information and time of usage decisions in the bottleneck model with stochastic capacity and demand abstract this paper analyzes the effects of information on participation and time of use decisions for a facility subject to queueing congestion when there are predictable and unpredictable fluctuations in capacity and demand with constant elasticity demand and schedule delay cost functions expected social surplus is greater with perfect than with imperfect information but imperfect information can reduce welfare by inducing adverse changes in individuals times of usage this finding has implications for the design of emerging technologies such as advanced traveller information systems that provide information about usage conditions

self organising behaviour in the presence of negative externalities a conceptual model of commuter choice abstract we use a model with local interaction a one dimensional cellular automaton to study how commuters choose among alternative roads commuters have information about their neighbours most recent experience local interaction and they remember their own experiences memory we illustrate how a simple self organizing system based on local information and locally rational agents can in some cases outperform the nash equilibrium while the social optimum is unenforceable without a central planner due to the variations in individual travel times i e the social optimum is not individually rational variations across commuters in the steady state of our self organising system are at least equivalent to and mostly significantly larger than those required for the social equilibrium increasing the neighbourhood size illustrates that more information without co ordination leads to worse overall performance

individual risk attitudes measurement determinants and behavioral consequences this paper studies risk attitudes using a large representative survey and a complementary experiment conducted with a representative subject pool in subjects homes using a question asking people about their willingness to take risks in general we find that gender age height and parental background have an economically significant impact on willingness to take risks the experiment confirms the behavioral validity of this measure using paid lottery choices turning to other questions about risk attitudes in specific contexts we find similar results on the determinants of risk attitudes and also shed light on the deeper question of stability of risk attitudes across contexts we conduct a horse race of the ability of different measures to explain risky behaviors such as holdings stocks occupational choice and smoking the question about risk taking in general generates the best all round predictor of risky behavior

clearing the air the costs and consequences of higher cafe standards and increased gasoline taxes abstract concerns about energy security and climate change have sparked legislators interest in reducing gasoline consumption by increasing corporate average fuel economy cafe standards using an empirically rich simulation model and cost estimates for anticipated fuel economy technologies we estimate annual costs of reducing long run gasoline consumption by 10 via a 3 8 miles per gallon increase in the standards and the potential cost savings from allowing manufacturers to buy and sell fuel economy credits maximum gasoline savings would be realized only after all existing vehicles were replaced or 14 years in our model a gasoline tax would produce greater immediate savings by encouraging people to drive less and eventually to choose more fuel efficient vehicles we demonstrate the advantage of a tax by comparing the cost of the higher cafe standards over the first 14 years against the cost of a gasoline tax that would save the same amount of gasoline over that time

effects of demand uncertainty on optimal capacity and congestion tolls for urban highways abstract this paper presents an analytical treatment of the effect of uncertain demand on optimal highway capacity and congestion tolls the optimal capacity under conditions of uncertainty is larger relative to the mean level of road use than the capacity appropriate for the certainty case the optimal toll may be either larger or smaller depending on its effect on the variance of equilibrium road use

nutrition and labor producvivity in agriculture estimates for rural south india using panel data for rural south india a fixed effects individual wage equation and farm production function are estimated that have calorie intake and nutritional status weight for height of workers as their arguments neither market wages nor farm output are observed to be responsive to changes in the daily energy intake of workers however both are highly elastic with respect to weight for height these results suggest that while the human body can adapt to inadequate nutrition in the short run it cannot adapt as readily to chronic malnutrition that eventually results in loss of weight for height copyright 1988 by mit press

road transport externalities during the last decade much progress has been made in defining measuring the external costs of transport as the cost of tolling equipment falls the set of realistic policy options to internalise these externalities will continue to grow this will determine the research and policy agenda we make three points firstly empirical work is still necessary to better identify marginal external costs including congestion accident and environmental costs secondly any assessment of policy options should treat externalities simultaneously the use of pricing instruments and emissions standards are discussed within this framework thirdly we emphasise the role of government designing the optimal road pricing institutions requires consideration of horizontal and vertical tax competition while double dividend arguments are central to the question of securing public support

education and freedom of choice evidence from arranged marriages in vietnam abstractusing household data from vietnam we provide evidence on the effects of education on freedom of spouse choice we use war disruptions and spatial indicators of schooling supply as instruments the point estimates indicate that a year of additional schooling reduces the probability of an arranged marriage by about 14 percentage points for an individual with eight years of schooling we also estimate bounds on the effect of education on arranged marriage when exclusion restrictions are violated locally the lower bound is six to seven percentage points the impact of education is strong for women but significantly weaker for men

stature and the standard of living research on the standard of living now emphasizes alternatives or supplements to the national income accounts this paper reviews the results of two decades of research using stature as a measure of health aspects of human welfare after comparing and contrasting stature with per capita income i consider height patterns discovered by economic historians that challenge traditional beliefs about the past including long term trends cycles in heights and the dreadfully small stature of slave children that was followed by catch up growth the paper concludes with comparisons to work in development economics and suggestions for research

optimal two part tariffs in a model of discrete choice abstract in this paper we study welfare optimal two part tariffs in a model of discrete choice the determinants of the sign and magnitude of the fixed and variable tax are analysed in terms of the nature and degree of consumer heterogeneity the price sensitivities of participation probabilities and conditional demands and the nature of distributional concerns in the absence of distributional concerns the model generalises the corrected ramsey rule for the variable tax and it shows that in the absence of collection or fixed participation costs the fixed fee may be negative the conditions that determine the sign of the participation fee turn out to have an intuitive economic interpretation finally the implications of distributional concerns for the optimal fixed and variable taxes are analysed

pricing and congestion economic principles relevant to pricing roads u k expenditures on roads or road costs average l4 34 billion per year from the 24 6 million vehicles registered road taxes of l12 7 billion were collected 2 9 times road costs from 1978 88 the average daily traffic on each km of road rose by 34 percent with a consequent serious increase in congestion road space is a valuable and scarce resource and road users should logically pay the marginal social cost if they are to make efficient transport and location decisions the paper estimates these costs and the appropriate charges for britain and identifies the major policy issues total road charges ignoring hard to quantify accident costs should yield l13 8 billion of which congestion charges would be l12 8 billion though close to road taxes in total amount replacing current taxes by road pricing would reduce congestion improve public transport and avoid perverse consequences from road expansion copyright 1990 by oxford university press

corporate combinations and common stock returns the case of joint ventures the gain to stockholders from mergers is well documented however there is little evidence as to whether the source of the gain is due to synergy or management displacement merger is just one of an almost limitless variety of ways in which firms combine resources to accomplish some objective a joint venture is another in addition to being of interest as an independent phenomenon because the original managements of the parent firms remain intact under a joint venture investigation of wealth gains from joint ventures provides an opportunity to isolate the management displacement hypothesis from the synergy hypothesis as the source of gains in corporate combinations our results are 1 there are significant wealth gains from joint ventures 2 the smaller partner earns a larger excess rate of return while the dollar gains are more equally divided and 3 the gains scaled by resources committed yield premiums similar to those in mergers we are inclined to interpret our results as supportive of the synergy hypothesis as the source of gain from corporate combinations this paper is an empirical investigation of the common stock returns of u s companies that enter into joint ventures with other u s companies we consider joint ventures in the context of what is by now a burgeoning literature examining the security returns of companies involved in intercorporate mergers and tender offers 1 in this context our objective is to provide evidence as to the source of the well documented gains to stockholders of firms involved in mergers and tender offers in addition joint ventures are an interesting economic phenomenon in their own right they are undertaken by many of the largest u s companies involve billions of dollars in capital expenditures annually and are subject to considerable scrutiny in the popular press in this regard our analysis provides data on what is as yet a relatively unexplored area of economic activity 2 a corporate merger represents the joining together of all the resources of two companies under a single management to accomplish some set of objectives empirical studies have found that mergers generally result in significant increases in the total market values of the merging firms with the stockholders of the

marginal tax reform externalities and income distribution the paper examines welfare improving and revenue neutral directions marginal policy reforms for an economy with nonidentical individuals and an externality that has a feedback effect on the consumption of taxed goods it considers three types of policy instruments the indirect taxes the uniform poll transfer and public abatement this extends the framework set up by ahmad and stern 1984 bovenberg and de mooij 1994 and schob 1996 the theoretical model is illustrated for a specific externality namely congestion caused by peak car transport

choice of foreign market entry mode impact of ownership location and internalization factors firms interested in servicing foreign markets face a difficult decision with regards to the choice of an entry mode the options available to a firm include exporting licensing joint venture and sole venture several factors that determine the choice of a specific foreign market entry mode have been identified in previous literature these factors can be classified into three categories ownership advantages of a firm location advantages of a market and internalization advantages of integrating transactions this study examines the independent and joint influences of these factors on the choice of an entry mode multinomial logistic regression model is employed to test the hypothesized effects

value of strategic alliances evidence from the bond market abstract the objective of this study is to examine the relationship between strategic alliances and the cost of debt proxied by the at issue yield spread of bond offerings we hypothesize that the participation of strategic alliances lowers a firm s cost of debt because it improves the level and stability of future profit streams and reduces information asymmetry among investors based on 2150 bond issuing firms during the period 1985 2009 we find evidence consistent with this argument furthermore we find that the mitigating effect of strategic alliances on the debt cost is much more pronounced for firms with higher product market competition more severe financial constraints and greater r d investments taken together this is the first paper to examine the importance of strategic alliances in the bond market and our results highlight that corporate alliance activity is valued outside the equity market and creates additional benefits that result in lower cost of debt financing

health economics and applications in developing countries the concept of health human capital guides the statistical study of 1 health production functions 2 derived demands for medical and behavioral health inputs and 3 determinants of health and productivity outcomes health inputs are generally endogenous to health outcomes and prices of health inputs are the most common instrumental variable for identifying estimates of the causal effects of health inputs but when health input prices are modified by individual regional migration the regional prices no longer satisfy the requirement of being independent of preferences and omitted variables then the difficulty of evaluating health program effects reinforces the need to design randomized regional treatments in order to be able to evaluate without bias the consequences of critical health interventions such as are needed today to deal with the hiv aids epidemic

local knowledge transfer and performance implications for alliance formation in asia foreign firms in host country environments frequently face location based disadvantages this study proposes three means channels of overcoming local knowledge disadvantages based on a sample of 558 japanese joint ventures jvs located in southeast and east asia we find that partnering with local firms the first channel can be a primary strategy for accessing local knowledge and improving jv performance jv experience in the host country the second channel also mitigates local knowledge disadvantages and leads to increased jv performance the third channel the foreign parent s host country experience leads to increased performance in the absence of a local partner however when a jv is formed with a local partner increased parent experience in the host country leads to decreased performance suggesting that the need for a local partner declines as parent experience in a host country increases

scale economies analysis for urban highway networks abstract extending scale economies analysis from an individual highway to an urban highway network leads to an interesting new problem when demand increases in a network establishing a new long run equilibrium may require either increasing the capacities of existing links or adding new links e g new roads interchanges overpasses this paper develops a theoretical framework for analyzing economies of scale in this setting and then uses that framework to obtain a psuedo empirical estimate of returns to scale the results suggest that mild scale economies exist in urban highway travel

partner contributions as predictors of equity share in international joint ventures the type of expertise that a company contributes to a joint venture may affect the amount of equity that it owns this research observes the ownership patterns associated with four common combinations of partner expertise in international joint ventures the results rank company assets with respect to the contributor s ability to negotiate majority ownership in the original joint venture contract and that company s tendency to buy up equity from the partner later on

disease and development the effect of life expectancy on economic growth we exploit the major international health improvements from the 1940s to estimate the effect of life expectancy on economic performance we construct predicted mortality using preintervention mortality rates from various diseases and dates of global interventions predicted mortality has a large impact on changes in life expectancy starting in 1940 but no effect before 1940 using predicted mortality as an instrument we find that a 1 percent increase in life expectancy leads to a 1 7 2 percent increase in population life expectancy has a much smaller effect on total gdp however consequently there is no evidence that the large increase in life expectancy raised income per capita

applied welfare economics with discrete choice models economists have been paying increasing attention to the study of situations in which consumers face a discrete rather than a continuous set of choices such models are potentially very important in evaluating the impact of government programs upon consumer welfare but very little has been said in general regarding the tools of applied welfare economics indiscrete choice situations this paper shows how the conventional methods of applied welfare economics can be modified to handle such cases it focuses on the computation of the excess burden of taxation and the evaluation of quality change the results are applied to stochastic utility models including the popular cases of probit and logit analysis throughout the emphasis is on providing rigorous guidelines for carrying out applied work this abstract was borrowed from another version of this item

a temporal and spatial equilibrium analysis of commuter parking abstract this paper examines the effects of parking availability on morning rush hour congestion and assesses the relative efficiency of road tolls and parking fees without pricing drivers occupy parking in order of increasing distance from the cbd a time varying toll can prevent queueing but does not affect the order in which parking spots are taken optimal location dependent parking fees may be superior they do not eliminate queueing but induce drivers to park in order of decreasing distance from the cbd thereby concentrating arrival times closer to work start times competitively set parking fees do nothing to reduce queueing and are relatively inefficient

global strategy and multinationals entry mode choice this paper makes a case directed towards establishing the importance of global strategic considerations in choosing multinationals entry mode specifically it is our contention that beyond the environmental and transaction specific factors well established in the literature to affect the entry mode decision we should also consider the strategic relationship a multinational envisages between its operations across borders in reaching this decision after incorporating various global strategic variables into an eclectic framework of the factors influencing the entry mode choice this paper tests both the validity of the overall framework and the importance of each entry mode determinant in differ entiating among entry modes this is done based on ninety six multinational managers responses to a survey questionnaire concerning their entry mode decision experiences the results suggest that an express incorporation of global strategic variables into an analysis of the entry mode decision is warranted

drinking and academic performance in high school i investigate the extent to which negative alcohol use coefficients in grade point average regressions reflect unobserved heterogeneity rather than direct effects of drinking using 2001 and 2003 youth risk behaviour survey data on high school students results illustrate that omitted factors are quite important drinking coefficient magnitudes fall substantially in regressions that control for risk and time preference mental health self esteem and consumption of other addictive substances moreover the impact of binge drinking is negligible for students who are less risk averse heavily discount the future or use other drugs however effects that remain significant after accounting for unobserved heterogeneity and are relatively large for risk averse future oriented and drug free students suggest that binge drinking might slightly worsen academic performance consistent with this the relationship between grades and drinking without binging is small and insignificant on the extensive margin and posi

wage and labor supply effects of illness in cote d ivoire and ghana instrumental variable estimates for days disabled abstract sickness should make individuals less productive but there are problems in measuring this effect first how is adult morbidity measured in a household survey second how is the impact or morbidity on productivity inferred if earning is partly used to improve health self reported functional activity limitation due to illness is considered an indicator of morbidity for wage earners and self employed people to deal with both the measurement and joint determination problems an instrumental variable estimation approach is used where local food prices and health services instrument for disability days that reduce wages by at least 10 and hours by 3 or more

optimal policies in cities with congestion and agglomeration externalities congestion tolls labor subsidies and place based strategies abstract this paper develops a spatial general equilibrium model that accommodates both congestion and agglomeration externalities while firms and households land use decisions are endogenous across continuous space focusing on the interaction between externalities and land use patterns we examine the efficiencies of first best policies and second best pricing and place based strategies using numerical simulations a first best policy must combine both pigouvian congestion tolling pct and pigouvian labor subsidies pls instruments or design an optimal toll or subsidy internalizing agglomeration externalities or congestion externalities we also examine second best pricing policies if only one instrument is adopted congestion pricing policies alone e g a partial pct or a flat rate toll can improve social welfare only in heavy congestion cities and their welfare gains may be insignificant e g below 10 of the welfare improvement achieved by first best policies in contrast second best labor subsidy policies alone are a more effective alternative to first best policies as to place based policies the firm cluster zoning fcz regulation is more efficient than the urban growth boundary ugb policy ugbs only have small effects on the agglomeration economy but could worsen land market distortions via residential rent escalation effects these findings suggest that it is important to internalize business land use decisions and relax monocentricity assumptions in order to appreciate the interplay of both urban externalities since spatial adaptations to policy interventions can distort system efficiencies

health human capital height and wages in china abstract we estimate the returns to height using data from 12 chinese cities we present both ordinary least squares ols and two stage least squares tsls estimates in the latter height is instrumented using proxies for health human capital accumulated in childhood and adolescence which influence adult height the tsls estimates are much higher reflecting the fact that the ols estimates are determined by the random genetic factors influencing height while the tsls estimates also take into account returns from investment in health human capital during childhood and adolescence these results imply considerable returns to investment in health human capital

comparing the efficiency of alternative policies for reducing traffic congestion abstract this paper compares the efficiency of a single lane toll a uniform congestion tax across freeway lanes a gasoline tax and a transit fare subsidy at reducing congestion there are three conditions for an efficient outcome relating to travel across modes across peak and off peak periods and sorting out drivers with high and low time costs across faster and slower freeway lanes each policy involves some inefficiency indeed the single lane toll gasoline tax and transit subsidy forego at least two thirds of the efficiency gains under an ideal congestion tax that varies across lanes however the uniform congestion tax achieves over 90 of these gains

information and usage of free access congestible facilities with stochastic capacity and demand we investigate the effect of information on users participation decisions at a free access congestible facility that is subject to unpredictable fluctuations in capacity and demand with demand isoelastic in user cost and user cost isoelastic in the ratio of demand to capacity optimal design capacity is larger with mean preserving spreads in capacity and demand if and only if demand elasticity is less than one expected welfare is greater with better information interestingly with nonconstant elasticity demand and or user costs information can be welfare reducing

stature skills and adult life outcomes evidence from indonesia abstractwe investigate the effect of height on earnings occupational choices and a subjective measure of wellbeing among indonesian men we explore the extent to which height captures the effects of endowments set before entry in the labour market physical and cognitive skills co determined with stature early in life do not explain much of the height earnings premium directly yet human capital more broadly including cognition educational attainment and other factors related to childhood conditions explains around half of the height premium and does so through occupational sorting indeed taller workers tend to have more education and educated workers tend to work in more lucrative occupations that require brain and social skills not brawn the unexplained share of the height earnings premium may reflect a specific role of stature on social interaction labour market advantages or self assurance we also find a height premium in happiness half of which simply accounts for the educational and e

congestion agglomeration and the structure of cities abstract congestion costs in urban areas are significant and clearly represent a negative externality nonetheless economists also recognize the production advantages of urban density in the form of positive agglomeration externalities the long run equilibrium outcomes in economies with multiple correlated but offsetting externalities have yet to be fully explored in the literature therefore i develop a spatial equilibrium model of urban structure that includes both congestion costs and agglomeration externalities i then estimate the structural parameters of the model using a computational algorithm to match the spatial distribution of employment population land use land rents and commute times in the data policy simulations based on the estimates suggest that congestion pricing may have ambiguous consequences for economic welfare

determinants of success in international strategic alliances evidence from the global aerospace industry this paper presents the results of a study linking the performance of international joint ventures and alliances set up in the global aerospace industry to their strategic and organizational features in a first stage an empirically based taxonomy of the observed alliances is generated then the economic performance of various types of alliances is evaluated on the basis of industry expert opinions and the difference in performance of different alliance types is tested

cost recovery from congestion tolls with random capacity and demand abstract according to the cost recovery theorem the revenues from congestion tolls pay for optimal capacity of a facility if user costs are homogeneous of degree zero in usage and capacity and if capacity is perfectly divisible and supplied with a unit cost elasticity this paper examines the robustness of the theorem to demand and capacity uncertainty in the context of highway travel three main results are derived 1 the theorem holds in expected values when users are perfectly informed about the state and the toll is set optimally as a function of the state 2 the theorem also holds in expected values when users are imperfectly informed about the state the toll is set optimally given the information that users have and the price elasticity of demand is the same in all states 3 the theorem does not hold if the toll is set using less information than users have whether an expected surplus or deficit results depends on the sign of the correlation across states between the pigouvian toll and the ratio of the price elasticity of demand to the price examples show that the correlation can be positive or negative depending on the functional form of the demand and cost curves and the way the curves shift between states

global connectedness and local innovation in industrial clusters in today s knowledge economy clusters are a key driver of a country s competitiveness yet a cluster s technological base is now more than ever influenced by constituent firms actions to tap into distant knowledge sources drawing on a social network perspective and distinguishing between horizontal versus vertical organization based linkages we explore the effects of a cluster s connectedness to foreign locations on its innovation performance we show that improvements in horizontal and vertical connectedness both stimulate a cluster s innovation performance but that their relative effects vary across cluster types innovation in knowledge intensive clusters disproportionately benefits from enhancements in their constituent firms horizontal connectedness to foreign knowledge hotspots innovation in labor intensive clusters mostly gains from stronger vertical connections by their firms to central value chain players abroad we discuss the implications of our findings for research on global knowledge sourcing and cluster upgrading

physiology and development why the west is taller than the rest we hypothesise that the timing of the fertility transition is an important determinant of comparative physiological development in support we provide a model of long run growth that elucidates the links between population size average body size and income during development industrialisation is shown to be accompanied by a reduction in family size and an intensification of nutrition per child early transition countries are therefore expected to be more developed today economically and physiologically empirically the timing of the fertility transition is strongly correlated with average body size across countries

role conflict and role ambiguity of chief executive officers in international joint ventures this study examines the organizational and personal correlates of role conflict and role ambiguity of chief executive officers heading international joint ventures role conflict was found to be lower when the number of parent firms was higher and when the ceo had spent more years with the organization role ambiguity was found to be lower when the ceo had more years of education when the power distance and masculinity femininity gap between parents were lower and when the individualism collectivism and uncertainty avoidance gaps were higher the implications of these findings for role theory and international management are discussed

priority service pricing investment and market organization tingent forward delivery contracts offered by a seller each customer s selection of one contract from the menu determines the customer s service order or priority in each contingency the seller rations supplies by serving customers in order of their selected priorities until the supply is exhausted or all customers are served various forms of priority service are widely

efficient and competitive rationing abstract the contracts that interest us here are called priority service contracts the salient feature of such contracts is that they specify each customer s priority in obtaining service that is they specify the tank order in which a customer is served out of the available supply until all customers are served or supply is exhausted such contracts essentially establish queues for customers in section 1 the author provides some background about priority service section 2 formulates a basic model and offer several illustrations also describes two main examples that motivate the theoretical development section 3 derives some key results that show how the prices of priority service contracts are designed to induce customers to self select efficient service orders in section 4 the author discusses various ways that state enterprises can organize markets that implement priority service efficiently in section 5 we study the operation of competitive markets for priority service section 6 concludes with some summary remarks two themes are emphasized one is that a state enterprise can promote substantial efficiency gains by substituting priority service for absent spot markets the other is that oligopolistic firms may have insufficient incentives to offer efficient product diversity consequently allocative efficiency depends on entry of numerous firms even so dispersal of supplies among many firms can prevent productive efficiency when there are advantages from pooling supplies

interfirm diversity organizational learning and longevity in global strategic alliances organizational theorists have correctly argued that the emergence and maintenance of robust cooperation between global strategic alliance partners is related to the diversity in the partners characteristics yet previous research has failed to systematically delineate the important dimensions of interfirm diversity and integrate the dimensions into a unified framework of analysis this paper develops a multilevel typology of interfirm diversity and focuses on organizational learning and adaptation as critical processes that dynamically moderate diversity s impact on alliance longevity and effectiveness

on the future of international joint venture research international joint ventures ijvs are an important type of international strategic alliance isa and have been studied by scholars for decades resulting in a plethora of empirical studies publications and reviews yet an inadequate accumulation of knowledge exists as a closer look reveals much more than providing a summary and critical assessment of past contributions this paper develops an expansive research agenda based upon a deep understanding of past research and comprehensive frameworks that distill this research we identify a number of research opportunities that would not only advance ijv research but also closely related literatures and disciplines such as isas theories of the multinational firm international business research and strategic management

theory general equilibrium and political economy in development economics i discuss the role of economic theory in empirical work in development economics with special emphasis on general equilibrium and political economy considerations i argue that economic theory plays should play a central role in formulating models estimates of which can be used for counterfactual and policy analysis i discuss why counterfactual analysis based on microdata that ignores general equilibrium and political economy issues may lead to misleading conclusions i illustrate the main arguments using examples from recent work in development economics and political economy

learning from competing partners outcomes and durations of scale and link alliances in europe north america and asia this paper investigates the outcomes and durations of strategic alliances among competing firms using alliance outcomes as indicators of learning by partner firms we show that alliance outcomes vary systematically across link and scale alliances link alliances are interfirm partnerships to which partners contribute different capabilities while scale alliances are partnerships to which partners contribute similar capabilities we find that partners are more likely to reorganize or take over link alliances than scale alliances by contrast scale alliances are more likely to continue without material changes the two types of alliances are equally likely to shut down at similar ages these results support the view that link alliances lead to greater levels of learning and capability acquisition between the partners than do scale alliances copyright 2000 john wiley sons ltd

information learning and wage rates in low income rural areas in this essay we present evidence that employers in rural areas of developing countries have imperfect information with regard to the productivity of heterogeneous workers in addition to obtaining direct measures of the completeness of employer information we consider the implications of information asymmetries for the structure of casual labor markets we then evaluate the extent to which casual labor markets do in fact exhibit these attributes we find that 1 there is adverse selection out of the time rate labor market 2 employers discriminate statistically given two workers with different observed characteristics but the same actual productivity the worker from the group with the higher average productivity will have a higher wage 3 employers exhibit learning over time the extent of employer ignorance is negatively related to labor market exposure on the part of the workers and 4 calorie consumption affects productivity but is not rewarded in the time rate labor market in concluding we argue that an analysis of wage and employment patterns and the implications of these patterns for human capital investment in rural areas of developing countries that ignored the role of information problems could yield misleading conclusions

consumer s surplus without apology the purpose of this paper is to settle the controversy surrounding consumer s surplus and by so doing to validate its use as a tool of welfare economics i will show that observed consumer s surplus can be rigorously utilized to estimate the unobservable compensating and equivalent variations the correct theoretical measures of the welfare impact of changes in prices and income on an individual i derive precise upper and lower bounds on the percentage errors of approximating the compensating and equivalent variations with consumer s surplus these bounds can be explicitly calculated from observable demand data and it is clear that in most applications the error of approximation will be very small in fact the error will often be overshadowed by the errors involved in estimating the demand curve the results in no way depend upon arguments about the constancy of the marginal utility of income consequently this paper supplies specific empirical criteria which can replace the apologetic caveats frequently employed by those who presently apply consumer s surplus moreover the results imply that consumer s surplus is usually a very good approximation to the appropriate welfare measures to preview below i establish the validity of these rules of thumb for a

does better nutrition raise farm productivity household level data from sierra leone are used to test whether higher caloric intake enhances family farm labor productivity this is the notion behind the efficiency wages hypothesis which has found only weak empirical support a farm production function is estimated accounting for the simultaneity in input and calorie choice instruments include prices household demographic characteristics and farm assets the latter two sets of instruments are later dropped to explore the robustness of the results to different specifications of exogeneity the exercise shows a highly significant effect of caloric intake on labor productivity providing solid support for the nutrition productivity hypothesis the marginal effect on productivity falls drastically as calorie consumption rises but remains positive at moderately high levels of intake one result is a fall in the effective price of food a decline that is larger for households that consumer fewer calories

random queues and risk averse users we analyse nash equilibrium in time of use of a congested facility users are risk averse with general concave utility queues are subject to varying degrees of random sorting ranging from strict queue priority to a completely random queue we define the key no residual queue property which holds when there is no queue at the time the last user arrives at the queue and prove that this property holds in equilibrium under all queueing regimes considered the no residual queue property leads to simple results concerning the equilibrium utility of users and the timing of the queue

wage gains associated with height as a form of health human capital height is consulted as a latent indicator of early nutrition and lifetime health status height is observed to increase in recent decades in populations where per capita national income has increased and public health activities have grown height is determined by genetic make up and realized in part through satisfactory nutrition and health related care and conditions alternative instrumental variables iv are explored which proxy price and income constraints which are expected to influence the latter reproducible human capital investments in height i report ols and iv estimates of the partial effect of height on log hourly wages in recent national surveys from three countries ghana brazil and the united states i conclude that the human capital productivity effect of height estimated by parent education ivs in the us and ghana are many times larger than the ols estimates and in ghana and brazil the regional price ivs estimates also imply a substantially larger human capital wage effects of height compared with the ols estimates the ols estimates of height effects on wages are dominated by the genetic variation in height and appear to understate substantially the human capital returns to health and nutrition inputs which increase adult height this abstract was borrowed from another version of this item

transport tax reform commuting and endogenous values of time abstract we consider a model of urban transport with two trip purposes commuting assumed perfectly complementary to labour supply and noncommuting to analyse the effects of transport tax reform on the value of time and marginal external congestion costs higher commuting taxes plausibly reduce time values but higher noncommuting transport prices will typically raise the value of time the intuition for this latter finding is that the reduction in congestion that follows from the tax increase itself raises net wages per hour of work inclusive of commuting time empirical illustrations with belgian data show a potentially large effect of transport tax reform on time values in quite a few of the tax reforms studied traffic levels are reduced but the increase in time values implies that marginal external congestion costs actually increase

structural estimation of congestion costs abstract we estimate a structural model of congestion costs using a bayesian nash equilibrium approach the individual s preference for traveling depends on the anticipated level of congestion which in turn is determined by travelers decisions of mobility the model is estimated using a french transportation household survey results confirm the presence of incomplete information and show that aversion to congestion is 6 6 lower during peak times than during off peak times a traveler s willingness to pay to save 1 min in traffic is estimated at 0 73 euros during peak times and 0 25 euros during off peak times

estimating a household production function heterogeneity the demand for health inputs and their effects on birth weight the household production literature emphasizes that technical or biological processes condition input selection by households in their production activities along with prices and income exogenous variations in health to the extent that they are perceived by individuals heterogeneity lead to correlations between inputs and health outcomes that cannot be used to derive causal conclusions therefore estimates of health technology must be obtained from a behavioral model in which health inputs are themselves choices consistent estimates are reported of the effect of endogenous inputs such as medical care smoking and fertility on birth weight and fetal growth in the presence of health heterogeneity

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

pareto improvements from lexus lanes the effects of pricing a portion of the lanes on congested highways abstract though economists have long advocated road pricing as an efficiency enhancing solution to traffic congestion it has rarely been implemented primarily because it is thought to create losers as well as winners this paper shows that a judiciously designed toll applied to a portion of the lanes of a highway can generate a pareto improvement before using the revenue a sufficient condition being that drivers with a high value of time travel at the peak of rush hour i obtain these new theoretical results by extending a standard dynamic congestion model to reflect an important additional traffic externality extra traffic does not simply increase travel times but also introduces frictions that reduce throughput the analysis draws attention to a practical policy that may help overcome the widespread opposition to road pricing

the value of automobile travel time implications for congestion policy abstract public policy has remained stoutly resistant to the economic profession s call to use congestion tolls to minimize the social costs from automobile congestion this paper explores this issue by using stated preference models to estimate the value that commuters are willing to pay to save travel time we find that this value is low and surprisingly insensitive to travel conditions and how toll revenues are used it appears that even high income commuters having adjusted to congestion through their modal residential workplace and departure time choices simply do not value travel time savings enough to benefit substantially from tolls

income productivity in china on the role of health this study provides empirical evidence regarding the income productivity of health human capital in china we appeal to concepts from human capital theory to support a basic model that treats health as a form of human capital in the income production process our model examines the economic return at the household level from the health of its individual members we estimate this with a longitudinal sample drawn from the china health and nutrition survey chns allowing us to exploit within variation in health and income to address possible unobservables biasing estimates of the impact of health on income in the simple cross sectional setting household income is strongly influenced by the health of its members particularly in rural areas these findings could have important implications for health and economic policy making aimed at reducing the long standing urban rural economic gap and more comprehensively insuring the rural population against health and economic risk

will a shrink make you richer gender differences in the effects of psychotherapy on labour efficiency this paper provides a first theoretical and empirical analysis of the effects of psychotherapy on individual productivity we build a simple model in which a deterioration of mental health endogenously causes a decrease in productivity which is counterbalanced by psychotherapy we test our hypotheses on the british household panel survey data we find that individuals suffering from mental health problems benefit economically from consulting a psychotherapist moreover we find that the returns are higher for men than for women even though women are more likely to seek help

the effect of population health on foreign direct investment inflows to low and middle income countries this paper investigates the effect of population health on gross inflows of foreign direct investment fdi we conduct a panel data analysis of 74 industrialized and developing countries over 1980 2000 our main finding is that gross inflows of fdi are strongly and positively influenced by population health in low and middle income countries our estimates suggest that raising life expectancy by one year increases gross fdi inflows by 9 after controlling for other relevant variables these findings are consistent with the view that health is an integral component of human capital for developing countries

war and stature growing up during the nigerian civil war the nigerian civil war of 1967 70 was precipitated by secession of the igbo dominated south eastern region to create the state of biafra it was the first civil war in africa the predecessor of many we investigate the legacies of this war four decades later using variation across ethnicity and cohort we identify significant long run impacts on human health capital individuals exposed to the war at all ages between birth and adolescence exhibit reduced adult stature and these impacts are largest in adolescence adult stature is portentous of reduced life expectancy and lower earnings

sorting by height education and economic outcomes of women in less developed countries abstracttaller height is commonly found to correlate with educational and economic outcomes most studies focus on a relationship to earnings and consider samples from individual countries this p

accounting for the effect of health on economic growth i use microeconomic estimates of the effect of health on individual outcomes to construct macroeconomic estimates of the proximate effect of health on gdp per capita i employ a variety of methods to construct estimates of the return to health which i combine with cross country and historical data on height adult survival rates and age at menarche using my preferred estimate eliminating health differences among countries would reduce the variance of log gdp per worker by 9 9 percent and reduce the ratio of gdp per worker at the 90th percentile to gdp per worker at the loth percentile from 20 5 to 17 9 while this effect is economically significant it is also substantially smaller than estimates of the effect of health on economic growth that are derived from cross country regressions

information effects in transport with stochastic capacity and uncertainty costs in this paper the impact of information provision to travelers using a model based on a stochastic equilibrium concept is analyzed a new analytical framework is proposed by including a specific term related to the costs of travel time uncertainty per se into the generalized cost function different driver information models are analyzed to assess the efficiency improving features of driver information systems compared with the optimal first best policy of road pricing the results reveal that the potential of driver information systems as an efficiency improving policy instrument are underestimated if costs of uncertainty are ignored coauthors are erik t verhoef peter nijkamp and piet rietveld copyright 1998 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

under the weather health schooling and economic consequences of early life rainfall life in rural areas of developing countries is prone to many kinds of risk such as illness or mortality of household members crop or other income loss due to natural phenomena weather insect infestations or fire for example and civil conflict in addition to their contemporaneous effects the effects of certain types of shocks may still be felt many years or even decades later from a public policy standpoint it is particularly important to identify shocks that have large long run effects moreover the mechanics underlying the persistence of shocks may be of con siderable interest for example a health shock may have a long run effect simply because the health shock itself persists over time alternately the health shock may not directly affect long run outcomes but it could affect some other outcome such as educational attainment that helps determine long run well being in this paper we focus on shocks that occur at the very beginning of life we ask how sensi tive long run individual well being is to environmental conditions around the time of birth in particular we examine the effect of weather shocks around the time of birth on the adult health education and socioeconomic outcomes of indonesian women and men born between 1953 and 1974 in addition we attempt to shed light on the intervening pathways connecting early life rainfall to adult outcomes illuminating the roles of health and educational attainment in deter mining adult socioeconomic status this investigation has considerable data requirements it necessitates information on weather shocks experienced by individuals several decades earlier as well as detailed current informa tion on adult outcomes we use information in the indonesian family life surveys ifls on an individual s year and location of birth and link each individual in that survey to locality specific rainfall data for their birth year for individuals born in rural areas on whom we focus rainfall variation across space and time should generate corresponding variation in agricultural output and thus household income to deal with measurement error in the rainfall data we run instrumental variables regressions where variables for rainfall measured at slightly more distant rainfall stations serve as instruments for rainfall in the individual s birthplace and birth year we examine the impact of early life rainfall on a range of adult outcomes observed in 2000 we find that higher early life rainfall leads to improved health schooling and socioeconomic status for women women with 20 percent higher rainfall relative to normal local rainfall in their year and location of birth are 3 8 percentage points less likely to self report poor or very poor health they attain 0 57 centimeters greater height attain 0 22 more completed grades of

effects of physical activity on earnings in the brazilian labor market abstract this article investigates the effects of physical activity on earnings in the brazilian labor market analyzing workers aged between 30 and 50 years to that end quantile regression was applied to analyze microdata from the 2008 national household sample survey pnad the results showed that workers who engage in regular physical exercise exhibit better social and economic conditions compared to sedentary individuals sedentary lifestyles are typically more common among female employees than their male counterparts and this is reflected in earnings in the labor market the impact of physical activity on wages varied from 15 0 to 31 0 and was greater among the highest quantiles the lowest salaries were recorded among non white sedentary women

the expected consumer s surplus as a welfare measure abstract the expected consumer s surplus ecs is often used as a monetary measure of consumer welfare examples include the theory of regulation competition policy and price stabilization this paper shows that in general the ecs does not convey any information about the consumer s ranking of price distributions if these differ in risk moreover the ecs provides rigorous monetary assessments of consumer welfare if and only if the consumer is risk neutral and has zero income elasticity of demand since empirical estimates suggest that these conditions are violated the paper serves as a warning to the continued use of the ecs

the incidence of congestion tolls on urban highways abstract the incidence of an optimal short run congestion toll is investigated using an equilibrium model of modal choice and congestion on a highway corridor served by express bus transit it is argued that for an externality tax the usual equi revenue analysis of burdens is inappropriate instead welfare effects are computed under three alternative assumptions about redistribution of toll revenues in almost all cases the net result is benefits for all income groups it is concluded that congestion tolls should not be rejected on grounds of income distribution but that an explicit package of tolls and revenue uses is probably a political prerequisite for adoption

economics of a bottleneck abstract drawing on vickrey amer econ rev 59 251 261 1969 and subsequent literature this paper provides a thorough economic analysis of the simplest bottleneck model of road congestion with peak load demand in the morning rush hour a fixed number of identical individuals one per car must travel from home to work between which is a bottleneck of given capacity the costs of travel include queuing time and schedule delay time early or late for work the frequency distribution of departure times adjusts so that in equilibrium all individuals have the same travel costs the paper extends the previous literature by examining a coarse toll and solving for optimal capacities the application of congestion tolls can generate efficiency gains by altering the frequency distribution of departure times previous estimates of the efficiency gains from congestion tolling are likely to be substantially downward biased because they have ignored this effect
