the role of risk preferences in pay to bid auctions we analyze a new auction format in which bidders pay a fee each time they increase the auction price bidding fees are the primary source of revenue for the seller but produce the same expected revenue as standard auctions assuming risk neutral bidders if risk loving preferences are incorporated in the model expected revenue increases our model predicts a particular distribution of ending prices which we test against observed auction data the degree of fit depends on how unobserved parameters are chosen in particular a slight preference for risk has the biggest impact in explaining auction behavior suggesting that pay to bid auctions are a mild form of gambling this paper was accepted by peter wakker decision analysis

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

strategic behavior in contests comment almost by definition contests involve strategy this is especially true in contests between unevenly matched contenders in a recent article avinash dixit 1987 explored strategic commitment in contests between a favorite and an underdog the favorite is defined as the player whose chance of victory exceeds one half at the nash equilibrium an underdog s chance is less than one half dixit concludes that if the favorite has the opportunity to move first then he will overcommit effort compared with the nash equilibrium an important implication of the favorite overcommitting effort is that strategic behavior leads to greater social costs see gordon tullock 1980 the opposite holds if the underdog has the opportunity to move first this paper demonstrates that the favorite will never overcommit effort given endogenous order of moves the favorite finds it advantageous to wait until the underdog moves surprisingly the underdog s best strategy is not to wait but to make the first move throwing the first punch the equilibrium order of play is for the underdog to move before the favorite in this equilibrium one never observes overcommitment of effort consequently extending dixit s model to allow for endogenous order of moves suggests that strategic behavior in contests will lead to undercommitment compared with nash behavior

the solution to the tullock rent seeking game when r 2 mixed strategy equilibria and mean dissipation rates in tullock s rent seeking model the probability a player wins the game depends on expenditures raised to the power r we show that a symmetric mixed strategy nash equilibrium exists when r 2 and that overdissipation of rents does not arise in any nash equilibrium we derive a tight lower bound on the level of rent dissipation that arises in a symmetric equilibrium when the strategy space is discrete and show that full rent dissipation occurs when the strategy space is continuous our results are shown to be consistent with recent experimental evidence on the dissipation of rents

a note on comparative downside risk aversion abstract we provide comparative global conditions for downside risk aversion which are similar to the ones studied by ross for risk aversion we define a coefficient of downside risk aversion and study its local properties

risk aversion and prudence in rent seeking games this paper considers a common n agent symmetric rent seeking game it derives conditions so that risk aversion and risk always decrease rent seeking efforts these conditions hold for any regular contest success function when risk averse rent seekers are also prudent under n 2 prudence is a necessary and sufficient condition for risk aversion to decrease rent seeking efforts compared to risk neutrality an intuition for this result is given based on a self protection model

chaos in oil prices evidence from futures markets abstract we test for the presence of low dimensional chaotic structure in crude oil heating oil and unleaded gasoline futures prices from the early 1980s evidence on chaos will have important implications for regulators and short term trading strategies while we find strong evidence of non linear dependencies the evidence is not consistent with chaos our test results indicate that arch type processes with controls for seasonal variation in prices generally explain the non linearities in the data we also demonstrate that employing seasonally adjusted price series contributes to obtaining robust results via the existing tests for chaotic structure maximum likelihood methodologies that are robust to the non linear dynamics lend support for samuelson s hypothesis on contract maturity effects in futures price changes however the tests for chaos are not found to be sensitive to the maturity effects in the futures contracts the results are robust to controls for the oil shocks of 1986 and 1991

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

an experimental investigation of asymmetric contests abstract contest theory has been used in industrial organization to describe phenomena like r d races or efforts to defend a monopoly position when pricing behavior is constrained by regulators competition can also take the form of a contest this paper reports on an experimental test of the effects of asymmetry in the tullock contest success function both the simultaneous move and sequential move frameworks are considered despite high levels of overbidding across the different conditions the introduction of asymmetries in the contest function generates experimental behavior on aggregate qualitatively consistent with the theoretical predictions at the individual level behavior seems divided into those subjects who bid very high amounts and those who bid very low amounts

all pay auctions an experimental study this paper reports the results of a repeated all pay auction game the auction form used is the simplest possible complete information perfect recall and common value our main findings are that in such an auction over bidding is quite drastic and the seller s revenue depends strongly on the number of bidders in early stages however after a few rounds of play this dependence completely disappears and the seller s revenue becomes independent of the number of participants the results are confronted with two solution concepts of economic theory the nash equilibrium and the symmetric logit equilibrium 2005 published by elsevier b v

the value of commitment in contests and tournaments when observation is costly we study the value of commitment in contests and tournaments when there are costs for the follower to observe the leader s behavior in a contest the follower can pay to observe the leader s effort but cannot observe the effectiveness of that effort in a tournament the follower can pay to observe the effectiveness of the leader s effort but not the effort itself we show that this distinction matters significantly when observation is costly the value of commitment vanishes entirely in sequential and endogenous move contests regardless of the size of the observation cost by contrast in tournaments the value of commitment is preserved completely provided that the observation costs are sufficiently small

contests as selection mechanisms the impact of risk aversion abstract we investigate how individual risk preferences affect the likelihood of selecting the more able contestant within a two player tullock contest our theoretical model yields two main predictions first an increase in the risk aversion of a player worsens her odds unless she already has a sufficiently large advantage second if the prize money is sufficiently large a less able but less risk averse contestant can achieve an equal or even higher probability of winning than a more able but more risk averse opponent in a laboratory experiment we confirm both the non monotonic impact and the compensating effect of risk aversion on winning probabilities our results suggest a novel explanation for the gender gap and the optimality of limited monetary incentives in selection contests

higher order generalizations of arrow pratt and ross risk aversion a comparative statics approach abstract we analyze comparative risk aversion in a new way through a comparative statics problem in which for a cost agents can shift from an initial probability distribution toward a preferred distribution the ross characterization arises when the original distribution is riskier than the preferred distribution and the cost is monetary and the arrow pratt characterization arises when the original distribution differs from the preferred distribution by a simple mean preserving spread and the cost is a utility cost higher order increases in risk lead to higher order generalizations and the comparative statics method yields a unified approach to the problem of comparative risk attitudes

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

trends in the development of ecological economics from the late 1980s to the early 2000s abstract as the contributions to ecological economics are very diverse recent years have seen some discussion on both how to delimit the field and in which direction it should develop the intention with this paper is to contribute to the discussion by outlining important trends in the development of the field from the late 1980s to the early 2000s the study is inspired by other studies in the sociology and history of science in particular by the theoretical framework regarding scientific fields as reputational organizations which draws attention to both cognitive and social aspects of the formation of a field the basis for the paper is a combination of literature studies interviews with key researchers in the field and participant observations the paper outlines the characteristic cognitive features of ecological economics at the time of the birth of the field it is then described how the development in ecological economics was influenced by broader social factors during the following years and how the field was shaped by the inflow and outflow of different groups of researchers the emergence of different research programmes is outlined as is the organizational development finally the characteristics of ecological economics are summarized and the future prospects are briefly assessed

gordon tullock and experimental economics gordon tullock s research has substantially influenced the development of economic science in general and experimental economics in particular we present the first comprehensive survey of this significant achievement we show how tullock s research in bioeconomics influenced later developments in neuroeconomics and how his pioneering work on rent seeking generated a literature of laboratory tests of his hypothesis we also describe tullock s own experiments and draw attention to his early insights on trust games

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

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

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

risk attitudes and heterogeneity in simultaneous and sequential contests we prove existence and uniqueness of equilibrium in rent seeking contests in which players are heterogeneous in both risk preferences and production technology given identical linear production technology if the number of risk loving players is large enough the aggregate investment in equilibrium will exceed the rent and all risk neutral and risk averse players will exit the contest in simultaneous and sequential contests with two players we can identify the favorite and underdog based on both players preference parameters our theoretical results suggest that subjects in some recent contest experiments behaved as if they were risk loving

impact of speculator s expectations of returns and time scales of investment on crude oil price behaviors abstract based on time series of crude oil prices daily spot this paper analyses price fluctuation with two significant parameters speculators time scales of investment and e speculators expectations of return by using zipf analysis technique specifically by mapping returns of prices into 3 alphabeted sequences absolute frequencies and 2 alphabeted sequences relative frequencies containing the fundamental information of price fluctuations this paper empirically explores parameters and identifies various types of speculators cognition patterns of price behavior in order to quantify the degree of distortion a feasible reference is proposed an ideal speculator finally this paper discusses the similarities and differences between those cognition patterns of speculators and those of an ideal speculator the resultant analyses identify the possible distortion of price behaviors by their patterns

oil prices and news based uncertainty novel evidence abstract in this paper using news implied volatility nvix as a key variable to measure news based uncertainty we investigate whether the world price of oil and three classical oil shocks affect news based uncertainty or vice versa our analysis is conducted through the news mechanism that is unrelated to fundamentals this research contributes to the literature on the effect of oil prices on news based uncertainty by studying the dynamics in both the time and frequency domains using the wavelet coherence analysis our results illustrate that oil prices exhibit a statistically and economically significant leading role on nvix especially in the long run further we distinguish the different impacts of oil shocks and find that the oil supply and aggregate demand shocks usually play a leading role on relatively long term nvix while the oil specific demand shocks are sensitive to the fluctuations of nvix we also find that the rules of comovement between oil prices oil shocks and news based uncertainty change at different frequencies and times they usually move together in opposite directions with the exception of the oil supply shocks and nvix these findings apply to both oil spot and futures markets our results present new and interesting implications for investors and policy makers by supporting the news reallocation channel as an important transmission mechanism from oil markets

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

long term memories of developed and emerging markets using the scaling analysis to characterize their stage of development the scaling properties encompass in a simple analysis many of the volatility characteristics of financial markets that is why we use them to probe the different degree of markets development we empirically study the scaling properties of daily foreign exchange rates stock market indices and fixed income instruments by using the generalized hurst approach we show that the scaling exponents are associated with characteristics of the specific markets and can be used to differentiate markets in their stage of development the robustness of the results is tested by both monte carlo studies and a computation of the scaling in the frequency domain

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

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

do emerging markets matter in the world oil pricing system evidence of imported crude by china and india abstract this paper provides empirical evidence on the changing structure of world oil price system by identifying an additional driver emerging market factor we choose china and india as a representative of emerging markets to examine if the quantity of crude oil imported by china and india is significant in the existing oil pricing system kaufmann et al 2004 our data starts from january 2002 and ends in march 2010 which includes the oil shock of 2007 2008 we utilize cointegration and error correction model framework developed by engle granger 1987 and gregory hansen 1996 in the analysis our results indicate that demand from emerging markets has become a significant factor in the world oil pricing system since 2003 this result is significant as it lends empirical support to the widely held conjecture that the oil shock of 2007 2008 is a demand led shock hamilton 2009 our result also has significant policy implications that go beyond the oil shock the emerging market factor is there to stay and reflects the changing power between emerging and developed economies in the world economic system as a result of decades of fast economic development in the former it will certainly influence policy issues related to oil and beyond

risk lovers and the rent over investment puzzle in this paper we prove existence and uniqueness of equilibrium in a rent seeking contest given a class of heterogeneous risk loving players we explore the role third order risk attitude plays in equilibrium and find that imprudence is sufficient for risk lovers to increase rent seeking investment above the risk neutral outcome moreover we show that rent can be fully dissipated in a standard tullock contest played by a large number of risk lovers

experimental comparison of multi stage and one stage contests this article experimentally studies a two stage elimination contest and compares its performance with a one stage contest contrary to the theory the two stage contest generates higher revenue than the equivalent one stage contest there is significant over dissipation in both stages of the two stage contest and experience diminishes over dissipation in the first stage but not in the second stage our experiment provides evidence that winning is a component in a subject s utility a simple behavioral model that accounts for a non monetary utility of winning can explain significant over dissipation in both contests it can also explain why the two stage contest generates higher revenue than the equivalent one stage contest

rent seeking incentives in share contests abstract this article investigates share contests in our framework we allow contestants to have more general preferences than have been used in the literature previous approaches have the unfortunate characteristic that contestants marginal rates of substitution between the rent share allocated by the contest and their effort is constant regardless of the size of the rent share this results in a conventional wisdom larger rents command more effort by providing a more general framework we show the reverse may also be true and we derive the conditions under which this is the case our approach then allows us to rationalize within a standard contest framework observations that rents might be more hotly contested when they become scarcer as has evidently been the case with the recent global contraction of public funds available for public policy

a wavelet analysis of mean and volatility spillovers between oil and brics stock markets this paper investigates the spillover effects of volatility and shocks between oil prices and the brics stock markets using multivariate approach and wavelet analysis at different time horizons hence we combine a multivariate arma garch model and wavelet multiresolution analysis to study this phenomenon a bivariate arma 1 1 garch 1 1 cdcc student t model was joined with modwt filter to capture a broad range of possible spillover effects in mean and variances of level prices at various time horizons generally empirical results provide strong evidence of time varying volatility in all markets under study however our proposed approach shows that oil price and stock market prices are directly affected by their own news and volatilities and indirectly affected by the volatilities of other prices and wavelet scale the results show also that mean and volatility spillover effects was decomposed into many sub spillovers on different time scales according to heterogeneous investors and market participants the practical implications of this study are critical innovative and useful for the local and international investors and also for the portfolio managers they can utilize this study to formulate the optimal oil bricks stock portfolios as well as lead to more accurate predictions of volatility spillovers patterns also in developing their hedging strategies

degrowth taking stock and reviewing an emerging academic paradigm degrowth has evolved within a decade from an activist movement into a multi disciplinary academic paradigm however an overview taking stock of the peer refereed degrowth literature is yet missing here we review 91 articles that were published between 2006 and 2015 we find that the academic degrowth discourse occupies a small but expanding niche at the intersection of social and applied environmental sciences the discourse is shaped by authors from high income mainly mediterranean countries until 2012 articles largely constitute conceptual essays endorsed by normative claims more recently degrowth has branched out into modelling empirical assessments and the study of concrete implementations authors tend to agree in that economic growth cannot be sustained ad infinitum on a resource constraint planet and that degrowth requires far reaching societal change whether degrowth should be considered as a collectively consented choice or an environmentally imposed inevitability constitutes a major debate among degrowth thinkers we argue that the academic discourse could benefit from rigid hypotheses testing through input output modelling material flow analysis life cycle assessments or social surveys by analyzing the potentials for non market value creation and identifying concrete well being benefits the degrowth discourse could receive wider public support and contribute to a paradigmatic change in the social sciences

strategic behavior in contests comment in an influential paper avinash dixit 1987 considers a class of symmetric two player contests in which each player s effort xi influences the probability of winning a prize valued at k 0 letting p x1 x2 denote the probability 1 that player 1 wins the expected payoffs of the two players are p1 5 p x1 x2 k 2 x1 and p2 5 1 2 p x1 x2 k 2 x2 dixit s main result is that if there is perfect symmetry between the players and each player s effort has a positive but diminishing marginal effect on his or her probability of winning i e

risk aversion heterogeneity and contests we introduce a novel method of modellingcontests that avoids the complexitiesencountered by the best response function approach we analyse contests in which i there are many risk averse players ii attitudes to risk may differ acrossindividuals and iii the technology thattransforms rent seeking effort intoprobability of winning may also differacross individuals we establish that ifevery player has a constant degree ofabsolute risk aversion a uniqueequilibrium exists we also establishcomparative static results and examine howthe level of rent dissipation is affectedby the heterogeneity of attitudes towardsrisk and the precise nature of the technology

assessing the degrowth discourse a review and analysis of academic degrowth policy proposals abstract debates on ecological and social limits to economic growth and new ways to deal with resource scarcity without compromising human well being have re emerged in the last few years central to many of these is a call for a degrowth approach in this paper a framework is developed to support a systematic analysis of degrowth in the academic literature this article attempts to present a clearer notion of what the academic degrowth literature explores by identifying organising and analysing a set of proposals for action retrieved from a selection of articles the framework is applied to classify proposals according to their alignment to ecological economics policy objectives sustainable scale fair distribution and efficient allocation type of approach top down versus bottom up and geographical focus local national or international a total of 128 peer reviewed articles focused on degrowth were reviewed and 54 that include proposals for action were analysed the proposals identified align with three broad goals 1 reduce the environmental impact of human activities 2 redistribute income and wealth both within and between countries and 3 promote the transition from a materialistic to a convivial and participatory society the findings indicate that the majority of degrowth proposals are national top down approaches focusing on government as a major driver of change rather than local bottom up approaches as advocated by many degrowth proponents the most emphasised aspects in the degrowth literature are related to social equity closely followed by environmental sustainability topics such as population growth and the implications of degrowth for developing nations are largely neglected and represent an important area for future research moreover there is a need for a deeper analysis of how degrowth proposals would act in combination

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

random fractal structures in north american energy markets this paper uses daily observations on west texas intermediate wti crude oil prices at chicago and henry hub natural gas prices at la over the deregulated period of the 1990s and various tests from statistics and dynamical systems theory to support a random fractal structure for north american energy markets in particular this evidence is supported by the vassilicos et al 1993 multifractal structure test and the ghashghaie et al nature 381 1996 767 turbulent behavior test

sorting incentives and risk preferences evidence from a field experiment abstract we conducted experiments within a firm to measure the risk preferences of workers who face substantial daily income risk we find that these workers are significantly more risk tolerant than individuals from the broader population this is consistent with sorting risk tolerant workers are attracted to high risk occupations

the incidence of overdissipation in rent seeking contests tullock s analysis of rent seeking and overdissipation is reconsidered we show that while equilibrium strategies do not permit overdissipation in expectation for particular realizations of players mixed strategies the total amount spent competing for rents can exceed the value of the prize we also show that the cross sectional incidence of overdissipation in the perfectly discriminating contest ranges from 0 50 to 0 44 as the number of players increases from two to infinity thus even though the original analysis of overdissipation is flawed there are instances in which rent seekers spend more than the prize is worth

economic de growth vs steady state economy in recent years the concept of economic de growth decroissance based on the literature of nicolas georgescu roegen e g 1 3 has found a revival in france italy spain and other countries in the popular as well as in the academic literature therein authors took on board georgescu roegens categorical rejection of a steady state economy sse as proposed by herman daly 4 they argue that economic degrowth is the only viable alternative goal to the growing economy this position is challenged in this article and it is concluded that the two concepts are in fact complements economic de growth is not a goal in itself but the rich north s path towards a globally equitable sse moreover the de growth literature can benefit from the strong economic historic roots of the sse and from daly s macroeconomic concepts while in return being able to give lessons about bottom up approaches this would be particularly important for the population issue where daly proposes limited birth licences unfortunately statements on demography are inconsistent and underdeveloped in the de growth literature further it is concluded that most criticisms of the sse are due to a too narrow and technocratic interpretation of the concept instead the sse should be defined as a quasi steady state resting in a dynamic equilibrium and as an unattainable goal which can and probably should be approximated

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
