the role of the trade channel in the propagation of oil supply shocks abstract this paper analyzes when and why idiosyncratic oil supply shocks produce large macroeconomic effects in an analytically tractable two country general equilibrium model we focus on a demand driven mechanism the trade channel which transmits oil shocks across economies through changes in the non oil goods terms of trade when the trade channel is operative we have three main consequences on the transmission of oil shocks first the macroeconomic impact of oil shocks may be large and asymmetric across countries second the magnitude of the effects is nonlinear in the size of the oil shock third terms of trade movements never ensure international risk sharing after an idiosyncratic oil supply shock

capital allocation how the us compares with other major industrialized nations data for the seven major industrialized nations spanning two decades provide evidence that capital formation as a percentage of gross domestic product differs significantly among the major industrialized nations comparatively the us ranks among the leaders in residential structures and among the lowest in commercial structures however us private sector allocation of capital to machinery and equipment appears to be in line with other major trading nations the rate of capital cost recovery appears to affect the amount of capital allocated to commercial structures but not to residential structures or machinery and equipment likewise changes in the capital cost recovery provisions under the economic recovery tax act of 1981 seem to have led to an increase in capital allocated to commercial structures and to a marginal increase in capital allocated to machinery and equipment

is protection for sale evidence on the grossman helpman theory of endogenous protection grossman and helpman 1994 present a theory of endogenous protection by explicitly modeling government industry interactions for which mere black box models previously existed they obtain a ramsey pricing type solution to the provision of protection which emphasizes the role of inverse import penetration ratios and import elasticities on the lobbying side the model makes predictions about lobbying competition and lobbying spending according to deadweight costs from protection the model not only makes for richer theory in terms of rigor and elegance but its predictions are directly testable whether the grossman helman model stands up to real world data is investigated in this paper predictions from both the protection side and lobbying side are tested using cross sectional u s nontariff barrier data we also compare the second generation grossman helpman model with a more traditional specification our results call for serious consideration of this model in the political economy literature

allocative disturbances and specific capital in real business cycle theories chanted albeit in varying degree with business cycle theories that either posit unexplained nominal wage and price rigidities or rely on misperceptions about nominal variables as a key driving force one response to this disenchantment has been a concentration of research effort on real business cycle theories aside from dissatisfaction with competitor theories the very visible oil price shock episodes of the 1970 s lent plausibility to the view that exogenous real disturbances cause large fluctuations in aggregate economic activity this essay on real business cycle theory considers the role of allocative disturbances in aggregate economic fluctuations when human and physical capital are specialized by allocative disturbances i mean events that impinge on the economy by inducing a costly time consuming reallocation of specialized resources at least since the publication of ricardo s principles in 1817 economists have recognized some of the potentially important aggregate consequences of allocative disturbances ricardo writes

are unemployment and out of the labor force behaviorally distinct labor force states this paper tests the hypothesis that the classifications unemployed and out of the labor force are behaviorally meaningless distinctions this hypothesis is rejected distinct behavioral equations govern transitions from out of the labor force to employment and from unemployment to employment the evidence reported in this paper is broadly consistent with versions of search theory in which unemployment is a state that facilitates the job search process in an appendix we demonstrate that log concavity of the wage offer distribution implies that the exit rate from unemployment is an increasing function of the rate of arrival of job offers

the asymmetric impact of oil prices interest rates and oil price uncertainty on unemployment in the us abstract in this study we investigate the presence of asymmetric interactions between oil prices oil price uncertainty interest rates and unemployment in a cointegration framework utilizing the nonlinear auto regressive distributed lag nardl approach we show the asymmetric responses of unemployment to changes in oil prices oil price uncertainty and interest rates in the long run more specifically the results of our analyses suggest that an increase in oil price results in increased unemployment while there is no significant impact of reduced oil prices on the one hand reduced oil price uncertainty leads to a decrease in unemployment whereas an increase in oil price uncertainty does not have an impact we also observe increased unemployment in response to a decrease in interest rates as the impact of increased interest rates is not significant last but not least we find that option implied oil price volatility as a measure of oil price uncertainty outperforms the conditional volatility of crude oil prices in predicting unemployment this study provides valuable implications for policymakers to design sound economic policies

oil price shocks and real gdp growth empirical evidence for some oecd countries this study assesses empirically the effects of oil price shocks on the real economic activity of the main industrialized countries multivariate var analysis is carried out using both linear and non linear models the latter category includes three approaches employed in the literature namely the asymmetric scaled and net specifications evidence of a non linear impact of oil prices on real gdp is found in particular oil price increases are found to have an impact on gdp growth of a larger magnitude than that of oil price declines with the latter being statistically insignificant in most cases among oil importing countries oil price increases are found to have a negative impact on economic activity in all cases but japan moreover the effect of oil shocks on gdp growth differs between the two oil exporting countries in the sample with the uk being negatively affected by an oil price increase and norway benefiting from it

role of oil price shocks on macroeconomic activities an svar approach to the malaysian economy and monetary responses abstract this study examines the impact of oil price uncertainty on malaysian macroeconomic activities and monetary responses we use a structural var svar model based on monthly data over the period 1986 2009 the egarch model estimates show an important asymmetric effect of oil price shocks on the conditional oil price volatility dynamic impulse response functions obtained from the svar model show a prolonged dampening effect of oil price volatility shock on malaysian industrial production we also find that levels of consumer price index cpi decline with a positive shock to oil price uncertainty this is the result of negative demand shock due to the postponement of consumption of big ticket items by individuals households and other sectors of the economy we also found that the malaysian central bank adopts an expansionary monetary policy in response to oil price uncertainty variance decomposition analysis reconfirms that volatility in the oil price is the second most important factor to explain the variance of industrial production after its own shocks these results shed some light on how the central bank of malaysia can use controlling mechanisms to stabilize aggregate output and price level

asymmetries in the responses of regional job flows to oil price shocks this paper studies the effect of oil price innovations on manufacturing job flows across u s states first i estimate a nonlinear structural equation model and compute impulse response functions by monte carlo integration i find asymmetries in the responses of job flows to positive and negative oil price innovations yet these asymmetries do not pass a test of symmetry on the impulse responses especially after accounting for data mining third i use a test for the absence of job reallocation to evaluate whether an unexpected increase in the real price of oil price triggers an important change in job reallocation i find that oil price shocks have limited regional allocative effects

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

sectoral shifts and cyclical unemployment a substantial fraction of cyclical unemployment is better characterized as fluctuations of the frictional or natural rate than as deviations from some relatively stable natural rate shifts of employment demand between sectors of the economy necessitate continuous labor reallocation since it takes time for workers to find new jobs some unemployment is unavoidable this paper presents evidence that most of the unemployment fluctuations of the seventies unlike those in the sixties were induced by unusual structural shifts within the u s economy simple time series models of layoffs and unemployment are constructed that include a measure of structural shifts within the labor market these models are estimated and a derived natural rate series is constructed

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

trends random walks and persistence an empirical study of disaggregated u s industrial production unit root and variance ratio tests are used to examine the trend properties and degree of persistence of industrial production in u s industries and comparable aggregates during the post world war ii period the evidence from unit root tests suggests that less than one half of these industries have output that may be characterized as a random walk the variance ratio test results generally support this conclusion consistent with standard economic theory fluctuations in durable goods industries are less persistent than in nondurable goods industries finally tests find relatively greater persistence in the aggregate industrial production data copyright 1992 by mit press

energy price shocks household location patterns and housing crises theory and implications abstract the u s housing collapse in 2007 is widely blamed for inducing a financial crisis that spread to the real economy and caused a severe and prolonged downturn this paper develops a model to investigate the role of gasoline price shocks in triggering the housing market collapse and identifies a new channel through which energy price shocks affect the financial market and the macro economy results suggest that unanticipated gasoline price shocks increase the cost of work commutes lower the value of homes away from the city center and increase foreclosure rates as homeowners either cannot afford mortgage payments amid elevated gas expenditures or seek to abandon underwater homes the model predicts that gasoline price shocks disproportionately affect suburban households that face greater exposure due to longer commutes and lower incomes empirical evidence from the 2007 08 housing collapse is presented to corroborate this theory

asymmetries in the response of economic activity to oil price increases and decreases abstract it has been common to assume that the relationship between economic activity and oil prices is asymmetric theoretical underpinnings for this asymmetry include costly sectoral reallocation partial equilibrium models of irreversible investment and some version of precautionary savings yet recent studies that use new methodologies to test for asymmetries in u s data have cast some doubts on that premise in this paper we use state of the art techniques to evaluate the presence of asymmetries for a set of oecd countries containing both oil exporters and oil importers we find very little support for the hypothesis that the response of industrial production to oil price increases and decreases is asymmetric our results have important implications for theoretical models of the transmission of oil price shocks they point towards the importance of direct supply and direct demand transmission channels as well as indirect transmission channels that imply a symmetric response

capital allocative disturbances and economic fluctuations permanent sector specific productivity shocks alter the relative marginal products of capital and labor across sectors such that the existing factor allocations are suboptimal the subsequent factor reallocations may involve the costly movement and redeployment of capital and labor across sectors to proxy the magnitude of these disturbances this paper focuses on capital rather than labor allocative disturbances since firms can make temporary adjustments in employment levels in response to transitory sectoral shocks empirical evidence is provided that these costs reduce output from what it otherwise would have been and that this effect persists for up to three quarters copyright 1993 by mit press

aggregation and irrelevance in multi sector models abstract this paper studies the ability of input output relationships to generate fluctuations in aggregate output in several multi sector models including that of long and plosser 1983 in these models the manufacture of each sector s output depends on other sectors for materials these interconnections provide a mechanism for transmission of shocks across sectors and over time we ask how aggregates from these multi sector models behave relative to single sector models we provide conditions under which the second moment properties of aggregates in these models are the same as their single sector counterparts we further demonstrate that a broad class of input output structures generate aggregates with identical second moment properties and that the input output structures in this class provide a poor amplification mechanism for sector shocks

the effects of oil price shocks on job reallocation we investigate the effect of oil price innovations on u s manufacturing job flows using a simultaneous equation model that nests symmetric and asymmetric responses we find no evidence of asymmetry in the response of job flows to positive and negative oil price innovations we then inquire whether firms when facing positive shocks shed jobs faster than they create jobs we show that positive innovations lead to a decline in net employment and an increase in job reallocation possibly due to search and matching issues yet the latter effect becomes statistically insignificant when we control for data mining we demonstrate that the cumulative one year effect of oil price shocks on job creation and destruction was smaller during the great moderation but it was larger for gross job reallocation these variations were caused by a change in the transmission channel and not by smaller oil price shocks

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

oil price uncertainty in canada bernanke bernanke ben s irreversibility uncertainty and cyclical investment quarterly journal of economics 98 1983 85 106 shows how uncertainty about energy prices may induce optimizing firms to postpone investment decisions thereby leading to a decline in aggregate output elder and serletis elder john and serletis apostolos oil price uncertainty http ssrn com abstract 908675 2009 find empirical evidence that uncertainty about oil prices has tended to depress investment in the united states in this paper we assess the robustness of these results by investigating the effects of oil price uncertainty in canada our results are remarkably similar to existing results for the united states providing additional evidence that uncertainty about oil prices may provide another explanation for why the sharp oil price declines of 1985 failed to produce rapid output growth impulse response analysis suggests that uncertainty about oil prices may tend to reinforce the negative response of output to positive oil shocks

unemployment and vacancies with sectoral shifts recent analyses of unemployment vacancy series suggest that aggregate shocks rather than sectoral shocks are the primary factors responsible for unemployment fluctuations this inference follows from two widely held beliefs sectoral shocks induce only positive unemployment vacancy comovements while negative comovements are necessarily the result of aggregate demand shocks this paper describes an equilibrium matching model that identifies plausible circumstances in which neither assumption is correct thus suggesting that unemployment vacancy data are inconclusive interestingly this model s novel results are due to standard features in the contracting literature firms experience relative price shocks and negotiate contracts that prescribe temporary layoffs copyright 1994 by american economic association

the economics of special interest politics the case of the tariff this paper investigates the interaction of politicians and special interest lobbies the goal is to model the equilibrium levels of redistributive policies such as taxes subsidies tariffs and regulatory decisions the model is applied throughout to the setting of tariffs by contributing to political campaigns special interest lobbies generate economic returns higher tariffs generate revenue for import competing industries through higher product prices higher milk support prices raise dairy farm income and so forth the lobby invests to maximize these net economic returns in evaluating their chances of election politicians weigh the favorable effects of special interest money against the unfavorable association with the lobby and the social cost of the redistributive policy section i explores the lobby s problem it describes a formalization of mancur olson s discussion of the voluntary provision of public goods and optimal contributions by lobbies to political campaigns section ii describes determination of the equilibrium tariff positions of each politician in a political campaign

oil price uncertainty and unemployment abstract in this study we empirically search the effects of oil price uncertainty and oil price shocks on u s unemployment rate using a garch in mean var model for the period 1974 q2 2017 q4 based on our findings we show that oil price uncertainty significantly increases unemployment rate in the u s economy likewise our impulse response analysis affirms that a positive oil price shock increases unemployment while the response of unemployment to a negative oil price shock is negative moreover we reveal that unemployment rate reacts to positive and negative shocks asymmetrically more specifically the response of unemployment to negative oil price shocks is negative and slighter in size besides oil price uncertainty is found to magnify the rise in the u s unemployment rate these findings are in keeping with the real options theory which reveals that the uncertainty about goods prices leads firms to postpone or abandon their production and investment and they seem to be robust to the use of different real oil price measures

the economic effects of energy price shocks large fluctuations in energy prices have been a distinguishing characteristic of the u s economy since the 1970s turmoil in the middle east rising energy prices in the u s and evidence of global warming recently have reignited interest in the link between energy prices and economic performance this paper addresses a number of the key issues in this debate what are energy price shocks and where do they come from how responsive is energy demand to changes in energy prices how do consumers expenditure patterns evolve in response to energy price shocks how do energy price shocks affect u s real output inflation and stock prices why do energy price increases seem to cause recessions but energy price decreases do not seem to cause expansions why has there been a surge in the price of oil in recent years why has this new energy price shock not caused a recession so far have the effects of energy price shocks waned since the 1980s and if so why as the paper demonstrates it is critical to account for the endogeneity of energy prices and to differentiate between the effects of demand and supply shocks in energy markets when answering these questions

oil and the macroeconomy when prices go up and down an extension of hamilton s results in an important paper hamilton 1983 demonstrated a strong correlation between oil price changes and gross national product growth in u s data however his study pertained to a period in which all the large oil price movements were upward and thus it left unanswered the question whether the correlation persists in periods of price decline moreover the price variable he used was somewhat distorted by price controls in the 1970s this note investigates whether hamilton s results continue to hold when the sample is extended to include the recent oil market collapse and the oil price variable is corrected for the effects of price controls particular attention is given to the possibility of asymmetric responses to oil price increases and decreases as suggested in the structural employment literature loungani 1986 davis 1987 hamilton 1988 like hamilton i based my investigation on the gnp equation in sims s 1 980b six variable quarterly vector autoregressive model

why special economic zones using trade policy to discriminate across importers tariffs are generally assumed to depend on the product not the identity of the importer however special economic zones are a common economically important policy used worldwide to lower tariffs on selected goods for selected manufacturers i show this is motivated by policymakers desire to discriminate across buyers when a tax is intended to raise prices for sellers through a mechanism distinct from existing theories of optimal taxation using a new dataset compiled from public records and exogenous changes in imports of intermediate goods i find the form composition and size of us zones are consistent with the theory

family income and child outcomes in canada a positive relationship between income and child outcomes has been observed in data from numerous countries a key question concerns the extent to which this association represents a causal relationship as opposed to unobserved heterogeneity we use data from the national longitudinal survey of children and youth to implement a series of empirical strategies for estimating the existence and size of the effect of income on three measures of cognition our results indicate that the effect of income on these outcomes may well be positive but that it is likely to be smaller than conventional estimates jel classification i10 revenu des familles et comportement des enfants au canada il existe une relation positive entre le revenu des familles et les comportements des enfants dans les releves statistiques de nombreux pays une question centrale demeure jusqu a quel point est ce que cette correlation represente une relation causale par opposition a du bruit les auteurs utilisent l enquete longitudinale nationale sur les enfants et les jeunes elnej pour mettre en place une serie de strategies empiriques pour calibrer l existence et la taille de l effet de revenu sur trois mesures de cognition les resultats montrent que l effet de revenu sur ces comportements peut fort bien etre positif mais qu il est vraisemblablement plus faible que ce que suggerent les evaluations conventionnelles

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

sectoral shocks and business cycles a disaggregated analysis of output fluctuations in the uk in this paper we first show that it is possible to modify linear real business cycle models to allow for disaggregate industry specific factors in the generation of macroeconomic fluctuations we then try to determine the relative importance of aggregate and sectoral shocks by doing principal components analysis on the residuals from a var of output growth rates in 19 uk industrial sectors we find that a significant percentage of the innovations in sectoral output growths can be accounted for by a single unobserved component however since the model only sets an upper bound to the explanatory power of aggregate impulses the importance of using sectoral data to extract additional information to bear on the analysis of economic fluctuations is confirmed by our findings

oil price shocks and transportation firm asset prices abstract the transportation sector is a major user of oil based energy even as oil prices continue to fluctuate greatly the impact of oil price changes on transportation firms has heretofore not been adequately examined this paper fills this gap documenting important new findings based on analysis of over two decades of daily data on large changes in oil prices oil price shocks first while transportation firm returns are influenced negatively by oil price increases risks are increased more by oil price declines second firm characteristics are important with the market to book ratio being the most important firm characteristic and roa firm size and the prior run up in prices are also important in influencing oil price related returns betas variances and trading volumes third in the s p transportation sub sector industry concentration is negatively related to returns oil price risk and trading volume and asymmetrically related to returns and market betas these new findings enhance our understanding of the asset price impact of oil price shocks and should be of much interest to scholars corporate executives money managers regulators and policy makers
