transition to fully funded pension schemes a non orthodox criticism summary the paper examines the dominant views on the adoption of mandatory fully funded pension schemes ff as a partial or complete substitute for the unfunded payg three obstacles to the ff reform are envisaged to begin with the reform may fail to boost workers marginal propensity to save since workers may contract their voluntary saving to compensate the larger mandatory saving to ff schemes secondly if payg s payroll contributions are reduced and diverted to a ff scheme the larger private saving supply will be balanced by a lower government saving if the government is committed to honour the current pension payments thirdly keynes saving paradox reinforced by the capital theory critique initiated by sraffa suggests that the effect of the rise in the marginal propensity to save is not an increase in capital accumulation but rather a fall of income and employment

the demand for beer wine and spirits a survey of the literature the demand for alcohol literature is vast and much conflicting information about the nature of the demand for alcoholic beverages has been published this paper presents a survey of the literature and then uses the technique of meta regression analysis to establish insights into the nature of the demand for beer wine and spirits unlike previous meta studies of the demand for alcoholic beverages this study adjusts for the precision of each elasticity estimate the analysis presented suggests reported elasticity estimates will be influenced by such factors as estimation technique data frequency and time period under consideration with respect to time the findings suggest that the demand for alcoholic beverages has become less inelastic since the mid 1950s and that the income elasticity has been falling since the mid 1960s the analysis also found support for the idea that alcohol as a commodity group is a necessity and that consumers respond to price discounting with inventory behaviour rather than true substitution behaviour little support is found for the idea that the demand for alcoholic beverages varies fundamentally across most countries although wine may be an exception language en

indeterminate steady state equilibria in a one sector model abstract this note introduces an overlapping generations with altruism model based on the assumption that the rich are more patient than the poor all consumers are identical in their exogenous parameters the division of the population into the rich and the poor occurs endogenously it is proved that steady state equilibria are indeterminate

labor flexibility and innovation in new ventures the study investigates how labor flexibility affects innovation in new ventures more specifically drawing upon a sample of 143 greek ventures less than 8 years old it examines empirically the individual and interactive effects of functional and numerical flexibility on product innovation it also considers how these effects are moderated by the entrepreneur s political skill results suggest that functional flexibility has a positive direct effect on incremental innovation whereas numerical flexibility has a positive direct effect on radical innovation the interactions between numerical and functional flexibility affect both types of innovation the results also suggest that the labor flexibility innovation relationship is positively moderated by the entrepreneur s political skill these findings point toward aspects of knowledge related with flexible labor engagement and entrepreneurial relational capital that affect innovation

exchange rate bands with price inertia this problem by committing member states to taking suitable action to prevent cross parities from straying outside some given publicly announced range and williamson s proposal for target zones was explicitly aimed at preventing exchange rate misalignment among the principal industrial countries subsequently the louvre accord struck between members of the group of seven in i 987 involved unpublished commitments designed to constrain fluctuation between the u s dollar and the currencies of its major trading partners funabashi i988 given the obvious practical importance of understanding the implications of such policy commitments for the economy in general and the exchange rate in particular it is perhaps not surprising that the seminal work by krugman i 988 i989 on exchange rate determination within a band has aroused considerable interest under the assumption that the velocity of money follows a brownian motion process he obtains an explicit solution for the exchange rate as a function of the fundamental which shows that the presence of a commitment to intervene so as to defend the band exerts a stabilising influence on the exchange rate even before any such intervention takes place in their contribution to this emerging literature froot and obstfeld i989 note that krugman s minimalist stochastic specification can be derived from a monetary model of exchange rates where prices are perfectly flexible and full employment prevails where international interest differentials match expected exchange rate changes and the exchange rate preserves purchasing power parity cf mussa 1976 and they show that the behaviour of the rate inside a currency band can be obtained using results on regulated brownian motion processes cf harrison i985 using the same framework and techniques flood and garber i989 indicate how the rate will respond to noninfinitesimal intervention and svensson i 989 examines the effect of bandwidth on the stochastic behaviour of interest rates klein i989 considers the effects of uncertainty about the width of the band

the existence of a two class economy in a general cambridge model of growth and distribution the existence of a two class economy in the kaldor 1956 model of economic growth and income distribution has been investigated by a number of economists the most recent contributions include maneschi 1974 gupta 1977 miickl 1978 fazi and salvadori 1981 recently pasinetti 1983 has taken on this issue once again in an article in which the kaldor model is analysed as a special case of a more general model in which three different savings ratios are envisaged this model was also studied by chiang 1973 maneschi 1974 and moore 1974 however hitherto the analysis has been carried out assuming a linear relationship between savings and income in this paper we explore a general model in which no parti cular assumption is made about the capitalists and workers savings functions some novel results emerge a cambridge theory of income distribution is built without having to resort to oversimplified functional forms and the famous 1962 pasinetti equation whereby the economy s rate of profit is determined only by the natural rate of growth and the savings habits of capitalists can be reached independently of any assumption on savings formation provided that the rate of interest is equal to the rate of profit the paper also provides a graphic presentation of the analysis this clarifies the geometric argument behind the properties of the kaldor model and makes obvious once again that recent criticisms of this model are unfounded in the case of the threefold savings ratio model our algebraic and geometric analysis yields results which are not completely in line with those reached by pasinetti 1983 some remarks on these differences are made

illicit drug use among arrestees prices and policy abstract prior studies by relying on nationally representative surveys have overlooked the important fact that use of addictive substances is not uniformly distributed subgroups of hardcore users account for most of the drug consumption this study employs the arrestee drug abuse monitoring system to analyze the demand for cocaine and heroin by urban arrestees employing objective indicators of use based on urinalysis the data are repeated city cross sections and panel data methodology is employed to account for endogeneity cocaine and heroin prices have a negative effect on the probability of use even among this group of heavy users results indicate that subjective self reported measures of participation are likely to be under reported which may impart bias to estimates of the price elasticity the own price cocaine participation elasticity is about 0 15 and the own price heroin participation elasticity is about 0 10 for arrestees this contemporaneous elasticity understates the full effect and the long run price elasticity is about twice the magnitude the magnitude of the price response is substantially smaller relative to the estimates in the prior literature and calculations suggest that further enforcement and interdiction driven increases in drug prices may not be cost effective

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

ricardian equivalence long run leviathan abstract this paper presents a heterogenous overlapping generations with altruism model in which intergenerational discounting is stochastic the model nests three popular macroeconomics models those of ramsey economic journal 38 152 1928 543 559 diamond american economic review 55 1965 1126 1150 and a variant of the blanchard journal of political economy 93 2 1985 223 247 buiter the economic journal 98 391 1988 279 293 weil journal of public economics 38 2 1989 183 198 model it is shown that under a mild condition originally derived by weil journal of monetary economics 19 3 1987 377 391 the long run capital intensity is robust to practically every popular theoretical criticism of the standard ricardian model these criticisms include the imperfect inheritability of time preference parameters and hence finite horizons on the part of all households myopia in the form of overly discounting the future borrowing constraints distortionary labor taxation exchange strategic bequest motives common cultural constraints egalitarian bequests and primogeniture endogenous fertility and joy of giving while precautionary saving can theoretically violate long run neutrality the asymptotic capital intensity is still bounded below by preference parameters the overall conclusions are sharply at odds with those found in most articles dealing with the theoretical foundations of ricardian equivalence

prohibition and the market for illegal drugs over the past 25 years in the united states enforcement of drug prohibition has expanded dramatically over the same period however the trends in drug production and consumption have been essentially flat and the real purityadjusted prices of both cocaine and heroin have more than halved this combination of facts raises questions about the effectiveness of prohibition enforcement and it constitutes a puzzle that is interesting to explain in this paper the authors document these facts and explore possible explanations they do not claim to provide a complete answer but shed light on which explanations are likely to be important

the economic case against drug prohibition this paper discusses the costs and benefits of drug prohibition it offers a detailed outline of the economic consequences of drug prohibition and a systematic analysis of the relevant empirical evidence the bottom line is that a relatively free market in drugs is likely to be vastly superior to the current policy of prohibition

playing with the band dynamic effects of target zones in an open economy this paper applies techniques of regulated brownian motion to a model of a small open economy to investigate how bands on fundamental driving variables affect the realization of the nominal exchange rate the real exchange rate prices and output the author shows that these bands mitigate the relationship between exogenous fundamentals and endogenous variables through their effects on expectations he also considers the effects of changing the width of the band and finds greater stabilization of endogenous variables with more narrow bands on exogenous fundamentals copyright 1990 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

target zones and realignments recent contributions emphasize that the presence of exchange rate target zones has important effects on the within band behavior of exchange rates when agents are forward looking the authors find that the implications of available models are inconsistent with european exchange rate data and they suggest that the frequent realignments occurring in the period they consider may be responsible for this they construct a model in which the likelihood of a realignment in the near future increases as the exchange rate approaches the limits of its fluctuation band and show that its implications are broadly consistent with the evidence copyright 1992 by american economic association

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

monetary and real shocks and the optimal target zone abstract an exchange rate target zone is analysed in a model where the economy is disturbed by shocks to money demand and goods demand the stabilising properties of a target zone are compared to those of fixed and flexible exchange rate regimes it is found that a target zone offers a compromise between these two extremes it is also shown that when there are shocks to both money and goods demand a target zone is better than either a fixed rate or a floating rate in the sense that it minimises the variance of output and prices

the effect of drug prohibition on drug prices evidence from the markets for cocaine and heroin this paper examines the effect of drug prohibition on the black market prices of cocaine and heroin the paper examines the ratio of retail to farmgate price for cocaine heroin and several legal goods and it compares legal versus black market prices for cocaine and heroin the results suggest that cocaine and heroin are substantially more expensive than they would be in a legalized market but to a lesser degree than suggested in previous research

a reply to michl in his comments tom michl defends the proposal for a fully funded pension scheme based on a saving led classical growth model against my keynesian contention that a higher saving supply would be deflationary in both the short run and the long run michl adds a further argument that an increase in the saving rate associated with a lower interest rate may speed up the accumulation process i remark that the thesis that a lower interest rate has a positive influence on investment is empirically and theoretically controversial while the idea that an increase in investment requires a larger saving supply is open to further keynesian objections copyright 2006 oxford university press

comments on cesaratto s transition to fully funded pension schemes a non orthodox criticism cesaratto s critique of the neoclassical approach to pension reform is valuable but he has overextended his argument in applying it to proposals to use pre funding as a mechanism for achieving greater public ownership and for redistributing wealth progressively the fiscal surpluses needed to pre fund the public pension system could increase investment provided that they are offset by an appropriately stimulating monetary policy the post keynesian investment literature descending from kalecki s principle of increasing risk motivates on non neoclassical grounds the interest sensitivity of investment required to make this policy mix effective copyright 2006 oxford university press

intergenerational transfers and the accumulation of wealth h t ouseholds acquire wealth from two sources they save out of income they have earned and they receive transfers from other people the first method of wealth accumulation goes under the name of life cycle saving in which people save during their working lives and dissave after retirement the second involves either an inter vivos transfer that is a transfer between living people or a bequest a transfer that occurs at the death of the donor while inter vivos transfers and bequests will arise in dynastic models where preferences include a taste for the well being of one s descendents few empirical life cycle models reflect these concerns indeed a sharp debate has arisen over the ability of the simple life cycle model to explain observed wealth accumulation understanding the relative sizes of these sources of wealth accumulation affects a variety of issues for example the effects of government debt social insurance public transfer programs estate taxes and incentives for charitable giving depend to some extent on the magnitude and nature of private saving and transfers of wealth analyses of the inequality of wealth may depend on whether most of wealth is earned or received as transfers appropriate policies for encouraging private saving may look rather different depending on whether most saving is to be consumed later in life or passed along to the next generation finally evidence on transfer patterns relates to more fundamental

social security in a classical growth model this paper develops a growth model with overlapping generations of workers who save for life cycle reasons and ricardian capitalists who save from a bequest motive the population of workers accommodates growth so that the rate of capital accumulation is endogenous and determines the growth of employment two regimes are possible one in which workers saving dominates the long run and a second in which the long run equilibrium growth rate is determined completely by the capitalist saving function sometimes called the cambridge equation the second regime exhibits a version of the pasinetti paradox changes in workers saving affect the level but not the growth rate of capital in the long run applied to social security this result implies that an unfunded system relying on payroll taxes reduces workers lifetime wealth and saving creating level effects on the capital stock without affecting its long run growth rate these effects are mitigated by the presence of a reserve fund various levels of which are examined calibrating the model to realistic parameter values for the us facilitates an interpretation of the controversies over the percentage of the national wealth originating in life cycle saving and the effects of social security on saving the model is offered as an analytical framework for the review of current topics in fiscal policy in particular identifying the social security reserve fund as a potential vehicle for generating capital accumulation and effecting a progressive redistribution of wealth copyright 2004 oxford university press
