money and capital abstract the effects of money anticipated inflation on capital formation is a classic issue in macroeconomics previous papers adopt reduced form approaches putting money in the utility function or imposing cash in advance but using otherwise frictionless models we follow instead a literature that tries to be explicit about the frictions making money essential this introduces new elements including a two sector structure with centralized and decentralized markets stochastic trading opportunities and bargaining these elements matter quantitatively and numerical results differ from findings in the reduced form literature the analysis also reduces a gap between microfounded monetary economics and mainstream macro

limited commitment and the demand for money understanding money demand is important for our comprehension of macroeconomics and monetary policy its instability has made this a challenge common explications for the instability are financial regulations and financial innovations that shift the money demand function we provide a complementary view by showing that a model where borrowers have limited commitment can significantly improve the fit between the theoretical money demand function and the data limited commitment can also explain why the ratio of credit to m1 is currently so low despite that nominal interest rates are at their lowest recorded levels this article is protected by copyright all rights reserved

demand for money in open economies abstract the demand for real cash balances deduced from an underlying portfolio model of the financial market is shown to depend upon domestic variables and foreign monetary developments the model is estimated using quarterly postwar data for canada germany uk and us there is clear evidence that demand for money is affected not only by changes in domestic variables such as permanent income domestic interest rate and price expectations but also by fluctuations in exchange rate expectations and foreign interest rates the conclusion that domestic monetary policy is fairly ineffective and domestic financial markets are highly vulnerable to changes in foreign financial and monetary developments need to be modified in light of the results presented in this paper

comparison shopping as a simultaneous move game this paper analyzes simultaneous move models of comparison shopping it shows that the equilibria in wilde schwartz 1979 can be rationalized as symmetric mixed strategies in an appropriately defined game in which information acquisition costs are endogenous it also shown that in the simultaneous move version of salop stiglitz 1977 nonexistence of equilibrium is not a problem in fact a variety of forms of equilibria emerge in that model pure strategy mixed strategy and blends of the two copyright 1992 by royal economic society

re examining the buffer stock model of money this paper critically examines recent papers in the buffer stock or supply side disequilibrium models of money the paper first investigates the assumptions at the m icroeconomic level and concludes that even with these assumptions aggregate behavior does not necessarily follow buffer stock models in which excess cash balances are held involuntarily in a simple model with uncertain cash flows it is shown that in the aggregate short run involuntary cash holdings are negligible if the buffer stock story is applicable it is to a broader definition of money than used in most empirical work the second part of the paper examines empirical work and argues that the buffer stock idea cannot be implemented using single equation techniques and that when viewed appropriately current empirical result s refute the buffer stock idea as it is currently modeled copyright 1987 by royal economic society

the impact of wind power generation on the electricity price in germany abstract this paper investigates the relationship between intermittent wind power generation and electricity price behaviour in germany using a garch model i evaluate the effect of wind electricity generation on the level and the volatility of the electricity price in an integrated approach the results show that variable wind power reduces the price level but increases its volatility this paper s results also indicate that regulatory change has stabilised the wholesale price the electricity price volatility has decreased in germany after a modification of the marketing mechanism of renewable electricity this gives confidence that further adjustments to regulation and policy may foster a better integration of renewables into the power system

slovak electricity market and the price merit order effect of photovoltaics abstract this paper analyses slovak electricity market with a focus on photovoltaic energy it evaluates the impact of the solar electricity penetration into electricity mix on spot prices seeks evidence of the merit order effect in the slovak electricity market and quantifies it based on hourly data the multivariate regression analysis covers the period 2011 2016 the rather small merit order effect estimated by an ols time series model leads to the small decrease of slovak electricity wholesale prices this spot price reduction attributable to the photovoltaics does not outweigh the costs of the support scheme borne by end users what implies a consumer loss

changes to gate closure and its impact on wholesale electricity prices the case of the uk abstract the electricity supply industry in the united kingdom underwent a number of regulatory reforms since late 80 s that have transformed the trading and pricing of the energy market herein we provide empirical evidence that the modification proposal p12 mod p12 that took place in 7 2 2002 moving the gate closure gc interval from 3 5 h to 1 h before real time has caused a permanent alteration in the uk spot price volatility using a combination of recurrence plot rp and recurrence quantification analysis rqa we find that after the the change in the gc time short term price volatility significantly decreased between 2001 and 2008 while long term price volatility is not affected by cg change similar results are obtained by means of spectral analysis on the price series showing a significant reduction in its variability the results of our analysis suggest that a dynamical regime shift of the price occurred and such shift is linked to the gc change whereby shorter gc intervals facilitate short term forecasting on electricity demand and better reliability on the supply side therefore gc closer to real time is associated to reduced price fluctuations in the wholesale market

inflation and welfare in a monetary economy it is in everyone s private interest to try to get someone else to hold non interest bearing cash and reserves but someone has to hold it all so these efforts must simply cancel out all of us spend several hours per year in this effort and employ thousands of talented and highly trained people to help us these person hours are simply thrown away wasted on a task that should not have to be performed at all

estimating money demand functions the question of which functional forms of money demand regression equations are useful for empirical work is addressed here specifically it is argued that a functional form that focuses attention on the ability of the growth rate of nominal money to predict the inflation rate is a useful way of summarizing empirical evidence on the existence of a stable money demand function the results of estimating and simulating this functional form as well as standard functional forms are presented in the final part of this paper a typical equation expressing the public s demand for real money balances m is as follows

the identification of monetary policy disturbances explaining the liquidity puzzle abstract this paper examines recent work on the identification of monetary policy disturbances its main finding is that the empirical anomalies found in the literature reflect a failure to properly address the federal reserve s policy of accommodating reserve demand shocks a new method of identifying monetary policy using nonborrowed reserves is proposed using this specification policy has a strong persistent liquidity effect regardless of subsample policy granger causes output even in the presence of interest rates explaining approximately 49 of the variance in output at a two year horizon and the residual explanatory power of interest rates for output is negligible

the impact of renewable energy forecast errors on imbalance volumes and electricity spot prices abstract this paper contributes to the general consideration of whether a policy of incentivising system operators to improve the quality and market availability of forecasts for renewable energy outputs would be beneficial using data from the german electricity market we investigate the effect of wind and solar energy forecasts errors on imbalance volumes and subsequent spot electricity prices we use ordinary least squares regression quantile regression and autoregressive moving averages to identify these relationships using variables that have a quarter hourly data granularity the results show that higher wind and solar forecast errors increase the absolute values of imbalance volumes and that these can pass through into higher spot prices we find that wind forecast errors in germany impact spot prices more than solar forecasting errors policy incentives to improve the accuracy and availability of renewable energy forecasts by the system operators should therefore be encouraged

us business credit sources demand deposits and the missing money abstract this study accounts for much of the missing money in the us through compensating balances business lending by banks affects demand deposit growth standard money demand models include variables that likely pick up income and interest rate effects on the transactions demand for demand deposits and on compensating balance requirements provided that bank lending to firms is stable however during the missing money period business shifted toward nonbank sources of short term credit causing a decline in compensating balances empirical finding support this hypothesis as a partial explanation for the missing money using the federal reserve board s demand deposit model

money credit and banking in monetary models where agents are subject to trading shocks there is typically an ex post inefficiency since some agents are holding idle balances while others are cash constrained this problem creates a role for financial intermediaries such as banks who accept nominal deposits and make nominal loans in general financial intermediation improves the allocation the gains in welfare come from the payment of interest on deposits and not from relaxing borrowers liquidity constraints we also demonstrate that when credit rationing occurs increasing the rate of inflation can be welfare improving

endogenous search price dispersion and welfare abstract this paper studies the welfare cost of inflation in a frictional monetary economy with endogenous consumer search equilibrium entails price dispersion where sellers compete for buyers by posting prices we identify three channels through which inflation affects welfare the real balance channel is the source of welfare loss its interaction with the price posting channel generates a welfare cost larger than lucas 2000 the search channel reduces the welfare cost by more than one half through general equilibrium effect the aggregate effect of these three channels on welfare is non monotonic additionally the welfare cost of inflation fluctuations is negligible

imperfect information monopolistic competition and public policy introduction ever since the pioneering work of george stigler 1961 and the provocative survey by michael rothschild 1973 economists have recognized that general equilibrium models yield competitive equilibria only by making strong assumptions about the information available to market participants in response to this difficulty theorists in recent years have developed a family of search equilibrium models that presuppose homogeneity and the absence of price discrimination and which also assume that information acquisition costs are positive for at least a subset of buyers on the basis of these and other assumptions the models attempt to show how price dispersion equilibria can arise solely as a result of the strategies that firms and consumers pursue one author summarized the results if information is costly each small firm obtains market power so that the relevant market structure with imperfect information is not per ect competition but rather monopolistic competition steven salop 1976 p 240

is quantity theory still alive this paper investigates whether the quantity theory of money is still alive we argue that it is but that the slippage is not negligible for countries with low inflation the relationship between average inflation and the growth rate of money is tenuous at best a correction for variation in output growth and the opportunity cost of money using theory implied elasticities helps explain the slippage for the period since 1990 inflation targeting at low rates of inflation makes it harder to establish the long run relationship between monetary growth and inflation

a search theoretic approach to monetary economics the essential function of money is its role as a medium of exchange the authors formalize this idea using a search theoretic equilibrium model of the exchange process that captures the double coincidence of wants problem with pure barter one advantage of the framework described here is that it is very tractable the authors also show that the model can be used to addre ss some substantive issues in monetary economics including the potenti al welfare enhancing role of money the interaction between specializat ion and monetary exchange and the possibility of equilibria with multip le fiat currencies copyright 1993 by american economic association

monopolistic competition when price and quality are imperfectly observable consider the symmetric equilibrium of a monopolistically competitive industry in which manufacturers select price and quality to maximize expected profit and consumers maximize utility by conducting costly search among sellers using an optimal sequential search rule consumers search among sellers because i each consumer idiosyncratically evaluates each seller s quality and ii a retailing sector generates variation in the prices consumers pay consumers are handicapped in their search because their observations of firms price and quality levels are noisy an improvement in price information is represented by an increase in the precision with which consumers observe sellers prices similarly an improvement in quality information is represented by an increase in precision with which consumers observe sellers quality levels an improvement of either type of information may increase or decrease welfare the perverse case in which improved price information decreases welfare occurs when price competition among firms becomes so intense relative to quality competition that firms select severely suboptimal levels of quality a consumer searching among monopolistically competitive sellers may have difficulty accurately observing the price and quality of each seller s product he must infer from his prior beliefs and noisy observations the true values of the product s price and quality attributes we show that increasing the precision with which consumers observe an attribute of a product makes the inference problem easier and causes the demand the seller faces with respect to that attribute to become more elastic the equilibrium level of that attribute changes accordingly and since the equilibrium levels of price and quality interact the equilibrium level of the other attribute changes as well these equilibrium effects can be perverse in two ways first if the precision of quality observation is fixed then improvement in the precision of price observation can reduce welfare the chain of causation is this increasing the precision of price observation causes price to fall the resulting smaller price cost margin induces sellers to reduce quality de

balancing energy strategies in electricity portfolio management traditional management of electricity portfolios is focused on the day ahead market and futures of longer maturity within limits market participants can however also resort to the balancing energy market to close their positions in this paper we determine strategic positions in the balancing energy market and identify corresponding economic incentives in an analysis of the german balancing energy demand we find that those strategies allow an economically optimal starting point for real time balancing and create a marketplace for flexible capacity that is more open than alternative marketplaces the strategies we proffer in this paper we believe will contribute to an effective functioning of the electricity market

cross country estimates of the demand for money and its components the demand for money aggregates m1 m2 and their components currency demand deposits and time deposits are estimated using a sample of 103 countries at two time periods money demand is found to be affected by age literacy industrial development and political structure as well as income and inflation this expanded demand function helps to explain the considerable changes in money demand that have occurred over long periods and the large variation in money demand found across countries the knowledge thus gained is useful for understanding differences in monetary and taxation policies across countries

on the coexistence of money and higher return assets and its social role this paper adopts mechanism design to investigate the coexistence of at money and higherreturn assets we consider an economy with pairwise meetings where at money and riskfree capital compete as means of payment as in lagos and rocheteau 2008 the trading mechanism in pairwise meetings is chosen among all individually rational renegotiation proof mechanisms to maximize society s welfare we show that in any stationary monetary equilibrium capital commands a higher rate of return than at money

sticky prices a new monetarist approach why do some sellers set nominal prices that apparently do not respond to changes in the aggregate price level in many models prices are sticky by assumption here it is a result we use search theory with two consequences prices are set in dollars since money is the medium of exchange and equilibrium implies a nondegenerate price distribution when the money supply increases some sellers may keep prices constant earning less per unit but making it up on volume so profit stays constant the calibrated model matches price change data well but in contrast to typical sticky price models money is neutral jel e52 e31 e42

modeling the demand for narrow money in the united kingdom and the united states abstract despite the importance of well specified empirical money demand functions for inference forecasting and policy problems in modeling have arisen concerning the economic theories of money demand the data institutional frameworks financial innovation and econometric implementation by developing constant data coherent m 1 demand equations for the u k and the u s we investigate these issues and explain such puzzles as missing money the great velocity decline and the recent explosion in m 1 the endogeneity of money the lucas critique and the non invertibility of our m 1 models are also discussed

price quality and timing of moves in markets with incomplete information an experimental analysis this paper reports the results of theoretical and experimental analyses of search models of shopping behavior earlier work which dealt with markets for homogeneous goods in which sellers first determined their prices and buyers then decided upon their information acquisition shopping strategies conditional upon the distribution of prices showed that nash equilibria for these markets were good predictions of outcomes of laboratory experiments the authors extend the analysis to markets with heterogeneous goods and allow buyers and sellers to move simultaneously the results of a series of laboratory experiments indicate that the nash equilibria continue to be good predictions in these more realistic settings copyright 1992 by royal economic society

state dependent pricing inflation and welfare in search economies abstract we investigate the welfare effects of inflation in economies with search frictions and menu costs we first analyze an economy where there is no transaction demand for money balances money is a mere unit of account we determine a condition under which strictly positive inflation is desirable we relate this condition to a standard efficiency condition for search economies second we consider a related economy in which there is a transaction role for money in the absence of menu costs the friedman rule is optimal in the presence of menu costs the optimal inflation rate is negative for our numerical examples provided menu costs are small a deviation from the friedman rule can be optimal depending on the extent of the search externalities

precautionary balances and the velocity of circulation of money the observed low velocity of circulation of money implies that households hold more money than they normally spend a natural explanation for this behavior is that households face uncertain expenditure needs so they have a precautionary motive for holding money we investigate the precautionary demand for money in a search model where households are subject to preference shocks the model predicts that the velocity of circulation of money is not only low but also interest elastic the model closely fits united states data on the velocity of circulation of money and interest rates that span the period 1892 2003 the empirical analysis reveals a dramatic reduction in precautionary balances towards the end of our sample probably linked to innovations in the information technology this drop in precautionary balances is crucial for important issues of monetary economics such as the elasticity of the demand for money and the welfare cost of inflation

on the market impact of wind energy forecasts this paper presents an analysis of how day ahead electricity spot prices are affected by day ahead wind power forecasts demonstration of this relationship is given as a test case for the western danish price area of the nord pool s elspot market impact on the average price behaviour is investigated as well as that on the distributional properties of the price by using a non parametric regression model to assess the effects of wind power forecasts on the average behaviour the non linearities and time variations in the relationship are captured well and the effects are shown to be quite substantial furthermore by evaluating the distributional properties of the spot prices under different scenarios the impact of the wind power forecasts on the price distribution is proved to be considerable the conditional price distribution is moreover shown to be non gaussian this implies that forecasting models for electricity spot prices for which parameters are estimated by a least squares techniques will not have gaussian residuals hence the widespread assumption of gaussian residuals from electricity spot price models is shown to be inadequate for these model types the revealed effects are likely to be observable and qualitatively similar in other day ahead electricity markets significantly penetrated by wind power

inflation and welfare a search approach this paper extends recent findings in the search theoretic literature on monetary exchange regarding the welfare costs of inflation we present first estimates of the welfare cost of inflation using the welfare triangle methodology of bailey 1958 and lucas 2000 we then derive a money demand function from the search theoretic model of lagos and wright 2005 and we estimate it from u s data over the period 1900 2000 we show that the welfare cost of inflation predicted by the model accords with the welfare triangle measure when pricing mechanisms are such that buyers appropriate the social marginal benefit of their real balances for other mechanisms welfare triangles underestimate the true welfare cost of inflation because of a rent sharing externality we also point out other inefficiencies associated with noncompetitive pricing which matter for estimating the cost of inflation we then illustrate how endogenous participation decisions can mitigate or exacerbate the cost of inflaion and we provide calibrated examples in which a deviation from the friedman rule is optimal finally we discuss distributional effects of inflation

new concepts of aggregated money the federal reserve board s recent redefinition of its monetary aggregates followed three years of intensive board staff research on monetary aggregation while the new aggregates ultimately were selected along conventional lines some of the staff s research was oriented towards more fundamental changes in monetary aggregation methods this paper reviews such proposals which are based upon the rigorous application of index number and aggregation theory and of principal components analysis in the construction of economic monetary aggregates the usefulness of aggregation and index number theory in acquiring price indices is widely known the theory of the true cost of living index is an application of aggregation theory examples of applied index number theory include the commerce department s implicit price deflator which is a paasche index and the labor department s consumer price index which is a laspeyres index somewhat less well known is the fact that dual to the theory of economic price aggregates and indices is a theory of economic quantity aggregates and indices an example of a highly reputable quantity index is the divisia quantity index the monetary aggregates traditionally are thought to measure the supplied quantity of an economic good called money whenever monetary aggregates are used in the context of economic theory rather than as simple accounting identities the theory of economic quantity aggregation is specifically applicable however published monetary aggregates in all countries have always been computed as simple sums but as fisher 1922 p 29 observed in the conclusion to his classic treatise on index number theory the simple arithmetic average produces one of the very worst of index numbers and if this book has no other effect than to lead to the total abandonment of the simple arithmetic type of index number it will have served a useful purpose with an example of the simple sum index fisher 1922 p 363 found that the bias alone reaches 36 percent although index number theory has not yet found its way into the monetary theory literature all of the literature on index number theory and aggregation theory for the past half century supports the result long ago deduced by fisher 1922 p 361 that the simple arithmetic index should not be used the views expressed herein are solely those of the authors and do not necessarily represent the views of the board of governors of the federal reserve system this research was partially supported by national science foundation grant soc 76 84459 we are deeply indebted to the conference session s discussant of this paper w erwin diewert for volunteering to cede his allocated journal space to us so that the paper could take its current extended form federal reserve board washington d c

on the instability of long run money demand and the welfare cost of inflation in the united states we evaluate the policy implications of measuring the welfare cost of inflation accounting for instabilities in the long run money demand for the u s over the period 1900 2013 we extend the analysis and reassess the results reported in lucas 2000 and ireland 2009 also considering the recent theoretical contributions of lucas and nicolini 2015 and berentsen et al 2015 breaks in the long run money demand give rise to regime dependent welfare cost estimates we find that the welfare cost is about 0 1 of annual income over 1976 2013 as compared to 0 8 over 1945 1975 overall these values are substantially lower than those reported in the literature

financial innovations money demand and the welfare cost of inflation in the 1990s the empirical relation between money demand and interest rates began to fall apart we analyze to what extent improved access to money markets can explain this break down for this purpose we construct a microfounded monetary model with a money market which provides insurance against liquidity shocks by offering short term loans and by paying interest on money market deposits we calibrate the model to u s data and find that improved access to money markets can explain the behavior of money demand very well furthermore we show that by allocating money more efficiently better access to money markets decrease the welfare cost of inflation substantially

the search for a stable money demand function a survey of the post 1973 literature phe question of whether the demnand function for money is stable is one of the most important recurring issues in the theory and application of macroeconomic policy what is being sought in a stable demand function is a set of necessary conditions for money to exert a predictable influence on the economy so that the central bank s control of the money supply can be a useful instrument of economic policy as such the notion of a stable demand function appears to involve three key elements e g john t boorman 1976 p 317 and david e w laidler 1977 pp 34 35 first the demand for money relation should be highly predictable in a statistical sense as measured by the usual goodness of fit statistics precision of estimated coefficients and presumably its ability to forecast accurately out of sample second a stable demand function for money has relatively few arguments a relationship that requires knowledge about a large number of variables in order to pin it down is in effect not predictable finally the variables that appear as arguments in the function should represent significant links to spending and economic activity in the real sector in sum a stable demand function for money means that the quantity of money is predictably related to a small set of key variables linking money to the real sector of the economy the importance of a stable money demand function for monetary policy can be illustrated with the standard is lm model in which interest rates and gnp are the endogenous variables in this context a stable demand function for money translates into a well defined relationship between money interest rates and gnp

money and capital as competing media of exchange we construct a model where capital competes with fiat money as a medium of exchange and we establish conditions on fundamentals under which fiat money can be both valued and socially beneficial when the socially efficient stock of capital is too low to provide the liquidity agents need they overaccumulate productive assets to use as media of exchange when this is the case there exists a monetary equilibrium that dominates the nonmonetary one in terms of welfare under the friedman rule fiat money provides just enough liquidity so that agents choose to accumulate the same capital stock a social planner would

money financed fiscal stimulus the effects of implementation lag abstract previous studies argue that based on the new keynesian framework a fiscal stimulus financed by money creation has a strong positive effect on output under a reasonable degree of nominal price rigidities this paper investigates the effects of an implementation lag in a money financed fiscal stimulus on output we show that if a money financed government purchase has a time lag between the decision and the implementation 1 it may cause a recession rather than a boom when the economy is in normal times 2 it may deepen a recession when the economy is in a liquidity trap 3 the longer the implementation lag the deeper the recession and 4 the depth of the recession depends on the interest semi elasticity of money demand our results imply that if money demand is unstable the money financed fiscal stimulus with an implementation lag may have unstable effects on output in contrast to the debt financed fiscal stimulus

the redistributive effects of inflation and the shape of money demand abstract i quantify the distributional effects of expected inflation in a sample of oecd countries using a microfounded model of money where agents differ in their consumption risk against which they can insure using money and government bonds the model is calibrated using harmonized wealth microdata from the luxembourg wealth study i find that the inflation tax is progressive for low inflation levels but it becomes regressive as inflation increases cut off points vary across countries and depend on discount factors and heterogeneity in consumption risk across agents moreover i find that the magnitude of inflation s distributional impact depends not only on wealth distribution but also and importantly on the curvature and height of the money demand curve indeed a higher and less elastic money demand leads to more regressive effects of inflation thus implying such effects are not necessarily stronger in a country with a more unequal wealth distribution

cointegration and structural change an application to the u s demand for money wankeun oh i perform the cointegration tests for the trivariate model of real monetary aggregates real personal income and short term interest rate i find the existence of a long run relationship among these three variables to check the stability of a long run money demand relationship i implement a rank constancy test and cusum test the test results show that real mi is relatively more stable than other aggregates but structural change occurred during the 1970s and early 1980s this is consistent with prior research on money demand jel e41 i introduction incorporating structural change when performing tests on the properties of stochastic processes is important because structural breaks may cause misspecification problems most tests of structural change consider the stability of the parameters over time tests for structural breaks and parameter stability have been studied extensively a partial list includes chow 1966 brown et al 1975 harvey and collier 1977 king 1987 ploberger et al 1989 in the context of unit root processes perron 1989 showed that the presence of a one time change in the level or slope of the trend function can severely distort the results of unit root tests and it is natural to ask how structural change can distort the results of cointegration tests 1 traditional tests of parameter stability ask if the parameters of the model are constant in contrast quintos 1993 proposed a test for stability of the long run relationship s in a cointegrating regression the test is based on johansen s 1988 framework and the test statistic is simply the weighted sum of the likelihood ratio test as given in johansen 1988 quintos s rank test is very different from the traditional cusum and chow tests for parameter stability because her rank test checks for stability of the cointegrating relationship between variables in other words the rank test checks whether cointegration holds for the full period the traditional cusum and chow tests assume that cointegration holds for the full period or does not hold for the full period and tests simply whether the cointegration vector changes for example if there is cointegration from 1960 1990 between revenues and expenditures with cointegrating vector 1 1 then the cusum and chow tests check whether the cointegra ting vector 1 1 is stable throughout the period the rank constancy test checks whether the cointegration rank is stable throughout the period not whether the cointegrating vector is stable at 1 1 in other words the rank test will check whether for example there is cointegration from 1960 1980 and no cointegration from 1980 onward the chow and cusum tests are not designed to check for this the structural stability of money demand relationships has been the issue of a substantial number of empirical studies 2 in general structural stability means stability of the underlying behavioral equations 3 this term includes parameter stability and stability of functional form friedman s 1990 research on the money demand function assumes that a long run equilibrium relationship exists between real money balances real income or real wealth and the opportunity cost of holding real money balances recently there has been strong evidence of cointegration between real income real money balances and a nominal interest rate for instance engle and granger 1987 dickey et al 1991 hafer and jansen 1991 hoffman and rasche 1991 mehra 1993 miller 1991 fischer and nicoletti 1993 and baba et al 1992 report on cointegration among variables in u s aggregate money demand jain and moon 1994 report on cointegration in u s sectoral money demand yashiv 1994 and engsted 1993 on money demand in a high inflation country and hoffman et al 1995 report on international money demand comparison this article asks if long run money demand relationship is stable and if so for which measure of money is it stable over time

contract durations in the electricity market causal impact of 15 min trading on the epex spot market abstract the european power exchange epex introduced two new products in 2011 and 2014 which reduce the delivery duration of electricity from 1 h to 15 min intervals these changes to the market design aim to better reflect the intermittent power generation from renewable energy sources however little is known about trading in shorter intervals and its impact on the existing market as a remedy our evaluation first shows that the market has quickly adopted the new 15 min contracts second we estimate a bayesian structural time series which measures a causal decrease of electricity prices depending on the model specification our results indicate that the reduction can be as high as 28 for existing hourly contracts subsequent to the introduction of 15 min trading third the use of 15 min contracts coincides with intermittent power generation as it incentivizes renewable energy providers to offer additional electricity altogether our findings suggest that 15 min trading is used to balance the intra hour volatility of renewable energy sources consequently this presents a blueprint for policy makers who can attain similar price reductions and larger feed ins from renewable energy sources without direct costs in all countries with high shares of renewable energy sources

uncertainty and shopping behaviour an experimental analysis this paper reports experimental tests of three search equilibrium models these models which differ only in the search strategies available to the buyers have qualitatively different predictions that is equilibria price distributions single price equilibria at the competitive price and at the monopoly price and two price equilibria the experimental outcomes generally were consistent with the models predictions this suggests that debate on the utility of this class of models should shift to the realism of the models assumptions rather than focus on their ability to characterize market outcomes also since the basic models have been validated the project of analyzing experimentally the results of relaxing some of their assumptions seems worthwhile

short term electricity trading for system balancing an empirical analysis of the role of intraday trading in balancing germany s electricity system abstract previous studies have noted that unexpectedly germany s dramatic expansion of wind and solar energy coincided with a reduction of short term balancing reserves this observation has been dubbed the german balancing paradox this paper provides further and updated evidence since 2011 wind and solar energy have nearly doubled while both reserve requirements and reserve use have declined by 50 the paper quantitatively explores one reason for reduced balancing needs increased and improved short term wholesale electricity trading on the intraday market trading is now commonly done around the clock and based on quarter hour rather than full hour contracts the shift to quarter hourly products alone explains a decrease in balancing energy by 17 there is also strong evidence that market parties respond efficiently to imbalance charges suggesting that incentive based approaches to electricity balancing work

degreasing the wheels of finance can there be too much trading in financial markets we construct a dynamic general equilibrium model where agents face idiosyncratic liquidity shocks a financial market allows agents to adjust their portfolio of liquid and illiquid assets in response to these shocks the optimal policy is to restrict access to this market because portfolio choices exhibit a pecuniary externality agents do not take into account that by holding more of the liquid asset they not only acquire additional insurance against these liquidity shocks but also marginally increase the value of the liquid asset which improves insurance for other market participants

on the welfare cost of inflation and the recent behavior of money demand post 1980 u s data trace out a stable long run money demand relationship of cagan s semi log form between the m1 income ratio and the nominal interest rate with an interest semi elasticity of 1 79 integrating under this money demand curve yields estimates of the welfare cost of modest departures from friedman s zero nominal interest rate rule for the optimum quantity of money that are quite small the results suggest that the federal reserve s current policy which generates low but still positive rates of inflation provides an adequate approximation in welfare terms to the alternative of moving all the way to the friedman rule jel e31 e41 e52

recent instability of the demand for money an international perspective aggregate money demand functions once an apparent bulwark for macroeconomic research have had to be re examined in the light of the events and discoveries of the 1970s following goldfeld s extensive analysis it now is widely recognized that the demand for mi balances in the united states cannot be explained satisfactorily by standard functions apparently because of shifts occurring in the early 1970s similar reservations see below have been expressed with respect to m3 balances in the united kingdom where the demand relationships appear to have been upset by the introduction of regulatory reforms in 1971 in both cases part of the problem can be traced to specific events but the possibility remains that a more general instability may be present the rapid inflation experienced by all major industrial countries after 1973 the concurrent collapse of the bretton woods system of fixed exchange rates and the attempts by most major central banks to control growth in domestic money stocks may all have altered the responses of the demand for money to the standard functional arguments this paper presents a range of stability tests for a set of demand functions estimated for two monetary aggregates in each of six countries in order to determine whether money demand functions more generally have been stable over the recent period and to attempt to identify the nature and causes of any observed instabilities the major conclusions are that none of the other functions examined displays instabilities as severe as those of the mi function for the united states and that the latter may be unstable in a more persistent and fundamental way than has heretofore been recognized the equations estimated for this study are based on a variant of goldfeld s log linear real balances function the deflated value of money balances is related to real income interest rates and inflation with lagged adjustments introduced via a simple koyck transformation this function obviously is in a simplified form especially with respect to the lag struc

short run money demand abstract the conventional wisdom holds that the short run demand for money is unstable this paper challenges the conventional view by finding a stable demand for m1 in u s data from 1959 through 1993 the approach follows previous work in interpreting long run money demand as a cointegrating relation and it uses goldfeld s partial adjustment model to interpret short run dynamics the key innovation is the choice of the interest rate in the money demand function most previous work uses a short term market rate but this paper uses the average return on near monies the savings accounts and money market mutual funds that are close substitutes for m1 this choice helps rationalize the behavior of money demand in particular the increase in the volatility of velocity after 1980 is explained by increased volatility in the returns on near monies

regression direction and weak exogeneity abstract the absence of testing for weak exogeneity in money demand has often led to stark conditioning claims regarding the validity of price equations this paper uses the johansen procedure to explore the conditioning properties of money demand systems for nonborrowed reserves m1 and m2 our results show that irrespective of the specification of the cointegrating relation a feedback mechanism enters the equation for money the opposite however is not true for the price equations the results also cast a warning for single equation models of money demand in that weak exogeneity is sensitive to how the system is defined

the role of money supply shocks in the short run demand for money abstract previous money demand models are either inconsistent with contemporaneous adjustment of the price level to expected changes in the nominal money supply or imply implausible interest rate fluctuations in response to innovations in nominal money we propose a shock absorber money demand model in which money supply shocks affect the synchronization of asset transactions and so engender a temporary increase or decrease in desired money holdings expected changes do not engender such fluctuations in real money inventories in simultaneous estimates for eight industrial countries the shock absorber model proved empirically superior

on cash in advance models of money demand and asset pricing this paper shows how a cash in advance model of money can be written in a way that combines a simple yet empirically defensible money demand function with an asset pricing equation that is similar to the standard barter economy euler equations return premia are determined as in the barter exchange model except that a short term risk free nominal interest rate enters into the first order conditions in special cases asset prices satisfy the barter economy euler equations exactly in the empirical analysis the interest rate factor adds some explanatory power but both the barter and the monetary asset pricing model perform rather poorly copyright 1991 by ohio state university press

unstable money demand and the monetary model of the exchange rate in this paper the authors investigate the importance for the monetary model of exchange rate determination of j frankel 1979 of allowing unrestricted dynamics and of accounting for shifts in the demand for money due to financial innovation based on estimation and simulation results for the canada u s bilateral exchange rate over the 1970 85 period the aut hors find strong evidence in favor of a generalized approach to dynamic specification but find that the shif t adjustment of official money supply data has only minor implications for the empirical results moreover neither modification is sufficient to generate a monetary model that is well supported by the data

price volatility in commodity markets with restricted participation abstract in commodity markets price volatility may rise significantly if the product granularity increases to gain insights into the underlying drivers we analyze price volatility based on the example of german electricity markets we develop a theoretical model to reproduce the price formation in the day ahead and intraday auction which are sequential short term electricity markets with 60 minute and 15 minute products as cross border trade is allowed in the day ahead but not in the intraday auction the model accounts for the impact of restricted market participation the theoretical model is then transferred into an empirical analysis to first validate the modeling approach and second to comparatively assess the impact of increasing product granularity and restricted market participation the empirical results indicate that the disproportional rise in quarter hourly price volatility is mainly triggered by limited market participation and not only by the high volatility of renewable supply and demand since restricted market participation refers to a lack of market coupling we derive a proxy for efficiency losses ranging from eur 55 million to eur 108 million that may be reduced if markets are coupled

fair trades by trade fairs information providing institutions under monopolistic competition it is a standard result of search theory that the optimal reservation supply price e g wage is negatively correlated to search costs this paper applies the inverse relationship between demand prices and limit prices to the analysis of an hitherto unexplored topic trade fairs trade fairs bloomed during the middle ages and early trade based capitalism and survived for centuries in last decades their growth became sustained they attract every year hundreds of thousands of exhibitors and tens of millions of visitors

sweep programs the fall of m1 and rebirth of the medium of exchange this paper investigates the effect of sweep programs on m1 using dynamic simulations of money demand over 1994 2000 the postsample period constitutes when sweep programs have been in effect all models generate predictions systematically above reported m1 using data on newly initiated programs test findings indicate that sweeps account for the overprediction within the conventional money demand model with a long term interest rate we construct a medium of exchange measure m1s equal to m1 plus estimated holdings of sweep balances m1s velocity compares favorably with that of broader aggregates evidence indicates cointegration within m1s money demand

bargaining and the value of money abstract search models of monetary exchange have typically relied on nash 1950 the bargaining problem econometrica 18 155 162 bargaining or strategic games that yield an equivalent outcome to determine the terms of trade by considering alternative axiomatic bargaining solutions in a search model with divisible money we show that the properties of the bargaining solutions do matter both qualitatively and quantitatively for questions of first degree importance in monetary economics such as i the efficiency of monetary equilibrium ii the optimality of the friedman rule and iii the welfare cost of inflation

the impact of renewable energies on eex day ahead electricity prices in this paper we analyze the impact of renewable energies wind and photovoltaic on the formation of day ahead electricity prices at eex we give an overview of the policy decisions concerning the promotion of renewable energy sources in germany and discuss their consequences on day ahead prices an analysis of electricity spot prices reveals that the introduction of renewable energies enhances extreme price changes in the frame of a dynamic fundamental model we show that there has been a continuous electricity price adaption process to market fundamentals furthermore the fundamental drivers of prices differ among hours with different load profiles our results imply that renewable energies decrease market spot prices and have implications on the traditional fuel mix for electricity production however the prices for the final consumers increased overall because they must pay in addition the feed in tariffs for the promotion of renewable energy

a unified framework for monetary theory and policy analysis search theoretic models of monetary exchange are based on explicit descriptions of the frictions that make money essential however tractable versions of these models typically make strong assumptions that render them ill suited for monetary policy analysis we propose a new framework based on explicit micro foundations within which macro policy can be studied the framework is analytically tractable and easily quantifiable we calibrate the model to standard observations and use it to measure the cost of inflation we find that going from 10 percent to 0 percent inflation is worth between 3 and 5 percent of consumption much higher than previous estimates

the value of forecasts quantifying the economic gains of accurate quarter hourly electricity price forecasts abstract we propose a multivariate elastic net regression forecast model for german quarter hourly electricity spot markets while the literature is diverse on day ahead prediction approaches both the intraday continuous and intraday call auction prices have not been studied intensively with a clear focus on predictive power besides electricity price forecasting we check for the impact of early day ahead da exaa prices on intraday forecasts another novelty of this paper is the complementary discussion of economic benefits a precise estimation is worthless if it cannot be utilized we elaborate possible trading decisions based upon our forecasting scheme and analyze their monetary effects we find that even simple electricity trading strategies can lead to substantial economic impact if combined with a decent forecasting technique

inflation and unemployment in the long run we study the long run relation between money measured by inflation or interest rates and unemployment we first document in the data a positive relation between these variables at low frequencies we then develop a framework where unemployment and money are both modeled using microfoundations based on search and bargaining theory providing a unified theory for analyzing labor and goods markets the calibrated model shows that money can account for a sizable fraction of trends in unemployment we argue it matters qualitativelynand quantitatively whether one uses monetary theory based on search and bargaining or an alternative ad hoc specification

econometric analysis of 15 minute intraday electricity prices abstract the trading activity in the german intraday electricity market has increased significantly over the last years this is partially due to an increasing share of renewable energy wind and photovoltaic which requires power generators to balance out the forecasting errors in their production we investigate the bidding behaviour in the intraday market by looking at both last prices and continuous bidding in the context of a reduced form econometric analysis a unique data set of 15 minute intraday prices and intraday updated forecasts of wind and photovoltaic has been employed price bids are explained by prior information on renewables forecasts and demand supply market specific exogenous variables we show that intraday prices adjust asymmetrically to both forecasting errors in renewables and to the volume of trades dependent on the threshold variable demand quote which reflects the expected demand covered by the planned traditional capacity in the day ahead market the location of the threshold can be used by market participants to adjust their bids accordingly given the latest updates in the wind and photovoltaic forecasting errors and the forecasts of the control area balances

the effect of wind and solar power forecasts on day ahead and intraday electricity prices in germany abstract this study analyzes the effects of wind and solar power generation forecasts on electricity prices converse to the existing empirical literature in this area we apply a panel data analysis to control for endogeneity due to unobserved heterogeneity we use a dataset with 24 daily observations of day ahead and intraday prices from 2010 to 2016 and we apply a fixed effects regression under consideration of robust driscoll kraay standard errors a noteworthy element of the regression model is the simulation based design of a variable indicating the power generation technology that is price determining at a certain point in time in this context we differentiate between the fuel types coal gas and others to model the nonlinear price behavior for a varying demand for 2016 we find price dampening effects of both wind and solar power of approximately 0 6 mwh per additional gwh of feed in along with the rapidly increasing shares of wind and solar power of the total power generation during the last years their price dampening effect has declined since 2013 due to a drop in fuel prices another finding is that a reduction in forecasting errors on the power generation from wind and solar and smoothing of the cyclical demand would lead to a decreased price volatility

are price equations really money demand equations on their heads it is often argued that the dependent variable in money demand functions is really the price level the money stock itself being exogenous a recent approach which stresses the theme is the buffer stock hypothesis in which money supply shocks explicitly appear in the demand for money function because prices and interest rates do not adjust rapidly enough to bring about short run equilibrium in the money market although this approach has been adopted by a number of authors it is not been subjected to much econometric testing in this paper we outline the economic and econometric issues involved in testing the exogenous money buffer stock hypothesis and subject it to a variety of tests using three different data sets none of our results supports the hypothesis fundamental restrictions are rejected at very high levels of significance and a reasonably good money demand equation is seen to be badly misspecified if interpreted as a price equation this abstract was borrowed from another version of this item

financial market participation and the apparent instability of money demand abstract this paper uses multi period cross sectional data on financial assets holdings to shed light on the postwar stability of money demand in the united states i first present a new measure of the evolution of financial market participation by relating participation to the extensive margins of money demand and quantify the influence of wealth on participation decisions i then relate the increase in participation to the period of missing money and to the subsequent higher interest rate elasticity of monetary aggregates the paper indicates that time series estimations of money demand relationships are inherently flawed and tend to inappropriately suggest instability

on the stability of money demand abstract we show that regulatory changes that occurred in the banking sector in the early 1980s that considerably weakened regulation q can explain the apparent instability of money demand starting in the same period we evaluate the effects of the regulatory changes using a model that goes beyond aggregates as m1 and treats currency and different deposit types as alternative means of payments we use the model to construct a new monetary aggregate that performs remarkably well for all the period 1915 2012

wind power integration and power system flexibility an empirical analysis of extreme events in germany under the new negative price regime abstract in this article the flexibility of the german power market with respect to the integration of an increasing share of electricity from renewable energy sources was analysed flexibility limiting system components which cause negative prices are explained and illustrated for the german market the decision of the european energy exchange in leipzig to allow negative price bids is then explained the empirical data illustrate the flexibility of conventional generating capacities in germany from october 2008 to december 2009 of the 86 h of negative spot prices 19 h were significantly negative with prices of at least 100 mwh these extreme hours were analysed in greater detail by the examination of different system components thereby load wind power infeed and conventional generation by fuel type were observed as well as the market for negative tertiary reserve as indicators for market tightness although the market situations were found to be severe under the current conditions it could have been much worse in order to enable the market to clear at all times policy recommendations are provided and long run implications of an increasing res e share on the conventional generation capacity are discussed the article concludes with an outlook on additional power system flexibility options

u s narrow money for the twenty first century i introduction though money retains its fundamental role in a market economy money measures have been noticeably de emphasized within the conduct of u s monetary policy the federal open market committee fomc stopped reporting annual growth objectives for monetary aggregates although it states that money supply still has value for gauging economic conditions board of governors 2000 however a growing body of research calls for returning monetary aggregates to a more prominent role within monetary policy meltzer 1998 asserts that the view of persistent money growth as being the source of inflation is again widely accepted perhaps more firmly held by some central bank governors now than at any time in the twentieth century nelson 2002 provides evidence that base money has a significant effect on output relative to potential in the united states and united kingdom even after controlling for the short term real interest rate nelson 2003 argues that money growth governs the mean and dynamics of inflation in present day new keynesian models leeper and roush 2003 find evidence of an essential role for m2 within the transmission of monetary policy even after controlling for the nominal interest rate 1 this article focuses on the role of sweep programs in properly measuring narrow money in a sweep program banks move a portion of funds from customer demand deposits dds or other checkable deposits ocds into instruments with zero statutory reserve requirements we examine the effects of two types of sweep programs in the united states retail sweep programs and commercial demand deposit sweep programs narrow transactions based money historically has played a key role in the conduct of monetary policy as hafer and wheelock 2001 explain m1 served as the measure of money within the st louis model although monetarists had long been divided over whether a narrow or broad aggregate was the preferable target for monetary policy the fomc appeared to focus on m1 during the 1970s and early 1980s publishing their target ranges for money growth in terms of m1 hafer and wheelock 2001 though state that deviations in m1 velocity from its upward trend beginning in the early 1980s caused instability within the st louis model hoffman and rasche 1991 and hoffman et al 1995 place dummy variables in their vector error correction mechanisms to capture observed shifts in m1 velocity what attention remains on the money supply seems to be focused on broad rather than narrow aggregates but the broad aggregates have not escaped difficulties duca 2000 and hafer and wheelock 2001 document a deviation of m2 velocity from its long run trend in the early 1990s sometimes characterized as the missing m2 episode duca and vanhoose 2004 state that one response was to replace m2 with mzm consistent with the view that heightened substitution between small time deposits and mutual funds other than money market mutual funds mmmfs largely accounted for the instability in m2 velocity but as they go on to discuss m2 and mzm velocity encountered problems in the early 2000s plunging in ways not in line with opportunity cost variables duca and van hoose 2004 state that broader aggregates may have become more vulnerable to portfolio substitution involving stock and mutual funds other than mmmf narrow money has also been used extensively in examining money demand a sizable body of research has emerged that empirically investigates the demand for m1 especially using cointegration techniques hoffman and rasche 1991 hoffman et al 1995 dutkowsky and atesoglu 2001 and ball 2001 provide evidence of a stable long run money demand equation using m1 ball 2002 generates further support with m1 and establishes a correspondence between the partial adjustment formulation and the vector error correction model yet research and policy making using narrow money is currently being hampered by the lack of an accurate measure of transactions based money

a comparison among partial adjustment rational expectations and error correction estimates of the canadian demand for money starting from a dynamic optimization principle the currently most popular approaches to modelling money demand functions are derived the partial adjustment adaptive expectations rational expectations and error correction mechanism formulations are then estimated using a common data set the error correction mechanism equation is found to dominate the others either because their implicit restrictions are rejected rational expectations or by employing the encompassing principle partial adjustment adaptive expectations surprisingly all three forms have similar long run solutions since the short run dynamics differ substantially the results have important implications for the conduct of monetary policy

two illustrations of the quantity theory of money breakdowns and revivals by extending his data we document the instability of low frequency regression coefficients that lucas 1980 used to express the quantity theory of money we impute the differences in these regression coefficients to differences in monetary policies across periods a dsge model estimated over a subsample like lucas s implies values of the regression coefficients that confirm lucas s results for his sample period but perturbing monetary policy rule parameters away from the values estimated over lucas s subsample alters the regression coefficients in ways that reproduce their instability over our longer sample jel c51 e23 e31 e43 e51 e52 robert e lucas jr 1980 used near unit slopes of univariate regressions of moving averages of inflation and interest rates on money growth for the united states for the period 1953 1977 to illustrate two central implications of the quantity theory of money that a given change in the rate of change in the quantity of money induces i an equal change in the rate of price inflation and ii an equal change in nominal rates of interest lucas said that those two quantity theoretic propositions

liquidity a new monetarist perspective this essay surveys the new monetarist approach to liquidity work in this literature strives for empirical and policy relevance plus rigorous foundations questions include what is liquidity is money essential in achieving desirable outcomes which objects can or should serve in this capacity when can asset prices differ from fundamentals what are the functions of commitment and collateral in credit markets how does money interact with credit and intermediation what can and should monetary policy do the research summarized emphasizes the micro structure of frictional transactions and studies how institutions like monetary exchange credit arrangements or intermediation facilitate the exchange process

relative prices in the uk personal sector money demand function nonparametric demand analysis is used in order to establish admissible monetary aggregates and also to establish a potential role for relative prices in the money demand function a conventional money demand specification is then contrasted with a money demand function which contains the relative prices of durables nondurables and services as additional regressors evidence from long run cointegration analysis short run error correction models and nonnested testing all confirm a role for relative prices in the u k personal sector s money demand function copyright 1996 by royal economic society

international evidence on misspecification of the standard money demand equation abstract this paper tests the proposition that the interest rate in the standard money demand equation acts as a proxy for the expected change in interest rates if this is true the interest elasticity in the standard equation will depend on the expectations process for interest rates using cross country data we find that there does exist a relationship between the observed interest elasticity in the standard equation and the predictability of future interest rates from current interest rates

the merit order effect of wind and photovoltaic electricity generation in germany 2008 2016 estimation and distributional implications abstract generation from renewable energy sources in germany has experienced a considerable uptake in recent years mainly responsible for this development is the german renewable energy sources act erneuerbare energien gesetz eeg this paper considers redistributive implications of the eeg for different electricity consumers using time series regression analysis we show that electricity generation by wind and pv has reduced spot market prices considerably by 6 mwh in 2010 rising to 10 mwh in 2012 we use these results to build a near term forecasting tool for merit order effects projected to reach 14 16 mwh in 2016 on the other hand the costs of the eeg are passed forward to consumers in the form of a surcharge our findings highlight significant redistributive transfers under the current design of the eeg in particular some energy intensive industries are benefiting from lower wholesale electricity prices whilst being largely exempted from contributing to the costs of the scheme we also highlight implications of our results for other areas for reform of the eeg such as adequate remuneration mechanisms that ensure efficient operation and investment decisions are made under the scheme more generally these findings suggest that policy makers need to integrate distributional assessments into policy design and implementation
