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

cheap children and the persistence of poverty this paper develops a theory of fertility that offers an explanation for the persistence of poverty within and across countries if educated individuals have a comparative advantage in raising educated children then parental fertility choice is shown to give rise to a poverty trap in which the poor choose high fertility rates with low investment in child quality moreover the impact of child quality choice on economic performance is amplified by the diluting effect of higher fertility on physical capital accumulation the theory proposes insights regarding the effects of inequality globalisation and life expectancy on economic growth and demographic transitions this paper develops a theory of fertility and child educational choice that offers an explanation for the persistence of poverty within and across countries the joint determination of the quality education and quantity of children in a household is studied under the key assumption that individuals productivity as teachers increases with their own human capital in contrast the minimum time cost associated with raising a child regardless of the child s quality the quantity cost is not affected by parental education as a result the price of child quantity relative to the price of child quality increases with individuals wages in particular for low wage individuals for whom the opportunity cost of time is low children of minimal quality are cheap this assumption therefore generates a comparative advantage for the poor in child quantity whereas high wage educated individuals have a comparative advantage in raising quality children consistent with the well known evidence poor households thus choose relatively high fertility rates with relatively low investment in their offspring s education and therefore their offspring are poor as well in contrast high income families choose low fertility rates with high investment in education and therefore high income persists in the dynasty evidence from the us provided by hanushek 1992 suggests that a trade off between quantity and quality of children does indeed exist hanushek argues that movements in family size could explain over half the variance in some test scores and that the elasticity of achievements with respect to the number of children in the family is 0 03 implying that the annual achievement growth of each child in a family will fall about 2 when a second child is added and about 0 5 when a sixth child is added 1

social protection food security and asset formation summary the last two decades have seen a rapid rise in social protection programs and studies that assess their impacts on a large number of domains we construct a new database of studies of these programs that report impacts on food security outcomes and asset formation our meta analysis finds that social protection programs improve both the quantity and quality of food consumed by beneficiaries the magnitudes of these effect sizes are meaningful the average social protection program increases the value of food consumed expenditure by 13 and caloric acquisition by 8 food expenditure rises faster than caloric acquisition because households use transfers to improve the quality of their diet most notably increasing their consumption of calories from animal source foods since the consumption of animal source foods in these populations is low and because there are significant nutritional benefits to increasing the consumption of these this is a positive outcome our meta analysis also finds that social protection programs lead to increased asset holdings as measured by livestock non farm productive assets farm productive assets and savings there is no impact on land holdings though the number of studies that assess these is small

wealth inequality and collective action abstract we study the effect of inequality in the distribution of endowments of private inputs e g land wealth that are complementary in production with collective inputs e g contribution to public goods such as irrigation and extraction from common property resources on efficiency in a class of collective action problems we focus on characterizing the joint surplus maximizing level of inequality making due distinction between contributors and non contributors in a framework that allows us to consider a wide variety of collective action problems ranging from pure public goods to impure public goods to commons we show that while efficiency increases with greater equality within the groups of contributors and non contributors so long the externalities positive or negative are significant there is an optimal degree of inequality between these groups

poverty reduction during 1990 2013 did millennium development goals adoption and state capacity matter abstract while poverty reduction remains central in the post 2015 agenda its determinants remain debated in the literature especially the role of structural conditions related to governance this paper provides an assessment of two key dimensions the global adoption of mdgs and state capacity we do so by studying whether they facilitated convergence in income poverty measures using cross section and panel methods with data on 89 developing economies for the period 1990 2013 we find that poverty headcount and gap measures tended to decrease faster in countries with initially higher income poverty such convergence accelerated after 2000 suggesting that mdgs adoption was instrumental to poverty reduction however this still leaves unexplained substantial variation in poverty reduction performance across countries such variation is explained by state capacity countries with greater ability to administer their territories in 1990 experienced faster income poverty reduction and were more likely to have achieved the mdg target this result is insensitive to robust regression methods and to a large set of controls initial level of income dependence on natural resources education and health inputs dependence on foreign aid ethnic fractionalization regional effects and a set of governance variables as good governance and effective institutions are included in the sustainable development goals this result provides empirical justification for this move suggesting that more effective states could be crucial to sustain the development progress achieved so far

symbiosis vs crowding out the interaction of formal and informal credit markets in developing countries abstract it is a common observation in many developing countries that enterprises are active borrowers in both formal and informal credit markets we propose a model in which the formal sector s superior ability in deposit mobilization is traded off against the informational advantage that lenders in the informal sector enjoy the formal sector can screen borrowers by providing only partial financing for projects thereby forcing borrowers to resort to the informal sector for the remainder of the loan we use the model to predict how the market structure responds to changes in the environment and we consider the policy implications of various forms of government intervention

how can safety nets contribute to economic growth the paper provides an up to date and selective review of the literature on how social safety nets contribute to growth the evidence is carefully chosen to show how safety nets have the potential to overcome constraints on growth linked to market failures and is organized into 4 distinct pathways i encouraging asset accumulation by changing incentives and by addressing imperfections in financial markets caused by constraints in obtaining credit and from information asymmetries overcoming such failures helps households to invest into their human capital or productive assets ii failures in insurance markets especially in low income setting safety nets are assisting in managing risk both ex post and ex ante iii safety nets are overcoming failure to create assets and other local economy complementary factors to household level investments iv safety nets are shown to relax political constraints on policy safety nets have a dual objective of directly alleviating poverty through transfers to the poor and of triggering higher growth for the poor however the trade off between the dual objectives of equity and growth is not eliminated by the potential for productive safety nets this remains critical for designing social policies

financial frictions occupational choice and economic inequality we develop a quantitative theory of entrepreneurship income inequality and nancial frictions disciplined with household data from brazil the theory extends lucas 1978 by modeling heterogeneity in two skills working and managerial skills consistently with the evidence the theory implies three occupational categories workers employers and self employed entrepreneurs we nd that the correlation between working and managerial skills matters importantly for the distribution of earnings across occupations and for the quantitative implications of nancial frictions we also nd

occupational choice and the private equity premium puzzle abstract this paper suggests a solution to what has become known as the private equity premium puzzle moskowitz and vissing jorgensen 2002 we interpret occupational choice as a dynamic portfolio choice problem of a life cycle investor facinga liquidity constraint and imperfect information about the profitability of potential businesses in this setting becoming an entrepreneur is equivalent to investing in non traded private equity capital subject to transaction costs we model the return on private equity as the sum of two components the individual ability of the entrepreneur and idiosyncratic business risk information is imperfect because only entrepreneurs observe their own business risk realizations using numerical techniques we find that the model generates the observed return structure for private equity using standard crra preferences and fully rational expectations

do social protection transfers reduce poverty and vulnerability to poverty in pakistan household level evidence from punjab empirical studies in different developing countries have investigated the impact of social protection sp on ex post poverty however few studies analysed the impact of sp on ex ante vulnerability to poverty vtp this paper contributes to the literature by evaluating the impact of sp on vulnerability to poverty vtp and poverty rates among households in the punjab province of pakistan a hierarchical modelling approach is used to analyse the multiple indicator cluster survey mics 2011 data of about 90 000 households matching methods and simultaneous endogenous switching regression are used to control for potential selection bias and estimate average treatment effects our results show that sp has a positive impact in reducing household poverty and vtp but this impact is mainly driven by a short term flood relief cash transfer programme pension of government employees and households regular purchase from utility store network

inequality control rights and rent seeking sugar cooperatives in maharashtra this paper presents a theory of rent seeking within farmer cooperatives in which inequality of asset ownership affects relative control rights of different groups of members the two key assumptions are constraints on lump sum transfers from poorer members and disproportionate control rights wielded by wealthier members transfers of rents to the latter are achieved by depressing prices paid for inputs supplied by members and diverting resulting retained earnings the theory predicts that increased heterogeneity of landholdings in the local area causes increased inefficiency by inducing a lower input price and a lower level of installed crushing capacity predictions concerning the effect of the distribution of local landownership on sugarcane price capacity levels and participation rates of different classes of farmers are confirmed by data from nearly 100 sugar cooperatives in the indian state of maharashtra over the period 1971 93

using asset allocation to protect spending the management of an educational endowment or other income producing portfolio involves two strategic decisions at the fund level asset allocation and choice of a spending rule traditionally these two decisions are linked for example to preserve capital on average but the optimal link would be more dynamic this article describes a new protective strategy that links spending and asset allocation in a way that preserves spending power in down markets but participates significantly in up markets the strategy is similar to constant proportions portfolio insurance in that part of the fund is maintained in safe assets to preserve the value needed for continued expenditures like portfolio insurance the strategy outperforms traditional strategies when markets are persistently up or persistently down but underperforms when portfolios are whipsawed by alternating ups and downs

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

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

social security and individual welfare precautionary saving borrowing constraints and the payroll tax this paper examines the impact of social security on national saving and individual welfare in the presence of realistic capital market imperfections market failure in the private provision of annuities and restrictions on borrowing against anticipated future wages the introduction of social security increases lifetime welfare and reduces national saving if borrowing restrictions are absent however the increase in individual welfare is reduced and in some cases eliminated when borrowing constraints are taken into consideration the substantial difference suggests the importance of reexamining the proportional payroll tax finance of social security copyright 1987 by american economic association

the british origins of the us endowment model the us endowment model is an approach to investing popularized by yale university that emphasizes diversification and active management of equity oriented illiquid assets the writings of the british economist john maynard keynes were a considerable influence on the investment philosophy of yale s chief investment officer david swensen how did keynes gain these insights we track keynes s experiences managing the king s college cambridge endowment and show how some of the lessons he learned remain relevant to endowments and foundations today

retrospectives john maynard keynes investment innovator john maynard keynes made a major contribution to the development of professional investment management based on detailed archival research at king s college cambridge we describe keynes investment philosophy his investment performance and the evolution of his investment approach as the manager of a large educational endowment his portfolios were actively managed and unconventional he was an investment innovator both in making a substantial allocation to the then new institutional asset class of common stocks as well as in championing value investing

limited enforcement financial intermediation and economic development a quantitative assessment we present a model of economic development where the importance of financial differences caused by limited enforcement can be measured economies where enforcement is poor direct less capital to the production sector and employ less efficient technologies calibrated simulations reveal that the resulting effect on output is large furthermore the model correctly predicts that the average scale of production should rise with the quality of enforcement finally we find that the importance of limited enforcement rises with the importance of capital in production

social protection and poverty reduction global patterns and some targets summary this paper argues that social protection needs to be on the post 2015 agenda as a key element of the discourse based on a global social protection data set it estimates that social protection programs are currently preventing 150 million people from falling into poverty even if all low income countries could achieve the very best targeting efficiency observed in the world only 50 could halve the poverty gap through social protection for half of low income countries and for over a fifth of all countries in the sample the issue is one of budgetary adequacy not targeting efficiency

credit market imperfections and persistent unemployment abstract this paper develops the thesis that credit market frictions may be an important contributor to high unemployment in europe when a change in the technological regime necessitates the creation of new firms this can happen relatively rapidly in the u s where credit markets function efficiently in contrast in europe job creation is constrained by credit market imperfections so unemployment rises and remains high for an extended period the data show that there has not been slower growth in the most credit dependent industries in europe relative to the u s but the share of employment in these industries is lower than in the u s this suggests that although credit market imperfections are unlikely to have been the major cause of the increase in european unemployment they may have played some role in limiting european employment growth

limited liability contracts between principal and agent abstract the optimal strategy of the principal is examined in an environment where there are ex post limitations on the maximum penalty that can be imposed on a riskneutral agent contrary to the case in which such limitations are not imposed it is in the principal s interest to deliberately forego the opportunity to induce socially efficient behavior and to instead design a contract that induces the agent to realize an efficient outcome only in the most productive state of nature and perhaps in certain very unproductive states the properties of the contract are examined in detail

secrets of the academy the drivers of university endowment success university endowments have received much attention recently for their superior investment returns compared with other institutional investors this study documents trends in college and university endowment returns and investments in the united states between 1992 and 2005 using data on over a thousand schools such endowments have generally performed well over this time period with a median growth rate of 7 4 percent per year and median return of 6 9 percent this sector has been dominated both in size and performance by the endowments of elite universities such as the ivy league schools the top 20 endowments grew more than 9 percent annually on a real basis between 1992 and 2005 as of 2007 the two largest endowments belonging to harvard and yale have grown to 35 billion and 22 billion in size respectively much of the growth in endowment size has been driven by investment performance as we will show in the paper the top endowments posted impressive returns in 2005 averaging a net real return of 12 3 percent compared to 4 4 percent posted by the s p 500 index in the same year we investigate the underlying drivers of these high returns and show that performance is related to the size of endowment the quality of the student body and the use of alternative investments we caution ordinary investors that mimicking the strategies of the top endowments would not necessarily result in similar returns

testing agency theory with entrepreneur effort and wealth we develop a principal agent model in an entrepreneurial setting and test the model s predictions using unique data on entrepreneurial effort and wealth in privately held firms accounting for unobserved firm heterogeneity using instrumental variables techniques we find that entrepreneurial ownership shares increase with outside wealth and decrease with firm risk effort increases with ownership and effort increases firm performance the magnitude of the effects in the cross section of firms suggests that agency costs may help explain why entrepreneurs concentrate large fractions of their wealth in firm equity

what would yale do if it were taxable corrected january 2016 the distinctive financial goals and constraints of ultra high net worth individuals together with their aggregate growth in assets have led to the emergence of new institutional investing which includes the best practices from institutional investors but also incorporates the critical element of tax management the authors design new institutional asset allocations that incorporate traditional investment metrics in a tax aware setting specifically they show how risk and after tax returns need to be combined from inception when seeking an optimal after tax asset allocation diversification is especially important for taxable investors because low asset class correlations can facilitate the inclusion of attractive but tax inefficient asset classes in a tax aware allocation

short termism of long term investors the investment behaviour of dutch insurance companies and pension funds countercyclical investment strategies of large institutional investors such as insurance companies and pension funds can support financial stability while procyclical investment behaviour is consi

experimentation and the returns to entrepreneurship previous studies have argued that entrepreneurs earn less and bear more risk than salaried workers with otherwise similar characteristics in a simple model of entrepreneurship i show that estimates of mean and variance of returns to entrepreneurship used by these previous studies are biased as they fail to account for the option value of experimenting with new ideas using longitudinal data i find patterns that are consistent with entrepreneurship as experimentation and returns to entrepreneurship that are more attractive than established by previous research

an analysis of the s p 500 index and cowles s extensions price indexes and stock returns 1870 1999 this article provides a consistent monthly stock price index from january 1871 through 1999 the broadly defined s p weekly index is reconstructed from 1918 and carried forward as the s p 500 composite index to the present cowles s monthly index is improved in order to provide month end estimates from february 1885 cowles s estimates of dividends and earnings for this index from 1871 are reevaluated and are carried forward until spliced to the s p daily estimates that began in 1957 the result is a monthly index of prices dividends and earnings based on consistent definitions over a period of 130 years

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

debt constrained asset markets we develop a theory of general equilibrium with endogenous debt limits in the form of individual rationality constraints similar to those in the dynamic consistency literature if an agent defaults on a contract he can be excluded from future contingent claims markets trading and can have his assets seized he cannot be excluded from spot markets trading however and he has some private endowments that cannot be seized all information is publicly held and common knowledge and there is a complete set of contingent claims markets since there is complete information an agent cannot enter into a contract in which he would have an incentive to default in some state in general there is only partial insurance variations in consumption may be imperfectly correlated across agents interest rates may be lower than they would be without constraints and equilibria may be pareto ranked

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