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

real sectoral spillovers a dynamic factor analysis of the great recession abstract dynamic factor methods are used to identify the impact of common and idiosyncratic shocks on sixteen u s nonfarm business sectors this paper then studies changes in the transmission of these shocks across sectors during the great recession and evaluates the cross sectoral spillovers the great recession is found to be largely a time of heightened impact of common shocks which accounts for 3 4 of aggregate volatility and large spillovers of negative finance related shocks in addition prior to the recession aggregate fluctuations are mainly driven by sector specific shocks in contrast with findings from previous studies

eductive stability in real business cycle models we reexamine issues of coordination in the standard rbc model is the unique rational expectations equilibrium attainable by rational agents who contemplate the possibility of small deviations from equilibrium surprisingly we nd that coordination cannot be expected even with strong common knowledge assumptions rational agents anticipating small but persistent deviations are led to take actions that eventually contradict the common knowledge assumption this impossibility theorem for eductive learning is not fully overcome when adaptive learning is incorporated into the framework

marketization and perceptions of social protection in china s cities summary one of the major challenges for china s ongoing economic reforms is how best to handle the social protection needs of its citizens in the face of mounting insecurities resulting from the marketization process we first argue that china has adopted a middle road in its approach to balancing marketization and stability we then proceed to draw on a large survey of people living in china s cities to examine how successful china s middle road has been perceived to be through the eyes of its urban populace our findings support the view that the market and state are complements and that fostering sustained economic growth requires sound social protection arrangements

the brevity and violence of contractions and expansions abstract early studies of business cycles argued that contractions in economic activity were briefer shorter and more violent rapid than expansions this paper systematically investigates this claim and in the process discovers a robust new business cycle fact contractions in employment are briefer and more violent than expansions but we cannot reject the null of equal brevity and violence for expansions and contractions in output the difference arises because employment typically lags output around peaks but they coincide in their troughs we discuss the performance of existing business cycle models in accounting for this fact and conclude that none can fully account for it we then show that a business cycle model with asymmetric adjustment costs on employment and a choice of when to scrap old technologies can account for the business cycle fact both qualitatively and quantitatively

new keynesian perspectives on labor market dynamics abstract we find that demand shocks play an important role for business cycle fluctuations in unemployment and job vacancies the reason is that those shocks give a strong incentive to demand constrained firms to adjust production and thereby labor input furthermore we argue that whether real wage rigidity a la hall 2005 employment fluctuations with equilibrium wage stickiness american economic review 95 50 65 helps explain the remaining part of the unemployment volatility puzzle depends critically on assumptions regarding the form of the wage bargain between firms and workers real wage rigidity tends to generate volatility in employment only in the case in which hours are chosen efficiently if on the other hand the real wage is allowed to affect firms s choices of hours directly the feature of real wage rigidity loses its ability to increase employment volatility

welfare states in hard times welfare states have been subject to a host of conflicting pressures from high unemployment rising income inequality population aging tax competition rising budget deficits and debts slow growth and fears that economic dynamism was being stifled by excessive taxes and benefit levels nevertheless total spending on welfare has edged up in many countries and cuts in rates of benefit have generally been fairly modest the generosity of the welfare state has an enormous influence on poverty and income inequality and still appears to be popular in most of europe suggestions that society would benefit from reduced working time must reckon with the fact that it is paid work which generates the tax revenue required to fund welfare spending

is globalisation undermining the welfare state this paper analyses the evolution of the welfare states in the majority of oecd countries during the pre globalisation 1946 80 and globalisation 1980 2000 periods our purpose is to find out whether globalisation has produced a convergence towards a smaller welfare state funded increasingly by non mobile factors such as labour property and consumption rather than by mobile factors such as capital the data presented here challenge the claims about such a convergence showing that social public expenditures and public employment have continued to expand during the globalisation period in most oecd countries we also show that the welfare states remain rooted in the political traditions that have governed them copyright 2004 oxford university press

real business cycles and labor markets with imperfectly flexible wages abstract one of the principal criticisms of real business cycle models is that the assumptions made about labor markets do not accord with the actual structure of these markets this paper replaces the standard spot labor market with a market characterized by imperfectly flexible wages which corresponds to impressions of contractual labor relations it is found that the behavior of the model in terms of the predicted variances and correlations is similar to that of the standard real business cycle model but that the variability of hours worked and the correlation of hours worked with wages will depend on the structure of the labor market

cyclical productivity in a model of labor hoarding abstract this paper develops a dynamic model of labor hoarding to explain two empirical facts the cyclical behavior of total factor productivity and the dynamic correlations of sectoral productivity with aggregate variables the model features convex costs of adjusting the labor force which induce firms to vary the intensity of labor utilization over the cycle in particular cyclical variations in labor effort take place as a response to expected future changes in industry conditions i test the restrictions imposed by the model for several two digit manufacturing industries under different assumptions about market structure and returns to scale then using the assumption that aggregate variables carry information about future changes in industry conditions i simulate the model s dynamic response of hours and productivity to aggregate innovations and compare them to those estimated from the data

north american tomato market a spatial equilibrium perspective this paper studies the north american tomato market in a world market perspective for this purpose a spatial equilibrium model with endogenous prices is constructed and solved by quadratic mathematical programming method six scenarios involving the impacts from transportation costs tariffs and north american free trade agreement nafta were modelled the solutions illustrate their impacts on production consumption trade flows prices and net social welfare due to nafta mexico became the main tomato exporter to the usa

evaluating unemployment policies what do the underlying theories tell us the paper surveys unemployment policies for advanced market economies and evaluates them by examining the predictions of the underlying macroeconomic theories the basic idea is that for the most part different unemployment policy prescriptions rest on different macroeconomic theories and our confidence in the prescriptions should depend at least in part on theories ability to predict some salient stylized facts about unemployment behavior the paper considers four types of policies laissez faire demand management policies supply side policies and structural policies copyright 1995 by oxford university press

overtime labor employment frictions and the new keynesian phillips curve abstract this paper presents a new keynesian nk model that is extended to differentiate between straight time and overtime work the model proposes that the new keynesian phillips curve nkpc should be estimated with marginal cost measured in terms of overtime labor the resulting coefficient estimates are in accordance with theory and statistically significant for the hybrid nkpc which allows for backward looking price setters but not for the purely forward looking nkpc in the hybrid model backward looking behavior is found to be predominant the paper also shows that the incorporation of employment frictions predetermined employment and convex adjustment costs in nk models helps reconcile the frequent price changes found in the microdata with the degree of sluggishness in inflation adjustment to output changes at the macro level

tax disturbances and real economic activity in the postwar united states abstract this paper investigates the macroeconomic effects of cyclical fluctuations in marginal tax rates it finds that systematically including tax variables in a standard real business cycle model substantially improves the model s ability to reproduce basic facts about postwar u s business cycle fluctuations in particular modeling fluctuations in personal and corporate income tax rates increases the model s predicted relative variability of hours and decreases its predicted correlation between hours and average productivity fluctuations in tax rates produce large substitution effects that alter the leisure labor supply decision

international debt and world business fluctuations abstract the international transmission of real productivity disturbances is examined in an optimizing model with two countries each inhabited by an infinitely lived representative consumer producer we analyze the dynamics of output consumption investment interest rates and net external debt foreign productivity shocks can have positive or negative impacts on domestic output and international debt depending on the intertemporal distribution of the shocks transient foreign shocks are shown to be positively transmitted and lead to increased domestic indebtedness while permanent foreign shocks are negatively transmitted and lead to a decline in domestic indebtedness

nobel lecture the transformation of macroeconomic policy and research what i am going to describe for you is a revolution in macroeconomics a transformation in methodology that has reshaped how we conduct our science prior to the transformation macroeconomics was largely separate from the rest of economics indeed some considered the study of macroeconomics fundamentally different and thought there was no hope of integrating macroeconomics with the rest of economics that is with neoclassical economics others held the view that neoclassical foundations for the empirically determined macro relations would in time be developed neither view proved correct finn kydland and i have been lucky to be a part of this revolution and my address will focus heavily on our role in advancing this transformation now all stories about transformation have three essential parts the time prior to the key change the transformative era and the new period that has been affected by the change and that is the story i am going to tell how macroeconomic policy and research changed as a result of the transformation of macroeconomics from constructing a system of equations of the national accounts to an investigation of dynamic stochastic model economies

cyclical factor utilization abstract we introduce procyclical labor and capital utilization as well as costs of rapidly increasing employment into a business cycle model plausible variations in factor utilization enable us to explain observed variability of real gnp with considerably smaller economy wide disturbances the costs of adjustment create very interesting and realistic lead and lag relationships employment does not peak until a full quarter after output workweeks effort capital utilization and productivity all sharply lead the business cycle

integration and the structure of public spending he voluminous tax competition literature suggests that increased economic integration leads to reduced tax rates and suboptimal levels of government spending as countries compete for mobile factors of production integration may influence not only the size of the government but also the structure of public spending comprehensive studies analyzing the effect of integration on the overall structure of government spending are rare however this article fills this void by providing an empirical analysis of the effects of economic integration on the overall structure of public spending in a number of organisation for economic co operation and development countries using panel data on the different government spending components for the period 1970 to 2002 the authors find that integration negatively influences government consumption and investment but that there is no empirical evidence that transfers are positively or negatively affected by integration as suggested by the compensation and efficiency views respectively less

asymmetric phase shifts in u s industrial production cycles abstract we identify cyclical turning points for 74 u s manufacturing industries and uncover new empirical regularities a industries tend to comove between expansion and contraction phases over the business cycle b clusters of industry turning points are highly asymmetric between peaks and troughs troughs are much more concentrated and sharper than peaks c the temporal pattern of phase shifts across industries supports the spillovers through input output linkages and d macroeconomic shocks such as unanticipated changes in monetary policy government spending oil prices and financial conditions are significant drivers of industrial phase shifts

threshold behavior and aggregate fluctuation this paper concerns a propagation mechanism in an economy where many individuals follow a threshold rule and interact with a positive feedback we derive an asymptotic distribution of the propagation size when the number of the agents tends to infinity the propagation distribution exhibits a slower convergence to a deterministic value than it would if the agents followed a smooth adjustment policy this gives rise to significant aggregate fluctuations in a finite lumpy adjusting economy even when the agents are hit by small independent shocks

introduction to sunspots and lotteries abstract this introduces the symposium on sunspots and lotteries two stochastic general equilibrium concepts sunspot equilibrium se and lottery equilibrium le are compared it is shown that for some general pure exchange economies which allow for consumption nonconvexities or moral hazards the set of le allocations is equivalent to the set of se allocations provided that the randomizing device can generate events of any probability journal of economic literature classification numbers d51 d82 d84 e32

interpreting a stochastic monetary growth model as a modified social planner s problem abstract using a stochastic cash in advance growth model similar to that studied by cooley and hansen 1989 it is demonstrated that the competitive monetary equilibrium can be expressed as the solution to a modified social planner s problem hence by employing standard dynamic optimization techniques and the second welfare theorem to the modified social planner s problem the equilibrium of the monetary economy can be studied

indivisible labor lotteries and equilibrium abstract this paper considers an economy where labor is indivisible and agents are identical although the discontinuity in labor supply at the individual level disappears as a result of aggregation it is shown that indivisible labor has strong consequences for the aggregate bahavior of the economy it is also shown that optimal allocations involve lotteries over employment and consumption

an estimate of a sectoral model of labor mobility this paper develops a model of sectoral labor mobility and tests its main implications the model nests two distinct hypotheses on the origin of mobility a sectoral shocks and b worker employer mismatch we estimate the relative importance of each hypothesis and find that the bulk of labor mobility is caused by mismatch rather than by sectoral shift we then try to put a value on society s match specific information that is we ask to what extent the availability of the option to change jobs raises gnp we find that the mobility option raises expected earnings by roughly between 8 5 percent and 13 percent of labor earnings which translates to an increase in gnp of between 6 percent and 9 percent

indivisible labor and the business cycle abstract a growth model with shocks to technology is studied labor is indivisible so all variability in hours worked is due to fluctuations in the number employed we find that unlike previous equilibrium models of the business cycle this economy displays large fluctuations in hours worked and relatively small fluctuations in productivity this finding is independent of individuals willingness to substitute leisure across time this and other findings are the result of studying and comparing summary statistics describing this economy an economy with divisible labor and post war u s time series

labor productivity and the business cycle can r b c models be saved abstract standard r b c models do not enable one to reproduce the main labor market stylized facts employment is more variable than productivity and average productivity leads the cycle in order to mimic these features we consider a model with indivisible labor labor hoarding and adjustment costs the model is then simulated and compared to u s stylized facts we show that government expenditure shock and some specific labor adjustment costs are necessary to explain the lead of the average productivity over the business cycle

real business cycle theory wisdom or whimsy abstract this paper assesses the empirical plausibility of the view that aggregate productivity stocks account for most of the variability in post world war ii us output we argue that the type of evidence forwarded by proponents of this proposition is too fragile to be believable the answer could be 70 as kydland and prescott 1989 claim but the data contain almost no evidence against either the view that the answer is really 5 or that the answer is really 200 moreover point estimates of the importance of technology shocks are extremely sensitive to small perturbations in the theory depending on the sample period investigated allowing for labor hoarding behavior in an otherwise standard rbc model reduces the ability of technology shocks to account for aggregate fluctuations by between 30 to 60

ad valorem tariff and spatial equilibrium models the objectives of this article are to illustrate theoretically and empirically how to incorporate an ad valorem tariff in spatial equilibrium models and show the equivalence of three approaches primal dual and mcp of spatial equilibrium trade modelling the article lays out in detail the theory empirical applications and the results for all three approaches so that trade modellers can easily follow and apply them in their work the primal approach is commonly used by spatial equilibrium modellers though the dual approach corresponds to the textbook depiction of consumer surplus producer surplus and gains from trade the mixed complementarity problem mcp is not commonly used by spatial equilibrium modellers though it is relatively simpler if the modeller knows the equilibrium conditions this article also presents advantages and disadvantages of each approach

effects of trade diversion and trade creation of mercosur on us and world apple markets apples are the third most valuable fruit in the united states and account for 18 of us fruit exports chile is a major competitor to the united states in the mercosur market since it is one of the leading apple producing countries and enjoys the tariff reductions as a member of mercosur consequently chilean exports displace us exports in mercosur in addition other mercosur members import more from lower cost chile leading to a reduction in production and an increase in consumption in these countries this study develops a theoretical and an empirical model of world apple market to quantify the trade diversion and trade creation effects of the mercosur free trade agreement and to estimate the welfare impacts

why sweden s welfare state needed reform according to professor walter korpi the swedish economy would be in better shape if leading politicians had paid less attention to the advice from an influential group of swedish academic economists allegedly hostile to the welfare state their claim that high taxes and extensive social security programmes have strong adverse effects on aggregate economic performance rested on a politically biased reading of comparative international data in purporting to show that sweden had fallen behind other comparable countries the sclerosis diagnosis they set the stage for cutbacks in the welfare state and a major tax reform involving substantially lower marginal tax rates apart from creating inequality at a negligible gain in efficiency the very same reforms may also explain why sweden ran into a macroeconomic tailspin in the early i 990s rather than an instructive case study of the ultimate consequences of a long term obsession with income equality and social protection the exceptional economic crisis can be traced to severe macroeconomic policy blunders the views of professor korpi are quite familiar for anyone that has followed the swedish debate over the last decade supporters of the welfare state applaud professor korpi for revealing the ideological bias underlying the evidence presented in support of the sclerosis diagnosis some swedish economists rather thank of him as a modern day don quixote eager to pick a fight with imaginary villains being a swede and a professor of economics i can hardly claim the status of an impartial observer i certainly believe that harberger triangles convey information and i am convinced that most of the recently implemented reforms make sense nevertheless i believe that professor korpi raises important issues many of the accusations made against the welfare state in sweden and elsewhere rest on evidence which does not survive normal academic scrutiny in their capacity as policy advisors academic economists far from always live up to the standards of the seminar room speculation and sweeping generalisations are poor substitutes for facts and empirical investigations like professor korpi i doubt that very important insights on the harmfulness of the welfare state can be gained from comparative aggregate data over the period i970 90 swedish economic growth was below the oecd average at the same time the public sector was very large however

understanding european unemployment with a representative family model abstract a representative family model with indivisible labor and employment lotteries has no labor market frictions and complete markets nevertheless its aggregate responses to an increase in government supplied unemployment insurance ui and to an increase in microeconomic turbulence are qualitatively similar to those in two macromodels with labor market frictions and incomplete markets namely the matching and search island models in ljungqvist and sargent 2007a understanding european unemployment with matching and search island models journal of monetary economics this issue because there is no frictional unemployment in the representative family model an increase in employment protection ep decreases aggregate work because the representative family substitutes leisure for work an effect opposite to what occurs in matching and search island models heterogeneity among workers highlights the economy wide coordination in labor supply and consumption sharing that employment lotteries and complete markets achieve in the representative family model a high disutility of labor makes generous ui cause very low employment levels

a spatial equilibrium analysis of trade policy reforms on the world wheat market since a few countries produce most of the world s wheat and consumption is widespread across the world wheat is one of the most commonly traded agricultural commodities in recent years the wheat market has been going through difficult phases as wheat prices are depressed the fall in wheat prices is attributed to a supply glut and restrictive trade barriers this study develops a large scale spatial equilibrium trade model for wheat to analyse the effects of removing trade barriers tariffs and subsidies on each country s region s price supply demand trade welfare and bilateral trade flows the results show that trade liberalization leads to an increase decrease in prices in the exporting importing countries production and exports increase in the exporting country and consumption and imports increase in the importing country consequently the volume of trade also increases the welfare of most countries rises and thus world welfare also rises

overtime effort and the propagation of business cycle shocks abstract this paper presents and estimates a variant of hansen and sargent s 1988 real business cycle model with straight time and overtime the model presented has only one latent variable the state of technology yet it does a better job propagating and magnifying shocks than the labor hoarding models which incorporate unobserved effort this model as well as a version of burnside eichenbaum and rebelo s 1993 labor hoarding model is estimated using maximum likelihood the maximum likelihood parameter estimates are compared to those using gmm

the aggregate effects of sectoral reallocations abstract can a one time permanent change in the fundamentals behind the sectoral composition of the economy prompt an aggregate downturn can this downturn be non negligible even if one uses us data to determine the relative size of gross vs net job flows and the importance of job creation costs can one consider the military build down of the 1990s as a plausible cause for the 1990 1991 recession do sectoral reallocations generate responses that are qualitatively similar to productivity shocks we use a variant of the mortensen pissarides 1994 review of economic studies 61 397 415 job creation destruction model calibrate it to us labor market data and run experiments that suggest one can answer yes to all these questions

straight time and overtime in equilibrium abstract we formulate an equilibrium model of straight time and overtime wages by imposing restrictions on agents consumption sets and using a commodity space that includes employment lotteries we extract some time series implications from a linear quadratic approximation to our model evaluated at particular parameter values we use our model informally to interpret some features of observed time series for wages and employment

does europe need neoliberal reforms this paper examines the neoliberal claim that the only way to achieve sustainable growth and full employment is to abandon keynesian macroeconomic management and the welfare state and bring back flexible labour market policies it summarises the conditions required for neoliberal policies to produce such an outcome and their relevance to contemporary economic social and political realities this is followed by an empirical comparison of the economic performance and social well being of seven advanced economies widely regarded as leading proponents of the three models of capitalism liberal corporatist and social democratic contrary to the claim the model that performs best is the one that has least in common with the neoliberal economic orthodoxy a conclusion that is likely to be of particular relevance in the present century

production growth and business cycles ii new directions abstract this paper outlines new directions for investigations of real business cycle models consideration of stochastic growth of exogenous and endogenous forms analysis of suboptimal outcomes arising due to externalities of distorting taxes and implications of labor market heterogeneity

sticker shocks using vat changes to estimate upper level elasticities of substitution we estimate the upper level elasticity of substitution between goods and services of a nested aggregate ces preference specification we show how this elasticity can be derived from the long run response of the relative price of a good to a change in its vat rate we estimate this elasticity using new data on changes in vat rates across 74 goods and services for 25 european union countries from 1996 through 2015 depending on the level of aggregation we find a vat pass through rate between 0 4 and 0 7 this implies an upper level elasticity of 3 at the lowest level of aggregation with 74 categories and 1 cobb douglas preferences at a high level of aggregation that distinguishes 10 categories of goods and services

can world real interest rates explain business cycles in a small open economy abstract while the world real interest rate is potentially an important mechanism for transmitting international shocks to small open economies much of the recent quantitative research that studies this mechanism concludes that it has little effect on output investment and net exports we re examine the importance of world real interest rate shocks using an approach that reverses the standard real business cycle methodology we begin with a small open economy business cycle model but rather than specifying the stochastic processes for the shocks and then solving and simulating the model to evaluate how well these shocks explain business cycles we use the model to back out the shocks that are consistent with the model s observable endogenous variables then we use variance decompositions to examine the importance of each shock we apply this methodology to canada and find that world real interest rate shocks can play an important role in explaining the cyclical variation in a small open economy in particular they can explain up to one third of the fluctuations in output and more than half of the fluctuations in net exports and net foreign assets

a dynamic small open economy model with involuntary unemployment it is well known that real business cycle small open economy soe models rely on greenwood hercowitz and huffman 1988 preferences to match the countercyclical trade balance observed in open economies as well as other second moments while standard preferences a la king plosser and rebelo 1988 are commonly labelled ineffective owing to their inability to yield the countercyclical trade balance in this paper i show that an soe model with standard preferences and involuntary unemployment with efficient risk sharing can obtain a countercyclical trade balance and match main empirical regularities in small open economies il est bien connu que les modeles de cycles d affaires reels dans une petite economie ouverte peo comptent sur des preferences a la greenwood hercowitz et huffman 1988 pour etre compatibles avec la balance commerciale contre cyclique observee dans les economies ouvertes ainsi que sur d autres second moments alors que les preferences standards a la king plosser et rebelo 1988 sont considerees comme ineffectives a cause de leur inhabilitea engendrer la balance commerciale contre cyclique dans ce texte l auteur montre qu un modele de peo avec preferences standards et chomage involontaire et partage efficient du risque peut engendrer une balance commerciale contre cyclique et s arrimer aux principales regularites observees dans les petites economies ouvertes

labor hoarding and the business cycle this paper investigates the sensitivity of solow residual based measures of technology shocks to labor hoarding behavior using a structural model of labor hoarding and the identifying restriction that innovations to technology shocks are orthogonal to innovations in government consumption we estimate the fraction of the variability of the solow residual that is due to technology shocks our results support the view that a significant proportion of movements in the solow residual are artifacts of labor hoarding behavior specifically we estimate that the variance of innovations to technology is roughly 50 percent less than that implied by standard real business cycle models in addition our results suggest that existing real business cycle studies substantially overstate the extent to which technology shocks account for the variability of postwar aggregate u s output

spillovers from foreign direct investment within or between industries this paper contributes an estimation framework to measure both technological and linkage externalities from foreign direct investment fdi empirical research dealt mainly with intra industry spillovers from fdi with restrictive treatment of inter industry effects until recently however as optimal organization of the multinational corporation mnc involves minimization of profit losses due to leakage of technical information to competitors host country firms within the mnc s sector experience limited productivity gains ensuing fdi host country producers in other sectors may benefit for example mncs transfer knowledge to local downstream clients or outsource to local upstream suppliers hence fdi substitutes within sector domestic investment but complements it across sectors the net impact on aggregate capital formation by host country producers hinges on the interaction between linkages and spillovers estimations based on the colombian manufacturing census yield the sectoral pattern of fdi spillovers displaying knowledge propagation between but not within industries the findings reveal outsourcing relationships of mncs with local upstream suppliers as the channel of diffusion

technical progress and aggregate fluctuations abstract we compare the cyclical fluctuations exhibited by a stochastic growth model under various stochastic processes governing technical change all of which are highly autocorrelated the results obtained are quite sensitive to the precise form of this stochastic process in particular the results depend on whether growth is deterministic or stochastic and in each case are quite sensitive to the persistence of an innovation the model does a relatively poor job of accounting for features of observed business cycles when technical change is difference stationary and does a better job when technical change is trend stationary but highly autocorrelated

effects of global trade liberalization on softwood lumber markets this study develops a world spatial equilibrium softwood lumber model comprised of the major importing and exporting countries regions to analyse the impacts of global trade reform on the world softwood lumber market the results show that free trade leads to an increase in lumber trade and canadian producers and us consumers are the biggest beneficiaries trade liberalization improves the overall world welfare as world producer and consumer surpluses increase the result highlights the importance of moving towards free trade in the global softwood lumber market

conjoint analysis of industry location preferences evidence from the softwood lumber industry in the us conjoint analysis ca was used to study location preferences among members of the softwood lumber industry in the southern and western regions of the us this industry was selected as an example of a resource based industry to test several hypotheses derived from location theory decision makers owners and managers identified price of logs and distance to sources for logs as the most important location factors a secondary category included wages and energy costs other variables such as cost of land quality of access roads and distance to markets are less important there were statistically significant differences in the part worth estimates of raw materials and wage costs among decision makers but not between regions in an ordered model for site preference marginal analysis of the price of logs stressed its importance as the major location factor in the softwood lumber industry

productivity shocks and real business cycles abstract productivity shocks play a central role in real business cycles as an exogenous impulse to macroeconomic activity however measured solow prescott residuals do not behave as an exogenous impulse rather econometric evidence provided in this paper indicates that 1 money interest rates and government spending granger cause these impulses and 2 a substantial component of the variance of these impulses between one quarter and one half is attributable to variations in aggregate demand these results are robust to a number of econometric issues including measurement errors specification of the production function and certain forms of omitted real variables

the swedish experiment the deterioration of the economic performance in sweden from about 1970 was to some extent the result of a number of exogenous shocks and unnecessary policy mistakes it was however also related to basic changes in the economic and social system in sweden in the late 1960s and early 1970 when government spending taxes and regulations started to expand dramatically it is also argued in the paper that problematic political economic and social mechanisms had become embedded in the long term dynamics of the system itself these various experiences are the background for recent reforms and retreats of the swedish experiment

business cycles and labor market search the quantitative implications of labor market search for economic fluctuations are evaluated in the context of a real business cycle model incorporating labor market search into the model is found to improve its empirical performance along several dimensions in particular hours now fluctuate substantially more than wages and the contemporaneous correlation between hours and productivity falls in addition the model replicates the observation that output growth displays positive autocorrelation at short horizons overall the empirical results suggest that the labor market search environment embodies a quantitatively important propagation mechanism copyright 1996 by american economic association

the welfare impacts of u s trade restnctions against the canadian softwood lumber industry a spatial equilibrium in this paper we estimate the production and welfare impacts of various u s trade restrictions on canadian lumber after building a model that incorporates the regional character of the north american lumber market we simulate a variety of tariffs and quotas now advocated by a number of u s lawmakers we find that the tariff losses incurred by canadian producers could be substantial depending on the elasticity of their export supply voluntary restraint agreements however might lead to canadian gains as high as 40 per cent of their pre existing profits

inflation and labor market dynamics revisited abstract we demonstrate that the presence of an empirically plausible labor adjustment decision at the firm level rationalizes strategic complementarities in price setting which help explain inflation dynamics those strategic complementarities are typically assumed away in the related existing literature this motivates our revisiting of inflation and labor market dynamics

productivity shocks and business cycles this note uses two measures of productivity growth the solow residual and the dual residual from the cost function to test competing theories of the cycle in a number of oecd countries the empirical results indicate that both demand and supply shocks play a role in driving economic cycles and therefore refute the stronger real business cycle hypothesis

welfare state retrenchment revisited entitlement cuts public sector restructuring and inegalitarian trends in advanced capitalist societies in recent years it has become commonplace for comparativists to emphasize the resilience of welfare states in advanced capitalist societies and the failure of neoliberal efforts to dismantle the welfare state challenging some tenets of the resilience thesis this article seeks to broaden the discussion of welfare state retrenchment the authors argue that a sharp deceleration of social spending has occurred in most oecd countries since 1980 that welfare states have failed to offset the rise of market generated inequality and insecurity and that welfare programs have become less universalistic they stress the distributive and political consequences of market oriented reforms of the public sector

financial innovation price smoothing and monetary policy financial innovation price smoothing and monetary policy i introduction in a monetary economy the volume of nominal transactions fluctuates with the level of economic activity empirical evidence suggests that the supply of nominal transaction assets such as currency and bank deposits also fluctuates with the level of economic activity some researchers have attributed these observations to the phenomenon of money endogeneity 1 one explanation for this endogenous supply response is a systematic monetary policy as described by black 1972 under which the central bank passively adjusts the money supply to accommodate the changes in money demand alternatively king and plosser 1984 and saving 1979 stress the role of the private banking system in producing this endogenous response they argue that exogenous changes in real activity elicit sympathetic changes in the demand for transaction services that may be partially or fully accommodated by the banking system through its supply of inside money in either case this endogenous supply response tends to mitigate the price adjustment that accompanies a real supply shock 2 in the long run however the price level is ultimately determined by the central bank in the market for the nominal quantity that it controls e g currency bank reserves when deposit accounts are subject to reserve requirements or the monetary base 3 this suggests that if the private banking system does not fully accommodate the real shock and if the shock exhibits a well defined persistence then endogenous price adjustments that are fully anticipated may be further damped by a passive supply response by the central bank in addition if price expectations affect real interest rates then current period price level smoothing via a passive monetary policy may also be possible 4 in addition to employing transaction assets currency and checkable bank deposit accounts to meet their transaction requirements agents may purchase non deposit transaction services directly for firms these services include the tools available to the modern corporate cash manager such as lockbox collection systems repurchase agreements and zero balance accounts in the household sector they take the form of atms debit and credit cards and overdraft privilages on checkable accounts among others these non deposit transaction services represent an increasingly important medium of exchange their supply by the banking system is not directly controlled by the central bank and also offers another avenue by which the economy may respond endogenously to fluctuating transaction requirements associated with real shocks thereby further mitigating the price adjustment 5 the production of non deposit transaction services is subject to technology shocks in the form of financial innovations these innovations alter the economy wide demand for currency and checkable bank deposit accounts and prices adjust as with the introduction of new technology into the production of goods financial innovations are not fully adopted immediately due to the fixed costs of adjusting individual cash management practices but are instead assimilated over time this implies that their effects on transaction asset demands persist if the rate of adoption has a forecastable component the central bank can smooth expected prices by passively accommodating these innovations as with aggregate productivity shocks this persistence may also enable the central bank to damp the disturbances to the current period price level that these innovations create through the impact of price expectations on real interest rates this paper examines a non deposit transaction services market in a model economy that is developed in section ii it has the following features transactors can meet their transaction requirements by allocating wealth to currency or to bank deposit accounts that pay a market determined interest rate or by purchasing non deposit transaction services directly at a market determined price

disaggregate stochastic trends in industrial production abstract several industries appear cointegrated at a highly disaggregated level but the cointegration is not sufficient to reduce the system to a single common trend instead the results indicate that ten common trends are present in the industrial production aggregate

aggregate fluctuations and the industry structure of the us economy abstract in a two sector economy changes in intermediate input trade as reflected in cost share fluctuations are key to determining the amplification properties of investment specific and neutral shocks i document that the cost shares of intermediate inputs produced by the investment sector correlate positively with gdp whereas those of inputs produced by the consumption sector correlate negatively with gdp the two sector model of greenwood et al 1988 is extended to allow for trade of intermediate goods and to show that the documented correlations discipline heterogeneous elasticities of substitution in intermediate inputs across sectors shock amplification that is the effect of a sectorial shock on aggregate value added depends on the degree of heterogeneity in these elasticities of substitution for a calibrated economy to that of the united states i find that shock amplification is stronger than in a unitary elasticity economy it is also stronger than in an economy with a common non unitary elasticity that is either inferred from data via reduced form estimates or calibrated to match the same targets as our benchmark economy

the workweek of capital and its cyclical implications abstract the neoclassical growth model studied in the kydland and prescott time to build paper is modified to permit the capital utilization rate to vary the effect of this modification is to increase the amplitude of the aggregate fluctuations predicted by theory as the equilibrium response to technological shocks if following solow the changes in output not accounted for by changes in the labor and tangible capital inputs are interpreted as being the technology shocks the statistical properties of the fluctuations in the postwar united states economy are close in magnitude and nature to those predicted by theory

real business cycles in this paper we demonstrate how certain very ordinary economic principles lead maximizing individuals to choose consumption production plans that display many of the characteristics commonly associated with business cycles our explanation is entirely consistent with i rational expectations ii complete current information iii stable preferences iv no technological change v no long lived commodities vi no frictions or adjustment costs vii no government viii no money and ix no serial dependence in the stochastic elements of the environment we also provide a completely worked out example of the type of artificial economy we have in mind the time series properties of the example exhibit some major features of observed business cycles although this type of model may not be capable of explaining all of the regularities in actual business cycles we believe that it provides a useful well defined benchmark for assessing the relative importance of factors e g monetary disturbances

plant level nonconvex output adjustment and aggregate fluctuations in most manufacturing industries plant level output is adjusted along three margins of capacity utilization shiftwork weekend work and closing temporarily down due to the discrete and lumpy nature of these margins only a fraction of plants adjust output in response to shocks in a business cycle model calibrated to establishment level observations these nonconvexities make aggregate output less volatile than when plants can adjust smoothly further the mass of adjusting plants is larger in downturns than in upturns leading to counter cyclical volatility of aggregate output and government policy being slightly more effective in recessions than in expansions
