risk private information and the family in the last fifteen years our understanding of the behavior of households in both highand low income countries has increased significantly econometric studies contributing to this body of knowledge concerned with the determinants of such behavior as labor supply fertility health and food consumption however have generally taken the structure of the household as exogenously given while some progress has been made concerning how changes in the legal structure alter patterns of family formation and breakup the wide variety of family organizations observed across countries of the world or the evolution of family structure within countries cannot be readily explained by existing models while some economists have suggested that organizations based on kinship can be understood in terms of transaction economies yoram ben porath 1980 robert pollak 1985 there are now few precise implications of this approach and little or no evidence of its usefulness for predicting or explaining the existence of any particular family structure in specific settings characterized by their natural endowments and or legal structure in this paper i discuss some recent studies of family and household organization in one specific context rural india that have sought to formulate a model of household structure based on the need for individuals in lowincome private information settings to protect themselves against intertemporal fluctuations in resources arising from the natural vagaries of water supply i also present some new evidence on the relationship between family arrangements and measured risk characteristics of the agricultural environment in these settings while many economists have highlighted risk and information consideration in the study of such formal rural institutions as sharecropping permanent servitude and contractual interlinking studies of these individual contractural arrangements have ignored the family itself as a risk mitigating institution moreover much of this literature has been solely concerned with ex ante measures to reduce risk contractual instruments or production factors that reduce the effects of variability in the exogenous production input rainfall on income mechanisms serving to preserve consumption stability ex post in the face of variability in realized income have been neglected

specific experience household structure and intergenerational transfers farm family land and labor arrangements in developing countries data from indian rural household survey was used to test th hypothesis that the coexistence in traditional rural societies of extended intergenerational families infrequent land sales and high reliance on family members as farm laborers is the result of the economic advantages which accrue from the knowledge gained by farming a particular ploy of land over a long period of time the land specific experience of elderly members of a intergenerational household who farmed the land as a child and then as an adult are expecially critical in adverse weather years most previous investigators attributed the existence of multigenerational households the use of family members rather than hired laboreds and the infrequency of land sales to deficiencies in the market i e labor market imperfections and an absence of capital insurance and asset markets in the present investigations these same characteristics are viewed as having an economic advantages a model for estimating the contribution of the experience of the elderly household members to agricultural profits was developed and applied to data from a 3 year panel study of 2900 indian rural farm households the data was collected between 1968 71 by the national council of applied economic research the survey collected information on farm profits farm inputs demographic characteristics and the effects of weather conditions on profits a major limitation of the study was a lack of information on the duration of land ownership age of household members was substituted as a proxy for duration of ownership findings were consistent withe the hypothesis in poor agricultural years gross returns for households which contained an elderly household member were greater than the gross returns for comparable households which did not contain an elderly member the economic advantages of specific knowledge embodied in the experienced elderly farmer were comparable to the economic advantages which accrued to households whose members were more educated the hypothesis cannot fully explain the existence of intergenerational families since there is a relatively large proportion of such families among nonfarm families in many countries including india findings suggest that intergenerational families may provide for more occupational diversity and thereby reduce income risks the specific experience hypothesis has policy implications if technological changes are introduced the value of specific experience may be lost and the frequency of intergenerational households may decline the hypothesis may also explain why farmers are reluctant to agree to land redistribution and consolidation schemes this reluctance may disappear after sufficient technological change has occurred

environment technology and the social articulation of risk in west african agriculture two preoccupations are not mutually exclusive superficially they share the common concern that liberalization is insufficient to resolve the subsaharan food crisis at a deeper level the two preoccupations are more intimately interrelated via the correspondence that links initial wealth to risk exposure and to behavior in both production and asset accumulation a number of recent empirical studies of risk in low income countries find that households are able to employ their accumulated assets to smooth consumption in the face of adverse agricultural production shocks 3 missing from these studies is explicit attention to the fact that the effective risk from which households insulate consumption is not that of production shocks directly but of those shocks as socially articulated by institutions and property rights this article explores the creation and distribution of effective risk estimating how environment technology and social factors interact to construct it endogenously 4 put differently this article develops the notion that the risk from which households ex post try to insulate consumption is not an immutable natural or technical feature of the landscape as michael watt s contrast between precolonial and colonial nigeria forcefully demonstrates the effective risk presented by an unchanged set of environmental and technical circumstances can

financial intermediation and endogenous growth an endogenous growth model with multiple assets is developed agents who face random future liquidity needs accumulate capital and a liquid but unproductive asset the effects of introducing financial intermediation into this environment are considered conditions are provided under which the introduction of intermediaries shifts the composition of savings toward capital causing intermediation to be growth promoting in addition intermediaries generally reduce socially unnecessary capital liquidation again tending to promote growth

interest profits and suboptimality in a demand constrained macro model keynes argues that under pessimistic expectations investment demand falls short of full employment savings consequently income adjusts to bring savings into line with investment resulting in unemployment and or excess capacity classical theory as reconstituted in postwar textbooks counters that investment and full employment savings are equilibrated by adjustment of the interest rate thus current output will obtain its optimal level at full employment and full capacity despite pessimistic expectations of future demand the only way this can fail is if some type of wage or price rigidity prevents the stock of real money balances from accommodating the demand for them at the fullemployment interest rate fig i illustrates the keynesian and classical views in a traditional loanable funds diagram here the full employment supply of savingsis given by s investment demand under optimistic expectations is i and the full employment interest factor unity plus the interest rate is r pessimistic expectations shift investment demand to it reducing the full employment interest factor to r in the classical model or reducing employment income and hence savings to s in the simplest keynesian model general equilibrium theory provides a third view on interest rate determination here competition over prospective profits leads the interest rate to adjust to the return on capital adjusted for risk so prospective profits are eliminated provided capital is mobile to reconcile this view with either the keynesian or classical view depicted in fig i it should first be noted that the general equilibrium model of interest rates is a multi period model while the textbook models of fig i are not they are one period models with views of the future imprecisely summarised in the investment demand function furthermore in those models views of the future are not analysed for prospective profits or their consequences graphically the inframarginal triangle between the investment demand curve and the interest rate line is not analysed or explained how can such prospective profits survive competitive activities the present paper proposes to examine this issue in as simple a model as possible the key simplifications are as follows first the simplest multi period

a disequilibrium model with smooth regime transitions and a keynesian spillover for switzerland s labor market abstract this paper presents a disequilibrium labor market model in which aggregation over a continuum of micro markets with different demand supply ratios produces smooth macro relationships mapping aggregate demand and supply onto actual employment and regime proportions aggregate labor demand consists of a classical part derived on a putty clay assumption and a keynesian spillover from the goods market the specification of labor supply incorporates intertemporal substitution the degree of aggregate imbalances on labor and goods markets is measured by business survey data the estimated model indicates a growing mismatch between the micro structures of demand and supply of labor the short run fluctuations of employment are primarily traced back to the keynesian spillover classical determinants of labor demand are relevant as well but only in the medium term labor supply is rather inert and thus absorbs the swings of labor demand only partly

credit markets in northern nigeria credit as insurance in a rural economy this article addresses the issues of imcomplete markets and imperfect information in the context of credit markets in rural northern nigeria in much recent theoretical literature the problems of moral hazard and adverse selection are assumed to be decisive for the organization of agrarian institutions in contrast it is found that in the four villages surveyed credit transactions take advantage of the free flow of information within rural communities information asymmetries between borrower and lender are unimportant and their institutional consequences the use of collateral and interlinked contracts are absent credit transactions play a direct role in pooling risk between households through the use of contracts in which the repayment owed by the borrower depends on the realization of random production shocks by both the borrower and the lender

costly monitoring financial intermediation and equilibrium credit rationing abstract this paper establishes a link between equilibrium credit rationing and financial intermediation in a model with asymmetrically informed lenders and borrowers costly monitoring and investment project indivisibilities intermediation is shown to dominate borrowing and lending between individuals and these financial intermediaries exhibit several of the important features of intermediaries as we know them equilibrium interest rates and the aggregate quantity of loans respond quite differently to changes in taste and technology parameters depending on whether or not there is rationing in equilibrium

risk and insurance in a rural credit market an empirical investigation in northern nigeria credit contracts play a direct role in pooling risk between households in northern nigeria repayments owed by borrowers depend on realizations of random shocks by both borrowers and lenders the paper develops two models of state contingent loans the first is a competitive equilibrium in perfectly enforceable contracts the second permits imperfect information and equilibrium default estimates of both models indicate that quantitatively important state contingent payments are embedded in these loan transactions but that a fully efficient risk pooling equilibrium is not achieved the research is based on a year long survey in zaria nigeria conducted by the author

saving and growth evidence from micro data abstract this paper examines whether the observed cross country correlation between aggregate saving rates and economic growth can be explained by models in which higher growth increases saving rates rather than the other way around there are two explanations why higher growth might increase saving first life cycle theory implies that higher growth will increase the life time wealth of younger savers relative to older dissavers thereby increasing the aggregate saving rate second models of consumption with habit formation imply that consumption responds slowly to unexpected income growth so unanticipated growth can produce a higher saving rate at least in the short run i assess these explanations using time series of cross sections of household surveys from four countries the us britain taiwan and thailand i find evidence that higher growth will produce only small increases in aggregate saving rates

the desire for land strategic lending with adverse selection abstract this paper deals with a setting in which borrowers and lenders place different values on an asset that can be used as collateral under adverse selection lenders may rationally choose credit contracts with the object of attracting a relatively risky group of clients so raising their chances of gaining possession of the asset through default contracts of differing attractiveness to borrowers can also coexist in equilibrium when an inside and an outside lender compete the latter placing a lower value on the collateral and their loanable funds are sufficiently limited a separating equilibrium may exist in which the insider offers a contract which attracts risky borrowers whereas the outsider s contract is aimed at a safer group if loanable funds are ample the only equilibrium will involve pooling contracts but the insider may still offer more attractive contracts in an entry game

saving and economic shocks in rural pakistan abstract this paper adapts the recent methodology of paxson to study saving rates in rural pakistan particular attention is paid to differences in marginal rates of financial and physical saving and how these vary across income groups and by direction of income shocks households exhibit more difficulty in smoothing consumption after successive shocks than with a single shock the study also observes marginal rates of saving out of international remittances and lump sum pensions unlike domestic remittances international remittances appear to be treated much as transitory income shocks

remaining puzzles and neglected issues in macroeconomics this paper analyses the chain of transmission mechanisms of economic policy actions to financial markets output and employment and finally unemployment in an attempt to identify remaining puzzles and neglected issues in macroeconomics the paper emphasizes the consequences of fiscal and monetary policy actions on real variables including real interest rates and real exchange rates an attempt is made to explain why product demand shocks often tend to have faster effects on output and employment than on prices the paper also discusses why demand induced increases in output and employment are not systematically connected with a reduction in the product wage rate the paper ends with a discussion of various supply side considerations in macroeconomics

market power and unemployment abstract this paper explores the under consumptionist idea that market power can preclude the existence of a full employment equilibrium within the framework of the modern theory of economic growth it is shown that the introduction of market power can indeed eliminate the full employment equilibrium in an attempt to assess the importance of this possibility maximum values for the market power parameters consistent with a full employment equilibrium existing are computed in some plausible cases these maxima are uncomfortably low suggesting that market power has significant potential for causing unemployment

multidimensional poverty in crisis lessons from zimbabwe abstractzimbabwe experienced an acute social political and economic crisis from 2001 to 2008 and is now on a recovery path this paper explores changes in poverty between 2001 2007 and 2011 2012 using an alkire foster multidimensional poverty index results indicate a large increase in poverty across multiple dimensions of household wellbeing between 2001 and 2007 the start of the crisis peak followed by a decrease in poverty between 2007 and 2011 2012 during the recovery period decomposition of the index shows significantly different trends in poverty dimensions over time with implications for short and long term social assistance policies

motivations to remit evidence from botswana in this article a theory of motivations to send remittances is described and tested with data from botswana altruism is one of the motivations tested and found to be an insufficient explanation for remittances among migrants in botswana a refinement of the model stipulates a modified altruism or enlightened self interest in this model the relationship between the migrant and family is tempered by an implicit understanding of mutual benefit the household strategy may be to encourage some members to migrate as a means of spreading risk and sharing gains the household strategy is similar to an insurance policy where migration is to places where market potential is high the risks incurred might be high the example is given of migration during a drought in botswana migrant remittances were greater in households with more cattle or households with more to lose drought alone was not statistically related to remittances increases in remittances were related to increased levels of education it is suggested that repayment was the motive for parents investment in migrants education migrants gains are identified as the potential for an inheritance the security of channeling investments through a trusted family member and security in having a home to return to it is pointed out that the altruism and family remittances from urban migration were strategies that bridged the simple dynamic of either urban development or rural development impacting on family welfare it is suggested that household models of economy adopt some measure to express the relationship of household wealth to remittances from urban migrants

large cash transfers to the elderly in south africa we examine the social pension in south africa where large cash sums about twice the median per capita income of african households are paid to people qualified by age but irrespective of previous contributions we present the history of the scheme and use a 1993 nationally representative survey to investigate the redistributive consequences of the transfers documenting who receive the pensions their levels of living and those of their families we also look at behavioural effects particularly the effects of the cash receipts on the allocation of income to food schooling transfers and savings in south africa a large social pension about twice the median per capita income of african households is paid in cash to people qualified by age irrespective of previous contributions we present the history of the scheme and explain how such large transfers could come about in an economy in which the recipients were not only politically weak but without any political representation whatsoever we then use a 1993 nationally representative survey to investigate the redistributive consequences of the transfers documenting who receive the pensions their levels of living and those of their families we also look at behavioural effects particularly the effects of the cash receipts on the allocation of income to food schooling transfers and savings the pressing policy issue for south africans is whether it makes sense to target seven billion rand nearly 2 billion of social expenditure through the current pension schemes our analysis contributes to the discussion by documenting the redistributive and behavioural effects of the transfers we find that at least as far as immediate incidence is concerned and without allowance for behavioural effects the social pension is an effective tool of redistribution and that the households it reaches are predominantly poor because so many of the elderly among south africa s african population live with children the social pension is also effective in putting money into house

saving and liquidity constraints this paper is concerned with the theory of saving when consumers are not permitted to borrow and with the ability of such a theory to account for some of the stylized facts of saving behavior the models presented in the paper seem to account for important aspects of reality that are not explained by traditional life cycle models copyright 1991 by the econometric society

income smoothing and consumption smoothing one way that risk averse households protect consumption levels is to borrow and use insurance mechanisms another way common in low income economies is to diversify economic activities and make conservative production and employment choices households thus tend toward limiting exposure only to shocks that can be handled with available credit and insurance typically both types of mechanisms are studied independently but much more can be learned by studying them together first we obtain a more complete picture of risks costs and insurance possibilities second it opens the way to considering biases in standard tests of credit and insurance

how natural is canada s high unemployment rate abstract a reduced form price equation for canada 1956 1984 yields a stable estimate of 4 9 percent for the natural unemployment rate of men aged 25 and over with strong evidence against hysteresis once structural influences are accounted for the resulting profile for the aggregate natural unemployment rate rises smoothly from 5 5 percent in 1961 to a maximum of 8 0 percent in 1977 1978 and then declines rapidly to 6 4 percent in 1985 calculations based on an estimated production structure for the aggregate non energy sector of canada provide additional evidence against the excess real wage hypothesis and for the view that the recent fluctuations in canada s unemployment rate are mostly of the keynesian variety

links between rural poverty and the environment in developing countries asset categories and investment poverty abstract this paper presents a framework for analyzing the links between poverty and the environment in rural areas of developing countries it introduces the concept of investment poverty and relates it to other measures of poverty in analysis of these links the notion of poverty is examined in the context of categories of assets and categories of environment change with particular focus on farm household income generation and investment strategies as determinants of the links the strength and direction of the poverty environment links are shown to differ even invert depending on the composition of the assets held by the rural poor and the types of environmental problems they face policy strategies need to focus on conditioning variables that affect market development community wealth infrastructure household asset distribution and the affordability and appropriateness of natural resource conservation technologies

shocks and agricultural investment decisions abstract this study explores the impact of weather shocks on the investment decisions of farmers we distinguish between the long term effect of exposure to weather shocks measured as past exposure to deviations in average rainfall levels and the effect of weather related shocks that have recently occurred we examine how households cope with shocks in the short term in terms of consumption smoothing and the depletion of liquid assets and whether over the longer term shock exposure impacts on household investment decisions and welfare our results show that households on average manage to smooth consumption in the face of recent shocks by depleting savings and borrowing over the longer term households that are exposed to shocks invest less in productive assets leading to lower consumption levels moreover the investment strategies of these households do not appear to pay off once additional shocks occur later on

consumption insurance an evaluation of risk bearing systems in low income economies the hypothesis of full risk sharing can be taken to data from low income countries and evaluate formal and informal financial systems in many contexts idiosyncratic risks are high so credit insurance arrangements could be beneficial statistical tests reveal that households in southern india take advantage of these possibilities villages in cote d ivoire and countries in thailand do not do as well the paper includes an empirical description of the devices used to smooth consumption and a theoretical discussion of private information and incentives on ideal operating systems the full information and mechanism design frameworks provide benchmarks for policy analysis

financial intermediation and delegated monitoring this paper develops a theory of financial intermediation based on minimizing the cost of monitoring information which is useful for resolving incentive problems between borrowers and lenders it presents a characterization of the costs of providing incentives for delegated monitoring by a financial intermediary diversification within an intermediary serves to reduce these costs even in a risk neutral economy the paper presents some more general analysis of the effect of diversification on resolving incentive problems in the environment assumed in the model debt contracts with costly bankruptcy are shown to be optimal the analysis has implications for the portfolio structure and capital structure of intermediaries

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

on risk transactions and economic development in the semiarid tropics recent interest in the institutions and production relations of tropical agriculture seem to hold promise for increased collaboration between economists and anthropologists in efforts to explain existing patterns of production and socioeconomic interaction this focus on customs and on the more formal institutional arrangements is encouraging given the continuing concern for food production in much of the semiarid tropics two recent papers are particularly germane to this growing literature h p binswanger and m r rosenzweig have offered a foundation for addressing the production relations in agriculture with a general focus on conditions in south asia more recently binswanger and j mcintire provide an explanation for the major institutions and customary features of production relations in three agroclimatic subzones of the land abundant tropics that have simple technology and high transport costs 2 they also offer predictions of how these institutions and features might change in response to the opening up of subsistence economies and to population growth our approach here is consistent with this recent work in several respects first it is explanatory in that we offer possible explanations for observed behavior in the land abundant tropics where agriculture is a mixture of cropping and livestock management second it is predictive in that we draw on economic theory to hypothesize likely changes in behavior in the face of institutional change finally it is offered in the interest of stimulating a concern for the institutional preconditions of economic development by such preconditions we have in mind the institutional arrangements that can stimulate the economic development process in particular we focus on the role of transactions in the economy we do not believe that there is anything intrinsically undesirable about transactions that are restricted to a circle of family and acquaintances on the contrary such transactions play an important

determinants and effects of income diversification amongst farm households in burkina faso using four years of household data from three agroecological zones in burkina faso sahelian sudanian and guinean the article examines the determinants and effects of household income diversification harvest shortfalls and terms of trade are found to drive diversification but land constraints do not income diversification is associated with higher incomes and food consumption and more stable income and consumption over years

labour surplus as a signal for real wage adjustment austria 1968 1984 unemployment figures for austria have been running well below the oecd average since the late 1960s in fact before 1981 there was hardly any unemployment problem in austria in 1982 and 1983 unemployment rates doubled since then the upward movement has slowed down but there are no indications that austrian unemployment could drop substantially below the 5 per cent level during the second half of the 1980s see figure 1

the macroeconomic tradeoffs of price and income policies under some conditions price and income policies may succeed in reaching the objective they pursue but in all cases tradeoffs place limits on what they can achieve these tradeoffs are discussed for three kinds of objectives reducing inequalities solving the inflation unemployment dilemma and restoring business profitability the uncertainties particularly the relationship between wages and employment are emphasized copyright 1990 by the editors of the scandinavian journal of economics

disaggregated capital flows and developing countries competitiveness summary attracting capital and foreign exchange flows is crucial for developing countries yet these flows could lead to real exchange rate appreciation and may thus have detrimental effects on competitiveness jeopardizing exports and growth we investigate this dilemma by comparing the impact of six types of flows on real exchange rate behavior in a sample of 57 developing countries covering africa europe asia latin america and the middle east the results reveal that portfolio investments foreign borrowing aid and income lead to real exchange rate appreciation while remittances have disparate effects across regions foreign direct investments have no effect on the real exchange rate contributing to resolve the above dilemma

on migration and risk in ldcs the authors develop the hypothesis that aversion to risk rather than expectations of higher income is the primary motivation for rural urban migration in developing countries this hypothesis maintains that an optimizing risk averse small farmer family will try to place a family member in the urban sector in order to diversify its income portfolio an additional hypothesis related to risk is also considered at the individual rather than the family level annotation

unemployment getting the questions right in my opinion the form and conception of this conference exemplifies the right instinct for modern macroeconomics there is a fact a big unmistakable unsubtle fact essentially everywhere in the modern industrial capitalist world unemployment rates are much higher than they used to be two or three decades ago why is that if macroeconomics is good for anything it ought to be able to understand and explain that fact we should be able to produce a fairly convincing analytical account of the occurrence and persistence of unusually high unemployment rates you might think that to be a mere commonplace to what other sort of end would anyone organize a conference my experience however is that most high powered academic conferences are stimulated by purely technical developments or less often by ideological or political promotion rather than by the need to deal with an outstanding fact i do not blame anyone for this state of affairs we may not be blessed with many significant observations too big to be quibbled over and technical innovations do need to be thrashed out by experts anyway it is good to be faced by a brute fact that needs explanation it is what macroeconomics ought to be about i compliment the organizers also on a second aspect of the agenda the country by country organization of the papers we can all hope to learn something from cross country comparisons one of the few good ways we have to test analytical ideas is to see whether they can make sense of international differences in outcomes by appealing to international differences in institutional structure and historical environment the right place to start is within each country separately studied by someone who knows the peculiarities of its history and its data you might think that this too ought to be obvious but in fact the usual approach is just the opposite more often than not we fail to take institutional differences seriously one model is supposed to apply everywhere and always each country is just a point on a cross section regression or one among several essentially identical regressions leaving only grumblers to worry about what is exogenous and what is endogenous and whether simple parametrizations do justice to real differences in the way the economic mechanism functions in one place or another i have no way of knowing whether this organized effort will get anywhere in explaining high unemployment but it seems to be set up to give itself the best chance for better or worse probably for the better theoretical and empirical work are closely intertwined in macroeconomics scratch a macro theorist and you find a casual econometrician scratch a macro econometrician and you find a casual theorist usually you do not have to scratch very hard thus the discussion of the issues central to the conference has already hardened into certain characteristic forms there are questions already lying on the table that the individual country papers will be trying to answer i suspect that some

using weather variability to estimate the response of savings to transitory income in thailand this paper measures the extent to which farmers are able to use savings and dissavings to smooth consumption in response to unexpected shocks to income time series information on regional rainfall is used to construct estimates of transitory income due to rainfall shocks the relationship between these measures of transitory income and savings indicates that farm households save a significantly higher fraction of transitory income than nontransitory income jel d91 016 the incomes of farm households in developing countries are notorious for being both low and uncertain policies that increase the incomes of farmers may well be different

a discussion of belgian unemployment combining traditional concepts and disequilibrium econometrics with a gdp of less than 100 billion and exports of more than 60 billion belgium comes perhaps closer than any other country to being a small open economy consequently trends in world trade and export performance have a major impact on domestic activity whereas the impact of domestic fiscal policy is damped by import leakages table 1 presents a few figures confirming these observations

the relationship between employment and investment theoretical aspects and empirical evidence for italy the relationship between employment and investment activity in italy over the 1970 86 period is studied a theoretical model is used showing that the overall effect of ivestment on employment can either be positive or negative depending on the relative strength of three individual components of such global effect an empirical investigation which aims to look for a causal impact of investment activity on the employment rate is then undertaken the results of stationarity tests on our time series show that a distinction is made between short run and long run considerations in the case of the industry sector hence cointegration and causality analysis for this sector was performed in the case of the other sectors an regions we have to content ourselves with only the cyclical dimension of the series

consumption puzzles and precautionary savings abstract when marginal utility is convex agents accumulate savings as a precautionary measure against labor income eventualities this paper shows that precautionary savings can go a long way in making the excess growth excess smoothness and excess sensitivity features of consumption consistent with the stochastic processes of labor income observed in the u s at the microeconomic level

signaling in credit markets in this paper we show that under a variety of alternative assumptions about the private information of loan applicants a competitive market for loans is characterized by screening banks separate out loan risks by offering higher loans at higher interest rates depending on the nature of the informational asymmetry it may be that applicants with less risky projects select larger rather than smaller loans comparative statics implications are also examined in particular we explore the effects of an increase in banks cost of funds on average loan quality

risk financial markets and human capital in a developing country this paper explores the link between financial market incompleteness and human capital accumulation we examine how child school attendance responds to seasonal fluctuations in the income of agrarian households using panel data from rural india to pinpoint market imperfections we study responses to aggregate and idiosyncratic as well as to anticipated and unanticipated income shocks our main finding is that seasonal fluctuations in school attendance are a form of self insurance but one which does not result in a substantial loss of human capital on average

why does unemployment persist the main movements of unemployment correspond to fluctuations in the short run nairu around a stable long term nairu these supply side fluctuations have two main origins i variations in the number of insiders involved in wage setting ii variations in the effectiveness of the unemployed outsiders as potential job seekers the evidence of micro studies suggests that ii is more important than i and this also helps to explain the widespread shift outwards in the u v curve to derive these arguments rigorously the paper presents a simple model of efficiency wages another of collective bargaining and finally a fully dynamic model with labour market flows

shocks and asset dynamics in ethiopia abstractthis article uses household survey panel data of 416 rural households to study asset dynamics in the northern highlands of ethiopia and the response of assets to shocks the period under examination 1996 2003 was marked by severe environmental shocks including a series of droughts the article empirically studies the nature of household asset paths over time using as the point of departure the theory on precautionary savings behavior results indicate that the response of assets to weather shocks the differential effect of these shocks on liquid and less liquid forms of wealth holdings and the nature of asset dynamics are all consistent with the implications of a precautionary motive for holding wealth

precautionary saving and the timing of taxes this paper analyzes the effects of government debt and income taxes on consumption and saving in a world of infinitely lived households having uncertain and heterogeneous incomes the special structure of the model allows exact aggregation across households despite incomplete markets the effects of government debt are shown to be substantial roughly comparable to those resulting from finite horizons and crucially dependent on the length of time until the debt is repaid also anticipated changes in taxes are shown to cause anticipated changes in consumption finally an index of fiscal stance is derived

wage gaps factor shares and real wages the relationships which link real wages capital intensity and factor shares are tested as a prelude to tests of the relationship between wage rigidities and labour market institutions evidence from seven countries indicates that the evolution of factor shares is well explained by changes in capital intensity which is itself well explained by product wages and technical progress a key implication is that changes in full employment capital labour ratios have been the dominant reason for the longer run decline of profit shares in europe and japan relative to the united states it follows that changes in cyclically adjusted factor shares provide little or no information regarding the gap between the actual real wage and its full employment value

are the poor less well insured evidence on vulnerability to income risk in rural china the authors test how well consumption is insured against income risk in a panel of sampled households in rural china they estimate the risk insurance models by generalized method of moments treating income and household size as endogenous insurance exists for all wealth groups although the hypothesis of perfect insurance is universally rejected those in the poorest wealth decile are the least well insured with 40 percent of an income shock being passed on to current consumption by contrast consumption by the richest third of households is protected from almost 90 percent of an income shock the extent of insurance in a given wealth stratum varies little between poor and nonpoor areas

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

saving in developing countries theory and review in the literature on economic development much of the interest in saving has been focused on the relation between saving and growth but saving is not only about accumulation it is about smoothing consumption in the face of volatile and unpredictable income and helping to ensure the living standards of poor people whose lives are difficult and uncertain this paper develops a model of households which cannot borrow but which accumulate assets as a buffer stock to protect consumption when incomes are low such households dissave as often as they save do not accumulate assets over the long term and have on average very small asset holdings but their consumption is markedly smoother than their income much of the evidence is as consistent with this view of saving as it is incosistent with standard views of smoothing over the life cycle and with explanations of the link between saving and growth in terms of life cycle saving behavior consumption smoothing is also a useful way of thinking about government policy where volatility in the world prices of taxed commodities can generate sharp fluctuations in government revenues as well as reallocations of revenue between the private and public sectors many important policy issues in developing countries hinge on issues of consumption and smoothing and research on these issues is currently likely to be more productive than work on the relation between saving and growth

the old age security hypothesis reconsidered abstract that the introduction of a means for transferring present to future consumption other than children in a developing country will reduce the rate of population growth is shown to depend crucially on the assumption that parents do not care about the numbers or the welfare of the children they have when parents do care the conclusion no longer unambiguously follows because the new means for providing for parents old age leads to a positive income effect

expenditure behavior and children s welfare an analysis of female headed households in jamaica abstract evidence from jamaica shows that the sex and union status of the household head can have a significant influence on household expenditure behavior with implications for individual household members while the presence of a female decision maker generally increases the share of the household budget allocated to child and family goods female headed households fhhs also spend more on adult wear and less on health lower health expenditures are partially offset by the differential use of other health inputs in fhhs these differences in resource allocation may explain why poorer fhhs do not necessarily have lower children s outcomes in developing countries

are rainfed agricultural households insured evidence from five villages in vidarbha india there are several studies on risk and insurance in village economies in the developing world however there is a lack of evidence for recent decades in spite of profound changes including structural transformation and widespread market liberalization in most regions in this paper i use primary panel data from five rainfed villages in a high risk region of india and find evidence of considerable exposure as well as vulnerability to idiosyncratic and covariate risks further there is significant wealth differentiated heterogeneity in vulnerability the findings help identify the scope of public policy in improving risk management in rainfed agriculture
