economic dynamics in the malthusian era evidence from the 1609 spanish expulsion of the moriscos we investigate economic dynamics in the malthusian era using the 1609 expulsion of moriscos from spain sharp population declines in former morisco districts were accompanied by decreased output and increased per capita output while these short run results are consistent with standard malthusian predictions malthusian convergence was delayed up to 1786 in former morisco districts archival sources and historical accounts suggest extractive institutions and cultural differences may have contributed to delayed convergence in population and output per capita this historic episode provides an unusually rich setting to examine malthusian dynamics highlighting the potential for sustained differences in per capita output in the malthusian era

rates of time preference and consumer valuations of automobile safety and fuel efficiency this article estimates hedonic price models for automobiles using a data set on almost 3 000 households from the u s department of energy residential transportation energy consumption survey the standard hedonic models are generalized to recognize the role of discounting of fuel efficiency and safety yielding an estimated rate of time preference ranging from 11 to 17 percent this range includes the prevailing rate of interest for car loans in 1988 and is consequently consistent with market rates purchasers exhibit an implicit value of life ranging from 2 6 to 3 7 million which is within the range found in the labor market as well as other market contexts the model also estimates a significant price effect for auto injury risks and fuel efficiency

measuring the damages of air pollution in the united states abstract this paper measures the damages due to emissions of air pollution in the united states an integrated assessment model is used to calculate the marginal damage associated with emitting an additional ton of pollution from nearly 10 000 sources in the u s the total damage produced by a source is the marginal damage of an emission its shadow price times the total tons emitted from a specific source adding total damages across all sources yields gross annual damages gad which is a green accounting parallel to gross domestic product gdp gad in 2002 varies between 71 billion and 277 billion 0 7 2 8 of gdp the range of values depends largely on the value of health and the concentration response function relating exposures to fine particulate matter pm 2 5 to adult mortality rates source location also matters urban emissions constitute 52 of total emissions by weight yet they cause nearly three quarters of the gad

the use and abuse of meta analysis in environmental and natural resource economics an assessment motivated by the 2006 report of a work group appointed by the environmental protection agency epa this paper examines the present state of meta analysis in environmental economics and offers recommendations for its future use to this end we summarize and assess 140 meta analyses from 125 published and unpublished studies covering 17 topical categories in environmental and resource economics first we provide several generic meta analysis models as reference points and discuss major estimation issues five econometric issues are identified as part of a complete analysis 1 sample selection criteria 2 basic data summary 3 primary data heterogeneity 4 heteroskedasticity and 5 non independence of multiple observations from primary studies second a tabular summary is presented for the 140 meta analyses with respect to estimation methods third a narrative summary is presented for 19 meta analyses including the three value of statistical life studies examined by the epa work group and one analysis from each of 16 other categories fourth we offer a set of best practice guidelines for future meta analyses in this and other areas of economics last the paper comments on the use of meta analytic methods for benefit transfers of environmental values

a limited dependent analysis of the choice of regular labour contract in seasonal agriculture the paper examines both theoretically and empirically the factors determining the demand for regular labour in seasonal agriculture in an implicit contract framework it is argued that there are hoarding costs of regular labour in the slack period when there is not much work to be done consequently the number of regular labour employed is constrained by the hoarding cost where larger employment intensive farms tend to hire more regular labour evidence from the icrisat villages in india too show that though the marginal costs of regular labour are zero there are significant hoarding costs of regular labour among small farms so that larger farmers are the major demanders of regular labour estimates of the double hurdle model jointly determining the probability of hiring regular labour and demand for regular labour hours if a regular labour is hired are shown to be an improvement over univariate tobit estimates of the demand for regular labour hours only

a generalized quantity discount pricing model to increase supplier s profits in this paper the joint problem of ordering and offering price discount by a supplier to his sole major buyer is analyzed the objective is to induce the buyer to alter his order schedule and size so that the supplier can benefit from lower set up ordering and inventory holding costs we generalize the quantity discount pricing model of monahan monahan j p 1984 a quantity discount pricing model to increase vendor profits management sci 30 6 720 726 to 1 explicitly incorporate constraints imposed on the amount of discount that can be offered and 2 relax the implicit assumption of a lot for lot or order for order policy adopted by the supplier an algorithm is developed to solve the supplier s joint ordering and price discount problem

supply chain coordination contracts with inventory level and retail price dependent demand abstract in this paper three unlike coordinating contracts namely i joint rebate contract ii wholesale price discount contract and iii cost sharing contract are proposed for two echelon supply chain coordination perspective under stock and price induced demand it is found analytically that the manufacturer s and the retailer s preferences among three contractual forms are not always aligned by applying bargaining theory it is established that stock elasticity plays an important role to select coordination contract and a threshold value stock elasticity is also determined below which cost sharing contract is not feasible it is also found that the retailer with higher bargaining power always prefers wholesale price discount contract among considered three contracts results are illustrated analytically as well as numerically

labor tying in a poor agrarian economy a theoretical and empirical analysis in this paper we show how tied labor contrary to its common characterization as a feudal relic and as a symptom of economic stagnation may actually be strengthened by capitalist agricultural development we construct a simple two period theoretical model of a two tiered labor market to show how the proportional importance of voluntary labor tying contracts may increase with yield increasing improvements and with a tightening of the labor market we then provide in support of these hypotheses some general historical as well as more detailed econometric evidence from a variety of cross sectional data in rural india

power coercion and the games landlords play abstract if an agent introduces triadic relationships through a threat when relations are dyadic without this threat and if by such a threat this agent reduces the welfare of others then this agent may be said to exercise power we construct a minimal model with three agents landlord laborer and merchant and three commodities and demonstrate that in the subgame perfect equilibrium of a finite move extensive form game of complete and perfect information there is no powerful individual we show next that in the infinitely repeated game there exists a subgame perfect equilibrium in which the landlord wields power

recruitment restrictions and labor markets evidence from the postbellum u s south this article studies the effect of recruitment restrictions on mobility and wages in the postbellum u s south i estimate the effects of criminal fines charged for enticement recruiting workers already under contract on sharecropper mobility tenancy choice and agricultural wages i find that a 13 10 increase in the enticement fine lowered the probability of a move by black sharecroppers by 12 daily wages by 1 cent 1 and the returns to experience for blacks by 0 6 per year these results are consistent with an on the job search model where the enticement fine raises the cost of recruiting an employed worker

complementarity and the measurement of individual risk tradeoffs accounting for quantity and quality of life effects this paper considers the factors responsible for differences with age in estimates of the wage compensation an individual requires to accept increased occupational fatality risk we derive a relationship between the value of a statistical life vsl and the degree of complementarity between consumption and labor supplied when health status serves as a potential source of variation in this relationship our empirical analysis finds that variations in an individual s health status or quality of life and anticipated longevity threats lead to significant differences in the estimated wage risk tradeoffs we describe how extensions to the specification of hedonic wage models including measures for quality of life and anticipated longevity threats help to explain the diversity in past studies examining how the estimated wage risk tradeoff changes with age

a quantity discount approach to supply chain coordination abstract quantity discounts provide a practical foundation for inventory coordination in supply chains however typical supply chain participants may encounter difficulties in implementing the coordination policy simply because 1 specified lot size adjustments may deviate from the economic lot sizes and 2 the buying firm may face amplified overstocking risks related to increased order quantities the main objective of this study is to develop a quantity discount model that resolves the practical challenges associated with implementing quantity discount policies for supply chain coordination between a supplier and a buyer the proposed buyer s risk adjustment b ra model allows the supplier to offer discounts that capitalize on the original economic lot sizes and share the buyer s risk of temporary overstocking under uncertain demand the analytical results suggest that the proposed b ra discount approach is a feasible alternative for supply chain coordination under uncertain demand conditions

slavery education and inequality abstract we investigate the effect of slavery on the current level of income inequality across us counties we find that a larger proportion of slaves over population in 1860 persistently increases inequality and in particular inequality across races we also show that a crucial channel of transmission from slavery to racial inequality is human capital accumulation i e current inequality is primarily influenced by slavery through the unequal educational attainment of blacks and whites finally we provide suggestive evidence that the underlying links run through the political exclusion of former slaves and the resulting negative influence on the local provision of education

the economics of labor coercion the majority of labor transactions throughout much of history and a significant fraction of such transactions in many developing countries today are coercive in the sense that force or the threat of force plays a central role in convincing workers to accept employment or its terms we propose a tractable principal agent model of coercion based on the idea that coercive activities by employers or guns affect the participation constraint of workers we show that coercion and effort are complements so that coercion increases effort but coercion always reduces utilitarian social welfare better outside options for workers reduce coercion because of the complementarity between coercion and effort workers with a better outside option exert lower effort in equilibrium and thus are coerced less greater demand for labor increases coercion because it increases equilibrium effort we investigate the interaction between outside options market prices and other economic variables by embedding the coercive principal agent relationship in a general equilibrium setup and studying when and how labor scarcity encourages coercion general market equilibrium interactions working through the price of output lead to a positive relationship between labor scarcity and coercion along the lines of ideas suggested by domar while interactions those working through the outside option lead to a negative relationship similar to ideas advanced in neo malthusian historical analyses of the decline of feudalism in net a decline in available labor increases coercion in general equilibrium if and only if its direct partial equilibrium effect is to increase the price of output by more than it increases outside options our model also suggests that markets in slaves make slaves worse off conditional on enslavement and that coercion is more viable in industries that do not require relationship specific investment by workers

compensating wage differentials with unemployment evidence from china we estimate the economic value of mortality risk in china using the compensating wage differential method we find a positive and statistically significant correlation between wages and occupational fatality risk the estimated effect is largest for unskilled workers unemployment reduces compensation for risk which suggests that some of the assumptions under which compensating wage differentials can be interpreted as measures of workers preferences for risk and income are invalid when unemployment is high workers may be unwilling to quit high risk jobs when alternative employment is difficult to obtain violating the assumption of perfect mobility or some workers e g new migrants may be poorly informed about between job differences in risk violating the assumption of perfect information these factors suggest our estimates of the value per statistical life vsl in china which range from approximately us 30 000 to us 100 000 may be biased downward alternative estimates adjust for heterogeneity of risk within industry by assuming that risk is concentrated among low skill workers these estimates which are likely to be biased downward range from us 7 000 to us 20 000

coordination and profit sharing between a manufacturer and a buyer with target profit under credit option several studies have focused on buyer vendor coordination through quantity discount credit option mechanism but few quantitative models and investigations are available that have explored the mechanism for transfer of surplus generated due to coordination in this paper we develop a coordination mechanism through credit option such that both the parties can divide the surplus equitably after satisfying their own profit targets two situations are explored here in the first situation both the parties have no individual profit target from the business whereas in the second situation there are individual profit target for both the parties the proposed mechanism for division of surplus is studied through a numerical study and the impact of different parameter values on the results are examined

do the near elderly value mortality risks differently wage hedonic models are estimated with the health and retirement study to measure the risk wage tradeoffs value of statistical lives for older workers the analysis explicitly allows for multiple employment states including retirement using a multinomial selection model the results suggest that the oldest and most risk averse workers require significantly higher not lower compensation to accept increases in job related fatality risks

why were workers whipped pain in a principal agent model one reason a person hurts another is to get that person to do something this paper uses a model to show that threatening pain can be rational and that pain is inflicted upon people who are poor in the sense of having bad alternatives the model corrects a confusion in previous models of slavery gives an explanation of why child and not adult laborers were beaten during the industrial revolution and prompts a discussion of the dangers of rational choice modeling copyright 1990 by royal economic society

endogenous enforcement institutions we model the state as a self enforcing agreement over the use of force powerful individuals punish violations of contracts and property rights and if they shirk or abuse their power society reverts to a low production anarchy stage our model has two implications first improvements in coercion move the optimal enforcement system from private ordering where coercive punishments are not used to centralized state where punihments sanction violations by citizens but not by the ruler to decentralized state where punishments sanction all violations second institutions that reinforce the allegiance of state militias to the law simultaneously insure that contract violations are punished and that the ruler does not expropriate citizens thus they are more productive than judicial institutions which solely facilitate contract enforcement the model is consistent with the historical correlation between technological advances in coercion and the transition from private to state enforcement and with the fact that institutional constraints on the executive affected the long run economic development of nations more than improvements in judicial institutions acemoglu and johnson 2005 we also provide a framework for the optimal sequencing of institutional reforms they should focus first on the binding self enforcement constraint punishment or expropriation and switch to other constraints when the initially binding constraint becomes slack

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

economic valuation of health for environmental policy comparing alternative approaches introduction and overview protecting human health is a primary goal of environmental policy and economic evaluation of health can help policy makers judge the relative worth of alternative actions economists use two distinct approaches in normatively evaluating health whereas environmental economists use benefit cost analysis supported by monetary valuation in terms of willingness to pay health economists evaluate interventions based on cost effectiveness or cost utility analysis cea using quality adjusted life years qaly or similar indexes this paper provides background on the controversy about the relative merits of these approaches and introduces the remaining papers in the special issue these papers with one exception were presented at a conference sponsored by the department of economics at the university of central florida with support from the us environmental protection agency although cea might not lead to substantially different implications for environmental policy than benefit cost analysis and qaly may provide a benefit transfer tool to fill gaps in the morbidity valuation literature the papers in this issue raise serious concerns about the suitability of qaly based cea for environmental regulatory analysis qaly does not in general appropriately represent individual preferences for health and cea is neither independent of income distribution nor adequate to assess efficiency

permanent labour and land tenancy contracts in agrarian economies an integrated analysis extending the existing models of land and labour contracts this study attempts to build a general model of long term agrarian contracts the model implies that where tenancy is an available option the fixed wage permanent labour contract will not be chosen if it is chosen under institutional constraints on tenancy contracts resulting resource allocations will be inefficient empirical relevance of the model is tested on data from the philippines

the economics of risks to life this study asks two questions 1 what is the net value to the representative individual over his life time of activities that alter age specific mortality risks 2 what is the cost to the representative individual of activities that take a life at random at a given age results derived from an economic demographic model with full age specific accounting have a strong actuarial flavor alterations in the mortality schedule caused say by a medical breakthrough should be assessed on the utility of expected additional life years production and reproduction less expected social costs of support loss of life at a specific age due to an accident say should be assessed on the opportunity costs of expected lost years of living lost production and reproduction less expected social support costs the results show that current methods in general leave out an important social transfer term that value of a life lost is highly age dependent and that the degree of diminishing returns to consumption is crucial in calculations of the economic cost of risks

labor coercion and the accumulation of human capital abstract this paper examines the effect of labor coercion on human capital accumulation we use micro data from puerto rico where unskilled laborers were forced to work for landowners during 1849 1874 using variation in municipality level suitability for coffee cultivation and international coffee prices we estimate the response of schooling to exogenous increases in relative demand for unskilled labor in regimes with and without forced labor during the coercive regime increased coffee prices had no effect on individuals literacy rates in coffee growing regions following the abolition of forced labor in 1874 similar changes in coffee prices reduced literacy rates by 12 consistent with a diminished skill premium in the free labor market regime relative to the coercive period

rural labor legislation and permanent agricultural employment in northeastern brazil abstract permanent annual or longer term agricultural employment declined relative to temporary daily weekly or seasonal employment during the 1960s in a sugar cane producing region in northeastern brazil but increased rapidly during the 1970s predictions from economic theory are combined with observations about the economic forces at work during the period to argue that in the absence of government intervention permanent employment would likely have risen during both decades the argument renders the introduction of the brazilian rural labor statute rls of 1963 a strong candidate explanation for the decline of permanent employment in the 1960s the rls s employment stability provision which required employers to make severance payments to workers with at least one year tenure dismissed without just cause not only increased the expected cost of permanent contracts but also changed the very nature of permanent employment prior to the legislation employers induced permanent workers to be subject to them by giving them premium wage and benefits packages and threatening to dismiss them if caught shirking in subjection severance pay provisions made such threats incredible the elimination of farmers ability to derive subjection benefits from permanent employees reduced even further the incentive to hire workers under permanent contracts

justifying the first order approach to principal agent problems it is of interest to know when the incentive compatibility conditio n in principal agent problems can be replaced by the condition that the agent s expected utility be stationary in effort the mirrlees rogerson conditions do not work if the principal can observe more than one observable statistic also the mirrlees rogerson assumption that the distribution function of output is convex in the agent s action is unsatisfactory even in the context of the basi c model it is too restrictive the paper presents a suite of conditio ns that are applicable to the multistatistic case and replaces the objectionable convex distribution function assumption copyright 1988 by the econometric society

estimating mortality and economic costs of particulate air pollution in developing countries the case of nigeria the value of statistical life is an essential parameter used in ascribing monetary values to the mortality costs of air pollution in health risk analyses however this willingness to pay estimate is virtually non existent for most developing countries in the absence of local estimates two major benefit transfer approaches lend themselves to the estimation of the value of statistical life the value transfer method and the meta regression analysis using nigeria as a sample country we find that the latter method is better tailored than the former for incorporating many characteristics that vary between study sites and policy sites into its benefit transfer application it is therefore likely to provide more accurate value of statistical life predictions for very low income countries employing the meta regression method we find nigeria s value of statistical life estimate to be 489 000 combining this estimate with dose response functions from the epidemiological literature it follows that if nigeria had mitigated its 2006 particulate air pollution to the world health organisation standards it could have avoided at least 58 000 premature deaths and recorded an avoided mortality related welfare loss of about 28 billion or 19 of the nation s gdp for that year

spillover health effects of energy efficiency investments quasi experimental evidence from the los angeles led streetlight program abstract payback estimates of energy efficiency investments often ignore public health externalities this is problematic in cases where spillover health effects are substantial such as when the application of new technology alters environmental exposures when health externalities are included in return on investment calculations energy efficiency programs may look more or less attractive than suggested by conventional energy savings only estimates this analysis exploits the quasi experiment provided by the 2009 los angeles la led streetlight efficiency program to investigate the returns on investments inclusive of an originally estimated health externality using the synthetic control method we find that the led streetlight program is associated with a lagged increase in breast cancer mortality of 0 479 per 100 000 inclusive of the effects of leds on breast cancer and avoided carbon emissions the la led program provides a 146 2 10 year return compared to 118 2 when health outcomes and carbon emissions are ignored

an oligopsonistic model of wage determination in agrarian societies the theory of rural wages in less developed countries is itself only partially developed three major explanations have been put forward but none of these can account for observed variations in nominal wages over time over regions and across individuals it is therefore time to take a fresh look at the problem and to develop new models which are more in accord with the data this task is undertaken in section ii where a model of heterogeneous labour is used to analyse rural labour markets and explain the wage payments system section i contains a brief summary of existing theory and its deficiencies in order to derive the main properties of the model quickly formal proofs of assertions are relegated to the technical appendix and most of the discussion of the assumptions and detailed explanations are left to section iii this section also contains general conclusions as well as a discussion of some of the more controversial issues

a two stage supply chain coordination mechanism considering price sensitive demand and quantity discounts abstract this paper explores the coordination between a supplier and a buyer within a decentralized supply chain through the use of quantity discounts in a game theoretic model within this model the players face inventory and pricing decisions we propose both cooperative and non cooperative approaches considering that the product traded experiences a price sensitive demand in the first case we study the dynamics of the game from the supplier s side as the leader in the negotiation obtaining a stackelberg equilibrium and then show how the payoff of this player could still improve from this point in the second case a cooperative model is formulated where decisions are taken simultaneously emulating a centralized firm showing the benefits of the cooperation between the players we further formulate a pricing game where the buyer is allowed to set different prices to the final customer as a reaction to the supplier s discount decisions for the latter we investigate the difference between feasibility of implementing a retail discount given a current coordination mechanism and without it finally the implications of transportation costs are analyzed in the quantity discount schedule our findings are illustrated with a numerical example showing the difference in the players payoff in each case and the optimal strategies comparing in each case our results with existing work

a supplier s optimal quantity discount policy under asymmetric information in the supply chain literature an increasing body of work studies how suppliers can use incentive schemes such as quantity discounts to influence buyers ordering behaviour thus reducing the supplier s and the total supply chain s costs various functional forms for such incentive schemes have been proposed but a critical assumption always made is that the supplier has full information about the buyer s cost structure we derive the optimal quantity discount policy under asymmetric information and compare it to the situation where the supplier has full information

export price shocks and rural labor markets the role of labor market distortions abstract to what extent can workers in developing countries seize gains from trade to answer this question we resort to a unique exogenous labor demand shock triggered by a surge in the world market price of cotton in 2010 11 by capitalizing on tajikistan s geographic variation in the suitability for cotton production we identify the effect of the export price hike on wages of rural workers the shock induces agricultural firms to shift towards labor intensive cotton production the subsequent greater labor demand doubles wages for female cotton pickers on small entrepreneurial private farms but does not affect their wages on large parastatal farms we present evidence that parastatal farms recruit workers for low wages based on monopsony power and expand employment based on labor coercion of children and public sector workers our results highlight the importance of accounting for competitive structures in local labor markets when assessing the wage pass through of world market prices to workers in developing countries

monopolizing violence and consolidating power governments in weak states often face an armed opposition and have to decide whether to try to accommodate and contain that adversary or to try to consolidate power and monopolize violence by disarming it when and why do governments choose to consolidate power and monopolize violence how fast do they try to consolidate power when does this lead to costly fighting rather than to efforts to eliminate the opposition by buying it off we study an infinite horizon model in which the government in each period decides how much to offer the opposition and the rate at which it tries to consolidate its power the opposition can accept the offer and thereby acquiesce to the government s efforts to consolidate or it can fight in an attempt to disrupt those efforts in equilibrium the government always tries to monopolize violence when it has coercive power against the opposition where roughly coercive power is the ability to weaken the opposition by lowering its payoff to fighting whether the government consolidates peacefully or through costly fighting depends on the size of any contingent spoils which are benefits that begin to accrue from an increase in economic activity resulting from the monopolization of violence and the higher level of security that comes with it when contingent spoils are small the government buys the opposition off and eliminates it as fast as is peacefully possible when contingent spoils are large the government tries to monopolize violence by defeating the opposition militarily jel codes d02 d74 h1 copyright 2013 oxford university press

performance standards and incentive pay in agency contracts when the presence of limited liability restricts a principal from imposing monetary fines on an agent in case of poor performance the principal might use other kinds of punishment threats to deter the agent from shirking we show that under the optimal contract in this case the principal sets a performance standard and punishes the agent if the standard is not met but rewards the agent on a profit sharing basis if the standard is significantly exceeded the optimal choice of performance standards for such contracts is discussed it is shown that punishment threats although inefficient often help the principal to discipline the agent jel classification d82

industrial pricing theory and managerial practice we organize the existing theoretical pricing research into a new two level framework for industrial goods pricing the first level consists of four pricing situations new product competitive product line and cost based the second level consists of the pricing strategies appropriate for a given situation for example within the new product pricing situation there are three alternative pricing strategies skim penetration and experience curve pricing there are a total of ten pricing strategies included in the framework we then identified a set of cost product market and information conditions which determine what pricing situation s a firm is facing as well as which strategies are appropriate within a given situation some of these determinant conditions are common to many pricing strategies e g highly elastic demand while others are unique to a given strategy within a particular pricing situation for example within the product line situation the profitability of supplementary sales is a unique determinant of the complementary product pricing strategy razor and blade pricing using this framework as a basis for an empirical study we examined how well current industrial pricing practice matches the prescriptions from the existing research our sample consisted of 270 respondents 27 response rate of these more than 50 indicated that they used more than one pricing strategy in formulating their most recent pricing decision for a high value industrial product sold in the united states as in previous research cost plus pricing was the most often cited pricing strategy 56 of the respondents since the respondents were able to indicate their use of more than one pricing strategy the data are of the pick k from n variety in order to model the managers pricing strategy choices we constructed a stacked binary logit with a separate observation for each strategy within a given pricing situation the signs of the determinant variables were estimated as interaction terms the new product pricing strategies skim penetration experience curve were used for new models in the market skim pricing was used in markets with high levels of product differentiation by firms at a cost disadvantage due to scale penetration pricing was used by firms with a cost advantage due to scale in markets with high level of overall elasticity but low brand elasticity experience curve pricing was used for minor innovations by firms with low capacity utilization in markets with a high level of differentiation the competitive pricing strategies leader parity and low price supplier were used in mature markets parity pricing was used by firms in a poor competitive situation i e high costs low market share low product differentiation these firms were also unable to take advantage of high levels of elasticity since their capacity utilization was high in contrast the low price supplier strategy was used by firmswith low costs due to scale advantages since they have low utilization these firms can take advantage of elastic brand demand none of the determinants were significantly related to the choice of leader pricing product line pricing strategies bundling complementary product and customer value pricing were more likely to be used by firms which sell substitute or complementary products bundle pricing was used for per sale contract pricing in markets with high levels of brand elasticity complementary product pricing razor and blade was used by firms that enjoyed high profitability on its supplementary sales using customer value pricing a firm offers a stripped down version of its current products to appeal to more price sensitive segments or to leverage new distribution channels this strategy was used to target a narrow segment in high growth markets where price changes are difficult to detect cost based pricing was more likely to be used in marketswhere demand is very difficult to estimate in such a situation cost based pricing makes a great deal of sense in general the results show that the managers pricing strategy choices are consistent with normative pricing research however questions about how managers combine their strategies to arrive at a final price as well as the organizational influences on pricing strategies remain important areas for future research

landownership concentration and the expansion of education we study the relationship between large landownership concentration and the expansion of mass education in nineteenth century prussia cross sectional estimates show a negative association between landownership concentration and enrollment rates fixed effects panel estimates indicate that regions with an initially stronger landownership concentration exhibit increasing enrollment rates this relationship is not driven by differences in the supply of schooling we argue that the implementation of agricultural reforms including the stepwise abolition of serfdom is an important driver of the change in enrollment the results are consistent with the interpretation that emancipation from labor coercion increased the private demand for education

coercive contract enforcement law and the labor market in 19th century industrial britain british master and servant law made employee contract breach a criminal offense until 1875 we develop a contracting model generating equilibrium contract breach and prosecutions then exploit exogenous changes in output prices to examine the effects of labor demand shocks on prosecutions positive shocks in the textile iron and coal industries increased prosecutions following the abolition of criminal sanctions wages differentially rose in counties that had experienced more prosecutions and wages responded more to labor demand shocks coercive contract enforcement was applied in industrial britain restricted mobility allowed workers to commit to risk sharing contracts with lower but less volatile wages

attached farm labor limited horizons and servility abstract two facets of attached farm labor arrangements the servility often required of attached laborers and employers interest in maintaining such workers limited horizons are described and incorporated into an otherwise standard model of attached and temporary agricultural employment substantially modifying the model s predictions the dependence of workers preferences on reference group behavior which underlies employers interest in limiting horizons may enable employers to drive even freely mobile workers wellbeing below competitive levels may imply that abolishing servility arrangements would benefit all workers gives rise to multiple equilibria in community layout and culture and sheds light on some characteristics of agrarian revolts

sensitivity of the eoq model to parameter estimates the economic order quantity eoq model for independent demand is well known to be somewhat insensitive to the choice of order quantity the cost goes up as the square root of the ratio of the actual order quantity to that of the optimal order quantity the question arises as to how sensitive this cost is to parameter estimates this paper extends the work by t j lowe and l b schwarz to show that under minimax and expected value criteria the sensitivity of the cost to the parameters of the model grows as the fourth root of the uncertainty in the values of the parameters furthermore for a wide class of distributions including the beta hence uniform and the gamma hence exponentials a tight bound exists for the expected error

labor market estimates of the senior discount for the value of statistical life abstract this article develops the first measures of age industry job risks to examine the age variations in the value of statistical life because of the greater risk vulnerability of older workers they face flatter wage risk gradients than younger workers which we show to be the case empirically accounting for this heterogeneity in hedonic market equilibria leads to estimates of the value of statistical life age relationship that follows an inverted u shape the estimates of the value of statistical life range from 6 4 million for younger workers to a peak of 9 0 million for those aged 35 44 and then a decline to 3 8 million for those aged 55 62 the decline of the estimated value of statistical life with age is consistent with there being some senior discount in the clear skies initiative analysis

the value of statistical life and the economics of landmine clearance in developing countries this paper presents estimates of the value of statistical life vsl in rural thailand using the contingent valuation cv method these estimates are applied to an economic analysis of landmine clearance the estimated vsl of us 250 000 suggests that the value of lives saved from landmine clearance is at least an order of magnitude greater than the values used in existing studies

why capital hires labor a bargaining perspective organizational forms often serve as vehicles for the appropriation of quasi rent capitalist firms typically emerge when production requires noncontractible investments in specific physical assets because worker control would divert quasi rents away from ass et owners ex post conversely labor managed firms tend to emerge in niches requiring specialized human capital but general purpose physi cal assets a key result is that capitalist firms can persist in competitive markets even when labor managed firms would yield a larg er total surplus copyright 1993 by american economic association

survival versus consumption we develop an indirect method to estimate utility and willingness to pay wtp for reductions in the risk of death at various ages using a life cycle model of consumption we assume that an individual sets his consumption level each year so as to maximize his expected lifetime utility alternative assumptions about opportunities for borrowing and annuities characterize two polar types of societies in our robinson crusoe case an individual must be entirely self sufficient and annuities are not available in our perfect markets case an individual can borrow against future earnings and purchase actuarially fair annuities we show that under these assumptions wtp is the sum of livelihood discounted expected future earnings and consumer surplus to illustrate our methods we derive wtp for an average financially independent american man under plausible assumptions the model is calibrated to 1978 earnings e g 18 000 per year for men aged 45 54 with at least some income in the robinson crusoe case wtp increases from 500 000 at age 20 to a peak of 1 250 000 at age 40 and declines to 630 000 at age 60 in the perfect markets case age variations are less pronounced wtp is 1 050 000 at age 20 peaks at 1 070 000 at age 25 and declines to 600 000 at age 60 these results suggest that individuals value risks to their lives at several times the pro rata share of their future earnings

a game theory approach in seller buyer supply chain in this paper several seller buyer supply chain models are proposed which incorporate both cost factors as well as elements of competition and cooperation between seller and buyer we assume that unit marketing expenditure and unit price charged by the buyer influence the demand of the product being sold the relationships between seller and buyer will be modeled by non cooperative and cooperative games respectively the non cooperative game is based on the stackelberg strategy solution concept where we consider separately the case when the seller is the leader seller stackelberg and also when the buyer is the leader buyer stackelberg pareto efficient solutions will be provided for the cooperative game model numerical examples presented in this paper including sensitivity analysis of some key parameters will compare the results between different models considered

incorporating quantity discounts to the eoq model with transportation costs abstract this article extends a previous economic order quantity eoq model with two modes of transportation namely truckload tl and less than truckload ltl carriers by introducing all units and incremental quantity discount structures into the analysis exact algorithms are developed for each quantity discount structure to compute optimal policies for single stage models over an infinite planning horizon

benefit transfer via preference calibration prudential algebra for policy this paper proposes a new approach to benefit transfer the method assumes a specific form for preferences and uses available benefit information to identify and calibrate the preference parameters to match the existing benefit estimates this approach assures economic consistency of the transfers benefit measures can never be inconsistent with household income the logic also offers a series of potentially observable predictions that can be used to gauge the plausibility of benefit transfers when multiple benefit estimates from different methods are available such as hedonic property value travel cost demand and contingent valuation the framework uses the definition of the benefit concept from each method in a single preference function to reconcile differences it provides a specific way to take account of baseline conditions and scope effects i e the size of the proposed change consistently in the transfer the method is illustrated using estimates for benefit measure changes in water quality from three studies travel cost demand hedonic property value and contingent valuation analysis q26

reputational consequences of labor coercion evidence from assam s tea plantations the right to coerce an employee is seen as advantageous to employers however if coercion gives employers a bad reputation workers may be harder to recruit we study a unique setting in assam s tea plantations in the 19th century where migrant workers were recruited under two different indentured contracts one of which was more coercive and gained notoriety in the national press and policy circles using newly collected panel data on annual migration flows to seven districts over the period 1883 1900 we find that the response of migration to increased demand for labor proxied by a rising tea price was lower for the contract that had a bad reputation workers migrated under the more coercive contract only when uninformed or misled about the terms of their employment we identify the effect of information flow by distinguishing between recruiters with and without social connections with the workers

supplier pricing and lot sizing when demand is price sensitive abstract the problem of co ordination between a vendor and a buyer is formulated as a two person fixed threat bargaining game the vendor decides on his lot size and the price schedule he is to offer to the buyer the buyer decides upon his lot size and the selling price in the market we have characterized pareto efficient solutions and the nash bargaining solution for the problem we have also proposed two pricing schedules for the vendor who is supplying to a large population of buyers the first one is based upon profit sharing the second one resembles the classical all unit quantity discount schedule we have thus provided for the supplier a procedure for setting all unit quantity discount schedule

an inquiry into quasi credit contracts the role of reciprocal credit and interlinked deals in small scale fishing communities in agrarian village societies beset with many hazards and uncertainties people evolve various means of coping with risk what is perhaps less known is that credit transactions can sometimes serve the function of reducing risk in such societies this article is concerned with examining several insurance motivated credit arrangements in small scale fishing communities a hunger insurance mechanism of reciprocal credit and a system of interlinked contracts aimed at insuring against risks in the spheres of labour and marketing relations will be extensively dealt with moreover the concept of triadic relationships will be shown to have special relevance in the case of traditional insurance arrangements aiming at controlling problems of moral hazard

targeting child labor in debt bondage despite recent multilateral efforts to single out child labor in debt bondage as one of the worst forms of child labor several important questions have yet to be addressed how pervasive is the phenomenon are there systematic correlations between the incidence of children in debt bondage and the economic legislative and financial development indicators of the economy how does an understanding of these correlates affect the way national and international policy measures aimed at targeting this form of child labor are perceived this article addresses each of these questions the empirical findings suggest strong correlation between the likelihood of the incidence of child labor in debt bondage with the stage of development of an economy the stage of financial development and enforcement of core labor rights building on this evidence the article presents a theoretical model that highlights the drawbacks and merits of a number of policies aimed at putting checks on child labor in debt bondage

the political economy of indirect control this paper characterizes the efficient sequential equilibrium when a government uses indirect control to exert its authority we develop a dynamic principal agent model in which a principal a government delegates the prevention of a disturbance such as riots protests terrorism crime or tax evasion to an agent who has an advantage in accomplishing this task our setting is a standard dynamic principal agent model with two additional features first the principal is allowed to exert direct control by intervening with an endogenously determined intensity of force which is costly to both players second the principal suffers from limited commitment using recursive methods we derive a fully analytical characterization of the likelihood intensity and duration of intervention the first main insight from our model is that repeated and costly interventions are a feature of the efficient equilibrium this is because they serve as a punishment to induce the agent into desired behavior the second main insight is a detailed analysis of a fundamental tradeoff between the intensity and duration of intervention which is driven by the principal s inability to commit finally we derive sharp predictions regarding the impact of various factors on likelihood intensity and duration of intervention we discuss these results in the context of some historical episodes

monopsony power in migrant labor markets evidence from the united arab emirates by exploiting a reform in the united arab emirates that relaxed restrictions on employer transitions we provide new estimates of the monopsony power of firms over migrant workers our results show that the reform increased incumbent migrants earnings and firm retention this occurs despite an increase in employer transitions and is driven by a fall in country exits while the outcomes of incumbents improved the reform decreased demand for new migrants and lowered their earnings these results are consistent with a model of monopsony in which firms face upward sloping labor supply curves for both new recruits in source countries and incumbent migrants

channel coordination and quantity discounts this paper presents a model for analyzing the impact of joint decision policies on channel coordination in a system consisting of a supplier and a group of homogeneous buyers the joint decision policy characterized by the unit selling price and the order quantity is coordinated through quantity discounts and franchise fees both the annual demand rate and the operating cost including the purchase ordering and inventory holding costs depend on the joint decision policy employed this paper contributes by integrating work addressing quantity discounts on inventory and ordering policies and work focusing on the control mechanism provided by quantity discounts in channel coordination it is shown that the optimal all unit quantity discount policy is equivalent to the optimal incremental quantity discount policy in achieving channel coordination furthermore it is shown that quantity discounts alone are not sufficient to guarantee joint profit maximization the analyses of the general models are illustrated by specific analytical results obtained for a given demand function
