was the emergence of the international gold standard expected evidence from indian government securities abstract the emergence of the gold standard has for a long time been viewed as inevitable we analyze agents expectations using the spread between gold and silver bonds issued by the indian government we find that bimetallism was credible until france surprised markets by suspending domestic operation of bimetallism triggering a run away from silver thereafter markets began demanding a premium to hold silver bonds indicating their belief that silver would depreciate in the future as more countries moved on gold

wealth distribution in life cycle economies abstract this paper compares the age wealth distribution produced in life cycle economies to the corresponding distribution in the us economy the idea is to calibrate the model economies to match features of the us earnings distribution and then examine the wealth distribution implications of the model economies the findings are that the calibrated model economies with earnings and lifetime uncertainty can replicate measures of both aggregate wealth and transfer wealth in the us furthermore the model economies produce the us wealth gini and a significant fraction of the wealth inequality within age groups however the model economies produce less than half the fraction of wealth held by the top 1 percent of us households

housing market heterogeneity in a monetary union this paper studies the implications of cross country housing market heterogeneity in a monetary union for both shock transmission and welfare i develop a two country new keynesian general equilibrium model with housing and collateral constraints to explore this issue the conventional wisdom is that welfare would be higher in a monetary union if mortgage markets were homogeneous this paper shows instead that welfare is higher only when homogenization does not result in higher aggregate volatility because of financial accelerator effects or does not redistribute too much wealth from borrowers to savers

time series model forecasts and structural breaks evidence from spanish pre emu interest rates analysis of the future behaviour of economic variables can be biased if structural breaks are not considered when these structural breaks are present the in sample fit of a model gives us a poor guide to ex ante forecast performance this problem is true for both univariate and multivariate analysis and can be extremely important when co integration relationships are analysed the main goal of this article is to analyse the impact of structural breaks on forecast accuracy evaluation we focus on forecasting several interest rates from the spanish interbank money market in order to carry out the analysis we perform two forecasting exercises a without structural breaks and b when structural breaks are explicitly considered we use new sequential methods in order to estimate change points in an endogenous way this method allows us to detect structural breaks in all four rates in may 1993 however the effects of these breaks are not very strong since we found scarce gains in forecasting accuracy w

arbitrage bounds in markets with noisy prices and the puzzle of negative option prices implicit in bonds abstract the term structure of interest rates has occupied economists for many years this is testimony to the importance of the term structure or equivalently valuation operator and to the difficulty of obtaining reliable estimates of it until recently it was not possible to reconcile the theoretical existence of a multiplicity of valuation operators in an incomplete bond market and the empirical nonexistence of even a single one mackay and prisman estimating valuation operators in incomplete market with noises can noise complete the market working paper 1996 tackle this problem in this paper an amendment to and a generalization of their methodology is presented the amendment preserves the linearity of valuation operators and allows use of efficient linear programming techniques further it facilitates an admissible consideration of the puzzle of negative option prices embedded in bonds the empirical results presented in this paper were obtained using data on extendable government of canada bonds the results indicate that although the gap between the lowest and the highest prices assigned to a cash flow by different valuation operators is significant it is not sufficient to resolve the above mentioned puzzle

secular changes in wealth inequality and inheritance data suggest that the distribution of wealth among households in the usa and uk has become more equal over the last century though at least for the usa the pattern may have reversed recently this paper shows that a model in which all households save for life cycle reasons and some for dynastic purposes as well offers a possible or partial explanation the model predicts rising cross sectional equality of wealth when longevity increases there may also be implications about very recent changes expansion of social security programmes and government deficits can lead toward more wealth inequality slower growth may do the same

growth effects of flat rate taxes recent estimates of the potential growth effects of tax reform vary wildly ranging from zero to eight percentage points using an endogenous growth model we assess which model features and parameter values are important for determining the quantitative impact of tax reform we find that the critical parameters are factor shares depreciation rates the elasticity of intertemporal substitution and the elasticity of labor supply the elasticities of substitution in production on the other hand are relatively unimportant the quantitative estimates in several recent papers are compared with each other and with some of the evidence from u s experience we find that robert lucas s conclusion that tax reform would have little or no effect on the u s growth rate is theoretically robust and consistent with the evidence

the role of intergenerational transfers and life cycle saving in the accumulation of wealth he purpose of this paper is to review what economists know at present about the following question how large a portion of the existing wealth is the result of a bequest motive that is of accumulation for the specific purpose of leaving bequests i will also endeavor to clarify why an answer to this question is of interest in the early keynesian period when the study of national saving first attracted wide interest relatively little attention was paid to what led people to save though it was generally understood that the main systematic reason was to leave bequests j m keynes in the famous chapter 9 of the general theory of employment interest and money 1936 had listed seven distinct motives for saving besides the leaving of bequests but five of these which include to increase one s future income or to insure one s independence and power implied that all or nearly all the accumulation would finally wind up as bequeathed wealth this in turn meant that most private wealth originated through bequests that is it either had been received through bequests or was destined to be bequeathed and indeed how else could society accumulate wealth however keynes 1936 p 107 also mentioned two further motives precaution that is to build up a reserve against unforeseen contingencies and foresight that is to provide for an anticipated future relation between the income and the needs of the individual or his family different from that which exists in the present as for example in relation to old age family education or the maintenance of dependents these motives in contrast to most of the previous ones have the

are negative option prices possible the callable u s treasury bond puzzle market prices for callable treasury bonds often imply negative values for the implicit call option the author considers a variety of possible explanations for these negative values including the treasury s track record in calling bonds optimally tax related effects tax timing options and bond liquidity none of these factors accounts for the negative values although the costs of short selling may explain why these apparent arbitrage opportunities persist over time why these implicit call values become negative in the first place remains a puzzle copyright 1992 by university of chicago press

a note on market efficiency institutional practice and economic constraints in the experience of the canadian bond market abstract for many years government of canada bonds with high coupons traded at much higher yields than those with lower coupons this apparent market inefficiency virtually disappeared over a short period of time during 1993 several events occurred in 1993 which relate to the narrowing of the spread this paper shows the earlier yield spread to be consistent with restrictions on the trading of strip bonds it also finds it difficult to defend the hypothesis that the higher yield spread represented unexploited profit opportunities

random earnings differences lifetime liquidity constraints and altruistic intergenerational transfers abstract this paper develops a model of private savings behavior in which households care about their descendants cannot have negative net worth and have lifetime earnings depending on random draws from an exogenous distribution of abilities the elements interact very lucky parents are likely to leave large estates constrained children are unusually likely to receive intergenerational transfers the paper proves the existence of a stationary cross sectional distribution of wealth endogenously determines where liquidity constraints will bind and shows that the long term interest rate must be such that ricardian neutrality fails its last section generates several illustrative numerical simulations

labor supply in the past present and future a balanced growth perspective the absence of a trend in hours worked in the postwar united states is an exception across countries and historically hours fall steadily by a little below 0 5 per year are steadily falling hou

social security and individual welfare precautionary saving borrowing constraints and the payroll tax this paper examines the impact of social security on national saving and individual welfare in the presence of realistic capital market imperfections market failure in the private provision of annuities and restrictions on borrowing against anticipated future wages the introduction of social security increases lifetime welfare and reduces national saving if borrowing restrictions are absent however the increase in individual welfare is reduced and in some cases eliminated when borrowing constraints are taken into consideration the substantial difference suggests the importance of reexamining the proportional payroll tax finance of social security copyright 1987 by american economic association

negative option values are possible the impact of treasury bond futures on the cash u s treasury market abstract this paper uses a unique financial instrument in the u s treasury market to study the price behavior of the put option embedded in the november 2009 14 callable u s treasury bond we find that beginning in august 1993 the estimated option value was persistently negative on nearly every day for the ensuing eight months we show that the anomalous pricing behavior arose because the underlying callable bond became the cheapest to deliver issue against u s treasury bond futures contracts hence this paper provides direct evidence that derivative assets can significantly distort pricing in the primary asset market

individual and aggregate labor supply in heterogeneous agent economies with intensive and extensive margins we develop a heterogeneous agent general equilibrium model that incorporates both intensive and extensive margins of labor supply a nonconvexity in the mapping between time devoted to work and labor services distinguishes between extensive and intensive margins we consider calibrated versions of this model that dier in the value of a key preference parameter for labor supply and the extent of heterogeneity the model is able to capture the salient features of the empirical distribution of hours worked including how individuals transit within this distribution we then study how the various specications inuence labor supply responses to aggregate technology shocks we nd that abstracting from intensive margin adjustment has large eects on the volatility of aggregate hours even if intensive margin uctuates relatively little

pareto and piketty the macroeconomics of top income and wealth inequality abstract since the early 2000s research by thomas piketty emmanuel saez and their coauthors has revolutionized our understanding of income and wealth inequality in this paper i highlight some of the key empirical facts from this research and comment on how they relate to macroeconomics and to economic theory more generally one of the key links between data and theory is the pareto distribution the paper describes simple mechanisms that give rise to pareto distributions for income and wealth and considers the economic forces that influence top inequality over time and across countries for example it is in this context that the role of the famous r g expression is best understood

intergenerational transfers and savings in recent years the role of intergenerational transfers in the process of wealth accumulation has been the subject of substantial empirical and theoretical analysis the key question stimulating this research is what is the main explanation for savings is it primarily accumulation for retirement as claimed by albert ando richard brumberg and franco modigliani in their celebrated life cycle model of savings is it primarily intentional accumulation for intergenerational transfers or is it primarily precautionary savings much of which may be bequeathed because of imperfections in annuity markets this paper examines a range of findings on the importance of intergenerational transfers the strong conclusion that emerges from this evidence is that intergenerational transfers play a very important if not a key role in aggregate wealth accumulation while intergenerational transfers figure very large in savings the precise motivation for such transfers is unclear intergenerational altruism might appear the most likely candidate but at least sane stylized facts such as the equal allocation of bequests among children are strongly at adds with the altruism model other explanations involving imperfect insurance arrangements or payments for child services do not appear capable of explaining the substantial amounts of transfers actually observed sorting cut the relative contributions of different models to intergenerational transfers and the precise role of intergenerational transfers in the process of wealth accumulation remains an intriguing and exciting enterprise this abstract was borrowed from another version of this item

strategic trading behavior and price distortion in a manipulated market anatomy of a squeeze abstract this paper investigates an attempted delivery squeeze in a bond futures contract traded in london using cash and futures trades of dealers and customers we analyze their strategic trading behavior price distortion and learning in a market manipulation setting we argue that marked differences in settlement failure penalties in the cash and futures markets create conditions that favor squeezes we recommend that regulators require special flagging of forward term repurchase agreements on the key deliverables that span futures contract maturity dates and that exchanges mark to market their contract specifications more frequently or consider a cash settled contract on a basket of bonds

human capital risk and economic growth this paper develops a tractable incomplete markets model of economic growth in which households invest in risk free physical capital and risky human capital the paper shows that a reduction in uninsurable idiosyncratic labor income risk decreases physical capital investment but increases human capital investment growth and welfare a quantitative analysis based on a calibrated version of the model reveals that these effects are substantial and of the same order of magnitude as the effects of distortionary income taxation the analysis further suggests that government sponsored severance payments to displaced workers increase growth and welfare even if these payments have to be e nanced through distortionary income taxation

liquidity reconstitution and the value of u s treasury strips an apparent pricing anomaly exists in the market for u s treasury strips zerocoupon strips created from principal payments typically trade at significantly higher prices than otherwise identical zero coupon strips created from coupon payments in addition to documenting this phenomenon this study demonstrates that differences in liquidity and differences in reconstitution characteristics explain much of this price variation u s treasury strips are zero coupon bonds created from either the principal or individual coupons of u s treasury bonds if the maturity date and face value are identical the cash flows for a strip derived from a principal payment are identical to the cash flows for a strip derived from a coupon payment however the two instruments almost always trade at significantly different prices for a recent sample 5 31 91 the mean percentage difference in price is greater than 1 2 with some differences greater than 2 7 this is an apparent anomaly since securities with identical cash flows should trade at the same price although coupon strips and principal strips have identical cash flows at maturity closer inspection reveals two differences the two instruments have different degrees of liquidity and different reconstitution characteristics previous studies have documented the effect of liquidity on prices in other markets amihud and mendelson 1986 1989 find that common stocks with differences in liquidity have significantly different risk adjusted rates of return silber 1991 studies restricted stock offerings and documents substantial price discounts on these illiquid securities vis a vis identical stocks that trade in the open market 1 in a study of u s treasury bills and treasury bonds with remaining maturities of less than six months amihud and mendelson 1991 find that differences in liquidity contribute to differences in prices between matched pairs of bills and bonds of the same

the role of intergenerational transfers in aggregate capital accumulation this paper uses historical u s data to directly estimate the contribution of intergenerational transfers to aggregate capital accumulation the evidence presented indicates that intergenerational transfers account for the vast majority of aggregate u s capital formation only a negligible fraction of actual capital accumulation can be traced to life cycle or hump savings a major difference between this study and previous investigations of this issue is the use of more accurate longitudinal age earnings and age consumption profiles these profiles are simply too flat to generate substantial life cycle savings this paper suggests the importance of and need for substantially greater research and data collection on intergenerational transfers life cycle models of savings that emphasize savings for retirement as the dominant form of capital accumulation should give way to models that illuminate the determinants of intergenerational transfers

the measurement of saving investment and wealth there is probably no concept other than saving for which u s official agencies issue annual estimates that differ by more than a third as they have done for net household saving or for which reputable scholars claim that the correct measure is close to ten times the officially published one yet despite agreement among economists and policymakers on the importance of this measure huge inconsistencies persist contributors to this volume investigate ways to improve aggregate and sectoral saving and investment estimates and analyze microdata from recent household wealth surveys they provide analyses of national income and product account nipa and flow of funds measures and of saving and survey based wealth estimates conceptual and methodological questions are discussed regarding long term trends in the u s wealth inequality age wealth profiles pensions and wealth distribution and biases in inferences about life cycle changes in saving and wealth some new assessments are offered for investment in human and nonhuman capital the government contribution to national wealth nipa personal and corporate saving and banking imputation

the life cycle model of consumption and saving a central implication of life cycle models is that agents smooth consumption we review the empirical evidence on smoothing at frequencies from within the year up to across a lifetime we find that life cycle models particular those which incorporate realistic features of markets and goods have more empirical successes than failures we also show that some apparent deviations from theoretical predictions imply very small welfare losses for agents finally we emphasize that the coherence of life cycle models imposes an important discipline when incorporating new features into models

income risk macroeconomic and demographic change and economic inequality in japan abstract using an olg model with heterogeneous households we investigate the relationship among income risk macroeconomic and demographic changes and economic inequality between 1980 and 2000 in japan by decomposing the primary factors in earnings and consumption inequality into macroeconomic variables and the demographic variable we find that our model replicates the evolution of economic inequality in japan by performing counterfactual simulations we demonstrate that two factors changes in time varying macroeconomic factors and the unexpected decline in the total factor productivity growth rate played important roles in the increase in earnings and consumption inequality in the 1990s

a macroeconomic analysis of energy subsidies in a small open economy we construct a dynamic model of a small open economy to analyze the effects of large energy subsidies the model includes domestic energy production and consumption trade in energy at world market prices as well as private and public sector production the model is calibrated to egypt and used to study reforms such as reductions in energy subsidies with corresponding reductions in various tax instruments or increases in infrastructure investment we calculate the new steady states transition paths to the new steady state and the size of the associated welfare losses or gains our main results for a 15 cut in energy subsidies are 1 steady state gross domestic product drops in most of our experiments as less energy is used in production 2 steady state consumption rises in most of our experiments 3 welfare can rise by as much as 0 6 in consumption equivalent terms 4 the largest gains in terms of output and of welfare can be obtained when savings from energy subsidy cuts are used to fund additional infrastructure investment jel e21 e63 h55 j26 j45 to understand the effects of subsidies and taxes on an energy sector and on consumption in a given country requires establishing a complete picture of the market in which it operates and of the various policies past and present that have applied to it iea 2010c 11 1 introduction a report by the international energy agency iea 2010a in 2010 identified 37 countries that together account for 95 of global subsidized fossil fuel consumption and found that total fuel consumption subsidies were about 557 billion in 2008 a stark increase from 342 billion in 2007 countries with the highest subsidies for energy turn out to be smaller oil producing countries like iran 65 billion in subsidies in 2009 20 of gross domestic product gdp saudi arabia venezuela and egypt iea 2010b the underpricing of energy can lead to excess consumption of energy that together with the need to finance these subsidies can have adverse economic effects both intra and intertemporally energy subsidies may therefore have large adverse effects on capital accumulation economic growth and hence welfare especially for future generations the iea estimates that many countries forgo faster growth of up to 2 6 by subsidizing energy iea 2010c since 2008 many major oil subsidizing countries have started to bring their prices in line with world market prices among them china russia india and indonesia many of the concerns about the inefficiency of energy subsidies have focused on environmental aspects and green house gas ghg emissions in particular the iea 2010c estimates that a world wide reduction of fuel subsidies could decrease ghg emissions in the long run by around 10 there are relatively few studies of the short term and long term macroeconomic effects of reductions in energy subsidies these effects are complex and require an explicit dynamic modeling approach there are many interrelated effects 1 phasing out energy subsidies alters the price of energy relative to other consumption goods and hence not only the quantity demanded for energy but also the demand for other goods 2 the degree of complementarity substitutability between these consumption goods together with the expectations of the time path for the phase out influences savings behavior and thus capital accumulation of households 3 changing energy subsidies influences use of energy in production whether energy is a complement or a substitute to other factors of production influences total output and marginal products of all factors of production 4 changes in factor payments influence household income and thus consumption and savings behavior 5 phasing out energy subsidies allows for other changes in the government budget such as changes in tax rates or other government expenditures which in turn will influence firm and household behavior

uncertain lifetime consumption and dissaving in retirement this paper asks whether the continued accumulation or mild dissaving observed among the retired can be explained by uncertain lifetime in the absence of annuities after an initial period influenced by borrowing constraints under constant relative risk aversion uncertain lifetime depresses consumption by a proportion increasing with age if the elasticity of intertemporal substitution in consumption is small illustrative computations based on actual income and survival data show that plausible elasticities are sufficiently small to give this effect the reduction in consumption is large enough to explain much of the lack of decumulation by the elderly

the risk free rate in heterogeneous agent incomplete insurance economies abstract why has the average real risk free interest rate been less than one percent the question is motivated by the failure of a class of calibrated representative agent economies to explain the average return to equity and risk free debt i construct an economy where agents experience uninsurable idiosyncratic endowment shocks and smooth consumption by holding a risk free asset i calibrate the economy and characterize equilibria computationally with a borrowing constraint of one year s income the resulting risk free rate is more than one percent below the rate in the comparable representative agent economy

a reexamination of option values implicit in callable treasury bonds abstract longstaff 1992 and edleson fehr and mason 1993 examine option values implicit in callable treasury bonds and report a significant puzzle implied option values are frequently negative using an alternative approach we reexamine this issue and find that implied option values are generally positive and in contrast to previous studies instances of option values sufficiently negative to overcome the bid ask spread are rare we explain the findings in other studies by showing that the method used may lead to the appearance of a negative option value when the true value is positive
