stabilization policy a reconsideration i introduction in 1936 keynes s general theory explained how fiscal and monetary policy could be used to end depressions since that time no developed country has ever seen a downturn on the scale of the 1930s the general theory was not just a how to book on the avoidance of depressions it was an argument for stabilization policy itself the years since the general theory have seen a revolt against keynesian economics in a revisionist mode milton friedman argued that countercyclical policy cannot affect the average level of unemployment and output robert lucas and thomas sargent 1979 went further contending that it is not only impossible to increase average output it is also impossible to stabilize it more recently lucas 1987 2003 has argued that policies to stabilize output even if effective would yield negligible welfare gains thus stabilization policy should not be a macroeconomic priority lucas s conclusion notwithstanding stabilization policy has long been an explicit or implicit objective of monetary policy in most industrial countries even including those countries with inflation targets the volatility of output has in fact declined in most major industrial countries since the mid 1980s and monetary policy arguably deserves at least partial credit see bernanke 2004 mirroring practice monetary policy research commonly takes it as given that along with price stability stabilization policy the minimization of squared deviations of output around potential is an appropriate policy objective see for example clarida et al 1999 in this article we explore the economic rationale for stabilization as a policy goal concluding that it does in fact deserve high policy priority we survey a large body of literature that critiques the validity of key assumptions in lucas s argument we also offer suggestive evidence that stabilization policy can significantly reduce average levels of unemployment by providing stimulus to demand in circumstances where unemployment is high but underutilization of labor and capital does little to lower inflation a monetary policy that vigorously fights high unemployment should however also be complemented by a policy that equally vigorously fights inflation when it rises above a modest target level the federal reserve act thus wisely enunciated price stability and maximum employment as twin goals for monetary policy ii the case against stabilization policy macroeconomic analysis typically assumes that social welfare depends negatively on both inflation above a modest target level here assumed zero and unemployment above some minimum socially efficient level for example a standard social welfare function is the discounted sum of period losses l sub t of the form see among others barro and gordon 1983 pp 592 93 1 l sub t a u sub t 1 k u sup 2 b pi sup 2 sub t where u sub t and pi sub t are the unemployment and inflation rates in period t and u sup is the natural rate of unemployment the coefficient k is positive reflecting the desirability of unemployment below the natural rate because real economies deviate in many respects from perfect competition the natural rate of unemployment is likely to exceed the socially optimal unemployment rate for example with monopolistic competition goods are underproduced because they are priced above marginal cost so potential output is inefficiently low and equilibrium unemployment is too high standard macroeconomic analysis additionally assumes that inflation is determined by an expectations augmented accelerationist phillips curve of the form 2 pi sub t pi sup e sub t f u sub t u sup epsilon sub t where pi sup e sub t is the expected inflation rate at time t with expectations formed at t 1 and epsilon sub t captures supply shocks to the phillips curve at t

income resources and electricity mix this paper presents evidence on a national level electricity ladder which sees countries transition toward coal and natural gas and finally nuclear power and modern renewables such as wind power for their electricity needs as they develop the extent to which countries climb the electricity ladder is dependent on energy endowments the results imply that the environmental implications of economic development differ in countries with different energy resource endowments an effective global carbon mitigation strategy will require developing countries to leapfrog the middle rungs of the electricity ladder

investments holdup and the form of market contracts the authors analyze incomplete contracts to induce efficient investment with exogenous switching costs fixed price contracts are efficient generate some rigidity in prices are renegotiated intermittently by possibly small amounts and when inflation is positive generate asymmetric responses to shocks all consistent with evidence on prices and wages with two sided specific investments efficiency requires prices to have sufficient escalator clauses to avoid renegotiation as observed in many long term contracts a third case with one sided specific investments can generate take or pay contracts and explain why firms sometimes pay for specific investments that appear to benefit employees directly

real and nominal wage rigidities and the rate of inflation evidence from west german micro data the paper examines real and nominal wage rigidities we estimate a switching regime model in which the observed distribution of individual wage changes computed from west german register data for 1976 1997 is generated by simultaneous processes of real nominal or no wage rigidity and measurement error the fraction of workers facing wage increases that are due to nominal but mostly real wage rigidity is substantial the extent of real rigidity rises with inflation whereas the opposite holds for nominal rigidity overall the incidence of wage rigidity which accelerates unemployment growth is most likely minimized in an environment with moderate inflation

the taylor principle fights back part ii abstract the existing literature holds that the taylor principle often leads to indeterminacy in new keynesian models that allow for capital accumulation and limited asset market participation this conclusion is special however to the case of continuous full employment when the assumption of perfect wage flexibility is relaxed very slightly so that the labor market clears quickly but not instantaneously determinacy is the norm the threat of indeterminacy is limited to a tiny irrelevant corner of the parameter space where the elasticity of labor supply is unusually high and real wage adjustment is unbelievably fast everywhere else the taylor principle guarantees a unique rational expectations equilibrium the dramatic difference in results reflects the sensitivity of the monetary transmission mechanism to the speed of adjustment in the labor market

unemployment and productivity in the long run the role of macroeconomic volatility abstract this paper presents a new empirical regularity between the volatility of productivity growth and long run unemployment for a given level of long run productivity growth a theoretical framework based on asymmetric real wage rigidities is shown to have the potential to rationalize this finding the model tends to fit u s long run unemployment better than a specification based on long run productivity growth only especially during the great moderation and the great recession

demand pull technology push and government led incentives for non incremental technical change abstract rising expectations about future demand for new technologies increase the incentives for investments in innovation by enlarging payoffs to successful innovations how well does this notion of demand pull apply to non incremental technological change when demand is largely attributable to actions by governments in this case inventors of the most important inventions did not respond positively to strong demand pull policies filing of highly cited patents declined precipitously just as demand for wind power created a multi billion dollar market three explanations for this apparent inconsistency with the demand pull hypothesis played a role 1 the rapid convergence on a single dominant design limited the market opportunity for non incremental technical improvements 2 even though the policies implemented were stringent enough to stimulate demand uncertainty in their longevity dampened the incentives for inventions that were likely to take several years to pay off and 3 alternative explanations such as declining r d funding and weakening presidential engagement on energy appear to have been important

wage rigidity in canadian collective bargaining agreements the authors search information on the provisions of 10 947 wage contracts signed in the canadian unionized sector between 1976 and 1999 for evidence of downward nominal wage rigidity the disinclination of wages to fall in nominal dollars below their established level over the sample period real wage reductions were common but nominal wage reductions were rare the probability of downward nominal wage rigidity increased substantially during low inflation periods during such periods apparently there was no reduction in the incidence of real wage cuts but the magnitude of those cuts was modest suggesting a lesser ability of wages to adjust to labor market conditions than at other times

escalators and elevators a phillips curve for keynesians the negatively sloped long run phillips curve remains an issue of contention this paper presents a theoretical model of the phillips curve in which nominal demand growth reduces unemployment caused by stochastic shifts of demand between sectors the model can be understood through the following metaphor keynesian economies are escalator economies in which markets adjust back to equilibrium slowly so that nominal demand growth presents a means of speeding up the escalator process contrastingly new classical economies as set forth by e g lucas 1973 are elevator economies in which adjustment is instantaneous consequently there is no role for nominal demand growth in the adjustment process and to the extent that policy sponsored nominal demand growth is uncertain it may actually disrupt the economy by sending the elevator to the wrong floor

interest rates and the fisher effect in india an empirical study abstract this study throws light on the importance of adjustment lags variability of inflation changes in real income etc in the empirical estimation of fisher hypothesis variability of inflation has a significant negative impact on both short and long term interest rates in a developing economy like india the philips curve effect has not been operative in a developing country

the incidence of nominal and real wage rigidities in great britain 1978 98 this paper analyzes the extent of rigidities in wage setting in great britain over the 1980s and 1990s our estimation strategy which generalizes the work of altonji and devereux 2000 models the notional wage growth distribution the distribution of nominal wage growth that would occur in the absence of rigidities in pay while allowing for the presence of measurement error in the data the model then allows for the possibility that the nominal wage growth of a fraction of the workforce may be subject to a nominal or real downward rigidity our model suggests that real rigidities in wage setting are more prevalent than nominal rigidities although the incidence of these real wage rigidities has fallen gradually over time if firms cannot cut real wages in response to negative demand shocks they may resort to laying off workers our results support this microfoundation of the wage unemployment phillips curve workers who are more likely to be protected from wage cuts are also more likely to lose their jobs

loss aversion and the asymmetric transmission of monetary policy there is widespread evidence that monetary policy exerts asymmetric effects on output over contractions and expansions in economic activity while price responses display no sizeable asymmetry to rationalize these facts we develop a dynamic general equilibrium model where households utility depends on consumption deviations from a reference level below which loss aversion is displayed state dependent degrees of real rigidity and elasticity of intertemporal substitution in consumption generate competing effects on output and inflation contractions face the central bank with higher responsiveness of output to interest rate changes as well as a flatter aggregate supply schedule

balancing demand pull and supply push measures to support renewable electricity in europe abstract increasing the share of renewable energy is deemed essential to reduce the carbon intensity of the current electricity mix the promotion of renewable energy technologies should thus be as effective and efficient as possible therefore support schemes should explicitly consider the balance between demand pull e g production subsidies and supply push efforts public rdd the cumulative pull push ratio for biogas is about 700 in the 5 year lag case and about 1200 in the other cases 10 yr lag or more although the debate on optimal rd d efforts is not conclusive and very sector specific it is relevant to compare our findings to average pull push ratios of about 20 in the engineering sector overall we can safely conclude that european governments should critically evaluate current renewables subsidy schemes and increase public rd d investments to support next waves of renewable energy technologies

wage rigidity inflation and institutions we study the possible existence of downward nominal wage rigidity dnwr at wage growth rates different from zero in aggregate data even if dnwr prevails at zero for individual workers compositional effects might lead to falling aggregate wages while changes in relative wages combined with dnwr might lead to positive aggregate wage growth we explore industry data for 19 oecd countries over the 1971 2006 period we find evidence for a floor on nominal wage growth at 6 percent in the 1970s and 1980s at 1 percent in the 1990s and at 0 5 percent in the 2000s furthermore we find that dnwr is stronger in country years with strict employment protection legislation high union density centralized wage setting and high inflation

downward nominal wage rigidity evidence from canada 1901 1950 this paper tests for the presence of downward nominal wage rigidity in canadian wage data for 26 occupations in 38 cities from the first half of the 20th century the sample is of particular interest as it contains periods with average inflation rates that are close to zero as well as two sharp deflations results from a variety of different tests indicate that wage change distributions are consistent with the presence of downward nominal wage rigidity however for two subsamples containing sharp declines in output and prices estimates of the extent of downward nominal wage rigidity are much lower this suggests that downwards adjustments did occur during times of severe depression and deflation

nominal wage rigidity and the rate of inflation using the accurate and extensive data available in the uk new earnings survey this paper investigates the extent to which nominal wages are downwardly rigid and whether such rigidity interferes with necessary real wage adjustments when inflation is low despite the substantial numbers of individuals whose nominal wages fall from one year to the next we find that if long run inflation is one percent higher the number of individuals with negative real pay growth increases by around 1 4 percent this is controlling for the median and dispersion of the real wage change distribution

how prevalent is downward rigidity in nominal wages international evidence from payroll records and pay slips in chapter 2 of the general theory of employment interest and money 1936 john maynard keynes put forward an assumption of downward rigidity in nominal wages as the cornerstone of his analysis of what happens in the labor market over the business cycle according to his analysis if the real value of the existing nominal wage exceeds the market clearing level downward nominal rigidity prevents arbitrage towards that level instead employment is determined by the short side of the market the labor demand side and the excess supply of labor at that wage manifests as high unemployment keynes s brief theoretical account of why workers refuse to accept a nominal wage reduction even when unemployment is the consequence involved workers concern about their wages relative to their reference group keynes did not directly address why workers would be so preoccupied with their relative wage that they would prefer job loss even during a recession to accepting a wage cut keynes s empirical basis for his assumption was that whether logical or illogical experience shows that this is how labour in fact behaves he did not provide any quantitative evidence to support this observation

inflation and unemployment the world economy today is vastly different from the 1930s when seymour harris the chairman of this meeting infected me with his boundless enthusiasm for economics and his steadfast confidence in its capacity for good works economics is very different too both the science and its subject have changed and for the better since world war ii but there are some notable constants unemployment and inflation still preoccupy and perplex economists statesmen journalists housewives and everyone else the connection between them is the principal domestic economic burden of presidents and prime ministers and the major area of controversy and ignorance in macroeconomics i have chosen to review economic thought on this topic on this occasion partly because of its inevitable timeliness partly because of a personal interest reaching back to my first published work in 1941

explaining government choices for promoting renewable energy abstract many advanced industrialized countries have in recent years experienced a significant expansion of electricity production from renewables yet we know quite little about the dynamics of the underlying policychoices in this area using new data on adoptions and changes in feed in tariff and green certificate schemes in 26 advanced industrialized countries over 20 years we examine both domestic driving forces as well as international determinants the findings suggest that three factors play a particularly important role in pushing countries towards market based support systems characteristics of the existing energy supply system a federalist structure of the political system and eu membership particularly noteworthy is the finding that higher shares of fossil and nuclear energy in the national energy supply as well as higher co 2 intensity of the economy do not as we had expected stand in the way of policies for supporting renewables in electricity production to the contrary they increase the likelihood of a country adopting such policies we also find however that higher economic growth and higher growth in solar and wind energy capacity tend to reduce the political appetite for reforms of existing schemes

demythologizing consumption practices how consumers protect their field dependent identity investments from devaluing marketplace myths marketplace myths are commonly conceptualized as cultural resources that attract consumers to a consumption activity or brand this theoretical orientation is prone to overstating the extent to which consumers identity investments in a field of consumption are motivated by an associated marketplace myth we provide a theoretical corrective to this tendency by investigating consumers who have become vested in a commercially mythologized consumption field through an incremental process of building social connections and cultural capital for these consumers the prevailing marketplace myth is experienced as a trivialization of their aesthetic interests rather than as a source of identity value in response they employ demythologizing practices to insulate their acquired field dependent social and cultural capital from devaluation our findings advance theorizations concerning marketplace myths and consumer identity work and explicate the sociocultural forces that deter consumers from abandoning a consump

how rigid are nominal wages evidence and implications for germany many recent attempts to find evidence on downward nominal wage rigidity in micro data have suffered from problems such as composition bias and the effects of measurement error in this paper a model of proportional downward nominal wage rigidity is developed which avoids these problems by taking into account the determinants of wage changes and the measurement process that leads to observable earnings changes we find a high degree of downward nominal wage rigidity in german micro data its real implications for individual expected wage growth the aggregate wage level and equilibrium unemployment have marked effects for rates of inflation lower than 3 percent

allocating discretionary time complementarity among activities analysis of complementarity among 50 discretionary activities suggests 1 the greater meaning of partial versus simple correlational measures 2 the validity of seven a priori sets of complements 3 the usefulness of multidimensionally scaled correlations in identifying two key activity dimensions intellectual effort and physical exertion and 4 implications for both marketing and public policy

on inflation and real price variability this paper studies the consequences of costly price adjustments for the variability of real prices accompanying inflation for constant elasticity demand and cost of production it is shown that a higher demand a lower cost of production or a lower cost of price adjustment leads to less intertemporal variability of real prices if the marginal cost of production does not increase too fast then the average real price is less than the real price that would prevail in the absence of inflation additionally a higher demand a lower cost of production or a lower cost of price adjustment leads to a higher level of real prices

the impact of r d on innovation for wind energy in denmark germany and the united kingdom this paper examines the impact of public research and development r d support on cost reducing innovation for wind turbine farms in denmark germany and the united kingdom uk first we survey the literature in this field the literature indicates that in denmark r d policy has been more successful than in germany or the uk in promoting innovation of wind turbines furthermore such studies point out that subsidy induced capacity expansions were more effective in the uk and denmark in promoting cost reducing innovation than in germany the second part of the paper describes the quantitative analysis of the impact of r d and capacity expansion on innovation this is calculated using the two factor learning curve 2flc model in which investment cost reductions are explained by cumulative capacity and the r d based knowledge stock time series data were collected for the three countries and organized as a panel data set the parameters of the 2flc model were estimated focusing on the homogeneity and heterogeneity of the parameters across countries we arrived at robust estimations of a learning by doing rate of 5 4 and a learning by searching rate of 12 6 the analysis underlines the homogeneity of the learning parameters enhancing the validity of the 2flc formulation

downward wage rigidity in italy micro based measures and implications using the 1985 99 whip data we find a sizable amount of downward wage rigidity in italy with a prevalence of real over nominal rigidity the results hold when real rigidity is identified either with reference to collective bargaining dispositions or to price inflation consistently with the labour market reforms of the early 1990s downward rigidities have become less important over time with the reduction in real rigidities more than offsetting the rise in nominal rigidities we also find that downward wage rigidities are positively related to labour reallocation and local unemployment rates hinting at the macroeconomic relevance of our estimates

the rise and decline of nations economic growth stagflation and social rigidities the years since world war ii have seen rapid shifts in the relative positions of different countries and regions leading political economist mancur olson offers a new and compelling theory to explain these shifts in fortune and then tests his theory against evidence from many periods of history and many parts of the world

the relationship between inflation and inflation uncertainty in the uk 1885 1998 abstract using a long series of uk inflation data i have provided strong evidence in favour of the hypothesis that inflationary periods are associated with high inflation uncertainty this result supports the friedman ball hypothesis and has important implications for the inflation output relationship provided that more inflation uncertainty leads to lower output

post unification wage growth in east germany following monetary union with west germany in 1990 the real wage of east german workers rose 83 i use the german socio economic panel data to investigate the determinants of wage growth and assess whether they are consistent with efficient restructuring although job changing rates were initially high the share of wage growth that accrued to movers was little higher than in the west suggesting that the incentives to move were too low for 1990 to 1991 the biggest gainers were low wage workers generally and women and the less educated specifically for 1991 to 1996 the biggest gainers were women and the better educated

on the asymmetric u shaped relationship between inflation inflation uncertainty and relative price skewness in the uk we investigate the asymmetric relationships between aggregate inflation and the second and third moments of the cross sectional distribution of relative prices using a modified calvo pricing model with regime dependent price rigidities calibration experiments reveal that the inflation standard deviation and inflation skewness relationships exhibit u shaped asymmetries around the historical mean inflation rate uk sectoral data support our results we conclude that monetary policy should target an inflation rate proximate to the common minima of these nonlinear relationships and that core inflation measures should not be used for policy purposes as they exclude much of the information contained in the higher moments

wage bargaining and nominal rigidities abstract delays in wage negotiations do not necessarily mean work stoppage production can continue under the terms of the old contract while the parties are bargaining holdout this holdout option is included in a strategic bargaining game in addition to strike and lock out threats integrating the bargaining model in a standard macroeconomic framework it turns out that holdout threats will prevail under certain circumstances in this case wages will be rigid in nominal terms so that an increase in aggregate nominal demand increases aggregate output

downward wage rigidities and optimal monetary policy in a monetary union this paper analyses the implications of heterogeneity in the type of downward wage rigidity nominal or real for optimal monetary policy in a monetary union with asymmetric wage adjustment costs indexation in one region of the union reduces optimal grease inflation in the presence of common productivity shocks large common shocks may have sizeable and persistent effects on the intra union terms of trade whereby the region characterized by downward real wage rigidity adjusts with a persistent loss of competitiveness in response to asymmetric productivity shocks there is no role for grease inflation because relative price changes facilitating the real wage changes dominate the adjustment mechanism

how strong is the macroeconomic case for downward real wage rigidity we explore the existence of downward real wage rigidity drwr at the industry level based on data from 19 oecd countries for the period 1973 1999 the results show that drwr compresses the distributions of industry wage changes overall as well as for specific geographical regions and time periods but there are not many real wage cuts that are prevented more important however drwr attenuates larger real wage cuts thus leading to higher real wages there is stronger evidence for downward nominal wage rigidity than for drwr real wage cuts are less prevalent in countries with strict employment protection legislation and high union density

aftershocks of monetary unification hysteresis with a financial twist abstract in the 1990s it was widely agreed that neither europe nor the united states satisfied the conditions for constituting an optimum currency area although the u s came closer bayoumi and eichengreen 1993 moderating this concern about europe was the fact that it was possible to distinguish a regional core and periphery using updated data we confirm that the united states remains closer to an optimum currency area more intriguingly the euro area shows striking changes in correlations and responses we interpret these as reflecting hysteresis with a financial twist in which the financial system causes aggregate supply and demand shocks to reinforce each other an implication is that the euro area needs vigorous coordinated regulation of its banking and financial systems by a single supervisor that monetary union without banking union will not work

wage policies of a russian firm and the financial crisis of 1998 evidence from personnel data 1997 to 2002 the authors use a rich personnel data set from a russian firm for the years 1997 to 2002 to analyze how the firm adjusts wages and employment during this period in which local labor market conditions changed in the aftermath of the financial crisis in 1998 they relate the development of turnover and wages for various employment categories to alternative models of wage and employment determination the authors argue that the firm s behavior is consistent with the predictions of efficiency wage models of the shirking and turnover type

beyond technology push and demand pull lessons from california s solar policy abstract the scale of the technological transformation required to reduce greenhouse gas emissions to safe levels while minimizing economic impacts necessitates an emphasis on designing climate policy to foster or at least not impede environmental innovation there is only a weak empirical base for policy makers to stand on regarding the comparative innovation effects of various climate policy options however empirical scholarship in environmental innovation is hindered by the complexity of both the innovation process and the interactions between the dual market failures of pollution and innovation that are in play and it appears that the field would benefit from the structure provided by a common lexicon this paper focuses on the issues related to policy categorization in this field these issues have received little attention in the literature despite their importance to making insights gained from empirical studies generalizable the paper reviews the origins strengths and weaknesses of the dominant policy typology of technology push versus demand pull instruments its primary contribution however is to assemble a comprehensive chronology of solar policy in california and its impacts on innovation where known and then use this as a basis for building a new policy categorization that takes advantage of the intuitive resonance of the dominant typology while encompassing the broader range of policy instruments that are employed in practice in order to stimulate environmental innovation the most noteworthy aspect of the new categorization is that it introduces a third category of environmental innovation policy instrument that focuses on improving the interface between technology suppliers and users this reflects developments in the economics of innovation literature as well as considerable evidence in the domain of distributed solar energy technologies that opportunism by some of the actors that work at this interface can be a barrier to innovation

more oil less democracy evidence from worldwide crude oil discoveries this article exploits variations in the timing and size of oil discoveries to identify the impact of oil wealth on democracy i find that discovering 100 billion barrels of oil approximately the initial endowment of iraq pushes a country s democracy level almost 20 percentage points below trend after three decades the estimated effect is larger for oilfields with higher quality oil and lower exploration and extraction costs however the estimates become less precise when oil abundance is measured by oil discovery per capita suggesting politicians may care about the level instead of the per capita value of oil wealth

bottlenecks and the phillips curve a disaggregated keynesian model of inflation output and unemployment benchmark macroeconomic models of output and inflation combine the demand side of the economy with aggregate supply equations based upon some version of the phillips curve in contrast to classical and new classical models such as lucas i972 and sargent 1979 chs i xii and xvi in which prices jump instantaneously to market clearing levels the gradual price adjustment approach represented by tobin 1972 laidler and parkin i975 section 4 barro and grossman 1976 ch 5 sargent 1979 ch ii and ch v i okun i98i and perry i983 take wages and or prices to be predetermined at an instant in time while their rates of change depend on the level of aggregate output in the prototype complete macroeconomic model incorporating this approach output is determined by aggregate demand equations while the augmented phillips curve specifies that prices move in a direction which will tend to return output to its equilibrium value this short run keynesian long run monetarist character is typical of many structural macroeconometric models it is the standard textbook account found for example in dornbusch and fischer i98i and is implicit in much current research there are fundamental questions of consistency in the type of model just described the central difficulty is that with wages and prices predetermined the non market clearing analysis ofbarro and grossman i 976 ch 2 and malinvaud i977 is applicable but in this world the aggregate demand equations are decisive only in the keynesian regime in the other regimes which must arise at high levels of aggregate demand the effective supplies of output or labour or both must be modelled indeed at the aggregate level it is difficult to provide a coherent account of how it is possible to have output above its equilibrium value since this would require labour and output in excess of their notional supplies violating barro and grossman s min condition that quantities be determined by the short side of the market an appealing line for addressing this last difficulty is to disaggregate markets an approach taken by hansen i970 tobin i972 and barro and grossman i976 ch 5 however because each market can be in either excess supply or demand a formal fixed price general equilibrium model appears to be intractable due to the resulting multiplicity of regimes and is not attempted by these authors in this paper these problems are overcome in a disaggregated model in which

consumption driven market emergence new market development is well theorized from a firm centered perspective but research has paid scant attention to the emergence of markets from consumption activity the exceptions conceptualize market emergence as a product of consumer struggle against prevailing market logics this study develops a model of consumption driven market emergence in harmony with existing market offerings using ethnographic methods and actor network theory the authors chronicle the emergence of a new market within the motorcycle industry that develops with neither active participation nor interference from mainstream industry players findings reveal a process of multiple translations wherein consumers mobilize human and nonhuman actors to co constitute products practices and infrastructures these drive the growth of interlinked communities of practice which ultimately are translated into a fully functioning market the study highlights the roles of distributed innovation and diffusion embedded entrepreneurship and market catalysts in processes of market change and development

global energy transitions and political systems abstract transitioning from one form of energy to another has led to social change in areas such as production methods quality of life and labor productivity in addition there is a relationship between this social change and the emergence of different types of political systems surprisingly there are not many studies on the relationship between energy transitions and changes in political systems the purpose of this paper is to demonstrate that the transition from one form of energy to another has historically determined the type of political system and that this causal relationship has evolved through the ages a three stage approach was used in this study to examine this relationship in the past and present and to predict coming changes in the future the main finding is that from the foraging period to the oil age energy has been a factor in determining political systems however with the expansion of energy trade between nations and the emergence of new technology options the situation has been reversed political systems have now become a determinant of energy transitions also even democratic countries have been unwilling to transition to new forms of energy preferring instead to maintain fossil fuel based energy systems

play at any cost how cosplayers produce and sustain their ludic communal consumption experiences communal consumption is often described as inherently playful with previous research mainly focusing on successful ludic communal experiences and largely disregarding its potential pitfalls moreover the marketer is usually seen as the primary facilitator of ludic experiences which has marginalized the role of the consumer this article explores how consumers produce and sustain ludic consumption community experiences in the face of growing instrumental costs it assumes a practice theory lens and is based on an ethnographic inquiry into cosplay which is a time and resource intensive form of pop culture masquerade and craft consumption prolonged engagement in the cosplay community leads to growing emotional material temporal and competence related costs which hinder playful experiences consumers practice modularization reinforcement and collaboration to overcome these costs and maintain the important ludic sensations that motivate communal engagements

is energy transition promoting the decoupling economic growth from emission growth evidence from the 186 countries abstract a more comprehensive understanding the effects of energy transition on the decoupling economic growth from carbon emission growth at global and national scale can serve to develop more effective approaches towards to economic growth without emission growth this paper combined decoupling index model and decomposition approach to identify decoupling state and uncover factors driving decoupling process in the world and 186 countries divided into three groups upper middle income umi lower middle income lmi and high income hi between 1990 and 2014 regarding to decoupling state world experienced weak decoupling 1990 2000 expansive negative decoupling and expansive coupling 2000 2011 and weak decoupling 2011 2014 hi initially realized the most desirable strong decoupling while decoupling state of umi and lmi were rather not ideal enough especially lmi changed violently and appeared no clear improving trend turning to decomposition results energy transition had positively contributed to decoupling process of hi while not in umi and lmi hi enjoyed better energy utilization efficiency absolutely offsetting negative impact caused by economic scale to decoupling process more importantly umi and lmi had great economic potential and will definitely emit tremendous carbon emission without taking appropriate measurements consequently umi and lmi shall take more responsibility to reduce carbon emission and actively accelerate the process of energy transition so as to achieve economic growth strongly decouple from carbon emission

selling sharing and everything in between the hybrid economies of collaborative networks recent consumer research has examined contexts where market based exchange gift giving sharing and other modes of exchange occur simultaneously and obey several intersecting logics but consumer research has not conceptualized these so called hybrid economic forms nor explained how these hybrids are shaped and sustained using ethnographic and netnographic data from the collaborative network of geocaching this study explains the emergence of hybrid economies performativity theory is mobilized to demonstrate that the hybrid status of these economies is constantly under threat of destabilization by the struggle between competing performativities of market and nonmarket modes of exchange despite latent tension between competing performativities the hybrid economy is sustained through consumer producer engagements in collaborative consumption and production the creation of zones of indeterminacy and the enactment of tournaments of value that dissipate controversies around hybrid transactions implications are drawn for consumer research on the interplay between market and nonmarket economies

the cleansing effect of recessions the authors investigate industry response to cyclical variations in demand production units that embody the newest process and product innovations are continuously being created and outdated units are being destroyed although outdated units are the most likely to turn unprofitable and be scrapped in a recession they can be insulated from the fall in demand by a reduction in creation the structure of adjustment costs plays a determinant role in the responsiveness of those two margins the calibrated model matches the relative volatilities of the observed manufacturing job creation and destruction series and their asymmetries over the cycle copyright 1994 by american economic association

real wage cyclicality in the eurozone before and during the great recession evidence from micro data we study the response of real wages to the business cycle in eight major eurozone countries before and during the great recession average real wages are found to be acyclical but this reflects in large part the effect of changes in the composition of the labour force related to unemployment variations over the cycle using longitudinal micro data from the echp and silc panels to control for composition effects we estimate the elasticities of real wage growth to unemployment increases between 0 6 and 1 over the period 1994 2011 composition effects have been particularly large since 2008 and they explain most of the stagnation or increase in the average wage observed in some countries from 2008 to 2011 in contrast at a constant labour force composition in terms of education and experience the figures indicate a significant decrease in average wages during the downturn particularly in countries most affected by the crisis overall there is no evidence of downward nominal wage rigidity during the great recession in most countries in our sample
