claim of supply side economics is that in general equilibrium the income effect of a change in the income tax rate washes out and only the substitution effect remains in the words of ehrenberg and smith 1985 there would be a substitution effect with no overall income effect and labor supply would increase the aggregate supply of labor curve then must be upward sloping p 160 emphasis in the original although there has been a substantial literature on this subject the literature is sometimes confused in this paper a simple model is used to sort through the literature correct mistaken assertions derive a new result and collect earlier results in a compact way

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

refinancing mfis with market power theory and evidence this paper presents a model of the complete microcredit financing chain investor miv mfi micro borrower in which social minded mivs provide funds only to those mfis which do not exploit their bargaining power towards micro borrowers the mfis with the highest bargaining power do not use miv capital since eschewing their market power is most costly for them consistent with this prediction of the theoretical model we find empirically that the net interest margin as a measure of mfi market power negatively affects the likelihood of using miv finance this lends support to the view that social criteria play an effective role in mivs investment policies thereby also impacting mfis lending behavior
