market returns transfers and demand for schooling in malaysia 1976 89 if parents expect higher market returns to schooling or additional transfers from their children they invest more in their children s schooling results from models of schooling demand using data from the malaysian family life surveys of 1976 and 1989 suggest that market returns of mothers but not fathers positively affected schooling the propensity for parents to spend time with their parents had a small positive effect on education of daughters but other transfers had a weak negative effect the results suggest that if one generation perceives a low return to schooling then the next generation especially daughters pays the price of lower schooling

the rise and fall of social problems a public arenas model this paper develops a model of the process through which social problems rise and fall treating public attention as a scarce resource the model emphasizes competition and selection in the media and other arenas of public discourse linkages among public arenas produce feedback that drives the growth of social problems growth is constrained by the finite carrying capacities of public arenas by competition and by the need for sustained drama the tension between the constraints and forces for growth produces successive waves of problem definitions as problems and those who promote them compete to enter and to remain on the public agenda suggestions for empirical tests of the model are specified

models of stock returns a comparison in this paper a discrete mixture of normal distributions is proposed to explain the observed significant kurtosis fat tails and significant positive skewness in the distribution of daily rates of returns for a sample of common stocks and indexes stationarity tests on the parameter estimates of this discrete mixture of normal distributions model revealed significant differences in the mean estimates that can explain the observed skewness and significant differences in the variance estimates that can explain the observed kurtosis an alternative explanation for the observed fat tails is the symmetric student model the result of a comparison between the models is that the discrete mixture of normal distributions model has substantially more descriptive validity than the student model for many years both financial economists and statisticians have been concerned with the description of stock market returns the form of the distribution of stock returns is a crucial assumption for mean variance portfolio theory theoretical models of capital asset prices and the prices of contingent claims for example understanding the behavior of the variance is essential to option pricing models empirical tests of asset pricing models and the efficient markets hypothesis draw statistical inferences that are also conditional on distributional assumptions the most convenient assumption for financial theory and empirical methods is that the distribution of security rates of return be multivariate normal with parameters that are stationary over time since the normal distribution is stable under addition any arbitrary portfolio of stocks will also be normally distributed with the additional assumption of risk aversion mean variance theory follows furthermore the assumptions of normality and parameter stationarity are required for most of the econometric techniques typically used in empirical research tests of the normality hypothesis on the daily returns of the dow jones industrial stocks by fama 121 revealed more kurtosis fatter tails than that predicted from a sample of independent and identically distributed normal variates fama concluded from this evidence that the distribution of price changes conforms better to the stable paretian distribution with characteristic exponent

does globalization increase child labor abstract there is no empirical evidence that trade exposure per se increases child labor as trade theory and household economics lead us to expect the crosscountry evidence seems to indicate that trade reduces or at worst has no significant effect on child labor consistently with the theory a comparatively well educated labor force and active social policies appear to be conducive to a reduction in child labor for countries with a largely uneducated workforce the problem is not so much globalization as not being allowed to take part in it

strategy research governance and competence perspectives business strategy is a complex subject and is usefully examined from several perspectives this paper applies the lenses of governance and competence to the study of strategy both the governance and the competence perspectives have had the benefit of distinguished antecedents they have also had to deal with tautological reputations i begin with the governance perspective with emphasis on the six key moves through which it has been operationalized i then examine the competence perspective in these same six respects governance challenges the competence perspective to apply itself more assiduously to operationalization including the need to choose and give definition to one or more units of analysis of which the routine is a promising candidate the research challenges posed by competence to which governance can and should respond include dynamic transaction costs learning and the need to push beyond generic governance to address strategy issues faced by particular firms with their distinctive strengths and disabilities a lively research future for these two perspectives individually and in combination is projected copyright 1999 john wiley sons ltd business strategy is an expansive enterprise not only do all of the functional areas in the business school relate but strategy is by nature interdisciplinary all of the social sciences especially economics and organization theory plus contract law are implicated indeed in the high technology arena where some of the most difficult strategy issues reside engineering and the law on intellectual property rights also have a bearing of the various approaches to the study of strategy this paper focuses on the governance and competence perspectives both perspectives combine economic reasoning with organization theory as between these two the governance

jump risks and the intertemporal capital asset pricing model the specification of the stochastic process for stock prices is an important assumption underlying most equilibrium and option pricing models in modern finance this is particularly true of the continuous time capital asset pricing models where it is assumed that asset prices follow diffusion processes with continuous sample paths see merton 1973a breeden 1979 grossman and shiller 1982 the extent to which the implications of these models generalize to discontinuous sample paths is an unanswered question in theoretical finance however the answer to this question is of more than just theoretical interest since accumulated empirical evidence appears to be inconsistent with the continuous sample path assumption see rosenberg 1972 oldfield rogalski and jarrow 1977 rosenfeld 1982 one purpose of this paper is to provide some answers to this question we do this by extending merton s 1973a intertemporal asset pricing model in the special case of a constant investment opportunity set to include discontinuous sample paths for asset prices the constant investment opportunity set assumption is imposed because we are interested in obtaining sufficient conditions under which an instantaneous capital asset pricing model capm results the extension of our model to a stochastic opportunity set is discussed briefly in the text this paper investigates an economy where stock prices follow a jump diffusion process the first part of the analysis derives a sufficient condition under which an instantaneous capm will characterize equilibrium expected returns the sufficient condition is that the jump component of a stock s return must be unsystematic and diversifiable in the market portfolio the second part of the paper is an empirical investigation of the satisfaction of this condition the evidence is seen to be inconsistent with the satisfaction of this hypothesis that is the market portfolio appears to contain a jump component

economic growth and the persistence of child labor evidence from an indian city abstract this paper examines features of child labor in an area of high economic growth in western india growth was associated with an increase in the number of child workers over the last 15 years the analysis shows that children work at simple repetitive manual tasks that do not require long years of training or experience the work is low paying involves drudgery and is hazardous work forecloses the option of school education for most children in this context i argue that economic growth alone is not sufficient to eradicate child labor

the economics of child labor if child labor as a mass phenomenon occurs not because of parental selfishness but because of the parents concern for the household s survival the popular argument for banning child labor loses much of its force however this assumption about parental decision making coupled with the assumption of substitutability in production between child and adult labor could result in multiple equilibria in the labor market with one equilibrium where children work and another where adult wage is high and children do not work the paper establishes this result and discusses its policy implications copyright 1998 by american economic association

mothers employment and their children s schooling a joint multilevel analysis for india this paper studies the relationship between mothers employment and children s schooling in india using the second national family health survey the results of a multilevel probit model show that the correlation between mothers employment and their children s schooling is negative women in poorer households are more likely to work but given the negative correlation their additional income does not seem sufficient to enable children s school attendance a sensitivity analysis on wealth deciles shows that this negative relationship disappears in urban areas and becomes weaker in rural areas at the top wealth deciles

explicating political hazards and safeguards a transaction cost politics approach we apply the logical of comparative institutional analysis to the question of the governance of the relationship between private investors and the government we consider two strategies that investors may follow lobbying for the creation of a specialized political governance structure or the reliance on more general political mechanisms to influence policy in that sector on an ongoing basis we identify political hazards as crucial determinant of the choice of political governance and the transactional attributes that give rise to such hazards finally we highlight shift parameters in a nation s institutional environment that influence the choice between specialized and generalized political governance mechanisms

bureaucratic discretion or congressional control regulatory policymaking by the federal trade commission this paper extends stigler and peltzman s approach to regulation by incorporating a legislature the model yields comparative statics results and hence testable implications the paper then tests between two opposing approaches about regulatory agency behavior the first assumes agencies operate independently of the legislature and hence exercise discretion the second assumes that congress controls agency decisions the recent behavior of the federal trade commission provides the empirical setting substantial evidence is found for the specific predictions of the model including the hypothesis of systematic congressional influence over ftc decisions

uncovering the complex relationships between political risk and mne firm legitimacy insights from libya using the before after natural experiment occasioned by the arab spring in libya we explore how market and non market activity affect foreign firm legitimacy in times of political turmoil although all mnes in libya had to cultivate strong ties to qadhafi to succeed during his 40 years of rule we found that those that also invested in social benefit projects and in social ties with families with few ties to the qadhafi family earned a broad based legitimacy that helped them survive qadhafi s overthrow our findings contribute to the political risk and political behavior literature the notion that the pursuit of firm legitimacy in general and especially in the eyes of social sector actors is an effective hedge against political risk more theoretically our findings support the addition of a social sector based path to firm legitimacy in the host country that complements and may at times substitute for the government based path to foreign firm legitimacy practically our findings suggest that mnes facing severe political risk can improve their prospects for survival by investing in relationships with influential social groups and by offering goods or services that are perceived as socially valuable

electoral systems and public spending we study the effects of electoral institutions on the size and composition of public expenditure in oecd and latin american countries we emphasize the distinction between purchases of goods and services which are easier to target geographically and transfers which are easier to target across social groups we present a theoretical model in which voters anticipating government policymaking under different electoral systems have an incentive to elect representatives more prone to transfer public good spending in proportional majoritarian systems the model also predicts higher total primary spending in proportional majoritarian systems when the share of transfer spending is high low after dee ning rigorous measures of proportionality to be used in the empirical investigation we e nd considerable support for our predictions

a note on multiple general equilibria with child labor abstract it has been conjectured that the child labor market may exhibit multiple equilibria this paper develops the concept of a wage bill curve and establishes the multiple equilibrium result in a general equilibrium model thereby clarifying the circumstances where child labor should be banned

testing the bargaining hypothesis in the manufacturing sector in developing countries the bargaining power model of hc mnc host country multinational corporation interaction conceives of economic nationalism in terms of rational self interest and assumes both inherent conflict and convergent objectives in extractive industries there is strong evidence that outcomes are a function of relative bargaining power and that as power shifts to developing hcs over time the bargain obsolesces a cross national study of the bargaining model using data from 563 subsidiaries of u s manufacturing firms in forty nine developing countries indicates that while the bargaining framework is an accurate model of mnc host country relationships manufacturing is not characterized by the inherent structurally based and secular obsolescence that is found in the natural resource industries shifts in bargaining power to hcs may take place when technology is mature and global integration limited in industries characterized by changing technologies and the spread of global integration the bargain will obsolesce very slowly and the relative power of mncs may even increase over time

option pricing with stochastic volatility information time vs calendar time empirical evidence has shown that subordinated processes represent well the price changes of stocks and futures using either transaction counts or trading volume as a proxy for information arrival it supports the contention that volatility is stochastic in calendar time because of random information arrival and thus becomes stationary in information time this contention has also been supported later in theoretical models in this paper we investigate the implication of this contention to option pricing first we price the option in calendar time where the return of the underlying asset follows a jump subordinated process we extend rubinstein s rubinstein m 1976 the valuation of uncertain income streams and the valuation of options bell j econom management sci 7 407 425 and ross s ross s 1989a information and volatility the no arbitrage martingale approach to timing and resolution irrelevancy finance44 1 17 martingale valuation methodology to incorporate the pricing of volatility risk the resulting equilibrium formula requires estimating seven parameters upon implementation we then make a stochastic time change from calendar time to information time in order to obtain a stationary underlying asset return process to price the option we find that the isomorphic option has random maturity because the number of information arrivals prior to the option s calendar time expiration date is random we value the option using dynkin s dynkin e b 1965 markov processes vols i and ii springer verlag berlin and new york version of the feynman kac formula that allows for a random terminal date the resulting information time formula requires estimating only one additional parameter compared to the black scholes s in practical application in this regard the time change has reduced the computational complexity of the option pricing problem simulations show that the formula may outperform the black scholes black f m scholes 1973 the pricing of options and corporate liabilities political econom 81 637 659 and merton merton robert c 1976a option pricing when underlying stock returns are discontinuous financial econom 3 125 143 models in pricing currency options as a first attempt to derive valuation relationships in the information time economy this investigation may suggest that the information time approach is a functional alternative to the current calendar time norm it is especially suitable for deriving volatility free portfolio insurance strategies

urban influences on rural schooling in india abstract many believe that low levels of schooling in rural areas of developing economies are a consequence of the low rate of return to schooling in agriculture this belies the possibility that rural schooling decisions are undertaken in response to the possibility of employment in urban areas this paper tests this hypothesis using three cross sections of household data for rural india it finds that urban rates of return do influence rural schooling particularly amongst households who are most likely to seek urban employment such as the landless the results suggest that low levels of rural schooling may reflect not just conditions in the local village economy but also the functioning and size of the relevant labor market

electoral rules and corruption is corruption systematically related to electoral rules recent theoretical work suggests a positive answer but little is known about the data we try to address this lacuna by relating corruption to different features of the electoral system in a sample of about eighty democracies in the 1990s we exploit the cross country variation in the data as well as the time variation arising from recent episodes of electoral reform the evidence is consistent with the theoretical priors larger voting districts and thus lower barriers to entry are associated with less corruption whereas larger shares of candidates elected from party lists and thus less individual accountability are associated with more corruption individual accountability appears to be most strongly tied to personal ballots in plurality rule elections even though open party lists also seem to have some effect because different aspects roughly offset each other a switch from strictly proportional to strictly majoritarian elections only has a small negative effect on corruption jel e62 h3

regional returns to education child labour and schooling in india abstract we offer evidence from india that higher regional returns to primary education not only increase the likelihood that boys and girls attend school but also decrease the likelihood that they work these relationships hold only for the top three quintiles of the income distribution and mostly for children in the age group 10 14 years the former result suggests that liquidity constraints may not allow poorer households to respond to the economic benefits of education policies that raise the economic benefits of education may increase human capital investments in households that do not rely on their children s incomes for survival however low schooling and high child labour will persist among credit constrained families unless these households are provided with the economic ability to respond to these benefits

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

option values under stochastic volatility theory and empirical estimates abstract this paper numerically solves the call option valuation problem given a fairly general continuous stochastic process for return volatility statistical estimators for volatility process parameters are derived and parameter estimates are calculated for several individual stocks and indices the resulting estimated option values do not differ dramatically from black scholes values in most cases although there is some evidence that for longer maturity index options black scholes overvalues out of the money calls in relation to in the money calls

school attendance child labor and local labor market fluctuations in urban brazil abstract while the income poverty effect on child labor is long established as a main determinant of child labor there is a growing body of literature considering the pull of the labor market this paper demonstrates that after controlling for household characteristics employment rates for 14 16 year old boys and girls in urban brazil increase as local labor market opportunities improve children are also more likely to leave school as local labor market conditions become more favorable the relationship between children s schooling and work and local labor market conditions changes in years of crisis compared to other years the effects of macroeconomic fluctuations on children s school and work behavior are examined with particular focus on whether the income effect or substitution effect dominates as macroeconomic conditions change over time the study uses data from the pesquisa nacional amostra de domicilios a large household survey that is conducted almost annually by the ibge we use variation in the urban areas of 25 states over 12 years to identify the aggregate effects

partnering with leviathan the politics of innovation in foreign host state joint ventures forming international joint ventures ijvs with political institutions in emerging economies involves both benefits and risks for multinational enterprises mnes while political partners can provide ijvs with various resources their political status equips them with a strong position to appropriate rents in ijvs we address this tension by examining how host state ownership affects both innovation inputs and outputs in china based ijvs over 2008 2013 despite the potential government opportunism we find more r d investment innovation inputs made in ijvs with state partners than in those with private ones thus r d investment can be politically motivated and symbolically managed to ensure continued resource exchanges with the host state this political pressure is mitigated when foreign parents directly transfer home country based technology to ijvs when the host market dependence of ijv is weak and when ijvs are located in a deregulated region moreover we find foreign host state jvs deliver fewer innovation outputs measured by patent data than foreign private jvs which implies the failure of state partners to adequately absorb foreign technologies these findings highlight both the state partners powerfulness to boost ijv innovation investment and their limits in shaping ijv innovation outcomes and bear rich implications for the management of mne host government relationships

perspectives on positive political economy this volume serves as an introduction to the field of positive political economy and the economic and political processes with which it is concerned this new research tradition is distinct from both normative and historical approaches to political economy grounded in the rational actor methodology of microeconomics positive political economy is the study of rational decisions in a context of political and economic institutions more analytical than traditional approaches it is concerned with the derivation of principles and propositions against which real world experience may be compared its focus is on empirical regularities and its goal is theoretical explanation the field has focused on three main areas of research models of collective action constraints on competitive market processes and the analysis of transaction costs developments in all of these areas are covered in the book the first part of the volume surveys the field while the second part displays positive political economy at work examining a variety of subjects the final part contains essays by leading political economists on the theoretical foundations of the field

politics and productivity i introduction economic studies of long run performance are focusing increasingly on political legal financial and social factors development is no longer regarded as a gradual inevitable transformation from self sufficiency to specialization and participation in the division of labor instead progress follows the creation and evolution of institutions that support social and commercial relationships the new institutional economics explains that growth requires that the potential hazards of trade shirking opportunism risk and so on be controlled by institutions like secure property rights reliable procedures for resolving disputes and means of enforcing contracts in the absence of close social ties these institutions reduce information costs encourage capital formation and capital mobility allow risks to be priced and shared and otherwise facilitate cooperation north and thomas 1973 north 1990 drobak and nye 1997 levine 1997 in particular political authorities must make credible commitments not to expropriate private resources once investments have been made 1 despite widespread agreement that institutions matter there is no consensus on how they should be incorporated into the analysis even the best empirical studies of productivity and growth treat institutional characteristics in an eclectic way barro s 1991 influential article for example uses the numbers of assassinations and revolutions per capita as proxies for political instability finding these measures negatively correlated with growth and investment scully 1988 regresses growth rates on dummy variables derived from gastil s 1982 ordinal rankings of political and economic liberty king and levine 1993a 1993b 1993c derive various measures of the quality of financial intermediaries and show that these measures are good predictors of growth this article presents a different approach to analyzing the relationship between institutions and aggregate economic performance following the modem productivity literature see for example fried et al 1993 we model economic performance with a stochastic production frontier frontier analysis is a form of benchmarking it analyzes a group of branches firms nations or other units by identifying best practices and evaluating each member s performance relative to the best practice frontier the results produce not only qualitative rankings of the group members but also numerical efficiency scores that can be used to assess the effects of various policies and characteristics for this reason frontier analysis is well suited for studying the effects of legal and political institutions on the economic performance of nations to capture institutional factors we use two comprehensive indexes of legal regulatory and political conditions working with a broad sample of countries from 1975 to 1990 we incorporate a widely used measure of economic freedom along with a new measure of policy stability to represent a country s institutional environment the new institutional economics suggests that countries with high levels of economic freedom protection of private property rights respect for the rule of law an unhampered price system and so on and policy stability commitment not to change the rules of the game ex post will be closer to the best practice frontier in our model economic freedom and policy stability affect economic performance by enhancing technical efficiency in other words these institutions do not alter the state of technology but they allow producers to squeeze more out of current technology for instance countries with more stable policies attract more foreign investment than countries with less stable policies ceteris paribus this leads to increased competition among producers which in turn brings efficiency gains similarly countries with lower taxes milder regulatory burdens lower inflation fewer restrictions on foreign ownership and so on are likely to produce output more efficiently than countries with policies that restrict production inhibit capital formation and reduce competition

an economic analysis of child labor abstract this paper shows how poverty in combination with credit constraints can give rise to the phenomenon of child labor in developing countries it further shows how banning child labor can reduce the welfare of the households intending to send their children to work and suggests some alternative policies

technological change and the distribution of schooling evidence from green revolution india abstract in this paper we develop a two strata general equilibrium model of human capital acquisition with endogenous school construction that permits an assessment of the relative impacts of technological change and school availability on schooling investments in landless and landed households and illuminates how these choices interact through the adult and child labor markets the implications of the model are tested using a unique household level panel data set which constitutes a representative sample of rural india during the peak period of agricultural innovation associated with the green revolution 1968 1982 the empirical results indicate that the operation of the market for child labor worsens the distributional impact of agricultural productivity on school investment across landless and landed households as landless child labor is used to replace landed child labor lost due to increased child school attendance in landed households the results also suggest however that the allocation of school construction diminishes the adverse impact of technical change on the gap between landless and landed schooling investment

a dynamic equilibrium model of asset prices and transaction volume a dynamic general equilibrium model of capital asset pricing is constructed in which the volume of capital traded is determined endogenously the model also gives rise to a novel asset pricing formula it is shown that temporary shocks can give rise to serially correlated changes in the price of capital and transaction volume that persist long after the initial disturbance the frequency and amplitude of the resulting cycles are related to the length of the agent s planning horizon and the discount factor the model s implications for explaining asset price volatility are also explored

general equilibrium pricing of options on the market portfolio with discontinuous returns when the price process for a long lived asset is of a mixed jump diffusion type pricing of options on that asset by arbitrage is not possible if trading is allowed only in the underlaying asset and a risk less bond using a general equilibrium framework we derive and analyze option prices when the underlying asset is the market portfolio with discontinuous returns the premium for the risk of jumps and the diffusion risks forms a significant part of the prices of the options in this economy an attempted replication of call and put options by the black scholes type of trading strategies may require substantial infusion of funds when jumps occur we study the cost and risk implications of such dynamic hedging plans article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

within firm human capital externalities in tunisia this case study exploits matched firm employee tunisian data in order to underline the role played by within firm human capital in worker remuneration the estimated returns to human capital in wage equations remain unchanged when the dummies representing firm heterogeneity are replaced in the list of regressors with three firm variables a textile industry dummy within firm mean education and firm age we find that part of what is usually considered as return to education may be due to within firm externalities

valuation of american call options on dividend paying stocks empirical tests abstract this paper examines the pricing performance of the valuation equation for american call options on stocks with known dividends and compares it with two suggested approximation methods the approximation obtained by substituting the stock price net of the present value of the escrowed dividends into the black scholes model is shown to induce spurious correlation between prediction error and 1 the standard deviation of stock return 2 the degree to which the option is in the money or out of the money 3 the probability of early exercise 4 the time to expiration of the option and 5 the dividend yield of the stock a new method of examining option market efficiency is developed and tested

returns to investment in education a global update the author updates compilations of rate of return estimates to investment in education published since 1985 and discusses methodological issues surrounding those estimates some key patterns among the three main levels of education primary education continues to exhibit the highest social profitability in all world regions private returns are considerably higher than social returns because of the public subsidization of education the degree of public subsidy increases with the level of education which is regressive social and private returns at all levels generally decline by the level of a country s per capita income overall the returns to female education are higher than those to male education but at individual levels of education the pattern is more mixed the returns to the academic secondary school track are higher than the vocational track since unit cost of vocational education is much higher and the returns for those who work in the private competitive sector of the economy are higher than in the public noncompetitive sector and the returns in the self employment unregulated sector of the economy are higher than in the dependent employment sector controversies in the literature are discussed in the light of the new evidence the undisputable and universal positive correlation between education and earnings can be interpreted in many ways the causation issue on whether education really affects earnings can be answered only with experimental data generated by randomly exposing different people to various amounts of education given the fact that moral and pragmatic considerations prevent the generation of such pure data researchers have to make do with indirect inferences or natural experiments some have been attempted the author looks at the research on overeducation or surplus schooling the conclusions reinforce earlier patterns they confirm that primary education continues to be the number one investment priority in developing countries they also show that educating females is marginally more profitable than educating males that the academic secondary school curriculum is a better investment than the technical vocational tract and that the returns to education obey the same rules as investment in conventional capital that is they decline as investment is expanded
