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

the phillips curve macroeconomic policy and the welfare of canadians a review of the two competing paradigms explaining inflation and unemployment fluctuations singles out the keynesian phillips curve as the clear empirical winner over its classic competitors reestimation of the canadian phillips curve for 1957 90 identifies a sharp structural shift toward a high degree of unemployment hysteresis after 1972 the recent attempt of macropolicy to flatten the aggregate demand curve and limit supply side shock accommodation which aims at lower and more stable inflation is then shown to make unemployment higher and more unstable on average to an extent that is an increasing function of the degree of hysteresis understanding and reducing hysteresis and developing a consensus based incomes policy that has a chance of alleviating the dismal trade off should therefore to top research and policy priorities

a theory of voting equilibria a voting equilibrium arises when the voters in an electorate acting in accordance with both their preferences for the candidates and their perceptions of the relative chances of various pairs of candidates being in contention for victory generate an election result that justifies their perceptions voting equilibria always exist and the set of equilibria can vary substantially with the choice of voting system we compare equilibria under the plurality rule approval voting and the borda system we consider a candidate positioning game and find that the plurality rule imposes little restriction on the position of the winning candidate in three candidate races while approval voting leads to a winner positioned at the median of the voter distribution we contrast campaign activities intended to influence voter preferences with activities meant to influence only perceptions of candidate viability

the changing relationship between aggregate price and output the british experience over the past two and a half decades great britain has exhibited the most noticeable increase in inflation variability among the ten major noncommunist industrialized countries in addition there has been an apparent worsening in the output inflation tradeoff this paper attempts to identify and empirically assess possible causes of the deterioration in the british output inflation tradeoff in the context of a new classical type model supply side shocks can cause an increase in the inflation rate and a decrease in real output and it is estimatedthat such shocks interacted with inflation variability to reduce real output roughly 3 3 percent between the period 1957 1968 and the period 1969 1980 also contributing to the deterioration in the output inflation tradeoff it is estimated that the decline in the natural rate of real output due to inflation variability as hypothesized by milton friedman amounted to about 2 3 to 2 5 percent between these two subperiods this abstract was borrowed from another version of this item

strategic voting in the 1996 japanese general election japan s new electoral system may or may not be good for japanese democracy but it is almost ideally designed for the study of strategic voting no other existing electoral system provides political scientists with data on such neatly separated but simultaneous single member districts smd and proportional representation pr votes using candidate level aggregate data i find strong evidence for strategic voting candidates with a good chance of winning receive more smd than pr votes and those with little chance of winning receive more pr votes strategic voting explains not only the basic pattern but also several exceptions to the rule in addition i find that a realistic but relatively inaccurate ex ante prediction of a candidate s probability of victory produces a superior explanatory model than does a perfect ex post prediction calculated from the final electoral results these results support the hypothesis that voters base their strategic voting calculations on simple cues available to them befo

on the neutrality of fiscal policy abstract the paper explores the relationships between fiscal policy and real economic activity and prices for the six largest industrialized economies fiscal policy variables are shown to be consistent and rational functions of the behaviour of the economy it is also confirmed that fiscal policy seems to have a consistent impact on subsequent real economic activity and prices when multivariate time series analysis is used to breakdown overall fiscal policy into anticipated and unanticipated components the anticipated components are shown generally to have just as much forecasting ability for subsequently realized economic variables as the unanticipated components this does not appear to be consistent with the implications of pure rational expectations models

an examination of aggregate price uncertainty in four countries and someimplications for real output this stu dy constructs measures of aggregate price uncertainty for four countries canada west germany great britain and the united states and examines the relationship across countries and through time between the inflation rate inflation variability and measures of price uncertainty the results suggest that the higher and more variable inflation of the 1970s increased uncertainty about the aggregate price level in canada great britain and the united states but not west ge rmany and there was a significant negative output effect of aggregate price uncertainty for canada and the united kingdom but not for the united states or west germany copyright 1987 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

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

assessing the variability of inflation although there has been much argument over the impact of variable inflation rates upon economic performance there has been surprisingly little attempt to define the term variability of inflation carefully or to test proposed hypotheses connecting variability and the level of inflation precise definitions are given in the paper and a model is constructed showing that the level variability hypothesis may be formulated in terms of the presence of heteroscedasticity in a regression model this theoretical model is used to criticize existing studies while an empirical study with australian data illustrates the application of the approach

money and the dispersion of relative prices a price dispersion equation is tested with data from the german hyperinflation the equation is derived from a version of lucas s and barro s partial information localized market models in this extension different excess demand elasticities across commodities imply a testable dispersion equation in which the explanatory variable is the magnitude of the unperceived money growth in order to test this hypothesis a price dispersion series is constructed and a measure of the unperceived part of money growth is estimated the model receives support from the empirical analysis although it is evident that unincluded variables have important effects on price dispersion

a statistical model for multiparty electoral data we propose an internally consistent and comprehensive statistical model for analyzing multiparty district level aggregate election data this model can be used to explain or predict how the geographic distribution of electoral results depends upon economic conditions neighborhood ethnic compositions campaign spending and other features of the election campaign or characteristics of the aggregate areas we also provide several new graphical representations for help in data exploration model evaluation and substantive interpretation although the model applies more generally we use it to help resolve an important controversy over the size of and trend in the electoral advantage of incumbency in great britain contrary to previous analyses which are all based on measures now known to be biased we demonstrate that the incumbency advantage is small but politically meaningful we also find that it differs substantially across the parties about half a percent for the conservatives 1 for the labor party and 3 for the liberal party and its successors also contrary to previous research we show that these effects have not grown in recent years finally we are able to estimate from which party each party s incumbency advantage is predominantly drawn

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

low inflation targeting and long run unemployment the model of akerlof dickens and perry 2000 adp predicts that low inflation may cause unemployment to persist at high levels when applied to u s data their results strongly rejected the conventional nairu model we apply the adp model to swedish data the fact that our swedish data also reject the nairu model has a number of interesting implications for the swedish economy and potentially for other european countries as well the results indicate that raising the swedish inflation target from 2 to 4 percent would bring longrun unemployment down by several percentage points the possibility of adp type long run phillips curves also across the euro countries may raise some concern about the emu project while detailed studies on other countries are needed there is nothing to suggest that these non vertical phillips curves would not differ considerably across the euro countries any single inflation level targeted by the ecb would then generate excess unemployment in individual member states

another perspective on the effects of inflation uncertainty this paper examines the effects of inflation uncertainty on real economic activity by utilizing a flexible dynamic multivariate framework that accommodates possible interaction between the conditional means and variances the empirical model is based on a familiar identified vector autoregressive framework modified to accommodate multivariate generalized autoregressive conditional heteroskedasticity our empirical model is preferred to the baseline var by likelihood based information criteria and it retains the important dynamics of the underlying var we find that an average shock to inflation uncertainty has tended to reduce output growth over three months by about 22 basis points

inflation and labor market adjustment the implications of downward nominal and ex ante real wage rigidity and of wage contracting for the dispersion of relative wage changes in the presence of price inflation are examined rigidity implies that unexpected inflation will raise the variability of relative wage changes contracting implies unexpected inflation reduces variability using data on manufacturing industries for 1955 81 and on private nonfarm industries for1965 81 these hypotheses are studied the dispersion in relative wage cnanges is reduced by greater price inflation most of the reduction is a response to unexpected inflation expected inflation has little impact on dispersion these findings hold for subperiods within the sample and are robust to different choices of measures of price expectations including those of the livingston survey the survey research center household data and arma forecasts they stand in striking contrast to the commonly accepted result that price inflation is associated with greater dispersion of relative price changes they suggest that inflation reduces the ability of relative wages to signal disequilibria among labor markets this abstract was borrowed from another version of this item

explaining the fame of friedman s presidential address it is noted that although in fact it lacks the revolutionary content commonly ascribed to it friedman s presidential address to the american economic association is very highly regarded as an original and formative contribution it is argued that close attention to the literature shows that it was not initially seen as original and only after an interval of five years did the idea of its revolutionary status retrospectively but suddenly become widely accepted the explanation of this change of view is considered four explanations are suggested one involving terminological confusion one involving a change in theoretical priorities and two involving debates of the 1970s which although they did not in fact do so appeared to build on friedman s presentation and by this appearance gave it an undeserved stature

redistributing income under proportional representation although majoritarian decision rules are the norm in legislatures relatively few democracies use simple majority rule at the electoral stage adopting instead some form of multiparty proportional representation moreover aggregate data suggest that average income tax rates are higher and distributions of posttax income flatter in countries with proportional representation than in those with majority rule while there are other differences between these countries this paper explores how variations in the political system per se influence equilibrium redistributive tax rates and income distributions a three party proportional representation model is developed in which taxes are determined through legislative bargaining among successful electoral parties and the economic decision for individuals is occupational choice political economic equilibria for this model and for a two party winner take all majoritarian system are derived and compared

atheoretical macroeconometrics a critique abstract the spurious nature of the restrictions used to identify many macroeconometric models has led some researchers to advocate a style of econometric inquiry that is less dependent on prior theoretical restrictions of the sort that were central to the approach of the cowles commission this development which we call atheoretical macroeconometrics is summarized and evaluated in the current paper it is contrasted with an updated version of the cowles commission approach we conclude that while some of the exercises of atheoretical macroeconometrics are valid those that have attracted the most attention and appear the most innovative exogeneity testing impulse response analysis and policy analysis using estimated vector autoregressions are based on incorrect analysis

interaction effects in mixed member electoral systems theory and evidence from germany japan and italy the past decade has witnessed a surprising growth in the popularity of mixed member electoral systems under these systems voters choose representatives simultaneously under both proportional representation pr and single member district plurality smdp rules it is widely accepted that smdp rules tend to winnow competition down toward two large parties and evidence from mixed systems suggests that this duvergerian gravity reduces the number of parties surviving smdp competition under mixed systems as well nevertheless we argue simultaneous balloting under pr rules softens this winnowing effect operating as a centrifugal force that prevents duvergerian gravity from reducing competition to the degree it does under pure smdp systems thus these newsystems produce effects unanticipated by their designers to test for the presence of this centrifugal force we examine elite level electoral strategies in germany japan and italy and compare district level smdp election results from pure systems w

duverger s law and the meaning of canadian exceptionalism duverger s law is an unusually simple and specific elaboration on exactly how political institutions matter it proposes that plurality rule elections result in two party competition canada is commonly thought to violate the law at the national level but to match its predictions at the district level and thus not to constitute a genuine counterexample in fact analysis of a vast data set of canadian election returns reveals that these elections are multicandidate events district by district year after year an explanation for this multipartyism may lie in the complicating factor of federalism because canadian provinces often feature strikingly different national and provincial party systems generally the canadian case illustrates that theories relating party systems to electoral law but not to other institutions are unrealistically parsimonious

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

a model of the political economy of the united states we develop and test a model of joint determination of economic growth and national election results in the united states the formal model which combines developments in the rational choice analysis of the behavior of economic agents and voters leads to a system of equations in which the dependent variables are the growth rate and the vote shares in presidential and congressional elections our estimates support the theoretical claims that growth responds to unanticipated policy shifts and that voters use both on year and midterm elections to balance the two parties on the other hand we find no support for rational retrospective voting we do reconfirm in a fully simultaneous framework the naive retrospective voting literature s finding that the economy has a strong effect on presidential voting we find congressional elections unaffected by the economy except as transmitted by presidential coattails

on the optimal inflation rate abstract in our incomplete markets economy households choose portfolios consisting of risky uninsurable capital and money money is a bubble it has positive value even though it yields no payoff the market outcome is constrained pareto inefficient due to a pecuniary externality each individual agent takes the real interest rate as given while in the aggregate it is driven by the economic growth rate which in turn depends on individual portfolio decisions higher inflation due to higher money growth lowers the real interest rate on money and tilts the portfolio choice towards physical capital investment modest inflation boosts growth rate and welfare

wage inflation in the united kingdom in britain there is little agreement on what determines the growth of wages or indeed on whether a stable wage equation exists in this paper i try to clarify matters in two ways first i aim to represent the data generation process as faithfully and accurately as possible while using with a few modifications the criteria for model selection advanced in davidson et al 1978 second i use five different measures of the pressure of demand rather than just picking on one particular measure 2 it may be helpful at this stage to summarize very crudely the argument and results in section ii having first set out the framework for the rest of the analysis which relates to the period 1961 i 1980 iv i modify the standard real wage model by proxying the desired level of real wages by a moving average of the past level of real wages it is found that the coefficient on the prevailing real wage is equal but of opposite sign to that on the desired wage thus in the long run inflation is independent of the level of real wages the pressure of demand and incomes policy dummies are both found to be significant one would have expected that in the long run the rate of growth of earnings at given price inflation and pressure of demand would respond to differences in the rate of growth of productivity but over the sample period there was no evidence of this once we allowed for incomes policy which implies considerable rigidity in the target rate of growth of wages the analysis so far includes no specifically expectational variables in section iii i use some survey data on wage expectations which have the advantage of being based on quantitative responses one rationale for having wage expectations in a wage equation might be that in a world of staggered contracts where workers care about relative wages they will take into account what they expect to happen to the wages of other workers when settling now a two equation model for wages and wage expectations is presented in the subsequent section and in most respects the results confirm our conclusions from the previous sections however the preferred specification obtained here which encompasses much of the earlier work and probably constitutes progress is one that we have some doubts about and will it is hoped form the basis for future research in this area

facts and challenges from the great recession for forecasting and macroeconomic modeling this paper provides a survey of business cycle facts updated to take account of recent data emphasis is given to the great recession which was unlike most other postwar recessions in the united states in being driven by deleveraging and financial market factors we document how recessions with financial market origins are different from those driven by supply or monetary policy shocks this helps explain why economic models and predictors that work well at some times do poorly at other times we discuss challenges for forecasters and empirical researchers in light of the updated business cycle facts

relative price variability and inflation abstract using italian data from 1954 to 1983 it is found that relative price variability and inflation are positively correlated only during the 1970s and the early 1980s when their relationship appears to be largely induced by movements in the oil price rather than by aggregate demand shocks this result is consistent with the findings of fischer 1981 fischer 1982 for the u s and germany although in contrast to the evidence for these two countries no relationship can be detected between unexpected inflation and relative price variability furthermore the comparison between the three countries provides substantial support for the hypothesis tentatively advanced by fischer 1982 that the correlation between relative price variability and inflation is enhanced by monetary accommodation of real shocks there is also evidence that in italy both variables have been considerably affected by exchange rate movements

opening a can of worms the pitfalls of time series regression analyses of income inequality this paper argues that time series regression analysis is of only very limited use for understanding the determinants of income inequality the argument is based on a combination of results from the time series econometrics literature and several characteristics of inequality itself principally nonstationarity of the data in most inequality regression models and the weak theoretical foundations underlying the models a sample of postwar us data is used to illustrate the problems involved

wage dispersion and inflation we specify a model relating wage dispersion across 16 sectors of uk manufacturing to a rich array of sector specific and macroeconomic variables we find sectoral vacancy dispersion a trade union power proxy short run unemployment and inflation affect wage dispersion in particular we find a strong negative relation between wage dispersion and inflation surprises within a well specified model reinforcing similar findings for the us and israel

the reincarnation of keynesian economics this paper discusses the reemergence of keynesian economics during the past decade it highlights the substantial differences between new keynesian economics and the convictions of early keynesians in particular it points out that new keynesians have adopted many views that were once considered monetarist or classical it concludes that the term keynesian may have outlived its usefulness this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item

earnings unemployment and the allocation of time over time since an individual s labour market history can be described by a markov chain in state space it is possible to calculate the steady states it is natural to interpret the steady state proportion in unemployment for a group of identical workers as the natural rate of unemployment for this group i e it is the expected proportion that would be employed if the environment were to remain constant it is shown how the natural rate of unemployment is different for different groups the model is estimated using data from a large u s income maintenance experiment the predictions of the model with some exceptions bear up well to confrontation by data the empirical findings also accord well with existing evidence on cross section studies of labour supply we find that labour force participation rates implied by the estimated models are positively related to earnings for all age sex and race groups as expected we demonstrate that the elasticities of the unemployment rates for all groups with respect to expected wage rates are negative and large in absolute value in the case of adults while the role of the wage in allocation of time is not novel the existing neoclassical labour literature uses static labour supply models to interpret participation rate studies

management versus ownership ii two fields in economics have developed without much interaction in the past the theory of the firm and mathematical economics the former has accumulated a wealth of thoughts observations on the firm activities without analytical scrutiny the latter has raised the standard of analytical rigor only within simple frameworks which do not fit the nature of the firm activities in the preceding paper ichiishi 1982 a mathematical model of a capitalistic economy was constructed and a rigorous analysis was given to the model this paper presents the economic interpretations implications of the formal study in ichiishi 1982 and shows how the gap between the two fields is bridged it is also intended to serve as a survey article

the history of the phillips curve consensus and bifurcation while the early history of the phillips curve up to 1975 is well known less well understood is the post 1975 fork in the road the left fork developed a theory of policy responses to supply shocks in the context of price stickiness in the non shocked sector its econometric implementation interacts shocks with backward looking inertia the right fork approach emphasizes forward looking expectations that can jump in response to anticipated policy changes the left fork approach is better suited to explaining the postwar us inflation process while the right fork approach is essential for understanding behaviour in economies with unstable macroeconomic environments the history of the phillips curve pc has evolved in two phases before and after 1975 with a widespread consensus about the pre 1975 evolution which is well understood bifurcation begins in 1975 when the pc literature split down two forks of the road with little communication or interaction between the two forks the major contribution of this paper and hence the source of bifurcation in its subtitle is to examine contrast and test the contributions of the two post 1975 forks the pre 1975 history is straightforward and is covered in section i the initial discovery of the negative inflation unemployment relation by phillips popularized by samuelson and solow was followed by a brief period in which policy makers assumed that they could exploit the trade off to reduce unemployment at a small cost of additional inflation then the natural rate revolution of friedman phelps and lucas overturned the policy exploitable trade off in favour of long run monetary neutrality those who had implemented the econometric version of the trade off pc in the 1960s reeled in disbelief when sargent demonstrated the logical failure of their test of neutrality and finally were condemned to the wreckage of keynesian economics by lucas and sargent following the twist of the inflation unemployment correlation from negative in the 1960s to positive in the 1970s the architects of neutrality and the opponents of the keynesian trade off emerged triumphant with two major caveats that their own models based on information barriers were unconvincing and that their core result that business cycles were driven by monetary or price surprises floundered without supporting evidence after 1975 the evolution of the pc literature split in two directions each of which has largely failed to recognize the other s contributions section ii reviews the left fork of the road the revival of the pc trade off in a coherent and integrated dynamic aggregate supply and demand framework that emerged in the late 1970s in econometric tests in theoretical contributions and in intermediate macro textbooks this approach which i have called mainstream is resolutely keynesian because the inflation rate is dominated by persistence and inertia in the form of long lags on past inflation an important difference between the mainstream approach and other post 1975 developments is that the role of past inflation is not limited to the formation of expectations but also includes a pure persistence effect due to fixed duration wage and price contracts and lags between

unions wages and the common interest three models have dominated recent research on the relationship between labor unions wage behavior and national economic performance a simple linear model a parabolic model and a political model this article argues that an unemployment mediated linear model is theoretically preferable in a context of low unemployment encompassing labor movements can be expected to restrain wage demands whereas localized unions have much less incentive to do so in a context of high unemployment localized unions should exhibit wage moderation and the pressure on encompassing unions to restrain wage demands is further accentuated these four models are assessed as predictors of wage changes inflation and misery index levels for 15 industrialized nations over the periods 1960 1973 1974 1979 and 1980 1990 the linear models outperform the parabolic and political models in each of the latter two time periods for the mid to late 1970s the simple linear model performs best but for the 1980s the unemployment medi

banks net interest margin in the 2000s a macro accounting international perspective this paper re examines the determinants of net interest margin nim in the banking industries of 15 developed and emerging economies it presents three main contributions with respect to previous studies first we analyze the determinants of nim in the years leading to the 2008 financial crisis second we account for the role of different accounting standards across countries third we use multi way cluster estimation methodologies which control for cross sectional and time series dependence in macroeconomic and banking variables we find that the introduction of international financial reporting standards ifrss contributed to lower nim variations unexplained by standard accounting variables interest rate volatility is found to be positively and strongly related to nim dynamics whereas inflation risk is often found to be a relevant driver of nim cross country differences

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 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

strategic voting equilibria under the single nontransferable vote previous investigations of strategic voting equilibria in mass electorates have looked only at single member districts i shall investigate such equilibria in multimember districts operating under the single nontransferable vote system what appear to be the most natural equilibria conform to the m 1 rule according to which strategic voting in m seat districts produces exactly m 1 vote getting candidates in equilibrium any others having their support totally undercut this result provides the beginnings of a formal underpinning for reed s recent extension of duverger s law to the japanese case the model also generates specific and empirically testable hypotheses concerning the exceptions to the m 1 rule that one ought to expect in equilibrium i test these hypotheses with japanese data finally the model also reveals a type of strategic voting that is specific to multimember districts i use japanese data again to explore the empirical importance of this kind of strategic voting

public inflation aversion and the political economy of macroeconomic policymaking do the macroeconomic priorities of citizens differ across countries if so what accounts for this variation and what are its consequences for explanations of the choice of monetary institutions macroeconomic policy and international monetary cooperation this article uses survey data from twenty advanced economies to examine individual preferences about macroeconomic priorities the analysis establishes three key findings first the results suggest that economic context defined by inflation and unemployment performance has a substantial impact on the public s economic objectives in a way that is broadly consistent with the specification of utility loss functions in the theoretical political economy literature second the results suggest that there is significant cross country variation in inflation aversion controlling for economic context third some of this variation is accounted for by national level factors affecting the aggregate costs of inflation and unemployment these results have significant implications for optimal monetary policymaking the explanation of variation in economic outcomes and for accounts of the choice of institutional frameworks for policymaking i thank the bank of england the center for basic research in the social sciences and the institution for social and policy studies for research support and jim alt andrew bailey bill bernhard lawrence broz john freeman jeff frieden jim granato shigeo hirano david lake jeff lax simon price rose razaghian ron rogowski david stasavage gabriel sterne mike tomz jim vreeland the editor and two anonymous reviewers for helpful comments all views expressed are those of the author and do not represent those of the bank of england

the optimal inflation rate in new keynesian models should central banks raise their inflation targets in light of the zero lower bound we study the effects of positive steady state inflation in new keynesian models subject to the zero bound on interest rates we derive the utility based welfare loss function taking into account the effects of positive steady state inflation and solve for the optimal level of inflation in the model for plausible calibrations with costly but infrequent episodes at the zero lower bound the optimal inflation rate is low typically less than two percent even after considering a variety of extensions including optimal stabilization policy price indexation endogenous and statedependent price stickiness capital formation model uncertainty and downward nominal wage rigidities on the normative side price level targeting delivers large welfare gains and a very low optimal inflation rate consistent with price stability these results suggest that raising the inflation target is too blunt an instrument to efficiently reduce the severe costs of zero bound episodes

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

energy eroi and quality of life abstract the near and long term societal effects of declining eroi are uncertain but probably adverse a major obstacle to examining social implications of declining eroi is that we do not have adequate empirical understanding of how eroi is linked directly or indirectly to an average citizen s ability to achieve well being to evaluate the possible linkages between societal well being and net energy availability we compare these preliminary estimates of energy availability 1 eroi at a societal level 2 energy use per capita 3 multiple regression analyses and 4 a new composite energy index lambert energy index to select indicators of quality of life hdi percent children under weight health expenditures gender inequality index literacy rate and access to improved water our results suggest that energy indices are highly correlated with a higher standard of living we also find a saturation point at which increases in per capita energy availability greater than 150 gj or eroi above 20 1 are not associated with further improvement to society

voter uncertainty and failure of duverger s law an empirical analysis real world simple plurality elections rarely bear out the strong duvergerian prediction that in equilibrium only two competitors receive votes recent advances in strategic voting theory demonstrate that voter uncertainty about competitors true support levels in the constituency may lead to limited strategic voting and hence incomplete desertion of trailing parties this is the first attempt to estimate empirically the impact of uncertainty on incentives to vote strategically calibrating a model of strategic voting to voting results from simple plurality elections in german constituencies it is found that strategic voters operate under high levels of uncertainty these results support the proposition that uncertainty about party support impedes formation of duvergerian equilibria

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

relative price variability and inflation in an equilibrium price misperceptions model evidence for the uk in this paper we investigate the relationship between relative price variability and inflation in the united kingdom using the equilibrium price misperceptions model of lucas american economic review 1973 63 526 534 we obtain a data consistent version of the equilibrium price misperceptions model linking relative price variability inflation and a small set of key macroeconomic variables we find a significant positive role for inflation in explaining relative price variability and suggest that this may be due to a positive relation between the variance of sector specific shocks and inflation

limits to growth redux a system dynamics model for assessing energy and climate change constraints to global growth abstract this study investigates the notion of limits to socioeconomic growth with a specific focus on the role of climate change and the declining quality of fossil fuel reserves a new system dynamics model has been created the world energy model wem is based on the world3 model the limits to growth meadows et al 2004 with climate change and energy production replacing generic pollution and resources factors wem also tracks global population food production and industrial output out to the year 2100 this paper presents a series of wem s projections each of which represent broad sweeps of what the future may bring all scenarios project that global industrial output will continue growing until 2100 scenarios based on current energy trends lead to a 50 increase in the average cost of energy production and 2 4 2 7 c of global warming by 2100 wem projects that limiting global warming to 2 c will reduce the industrial output growth rate by 0 1 0 2 however wem also plots industrial decline by 2150 for cases of uncontrolled climate change or increased population growth the general behaviour of wem is far more stable than world3 but its results still support the call for a managed decline in society s ecological footprint

eroi of different fuels and the implications for society abstract all forms of economic production and exchange involve the use of energy directly and in the transformation of materials until recently cheap and seemingly limitless fossil energy has allowed most of society to ignore the importance of contributions to the economic process from the biophysical world as well as the potential limits to growth this paper centers on assessing the energy costs of modern day society and its relation to gdp our most important focus is the characteristics of our major energy sources including each fuel s energy return on investment eroi the eroi of our most important fuels is declining and most renewable and non conventional energy alternatives have substantially lower eroi values than traditional conventional fossil fuels at the societal level declining eroi means that an increasing proportion of energy output and economic activity must be diverted to attaining the energy needed to run an economy leaving less discretionary funds available for non essential purchases which often drive growth the declining eroi of traditional fossil fuel energy sources and the effect of that on the world economy are likely to result in a myriad of consequences most of which will not be perceived as good

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

on the anatomy of inflation the variability of relative commodity prices in argentina there is substantial evidence indicating that the inflationary process is not neutral with respect to the structure of relative prices a1though real variables also affect the distribution of commodity prices the variability of relative prices appears to be largely increased by monetary phenomena the general picture emerging from the empirical literature links the cross sectional variability of commodity prices to the variability of the aggregate rate of inflation over time to the rate of unexpected inflation and to the rate of monetary expansion 1 most studies however have dealt with low inflation countries for which it is more difficult to isolate real from monetary effects on relative price changes the purpose of this paper is to analyze in detail the characteristics of relative price behavior within the context of very rapid and variable inflation using disaggregated monthly data for argentina a number of specific aspects of that country s

inflation and relative price variability in the open economy this paper explores the determination of relative price variability in a small open economy operating under a fixed exchange rate a central ingredient of the model presented is the distinction made between traded and non traded goods this distinction leads to a decomposition of total variability into three components the variabilities within each set of goods and between the two sets the analysis also emphasizes the effects of expected versus unexpected inflation on the variability of relative prices the model is tested using annual data for mexico covering the 1951 76 period

united kingdom manpower policy against a background of national economic decline the welsh example chakravarty s p jones d r and mackay r r 1983 united kingdom manpower policy against a background of national economic decline the welsh example reg studies 17 91 104 economic policy has been strongly influenced by a theory which emphasises that only one rate of unemployment is consistent with price stability claims that unemployment is either temporary or voluntary and stresses that lasting reductions in unemployment depend on selective policies designed to encourage adjustments within the labour market this paper outlines experience in wales the evidence is not consistent with the view of unemployment provided by the underlying theory moreover there are considerable problems in applying policies which are designed to reduce the obstacles and frictions to labour market adjustment when unemployment is severe and widespread

on the theory of strategic voting many analyses of plurality rule elections predict the complete coor dination of strategic voting and hence support for only two candidates here i suggest that stable multi candidate support will arise in equilibrium a group of voters must partially coordinate behind one of two challenging candidates in order to dislodge a disliked incumbent in a departure from existing models the popular support for each challenger is uncertain this support must be inferred from the private observation of informative signals such as the social communication of pref erences throughout the electorate or the imperfect observation of opinion polls the uniquely stable voting equilibrium entails only limited strategic voting and hence incomplete coordination this is due to the surprising presence of negative feed back an increase in the degree of strategic voting by others reduces the incentives for an individual to vote strategically the incentive to vote strategically is lower in relatively marginal elections after controlling for the distance from contention of a trailing preferred challenger a calibration of the model applied to the uk general election of 1997 is consistent with the impact of strategic voting and the reported accuracy of voters understanding of the electoral situation it suggests that nearly 50 seats may have been lost by the conservative party due to strategic voting 1 plurality rule elections and strategic voting 1 1 strategic voting and duverger s law plurality rule elections where the winner is the candidate who receives the largest number of votes are vulnerable to strategic voting a voter might well switch away from her preferred candidate and toward a perceived leader in the hope of exerting a greater influence over the outcome of the election this phenomenon has long been the focus of both economic and political scientific study in an influential essay riker 1982b cited droop s 1871 eloquent exposition of the strategic voting problem 1 i oer my grateful thanks to the many friends colleagues seminar participants referees and editors who have oered insightful comments during the long gestation of this paper its antecedents and companion work special thanks go to steve fisher whose empirical analysis of strategic voting raised many of the questions that i seek to answer in this paper and to chris wallace this particular paper brings together much of the analysis previously circulated in the papers a new theory of strategic voting strategic voting under the qualified majority rule and idiosyncrasy information and the impact of strategic voting

colonial legacies and economic growth much of the work on colonialism has been theoretical or anecdotal in this paper i close the gap between the literature on development and new growth theory by testing the effect of colonization on subsequent growth and development in a sample of 63 ex colonial states from 1961 1990 i find that colonies that were held for longer periods of time than other countries tend to perform better on average after independence finally i show that the level of education at the time of independence can help to explain much of the development gap between the former british and french colonies in africa

stability and coordination in duverger s law a formal model of preelection polls and strategic voting this paper investigates the dynamics of the wasted vote phenomenon and duverger s law i construct a theoretical model in order to consider how preelection polls serve to inform the electorate about the relative chances of the candidates and how that information acts over time to decrease the support of the trailing candidate the results shed light on how public opinion polls can aggregate information in the electorate and coordinate voters on the viable candidates in the election specifically i show that in a bayesian game model of strategic voting there exist non duvergerian equilibria in which all three candidates receive votes in the limit these equilibria require extreme coordination however and any variation in beliefs leads voters away from them to one of the duvergerian equilibria thus non duvergerian equilibria are unstable while two party equilibria are not in addition i describe how preelection polls provide information to voters about the viability of candidates and can thus be used by voters to coordinate on a duvergerian outcome

when grilli and yang meet prebisch and singer piecewise linear trends in primary commodity prices abstract in this study we test the prebisch singer hypothesis on the secular decline of relative primary commodity prices with the extended grilli and yang 1988 data set ending at 2010 rather than asking whether it holds for the whole sample period we examine if the hypothesis holds sometimes during the sample period by estimating the piecewise linear trends of primary commodity prices we employ the new l1 trend filtering proposed by kim et al 2009 to estimate the piecewise linear trends we find that the prebisch singer hypothesis holds sometimes but not always for many of the primary commodities in the grilli yang data the strength of the prebisch singer hypothesis has become substantially weaker recently as the relative prices of many primary commodities have increased sharply since around 2000

estimating social effects in matching markets externalities in spousal search this paper investigates the hypothesis that individuals are less willing to marry when there are more potential partners to search amongst and thus when others are also less prone to marry to do this it develops a reduced form method a variation on manski s 1993 model that allows identification of such spillovers in two sided matching markets estimates from this method are internally consistent unbiased robust to different definitions of the marriage market and large enough to warrant attention additional evidence suggests that the effect works via the proposed search mechanism

optimal monetary policy and downward nominal wage rigidity in frictional labor markets empirical evidence suggests that nominal wages in the u s are downwardly rigid this paper studies the optimal long run inflation rate in a labor search and matching framework under the presence of downward nominal wage rigidity dnwr in this environment optimal monetary policy targets a positive inflation rate the annual long run inflation rate for the u s is around 2 percent positive inflation greases the wheels of the labor market by facilitating real wage adjustments and hence it eases job creation and prevents excessive increase in unemployment following recessionary shocks these findings are related to standard ramsey theory of wedge smoothing by following a positive inflation policy under sticky prices the monetary authority manages to reduce the volatility and the size of the intertemporal distortion significantly the intertemporal wedge is completely smoothed when prices are fully flexible since the optimal long run inflation rate predicted by this study is considerably higher than in otherwise neoclassical labor markets the nature of the labor market in which dnwr is studied can be relevant for policy recommendations

money illusion under test abstract we propose a test for the presence of money illusion based on subjective survey information on individual satisfaction with income using data from the german socio economic panel for the period 1993 2003 we cannot reject the null hypothesis of no money illusion

price controls and the variability of relative prices recent literature that explains relative price variability within a partial inforrnation multimarkets framework typically assumes that prices in all markets are deterrnined by market clearing 1 however in many countries a certain number of prices is either directly set by the government or regulated by it in israel for example the government is directly involved in setting the prices of some basic foodstuffs fuels electricity public transportation and a number of other items 2 adjustments in the prices of these goods are made at discrete intervals and are widely and instantaneously disseminated by the media as a result individuals in all markets have up to date inforrnation on that component of the general price level which is set by the government in terrns of the islands paradigm this means that the component of the general price level which is confused with relative price movements is smaller than the same component in an economy in which all prices are freely deterrnined by the market the purpose of this article is to explore the implications of this modified inforrnation structure for relative price variability within a partial inforrnation framework

estimating incumbency advantage without bias in this paper we prove theoretically and demonstrate empirically that all existing measures of incumbency advantage in the congressional elections literature are biased or inconsistent we then provide an unbiased estimator based on a very simple linear regression model we apply this new method to congressional elections since 1900 providing the first evidence of a positive incumbency advantage in the first half of the century incumbency advantage is the most frequently studied factor in the last 15 years of congressional elections research discovery of the increase in incum bency advantage has sparked controversy over its origins historical pattern cur rent magnitude and electoral democratic and policy consequences even the most basic descriptive information about incumbency advantage is flawed be cause every previous measure based on aggregate data in this literature is plagued by selection bias inconsistencies and inefficiencies we prove this result and also propose a new unbiased and statistically efficient measure that is very easy to calculate congressional elections from 1900 to the present fit our theoretical model our empirical reanalyses do not challenge the existing scholarly consen sus that incumbency advantage is much larger than it once was however we do challenge the prevailing belief that incumbency advantage was nonexistent and the evidence that it was negative in house elections during the first half of this century alford and brady 1988 we show instead that the average advantage of incumbency in these elections was about two percentage points in section 1 of this paper we define incumbency advantage and section 2 gives an intuitive sense of the problems identifying it even in ideal electoral sys tems section 3 formally proves that sophomore surge and retirement slump are biased estimates of incumbency advantage and section 4 briefly reveals the flaws

pecuniary externalities in economies with downward wage rigidity abstract a pecuniary externality in economies with downward nominal wage rigidity leads firms to hire too many workers in expansions which leads to too much unemployment in recessions when firms hire more workers firms fail to internalize that competition for workers between firms pushes up the aggregate wage which imposes a negative externality over other firms the externality can be resolved by a macroprudential tax on labor in expansions in the calibrated model the tax reduces the welfare cost of downward nominal wage rigidity by up to 90 as it makes the economy significantly less exposed to unemployment crises
