do r d tax credits work evidence from a panel of countries 1979 1997 this paper examines the impact of fiscal incentives on the level of r d investment an econometric model of r d investment is estimated using a new panel of data on tax changes and r d spending in nine oecd countries over a 19 year period 1979 1997 we find evidence that tax incentives are effective in increasing r d intensity this is true even after allowing for permanent country specific characteristics world macro shocks and other policy influences we estimate that a 10 fall in the cost of r d stimulates just over a 1 rise in the level of r d in the short run and just under a 10 rise in r d in the long run

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

taxation of outbound direct investment economic principles and tax policy considerations this paper reviews economic principles for optimality of the taxation of international profit from both a global and national perspective it argues that for traditional systems based on the residence of the investor or the source of the income nothing less than full harmonisation across countries can achieve global optimality the conditions for national optimality are more difficult to identify but are most likely to imply source based taxation however source based taxation requires an allocation of the profits of multinational companies to individual jurisdictions this is not only very difficult in practice but in some cases is without any conceptual foundation the taxation of interest income on a residence basis is also hard to justify if the aim of the tax system is to tax only the income arising from economic activity in a given country

optimal auction with resale this paper investigates the design of seller optimal auctions when winning bidders can attempt to resell the good in that case the optimal allocation characterized by myerson 1981 cannot be achieved without resale i find a sufficient and necessary condition for sincere bidding given the possibility of resale in two bidder cases i prove that the myerson allocation can be achieved under standard conditions supplemented with two assumptions with three or more bidders achieving the myerson allocation is more difficult i prove that it can be implemented in special cases in those cases the myerson allocation is generated through a sequence of resale auctions each optimally chosen by a reseller

chinese liquidity effects on the australian macroeconomy 2002 2017 abstractchina s growing importance to the australian economy has been well recognized in policy circles but remained relatively untested in formal empirical analysis this paper examines the reacti

investigating m3 money demand in the euro area abstract euro area monetary growth has exceeded its target since 2001 likewise recent empirical studies did not find evidence in favour of a stable long run money demand function in contrast to the bulk of the literature we are able to identify a stable long run money demand relationship this result is obtained when the analysis is done without the short run homogeneity restriction between money and prices the basic equation can be improved by allowing for asymmetric adjustment in a low inflation environment opportunity costs of holding money have decreased thus the apparent monetary overhang is reconciled within standard models

monetary policy and oil price shocks empirical implications of alternative responses large swings in the price of oil which have occurred during tha past two decades have substantially affected us inflation unemployment and economic growth in the light of those experiences a debate has arisen over how monetay policy should respond this study contributes to that debate by evaluating empirically the economy s performance under three realistic monetary policy response rules by doing so it advances what has largely been a theoretical discussion the policy rules studied money growth targets nominal gdp growth targets and interest rate targets are evaluated by estimating how closely the resulting economic outcomes approximate an optimal outcome the optimal outcome arises when the fed follows a well defined optimal response rule of the three strategies a nominal gdp target is found to be mose desirable while an interest rate target is least desirable

renewable energy consumption and industrial production a disaggregated time frequency analysis for the u s abstract this paper aims to analyze the interaction between renewable energy consumption and industrial production for the u s over the 1981 2018 period we contribute to the existing literature by the disaggregation of renewable energy sources hydropower geothermal and biomass by the consideration of time and frequency through wavelet techniques and the time varying granger causality test recently proposed by shi et al 2018 based on monthly data wavelet results show a positive co movement between industrial production and biomass energy consumption at low frequencies meaning in the long term only the bootstrap rolling window granger causality test indicates a bi directional predictability between renewable energy consumption and industrial production in crisis and turmoil periods only these results are found to be robust to the inclusion of control variables non renewable energy consumption and crude oil prices and to the selection of the lag length for the corresponding var model

econometric developments in agricultural and resource economics the first 100 years this article reviews the major contributions of agricultural and resource economists in the area of econometrics over the past 100 years early on a number of agricultural economists were in on the ground floor in terms of developing new econometric methods over time as the economics profession became more empirically oriented agricultural and resource economists increasingly assumed the role of early adopters of new econometric methods even so agricultural and resource economists continue to make useful modifications to econometric techniques in order to adapt the methods to the unique nature of the problems and applications that we study

variance of agricultural prices industrial prices and money the relative uncertainty of agricultural prices and industrial prices with respect to the uncertainty of growth in the money supply are investigated utilizing multivariate arch and garch analysis the conditional variances of agricultural prices were shown to dwarf the variances of industrial prices and the money supply the relatively greater sensitivity of the conditional variance of agricultural prices to changes in the variance of the money supply than industrial prices found in this analysis provides a further perspective on the uncertainty confronting farmers including the impacts of the monetary policy shock that precipitated the farm financial crisis in the early 1980s

first price auctions with resale abstract we present a simple model of first price auction with two bidders whose valuations are not identically distributed and where resale is possible between the bidders and given an explicit expression for the equilibrium strategies

a small monetary system for the euro area based on german data previous euro area money demand studies have used aggregated national time series data from the countries participating in the european monetary union emu however aggregation may be problematic because macroeconomic convergence processes have taken place in the countries of interest therefore in this study quarterly german data until 1998 are combined with data from the euro area from 1999 until 2002 and these series are used for fitting a small vector error correction model for the monetary sector of the emu a stable long run money demand relation is found for the full sample period moreover impulse responses do not change much when the sample period is extended by the emu period provided the break in the extended data series is captured by a simple dummy variable copyright 2006 john wiley sons ltd

the optimal taxation of international investment income a comment in a recent issue of this journal thomas horst 1980 presented an elegantly simple set of formulas for optimal taxes on foreign source capital earnings unlike most previous treatments horst s incorporates interest elastic supplies of capital it also includes domestic taxes on capital the presence of these taxes assumes special importance when capital supplies vary with the rate of return to discover the optimal level of tax to impose on foreign source capital earnings one needs to know the opportunity cost of removing a unit of capital from the domestic economy horst s answer following harberger 1976 and others is to use a weighted sum of gross and net rates of return the assumption is that when a unit of capital is exported part is taken from domestic production and part comes from new savings the opportunity cost of the first part is the gross of tax rate of return and of the second the net of tax return to capital thus we get a weighted sum this formulation because it explicitly considers the role of savings or desired asset stocks in setting the tax rate is a big step forward however horst s conclusions apply only under very limited conditions first it is necessary to recognize that capital is not a good but rather constitutes expenditures on future goods tax policies toward capital affect welfare by altering relative prices of present and future goods thereby altering the distribution of consumption over the life cycle see feldstein 1978 tax effects on capital supplies come about through this alteration in life cycle consumption patterns therefore the best way to assess welfare effects of altering the capital supply is with a utility function that can be used to compare different consumption patterns i e an intertemporal utility function section i below demonstrates that such a function can be used to obtain a general measure of the opportunity cost of exported capital

monetary impacts on prices in the short and long run some evidence from new zealand this paper presents support for long run monetary neutrality based on evidence that individual time series for money manufacturing prices and agricultural prices are nonstationary but cointegrated with a stationary proportional long run relationship among their levels dynamic simulations from a vector error correction model with this restriction imposed show that monetary shocks shift relative prices in favor of agriculture in the short run and permanently raise nominal prices manufacturing price shocks have similar long run effects but initially place agriculture in a cost price squeeze while agricultural price shocks are transitory and have little impact on the other series

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

on passive money there are two ways in which the quantity of money may be included in a general equilibrium system as a datum whose value is fixed exogenously or as an unknown whose value is determined by the equilibrium system itself let them be called active money and passive money respectively current monetary theory uses the first approach the ricardo walraskeynes tradition in general equilibrium models is clearly of the activemoney variety this is also true of the more contemporary versions such as patinkin s well known system 1965 apart from the main stream of thought however a number of analyses exist which imply passive money the gold standard model as it is usually expounded belongs to this class the price of gold in terms of money is given while the stock of money is endogenously determined by the set of equilibrium conditions the form in which the quantity of money adapts to its equilibrium level differs according to the institutional mechanism convergence is assured through monetization and demonetization of gold in the pure goldcurrency system and through convertibility of notes into gold and vice versa in the gold standard system with paper money in either case the money supply is allowed to conform to its equilibrium volume this kind of monetary system in which the money price of a certain product or commodity is a datum and the quantity of money a dependent magnitude may be denoted in general as a commodity standard

interpreting euro area inflation at high and low frequencies abstract several authors have recently interpreted the european central bank s ecb s two pillar framework as separate approaches to forecast and analyse inflation at different time horizons or frequency bands the ecb has publicly supported this understanding of the framework this paper presents further evidence on the behaviour of euro area inflation using band spectrum regressions which allow for a natural definition of the short and long run in terms of specific frequency bands and causality tests in the frequency domain the main finding is that variations in inflation are well explained by low frequency movements of money and real output growth and high frequency fluctuations of the output gap

impact of the financial crisis on indian commodity markets structural breaks and volatility dynamics the shocks transmitted across the financial markets during the financial crisis resulted in structural changes in commodity volatility hence understanding volatility dynamics in changing scenario is vital for derivative pricing risk management and monetary policy stabilization this paper studies the impact of the financial crisis by analyzing the following aspects 1 presence of structural break regime shift in volatility by deploying markov and wavelet model during financial crisis and 2 crisis impact on volatility dynamic behavior such as persistence leverage and long memory by deploying hybrid wavelet egarch and fractional integration spot prices of 18 commodities were examined including all sub sectors of energy metals and agriculture indian commodity indices sub indices global benchmark indices and also stock indices such as sp agricultural commodities showed faster convergence to long run equilibrium while metal and energy experienced higher persistence and attracted more financial speculation the impact of the crisis on agricultural commodities was limited to internationally traded commodities such as sugar and rubber the common breaks and different volatility dynamics have been attributed to systematic risk and to idiosyncratic components respectively it was also found that during and after the crisis more than idiosyncratic risk it was systematic risk that contributed significantly to the volatility patterns of indian commodity markets

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

commodity price changes and the predictability of economic policy uncertainty in this study we forecast economic policy uncertainty epu using input on 23 commodity price changes we reveal the significant predictability of epu using three forecast combinations this indicates that commodity price changes can be taken as a leading indicator of epu

on the taxation of multinational corporate investment when the deferral method is used by the capital exporting country abstract the user cost of capital for a subsidiary is derived when the capital exporter uses the deferral method for the taxation of the parent s foreign source income the hartman sinn result implying that the capital exporter s tax on remitted dividends is irrelevant to a subsidiary using retentions to finance investment is shown to be correct only when host and home countries have similar corporate income tax bases otherwise both the home and host country corporate tax provisions influence the cost of capital it is also shown that a cash flow tax by the capital importer is not neutral owing to interactions with the capital exporter s tax regime

forecasting vector autoregressions with bayesian priors the paper explores the justification for and application of bayesian priors in forecasting a vector autoregression a nonsymmetric random walk prior outperforms three alternative time series representations in forecasting five series of the u s hog market

dynamics of oil price precious metal prices and exchange rate this study examines the co movements and information transmission among the spot prices of four precious metals gold silver platinum and palladium oil price and the us dollar euro exchange rate we find evidence of a weak long run equilibrium relationship but strong feedbacks in the short run the spot precious metal markets respond significantly but temporarily to a shock in any of the prices of the other metal prices and the exchange rate furthermore we discover some evidence of market overreactions in the palladium and platinum cases as well as in the exchange rate market in conclusion whether there are overreactions and re adjustments or not investors may diversify at least a portion of the risk away by investing in precious metals oil and the euro policy implications are provided

identifying monetary impacts on agricultural prices in var models since the mid 1970s a number of studies have used vector autoregressive var models to evaluate the magnitude and timing of macroeconomic impacts on agriculture use of the var method has been viewed as a way to obtain empirical evidence about these impacts that might not emerge from more traditional overidentified and less dynamic econometric models the hope has been that by placing minimal restrictions on var models the true structure of the economic relationships under investigation can be observed while the aim is laudable critics of var models have argued that it has had the unfortunate consequence of obscuring some important structural identification issues and seeming to promise that something can be obtained for nothing cooley and leroy leamer they point out that identifying restrictions are required to give economically interpretable meaning to the results of any simultaneous equation model sem in standard practice identification of var models is obtained implicitly by choice of a choleski decomposition of the covariance matrix of one step ahead forecast errors which is equivalent to imposing a recursive structure for the economy of concern is that the recursive structure may not be believable further as bernanke has observed examination of ad hoc variants of the recursive order implies a strange set of prior beliefs in which the analyst holds strongly that the system is recursive but is not sure in what order the variables should be arranged in response to these concerns several recent papers have pointed out that identification of var models does not have to rely on the assumption that the contemporaneous structure is recursive bernanke sims rather the distinguishing features of a var model are first that identification rests on the assumption that distinct mutually orthogonal behavior shocks drive the economy and second that lagged relationships among the endogenous and exogenous variables if any are left entirely unrestricted given these features a var model must be identified solely by restrictions placed on the contemporaneous interactions among the variables but the identifying restrictions do not have to preclude simultaneity in this paper we elaborate on the structural interpretation of var models and use this analysis to examine monetary impacts on agricultural prices we discuss the identification problem and the implications of a recursive structure we illustrate our points with respect to the three variable model of money industrial prices and agricultural prices that has been used in several articles to evaluate the effects of monetary shocks on price dynamics bessler devadoss and meyers we then introduce a somewhat richer behavioral model of the macroeconomy and its effects a simultaneous model is shown to offer a more believable identification of monetary policy and other macroeconomic shocks than a recursive model and monetary impacts on agricultural prices are assessed

global oil prices macroeconomic fundamentals and china s commodity sector comovements abstract this paper investigates the common movements of commodity sectors in china as well as the economic underpinnings of the comovements we employ a bayesian dynamic latent factor model to disentangle the common and idiosyncratic sector specific factors of the prices of a group of china s commodity sectors petrochemicals grains energy non ferrous metals oils fats and softs the results indicate that the common factor accounts for a significant portion of the fluctuations of china s commodity sectors providing evidence of the strong commodity sector comovements in china we further use a var model to link the common movements across china s commodity sectors to the underlying determinants including global oil price shocks and domestic macroeconomic fluctuations we find that the global oil price shocks have strong effects on the common movements across commodity sectors in china in addition to its domestic macroeconomic fluctuations at long horizons however at short horizons the common movements across commodity sectors in china respond more strongly to the global oil shocks than to its domestic macroeconomic fluctuations

effects of fiscal policies on us agriculture according to the macro rational expectation mre hypothesis only unanticipated macroeconomic policy has impacts on real economic variables and anticipated policy changes have no real impacts this study analysis the effects of the anticipated and unanticipated components of fiscal policy on the us farm real gnp by testing the neutrality and rationality propositions of the mre hypothesis the test results show that both the rationality and neutrality propositions are rejected the empirical findings indicate that the anticipated fiscal policy does have significant effects on farm output examination of a specific sector sheds light on the nature of the market and helps ascertain the resons for the non neutrality

credit constraints interest rates and agricultural prices although there are some earlier contributions the paper by schuh the exchange rate and u s agriculture touched off a controversy within the agricultural economics profession that has yet to be resolved in its original form the controversy centered around whether or not exchange rates had a significant effect on u s agricultural prices exports and farm income later the argument seems to have moved one step further back along the logical line to a question of whether or not monetary phenomena can have real effects thus to some extent agricultural economists interested in this issue have polarized themselves into two camps that closely resemble what for lack of a better term might be called keynesians and non keynesians this paper is not an attempt to settle this dispute indeed if observations based on developments in macroeconomics offer any guide i think that the dispute is based upon such fundamentally different perceptions of the world that no single paper or series of papers will ever settle the issue rather in this paper i want to discuss what i perceive to be one of the key issues in this debate are agricultural prices more flexible than nonagricultural prices my choice of this topic is somewhat personal and i choose it mainly because i feel that if monetary variables are going to have real effects these effects can only be short run in nature and are best explained by differential price adjustments the argument is simple suppose you have two goods a and b and suppose that good a is priced administratively a la gardiner means while good b s price is perfectly flexible now suppose further that the money supply is artificially inflated in the current instances the price of a will not adjust instantaneously while the price of b is free to adjust if the price of b does adjust as a result of an increase in the money s pply then manipulation of the money supply has caused a real change since the price ratio between a and b changes in this case therefore we can also expect other real changes in the economy but such effects should be only short run in nature the real effects set in motion by the relative price change should ultimately be self correcting under the usual ceteris paribus assumptions since even administered prices have to adjust in the long run to maintain entrepreneurial profitability however even if such issues of relative flexibility are not a central element in the discussion that is germane to the present paper and the associated controversy the general belief that agricultural prices are more flexible than nonagricultural prices is firmly rooted in the stylized facts of agricultural economics moreover the high degree of instability of agricultural prices is often given as the primary argument for extensive government interference in the agricultural economy in what follows i will first offer a brief survey of some of the studies of the effects of monetary phenomena on u s agricultural prices exports and incomes in this part of the paper i specifically exclude papers of what i think of as the is inflation neutral with

factor endowments and welfare levels in an asymmetric tax competition game abstract this paper addresses capital tax competition among an arbitrary number of countries countries are asymmetric not only in their population endowment but also in their capital endowment per inhabitant national governments tax capital and labor in order to finance a fixed public budget asymmetric capital taxation arises at equilibrium leading to a distortion on the international capital market we fully characterize how equilibrium taxes and welfare levels depend upon countries population and capital endowments we compare it to the autarky situation and show that fiscal competition erodes some but not all of the gains from capital markets liberalization

effects of global liquidity on commodity and food prices summary this article investigates the relationship between global liquidity and commodity and food prices applying a global cointegrated vector autoregressive model we use different measures of global liquidity and various indices of commodity and food prices for the period 1980 2011 our results support the hypothesis that there is a positive long run relation between global liquidity and the development of food and commodity prices and that food and commodity prices adjust significantly to this cointegrating relation global liquidity in contrast does not adjust it drives the relationship

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

inflation and the distribution of price changes across markets a causal analysis recent advances in time series methodology are applied to the investigation of causal relationships between monthly changes in the consumer price index and changes in its dispersion across different consumption categories this dispersion is associated with the degree to which relative prices are changing past inflation rates seem useful in forecasting changes in relative prices but not vice versa there is also a significant contemporaneous correlation between these series hence it is concluded that fluctuations in the inflation rate help cause fluctuations in relative prices but not vice versa unless the entire effect occurs within a month the analysis also serves to illustrate a new way to implement the granger causality concept

constructing historical euro zone data existing methods of reconstructing historical euro zone data by aggregation of the individual countries aggregate data raises numerous difficulties especially due to past exchange rate changes the approach proposed here is designed to avoid such distortions and aggregate exactly when exchange rates are fixed we first compute growth rates within states aggregate these then cumulate this euro zone growth rate to obtain the aggregated levels variables the aggregate of the implicit deflator plice index coincides with the implicit deflator of our aggregate nominal and real data we apply the method to euro zone m3 gdp and prices over the previous two decades 1 background with the introduction on 31 december 1998 of the irrevocably fixed euro exchange rates eleven countries of the european union entered a new monetary union from that date onwards monetary policy for these countries is set by the newly formed european central bank ecb the governing council of the ecb bases its monetary policy on medium term assumptions regarding real gdp growth and the trend decline in the velocity of circulation of m3 ecb 1999a p 40 therefore the construction of historical data for aggregate m3 and gdp for the euro zone is of practical relevance to policy makers in addition any econometric model for euro zone countries requires such historical data this paper describes an approach to doing so from the aggregate data of the individual member states a number of previous reconstructions are noted but as these have important drawbacks an approach related to that in t6rnqvist 1936 is proposed and its properties are discussed although there have been many important contributions to index number theory see section 4 few are directly relevant to the problem confronted here where we wish to use the national aggregates from member states not the individual item data usually input into index calculations to construct a euro zone aggregate moreover the inherently non stationary nature of those national aggregates both from unit roots inducing integrated time series

causality of u s agricultural prices and the money supply further empirical evidence empirical evidence presented in this study indicates that the results of causality tests of u s agricultural prices and the money supply are sensitive to the lag selection relying on the minimum final prediction error causality testing technique a unidirectional causal flow is established from the monetary base to retail level agricultural prices no such flow is found to exist from m2 to retail agricultural prices when farm level agricultural prices are investigated no causal flow exists from any of the measures of the money supply to farm prices

financial liquidity geopolitics and oil prices abstract this paper aims simultaneously to study the global dynamic relationship of oil prices financial liquidity and geopolitical risk on the one hand and the economic performance of oil exports dependent economies on the other global and country specific dynamics are studied together in a global vector autoregression gvar model that allows different lag structures for different variables in different countries global impulse response functions from the estimated model suggest that new waves of high oil prices are unlikely despite the likely continuation of high global financial liquidity and heightened geopolitical risk which had driven earlier episodes of very high oil prices with oil remaining at modest to low prices by recent historical standards we study the prospects for economic growth in oil export dependent economies through dramatic increases in domestic investment as planned under visions 2030 of some arab countries and conclude that unfortunately success is unlikely

implications of the macroeconomic outlook for agriculture this paper analyzes the implications for agriculture of the macroeconomic scenarios put forth by bosworth and lawrence a substantial body of work in recent years has developed both the theoretical framework and empirical evidence on the channels of influence between the macroeconomy and agriculture the aaea sponsored preconference workshop this year entitled value of large scale aggregate models for economic policy analysis manifests the profession s interest in quantifying the effects that macroeconomic factors have upon the economic performance and financial health of agriculture this paper draws upon the findings of previous work in general terms but more specifically we present the agricultural implications of two alternative macroeconomic environments implied by an existing macroeconomic model which emphasizes agriculture s interface with the macroeconomy the second section of this paper reviews the major findings of the literature on transmission mechanisms linking agriculture with the general economy the third section provides key details of how agriculture fares under bosworth and lawrence s outlook for the general economy through 1990 including the implications for farm prices cash receipts wealth and financial stress the fourth section discusses the consequences of one potential deviation from bosworth and lawrence s out

the dynamic responses of crop and livestock prices to money supply shocks a bayesian analysis using long run identifying restrictions the impact of monetary policy on agriculture has been much debated this study examines the dynamic responses of u s agricultural prices to money supply shocks using three innovations first the variables responses are identified by long run money neutrality restrictions instead of the more common contemporaneous ordering second a bayesian approach to model uncertainty is used to add robustness to the estimation process third agricultural prices are disaggregated into crop and livestock components the empirical results find that both agricultural sectors benefit in the short run from positive money supply shocks with agricultural prices increasing relative to the general price level

does the euro follow the german mark evidence from the monetary model of the exchange rate abstract this paper investigates whether german or synthetic european pre emu data provides the appropriate empirical basis for evaluating euro dollar exchange rate behavior monetary exchange rate equations are estimated for both data sets over the pre emu period and out of sample forecasts are evaluated to assess their ability to explain the euro dollar exchange rate from 1999 to 2004 while forecast accuracy tests confirm the usefulness of synthetic european data for euro exchange rate analysis forecasts based on the german pre emu experience cannot even beat a random walk our results indicate that the euro does not simply follow the german mark but that it has its origins in the other pre emu currencies as well

on the exposure of the bric countries to global economic shocks the financial crisis led to a deep recession in many industrial countries while large emerging countries recovered relatively quickly from the financial crisis their performance deteriorated in the last years despite the modest recovery in advanced economies the higher divergence of business cycles is closely linked to the chinese transformation during the crisis the chinese fiscal stimulus prevented a decline in gdp growth not only in that country but also in resource rich economies the chinese shift to consumption driven growth led to a decline in commodity demand and the environment became more challenging for many emerging markets this view is supported by bayesian vars specified for the bric brazil russia india and china countries the results reveal a strong impact of international variables on gdp growth in contrast to the other countries china plays a crucial role in determining global trade and oil prices hence the change in the chinese growth strategy puts additional reform pressure on countries with abundant natural resources

do countries compete over corporate tax rates this paper tests whether oecd countries compete with each other over corporate taxes in order to attract investment we develop two models with firm mobility countries compete only over the statutory tax rate or the effective average tax rate while with capital mobility countries compete only over the effective marginal tax rate we estimate the parameters of reaction functions using data from 21 countries between 1983 99 we find evidence that countries compete over all three measures but particularly over the statutory tax rate and the effective average tax rate this is consistent with a belief amongst governments that location choices by multinational firms are discrete we also find evidence of concave reaction functions consistent with the model outlined in the paper

the effects of macroeconomic factors on south african agriculture significant research efforts have been devoted to understanding the effects of macroeconomic factors on the agriculture sector analysing the sources of volatility in the industry is critical for designing appropriate policies to stabilize agricultural markets reduce poverty and increase economic growth agriculture is a competitive sector with prices that are more flexible than those in nonagricultural sectors this article uses annual data over the 1957 2004 period and a vector error correction model in investigating the dynamic effects of exchange rates money supply and other macroeconomic variables on the agricultural sector in south africa overall real exchange rates interest rates inflation and money supply m3 shocks have significant and persistent impacts on agricultural output prices received by farmers and farm input prices m3 and interest rate shocks tend to put agriculture in a cost price squeeze agricultural price movements are a source of macroeconomic instability in the country r

relative agricultural prices and monetary policy an imperfect information rational expectations model of relative price determination is presented this model provides an econometric specification for testing for a causal relationship between money and the relative prices of agricultural commodities test results indicate that variations in the growth rate of the nominal money supply whether anticipated or unanticipated have not been an important influence on the average level of prices received by farmers relative to other prices in the economy over the period 1951 85

interrelationships between monetary instruments and agricultural commodity trade during the last decade agricultural economists have devoted increasing attention to the macroeconomic aspects of agricultural problems indeed a recent presidential address to the american agricultural economics association tweeten centered on the macroeconomics of agriculture given the currency of the monetary approach to macroeconomics it is not surprising therefore that there is also a growing interest in the effects of monetary instruments and monetary phenomena on agricultural commodity trade in this paper i shall discuss what i feel are some of the most pertinent issues that researchers must address in this area before we proceed too far with our discussion it is important to define what i mean by a monetary instrument perhaps arbitrarily i reserve the term monetary instrument for those macroeconomic variables which are primarily determined within domestic or international monetary markets obvious examples are the level of the money supply interest rates and exchange rates i justify the term instrument by noting that as far as the agricultural sector is concerned these variables are by and large predetermined for example the levels of the money supply and interest rates in the united states are to a large extent determined by the policy of the federal reserve similarly the price of the currency the exchange rateis ultimately determined by the demand and the supply for the currency and thus at least partially by governmental policy the first step in any attempt to outline research needs and goals is an identification of what has been done in the past although the literature on the macroeconomics of agriculture is farily large and rapidly expanding eckstein and heien lamm schuh 1976 and tweeten are important examples relatively li tl attention has been given to the effect of monetary instruments on agricultural trade what attention has been given to this area of resea ch has revolved mainly around the role of exchange rates in determining agricultural exports and prices thus it is logical to start our discussion with a brief survey of the literature on exchange rates and agriculture

asymmetric auctions with resale we study first and second price auctions with resale in a model with indepen dent private values with asymmetric bidders the resulting inefficiencies create a motive for post auction trade which in our model takes place via monopoly pricing the winner makes a take it or leave it offer to the loser we show a a first price auction with resale has a unique monotonic equilibrium and b with resale the expected revenue from a first price auction exceeds that from a second price auction the inclusion of resale possibilities thus permits a gen eral revenue ranking of the two auctions that is not available when these are excluded jel d44

the informational role of commodity prices in formulating monetary policy a reexamination abstract this paper reexamines the issue of whether commodity prices provide useful information for formulating monetary policy through the application of a recent development in time series methodology developed by toda and yamamoto j econometrics 66 1995 225 250 we found that commodity prices signal the future direction of the economy

legal institutions and fragile financial markets abstract this study investigates equity liquidity variation with a funding constraint across 38 countries and examines whether the effectiveness of a country s legal institutions is systematically related to cross country differences in fragile equity liquidity our results show that firms from countries with more extensive disclosure requirements tend to have lower liquidity shocks due to funding constraints leading to higher firm value this effect is stronger for ex ante disclosures especially for countries with a high level of openness and market volatility our empirical results are robust to the 2sls regression model the random effect regression model the alternative measure of fragile equity liquidity and the alternative measure of disclosure and enforcement variables our study provides a better understanding of the effect of information environments amidst periods of funding constraint

commodity dynamics a sparse multi class approach abstract the correct understanding of commodity price dynamics can bring relevant improvements in terms of policy formulation both for developing and developed countries agricultural metal and energy commodity prices might depend on each other although we expect few important effects among the total number of possible ones some price effects among different commodities might still be substantial moreover the increasing integration of the world economy suggests that these effects should be comparable for different markets this paper introduces a sparse estimator of the multi class vector autoregressive model to detect common price effects between a large number of commodities for different markets or investment portfolios in a first application we consider agricultural metal and energy commodities for three different markets we show a large prevalence of effects involving metal commodities in the chinese and indian markets and the existence of asymmetric price effects in a second application we analyze commodity prices for five different investment portfolios and highlight the existence of important effects from energy to agricultural commodities the relevance of biofuels is hereby confirmed overall we find stronger similarities in commodity price effects among portfolios than among markets

the influence of biofuels economic and financial factors on daily returns of commodity futures prices abstract biofuels production has experienced rapid growth worldwide as one of the several strategies to promote green energy economies indeed climate change mitigation and energy security have been frequent rationales behind biofuel policies but biofuels production could generate negative impacts such as additional demand for feedstocks and therefore for land on which to grow them with a consequent increase in food commodity prices in this context this paper examines the effect of biofuels and other economic and financial factors on daily returns of a group of commodity futures prices using generalized autoregressive conditional heteroskedasticity garch family models in univariate and multivariate settings the results show that a complex of drivers are relevant in explaining commodity futures returns more precisely the standard and poor s s p 500 positively affects commodity markets while the us euro exchange rate brings about a decline in commodity returns it turns out in addition that energy market returns are significant in explaining commodity returns on a daily basis while monetary liquidity is not this would imply that biofuel policy should be carefully monitored in order to avoid excessive first generation subsidization which would trigger a fuel vs food conflict

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

auctions with resale reserve prices and revenues abstract we study auctions with resale and reserve prices we characterize the equilibrium and compare the revenues of the first price auction with that of the second price auction we show that several results change when a reserve price is introduced first the second price auction may yield higher revenues than the first price auction second the strong bidder is more likely to win than the weak bidder

relative prices and money a vector autoregression on brazilian data recent data on brazilian agricultural prices industrial prices and money supply are analyzed in a vector autoregression the empirical findings show strong one way granger type causality from money supply to agricultural prices while feedback is observed between industrial prices and money supply under the usual monetarist ordering of contemporaneous innovation covariance agricultural prices do not adjust faster than industrial prices to a shock in the money supply

effects of international shocks and domestic macroeconomic policies upon brazilian agriculture abstract an identified vector autoregressive model is used to analyze the transmission of external commodity shocks to the brazilian economy the effects of the interaction between domestic macroeconomic monetary and exchange rate policies and external shocks to agricultural commodity raw material and food prices and crude oil price upon domestic agriculture industry terms of trade are estimated

the demand for m3 in the euro area in this paper an empirically stable money demand model for m3 in the euro area is constructed starting with a multivariate system three cointegrating relationships with economic content are found i the spread between the long term and the short term nominal interest rates ii the long term real interest rate and iii a long run demand for broad money m3 there is evidence that the determinants of m3 money demand are weakly exogenous with respect to the long run parameters hence following a general to specific modelling approach a parsimonious conditional error correction model for m3 money demand is derived which can be interpreted economically for the conditional model long run and short run parameter stability is extensively tested and not rejected copyright 2001 john wiley sons ltd

alternative indicators for predicting the probability of declining inflation evidence from the us the performance of inflation indicators for predicting the probability of inflation falling inside constant and moving targets is considered with a probit model using us data given the federal reserve system s emphasis on achieving price stability particular attention is given to the target that future inflation will be below recent inflation in contrast with earlier years the unemployment and capacity utilisation rates do not perform well in forecasting the direction of inflation in the mid and late 1990s we suggest that extending the keynesian phillips curve analysis to consider changes in labour market conditions technological advance and worker skills and openness will increase understanding of these issues

commodity price dynamics and anticipated shocks in this paper we address the robustness of overshooting hypothesis in agricultural prices we find that agricultural prices may undershoot their long run level if the economy experiences an anticipated monetary shock rather than an unanticipated monetary shock we also find that agricultural prices definitely display undershooting if the price of manufactures adjusts instantaneously rather than sluggishly

macroeconomic impacts on bulgarian agriculture during transition an unstable and erratic macroeconomy in an economy in transition might be expected to affect agricultural performance this is tested for bulgaria between 1992 and 1997 using impulse response functions from a vector autoregressive var model despite data limitations it is found that shocks to the foreign exchange rate and interest rate feed into farm prices and agricultural exports but equilibrium will be re established within 5 years agricultural policies may not be sufficient to counteract the wider macroeconomic forces

neutrality of inflation in the agricultural sector abstract the paper considers the effect of inflation on the relative prices of products traded in auction markets prices of us agricultural products are used for the period 1951 1981 since agricultural products are widely traded the real forces of supply and demand specific to agriculture are represented by foreign agricultural prices the exchange rate is entered as a separate variable influencing domestic agricultural prices trade between the usa and the ten countries included in the federal reserve board s trade weighted dollar is considered the empirical results are consistent with the hypothesis that inflation did not alter relative agricultural prices when the real forces of supply and demand and the exchange rate are held constant

optimality and the english and second price auctions with resale abstract in the presence of resale and under more general assumptions than zheng s 2002 implementation of myerson s 1981 optimal allocation with two bidders is achieved through the second price auction in a special class of asymmetric n bidder models it is achieved through the english auction

relative prices and money further results for the united states empirical results support the hypothesis that agricultural prices respond faster than manufactured product prices to a change in money supply in the united states sims vector autoregression var technique was applied in examining this hypothesis the monte carlo integration method was used to test the significance of the impulse responses generated by the var technique

international tax competition and gains from tax harmonization abstract in a world economy there are two types of distortions which can be caused by capital income taxation in addition to the standard closed economy wedge between the consumer saver marginal intertemporal rate of substitution and the producer investor marginal productivity of capital i international differences in intertemporal marginal rates of substitution implying an inefficient allocation of world savings across countries and ii international differences in the marginal productivity of capital implying an inefficient allocation of world investment across countries the paper focuses on the structure of taxation for countries which are engaged in tax competition and on potential gains from a tax harmonization we show that if the competing countries are sufficiently coordinated with the rest of the world then tax competition leads each country to apply the residence principle of taxation and there are no gains from tax harmonization if however there is not sufficient coordination then tax competition leads to low capital income taxes and the tax burden falls on the internationally immobile factors the outcome is nevertheless still efficient relative to the available constrained set of tax instruments

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

european tax harmonisation and production efficiency this paper analyses the impact on production efficiency of potential harmonisation of the taxation of income from capital in the european union it develops and applies a methodology for computing the cost of capital for transnational investments to assess the degree to which production efficiency holds in the eu it considers the impact of potential forms of corporation tax harmonisation the results indicate that some commonly advocated reforms e g harmonising tax rates or tax bases would not significantly move the tax system towards production efficiency but that other reforms which affect the taxation of cross border flows would have more impact

monetary policy rules and the indicator properties of asset prices abstract we investigate relationships between asset prices and inflation in a modern keynesian model in which monetary policy controls inflation by manipulating the federal funds rate the indicator properties of asset prices are quite sensitive to the monetary policy rule including the asset prices themselves in the reaction function can invert the sense of the indicator properties targeting the asset prices is tantamount to targeting the real interest rate when all of the weight in the reaction function is placed on asset prices the real rate converges so rapidly that policy loses control of inflation

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

what drives natural gas prices in the united states a directed acyclic graph approach abstract this study investigates the impacts of driving factors for natural gas prices during the period from 1999 to 2017 a data driven approach namely the directed acyclic graph dag is first employed to disclose the contemporaneous relations among natural gas crude oil and various factors the main results indicate that there is a stable contemporaneous causal flow from crude oil to natural gas unlike most of the previous research we found a long term equilibrium relationship between crude oil and natural gas returns when additional factors were taken into account however the impact of oil price returns on natural gas price volatility has decreased after the 2008 global financial crisis finally storage and seasonality factors can never be ignored when analysing natural gas prices while the impact of speculative activity on natural gas volatility is relatively weak

does global liquidity drive commodity prices abstract this paper tackles the question of whether a cross sectional perspective on monetary policy is capable of explaining movements in global commodity prices in this vein we contribute to the rich literature on global liquidity in two different ways on the one hand to achieve a global series in terms of common monetary policy shocks we propose a distinction between common and idiosyncratic factors across economies as proposed by bai and ng 2004 our second innovation stems from the consideration of a markov switching vector error correction model when analyzing time varying short run dynamics having identified the long run structure which includes a proportional relationship between commodity prices and global liquidity in the first step our results indeed show that the impact of a global liquidity measure on different commodity prices is significant and varies over time one regime approximately accounts for times where commodity prices significantly adjust to disequilibria while the second regime is characterized by either a weak or no commodity price adjustment the fact that global liquidity also reacts to disequilibria in a specific regime demonstrates the two way causality between monetary policy and commodity prices

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

the development trinity how regional integration impacts growth inequality and poverty developing countries today have become more active participants in regional trade agreements this raises questions about how the benefits of integration are distributed and the extent to which lower income countries are able to capture development gains historically such impacts have been difficult to identify with precision this paper seeks to address this gap by empirically analysing the impact of regional integration on development particularly the effects on growth and welfare using both bilateral and regional integration measures we show that the ability to capture gains from integration varies across developing country regional groups with developing asia benefiting on par with developed countries the findings in the paper indicate that trade and trade policy play an important role in reducing inequality and poverty in developing countries it also shows that regionalism can function as a channel to make multilateralism a more adept way of addressing national challenges
