blurring the boundaries the interplay of gender and local communities in the commercialization of social ventures this paper examines the critical role of gender in the commercialization of social ventures we argue that cultural beliefs about what is perceived to be appropriate work for each gender influence how founders of social ventures incorporate commercial activity into their ventures specifically we argue and show that although cultural beliefs that disassociate women from commercial activity may result in female social venture founders being less likely to use commercial activity than their male counterparts these effects are moderated by cultural beliefs about gender and commercial activity within founders local communities the presence of female business owners in the same community mitigates the role of founders gender on the use of commercial activity we examine these issues through a novel sample of 584 social ventures in the united states we constructively replicate and extend these findings with a supplemental analysis of a second sample the full population of new nonprofit organizations foun

an extended production recycling model with stationary demand and return rates abstract a production recycling system is investigated a constant demand can be satisfied with production and recycling the used items are bought back and then recycled the non recycled products are disposed of two types of models will be analyzed the first model examines the eoq related costs and minimizes the relevant costs the second model generalizes the first model with the introduction of the cost function with linear waste disposal recycling production and buyback costs it is asked whether the pure either production or recycling or mixed strategies are optimal and it will be shown that under these circumstances the mixed strategies are dominated by the pure strategies the paper generalizes a former model proposed by the authors for the case of one recycling and one production batch to the case of arbitrary batch numbers

asset inequality matters an assessment of the world bank s approach to poverty reduction the fight against poverty has been adopted by the multilateral development banks as their principal objective almost three decades after robert mcnamara announced that the world bank s fundamental work was to improve the lives of the poor its new president james wolfensohn has reiterated that poverty reduction is the world bank s principal purpose similarly in 1994 the inter american development bank set social progress and social equity as its central objective the emphasis in the international institutions contrasts with disappointing results in the real world although life expectancy school enrollmuent and other indicators of social wellbeing have improved dramatically across the developing world and although the proportion of the poor has declined in the last few decades the absolute number of poor people in the world has actually increased today about 1 3 billion people in less developed countries still subsist on less than 1 per day world bank 1980 1990 1996 the case of latin america is dramatic while in the 1970 s the number of poor fell it nearly doubled in the 1980 s increasing from about 80 to almost 150 million and in the last few years the number of poor now 33 percent of the total population has failed to fall despite economic recovery birdsall and londofio 1997 the contrast between the multilateral banks goals and these disappointing results suggests the need for a critical reassessment of their approach to poverty reduction in this paper we describe the approach reflected in the work of world bank economists and based on new empirical work assess its relevance for latin america

human capital inequality and economic growth some new evidence this paper provides new measures of human capital inequality for a broad panel of countries taking attainment levels from barro and lee 2001 we compute gini coefficients and the distribution of education by quintiles for 108 countries over five year intervals from 1960 to 2000 using this new cross country data on human capital inequality two main conclusions are obtained first most countries in the world have tended to reduce the inequality in human capital distribution second human capital inequality measures provide more robust results than income inequality measures in the estimation of standard growth and investment equations

political instability and savings in less developed countries evidence from sub saharan africa a four equation model is used to investigate the effects of political instability pi on the savings rate in sub saharan africa utilising a comprehensive measure of pi we find that political instability has a deleterious effect on the savings rate both directly and indirectly through a reduction in investment and economic growth the negative effects of pi on savings rate occurs contemporaneously as well as with a lag we also find that economic growth has a stabilising effect on the political system and that not accounting for these effects through a simultaneous equations model results in biased coefficient estimates these relationships are robust with respect to model specification the implication of our results is that economic factors alone cannot explain the development process in less developed countries

life is unfair in latin america but does it matter for growth summary i analyze the effect of inequality on economic growth in latin america where inequality is measured as the area of family farms as a percentage of the total area of agricultural holdings using data from 18 latin american countries during 1960 2004 i find that inequality has a nonlinear effect on economic growth overall for the countries included in this analysis the share of family farms has a positive significant effect on economic growth these findings are robust to controlling for several factors using a different indicator of inequality land gini and addressing for endogeneity

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

why the microbrewery movement organizational dynamics of resource partitioning in the u s brewing industry1 the number of small specialty brewers in the u s beer brewing industry has increased dramatically in recent decades even as the market for beer became increasingly dominated by mass production brewing companies using the resource partitioning model of organizational ecology this article shows that these two apparently contradictory trends are fundamentally interrelated hypotheses developed here refine the way scale competition among generalist organizations is modeled and improve the theoretical development of the sociological bases for the appeal of specialist organizations products especially those related to organizational identity evidence drawn from qualitative and quantitative research provides strong support for the theory the article offers a brief discussion of the theoretical and substantive issues involved in application of the model to other industries and to other cultures

why do cooperatives emerge in a world dominated by corporations the diffusion of cooperatives in the u s bio ethanol industry 1978 2013 given the strong economic disincentives that exist why do cooperatives continue to emerge and why is it that in some communities these cooperatives are collocated with their commercial counterparts yet in others territorial partitioning occurs in this paper we develop a community ecology approach that integrates economic and sociological accounts of cooperatives in an attempt to reconcile these contradictory observations using a detailed panel data set for the county level founding process of cooperatives in the u s ethanol industry from 1978 to 2013 consistent with rational economic arguments we find that the founding rate of cooperatives decreases in the presence of high local corporate ethanol production capacity however this negative competitive interdependence is attenuated in local communities where 1 corporations represent a potential threat to the autonomy of local farmers 2 there is a generally anti corporate climate and 3 there is a well established organizational infrastructure supporting a cooperative ideology consistent with sociological theories that emphasize the mobilizing force of ideology these local conditions spur and facilitate collective action among farmers to establish cooperatives in response to the local diffusion of corporations we show further that the diffusion of plants owned by big business oil and agribusiness in communities characterized by a general anticorporate climate especially promotes greater ideological contestation and the mobilization of resources to form cooperatives

does globalization affect growth evidence from a new index of globalization the study develops an index of globalization covering its three main dimensions economic integration social integration and political integration using panel data for 123 countries in 1970 2000 it is analysed empirically whether the overall index of globalization as well as sub indexes constructed to measure the single dimensions affect economic growth as the results show globalization indeed promotes growth the dimensions most robustly related with growth refer to actual economic flows and restrictions in developed countries although less robustly information flows also promote growth whereas political integration has no effect

religious polarization and economic development abstract this paper analyzes the effect of religious diversity on economic development we argue that the religious polarization index is more appropriate to measure the effect of potential conflict on economic development than the traditional fragmentation index the empirical exercises support this view

a model of investment under uncertainty modern irrigation technology and emerging markets in water this article develops a stochastic dynamic model of irrigation technology adoption it predicts that farms will not invest in modern technologies unless the expected present value of investment exceeds the cost by a potentially large hurdle rate the article also demonstrates that contrary to common belief water markets can delay adoption the introduction of a market should induce farms with abundant scarce water supplies to adopt earlier later than they would otherwise this article was motivated by evidence that contrary to npv predictions farms wait until random events such as drought drive returns significantly above costs before investing in modern irrigation technologies copyright 2002 oxford university press

the eoq models modified by introducing discount of purchase price or increase of setup cost abstract the eoq model of inventory problem can determine ordering cycle and quantity when the purchase unit price is constant ordering cycle and ordering quantity which minimize the one day s average inventory cost is not dependent on the purchase price but if purchase price may change the eoq model must be modified the purchase unit price is discounted as the ordering becomes larger the discount of purchase price is described with a decreasing function of ordering quantity this function is not always continuous with respect to the ordering quantity under this condition one day s average profit can be defined and we can determine ordering cycle and ordering quantity which maximize one day s average profit moreover we consider the situations under which the setup cost depends on the ordering quantity in this case the setup can be described with the increasing function of ordering quantity we show that the eoq model can be applied if it is modified by introducing the continuous setup cost function this function is not differentiable at some levels of ordering quantity

farm earnings educational attainment and role of public policy some evidence from mexico abstract using real household survey data from mexico this study evaluates 1 a the impact of schooling on farm earnings through the direct and allocative effects of human capital 2 b the household demand for children s schooling 3 c using macro level data the association between children s school participation and some policy variables the overall rate of return to household heads schooling is estimated at 25 and for wives 19 the allocative effect of schooling of household heads dominates over the direct effect mother s schooling and farm size exercise significantly positive effects on household demand for schooling while in the macro model policy variables government expenditure and pupil teacher ratio appear strong determinants of children s attainment of primary schooling

optimal capacity in the anhydrous ammonia industry this study analyzed the status of manufacturing capacity in the u s anhydrous ammonia industry 1971 91 pindyck s 1988 real option model was extended to account for mean reverting tendencies in the marketing margin to determine optimal capacity for each year the key result of the study is that the 30 expansion in 1973 74 would not have been recommended by the real option model while traditional discounted cash flow approaches available in the 1970s could have easily rationalized the choices made by the industry the results underscore the potential gains in predictive power from using the real option model in analyzing large irreversible investments

returns to endogenous education the case of honduras the rapid expansion of the education sector in developing countries and the scarcity of public funds have increased the need for an accurate evaluation of educational policies estimates of rates of return to education have often been used as an integral part of cost benefit studies and programme evaluation efforts this study uses household survey data from honduras for 1990 to estimate returns to education that allow for worker heterogeneity and individual self selection in the education process a sequential estimation procedure is used that enables study of the interaction between educational attainment and earnings determination it is found that accounting for endogenous educational attainment leads to substantially higher estimated returns to education compared to traditional least squares estimates the possible magnitude of the bias underscores the importance of recognizing the role of self selection and comparative advantage in the education process

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

discount pricing decisions in distribution channels with price sensitive demand abstract in this paper we evaluate the effectiveness of quantity discounts and volume discounts as coordination mechanisms in distribution channels with demand that is price sensitive we consider a single vendor single retailer distribution channel demand for the product arises only at the retailer the demand faced by the retailer is assumed to be deterministic but price elastic the retailer in turn buys the product from the vendor the vendor and the retailer act independently and rationally each maximizing their own respective profit the equilibrium point that specifies the vendor s and buyer s inventory and pricing policy is determined by the solution to a stackelberg game we consider the cases when quantity discount and volume discount respectively are offered we develop methods to determine the optimal discount policy for these cases we then consider the case where both volume and quantity discounts are offered simultaneously and develop a method to determine the optimal simultaneous discount offer the relative performance of the alternative discount schemes is then evaluated through a numerical study the results of the study demonstrate that the effectiveness of volume discount as a coordination mechanism is higher when the sensitivity of demand to price changes is higher the effectiveness of quantity discount on the other hand is higher with lower price sensitivity of demand finally the results also demonstrate that perfect coordination is achieved when volume and quantity discounts are offered simultaneously

estimating the influence of u s ethanol policy on plant investment decisions a real options analysis with two stochastic variables abstract u s ethanol policies have contributed to changes in the levels and the volatilities of revenues and costs facing ethanol firms the implications of these policies for optimal investment behavior are investigated through an extension of the real options framework that allows for the consideration of volatility in both revenue and cost components as well as the correlation between them the effects of policy affecting plant revenues dominate the effects of those policies affecting production costs in the absence of these policies much of the recent expansionary periods would have not existed and market conditions in the late 1990s would have led to some plant closures we also show that regardless of plant size u s ethanol policy has narrowed the distance between the optimal entry and exit curves implying a more narrow range of inactivity and indicative of a more volatile evolution for the industry than would have existed otherwise

the institutional foundations of inequality and growth abstract after a decade of research the effect of inequality on long run economic growth remains unresolved in part because researchers have treated omitted variable bias as an estimation problem rather than a deeper question of causality in this article we argue that the key omitted variable is the quality of economic institutions using both cross country and panel data specifications we find no direct effect of inequality on growth in the long run rather the protection of property rights simultaneously raises growth rates and reduces income inequality we interpret these findings as evidence that insecure property rights disproportionately disadvantage the poor

policy as myth and ceremony the global spread of stock exchanges 1980 2005 we examine the antecedents and consequences in developing countries of creating a national stock exchange a core technology of financial globalization we study local conditions and global institutional pressures in the rapid spread of exchanges since the 1980s and examine how conditions at the point of adoption affected exchanges subsequent vibrancy little prior research connects the process of diffusion with the operational performance of adopted policies we find that international coercion was associated with more ceremonial adoption but that contrary to expectations common in institutional research contagion processes via peer groups and normative emulation of prestigious actors enhanced vibrancy economic globalization provides a generative context in which to consider the policy implications of organizational theory and research globalization creates both opportunities and challenges for countries on the periphery of the world economy the central question for policy makers is what structures and institutions they should adopt to promote economic and social vibrancy notably waves of alternative theories and associated packages of reforms have swept over the globe in recent decades observing this process of global diffusion and often abandonment of policies and practices meyer boli thomas and raminrez 1997 extended analyses of myth and ceremony at the organization level to the nation state in their world society approach a core idea in this work is that coercion and mimicry of peers or competitors typically based in a substrate of network ties often

a new data set measuring income inequality this article presents a new data set on inequality in the distribution of income the authors explain the criteria they applied in selecting data on gini coefficients and on individual quintile groups income shares comparison of the new data set with existing compilations reveals that the data assembled here represent an improvement in quality and a significant expansion in coverage although differences in the definition of the underlying data might still affect inter temporal and international comparability based on this new data set the authors do not find a systematic link between growth and changes in aggregate inequality they do find a strong positive relationship between growth and reduction of poverty

salaried employment and earnings in indonesia new evidence on the selection bias this article uses household survey data to estimate the determinants of earnings in indonesia a country where nonsalaried work is widespread and earnings data are available for salaried employees only we deal with the selection bias by estimating a full information maximum likelihood fiml system of equations where selection into the labour market is modelled in a multinomial setting we find that some estimated parameters of the earnings equation differ from a binomial selection procedure by heckman 1979 in particular for those variables with the strongest impact on the selection into the different labour market statuses however the estimated returns to education are unaffected even when we deal with the endogeneity of educational attainment following duflo 2001 overall our findings show that the choice of the selection rule affects the estimates of the earnings determinants in the indonesian labour market

do international migration and remittances reduce poverty in developing countries summary few studies have examined the impact of international migration and remittances on poverty in the developing world this paper fills this lacuna by constructing and analyzing a new data set on international migration remittances inequality and poverty from 71 developing countries the results show that both international migration and remittances significantly reduce the level depth and severity of poverty in the developing world after instrumenting for the possible endogeneity of international migration and controlling for various factors results suggest that on average a 10 increase in the share of international migrants in a country s population will lead to a 2 1 decline in the share of people living on less than 1 00 per person per day after instrumenting for the possible endogeneity of international remittances a similar 10 increase in per capita official international remittances will lead to a 3 5 decline in the share of people living in poverty

are economic liberalization and equality compatible evidence from south asia summary global studies of liberalization and inequality have produced divergent findings arguably because of highly heterogeneous contexts across countries and regions this paper focusing on the south asian experience with more homogeneous contexts finds that liberalization efforts and inequality grew in the region during 1980 03 data support a mutually reinforcing positive relationship in the region suggesting that liberalization helps increase inequality which in turn serves as a precondition to liberalize because economically unequal countries tend to liberalize more intensely possibly hurting the poor a lesson for concerned policymakers is to introduce policies to incrementally advance economic openness

growth inequality and poverty looking beyond averages the evidence is compelling that the poor in developing countries do typically share in the gains from rising aggregate affluence and in the losses from aggregate contraction but how much do poor people share in growth do they gain more in some settings than others do some gain while others lose does pro poor growth mean more or less aggregate growth recent theories and evidence suggest some answers but deeper microeconomic empirical work is needed on growth and distributed change only then will we have a firm basis for identifying the specific policies and programs needed to complement and possibly modify growth oriented policies

how golden parachutes unfolded diffusion and variation of a controversial practice we contribute to a growing focus on variation in diffusion processes by examining the ways in which contested practices are modified as they spread among adopters expanding on prior diffusion accounts we argue that the extensiveness and similarity of a practice will vary in response to both population and organization level mechanisms to examine these issues we study variation in golden parachute contracts a controversial corporate governance practice that emerged and spread widely during the hostile takeover wave of the 1980s using a concept network approach to analyze the composition of parachute plans we find evidence of mechanisms that both increase and decrease extensiveness and variation of golden parachutes our findings hold implications for accounts of practice diffusion over contested terrain by revealing substantial variation in the course of diffusion

poverty inequality and growth in selected middle east and north africa countries 1980 2000 abstract this paper uses crosscountry data and country case studies to analyze trends in poverty inequality and economic growth in the middle east and north africa mena region compared to other regions the mena region has a low incidence of poverty and income inequality two factors account for this situation international migration remittances and public sector government employment since the early 1980s international migration to the persian gulf and europe has helped boost the incomes of the poor in the middle east at the same time many mena countries have used government employment as a means of keeping people employed and out of poverty regression analysis of crosscountry data shows that both of these factors have a statistically significant impact on reducing the level and depth of poverty in the mena region

social business hybrids demand externalities competitive advantage and growth through diversification organization scholars have recently studied the internal challenges and opportunities faced by companies that combine business and social logics i e social business hybrids by adopting a demand side perspective this paper addresses the implications of hybridity for strategic choices with products and businesses by focusing on the role of social business hybrids customers in the conceptual framework social identity theory explains how hybridity generates both positive and negative demand side externalities thus hybridity can be a source of competitive advantage in the marketplace but also create hurdles to firms ability to scale up their business diversification represents a potential choice that simultaneously generates growth preserves hybridity and avoids negative demand side externalities this paper analyzes the optimal type timing and scope of such diversification

inequality and growth uncovering the main conclusions from the empirics abstractthis paper is a critical survey of the empirical literature on the effects of inequality on economic growth we conclude that it is most likely that the disparities found in the results are due to differences in the type of countries and time periods included in the samples the variable used to measure inequality the structure of the data and the estimation techniques these findings suggest that the mechanisms that link inequality to growth are likely to operate differently in different circumstances an element that may offer important guidelines for both policy makers and researchers

entrepreneurship in and around institutional voids a case study from bangladesh abstract in many developing countries those living in poverty are unable to participate in markets due to the weakness or complete absence of supportive institutions this study examines in microcosm such institutional voids and illustrates the activities of an entrepreneurial actor in rural bangladesh aimed at addressing them the findings enable us to better understand why institutional voids originate and to unpack institutional processes in a setting characterized by extreme resource constraints and an institutional fabric that is rich but often at odds with market development we depict the crafting of new institutional arrangements as an ongoing process of bricolage and unveil its political nature as well as its potentially negative consequences

the economic threshold with a stochastic pest population a real options approach using real options this paper formulates an optimal stopping model for applying pest control measures when the density of a pest population varies randomly a delay between successive pesticide applications is introduced to analyze the farmer s expected marginal cost of reentry this model is applied to the control of a foliar pest of apples via a pesticide and solved numerically a sensitivity analysis shows that the pest density that should trigger pesticide use can vary significantly with the pest density volatility incorporating pest randomness into simple decision rules may thus help better manage the chemicals applied to soils and crops

oppositional identities and resource partitioning distillery ownership in scotch whisky 1826 2009 we build on recent theory and research on the role of categories in resource partitioning we analyze scotch whisky making between 1826 and 2009 a case that seemed initially to fail to conform to the pattern of the beer industry now treated as prototypical on close examination both qualitative and quantitative we find that high concentration in the center of the market is not sufficient to generate a partition rather we see a long delay between the heightening of concentration in the industry and the emergence of a cluster of peripheral producers that claim an identity in opposition to the dominant generalists we explain the source of the delay as a function of the nature of the audience which until recently did not regard conglomerate or foreign ownership of distilleries as an impediment to producing authentic whisky only when critics started to question how ownership of distilleries related to authenticity did the revival of the traditional form of ownership begin to occur by analyzing entries

land inequality and economic growth a dynamic panel data approach the growing body of literature devoted to studying the impact of inequality on economic growth has centered its attention on the income distribution effect even though the theoretical relationships are more related to assets distribution while some recent studies have tried to overcome this limitation by introducing asset indicators they meet new constraints when dealing only with time invariant measurements for this explanatory variable this article provides a theoretical discussion and some novel empirical tests to better understand the relationships between assets distribution and economic growth we assembled a new panel database that includes observations for more than 30 countries over the last three decades the data include a time varying variable for changes in the land gini index over this period that enables us to overcome the limitations of previous studies a system general method of moments gmm estimator is used to generate truly unbiased and consistent estimates for the parameters of interest we explore some of the likely channels through which asset distribution and economic growth may be linked paying particular attention to the role of secure property rights and the relations between land ownership and education we find robust and significant negative signs for land inequality in the growth regressions indicating that changes in asset distribution are an important factor for economic development

educational attainment and earnings determination in colombia the expansion of the education sector in developing countries since the mid 1950s is certainly impressive between 1950 and 1980 primary and secondary enrollment ratios in many of these countries tripled or quadrupled and the educational gap with respect to developed countries narrowed although most social planners and politicians would argue that there is still a long way to go before socially optimal levels of education are attained it is also commonly acknowledged that there is an increasing need for a more careful and systematic evaluation of educational policies and by implication public funding priorities 2 although there is the question of whether all types of education should be considered equally much of the work in the evaluation process has been devoted to the production of estimates of the social and private rates of return to schooling 3 most of the early research in this area ignored the effects of educational quality heterogeneous individual abilities and other types of selection bias issues these so called first generation models produced relatively high rates of return to additional years of education from 15 to 30 depending on the country and statistical methodology employed 4 these estimates led to a form of consensus that education was a high priority item in government budget planning there is only limited evidence of how rates of return have fared subsequent to the growth of the education sector in the case of colombia however g psacharopoulos noted that the rate of return to education fell from about 20 in the early sixties to below 10 by 1979 5 during the eighties a number of second generation studies

the impact of changes in human fertility on poverty household survey data for developing and transitional economies are used to estimate the effect of fertility crude birth rate net of infant deaths on private consumption poverty cross national regressions indicate that higher fertility increases poverty both by retarding economic growth and by skewing distribution against the poor our median country in 1980 had dollar a day poverty incidence of 18 9 per cent had it reduced its fertility by four per 1 000 throughout the 1980s the sample median fall it is estimated that incidence would have been reduced to 13 9 per cent the growth and distribution effects being roughly equally responsible for this reduction

an eoq model with price dependent supply and demand abstract this paper considers a generalization of the economic order quantity eoq model for an end item that requires an input component for production the quantity of input components available for production is a nondecreasing function of the price offered by the producer to its suppliers while the end item demand is also price dependent we analyze the behavior of the optimal replenishment and pricing policy which depends on the economics of production and procurement costs and the prices associated with input components and end items this analysis sheds light on how to deal with price dependent supply in production planning as well as on the value of supplier heterogeneity and information on the relationship between component price and supply

a paradox of redistribution in international aid the determinants of poverty oriented development assistance summary donors differ in the amount of official development assistance dedicated to poverty reduction we investigate the causes of variation over time and donors by employing both a regression approach with aggregate data on bilateral aid and two short country studies on germany and the united kingdom we find that there is a trade off between the total amount of money given and the amount of money given to poor countries the trade off is similar to the paradox of redistribution of targeting vs redistribution in rich welfare states case study evidence illustrates how countries have managed this tradeoff

does financial development contribute to poverty reduction the article examines the contribution of financial development to poverty reduction in developing countries building on earlier research which has established links between financial development and economic growth and between economic growth and poverty reduction the article tests for a causal process linking financial sector growth and poverty reduction the empirical results indicate that up to a threshold level of economic development financial sector growth contributes to poverty reduction through the growth enhancing effect the impact of financial development on poverty reduction will be affected however by any change in income inequality resulting from financial development

leaving a legacy position imprints and successor turnover in young firms this article considers how local firm histories influence individual turnover rates in organizations we argue that position imprints the legacies left by the first incumbents of particular functional positions constrain subsequent position holders we show that the functional experience of the person who creates a position influences the turnover rate of successors who later occupy that position when the first position holder has an atypical background all successors experience high turnover rates individuals who are both typical with respect to the normative environment and similar to the position imprint have the lowest turnover rates surprisingly we find lower turnover rates among individuals who match the position imprint even if they violate normative expectations thus contrary to institutional theory predictions we find that local firm histories dominate in revealing how social structures emerge within firms and affect individual outcomes our research revisits core topics of bureaucratiza

joint pricing and inventory policies for make to stock products with deterministic price sensitive demand abstract in this paper we focus on a firm selling a single make to stock product to price sensitive end customers we develop an integrated operations marketing model that can help determine the relevant profit maximizing decision variable values for two pricing policies that the firm might follow price as a decision variable which is advocated by academicians and mark up pricing used by most practitioners we first consider an eoq based model with price and order quantity as independent decision variables we then develop an analogous model where price is a mark up over operating costs per unit and order quantity becomes the sole decision variable we are able to ascertain the optimal decision variable values for each model for log linear and linear demand functions we prove that for such profit maximizing models the optimal batch size is not necessarily monotone increasing in set up cost interestingly our numerical analytical evidence suggests that from a profit perspective it is better for managers to be aggressive on price rather than reducing price too much especially for highly price sensitive and non linear demand moreover we establish that in general the profit penalty for not including inventory costs in determining the optimal batch size or ignoring the batch size optimization issue in a mark up price model is not significant only when the set up cost is quite high and or the firm faces non linear demand from highly price sensitive end consumers does it become crucial for managers to determine the exact optimal batch size and base the mark up price on the entire unit operating cost not only the unit variable production cost

switching to perennial energy crops under uncertainty and costly reversibility we study a farmer s decision to convert traditional cropland into land for growing dedicated energy crops taking into account sunk conversion costs and uncertainties in crop returns the optimal decision rules differ significantly from the expected net present value rule which ignores uncertainties and from real options models that allow only one way conversion into energy crops these models also predict drastically different patterns of land conversions into and out of energy crops over time using corn soybean rotation and switchgrass as examples we show that the model predictions are sensitive to assumptions about stochastic processes of the returns government policies might have unintended consequences subsidizing conversion costs into switchgrass may not much affect proportions of land in switchgrass in the long run

inventory policies under various optimizing criteria and variable markup rates this paper extends the deterministic eoq model to reflect various optimizing criteria and alternative demand and price structures its primary purpose is to develop decision rules for the management of finished goods inventories especially in retailing where inventories are evaluated in the same way as any other investment namely on their ability to generate profits rather than on the traditional least cost basis to that effect the models developed here consider demand to be a function of price with price defined as a markup of unit cost the decision variables are the order quantity and the markup rate possible optimizing objectives include profits return on investment or residual income the three most widely used evaluators of short term investment performance optimal solutions for each case are obtained and the resulting inventory policies evaluated

ideological purity vs hybridization trade off when do islamic banks hire managers from conventional banking organizations that compete in institutional environments in which oppositional logics compete for dominance face a risk return trade off between maintaining ideological purity versus pragmatism by borrowing template elements from the rival ideology deviating from ideological purity might improve a firm s competitive strength however at the same time it might also undermine its very identity and legitimacy although such decisions are of strategic importance research about why how and where these trade offs are made is still limited we develop the argument that organizations will be more likely to deviate from ideological purity when the potential return of borrowing from the oppositional template exceeds the perceived risk of doing so the more organizations aspire to be ideologically pure the more they are constrained by the moral codes that define the category and therefore the higher the risk associated with deviating from purity however given the potential benefits of pragmatism pure or

investment decisions in hog finishing an application of the real options approach in this paper option pricing theory is applied to an investment problem in hog production a stochastic simulation model capable of pricing american type options is developed this is achieved by recursive calculation of the exercise frontier the model is used to determine the investment trigger and the disinvestment trigger for a pig fattening barn under german market conditions it turns out that the investment trigger taking into account the value of waiting in an uncertain environment can be considerably higher compared to classical investment criteria such as the net present value this offers an explanation as to why farmers are indeed reluctant to invest in hog production another finding is the sensitivity of the option prices with respect to the stochastic process that is assumed for revenues and variable costs of the production activity

economic policy changes and wage differentials in latin america abstract this article presents estimates of the impact of changes in liberalization policies on wage differentials by schooling level using a new high quality data set for 18 latin american countries for 1977 98 the method controls for all fixed and time varying country characteristics some of which may affect the policies themselves the results indicate that liberalizing policy changes overall have had a short run disequalizing effect of expanding wage differentials although this effect tends to fade away over time this disequalizing effect is due to the strong impact of domestic financial market reform capital account liberalization and tax reform however privatization contributed to narrowing wage differentials and increasing trade openness had no significant effect on wage differentials technological progress rather than trade flows appears to be a channel through which policy changes are affecting inequality

how islamic is islamic banking abstract islamic banks hold well over us 700 billion in assets and are growing at over 15 p a islamic banking and finance ibf involves wider ethical and moral issues than simply interest free transactions its advocates argue that these make it more economically efficient than conventional banking and promote greater economic equity and justice to what extent then do actual islamic banking practices live up to the ideal and how different are they from conventional banking a preliminary investigation shows that three decades after its introduction there remain substantial divergences between ibf s ideals and its practices and much of ibf still remains functionally indistinguishable from conventional banking this runs counter to claims by ibf advocates that it would rapidly differentiate itself from conventional banking however despite not providing an alternative to conventional banking and finance ibf does strengthen a distinctly islamic identity by providing the appropriate islamic terminology for de facto conventional financial transactions

the quality of schooling quantity alone is misleading although much research discusses the quantity of schooling as an effective impact on productivity and earnings most such research leaves out the idea of the quality of schooling which may cause biases in the estimated returns to schooling this paper consequently attempts to extend the standard mincerian approach to incorporate school quality as well as quantity it demonstrates how exclusion of quality in the standard procedure may cause biases in the estimated returns to years of schooling probably in the upward direction the paper explores the implications of this extension of the standard model for the case of young brazilian males it shows that the estimate of the private return to years of schooling using the preferred quality inclusive specification is only one half the estimate using the standard procedure indicating substantial upward bias in the standard estimates it further outlines a method for estimating a social return to quality and finds that it exceeds substantially the social return to quantity the paper then shows why this in turn suggests there may be an equity productivity trade off in schooling investments

changing asset endowments and smallholder participation in higher value markets evidence from certified coffee producers in nicaragua this paper examines the capacities of smallholders in nicaragua to exploit new linkages to certified coffee markets following the coffee crisis data on livelihood assets were collected from 292 households which were clustered to test how differences in outcomes asset building reflect variations in initial asset endowments the results suggest that most households built particular elements of their asset base and increased their resilience to future shocks however households struggled to make effective use of the gains for intensifying their livelihoods of the least endowed households few made investments in the scale or productivity of coffee and most continued to depend heavily on subsistence production and seasonal off farm income for survival in conclusion improved market access alone even under relatively favorable market conditions and with considerable external support will have uncertain impacts on rural poverty if the underlying constraints on household assets and investments are not addressed concurrently
