hedge fund performance 1990 2000 do the money machines really add value we investigate the claim that hedge funds offer investors a superior risk return tradeoff we do so using a continuous time version of dybvig s 1988a 1988b payoff distribution pricing model the evaluation model which does not require any assumptions with regard to the return distribution of the funds to be evaluated is applied to the monthly returns of 77 hedge funds and 13 hedge fund indices from may 1990 april 2000 the results show that as a stand alone investment hedge funds do not offer a superior risk return profile we find 12 indices and 72 individual funds to be inefficient with the average efficiency loss amounting to 2 76 per annum for indices and 6 42 for individual funds part of the inefficiency cost of individual funds can be diversified away funds of funds however are not the preferred vehicle for this as their performance appears to suffer badly from their double fee structure looking at hedge funds in a portfolio context results in a marked improvement in the evaluation outcomes seven of the 12 hedge fund indices and 58 of the 72 individual funds classified as inefficient on a stand alone basis are capable of producing an efficient payoff profile when mixed with the s p 500 the best results are obtained when 10 20 of the portfolio value is invested in hedge funds

on equilibrium asset price processes in this article we derive necessary and sufficient conditions that must be satisfied by equilibrium asset price processes in apure exchange economy we examine a world in which asset prices follow a diffusion process asset markets are dynamically complete all investors maximize their state independent expected utility of consumption at some future date and investors have nonrandom exogenous income we show that it is necessary and suffcient that the coefficients of an equilibrium diffusion price process satisfy a partial differential equation and a boundary condition we also examine how the dynamics of asset prices are related to the shape of the representative investor s utility function through the boundary condition for example in a constant volatility economy the expected instantaneous return of the market portfolio is mean reverting if and only if the relative risk aversion of the representative investor is decreasing in terminal wealth

the global and local dimensions of place making remaking shanghai as a world city shanghai the largest socialist industrial city in china is now experiencing dramatic restructuring under global and local forces this paper provides a preliminary account of remaking this city into a world city the case study suggests the tremendous and pervasive impact of globalisation on the city in transitional economies although it is still not comparable with a truly global city the growth of inward investment particularly its penetration into real estate development has exerted direct impacts on the urban structure it is argued that however that this global influence can only be realised through the coincidence of indigenous changes in the political economy system specifically the willingness of the central government to give more autonomy to local governments the new policy to set up a window for china s open policy the incentive for making money from selling the space the injection of public money into infrastructure and fierce promotional development strategies all contributed to the process of urban restructuring the effect of combined global and local changes has led to an extremely optimistic growth atmosphere and a building boom since the mid 1990s shanghai highlights the local as well as the global dimensions of urban change in the post socialist economies

evidence on substitutability of adult and child labour whether child labour displaces adult labour giving rise to unemployment is a matter of their substitutability in production using a flexible form production function fitted to data on egypt s economy we generate hicks elasticities of complementarity own and cross price elasticities as well as simulate employment effects on adult labour as a result of changing the fixed quantity of labour in compliance with the international call to end child labour adult males appear to be complementary with and adult females substitutes for child labour although the employment effects of banning child labour are inconclusive

local governments as industrial firms an organizational analysis of china s transitional economy despite widespread skepticism about government ownership in transitional economies china s rapid industrial growth has been led by public enterprises kornai s theory of soft budbet constraints born of the failure of earlier hungarian reforms fosters such skepticism but it assumes as fixed organizational characteristics that in fact vary widely across government jurisdictions local governments with smaller industrial bases have clearer financial incentives and constraints fewer nonfinancial interests in enterprises and a greater capacity to monitor them in china s vast public sector the fastest growth in output and productivity has occurred where government ownership rights are clearest and most easily enforced which enables officials to manage public industry as a diversified market oriented firm

farm productivity and rural poverty in india armed with new data we return to an old question from the pages of this journal to what extent do india s rural poor share in agricultural growth combining data from 24 household sample surveys spanning 35 years with other sources we estimate a model of the joint determination of consumption poverty measures agricultural wages and food prices we find that higher farm productivity brought both absolute and relative gains to poor rural households a large share of the gains was via wages and prices though these effects took time the benefits to the poor were not confined to those near the poverty line

decoding urban land governance state reconstruction in contemporary chinese cities in the rapidly growing literature on urban development in china many authors have emphasised the salient features of economic decentralisation and the increasingly significant role of the local state however such arguments neglect a counter trend in which the central state has deterritorialised and rehierarchised some key functions using the case of land governance this paper argues that facing the complication of changing urban conditions there is a resurgence of the state s regulatory power the decentralisation of economic governance is now counter balanced by the rise of state strategies to control the articulation of scales through which a more centrally consolidated power can be achieved the central government still serves as an important level of economic regulation in this sense new interpretations of commoditised urban transformation especially commoditised production of the built environment should be understood by underscoring the interplay between trends of decentralisation and terr

when are path dependent payoffs suboptimal abstract generalizing a result by cox and leland 2000 vanduffel et al 2009 this note shows that risk averse investors with fixed planning horizon prefer path independent payoffs in any financial market if the pricing kernel is a function of the underlying s price at the end of the planning horizon generally for every payoff which is not a function of the pricing kernel there is a more attractive alternative that depends solely on the pricing kernel at the end of the planning horizon

why has economic growth been more pro poor in some states of india than others abstract we use 20 household surveys for india s 15 major states spanning 1960 1994 to study how the sectoral composition of economic growth and initial conditions interact to influence how much growth reduced consumption poverty the elasticities of measured poverty to farm yields and development spending did not differ significantly across states but the elasticities of poverty to urban and rural non farm output varied appreciably and the differences were quantitatively important to the overall rate of poverty reduction states with higher elasticities did not experience higher rates of non farm growth the non farm growth process was more pro poor in states with initially higher literacy higher farm productivity higher rural living standards relative to urban areas lower landlessness and lower infant mortality

inefficient dynamic portfolio strategies or how to throw away a million dollars in the stock market a number of portfolio strategies followed by practitioners are dominated because they are incompletely diversified over time the payoff distribution pricing model is used to compute the cost of following undiversified strategies simple numerical examples illustrate the technique and computer generated examples provide realistic estimates of the cost of some typical policies using reasonable parameter values the cost can be substantial and should not be ignored by practitioners a section on generalizations shows how to extend the analysis to term structure models and other general models of returns this abstract was borrowed from another version of this item

recovery of preferences from observed wealth in a single realization von neumann morgenstern preferences over terminal consumption can be inferred from wealth on a single sample path when markets are complete and returns follow a known law in a neoclassical investment problem in either a discrete time i i d binomial model or a continuous time diffusion model with a gaussian state variable numerical results suggest that useful information about preferences can be obtained from even a single noisy sample of monthly observations of a portfolio over 5 years article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

on dynamic investment strategies abstract this paper presents a new approach for analyzing dynamic investment strategies previous studies have obtained explicit results by restricting utility functions to a few specific forms not surprisingly the resultant dynamic strategies have exhibited a very limited range of behavior in contrast we examine what might be called the inverse problem given any specific dynamic strategy can we characterize the results of following it through time more precisely can we determine whether it is self financing yields path independent returns and is consistent with optimal behavior for some expected utility maximizing investor we provide necessary and sufficient conditions for a dynamic strategy to satisfy each of these properties

federalism chinese style the political basis for economic success in china china s remarkable economic success rests on a foundation of political reform providing a considerable degree of credible commitment to markets this reform reflects a special type of institutionalized decentralization that the authors call federalism chinese style this form of decentralization has three consequences first it fosters competition not only in product markets but also among local governments for labor and foreign capital this competition in turn encourages local government experimentation and learning with new forms of enterprises regulation and economic relationships second it provides incentives for local governments to promote local economic prosperity finally it provides a significant amount of protection to local governments and their enterprises from political intrusion by the central government

china s changing urban governance in the transition towards a more market oriented economy china s changing urban development processes and urban landscapes in the transition towards a more market oriented economy have received extensive research attention in recent years relatively the governing of chinese cities is still underresearched this article aims to analyse the forces released both inside and outside the formal socialist state system and the impacts on phenomenal restructuring of urban governance especially at local levels marketisation has created new elements beyond the reach of state work units that represent the state s hierarchical control the pillars of the socialist governing structure the party state the work units system and household registration are shaken by these forces the changes in the organisation of people capital production materials infrastructure and space fundamentally demand new urban governance territorial organisations such as the municipality urban districts street office and residents committees are reinvented and consolidated to restore a governable society the devolution towards the base level and the reinvention of local communities reflect the state s attempt to reconsolidate its power to create a governable society as well as to cope with practical pressures such as the provision of social assistance to poor and aged residents re employment of laid off workers and the management of floating immigrants the combination of new market elements and decentralised state apparatus has given rise to the entrepreneurial endeavour of china s governance this research highlights the micro foundation of the new urban governance in addition to the globalisation capital mobility city competitiveness thesis

urban spatial development in the land policy reform era evidence from beijing this paper examines the characteristics of urban spatial development in beijing and identifies the extent to which these characteristics can be attributed to the emerging land market in beijing as

capital growth with security abstract this paper discusses the allocation of capital over time with several risky assets the capital growth log utility approach is used with conditions requiring that specific goals are achieved with high probability the stochastic optimization model uses a disjunctive form for the probabilistic constraints which identifies an outer problem of choosing an optimal set of scenarios and an inner conditional problem of finding the optimal investment decisions for a given scenarios set the multiperiod inner problem is composed of a sequence of conditional one period problems the theory is illustrated for the dynamic allocation of wealth in stocks bonds and cash equivalents

federalism as a commitment to reserving market incentives the authors advance a new perspective in the study of federalism their approach views federalism as a governance solution of the state to credibly preserving market incentives market incentives are preserved if the state is credibly prevented from compromising on future economic success and from bailing out future failures the salient features of federalism decentralization of information and authority and interjurisdictional competition help provide credible commitment or these purposes in addition the authors suggest that some federalism are self sustaining

is india s economic growth leaving the poor behind there has been much debate about how much india s poor have shared in the economic growth unleashed by economic reforms in the 1990s the authors argue that india has probably maintained its 1980s rate of poverty reduction in the 1990s however there is considerable diversity in performance across states this holds some important clues for understanding why economic growth has not done more for india s poor india s economic growth in the 1990s has not been occurring in the states where it would have the most impact on poverty nationally if not for the sectoral and geographic imbalance of growth the national rate of growth would have generated a rate of poverty reduction that was double india s historical trend rate states with relatively low levels of initial rural development and human capital development were not well suited to reduce poverty in response to economic growth the study s results are consistent with the view that achieving higher aggregate economic growth is only one element of an effective strategy for poverty reduction in india the sectoral and geographic composition of growth is also important as is the need to redress existing inequalities in human resource development and between rural and urban areas
