the dynamic cost and persistence of asset inequality in an agrarian economy abstract a growing literature suggests that asset inequality can be economically costly in the presence of agency costs that constrain labor and capital markets unclear in this literature is whether asset markets and optimal individual accumulation of self finance capacity suffice to eliminate costly inequality over time this paper uses numerical dynamic programming methods to explore this question with a model of an initially inegalitarian agrarian economy while an egalitarian asset distribution emerges over time the process involves sufficiently great productivity losses along the way that a redistributive policy could improve on the market s performance by both equity and efficiency criteria

china s collectivisation puzzle a new resolution according to total factor productivity trends in chinese agriculture china achieved productivity gains both when collectivising 1954 58 and when decollectivising 1979 84 its agriculture if the productivity gains from decollectivisation were due mainly to eliminating the incentive problems of collective farms how the initial collectivisation could also have been associated with gains in productivity presents a major historical puzzle we suggest as an answer the possibility that agricultural production in china was widely organised on a household basis until 1958 despite the collectivisation of property rights and that the formation of the agricultural producers co operatives reduced the inefficiencies in factor allocation that existed following china s land reform

agrarian structure and agricultural practice typology and application to western sudan a typology of models that explain patterns of variation in farm endowments and farm practices and yields shows that insecurity in renting land financing constraints and the absence of insurance generate patterns of factor use quite different from the famous inverse relationship caused by labor supervision problems one might expect to observe positive relationships between wealth and yields village level data from western sudan confirm that such positive relationships are not a theoretical curiosity wealthy farmers have higher levels of output per hectare because they use more labor per hectare insurance and financing constraints appear to be the crucial market failures

market timing and mutual fund performance an empirical investigation the evaluation of investment performance is of importance for allocating investment funds efficiently and setting appropriate management fees because actively managed mutual funds are an important form of investment in the united states a valid question is whether the active management has achieved a sufficient increase in returns to offset the associated costs of information and transactions as well as the management fees charged as a corollary the ability to earn superior returns based on superior forecasting ability would be a violation of the efficient markets hypothesis and would have far reaching implications for the theory of finance 2 henriksson and merton 1981 present statistical techniques for testing forecasting ability with a particular emphasis on the market timing ability of investment managers the tests are derived from the basic model of market timing developed by merton 1981 where the forecaster predicts when stocks will outperform riskless securities and when riskless securities will outperform stocks but does not predict the magnitude of the relative returns the evaluation of the performance of investment managers is a topic of considerable interest to practitioners and academics alike using both the parametric and nonparametric tests for the evaluation of forecasting ability presented by henriksson and merton the market timing ability of 116 open end mutual funds is evaluated for the period 1968 80 the empirical results do not support the hypothesis that mutual fund managers are able to follow an investment strategy that successfully times the return on the market portfolio

access to capital and agrarian production organisation there are two problems both universal that entrepreneurs in any economy must contend with firstly an agent generally has access only to a limited amount of working capital secondly workers hired by an agent are subject to moral hazard and this necessitates their supervision this paper models for an agrarian economy the constraints imposed on entrepreneurs activities by these two problems and endogenously determines the various organisational forms of production as well as the allocation of resources that will obtain with a simple model we endeavour to explain a diverse set of empirical observations pertaining to the less developed countries in terms of the general processes that determine the distribution of income among the various agents and the hierarchical relationships that develop among them agricultural production typically involves a period of several months between the time the inputs are purchased and the time the output is marketed access to working capital and hence to the credit market thus plays an important role in a farmer s production decisions the distribution of access to credit in turn tends to be an important determinant of income distribution in poor agrarian economies credit is invariably rationed according to the ability to offer collateral the amount of working capital a farmer can mobilise therefore depends on the amount of land he owns which is often a good proxy for his overall wealth and thus his ability to offer collateral further since hired hands have a propensity to shirk they need to be supervised and therefore the

contractual structure and wealth accumulation can historical wealth distributions affect long run output and inequality despite rational saving convex technology and no externalities we consider a model of equilibrium short period financial contracts where poor agents face credit constraints owing to moral hazard and limited liability if agents have no bargaining power poor agents have no incentive to save poverty traps emerge and agents are polarized into two classes with no interclass mobility if instead agents have all the bargaining power strong saving incentives are generated the wealth of poor and rich agents alike drift upward indefinitely and history does not matter eventually d31 d91 i32 o17 q15

agricultural transformation in africa assessing the evidence in ethiopia summary despite significant efforts africa has struggled to imitate the rapid agricultural growth that took place in asia in the 1960s and 1970s as a rare but important exception ethiopia s agriculture sector recorded remarkable rapid growth during 2004 14 this paper explores this rapid change in the agriculture sector of this important country the second most populous in africa we review the evidence on agricultural growth and decompose the contributions of modern inputs to growth using an adjusted solow decomposition model we also highlight the key pathways ethiopia followed to achieve its agricultural growth we find that land and labor use expanded significantly and total factor productivity grew by about 2 3 per year over the study period moreover modern input use more than doubled explaining some of this growth the expansion in modern input use appears to have been driven by high government expenditures on the agriculture sector including agricultural extension but also by an improved road network higher rural education levels and favorable international and local price incentives

portfolio performance evaluation old issues and new insights this article presents a model that provides insights about various measures of portfolio performance the model explores several criticisms of these measures these include the problem of identifying an appropriate benchmark portfolio the possibility of overestimating risk because of market timing ability and the failure of informed investors to earn positive risk adjusted returns because of increasing risk aversion the article argues that these need not be serious impediments to performance evaluation

wealth weather risk and the composition and profitability of agricultural investments despite the growing evidence that farmers in low income environments are risk averse there has been little empirical evidence on the importance of risk in shaping the actual allocation of production resources among farmers differentiated by wealth the authors use panel data on investments in rural india to examine how the composition of productive and nonproductive asset holdings varies across farmers with different levels of total wealth and across farmers facing different degrees of weather risk income variability is a prominent feature of the experience of rural agents in low income countries the authors report evidence based on measures of rainfall variability that the agricultural investment portfolio behavior of farmers in such settings reflects risk aversion due evidently to limitations on consumption soothing mechanisms such as crop insurance or credit markets the authors results suggest that uninsured weather risk is a significant cause of lower efficiency and lower average incomes a one standard deviation decrease in weather risk measured by the standard deviation of the timing of the rainy season would raise average profits by up to 35 percent among farmers in the lowest wealth quartile moreover rainfall variability induces a more unequal distribution of average incomes for a given distribution of wealth wealthier farmers are willing to absorb significant risk without giving up profits to reduce production risk smaller farmers have to invest their limited wealth in ways that reduce their exposure to risk at the cost of lower profit rates the authors found that at high levels of rainfall variability differences in rates of profit per unit of agricultural assets were similar across classes of wealth but over the sample range of rainfall variability these rates of profit were always higher for the poorer farmers than for the wealthier ones suggesting that the disadvantages of small farmers in risk diffusion are more than offset by their labor cost advantage

participation in rural land rental markets in sub saharan africa who benefits and by how much evidence from malawi and zambia we use nationally representative household level panel survey data in two neighboring countries in southern africa zambia and malawi to characterize the current status of rural land rental market participation by smallholder farmers and their subsequent welfare impacts rural rental market participation is much higher in densely populated malawi than in lower density zambia reflecting the role of land scarcity in driving rental market development consistent with previous literature we find evidence that rental markets contribute to efficiency gains within the smallholder sector by facilitating the transfer of land from less able to more able producers on average in both countries furthermore we find that rental markets serve to re allocate land from relatively land rich to land poor households we examine the impacts of participation on a number of welfare outcomes and find evidence for generally positive returns to renting in land in both countries on average however our analysis also indicates that the returns to renting in land vary strongly with scale of production tenants who produce more have larger returns to renting in and many of the smaller producers who rent in do so at an economic loss the impacts of renting out i e participating in markets as landlords are decidedly more mixed with overall negative returns to landlords in malawi and negligible returns to landlords in zambia the findings in this article highlight the need for researchers and policymakers in sub saharan africa to stay attuned to how land rental market participation and its impacts evolve in the near future

modeling farm households price responses in the presence of transaction costs and heterogeneity in labor markets we develop a farm household model to analyze price responses of farm households this model incorporates various types of transaction costs as well as labor heterogeneity nonproportional variable transaction costs or labor heterogeneity imply that production and consumption decisions become nonseparable even when the household buys or sells labor an empirical model is estimated using data from midwest poland the results show that nonproportional variable transaction costs and labor heterogeneity significantly influence household behavior not all price elasticities however change significantly if these are neglected

debt poverty and resource management in a rural smallholder economy this paper develops a model to capture the key features of poverty credit constraints and resource management faced by poor rural households we assume that due to the existence of asymmetric information and moral hazard the household faces an increasing cost of credit as its debt equity ratio rises a household exploiting a natural resource may fall into a poverty trap but only if it is unable to afford the increasing borrowing costs implied by increasing debt to allow it to avoid such a trap or if it discounts future utility so much that a balanced growth path cannot be financed at any level of long run borrowing in contrast along an optimal balanced growth path the household s asset wealth purchased inputs resource stock and consumption increase at the same constant rate however over the long run there may be carrying capacity limits that prevent the resource from improving further the household may then direct its savings to accumulating financial assets and eventually under certain conditions may become a net creditor with resource exploitation becoming a less and less important source of its income

stochastic wealth dynamics and risk management among a poor population we use herd history data collected among pastoralists in southern ethiopia to study stochastic wealth dynamics among a poor population although covariate rainfall shocks plainly matter household specific factors including own herd size account for most observed variability in wealth dynamics we find no support for the tragedy of the commons hypothesis past studies may have conflated costly self insurance with stocking rate externalities biophysical shocks move households between multiple dynamic wealth equilibria the lowest suggesting a poverty trap according to nonconvex path dynamics these findings have broad implications for development and relief strategies among a poor population vulnerable to climatic shocks a vast economic literature on risk management rests explicitly or implicitly on the classic friedmanite permanent income hypothesis studies of portfolio management consumption smoothing social insurance and the like all depend on the canonical assumption that stochastic income realisations are drawn from a stationary income distribution leading to consumption smoothing off a stable asset base the possibility of asset accumulation connects this literature to the immense literature on the theory and empirics of economic growth

a note on execution costs for stock index futures information versus liquidity effects this paper examines execution costs and the impact of trade size for stock index futures using price volume transaction data from the london international financial futures and options exchange consistent with subrahmanyam rev financ stud 4 1991 11 we find that effective half spreads in the stock index futures market are small compared to stock markets and that trades in stock index futures have only a small permanent price impact this result is important as it helps to better understand the success of equity index products such as index futures and exchange traded funds we also find that there is no asymmetry in the post trade price reaction between purchases and sales for stock index futures across various trade sizes this result is consistent with the conjecture in chan and lakonishok j financ econ 33 1993 173 that the asymmetry surrounding block trades in stock markets is due to the high cost of short selling and the general reluctance of traders to short sell on stock markets c 2004 elsevier b v all rights reserved

the inverse relationship between productivity and farm size a test using regional data from india the farm size productivity debate for india needs little introduction it has occupied a prominent position in the agricultural economics literature since 1962 when sen observed that indian farm management data revealed an inverse relationship between farm size and yields per acre since then no fewer than twenty journal papers have appeared on this subject sen 1975 the objective of this paper is to test two hypotheses that were either not given enough attention or left unresolved in the debate the first is that the inverse relationship is valid for all of indian agriculture it is not merely a phenomenon observed in a few sample villages this means a test of the hypothesis that the small farm sector as a whole is more productive than the large farm sector in indian agriculture the second hypothesis is that the inverse relationship is true only of a traditional agriculture and that it breaks down with technical progress a methodology is developed below which uses cross sectional regional data to test the two hypotheses simultaneously on applying this methodology to indian district level data 272 districts for 1970 71 it is found that the hypothesis of the small farm sector being more productive than the large farm sector cannot be rejected at low levels of agricultural technology but can be rejected at higher levels this suggests that the inverse relationship between yields and farm size although valid for a traditional agriculture cannot be assumed to exist in an agriculture experiencing technical change

rural market imperfections and the farm size productivity relationship evidence from pakistan the subject of this article is the relationships between farm size and productivity and between farm size and profitability in the developing countries the recent controversies over the inverse size output relationship are reviewed and a framework is provided that explains the inverse relationship based on plausible assumptions about imperfections in the markets for labor land credit and risk from this framework a set of testable hypotheses are derived the hypotheses are tested on recent farm level panel data from pakistan a strong inverse relationship between farm size and yield is present in the sample even when household fixed effects are used to account for unobserved heterogeneity moreover the suggested market imperfections framework is consistent with the data

risk bearing and the theory of income distribution this paper develops the stochastic theory of distribution with a dynamic model which focuses on the role of incomplete insurance in generating inequality unlike previous work our approach takes explicit account of the reason for market incompleteness in modeling agents behaviour in particular the amount of risk borne is endogenous using a model of growth with altruism in which agents are risk averse and there is moral hazard we show that lineage wealth follows a markov process which converges globally to an ergodic distribution this also represents the long run population distribution of wealth we discuss the role of particular assumptions such as availability of production loans and unboundedness of utility in yielding the qualitative properties of the distribution of wealth the choice of occupation and the prevention of poverty traps

the relation between farm size and farm productivity the role of family labor supervision and credit constraints abstract the paper shows that if the performance of hired farmhands is affected by supervision from family members and if the availability of credit is dependent on the amount of land owned then a systematic positive or negative relationship between per acre yields and farm size will prevail a model with no supervision effects on labor productivity would predict that yields are unaffected by farm size the paper also investigates the relation between land utilization and owned holding size when land rental possibilities are limited results are shown to be compatible with various observed patterns in ldcs

does access to external finance improve productivity evidence from a natural experiment abstract we study the relation between access to finance and productivity our contribution to the literature is a clean identification of a causal effect of access to finance on productivity specifically we exploit an exogenous shift in demand for a product to expose how producers adapt their productivity in the presence of varying levels of access to finance we use a triple differences testing approach and find that production increases the most over the sample period in areas with relatively strong access to finance even in comparison with a control group this result is statistically significant and robust to a variety of controls alternative variables and tests the causal effect of access to finance on productivity that we find speaks to the larger role of finance in economic growth

how are derivatives used evidence from the mutual fund industry we investigate investment managers use of derivatives by comparing return distributions for equity mutual funds that use and do not use derivatives in contrast to public perception derivative users have risk exposure and return performance that are similar to nonusers we also analyze changes in fund risk in response to prior fund performance changes in risk are substantially less severe for funds using derivatives consistent with the explanation that managers use derivatives to reduce the impact of performance on risk we provide new evidence regarding the implications of cash flows and managerial gaming for the relation between performance and risk

land reforms poverty reduction and economic growth evidence from india recognition of the importance of institutions that provide security of property rights and relatively equal access to economic resources to a broad cross section of society has renewed interest in the potential of asset redistribution including land reforms empirical analysis of the impact of such policies is however scant and often contradictory this paper uses panel household data from india together with state level variation in the implementation of land reform to address some of the deficiencies of earlier studies the results suggest that land reform had a significant and positive impact on income growth and accumulation of human and physical capital the paper draws policy implications especially from the fact that the observed impact of land reform seems to have declined over time

national systems of biotechnology innovation complex interdependence in the global system this paper explores the relationship between national institutional context and the development of biotechnology in the united states united kingdom japan and germany national patterns in biotechnology r d are linked to the configuration of county specific institutional features into a system of innovation which supports or impedes the accumulation and diffusion of knowledge between the scientific and industrial communities building on this comparative analysis it is argued that the particular characteristics of national systems of biotechnology innovation form the basis for complex interdependence within the global system through international technological cooperation and the cross border adoption and adaptation of institutional forms and practices implications for national technological advantage and the stability of national institutional systems are discussed

asset smoothing consumption smoothing and the reproduction of inequality under risk and subsistence constraints abstract a growing literature asks whether low wealth agents can accumulate assets over time or whether they are trapped in poverty this paper develops a stochastic dynamic programming model with endogenous asset price risk to explore savings and portfolio decisions in a resource poor environment characterized by risk and subsistence constraints optimal portfolio strategies are found to bifurcate despite divisible assets and fully rational agents wealthier agents acquire a higher yielding portfolio and pursue conventional consumption smoothing poorer agents acquire a less remunerative portfolio and pursue asset smoothing rather than consumption smoothing asset based risk coping thus results in positive correlation between initial wealth and portfolio rate of return

peasant household behaviour with missing markets some paradoxes explained a model of peasant household behavior under varying degrees of household specific food and labor market failures is constructed to show that these structural features can explain several well known patterns of peasant response which have often been attributed to peculiar motives presumed specific to peasants the model explains sluggish response to cash crops prices and high instability in perceived food and labor scarcities the key role of manufactured consumer goods prices in stimulating peasants effort in cash crops production the effectiveness of taxation as opposed to incentives in stimulating cash crops production and the key role of technological change in food production to enhance cash crop production results are obtained analytically in the case of one market failure and by numerical simulation with more than one

a dynamic capabilities based entrepreneurial theory of the multinational enterprise this paper develops a dynamic capabilities based theory of the multinational enterprise mne it first reviews scholarship on the mne with a focus on what has come to be known as internalization theory one prong of this theory develops contractual transaction cost informed governance perspectives and another develops technology transfer and capabilities perspectives in this paper it is suggested that the latter has been somewhat neglected however if fully integrated as part of a more complete approach it can buttress transaction cost governance issues and expand the range of phenomena that can be explained in this more integrated framework dynamic capabilities coupled with good strategy are seen as necessary to sustain superior enterprise performance especially in fast moving global environments entrepreneurial management and transformational leadership are incorporated into a capabilities theory of the mne the framework is then used to explain how strategy and dynamic capabilities together determine firm level sustained competitive advantage in global environments it is suggested that this framework complements contract based perspectives on the mne and can help integrate international management and international business perspectives

the influence of customer scope on supplier learning and performance in the japanese automobile industry most studies of japanese supplier automaker relationships have focused on the nature of the dyadic interfirm relationship and the performance of the assembler we examine the relationship from the point of view of the supplier and argue that a broad customer scope strategy i e number of customers leads to superior performance primarily because of learning opportunities in addressing these learning opportunities we draw attention to the important distinction between relation specific and re deployable knowledge and the complementary relationship between them our analysis of 125 japanese suppliers supports the key argument that less exclusive ties may be a superior strategy the argument has important implications for vertical integration and the structure of buyer supplier relations

labor supervision and institutional conditions evidence from bicol rice farms this article analyzes labor supervision activities reported in a survey of rice farmers in the bicol region of the philippines we present a theoretical model that relates supervision intensity to institutional conditions we estimate a supervision intensity equation and control for the decision to hire labor the decision to supervise hired labor and the type of the labor contract the empirical estimates use different village level spatial and demographic indicators as proxies for institutional conditions the results are consistent with the prediction of the theoretical model that supervision increases with weaker institutional conditions

hot hands in mutual funds short run persistence of relative performance 1974 1988 the relative performance of no load growth oriented mutual funds persists in the near term with the strongest evidence for a one year evaluation horizon portfolios of recent poor performers do significantly worse than standard benchmarks those of recent top performers do better though not significantly so the difference in risk adjusted performance between the top and bottom octile portfolios is six to eight percent per year these results are not attributable to known anomalies or survivorship bias investigations with a different previously used data set and with some post 1988 data confirm the finding of persistence

rural organization and land reform in brazil the role of nonagricultural benefits of landholding abstract this article examines the effects of nonagricultural land use on agrarian organization and land reform in an economy characterized by limited credit and land rental markets the nonagricultural demand for land under credit constraint generates a potential mismatch between the distribution of land and the distribution of farming skills this disparity reduces the agricultural output if the land rental market is absent a perfect land rental market is shown to determine the highest possible agricultural output policy implications from the model include in addition to market improvements the fact that small farmers rather than landless people should be the target of redistributive land reform programs

shadow wages allocative inefficiency and labor supply in smallholder agriculture this article introduces a method for estimating structural labor supply models in the presence of unobservable wages and deviations of households marginal revenue product of self employed labor from their shadow wage this method is therefore robust to a wide range of assumptions about labor allocation decisions in the presence of uncertainty market frictions locational preferences etc we illustrate the method using data from rice producers in cote d ivoire these data like previous studies reveal significant systematic differences between shadow wages and the marginal revenue product of family farm labor we demonstrate how one can exploit systematic deviations in the present case related to household characteristics such as the land labor endowment ratio to control for both unobservable wages and prospective allocative inefficiency in labor allocation in structural household labor supply estimation

institutional reform and labor reallocation during transition theory evidence from polish agriculture abstract reallocation of agricultural labor during transition differs widely between regions and countries our analysis shows that agricultural labor reallocation in poland is determined by a the dramatic adjustment of prices and production costs caused by price liberalization and subsidy cuts b regional differences in farm organization and the impact of institutional reforms on these organizations c structural problems constraining intersectoral mobility the latter limit the benefits from the institutional reforms long term efficiency gains and sustainable rural development are conditional upon reducing such structural constraints and improving the functioning of the labor market

bringing income distribution in from the cold the title of this presidential address is chosen to highlight the way in which the subject of income distribution has in the past been marginalised for much of this century it has been very much out in the cold there are signs that in the 1990s it is being welcomed back and i shall be referring to recent research but i would like to use this occasion to give further impetus to the re incorporation of income distribution into the main body of economic analysis this abstract was borrowed from another version of this item

factor markets and resource allocation in colonial punjab it is often argued that agricultural factor markets in colonial india were underdeveloped leading to inefficient resource use and slow agricultural development however there is little econometric evidence on these issues this article outlines a model which incorporates the factor market imperfections discussed in the literature and tests the model against data from the punjab there is in the statistical sense evidence of resource misallocation however these effects are too small to be of much economic significance

an analysis of the use of derivatives by the canadian mutual fund industry in this paper we examine the use of derivatives by mutual funds in canada first both the incidence and extent of derivatives usage are low second larger growth oriented domestic equity funds are more likely to use derivatives we then compare returns and risks between derivative users and non users with the following findings 1 there exist no differences between users and non users for foreign equity funds 2 for fixed income funds users have higher returns and risks than non users 3 for domestic equity funds users have lower returns but higher risks than non users however the differentials disappear if warrants are excluded from the definition of derivatives

occupational choice and the process of development this paper models economic development as a process of institutional transformation by focusing on the interplay between agents occupational decisions and the distribution of wealth because of capital market imperfections poor agents choose working for a wage over self employment and wealthy agents become entrepreneurs who monitor workers only with sufficient inequality however will there be employment contracts otherwise there is either subsistence or self employment thus in static equilibrium the occupational structure depends on distribution since the latter is itself endogenous we demonstrate the robustness of this result by extending the model dynamically and studying examples in which initial wealth distributions have long run effects in one case the economy develops either widespread cottage industry self employment or factory production employment contracts depending on the initial distribution in the other example it develops into prosperity or stagnation

determinants and impacts of rural land market activity evidence from nicaragua summary use of data from nicaragua to examine the performance of land rental and sales markets during 1995 98 which coincide with the implementation of major macroeconomic and sectoral reforms leads to three main conclusions first even though the data point toward an inverse farm size productivity relationship and large differences in land productivity between large and small producers land markets have not led to an equalization of returns among the groups considered second both in 1995 and in 1998 land sales markets have contributed to land concentration suggesting that credit market imperfections impeded demand in land sales markets third the policy reforms undertaken after 1995 have led to a structural shift in the performance of the land rental market instead of transferring land to large owners as it did in 1995 the land market now moves land from large to small producers the quantities involved however remain limited we conclude that if it is to contribute to equity and efficiency liberalization of land sales markets has to be complemented by measures to reduce the attractiveness of speculative land accumulation furthermore measures to reduce the transaction costs of land rental e g titling and to increase effective demand from small producers e g technical assistance and credit will be needed 2003 elsevier ltd all rights reserved

local versus global separability in agricultural household models the factor price equalization effect of land transfer rights commonly employed global tests for separability between production and consumption decisions are theoretically inappropriate when the market failures creating non separabilities differentially constrain some but not all households simulated maximum likelihood estimates using chinese panel data reject the restrictions implied by a global separability test in favor of regime specific or local separability tests the estimates also show that a global approach to separability obscures the significant effect that less encumbered land transfer rights would have on shadow factor price equalization across households and allocative efficiency the findings on transfer rights suggest a resolution to the debate in china on further property rights reform copyright 2002 oxford university press

the impact of credit on peasant productivity and differentiation in nicaragua abstract an endogenous switching regressions framework is used to structure and identify the impact of credit on small farm food production in nicaragua the results which emerge weakly support the hypothesis that credit had a positive impact on production and could be expected to reduce the pattern of structurally unbalanced growth in nicaraguan agriculture however the estimated impact is of a form which implies a process of differentiation and unequal growth in the peasant sector in the wake of the new opportunities afforded by credit

the inverse relationship between size of land holdings and agricultural productivity the important relationship between the size of land holdings and agricultural productivity in developing countries has been debated intensely from early soviet debates to the extensive literature generated by the release of farm management survey fms data in india the question of returns to scale and input productivities primarily for land in traditional agriculture has been confused and clouded by strong positions and ideological predilections bhagawati and chakravarty saini 1969 and bharadwaj provide extensive bibliographies on the theoretical and empirical aspects of this problem in the indian context briefly sen 1964 1966 mazumdar 1963 1965 c h h rao 1966 1970 khusro saini 1971 bhattacharya and saini more or less endorse an inverse relationship between the land size and its productivity a p rao 1963 and rudra and bandhopadhyay do not believe in the existence of an inverse relationship and argue that no systematic relationship can be established between any two variables describing land size and productivity bharadwaj and others dismiss the statistical validity of an inverse relationship but generally accept it as a stylized fact the approach used in these statistical studies is to employ aggregate average or farm level data within a village or among different villages for all crops or a few specific ones various concepts of productivity and input variables are used the actual regressions use linear or log linear functional forms using the pooled fms data for several states in south india this paper makes an attempt to reexamine in a more general way the relationship between the size of land holdings and agricultural productivity this study employs the transcendental logarithmic translog function to formalize the relation between output and an arbitrary number of inputs the translog function is not locally constrained by assumptions of homogeneity or additivity estimates of output elasticity with respect to land size for various values of cooperating inputs will indicate whether the alleged inverse relationship holds in any or all circumstances

the distributive impact of land markets in uganda abstract this article presents first hand evidence about land distribution and the impact of land markets in central uganda this area is characterized by unequal distribution of land inheritance rural rural migration and active land markets we show that land markets and particularly land purchases tend to reduce the initial inequality in the initial inherited distribution of land land purchases by landless farmers in their native village represent an important part of this adjustment

climbing the development ladder economic development and the evolution of occupations in rural china we study how occupations evolve across space and time during the development of an economy using a data set on more than 200 villages from 8 provinces in china we examine the main occupations that have characterised china s labour markets since the economic reforms our findings reveal a systematic evolutionary pattern of occupational emergence the evolution of occupations proceeds from traditional and fairly simple forms of subsistence agriculture to modern more complex manufacturing and service firms our findings suggest that rural development in china is being built by a process that can be described by the climbing of a development ladder with each step up the ladder denoting the economy s transition into a more complex occupational regime

hierarchies markets and power in the economy an economic perspective this paper adopts the transaction cost economics perspective for purposes of examining hierarchies markets and power in the economy transaction cost economics works out of an economizing perspective in which markets and hierarchies are alternative modes of governance and the object is to ascertain which transactions go where and why the role of power in this setup is strictly limited partly because power tends to be myopic transactions are not examined in their entirety and partly because it is tautological power needs to be operationalized whereupon the refutable implications that accrue to this perspective can be derived copyright 1995 by oxford university press

wealth risk and activity choice cattle in western tanzania abstract imperfect credit markets force households to use their savings for investment profitable activities often require lumpy investments limiting entry by poorer households resulting in increasing welfare differences in tanzania cattle are a profitable but lumpy investment and a liquid asset for consumption smoothing richer households own substantial cattle herds while poorer households specialize in low return low risk activities a dynamic programming model and simulations are presented to analyze entry into asset accumulation under income risk the evidence suggests that households with lower endowments are less likely to own cattle and returns to their endowments are lower

mimetic and experiential effects in international marketing alliance formations of us pharmaceuticals firms an event history analysis alliances are recognized as an indispensable tool for managers operating in a global business environment and as a fundamental stage of the internationalization process of the firm drawing on a co evolutionary framework this article investigates the mimetic and experiential effects in international alliance formation we focus on a critical unresolved issue in the literature what is the role of mimetic behavior and previous alliance experience in mitigating the uncertainty associated with engaging in cross border operations an event history analysis of 792 international marketing alliance formations initiated by 317 firms in the us pharmaceutical industry is employed to test the hypotheses the findings of two different hazard rate models reveal significant complex effects of density and cross border alliance experience on the propensity to engage in new international marketing alliances

mutual fund volatility timing and management fees this paper shows that compensation incentives partly drive fund managers market volatility timing strategies larger incentive management fees lead to less counter cyclical or more pro cyclical volatility timing but fund styles or aggregate fund flows could also account for this relation therefore we control for them and find that the relation between fees and volatility timing still holds results show that less aggressive fund styles are associated with pro cyclical volatility timing and that volatility timing and flow timing are negatively related we also find that pro cyclical timing mostly improves funds average excess returns sharpe ratios and alphas

rural wages labor supply and land reform a theoretical and empirical analysis land reform is one of the most mentioned of the theoretical policy instruments discussed in the development literature yet relatively little attention has been paid to the wage rate consequences of such a program despite the fact that perhaps more than one half of rural families in a developing country receive a substantial proportion of their income from wage earnings in agriculture one reason for this lacuna may be that the determination of wages and family labor supply in the agricultural sector of ldcs has also been somewhat neglected particularly in the context of a heterogeneous labor force 2 the subsistence or institutional wage models of w arthur lewis john fei and gustav ranis and gerald rodgers for instance offer no theory of how rural wage levels or differentials are set and thus provide little guidance on how wage rates would be affected by changes in land ownership patterns more recently pranab bardhan and t n srinivasan david newbery and clive bell and pinhas zusman who formulate general equilibrium market or bargaining models determining endogenously the rental share paid by tenant sharecroppers have assumed that agricultural wage rates are exogenous or determined only by nonagricultural factors all of these models assume that rural labor is homogeneous another reason why the potential wage impact of a land reform program may have received little attention is that models of peasant family behavior such as those of a k sen dipak mazumdar and robert mabro typically embody two restrictive assumptions which would tend to make the equalization of landholdings appear wage augmenting although this implication has never been formally derived these assumptions are that 1 agriculture is dualistic with small farm families facing lower shadow prices of labor leisure than large farm landlords because of impediments to labor mobility and 2 agricultural households are dichotomous small farmers employ family labor and maximize utility while large farms only utilize wage labor and maximize profits data from a 1970 71 allindia survey of over 5 000 households collected by the national council of applied economic research3 indicate however that almost all cultivator households large and small participate actively in the labor market as either buyers or sellers of labor services with almost 88 percent of households cultivating a gross cropped area less than 1 5 acres utilizing some hired labor seventynine percent of these small farm households associate professor yale ujniversity the research embodied in this paper was supported in part by a grant from the ford and rockefeller foundations program in support of social science and legal research on population policy and with funds from the u s agency for international development under order no aid otr 1432 helpful suggestions and comments were provided by james l mccabe mark gersovitz an anonymous referee the managing editor and members of the economic growth center yale university i am also grateful to the members of the research program in development studies princeton university for the use of their facilities research assistance was provided by james devine anne morgan and roberta robson inotable exceptions are r albert berry mark gersovitz and m a rahman all of these authors however employ geometric analyses with differing assumptions leading to wholly different predictions regarding wage effects none consider the heterogeneity of agricultural labor pay attention to questions of stability or attempt to apply their models to data 2lnformation on the differential impact of alternative agricultural policies including land reform on sex or age specific wage rates is not only important in settling income distribution and equity issues but as suggested in an article by the author and robert evenson may have significant implications for population growth and schooling as well 3for a more detailed discussion of these data see the author

land distribution and international agricultural productivity the unequal distribution of agricultural land is often cited as a source of inefficiency in agriculture previous cross country studies of agricultural productivity differences though have not considered land inequality this article addresses this issue by using cross country data on inequality in operational holdings of agricultural land from deininger and squire 1998 in an estimation of an agricultural production function the gini coefficient for land holdings is found to have a significant negative relationship with productivity this is consistent with the existence of heterogeneity in productivity by farm size within countries a one standard deviation drop in the gini coefficient implies an increase in productivity of 8 5

on the timing of marriage cattle and weather shocks abstractin this paper we focus on the timing of marriage of women whose marriages are associated with bride wealth payments these payments concern transfers from the family of the groom to the bride s family unmarried daughters could therefore be considered part of the asset portfolio of the household that at times of need can be cashed we investigate both theoretically and empirically to what extent the timing of marriage of a daughter is affected by the economic conditions of the household from which she originates we distinguish household specific wealth levels and two types of shocks correlated weather shocks and idiosyncratic wealth shocks we estimate a duration model using a unique panel survey of zimbabwean smallholder farmers the estimation results support the hypothesis that the timing of marriage is affected by household characteristics girls from households that experienced a negative idiosyncratic wealth shock are more likely to marry

risk and household grain management in developing countries a dynamic model is presented of a household s joint production storage and trade decisions when facing transaction costs and risk in prices and yields grain management decisions balance the goals of maximising profits and reducing consumption price risk model solutions calibrated to chinese data show that grain s consumption role makes it an attractive form of precautionary saving even when households have access to credit the joint nature of production and savings decisions limits the income loss associated with risk coping and the desire to store grain can explain why subsistence households are frequently net purchasers but rarely net sellers of grain

behavioural and material determinants of production relations in agriculture in this essay we develop a framework for analysing the major institutions governing the production and exchange of output and the primary factors of production in rural areas the analysis incorporates general considerations of risk and information constraints jointly with the principal material attributes of agriculture and of agricultural production factors the framework is used to analyse barriers to the existence of the major intertemporal and factor markets it is applied specifically to land scarce environments for which it provides an internally consistent explanation for many of the well documented institutional features of such settings in addition the analysis provides new implications for among other phenomena the inter relationships among ownership holdings operational scale family size and factor productivity for the scarcity of animal rental markets and use of animals as collateral for the renting out of land by small landowners and for the existence of plantations for certain crops

a theory of trickle down growth and development this paper develops a model of growth and income inequalities in the presence of imperfect capital markets and it analyses the trickle down effect of capital accumulation moral hazard with limited wealth constraints on the part of the borrowers is the source of both capital market imperfections and the emergence of persistent income inequalities three main conclusions are obtained from this model first when the rate of capital accumulation is sufficiently high the economy converges to a unique invariant wealth distribution second even though the trickle down mechanism can lead to a unique steady state distribution under laissez faire there is room for government intervention in particular redistribution of wealth from rich lenders to poor and middle class borrowers improves the production efficiency of the economy both because it brings about greater equality of opportunity and also because it accelerates the trickle down process third the process of capital accumulation initially has the effect of widening inequalities but in later stages it reduces them in other words this model can generate a kuznets curve

food insecurity income inequality and the changing comparative advantage in world agriculture i would like to argue in this article that in the process of economic development in land poor countries in asia agriculture faces three distinctly different problems food insecurity sectoral income inequality and the declining food self sufficiency associated with the declining comparative advantage in agriculture at the high income stage massive imports of food grains to asia if they occur will aggravate the world food shortage which will have significant implications for the poverty incidence in the world i argue that in order to avoid such a tragedy asia should expand farm size to reduce labor cost by adopting large scale mechanization sub saharan africa should realize a green revolution in grain production and latin america should further expand its grain production capacity

equilibrium credit rationing of small farm agriculture it is often argued that externally imposed contractual restrictions lead to inequitable credit rationing this paper argues that unrestricted laissez faire markets may also inequitably ration credit a formal model which grants borrowers autonomy in credit application and use demonstrates that adverse incentive and selection effects may cause banks to endogenously impose interest rate restrictions and ration small farms out of the credit market consequently liberalization of financial markets may be insufficient to guarantee small farms access to credit

impacts on rural poverty of land based targeting further results for bangladesh abstract landholding class has been widely advocated as a targeting indicator for fighting rural poverty in south asia and elsewhere supporters have pointed to the correlation between poverty and lack of land and have also claimed that land based targeting raises output the paper tries to assess the impact on rural poverty in bangladesh of a benchmark policy under seemingly ideal conditions generalizing earlier results of ravallion 1989 on improved data poverty is reduced though the maximum gains turn out to be small even allowing for pro poor productivity effects consistent with the farm size productivity relationship in bangladesh the gains are likely to be even smaller under real world incentive and political economy constraints

is small beautiful farm size productivity and poverty in asian agriculture the debate on the relationship between farm size and productivity has gone through a complete circle in the 1960s it was perceived that small farms were efficient because they can fully use their resources particularly family labor and they can monitor their production activities closely but in the 1970s and 1980s as many asian countries rapidly moved towards industrialization and urbanization small farms were considered a major obstacle in this process

optimal farm size in an uncertain land market the case of kyrgyz republic this article applies a real options model to the problem of land development making use of the 1998 2001 kyrgyz household budget survey we show that when the hypothesis of decreasing return to scale holds the relation between the threshold value of revenue per hectare and the amount of land cultivated is positive in addition the relation between the threshold and the amount of land owned is positive in the case of continuous supply of land and negative when there is discontinuous supply of land the direct consequence is that in the first case smaller farms will be more willing to rent land and exercise the option where in the second case larger farms will exercise first the results suggest three main conclusions i the combination of uncertainty and irreversibility is an important factor in land development decisions ii farmer behavior is consistent with the continuous profit maximization model and iii farming unit revenue tends to be positively related to farm size once uncertainty is properly accounted for

poverty and landownership the author studies how landownership affects labor allocation income distribution and poverty in less developed countries he focuses on three prototypes of ownership classes landlords smallholders and landless people agents are identical except for their ownership of assets on the basis of optimizing behavior they divide into urban workers in the modern sector urban workers in the informal sector agricultural laborers subsistence farmers and landlords the impact of land reform on production and poverty depends on the amount of fertile land per capita a more egalitarian distribution of landownership reduces poverty where land is scarce but not where land is abundant copyright 1992 by american economic association

origins of exploitation and class value theory of pre capitalist economy both the class position of agents and their status as exploiters or exploited is endogenously determined as they optimize against asset constraints which limit their capacity to produce revenue the class exploitation correspondence principle cecp asserts that class and exploitation status are related in a classical way it is further shown that the class structure associated with a labor market can be generated isomorphically by a credit market demonstrating the functional equivalence of these markets morever these results hold in models of precapitalist subsistence economy showing that the phenomena of marxian exploitation and class are applicable in economic mechanisms other than capitalist ones the possibility for a general theory of exploitation is thereby suggested

income distribution and macroeconomics this paper analyzes the role of wealth distribution in macroeconomics through investment in human capital it is shown that in the presence of credit markets imperfections and indivisibilities in investment in human capital the initial distribution of wealth affects aggregate output and investment both in the short and in the long run as there are multiple steady states this paper therefore provides an additional explanation for the persistent differences in per capita output across countries furthermore the paper shows that cross country differences in macroeconomic adjustment to aggregate shocks can be attributed among other factors to differences in wealth and income distribution across countries

the diversity of land markets and regulations in europe and some of its causes abstractthe creation of optimal land institutions attracted renewed attention in the 1990s because of its central role in the transition process in former communist countries in the former soviet union and eastern europe and more recently because of large scale land investments in developing countries this article documents the existence of large variations in land institutions markets and regulation using current and historical data from western and eastern europe it then offers explanations for these differences and draws implications for the role and optimality of land institutions in development with special reference to the current debate on large scale land acquisitions

derivative use fund flows and investment manager performance abstract prior literature which examines the use of derivatives by investment managers does not discern between different types of derivative trading strategies this study is the first to examine and gather data on a particular type of derivative trading strategy undertaken by investment managers we examine the extent to which equity fund managers use index futures to manage fund flows and the effect this has on their alpha and market timing measures of performance our results show that funds that do not use derivatives exhibit lower returns and negative market timing skills when they experience fund flow the performance of funds that use derivatives however is independent of investor s liquidity demands in fact the unconditional performance of the average user fund is statistically equivalent to the performance of the average non user fund conditional on zero fund flow our results provide evidence that derivatives can be beneficial for mutual fund holders under certain conditions

why are capitalists the bosses this paper addresses the question why does capital typically hire labor rather than the other way around it models a situation in which a capitalist owner of money capital can choose between lending out his capital for production and using it to set up production under his own supervision it is demonstrated that the moral hazard of potential borrowers on account of limited liability provides the capitalist with the incentive to become a firm owner supervising hired labor the capitalist s choice is endogenized in terms of his opportunity cost of time it is argued that moral hazard with respect to the use of borrowed capital is an important determinant of the social hierarchy in the workplace copyright 1989 by royal economic society

the impact of market friendly reforms on credit and land markets in honduras and nicaragua summary this article explores the impacts on credit access and agrarian structure of land market liberalization policies undertaken in honduras and nicaragua during the 1990s like liberalization efforts pursued in many latin american countries these market friendly reforms were designed to activate land transfers and enhance agricultural efficiency in large part by improving the access of the rural poor to both credit and land markets panel data sets gathered in honduras and nicaragua are used to compare title credit and land access patterns before and after the reforms descriptive nonparametric regression analyses show that despite major gains in titling across the land size spectrum and some increase in land market activity the other hoped for improvements in credit and land access did not occur and appear unlikely to occur without further policy attention to credit markets

impacts of prices and transactions costs on input usage in a liberalizing economy evidence from tanzanian coffee growers despite improvements in production incentives agricultural output in africa remained sluggish through the 1990s low use of purchased inputs may be part of the cause of persistently low productivity in african agriculture this article analyzes the roles of relative prices and transactions costs in explaining low use of chemical inputs among tanzanian coffee growers a sample selection model indicates that output prices exert great influence on input purchases and that both fixed and variable transactions costs affect input use decisions travel costs in input and output markets have distinct effects on input usage implying distinct avenues for interventions to promote more intensive use of agricultural inputs

the behavior of stock prices around institutional trades all trades executed by 37 large investment management firms from july 1986 to december 1988 are used to study the price impact and execution cost of the entire sequence package of trades that we interpret as an order we find that market impact and trading cost are related to firm capitalization relative package size and most importantly to the identity of the management firm behind the trade money managers with high demands for immediacy tend to be associated with larger market impact financial economists have long studied the equity trading process and its impact on stock prices much prior empirical research isolates individual trades and analyzes the behavior of the stock price around each trade see for example kraus and stoll 1972a holthausen leftwich and mayers 1987 1990 keim and madhavan 1991 petersen and umlauf 1991 hausman lo and mackinlay 1992 and chan and lakonishok 1993 evaluating the behavior of stock prices around trades provides a means of discriminating among various hypotheses as to the elasticity of the demand for stocks yields an estimate of the cost of executing trades and a measure of the liquidity of a market and permits tests of different models of the determination of quotes and transaction prices for many institutional investors however even a moderately sized position in a stock may represent a large fraction of the stock s trading volume accordingly an investment manager s order is often broken up into several trades it is often misleading therefore to consider an individual trade as the basic unit of analysis in the study of trading activity and its effects on prices this paper uses the record of trades executed by 37 large investment manage

confronting the risk of asset loss what role do livestock transfers in northern kenya play abstract in many low income high risk environments households participate in informal risk sharing institutions involving inter household transfers this study focuses on asset transfers and asset risk the influence of past behavior on access to transfers and wealth differentiated transfer behavior panel data on livestock transfers in northern kenya are analyzed three explanations of livestock transfers are investigated ex post insurance ex ante precautionary savings and redistribution findings indicate that livestock transfers are of limited effectiveness in addressing asset risk and avoiding poverty the findings have implications for both research on risk sharing institutions and for the design of development policies in pastoral areas

does supervision matter some hypothesis tests using indian farm level data abstract a model is developed and estimated to test for heterogeneity of family and hired labor in agricultural production and to estimate the impact of employer supervision on the productivity of hired labor plot level data are used from a rice growing village in semi arid tropical india the hypothesis that family and hired labor are homogeneous inputs was rejected results indicate that family member supervision is required to increase hired labor productivity output loss attributable to operating at reduced supervision intensity was greater than 10 on over 40 of the plots

the international biotechnology industry a dynamic capabilities perspective this paper extends our understanding of the diffusion of technology across firms and nations the dynamic capabilities perspective in its micro and macro version provides the theoretical framework for an explanation of the international organization of the biotechnology industry we address two interrelated aspects of the phenomenon of international diffusion organizational form and geographical flows an examination of the empirical profile lends support to the dynamic capabilities argument

inequality as a determinant of malnutrition and unemployment policy this paper explores the policy implications that are obtained once it is recognized that at low nutrition intakes a person s productivity is an increasing function of intake in the context of a fully general equilibrium model it is shown that if aggregate assets in an economy are neither large nor small certain patterns of lorenz improving asset redistributions or nutrition transfers increase aggregate output and reduce the volume of involuntary unemployment and the incidence of undernourishment copyright 1987 by royal economic society

does sharecropping affect long term investment evidence from west bengal s tenancy reforms in india land reform has been high on the political agenda since independence in 1947 and early efforts at abolishing intermediaries are widely credited with having brought about significant social benefits the most prominent type is tenancy reform as it does not extinguish landlords ownership rights tenants who may have benefited from rent ceilings and cannot be evicted still have to pay annual share rent this weakness of rights may fail to create the incentives for effort supply and long term investment that have underpinned the success of land reforms elsewhere effectively adding a dynamic inefficiency to the disincentives created by the marshallian inefficiency of sharecropping this could imply that despite the high political price of implementing land reform in india the schemes so far have failed to reach their productivity and poverty reduction potential

should african rural development strategies depend on smallholder farms an exploration of the inverse productivity hypothesis in africa most development strategies include efforts to improve the productivity of staple crops grown on smallholder farms an underlying premise is that small farms are productive in the african context and that smallholders do not forgo economies of scale a premise supported by the often observed phenomenon that staple cereal yields decline as the scale of production increases this paper explores a research design conundrum that encourages researchers who study the relationship between productivity and scale to use surveys with a narrow geographic reach when policy would be better served with studies based on wide and heterogeneous settings using a model of endogenous technology choice the authors explore the relationship between maize yields and scale using alternative data since rich descriptions of the decision environments that farmers face are needed to identify the applied technologies that generate the data improvements in the location specificity of the data should reduce the likelihood of identification errors and biased estimates however the analysis finds that the inverse productivity hypothesis holds up well across a broad platform of data despite obvious shortcomings with some components it also finds surprising consistency in the estimated scale elasticities

sme internationalization modes in the german biotechnology industry the influence of imitation network position and international experience in this article we reveal how network enabled imitation processes impact young small and medium sized enterprises smes internationalization and how a firm s network position as well as its experiential knowledge moderate imitative behavior in internationalization modes building on institutional network and organizational learning theory we suggest that firms imitate the internationalization modes of their peers in their network moreover we argue that a firm s imitation propensity depends on two important boundary conditions network position and past experience applying a longitudinal event history analysis to analyze the complete population of 977 german biotechnology firms between 1996 and 2012 largely supports our hypotheses our findings reveal that firms imitate the internationalization modes of their peers in a precise manner this implies that the imitation of others can initially serve as a presumably convenient low risk shortcut to a planned or experience driven internationalization process furthermore our results confirm that this imitation process is channeled through formal network relations and that central network positions that are associated with superior information access enhanced legitimacy and status may promote deviating behavior acknowledging the interplay of different learning sources our findings additionally show that initial internationalization mode choices of smes can have a lasting effect on subsequent internationalization behavior overall our study contributes to a more nuanced view of imitative behavior of internationalizing smes and its boundary conditions and highlights future research opportunities that exist for considering imitation and its implications in international business research

a century long perspective on agricultural development this article strategically surveys the past century s literature on agricultural development we organize the discussion around three grand themes that reveal the richness of agricultural development as an intellectual endeavor first we explore the role of agriculture in the broader development process from a macroeconomic and political economy perspective we then examine the role of technological and institutional change in successful agricultural development finally the focus turns to a microeconomic perspective on agricultural household decision making and the problems of imperfect and missing markets asymmetric information and transactions costs that lead to widespread apparent inefficiency and disequilibrium

one kind of freedom poverty dynamics in post apartheid south africa abstract a 1993 south african living standards survey documented the legacy of apartheid in the form high levels of inequality and human insecurity drawing on a 1998 re survey of households in the 1993 study this paper explores whether this legacy has been superseded or whether apartheid s end has been only one kind of freedom that has left households in a poverty trap from which they cannot escape after proposing a theoretically grounded dynamic poverty typology that distinguishes stochastic from structural poverty transitions the paper goes on to estimate that significant numbers of the south african poor are potentially trapped in a structural poverty trap and lack the means to escape poverty over time

poverty and land redistribution abstract despite a theoretical literature that promises that land transfers will have large impacts on the well being of poor households well identified empirical evidence on the efficacy of land redistribution is scarce in an effort to fill this gap this paper examines south africa s land redistribution for agricultural development lrad program we exploit features of lrad program implementation to extract exogenous variation in whether and for how long applicant households enjoyed land transfers binary treatment estimates which compare treated with untreated households show that beneficiary households on average experienced a 25 increase in per capita consumption our preferred continuous treatment estimates which analyze only the subset of treated households identify the impact time path of land transfers on consumption these estimates show that living standards initially drop and then after 3 4 years rise to 150 of their pre transfer level these results are statistically significant and robust to a statistically more conservative identification strategy

the dynamics of the wealth distribution and the interest rate with credit rationing are uniquely determined and wealth dispersion among individuals or firms is irrelevant introducing credit rationing into the solow model modifies these conclusions multiple stationary interest rates and wealth distributions can exist because higher initial rates can be self reinforcing through higher credit rationing and lower capital accumulation the wealth accumulation process is ergodic in every steady state but wealth mobility is lower with higher steady state interest rates aggregate output is higher in steady states with lower interest rates because credit is better allocated short run interest rate or distribution shocks can be self sustaining and can have long run effects on output through the induced dynamics of the wealth distribution and credit rationing
