profit maximising goes global the race to the bottom we explore four decades of cyclical and long run dynamics in income distribution and economic activity for a panel of 13 oecd countries as measured by the wage share and output gap when modeled as predator prey dynamics economic activity in oecd countries is weakly profit led convergence to a long run equilibrium is relatively slow delaying the profit squeeze stage for many years our race to the bottom model suggests that the oecd countries have been engaged in undercutting each other s real unit labour costs an extension of the model shows that the long run equilibrium has been shifting south west towards a lower wage share it may even be that this race has the undesirable consequence of decreasing economic activity

civil unrest in north africa risks for natural gas supply abstract the uprising and military confrontation in libya that began in february 2011 has led to disruptions of gas supplies to europe an analysis of how europe has compensated for these missing gas volumes shows that this situation has not affected security of supply however this situation would change if the north african uprising were to spread to algeria since algeria is a much more important gas supplier to europe than is libya more severe consequences would be likely applying a natural gas infrastructure model we investigate the impact of supplier disruptions from both countries for a summer and winter period our analysis shows that disruptions in the low demand summer months could be compensated for mainly by lng imports into several european countries an investigation of a similar situation at the beginning of the winter shows that security of supply would be severely compromised and that disruptions to italian consumers would be unavoidable the analysis thereby highlights the importance of taking the political stability of supply countries into account when assessing the security of european gas imports

wage vs profit led growth the role of the distribution of wages in determining regime character the wage versus profit led distinction is a cornerstone of post keynesian growth theory however the existing theoretical literature focuses on the functional distribution of income and ignores the distribution of wages this paper shows how the distribution of wages affects whether an economy is wage or profit led since the distribution of wages impacts personal income distribution that explains why income inequality can also impact regime character increases in workers wage share always increase growth and capacity utilization regardless of the economy s character furthermore an increase in workers wage share can flip an economy from being profit led to wage led

natural resources curse or blessing are natural resources a curse or a blessing the empirical evidence suggests that either outcome is possible this paper surveys a variety of hypotheses and supporting evidence for why some countries benefit and others lose from the presence of natural resources these include that a resource bonanza induces appreciation of the real exchange rate deindustrialization and bad growth prospects and that these adverse effects are more severe in volatile countries with bad institutions and lack of rule of law corruption presidential democracies and underdeveloped financial systems another hypothesis is that a resource boom reinforces rent grabbing and civil conflict especially if institutions are bad induces corruption especially in nondemocratic countries and keeps in place bad policies finally resource rich developing economies seem unable to successfully convert their depleting exhaustible resources into other productive assets the survey also offers some welfare based fiscal rules for harnessing resource windfalls in developed and developing economies

union membership and employment dynamics a note we analyze union behavior in a model with membership dynamics and compare the labor market outcomes to static union models based on empirical findings we modify standard models and show that the well known result that static models overstate distortions caused by unions only holds in the special case of firm level wage setting if however the union is big enough to determine employment for the whole sector it rather depends on both the elasticity of labor demand and union s time preference whether static frameworks overrate or even underrate unions distortions jel code c61 j50 j51

output dynamics in real business cycles models the time series literature reports two stylized facts about output dynamics in the united states gnp growth is positively autocorrelated and gnp appears to have an important trend reverting component this paper investigates whether current real business cycle rbc models are consistent with these stylized facts many rbc models have weak internal propagation mechanisms and must rely on external sources of dynamics to replicate both facts models that incorporate labor adjustment costs are partially successful they endogenously generate positive autocorrelation in output growth but they need implausibly large transitory shocks to match the trend reverting component in output

price changes in the euro area and the united states some facts from individual consumer price data prices of goods and services do not adjust immediately in response to changing demand and supply conditions this paper characterizes the average frequency and size of price changes in the euro area and its member countries investigates the determinants of the probability of price changes and compares the evidence for the euro area with available u s results the facts documented in this paper are based on evidence from individual price data recorded at the store level in all euro area countries except ireland and greece that is in datasets covering austria belgium finland france germany italy luxembourg the netherlands portugal and spain which together account for around 97 percent of euro area gdp the data used are the monthly price records underlying the computation of national consumer price indices and harmonized consumer price indices these data cover a large number of products selected on the basis of extensive household budget surveys

a micro data approach to the identification of credit crunches this article presents a micro data approach to the identification of credit crunches using a survey among german firms which regularly queries the firms assessment of the current willingness of banks to extend credit we estimate the probability of a restrictive loan supply policy by time taking into account the creditworthiness of borrowers creditworthiness is approximated by firm specific factors e g the firms assessment of their current business situation and their business expectations after controlling for the return on the banks risk free investment alternative which is also likely to affect the supply of loans we derive a credit crunch indicator which measures that part of the shift in the loan supply that is neither explained by firm specific factors nor by the opportunity costs of providing risky loans

strategic eurasian natural gas market model for energy security and policy analysis formulation and application to south stream abstract the mathematical formulation of a strategic eurasian natural gas market model is presented the model represents horizontal oligopolistic relationships among producers bilateral market power between producer russia and transit ukraine countries detailed transport constraints and operation decisions over a 20 year time horizon to demonstrate the model s capabilities a financial and market analysis of the proposed south stream gas pipeline from russia via the black sea to south europe is summarized insights obtained include the following first expectations of high demand growth in europe and or transit risks do not justify the construction of the south stream pipeline because under all demand and ukraine transit interruption scenarios the net benefits to the south stream participants are negative the npv ranges from 1 9 billion bn to 7 4 bn second ukraine s perception of high transit market power vis a vis russia may trigger the construction of the otherwise unprofitable south stream project thus under ukraine s high transit market power scenario the npv of south stream ranges between 2 4 bn and 24 5 bn third we find that the south stream investment increases the efficiency of the european gas market under the following conditions i when gas demand in europe grows 2 per year up to 2030 ii when ukraine poses high transit market power or iii under a combination of severe transit risks through ukraine and low demand scenarios in europe it should be noted that the value of south stream to both its project sponsors and the market as a whole is much higher when ukraine exercises transit market power than under the high demand scenario therefore whether ukraine is likely to wield market power is crucial to the success of the south stream project because that is the only scenario in which the project yields both a positive expected npv to its sponsors and the highest value to the market as a whole

money new keynesian macroeconomics and the business cycle abstract we show in this paper that the typical modern business cycle cannot be reduced to the real business cycles archetype a monopolistic competition model with price adjustment costs affected by technological and monetary shocks better mimics the economic fluctuations in two countries with very different cyclical properties namely france and the united states in our model monetary shocks are necessary to reproduce the standard deviation of output the money output correlation the labour productivity worked hours relative standard deviation the labour productivity worked hours correlation and the mark up output correlation with two independent shocks one real more specifically defined than the solow residual and one nominal the model gives an answer to some empirical puzzles which were left unexplained by traditional rbc models

elusive persistence wage and price rigidities the new keynesian phillips curve and inflation dynamics abstract we review the main new keynesian inflation equations that have arisen as a result of aggregation from individual firms price rigidities we find that on the whole they cannot account for inflation persistence a key feature of the empirical dynamics of inflation and with important policy implications the only exceptions seem to be when indexation is allowed in price setting or when price stickiness is combined with wage rigidity and staggering

an empirical model of labor supply in a life cycle setting this paper formulates and estimates a structural intertemporal model of labor supply using theoretical characterizations derived from an economic model of lifetime behavior a two step empirical analysis yields estimates of intertemporal and uncompensated substitution effects which provide the information needed to predict the response of hours of work to life cycle wage growth and shifts in the lifetime wage path

hyperbolic discounting and the phillips curve using a standard dynamic general equilibrium model we show that the interaction of staggered nominal contracts with hyperbolic discounting leads to inflation having significant long run effects on real variables

separating the hawks from the doves evidence from continuous time laboratory games human players in our laboratory experiment received ow payos over 120 seconds each period from a standard hawk dove bimatrix game played in continuous time play converged closely to the symmetric mixed nash equilibrium under a one population matching protocol when the same players were matched in a two population protocol with the same bimatrix they showed clear movement towards an asymmetric and very inequitable pure nash equilibrium of the game these ndings support distinctive predictions of evolutionary game theory

political culture and discrimination in contests abstract many economic and political decisions are the outcome of strategic contests for a given prize the nature of such contests can be determined by a designer who is driven by political considerations with a specific political culture the main objective of this study is to analyze the effect of political culture and of valuation asymmetry on discrimination between the contestants the weights assigned to the public well being and the contestants efforts represent the political culture while discrimination is an endogenous variable that characterizes the mechanism allocating the prize we consider situations under which the optimal bias of the designer is in favor of the contestant with the larger or smaller prize valuation and examine the effect of changes in the political culture and in valuation asymmetry on the designer s preferred discrimination between the contestants focusing on the two most widely studied types of contest success functions deterministic all pay auctions and logit csfs we show that an all pay auction is always the preferred csf from the point of view of the contest designer this result provides a new political economic micro foundation to some of the most commonly used models in the contest literature

a complementarity model for the european natural gas market abstract in this paper we present a detailed and comprehensive complementarity model for computing market equilibrium values in the european natural gas system market players include producers and their marketing arms which we call traders pipeline and storage operators marketers lng liquefiers regasifiers tankers and three end use consumption sectors the economic behavior of producers traders pipeline and storage operators liquefiers and regasifiers is modeled via optimization problems whose karush kuhn tucker kkt optimality conditions in combination with market clearing conditions form the complementarity system the lng tankers marketers and consumption sectors are modeled implicitly via appropriate cost functions aggregate demand curves and ex post calculations respectively the model is run on several case studies that highlight its capabilities including a simulation of a disruption of russian supplies via ukraine

estimating the top tail of the wealth distribution abstract this paper uses the household finance and consumption survey to construct new estimates of top wealth shares in germany france spain italy belgium austria finland and the netherlands

income inequality in the united states 1913 1998 this paper presents new homogeneous series on top shares of income and wages from 1913 to 1998 in the united states using individual tax returns data top income and wages shares display a u shaped pattern over the century our series suggest that the large shocks that capital owners experienced during the great depression and world war ii have had a permanent effect on top capital incomes we argue that steep progressive income and estate taxation may have prevented large fortunes from fully recovering from these shocks top wage shares were flat before world war ii dropped precipitously during the war and did not start to recover before the late 1960s but are now higher than before world war ii as a result the working rich have replaced the rentiers at the top of the income distribution

nominal rigidity and monetary uncertainty abstract a stochastic macromodel with dynamically optimising wage setting households is used to examine the effect on current macroeconomic variables of an anticipated increase in variability of the money stock there is a nominal rigidity in the form of a money wage set one period in advance in whose absence monetary uncertainty has no effect on current variables we show that for plausible parameterisations monetary uncertainty combined with nominal rigidity raises the nominal interest rate depressing aggregate demand and hence current price and output it also causes the wage to be set higher increasing the natural rate of unemployment

real and nominal propagation of nominal shocks the role of real and nominal propagation mechanisms in generating persistent real effects of nominal shocks is analysed analytically in a fully specified intertemporal general equilibrium model while neither a real propagation mechanism capital acccumulation with one period nominal contracts nor nominal propagation staggered nominal contracts in the absence of any real propagation can generate plausible impulse responses with strong persistence it is shown that the two mechanisms interact so as to strengthen persistence possibly unit roots and generate more plausible impulse responses

endogenous business cycle propagation and the persistence problem the role of labor market frictions contrasting sharply with a recent trend in dsge modeling we propose a business cycle model where frictions and shocks are chosen with parsimony the model emphasizes a few labor market frictions and shocks to monetary policy and technology the model estimated from u s quarterly postwar data accounts well for important differences in the serial correlation of the growth rates of aggregate quantities the size of aggregate fluctuations and key comovements including the correlation between hours and labor productivity despite its simplicity the model offers an answer to the persistence problem chari et al 2000 that does not rely on multiple frictions and adjustment lags or ad hoc backward looking components we conclude modern dsge models need not embed large batteries of frictions and shocks to account for the salient features of postwar business cycles

volatility transmission in emerging european foreign exchange markets abstract this paper studies the dynamics of volatility transmission between central european ce currencies and the eur usd foreign exchange using model free estimates of daily exchange rate volatility based on intraday data we formulate a flexible yet parsimonious parametric model in which the daily realized volatility of a given exchange rate depends both on its own lags as well as on the lagged realized volatilities of the other exchange rates we find evidence of statistically significant intra regional volatility spillovers among the ce foreign exchange markets with the exception of the czech and prior to the recent turbulent economic events polish currencies we find no significant spillovers running from the eur usd to the ce foreign exchange markets to measure the overall magnitude and evolution of volatility transmission over time we construct a dynamic version of the diebold yilmaz volatility spillover index and show that volatility spillovers tend to increase in periods characterized by market uncertainty

inventories sticky prices and the persistence of output and inflation post war business cycle fluctuations of output and inflation are remarkably persistent many recent sticky price models however grossly underpredict this persistence we assess whether adding inventories to a standard sticky price model raises the persistence of output and inflation for this addition we consider a shopping cost model in the model consumers find shopping activities costly and the cost of shopping depends on the stock of goods available in this context producers manage inventories to smooth production and to affect the cost of shopping we find that the shopping cost model generates a persistence for output and inflation that matches the persistence observed in the post 1985 us data

european union gas market development abstract the recently announced energy union by the european commission is the most recent step in a series of developments aiming at integrating the european union s eu gas markets in order to increase social welfare and security of gas supply based on simulations with a spatial partial equilibrium model we analyze the changes in consumption prices and social welfare up to 2022 induced by the infrastructure expansions planned for this period for the current market as well as for three hypothetical scenarios a halt of russian gas deliveries to the eu during the winter period ru a simultaneous doubling of available lng lng and for brexit in which the united kingdom market is isolated from the eu in the case of the current market the new infrastructure leads to a slight decrease of wholesale prices moreover the potential of suppliers to exert market power decreases significantly particularly in the baltic states and finland which are the most exposed countries today and consumer surplus increases by 17 4 in the eu in the ru scenario consumer surplus decreases across europe with the largest losses occurring in the baltic states as well as in finland poland and romania in the lng scenario the gains in consumer surplus are primarily found in western europe however the planned infrastructure expansions distribute the gains and losses in consumer surplus more evenly over all eu member states with the exception of romania in the brexit scenario consumer surplus decreases by up to 5 1 in the united kingdom 19 2 in ireland and 3 6 in the other eu countries our results allow us to distinguish three categories of projects i change in gas availability leading to a general increase or decrease of social welfare all over the eu the only project increasing social welfare in all scenarios in most countries is the trans anatolian gas pipeline tanap ii existing gas sources made available to additional countries this leads to an increase of social welfare in the newly connected countries while social welfare drops slightly everywhere else iii projects with a marginal effect on the market most notably the recently announced turkish stream falls into this category our results indicate that if all proposed infrastructure projects are realized the eu s single market will become a reality in 2019 when finland is interconnected to the eu markets however we also find that social welfare can only be increased significantly for the eu as a whole if new gas sources become accessible at the same time efficiency gains albeit decreasing social welfare help to improve the situation of consumers and decrease the dependency of the eu as a whole on external suppliers

persistency in sticky price models abstract nominal rigidities imply that nominal shocks have an impact effect which may be propagated by standard mechanisms however the nominal adjustment process may in itself be a propagation mechanism causing persistent effects of nominal shocks this may be caused by inertia in nominal wage and price adjustment arising due to input output networks or multiperiod nominal contracting as captured in models with staggered price wage decisions it has recently been contested whether staggering can account for persistency of any quantitative importance this paper reviews the theory and empirical evidence on this issue and it is concluded that staggering may be a quantitative important propagation mechanism

functional income distribution and aggregate demand in the euro area an increase in the wage share has contradictory effects on the subaggregates of aggregate demand private consumption expenditures ought to increase because wage incomes typically are associated with higher consumption propensities than capital incomes investment expenditures ought to be negatively affected because investment will positively depend on profits net exports will be negatively affected because an increase in the wage share corresponds to an increase in unit labour costs and thus a loss in competitiveness therefore theoretically aggregate demand can be either wage led or profit led depending on how these effects add up the results will crucially depend on how open the economy is internationally the paper estimates a post kaleckian macro model incorporating these effects for the euro area and finds that the euro area is presently in a wage led demand regime implications for wage policies are discussed

natural gas corridors between the eu and its main suppliers simulation results with the dynamic gastale model abstract growth in gas demand poses a challenge for european energy consumers and other gas importing countries in terms of an increasing dependency on gas imports and consequently also supply security this paper focuses on interactions among demand supply and investments in natural gas corridors namely pipeline transport lng and storage facilities affecting the european natural gas market over the period 2005 2030 a number of policy scenarios including a business as usual bau scenario are formulated to study the impact of demand uncertainty and delays in investment on the gas transport infrastructure required in the long run in europe the analyses indicate that substantial investments in gas transport corridors are needed to accommodate imports and seasonal demand variations analysis of scenarios of supply interruption in the form of suddenly reduced import capacity for particular pipeline routes indicates that portions of europe could experience price increases of up to 100 in the case of a year long interruption to accommodate import needs and to mitigate possible disruptions pipeline connections running from east to west need to be given special priority

flattening of the phillips curve under low trend inflation abstract this study indicates why the phillips curve is flattened in an environment of low trend inflation the key is the curvature of the demand curve

top incomes in the long run of history a recent literature has constructed top income shares time series over the long run for more than twenty countries using income tax statistics top incomes represent a small share of the population but a very significant share of total income and total taxes paid hence aggregate economic growth per capita and gini inequality indexes are sensitive to excluding or including top incomes we discuss the estimation methods and issues that arise when constructing top income share series including income definition and comparability over time and across countries tax avoidance and tax evasion we provide a summary of the key empirical findings most countries experience a dramatic drop in top income shares in the first part of the twentieth century in general due to shocks to top capital incomes during the wars and depression shocks top income shares do not recover in the immediate postwar decades however over the last thirty years top income shares have increased substantially in english speaking countries and in india and china but not in continental european countries or japan this increase is due in part to an unprecedented surge in top wage incomes as a result wage income comprises a larger fraction of top incomes than in the past finally we discuss the theoretical and empirical models that have been proposed to account for the facts and the main questions that remain open

monopolistic competition and the effects of aggregate demand how important is monopolistic competition to an understanding of the effects of aggregate demand on output we ask the question at three levels can monopolistic competition by itself explain why aggregate demand movements affect output can it together with other imperfections generate effects of aggregate demand in a way that perfect competition cannot if so can it give an accurate account of the response of the economy to aggregate demand movements the answers are no yes and yes

multiplicity of equilibria in conjectural variations models of natural gas markets abstract spatial partial equilibrium models incorporating conjectural variations are widely used to analyze the development of oligopolistic multi agent markets such as international energy and raw material markets although this model type can produce multiple equilibria under commonly used assumptions to the best of our knowledge the consequences for the interpretation of the model results have not yet been explored in detail to this end we derive a linear complementarity model for the gas market and discuss under which assumptions on the model structure a component of the solution is unique in particular we find that the gas flow between a trader and a consumer is unique whenever the trader is modeled to exert market power in the consumer s market we demonstrate our findings by computing the extreme points of the polyhedral solution space and show that erroneous conclusions could be drawn whenever only one arbitrary point in the solution space is picked for interpretation furthermore we discuss whether economically meaningful parameter value changes exist which would enforce uniqueness in all components of the solution

europe s great depression coordination failure after the first world war in this paper i survey and reinterpret the extensive literature on europe s great depression i argue that europe could not exploit its vast economic potential after 1918 because the war had not yet come to an end indeed it did not end before 1945 both domestic and international institutions suffered from a lack of reciprocal trust and commitment which can be clearly illustrated in the realm of monetary policy but affected many other areas of policy making such as energy or migration policies these institutions in turn affected expectations and thereby the extent to which for example expansionary policies could be effective

wage led growth in the eu15 member states the effects of income distribution on growth investment trade balance and inflation this paper estimates a multi country demand led growth model for eu15 countries a decrease in the share of wages in national income in isolation leads to lower growth in finland france germany greece italy luxembourg netherlands portugal spain sweden and the united kingdom whereas it stimulates growth in austria belgium denmark and ireland however a simultaneous decline in the wage share leads to an overall decline in eu15 gdp hence eu15 as a whole is a wage led economy furthermore austria and ireland also experience negative effects on growth when they decrease their wage share along with their trading partners the results indicate that a decline in the wage share has had significant negative effects on growth in the eu15 countries and supports the case of wage coordination we present different wage led recovery scenarios taking into account further effects of a change in the wage share on prices nominal unit labour costs investment and net exports

contract length heterogeneity and the persistence of monetary shocks in a dynamic generalized taylor economy we develop the generalized taylor economy gte in which there are many sectors with overlapping contracts of different lengths in economies with the same average contract length monetary shocks will be more persistent when longer contracts are present using the bils klenow distribution of contract lengths we find that the corresponding gte tracks the u s data well when we choose a gte with the same distribution of completed contract lengths as the calvo the economies behave in a similar manner

a further contribution towards explaining why disinflation through currency pegging may cause a boom abstract we revisit the question of why exchange rate based erb disinflation is often expansionary we use an analytical dge model in discrete time with staggered wages if the policy is unanticipated and if the currency is pegged at the level it would have reached under unchanged policies then a boom occurs for preannounced erb disinflation our model also predicts a boom the explanation for both is that when wages are staggered wage setters have to be forward looking anticipating lower future inflation they reduce wages before the change in the exchange rate causing a favourable supply side effect on output

generalised taylor and generalised calvo price and wage setting micro evidence with macro implications the generalised calvo and the generalised taylor models of price and wage setting are unlike the standard calvo and taylor counterparts exactly consistent with the distribution of durations observed in the data using price and wage micro data from a major euro area economy france we develop calibrated versions of these models we assess the consequences for monetary policy transmission by embedding these calibrated models in a standard dynamic stochastic general equilibrium model the generalised taylor model is found to help rationalise the hump shaped and persistent response of inflation without resorting to the counterfactual assumption of systematic wage and price indexation

personal income inequality and aggregate demand this paper presents a theoretical and empirical investigation of how changes in the size distribution of income can aect aggregate demand and the demand regime of an economy after presenting empirical evidence for the us economy that the propensity to save increases signicantly from the bottom to the top quintile of wage earners we demonstrate that more equal distributions always lead to higher output in the traditional neo kaleckian macroeconomic model we also present conditions under which a reduction of income inequality among workers turns demand more wage led this view is supported by the results of an econometric study for the united states 1967 2010 which show that the rise after 1980 in income inequality has made the us economy more prot led

price wage staggering and persistence a unifying framework in this paper we provide a general unified framework to clarify the issue of persistence of real effects of money shocks in staggered wage price models we mainly aim to i highlight which features of the underlying economy and particularly of the labour market are crucial for generating output persistence ii analyse the differences between price and wage staggering copyright blackwell publishing ltd 2003

pay for politicians and candidate selection an empirical analysis abstract a growing theoretical literature on the effect of politicians salaries on the average level of skills of political candidates yields ambiguous predictions in this paper we estimate the effect of pay for politicians on the level of education of parliamentary candidates we take advantage of an exceptional reform where the salaries of finnish mps were increased by 35 in the year 2000 intended to make the pay for parliamentarians more competitive a difference in differences analysis using candidates in municipal elections as a control group suggests that the higher salary increased the fraction of candidates with higher education among female candidates while we find no significant effect for male candidates

output persistence from monetary shocks with staggered prices or wages under a taylor rule we analytically examine output persistence from monetary shocks in a dsge model with staggered prices or wages under a taylor rule surprisingly while taylor style staggering never yields persistence calvo style staggering of wages does generate persistence under decreasing returns to labour c 2009 elsevier b v all rights reserved

optimal monetary policy in the generalized taylor economy in this paper we use the generalized taylor economy gte framework to examine the optimal choice of inflation index in this otherwise standard dynamic stochastic general equilibrium dsge model there can be many sectors each with a different contract length in the gte framework with an empirically relevant contract structure a simple rule under which the interest rate responds to economy wide inflation gives a welfare outcome nearly identical to the optimal policy this finding suggests that it may not be necessary for a well designed monetary policy to respond to sector specific inflations

global inequality dynamics new findings from wid world this paper presents new findings on global inequality dynamics from the world wealth and income database wid world with particular emphasis on the contrast between the trends observed in the united states china france and the united kingdom we observe rising top income and wealth shares in nearly all countries in recent decades but the magnitude of the increase varies substantially thereby suggesting that different country specific policies and institutions matter considerably long run wealth inequality dynamics appear to be highly unstable we stress the need for more democratic transparency on income and wealth dynamics and better access to administrative and financial data

increasing returns to scale and the long run phillips curve abstract a growing body of empirical evidence shows that there exists a long run positive trade off between inflation and real macroeconomic activity within a new keynesian framework we examine how increasing returns generate a positive long run relation between inflation and output

unemployment and the real wage the economic basis for contesting political ideologies using the keynesian theory of effective demand this paper demonstrates how particular models such as that of cooperative capitalism enunciated by the left keynesian social democrats the marxian model of profit squeeze emphasizing distributive conflict and even the conservative model relying on supply side stimulus fit in as particular variants of a more general theoretical scheme through a reconstruction of the familiar is schedule the argument is weaved around the theme of the relations between unemployment and real wage in the context of both a closed and an open economy to explain the common macroeconomic basis of contesting ideologies copyright 1990 by oxford university press

financialisation and the slowdown of accumulation over the past decades financial investment of non financial businesses has been rising and accumulation of capital goods has been declining the first part of the paper offers a novel theory to explain this phenomenon financialization the shareholder revolution and the development of a market for corporate control have shifted power to shareholders and thus changed management priorities leading to a reduction in the desired growth rate in the second part the link between accumulation and financialization is tested econometrically by means of a time series analysis of aggregate business investment for usa uk france and germany extensive test of robustness are performed for the first three countries evidence that confirms the negative effect of financialization on accumulation is found author s abstract

optimising agents staggered wages and persistence in the real effects of money shocks in this paper we incorporate taylor s 1979 staggered wage setting into an optimising dynamic general equilibrium framework to study whether staggered wages could induce a high degree of persistence in the real effects of money shocks we conclude that high persistence is an unlikely outcome sensible values of the microeconomic parameters and or a moderate rate of underlying inflation imply a low degree of persistence furthermore once explicit microfoundations are taken into account we show that i the model is highly non linear ii the inertia of the system is inversely related to the level of average inflation

endogenous capacity utilization and macroeconomic persistence abstract this paper presents a monetary dynamic general equilibrium model featuring a strong internal propagation mechanism limited short run factor substitutability and idiosyncratic demand uncertainty play a prominent role in the results firms are ex post heterogeneous and a well defined distribution of capacity utilization rates characterizes the equilibrium of the model the economy responds gradually to aggregate shocks since firms with excess capacity can raise production without experiencing large increases in their marginal costs the modeling framework presented in this paper offers a plausible microeconomic interpretation for reduced form mark up shocks typically considered in the new keynesian literature

wealth inequality in the united states since 1913 evidence from capitalized income tax data this paper combines income tax returns with flow of funds data to estimate the distribution of household wealth in the united states since 1913 we estimate wealth by capitalizing the incomes reported by individual taxpayers accounting for assets that do not generate taxable income we successfully test our capitalization method in three micro datasets where we can observe both income and wealth the survey of consumer finance linked estate and income tax returns and foundations tax records wealth concentration has followed a u shaped evolution over the last 100 years it was high in the beginning of the twentieth century fell from 1929 to 1978 and has continuously increased since then the rise of wealth inequality is almost entirely due to the rise of the top 0 1 wealth share from 7 in 1979 to 22 in 2012 a level almost as high as in 1929 the bottom 90 wealth share rst increased up to the mid 1980s and then steadily declined the increase in wealth concentration is due to the surge of top incomes combined with an increase in saving rate inequality top wealth holders are younger today than in the 1960s and earn a higher fraction of total labor income in the economy we explain how our ndings can be reconciled with survey of consumer finances and estate tax data

reference norms staggered wages and wage leadership theoretical implications and empirical evidence this article presents an extension of the taylor model with staggered wages in which wage setting is also influenced by reference norms we show that reference norms can considerably increase the persistence of inflation but that the size of this effect depends on the exact definition e g external vs internal symmetric vs asymmetric norms using data on collectively bargained wages in austria from 1980 to 2006 we show that wage setting is strongly influenced by reference norms that external norms seem to matter more than internal norms and that there is a clear indication for the existence of wage leadership asymmetric norms

stabilisation policy rational expectations and price level versus inflation targeting a survey we survey literature comparing inflation targeting it and price level targeting pt as macroeconomic stabilisation policies our focus is on new keynesian models and areas that have seen significant developments since ambler s 2009 price level targeting and stabilisation policy a survey journal of economic surveys 23 5 974 997 survey optimal monetary policy the zero lower bound financial frictions and transition costs of adopting a pt regime ambler s conclusion that pt improves social welfare in new keynesian models is fairly robust but we note an interesting split in the literature pt consistently outperforms it in models where policymakers commit to simple taylor type rules but results in favour of pt when policymakers minimise loss functions are overturned with small deviations from the baseline model since the beneficial effects of pt appear to hang on the joint assumption that agents are rational and the economy new keynesian we discuss survey and experimental evidence on rational expectations and the applied macro literature on the empirical performance of new keynesian models overall the evidence is not clear cut but we note that new keynesian models can pass formal statistical tests against macro data and that models with rational expectations outperform those with behavioural expectations i e heuristics in direct statistical tests we therefore argue that policymakers should continue to pay attention to pt

identifying the influences of nominal and real rigidities in aggregate price setting behavior we formulate a generalized price setting framework that incorporates staggered contracts of multiple durations and that enables us to directly identify the influences of nominal vs real rigidities we estimate this framework using macroeconomic data for germany 1975 1998 and for the u s 1983 2003 in each case we find that the data are well characterized by nominal contracts with an average duration of about two to three quarters we also find that new contracts exhibit very low sensitivity to marginal cost corresponding to a relatively high degree of real rigidity finally our results indicate that backward looking price setting behavior such as indexation to lagged inflation is not needed in explaining the aggregate data at least in an environment with a stable monetary policy regime and a transparent and credible inflation objective

phillips curves and unemployment dynamics a critique and a holistic perspective the conventional wisdom that inflation and unemployment are unrelated in the long run implies that these phenomena can be analysed by separate branches of economics the macro literature tries to explain inflation dynamics and estimates the nairu the labour macro literature tries to explain unemployment dynamics and determine the real economic factors that drive the natural rate of unemployment we show that the orthodox view that the new keynesian phillips curve is vertical in the long run and that it cannot generate substantial inflation persistence relies on the implausible assumption of a zero interest rate in the light of these results we argue that a holistic framework is needed to jointly explain the evolution of inflation and unemployment

on endogenously staggered prices taylor s model of staggered contracts is an influential explanation for nominal inertia and the persistent real effects of nominal shocks however in standard imperfect competition models if agents are allowed to choose the timing of pricing decisions they will typically choose to synchronize this paper provides a simple model of imperfect competition which produces stable staggering our argument relies on strategic interaction at two levels between firms within an industries and across industries and produces a continuum of staggered price equilibria these equilibria are strict and hence stable under a simple adaptive learning process an enduring problem for business cycle theory is an explanation for the persistent effects of nominal shocks explaining persistence is particularly problematic for theories based on nominal shocks as opposed to real shocks this is because rational expectations implies that nominal shocks themselves cannot be serially correlated since nominal shocks are the deviation of realized nominal magnitudes from expected values in two important papers taylor 1979 1980 provided an argument as to why a nominal shock can have persistent effects taylor s argument required two important assumptions first he assumed that firms could adjust prices only in alternate periods an assumption which may be justified by menu or information costs taylor s second assumption was that price setting was staggered half the firms were constrained to adjust prices in odd periods while the other half were allowed to adjust prices in even periods these two assumptions combined to provide dramatic results on nominal inertia the adjustment of prices to a nominal shock is slow and hence output effects are long lasting taylor s results on persistence arise due to strategic complementarity between price setting decisions this implies that each firm s optimal price is an increasing function of the aggregate price level if a shock arrives in an even period firms in the even cohort will not adjust fully to the nominal shock since firms in the odd cohort have fixed prices in the current period furthermore with rational expectations the even cohort also takes into account the fact that its own failure to adjust fully will also make for partial adjustment in future periods this elegant story has made taylor s model possibly the most influential of new keynesian models by providing a dynamic setting within which small nominal rigidities may result in persistent nominal inertia

central asian gas in eurasian power game abstract following the dissolution of the soviet union various gas pipeline projects have been proposed to diversify transit routes and export markets of the landlocked central asian states to evaluate the pipeline project s impact on the players bargaining power i apply the cooperate game theory to a quantitative model of the eurasian gas trade and quantify the bargaining power structure via the shapley value due to ample production capacities in central asia i observe little strategic interaction between the west and china thus demand competition with china is not necessarily a disadvantage for the west and the turkmenistan china pipeline does not affect the impact of the westbound projects aiming europe and turkey for turkmenistan i e the main supplier in the region a link via the caspian sea to turkey is the most beneficial westbound option although the projects carrying gas from azerbaijan and turkmenistan to europe enjoy the european commission s political support they yield marginal benefits to the european consumers thanks to its transit position turkey collects a large share of the benefits in the east west gas trade
