the neolithic revolution from a price theoretic perspective article i nfo the adoption of agriculture during the neolithic period triggered the first demographic explosion in history when fertility returned to its original level agriculturalists were more numerous more poorly nourished and worked longer hours than their hunter gatherer ancestors we develop a dynamic price theoretic model that rationalizes these events in the short run people are lured into agriculture by the increased labor productivity of both adults and children in the long run the growth in population overrides the productivity gains and the later generations of agriculturalists end up being worse off than the hunter gatherers counter intuitively the increase in the labor productivity of children causes the long run reduction in welfare in the long run the increase in adult labor productivity only contributes to population growth 2010 elsevier b v all rights reserved

on the early holocene foraging to early agriculture we consider a world in which the mode of food production foraging or agriculture is endogenous and in which technology grows exogenously within a model of coalition formation we allow individuals to form co operative communities bands of foragers or farmers rationally at the lowest levels of technology equilibrium entails the grand coalition of foragers a co operative structure which avoids over exploitation of the environment but at a critical state of technology the co operative structure breaks down through an individually rational splintering of the band at this stage there can be an increase in work and through the over exploitation of the environment a food crisis in the end technological growth may lead to a one way transition from foraging to agriculture

a model of urban demography this study develops an overlapping generations model that involves the endogenous determination of demographic and city structure to fully analyze the social and natural changes in city populations we provide conditions under which the model exhibits the spatial features of demography observed in urban areas city centres have a lower total fertility rate than suburbs and larger cities have a lower total fertility rate than smaller cities through calibration we also show that spatial factors have a significant impact on demographic characteristics and city growth resume un modele de demographie urbaine cette etude developpe un modele de generations qui se chevauchent qui genere la determination endogene de la demographie et de la structure urbaine pour analyser pleinement les changements sociaux et culturels des populations urbaines on presente les conditions qui font que le modele genere les caracteristiques spatiales de la demographie observee dans les zones urbaines le centre ville avec un taux de fecondite plus faible que les banlieues et les grandes villes arborant une fecondite totale plus faible que les petites villes a l aide de calibration on montre que les facteurs spatiaux ont un impact significatif sur les caracteristiques demographiques et la croissance des villes

a theory of real wage growth in ldcs abstract a general equilibrium framework is presented to explain a variety of developmental experiences the demand side is modelled by assuming a system of preferences that incorporate engel s law in a stark way the framework explains why poverty might be impervious to industrial progress in some countries it also explains why countries which have been able to boost the exports of manufactured goods have been more successful in raising real wages in their economies than countries which have continued to export primary goods the framework indicates how the initial conditions in terms of the level and distribution of wealth influence the growth of real wages in an economy

sex equality and growth abstract we set up a model of economic and demographic long run development where inequality in income and reproductive success polygynous mating plays a central role the model generates a slow and gradual compression of the income gap between landholders and landless together with rising levels of human capital this process spurts at some stage as society endogenously transits into sustained growth simultaneously inequality in income and reproductive success drops society becomes monogamous

intensive and extensive margins of fertility capital accumulation and economic welfare abstract this paper investigates the impact of low fertility on long term capital accumulation and economic welfare we find that the impact differs depending on whether the low fertility arises from a decrease in the fertility of mothers the intensive margin of fertility or the motherhood rate the extensive margin of fertility we show that an increase in the fertility of mothers decreases the capital stock and economic welfare conversely we identify a u shaped relationship between the extensive margin of fertility and the capital stock because of the existence of two opposing effects such that the decline in fertility may reduce economic welfare furthermore we show that an intragenerational income redistribution policy can eliminate the welfare loss resulting from the incomplete market

socially optimal social security and education subsidization in a dynastic model with human capital externalities fertility and endogenous growth abstract this paper considers socially optimal government policies in a dynastic family model with physical capital human capital endogenous fertility and positive spillovers from average human capital such spillovers reduce human capital investment but raise fertility from their social optimum we first characterize the social optimum with a non convex feasible set due to the quantity quality tradeoff concerning children we then show that social security and education subsidization together financed by labor income taxes can fully eliminate the efficiency losses of the spillovers and achieve the social optimum under plausible conditions however none of the policies can do so alone

climatic fluctuations and the diffusion of agriculture this research examines the climatic origins of the diffusion of neolithic agriculture across countries and archaeological sites the theory suggests that a foraging society s history of climatic shocks shaped the timing of its adoption of farming specifically as long as climatic disturbances did not lead to a collapse of the underlying resource base the rate at which hunter gatherers were climatically propelled to experiment with their habitats determined the accumulation of tacit knowledge complementary to farming consistent with the proposed hypothesis the empirical investigation demonstrates that conditional on biogeographic endowments climatic volatility has a hump shaped effect on the timing of the adoption of agriculture

a bioeconomic view of the neolithic transition to agriculture adoption of agriculture at the expense of hunting and gathering was the dramatic precondition for all modern civilization recent data suggest that because of this transition humans initially were more disease prone smaller less nourished and shorter lived to explain why individuals chose agriculture over hunting and gathering this paper develops a simple model of the evolution of preferences over the quality and quantity of children as would have been generated by our long history as a species these preferences would have induced the choice of agriculture but also would have led to these otherwise puzzling health effects l adoption de l agriculture en remplacement de la chasse et de la cueillette a ete une condition prealable dramatique pour toutes les civilisations modernes des donnees recentes suggerent cependant que en consequence de cette transition les humains sont devenus dans les premiers temps apres la transition davantage vulnerables a la maladie ont vu leur esperance de vie diminuer ont ete moins bien nourris et sont devenus plus petits pourquoi alors est ce que des individus qui avaient le choix entre deux systemes economiques ont choisi l agriculture pour expliquer ce choix ce memoire developpe un modele simple de l evolution des preferences quant a la qualite et la quantite des enfants celles ci auraient ete engendrees par notre longue histoire en tant qu espece ces preferences auraient engendre le choix de l agriculture mais auraient aussi entraine d autre part ces effets deconcertants sur la sante

fertility choice land and the malthusian hypothesis in a standard overlapping generations growth model with a fixed amount of land and endogenous fertility the competitive economy converges to a steady state with a zero population growth rate and positive consumption per capita the malthusian hypothesis is interpreted as a positive statement about the relationship between population growth and consumption per capita when production exhibits diminishing returns to labor and there is a fixed amount of land essential for production even when individuals care only about the number of their children and not about their children s welfare the equilibrium is such that they eventually would choose to have only one child for each adult hence if malthus s positive check on population is the result of the response of optimizing agents to competitively determined prices malthus s pessimistic conjecture is not necessarily true even though his other assumptions hold from authors

the baby boom and baby bust what caused the baby boom and can it be explained within the context of the secular decline in fertility that has occurred over the last 200 years the hypothesis is that a the secular decline in fertility is due to the relentless rise in real wages that increased the opportunity cost of having children b the baby boom is explained by an atypical burst of technological progress in the household sector that occurred in the middle of the last century this lowered the cost of having children a model is developed in an attempt to account quantitatively for both the baby boom and bust

why does asset inequality affect unemployment a study of the demand composition problem abstract this paper is devoted to a general equilibrium analysis of the relationship between the inequality in asset holdings and the aggregate levels of output and employment in a developing economy since luxuries and basic goods compete for the use of the same scarce resources unemployment is concieved as a mechanism whereby the market demand for basic goods can be limited to a sufficiently low level so that the high demand for luxuries can be met the ambiguous effects of capital accumulation on employment are also examined

an intergenerational model of population growth the problem of population growth has been only partially formulated in an intertemporal context therefore a link between population theory and economic growth theory is still missing this paper attempts to provide such a link by analyzing an intergenerational model of optimum population growth the model accommodates the idea that decisions on increases in population should consider the new population s quality of life this concept is elaborated upon in a static framework by gary becker and gregg lewis dennis de tray and robert willis other literature on population growth such as harold votey disregards this consideration altogether 2 more explicitly this paper assumes that the utility of each generation is a function of the level of its consumption and the number and utility of the newly born people we are thus led to consider the utility of an infinite number of generations this model differs from paul samuelson s intergenerational model of pure consumption in which the utility of each generation depends only on that generation s own consumption recently philip neher 1971 analyzed a model of fertility in primitive economies it is based on the assumption that parents use children as investments to insure future consumption needs neher s analysis focuses entirely on the pension motive for having children 3 our model assumes that fertility is determined so as to balance the parents welfare derived from additional children against that derived from the children s quality of life we first outline a general model of optimum population growth in order to discuss explicitly various economic aspects of population we use a simple case in the analysis section i sets up the basic model

more on marriage fertility and the distribution of income according to pareto 1896 the distribution of income depends on the nature of the people comprising a society on the organization of the latter and also in part on chance in the model developed here the nature of the people is captured by attitudes toward marriage divorce fertility and children singles search for mates in a marriage market married agents bargain about work and the quantity and quality of children they can divorce social policies such as child support requirements reflect the organization of the society finally chance is modeled by randomness in income marriage opportunities and marital bliss

the problem of population and growth a review of the literature from malthus to contemporary models of endogenous population and endogenous growth abstract this paper deals with the evolution of the literature on the problem of population and growth from the classical period to the recent literature on endogenous growth and development the problem concerns two distinct issues 1 how to explain the observed covariation of the levels and rates of growth of per capita income and population size over time and space and 2 how to improve the human condition represented by these variables through an accommodating social policy the evolution of the literature we survey is reflected by the progressive treatment of key variables as endogenous rather than exogenous to the growth process it is also reflected by a shift from the historical concern about population explosion and its implications for growth to the more recent concern about the association between growth and population implosion in many developed countries

education democracy and growth abstract this note presents a model of endogenous growth where redistribution determined by a political equilibrium is in the form of public education it is shown that there need not be a negative relationship between growth and redistribution as public education increases the level of human capital in the conomy and at the same time tends to produce a more even income distribution

macrodynamic adjustment mechanisms in a dual semi industrialized economy abstract the interplay between agriculture and the rest of the economy and the importance of the income distribution have been central to the macroeconomic analyses of semi industrialized economies a macrodynamic model is developed to investigate the adjustment mechanisms in the medium run it is shown how the roles of agriculture and income distribution depend on the macroeconomic situation and how the medium run adjustments may differ from short run effects

can government enforcement permanently alter fertility the case of china i introduction in developing countries per capita output growth objectives are often stymied by high birth rates 1 traditional values ignorance of birth control technology and labor intensive farming are all factors which contribute to high fertility rates for those reasons many developing countries experiencing high birth rates adopt population control policies while most programs combine educational efforts with some form of persuasion many also provide strong economic disincentives to high fertility 2 of particular interest from this vantage point is the experience of the people s republic of china which stands alone in its use of quotas on child bearing decisions 3 china s population control policy began with a massive campaign in 1953 reversing an earlier pro natalist stance however that campaign was curtailed by the political turmoil arising from the great leap forward and the cultural revolution population control programs resumed in 1970 with the issuance and enforcement of three reproductive norms late marriage longer spacing between births and fewer children in 1979 the authorities went even further allowing each household to have only one child interest in china s experience arises not only from the severity of the restrictions but also due to the government s ability to enforce them the feasibility of enforcing these restrictions is a result of the deep penetration of the communist party into most aspects of an individual s life including its control over housing employment and salaries 4 however despite the government s extensive involvement in birth planning those who study chinese demography have debated the extent to which government policies are responsible for the large fertility decline in the 1970s 5 this paper uses recent advances in economic theory and econometrics to quantitatively assess the main sources of fertility fluctuations in china specifically we employ a model with endogenous fertility choice which modifies the framework of razin and ben zion 1975 and barro and becker 1989 6 in contrast to other papers we focus on the relationship between government enforcement of population control policies and fertility outcomes we also allow the fertility rate to be affected by 1 household preferences including alterations in taste as well as in education health care and the changing role of women and 2 production technology which mostly captures changes in agricultural output or income we perform simple comparative static analysis to examine long cycles in fertility and output and characterize the transitional dynamics which govern short cycles easterlin 1968 and lee and loschky 1987 provide nice discussions of long fertility cycles the long run steady state predictions will be used to identify the empirical structural vector autoregression var system as well as interpret the underlying structural disturbances additionally the transitional dynamics results can be compared to the estimated dynamic structure finally we employ a structural var as in blanchard and quah 1989 and ahmed ickes wang and yoo 1993 to econometrically disentangle the relative contributions of policy and economic development factors to changes in fertility growth the structural disturbances include a change in the government s enforcement power a technological advance in agricultural production and a preference shift toward a higher fertility rate all of which are capable of generating both short and long cycles in fertility and output we find that government enforcement power has a significant negative effect on fertility accounting for about one third of the variance of the forecast error for fertility growth after the first year an expansion in agricultural output on the other hand yields a short run positive impact on fertility growth and is responsible for almost one fifth of fertility growth variations furthermore while theoretically all shocks have the potential to generate long cycles only preference shifts have statistically significant long run effects

slavery and other property rights the institution of slavery is found mostly at intermediate stages of agricultural development and less often among hunter gatherers and advanced agrarian societies we explain this pattern in a growth model with land and labor as inputs in production and an endogenously determined property rights institution the economy endogenously transits from an egalitarian state with equal property rights to a despotic slave society where the elite own both people and land thereafter it endogenously transits into a free labor society where the elite own the land but people are free

entertaining malthus bread circuses and economic growth we augment a simple malthusian model by allowing agents to consume something besides food whereas food in our case bread is both enjoyable and necessary for survival the other good circuses is pure entertainment it has absolutely no impact on survival but does enhance the quality of life with this very simple modification we show that whereas food supply may remain at subsistence technological change will have a great impact on the consumption of everything else most strikingly though the population remains bound by a malthusian constraint sustained improvements to living standards can no longer be ruled out we also argue that our model better fits the known historical facts the widely held belief that growth prior to the industrial revolution was flat is based largely on historical measures of food production although food supply throughout history may have been and for most individuals still is at or near subsistence levels technological advancements have brought greater convenience and comfort to wealthy and poor alike a possibility that malthus himself conceded in his later and often ignored work therefore our model not only describes historical growth patterns and demographic transitions better than traditional malthusian models but is also more in line with malthus later thinking jel classification numbers b10 i31 j1 n1 o30

peasants procreation and pensions producers and consumers durable goods yielding a stream of benefits which are compared with a stream of costs births occur if the present value of the benefits exceeds the present value of the costs the theory has been used by malthusians to rationalize the casual observation that population growth rates increase during the early stages of economic development and then perhaps fall later on as

capital accumulation income distribution and endogenous fertility in an overlapping generations general equilibrium model abstract this paper studies the intertemporal relationships among population growth income distribution inter generational social mobility skill composition of the labor force and household income in an overlapping generations general equilibrium model that aggregates household decisions regarding fertility savings and investment in human capital of children it shows that as a consequence of endogenous fertility the equilibrium path attains steady state from the second generation income tax transfer child taxation and social security taxation policies that can be devised to affect these variables are also analyzed the model provides a structural explanation for the inverse household income child quantity and negative child quality quantity relationships that are observed in developing countries it also shows that group interests may hinder the emergence of perfect capital markets with private initiatives

from malthus to modern growth can epidemics explain the three regimes we model demographic and economic long run development in a setting where mortality is endogenous and subject to epidemic shocks the model replicates the full transition from malthusian stagnation to modern growth consistent with the historical facts the economy also passes an intermediate post malthusian phase where growth rates of both population and per capita income increase simultaneously as mortality rates fall and become less volatile the escape from the malthusian trap is the result of a series of mild epidemic shocks making it inevitable at some stage but its timing random calibrations show that it can differ by thousands of generations absent differences in exogenous parameters

social articulation as a condition for equitable growth abstract a formal model is developed to establish the structural conditions that result in growth being progressive or regressive on the personal distribution of income these conditions include 1 intersectoral investment priorities between wage goods and luxuries and 2 the state of the levels and distribution of incomes which determines the social origin of demand for different sectors of the economy the particular combinations of investment and income structures that result in equalizing social articulation or unequalizing growth social disarticulation are derived we show empirically that the structural conditions that allowed rapid but unequalizing growth in brazil between 1968 and 1977 were those of social disarticulation

a note on social articulation abstract de janvry and sadoulet 1983 present a model of unequalizing growth and the closure rule of the model is discussed in this note it is shown that income distribution in the model is determined by the market clearing mechanism in the wage goods market and how the condition for social articulation is related to the excess demand function on the wage goods market

growth distribution and sectoral heterogeneity reading the kaleckians in latin america abstract the aim of this paper is to explore a parallelism between two episodes in the history of economic thought in order to suggest that the interaction between them can contribute to the research on kaleckian growth and distribution models first a brief summary of the theoretical development from steindl s stagnationist claims to the debate about demand regimes is offered then a more detailed account is provided of the latin american debate that began with furtado s stagnationist claims and resulted in the formulation of models of social articulation and disarticulation finally an analytical classification of kaleckian and latin american growth and distribution models is provided indicating the way in which sectoral heterogeneity and demand composition can act as a plausible link between growth and distribution

economic geography fertility and migration abstract this paper analyzes the relationship among economic geography fertility and migration the empirical evidence presented reveals that persistent regional variations in fertility exist within a country and that regional total fertility rates are negatively related to regional population density a two period overlapping generations model of endogenous fertility incorporating n regions agglomeration economies and congestion diseconomies is constructed to explain this negative relationship while agglomeration economies have both positive income and negative substitution effects on fertility congestion diseconomies have a negative income effect on it combined with the mobility of people interaction among these effects generates the negative relationship as a steady state equilibrium outcome it is also shown that net migration from regions with lower population density to regions with higher population density occurs in an equilibrium which in turn maintains the regional variations in fertility

the pay as you go pension system as fertility insurance and an enforcement device a paygo system may serve as insurance against not having children and as an enforcement device for ungrateful children who are unwilling to pay their parents a pension in fact the latter was bismarck s historic motive for introducing this system it is true that the paygo system reduces the investment in human capital but if it is run on a sufficiently small scale it may nevertheless bring about a welfare improvement if on the other hand the scale of the system is so large that parents bequeath some of their pensions to their children it is overdrawn and creates unnecessarily strong disincentives for human capital investment

population and the environment a parable of firewood and other tales the author analyzes the relationship between population and the environment with a focus on the role which environmental degradation and natural resources depletion may play in producing the population pressure which lies behind such degradation and depletion especially in developing countries the principal conclusion of this analysis is that the possibilities for a stable equilibrium between human population and its environment are quite limited i show that parental altruism toward their children can only make matters worse if socially unchecked by leading to an increase of the birthrate in every environmental state in comparison with that which would occur in its absence excerpt

financial fragility and economic fluctuations abstract this paper proposes a simple prototype model that describes the complex dynamics of a sophisticated monetary economy the interaction between the current and intertemporal financial constraints on economic units brings about irregular fluctuations at both micro and macro levels we use qualitative dynamic analysis and numerical simulations to investigate the interaction between financial fragility modeled in terms of structural instability and dynamically unstable financial fluctuations the model suggested recently by one of the authors is here reformulated in more operational terms and extended in a number of new directions

the brain drain and the world distribution of income abstract skilled emigration or brain drain from developing to developed countries is becoming the dominant pattern of international migration today such migration is likely to affect the world distribution of income both directly through the mobility of people and indirectly as the prospect of migration affects the rate of return to education in both the sending and receiving economies this migration pattern will therefore affect human capital accumulation and fertility decisions in both the sending and receiving economies this paper analyzes these effects in a dynamic two country model of the world economy where agents in both countries make optimal fertility and human capital decisions the implications of the analysis for the world distribution of income are derived in the light of recent empirical findings of the brain drain literature the analysis shows that the current trend towards predominantly skilled emigration from poor to rich countries may in the long run increase inequality in the world distribution of income as relatively poor countries grow large in terms of population in the short run however it is possible for world inequality to fall due to rises in gdp per capita in large developing economies with sufficiently low skilled emigration rates

the u s demographic transition between 1800 and 1940 the u s went through a dramatic demographic transition in 1800 the average woman had 7 children and 94 percent of the population lived in rural areas by 1940 the average woman birthed just 2 kids and only 43 percent of populace lived in the country the question is what accounted for this shift in the demographic landscape the answer given here is that technological progress in agriculture and manufacturing explains these facts

causality and interdependence in pasinetti s works and in the modern classical approach the formal representation of economic theories normally takes the form of a model that is a system of equations which connect the endogenous variables with the values of the parameters which are taken as given sometimes it is possible to identify one or more equations which are able to determine a subset of endogenous variables priorly and independently of the other equations and of the value taken by the remaining variables of the system the first group of equations and variables are thus said to determine causally the remaining variables in pasinetti s works this notion of causality has often been emphasized as a formal property having the burden to convey some deep economic meaning in this work we will go through those pasinetti s works where this notion of causality plays a central role with the purpose to contextualize it within the econometric debate of the sixties to enucleate its economic meaning and to show its connections with other fields of the modern classical approach

from foraging to farming explaining the neolithic revolution abstract this article reviews the main theories about the prehistoric shift from hunting and gathering to agriculture the transition also known as the neolithic revolution was ultimately necessary to the rise of modern civilization by creating the foundation for the later process of industrialization and sustained economic growth the article provides a brief historical survey of the leading hypotheses concerning the rise of agriculture proposed in the archaeological and anthropological literature it then turns to a more detailed review of the theories put forth in the economic literature

sectoral balance in development a survey abstract this paper surveys the literature on sectoral balance to see how sectoral imbalances can retard economic development it examines definitions of sectors and balance provides background facts theories and planning tools reviews the debate on balanced growth and surveys two sector models of agriculture industry consumption investment and luxury basics interaction the open economy and the role of service nonmarket and unproductive sectors it argues that the examination of important development issues requires multisectoral analysis incorporating the insights of several of these models and that alternative models with different structural characteristics deserve attention

disarticulation and human welfare in less developed countries disarticulation refers to the juxtaposition of economic sectors with different levels of development and productivity disarticulation is hypothesized to have a negative effect on social well being net of economic development because it inhibits the spread effects generally thought to be associated with economic growth findings are in accord with this hypothesis although the relationship is complex the strongest effects of disarticulation are found among the poorest nations the concept of disarticulation opens a new and promising avenue of research that may help to resolve contradictory findings of recent research on the political economy of growth

population growth and human capital investments theory and evidence this paper presents evidence from empirical studies that test hypotheses derived from models of household behavior pertaining to the interrelationships among population growth human capital and economic development these studies have exploited quasi natural experiments embodied in the cross area variability in the wage rates of children in a number of low income countries the intercouple variation in the biological propensity to conceive and the geographically selective introduction of new high yielding seed varieties in india in the period 1961 71 the different varieties of evidence support the hypotheses that alterations in the returns to human capital associated with exogenous technical change lead simultaneously to increases in human capital investments and to reductions in fertility and that the costliness of fertility control is a significant but modest factor in inhibiting human capital investments

can minimum wages cause a big push evidence from indonesia big push models suggest that local product demand can create multiple labor market equilibria one featuring high wages formalization and high demand and one with low wages informality and low demand i demonstrate that minimum wages may coordinate development at the high wage equilibrium using data from 1990s indonesia where minimum wages increased in a varied way i develop a difference in spatial differences estimator which weakens the common trend assumption of difference in differences estimation reveals strong trends in support of a big push formal employment increases and informal employment decreases in response to the minimum wage local product demand also increases and this formalization occurs only in the non tradable industrializable industries suggested by the model while employment in tradable and non industrializable industries also conforms to model predictions
