what determines the duration of a fiscal consolidation program abstract this paper assesses the determinants of the length of fiscal consolidation using annual data for 17 industrial countries over the period 1978 2009 relying on a narrative approach to identify fiscal consolidation episodes we show that fiscal variables such as the budget deficit and the level of public debt and economic factors such as the degree of openness the inflation rate the interest rate and per capita gdp are crucial for the fiscal consolidation process additionally we employ duration analysis over a set of consolidation spells and find that as time goes by the likelihood of a fiscal consolidation ending is higher however the hazard function is not monotonic indeed it increases until the eighth or ninth year and starts decreasing afterwards we also find that i spending driven consolidations are shorter than tax driven consolidations ii both types of consolidation are longer in non european countries than for european countries and iii the size of the consolidation program in percentage of gdp does not significantly affect duration all in all our results support the importance of cuts in government spending as a way of bringing economies into a sustainable path for public debt moreover they highlight the role played by a fiscal framework that imposes discipline in governments as a device to credibly shorten the length of fiscal consolidation episodes

commodity price responses to monetary policy surprises commodity prices are important both as a source of shocks and for the propagation of shocks originating elsewhere in the economy many vector autoregression var studies estimate a gradual response of commodity prices to monetary policy shocks exploiting information in high frequency financial market data and using the methods of rigobon and sack 2004 i find that a 10 basis point surprise change in interest rates causes commodity prices to fall immediately by about 0 5 this is about two thirds of the estimated response of the s p500 and about five times larger than the response in a var 12 months after the shock metals prices tend to respond more than agricultural commodities the point estimate for oil prices is similar to other commodities but is estimated imprecisely

us monetary policy and sectoral commodity prices abstract using a structural var svar model we examine the effects of the monetary policy of the united states on sectoral commodity prices including the non fuel commodity prices food prices beverage prices prices of agricultural raw materials prices of metals and prices of fuel energy commodities and macroeconomic activity the empirical evidence suggests that a u s monetary contraction leads to an immediate rise in the broad commodity price index which possibly reflects an aggregation bias greater expected inflation and speculation high production costs or some overshooting due to overreactions then the response erodes after six quarters as the positive interest rate shock vanishes and higher interest rates and liquidity drainage take traction despite this the aggregate price response masks the existence of significant heterogeneity in the price responses of the different types of commodity sectors more specifically a positive interest rate shock leads to i an initial pop in the price returns of the non fuel commodities which later reverses path and becomes negative as in the case of the prices of agricultural raw materials ii a positive and persistent rise in the volatile food prices iii a fall in the beverage prices and iv a persistent reduction in the prices of metals and the prices of energy prices our results also remain globally intact with respect to alternative specifications and identification schemes as well as to unconventional monetary policy effects similar results are also found when commodity futures prices are used we conclude that policymakers should recognize the source of sector inflation before embarking on contractionary monetary policy the design of core inflation targeting is also preferable to headline inflation targeting

government purchases and real interest rates this paper examines the dynamic impact of government purchases in a simple general equilibrium model with both durable and nondurable consumer goods as well as productive capital the model generates perhaps surprising results in particular increases in government purchases are shown to cause reductions in real interest rates the model thus provides a possible explanation for the observed behavior of real interest rates around wars copyright 1987 by university of chicago press

the effects of monetary policy in a small open economy the case of portugal in this article i analyse the macroeconomic effects of monetary policy on the portuguese economy i show that a positive interest rate shock leads to i a contraction of real gdp and a substantial increase of the unemployment rate ii a quick fall in the commodity price and a gradual decrease of the price level and iii a downward correction of the stock price index it also produces a short lived liquidity effect and helps explain the negative comovement between bonds and stocks in addition i find evidence suggesting the existence of a money demand function characterized by small output and interest rate elasticities by its turn the central bank s policy rule follows closely the dynamics of the money markets finally both the real gdp and the price level in portugal would have been higher during almost the entire sample period if there were no monetary policy surprises

liquidity and the dynamic pattern of asset price adjustment a global view abstract global liquidity expansion has been very dynamic since 2001 contrary to conventional wisdom high money growth rates have not coincided with a concurrent rise in goods prices at the same time however asset prices have increased sharply significantly outpacing the subdued development in consumer prices we investigate the interactions between money and goods and asset prices at the global level using aggregated data for major oecd countries our var results support the view that different price elasticities on asset and goods markets explain the observed relative price change between asset classes and consumer goods

spillovers from the oil sector to the housing market cycle we assess the spillovers from the oil sector to the housing market cycle using quarterly data for 20 net oil exporting and importing industrial countries and employing continuous and discrete time duration models we do not uncover a statistically significant difference in the average duration of booms and normal times in the housing markets of those net oil importers and net oil exporters similarly the degree of exposure to commodity price fluctuations does not seem to significantly affect the housing market cycle however we find that housing booms are shorter when oil prices increase than housing busts when oil prices decrease we also show that the net oil importers are more vulnerable to protracted housing slump episodes than the net oil exporters

fiscal policy and the term structure of interest rates an intertemporal optimizing analysis the effects of government expenditure on the dynamic evolution of the term structure of interest rates are analyzed in an infinite horizon intertemporal optimizing macroeconomic framework three types of disturbances are discussed unanticipated and anticipated permanent increases and a temporary decrease in the case of anticipated future and temporary disturbances the lead time in the former and the duration in the latter are critical determinants of the dynamics for a very temporary shock the short term and long term rates will diverge in the short run while most of the analysis focuses on infinitesimally short and infinitely long bonds the dynamics of the entire yield curve are also considered copyright 1992 by ohio state university press

housing markets consumption and financial liberalisation in the major economies abstract this paper analyses the implications of relaxing credit restrictions in housing finance markets a theoretical model of the interaction of financial and housing markets and forward looking agents is developed the effects of financial liberalisation in the model are analysed and evidence from the u s a and u k on the impact of easing credit restrictions is presented estimates are also made of the degree to which credit restrictions may bind on households in those countries where the range of mortgage products on offer is still more limited than in the u k and u s a simulations are undertaken to gauge the effect on consumption saving and bequests of wealth of possible future convergence in national systems of housing finance

why are crude oil prices high when global activity is weak abstract there have been substantial increases in liquidity in recent years and real oil prices have almost returned to the high levels achieved before the global financial crisis unanticipated increases in global real m2 led to statistically significant increases in real oil prices the historical impact of global real m2 on the real price of crude oil is important in the recovery of oil prices over 2009 to 2011

the role of commodity prices in formulating monetary policy commodity prices often provide signals about the future direction of the economy especially inflation it has been argued therefore that the information in commodity prices should be used in formulating monetary policy this paper investigates whether a systematic monetary policy response to contemporaneous commodity price shocks would have helped stabilize the postwar u s economy the authors findings suggest that responding to unexpected commodity price movements would have lowered the average rate of inflation and reduced its variability while the path of real growth would be relatively unchanged copyright 1991 by mit press

government spending and private consumption this paper investigates the macroeconomic effects of anticipations about future fiscal expenditures within a simple perfect foresight general equilibrium model this paper extends s djajic 1987 by investigating an anticipated permanent increase in government spending an anticipated permanent increase may temporarily stimulate capital accumulation the questions of whether anticipated or unanticipated changes in government spending have a larger effect on capital accumulation and output is related to the questions of whether government spending is initially above or below the optimal level

metal volatility in presence of oil and interest rate shocks abstract this study uses three two factor volatility models of the garch family to examine the volatility behavior of three strategic commodities gold silver and copper in the presence of crude oil and interest rate shocks the results of the standard garch models suggest that gold and silver have almost the same volatility persistence which is greater than that of copper the cgarch estimates indicate that the short run transitory component of volatility converges to zero much faster for copper than for gold and silver in this sequence however the permanent volatility component demonstrates equally strong persistence in the long run for all three metals the egarch results suggest that the leverage effect is present and significant for copper only implying that gold and silver can be good investment in anticipation of bad times past oil shock does not impact all three metals similarly monetary policy and to leaser extent the oil shocks have calming effects on precious metals but not on copper if the t bill rate is used crises such as the 2003 iraq war heighten metal volatility these results have implications for derivatives valuations using gold as a reserve asset risk analysis and for the commodity exporting countries and commodity producing firms

the uk consumption boom of the late 1980s aggregate implications of microeconomic evidence two competing explanations of the uk consumer boom in the late 1980s are the financial liberalisation imperfect housing market hypothesis of muellbauer and murphy and the expectations hypothesis of king we use 15 years of family expenditure surveys and cohort analysis to investigate to what extent these two hypotheses agree with observed changes in consumption patterns we find that the housing markets explanation accounts for much of the increase by older cohorts but cannot be reconciled with the marked rise in expenditure levels of younger households a simple simulation exercise shows instead that the expectations hypothesis can generate increases of expenditure by young consumers of the magnitude observed in our data

oil prices and global factor macroeconomic variables abstract this paper investigates the relationship between oil prices global industrial production prices central bank policy interest rate and monetary aggregate with a global factor augmented error correction model we confirm the following stylized relationships i at global level money industrial production and prices are cointegrated ii positive innovation in global oil price is connected with global interest rate tightening iii positive innovation in global money price level and industrial production is connected with an increase in oil prices iv positive innovations in global interest rate are associated with a decline in oil prices and v the u s euro area and china are the main drivers of global macroeconomic factors

the macroeconomic effects of fiscal policy we investigate the macroeconomic effects of fiscal policy using a bayesian structural vector autoregression b svar approach we identify fiscal policy shocks via a partial identification scheme but also i include the feedback from government debt ii look at the impact on the composition of output iii assess the effects on asset markets iv use quarterly data and v analyse empirical evidence from the us the uk germany and italy the results show that government spending shocks in general have a small effect on gross domestic product gdp lead to important crowding out effects have a varied impact on housing prices and generate a quick fall in stock prices government revenue shocks generate a mixed effect on housing prices and a small and positive effect on stock prices the empirical evidence also suggests that it is important to explicitly consider the government debt dynamics in the model

government spending and the optimal rates of consumption and capital accumulation this paper investigates the effects of a temporary change in government expendit ure on private consumption and investment the model employed is one of a closed economy populated by infinitely lived utility maximizing individuals the analysis focuses on the implications of alternative assumptions concerning the relationship between public and private c onsumption in the household s utility function a temporary increase in government expenditure is found to reduce investment if public and private goods are edgeworth complements or independent however if they are substitutes there exists the possibility of an increase in investment

government spending endogenous labor and capital accumulation following turnovsky and fisher 1995 journal of economic dynamics and control 19 747 786 we reexamine the dynamic responses of the capital stock to an unanticipated temporary increase in government consumption and infrastructure expenditures the key factors determining capital accumulation are endogenous labor the duration of policy expansion and the relationship between private decisions and the composition of public expenditure given that private decisions and public consumption are edgeworth independent if employment is variable investment increases with the duration of fiscal expansion following a temporary public infrastructure expansion there always exists the possibility of a decrease in investment before the fiscal reversion under fixed employment however a temporary public infrastructure expansion under variable employment leads to a likely increase in investment before the fiscal reversion

monetary policy shocks and the dynamics of agricultural commodity prices evidence from structural and factor augmented var analyses fluctuation in commodity prices is a significant and timely issue to be studied this study is to examine the impact of monetary policy and other macroeconomic shocks on the dynamics of agricultural commodity prices the major contributions of this study are twofold first unlike other studies that use indexes this study analyzes the commodities individually affording the inclusion of commodity specific fundamentals such as the level of inventory an important determinant of commodity price in a structural var framework second it exploits a rich data set of agricultural commodity prices which includes commodities that are usually overlooked in the literature and extracts a common factor using the dynamic factor model to understand the extent of comovement of the prices and to gauge the extent to which macroeconomic shocks drive the comovement in a factor augmented var favar framework the findings show that monetary policy global economic conditions and the u s dollar exchange rates play an important role in the dynamics of agricultural commodity prices

a life cycle consistent empirical model of family labour supply using cross section data this paper estimates a utility maximising model of the joint determination of male and female labour supplies using a sample of married couples from the u k family expenditure survey the emphasis is on the estimation of within period preferences that are consistent with intertemporal two stage budgeting under uncertainty however the approach we adopt provides an alternative method of estimating certain aspects of life cycle behaviour to the fixed effects constant approach of heckman and macurdy 1980 macurdy 1981 and browning deaton and irish 1985 moreover it relaxes some of the underlying restrictions that are implicit in these constant models under uncertainty

monetary policy and food inflation in south africa a quantile regression analysis abstract although optimal monetary policy stabilizes food inflation theoretically empirical studies remain limited not only in the context of volumes and the estimation approaches but are focused on selected advanced and emerging countries to the neglect of africa where poverty and dominance of food in the consumption basket are more pronounced we provide empirical evidence in the context of south africa using quantile regressions rising food prices are destabilized even further by restrictive monetary policy a finding that has ramifications for inflation targeting especially given that a quarter of the country s population is food poor

the impact of uncertainty shocks on the volatility of commodity prices in this paper we empirically examine the impact of uncertainty shocks on the volatility of commodity prices using several alternative measures of economic uncertainty for the u s we estimate their effects on commodity price volatility through var analysis we find that the latent uncertainty shocks have the most significant impact on commodity price volatility when compared to observable measures of economic uncertainty in specific our results show that the unobservable economic uncertainty measures of jurado et al 2015 have a significant and long lasting positive effect on the volatility of commodity prices our findings indicate that a positive shock in unobservable macroeconomic and financial uncertainty leads to a persistent increase in the volatility of the broad commodity market index and of individual commodity prices with the macroeconomic effect being more significant finally we show that the impact is stronger in energy commodities compared to agricultural and metals markets

deterioration of the terms of trade and capital accumulation a reexamination of the laursen metzler effect abstract this paper analyzes the effect of both a permanent and a temporary deterioration in the terms of trade on a small open economy the model based on intertemporal optimization emphasizes the labor leisure choice and the role of capital accumulation the transitional dynamics is shown to depend upon the long run response of the capital stock to the terms of trade shock this consists of a negative substitution effect together with a positive income effect whether or not the laursen metzler effect holds depends upon whether the income effect dominates the substitution effect

is the uk balance of payments sustainable the uk current account deficit john muellbauer and anthony murphy the uk has a large and persistent current account deficit policy makers argue that the deficit is easily financed temporary and therefore not a sign of structural weakness we examine the conditions in which it is appropriate for a country to overspend its current income with the intention of repaying loans out of future income these include an increase in international capital mobility larger net holdings of foreign assets and expectations of faster productivity growth all three apply to the uk so official reasoning is in part correct even so for several decades there has been a trend deterioration of uk trade performance most markedly in manufacturing and we detect no underlying improvement in the 1980s we highlight structural deficiencies in both demand and supply on the demand side we show the importance of rising house prices and easier consumer credit in fuelling the consumer boom to an unwarranted extent this we trace to unjustifiable subsidies to house ownership on the supply side we stress vastly inadequate investment in skill formation education and physical capital these structural deficiencies lead us to a less optimistic view than official policy we draw the policy lessons for the uk and consider whether continental europe will face similar problems as financial markets are liberalized

is there a role for commodity prices in the design of monetary policy some empirical the consumer price index in the united states follows a non trend stationary stochastic process that describes the index as drifting randomly upward without bound monetarists have long pointed to similar properties in the time series of monetary aggregates as the source of this incipient inflation their solution to this problem is close adherence by the central bank to targets for a monetary or reserve aggregate that correspond to slow and steady monetary growth with any periods of excessive monetary growth subsequently offset this would produce monetary series that are trend stationary if the demand for money is reasonably stable price series would also become trend stationary and for properly chosen targets the price level would be bounded with a mean inflation rate of zero

identifying sources of macroeconomic and exchange rate fluctuations in the uk abstract using quarterly data for the period 1985 1 2011 1 this paper uses a stylised open economy structural var model to identify the types of shocks responsible for macroeconomic fluctuations in the uk economy the stylised model implies a set of short run restrictions that allow for the identification of the shocks the importance of each shock is determined by examining forecast error variance decompositions impulse response functions and implied long run or permanent effects the results presented here imply that two shocks called the technology and is shocks are relatively more important than other shocks monetary shocks do exhibit long run monetary neutrality but clearly monetary policy is not responsible for a meaningful share of output and employment fluctuations during the sample period the estimated var and structural disturbances imply that the model accurately reflects the uk economy there is little evidence of a price puzzle or an exchange rate puzzle evidence against uncovered interest rate parity in response to an unexpected monetary policy tightening

oil and the macroeconomy since the 1970s economists have long been intrigued by empirical evidence that suggests that oil price shocks may be closely related to macroeconomic performance this interest dates back to the 1970s the 1970s were a period of growing dependence on imported oil unprecedented disruptions in the global oil market and poor macroeconomic performance in the united states thus it was natural to suspect a causal relationship from oil prices to u s macroeconomic aggregates since then a large body of work has accumulated that purports to establish this link on theoretical grounds and to provide empirical evidence in its support we do not attempt a comprehensive survey of this literature but rather provide an idiosyncratic synthesis of what we view as the key issues in this debate and the insights gained over the last 30 years the timing seems right for such an account although the experience of the 1970s continues to play an important role in discussions of the link between oil and the macroeconomy there have been a number of new oil price shocks since the 1970s notably the 1986 collapse of oil prices and the 2000 boom in oil prices as well as the oil price increases associated with the 1990 1991 gulf war and the 2003 iraq war given this richer case history we are arguably in a better position than two decades ago to distinguish the idiosyncratic features of each oil crisis from the systematic effects increases in oil prices have been held responsible for recessions periods of excessive inflation reduced productivity and lower economic growth in this paper we review the arguments supporting such views first we highlight some of the conceptual difficulties in assigning a central role to oil price shocks in explaining

booms busts and normal times in the housing market we assess the existence of duration dependence in the likelihood of an end in housing booms busts and normal times using data for 20 industrial countries and a continuous time weibull duration model we find evidence of positive duration dependence suggesting that housing market cycles have become longer over the last decades then we extend the baseline weibull model and allow for the presence of a change point in the duration dependence parameter we show that positive duration dependence is present in booms and busts that last less than 26 quarters but that does not seem to be the case for longer phases of the housing market cycle for normal times no evidence of change points is found finally the empirical findings uncover positive duration dependence in housing market booms of european and non european countries and housing busts of european countries in addition they reveal that while housing booms have similar length in european and non european countries housing busts are typically shor

the price effects of monetary shocks in a network economy abstract empirical evidence shows monetary shocks have two temporary effects on the distribution of prices one the dispersion of cross section of prices increases in response to monetary shocks two some prices change in the wrong direction some prices decrease in response to positive monetary shocks and increase in response to negative monetary shocks we present a model that generates the two effects of monetary shocks on the distribution of prices as an out of equilibrium phenomena firms are related to each other through a production network monetary shocks change the working capital of a subset of firms and percolate to other firms through buyer seller linkages price dispersion increases because the percolation of a monetary shock through the production network causes prices to differentially deviate from their steady state values some prices change in the wrong direction because a shift in one firm s demand causes a shift in another firm s supply and vice versa thereby generating complicated chains of bi directional price changes monetary shocks can significantly disturb relative prices even when all prices are fully flexible

government purchases and real interest rates with endogenous time preference abstract the observation of low real interest rates during periods of high temporary government purchases such as wars can be reconciled with the neoclassical growth model extended to allow for endogenous time preference temporary increases in government purchases lead to a fall in the instantaneous rate of time preference this may result in rising investment and falling real interest rates along an adjustment path

option implied expectations in commodity markets and monetary policy abstract in this paper we estimate the dynamic interactions between option implied variance and skewness in agricultural commodity markets and monetary policy using a structural vector autoregressive svar framework we find that an expansionary contractionary monetary policy upwardly downwardly revises commodity markets expectations about the price and volatility path of agricultural products on the other hand our empirical analysis reveals that monetary policy does not have a systematic and timely response to sudden changes in option implied expectations of commodity investors in addition we provide empirical evidence showing the robust forecasting power of agricultural option implied information on monetary policy with r 2 values reaching almost 52

the effects of taxes and dividend policy on capital accumulation and macroeconomic behavior abstract this paper analyzes the macrodynamic effects of changes in various tax rates in an intertemporal optimizing framework two aspects emphasized include the role of dividend policy and the behavior of the stock market both permanent and temporary tax changes are considered with the transitional adjustment paths being characterized in detail the contrast between the short run and long run effects is highlighted in particular an increase in any of the tax rates will cause short run employment to fall and with the capital stock fixed instantaneously the capital labor ratio immediately rises over time as the capital stock declines the capital labor ratio falls

u s equity and commodity futures markets hedging or financialization abstract in this paper we investigate the hedging versus the financialization nature of commodity futures vis a vis the equity market using a arma filter based correlation approach our results suggest that while gold futures are typically seen as a hedge against unfavorable fluctuations in the stock market the majority of commodity futures appears to be treated as a separate asset class in line with their increasing financialization our results are robust to the presence of inflation highlight the hedging role played by fuel energy commodity futures in the nineties and reveal that the commodity financialization boosted since the 2000s we also show that gold futures are partially a safe haven for equity investments in the short term but not in the mid term finally we uncover some hedging financialization of crude oil futures associated to global demand oil supply shocks

an investigation of the effect of monetary factors on agriculture abstract this paper uses an econometric model to assess some of the effects of macro monetary factors on u s agricultural markets attention is focused on impacts of decreasing increasing the level of domestic credit on agricultural trade prices inventory accumulation and domestic disappearance results show that tight monetary policy lowers prices and increase demand for domestic agriculture however the upward pressure on the exchange rate seriously deteriorates the position of u s exports in international markets

were there regime switches in u s monetary policy working paper 2004 14 june 2004 abstract a multivariate model identifying monetary policy and allowing for simultaneity and regime switching in coefficients and variances is confronted with u s data since 1959 the best fit is with a model that allows time variation in structural disturbance variances only among models that also allow for changes in equation coefficients the best fit is for a model that allows coefficients to change only in the monetary policy rule that model allows switching among three main regimes and one rarely and briefly occurring regime the three main regimes correspond roughly to periods when most observers believe that monetary policy actually differed and the differences in policy behavior are substantively interesting though statistically ill determined the estimates imply monetary targeting was central in the early 80s but was also important sporadically in the 70s the changes in regime were essential neither to the rise in inflation in the 70s nor to its decline in the 80s jel classification e52 e47 c53 key words counterfactuals lucas critique policy rule monetary targeting simultaneity volatility model comparison i the debate over monetary policy change in an influential paper clarida gali and gertler 2000 cgg presented evidence that us monetary policy changed between the 1970 s and the 1980 s indeed that in the 70 s it was drastically worse they found that the policy rule apparently followed in the 70 s was one that when embedded in most stochastic general equilibrium models would imply non uniqueness of the equilibrium and hence vulnerability of the economy to sunspot fluctuations of arbitrarily large size their estimated policy rule for the later period on the other hand eliminated this indeterminacy these results are a possible explanation of the volatile and rising inflation of the 70 s and of its subsequent decline the cgg analysis has two important weaknesses one is that it fails to account for stochastic volatility us macroeconomic variables and particularly the federal funds rate have gone through periods of tranquility and of agitation with forecast error variances varying greatly from period to period ignoring such variation does not lead to inconsistent estimates of model parameters when the forecasting equations themselves are constant but it strongly biases toward a finding of changed parameters tests of the stability of the forecasting equations the other weakness is that the cgg analysis rests on powerful and implausible identifying assumptions they require that we accept that the response of the monetary authority to expected future inflation and output does not depend on the recent history of inflation money growth or output it is hard to understand why this should be so especially in the 70 s when monetarism was a prominent theme in policy debates congress was requiring reports from the fed of projected time paths of monetary aggregates and financial markets were reacting sensitively to weekly money supply numbers the requirement for existence and uniqueness of equilibrium in dynamic models is that the monetary policy rule show a more than unit response of interest rates to the sum of the logs of all nominal variables that appear on the right hand side of the reaction function if we force a particular measure of expected future inflation to proxy for all the nominal variables that actually appear independently in the reaction function we are bound to get distorted conclusions on the one hand because expected future inflation will be a noisy measure of the full set of nominal influences on policy we might get downward bias in our estimates from the usual errorsin variables effect on the other hand to the extent that expected future inflation like most expected future values shows less variation than current nominal variables we could find a mistaken scaling up of coefficients

commodity prices money surprises and fed credibilit strict monetarist theory in an extreme form holds that excessive money growth or the expectation of future money growth shows up immediately in the rapid inflation of goods prices however it is widely argued that for most goods prices are in fact sticky in the short run and reflect money growth only in the long run if one seeks a sensitive market measure of the perceived looseiless or tightness of monetary policy one must look elsewhere than at the general price level interest rates being determined in quickly adjusting financial markets are free to respond immediately to expectations regarding monetary policy in 1981 and 1982 every friday at 4 10 p m eastern standard time the federal reserve board would announce the money stock for the week ending nine days previously if the announced money stock was different from what the market had been expecting interest rates generally jumped in the same direction clearly they were responding to revisions of the expected future path of the money stock but nominal interest rates are an ambiguous indicator of expectations on the one hand an announced increase in the money stock may be received by the market as indicating a higher

global factors uncertainty weather conditions and energy prices on the drivers of the duration of commodity price cycle phases abstract we investigate the role of global factors in explaining the length of commodity price cycle phases using a continuous time weibull duration model and data for a panel of 33 countries over the period 1980q1 2015q4 we find evidence of increasing constant positive duration dependence for commodity price booms and busts normal time spells global macroeconomic conditions in particular inflation economic policy uncertainty and monetary policy actions significantly affect the duration of all commodity price cycle phases global environmental conditions also impact the duration of commodity price booms with a rise in average temperature rainfall increasing reducing their length a rise in the number of military conflicts around the globe is associated with shorter booms and busts finally we find that a rise in oil prices is linked with longer booms and shorter busts

commodity prices and money lessons from international finance many commodity prices have been falling rapidly recently as of thursday 31 july 1984 the journal of commerce s index for raw industrial materials had declined 10 relative to march and 20 relative to its peak value in 1980 in the current lull between political conventions this counts as something of a hot topic in washington some supply siders like alan reynolds from jude wanniski s firm polyconomics are warning that the large decline in commodity prices is signalling a general deflation throughout the economy and the possibility of widespread defaults reminiscent of the 1930s congressman jack kemp wants the federal reserve board to adopt a monetary policy rule that would automatically expand whenever commodity prices are low as now and automatically contract whenever commodity prices are high as in the late 1970s there has even been talk about embodying such a monetary rule as a plank in the republican party platform in dallas this month seldom before have steel scrap cotton and hides seemed so glamorous my topic today is the determination of the prices of basic commodities everything from agricultural commodities to the gold and other metals so precious to the supply siders

expectations and commodity price dynamics the overshooting model monetary policy has important effects on agricultural commodity prices because though they are flexible other goods prices are sticky this paper formalizes the argument by applying the dornbusch overshooting model a decline in the nominal money supply is a decline in the real money supply in the short run it raises the real interest rate which depresses real commodity prices they overshoot their new equilibrium in order to generate an expectation of future appreciation sufficient to offset the higher interest rate these real effects which vanish in the long run also result from a decline in the money growth rate

the composition of government expenditure and its consequences for macroeconomic performance abstract this paper employs the intertemporal optimizing market clearing framework to compare the effects of government consumption expenditure and government infrastructure expenditure on macroeconomic adjustment and performance particular attention is focused on the time path of the capital stock and its adjustment to both permanent and temporary changes in government expenditure are considered we show how the effects of both forms of government expenditure on economic welfare can be broken down into 1 i a direct crowding out effect and 2 ii a second component which describes the intertemporal tradeoffs between the short run rate of capital accumulation and the resulting change in the capital stock

what do we learn about consumer demand patterns from micro data the aim of this paper is to assess the importance of using micro level data in the econometric analysis of consumer demand to do this we utilize a time series of repeated cross sections covering some 4 000 households in each of 15 years employing a number of different aggregation procedures we conclude that aggregate data alone are unlikely to produce reliable estimates of structural price and income coefficients however once certain aggregation factors as well as trend and seasonal components are included an aggregate model is not necessarily outperformed across all demand equations in terms of forecasting ability jel d12 c52 c31 the purpose of this paper is to develop a complete consumer demand system based on a time series of individual household data and to use it to measure the biases introduced into the study of consumer de mand behavior when aggregate data are used in place of the appropriate microeco nomic data we assess the suitability of ag gregate data through the impact on income and price elasticities and by evaluating the ability of both micro and aggregate based models to forecast aggregate consumer de mand the biases introduced by the use of aggregate data depend upon the way that household characteristics interact with in come and price effects and on departures of demand systems from linearity we explore the structure of microeconomic demand sys tems and the role of household characteris tics in the behavior of consumer demand both for the light this may shed on the pattern of future demands and for the im plications this behavior has for issues of aggregation consumer demand patterns typically found in micro data sets vary considerably across households with different household characteristics and with different levels of income we model this variability by making intercept and slope parameters in the budget share equations of our demand sys tem depend on household characteristics and by allowing for nonlinear total log expenditure terms in fact in theory consistent demand systems it is total ex penditure rather than disposable income that is allocated across goods we find that this general framework leads to a well specified data coherent demand system which is a quadratic extension of the popu lar almost ideal model of angus s deaton and john muellbauer 1980 the micro level estimates are shown to be sensitive to the treatment of endogeneity of total expen diture and to the specification of interaction terms with household characteristics in ad dition this specification is also shown to possess many attractive features for the evaluation of aggregate models

an intertemporal model of saving and investment this paper characterizes a market economy with infinitely long lived consumers and value maximizing firms which face costs of adjustment for capital the temporary equilibrium of this economy is similar to the short run equilibrium of standard macroeconomic models consumption is a function of wealth investment is related to the value of firms equilibrium between aggregate demand and aggregate supply is achieved by the endogenous adjustment of the sequence of current and future interest rates the dynamic behavior of output consumption and investment in this economy is the same as in an optimal growth model with adjustment costs the paper shows this equivalence and then uses it together with the equivalence of taxes to technological shocks to study the dynamic effects of fiscal policy

commodity prices and bric and g3 liquidity a sfavec approach this paper investigates the influence of liquidity in the major developed and major developing economies on commodity prices liquidity is taken to be m2 a novel finding is that unanticipated increases in the bric countries liquidity is associated with significant and persistent increases in commodity prices that are much larger than the effect of unanticipated increases in g3 liquidity and the difference increases over time over 1999 2012 bric liquidity is strongly linked with global energy prices and global real activity whereas g3 liquidity is not the impact of bric liquidity on mineral and metal prices is twice as large as that of g3 liquidity granger casualty goes from liquidity to commodity prices bric and g3 liquidity and commodity prices are cointegrated bric and g3 liquidity and global output and global prices are cointegrated we construct a structural factor augmented error correction sfavec model
