bank runs liquidity costs and investment distortions abstract in this paper we extend the diamond and dybvig 1983 model of intermediation to study further the conditions under which bank runs can occur and to consider how private parties might adjust to the existence of bank run equilibria we provide weaker necessary conditions for runs we then characterize how banks respond to the possibility of runs in their design of deposit contracts and investment decisions banks might choose to offer contracts that prevent runs but under some conditions the second best contracts will involve accepting some risk of runs in order to achieve higher expected returns from their investments

sustainable de growth mapping the context criticisms and future prospects of an emergent paradigm article i nfo sustainable de growth is both a concept and a social grassroots northern movement with its origins in the fieldsofecologicaleconomics socialecology economicanthropologyand environmentalandsocialactivistgroups this paper introduces the concept of sustainable de growth by mapping some of the main intellectual influences fromthese fields with special focus on the francophone and anglophone thinking about this emergent notion we propose hypotheses pertaining to the appeal of sustainable de growth and compare it to the messages enclosed within the dominant sustainable development idea we scrutinize the theses contradictions and consequences of sustainable de growth thinking as it is currently being shaped by a heterogeneous body of literature and as it interacts with an ample and growing corpus of social movements we also discuss possible future paths for the de growth movement compared to the apparent weakening of the sustainable development paradigm

banking panics information and rational expectations equilibrium this paper shows that bank runs can be modeled as an equilibrium phenomenon we demonstrate that some aspects of the intuitive story that bank runs start with fears of insolvency of banks can be rigorously modeled if individuals observe long lines at the bank they correctly infer that there is a possibility that the bank is about to fail and precipitate a bank run however bank runs occur even when no one has any adverse information extra market constraints such as suspension of convertibility can prevent bank runs and result in superior allocations banking panics were a recurrent phenomenon in the united states until the 1930s they have re emerged as a source of public concern and much theoretical research recently in this paper we provide an information theoretic rationale for bank runs the traditional story is that contagion is an important aspect of bank runs the idea seems to be that when the general public observes large withdrawals from the banking system fears of insolvency grow resulting in even larger withdrawals of deposits in our model some individuals withdraw because they get information that future returns are likely to be low uninformed individuals observing this also have an incentive to liquidate their investments in addition some individuals need to withdraw deposits for other than informationally based reasons thus if the random realization of such a group of individuals is unusually large then the uninformed individuals will be misled and will precipitate a run on the bank the technology is such that a large volume of withdrawals involves liquidation costs consequently runs on the bank do impose social costs a mechanism that may reduce these costs in our model is to suspend convertibility if withdrawals are high however those individuals who need to withdraw their assets for liquidity reasons are worse off ex post our model provides a rationalization for restrictions in demand deposits that were widespread prior to 1929 friedman and schwartz 7 suggest that restrictions of payments ensured

shifting priorities in degrowth research an argument for the centrality of human needs we present an argument for the deprioritization of subjective well being and a prioritization of human needs within degrowth research first we discuss empirical evidence methodological problems and theoretical shortcomings of subjective well being concepts while data for one country over time suggest a flattening of the happiness curve relative to gdp growth cross country comparisons reveal that the richest and most environmentally unsustainable countries are also the happiest methodologically we point to the issue of adaptability a limitation in the use of positional goods is unlikely to be accompanied by short term increases in subjective well being theoretically we question happiness where it helps promote growth and disguise structural relationships of inequality secondly we sketch out an alternative degrowth research agenda oriented at the satisfaction of human needs here doyal and gough s theory of human needs is especially useful due to its systematic account of environmental limits and the policy auditing approach that follows from it finally we illustrate such a needs based research agenda at the example of food by reviewing recent research on the environmental impacts of different diets and kinds of food production and on how these forms compare in terms of scale and land use

inter vivos transfers and exchange most parents divide their bequests equally among their children whereas inter vivos transfers are usually unequal we propose that exchange is better for inducing inter vivos transfers than bequests inter vivos transfers can be adjusted quickly to the amount of care are less costly than writing a will and can be kept secret from other family members and the public the results from national longitudinal data show that as expected if a parent gives any inter vivos transfers she is more likely to give to children who provide informal care informal care has no effect on the equality of intended bequests

is the post fossil era necessarily post capitalistic the robustness and capabilities of green capitalism abstract our central target is to show that capitalism is not only much more robust to crises than presumed by its critics but also features promising capabilities with regard to solving the environmental crisis to elaborate this thesis we analyse how far capitalism can survive given the end of fossil energy carriers and may maintain its productivity under the preconditions of a regenerative energy system in a further step we demonstrate that crises may actually provide the prerequisites of the economy s transformation towards sustainability we argue that especially competitive capitalism as analysed by schumpeter offers excellent preconditions for generating environmental innovations however we will also point out the numerous social problems of green infrastructure projects in the last section we assume that markets alone will not suffice to concertedly solve the global environmental crisis here political action is needed that pools societal forces with regard to the ecological challenges hence specifically promoting desirable innovations the usefulness of state measures is to be judged in correlation to the respective specific national political and economic contexts a generalised opposition to capitalistic social orders disregards the complexity of these contexts and is at danger of omitting decisive determinants of crisis management

identifying barriers toward a post growth economy a political economy view abstract in this paper we take a political economy perspective on barriers that inhibit a transition beyond the growth paradigm that is we frame transition barriers as looming conflicts of interest specifically we investigate potential transition barriers within three case studies first unemployment represents the most commonly cited reason why economic growth is considered indispensable second alternative indicators to gross domestic product gdp have not succeeded in replacing gdp as a standard metric of economic welfare third pension schemes rely on economic growth to offset demographic change in each of these three examples we identify actor interest constellations that foster the status quo of a growth economy we conclude that compensating some of those actors who would presumably be worse off in a post growth economy may be necessary though not sufficient for a transition

insuring banks against liquidity shocks the role of deposit insurance and lending of last resort it has long been recognized that banks simultaneous provision of monitoring and liquidity services is advantageous but leaves them susceptible to liquidity shocks that may culminate in a system failure because a system failure is costly this provides a rationale for adopting arrangements including a lender of last resort and deposit insurance di to insure banks against liquidity shocks these arrangements have proven themselves very successful but they have also been the source of problems researchers have identified some of the main sources of these problems and have suggested ways to improve the design of these arrangements but there are still many issues that remain unaddressed this paper reviews the literature on the two arrangements that most countries have adopted to insure banks against liquidity shocks a lender of last resort and di and compares the design of these arrangements across countries the paper ends with a brief summary of the key lessons learned about the design of these arrangements and the issues related to them that remain unaddressed copyright blackwell publishers ltd 2006

models of banking instability a partial review of the literature abstract this paper critically examines the theoretical literature on banking instability that has followed diamond and dybvig 1983 it explores the extent to which it a explains banking instability within a theoretical context in which financial intermediaries improve on unintermediated markets and b justifies government involvement in the financial intermediation industry it suggests that the literature has yet to provide a satisfactory theoretical basis for banking instability as such since the intermediaries which arise from it are peculiar mutual funds that bear little resemblance to real world banks in addition the paper challenges the widespread belief that this literature provides a sound foundation for government involvement in the industry it suggests that arguments for government intervention are open to objection on various grounds the most important one being that they are inconsistent with the existence of properly motivated financial intermediation in these models

degrowth a missile word that backfires language use and cognition are generally underappreciated topics in ecological economics even if effective communication is essential for social and political impact to challenge the economic growth paradigm the concept and term degrowth has recently been embraced by various activists and scholars drawing on a body of evidence from cognitive science psychology and related fields we argue that using the word degrowth might be disadvantageous in public communications about alternatives to growth we begin by reviewing arguments in favor of the term then we outline three main counterarguments first degrowth has a downward orientation which triggers negative initial feelings due to the basic conceptual metaphor up is good down is bad this puts advocates of an alternative to the growth paradigm in an unfavorable starting position given that subsequent thought will be unconsciously biased by the initial feeling second more conscious reactions are likely to be negative as well because people unfamiliar with the term will mis interpret it as a contraction of the economy even though it is not always meant as such third degrowth repeats and possibly strengthens the growth frame and may activate undesirable frames associated with economic recessions to conclude we briefly discuss alternative terms and summarize key aspects to be considered for more effective communication

bank liquidity and stability in an overlapping generations model in an infinitely repeated version of the diamond and dybvig 1983 model intergenerational transfers enable a bank to achieve interest rate smoothing and to provide depositors with liquidity insurance without diamond and dybvig s assumption of no side trades the bank is subject to runs that may result from either excessive withdrawals or the lack of new deposits the latter cause which cannot occur in diamond and dybvig s one generation model implies that suspension of convertibility may not prevent bank runs government intervention may be necessary to maintain bank stability article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

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

transfer behavior in the health and retirement study measurement and the redistribution of resources within the family recent work by a number of economists has opened a debate about the role played by intergenerational transfers using the new health and retirement study hrs we are better able to address the issues involved contrary to the current literature on bequests we do not find that parents give transfers equally to all children rather we find that in the case of inter vivos transfers respondents give greaterfinancial assistance to their less well off children than to their children with higher incomes financial transfers to elderly parents are also found to be negatively related to the potential recipient s income these results hold both for the incidence of transfers and for the amounts in addition we allow for unobserved differences across families by estimating fixed effect models and find our results to be robust to these specifications a comparison of the hrs transfer data to other survey data demonstrates that the hrs is potentially quite useful for research on transfer behavior

intergenerational transfers and liquidity constraints a growing body of evidence indicates that liquidity constraints could affect a substantial proportion of u s consumers but little is known about why these constraints might exist an important but little explored issue is the relationship between inter vivos intergenerational transfers and liquidity constraints these transfers can ease borrowing constraints empirical transfer patterns match those predicted from a model in which transfers are allocated to liquidity constrained consumers in particular the distinction between current and permanent incomes of potential recipients is a key aspect of private transfer behavior the findings have important implications for our understanding of consumer behavior

capitalist diversity and de growth trajectories to steady state economies abstract growth critical scholarship has done much to both expose the environmentally unsustainable nature of the capitalist growth economies of the overdeveloped part of the world and to develop an alternative vision of a de growth transition leading to a steady state economy however this scholarship fails to adequately take into consideration that if planned de growth actually materialised it would do so in societies that differ considerably from one another and that this would have implications both for the transition processes and the nature of their outcomes in other words not enough importance is ascribed to capitalist diversity and the nature of institutional change in the growth critical literature against this background the purpose of the present article is to make the concrete utopia of de growth scholars and steady state economists more specific by utilising insights from scholarship on capitalist diversity and institutional change on the basis of a typology of different models of capitalism the article suggests that if de growth transitions took place they would take different forms and lead to a variety of types of steady state economies sses to illustrate this point three ideal typical sses are delineated

the strategic bequest motive although recent research suggests that intergenerational transfers play an important role in aggregate capital accumulation our understanding of bequest motives remains incomplete we develop a simple model of strategic bequests in which a testator influences the decisions of his beneficiaries by holding wealth in bequeathable forms and by conditioning the division of bequests on the beneficiaries actions the model generates falsifiable empirical predictions that are inconsistent with other theories of intergenerational transfers we present econometric and other evidence that strongly suggests that bequests are often used as compensation for services rendered by beneficiaries

the threat of rent extraction in a resource constrained future abstract ecological economists aim to transform our economic institutions so that society can flourish within planetary boundaries the central message of this article is that private rent extraction forms a key barrier to the realisation of that goal i define rent as an economic reward which is sustained through control of assets that cannot be quickly and widely replicated and which exceeds proportionate compensation for the labour of the recipient i argue that unless we close opportunities for rent extraction and socialise unavoidable rents our governments will be compelled to pursue output growth regardless of its environmental consequences in order to prevent spiralling inequality and unemployment the positive proposition in this article is that the concept of rent can help us to identify and build democratic support for the institutional transformations necessary to prepare for a resource constrained future measures to reduce and redistribute rentier power could be emancipatory for the poorest in society whilst making more feasible many proposals that have been advocated already in this journal including reduced working hours and resource caps by contrast if environmental protections are introduced before opportunities for private rent extraction are closed we could see intensified rent seeking asset price bubbles poverty and economic insecurity

fear of floating and the external effects of currency unions the introduction of the euro has considerably affected the de facto monetary policy autonomy defined as independence from monetary policy in the key currency areas in countries outside the european currency union ecu using a standard open economy framework we argue that de facto monetary policy autonomy has significantly declined for countries that dominantly trade with the ecu and slightly increased for countries that dominantly trade with the dollar zone the predictions of our model find support in the data we estimate the influence of the bundesbank s ecb s and the fed s monetary policies on various country groups the de facto monetary policy autonomy of both non euro eu members and efta countries declined with the introduction of the euro this effect was slightly stronger for the eu member countries than for efta countries as our theory predicts at the same time the de facto monetary policy autonomy of australia and new zealand vis a vis the us dollar has moderately increased

degrowth through income and wealth caps abstract in the degrowth literature maximum caps on wealth and or income are frequently mentioned among the policy instruments that could support transitions towards ecologically and socially sustainable societies yet an in depth discussion of concrete policy proposals has yet to be initiated to facilitate such a discussion the present paper reviews several proposals for placing caps on wealth and or income some of these proposals consider environmental limits others focus exclusively on social inequality the paper moreover raises various critical issues concerning the introduction of maximum caps on wealth and income in a degrowth context discussing the role of the state the impact on economic growth and the risk of emigration of high skilled employees and capital flight we conclude that while in an ecologically constrained world there is an argument for imposing limits on wealth and income above a certain level it is crucial not to dictate such policies as mere top down measures but to develop and deliberate them in democratic forums

systemic risk and competition revisited abstract this paper revisits the mechanism behind the relation between bank competition and systemic risk i decompose this risk into a component driven by banks commonality with the market and a component arising from other sources of interbank commonality i show that competition is negatively related to the latter this relationship is stronger for more informationally opaque banks financed with a larger share of uninsured sources and in countries with lower deposit insurance coverage the findings are consistent with herding incentives at banks when competition is low

informal insurance arrangements with limited commitment theory and evidence from village economies recent work on consumption allocations in village economies finds that idiosyncratic variation in consumption is systematically related to idiosyncratic variation in income thus rejecting the hypothesis of full risk pooling we attempt to explain these observations by adding limited commitment as an impediment to risk pooling we provide a general dynamic model and completely characterise efficient informal insurance arrangements constrained by limited commitment and test the model using data from three indian villages we find that the model can fully explain the dynamic response of consumption to income but that it fails to explain the distribution of consumption across households

information acquisition and financial contagion abstract this paper incorporates costly voluntary acquisition of information a la nikitin and smith 2007 nikitin m smith r t 2007 information acquisition coordination and fundamentals in a financial crisis journal of banking and finance in press doi 10 1016 j jbankfin 2007 04 031 in a framework similar to allen and gale 2000 allen f gale d 2000 financial contagion journal of political economy 108 1 33 without relying on any unexpected shock to model contagion in this framework contagion and financial crises are the result of information gathering by depositors weak fundamentals and an incomplete market structure of banks it also shows how financial systems entering a recession can affect others with apparently stronger economic conditions contagion finally this is the first paper to investigate the effectiveness of the contingent credit line procedures introduced by the imf at the end of the nineties as a mechanism to prevent the propagation of crises

risk and insurance in a rural credit market an empirical investigation in northern nigeria credit contracts play a direct role in pooling risk between households in northern nigeria repayments owed by borrowers depend on realizations of random shocks by both borrowers and lenders the paper develops two models of state contingent loans the first is a competitive equilibrium in perfectly enforceable contracts the second permits imperfect information and equilibrium default estimates of both models indicate that quantitatively important state contingent payments are embedded in these loan transactions but that a fully efficient risk pooling equilibrium is not achieved the research is based on a year long survey in zaria nigeria conducted by the author

deceleration of economic growth the main course seeking sustainability in developed countries abstract deceleration of economic growth is a characteristic feature of developed countries percentage gross domestic product gdp growth rate in the old organization for economic co operation and development oecd countries has decreased approximately 2 3 times over the last 50 years and countries have managed successfully to adopt this trend the largest reduction of gdp growth rate was observed in countries such as japan where the biocapacity exceedance was the largest in addition the analysis of long term changes of gdp and self reported life satisfaction in developed countries supports easterlin s paradox indicating that richer people do not feel more satisfied with their lives however people from countries with higher per capita gdp feel more satisfied at the same time a statistically insignificant correlation was detected between gdp growth rate and life satisfaction supporting a conclusion that in the developed countries further economic growth does not increase people s well being this suggests that decelerating the rate of economic growth gradually approaching the zero growth steady state phase is the natural way towards sustainability and it does not contradict the well being objective in developed countries especially ones with high biocapacity exceedance

the timing and division of parental transfers to children abstract we find parents divide various assets differently among children inter vivos transfers cash gifts and co residence are made preferentially to poorer children in contrast transfers made at death insurance benefits and wills are awarded to children irrespective of income differences

unique equilibrium in a model of self fulfilling currency attacks even though self fulfilling currency attacks lead to multiple equilibria when fundamentals are common knowledge we demonstrate the uniqueness of equilibrium when speculators face a small amount of noise in their signals about the fundamentals this unique equilibrium depends not only on the fundamentals but also on financial variables such as the quantity of hot money in circulation and the costs of speculative trading in contrast to multiple equilibrium models our model allows analysis of policy proposals directed at curtailing currency attacks

the family as an incomplete annuities market families can self insure against uncertain dates of death through implicit or explicit agreements with respect to consumption and interfamily transfers interfamily transfers need have nothing to do with altruistic feelings they may simply reflect risk sharing behavior of completely selfish family members although family annuity markets are incomplete even small families can substitute by more than 70 percent for perfect market annuities given adverse selection and transaction costs family risk pooling may be preferred to public market annuities in the absence of public annuities these risk sharing arrangements provide powerful incentives for marriage and family formation

a reexamination of the strategic bequest motive this paper investigates the strength of the empirical evidence of the strategic bequest hypothesis proposed by bernheim shleifer and summers 1985 at issue is whether bequests are primarily motivated by a desire to influnce the behavior of potential beneficiaries alternatively bequests may be motivated by altruism or risk aversion in the presence of incomplete annuity and health insurnace markets e g tomes 1981 hurd 1989

wealth inequality and intergenerational links previous work has had difficulty generating household saving behaviour that makes the distribution of wealth much more concentrated than that of labour earnings and that makes the richest households hold onto large amounts of wealth even during very old age i construct a quantitative general equilibrium overlapping generations model in which parents and children are linked by accidental and voluntary bequests and by earnings ability i show that voluntary bequests can explain the emergence of large estates while accidental bequests alone cannot and that adding earnings persistence within families increases wealth concentration even more i also show that the introduction of a bequest motive generates lifetime savings profiles more consistent with the data

a practice approach to the institutionalization of economic degrowth the degrowth literature is rich in critical debate about the unsustainability of the growth economies and in normative envisioning of a transition it lacks analyses on actual materialization and the nature of the change required there have been calls for research that pay attention to institutional constraints and possibilities of implementing a democratic process of sustainable degrowth this paper introduces a practice approach to institutional agency as a fruitful tool for future studies and politics of degrowth the potential of this approach is demonstrated through a struggle between finnish timebanking activists and the tax authorities the cultural and institutional transition promoted by radical bottom up initiatives requires a disruption of existing institutional arrangements some of which may be very persistent and supported by defenders who want to maintain the present institutional order in the case example the authorities and politicians managed to preserve the mechanisms through which certain sanctions are associated with the non compliance of timebanking with the income tax law a practice approach to institutionalization increases our understanding of institutional persistence and makes visible forces that support the present status quo it also enhances understanding of the opposing dynamics and gives tools to engage in more effective efforts to change institutions

ecological economics degrowth and institutional change ecological economics has made great strides in the understanding of how the human economy is embedded in a finite and limited biophysical system however less progress has been made in understanding the internal dynamics of the economy that produce periods of slow growth even in the absence of biophysical constraints the real economy is a complex system replete with myriad positive feedback loops by looking at the economy from a systems perspective ecological economists can better understand the internal dynamics of a market system that lead to the periodic depressions and recessions that characterize the failed growth economy a non growing or declining economy exacerbates formidable economic problems such as unemployment debt and poverty since the middle of the 20th century governments have pursued growth strategies to solve social problems but the age of economic growth is coming to an end driven by its own internal dynamics and by biophysical forces such as climate change and peak oil degrowth implies less and the steady state implies less on a permanent basis ecological economists need to pay more attention to the implications of less for a market economy and the effects upon people under our present economic configuration

moving back home insurance against labor market risk this paper demonstrates that the option to move in and out of the parental home is a valuable insurance channel against labor market risk which facilitates the pursuit of jobs with the potential for high earnings growth using monthly panel data i document an empirical relationship among coresidence individual labor market events and subsequent earnings growth i estimate the parameters of a dynamic game between youths and parents to show that the option to live at home can account for features of aggregate data for low skilled young workers small consumption responses to shocks high labor elasticities and low savings rates

estimating bilateral exposures in the german interbank market is there a danger of contagion abstract credit risk associated with interbank lending may lead to domino effects where the failure of one bank results in the failure of other banks not directly affected by the initial shock recent work in economic theory shows that this risk of contagion depends on the precise pattern of interbank linkages we use balance sheet information to estimate a matrix of bilateral credit relationships for the german banking system and test whether the breakdown of a single bank can lead to contagion we find that in the absence of a safety net there is considerable scope for contagion that could affect a large proportion of the banking system the financial safety net in this case institutional guarantees for saving banks and cooperative banks considerably reduces but does not eliminate the danger of contagion even so the failure of a single bank could lead to the breakdown of up to 15 of the banking system in terms of assets

inter vivos transfers and intended bequests abstract empirical work on intergenerational transfers has focused on distinguishing between altruistic and exchange motivated behavior however these two models are unable to explain the strong tendency for inter vivos transfers to be negatively related to the income of the recipient while bequests bear no relationship to income this paper presents a new framework for analyzing transfers from parents to children that is more consistent with observed behavior than are the altruistic and exchange models alone in particular the model developed here predicts differing behavior with respect to inter vivos transfers and bequests due to liquidity constraints and uncertainty about the recipient s permanent income the empirical work uses data from the health and retirement study and the asset and health dynamics study the patterns observed in these data are consistent with earlier findings that inter vivos transfers go disproportionately to less well off children while bequests are divided equally across children further the results support the predictions of the model in that differences in inter vivos transfers arise from differences in current income while differences in bequests result when indicators of the children s permanent incomes differ

rational herding in financial economics abstract this paper briefly describes recent papers on the economics of rational herding in financial markets some models can predict perfect herding in which rational agents all act alike without any countervailing force such herding typically arises either from direct payoff externalities negative externalities in bank runs positive externalities in the generation of trading liquidity or in information acquisition principal agent problems based on managerial desire to protect or signal reputation or informational learning cascades the paper also provides a few pointers to related literature and suggests issues to be addressed in future research

household consumption smoothing through ethnic ties evidence from cote d ivoire abstract this paper investigates the hypothesis that households in cote d ivoire take part in spatially diversified risk sharing arrangements with members of their own ethnic group empirical tests are presented using several estimation methods to deal with heteroscedasticity measurement error and extreme value problems to examine whether results are robust across estimation procedures the hypothesis of complete risk sharing within ethnic groups is rejected however there appears to be some partial insurance performed by individual households with other members of the same ethnic group particularly for the households residing in the regions least likely to have access to formal financial arrangements

bank runs as an equilibrium phenomenon a standard demand deposit contract in which individuals are entitled to their full deposit at any time provided the bank is solvent is analyzed in a context in which there are no exogenous events on which agents condition their behavior and a unique equilibrium involving a bank run with positive probability is shown to exist

overcoming accumulation is a capitalist steady state economy possible abstract this article critically reviews the case for a steady state zero growth economy posing the question whether such an economy can be stable and socially just given that in the current global economy lack of growth is synonymous with crisis the sse thesis is analysed within a framework of marxian political economy concluding that a stable and just sse is possible but not feasible within the social relations of capitalism using the marxian analysis of capital accumulation the article then considers whether the reforms proposed by ecological economists can form an effective countervailing force to the drive for accumulation the conclusion is that such reforms can be successful but only in so far as they are complemented and brought to their logical conclusion by a wider attempt to transcend the capitalist relations of production

the saving of the elderly in micro and macro data examination of household micro data on the elderly has generally concluded that they do not dissave significantly whereas estimates using aggregate macro data have shown that the presence of a large elderly population leads to a lower saving rate this paper shows that if interactions between generations are important one would not expect these estimates to be the same the paper presents new evidence that bequests are plausibly the source of this discrepancy examination of data from young households that have received or expect bequests confirms that bequests are indeed an important factor determining the saving of the young

optimal financial crises empirical evidence suggests that banking panics are related to the business cycle and are not simply the result of sunspots panics occur when depositors perceive that the returns on bank assets are going to be unusually low we develop a simple model of this in this setting bank runs can be first best efficient they allow efficient risk sharing between early and late withdrawing depositors and they allow banks to hold efficient portfolios however if costly runs or markets for risky assets are introduced central bank intervention of the right kind can lead to a pareto improvement in welfare from the earliest times banks have been plagued by the problem of bank runs in which many or all of the bank s depositors attempt to withdraw their funds simultaneously because banks issue liquid liabilities in the form of deposit contracts but invest in illiquid assets in the form of loans they are vulnerable to runs that can lead to closure and liquidation a financial crisis or banking panic occurs when depositors at many or all of the banks in a region or a country attempt to withdraw their funds simultaneously prior to the twentieth century banking panics occurred frequently in europe and the united states panics were generally regarded as a bad thing and the development of central banks to eliminate panics and ensure financial stability has been an important feature of the history of financial systems it has been a long and involved process the first cerntral bank the bank of sweden was established more than 300 years ago the bank of england played an especially important role in the development of effective stabilization policies in the eighteenth and nineteenth centuries by the end of the nineteenth century banking panics had been eliminated in europe the last true panic in england was the overend gurney company crisis of 1866

bank run psychology abstract banks are inherently susceptible to panics and bank runs due to the problem of maturity mismatch resulting in both a stable equilibrium in which the bank survives and an unstable equilibrium in which a bank run occurs understanding equilibrium selection in this setting is extremely important for safeguarding financial stability in this paper one new potential factor that determines whether a bank runs gets triggered or not is experimentally studied namely the psychological state of the depositor prior to participating in an experimental bank run game subjects are either induced with fear sadness or happiness using an autobiographical emotion induction task the findings suggest that the presence of background fear significantly increases the likelihood of withdrawal and a subsequent bank run in addition women are shown to be significantly more likely to withdraw then men but only in the fear induction treatment

the economics of degrowth economic degrowth is ecologically desirable and possibly inevitable but under what conditions can it become socially sustainable how can we have full employment and economic stability without growth what will happen to public spending and to public debt how would production be organised in a degrowing economy and under what plausible socio political conditions could such grand changes happen standard economic theories and models ignore these questions for them economic growth is an axiomatic necessity this article reviews recent contributions in the economics of degrowth and identifies research avenues for ecological economists

in defence of degrowth abstract this article defends the proposal of sustainable degrowth a starting premise is that resource and co2 limits render further growth of the economy unsustainable if degrowth is inevitable the question is how it can become socially sustainable i e a prosperous and stable rather than a catastrophic descent pricing mechanisms alone are unlikely to secure smooth adaptation a full ensemble of environmental and redistributive policies is required including among others policies for a basic income reduction of working hours environmental and consumption taxes and controls on advertising policies like these that threaten to harm the economy are less and less likely to be implemented within existing market economies whose basic institutions financial property political and redistributive depend on and mandate continuous economic growth an intertwined cultural and political change is needed that will embrace degrowth as a positive social development and reform those institutions that make growth an imperative sustainable degrowth is therefore not just a structuring concept it is a radical political project that offers a new story and a rallying slogan for a social coalition built around the aspiration to construct a society that lives better with less

risk sharing between and within families this paper uses the panel study of income dynamics to test whether risk sharing is complete between or within american families the tests accommodate a wide variety in the configuration and availability of family data the test results reject inter as well as intra family full risk sharing even assuming that leisure is endogenous or that leisure and consumption are nonseparable

deposit competition and financial fragility evidence from the us banking sector preliminary and incomplete please do not cite without permission we develop and estimate an empirical model of the u s banking sector using a new data set covering the largest u s banks over the period 2002 2013 our model incorporates insured depositors and run prone uninsured depositors who have rich preferences over dierentiated banks banks compete for deposits in the spirit of matutes and vives 1996 and can endogenously default we estimate demand for uninsured

contagious bank failures in a free banking system this paper develops a model of an unregulated banking system based around a private clearing house arrangement whilst such a system may dominate one with a public safety net in reducing moral hazard in lending and therefore the scope for individual bank insolvency it also increases the likelihood of contagious bank failures following a systemic shock or an aggregate liquidity shortage

motives for private transfers over the life cycle an analytical framework and evidence for peru abstract this paper tests for the motives for private income transfers we consider two motives altruism and exchange the question of private transfer motives is important because such motivation can influence the effects of public income transfers on the distribution of income using a household survey for peru we find that transfer amounts received increase with recipient pre transfer income which contradicts a key prediction of the strong form of the altruism hypothesis but is consistent with exchange we also find that capital market imperfections are likely to be an important cause of private transfers and that social security benefits crowd out the incidence of private transfers

bequests as signals an explanation for the equal division puzzle in the united states more than two thirds of decedents with multichild families divide their estates exactly equally among their children in contrast gifts given before death are usually unequal these findings challenge the validity of existing theories regarding the determination of intergenerational transfers in this paper we develop a theory that accounts for this puzzle based on the notion that the division of bequests provides a signal about a parent s altruistic preferences the theory can also explain the norm of unigeniture which prevails in other societies

the role of intergenerational transfers in aggregate capital accumulation this paper uses historical u s data to directly estimate the contribution of intergenerational transfers to aggregate capital accumulation the evidence presented indicates that intergenerational transfers account for the vast majority of aggregate u s capital formation only a negligible fraction of actual capital accumulation can be traced to life cycle or hump savings a major difference between this study and previous investigations of this issue is the use of more accurate longitudinal age earnings and age consumption profiles these profiles are simply too flat to generate substantial life cycle savings this paper suggests the importance of and need for substantially greater research and data collection on intergenerational transfers life cycle models of savings that emphasize savings for retirement as the dominant form of capital accumulation should give way to models that illuminate the determinants of intergenerational transfers

risk sharing within families evidence from the health and retirement study abstract we report strong empirical support for the presence of self interest based risk sharing within extended families in the u s a standard model of self interest based risk sharing predicts that the share of current family income consumed by a child positively depends on that child s permanent income it follows that parental transfers to children that are expected to earn more over the period of risk sharing arrangements should exhibit less sensitivity to the recipient s income fluctuations we test this distinguishing prediction of self interest based risk sharing by exploiting the variation of transfer receipts among siblings observed over 17 years of longitudinal data spanned by the health and retirement study

the prerequisites for a degrowth paradigm shift insights from critical political economy abstract what would it take for a degrowth paradigm shift to take place drawing on contemporary critical political economy scholarship this article identifies four prerequisites for socio economic paradigm shifts deep crisis an alternative political project a comprehensive coalition of social forces promoting the project in political struggles and broad based consent it is argued that on the one hand there is much to suggest that current crises cannot be resolved under existing institutional frameworks and that degrowth is a political project that provides solutions to some of the key problems currently facing humanity on the other hand the prospects for a degrowth paradigm shift remain bleak unlike political projects that became hegemonic in the past degrowth has neither support from a comprehensive coalition of social forces nor any consent to its agenda among the broader population

outside and inside liquidity we propose an origination and contingent distribution model of banking in which liquidity demand by short term investors can be met with cash reserves inside liquidity or sales of assets outside liquidity to long term investors outside liquidity is a more e cient source but asymmetric information about asset quality can introduce a friction in the form of excessively early asset trading in anticipation of a liquidity shock excessively high cash reserves and too little origination of assets by banks the model captures elements of the current flnancial crisis and yields policy prescriptions on public liquidity provision to overcome liquidity crises

full insurance in the presence of aggregate uncertainty this paper tests implications of full consumption insurance the object is to determine how much mileage can be obtained from a model with complete markets with such features as private information or liquidity constraints omitted the implication exploited is that individual consumption responds to aggregate risk but not to idiosyncratic risk the test involves regressing the change in household consumption onto the change in aggregate consumption and other right hand side variables such as the change in household income and change in employment status all variables other than the change in aggregate consumption are predicted to be insignificant in explaining the change in household consumption with observations on consumption and income for 10 695 households from the consumer expenditure survey the results are mixed the results for one specification exponential utility are mostly consistent with full consumption insurance the results for the other specification power utility are not

liquidity coinsurance moral hazard and financial contagion we study the propagation of financial crises between regions characterized by moral hazard problems the source of the problem is that banks are protected by limited liability and may engage in excessive risk taking the regions are affected by negatively correlated liquidity shocks so that liquidity coinsurance is pareto improving the moral hazard problem can be solved if banks are sufficiently capitalized under autarky a limited investment is needed to achieve optimality so that a limited amount of capital is sufficient to prevent risk taking with interbank deposits the optimal investment increases and capital becomes insufficient to prevent excessive risk taking thus bankruptcy occurs with positive probability and the crises spread to other regions via the financial linkages opening the financial markets is nevertheless pareto improving consumers benefit from liquidity coinsurance although they pay the cost of excessive risk taking finally we show that in this framework a completely connected deposit structure is more conducive to financial crises than an incompletely connected structure

a simple test of consumption insurance are consumers effectively insured against idiosyncratic shocks to income or wealth either by formal institutions such as charities private insurance and government programs or by informal mechanisms such as gifts and loans from relatives friends and neighbors under full insurance consumption growth should be cross sectionally independent of idiosyncratic variables that are exogenous to consumers this proposition is tested by cross sectional regressions of consumption growth on a variety of exogenous variables full insurance is rejected for long illness and involuntary job loss but not for spells of unemployment loss of work due to strike and an involuntary move

motives for private income transfers private income transfers are becoming increasingly recognized as a key aspect of the u s economy the majority of private income transfers occur inter vivos i e between living persons but very little is known about this type of transfer behavior this paper tests alternative hypotheses concerning motivation for inter vivos transfers two motives are considered altruism and exchange evidence presented here casts doubt on the altruistic model of transfer behavior observed patterns for inter vivos transfers are more consistent with exchange related motives this finding has important implications for the effects of public transfer programs on the distribution of economic well being

heterogeneity and stability bolster the strong not the weak we first study a stylized model of self fulfilling panic among agents with differing fragilities to strategic risk and show that depending on the severity of coordination problems the panic trigger threshold can depend only on one type s fragility we then present a model of systemic panic among financial institutions with heterogeneous fragilities to financial spillovers concerns about potential spillovers generate strategic interaction triggering a pre emption game in which one tries to exit the market before others to avoid spillovers although financial contagion originates in weaker institutions systemic risk can critically depend on financial health of stronger in the contagion chain in this case bolstering the strong rather than the weak more effectively enhances systemic stability

building an incentive compatible safety net abstract bank safety nets originally proposed as a means of stabilizing financial systems have become an important destabilizing influence government protection of bank debts encourages banks to undertake excessive risk particularly in response to adverse shocks to asset values reforms that would remove the destabilizing moral hazard consequences of government protection are considered both from the perspective of economic desirability and political feasibility requiring banks to maintain a minimal proportion of subordinated debt finance and restricting the means by which government recapitalization of insolvent banks occurs are the central features of promising reforms to the safety net

parental altruism and inter vivos transfers theory and evidence this paper uses psid data on the extended family to test whether inter vivos transfers from parents to children are motivated by altruism specifically the paper tests whether an increase by one dollar in the income of parents actively making transfers to a child coupled with a one dollar reduction in that child s income results in the parents increasing their transfer to the child by one dollar this restriction on parental and child transfer income derivatives is derived for the standard altruism model augmented to include uncertainty and liquidity constraints these additional elements pin down the timing of inter vivos transfers the method used to estimate income transfer derivatives takes into account unobserved heterogeneity across families in the degree of altruism the findings strongly reject the altruism hypothesis redistributing one dollar from a recipient child to donor parents leads to less than a 13 cent increase in the parents transfer to the child far less than the one dollar increas

social enterprises and non market capitals a path to degrowth the aim of this paper is to look at alternatives to the classic for profit shareholding enterprise and to suggest how such alternatives might be supported within the current economic system another aim is to link the social enterprise and degrowth discourses we first re define the economy as including non monetised sectors the core economy and the economy of nature and discuss the liminal zone of not for profit and not only for profit organisations we then look at social enterprise definitions from a degrowth perspective and explain why the dimensions of scale place environment and provisioning patterns need more space in the social enterprise discourse after that we define non market capitals as capitals taken out of the market and placed under local member democratic control and explain their importance in a degrowth economy we give examples of non market capitals and suggest a model involving mutual support between primary and secondary social enterprises finally we suggest areas where more research is needed in this emerging field of inquiry

bank failure contagion in historical perspective abstract bank failures are contagious due to the lack of bank specific information depositors who lack financial information on individual banks make withdrawal decisions based on the condition of the banking system as a whole a high ratio of bank failures then signals an adverse condition within the banking sector and triggers systemwide bank runs this paper looks at bank panics in u s history and shows the importance of solvency information specific to individual banks the major empirical finding is that the government or banks stopped bank panics mainly by providing financial information on banks

the lender of last resort abstract this paper develops a model of the lender of last resort lolr from a central bank cb viewpoint the model in a static setting suggests that the cb would only rescue banks which are above a threshold size consistent with the insight of too big to fail in a dynamic setting cb s optimal policy in liquidity support depends on the trade off between contagion and moral hazard effects our results show that contagion is the key factor affecting cb s incentives in providing lolr and they also provide a rationalization for constructive ambiguity

on the international harmonization of bank regulation this paper offers a three way typology of bank regulation and examines the question of international harmonization for each category for economic regulation the danger is that harmonization could support and preserve domestic protectionist regulatory regimes but it could instead be a beneficial guise for lowering protectionist barriers the latter efforts should be encouraged for prudential regulation national regulation should be adequate to handle the extra stresses of international banking harmonization efforts e g the basle accord may offer only modest help but the accord may offer indirect help by limiting national governments competitive efforts implicitly to subsidize their banks risk taking activities finally for information regulation national regulation appears to be adequate and international harmonization does not appear to be necessary copyright 1994 by oxford university press

bailouts and financial fragility how does the belief that policymakers will bail out investors in the event of a crisis affect the allocation of resources and the stability of the financial system i study this question in a model of financial intermediation with limited commitment when a crisis occurs the efficient policy response is to use public resources to augment the private consumption of those investors facing losses the anticipation of such a bailout distorts ex ante incentives leading intermediaries to choose arrangements with excessive illiquidity and thereby increasing financial fragility prohibiting bailouts is not necessarily desirable however it induces intermediaries to become too liquid from a social point of view and may in addition leave the economy more susceptible to a crisis a policy of taxing short term liabilities in contrast can correct the incentive problem while improving financial stability

intergenerational transfers and the accumulation of wealth h t ouseholds acquire wealth from two sources they save out of income they have earned and they receive transfers from other people the first method of wealth accumulation goes under the name of life cycle saving in which people save during their working lives and dissave after retirement the second involves either an inter vivos transfer that is a transfer between living people or a bequest a transfer that occurs at the death of the donor while inter vivos transfers and bequests will arise in dynastic models where preferences include a taste for the well being of one s descendents few empirical life cycle models reflect these concerns indeed a sharp debate has arisen over the ability of the simple life cycle model to explain observed wealth accumulation understanding the relative sizes of these sources of wealth accumulation affects a variety of issues for example the effects of government debt social insurance public transfer programs estate taxes and incentives for charitable giving depend to some extent on the magnitude and nature of private saving and transfers of wealth analyses of the inequality of wealth may depend on whether most of wealth is earned or received as transfers appropriate policies for encouraging private saving may look rather different depending on whether most saving is to be consumed later in life or passed along to the next generation finally evidence on transfer patterns relates to more fundamental

debt constrained asset markets we develop a theory of general equilibrium with endogenous debt limits in the form of individual rationality constraints similar to those in the dynamic consistency literature if an agent defaults on a contract he can be excluded from future contingent claims markets trading and can have his assets seized he cannot be excluded from spot markets trading however and he has some private endowments that cannot be seized all information is publicly held and common knowledge and there is a complete set of contingent claims markets since there is complete information an agent cannot enter into a contract in which he would have an incentive to default in some state in general there is only partial insurance variations in consumption may be imperfectly correlated across agents interest rates may be lower than they would be without constraints and equilibria may be pareto ranked

interbank contagion at work evidence from a natural experiment this article tests financial contagion due to interbank linkages for identification we exploit an idiosyncratic sudden shock caused by a large bank failure in conjunction with detailed data on interbank exposures first we find robust evidence that higher interbank exposure to the failed bank leads to large deposit withdrawals second the magnitude of contagion is higher for banks with weaker fundamentals third interbank linkages among surviving banks further propagate the shock finally we find results suggesting that there are real economic effects these results suggest that interbank linkages act as an important channel of contagion and hold important policy implications jel g01 g21 g28 e58 since the onset of the financial turmoil increased uncertainty reflected particularly in counterparty risk has led banks to hoard liquidity this has resulted in a significant decline of trading in the interbank money markets jean claude trichet president of the european central bank december 2008

imperfect commitment altruism and the family evidence from transfer behavior in low income rural areas in this paper we examine empirically whether risk pooling is more advantageous among altruistic compared to selfish agents in a framework where individuals cannot make binding commitments in particular we incorporate altuism into a model of risk sharing under imperfect commitment and use simulation methods to establish tests of the roles of both altruism and commitment problems in determining the extent of insurance and the intertemporal movements in interhousehold transfers the tests are carried out using three panel data sets from two countries of rural south asia that provide detailed information on transfers and enable the measurement of income shocks the estimates provide strong support for the notion that imperfect commitment substantially constrains informal transfer arrangements whether kin based or not but also provide evidence that altruism plays an important role in ameliorating commitment constraints and thus in increasing the gains from income pooling

is the extended family altruistically linked direct tests using micro data this paper uses panel study of income dynamics data on parents and their adult children to test the standard altruism model this model predicts that within the extended family the distribution of consumption is independent of the distribution of resources the authors findings strongly reject this prediction copyright 1992 by american economic association
