crisis or opportunity economic degrowth for social equity and ecological sustainability introduction to this special issue abstract this article reviews the burgeoning emerging literature on sustainable degrowth this is defined as an equitable downscaling of production and consumption that increases human well being and enhances ecological conditions at the local and global level in the short and long term the paradigmatic propositions of degrowth are that economic growth is not sustainable and that human progress without economic growth is possible degrowth proponents come from diverse origins some are critics of market globalization new technologies or the imposition of western models of development in the rest of the world all criticize gdp accounting though they propose often different social and ecological indicators degrowth theorists and practitioners support an extension of human relations instead of market relations demand a deepening of democracy defend ecosystems and propose a more equal distribution of wealth we distinguish between depression i e unplanned degrowth within a growth regime and sustainable degrowth a voluntary smooth and equitable transition to a regime of lower production and consumption the question we ask is how positive would degrowth be if instead of being imposed by an economic crisis it would actually be a democratic collective decision a project with the ambition of getting closer to ecological sustainability and socio environmental justice worldwide most articles in this issue were originally presented at the april 2008 conference in paris on economic degrowth for ecological sustainability and social equity this conference brought the word degrowth and the concepts around it into an international academic setting articles of this special issue are summarized in this introductory article hueting d alessandro and colleagues van den bergh kerschner spangenberg and alcott discuss whether current growth patterns are un sustainable and offer different perspectives on what degrowth might mean and whether and under what conditions it might be desirable matthey and hamilton focus on social dynamics and the obstacles and opportunities for voluntary social action towards degrowth lietaert and cattaneo with gavalda offer a down to earth empirical discussion of two practical living experiments cohousing and squats highlighting the obstacles for scaling up such alternatives finally van griethuysen explains why growth is an imperative in modern market economies raising also the question whether degrowth is possible without radical institutional changes

digital contracts simple tools for pricing complex derivatives this article presents a simple unified approach for valuing a variety of financial assets using digital contracts three types of digitals are used a digital option paying either one dollar or nothing a digital share paying nothing or converting into one share of the underlying asset and a first touch digital paying one dollar the first time that the price of the underlying stock moves into some specified region it is shown how the values of these three types of digitals can be determined for a wide variety of payoff events and how they can be combined to price complex contracts copyright 2000 by university of chicago press

electoral outcomes with probabilistic voting and nash social welfare maxima abstract this paper provides unexpected support to nash s view of how bargaining determines the social choice we first present a spatial model of electoral competition with probabilistic voting and a very close relation between voters preferences and their choice probabilities the outcome of the electoral competition game is then shown to be precisely the social alternative that maximizes a nash type social welfare function theorem 1 this electoral outcome is also interpreted as a unanimity likelihood maximum corollary 1 within our framework existence and uniqueness of such an outcome are guaranteed corollaries 2 and 3

global diversification growth and welfare with imperfectly integrated markets for goods in this article we examine the effect of the imperfect mobility of goods on international risk sharing and through that on the investment in risky projects welfare and growth our main result is that the welfare gain from integration of financial markets is not greatly reduced by the presence of goods market imperfections modeled as a cost of transferring goods from one country to the other we also find that the gain is nonmonotonic with respect to investors risk aversion and the aggregate volatility of output growth the policy implication to be drawn is that financial market integration is a worthwhile goal to pursue even when full goods mobility has not been achieved article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

risk taking global diversification and growth this paper develops a continuous time stochastic model in which international risk sharing can yield substantial welfare gains through its effect on expected consumption growth the mechanism linking global diversification to growth is an attendant world portfolio shift from safe low yield capital to riskier high yield capital the presence of these two types of capital captures the idea that growth depends on the availability of an ever increasing array of specialized hence inherently risky production inputs calibration exercises using consumption and stock market data imply that most countries reap large steady state welfare gains from global financial integration copyright 1994 by american economic association

least cost 100 renewable electricity scenarios in the australian national electricity market least cost options are presented for supplying the australian national electricity market nem with 100 renewable electricity using wind photovoltaics concentrating solar thermal cst with storage hydroelectricity and biofuelled gas turbines we use a genetic algorithm and an existing simulation tool to identify the lowest cost investment and operating scenarios of renewable technologies and locations for nem regional hourly demand and observed weather in 2010 using projected technology costs for 2030 these scenarios maintain the nem reliability standard limit hydroelectricity generation to available rainfall and limit bioenergy consumption the lowest cost scenarios are dominated by wind power with smaller contributions from photovoltaics and dispatchable generation cst hydro and gas turbines the annual cost of a simplied transmission network to balance supply and demand across nem regions is a small proportion of the annual cost of the generating system annual costs are compared with a scenario where fossil fuelled power stations in the nem today are replaced with modern fossil substitutes at projected 2030 costs and a carbon price is paid on all emissions at moderate carbon prices which appear required to address climate change 100 renewable electricity would be cheaper on an annual basis than the replacement scenario

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

a model of credit risk optimal policies and asset prices this article studies an economy with borrowers firms or individuals under costly default borrowers defaulting under adverse economic conditions may despite incurring default costs emerge as wealthier than nonborrowers asset substitution is generally not pronounced although a larger risk exposure by borrowers may also occur and then binary options emerge as useful credit derivatives the asset value dynamics are endogenously determined and shown to exhibit stochastic mean and volatility in contrast to many credit risk models in equilibrium the market level is increased decreased in economic downturns upturns by the presence of credit risk

degrowth from theory to practice abstract the collection of articles reviewed in this editorial presents an eclectic sample of the best contributions from the second international conference on degrowth exemplifying recent debates in the field and touching on different aspects of the multi dimensional transition at stake moving beyond theory and the construction of the degrowth proposal the articles in this special issue look at particular applications new methodologies and fresh policy options for example social enterprises are evaluated as primer candidates for a sustainable degrowth economy in the north lessons are also drawn from very different parts of the world such as cuba s experience with an oil and commodity shock to which it adapted through the introduction of ecological labour intensive agriculture in urban regions this special issue approaches from a degrowth perspective important sectoral issues in agriculture resource consumption and water the unsustainable fuel dependence of the spanish agrarian sector where the energy input for the production process is six times higher than the energy contained in finished food products is analysed in the context of the industrialization of food production rather than efficiency sufficiency in consumption is proposed as an organising societal principle and a call is made for stronger ngo action and coalition building in the direction of absolute rather than relative consumption reduction the obstacles to sufficiency policies are illustrated with a case study on water in the city of barcelona where a growth discourse is still dominant and a source of a technological and institutional deadlock against softer decentralized and more participatory forms of water management finally many of the contributions in this issue focus on work the policy option of a job guarantee scheme is examined as a tool to decouple jobs from economic growth and fiscal policy by bringing them to the realm of political rights this is complemented by a discussion of the social benefits of an amateur economy through work sharing and a socially beneficial reduction in labour productivity original data from barcelona analysed for this special issue shows that household activities an essential component of a more amateur economy have a much lower intensity of energy use than the paid sector delivery of equivalent services especially government and privatized caring services interesting research questions are identified concerning work under a degrowth trajectory not least whether reducing paid work will be possible in an energy scarce future put together the diverse contributions of this issue show that there is a vibrant and fertile degrowth research agenda with a range of open questions to which the community of this journal has much to offer

measuring progress in the degrowth transition to a steady state economy article i nfo in order to determine whether degrowth is occurring or how close national economies are to the concept of a steady state economy clear indicators are required within this paper i analyse four indicator approaches that could be used 1 gross domestic product 2 the index of sustainable economic welfare 3 biophysical and social indicators and 4 a composite indicator i conclude that separate biophysical and social indicators represent the best approach but a unifying conceptual framework is required to choose appropriate indicators and interpret the relationships between them i propose a framework based on ends and means and a set of biophysical and social indicators within this framework the biophysical indicators are derived from herman daly s definition of a steady state economy and measure the major stocks and flows in the economy environment system the social indicators are based on the stated goals of the degrowth

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

a positive theory of the earnings relationship of unemployment benefits in a wage bargaining model a stronger earnings relationship of unemployment benefits may reduce wages therefore the benefit structure significantly influences profits and trade union utility raising the question as to how the benefit structure is determined in the political process we consider a government that chooses the earnings relationship in order to maximize its political support our model predicts a strong earnings relationship under right wing governments and a weak relationship when unions are influential using panel data for 19 oecd countries we find support for these theoretical predictions moreover we show that the earnings relationship varies negatively with openness

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

continuous time methods in finance a review and an assessment i survey and assess the development of continuous time methods in finance during the last 30 years the subperiod 1969 to 1980 saw a dizzying pace of development with seminal ideas in derivatives securities pricing term structure theory asset pricing and optimal consumption and portfolio choices during the period 1981 to 1999 the theory has been extended and modified to better explain empirical regularities in various subfields of finance this latter subperiod has seen significant progress in econometric theory computational and estimation methods to test and implement continuous time models capital market frictions and bargaining issues are being increasingly incorporated in continuous time theory the roots of modern continuous time methods in finance can be traced back to the seminal contributions of merton 1969 1971 1973b in the late 1960s and early 1970s merton 1969 pioneered the use of continuous time modeling in financial economics by formulating the intertemporal consumption and portfolio choice problem of an investor in a stochastic dynamic programming setting merton 1973b also showed how such a framework can be used to develop equilibrium asset pricing implications thereby significantly extending the asset pricing theory to richer dynamic settings and expanding the scope of applications of continuous time methods to study problems in financial economics 1 within a span of about 30 years from the publication of merton s inf luential papers continuous time methods have become an integral part of financial economics indeed in certain core areas in finance such as e g asset pricing derivatives valuation term structure theory and portfolio selection continuoustime methods have proved to be the most attractive way to conduct research and gain economic intuition the continuous time approach in these areas has produced models with a rich variety of testable implications the econometric theory for testing continuous time models has made rapid strides in the last decade and has thus kept pace with the impressive progress on the theoretical front one hopes that the actual empirical investigations and estimation using the new procedures will follow suit soon

an intertemporal general equilibrium model of asset prices this paper develops a continuous time general equilibrium model of a simple but complete economy and uses it to examine the behavior of asset prices in this model asset prices and their stochastic properties are determined endogenously one principal result is a partial differential equation which asset prices must satisfy the solution of this equation gives the equilibrium price of any asset in terms of the underlying real variables in the economy in this paper we develop a general equilibrium asset pricing model for use in applied research an important feature of the model is its integration of real and financial markets among other things the model endogenously determines the stochastic process followed by the equilibrium price of any financial asset and shows how this process depends on the underlying real variables the model is fully consistent with rational expectations and maximizing behavior on the part of all agents our framework is general enough to include many of the fundamental forces affecting asset markets yet it is tractable enough to be specialized easily to produce specific testable results furthermore the model can be extended in a number of straightforward ways consequently it is well suited to a wide variety of applications for example in a companion paper cox ingersoll and ross 7 we use the model to develop a theory of the term structure of interest rates many studies have been concerned with various aspects of asset pricing under uncertainty the most relevant to our work are the important papers on intertemporal asset pricing by merton 19 and lucas 16 working in a continuous time framework merton derives a relationship among the equilibrium expected rates of return on assets he shows that when investment opportunities are changing randomly over time this relationship will include effects which have no analogue in a static one period model lucas considers an economy with homogeneous individuals and a single consumption good which is produced by a number of processes the random output of these processes is exogenously determined and perishable assets are defined as claims to all or a part of the output of a process and the equilibrium determines the asset prices our theory draws on some elements of both of these papers like merton we formulate our model in continuous time and make full use of the analytical tractability that this affords the economic structure of our model is somewhat similar to that of lucas however we include both endogenous production and

local currencies for purposive degrowth a quality check of some proposals for changing money as usual this article provides a quality check of the degrowth movement s proposal of local currencies as tools for advancing socially equitable and ecologically sustainable degrowth the article draws comprehensively upon mainly english language academic research about four widespread local currency types lets time banks hour currencies and convertible local currencies clcs to assess their performance with respect to four degrowth related criteria community building advancement of alternative values in economic exchange facilitation of alternative livelihoods and eco localization lets have been found to support alternative livelihoods under quite uncommon conditions and contribute indirectly to eco localization by moderately facilitating informal resale repair and sharing of commercially produced goods although their burdensome management and confinement to small memberships limit their usefulness time banks help expand social networks and are best at reaching the socially excluded however they are confined to unskilled personal services and dependent on grant funding hour currencies do not stand out with regard to any criteria but may have a minor capacity to promote local purchasing clcs are best at attracting local businesses but no significant evidence of their said capacity to localize supply chains has surfaced as yet and their business friendly design works to the detriment of other criteria in sum existing research provides a very weak basis for advocating local currencies as tools for purposive degrowth local currencies are here categorized as two utopian socialist approaches the behind society s back variety of lets and hour currencies and the appeal to elites variety of time banks and clcs marx and engels s critiques of these approaches remain valid successful monetary systems require resources that are not available behind society s back notably the power to levy taxes and designate by which means they can be paid local currencies that appeal for elite support without mass popular backing have shaken off most radical connotations and are vulnerable to changing policy agendas given the present historical conjuncture of popular outrage against the banking sector this paper argues that the degrowth movement would improve its chances of contributing to purposive degrowth by prioritizing government centred ecological reform of the monetary system over local currencies

can renewables meet total australian energy demand a disaggregated approach abstract attempts to assess the possibility of deriving all energy from renewable sources typically deal only with the aggregate amount of energy required and do not consider the implications and difficulties arising from the need for differing forms of energy in a 100 renewable system some of these forms will have to be provided by conversion from others mostly from electricity conversion involves inefficiencies losses and embedded energy costs of infrastructures and thus energy and dollar costs in this study an attempt has been made to determine the magnitude and effect of this general problem by beginning with estimates of the quantities required by different sectors and of the different forms they use how these needs might best be met in a renewable system is then considered although there is insufficient data to enable confident conclusions this disaggregated approach indicates that a 100 renewable system to meet australian energy demand would involve costs that would probably constitute an unacceptably large fraction of gdp

balanced budget redistribution as the outcome of political competition this paper models balanced budget redistribution between socio economic groups as the outcome of electoral competition between two political parties equilibrium is unique in the present model and a sufficient condition for existence is given requiring that there be enough stochastic heterogeneity with respect to party preferences in the electorate the validity of hotelling s principle of minimum differentiation and of director s law are examined under alternative hypotheses concerning administrative costs of redistributions and voter s possibilities both of abstaining from voting and of becoming campaign activists for one of the parties the policy strategy of expected plurality maximization is contrasted with the strategy of maximizing the probability of gaining a plurality incomes are fixed and known so lump sum taxation is feasible however constraints on tax transfer differentiation between individuals are permitted in the analysis

the equity performance of firms emerging from bankruptcy this study assesses the stock return performance of 131 firms emerging from chapter 11 using differing estimates of expected returns we consistently find evidence of large positive excess returns in 200 days of returns following emergence we also examine the reaction of our sample firms equity returns to their earnings announcements after emergence from chapter 11 the positive and significant reactions suggest that our results are driven by the market s expectational errors not mismeasurement of risk the results provide an interesting contrast but not a contradiction to previous work that has documented poor operating performance for firms emerging from chapter 11 with large corporate bankruptcies being commonplace during the late 1980s and early 1990s there has been a notable increase in the number of firms emerging from bankruptcy altman 1991 1993 when firms emerge from bankruptcy they often cancel the old stock and distribute an entirely new issue of common stock the stocks of firms emerging from a chapter 11 bankruptcy are often called orphan equities among practitioners and there have been reports in the popular press about spectacular returns in this market for example as sandler 1991 p cl states

reform support in times of crisis the role of family ties we argue that an important determinant of voters support for economic reform is the strength of family ties while the crisis hypothesis predicts that crises facilitate reform we show in a political economy model that this relation can break down and even reverse when agents take into account the effect of reform on their family members applied to southern european countries with strong family ties the model rationalizes why the extremely high youth unemployment following the great recession has not led to more substantial labor market reforms in such countries austerity might block rather than foster additional structural reforms

the nature of the firm and peculiarities of the corporation i must thank the independent social research foundation for generous funding of the research on which this paper draws

explaining welfare spending welfare expenditures are difficult to explain within a pure public choice framework in this article i shall argue that the difficulties may be resolved by assuming that the main purpose of welfare schemes is to provide the electorate in their capacity of different risk categories with insurance against various social risks rather than to redistribute economic resources towards weak and destitute groups in society this solution not only explains the scope of existing welfare arrangements but may also hold the key to an explanation as to how public welfare policies change and evolve across time

the determination of unemployment benefits while much empirical research exists on labor market consequences of unemployment benefits there is remarkably little evidence on the forces determining benefits we present a simple model where workers desire insurance against unemployment risk and benefits increase the unemployment rate we then conduct one of the first empirical analyses of the determinants of the parameters of the benefit system using data for developed countries for 1971 89 controlling for year and country fixed effects and the government s political color we find evidence that the level of benefits falls when the unemployment rate is high this is consistent with wright s tax effect

new foundations for ecological economics abstract ecological economics has been repeatedly described as transdiciplinary and open to including everything from positivism to relativism i argue for a revision and rejection of this position in favour of realism and reasoned critique looking into the ontological presuppositions and considering an epistemology appropriate for ecological economics to meaningfully exist requires rejecting the form of methodological pluralism which has been advocated since the start of this journal this means being clear about the differences in our worldview or paradigm from others and being aware of the substantive failures of orthodox economics in addressing reality this paper argues for a fundamental review of the basis upon which ecological economics has been founded and in so doing seeks improved clarity as to the competing and complementary epistemologies and methodologies in part this requires establishing serious interdisciplinary research to replace superficial transdisciplinary rhetoric the argument places the future of ecological economics firmly amongst heterodox economic schools of thought and in ideological opposition to those supporting the existing institutional structures perpetuating a false reality of the world s social environmental and economic systems and their operation

a two factor hazard rate model for pricing risky debt and the term structure of credit spreads this paper proposes a two factor hazard rate model in closed form to price risky debt the likelihood of default is captured by the firm s non interest sensitive assets and defaultfree interest rates the distinguishing features of the model are threefold first the impact of capital structure changes on credit spreads can be analyzed second the model allows stochastic interest rates to impact current asset values as well as their evolution finally the proposed model is in closed form enabling us to undertake comparative statics analysis compute parameter deltas of the model calibrate empirical credit spreads and determine hedge positions credit spreads generated by our model are consistent with empirical observations

economics in the anthropocene species extinction or steady state economics abstract at the dawn of the anthropocene continued economic growth carries the risk of irreversibly damaging the global carrying capacity using data from the international union for the conservation of nature red list of threatened species 2016 i present estimates of the expected extinction rates during the coming century for 557 regions i illustrate that these rates exceed the planetary boundary formulated by rockstrom et al 2009 virtually everywhere and increase with population density and gdp per capita likewise the percentage of threatened species increases with anthropogenic pressure i find no evidence in support of an environmental kuznets curve by doing so this paper contributes to an ongoing debate on the relevance of absolute versus relative scarcity for economic thought my findings suggest that the conservation of nature would benefit from degrowth or the transition to a global steady state economy

the approach of ecological economics this paper discusses the major tenets of ecological economics including value pluralism methodological pluralism and multi criteria policy assessment ecological economics offers viable alternatives to the theoretical foundations and policy recommendations of neoclassical welfare economics a revolution in neoclassical economics is currently taking place and the core assumptions of welfare economics are being replaced with more realistic models of consumer and firm behaviour this paper argues that these new theoretical and empirical findings are largely ignored in applied work and policy applications in environmental economics as the only heterodox school of economics focusing on the human economy both as a social system and as one imbedded in the biophysical universe and thus both holistic and scientifically based ecological economics is poised to play a leading role in recasting the scope and method of economic science

degrowth business framework implications for sustainable development abstract recent years have seen a revival in growth scepticism yet degrowth in relation to the macroeconomic level has received almost exclusive attention this resulted in a lack of literature on how post growth and specifically degrowth visions of economy could be implemented including from the perspective of firms and other organisations this paper focuses on degrowth literature and fields of knowledge which share a similar or sympathetic perspective regarding the undesirability of economic growth and desirability of living within planetary boundaries while pursuing wellbeing it then applies degrowth vision to firms and identifies potential elements of a business for a degrowth economy here referred to as a degrowth business these elements comprise a degrowth business framework the framework is centred around the following groups 1 environment 2 people and non humans and 3 deviation from profit maximisation imperative it aims to contribute to an emerging discussion on what firms should be like for a degrowth economy and society to be possible

intergenerational support and the life cycle incomes of young men and their parents human capital investments coresidence and intergenerational financial transfers this article examines the resource allocations of parents in the form of both shared residence with and financial transfers to their young adult sons based on an overlapping generations model incorporating a game between parents and adult children estimates of the determinants of such transfers are obtained from the kinship linked cohorts of the national longitudinal surveys the estimates suggest that both types of parental assistance are as important as governmental transfers in supporting young men and are responsive to the current and anticipated earnings of their offspring suggesting that young men cannot adequately smooth their consumption without parental help

optimal consumption and portfolio policies when asset prices follow a diffusion process abstract we consider a consumption portfolio problem in continuous time under uncertainty a martingale technique is employed to characterize optimal consumption portfolio policies when there exist nonnegativity constraints on consumption and on final wealth we also provide a way to compute and verify optimal policies our verification theorem for optimal policies involves a linear partial differential equation unlike the nonlinear partial differential equation of dynamic programming the relationship between our approach and dynamic programming is discussed we demonstrate our technique by explicitly computing optimal policies in a series of examples in particular we solve the optimal consumption portfolio problem for hyperbolic absolute risk aversion utility functions when the asset prices follow a geometric brownian motion the optimal policies in this case are no longer linear when nonnegativity constraints on consumption and on final wealth are included by these examples one can see that our approach is much easier than the dynamic programming approach

exploring the political economy of labour market institutions labour markets how reforms took place many economists argue that the european unemployment problem relates to large labour market rigidities this paper argues that many of those inflexibilities and the underlying institutional regulations can be understood as the outcome of political influence by incumbent employees this is because many policies that increase unemployment actually benefit these insiders an empirical investigation of the determinants of labour market institutions demonstrates that the observations are consistent with this view the findings imply 1 higher exposure of the employed to unemployment facilitates a reduction in the level of employment protection 2 unemployment benefits are lower the more employment reacts to wages 3 a higher level of unemployment and the existence of a right wing government slow down the growth rate of the minimum wage giles saint paul

does unemployment insurance displace familial assistance the objective of this study is to examine the extent to whichbenefits received from the unemployment insurance programdisplace assistance that the unemployed receive from theirextended family using data from a supplement to the panelstudy of income dynamics it is found that the unemployedreceive private support and that these private networks arefairly pervasive twenty nine percent of those receivingunemployment insurance benefits also receive cash transfersfrom their family or friends moreover it is found thatunemployment benefits displace familial support by as much as24 40 cents per dollar

a comparative study of portfolio insurance abstract this paper undertakes a comparative study of portfolio insurance under a variety of modeling strategies specifically we focus on portfolio insurers who derive utility from horizon wealth with marginal utility tending smoothly to infinity at some pre specified floor we solve for the optimal consumption portfolio wealth of these portfolio insurers and compare with constrained portfolio insurers and normal agents general equilibrium conditions are contrasted under pure exchange and production type models while the market price level is unambiguously increased under pure exchange under production the effect on market level is state dependent in both models the market volatility and risk premium are decreased by portfolio insurance the paper also investigates the possible relationship between portfolio insurance type trading strategies and market volatility

happy degrowth through more amateur economy abstract this paper outlines a simple aggregate descriptive model of what is here termed a whole economy covering all human involvement in the economy from ultimate means or ecological sacrifices to the ultimate ends of human satisfaction the model embraces not only the formal professional economy driven by money but also the parallel non paid voluntary economy here termed amateur economy driven by peoples affective motivations the input of work to the economy plays an essential role in the paper s analysis of options for reducing ecological sacrifices hence part of the paper is devoted to a brief historical overview of the role of work including turning points in the 1930s in the united states when work sharing was displaced by work creation through consumerism and in the post war economy when gdp became the dominant economic indicator the paper proposes the aim of a happy and sustainable degrowth for affluent countries implying the transfer of some activities from the professional economy to the less labor productive amateur economy this will tend to reduce overall labor productivity and hence resource throughput but increase satisfaction and happiness a key element in the analysis is combining a reduction in consumption with a reduction in production which is obtainable through lowering either working time or work productivity and turning some of the leisure time into voluntary activities economic growth is not a law of nature but the consequence of explicit political decisions taken hence growth is also open to new political decisions in recognition of physical limits to growth and the human quest for replacing economic growth with life satisfaction including increased free time

the choice of insurance in the labor market employment protection and unemployment benefits are considered the most prominent insurance devices for workers to protect themselves against the risk of unemployment it occurs that societies either choose a high level of employment protection relative to unemployment benefits or vice versa this paper explains where countries locate on this trade off it is argued that higher coverage of voters out of the labor force with intra household transfers yields a politico economic equilibrium with relatively high employment protection and relatively low unemployment benefits cross country data and survey data on voters preferences are presented that corroborate the outcomes of the model

openness country size and government abstract this paper shows that smaller countries have a larger share of public consumption in gdp and are also more open to trade these empirical observations are consistent with recent theoretical models explaining country formation and break up and may account for the observed positive empirical relationship between trade openness and government size

the massetti et al criticisms of trainer s critique of the 2014 ipcc report on renewable energy a reply by trainer abstract the criticism massetti et al 2017 make is essentially that my analysis of the 2014 ipcc report trainer 2017 is mistaken because it confuses the macroeconomic or reduction in gdp cost of mitigation which is focal in chapter 6 with the investment or capital cost which is considered in chapter 16 this claim is stated but no space is given to showing what the confusion is supposed to be or to explaining how it invalidates my analysis the following brief notes make clear that these two issues were not confused in my analysis and that the comments from massetti et al do not cast doubt on my critique of the ipcc report

pricing derivatives on financial securities subject to credit risk this article provides a new methodology for pricing and hedging derivative securities involving credit risk two types of credit risks are considered the first is where the asset underlying the derivative security may default the second is where the writer of the derivative security may default we apply the foreign currency analogy of jarrow and turnbull 1991 to decompose the dollar payoff from a risky security into a certain payoff and a spot exchange rate arbitrage free valuation techniques are then employed this methodology can be applied to corporate debt and over the counter derivatives such as swaps and caps the purpose of this article is to provide a new theory for pricing and hedging derivative securities involving credit risk two sources of credit risk are identified and analyzed the first is where the asset underlying the derivative security may default paying off less than promised this is the case for example with imbedded options on corporate debt the second is the credit risk introduced by the writer of the derivative security who may also default examples include over the counter writers of options on eurodollar futures swaps and swaptions for pricing derivative securities involving credit risk there are currently two approaches the first views these derivatives as contingent claims not on the financial securities themselves but as compound options on the assets underlying the financial securities this is the case for example with the pricing of imbedded options on corporate debt see merton 1974 1977 black and cox 1976 ho and singer 1982 chance 1990 and kim ramaswamy and sundaresan 1993 or the pricing of vulnerable options see johnson and stulz 1987 in practice however this valuation methodology is difficult to use first the assets underlying the financial security are often not tradeable and therefore their values are not observable this makes application of the theory and estimation of the relevant parameters problematic second as in the case of corporate debt all of the other liabilities of the firm senior to the corporate debt must first and simultaneously be valued this generates significant computational difficulties as a result this approach has not

the ultrasocial origin of the anthropocene abstract the current geological epoch has been dubbed the anthropocene the age of humans we argue that the roots of the anthropocene lie in the agricultural revolution that began some 8000 years ago unique human psychological and cultural characteristics were present in our distant hunter gatherer past but in terms of the biophysical impact of our species agricultural represented an unequivocal and decisive evolutionary break with the transition to agriculture human society began to function as a superorganism functioning as a single unit designed by social natural selection to produce economic surplus where environmental conditions were permitted early human agricultural societies followed the same pattern as a few social insects and exhibited explosive population growth complex and detailed division of labor intensive resource exploitation territorial expansion and a social organization favoring the survival and growth of the supergroup over the well being of individuals within the group similar economic forces lie behind ultrasociality in social insects and humans increased productivity from the division of labor increasing returns to scale and the exploitation of stocks of productive resources exploring the evolutionary mechanisms behind ultrasociality offers insights into the growth imperative that threatens the stability of the earth s life support systems

efficiency and the role of default when security markets are incomplete this paper argues that default plays an important positive role in the economy if markets are incomplete and traders are only able to enter into contracts that they will be able to execute regardless of future events contingent contracting may be severely restricted moreover opening new markets may not relieve these restrictions default promotes efficiency in a way that opening new markets does not by making it possible for traders to enter into contracts that they will be able to execute with high probability but not with certainty copyright 1993 by american economic association

the redistributive roles of unemployment insurance and the dynamics of voting abstract public unemployment insurance is analyzed as the majority voting equilibrium policy of a dynamic stochastic economy abstracting from incentive effects we focus on redistribution some results are because of the distribution of heterogeneous employment opportunities public insurance may be democratically chosen even if complete private markets exist and because of the dynamics even when agents are intrinsically homogeneous the equilibrium benefit level or duration benefit schedule deviates from what has been described as optimal in the literature the effects of differences in the average frequency or duration of unemployment on equilibrium taxes and benefits are investigated with some unanticipated results

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

endogenous borrowing constraints with incomplete markets this article develops ways to endogenize the borrowing constraints used in a class of computable incomplete markets models we allow the constraints to depend on an investor s characteristics such as time preference risk aversion and income streams the proposed constraint can be interpreted as a borrowing limit within which an investor has no incentive to default using a numerical algorithm we find that for an array of structural parameters the endogenous borrowing constraints can be much less stringent than the ad hoc borrowing constraints adopted by the existing studies

the joint determination of household membership and market work the case of young men except in special cases market work and household membership are jointly chosen a nash bargaining model of family behavior is used to specify stochastic structural relationships two indirect utility functions and a market and a reservation wage function that jointly determine work consumption and household membership the maximum likelihood estimates of the implied trinomial probit model differ sharply from those obtained when either market work or household membership is taken as exogenous this application to white male youths from the national longitudinal surveys shows the insurance function of families parents insure their sons against poor market opportunities

de growth some suggestions from the simpler way perspective abstract it is argued that there are some important issues which the current de growth literature neglects the first is the sheer magnitude of the global predicament which determines not just the insufficiently recognized difficulty of the transition task but also that the goals and means must take particular and largely unrecognized forms the goal cannot be reform of the existing society it must be transition to a radically different kind of society one labeled here as a radically simpler way current discussion indicates little recognition of this point similarly there are coercive logical implications for transition strategy and these indicate that currently dominant transition assumptions are mistaken the key element is not economic or political change it is cultural change these claims are shown to be logically implied by basic limits to growth considerations

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

does option compensation increase managerial risk appetite this paper solves the dynamic investment problem of a risk averse manager compensated with a call option on the assets he controls under the manager s optimal policy the option ends up either deep in or deep out of the money as the asset value goes to zero volatility goes to infinity however the option compensation does not strictly lead to greater risk seeking sometimes the manager s optimal volatility is less with the option than it would be if he were trading his own account furthermore giving the manager more options causes him to reduce volatility managers with convex compensation schemes play an important role in financial markets this paper solves for the optimal dynamic investment policy for a risk averse manager paid with a call option on the assets he controls the paper focuses on how the option compensation impacts the manager s appetite for risk when he cannot hedge the option position on one hand the convexity of the option makes the manager shun payoffs that are likely to be near the money under the optimal policy the manager either significantly outperforms his benchmark or else incurs severe losses furthermore in examples of optimal trading strategies asset volatility goes to infinity as asset value goes to zero yet option compensation does not strictly lead to greater risk seeking as asset value grows large or if the evaluation date is far away the manager moderates asset risk for example if the manager has constant relative risk aversion crra asset volatility converges to the merton constant as asset value goes to infinity in some situations the manager actually chooses a lower asset volatility than he would if he were investing on his own because the leverage inherent in his option magnifies his exposure to the asset volatility in addition with all constant or decreasing absolute risk averse utility functions from the hyperbolic absolute risk averse hara class giving the manager more options causes him to reduce asset volatility in the crra case for example the manager targets a fixed volatility for his personal

degrowth and techno business model innovation the case of riversimple there is an emergent understanding that humanity has precipitated an anthropocene such that we are now operating in a reduced space for humanity in which urgent action is required this case study paper links degrowth technological innovation business model innovation and corporate governance the arguments are illustrated with the case of an embryonic vehicle and mobility business called riversimple the paper shows that radical technology innovations in the vehicle itself are achieved by underlying principles that focus on mass decompounding powertrain de coupling whole system design and low volume production systems the characteristics of the technologies are fundamental to and in part derive from the business model adopted by the case and the governance structures designed to avoid the primacy usually afforded to returns to financial shareholders while the case is embryonic the paper argues that an important possible contribution is the ability to commence a disruptive transition to a degrowth future from within existing legal frameworks social practices cultural expectations and physical infrastructures
