the inflation tax in a real business cycle model money is incorporated into a real business cycle model using a cash in advance constraint the model economy is used to analyze whether the business cycle is different in high inflation and low inflation economies and to analyze the impact of variability in the growth rate of money in addition the welfare cost of the inflation tax is measured and the steady state properties of high and low inflation economies are compared

banking panics information and rational expectations equilibrium this paper shows that bank runs can be modeled as an equilibrium phenomenon we demonstrate that some aspects of the intuitive story that bank runs start with fears of insolvency of banks can be rigorously modeled if individuals observe long lines at the bank they correctly infer that there is a possibility that the bank is about to fail and precipitate a bank run however bank runs occur even when no one has any adverse information extra market constraints such as suspension of convertibility can prevent bank runs and result in superior allocations banking panics were a recurrent phenomenon in the united states until the 1930s they have re emerged as a source of public concern and much theoretical research recently in this paper we provide an information theoretic rationale for bank runs the traditional story is that contagion is an important aspect of bank runs the idea seems to be that when the general public observes large withdrawals from the banking system fears of insolvency grow resulting in even larger withdrawals of deposits in our model some individuals withdraw because they get information that future returns are likely to be low uninformed individuals observing this also have an incentive to liquidate their investments in addition some individuals need to withdraw deposits for other than informationally based reasons thus if the random realization of such a group of individuals is unusually large then the uninformed individuals will be misled and will precipitate a run on the bank the technology is such that a large volume of withdrawals involves liquidation costs consequently runs on the bank do impose social costs a mechanism that may reduce these costs in our model is to suspend convertibility if withdrawals are high however those individuals who need to withdraw their assets for liquidity reasons are worse off ex post our model provides a rationalization for restrictions in demand deposits that were widespread prior to 1929 friedman and schwartz 7 suggest that restrictions of payments ensured

optimality of the friedman rule in an overlapping generations model with spatial separation recent models with spatial separation and limited communication suggest that the friedman rule may not be optimal this is important in light of the disparity between theory and practice concerning optimal monetary policy we take a close look at these models and show that intergenerational transfers are key to the suboptimality of the friedman rule the friedman rule is a necessary condition for achieving the efficient allocation in equilibrium we also show that the friedman rule is chosen whenever agents can implement mutually beneficial arrangements

inter factor inter fuel substitution carbon intensity and energy related co2 reduction empirical evidence from china carbon dioxide co2 reduction which is the central issue in addressing global warming depends on the extent that clean energy can substitute for co2 emitting coal and non energy factors can substitute for energy factor the purposes of this paper are to empirically investigate inter factor inter fuel substitution in china and to evaluate the determinants of china s energy related carbon intensity as well as mitigation effects of carbon tax considering china s rapid increase in energy consumption and the slow adjustment in substitution the two stage estimation method and the dynamic error correction mechanism are employed in this study the empirical results suggest substitutability among different types of energy sources as well as substitutability among energy labor and capital the magnitude of cross price elasticities indicates that the substitutions are inelastic which limits the scope of the chinese government to implement substitution strategy aiming at energy conservation and environmental management china s carbon intensity declined during 1985 2012 most of which can be attributed to labor substitution and energy price increase however carbon intensive technology being embodied in china s capital investment energy consuming equipment has contributed to the increase in carbon intensity a carbon tax of rmb 50 tonne could reduce 332 9 million tonnes co2 emissions on the basis of 2012 in addition if ignoring the feedback between inter factor inter fuel substitutions co2 mitigation potential would be underestimated

residential energy demand in oecd countries and the role of irreversible efficiency improvements abstract after undergoing substantial changes during a period of high energy prices household energy demand did not rebound in times of declining energy prices as might have been expected hence other factors such as irreversible improvements in technical efficiency must be understood in order to describe both past and future household energy demand in this paper we consider irreversible efficiency improvements as a major reason for the moderate growth in energy demand after the plummeting of the oil price in 1985 we test different econometric models to take into account efficiency indicators the major conclusions of our investigation are i price elasticities are different for rising and falling prices for the latter they are close to zero implying a low rebound effect in the residential sector ii technical efficiency is an important parameter for describing and forecasting energy demand and iii income elasticities turn out to be higher once we incorporate indicators of technological efficiency in the process of estimating energy demand

india s missing girls biology customs and economic development we review the evidence on the sex ratio among children below the age of six international evidence shows that the sex ratio at birth is slightly biased towards boys but boys suffer greater mortality a pattern consistent with darwinian evolution with economic development the male bias in the child sex ratio increases south and east india show levels and trends in the child sex ratio that are consistent with this evidence however unbalanced sex ratios in the northern and western states since the first censuses indicate discrimination against girls technological developments permitting sex selective abortions have seriously aggravated the imbalances in these states economic modelling of parental choice regarding a child s gender suggests that gender imbalances may be consistent with individual maximization and marriage market equilibrium nevertheless these choices have adverse welfare consequences which will be aggravated by the decline in population growth and consequent relaxation of the marriage squeeze

inflation financial markets and long run real activity abstract empirical evidence suggests that real activity the volume of bank lending activity and the volume of trading in equity markets are strongly positively correlated at the same time inflation and financial market activity are strongly negatively correlated in the long run as are inflation and the real rate of return on equity inflation and real activity are also negatively correlated in the long run particularly for economies with relatively high rates of inflation we present a monetary growth model in which banks and secondary capital markets play a crucial allocative function we show that at least under certain configurations of parameters the predictions of the model are consistent with these and several other observations about inflation finance and long run real activity

accounting for asymmetric price responses and underlying energy demand trends in oecd industrial energy demand abstract this paper explores the way technical progress and improvements in energy efficiency are captured when modelling oecd industrial energy demand the industrial sectors of the developed world involve a number of different practices and processes utilising a range of different technologies consequently given the derived demand nature of energy it is vital when modelling industrial energy demand that the impact of technical progress is appropriately captured however the energy economics literature does not give a clear guide on how this can be achieved one strand suggests that technical progress is endogenous via asymmetric price responses whereas another strand suggests that it is exogenous more recently it has been suggested that potentially there is a role for both endogenous technical progress and exogenous technical progress and consequently the general model should be specified accordingly this paper therefore attempts to model oecd industrial energy demand using annual time series data over the period 1962 2010 for 15 oecd countries using the structural time series model framework the general specifications allow for both asymmetric price responses for technical progress to impact endogenously and an underlying energy demand trend for technical progress and other factors to impact exogenously but in a non linear way the results show that almost all of the preferred models for oecd industrial energy demand incorporate both a stochastic underlying energy demand trend and asymmetric price responses this gives estimated long run income elasticities in the range of 0 34 to 0 96 estimated long run price maximum elasticities in the range of 0 06 to 1 22 estimated long run price recovery elasticities in the range of 0 00 to 0 27 and estimated long run price cut elasticities in the range of 0 00 to 0 18 furthermore the analysis suggests that when modelling industrial energy demand there is a place for endogenous technical progress and an exogenous underlying energy demand trend consequently it is argued that any modelling strategy should start by including both and only imposed restrictions if accepted by the data

primary energy demand in japan an empirical analysis of long term trends and future co2 emissions abstract this paper examines the long run relationship between energy demand gnp and the real energy price in japan using data covering 1887 2001 it is found that if an underlying energy demand trend is appropriately incorporated the resulting econometric model produces a long run income elasticity of about unity and a long run price elasticity of about 0 2 the estimated model is utilised to forecast energy consumption and co 2 emissions up to 2012 it is shown that given current economic conditions and policies there is considerable uncertainty about whether japan will be able to meet its kyoto target by reducing co 2 emissions in 2008 2012 to the 1990 level it is shown that this uncertainty depends on the strength of the economy and leaves the japanese government with a difficult policy dilemma if there is a resurgence in growth to something near the annual average growth rate since the early 1980s a considerable effort will be required in order to meet its kyoto target requiring not only using the kyoto mechanisms but also additional tougher domestic policies and measures such as emissions capping r d incentives and education for energy conservation in addition to a pricing and tax policy

financial intermediation and endogenous growth an endogenous growth model with multiple assets is developed agents who face random future liquidity needs accumulate capital and a liquid but unproductive asset the effects of introducing financial intermediation into this environment are considered conditions are provided under which the introduction of intermediaries shifts the composition of savings toward capital causing intermediation to be growth promoting in addition intermediaries generally reduce socially unnecessary capital liquidation again tending to promote growth

stock markets and development this paper asks if financial development especially stock market development affects the level and or the growth rate of economic activity it finds a substantial effect on both current wisdom suggests that the growth effects of financial intermediation could be either permanent or transitory for instance the greenwood jovanovic 1990 henceforth gj model has an ak stucture with no diminishing returns to the reproducible factor and a permanent exogenous improvement in financial structure would cause a permanent increase in the rate of growth on the other hand if the returns to the reproducible factor did diminish better intermediation could lead only to level effects since one should not a priori exclude either growth effects or level effects we shall look for both our search for growth effects will use the gj model our search for level effects will rely on an amended version of the mankiw romer and weil 1992 henceforth mrw structure

heterogeneity redistribution and the friedman rule we study monetary models with nondegenerate stationary distributions of money holdings we find that the friedman rule does not typically maximize ex post social welfare an increase in the rate of growth of the money supply has two effects the standard distortionary or rate of return effect makes money a less desirable asset for all moneyholders a second redistributive effect creates a transfer from one type of agent to the other an increase in the rate of growth of money away from the friedman rule can produce a rate of return effect that dominates the standard effect

the long run relationship between inflation and output in postwar economies abstract we investigate the relationship between inflation and real output in a large sample of postwar economies our methodology is to use a structural vector autoregression to estimate the response of the level of real output to permanent inflation shocks separately for each country we find that a permanent shock to inflation is not associated with a permanent movement in the level of real output for most countries in our sample the main exceptions are certain low inflation countries in which permanent inflation shocks permanently increase the level of output we also find that permanent inflation shocks do not permanently influence real output growth rates in our sample

the imperfect price reversibility of non transport oil demand in the oecd abstract this paper examines the price reversibility of oecd non transport oil demand and its components residual heavy fuel oil non transport distillates and other non transport oil products our purpose is to determine the extent to which the reductions in demand following the oil price increases of the 1970s have been and will be reversed by the price cuts of the 1980s the analysis is based on an econometric model which utilizes price decomposition methods to measure separately the effects of price increases and price decreases these methods allow empirical testing of irreversibility and hysteresis and should be applicable in other areas of economics where asymmetry of response or persistence of effect are evident based on the statistical evidence we reject the conventional specification of demand being perfectly price reversible we conclude that the response to the price cuts of the 1980s has been significantly smaller than to the price increases of the 1970s demand has followed a ratchet process price increases reduced demand substantially when demanders conserved and switched away from oil but price cuts did not reverse this process completely if at all this has important implications for projections of oil demand especially under low price assumptions the oecd s dependency on oil will not increase as much as some analysts may have feared there is however another aspect of imperfect price reversibility the possibilities of adjusting to future price rises may not be as great as they have been in the past the easiest and least costly demand savings have already been made and oil has been replaced by other energy sources in many uses what s done is done

how good are standard debt contracts stochastic versus nonstochastic monitoring in a costly state verification environment the authors investigate ex ante efficient contracts in an environment in which implementation is costless in this environment standard debt contracts will typically not be optimal optimal contracts may involve defaults even in states in which the borrower is fully able to repay the authors then examine the welfare costs of arbitrarily restricting the set of feasible contracts to standard debt contracts when model parameters are calibrated to realistic values the welfare loss from exogenously imposing this restriction is extremely small thus if implementation costs are actually nontrivial as seems likely standard debt contracts will be very close to optimal copyright 1994 by university of chicago press

inflation and asset returns sustained inflation is detrimental to long run growth and the financial system a recent theoretical literature suggests that high inflation implies low real returns on assets these low returns exacerbate informational frictions interfering with the functioning of financial markets and the allocation of investment we investigate the plausibility of an inverse relationship between inflation and real returns inflation and nominal equity returns are negatively correlated or uncorrelated for all low to moderate inflation economies examined safe nominal rates of return and inflation are only weakly positively correlated however for high inflation economies inflation and nominal returns are strongly positively correlated

costly monitoring financial intermediation and equilibrium credit rationing abstract this paper establishes a link between equilibrium credit rationing and financial intermediation in a model with asymmetrically informed lenders and borrowers costly monitoring and investment project indivisibilities intermediation is shown to dominate borrowing and lending between individuals and these financial intermediaries exhibit several of the important features of intermediaries as we know them equilibrium interest rates and the aggregate quantity of loans respond quite differently to changes in taste and technology parameters depending on whether or not there is rationing in equilibrium

banking crises and liquidity in a monetary economy abstract this study investigates banks liquidity provision using the lagos and wright model of monetary exchange with aggregate uncertainty we show that banks sometimes exhaust their cash reserves and fail to satisfy their depositors needs for consumption smoothing we also show that banking crises can be eliminated by a rate of return equalizing policy under perfect risk sharing but the first best outcome can be only achieved with the friedman rule these results cannot be obtained with other monetary models e g overlapping generations models we also derive a rich array of non trivial effects of inflation on equilibrium deposits the probability of banking crises and banks portfolios

the optimal inflation tax when money reduces transactions costs abstract it has been argued that if money acts as an intermediate good the optimal inflation tax is zero this paper reexamines such a claim in the context of a model in which money reduces transactions costs it is shown that modeling money as an intermediate good does not necessarily imply that the optimal inflation tax is zero the optimality of a zero inflation tax depends on the properties of the transactions costs technology in particular if the transactions costs technology does not exhibit constant returns to scale it is optimal to resort to the inflation tax

dynamic multilevel modelling of industrial energy demand in europe previous studies of industry level energy demand have not accounted for the hierarchical nesting of industries within a system that also adequately allows for country specific determinants of energy demand the principal contribution of this paper is therefore to analyse energy demand for european industries over the period 1995 2009 using a dynamic multilevel model that accounts for this hierarchical data structure among other things we find firstly that our dynamic multilevel model suggests that if industry income and the industry energy price increase by 10 long run energy demand will increase by 8 1 and fall by 6 8 respectively secondly we find that the corresponding long run income and price elasticities are substantially larger in a standard dynamic model of industry level energy demand which does not account for the hierarchical data structure our results therefore suggest that not accounting for the hierarchical data structure results in unreliable estimates of energy demand elasticities from a policy perspective we argue that it is imperative that future industry level energy demand studies account for the hierarchical structure of the data this is to prevent energy policy making being based on industry level evidence that substantially inflates the responsiveness of long run energy demand to income and price changes

the conduct of monetary policy with a shrinking stock of government debt this article considers the consequences for a central bank of a declining stock of government debt the model has a treasury that taxes spends and issues debt a central bank that conducts open market operations in treasury debt and banks that intermediate private savings it suggests that a sufficiently small stock of debt can put an economy on the pareto inferior side of the seigniorage laffer curve implying unnecessarily high inflation if there is also a primary budget deficit equilibrium might not exist discount window lending is a potentially desirable alternative to open market operations especially if the loans are not subsidized

real income equivalence among one earner and two earner families in an earlier paper we proposed a technique for making income comparisons across various household sizes in this paper we employ a modified version of that method to convert nominal income to some real equivalent comparable across families of a given size but with one or two family earners we begin with a discussion of some of the conceptual difficulties involved in making cross family size or structure comparisons in income we then describe spending pattern differences between one and two earner families the final section discusses our effort to convert nominal income into comparable real income units we conclude that nominal income differences between two and one earner families far overstate differences in standards of living excerpt

technical change inter factor and inter fuel substitution possibilities in pakistan a trans log production function approach abstract energy consumption in pakistan increased significantly over the last two decades primarily due to industrialization in order to meet the growing energy needs the government adopted short term policies by setting up thermal power projects which are more expensive both in terms of fiscal cost and environmental damages as compared to hydro power projects the former has exposed pakistan to international oil price shocks and environmental degradations this study therefore attempts to analyze technical change using trans log production function by employing non energy factors i e capital and labor and energy factors i e petroleum and natural gas to estimate elasticity of substitution the purpose of the study is to provide policy suggestions to the government on how to achieve high economic growth vis a vis improved energy security and environmental sustainability the results reveal that capital energy and labor energy are substitutes thereby suggesting the need for an increased focus on technological advancement and skilled employment generation to conserve energy and reduce co 2 emission a gradual elimination of energy subsidies which will make energy price reflects its true cost is required to further discourage increased energy consumption and promote capital intensive production methods a scenario analysis based on the elasticity of substitution between capital energy and petroleum gas shows the potential of energy conservation and emission mitigation the results further suggest the importance of a diversified energy supply mix characterized by abundant hydro and other renewable energy resources alongside natural gas

the rising price of husbands a hedonic analysis of dowry increases in rural india dowries in south asia have steadily risen over the last 40 years and now often amount to over 50 percent of a household s assets this paper attempts to investigate the reasons behind this increase it adapts rosen s implicit market model to the indian marriage market and tests predictions from the model with data from six villages in south central india and from the indian census it is found that a marriage squeeze caused by population growth resulting in larger younger cohorts and hence a surplus of women in the marriage market has played a significant role in the rise in dowries

financial intermediation and regime switching in business cycles the authors study a one sector growth model where capital investment is credit financed and there is an adverse selection problem in credit markets the presence of adverse selection creates an indeterminacy of equilibrium many equilibria display permanent fluctuations characterized by transitions between walrasian regimes and regimes of credit rationing cyclical contractions involve declines in real interest rates increases in credit rationing and withdrawals of savings from banks for some configurations of parameters all equilibria display cyclical fluctuations the authors provide sufficient conditions for deterministic cycles consisting of m periods of expansion followed by n periods of contraction to exist copyright 1998 by american economic association

the optimum quantity of money rule in the theory of public finance this paper examines optimal tax policy in a monetary economy in which money serves as an intermediate good that helps facilitate the conversion of scarce resources into tinal consumption goods by enabling consumers to economize on the costs of transacting it is shown that in such an environment even though distorting taxes must be levied for revenue purposes the optimal tax structure calls for abstaining from inflationary finance and adopting the optimum quantity of money rule

distinguishing panics and information based bank runs welfare and policy implications in this paper we contrast panics and information based bank runs in an effort to provide a robust and empirically plausible model of how bank runs are triggered the model of information based runs is characterized by two sided asymmetric information the bank cannot observe the true liquidity needs of the depositors while depositors are asymmetrically informed about bank asset quality we also examine the relative degrees of risk sharing provided by bank deposit contracts and traded equity contracts we show that the choice of deposit or equity depends on the attributes of and information about the underlying investment returns

asset trading mechanisms and expansionary policy abstract previous authors have argued that the otimal monetary policy is contractionary if buyers value consumption substantially more than sellers there is some randomness and informational constraints make asset trading useful we show that there is an incentive compatible expansionary policy that dominates all incentive compatible contractionary policies

a nested ces approach to capital energy substitution abstract this paper uses the nested constant elasticity of substitution ces production function to estimate elasticities of substitution between capital labour energy and materials over the 1971 1976 period around the initial energy crisis elasticities are estimated for each of the two digit sic industries within us manufacturing using more disaggregate four digit sic data the nested ces function makes it possible to distinguish between engineering and economic elasticities of substitution capital and energy are estimated to be slight engineering substitutes and economic complements labour energy and materials are estimated economic substitutes

is the friedman rule optimal when money is an intermediate good in contrast to the recent literature on the optimal inflation tax we show that in models where money reduces transactions costs it is optimal to set the inflation tax to zero when seigniorage is replaced by revenue from distortionary taxes the main reasons for this result are that the variable costs of supplying real balances are negligible and the inflation tax is a unit tax we also show that the intermediate good optimal taxation rules in the public finance literature cannot be directly applied both when money is costless and when it requires resources to be produced

asymmetric price responses and the underlying energy demand trend are they substitutes or complements evidence from modelling oecd aggregate energy demand abstract a number of energy demand studies have considered the importance of modelling asymmetric price responses apr for example the often cited work of gately and huntington 2002 griffin and schulman 2005 questioned the asymmetric approach arguing that this is only capturing energy saving technical progress huntington 2006 however showed that for whole economy aggregate energy and oil demand there is a role statistically for both apr and exogenous energy saving technical change in a separate strand of the literature the idea of the underlying energy demand trend uedt has been developed see for example hunt et al 2003a and 2003b and dimitropoulos et al 2005 they argue that it is important in time series energy demand models to allow for stochastic trends or uedts based upon the structural time series dynamic regression methodology recommended by harvey 1989 1997 this paper attempts to bring these strands of the literature together by proposing a testing procedure for the uedt and apr in energy demand models within both a panel context consistent with the huntington 2006 approach and the structural time series modelling framework a set of tests across a range of specifications using time series and panel data are therefore suggested in order to try and ascertain whether energy saving technical change or the more general uedt and apr are substitutes for each other when modelling energy demand or whether they are actually picking up different influences and are therefore complements using annual whole economy data for 17 oecd countries over the period 1960 2006 the results suggest that for most of the countries the uedt is preferred to apr whereas for another group the uedt and apr are complements and for another group they are substitutes it is argued therefore that energy demand modellers should not assume at the outset that one method is superior to the other moreover wherever possible a general model be it in a time series or panel context that includes a non linear uedt and apr should be initially estimated and only if accepted by the data should symmetry and or a more restrictive uedt be imposed

currency elasticity and banking panics theory and evidence existing models of banking panics contain no role for monetary factors and fail to explain why some banking systems experienced panics while others did not a monetary model is constructed where seasonal variations in the demand for liquidity and credit play a critical role in generating banking panics these panics occur when there are restrictions on the issue of currency in private banks but they do not occur if banks are unrestricted empirical evidence from canada and the united states for the period 1880 1910 is largely consistent with the predictions of the model

daughters dowries deliveries the effect of marital payments on fertility choices in india abstract this paper investigates the effect of the differential pecuniary costs of sons and daughters on fertility decisions the focus is on dowries in india which increase the economic returns to sons and decrease the returns to daughters the paper exploits an exogenous shift in the cost of girls relative to boys arising from a revision in anti dowry law which is shown to have decreased dowry transfers markedly the reform is found to have attenuated the widely documented positive association between daughters and their parents fertility the effect is particularly pronounced for more autonomous women and for individuals living in areas characterised by strong preferences for sons

money intermediation and banking the business of money creation is conceptually distinct from that of intermediation yet these two activities are frequently but not always combined together in the form of a banking system we develop a simple model to examine the question when is banking essential there is a role for money due to a lack of record keeping and a role for intermediation due to the existence of private information both money and intermediation are essential when monitoring costs associated with intermediation are sufficiently low the two activities can be separated from one another however when monitoring costs are sufficiently high a banking system that combines these two activities is essential

banking crises in monetary economies this paper analyzes the effect of inflation on banking crises in a model in which money and banks play essential roles the model s equilibrium replicates some key features of actual banking crises namely the partial suspension of payments and the desire to hold cash even in the absence of pressing liquidity needs when banks have access to a stable foreign currency inflation has a threshold effect on banking crises higher inflation reduces the likelihood of crises when inflation is below the threshold the reverse happens when inflation exceeds the threshold this result appears to be broadly consistent with available evidence jel category e40 e50

modelling oecd industrial energy demand asymmetric price responses and energy saving technical change abstract the industrial sector embodies a multifaceted production process consequently modelling the derived demand for energy is a complex issue made all the more difficult by the need to capture the effect of technical progress of the capital stock this paper is an exercise in econometric modelling of industrial energy demand using panel data for 15 oecd countries over the period 1962 2003 exploring the issue of energy saving technical change and asymmetric price responses although difficult to determine precisely it is tentatively concluded that the preferred specification for oecd industrial energy demand incorporates asymmetric price responses but not exogenous energy saving technical change

energy intensity developments in 40 major economies structural change or technology improvement this study analyzes energy intensity trends and drivers in 40 major economies using the wiod database a novel harmonized and consistent dataset of input output table time series accompanied by environmental satellite data we use logarithmic mean divisia index decomposition to 1 study trends in global energy intensity between 1995 and 2007 2 attribute efficiency changes to either changes in technology or changes in the structure of the economy and 3 highlight sectoral and regional differences we first show that heterogeneity within each sector across countries is high these general trends within the sectors are dominated by large economies first and foremost the united states in most cases heterogeneity is lower within each country across the different sectors regarding changes of energy intensity at the country level improvements between 1995 and 2007 are largely attributable to technological change while structural change is less important in most countries notable exceptions are japan the united states australia taiwan mexico and brazil where a change in the industry mix was the main driver behind the observed energy intensity reduction

incomplete markets labor supply and capital accumulation we explore the accumulation of capital in the presence of limited insurance against idiosyncratic shocks borrowing constraints and endogenous labor supply in the exogenous labor supply case e g aiyagari 1994 huggett 1997 the presence of limited insurance increases the demand for savings for precautionary reasons as a consequence capital and output are higher under incomplete markets we show that if labor hours are endogenous labor supply is likely to be lower under incomplete markets because those agents who experience a high shock to productivity are ex post richer and they work fewer hours in some cases this wealth effect can overcome the aggregate precautionary savings and give rise to lower savings and output under incomplete

financial intermediation and delegated monitoring this paper develops a theory of financial intermediation based on minimizing the cost of monitoring information which is useful for resolving incentive problems between borrowers and lenders it presents a characterization of the costs of providing incentives for delegated monitoring by a financial intermediary diversification within an intermediary serves to reduce these costs even in a risk neutral economy the paper presents some more general analysis of the effect of diversification on resolving incentive problems in the environment assumed in the model debt contracts with costly bankruptcy are shown to be optimal the analysis has implications for the portfolio structure and capital structure of intermediaries

money banking and capital formation we consider a monetary growth model in which banks arise to provide liquidity in addition there is a government that issues not only money but interest bearing bonds these bonds compete with capital in private portfolios when the government fixes a constant growth rate for the money stock we show that there can exist multiple nontrivial monetary steady states one of these steady states is a saddle while the other can be a sink moreover paths approaching a steady state can display damped endogenous fluctuations and development trap phenomena are common across different steady states low capital stocks are associated with high nominal interest rates the latter signal the comparative inefficiency of the financial system also increases in the steady state inflation rate can easily reduce the steady state capital stock journal of economic literatureclassification numbers e13 e44 e50 g20 o16

the effects of open market operations in a model of intermediation and growth we examine an otherwise standard model of capital accumulation to which spatial separation and limited communication create a role for money and shocks to portfolio needs create a role for banks in this context we examine the existence multiplicity and dynamical properties of monetary equilibria with positive nominal interest rates moderate levels of risk aversion can lead to the existence of multiple monetary steady states all of which can be approached from a given set of initial conditions in addition even if there is a unique monetary steady state monetary equilibria can be indeterminate and oscillatory equilibrium paths can be observed thus financial market frictions are a potential source of both indeterminacies and endogenously arising economic volatility we also consider the consequences of monetary policy actions that rearrange the composition of government liabilities contractionary monetary policy activities can have complicated consequences depending especially on the nature of the steady state equilibrium that obtains when there are multiple steady states under plausible conditions however a permanent contractionary change in monetary policy raises both the nominal rate of interest and the rate of inflation and reduces long run output levels thus liquidity provision by a central bank just as by the banking system as a whole can be growth promoting loose monetary policy also is conducive to avoiding development trap phenomena

payments systems design in deterministic and private information environments abstract the first setup we study is a deterministic model with spatial separation where we consider alternative payments systems institutions and their implications for allocation and welfare a payments system with period by period settlement in outside money improves on decentralized exchange an efficient allocation is supported by a payments system where settlement is not imposed in the second model there is random matching and unobserved productivity shocks and preference shocks we explore how risk should be shared optimally in this economy and interpret the results in terms of how actual payments systems should operate journal of economic literature classification numbers e4 e5

modeling of industrial energy consumption an introduction and context industrial energy accounts for roughly one third of total global energy consumption and is expected to continue to use a similar share in the foreseeable future however this is one of the hardest end uses to analyze model and forecast the reasons for modeling industrial energy consumption are as varied as the ways in which energy is used in production processes this has led to the application of a broad set of emperical tools from several different disciplines in this article we provide an introduction and context for a compendium or survey of the methods used in this area this special issue of energy economics is designed to provide both newcomers and accomplished researchers with an overview of the current state of development in the are of industrial energy modeling

demandable debts as a means of payment banknotes versus checks we examine whether transactable forms of privately issued demandable debt are better used as banknotes or checks the distinction between the two is that a check must be redeemed by the issuing bank with each use whereas a banknote can circulate we find that the answer to the question depends on the cost of early redemption if this cost is small banknotes will not circulate so the question is moot if this cost is large incentive problems may prevent the circulation of banknotes for intermediate values of the early redemption cost banknotes will be preferred over checks

private and public circulating liabilities abstract legal and technological changes have made private banknote issue or its electronic equivalent possible we construct a model where private liabilities circulate either by themselves or alongside outside money we provide results on existence and multiplicity of equilibria and characterize dynamics near steady states our results support friedman in that circulating private liabilities are associated with endogenous volatility but implementing friedman s advice the government should ban private currency substitutes causes significant inefficiency the proposal of hayek that the government should leave currency creation to the market also is often constrained suboptimal both public and private circulating liabilities are required for optimality journal of economic literature classification numbers e3 e4 e5

financial development growth and the distribution of income a paradigm is presented in which both the extent of financial intermediation and the rate of economic growth are endogenously determined financial intermediation promotes growth because it allows a higher rate of return to be earned on capital and growth in turn provides the means to implement costly financial structures thus financial intermediation and economic growth are inextricably linked in accord with the goldsmith mckinnon shaw view on economic development the model also generates a development cycle reminiscent of the kuznet hypothesis in particular in the transition from a primitive slow growing economy to a developed fast growing one a nation passes through a stage in which the distribution of wealth across the rich and poor widens

decomposing energy demand across briic countries energy plays an important role within the production technology of fast emerging economies such that firms reaction to changes in energy prices provides useful information on factor productivity and factor intensity as well as the likely outcome of energy policy initiatives among other things drawing on duality theory this paper decomposes changes in energy demand into substitution and output effects using annual sector level production data for brazil russia india indonesia and china briic for the period 1995 2009 unlike previous studies this study analyzed the economic properties of the underlying production technology results indicate that changes in energy demand are strongly dominated by substitution effects more importantly an intriguing finding that emerges from our analysis is the role of economies of scale and factor accumulation as opposed to technical progress in giving rise to the growth performance of sampled economies

measuring the energy input substitution and output effects of energy price changes and the implications for the environment abstract previous studies of decomposition of factor inputs have limited their analysis on the estimation of substitution and output effects however this paper develops a two step approach to estimate the substitution and output effects of changes in energy demand resulting from changes in prices and further examines the implications of these effects on co2 emissions using european industrial dataset over the period 1995 2007 in our empirical estimations instead of relying only on isur model like previous studies we introduced a multilevel model which is a more befitting model to our data our analysis covers industry as a whole and for different sector types the primary results emerged from our analysis suggest a strong evidence using the multilevel model generally our results show that production inputs are substitutable we find the substitution and output effects to be negatively related to co2 emissions however the substitution effects dominate from policy perspectives our results suggest that output adjustments may not play a significant role in reducing emissions we find the overall effects of changes in energy demand to be moderate then we argue that increment in energy taxes should be complemented by cleaner factor substitution and sustainable growth to achieve a desirable carbon reduction

financial market participation financial intermediation and monetary policy abstract it is not uncommon for the friedman rule to be optimal in neoclassical models with money notably previous studies also find that financial intermediation is not welfare improving when money is costless to hold this paper departs from previous studies by highlighting the importance of participation costs in financial markets for the participation in financial intermediation and monetary policy as in previous work the friedman rule is optimal however i demonstrate that the welfare gains from disinflation are much higher when savings are intermediated if direct participation costs in financial markets are significant consequently financial intermediation can still be optimal at the friedman rule

costly monitoring loan contracts and equilibrium credit rationing this paper develops a model with asymmetrically informed agents and costly monitoring of loan contracts where an equilibrium can exhibit credit rationing borrowers are identical ex ante but some receive loans and others do not in contrast to existing credit rationing theories rationing does not occur here due to inflexible prices adverse selection or moral hazard optimizing behaviour produces a standard debt contract in equilibrium the aggregate quantity of loans and equilibrium interest rates respond differently depending on whether there is rationing in equilibrium

anticipated inflation and the capital stock in a cash in advance economy abstract an economy is constructed in which the steady state capital stock is inversely related to the rate of inflation as a result that is directly opposite the usual conclusion

underlying trends and seasonality in uk energy demand a sectoral analysis this paper demonstrates the importance for energy demand modelling of allowing for trends and seasonal effects that are stochastic in form inherent underlying trends may be non linear and reflect not only technical progress which usually produces greater energy efficiency but also other factors such as changes in consumer tastes and the economic structure that may be working in the opposite direction using quarterly unadjusted data for various sectors in the uk it is shown that unless energy demand models are formulated so as to allow for stochastic trends and seasonals estimates of price and income elasticities could be seriously biased

energy costs in germany and europe an assessment based on a total real unit energy cost accounting framework abstract affordable energy is one of the objectives of the eu s energy policy this goal has been challenged by many factors influencing energy prices and costs such as developments in global energy markets the eu ets and the promotion of renewables analysing energy costs prices times quantity instead of prices has the advantage of accounting for quantity adjustments however it does not allow for monitoring the burden that energy costs pose on firms for this purpose both the european commission and the energy expert commission of the german government recommend using real unit energy costs defined as energy costs as a fraction of value added we develop an input output based real unit energy cost accounting framework and study the trends in germany and the eu between 1995 and 2011 we find that many of the discovered developments are not adequately represented in the political debate especially with regard to indirect costs via energy embodied in intermediate inputs which are more difficult to assess indirect energy costs are on the rise are larger than direct costs in many industries are increasingly imported and amplify the asymmetric impacts of legal exceptions available to energy intensive industries

industrial electricity demand for turkey a structural time series analysis abstract this research investigates the relationship between turkish industrial electricity consumption industrial value added and electricity prices in order to forecast future turkish industrial electricity demand to achieve this an industrial electricity demand function for turkey is estimated by applying the structural time series technique to annual data over the period 1960 to 2008 in addition to identifying the size and significance of the price and industrial value added output elasticities this technique also uncovers the electricity underlying energy demand trend uedt for the turkish industrial sector and is as far as is known the first attempt to do this the results suggest that output and real electricity prices and a uedt all have an important role to play in driving turkish industrial electricity demand consequently they should all be incorporated when modelling turkish industrial electricity demand and the estimated uedt should arguably be considered in future energy policy decisions concerning the turkish electricity industry the output and price elasticities are estimated to be 0 15 and 0 16 respectively with an increasing but at a decreasing rate uedt and based on the estimated equation and different forecast assumptions it is predicted that turkish industrial electricity demand will be somewhere between 97 and 148 twh by 2020

optimality of the friedman rule in economies with distorting taxes abstract we find conditions for the friedman rule to be optimal in three standard monetary models our main contribution is to shed light on two issues in the literature first the conventional view maintains that when money is a final good its services should be taxed moreover if money demand is interest inelastic its services should be taxed heavily we show that this view is incorrect second there is an ongoing controversy about whether the optimality of the friedman rule is connected to the intermediate goods result from public finance we resolve this controversy by showing a deep connection between these results

financial consumption and the cost of finance measuring financial efficiency in europe 1950 2007 this paper proposes to assess financial intermediation efficiency in germany france the uk and europe more broadly over the past 60 years i rely on philippon s 2012 methodology which calculates the unit cost of financial intermediation through the ratio of financial consumption measured by financial income to financial output approximated by the sum of outstanding assets intermediated the contribution of this paper is threefold first because financial industry va ignores banks capital income capital gains dividends and interest on securities it is an imperfect measure of the consumption of financial intermediation so long as capital income generates wages and profits to financial intermediaries it is akin to an implicit consumption of financial services using banking income instead of banking va to measure the consumption of banking services i show that the gdp share of finance has increased continuously in germany france the uk and europe as a whole second the unit cost of financial intermediation increased over the past 40 years except in france where overall it stagnated in addition the european unit cost matches the us unit cost calculated by philippon 2012 finally because financial intermediaries deal with nominal stocks and ows and because the unit cost increases during periods of monetary troubles i focus here on nominal rates of interest to explain the evolution of unit cost i show that a rise in nominal rates of interest increases the spread of bank interest so that 1970s and 1980s high unit costs are statistically explained by increases in short term interest rates on the other hand post 1990s high unit cost seems to coincide with the development of new market based activities

capital energy substitution evidence from a panel of irish manufacturing firms abstract we use a translog cost function to model production in the irish manufacturing sector over the period from 1991 to 2009 we estimate both own and cross price elasticities and morishima elasticities of substitution between capital labour materials and energy we find that capital and energy are substitutes in the production process across all firms we find that a 1 rise in the price of energy is associated with an increase of 0 04 in the demand for capital the morishima elasticities which reflect the technological substitution potential indicate that a 1 increase in the price of energy causes the capital energy input ratio to increase by 1 5 the demand for capital in energy intensive firms is more responsive to increases in energy prices while it is less responsive in foreign owned firms we also observe a sharp decline in firms responsiveness in the first half of the sample period

the role of countercyclical monetary policy when firms set nominal prices in advance optimal monetary policy insulates aggregate output against shocks to demand it can do so however by following the constant money growth rule advocated by milton friedman it need not respond to the shocks in an actively countercyclical way in addition to the extent that output fluctuations are driven by shocks to supply money growth should be procyclical

the costs of losing monetary independence the case of mexico this paper develops a two country monetary model calibrated to data from the united states and mexico to address the question of whether dollarization is welfare improving for the two countries our findings suggest that dollarization is not necessarily pareto superior to monetary independence for mexico there are two persuasive arguments that are often put foleth in support of the idea that many countries would benefit from the adoption of the u s dollar as their national cultency one is the standard argument often made in favor of a common currency that it promotes economic and financial integration and reduces tleansaction costs the other argument is that dollarization would solve the credibility and commitment problem and impose monetary discipline the idea is that many countries particularly in latin america have long histories of high inflation and a record of breaking promises to pursue monetary policies that lead to low inflation taking monetary policy out of the hands of domestic central banks is one way to addleess this issue thus one of the conjectured benefits of adopting the u s dollar hinges on the prospect that this would eliminate an inflationary bias among the participating countries these benefits have to be balanced against the costs associated with the loss of monetary independence that eithele dollarization or a cultency area necessarily implies this loss of monetary independence means that the country can no longer use the instruments of monetary policy to adjust to internal or external shocks these considerations suggest two main questions that should be addressed in thinking about the proposal to adopt the u s dollar in mexico first is the higher inflation rate in mexico necessarily the result of the lack of monetaley discipline ole it can be justified by some principle of optimality in the conduct of monetary policy second is the welfare loss from not being able to use monetary policy to react optimally to shocks quantitatively important

the energy demand in the british and german industrial sectors heterogeneity and common factors abstract this paper estimates energy demands for the german and british industrial sectors over the 1978 2004 and the 1991 2004 samples from time series models we can conclude that there is a considerable variation in the value of the coefficients across sectors even though energy demands with sensible parameters can rarely be estimated when using a panel approach the ability of some estimators to allow for diversity across subsectors was an important factor in explaining the estimates for price elasticity on the other hand correlation across panel members or common factors did not markedly influence our results with regard to the estimated parameters our preferred choice for elasticity of economic activity and price in the longer sample is 0 52 and 0 64 similar values are found in the case of the shorter samples bearing in mind the high price elasticity energy taxes can be considered an effective strategy for reducing energy consumption

asymmetric substitutability between energy and capital evidence from the manufacturing sectors in 10 oecd countries abstract this paper investigates the substitutability between energy and capital in the manufacturing sectors of ten oecd countries since 1980 by applying a cost function approach that has been widely used to analyze industrial energy demand first we attempt to determine the source of the disagreement in the literature on the substitutability between energy and capital and reach a conclusion regarding the substitutability between energy and capital dividing energy and capital into sub inputs we analyze their substitutability the empirical results indicate that fuel tends to complement capital in most countries whereas electricity and capital are substitutes thus this study confirms that heterogeneity in energy sources is a primary component of the systematic variation in the substitutability between energy and capital second we examine asymmetric substitutability between energy and capital by estimating the morishima elasticity of substitution the estimates of the morishima elasticity of substitution demonstrate that the substitution of energy for capital has dominated the substitution of capital for energy this asymmetric substitutability is natural from the producer perspective because capital costs are much greater than energy costs in most countries these results imply that the adoption of energy saving technologies has not been induced in response to increased energy prices

market opportunities genetic endowments and intrafamily resource distribution child survival in rural india the authors examine how intrafamily resource allocations respond to changes in economic conditions and to genetic differences in children by estimating the determinants of variations in the sex specific survival differentials of rural indian children based on standard census and household survey data they explore in particular the hypothesis that such differences are related to the relative returns to survival with households selectively allocating resources to children in response to variation in sex differences in their expected earnings opportunities as adults data are from the 1961 census and a 1971 household survey excerpt

electricity demand elasticities and temperature evidence from panel smooth transition regression with instrumental variable approach abstract this study applies a non linear model i e the recently developed panel smooth transition regression pstr model and takes into account the potential endogeneity biases to investigate the demand function of electricity for 24 oecd countries from the period 1978 2004 our empirical results demonstrate that there is a strongly non linear link among electricity consumption real income electricity price and temperature a result that is new to the literature as real income rises electricity consumption rapidly increases first and after the level of real income exceeds approximately us 2500 its increasing rate turns slow down an increase in electricity price has a negative or no influence on electricity consumption evidence of a u shaped relationship between electricity consumption and temperature is supported and the threshold value of temperature is approximately 53 f which is endogenously determined furthermore the estimated elasticities of time dynamic indicate that electricity demand is income inelastic price inelastic and temperature inelastic as time goes on the absolute elasticities of electricity demand gradually decrease with respect to real gdp and electricity price whereas they gradually increase with respect to temperature suggesting that the impact of temperature on electricity demand is becoming more important in recent years

sub optimality of the friedman rule in townsend s turnpike and stochastic relocation models of money do finite lives and initial dates matter abstract the friedman rule a widely studied prescription for monetary policy is optimal in townsend s turnpike model of money it is not so in the overlapping generations version of his stochastic relocation model of money we investigate these monetary models in the light of this disparity to this end we create a modified version of the turnpike model that generates the same stationary monetary equilibria as does the two period overlapping generations model with random relocation we exploit this equivalence to explain the aforementioned disparity we also discuss the importance of whether or not the economy has an initial date

two illustrations of the quantity theory of money of 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 the illustrations were obtained by comparing moving averages of the three variables in question using quarterly u s time series for the period 1953 77 readers may find the results of interest as additional confirmation of the quantity theory as an example of one way in which the quantity theoretic relationships can be uncovered via atheoretical methods from time series which are subject to a variety of other forces or as a measure of the extent to which the inflation and interest rate experience of the postwar period can be understood in terms of purely classical monetary forces the theoretical background of the study is reviewed very briefly as it is familiar material in the next section the data processing methods are described and rationalized in section ii the illustrations
