precautionary saving in the small and in the large the theory of precautionary saving is shown to be isomorphic to the arrow pratt theory of risk aversion making possible the application of a large body of knowledge about risk aversion to precautionary saving and more generally to the theory of optimal choice under risk in particular a measure of the strength of the precautionary saving motive analogous to the arrow pratt measure of risk aversion is used to establish a number of new propositions about precautionary saving and to give a new interpretation of the dreze modigliani substitution effect copyright 1990 by the econometric society

test of the adjustment process and linear homogeneity in a stock adjustment model of money demand stock adjustment models of money demand have employed either the nominal or real adjustment process but they have not been tested statistically due to their nonnestedness this paper formulates a general stock adjustment model which includes both nominal and real adjustment processes as its nested subsets each process is then tested against the general specification the paper also examines the homogeneity of money demand with respect to price level and income in the general model

standard risk aversion this paper introduces the concept of standard risk aversion a von neumann morgenstern utility function has standard risk aversion if any risk makes a small reduction in wealth more painful in the sense of an increased reduction in expected utility also makes any undesirable independent risk more painful it is shown that given monotonicity and concavity the combination of decreasing absolute risk aversion and decreasing absolute prudence is necessary and sufficient for standard risk aversion standard risk aversion is shown to imply not only pratt and zeckhauser s proper risk aversion individually undesirable independent risks always being jointly undesirable but also that being forced to face an undesirable risk reduces the optimal investment in a risky security with and independent return similar results are established for the effect of broad class of increases in one risk on the desirability of or optimal investment in a second independent risk

is the price level tied to the m2 monetary aggregate in the long run a long run link between money and prices is evident for the united states since the korean war if the m2 measure of money is used and the velocity of m2 v2 is modeled as a mean reverting series this link between m2 and prices is the basis for a dynamic model of inflation that compares favorably in forecasting exercises with phillips curve and more typical monetarist approaches the behavior of v2 is examined from 1870 to the present providing a basis for reconsidering previous findings that v2 follows a random walk copyright 1991 by american economic association

shocking the eurozone abstract in this paper the monetary transmission mechanism within the european monetary union is investigated the impulse response functions and forecast error variance decompositions of a structural vector error correction model svecm are compared with those of a new keynesian theoretical model the identifying restrictions of the svecm are directly derived from the theoretical model two permanent shocks are identified one having only nominal and one having only real effects the three transitory shocks comprise a short term interest rate shock an aggregate demand shock and a money demand shock the main conclusions are that permanently reducing the inflation objective depresses output in the first year but has no real effects in the long run regarding output variability the results indicate that aggregate demand shocks are most important during the first year after which aggregate supply shocks dominate

the quality of employment in india s services sector exploring the heterogeneity for some observers the dramatic growth of the services sector in india reflects rapid strides made by educated professionals some others see it as the expansion of an employer of last resort given this heterogeneity the object of this article is to analyse the quality of employment being created in different sub sectors of services relative to the industrial sector where quality is defined to include wages job security and social protection analysing household survey data from india in 1993 94 and 2004 05 we find the following first sub sectors of services are generally either good or bad employers higher wages do not compensate for less job security or less job protection second the classification of most service sub sectors as good or bad employers in 2004 05 is the same as that in 1993 94 third employment expansion during the 10 year period under consideration is more in service sub sectors where quality of employment is low

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

stock market downswing and the stability of european monetary union money demand this article analyzes the question whether money demand in the euro area underwent a structural change in the end of 2001 when m3 money growth started to considerably overshoot the reference value set by the european central bank it is found that conventional specifications of money demand have in fact become unstable whereas specifications that are augmented with equity returns and volatility remain stable using such an augmented specification it turns out that the high m3 growth rates have not led to excess liquidity and thus do not pose a measurable threat to price stability

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

optimal self protection in two periods on the role of endogenous saving self protection is a costly investment to reduce the probability of loss this paper studies optimal self protection in a two period model with endogenous saving in a setting with a binary loss we show that prudence is negatively associated with the optimal level of self protection consistent with results obtained in single period models we provide intuition for this finding with the help of a recent approach based on stochastic dominance furthermore we determine the effect of interest rate risk on optimal self protection and study a model in which a decision maker engages in advance effort to increase the probability of facing a better risky situation all our results suggest that the understanding of advance self protection crucially hinges on whether the decision maker also uses saving to optimize intertemporal consumption utility if so the fact that self protection expenditures are upfront turns out to be irrelevant

why do big firms pay higher wages evidence from an international database abstract bigger firms pay higher wages this note reports tests of the hypothesis that this big firm premium bfp occurs because workers in big firms are more skilled we use the international adult literacy survey which gives richer skill measures than those typically available in labor market surveys to measure the bfp in nine countries with and without controls for worker skill the results show that the bfp is not as universal as is often suggested but in countries where it exists controlling for skills does little to reduce the size of the bfp

the demand for money in eec countries abstract this paper examines the demand for money in the eec countries and is focussed on five issues first it starts form a common economic framework which allows for shifts from m 2 to non money assets and vice versa second special attention is given to the dynamic structure of the statistical model in order to obtain meaningful conclusions on e g the speed of adjustment of actual to optimal money holdings third the study is entirely based on a uniform set of quarterly data for the eight countries concerned fourth the paper presents a careful examination of the residuals and finally analyses the predictive behaviour of the estimated models for all countries we found long run income elasticities greater than unity and interest rate elasticities clustered around 0 20 the impact of inflation and the business cycle variable appeared to be significant in the majority of countries considered

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

long run estimates of money demand new evidence from east asian countries and the presence of structural breaks conventionally the money demand function is estimated using a linear regression of the logarithm of money demand on a number of variables in this article we aim to estimate the long run properties of money demand specification for a number of east asian economies and within a panel framework with the presence of structural breaks various country specific coefficients are allowed to capture inter country heterogeneities consistent with theoretical postulates it is found that a the demand for money in the long run positively responds to real income and inversely to the interest rate spread inflation the real effective exchange rate and the us real interest rate b the long run income elasticity is greater than unity and c both the currency substitution and capital mobility hypotheses hold the empirical findings in this article can provide useful policy guidelines to the east asian countries central banks in their quest for price stability if one of the primary objectives of these countries

higher order generalizations of arrow pratt and ross risk aversion a comparative statics approach abstract we analyze comparative risk aversion in a new way through a comparative statics problem in which for a cost agents can shift from an initial probability distribution toward a preferred distribution the ross characterization arises when the original distribution is riskier than the preferred distribution and the cost is monetary and the arrow pratt characterization arises when the original distribution differs from the preferred distribution by a simple mean preserving spread and the cost is a utility cost higher order increases in risk lead to higher order generalizations and the comparative statics method yields a unified approach to the problem of comparative risk attitudes

the two pillars of the european central bank i interpret the european central bank s two pillar strategy by proposing an empirical model for inflation that distinguishes between the short and long run components of inflation the latter component depends on an exponentially weighted moving average of past monetary growth and the former on the output gap estimates for the 1971 2003 period suggest that money can be combined with other indicators to form the broadly based assessment of the outlook for future price developments that constitutes the ecb s second pillar however the analysis does not suggest that money should be treated differently from other indicators while money is a useful policy indicator all relevant indicators should be assessed in an integrated manner and a separate pillar focused on monetary aggregates does not appear necessary stefan gerlach

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

a money demand system for euro area m3 in order to assess the importance of monetary and financial developments for key macroeconomic variables in the euro area a money demand system for m3 is estimated adopting a structural cointegrating var approach while maintaining a good statistical representation of the data long run relationships are based on economic theory by using generalized response profiles the dynamics of the money demand system is investigated without any further identifying assumptions error bounds of the profiles are derived using bootstrap simulations

investigating m3 money demand in the euro area new evidence based on standard models monetary growth in the euro area has exceeded its target level especially since 2001 likewise recent empirical studies did not find evidence in favour of a stable long run relationship between the variables entering the money demand function instead the equation appears to be increasingly unstable if more recent data are included since the link between money balances and macroeconomic variables seems to has become rather fragile these results put serious doubts concerning the rationale of monetary aggregates in the monetary policy strategy of the ecb however if the analysis is done without imposing a short run homogeneity restriction between money and prices a stable long run money demand relationship can be identified where recursively estimated parameters are almost stable in addition the corresponding error correction model survives a wide array of specification tests including procedures for nonlinearities and parameter instability hence the apparent monetary overhang is in line with standard models of money demand behaviour and is not expected to lead to a rise in inflation

country characteristics and the effects of government consumption shocks on the current account and real exchange rate abstract this paper examines the effects of government consumption shocks on the current account and the real exchange rate as well as the influence of various country characteristics on these effects a dataset of 18 industrial countries is used for the analysis panel var models are estimated for the groups of countries classified by country characteristics the primary empirical findings are as follows first positive government consumption shocks lead if anything to real exchange rate depreciation but the direction of the current account response varies across samples in particular positive government consumption shocks lead to real exchange rate depreciation under a floating exchange rate regime second international capital mobility has a significant impact on the effects of government consumption shocks the depreciation of the real exchange rate and the improvement of current account are larger in countries with low international capital mobility than those with high capital mobility third albeit less robust the depreciation of the real exchange rate and the improvement of the current account are larger in countries under more flexible exchange rate regimes than those under less flexible exchange rate regimes in addition the current account improves more in countries with high trade openness than those with low trade openness standard theories do not fully explain these empirical patterns thus these findings suggest a need for further theoretical development

the dynamic effects of aggregate demand and supply disturbances we interpret fluctuations in gnp and unemployment as due to two types of disturbances disturbances that have a permanent effect on output and disturbances that do not we interpret the first as supply disturbances the second as demand disturbances demand disturbances have a hump shaped mirror image effect on output and unemployment the effect of supply disturbances on output increases steadily over time peaking after two years and reaching a plateau after five years

segmented labour markets and the estimation of wage functions this paper uses a stratified random sample of private sector employees to estimate wage equations for both the male labour market as a whole and six segments of the labour market segement which are defined with respect to the industry and size characteristics of the employing establishmen highly conventional results are obtained when wage equations are estimated for the male labour market as a whole or within two segements comprising almost half the survey population however one can reject conclusively the hypothesis that the same estimating equation is appropriate for modelling wage determination in all segments and if a human capital hk model is within segements tested against more appropriate alternative hypotheses for wage determination using the davidson and mackinnon 1981 methodology for the testing of non nested hypotheses the conclusion is that one should reject the hk specification and not reject the alternative it is therefore argued that the disaggregation of labour market dat

what does the bundesbank target abstract although its primary ultimate objective is price stability the bundesbank has drawn a distinction between its money focused strategy and the inflation targeting approach recently adopted by a number of central banks we show that holding constant the current forecast of inflation german monetary policy responds very little to changes in forecasted money growth we conclude that the bundesbank is much better described as an inflation targeter than as a money targeter an additional contribution of the paper is to apply the structural var methods of b bernanke and i mihov measuring monetary policy working paper no 5145 national bureau of economic research cambridge ma june 1995 to determine the optimal indicator of german monetary policy we find that the lombard rate has historically been a good policy indicator although the use of the call rate as an indicator cannot be statistically rejected

putting risk in its proper place this paper examines preferences toward particular classes of lottery pairs we show how such concepts as prudence and temperance can be fully characterized by a preference relation over these lotteries if preferences are defined in an expected utility framework with differentiable utility the direction of preference for a particular class of lottery pairs is equivalent to signing the nth derivative of the utility function what makes our characterization appealing is its simplicity which seems particularly amenable to experimentation

investigating stability and linearity of a german m1 money demand function starting from a linear error correction model ecm the stability and linearity of a german m1 money demand function are investigated applying smooth transition regression techniques using seasonally unadjusted quarterly data from 1961 1 to 1990 2 it is found that the money demand equation considered is both linear and stable after extending the sampling period until 1995 4 a clear structural instability due to the monetary unification on 1 july 1990 is found and subsequently modelled a non linear specification for the extended period is presented and discussed copyright 1999 john wiley sons ltd

long run money demand revisited evidence from a non linear approach abstract in this paper we argue that employing the conventional linear cointegration approach in examining long run money demand may not be appropriate after taking into account the existence of transaction costs we provide evidence to show that deviations from equilibrium money demand follow an exponential smooth transition autoregressive process that is mean reverting outside a given range and has a unit root inside the range our findings also provide an alternative explanation for the failure of much of the existing literature to support a long run money demand function

precautionary self insurance cum protection abstract precautionary self insurance cum protection sicp arises when an individual spends more on sicp when background risk is introduced we develop a two period model wherein additive multiplicative background risk prevails in the second period using the theory of monotone comparative statics and risk apportionment we derive necessary and sufficient conditions under which the individual spends more on sicp when the background risk deteriorates via higher order stochastic dominance prudence is called for to create a precautionary motive that induces the individual to shift his wealth in a way to reduce the loss of expected utility caused by the addition of background risk thereby giving rise to the precautionary sicp

a small estimated euro area model with rational expectations and nominal rigidities abstract we estimate a small model of the euro area to be used for evaluating alternative monetary policy strategies starting with the relationship between output and inflation we compare the fit of the nominal wage contracting model due to taylor j political econom 88 1980 1 and the relative real wage contracting model proposed by buiter and jewitt the manchester school 49 1981 211 reprinted in buiter ed macroeconomic theory and stabilization policy manchester university press manchester 1989 and estimated with u s data by fuhrer and moore quart j econom 110 1995 127 while fuhrer and moore reject nominal contracts in favor of relative contracts which induce more inflation persistence we find that both specifications fit euro area data reasonably well when considering france germany and italy separately however we find that nominal contracts fit german data better while the relative contracting model does well with respect to formerly high inflation countries such as france and italy we close the model by estimating an aggregate demand relationship and investigate the implications of nominal versus relative contracts for the inflation output variability tradeoff when monetary policy follows taylor s rule

on the aggregation of eurozone data abstract constructing eurozone aggregates is common practice in empirical studies this study shows that the choice of aggregation method does not only matter on a theoretical basis a brief study on eurozone money demand indicates the empirical importance of choosing the correct aggregation method as different aggregates give substantially different outcomes

money and inflation in the euro area a case for monetary indicators abstract this paper examines inflation indicators for the euro area by studying the relationship between inflation output money and interest rates using data spanning 1980 2001 the central finding is that both the output gap and the real money gap the difference between the real money stock and the long run equilibrium real money stock contain considerable information regarding future inflation in contrast the eurosystem s money growth indicator the difference between nominal money growth and a reference value the prominent first pillar in its monetary strategy contains little information about future inflation and no information beyond that contained in the output and real money gaps the predictive performance of the output gap has improved compared to that in a previous version of this paper most likely because of better estimation methods

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

microfoundations for a stable demand for money function scientific revolutions seldom occur when the prevailing theories appear to be performing well it is only when the accepted theory fails to offer a satisfactory explanation of events that new and more robust theories are proposed of these new theories the one which can explain the successful performance of the previous theory and also the events which led to its demise becomes the replacement so it is in the history of modern monetary economics the failure of the partial adjustment model in the mid s is well documented in the united kingdom and the united states and the search for a replacement has been the main point on the agenda since that time there are many contending theories some of which are advocated by the other contributors to this controversy but the mark of a truly better theory which can be claimed to supersede the partial adjustment model is one that can explain the success and the breakdown of the previous theory as well as the events subsequently central to the argument of this paper is the importance of individual behaviour in the context of a market for monetary assets only by means of careful investigation of the microeconomic behaviour underpinning monetary economics at the individual and the market level can the stability of the money demand function be restored it is the purpose of this paper to suggest that the buffer stock approach has gone further than other approaches in dealing with the fundamental micro foundations of the demand for money it does not suggest that other approaches have no microfoundations but they tend to concentrate exclusively on specific aspects of the micro structure such as separability and ignore others relating to the behaviour of individual optimisers in a monetary market the buffer stock model has firm micro foundations which can explain the events both before and after the breakdown of the partial adjustment model section i provides an historical background to the debate and section ii gives a brief overview of buffer stock models which shows that unlike other approaches they have been able to reconcile the past success of the partial adjustment model with its present failure the nature of the microfoundations of buffer stock models are the source of the success and are discussed in more detail in section iii the final section evaluates the buffer stock approach in the light of the other alternatives

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

impulse response analysis of cointegrated systems abstract impulse response or dynamic multiplier analysis of vector autoregressive systems with cointegrated variables is considered the asymptotic distribution of the responses estimated with johansen s 1988 maximum likelihood procedure is derived the results are illustrated with an analysis of a west german money demand system the investigation shows that a direct interpretation of the cointegration relations may be difficult or misleading thereby the virtue of impulse response analysis for applied work is illustrated

risk lovers and the rent over investment puzzle in this paper we prove existence and uniqueness of equilibrium in a rent seeking contest given a class of heterogeneous risk loving players we explore the role third order risk attitude plays in equilibrium and find that imprudence is sufficient for risk lovers to increase rent seeking investment above the risk neutral outcome moreover we show that rent can be fully dissipated in a standard tullock contest played by a large number of risk lovers

risk aversion and the propensities for self insurance and self protection for a risk averse individual the methods for reducing the expected financial impact of a loss include reducing the severity of any loss that occurs self insurance and reducing the probability of the occurrence of a loss self protection the literature on this topic has pointed to several anomalies whereby the use of self protection and self insurance yield quite unsimilar results for example ehrlich and becker 5 show that self insurance is always a substitute for market insurance an insurance company s indemnifying a loss whereas self protection and market insurance might be complements dionne and eeckhoudt 4 show that a more risk averse consumer would always invest more in self insurance activities but not necessarily more in self protection activities they argue 4 42 that this result is counterintuitive and provides an exception to the widely accepted result that increased risk aversion reduces risky activities ehrlich and becker 5 639 argue that the incentive to self protect is not so dependent on attitude towards risk both of the above papers seem to take for granted that self protection activities reduce the riskiness of the final wealth distribution however as we argue below this is not the case if riskiness is defined as in rothschild and stiglitz 14 even if we use the variance as our risk measure we do not always reduce risk via self protection dionne and eeckhoudt suggest that these results might not be robust enough to extend to models that incorporate random initial wealth risk and state dependent preferences we show that the model seems to be very robust we also explain why self protection is not at all an exception to the long standing result of arrow 1 whereby more risk averse individuals undertake a lower

a traditional interpretation of macroeconomic fluctuations under the traditional interpretation of macroeconomic fluctuations aggregate demand shocks move output and prices in the same direction while aggregate supply shocks move output and prices in opposite directions this paper examines the joint behavior of u s output unemployment prices wages and nominal money and asks whether it is consistent with this interpretation the answer is a qualified yes

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

how well does the is lm model fit postwar u s data postwar u s time series for money interest rates prices and gnp are characterized by a multivariate process driven by four exogenous disturbances those disturbances are identified so that they can be interpreted as the four main sources of fluctuations found in the is lm phillips curve model money supply money demand is and aggregate supply shocks the dynamic properties of the estimated model are analyzed and shown to match most of the stylized predictions of the model the estimated decomposition is also used to measure the relative importance of each shock to interpret some macroeconomic episodes and to study sources of permanent shocks to nominal variables

dynamic risksharing in the united states and europe abstract we use a panel var model to improve upon the existing methodologies to analyze interregional risksharing and consumption smoothing channels first we endogenize the output process within a more general multi equation framework capturing the dynamic feedback between output and various smoothing channels second in line with dynamic general equilibrium open economy models of risksharing we exploit impulse response functions to trace the role of each smoothing channel over time in the presence of different structural shocks temporary vs permanent and output vs smoothing channels in the application to the us and oecd countries we find different dynamic properties of different smoothing channels we compare our results with the predictions of standard risksharing and consumption theories and tackle some of the puzzles in the literature such as the international risksharing puzzle and the consumption output correlation puzzle we are also able to address such policy issues as whether fiscal stabilizers have been substitutes or complements for financial market diversification activities and whether further financial market integration is likely to provide countries with more shock absorption tools a key result is the strong substitutability between capital and credit smoothing in the us and between fiscal and credit smoothing in the oecd

euro area money demand and international portfolio allocation a contribution to assessing risks to price stability this chapter argues that a stable broad money demand for the euro area over the period 1980 2011 can be obtained by modelling cross border international portfolio allocation we first observe that in this first decade of the new millennium the breakdown of standard money demand specifications for the euro area and the strong developments in annual m3 growth coincide with large net flows in portfolio invest ment in the euro area we then estimate a new money demand which turns out to be stable by including variables explaining portfolio flows omitted in the traditional specifications

modeling the demand for m3 in the unified germany an error correction model for the demand for real m3 money is constructed for the period of 1976 1994 with real gnp the gnp deflator as well as a short term and a long term interest rate as explanatory variables quarterly seasonally unadjusted data are used in estimating the model it is found that there is a clear structural break due to the german unification in 1990 on the other hand once this structural break is accounted for a stable relation is found which resists a series of specification tests these include a number of recent tests of parameter constancy and linearity our specification is at variance with findings reported by some other researchers notably the deutsche bundesbank

the monetary utility premium and interpersonal comparisons the utility premium is generally defined as the pain or reduction in expected utility caused by an nth degree risk increase where n 2 while it is a very useful concept in understanding a decision maker s choice in uncertain situations the utility premium is not interpersonally comparable this note shows that the monetary utility premium the utility premium divided by the expected marginal utility at the random starting wealth is interpersonally comparable and the comparison is characterized by ross more risk aversion of the corresponding degree

international money supply and real estate risk premium the case of the london office market abstract the main purpose of this study is to deeply investigate the determinants of the risk premium for the central london market between q2 2002 and q3 2015 using a vector autoregression var model we shed new light on the role of central banks in the historical level of the commercial real estate risk premium indeed since the global financial crisis gfc central banks have used unconventional monetary policies increasing the quantity of money available in the economy and creating structural changes therefore we have described the link between monetary policies and real estate using a theoretical is lm mundell fleming framework for a small open economy with a flexible exchange rate to empirically explore this phenomenon we have constructed a monetary index adapted to the office market we find that throughout the whole period 2002 2015 the vacancy rate the employment in services the ftse 100 the new monetary index and the autoregressive parameter are the main determinants of the historical risk premium however this result hides the complex realities of different sub periods finally we study the structural changes introduced by the monetary policy using a structural var model and impulse response function

tax rate uncertainty factor supplies and welfare uncertainty about prospective changes in tax rates may increase factor supplies and hence the tax base permitting a reduction in tax rates that could result in a net increase in welfare under empirically relevant assumptions about attitudes towards risk we find that when an individual exclusively saves or works the tax base rises in response to greater tax rate uncertainty so that welfare could indeed increase however when an individual both saves and works the supply of the randomly taxed factor declines with increased uncertainty implying that tax revenue and welfare decrease when the nonrandom tax rate is sufficiently low

substituting one risk increase for another a method for measuring risk aversion abstract this paper defines the rate of substitution of one stochastic change to a random variable for another it then focuses on the case where one of these changes is an nth degree risk increase and the other is an mth degree risk increase where n m 1 the paper shows that the rate of substitution for these two risk increases can be used to provide a broader definition and two additional characterizations of the nth degree ross more risk averse partial order the implications for local intensity measures of nth degree risk aversion are also examined the analysis organizes the existing results as well as generates new ones

comparative higher order risk aversion and higher order prudence abstract in this paper we define the n th degree utility premium as the pain associated with facing the passage from a more favorable risk to a less favorable risk where the risk increase is specified by the notion of more n th degree risk we further define the n th degree prudence utility premium as the increase in pain when the individual suffers a sure loss we show that the n th degree utility premium normalized by the n 1 th derivative of the utility function evaluated at the initial wealth can explain comparative risk aversion of higher orders on the other hand the n th degree prudence utility premium normalized by the n th derivative of the utility function evaluated at the initial wealth can explain comparative prudence of higher orders

european inflation dynamics abstract we provide evidence on the fit of the new phillips curve npc for the euro area over the period 1970 1998 and use it as a tool to compare the characteristics of european inflation dynamics with those observed in the u s we also analyze the factors underlying inflation inertia by examining the cyclical behavior of marginal costs as well as that of its two main components namely labor productivity and real wages some of the findings can be summarized as follows a the npc fits euro area data very well possibly better than u s data b the degree of price stickiness implied by the estimates is substantial but in line with survey evidence and u s estimates c inflation dynamics in the euro area appear to have a stronger forward looking component i e less inertia than in the u s d labor market frictions as manifested in the behavior of the wage markup appear to have played a key role in shaping the behavior of marginal costs and consequently inflation in europe

the price puzzle in the monetary transmission vars with long run restrictions abstract this study addresses the price puzzle a positive response of prices to monetary tightening in var models by using long run instead of the usual short run restrictions on the us data including output prices and interest rate we find that monetary tightening had a negative effect on prices

some stronger measures of risk aversion in the small and the large with applications the arrow pratt measures of risk aversion for von neumann morgenstern utility functions have become workhorses for analyzing problems in the microeconomics of uncertainty they have been used to characterize the qualitative properties of demand in insurance and asset markets to examine the properties of risk taking in taxation models and to study the interaction between risk and life cycle savings problems to name just a few applications equally importantly they have generated the linear risk tolerance class of utility functions which has provided canonical examples in such diverse areas as portfolio theory and the theory of teams despite these successes there have been a number of areas for which the results have been weaker than hoped it is natural to use the risk aversion measures to compare the behavior of individuals in risky choice situations for example consider the individual portfolio choice problem in a two asset world with a riskless asset and a risky asset if individual a has a uniformly higher arrow pratt coefficient of risk aversion than individual b then b will always choose a portfolio combination with more wealth invested in the risky asset but suppose that both assets are risky now there is no obvious sense in which the more risk averse individual can be said to hold a less risky portfolio but it seems strange that such a simple alteration should destroy the analytics which support the basic intuition similarly consider the basic insurance problem if one individual a is more risk averse than another b in the arrow pratt sense it follows that a will pay a larger premium to insure against a random loss than will b typically though an individual evaluates partial rather than total insurance that is only some gambles can be insured against and others must be retained in this case even when the gambles which are retained are independent from those which are insured it is no longer true that the individual whose arrow pratt measure of risk aversion is higher will pay a larger insurance premium the situation is no better when we consider comparative statics exercises for a single individual decreasing absolute risk aversion in the sense of arrow and

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

exchange rate predictability and monetary fundamentals in a small multi country panel in this paper a panel of vector error correction models based on a common long run relationship is utilized to test whether the euro exchange rates of canada japan and the united states have a long run link with monetary fundamentals we use both exchange relationships relative to the full emu area with synthetic aggregates for the pre emu period and relative to germany solely compared to existing cointegration frameworks our approach provides more evidence that the aforementioned exchange rates are consistent with a rational expectations based monetary exchange rate model based on a common long run relationship albeit with a long run impact of relative income that is higher than predicted by the theory as a next step we analyze the out of sample fit of this common long run exchange rate model relative to naive random walk based forecasts these forecasting evaluations indicate that the monetary fundamentals based common longrun model is superior to both random walk based forecasts and standard cointegrated var model based forecasts especially at horizons of 2 to 4 years

how much has labour taxation contributed to european structural unemployment abstract we analyse the effect of labour taxes on euro area unemployment making use of the blanchard and katz 1999 wage dynamics reconciling theory and evidence american economic review 89 2 69 74 nairu model we represent structural unemployment as that made up of two elements an observed part related to labour taxes plus a non stationary unobservable component related to the reservation wage and to the wage mark up contrary to empirical estimates available so far this modelling explicitly acknowledges the existence of non measurable factors responsible for the unemployment non stationarity for the period 1970 2004 we obtain a tax effect that lies in the middle of the estimates that can be found in the literature this study gives support to the view that lowering labour taxes can help to reduce unemployment in continental europe

inter industry and occupational wage differentials in italy the vast literture on wage determination in the post war era extensively documents the existence of large and persistent wage differentials among industries and workers of comparable skills this paper addresses the issue of wage dispersion in the context of the italian economy the stability over time of industry relative wages confirme previous results obtained for the other countries a wide class of earings equations is estimated using microdata for the italian manufacturing industry the results provide little evidence in support of the view that wage dispersion can be explained by either unmeasured workers charcteristics or by compensating wage differentials conversely the estimated pattern of industry occupation wage differentials is consistent with the existence of rent sharing mechanisms and fairness considerations

m3 money demand and excess liquidity in the euro area recent empirical studies have found evidence of unstable long run money demand functions if recent data are used if the link between money balances and the macroeconomy is fragile the rationale of monetary aggregates in the ecb strategy has to be doubted in contrast we present a stable long run money demand relationship for m3 for the period 1983 2006 to obtain the result the short run homogeneity restriction between money and prices is relaxed and a break in the income elasticity of money demand after 2001 is taken into account measures of excess liquidity do not show significant inflation pressures

the utility premium of friedman and savage comparative risk aversion and comparative prudence we show that the utility premium of friedman and savage can be used to explain comparative risk aversion and comparative prudence more precisely we show that the greater the risk aversion measure the greater a risk s utility premium normalized by the marginal utility and that the greater the prudence measure the greater the utility premium for disaggregating a certain loss of wealth and a zero mean risk normalized by the utility function s second derivative

money demand in euroland abstract this paper explores the determinants of alternative monetary aggregates in euroland a sample consisting of quarterly data covering the 1980 1 1998 4 period is considered we are interested whether a conventionally defined money demand equation is stable in some aggregates as opposed to others both long run and short run relationships are considered in this paper overall the results indicate that broad narrow money demand in euroland is a stable unstable function of euroland wide income and interest rates

stochastic dominance analysis without the independence axiom we characterize the consistency of a large class of nonexpected utility preferences including mean variance preferences and prospect theory preferences with stochastic orders for example stochastic dominances of different degrees our characterization rests on a novel decision theoretic result that provides a behavioral interpretation of the set of all derivatives of the functional representing the decision maker s preferences as an illustration we consider in some detail prospect theory and choice acclimating preferences two popular models of reference dependence under risk and we show the incompatibility of loss aversion with prudence this paper was accepted by james smith decision analysis

the story of the moment risk averse cypriot farmers respond to drought management this article illustrates the importance of estimating risk preferences when evaluating water policy using agricultural production data from the kiti region of cyprus we estimate farmers risk preferences a la antle journal of business and economic statistics 1 192 201 1983 american journal of agricultural economics 69 509 22 1987 and show sensitivity to higher order moments of profit such as skewness we show that farmers in the kiti region are risk averse with risk premiums in the region of 20 of expected profit we use these estimates to analyse the impact of a water quota from the perspective of three policy makers who differ only in their understanding of farmers risk preferences we show in the case of kiti that policy makers who model risk preferences incorrectly that is either a assume risk neutrality or b ignore down side risk wrongly predict the magnitude and direction of input responses and therefore the magnitude of welfare changes this highlights the importance of accomm

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

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

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

returns to investment in education a global update the author updates compilations of rate of return estimates to investment in education published since 1985 and discusses methodological issues surrounding those estimates some key patterns among the three main levels of education primary education continues to exhibit the highest social profitability in all world regions private returns are considerably higher than social returns because of the public subsidization of education the degree of public subsidy increases with the level of education which is regressive social and private returns at all levels generally decline by the level of a country s per capita income overall the returns to female education are higher than those to male education but at individual levels of education the pattern is more mixed the returns to the academic secondary school track are higher than the vocational track since unit cost of vocational education is much higher and the returns for those who work in the private competitive sector of the economy are higher than in the public noncompetitive sector and the returns in the self employment unregulated sector of the economy are higher than in the dependent employment sector controversies in the literature are discussed in the light of the new evidence the undisputable and universal positive correlation between education and earnings can be interpreted in many ways the causation issue on whether education really affects earnings can be answered only with experimental data generated by randomly exposing different people to various amounts of education given the fact that moral and pragmatic considerations prevent the generation of such pure data researchers have to make do with indirect inferences or natural experiments some have been attempted the author looks at the research on overeducation or surplus schooling the conclusions reinforce earlier patterns they confirm that primary education continues to be the number one investment priority in developing countries they also show that educating females is marginally more profitable than educating males that the academic secondary school curriculum is a better investment than the technical vocational tract and that the returns to education obey the same rules as investment in conventional capital that is they decline as investment is expanded
