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

inflation and wage rigidity flexibility in the short run a recent literature uses accurate wage data from payroll records and provides compelling evidence against the conventional belief that nominal wages are downward sticky this paper provides a unique contribution to this literature by conducting a formal analysis of the role of inflation in cyclical wage rigidity flexibility analysis of payroll based wage data from the korean labor market for the period 1971 2014 finds that the degree of downward nominal wage flexibility is countercyclical and the countercyclicality becomes stronger during a deflationary relative to inflationary recession this serves as a counter example to the conventional theory of cyclical wage rigidity jel e24 e32 j30 j64

can currency competition work abstract can competition among privately issued fiat currencies work only sometimes and partially to show this we build a model of competition among privately issued fiat currencies a purely private arrangement fails to implement an efficient allocation even though it can deliver price stability under certain technological conditions although currency competition creates problems for monetary policy it is possible to design a policy rule that uniquely implements an efficient allocation

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

are green hopes too rosy employment and welfare impacts of renewable energy promotion in view of pressing unemployment problems policy makers across all parties jump on the prospects of renewable energy promotion as a job creation engine which can boost economic well being our analytical model shows that initial labor market rigidities in theory provide some scope for such a double dividend however the practical outcome of renewable energy promotion might be sobering our computable general equilibrium analysis of subsidized electricity production from renewable energy sources res e in germany suggests that the prospects for employment and welfare gains are quite limited and hinge crucially on the level of the subsidy rate and the financing mechanism if res e subsidies are financed by labor taxes welfare and employment effects are strictly negative for a broad range of subsidy rates the use of an electricity tax to fund res e subsidies generates minor benefits for small subsidy rates but these benefits quickly turn into significant losses as the subsidy rate exceeds some threshold value

stock market returns and inflation evidence from other countries this paper investigates the relation between common stock returns and inflation in twenty six countries for the postwar period our results do not support the fisher hypothesis which states that real rates of return on common stocks and expected inflation rates are independent and that nominal stock returns vary in one to one correspondence with expected inflation there is a consistent lack of positive relation between stock returns and inflation in most of the countries

downward nominal wage rigidity and state dependent government spending multipliers abstract despite much empirical evidence on business cycle dependent government spending multipliers the theoretical channels underlying such results are uncertain in an environment with involuntary unemployment this paper shows that downward nominal wage rigidity which arises only in recessions can generate business cycle dependent government spending multipliers in line with keynesian views a demand stimulus reduces unemployment in recessions and may not drive up inflation and wages as in expansions thus the positive income effects from reduced unemployment and weaker crowding out effects from a smaller increase in the real interest rate enhance the expansionary spending effects in recessions the theoretical implications are largely consistent with existing empirical evidence on business cycle dependent government spending effects on key macroeconomic variables

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

wage adjustment in the great recession and other downturns evidence from the united states and great britain using 1979 2012 cps data for the united states and 1975 2012 nes data for great britain we study wage behavior in both countries with particular attention to the great recession real wages are procyclical in both countries but the procyclicality of real wages varies across recessions and does so differently between the two countries in ways that defy simple explanations we devote particular attention to the hypothesis that downward nominal wage rigidity plays an important role in cyclical employment and unemployment fluctuations we conclude that downward wage rigidity may be less binding and have lesser allocative consequences than is often supposed

james tobin an appreciation of his contribution to economics jim tobin who died on march 11 2002 at the age of 84 was one of giants of economics of the second half of the twentieth century and the greatest macroeconomist of his generation tobin s influence on macroeconomic theory is so pervasive so much part of our professional acquis that many younger economists often are not even aware that it is his ideas they are elaborating testing criticising refuting or re inventing in this appreciation i consider tobin s scholarly contributions made over a period of more than 50 years tobin received the 1981 nobel memorial prize for his analysis of financial markets and their relations to expenditure decisions employment production and prices i consider his contributions to mean variance portfolio demand and asset pricing theory especially the portfolio separation theorem pitfalls in financial model building portfolio balance and flow of funds models and the credit channel the life cycle model and social security econometric methodology including the tobit estimator and his pioneering work using both time series and cross sectional data to estimate food demand functions economic growth tobin s q the tobin tax the monetary and fiscal policy effectiveness debate first with milton friedman and then with the new classical macroeconomics and real business cycle schools and tobin s approach to methodological questions including microfoundations and aggregation

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

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

time dependent or state dependent wage setting evidence from periods of macroeconomic instability administrative data on monthly wages in iceland during 1998 2010 provide new insight into nominal wage rigidity unlike the data used in previous work ours have a higher frequency minimal measurement error and a long sample including a period of substantial macroeconomic instability we find that the monthly frequency of nominal wage changes is 13 percent although nominal wage cuts are rare their frequency rises following a large macroeconomic shock timing of wage changes is both time dependent and state dependent we find evidence of synchronization of adjustment and contracts of fixed duration but also that inflation and unemployment over the wage spell affect the timing of adjustment

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

keynesian controversies on wages in the general theory keynes advanced two hypotheses about movements in wages and urged their empirical investigation john dunlop lorie tarshis and henry richardson responded to this call with articles published in the economic journal in the late 1930s in turn keynes replied to their findings this exchange is described and the subsequent literature on the cyclical movement of real wages and the rigidity of money wages is outlined

on reputation a microfoundation of contract enforcement and price rigidity we study the impact of reputational incentives in markets characterised by moral hazard problems social preferences have been shown to enhance contract enforcement in these markets while at the same time generating considerable wage and price rigidity reputation powerfully amplifies the positive effects of social preferences on contract enforcement by increasing contract efficiency substantially this effect is however associated with a considerable bilateralisation of market interactions suggesting that it may aggravate price rigidities surprisingly reputation in fact weakens the wage and price rigidities arising from social preferences thus in markets characterised by moral hazard reputational incentives unambiguously increase mutually beneficial exchanges reduce rents and render markets more responsive to supply and demand shocks

downward nominal wage rigidity in canada evidence from micro level data we assess the importance of downward nominal wage rigidity dnwr in canada using both firm and worker level microdata in particular we analyze employer level administrative data from the major wage settlements mws and household based survey data from the survey of labour income dynamics slid

cyclical labor costs within jobs abstract using uk employer employee panel data we present novel facts on how wages and working hours respond to the business cycle within jobs firms reacted to the great recession with substantial real wage cuts and by recruiting more part time workers a one percentage point increase in the unemployment rate led to an average decline in real hourly wages of 2 6 for new hires as well as for job stayers hiring hours worked were substantially procyclical while job stayer hours were acyclical these results show that real wages are not rigid and that the labor costs of new hires are especially flexible

real wage cyclicality of job stayers within company job movers and between company job movers using the british new earnings survey panel data nespd for the period 1975 to 2001 we estimate the wage cyclicality of job stayers those remaining within single jobs in a given company within company job movers and between company job movers we also examine how the proportion of internal and external job moves varies over the business cycle we find that the wages of internal movers are slightly more procyclical and wages of external movers considerably more procyclical than those of stayers notwithstanding a decomposition shows that in britain wage cyclicality arises almost entirely from the procyclicality of wages for job stayers with across and within firm mobility playing a lesser role thus there is little evidence for rigid wage models that imply that employers use changes in job titles as a means of adjusting wages to the business cycle we also show that the distinctions between private and public sectors and between workers covered and uncovered by collective agreements have important impacts on the wage estimates of both stayers and movers

risk and return abstract this paper examines the seasonality in the basic relationship between expected return and risk during 1935 82 the results reveal that the positive relationship between return and risk is unique to january the risk premiums during the remaining eleven months are not significantly different from zero

worker job matches job mobility and real wage cyclicality using the british new earnings survey panel data nespd this paper examines male and female real wage cyclicality over the period 1975 2001 estimation is undertaken separately for job stayers and job movers stayers are defined with respect to single jobs within the company while movers refers to individuals changing jobs both within and between companies core estimates concern real hourly standard wage rates additional features include differentiating between manual and non manual workers and distinguishing between hourly wage rates and hourly wage earnings

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

a picture of job insecurity facing british men this paper considers three aspects of the job insecurity facing british men in the last two decades the probability of becoming unemployed the costs of unemployment in terms of real wages losses and the probability that the continuously employed will experience substantial real wage losses the first of these has not risen in the last two decades the second has risen by around 50 percent and the third has risen particularly for the top skill groups

the seasonal stability of the factor structure of stock returns this paper investigates the month by month stability of a daily returns and correlation coefficients of stock returns b correlation and covariance matrices c number of return generating factors and d the apt pricing relationship the results show that there is a january effect and a small firm effect in stock returns correlation matrices are more stable than covariance matrices but both types of matrices are not stable across months and across the sample groups the number of return generating factors is rather stable most of the time and for most of the sample groups but there is some significant instability that is related to the average correlation coefficients among stocks the apt pricing relationship does not seem to be supported by the two stage process using the maximum likelihood factor analysis the seasonality of common stock returns has received considerable attention in financial economics research studies by officer 23 rozeff and kinney 29 gultekin and gultekin 11 and others have investigated the stock returns of the u s and other countries on a monthly basis they generally have found that on average january returns are significantly higher than the returns for other months banz 1 and reinganum 25 26 have found abnormally high returns in small market value firms and keim 17 has related this to the first few trading days of january schwert 30 points out the current difficulty of explaining these empirical regularities and the need for further investigations several studies have examined seasonality in risk premiums rozeff and kinney 29 found that seasonality appeared in the risk premiums obtained from a twoparameter capm and that january displayed a relatively large risk premium compared with the other months keim 16 also found seasonality in the risk premiums more recently tinic and west 32 examined the risk premiums of the two parameter capm and observed the previously reported seasonality and high january premium they also found that january is the only month in which there is a consistently positive statistically significant relationship between expected return and risk very recently using the two stage procedure with the

potential gains from international portfolio diversification and inter temporal stability and seasonality in international stock market relationships abstract in this paper we find empirical evidence that diversification across countries results in greater risk reduction than diversification across industries our inter temporal stability tests indicate that the longer the time period considered the better proxies ex post patterns of co movement can be for the ex ante co movements of international stock markets our seasonality tests show that international stock market co movements are stable in the september may period but relatively unstable in the may september period
