from food availability to nutritional capabilities advancing food security analysis abstract this paper has a threefold objective first it provides a comprehensive review of different approaches to analysing food security second it highlights the added value provided by the capability approach and the human development paradigm third it proposes a methodology to assess food security through this approach our proposal entails three basic steps 1 analysis of food entitlements 2 analysis of nutritional capabilities and 3 analysis of the capability to be food secure in this way we can move beyond income entitlement or livelihood related frameworks and identify the root causes of food insecurity food insecurity can be the result of a lack of education health or other basic capabilities that constitute people s wellbeing this therefore allows situating the study within the broader area of wellbeing and development

growth and profitability of small and medium sized enterprises some welsh evidence foreman peck j makepeace g and morgan b 2006 growth and profitability of small and medium sized enterprises some welsh evidence regional studies 40 307 319 policy makers throughout the organization for economic co operation and development oecd are keen to promote the development of small and medium sized enterprises smes by a wide variety of means the present study of over 1600 welsh smes casts doubt on the effectiveness of doing so by grants by encouraging trade associations by pursuing current initiatives in training or by stimulating innovation as defined by sme management on the other hand it finds that support for selective information technology investment and for marketing planning could be beneficial additional results that might be addressed by policy are short termism by older managers preferring current to future profits more than younger managers signs that fixed costs of tax compliance bear substantially more heavily on the profitability of smaller smes and evidence

intertemporal production and intertemporal substitution in output supply and input demand abstractthis article presents an intertemporal model of production with multiple inputs to investigate substitution opportunities facing firms over time the firm s intertemporal profit maximization problem is characterized with the familiar cost function and various intertemporal substitution elasticities are delineated for output supply and input demand the absence of intertemporal substitution in production can imply production smoothing and allowance for intertemporal substitution in labour demand reinforces the prediction of the real business cycle model for aggregate us manufacturing we find substantial substitution in output supply and labour demand over time due to intertemporal changes in output price and wage rates

land clearance and social capital in mountain agro ecosystems the case of opuntia scrubland in ayacucho peru abstract opuntia scrublands are important ecological economic systems in rural andean areas they provide goods for peasants diet and animal feed as well as cochineal insects a highly valued source of dyes land clearance on these scrublands promotes changes in land use from nonproductive wilderness to cochineal and fruit harvest areas grazing lands and fuel wood supply zones here we empirically explore the role of social capital on land clearance based on a case study of the humanga region of ayacucho peru the literature on social capital is showing evidence of the positive effect of social capital on development actions and on environmental conservation in rural areas of developing countries such as participatory forest management here the notion of social capital is captured by the idea that some features of social organization such as networks facilitate coordination and cooperation within the peasant communities that help in managing different economic activities both on and off farm the habilitation of the scrublands in the andean mountain environment could be generating negative externalities as a consequence of altering the vegetation cover such as soil erosion because the benefits arising from land clearance activities are obtained by cochineal collecting households and the negative environmental effects are costs imposed upon noncochineal collectors the social capital associated with scrubland habilitation could be perverse from an agro environmental viewpoint and a revision of some government policies and of some ngos actions for rural development through the promotion of various community networks in this deprived area could be needed

green revolution in sub saharan africa implications of imposed innovation for the wellbeing of rural smallholders green revolution policies are again being pursued to drive agricultural growth and reduce poverty in sub saharan africa however conditions have changed since the well documented successes of the 1960s and 1970s benefitted smallholders in southern asia and beyond we argue that under contemporary constraints the mechanisms for achieving improvements in the lives of smallholder farmers through such policies are unclear and that both policy rationale and means of governing agricultural innovation are crucial for pro poor impacts to critically analyze rwanda s green revolution policies and impacts from a local perspective a mixed methods multidimensional wellbeing approach is applied in rural areas in mountainous western rwanda here malthusian policy framing has been used to justify imposed rather than induced innovation the policies involve a substantial transformation for rural farmers from a traditional polyculture system supporting subsistence and local trade to the adoption of modern seed varieties inputs and credit in order to specialize in marketable crops and achieve increased production and income although policies have been deemed successful in raising yields and conventionally measured poverty rates have fallen over the same period such trends were found to be quite incongruous with local experiences disaggregated results reveal that only a relatively wealthy minority were able to adhere to the enforced modernization and policies appear to be exacerbating landlessness and inequality for poorer rural inhabitants negative impacts were evident for the majority of households as subsistence practices were disrupted poverty exacerbated local systems of knowledge trade and labor were impaired and land tenure security and autonomy were curtailed in order to mitigate the effects we recommend that inventive pro poor forms of tenure and cooperation none of which preclude improvements to input availability market linkages and infrastructure may provide positive outcomes for rural people and importantly in rwanda for those who have become landless in recent years we conclude that policies promoting a green revolution in sub saharan africa should not all be considered to be pro poor or even to be of a similar type but rather should be the subject of rigorous impact assessment such assessment should be based not only on consistent objective indicators but pay attention to localized impacts on land tenure agricultural practices and the wellbeing of socially differentiated people

poverty and environmental degradation in the nicaraguan hillsides abstract this article questions the assumption of poverty as a major cause of environmental degradation examining five environmentally harmful natural resource management practices in the nicaraguan hillsides it shows that the immediate agents of environmental degradation are the nonpoor farmers not the poorest it argues that to analyze the causal links between poverty and environment a distinction between poverty as a state of deprivation and poverty as a relational phenomenon is necessary finally the article warns that the often strategic reference to poverty as the major cause of environmental degradation made by nonpoor and poor farmers may lead to negative environmental impacts

institutional design of public agencies and coproduction a study of irrigation associations in taiwan abstract the provision and production of many public goods and services involve the joint effort of government officials and citizen users this paper examines the successful experience of irrigation governance and management in taiwan as a means of understanding how joint efforts can be established and sustained through institutional arrangements several principles for institutional design including a careful definition of the scope of farmers participation complementarity of interests between individuals reduction of asymmetries involved in the use of authority and the existence of domains of autonomy are identified as instrumental to the success in taiwan

rational expectations and the effect of exchange rate intervention on the exchange rate a theoretical model is proposed in which the exchange rate is affected by current and capital account transactions and the central bank intervenes in the foreign exchange market by buying and selling foreign exchange the effects of this intervention on the exchange rate are explored under the assumption that exchange rate expectations are formed rationally and solutions are obtained for the perfect and imperfect foresight cases the paper concludes with a discussion of the non optimality of time inconsistent policies when exchange rate expectations are rational

on intertemporal substitution and aggregate labor supply in this paper the author presents an econometric investigation of t he implications of the intertemporal substitution hypothesis for aggregate employment in the united states the tests are based on a version of the hypothesis with time separable preferences on the basis of the evidence produced the hypothesis is quite successful in explaining fluctuations in aggregate employment although almost totally unsuccessful in accounting for fluctuations in employee hours these findings suggest that the hypothesis might have an important role to play in macroeconomic modeling although they contradict attempts to account for aggregate fluctuations solely in terms of continuous competitive equilibrium in labor markets copyright 1987 by university of chicago press

socio economic impacts of jeevika a large scale self help group project in bihar india summary policymakers have invested billions of dollars over the past two decades on projects which target poverty reduction by institutional mobilization of the poor unfortunately evidence on the efficacy of such projects is few and far between this is an outcome of the complexity of these projects we consider results from jeevika a large scale rural livelihoods program in bihar india we use a retrospective survey instrument coupled with psm techniques to find that jeevika has engendered some significant results in restructuring the debt portfolio of these households additionally there is evidence on women s empowerment as measured by various dimensions

the efficient estimation of econometric models with rational expectations the efficient estimation of econometric models with rational expectations by the substitution method usually entails the use of a non linear simultaneous equations estimator and hence is not very attractive computationally it is shown that for a wide class of problems efficient estimates can also be obtained with standard estimation methods if instead an errors in variables approach is used for many other problems although not providing fully efficient estimates because rationality is not imposed the errors in variables method will still have a strong appeal because otherwise it uses all of the structural information in the model unlike the substitution method when an incomplete information set is used it guarantees consistent estimates and it is easy to compute

money and the business cycle with one period nominal contracts a modified version of the nominal contract developed by j a gray 1976 and s fischer 1977 is introduced in a general equilibrium model with money which has been used in the real business cycle literature money is introduced in the model through cash in advance constraint two kinds of contracts are examined namely a nominal wage contract and a nominal price contract the nominal wage contract improves the fit of the model in many respects the nominal price contract increases the output volatility enormously but it has some unrealistic features

weekly employee hours weeks worked and intertemporal substitution abstract we show that the representative consumer model fits the aggregate consumption and employment data well if a choice of work is allowed both at the intensive and extensive margins the structural preference parameters recovered from the estimation of the euler equations of the model are economically meaningful and the null hypothesis of the overidentifying restrictions implied by our model is far from being rejected we find that the shares in preferences associated with leisure time in the weeks off and in the workweeks are quite large and about equal our estimates also uncover relatively large intertemporal substitution elasticities

an intertemporal model of industrial exit a finite horizon model of industrial exit is developed after an initial lag most exits are by young firms the duration of the lag is positively related to sunk entry costs but not due to the fallacy of sunk costs the conception of entry differs from previous research as a result not all entrants are identical and firm size affects the rate of learning on average larger new firms last longer entrepreneurs in declining firms act more lazily as the firm declines a number of empirical observations about declining firms are organized by the model

capital controls and balance of payments crises abstract the theory of balance of payments crises shows that under perfect foresight a system of fixed exchange rate is not sustainable in the presence of diverging economic policies in this paper it is shown how and why capital controls succeed in maintaining the principle of a fixed but adjustable parity both cases of a devaluation and a revaluation are considered and a condition for a parity change to be credible is presented

generalising gibrat using chinese evidence founded on fieldwork this paper reports on determinants of small firm growth and survival using fieldwork evidence collected by face to face and telephone interviews it extends the basic size age model to a comprehensive growth model with two types of additional explanatory variables firm specific and business environmental estimation is by log linear regression on chinese cross section data with corrections for sample selection bias and heteroskedasticity our results from the comprehensive model highlight the importance of location choice and customer orientation for the growth of chinese private firms

the impact of education experience and inner circle advisors on sme performance insights from a study of public development centers in this study we investigate the effects of entrepreneurial human capital on sme performance using data on 2 713 smes within the european union performance was measured in two ways profitability as roa and productivity as revenue per employee results indicate that both profitability and productivity are positively related to industry specific knowledge possessed by the ceo owner prior to starting up the firm and the general business knowledge acquired once the firm is up and running experience as a result of having previously worked in a firm in the same industry before starting a business was related to productivity but there is no relation with profitability there is a link between performance and inclusion of other ceo owners in the founder s inner circle of advisors this relationship is positive when the advisor s venture has experienced failure and negative when the advisor s venture has been successful we discuss the significance of these findings for research and practice

the role of natural capital in sustaining livelihoods in remote mountainous regions the case of upper svaneti republic of georgia in the greater caucasus of the republic of georgia proponents of a new ski tourism zone and long term timber concessions claim that new wage opportunities will benefit households these developments will also limit access to common pool resources cprs this study uses the sustainable livelihoods framework to identify the conditions under which a development strategy will improve livelihood outcomes in the region analysis of original household survey data in depth interviews and field observation reveals that households depend on cprs for a range of market and non market benefits low income households depend on cprs for up to 60 of their total income ols regression estimates show that households in villages farthest from market centers have a higher income dependence on cprs and are more likely to participate in forest use activities a majority of households report that there are few available substitutes to improve livelihood outcomes a development strategy should secure access to market benefits from cprs or wage income must increase in proportion to lost cpr income and affordable substitutes must be provided access to non substitutable components of cprs must be secured and the distribution of changes in access to natural capital and new wage opportunities must be accounted for

the labour market in an equilibrium business cycle model abstract this paper extends the basic multimarket model of lucas 1973 to explicitly consider the labour market it builds on an important distinction between the product wage entering the decision function of firms and the real wage entering the decision function of workers because of the unobservability of the price level workers make forecasting errors in trying to calculate their real wage despite having rational expectations this gives rise to a phillips curve the major new result of the paper is the demonstration that wages are less variable than prices which offers an equilibrium interpretation of wage stickiness

diversification strategies and adaptation deficit evidence from rural communities in niger summary the paper provides fresh empirical evidence on the adaptation process in niger rural communities using original longitudinal socio economic panel data merged with granular geo referenced climatic information we identify the main drivers and impacts of crop and labor diversification which constitute two livelihood strategies on moderating the adaptation deficit in doing so we account for the interdependence between the two diversification practices and potential reverse causality between welfare outcomes and diversification behavior moreover we condition the impacts of diversification on different sections of the welfare distribution to capture potential non linear effects our results reveal that the diversification has positive and significant welfare impacts when most vulnerable households rely on it as an adaptation strategy to mid run climate variability and as a coping strategy to short run market shocks at the same time our results find lower but still positive impacts for well endowed households that are likely to diversify their activity portfolio given the very limited presence of policy support we conclude that the rural nigerien communities are characterized by a large and autonomous adaptation response which constitutes a key leverage mechanism for policy makers we thus suggest government interventions aimed at supporting the most important diversification drivers but also aimed at straightening some channels such as network infrastructures or the promotion of local crop varieties which may have a greater potential in triggering diversification

selection criteria for models with non uniqueness abstract three objections are considered to the use of mccallum s rules for picking the minimal state set solution in rational expectations models with multiple equilibria it is shown that these difficulties can be resolved using the concept of expectational stability as a selection criterion

output effects of government purchases the theoretical analysis focuses on the distinction between temporary and permanent movements in government purchases under plausible conditions the temporary case involves an output response that is positive less than one to one with the change in government purchases and larger than that generated by an equal sized but permanent shift in purchase the equilibrium real rate of return rise in the temporary case but changes little in the permanent one defense purchases are divided empirically into permanent and temporary components by considering the role of temporary wars no temporary shifts in nondefense purchases were isolated empirical results verify an expansionary output effect for temporary purchases that exceeds that of permanent purchases the results for some other expectational hypotheses are found to be generally supportive of the theory

grassroots based rural development strategies ecuador in comparative perspective abstract international donors are providing increasing amounts of assistance to grassroots based economic initiatives in latin america and elsewhere the question is can such initiatives prosper and generate widespread improvements in living standards in the context of the prevailing neoliberal economic policy agenda the paper responds to this question from comparative latin american and east asian perspectives by analyzing how economic diversification and improved living standards were achieved in two rural parishes in highland ecuador we find that in both cases access to landownership and other assets was a critical factor in permitting small scale producers to participate in market exchange in a manner that allowed them to improve their living standards hence to the extent that neoliberal policies freeze into place the highly inequitable overall structure of asset and income distribution in ecuador and elsewhere such policies inhibit the widespread replication of the two successful cases

testing between competing models of real business cycles this paper tests a real business cycle model with efficient long term labor contracts the efficient long term contract model against a standard real business cycle model the intertemporal substitution model in the former model employment and real wages are determined by bilateral dynamic bargaining between firms and workers in the latter model employment and real wages are determined instead by the dynamic optimization of households within the competitive market framework we estimate each model using aggregate japanese data our results show that the data are consistent with the efficient long term contract model but are inconsistent with the intertemporal substitution model a business cycle phenomenon is typically found in time series data on employment and real wages according to the data of almost all developed countries employment fluctuations are considerably greater than wage fluctuations many recent economic studies have attempted to explain this phenomenon most of these studies fall into the equilibrium business cycle theory in which business cycles are the result of individual agents optimizing in a competitive environment among the most famous early examples of such a theory are the rational expectations general equilibrium models of lucas 1972 and barro 1976 which stress the role of nominal shocks in the presence of imperfect information more recently the predominant equilibrium business cycle theory has been the real business cycle model of kydland and prescott 1982 long and plosser 1983 and king and plosser 1984 which emphasizes the importance of real shocks to production technology real business cycle theory considers a model economy populated by a single infinitely lived individual with given initial resources production possibilities and tastes the representative individual chooses a preferred consumption production plan and the resulting allocation is pareto optimal the implications of real business cycle theory are thus derived from the pareto optimal equilibrium allocation as calculated from the planning problem of a social planner or representative agent a policy implication of this theory is that monetary policy has no significant effect

what has been learned about labor supply in the past twenty years the main advance in the study of labor supply in the past 20 years has come in recognizing and interpreting the variety of different labor supply functions that coexist in the empirical literature a crucial theoretical distinction with important empirical payoff is that between labor supply choices at the extensive margin i e labor force participation and employment choices and choices at the intensive margin i e choices about hours of work or weeks of work for workers another important distinction is the one between a descriptive labor supply function and a structural supply function that can be the basis for out of sample policy investigations concerning responses to tax and welfare programs and evaluations of welfare losses a full understanding of the participation hours dichotomy leads to an appreciation of the importance of the problem of selection bias what is the wage to impute to a nonworking person these distinctions are a legacy of the research conducted on labor supply over the past 20 years many important empirical questions have been addressed i how strong are the effects of taxes welfare and transfer programs on labor supply ii how important is intertemporal substitution can life cycle labor supply models explain business cycle labor supply behavior iii has the consensus view of the 1960 s of high labor supply elasticities for married women and low labor supply elasticities for married men held up all of the empirical evidence assembled on labor supply must be called into question in the light of important research on the basic quality of the data conducted by analysts at the university of michigan i discuss this evidence in a concluding section except for my discussion of measurement issues i focus only on the major discoveries about which a general consensus has emerged

staying in business abstract the paper analyses factors which help a small entrepreneurial firm to stay in business the time scale for the analysis is three years 1985 1988 the main issue that the paper is concerned with is the role of market and financial variables primary source data are used an estimated probit model indicates that for this sample product range and gearing are the key maket and financial variables respectively the greater the product range and the lower the gearing ceteris paribus the better the chances of staying in business

longitudinal analysis of relationships between planning and performance in small firms this paper investigates causal relationships between planning and performance utilizing a longitudinal database with responses from the same 2 956 businesses over a four year period results confirm the association between planning activity and performance that is evident in most extant literature they also however cast doubt on the traditional perception of the causal sequence of that association although subject to a number of limitations the results indicate that planning is more likely to be introduced into a small firm after a period of growth rather than before a period of growth these results make an important contribution to understanding the planning performance relationship for two main reasons they overcome the static data and relatively smaller sample size restrictions of many past studies and they provide evidence concerning the sequence of the relationship between planning and performance

institutional change climate risk and rural vulnerability cases from central mexico summary a multiscalar multistressor assessment of rural vulnerability is presented illustrating how globalization market liberalization and climatic risk simultaneously structure the livelihood strategies of mexican smallholders ethnographic data collected in three communities are used to argue that farmers capacities to manage climatic risk are circumscribed by the ways in which they are able to negotiate changes in agricultural policy four livelihood strategies are explored in detail to show that market integration does not necessarily improve risk management capacity and that subsistence maize production while highly sensitive to hazards may actually serve to enhance livelihood stability the dominance of economic uncertainty over environmental risk in households decision making implies a continued role for government intervention to help households adapt to climatic stress

family farm sustainability in southern brazil an application of agri environmental indicators abstract this paper investigates the sustainability of agroecological and conventional agriculture on small farms in southern brazil a methodology was developed to identify agri environmental indicators of the environmental economic and social dimensions of the farming systems the criteria used for selecting sustainability indicators were policy relevance measurability validity analytical soundness level of aggregation communication to the user based on these criteria indicators were selected for natural financial physical human and social capital assets the research identified external indicators those relevant to researcher policy makers and internal indicators those relevant to the resource users the two sets were combined and data relevant to the selected indicators were collected from secondary sources and also direct from farmers through a small scale sample survey after analysing the data indicators were selected for each capital asset to generate a multi criteria assessment of sustainability at three scales farm local and regional the analysis provided evidence of ecological and social advantages of ecological farms but financial disadvantages associated with the cost of alternative marketing arrangements for agroecological produce the paper draws conclusions about the usefulness of indicators in the assessment of farming sustainability and possibilities for wider application

intertemporal substitution and λ constant comparative statics abstract this paper characterizes intertemporal substitution along intertemporal consumption profiles a precise definition of the intertemporal elasticity of substitution is presented and compared to intertemporal analogs of the hicks allen and direct elasticities of substitution and the marginal utility of wealth or constant own price elasticity of demand in a model with perfect foresight i establish that constant comparative statics accurately characterizes intertemporal substitution if and only if lifetime utility is intertemporally additive i also demonstrate the usefulness of constant comparative statics in characterizing intertemporal substitution in models without time separability or perfect foresight

the intertemporal substitution model of labour market fluctuations an empirical analysis the paper uses two approaches to study whether aggregate fluctuations in employment and unemployment may be explained within a market clearing framework as intertemporal substitution in labour supply first log linear equations for labour supply and unemployment are estimated using a forecasting model to measure wage and price expectations second a utility function is used to derive and estimate an equation for labour supply as a function of the current real wage and consumption the influence of expected future real wages and interest rates is captured by the consumption variable the empirical results do not support the intertemporal substitution model

rural livelihood diversification in sub saharan africa a literature review abstractthis article provides a comprehensive review of the literature on the nature and evolution of rural livelihood diversification in sub saharan africa and the situation regarding smallholders it reveals mixed findings about the causes and consequences of livelihood diversification on rural smallholders adopting this strategy a lot of evidence from the literature suggests that it is relatively better off smallholders with sufficient assets who achieve successful livelihood diversification mainly by exploiting opportunities and synergies between farm and nonfarm activities because of asset constraints increase in incomes and wealth based on livelihood diversification has not yet benefitted the large majority of smallholders

rural poverty dynamics in kenya structural declines and stochastic escapes we use panel survey data and household event histories to explore patterns of rural poverty dynamics in kenya over the period 2000 2009 we find substantial mobility across poverty categories using economic transition matrices drawing on asset based approaches we distinguish stochastic from structural poverty transitions few households successfully escaped poverty through asset accumulation up to 35 of the upwardly mobile while a large proportion of households up to 66 declining into poverty experienced structural transitions using household event histories we find significant differences across structural poverty transition classes in livelihood strategies household level shocks and other factors

capitals and capabilities a framework for analyzing peasant viability rural livelihoods and poverty abstract on the basis of themes emerging in current debates on rural development in latin america this paper develops an analytical framework for analyzing rural livelihoods in terms of their sustainability and their implications for rural poverty the framework argues that our analyses of rural livelihoods need to understand them in terms of a people s access to five types of capital asset b the ways in which they combine and transform those assets in the building of livelihoods that as far as possible meet their material and their experiential needs c the ways in which people are able to expand their asset bases through engaging with other actors through relationships governed by the logics of the state market and civil society and d the ways in which they are able to deploy and enhance their capabilities both to make living more meaningful and to change the dominant rules and relationships governing the ways in which resources are controlled distributed and transformed in society particular attention is paid to the importance of social capital as an asset through which people are able to widen their access to resources and other actors

fair trade organic coffee rural livelihoods and the agrarian question southern mexican coffee families in transition summary we use a random sample of coffee producing households in southern mexico to compare opportunities associated with government subsidies and migration to the role of fair trade organic coffee in household livelihoods although land and labor returns among fair trade organic coffee growers are higher than for conventional growers differences in yields are more important than price premiums moreover investment in education and labor opportunities outside coffee dominate those in fair trade organic coffee the results highlight the value of an integrated approach to the agrarian question that improves productivity and prices and supports other pathways for improving incomes

unemployment and other measures of labor market inefficiency a comparison of u k and u s labor markets 1931 96 unemployment is probably the most widely feared phenomenon of our times it represents an enormous waste of human resources reflects an important degree of inefficiency in economic systems and causes a disturbing degree of social distress organisation for economic co operation and development oecd 1994 pp 4 6 i introduction unemployment is undoubtedly one of the most researched areas of economics determinants of the number of unemployed and duration of unemployment the role of unemployment on the depreciation of human capital and on general life satisfaction the interrelationship of unemployment and inflation and unemployment and output okun s law and policies to reduce or even eliminate unemployment are just a few of the areas of research on unemployment the underlying assumption in many studies on unemployment is that there is a very close correspondence between unemployment and labor market inefficiency as witnessed in the quote by the oecd just given although rarely if ever stated there is also the assumption that a given unemployment rate indicates similar levels of inefficiency either across time and or regions or countries unfortunately and somewhat surprisingly this assumption has not been tested thus far 1 given the importance of comparisons of unemployment on the direction of macroeconomic policy of governments it is very important to determine whether unemployment is indeed a good proxy for labor market inefficiency the goal of the article therefore is to examine this issue thus we pose the following key questions 1 to what degree do unemployment rates reflect labor market efficiencies 2 if the goal is to measure relative labor market inefficiency is it meaningful to compare unemployment rates over time and 3 to what degree do differences in unemployment rates across countries reflect differences in labor market inefficiencies basic economic theory shows that inefficiency in any market depends not only on the wedge between supply and demand but also on the elasticities of demand and supply the calculation of so called harberger triangles harberger 1954 of deadweight loss dwl which has a long history in the industrial organization and public finance literatures indicates that for a given wedge between supply and demand the dwl can be very different depending on the elasticities of supply and demand interestingly however studies examining the costs of unemployment do not focus on this basic view of welfare loss studies such as gordon 1973 ahsenfelter 1980 hurd 1980 clark and oswald 1994 murphy and topel 1997 and leslie and blackaby 1999 among others examine the costs of unemployment from an individual perspective but do not measure inefficiency from a market perspective which is the focus of the harberger triangles except for a publication by fortin and bernier 1988 2 we know of no other application of calculating harberger triangles to determine the level of inefficiency in the labor market therefore this article uses labor market data from 1931 to 1996 in the united states and united kingdom to calculate the dwl of unemployment and then compares the estimates of dwl to the unemployment rate to determine how closely related inefficiency and unemployment are 3 the following section investigates the theoretical relationships between unemployment labor supply and demand elasticities and dwl from this discussion we propose two alternative measures of inefficiency the first is the unemployment loss index dwl divided by gross domestic product gdp which indicates how large labor market inefficiency is relative to total output in the economy the second measure is dwl per unemployed person a measure of the potential average gains to employing an unemployed individual section iii outlines the data and methodology used to estimate the elasticities of labor supply and labor demand over time in the united states and united kingdom allowing for changes in the elasticities over time

on non uniqueness in rational expectations models an attempt at perspective abstract many macroeconomic models involving rational expectations give rise to an infinity of solution paths even when the models are linear in all variables some writers have suggested that this non uniqueness constitutes a serious weakness for the rational expectations hypothesis one purpose of the present paper is to argue that the non uniqueness in question is not properly attributable to the rationality hypothesis but instead is a general feature of dynamic models involving expectations it is also argued that there typically exists in a very wide class of linear rational expectations models a single solution that excludes bubble or bootstrap effects one that occur only because they are arbitrarily expected to occur a systematic procedure for obtaining solutions free from such effects is introduced and discussed in addition this procedure is used to interpret and reconsider several prominent examples with solution multiplicities including ones developed by fischer black and john b taylor

a quantitative content analysis of the characteristics of rapid growth firms and their founders a group of firms that is attracting attention are rapid growth firms these firms are of particular interest because rapid growth is an indication of market acceptance and firm success by studying rapidgrowth firms researchers can help all firms better understand the attributes associated with firm growth despite these positive outcomes however rapid firm growth is difficult to achieve and maintain this study adds to the literature through a quantitative content analysis of the narrative descriptions of 50 rapid growth firms and a comparison group of 50 slow growth companies the purpose of the study was to draw from the narratives a list of empirically grounded growth related attributes that are associated with rapid growth firms the findings of the study resulted in the advancement of a conceptual model of the attributes of rapid growth firms in four areas founder characteristics firm attributes business practices and human resource management hrm practices

on testing the intertemporal substitution theory of labor supply many empirical tests of the intertemporal substitution theory of labor market fluctuations have assumed that shocks to the labor demand curve are the sole source of variance in hours and wages we show that conclusions based on these tests are very sensitive to small deviations from this extreme case using data generated by a standard real business cycle model we show that standard methods incorrectly reject the intertemporal substitution theory even when demand curve shocks account for over 90 of the variance in wages and hours

engendering social capital women workers and rural urban networks in indonesia s crisis recent approaches to social capital have cautioned against the view that social networks are resources to be called upon in times of crisis we contribute a feminist perspective to this argument and call attention to the gendered power relations of social capital and social networks we draw on field studies that examine women migrants rural urban networks in two regions of indonesia during the 1997 99 economic crisis period our findings direct attention toward the gender specific limitations of social capital as a resource for development and identify some ways in which the costs and benefits of social capital are organized by gender

available capital utilized capital and shadow prices in inclusive wealth accounting abstract previously accounting for comprehensive or inclusive wealth has focused on the supply side of capital assets however human well being created by capital assets inherently depends on the demand side as well in particular if capital is not utilized at its full capacity then realized or actual human well being may be less affected by available capital than by effective or utilized capital in principle this notion is embodied in a shadow price which is defined as the marginal contribution of capital assets to social well being the shadow price becomes higher if the underlying resource allocation mechanism improves in practice one can account for such underutilization by adjusting shadow prices to reflect only the utilized quantity of the capital in question furthermore capital utilization has different nuanced implications for produced human and natural capital and its implications even vary across some classes of natural capital within this line of theoretical thought we provide empirical estimates of the changes in inclusive wealth and sustainability of selected developing countries in recent years by comparing available and utilized capital assets we find that sustainability assessments may be revised based on utilized capital due to among others human capital underemployment and non renewable natural capital accessibility

does more mean worse three decades of enterprise policy in the tees valley this paper argues that there have been three distinct phases of enterprise policy in the uk in the past 30 years the 1970s saw no effective enterprise policy policy off the 1980s witnessed an attempt to increase the number of start ups and the 1990s saw a concentration on business quality this paper looks at how enterprise has evolved in cleveland tees valley over the past three decades it suggests and finds that businesses in the 1980s were more numerous but of lower quality even if the influence of unemployment is accounted for than those from the 1970s and 1990s this implies that we should be cautious about the value of policy attempts to increase business formation rates in areas such as cleveland tees valley

serious games in livelihood analysis reflections from the case of agricultural wage labourers in andhra pradesh abstract this article presents an approach to anticipating future livelihood portfolios through sherry ortner s model of serious games the value of the model is to draw attention to the always shifting purposes and intentions that direct people s lives within a social cultural and material context that differentially constrains and enables power is central to the approach and to the understanding of processes of social reproduction and transformation i use the model of serious games to examine the proposition that agricultural labour will become less important in the diverse livelihood portfolios of the rural poor in telangana region andhra pradesh india

trust in a rent seeking world health and government transformed in northeast brazil abstract this article draws lessons from a set of innovative programs carried out by a state government in brazil now widely acclaimed for excellence in public management key to the high performance was strong worker commitment to the job and what the state did to elicit a topic of little note in the development literature but of central importance in the literature of industrial performance and workplace transformation in the industrialized countries the state created an unusual sense of calling among the program s workers new prestige in the communities where they worked and an informed citizenry that both monitored the workers and trusted them

environmental entitlements dynamics and institutions in community based natural resource management abstract while community based natural resource management cbnrm now attracts widespread international attention its practical implementation frequently falls short of expectations this paper contributes to emerging critiques by focusing on the implications of intracommunity dynamics and ecological heterogeneity it builds a conceptual framework highlighting the central role of institutions regularized patterns of behavior between individuals and groups in society in mediating environment society relationships grounded in an extended form of entitlements analysis the framework explores how differently positioned social actors command environmental goods and services that are instrumental to their well being further insights are drawn from analyses of social difference new dynamic ecology new institutional economics structuration theory and landscape history the theoretical argument is illustrated with case material from india south africa and ghana

can a real business cycle model pass the watson test abstract watson 1993 measures of fit for calibrated models journal of political economy 101 6 1011 1041 proposes a procedure for evaluating the fit of a dynamic equilibrium business cycle model under watson s criterion the standard real business cycle rbc model fails dramatically in reconciling the dynamics of the model with the data this inability to account for the dynamics of us aggregate data remains a major challenge to rbc theory this paper demonstrates that reasonable modifications can bring rbc theory into closer conformity with the data the empirical results indicate that when habit formation on leisure choice and employment externality are incorporated into the analysis the striking spectral density differentials documented by watson virtually vanish at business cycle frequencies

shadow prices of social capital in rural india a nonparametric approach this article studies the role of social capital on cotton production efficiency and productivity for a sample of small farms in maharashtra india using data envelopment analysis input shadow prices are computed as an indicator of the importance of social capital relative to other inputs results suggest social capital to be the input with the highest contribution to production efficiency after land the luenberger indicator is used to assess the productivity improvement associated to an investment in social capital which is found to be on the order of 12 undertaking collective production activities is found to play an important role in improving productivity this is especially relevant to agricultural households facing important economic and institutional restrictions that make it difficult to increase conventional expensive inputs

the forward method as a solution refinement in rational expectations models this paper generalizes the standard forward method of recursive substitution to a general class of linear rational expectations models with potentially multiple fundamental solutions we propose a key property embedded in the forward solution the no bubble condition as an economically sensible solution renement in the class of fundamental solutions in the literature the no bubble condition has been assumed to rule out non fundamental bubble solutions however since the condition involves expectations of the future endogenous variables it must be veried for every rational expectations equilibrium we show that the forward solution is the only fundamental solution satisfying the no bubble condition and that it is hard to justify economically fundamental solutions violating this condition we provide several economic examples where the fundamental solutions obtained by other solution methods and rened by other solution selection criteria violate

trajectories of small business financial structure a dynamic theory of the small firm is expounded assuming entrepreneurs maximise business value over a finite time horizon predicted trajectories for key financial variables are seen to depend on whether debt or equity are cheaper the predicted trajectories are compared with actual trajectories using empirical evidence from three years of detailed primary source data on one hundred and fifty new business startups in scotland evidence largely confirms predictions of the model for the cheap equity case for this case as capital and sales rise steadily debt is retired rapidly except when interest rates on long term debt are low this finding is supported by explicit empirical trajectories of key financial variables

on gradual disinflation the real exchange rate and the current account abstract we study the effects of a credible gradual exchange rate based disinflation program in a two sector economy after an initial exchange rate depreciation the reductions in the rate of devaluation reduce the monetary wedge generated by the cash in advance constraint leading to a gradual increase in absorption that yields progressive real exchange rate appreciations and current account deficits an initial boom in economic activity is not followed by a later contraction as labour supply expands during the whole length of the program many of the model s predictions are in accordance with the stylized facts on disinflation in chronic inflation countries in particular those of the mexican program of 1988 1992

avoiding the resource curse indigenous communities and canada s oil sands summary concerns about a resource curse in canada have been raised in response to rapid growth in the petroleum sector in northern alberta in previous research there has been little consideration of how symptoms of the resource curse are experienced and managed at a regional scale and by indigenous communities an analysis of effects and responses is offered using a natural financial human and social capitals framework without consideration of how to manage the symptoms of the resource curse oil and gas activity is likely to further disadvantage indigenous populations already living on the margins of canadian society

contesting legitimacy of voluntary sustainability certification schemes valuation languages and power asymmetries in the roundtable on sustainable palm oil in colombia voluntary certification schemes aimed at assuring producer compliance with a set of sustainability criteria have emerged as market based instruments mbis of sustainability governance however the impacts they tackle can be part of a complex arena of socio environmental conflict where values and powers of business and local actors compete legitimacy of these schemes not only results from compliance by business actors but also depends on acceptance by local actors affected by or resisting the industries that these mechanisms aim to govern this paper explores the influence of different local actors values and powers on legitimacy granting or contestation by local actors during national processes of sustainability criteria development we analyse the case of the roundtable on sustainable palm oil rspo in colombia using an approach that combines concepts of ecological economics and political ecology with the legitimacy literature based on critical sociology in colombia the palm oil industry led the initiative to implement certification under national interpretation of rspo principles and criteria however the national interpretation process revealed power asymmetries among stakeholders and clashes between their different values this resulted in strong contestation of rspo legitimacy by local actors who resist expansion of oil palm cultivation

local capacity village governance and the political economy of rural development in indonesia summary this paper develops a framework for conceptualizing local capacity to address village level livelihood and governance problems the framework is based on an analysis of asset distribution combined with an explicit analysis of the links between processes of state formation state business linkages and local forms of social capital the framework is used to discuss findings from recent research on village capacity in rural indonesia the discussion suggests that it is possible to link a political economic approach to rural development with recent conceptualizations of social capital such an analysis can illuminate the forms taken by and the effectiveness of village level collective action in ways that either purely political economy or social capital approaches do not

what makes a new business start up successful this paper seeks a good measure of new business performance and then explains this measure by various dimensions of business strategy three criteria are used to create a one dimensional ordinal ranking of high medium and low performance for new business starts employment growth return on capital employed and labour productivity it is shown that statistical cluster analysis provides a convincing separation of a sample of new business starts into high medium and low performance categories using a minimum distance criterion for clustering an ordinal logit model with selection is then used to explain this performance ranking the results indicate that many widely discussed features of small business strategy have little or even negative impact on performance of the numerous aims that owner managers may adopt survival growth etc only one appears to have a major impact on performance the pursuit of the highest rate of return on investment many entrepreneurial perceptions of their own capabilities appear false or unimportant with the exception of organisational features and systems

the dynamics of welfare gains and losses an african case study this article uses panel survey data for cote d ivoire to investigate the determinants of welfare gains and losses of households over time a first difference model is estimated which takes account of initial conditions for urban areas it was found that human capital is not only a key explanatory factor for levels of welfare but also the most important endowment to explain welfare changes over time in rural areas physical capital especially land and farm equipment mattered most household size and composition and socioeconomic characteristics of the household also affected welfare changes policy implications are discussed

smallholder livelihood adaptation in the context of neoliberal policy reforms a case of maize farmers in southern veracruz mexico governments around the world have embraced trade liberalisation as a means of enhancing efficiency to realise economic growth and alleviate poverty likewise the mexican government implemented neoliberal policy reforms the nafta in particular to stimulate sustainable development using the mexican maize sector as illustration this article describes the adaptation process of smallholders to market changes shaped by these reforms going beyond the aggregated level we have investigated smallholders livelihood strategies contrary to what economic models estimated our data suggests that farmers intensified the cultivation of maize rather than switch to sectors in which mexico has a comparative advantage

sustainability as it pertains to minerals and energy supply and demand a new interpretative perspective for assessing progress this paper addresses the pressing research gap that demands an overarching framework to assess the progress of mining minerals and energy supply and demand networks towards sustainable development the framework proposes a hierarchy from sustainable development which begins at the global scale to operating sustainably which begins at the level of unit operations the two concepts overlap in the middle with a focus upon regional economies guidance is provided to assess the performance of both dynamic dimensions sustainable development is assessed in terms of equity and operating sustainably is assessed in terms of the changing states of maturity of the activities being monitored the papers from this special volume were the input sample to assess the extent to which these performance dimensions were being addressed in analysing the progress towards sustainable development it was found that papers were mainly focussed on equity within supply countries but they provided little attention to the other three equity conditions proposed demand met at a reasonable price future needs met and profitable transfer agents the transition towards operating sustainably was promising with results that revealed progress along the proposed four stage maturity journey which includes 1 solely profit maximising 2 efficiency focussed 3 integrating by connecting and 4 adaptable resilient a comprehensive definition for operating sustainably is proposed for discussion and refinement it is suggested that the definition proposed can be used for selecting appropriate indicators for measuring and documenting progress

the duhem quine thesis lakatos and the appraisal of theories in macroeconomics the point of this paper is to outline the implications of the duhem quine thesis for the task of appraising theories in economics the duhem quine thesis dqfrom now on states that it is not possible to falsify single hypotheses because it is invariably conjunctions of hypotheses which are being tested thus if a particular hypothesis is found to be in conflict with some piece of empirical evidence all that we can say is that the conjunction of the particular hypothesis with a set of auxiliary hypotheses is false we can never be sure that it is not one or more of the auxiliary hypotheses which is responsible for the anomalous empirical evidence rather than the particular hypothesis in which we are most interested expressed in symbols this means that arguments of the form ho 0 0 ho are not justified where ho is a particular hypothesis o is the observational evidence and the symbols and mean imply conjoined with and not instead our arguments can only justifiably be phrased in the form g1 0 0 g1 where g1 is a conjunction of hypotheses which contains ho there could well be some different conjunction of hypotheses gn which contains ho which is consistent with the empirical evidence the contention of this paper is that many of the debates in macroeconomics have been misguided in that the jointness of hypothesis testing has been ignored by participants in the debates instead the focus of attention has been on the appraisal of single target hypotheses considered in isolation from supportive auxiliary hypotheses the implicit assumption being that it is possible to falsify single target hypotheses the latter assumption is wrong following the logic of the dq thesis we are obliged to conduct our appraisal at the level of groupings of hypotheses that is to appraise any target hypothesis in conjunction with its supportive auxiliary hypotheses the implications of this line of reasoning are perhaps best unravelled in the context of concrete examples from debates in macroeconomics over the last two decades before moving to this task we will in section i provide a brief outline of the history of the dq thesis section ii will then illustrate the misguidedness of appraising target hypotheses in isolation from their supportive auxiliary hypotheses with reference to the often heated and continuing debate regarding the stability of the demand for money function the question of how to appraise groupings of hypotheses is considered in section iii here we will centre the

flows funds and the complexity of deprivation using concepts from ecological economics for the study of poverty abstract poverty has been increasingly conceptualized as being multidimensional involving deprivation in many dimensions of life this paper discusses issues and implications of multidimensional poverty by adopting concepts commonly used in ecological economics in particular poverty is approached as an irreducible complex phenomenon for which many legitimate but non equivalent descriptions exist issues of social and technical incommensurability are illustrated for different meanings and measurement types of poverty georgescu roegen s flow fund framework is interpreted informed by the capability approach of amartya sen the paper argues that a predominant focus on flows as a proxy to analyze poverty represents rather a short term perspective on access to satisfiers to fulfill particular needs contrary to that focusing on valued funds may provide useful information for the analysis of capabilities that persons and societies might pursue in the long term furthermore it is argued that strong poverty alleviation needs to adopt analytical tools that can deal with non trade off cases improvements in one poverty dimension cannot always compensate for the deterioration of other poverties this implies to rethink the usefulness of aggregate multidimensional poverty indices as well as the predominant use of income measures

new estimates of intertemporal substitution abstract this paper estimates the intertemporal elasticity of substitution for married males taking into account that many individuals are at a corner solution for weeks worked by virtue of working year round the fact that these individuals do not choose to engage in much intertemporal substitution may simply indicate that the corner solution inhibits their ability to do so rather than indicating a low desire to intertemporally substitute our estimates are able to distinguish between these two cases with the results showing much higher intertemporal elasticities of substitution than reported in earlier studies

ten years of q squared implications for understanding and explaining poverty summary over the past decade there have been a number of initiatives to promote a more systematic integration of quantitative and qualitative or q squared approaches to poverty analysis in the global south and a large body of literature had emerged the objective of the article is to present a selective review of this empirical work with a view to demonstrate the value it has added for understanding and explaining poverty the evidence strongly suggests that q squared approaches have aided our understanding of the characteristics of the poor and the causes of poverty

trust membership in groups and household welfare evidence from kwazulu natal south africa unfortunately these two literatures have remained largely unconnected the group and network literature concludes that participation has important economic benefits even when the stated function of the group is noneconomic in most cases however the mechanisms by which groups and networks achieve this are unclear the determinants of trust and participation in groups literature highlights the importance of income and social homogeneity what remains less understood is whether and how trust can be generated for example via participation in groups this article links the empirical literatures referenced above by exploring the relationship between membership in groups and trust specifically using longitudinal data from kwazulu natal province south africa we examine 1 the importance of trust in the decision to join groups 2 the subsequent ability of groups to generate trust and 3 the effect of group membership and trust on a measure of well being per capita household income in addition we disaggregate groups into financial and nonfinancial and we categorize trust in people by agent or actor therefore we can explore whether trust in different kinds of actors is important for participation in different kinds of groups and whether participation in different kinds of groups is important for generating trust in different kinds of actors excerpt

the significance of diversification for rural livelihood systems abstract there is an increasing awareness that diversification plays a strategic role in rural livelihood systems the principal question to be addressed in this paper pertains to the conditions and the ways in which rural households diversify their livelihood activities and strategies to answer this question empirical evidence will be reviewed specific attention will be paid to perspectives that may shed new light on the issue of rural livelihood diversification a gender perspective a temporal perspective and the hiv aids lens in the paper the livelihood system is seen as an open system interfacing with other systems and using various resources and assets to produce livelihood with the household as the locus of livelihood generation diversification is defined as the process by which households construct increasingly diverse livelihood portfolios making use of increasingly diverse combinations of resources and assets

exploring the determinants of on farm transitions evidence from rural china to shed light on the sustainable development of rural areas we study the determinants of transitions from subsistence farming into either formal agricultural employment or agricultural entrepreneu

editorial human capital and human capability i would like to comment on the connection as well as contrast between two distinct but related areas of investigation in understanding the processes of economic and social development the accumulation of human capital and the expansion of human capability the former concentrates on the agency of human beings through skill and knowledge as well as effort in augmenting production possibilities the latter focuses on the ability of human beings to lead lives they have reason to value and to enhance the substantive choices they have the two perspectives cannot but be related since both are concerned with the role of human beings and in particular with the actual abilities that they achieve and acquire given her personal characteristics social background economic circumstances etc a person has the ability to do or be certain things that she has reason to value the reason for valuation can be direct the functioning involved may directly enrich her life such as being well nourished or being healthy or indirect the functioning involved may contribute to further production or command a price in the market the human capital perspective can in principle be defined very broadly to cover both types of valuation but it is typically defined by convention primarily in terms of indirect value human qualities that can be employed as capital in production in the way physical capital is in this sense the narrower view of human capital approach fits into the more inclusive perspective of human capability which can cover both direct and indirect consequences of human abilities consider an example if education makes a person more efficient in commodity production then this is clearly an enhancement of human capital this can add to the value of production in the economy and also to the income of the person who has been educated but even with the same level of income a person may benefit from education in reading communicating arguing in being able to choose in a more informed way in being taken more seriously by others and so on the benefits of education thus exceeds its role as human capital in commodity production the broader human capability perspective would record and value these additional roles the two perspectives are thus closely related but distinct the significant transformation that has occurred in recent years in giving greater recognition to the role of human capital is helpful for understanding the relevance of the capability perspective if a person can become more productive in making commodities through better education better health and so on it is not unnatural to expect that she can also directly achieve more and have the freedom to achieve more in leading her life both perspectives put humanity at the center of attention altogether this involves to a great extent a return to an integrated approach to economic and social development championed particularly by adam smith both in the wealth of nations and in the theory of moral sentiments in analysing the determination of production possibilities smith emphasized the role education as well as division of labor learning by doing and skill formation the development of human capability in leading a worthwhile life as well as in being more productive is quite central to smith s analysis of the wealth of nations indeed adam smith s belief in the power of education and learning was peculiarly strong regarding the debate that continues today on the respective roles of nature and nurture smith was an uncompromising nurturist and this fitted in with his massive confidence in the improvability of human capabilities

household strategies and rural livelihood diversification this article reviews the recent literature on diversification as a livelihood strategy of rural households in developing countries with particular reference to sub saharan africa livelihood diversification is defined as the process by which rural families construct a diverse portfolio of activities and social support capabilities in order to survive and to improve their standards of living the determinants and effects of diversification in the areas of poverty income distribution farm output and gender are examined some policy inferences are summarised the conclusion is reached that removal of constraints to and expansion of opportunities for diversification are desirable policy objectives because they give individuals and households more capabilities to improve livelihood security and to raise living standards

do more heavily regulated economies have poorer performing new ventures evidence from britain and spain we test two alternative perspectives on the start up size and subsequent growth of new firms in a heavily regulated hr economy and a lightly regulated lr economy the first argues that in an hr economy there will be fewer new firms and those that do start will be larger than those in an lr economy but they will grow more slowly a second perspective is that regulation does not influence the scale of entrepreneurship merely its distribution between that which is registered and that which is not registered using parallel datasets for hr spain and lr britain we find some support for both perspectives specifically we find that registered new firms in britain do start smaller than in spain and do grow faster however when both registered and unregistered firms are included these differences disappear

intertemporal substitution in macroeconomics consumption labor supply and money demand this paper introduces money into the consumption leisure based intertemporal substitution model the optimization problem poses that the household chooses consumption labor supply money demand and wealth holdings of real money balances along with consumption and leisure determine utility the constant decomposes wealth into money and an alternative asset the authors estimate the derived semireduced form equations using per capita u s data the findings indicate significant interest rate intertemporal substitution in labor supply but weak effects in consumption and money demand the empirical evidence supports contemporaneous nonseparability of consumption money and leisure within a well behaved underlying utility function copyright 1992 by mit press

the indeterminacy of prices under interest rate pegging the non ricardian case abstract this paper investigates the issue of price level indeterminacy under a pure interest rate peg in models that depart from standard ricardian assumptions using a monetary version of blanchard s finite horizons model i find wealth effects operating on government bonds are not sufficient to determine a unique price level next i consider price determination under a non ricardian fiscal authority i show that if agents rationally perceive the possibility of fiscal default the price level is again indeterminate i conclude that departures from ricardian equivalence are not sufficient to ensure a unique price level under a monetary policy of pure interest rate pegging

backward and forward solutions for economies with rational expectations in models where anticipations of future endogenous variables influence current behavior there exists an infinity of solutions under the assumption of rational expectations this problem has been dealt with in the study of macro economic models by the implicit or explicit use of one of three additional requirements optimality consistency with alleged economic behavior or conformity of the endogenous variables to an imposed stationarity condition these requirements have coincided in existing models leading to the choice of a unique solution a forward solution the purpose of this paper is to review the problem characterize the solutions and examine whether these requirements are acceptable section i presents a simple model and derives the set of solutions the model makes no claim to generality but has the major advantage that the issues are easily understood in this simple case section ii discusses the requirement of consistency with economic behavior section iii discusses the requirement of stationarity and section iv provides some conclusions
