a reevaluation of the macroeconomic effects of positive trend inflation abstract to date most of the papers which have examined the effects of trend inflation on the properties of new keynesian model were based on relatively simple sticky prices dsge models and whose realism was sometimes questionable in this paper we re evaluate the macroeconomic effects of non zero trend inflation building on the model of ascari 2004 as one of the most cited papers in the literature on the effects of trend inflation we show that the omission of some important theoretical ingredients significantly distorts the results obtained to date we propose a refinement of this model by introducing two theoretical important ingredients namely investment adjustment costs and a roundabout production structure once we add these features to make the model more realistic as commonly for medium scale models we find that the standard new keynesian model without real frictions overestimates the short term macroeconomic effects of a positive trend inflation rate and underestimates those of the long term

the american business cycle continuity and change in recent decades the american economy has experienced the worst peace time inflation in its history and the highest unemployment rate since the great depression these circumstances have prompted renewed interest in the concept of business cycles which joseph schumpeter suggested are like the beat of the heart of the essence of the organism that displays them in the american business cycle some of the most prominent macroeconomics in the united states focuses on the questions to what extent are business cycles propelled by external shocks how have post 1946 cycles differed from earlier cycles and what are the major factors that contribute to business cycles they extend their investigation in some areas as far back as 1875 to afford a deeper understanding of both economic history and the most recent economic fluctuations seven papers address specific aspects of economic activity consumption investment inventory change fiscal policy monetary behavior open economy and the labor market five papers focus on aggregate economic activity in a number of cases the papers present findings that challenge widely accepted models and assumptions in addition to its substantive findings the american business cycle includes an appendix containing both the first published history of the nber business cycle dating chronology and many previously unpublished historical data series

why does the cyclical behavior of real wages change over time the cyclical behavior of real wages has evolved from mildly countercyclical during the interwar period to modestly procyclical in the postwar era this paper presents a general equilibrium business cycle model that helps explain the evolution in the model changes in the real wage cyclicality arise from interactions between nominal wage and price rigidities and an evolving input output structure

can we explain inflation persistence in a way that is consistent with the microevidence on nominal rigidity this paper adopts the impulse response methodology to under stand inflation persistence it has often been argued that existing models of pricing fail to explain the persistence that we observe we adopt a common general framework which allows for an explicit modelling of the distribution of contract lengths and for different types of price setting we also evaluate how far the theories are consistent with recent evidence on price and wage rigidity we find that allowing for a distribution of durations can take us a long way to solving the puzzle of inflation persistence but not all the way yet

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

economic growth and poverty reduction measurement issues using income and non income indicators summary this paper first reviews the debate on the definition of pro poor growth and argues that a relative definition has merits when defining the state of pro poor growth while an absolute definition is most suitable when analyzing the rate of pro poor growth the second contribution is to extend the pro poor growth toolbox to non income indicators the analysis applied to bolivia shows that this extension greatly improves our understanding of the distribution of change in non income indicators of the linkages between progress in income and non income dimensions of poverty and on the incidence of progress in non income outcomes along the income distribution

competing models of international lending activity abstract four competing models of the world bank s lending to developing countries are constructed and econometrically estimated by pooled time series and cross section data the analysis suggests that a model combining economic and political determinants performs best besides per capita income inflation balance of payment and budget deficit external debt and past growth political determinants such as the capitalist climate or political instability are also important as well as a recipient country s former status as a colony or dominion this politico economic model is successfully used to forecast the distribution of ibrd loans and ida credits among the developing countries

post hoc ergo propter once more an evaluation of does monetary policy matter in the spirit of james tobin christina and david romer s paper does monetary policy matter advocates the so called narrative approach to causal inference we demonstrate that this method will not sustain causal inference first it is impossible to distinguish monetary shocks from oil shocks as causes of recessions second a world in which the fed only announces intentions to act cannot be distinguished from one in which it in fact acts third the techniques of dynamic simulation used in the romers study are inappropriate and quantitatively misleading and finally their approach provides no basis for establishing causal asymmetry

technology shocks and labor market dynamics some evidence and theory a positive technology shock may lead to a rise or a fall in per capita hours depending on how hours enter the empirical var model we provide evidence that independent of how hours enter the var a positive technology shock leads to a weak response in nominal wage inflation a modest decline in price inflation and a modest rise in the real wage in the short run and a permanent rise in the long run we then examine the ability of several competing theories to account for this var evidence our preferred model features sticky prices sticky nominal wages and habit formation the same model also does well in accounting for the labor market evidence in the post volcker period

input demand elasticities for heterogeneous labor firm level estimates and an investigation into the effects of aggregation labor economists have paid increasing attention to the estimation of demand elasticities for heterogeneous labor the majority of these studies investigate the effect on wage rates resulting from exogenous changes in factor quantities i e the measurement of elasticities of complementarity examples of these studies abound borjas for example investigates the impact of differences in labor market representation on the earnings of racial groups 8 in another paper borjas defines immigrants as a separate labor group and is able to determine the impact of immigration on the wages earned by natives 9 berger defines labor inputs along education and gender lines thereby allowing for the investigation of changes in the age education composition of the work force on wage rates 5 and grant and hamermesh study the effect of increasing female labor force participation on the wages earned by youth and adults 17 less attention has been paid to the study of the responsiveness of employment to exogenous changes in wage rates i e the measurement of elasticities of substitution less attention has been focused on this issue because the data requirements are more stringent since in order to presume that wage rates are exogenously determined the unit of observation must be small ideally establishmentor firm level data would be used the relative inaccessibility of these type of data has led researchers to use more aggregated figures such as smsa level or industry level data to address microissues as long as wage rates are determined exogenously the unit of observation chosen is appropriate there are real concerns however about the adequacy of more aggregated units to describe the behavior of firms 2 this study addresses the issue of whether micro level data are in fact needed to accurately measure elasticities of substitution among labor groups a firm level data set that includes input

a human development index by income groups summary one of the most frequent critiques of the hdi is that it does not take into account inequality within countries we suggest a methodology which allows to compute the three components and the overall hdi for quintiles of the income distribution this allows comparisons of the level in human development of the poor and non poor within and across countries an empirical illustration shows large discrepancies in human development within the countries especially in africa these discrepancies are lower the higher the hdi is but only weakly so inequality in income is generally higher than inequality in education and life expectancy

monetary policy and real wage cyclicality this article points to the potential role of monetary policy in affecting the degree of real wage cyclicality we show that the degree and direction of real wage cyclicality is determined by the interaction of i the returns to scale in production ii the nature of aggregate shocks and iii monetary policy given that production technology is fairly constant in the short run we suggest that variations in the real wage output covariance depend largely on the combination of the latter two identifying well documented monetary policy phases in six major organization for economic co operation and development oecd countries and accounting for both aggregate demand and supply shocks we provide empirical evidence to support our main theoretical claim

state and prospect of public choice a european view the victory of public choice may not yet have arrived and the share of european contributions may still be small it has nevertheless been argued that there is a great future in public choice three especially promising areas have been indicated by way of example the theory of economic policy politico economic models and international political economy

poverty comparisons over time and across countries in africa abstract we use demographic and health surveys dhs to compare poverty at two or more points in time within and between african countries our welfare measure is an index resulting from a factor analysis of various household characteristics durables and household heads education an advantage of this measure is that for intertemporal and intraregional comparisons we need not rely on suspect price deflators and currency conversion factors the wide availability and similarity of questionnaires of the dhs facilitate comparisons over both time and countries our results generally show declines in poverty during the previous decade largely due to improvements in rural areas

measuring aggregate welfare in developing countries how well do national accounts and surveys agree in a data set for developing and transition economies the author finds that private consumption per capita based on national accounts deviates on average from mean household income or expenditure based on national sample surveys growth rates also differ systematically so that the ratio of the survey mean to the national accounts mean tends to fall over time but there are revealing exceptions to these general findings the aggregate difference in the levels is due more to income surveys than to expenditure surveys and there are strong regional effects for example the severe data problems in the transition economies of eastern europe and central asia means that there is negligible correlation in that region between growth rates from national accounts and those from household surveys

sectoral comovement monetary policy shocks and input output structure the comovement of output across the sector producing nondurables i e nondurable goods and services and the sector producing durables is well established in the monetary business cycle literature however standard sticky price models that incorporate sectoral heterogeneity in price stickiness i e sticky nondurables prices and flexible durables prices cannot generate this feature we argue that an input output i o structure provides a solution to this problem here we develop a two sector model with an i o structure which is calibrated to the u s economy in the model each sector s output affects those of the others by acting as an intermediate input this connection between the sectors provides a channel through which sectoral comovement is induced

the hump shaped behavior of inflation and a dynamic externality we propose a general equilibrium model that explains the empirical evidence of the hump shaped response of inflation to a monetary policy shock the model replaces backward looking indexation a la christiano et al 2005 nominal rigidities and the dynamic effect of a shock to monetary policy journal of political economy 113 1 1 45 with a dynamic externality into the production function of firms the model armed with sticky wages and variable capital utilization has two offsetting effects on real marginal cost over the business cycle first increasing factor prices raise real marginal cost in response to an expansionary monetary policy shock in the intermediate run second a dynamic externality reduces real marginal cost in the short run because it raises productivity in response to an increase in output following the shock overall the resulting short run decrease and intermediate run increase in marginal cost replicate the hump shaped behavior of inflation under purely forward looking price and wage phillips curves

real wages over the business cycle evidence from panel data one topic on which keynes did not disagree with classical economists was the cyclical behavior of real wages keynes 1936 as well as various classical writers predicted that real wages should move countercyclically quoting the general theory p 17 in general an increase in employment can only occur through the accompaniment of a decline in real wages thus i am not disputing this vital fact which the classical economists have rightly asserted as indefeasible this prediction is based on the premise of competition and a given short run capital stock increases in employment then correspond to more intensive use of capital and through diminishing product lower real wages for this reason evidence by dunlop 1938 and tarshis 1939 that real wages move procyclically was viewed as paradoxical both dunlop and tarshis based their findings on an observed positive correlation between real and money wages which given the procyclical movement of money wages implies a positive correlation between

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

investment matching and persistence in a modified cash in advance economy abstract we simulate and estimate a new keynesian search and matching model with sticky wages in which capital has to be financed with cash at least partially our objective is to assess the ability of this framework to account for the persistence of output and inflation observed in the data we find that our setup generates enough output and inflation persistence with standard stickiness parameters the key factor driving these results is the inclusion of investment in the cia constraint rather than any other nominal or real rigidity the model reproduces labor market dynamics after a positive increase in productivity hours fall nominal wages hardly react and real wages go up with some delay regarding money supply shocks we investigate the conditions under which our model specification generates the liquidity effect a fact which is absent in most sticky price models

sticky price models of the business cycle can the contract multiplier solve the persistence problem we construct a quantitative equilibrium model with firms setting prices in a staggered fashion and use it to ask whether monetary shocks can generate business cycle fluctuations these fluctuations include persistent movements in output along with the other defining features of business cycles like volatile investment and smooth consumption we assume that prices are exogenously sticky for a short time persistent output fluctuations require endogenous price stickiness in the sense that firms choose not to change prices much when they can do so we find that for a wide range of parameter values the amount of endogenous stickiness is small thus we find that in a standard quantitative model staggered price setting alone does not generate business cycle fluctuations

measuring poverty in a growing world or measuring growth in a poor world the extent to which growth reduces global poverty has been disputed for 30 years although there are better data than ever before controversies are not resolved a major problem is that consumption measured from household surveys which is used to measure poverty grows less rapidly than consumption measured in national accounts in the world as a whole and in large countries particularly india china and the united states in consequence measured poverty has fallen less rapidly than appears warranted by measured growth in poor countries one plausible cause is that richer households are less likely to participate in surveys but growth in the national accounts is also upward biased and consumption in the national accounts contains large and rapidly growing items that are not consumed by the poor and not included in surveys so it is possible for consumption of the poor to grow less rapidly than national consumption without any increase in measured inequality current statistical procedures in poor

oil and the macroeconomy since world war ii all but one of the u s recessions since world war ii have been preceded typically with a lag of around three fourths of a year by a dramatic increase in the price of crude petroleum this does not mean that oil shocks caused these recessions evidence is presented however that even over the period 1948 72 this correlation is statistically significant and nonspurious supporting the proposition that oil shocks were a contributing factor in at least some of the u s recessions prior to 1972 by extension energy price increases may account for much of post opec macroeconomic performance

the dynamic effects of aggregate demand and supply disturbances we interpret fluctuations in gnp and unemployment as due to two types of disturbances disturbances that have a permanent effect on output and disturbances that do not we interpret the first as supply disturbances the second as demand disturbances demand disturbances have a hump shaped mirror image effect on output and unemployment the effect of supply disturbances on output increases steadily over time peaking after two years and reaching a plateau after five years

the determinants of mortality mortality rates have fallen dramatically over time starting in a few countries in the 18th century and continuing to fall today in just the past century life expectancy has increased by over 30 years at the same time mortality rates remain much higher in poor countries with a difference in life expectancy between rich and poor countries of also about 30 years this difference persists despite the remarkable progress in health improvement in the last half century at least until the hiv aids pandemic in both the time series and the cross section data there is a strong correlation between income per capita and mortality rates a correlation that also exists within countries where richer better educated people live longer we review the determinants of these patterns over history over countries and across groups within countries while there is no consensus about the causal mechanisms we tentatively identify the application of scientific advance and technical progress some of which is induced by income and facilitated by education as the ultimate determinant of health such an explanation allows a consistent interpretation of the historical cross country and within country evidence we downplay direct causal mechanisms running from income to health

on the welfare and cyclical implications of moderate trend inflation abstract the welfare and cyclical implications of moderate trend inflation are addressed in an augmented medium scale dsge model increasing trend inflation from 2 to 4 percent generates a consumption equivalent welfare loss of about 4 percent welfare costs of this magnitude are driven by staggered wage contracts trend growth extended borrowing a roundabout production structure and the interaction between trend inflation and shocks to the marginal efficiency of investment mei a sticky price model abstracting from these features generates much smaller losses moderate trend inflation also has important business cycle implications interacting much more strongly with mei shocks than with productivity or monetary shocks

improving human development a long run view abstract the pessimistic flavour of the human development reports appears to be in contradiction with their own numbers as developing countries fare comparatively better in human development than in per capita gdp terms this paper attempts to bridge this gap by providing a new improved human development index ihdi informed by welfare economics the ihdi is presented here alongside the united nations development programme s undp hdi for the world and its main regions since the late 19th century social dimensions in the ihdi are derived following kakwani journal of development economics 41 1993 pp 307 336 with a convex achievement function whereas a geometric average is employed to combine its dimensions longevity knowledge and income thus the ihdi does not conceal the gap between rich and poor countries and casts a much less optimistic view than the conventional undp index while it fits with the undp concern for international differences the paper s findings highlight main weaknesses in human development dimensions of present day developing countries

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

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

the human development index a critical review since 1990 the united nations development programme undp has published a series of annual human development reports hdrs in which the human development index hdi is computed for each country this index has become an important alternative to the traditional unidimensional measure of development i e the gross domestic product although the index still fails to include any ecological considerations it has broadened the discussion surrounding the evaluation of development unfortunately over the years the hdrs seem to have become stagnant repeating the same rhetoric without necessarily increasing the hdi s utility this paper evaluates how well these reports have lived up to their own conceptual mandate and assesses the ability of the hdi to further the development debate we find that the reports have lost touch with their original vision and the index fails to capture the essence of the world it seeks to portray in addition the index focuses almost exclusively on national performance and ranking but does not pay much attention to development from a global perspective we propose the incorporation of three simple modifications for the index as a first step to overcome these shortcomings 1998 elsevier science b v all rights reserved

optimal monetary policy in a small open economy with staggered wage and price contracts abstract we study optimal monetary policy for a small open economy in a model where both domestic prices and wages are sticky due to staggered contracts the simultaneous presence of the two forms of nominal rigidities introduces an additional trade off between domestic inflation and the output gap we derive a second order approximation to the average welfare losses that can be expressed in terms of the unconditional variances of the output gap domestic price inflation and wage inflation as a consequence the optimal policy seeks to minimize a weighted average of these variances we analyze welfare implications of several alternative simple policy rules and find that domestic price inflation targeting generates relatively large welfare losses whereas cpi inflation targeting performs nearly as well as the optimal rule

changes in business cycles evidence and explanations this paper shows that the volatility of annual real macroeconomic indicators for the united states and the average severity of recessions have declined only slightly between the pre world war i and post world war ii eras recessions have however become somewhat less frequent and more uniform it argues that the advent of macroeconomic policy after world war ii can account for both the observed continuity and change countercyclical monetary policy and automatic stabilizers have prolonged postwar expansions and prevented severe depressions at the same time policy induced booms and recessions have led to continued volatility of the postwar economy

the wage price spiral this paper rehabilitates the old wage price spiral it shows that after an increase in aggregate demand the process of adjustment of nominal prices and nominal wages results from attempts by workers to maintain or increase their real wage and by firms to maintain or increase their markups of prices over wages under continuous price and wage setting the process of adjustment would be instantaneous under staggering of price and wage decisions the adjustment takes time the more inflexible real wages and markups are to shifts in demand the higher is the degree of price level inertia and the longer lasting are the effects of aggregate demand on output

inflation output and markup dynamics with forward looking wage and price setters abstract medium scale new keynesian models are sometimes criticized for their use of backward looking wage and price setting mechanisms and for assuming several types of disturbances including some that would be difficult to interpret economically we propose a dsge model with purely forward looking wage and price setters and parsimoniously chosen disturbances our model emphasizes an interplay between production firms networking and working capital firms can use working capital to finance all or a fraction of their outlays on production factors and use the output of other firms as an input in a what is often called a roundabout production structure our model generates a response of inflation which is mute on impact of a monetary policy shock but highly persistent and very hump shaped afterwards it also yields a large contract multiplier for output two times larger than the one implied by a model relying on indexation only we also show that the response of the price markup can be positive on impact of an expansionary monetary policy shock which differs from the standard countercyclical markup channel emphasized in conventional new keynesian models in contrast to models relying on indexation to past inflation our model produces non inertial responses of inflation to productivity and investment shocks a finding which is broadly consistent with the existing var evidence

stuck on gold real exchange rate volatility and the rise and fall of the gold standard 1875 1939 abstract did the gold standard diminish macroeconomic volatility supporters thought so critics thought not and theory offers ambiguous messages hard regimes like the gold standard limit monetary shocks by tying policymakers hands but exchange rate inflexibility compromises shock absorption in a world of real disturbances and nominal stickiness a model shows how lack of flexibility affects the transmission of terms of trade shocks evidence from the late nineteenth and early twentieth century exposes a dramatic change the classical gold standard did absorb shocks but the interwar gold standard did not supporting the view that the interwar gold standard was a poor regime choice

policy evaluation via composite indexes qualitative lessons from international transparency policy indexes summary international transparency policy indexes itpis help determine billions in investment and aid influence authoritative scholarship and shape policy choices are itpis valid yardsticks of transparency or do they encourage dissimulation most scholarship on index based evaluations focuses on concept indexes e g governance from quantitative approaches this paper presents qualitative insights about itpis in specific and policy indexes in general analyzing three measurement related pitfalls and proposing countermeasures most significantly it shows how indexes presuppose substitutability while policies contain nonsubstitutable necessary policy provisions this dilemma of ontological compatibility means that policies can rank favorably on indexes notwithstanding the absence of lynchpin policy provisions

inflation targeting what inflation rate to target abstract in an economy with nominal rigidities in both an intermediate good sector and a finished good sector and thus with a natural distinction between cpi and ppi inflation rates a benevolent central bank faces a tradeoff between stabilizing the two measures of inflation a final output gap and unique to our model a real marginal cost gap in the intermediate sector so that optimal monetary policy is second best we discuss how to implement the optimal policy with minimal information requirement and evaluate the robustness of these simple rules when the central bank may not know the exact sources of shocks or nominal rigidities a main finding is that a simple hybrid rule under which the short term interest rate responds to cpi inflation and ppi inflation results in a welfare level close to the optimum whereas policy rules that ignore ppi inflation or ppi sector shocks can result in significant welfare losses

nominal wage stickiness and aggregate supply in the great depression building on earlier work by eichengreen and sachs we use data for 22 countries to study the role of wage stickiness in propagating the great depression recent research suggests that monetary shocks transmitted internationally by the gold standard were a major cause of the depression accordingly we use money supplies and other aggregate demand shifters as instruments to identify aggregate supply relationships we find that nominal wages adjusted quite slowly to falling prices and that the resulting increases in real wages depressed output these findings leave open the question of why wages were so inertial in the face of extreme labor market conditions

the impact of affirmative action on labor demand a test of some implications of the le chatelier principle this paper presents an alternative approach to measuring the impact of affirmative action on firms affirmative action is modeled as a series of hiring quotas if the quotas are binding then a firm subject to affirmative action will operate with greater costs of production have less elastic demand for inputs and be less able to substitute between most inputs the results are consistent with the hypothesis that affirmative action regulations significantly constrain firms behavior own wage elasticities are less elastic and most inputs are less substitutable for constrained firms further affirmative action raises costs by 6 5 percent for firms subject to the program copyright 1992 by mit press

increasing returns and unsynchronized wage adjustment in sunspot models of the business cycle a challenge to models of equilibrium indeterminacy based on increasing returns is that required increasing returns for generating indeterminacy can be implausibly large and rise quickly with the relative risk aversion in labor we show that unsynchronized wage adjustment via a relative wage effect can both lower the required degree of increasing returns for indeterminacy to a plausible level and make it invariant to the relative risk aversion in labor consequently indeterminacy and sunspot driven fluctuations can emerge for plausible increasing returns regardless of the relative risk aversion in labor our model generates reasonable dynamics in terms of matching the business cycle and sunspot shocks become more important with labor market friction

good and bad growth the human development reports abstract the 1996 human development report undp 1996 is about economic growth and human development in keeping with past reports in the series it emphasizes the diversity of country performance in improving human development indicators at given rates of growth this article reviews what the human development reports have said on this topic looking at how well the main messages have been supported by data and analysis and how compelling they are as a basis for public action

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

sticky price models of the business cycle can the roundabout production solve the persistence puzzle abstract this paper considers the persistence puzzle unveiled by chari et al 2000 our findings show that endogenously persistent output dynamics are not a puzzle for the standard sticky price model once roundabout production is taken into account we make this point using a new keynesian framework emphasizing an inertial mechanism called the multiplier for price stickiness in the spirit of basu 1995

intermediate goods and business cycles implications for productivity and welfare this paper presents an aggregate demand driven model of business cycles that provides a new explanation for the procyclicality of productivity and simultaneously predicts large welfare losses from monetary nonneutrality the key features of the model are an input output production structure imperfect competition countercyclical markups and for some results state dependent price rigidity true technical efficiency is procyclical even though production takes place with constant returns without technology shocks or technological externalities the paper has observable implications that distinguish it empirically from related work these implications are generally supported by data from u s manufacturing industries copyright 1995 by american economic association

on the timing and efficiency of creative destruction we analyze the timing pace and efficiency of ongoing job reallocation that results from product and process innovation there are strong reasons why an efficient economy ought to concentrate both job creation and destruction during recessions when the opportunity cost of reallocation is lowest incomplete contracting between labor and capital can disrupt this synchronized pattern and decouple creation and destruction transactional difficulties also lead to technological sclerosis characterized by excessively slow renovation government incentives to production may alleviate high unemployment but exacerbate sclerosis in contrast creation incentives increase the pace of reallocation an optimal combination of both policies restores economic efficiency

the comovement between output and prices abstract in this paper i analyze the comovement of us prices and output in the postwar period i use a new set of statistics to characterize the comovement between variables the statistics capture important information about the dynamics in the system the estimation procedure does not require assumptions about the order of integration or the types of assumptions needed for var decompositions i find that the comovement between output and prices is positive in the short run and negative in the long run i show that a model in which demand shocks dominate in the short run and supply shocks dominate in the long run can explain these empirical results while sticky price models with only demand shocks cannot

what determines corruption international evidence from microdata this paper uses a microlevel data set from 49 countries to create a direct measure of corruption which portrays the extent of bribery as revealed by individuals who live in those countries in addition it investigates the determinants of being asked for a bribe at the individual level the results show that both personal and country characteristics determine the risk of exposure to bribery examples are gender income education marital status the city size the country s unemployment rate average education and the strength of the institutions in the country jel k4 d73 p16

monetary policy in a forward looking input output economy this paper examines the implications for monetary policy of sticky prices in both final and intermediate goods in a new keynesian model both optimal policy under commitment and discretionary policy under simple loss functions are studied household utility losses under alternative loss functions are compared additionally the robustness of policy performance to model and shock misperceptions and parameter uncertainty is examined targeting inflation in both consumer and intermediate goods performs better than targeting inflation in one sector targeting price levels of both final and intermediate goods performs significantly better moreover targeting price levels in both sectors yields superior robustness properties

monetary non neutrality in a multisector menu cost model empirical evidence suggests that as much as one third of the u s business cycle is due to nominal shocks we calibrate a multisector menu cost model using new evidence on the cross sectional distribution of the frequency and size of price changes in the u s economy we augment the model to incorporate intermediate inputs we show that the introduction of heterogeneity in the frequency of price change triples the degree of monetary non neutrality generated by the model we furthermore show that the introduction of intermediate inputs raises the degree of monetary non neutrality by another factor of three without adversely affecting the model s ability to match the large average size of price changes a single sector model with a frequency of price change equal to the median rather than the mean generates monetary non neutrality similar to that in our multisector model our multisector model with intermediate inputs generates variation in real output in response to calibrated aggregate nominal shocks that can account for roughly 23 of the u s business cycle

the inequality adjusted human development index a constructive proposal abstract this paper proposes a method to incorporate a concern for distributional inequalities of income education and longevity into the framework of the human development index hdi as it is presently designed by the united nations development programme the paper constructs gini coefficients for a set of 20 developing countries measuring inequalities in annual income educational attainment and life span attainment these calculations are combined with data from the hdi to produce an inequality adjusted human development index iahdi the implications of this proposed index for evaluating and promoting development are considered

market structure and political influence new data on political expenditures activity and success this paper utilizes new data to evaluate the determinants of the political influence of thirty five manufacturing industries on the u s congress during 1976 80 several measures of influence serve to distinguish between political activity and success seller concentration and geopolitical dispersion increase both activity and success but neither industry size nor leading firm size proves significant we test whether political expenditures facilitate obtaining the favors conferred on an industry by its market structure or by influence independent of that strurture statistical inference strongly confirms both roles

staggered price setting staggered wage setting and business cycle persistence abstract staggered price setting and staggered wage setting are commonly viewed as similar mechanisms in generating persistent real effects of monetary shocks in this paper we distinguish the two mechanisms in a dynamic stochastic general equilibrium framework we show that although the dynamic price setting and wage setting equations are alike a key parameter governing persistence is linked to the underlying preferences and technologies in different ways with reasonable parameter values the staggered price mechanism by itself is incapable of while the staggered wage mechanism plays an important role in generating persistence

noisy information distance and law of one price dynamics across us cities abstract us micro price data at the city level suggests that both the volatility and the persistence of law of one price deviations are rising in the distance between us cities a standard two city equilibrium model with trade costs can predict the relationship between volatility and distance but not between persistence and distance we show that if there is imperfect information about the state of nominal aggregate demand with noisy signals that are asymmetric across cities then distance and persistence will be positively correlated our main results are shown to be robust to the introduction of sticky prices and multiple cities

schumpeter and public choice part i precursor to public choice what schumpeter might have done had he lived say another twenty years cannot be known whether he might have continued the line of thought initiated in capitalism socialism and democracy or returned to pure economics cannot be ascertained likewise whether he would have shown interest in and how he might have responded to modern public choice is unknowable still it does seem possible to develop logical implications of his theories that is what i propose to do one other preliminary point needs emphasis the fact that no schumpeterian school of public choice has been initiated by followers is not without importance and requires an explanation that a very distinctive public choice has been developed by others only one of whom downs has indicated any schumpeterian influence is perhaps of greater significance schumpeter is difficult to categorize for he was not only a methodological deviant within the austrian school of economics but a deviant as well from their general normative strictures about capitalism socialism and democracy in any event a schumpeterian public choice would be distinctive and likely to combine highly disparate themes methods and his usual fascinating paradoxes i begin by characterizing those features of modern public choice that would either be downplayed or rejected and then attempt a sketch of the positive content of a schumpeterian public choice

is forward looking inflation targeting destabilizing the role of policy s response to current output under endogenous investment we show that with endogenous investment virtually all monetary policy rules that set a nominal interest rate in response solely to expected future inflation induce real indeterminacy in models with i staggered prices ii staggered prices and staggered wages and iii staggered prices staggered wages and firm specific capital in i policy s response to current output can help significantly in ensuring determinacy with an infinite labor supply elasticity but little with empirically plausible labor supply elasticity in ii responding to output always helps a great deal though under low price stickiness and without capital adjustment cost it may call for a moderate response to output in order to ensure determinacy for a wide range of response to inflation in iii even a tiny response to output can always render equilibrium determinate for a wide range of response to inflation

monetary factors in the great depression this paper examines the role of monetary policy in the early stages of the great depression and considers the mechanism whereby this policy may have affected real activity i conclude that the depression was preceded by a dramatic shift towards a highly contractionary monetary policy the economic impact of this policy seems unlikely to have come through the conventional keynesian channels of a shortage of liquidity and high ex ante real interest rates but instead may have operated through unanticipated deflation and after 1930 through the disruption of financial intermediation as a consequence of the banking panics

commodity choice behavior with pigeons as subjects starting from an initial baseline budget line income compensated price changes always resulted in substitution effects consistent with the slutsky hicks theory this behavior cannot be explained by a simple random behavior model similar changes in relative prices that did not originate from the initial baseline budget line resulted in undersubstitution effects the composition of consumption changed in the expected direction but the magnitude of change was not large enough to be consistent with the initial commodity bundle chosen these undersubstitution effects are not explainable by shifting preference patterns or anchoring effects found in inconsistent choice sequences with human subjects
