multiple solution indeterminacies in monetary policy analysis abstract a sizeable fraction of recent research on monetary policy has been concerned with issues relating to analytical indeterminacies i e multiple solutions in rational expectations re models most of the literature features sophisticated re analysis conducted within dynamic models that reflect optimizing behavior by individual agents and incorporate taylor style policy rules a few papers have suggested that some of the particular indeterminacy arguments are misleading or irrelevant for the most part however there has been little dissent from the position that these indeterminacies present a genuine problem for monetary policy makers the purpose of the present paper by contrast is to argue that conclusions based on multiple solution indeterminacy findings are of dubious merit rather generally

fertility volatility and growth abstract empirically growth rates are negatively correlated with birth rates they are also correlated with production risk we argue that these stylized facts are related and arise jointly from the decision of how many children to have in a risky environment

risk the financial market and macroeconomic equilibrium growing recognition of the importance of stock market phenomena to the real economy underscores the need for models linking exogenous uncertainty asset market performance and the rest of the economy in an optimizing framework without certainty equivalence this paper constructs a three agent model with continuous time stochastic variables uncertain private production and government expenditure and forward looking rational agents the growth rate of output physical capital accumulation financial asset returns and uncertain inflation are determined as functions of the exogenous uncertainty in the economy analysis of the model finds that increased risk associated with government policy often reverses in an explainable way the conventional comparative static predictions of nonstochastic macro models

monetary and fiscal theories of the price level the irreconcilable differences the fiscal theory of the price level ftpl has attracted much attention but disagreement remains concerning its defining characteristics some writers have emphasized implications regarding interest rate pegging and determinacy of rational expectations solutions whereas others have stressed its capacity to generate equilibria in which price level trajectories mimic those of bonds and differ drastically from those of money supplies we argue that the ftpl attained prominence precisely because it appeared to provide a theory whose implications differ greatly from conventional monetary analysis accordingly we review monetarist writings to identify the primary distinctions in addition we review recent findings concerning learnability and therefore plausibility of competing rational expectations equilibria these indicate that when ftpl and monetarist equilibria differ the latter are more plausible in the vast majority of cases under ricardian assumptions necessary for clear distinctions theoretical analysis indicates that fiscal and monetary coordination is not necessary for macroeconomic stability copyright 2005 oxford university press

money bonds and foreign exchange in the theory of finance capital markets provide securities which allow the ownership of productive assets to be allocated among investors according to their willingness to bear risk in exchange for return and independently of their tastes for the productive services provided by the assets this paper uses the theory of finance to study the role of money as a productive asset and the transformation of money into a portfolio asset true to its purpose the capital market provides securities nominal bonds that allow an allocation of the current services of the money supply according to its current productivity and without regard for its future purchasing power risk and an allocation of the future purchasing power risk of the money supply according to the willingness of investors to bear this risk in exchange for return and without regard for investor needs for the future transactions services of money in open

nominal rigidity and monetary uncertainty abstract a stochastic macromodel with dynamically optimising wage setting households is used to examine the effect on current macroeconomic variables of an anticipated increase in variability of the money stock there is a nominal rigidity in the form of a money wage set one period in advance in whose absence monetary uncertainty has no effect on current variables we show that for plausible parameterisations monetary uncertainty combined with nominal rigidity raises the nominal interest rate depressing aggregate demand and hence current price and output it also causes the wage to be set higher increasing the natural rate of unemployment

fiscal flows and financial markets to what extent do they provide risk sharing within sweden andersson l fiscal flows and financial markets to what extent do they provide risk sharing within sweden regional studies the objective of this paper is to analyse the amount of risk sharing that takes place between regions in sweden it is found that the capital market is the largest source of risk sharing of an exogenous change in gross regional product in sweden still roughly 20 of a change in regional output is smoothed among the regions through the fiscal system there is also some evidence that there are regional differences in the sense that regions located in the south rely more on the capital market as a source of insurance against shocks in output while the tax and transfer systems provide a larger extent of risk sharing for regions located in the north andersson l flux fiscaux et marches financiers dans quelle mesure assurent ils le partage de risques en suede regional studies l objet de cette communication est d analyser l importance du partage de risques entre regions suedoises

learning about monetary policy rules abstract we study macroeconomic systems with forward looking private sector agents and a monetary authority that is trying to control the economy through the use of a linear policy feedback rule we use stability under recursive learning a la evans and honkapohja learning and expectations in macroeconomics princeton university press princeton new jersey 2001 as a criterion for evaluating monetary policy rules in this context we find that considering learning can alter the evaluation of alternative policy rules

indeterminacy bubbles and the fiscal theory of price level determination abstract the recently developed fiscal theory of price level determination contends that there is an important class of policy rules in which there exists a unique rational expectations solution that shows the price level to be dependent upon fiscal policy and independent of monetary variables the present paper argues however that there is an alternative solution to these models that has entirely traditional or monetarist properties this latter solution is arguably more plausible since it is the solution that is typically regarded as the bubble free fundamentals solution the paper s analysis involves the specification of feasible instrument variables

on non uniqueness in rational expectations models an attempt at perspective abstract many macroeconomic models involving rational expectations give rise to an infinity of solution paths even when the models are linear in all variables some writers have suggested that this non uniqueness constitutes a serious weakness for the rational expectations hypothesis one purpose of the present paper is to argue that the non uniqueness in question is not properly attributable to the rationality hypothesis but instead is a general feature of dynamic models involving expectations it is also argued that there typically exists in a very wide class of linear rational expectations models a single solution that excludes bubble or bootstrap effects one that occur only because they are arbitrarily expected to occur a systematic procedure for obtaining solutions free from such effects is introduced and discussed in addition this procedure is used to interpret and reconsider several prominent examples with solution multiplicities including ones developed by fischer black and john b taylor

money as stock abstract the fiscal theory determines the price level from the value of nominal government debt as a claim to government primary surpluses just as private stock is valued as a claim to corporate profits valuation equations are not constraints so this theory does not mistreat the government s intertemporal budget constraint i anchor the analysis in a simple cash in advance model when money demand falls to zero i show that the price level can still be determined by the government debt valuation equation

monetary randomness and investment abstract this paper develops a neoclassical model in which the behavior of the money supply affects investment by affecting the real distribution of asset returns investment depends on wealthholders demand for capital a stochastic money growth rule influences portfolio choice by affecting the distribution of the inflation rate the variance of inflation matters to wealthholders because of the existence of assets with returns that are not indexed to changes in the price level money and bonds which are contracted in nominal terms in a rational expectations environment asset demands will thus be sensitive to the distribution of the money growth rate our principle conclusion is that an increase in the variance of the money growth rate lowers investment which complements tobin s 1965 result that an increase in the mean stimulates capital accumulation the paper also represents a step toward incorporating an asset market into a macroeconomic model in a manner which takes account of lucas 1976 criticism of econometric policy evaluation all variables in the model including asset return distributions are functions of technology preferences and the money supply rule further expectations are rational

money inflation and investment abstract this paper analyzes an infinite horizon optimizing monetary growth model with endogenously determined income tax rates the technology is linear and random and preferences exhibit unitary relative risk aversion and a constant elasticity of substitution between real money balances and consumption an explicit solution for the rational expectations equilibrium is derived the relationship between the money growth rate and investment depends on the elasticity of substitution moreover maximizing welfare is inconsistent with choosing a money growth rule to maximize investment

the macroeconomic role of fiscal policy this article examines the new consensus that fiscal policy should have no macroeconomic role in flexible inflation targeting regimes there is little basis for this presumption fiscal policy remains important in setting the policy mix and in managing shocks and imbalances the credibility of an inflation targeting regime should be enhanced rather than reduced if fiscal policy plays its proper role it is true nevertheless that the costs of focusing fiscal policy narrowly on public sector concerns may not be very great most of the time however when interest rates cannot be used the role of fiscal policy must be different with interest rates at their lower bound of zero there is no plausible alternative for asymmetric shocks and adjustments in emu fiscal policy needs ideally to substitute for the interest rate policy reaction function of the consensus but the difficulties are very great we suggest a policy focus on real exchange rates as a way of resolving some of the dilemmas there is a serious danger that orthodox views about fiscal policy drawn from the consensus will be inappropriately applied especially in europe copyright 2005 oxford university press

optimal government finance policy and exchange rate management in a stochastically growing open economy abstract optimal monetary policy is analyzed in a stochastic small open economy consisting of risk averse representative agents the analysis shows how optimal monetary policy should be directed toward an optimal interest rate target this target which maximizes the intertemporal utility of the representative agent is determined by balancing off the marginal gains of a higher interest rate on increased growth and the future consumption it generates against the marginal losses stemming from a reduction in the holdings of real money balances the paper shows how an appropriately set monetary growth rate eliminates the need for continuous intervention in the exchange market

regional risk sharing provided by the fiscal system empirical evidence from sweden andersson l 2004 regional risk sharing provided by the fiscal system empirical evidence from sweden reg studies38 269 280 the objective of this paper is to analyse risk sharing among municipalities in sweden in terms of how the central government smooths personal income via the tax and transfer systems using panel data for the period 1983 2001 we find that the national tax and transfer systems mitigate an adverse shock to income of 1 krona so that the disposable income falls by 90 ore on average however there are differences across regions where the effect on disposable income varies between 78 and 93 ore in the krona a sensitivity analysis of the stability of the estimates over time suggests that the adjustment of the rules of the transfer system in 1991 associated with the tax reform the same year may have influenced the importance of national transfers as a means of absorbing risk while the evidence of a structural break due to the tax reform itself is less conclusive andersson l 2

interest rates and monetary policy uncertainty abstract this paper analyzes a model in which optimizing households are uncertain about monetary policy and learn about it over time in this model the variance of changes in nominal and ex post real interest rates increases with the variance of the household s predictive distribution over money growth a positive relation between unexpected changes in nominal interest rates and the money stock results from monetary policy uncertainty finally if money growth covaries negatively with real wealth an increase in monetary policy uncertainty increases the expected real rate of interest and decreases the nominal rate of interest
