inventories and upstream gasoline price dynamics abstract this paper sheds new light on the asymmetric dynamics in upstream u s gasoline prices the model is based on pindyck s inventory model of commodity price dynamics we show that asymmetry in gasoline price dynamics is caused by changes in the net marginal convenience yield higher costs of marketing and storage lead to rising gasoline prices whereas a drop in these costs lowers gasoline prices the former effect is stronger this indicates asymmetric dynamics we also analyze the asymmetry across the sample by analyzing recursive and rolling regressions

oil price volatility and the asymmetric response of gasoline prices to oil price increases and decreases this paper analyzes the effect of volatility in oil prices on the degree of asymmetry in the response of gasoline prices to oil price increases and decreases several time series measures of the asymmetry between the responses of gasoline prices to oil price increases and decreases and several measures of the oil price volatility are constructed in all models the degree of asymmetry in gasoline prices declines with an increase in oil price volatility the results support the oligopolistic coordination theory as a likely explanation of the observed asymmetry and are not consistent with the standard search theory and the search theory with bayesian updating

causes for an asymmetric relation between the price of crude oil and refined petroleum products we revisit the issue of asymmetries in the relation between the price of crude oil and refined petroleum products in the united states an econometric analysis of monthly data indicates that the asymmetric relation between the price of crude oil and motor gasoline is generated by refinery utilization rates and inventory behavior the asymmetric relation between the price of crude oil and home heating oil probably is generated by contractual arrangements between retailers and consumers together these results imply that price asymmetries may be generated by efficient markets under these conditions there is little justification for policy interventions to reduce or eliminate price asymmetries in motor gasoline and home heating oil markets

fire sales and the financial accelerator abstract during financial turmoil increases in risk lead to higher default foreclosure and fire sales this paper introduces a costly liquidation process for foreclosed collateral and pro cyclical recovery rates in a dynamic stochastic general equilibrium model of the financial accelerator links between endogenous recovery rates risk premia and default risk generate a liquidity spiral magnifying financial accelerator effects we illustrate how collateral liquidation and monetary policy alter the real impact of financial shocks operating through macro financial linkages and the way a government subsidy on collateral liquidity and required liquidity buffers can help dampen the liquidity spiral by shoring up recovery rates

a monetary policy strategy in good and bad times lessons from the recent past we evaluate the ecb s monetary policy strategy against some of the underlying economic features of the eurozone in normal times and during the financial crisis we show that in the years preceding the crisis the ecb s emphasis on monetary indicators and deliberate avoidance of excessive activism were justified by the underlying macroeconomic conditions that the ecb faced in the eurozone and contributed to avoid more volatile patterns of inflation and economic activity after the collapse of financial intermediation in late 2008 the strategy of the ecb was to adopt several non standard policy measures according to our quantitative evaluation of the impact of the main non standard policies decided in october 2008 and in may 2009 which notably did not include entering commitments regarding the future path of the policy rate such measures have significantly contributed to preserving price stability and forestalling a more disruptive collapse of the macroeconomy stephan fahr roberto motto massimo rostagno frank smets and oreste tristani

panel data modelling and the tax spend controversy in the euro zone this article attempts to differentiate between the debatable tax and spend spend and tax fiscal synchronization and institutional separation hypotheses in order to explore empirically the interplay between public expenditures and public revenues in the economic and monetary union emu member states for this purpose panel data models are derived to test the validity of the four hypotheses in emu countries a notable characteristic of this article is that the four hypotheses are tested by dividing emu countries into various subgroups and using disaggregated data for government expenditures and revenues seeking for the robustness of the empirical evidence the panel data methods of generalized two stage least squares gtsls and generalized method of moments gmm are accordingly applied to identify the relationship between public outlays and taxation receipts gtsls and gmm results strongly support the fiscal synchronization hypothesis implying that budget decision making is significantly influenced b

the relationship between energy demand and real gdp growth rate the role of price asymmetries and spatial externalities within 34 countries across the globe abstract the aim of this paper is to empirically explore the relationship between energy demand and real gross domestic product gdp growth and to investigate the role of regional externalities on per capita final energy consumption fec in 34 countries during the period from 2005 to 2013 the paper utilizes a dynamic panel generalized method of moments dpggm approach and spatial econometric techniques in order to analyse the effect of real gdp growth rate on fec through an error correction model ecm and to examine clustered patterns of energy consumption the results show that a the demand is elastic both in the industrial and the household services sectors b electricity and natural gas are demand substitutes c the relationship between real gdp growth rate and per capita energy consumption exhibits an inverted u shape for all the sample countries under scrutiny 34 countries eurozone and eu28 but not for all the employed sectors of the economy d price electricity and gas and gdp growth asymmetries are supported from the employed parametric tests and e distance does not affect per capita fec but economic neighbours have a strong positive effect

the efficiency of the health system in south africa evidence from stochastic frontier analysis the availability of increased resources and the lack of parallel improvement in health status have renewed interest on health system performance particularly where progress towards the millennium development goals has been slow since the political transition in 1994 south africa has consistently invested over eight of its gross domestic product gdp on health but so far returns remain uneven with some localities delivering lower outcomes than others even when they have comparable input levels this study measures the performance of the country s health system following a stochastic production frontier approach results have revealed that eight of the 52 districts in the country had an efficiency score of below 60 and in four of these the score was below 50 technical inefficiency was positively and significantly associated with hiv prevalence and illiteracy rates reported for districts overall mean technical efficiency te in the country was around 80 given this further improvements in he

current real business cycle theories and aggregate labor market fluctuations hours worked and the return to working are weakly correlated traditionally the ability to account for this fact has been a litmus test for macroeconomic models existing real business cycle models fail this test dramatically we modify prototypical real business cycle models by allowing government consumption shocks to influence labor market dynamics this modification can in principle bring the models into closer conformity with the data our empirical results indicate that it does

anticipated and unanticipated effects of crude oil prices and gasoline inventory changes on gasoline prices abstract this paper examines the effect of anticipated and unanticipated changes in oil prices and gasoline inventory on us gasoline prices we estimate empirical responses to anticipated and unanticipated changes in oil prices and gasoline inventory and show that gasoline price adjustments are faster and stronger for anticipated changes in oil prices and inventory levels than for unanticipated changes furthermore this difference is statistically significant we use these findings to evaluate the cost of adjustment hypothesis suggested by borenstein and shephard 2002 we also find that there is an asymmetry in the effect of gasoline inventory on gasoline and oil prices this finding complements a well known result that positive and negative changes in oil prices have asymmetric effect on gasoline prices

a macroeconomic model with a financial sector this paper studies a macroeconomic model in which financial experts borrow from less productive agents we pursue four sets of results i the economy is prone to instability and occasionally enters volatile episodes as volatility spikes agents precautionary motive increases depressing prices even further log linear approximations fail to capture these non linear effects that can cause economies to be significantly depressed for long periods of time ii endogenous risk during volatile episodes increases asset price correlations iii financial experts impose a negative externality on each other and on the labor sector by not maintaining adequate capital cushion and funding structure iv while risk sharing within the financial sector through securitization and derivatives contracts reduces many inefficiencies it can also amlify systemic risks

oil and pump prices testing their asymmetric relationship in a robust way abstract the aim of this study is to provide a novel method to assess whether retail fuel prices respond asymmetrically to changes in the international crude oil prices to do so we consider the whole supply chain we use daily data and we depart from the current practice in the literature that focuses on prices rather we consider the mark ups of both the refineries and retailers hence we show that we first need to assess whether the refineries mark up responds asymmetrically to the international crude oil prices and subsequently whether the retailers mark up shows an asymmetric behaviour relatively to changes in the refined fuel prices focusing in greece as our case study our findings show that greek fuel retailers do not change their mark up behaviour based on changes of the refined fuel price by contrast the asymmetric behaviour is evident in the refineries mark up relatively to changes in the international crude oil prices which is then passed through to the retailers and consumers finally we provide evidence that weekly and monthly data mask any such asymmetric relationship thus we maintain that unless the appropriate data frequency fuel price transformations and the whole supply chain are considered misleading findings could be revealed

an empirical study of credit shock transmission in a small open economy in this paper we identify and estimate the dynamic effects of foreign us and national canadian credit shocks in a small open economy we use standard credit spreads as proxies to the external finance premium our first result suggests that the us and canadian credit spreads contain substantial forecasting power for several measures of the canadian real economic activity especially during the recent financial crisis and its aftermath secondly an adverse us credit shock generates a significant and persistent economic slowdown in canada the national external finance premium rises immediately while interest rates credit aggregates output and employment indicators decline variance decomposition reveals that credit shocks have a sizeable effect on real activity measures leading indicators and credit spreads yet the unexpected shocks in domestic credit spreads are not able to generate any significant dynamic response of the real activity once we control for the us credit market conditions

the empirical role of the exchange rate on the crude oil price formation this paper adopts a novel empirical approach to the crude oil price formation for the purpose of understanding the price reactions of opec member countries to changes in the exchange rate of the us dollar against other major currencies and prices of other members the results are broadly consistent with the view of the absence of a unified opec determined price in the international crude market literature in addition the results also highlight a cross regional dimension of the crude oil market

chained credit contracts and financial accelerators sufficiently high net worth of financial intermediaries fis is considered a necessary condition for financial and macroeconomic stability in this paper we explore why the net worth of fis is important as compared to that of nonfinancial firms using a dynamic general equilibrium model in which both fis and nonfinancial firms rely on costly external debt we find that an exogenous disruption of the fis net worth has a greater aggregate impact than does the same sized disruption of the nonfinancial firms net worth the key reason is that the net worth of the fis in the united states is small jel e22 e44 g21

optimal dynamic capital requirements we characterize welfare maximizing capital requirement policies in a macroeconomic model with household firm and bank defaults calibrated to euro area data we optimize on the level of the capital requirements applied to each loan class and their sensitivity to changes in default risk we find that getting the level right so that bank failure risk remains small is of foremost importance while the optimal sensitivity to default risk is positive but typically smaller than under basel irb formulas when starting from low levels initially both savers and borrowers benefit from higher capital requirements at higher levels only savers are in favour of tighter and more time varying capital charges

dynamic effects of credit shocks in a data rich environment we examine the dynamic effects of credit shocks using a large dataset of u s economic and financial indicators in a structural factor model an identified credit shock resulting in an unanticipate

do gasoline prices respond asymmetrically to crude oil price changes the authors test and confirm that retail gasoline prices respond more quickly to increases than to decreases in crude oil prices among the possible sources of this asymmetry are production inventory adjustment lags and market power of some sellers by analyzing price transmission at different points in the distribution chain the authors attempt to shed light on these theories spot prices for generic gasoline show asymmetry in responding to crude oil price changes which may reflect inventory adjustment effects asymmetry also appears in the response of retail prices to wholesale price changes possibly indicating short run market power among retailers

asymmetric price adjustments in us gasoline markets impacts of spatial dependence on the rockets and feathers hypothesis gasoline retail prices show sometimes wild asymmetric fluctuations over time we explore the impact of spatial dependence on gasoline retail price formation by using for the first time an asymmetr

shocks structures or monetary policies the euro area and us after 2001 abstract the us federal reserve cut interest rates more vigorously in the recent recession than the european central bank did by comparison with the fed the ecb followed a more measured course of action we use an estimated dynamic general equilibrium model with financial frictions to show that comparisons based on such simple metrics as the variance of policy rates are misleading we find that because there is greater inertia in the ecb s policy rule the ecb s policy actions actually had a greater stabilizing effect than did those of the fed as a consequence a potentially severe recession turned out to be only a slowdown and inflation never departed from levels consistent with the ecb s quantitative definition of price stability other factors that account for the different economic outcomes in the euro area and us include differences in shocks and differences in the degree of wage and price flexibility

price adjustments by a gasoline retail chain we use daily data to examine price responses in the swedish gasoline market to changes in the rotterdam spot price exchange rates and taxes the distribution of price adjustments by a leading retail chain for the period january 1980 to december 1996 is symmetric with no small adjustments an error correction model shows that in the short run prices gradually move towards the long run equilibrium in response to cost shocks there is some evidence that also in the short run prices are stickier downwards than upwards prices respond more rapidly to exchange rate movements than to the spot market price our analysis emphasizes that to fully understand price adjustments it is necessary to examine data sets where the sample frequency at least matches that of price adjustments

real exchange rate dynamics revisited a case with financial market imperfections abstract in this paper we investigate the relationship between real exchange rate dynamics and financial market imperfections for this purpose we first construct a new open economy macroeconomics noem model that incorporates staggered loan contracts as a simple form of the financial market imperfections our model with such a financial market friction replicates persistent volatile and realistic hump shaped responses of real exchange rates which have been thought very difficult to materialize in standard noem models remarkably these realistic responses can materialize even with both supply and demand shocks such as cost push loan rate and monetary policy shocks this implies that the financial market development is a key element for understanding real exchange rate dynamics

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

tax evasion investment shocks and the consumption puzzle a dsge analysis with financial frictions recent studies identify marginal efficiency of investment mei shocks as important drivers of the business cycle however dynamic stochastic general equilibrium dsge models struggle to explain macroeconomic comovements between consumption and the key real variables after a mei shock moreover engaging in tax evasion practices is often an answer to financial constraints which have been recognized as important determinants of cyclical fluctuations as well we use a medium scale new keynesian dsge model that combines tax evasion with financial frictions to simulate a mei shock we show that entrepreneurial tax evasion can solve the comovement problem to a fair extent

credit crises money and contractions an historical view abstract the relatively infrequent nature of major credit distress events makes an historical approach particularly useful using a combination of historical narrative and econometric techniques we identify major periods of credit distress from 1875 to 2007 examine the extent to which credit distress arises as part of the transmission of monetary policy and document the subsequent effect on output using turning points defined by the harding pagan algorithm we identify and compare the timing duration amplitude and co movement of cycles in money credit and output regressions show that financial distress events exacerbate business cycle downturns both in the 19th and 20th centuries and that a confluence of such events makes recessions even worse

optimal interest rate smoothing this paper considers the desirability of the observed tendency of central banks to adjust interest rates only gradually in response to changes in economic conditions it shows in the context of a simple model of optimizing private sector behaviour that assignment of an interest rate smoothing objective to the central bank may be desirable even when reduction of the magnitude of interest rate changes is not a social objective in itself this is because a response of policy to irrelevant lagged variables may be desirable owing to the way it steers private sector expectations of future policy

econometric models of asymmetric price transmission abstract in this paper we review the existing empirical literature on price asymmetries in commodities providing a way to classify and compare different studies that are highly heterogeneous in terms of econometric models type of asymmetries and empirical findings relative to the previous literature this paper is novel in several respects first it presents a detailed and updated survey of the existing empirical contributions on price asymmetries in the transmission mechanism linking input prices to output prices second this paper presents an extension of the traditional distinction between long run and short run asymmetries to new categories of asymmetries such as contemporaneous impact distributed lag effect cumulated impact reaction time equilibrium and momentum equilibrium adjustment path regime effect regime equilibrium adjustment path each empirical study is then critically discussed in the light of this new classification of asymmetries third this paper evaluates the relative merits of the most popular econometric models for price asymmetries namely autoregressive distributed lags partial adjustments error correction models regime switching and vector autoregressive models finally we use the meta regression analysis to investigate whether the results of asymmetry tests are not model invariant and find which additional factors systematically influence the rejection of the null hypothesis of symmetric price adjustment the main results of our survey can be summarized as follows i each econometric model is specialized to capture a subset of asymmetries ii each asymmetry is better investigated by a subset of econometric models iii the general significance of the f test for asymmetric price transmission depends mainly on characteristics of the data dynamic specification of the econometric model and market characteristics overall our empirical findings confirm that asymmetry in all its forms is very likely to occur in a wide range of markets and econometric models

lags in the response of gasoline prices to changes in crude oil prices the role of short term and long term shocks abstract using weekly data for the period march 1991 to august 2002 we estimate the response of retail gasoline prices to changes in crude oil and spot gasoline prices in the us allowing for a possibility of two types of cost shocks to the gasoline market long term and short term shocks our conclusion is that theoretical models should be developed that allow more than one type of input price changes and the different effect of input price changes on output prices the empirical results support the conjecture of two types of cost shocks as such we find that lags in the response of retail gasoline prices to changes in crude oil prices may be due to the fact that approximately 97 of changes in crude oil prices are viewed as short term by the market participants when two types of shocks are considered there is large difference between the cumulative response function of gasoline prices to long term and short term shocks to crude oil prices as such this paper adds to our understanding of the price stickiness of gasoline prices

the taxation effect on gasoline price asymmetry nexus evidence from both sides of the atlantic this paper explores the degree of competition in various gasoline markets and infers possible causes of price asymmetry across the globe for this purpose we use the dynamic ordinary least square method in order to estimate price asymmetry in twelve european countries and the united states for a sample of weekly observations which spans the period from june 1996 to august 2011 the results indicate the common perception that less competitive gasoline markets exhibit price asymmetry while highly competitive gasoline markets follow a symmetric price adjustment path finally the inclusion of taxes vat and excise tax into retail gasoline prices supports the existence of price asymmetry in many european countries

do gasoline prices respond asymmetrically in the euro zone area evidence from cointegrated panel data analysis this paper uses the generalized method of moments gmm estimation to a panel data error correction model ecm in order to measure the asymmetries in the transmission of shocks to input prices and exchange rate onto the wholesale and retail gasoline price respectively for this purpose we use an updated data set of 6369 weekly observations january 2000 to february 2011 for 11 euro zone countries the results indicate the existence of asymmetric responses in the retail and wholesale segment due to possible reasons oligopolistic structure of the refining industry existence of consumers search costs regulatory and legal barriers

comparing shocks and frictions in us and euro area business cycles a bayesian dsge approach this paper estimates a dsge model with many types of shocks and frictions for both the us and the euro area economy over a common sample period 1974 2002 the structural estimation methodology allows us to investigate whether differences in business cycle behaviour are due to differences in the type of shocks that affect the two economies differences in the propagation mechanism of those shocks or differences in the way the central bank responds to those economic developments our main conclusion is that each of these characteristics is remarkably similar across both currency areas copyright 2005 john wiley sons ltd

is there a fiscal free lunch in a liquidity trap this paper uses a dsge model to examine the eects of an expansion in government spending in a liquidity trap the spending multiplier can be much larger than in the normal situation if the liquidity trap is very persistent and scal stimulus can be rapidly implemented moreover the budgetary costs may be minimal as the large response of output boosts tax revenues allowing for something close to a scal free lunch however we caution that the multiplier may be much smaller under plausible implementation lags for many types of public spending and or if the liquidity trap lasts less than two years in addition because the marginal impact of scal expansion decreases in the scale of the outlay it is crucial to distinguish between average and marginal multipliers

do petrol prices increase faster than they fall in market disequilibria abstract this paper tests the idea that petrol prices respond more quickly to price increases than to decreases we show that the results previously documented in the literature for australia are spurious due to failure to establish the stationarity property of the price series and the co integration relationship between retail and wholesale prices when neglecting to account for a regime shift in the data using a robust approach involving a threshold error correction model we find little evidence to support the contention that retail petrol price reverts asymmetrically to long run equilibrium asymmetric adjustments in retail prices are found only in four of the twenty eight retail gas stations in queensland these results cast doubt on the previously reported pervasiveness of this asymmetric price response phenomenon in australia we further caution on erroneous inference with the use of weekly rather than daily data and when failing to account for a regime shift in the data

modeling investment sector efficiency shocks when does disaggregation matter the most straightforward way to analyze investment sector productivity developments is to construct a two sector model with a sector specific productivity shock an often used modeling shortcut accounts for such developments using a one sector model with shocks to the efficiency of investment in a capital accumulation equation this shortcut is theoretically justified when some stringent conditions are satisfied using a two sector model we consider the implications of relaxing several of the conditions that are at odds with the u s input output tables including equal factor shares across sectors the effects of productivity shocks to an investment producing sector of our two sector model differ from those of efficiency shocks to investment in a one sector model notably expansionary productivity shocks boost consumption in every period whereas expansionary efficiency shocks cause consumption to fall substantially for many periods

rockets and feathers revisited an international comparison on european gasoline markets this paper re examines the issue of asymmetries in the transmission of shocks to crude oil prices onto the retail price of gasoline relative to the previous literature the distinguishing features of the present paper are i use of updated and comparable data to carry out an international comparison of gasoline markets ii two stage modeling of the transmission of oil price shocks to gasoline prices first refinery stage and second distribution stage in order to assess possible asymmetries at either one or both stages iii use of asymmetric error correction models to distinguish between asymmetries that arise from short run deviations in input prices and from the speed at which the gasoline price reverts to its long run level iv explicit possibly asymmetric role of the exchange rate as crude oil is paid for in dollars whereas gasoline sells for different sums of national currencies v bootstrapping of f tests of asymmetries in order to overcome the lowpower problem of conventional testing procedures in contrast to several previous findings the results generally point to widespread differences in both adjustment speeds and short run responses when input prices rise or fall

can exchange rate pass through explain the asymmetric gasoline puzzle evidence from a pooled panel threshold analysis of the eu abstract this study contributes to the literature since it tries to link the exchange rate pass through erpt with the rockets and feathers hypothesis using a panel of eu 28 countries allowing for the existence of an endogenous threshold variable our empirical findings indicate that the threshold model is better suited to this analysis than the baseline linear adjustment model this is the case since the latter restricts the threshold to be centered around zero and the dynamic response to cumulative shocks cannot be properly identified the empirical findings reveal that the threshold variable expressed by the trade weighted dollar exchange rate index is statistically significant only in the sample above the threshold high regime this means that for the net eu exporting countries fluctuations in the real effective exchange rate of the us against its major eu trading partners do affect the level of pre tax retail gasoline prices with the relevant elasticity exceeding unity complete erpt moreover all the statistical tests reject the null hypothesis that there is no significant threshold and thus an asymmetric adjustment gasoline mechanism prevails the impulse response functions confirm our empirical findings that erpt can explain asymmetric gasoline pricing within the eu periphery

disinflation shocks in the eurozone a dsge perspective we investigate the effects of disinflation policies on key macroeconomic variables using euro area data and structural vector autoregressions svars we identify disinflation shocks as the only shocks that drive nominal variables to a lower long run level we find that in the immediate aftermath of a disinflation shock the euro area enters in a persistent recession we use these dynamic responses to estimate a dsge model with imperfect information about the disinflation shock we find that both nominal and real frictions and monetary policy gradualism have played a prominent role in the recessionary effect of disinflation shocks conversely allowing for imperfect credibility does not yield a better fit except when we shut key model s frictions down

price asymmetry in the dutch retail gasoline market abstract this article analyses the retail price adjustments in the dutch gasoline market we estimate an asymmetric error correction model on weekly price changes for the years 1996 2001 we construct five datasets one for each working day the conclusions on asymmetric pricing are shown to differ over these datasets suggesting that the choice of the day for which the prices are observed matters more than commonly believed in our view the insufficient robustness of the outcomes might explain the mixed conclusions found in the literature using these two approaches we also show that the effect of asymmetry on the dutch consumer costs is negligible
