supermarket shopping and nutritional outcomes a panel data analysis for urban kenya summary overweight and obesity are growing health problems in many developing countries rising obesity rates are the result of changes in people s diets and lifestyles income growth and urbanization are factors that contribute to these changes modernizing food retail environments may also play a certain role for instance the rapid spread of supermarkets in many developing countries could affect consumer food choices and thus nutritional outcomes however concrete evidence about the effects of supermarkets on consumer diets and nutrition is thin a few existing studies have analyzed related linkages with cross sectional survey data we add to this literature by using panel data from households and individuals in urban kenya employing panel regression models with individual fixed effects and controlling for other factors we show that shopping in supermarkets significantly increases body mass index bmi we also analyze impact pathways shopping in supermarkets contributes to higher consumption of processed and highly processed foods and lower consumption of unprocessed foods these results confirm that the retail environment affects people s food choices and nutrition however the effects depend on the types of foods offered rather than thwarting modernization in the retail sector policies that incentivize the sale of more healthy foods such as fruits and vegetables in supermarkets may be more promising to promote desirable nutritional outcomes

smallholder market participation concepts and evidence from eastern and southern africa abstract this paper reviews the evidence on smallholder market participation with a focus on staple foodgrains i e cereals in eastern and southern africa in an effort to help better identify what interventions are most likely to break smallholders out of the semi subsistence poverty trap that appears to ensnare much of rural africa the conceptual and empirical evidence suggests that interventions aimed at facilitating smallholder organization at reducing the costs of intermarket commerce and perhaps especially at improving poorer households access to improved technologies and productive assets are central to stimulating smallholder market participation and escape from semi subsistence poverty traps macroeconomic and trade policy tools appear less useful in inducing market participation by poor smallholders in the region

multiple equilibria and deterrence in airline markets we use data from the us airline industry to estimate a model of entry deterrence we model the interaction among airlines as a repeated static game where we allow for a very general form of heterogeneity we consider a menu of three alternative games that describe the strategic interaction among airlines simultaneous and sequential move games and a sequential move game with deterrence investments following bernheim 1984 deterrence investments include all investment that raises barriers to entry and for which the incumbent must incur some investment costs we show that the profits that incumbents can make in the sequential game both with and without deterrence investments are larger than those that they can make if the game is played simultaneously thus we find that on average it is profitable for all firms to deter new entrants with the exception of united airlines remarkably united airlines was under bankruptcy protection during the period of analysis suggesting that its deterrence investments were not credible overall we find that the data is explained better by a model where firms make deterrence investments thus we cannot reject the hypothesis that incumbents deter entrants in the airline industry

the food retail revolution in poor countries is it coming or is it over abstract global retail chains are becoming increasingly dominant in the global food trade and their rise leads to dramatic impacts on agricultural supply chains and on small producers however the prospects and impacts of a food retail revolution in poor countries are not yet well understood here i examine this question in madagascar a poor but stable country in which global retailers have been present for over a decade the survey and analysis find that while global retail chains sell better quality food their prices are 40 90 higher ceteris paribus than those seen in traditional retail markets in poor settings characterized by high food price elasticities a lack of willingness to pay for quality and small retail margins supermarkets appear to set prices with an eye toward maximizing profits on the basis of price inelastic demands for quality products from a small middle class interested in one stop shopping it seems unlikely that global retail chains will further increase their food reta

optimal control of a dual service rate m m 1 production inventory model we analyse a dual source production inventory model in which the processing times at a primary manufacturing resource and a second contingent resource are exponentially distributed we interpret the contingent source to be a subcontractor although it could also be overtime production we treat the inventory and contingent sourcing policies as decision variables in an analytical study and additionally allow the primary manufacturing capacity to be a decision variable in a subsequent numerical study our goal is to gain insight into the use of subcontracting as a contingent source of goods and whether it can fulfill real world managers expectations for improved performance we prove that a stationary non randomised inventory and subcontracting policy is optimal for our m m 1 dual source model and moreover that a dual base stock policy is optimal we then derive an exact closed form expression for one of the optimal base stocks which to our knowledge is the first closed form solution for a dual source model we use that closed form result to advantage in a numerical study from which we gain insight into how optimal capacity subcontracting and inventory policies are set and how effectively a contingent source can reduce total cost capacity cost and inventory cost we find that i the contingent source can reduce total cost effectively even when contingent sourcing is expensive and ii contingent sourcing reduces capacity cost more effectively than it does inventory cost

market performance in an open developing economy technical and allocative efficiencies of korean industries this paper first examines determinants of technical efficiency in terms of competition and government regulation including protection in korean industries relying heavily upon the concepts of x efficiency and rentseeking activities allocative efficiency measured as profitability is then considered with technical efficiency as a determinant the outcome of the regression shows that both the sheltering of industries from international competition and the financial market distortions strongly affect technical efficiency and that technical efficiency as well as effective protection rate are important determinants of profitability

labour chains analysing the role of labour contractors in global production networks abstract third party labour contractors are increasingly prevalent in global production networks gpns and can provide a channel for new forms of unfree labour review of case study evidence from south african and uk horticulture suggests this often emerges off site through labour intermediaries analytical approaches to labour in gpns and value chains are examined the article argues that labour contracting is driven by the commercial dynamics of global outsourcing a cascade system allows unscrupulous intermediaries to coerce vulnerable workers we examine strategies of civil society alliances and regulatory reform and argue for extending liability of all commercial actors across global boundaries

excess capacity as a policing device abstract a great deal of recent work has been devoted to the question of whether an incumbent firm can successfully deter entry by investing in excess capacity this paper demonstrates that a dominant firm may invest in excess capacity even when it is certain that this will not deter entry rather the excess capacity is held by the dominant firm in order to ensure that its competitors will exercise appropriate restraint in their own output decisions an example is provided that illustrates that the rate of return on the capital invested in excess capacity may be very high

agroindustrialization globalization and international development an overview of issues patterns and determinants this paper offers an overview for a special issue on agroindustrialization globalization and international development it sets out a conceptual framework for understanding the links among these three broad phenomena and then discusses emerging issues and evidence concerning the factors conditioning agroindustrialization in developing countries and the subsequent effects on employment poverty and the natural environment we conclude with a research agenda

economies of scale and barriers to entry dixit has recently presented a model in which established firms select capacity to discourage entry but cannot employ threats they would not rationally execute after entry entry deterrence in a slight modification of this model involves the classical limit price output under linear or concave demand however the capital cost of a firm of minimum efficient scale is an upper bound on the present value of the monopoly profit stream that can be shielded from entry it is argued that this suggests the general unimportance of entry barriers erected by scale economies

nutrition agriculture and the global food system in low and middle income countries the entire food value chain and diet of low and middle income countries lmics are rapidly shifting many of the issues addressed by the nutrition community ignore some of the major underlying shifts in purchases of consumer packaged foods and beverages at the same time the drivers of the food system at the farm level might be changing there is a need for the agriculture and nutrition communities to understand these changes and focus on some of their implications for health this rapid growth of the retail sector will change the diets of the food insecure as much as that of the food secure across rural and urban lmic s this short commentary contents that current research programs and policies are ignoring these rapid dynamic shifts

the hidden middle the quiet revolution in the midstream of agrifood value chains in developing countries the food security debate has focused largely on the farm sector and on trade relatively neglected or hidden from mainstream debate are the middle segments processing logistics wholesale of agrifood value chains in developing countries and yet this midstream forms 30 40 per cent of the value added and costs in food value chains the productivity of the midstream is as important as farm yields for food security in poor countries the article shows that over the past several decades the middle segments have transformed quickly and surprisingly with a huge volume expansion a proliferation of small and medium enterprises smes but also concentrating and multinationalizing in some places and products with technology change characterized by capital led intensification and with the incipient emergence of branding and labelling and packaging of new organizational arrangements in procurement and marketing interfaces with farmers and retailers and of private standards and contracts economic policies of market and foreign direct investment fdi liberalization commercial and business climate regulations hard and soft infrastructure investment and food safety laws have paved the path to the expansion and shaped the transformation of the important midstream segment of food value chains

private agri food standards implications for food policy and the agri food system abstract this paper provides a brief introduction to the evolution and nature of private food safety and quality standards highlighting the resultant impacts on the structure and modus operandi of supply chains for agricultural and food products and the challenges posed for processes of agricultural development it serves as an introduction to a series of papers that provide a comprehensive overview of the current state of knowledge regarding private food safety and quality standards in both an industrialised and developing country context in so doing it aims to provide a catalyst for further research on this rapidly evolving field of inquiry

a dynamic model of advertising and market shares this paper presents a model of strategic advertising and the battle for market shares between incumbents and entrants the lagged impact of advertising allows incumbents strategically to use preentry advertising to effect the postentry equilibrium solution however because the advantages to advertising are erodable by counter persuasive advertising strategies of entrants the threat of entry may cause incumbents to take retreative or aggressive strategies the incumbants retreative or aggressive posture depends crucially on the erosion impact on their advertising

rural infrastructure transactions costs and market participation in kenya abstract we develop a conceptual framework for quantifying fixed transactions costs facing semisubsistence households using household survey data from a sample of 324 kenyan maize farmers we jointly estimate household supply and demand schedules and transactions costs econometric results indicate that on average the ad valorem tax equivalent of fixed transactions costs for households in our sample is 15 additional analysis indicates that economic isolation is positively associated with the size of transactions costs to the best of our knowledge ours are the first empirical estimates of the magnitude of fixed transactions costs for agricultural households in developing countries

the political economy of regulations and trade wine trade 1860 1970 dramatic changes in the 1860 1970 wine trade provide insights on the political economy of regulations and policy instrument choice and trade an invasion of phylloxera in the 1870s turned france from the world s leading exporter to a massive importer of wine and grapes when french production recovered a combination of tariffs safety regulations and quality standards were introduced to protect its french producers causing dramatic changes in global wine and grape production and trade including in spain italy turkey greece algeria tunisia and morocco changes in wine regulations were caused by relative income and loss aversion factors in political economy tariffs were the preferred policy instruments as they directly restrict imports bring in revenues have low transaction costs and are preferred political instruments when there are information imperfections safety regulations and quality standards including labelling and input prohibitions reduce asymmetric information for consumers or undesirable externalities and simultaneously protected domestic producers regulations were often targeted at imported products wine and raisins when tariffs were ineffective or constrained by institutions such as on colonial wine hence tariffs and quality regulations were jointly used in wine policy both as complements and as substitutes in policy design

sunk costs and strategic commitment a proposed three stage equilibrium dixit s i980 paper in this journal the role of investment in entry deterrence has attracted considerable interest from economists concerned with constructing a modern theory of strategic behaviour towards entry in fact the paper has spawned quite an industry of commitment models in which the equilibrium payoffs in some final period game can be influenced by strategic commitments made by the players in an earlier period for similar models with important insights into strategic entry deterrence see eaton and lipsey i980 i98i schmalensee i98i the purpose of this note is to argue that when the instrument of stragetic commitment takes the form of sunk costs which both entrant and incumbent have to bear as it does in dixit s paper and in many other examples a three stage model rather than the two stage model presented by dixit is required although the proposed equilibrium differs from dixit s its qualitative features are the same it may or may not be profitable to deter entry and if it is the first mover may still prefer to play an accommodation strategy and allow entry to take place following dixit we restrict our attention to the asymmetric case in which one firm the incumbent makes the first move the two stage game involves the first mover sinking part of its costs in advance so that in the second stage equilibrium it will have a current cost advantage over the entrant which must incur the full cost of producing any desired output level the second period cost asymmetry ensures the incumbent a lar ger share of the post entry market which may be sufficient to deter entry altogether the problem with the two stage game lies in the nature of sunk costs sunk costs by definition are committed before the production period takes place if they were expended as a flow simultaneously with production they would not be sunk the installation of capacity is the natural example employed by dixit and well illustrates the point if installed capacity is a sunk cost which it must be for the incumbent to acquire any strategic advantage at all then the entrant s installed capacity is equally sunk and must also be committed before the production period takes place given this observation the post entry final period equilibrium should not be modelled as if the entrant were simultaneously incurring both variable and sunk costs but the incumbent only incurs variable costs this implies too great an asymmetry in favour of the incumbent the final period equilibrium should involve both firms incurring only variable

an analysis of childhood malnutrition in rural india role of gender income and other household characteristics there are controversies regarding the role of individual and household characteristics in childhood nutritional status measured by anthropometric indicators using a nutrition index based on weight for age of children in rural india the paper re examines this issue ordered probit estimates of nutritional status suggest female literacy improves the nutritional status of boys at the cost of girls while higher per capita current income improves that of both boys and girls though the impact is higher for boys however effect of income is not robust when we use instruments of longer run income but more income and literacy give more ways to discriminate between boys and girls

resource allocation in a few industries determinants and trends when the major corporations divisionalised their organisation after the second world war they devised a performance measurement system to monitor the development of their business units and a capital budgeting system to control the direction of investments the appraisal of investments was decentralised and capital budgeting became a bottom up process standardised through written routines and supervised via a pre approval control system since then investments in training rd indeed it rarely exists in professional service groups notwithstanding the industry does not invest less but concentrates on intangible types of investments the purpose of this article is to describe and identify the factors which dictate the design of the resource allocation system in a few industries and thereby perceive the direction in which the development is heading the analysis identifies five factors which determine the design of the resource allocation system and shows how this affects the resource allocation system in six industries it also discusses different means of control and the future trends and explains why the capital budgeting system becomes less important as industry becomes more knowledge intensive

small farmers and big retail trade offs of supplying supermarkets in nicaragua summary in nicaragua and elsewhere in central america small scale farmers are weighing the risks of entering into contracts with supermarket chains we use unique data from cooperatives supplying supermarkets to study the effect of supply agreements on producers mean output prices and price stability we find that prices paid by the domestic retail chain approximate the traditional market in mean and variance while mean prices paid by walmart are significantly lower than the traditional market however the walmart contract is found to systematically reduce price volatility we find some evidence however that farmers may be paying too much for this contractual insurance against price variation

spillovers from modern supply chains to traditional markets product innovation and adoption by smallholders there is an emerging body of literature analyzing how smallholder farmers in developing countries can benefit from modern supply chains however most of the available studies concentrate on export markets and fail to capture spillover effects that modern supply chains may have on local markets here we analyze the case of sweet pepper in thailand which was initially introduced as a product innovation in modern supply chains but which is now widely traded also in more traditional markets using survey data from smallholder farmers and econometric techniques we show that sweet pepper cultivation contributes significantly to higher household incomes strikingly at this stage participation in modern supply chains does not lead to higher incomes than supplying sweet pepper to traditional markets however the results also indicate that missing land titles weak infrastructure conditions and limited access to information constituted serious constraints during the early phases of sweet pepper adoption such constraints need to be overcome so that smallholder farmers are better prepared for the prompt reactions needed under rapidly changing market conditions

defensive marketing strategies this paper analyzes how a firm should adjust its marketing expenditures and its price to defend its position in an existing market from attack by a competitive new product our focus is to provide usable managerial recommendations on the strategy of response in particular we show that if products can be represented by their position in a multiattribute space consumers are heterogeneous and maximize utility and awareness advertising and distribution can be summarized by response functions then for the profit maximizing firm it is optimal to decrease awareness advertising it is optimal to decrease the distribution budget unless the new product can be kept out of the market a price increase may be optimal and even under the optimal strategy profits decrease as a result of the competitive new product furthermore if the consumer tastes are uniformly distributed across the spectrum a price decrease increases defensive profits it is optimal at the margin to improve product quality in the direction of the defending product s strength and it is optimal at the margin to reposition by advertising in the same direction in addition we provide practical procedures to estimate 1 the distribution of consumer tastes and 2 the position of the new product in perceptual space from sales data and knowledge of the percent of consumers who are aware of the new product and find it available competitive diagnostics such as the angle of attack are introduced to help the defending manager this article was originally published in marketing science volume 2 issue 4 pages 319 360 in 1983

investment in lumpy capacity abstract investment in lumpy capacity is usually fraught with uncertainty divergent opinions about the future can then lead to adverse selection optimistic competitions tend to be the ones that expand few firms correct this bias formally they rely instead on payback criteria portfolio planning risk sharing and self restraint

entry deterrence with uncertain entry and uncertain observability of commitment the standard approach to the issue of strategic entry deterrence is based on the assumption that if the incumbent does not precommit entry will take place with certainty while if he does precommit entry will be deterred with certainty in this note we allow for the possibility that the opportunity cost of entry is random so that entry is not a priori certain we also allow for the possibility that the incumbent s commitment is not observed by the potential entrant we show in numerical examples that even very little uncertainty may be sufficient to induce the incumbent not to attempt to deter entry

resource allocation to defensive marketing and manufacturing strategies abstract in this paper we investigate the coordinated use of marketing and manufacturing strategies to formulate a defensive business strategy for an incumbent firm upon market entry while defensive marketing strategies have been researched extensively little has been done on defensive manufacturing strategies and even less on coordinating these two we propose a formulation for the joint formation of a defensive strategy by the marketing and production functions under budget constraint considerations the incumbent firm may allocate its resourcesto advertising and distribution expenditures as well as to manufacturing investments to reduce the unit production cost the incumbent firm has also the option of simply allocating all of its resources purely to advertising and distribution we show that while there exist cases where the optimal reaction to entry involves investments in manufacturing improvements there are also cases where defense is in marketing strategies alone we identify the market conditions that promote such reactions to entry and also provide sensitivity analysis

entrepreneurial strategy and the presence of small firms a model is presented hypothesizing that the level of small firm presence in any given industry emanates from the exogenous stock of entrepreneurial talent a stochastic element of managerial and entrepreneurial talent entry deterrence and the entrepreneurial strategy deployed by small firms using data newly released by the u s small business administration the hypothesis is tested for a sample of 247 four digit standard industrial classification industries spanning the entire spectrum of firm sizes we find that consistently for all the measures of small firm size and for all of the time periods used the existence of entry deterrence and reliance upon innovative strategy explains a significant proportion of the variation in the presence of small firms

urban household demand for fresh fruits and vegetables in thailand 300 200 2550 abstract food systems are undergoing profound changes in developing countries particularly on fresh produce with specific quality and safety attributes an understanding of the demandpatterns and their underlying determinants are important in designing food policies and generating information for local supply actors the disaggregate demand parameters for fresh fruits vegetables that have different product and process attributes were estimated by using the two stage budgeting framework the methodology accounted for censored data the analysis is based on crosssectional data of 300 households in bangkok and 200 households in urban areas of chiang mai in 2007 the trend in domestic demand for fresh fruits vegetables is towards an emphasis on safety quality and convenience economic development along with higher household incomes and educational levels of consumers contribute to this tendency households are becoming more price responsive to fresh produce from modern supply chain sectors the entire food sector should adapt to changes in consumers preferences traditional retailers should create customer trust by adopting safety and quality standards and upgrading the quality attributes of fresh produce modern retailers should sustain own reputation and improve product lines by adopting premium standards policies and programs that foster income growth along with better education will spur demand for better quality products and lead to diversification in diets the government should encourage the development and adoption of credible standards and product and process certification schemes an information campaign to educate consumers on food safety and quality would expand the market for fresh produce and benefit farmers keywords fruit vegetable demand elasticity food safety almost ideal demand system

spatial competition and price leadership in the stackelberg price leader price follower model each firm is typically better off as a follower than as a leader in this paper we show that introducing the spatial dimension provides a means of endogenising the role of price leadership furthermore the leader follower framework yields existence of a price and location equilibrium in the hotelling spatial model of competition where none exists under the original specification we first analyse the original hotelling model by determining reaction functions for firms this approach allows the model to be fully characterised and affords an intuitive explanation of the non existence of a price equilibrium for certain locations the reaction functions are then used to determine the solution when one firm adopts the stackelberg leadership role contrary to the existing predictions of the simple spatial duopoly model it is found that the outcome is asymmetric in terms of stackelberg equilibrium locations prices and profits with the first firm in the market enjoying higher profits than the subsequent entrant the equilibrium involves one firm locating at the mid point of the market this outcome is also appealing as it corresponds to the entry deterring and monopoly solutions

advertising and economies of scale critical comments on the evidence the general issue to be discussed in this review article is does the advertising cost per dollar of sales increase as increases in total advertising expenditures occur stated in this fashion however the question of economies of scale and increasing returns to advertising is vague and equivocal the difficulty of formulating the question in a rigorous enough fashion is the root cause of much of the controversy and confusion about the efficiency of advertising at various levels of advertising expenditures or other forms of advertising input regardless of the formidable theoretical and methodological problems involved the economies of scale in advertising remain an important issue more often than not antitrust measures and public regulation of the marketplace are based on or legitimized by assumptions of substantial scale economies enabling established large corporations to maintain market power keeping competitors out and prices up the purpose of this article is critically to review the most important empirical evidence relating to economies of scale in advertising the article

excess capacity and entry some empirical evidence recent articles by spence i977 dixit i979 and schmalensee i98i have elaborated on wenders i97i1 proposition that excess capacity can act as a barrier to entry the intent of all of these treatments is to suggest that firms may rationally invest in excess capacity with the expectation that excess capacity will be seen by potential entrants either as a signal of aggressive intent or as a credible threat 2 when excess capacity does not lead to creation of a credible threat it may still act as a barrier to entry by shifting the risk return perceptions of potential entrants enough to divert the potential entrants investments into other industries 3 alternatively investment in excess capacity by incumbent firms may reduce the prospects of an active market for the used equipment of a defunct entrant and thereby help to convert fixed costs into sunk costs consequently raising entry barriers 4 this paper represents an exploratory effort to investigate empirically the prevalence and efficiency of excess capacity in deterring entry first a simple and traditional model of entry is presented this is followed by the description of the data used to explore the excess capacity investment concept a combined results and comments section follows the description of the data

managing food price risks and instability in a liberalizing market environment overview and policy options abstract managing food price risks and instability is a major challenge in the midst of ongoing food market reforms key findings from the papers in this special volume revolve around five broad areas i the sources and magnitudes of food price instability in different country contexts ii the economic and social costs stemming from price instability iii the lessons from food market reforms to date iv the design of policy reforms in ways that promote efficient and stable market development and protect the interests of the poor and v potential policy responses to food price instability in a liberalizing market environment

impact of contract farming on income linking small farmers packers and supermarkets in china summary this study compares contract and non contract growers of apples and green onions in shandong province china in order to explore the constraints on participation and the impact of contract farming on income we find little evidence that firms prefer to work with larger farms though all farms in the area are quite small using a heckman selection correction model we find that contract farming raises income even after controlling for observable and unobservable household characteristics these results suggest that contract farming can help raise small farm income though questions remain regarding the number of farmers that can be brought into such schemes 2009 elsevier ltd all rights reserved

capital as a commitment strategic investment to deter mobility abstract this paper analyzes how an early entrant in a market can exploit its head start by strategic investment the analysis is based on spence s paper investment strategy and growth in a new market bell j econ 10 1979 1 19 we frist study the investment game in the no discounting case which embodies the key features of mobility deterrence we establish the existence of a set of perfect equilibria and suggest that one particular equilibrium is most reasonable this equilibrium also valid with discounting involves the follower firm being forever deterred from investing to its steady state reaction curve in contrast to spence s proposed solution

investments and investment processes in professional service groups this article describes and analyses the size and character of investments the investment criteria and the investment processes in some professional service groups the focus is on means of control used by the corporate level to influence the volume and direction of investments in groups of companies comparisons are made with standardized service and manufacturing groups professional service groups are of special interest because theirs is a growth industry moreover many manufacturing groups have become more knowledge intensive and have adopted project based structures similar to those found in professional service groups the article shows that professional service groups invest just as heavily as do manufacturing firms but concentrate their investments on training and the development of new knowledge the principles of investment planning and control are the same as in manufacturing groups but the means and the weight attached to them differ investment requests are initiated on the business unit level and major investment requests are channelled through the executive team system for approval however there is no system of defining requesting and reviewing intangible investments rather review is by projects and units the focus is on market and social not administrative means of control

food and agriculture shifting landscapes for policy this paper describes the ways in which changing consumption patterns and production technologies have altered the boundaries between agriculture and food increasing income and urbanization have driven a steady increase in the demand for prepared and processed foods reducing the need for in home preparation but this well documented transition has in turn led to a shift in the structure of the food industry with manufacturers and processors playing an ever larger role relative to farmers most prominently in the us and european countries but also in the developing world the shift is evident in employment patterns and trade patterns as well as in production and value addition we argue that regulatory systems and policies still tend to equate food with farming reflecting the realities of the last century more than the policy challenges of today

some dynamic aspects of food standards food standards have existed since the beginning of trade and exchange but have increased and expanded in recent years affecting global and local value chains this has triggered vigorous debates on the impacts on trade and development standards may simultaneously enhance economic efficiency and redistribute rents complicating policy analysis and implying that the economics and the politics of standards are often hard to separate while substantial research has contributed important insights dynamic aspects of standards have not received much attention i present a framework to illustrate some dynamic economic and political aspects of standards in closed and open economies this framework integrates changes over time in preferences implementation costs and protectionist pressures as determinants of standards and suggests explanations for persistent differences in food standards across countries hysteresis in standards can persist due to protectionist motives even if the initial standards were not introduced for protectionist reasons i use some historical cases to document both the persistence and adjustment of standards over time and with international integration

food value chain transformations in developing countries selected hypotheses on nutritional implications we examine how the transformation of food value chains fvcs influence the triple malnutrition burden undernourishment micronutrient deficiencies and over nutrition in developing countries we propose a fvc typology modern traditional modern to traditional and traditional to modern that takes into account the participants the target market and the products offered next we propose selected hypotheses on the relationship between each fvc category and elements of the triple malnutrition burden the primary finding is that the transformation of fvcs creates challenges and opportunities for nutrition in developing countries for example modern fvcs may increase over nutrition problems and alleviate micronutrient deficiencies for urban people with relatively high incomes however they have little nutritional impacts among rural residents and urban poor people who primarily depend on traditional fvcs to access adequate quantities of calories and micronutrients in addition modern food manufacturers are leveraging traditional distribution networks modern to traditional fvcs substantially increasing access to low priced processed packaged foods in rural areas and low income urban neighbors with mixed impacts on the triple burden of malnutrition further research should focus on the influence of fvc transformation on reduction of micronutrient deficiencies on modeling demand substitution effects across food categories and the attendant policy implications for malnutrition

advertising expenditure and consumer prices this paper studies the effect of a change in the marginal costs of advertising on advertising expenditures of firms and on consumer prices i make use of a policy change in austria that involved an increase of the taxation of advertising in parts of the country and a simultaneous decrease in other parts i show that advertising expenditures of firms move quickly in the opposite direction of the marginal costs of advertising consumer prices increase with advertising in some industries and decrease in others this effect correlates with informational differences in advertisements across industries

impacts of supermarkets on farm household nutrition in kenya summary many developing countries experience a food system transformation with a rapid growth of supermarkets we analyze impacts of supermarkets on farm household nutrition with survey data from kenya participation in supermarket channels is associated with significantly higher calorie vitamin a iron and zinc consumption we use simultaneous equation models to analyze impact pathways supermarket supplying households have higher incomes a higher share of land under vegetables and a higher likelihood of male control of revenues furthermore income and the share of land under vegetables have positive impacts while male control of revenues has negative impacts on dietary quality policy and further research implications are discussed

strategic entry deterrence in analyzing deterrence of large scale entry two classes of entry barriers may be distinguished an innocent entry barrier is unintentionally erected as a side effect of innocent profit maximization in contrast a strategic entry barrier is purposely erected to reduce the possibility of entry two types of innocent barriers may also be distinguished a postentry absolute advantage has the property that if entry did occur the established firm would be at a profit advantage over the entrant examples are superior technology or product design patents and lower input prices a preentry asymmetry advantage arises from the fundamental preentry asymmetry between established firm and potential entrant before the entrant makes his entry decision the established firm has already committed resources this prior existence gives first move advantages the preentry asymmetry is independent of symmetry or asymmetry in the rules the equilibrium concept of the postentry game that might ensue even if the postentry game will be played according to nash cournot or entrant as leader rules the preentry leadership

governance and trade in fresh vegetables the impact of uk supermarkets on the african horticulture industry production of fresh vegetables for export has grown rapidly in a number of countries in sub saharan africa over the last decade this trade brings producers and exporters based in africa together with importers and retailers in europe large retailers in europe play a decisive role in structuring the production and processing of fresh vegetables exported from africa the requirements they specify for cost quality delivery product variety innovation food safety and quality systems help top determine what types of producers and processors are able to gain access to the fresh vegetables chain and the activities they must carry out the control over the fresh vegetables trade exercised by uk supermarkets has clear consequences for inclusion and exclusion of producers and exporters of differing types and for the long term prospects for the fresh vegetables industry in the two major exporting countries studied kenya and zimbabwe

output and welfare effects of optimal price discrimination in markets segmented at the initiative of the seller abstract this paper investigates the output and welfare effects of optimal price discrimination in markets segmented at the initiative of the seller a market with n segments and prices is compared to a noncooperative cournot nash oligopoly with n competitors output and welfare are greater than less than equal to cournot nash levels when the demand function is concave convex linear from below

food safety and urban food markets in vietnam the need for flexible and customized retail modernization policies access to safe and healthy food is a crucial element of food security in vietnam the safety of daily vegetables is of great concern to both consumers and policymakers to mitigate food safety risks the vietnamese government enforces rules and regulations and relies strongly on a single approach for organizing food provision being modernizing retail by replacing wet markets with supermarkets in general reorganizing food provision in this way is increasingly considered to be a guarantee for food safety especially in urban settings with growing populations to assess the effectiveness of this induced retail modernization of the fresh vegetables market in vietnam s capital hanoi this paper examines for whom and under which conditions does this approach deliver the desired outcomes the survey data and interviews show that ongoing retail modernization in hanoi reaches only a minor segment of the population and drives a large group of shoppers into informal vending structures on the basis of five case studies this paper demonstrates how similar supermarket interventions can yield contrasting outcomes when they do not accommodate for differences in shopper population and do not adapt to variations in the urban conditions to reduce exposure to unsafe food particularly for poorer segments of the population we conclude that developing a flexible portfolio of retail modernization pathways and adopting a reflexive policy approach provide better impact and leverage as opposed to the current trend of promoting supermarkets as a single ideal type form of food shopping

the role of obsolescence and inventory costs in providing commitment this paper modifies the cournot and stackelberg models to allow the firms to sell less than they have produced and to store the unsold portion of their output as inventory even if one of the firms can choose its output before the other if it is costless to carry unsold goods forward then the cournot outcome emerges we show however that costs of carrying the inventory forward endow the firms with a limited degree of commitment to sell what they have produced this partially restores the first mover advantage if the firms choose their outputs simultaneously the cournot outcome emerges and has locally consistent conjectures

small farmers ngos and a walmart world welfare effects of supermarkets operating in nicaragua despite more than a decade of ngo and government activities promoting developing world farmer participation in high value agricultural markets evidence regarding the household welfare effects of such initiatives is limited this paper analyzes the geographic placement of supermarket supply chains in nicaragua between 2000 and 2008 and uses a difference in difference specification on measures of supplier and non supplier assets to estimate the welfare effects of small farmer participation though results indicate that selling to supermarkets increases household productive asset holdings they also suggest that only farmers with advantageous endowments of geography and water are likely to participate

trade standards and poverty evidence from senegal summary in the debate on trade and poverty it is argued that standards act as trade barriers and cause marginalization of the poor this paper quantifies income and poverty effects of high standards trade and integrates labor market effects by using company and household survey data from the vegetable export chain in senegal we find that exports grew sharply despite increasing standards contributing importantly to rural incomes and poverty reduction tightening standards induced a shift from smallholder contract farming to integrated estate production altering the mechanism through which poor households benefit through labor markets instead of product markets

capital budgeting methods among sweden s largest groups of companies the state of the art and a comparison with earlier studies abstract this study presents a general description of the state of the art of capital budgeting methods used by swedish corporations it is based on a questionnaire sent to 528 companies selected from 500 of the largest swedish corporations and some from the o list of companies the response rate is 24 4 the study shows that the public sector companies are most frequent users of discounted cash flow dcf methods the payback method is the most used in all industries also matters size of company the use of the net present value method has increased over the years although the use of dcf methods is generally unchanged value based management models have been introduced in the listed companies another conclusion is that tradition is an important factor explaining the choice of capital budgeting method large companies within the manufacturing industry use dcf methods more often than other companies in general the companies seem unconcerned with the tax consequences of capital budgeting decisions it would appear as if the public companies have not adopted capital budgeting practices supporting shareholder value increases

new venture strategy and profitability a venture capitalist s assessment abstract this study uses theoretically justified criteria from the industrial organization io strategy literature and applies it to a new domain namely venture capitalists decision making specifically the study investigates the types of information venture capitalists utilize when evaluating new ventures and how venture capitalists use this information to assess likely new venture profitability in the interest of advancing our understanding of the decision making policies of venture capitalists this study addresses many of the limitations of previous research a review of io research suggests important relationships between a number of strategy variables and new venture profitability some of the relationships proposed by io strategy research are contingent in nature the strategy variables and their relationships with profitability are investigated in the domain of venture capitalists decision making individual and aggregate decision making analyses identified those strategy variables criteria venture capitalists utilize in assessing likely new venture profitability namely timing key success factor stability lead time competitive rivalry educational capability industry related competence timing key success factor stability interaction timing lead time interaction and timing educational capability interaction on average the most important criterion for venture capitalists in their assessment of profitability is industry related competence the second tier of importance is competitive rivalry timing and educational capability the third tier of importance is lead time key success factor stability and timing lead time interaction other interactions are less important therefore while venture capitalists use contingent decision policies main effects dominate if venture capitalists use a reported 8 to 12 minutes on average to evaluate a business plan sandberg 1986 then this study s findings may help the inexperienced venture capitalist allocate time towards assessing those attributes of primary importance although more complex relationships exist between the attributes the inexperienced venture capitalist can take comfort from this study s findings that main effects dominant amongst senior venture capitalists senior venture capitalists may take less comfort from their importance placed on main effects in light of research from io which suggests the importance of contingent relationships the results may also have practical application towards training how should venture capital firms train their new employees should venture capital firms rely solely on experienced venture capitalists lecturing the inexperienced on the criteria they use in assessing a new venture proposal like most decision makers venture capitalists have limited insight into their assessments and venture capital firms need to be aware of the gap between espoused policies and policies in use the information being taught needs to be supplemented with venture capitalists decision making research that investigates decision policies in use such as this study venture capitalist training could also involve experiential learning in conjunction with cognitive feedback about the decision policies used to accelerate the learning process experiential learning using cognitive feedback maximizes industry related learning while minimizing the cost of inexperienced decisions for the entrepreneur seeking capital this increased understanding of venture capitalists decision making may help them better target their business plans and presentations at those criteria venture capitalists find most critical to the profitability of a new venture

westernization of asian diets and the transformation of food systems implications for research and policy abstract rapid economic and income growth urbanization and globalization are leading to a dramatic shift of asian diets away from staples and increasingly towards livestock and dairy products vegetables and fruit and fats and oils while the diversification of diets away from the traditional dominance of rice with rising incomes is expected and observed current food consumption patterns are showing signs of convergence towards a western diet the diet transition is characterized by increased consumption of wheat temperate fruit and vegetables and high protein and energy dense food globalization and the consequent global interconnectedness of the urban middle class is the driving force behind the convergence of diets the rapid spread of global supermarket chains and fast food restaurants is reinforcing the above trends the growing demand for diet diversity cannot be met solely by the traditional food supply chain it requires the modernisation of the food retail sector and the vertical integration of the food supply chain in effect linking the consumers plate to the farmers plow as a consequence asian agriculture is on an irreversible path leading away from its traditional pre occupation with cereal crop production especially rice towards a production system that is becoming increasingly commercialized and diversified this paper describes the determinants and trends in the diversification and westernization of asian diets implications of the evolving demand trends for food supply and retail systems are presented the paper discusses the prospects for small farmer participation in the emerging food supply system with a particular emphasis on asian rice production systems finally the paper considers emerging challenges for food policy small holder welfare and agricultural research and development priorities

strategic entry deterrence recent developments in the economics of industry this paper reviews the recent developments in the economics of industry with respect to strategic entry deterrence starting from bain s 1956 classical analysis a simple two stage game between an incumbent firm and a potential entrant is used to present the general structure of the entry deterrence problem commitments credible threat and sub game perfection are illustrated in this context the various strategic variables that an incumbent firm can use to bar entry are discussed the issue of whether a group of incumbents can noncooperatively deter entry is taken up and some empirical evidence is reviewed copyright 1989 by blackwell publishers ltd

strategic deterrence of sequential entry into an industry industrial entry deterrence is typically studied in a setting where an established firm or firms confront and attempt to deter a single potential competitor during the evolution of most industries however a sequence of firms enters or attempts to enter at distinct points in time consideration of issues arising from sequential entry fundamentally alters the qualitative nature of the deterrence decision undertaken by incumbent firms within a sequential setting counterintuitive behavior may be observed specifically numerous government policies designed to decrease industrial concentration penalties for anticompetitive practices subsidization of entry consent decrees restructuring industries may have the opposite effect

economic impact of direct marketing and contracts the case of safe vegetable chains in northern vietnam abstract the paper investigates the respective impacts on incomes of contractual arrangements direct sales and spot marketing for safe vegetable farmers in northern vietnam it is based on a survey of 137 peri urban vegetable farmers that was analyzed using different econometric methods to correct selection biases direct sales and contractual arrangements have a significant positive impact on income compared to spot marketing contracts have less impact on income compared to direct sales it is recommended that policies be formulated to stimulate direct dealings between farmers and consumers which enhance consumer confidence in terms of quality and translate into higher farmer income than anonymous exchanges or contracts

post green revolution food systems and the triple burden of malnutrition developing country food systems have changed dramatically since the green revolution period at the same time malnutrition still represents a challenge and is now understood to encompass the three simultaneous dimensions of undernourishment micronutrient deficiencies and over nutrition manifest in overweight and obesity these changes in food systems and in the understanding of the global malnutrition challenge necessitate fresh thinking about food systems based strategies to reduce malnutrition this paper introduces a special section that offers such new perspectives we discuss trends with respect to indicators of the triple burden of malnutrition to understand the extent of global malnutrition challenges and then relate those to food systems transformation in developing countries

supermarkets and food consumption patterns the case of small towns in kenya abstract this paper investigates the effect of supermarkets on food consumption patterns in urban kenya using cross sectional household survey data collected in 2012 to establish causality we selected study sites that differ in their supermarket access and employ instrumental variable techniques to allow for endogeneity of supermarket purchases we find that supermarket purchases increase the consumption of processed foods at the expense of unprocessed foods supermarket purchases increase per capita calorie availability which is linked to lower prices paid per calorie particularly for processed foods our results imply that supermarkets contribute to dietary changes commonly associated with the nutrition transition the effects on nutrient adequacy are less clear

excess capacity and limit pricing an empirical test entry may be inhibited by expectations that incumbents have lower marginal costs incumbents may be able to use limit pricing or excess capacity to further this expectation we construct an empirical model of oligopoly capacity and pricing decisions and of entrant responses the results support the hypothesis that both lower prices and greater excess capacity inhibit entry they further support limit pricing but provide no evidence that oligopolies deliberately install excess capacity to deter entry the results suggest however that limit pricing firms may exploit the entry inhibiting effects of unintended excess capacity by raising their limit prices

prices prices and prices a study in the airline sector abstract this article creates and empirically analyzes a dynamic pricing framework the model includes the main theories on prices in the literature and dynamically analyzes how companies change their pricing policies according to different circumstances through the use of regressions the article shows the relative long and short term impact on pricing equations strategic versus operational matters and on production conditions versus demand perspectives in the setting of operational prices in addition it highlights how the proportions of these pricing perspectives change in the airline sector according to the effect of the environment on the configuration of the strategy determined by monthly and hourly seasonality and also according to the nature of this competitive strategy determined by the characteristics of the company and the destination airport the results confirm our framework and show how firms combine the different perspectives in their pricing strategies

sustainability standards gender and nutrition among smallholder farmers in uganda abstractsustainability standards are gaining in importance in global markets for high value foods while previous research has shown that participating farmers in developing countries may benefit through income gains nutrition impacts have hardly been analysed we use survey data from smallholder coffee farmers in uganda certified under fairtrade organic and utz to analyse impacts on food security and dietary quality estimates of instrumental variable models and simultaneous equation systems show that certification increases calorie and micronutrient consumption mainly through higher incomes and improved gender equity in certified households women have greater control of coffee production and monetary revenues from sales

farmers welfare and changing food prices nonparametric evidence from rice in madagascar this paper uses nonparametric density estimation and kernel smoothing techniques to examine the instantaneous distributional implications of rice price changes in madagascar while many farmers do not participate in product markets as either buyers or sellers and net sales or marketable surplus are fairly small for many others the roughly one third of rice farmers who fall below the poverty line face significant negative first order welfare effects from increases in the mean or variance of rice prices conversely the first order gains from rice price increases are highly concentrated among the largest rice farmers and particular regions in madagascar

some urban facts of life implications for research and policy abstract this review of recent literature explores the challenges to urban food and nutrition security in the rapidly urbanizing developing world the premise of the manuscript is that the causes of malnutrition and food insecurity in urban and rural areas are different due primarily to a number of phenomena that are unique to or exacerbated by urban living these areas include a a greater dependence on cash income b weaker informal safety nets c greater labor force participation of women and its consequences for child care d lifestyle changes particularly diet and exercise patterns e greater availability of public services but questionable access by the poor f greater exposure to environmental contamination and g governance by a new possibly nonexistent set of property rights the main focus is on identifying what is different about urban areas so as to better frame the program and policy responses

supply chain differentiation contract agriculture and farmers marketing preferences the case of sweet pepper in thailand there is an emerging body of literature analyzing how smallholder farmers in developing countries can be linked to modern supply chains however most of the available studies concentrate on farm and farmer characteristics failing to capture details of institutional arrangements between farmers and traders moreover farmers preferences have rarely been considered here we address these gaps by analyzing different market channels for sweet pepper in thailand using data from a survey and choice experiment with farmers we find that there is a general preference for marketing options that do not involve a contract additional provision of inputs and credit can increase the attractiveness of contracts yet the most important factor for farmers is to personally know the buyer they deal with which may be related to issues of trust some policy implications are discussed

how much priority is given to nutrition and health in the eu common agricultural policy agriculture in the european union eu is strongly influenced by the common agricultural policy cap there have been repeated calls for cap to address nutrition related health particularly obesity and non communicable disease ncd in the eu however aligning agricultural policy such as cap with nutrition is complex not least because the aims of agricultural policy are predominantly economic presenting a challenge for developing coherence between agricultural trade and health policy this research examined the political priority given to nutrition related health concerns within cap to date and the solutions suggested by agricultural trade and health policy makers and public health nutrition advocates via interviews of 20 high level participants from respective sectors the participants provided diverse perspectives often varying by sector and institution on the connections between agricultural policy and nutrition related health the extent to which nutrition concerns have been addressed via cap and whether cap is an appropriate and effective policy approach to improve nutrition related health in the eu in the future the key findings suggest the need for communication and agreement of clear high level nutrition guidelines clarity on the eu mandate to address nutrition related health concerns via policy and stronger engagement of civil society in the issues if cap is to address nutrition more than it is doing currently the difference in worldviews between agricultural trade representatives and those from public health also needs to be addressed

industry differences in the persistence of firm specific returns some firms such as kellogg nestle hewlett packard and boeing have consistently earned significantly higher returns than their immediate competitors why do intraindustry rents persist for these firms competition typically erodes these rents as evidenced by the strong convergence of firm profitability to the industry mean illustrated in figure 1 i claim that the persistence of these firmspecific rents depends at least partly on industry economic structure similar to richard e caves and michael e porter s 1977 mobility barriers so the rents are more persistent in some industries than others in this paper i test which of the theoretical industry factors are significant to support my claim i also show that the persistence of abnormal returns differs widely and systematically across industries for example an industry with highly persistent profitability differences is the american automobile industry in the 1970 s as illustrated by figure 2 which graphs differences in returns on assets roa s over time throughout the 1970 s general motors maintained a persistent significant profitability advantage over ford while ford held a persistent advantage over chrysler this situation did change later but it is still true that during the 1970 s there was no apparent convergence of profitability differences among the big three auto makers a comparison of figures 1 and 2 suggests that the economy wide result of figure 1 is merely an average over very different industries with convergence rates ranging from almost zero as in automobiles in the 1970 s to very rapid my methods for estimating persistence of above average returns improve on previous studies in several ways first i only consider the persistence of returns around the industry mean the persistence of this intra industry or firm specific rent rather than total rent has not been previously investigated yet the factors affecting firm specific rents need not be the same as those affecting industry rents second i estimate persistence in several ways finally i use a wider range of explanatory variables than earlier studies this study is structured as follows section i explains the concept of persistent firmspecific rents later sections specify the empirical model and estimate persistence by industry section ii theoretically relate industry factors to these varying persistence estimates section iii discuss cross sectional regression estimates section iv and provide conclusions section v

trade and dietary diversity in eastern europe and central asia abstract in public and academic debates the linkages between agricultural markets and nutrition across the world are vividly discussed this paper contributes to the ongoing debate by analyzing the relationship between greater openness to trade and dietary diversity it focuses on the post communist countries of eastern europe and central asia where trade reforms triggered growth in trade flows and foreign direct investment which in turn affected food systems in these countries this shift provides a natural experiment for studying the effects of trade openness on agricultural markets and consumer behaviour reduction in trade barriers for instance in the context of the accession to the wto and the eu and the gradual integration with world markets after 1991 had implications for diets through changes in production prices and incomes we utilize country level panel data for 26 post communist countries in the period 1996 2013 to assess the effects of trade costs agricultural trade openness and incomes on dietary diversity measured by the shannon entropy index the results from fixed effects and instrumental variables estimation are consistent with previous findings that income growth affects dietary diversity positively they also provide novel evidence that trade barriers reduce variety of products available in domestic markets in particular fruits and vegetables

defensive marketing strategies an equilibrium analysis based on decoupled response function models the entry of a new product attacker into a competitive market is likely to provoke responses from some or all of the existing products defenders this paper investigates the development of optimal defensive strategies based on an understanding of the possible reactions of all the defenders to an optimal attack following lane lane w j 1980 product differentiation in a market with endogenous sequential entry bell j econom 11 1 spring 237 260 we assume that n products each enter sequentially with perfect foresight on subsequent entry then based on new technology an unanticipated attacker enters the n defenders respond in price but not position according to lane s model once this equilibrium is obtained advertising and distribution response functions scale sales we show that under these decoupled response function models of advertising and distribution uniformly distributed tastes and nonincreasing market size the optimal defense for all existing brands is to decrease their respecti

what is a barrier to entry the present article is an attempt to resolve the controversies concerning the concept of barriers to entry we begin by contrasting the definitions of an entry barrier proposed in the economics literature we then introduce a classification system to clear up the existing confusion and we employ it to assess the nature of the barriers posed by scale economies and sunk costs

following up on smallholder farmers and supermarkets in kenya in many developing countries supermarkets are expanding rapidly this affects farmers marketing options previous studies have analyzed welfare effects of smallholder participation in supermarket channels from a static perspective using cross section data we develop a conceptual framework and use panel data to better understand participation and impact dynamics the analysis focuses on vegetable producers in kenya participation in supermarket channels is associated with income gains however many farmers have dropped out of the supermarket channel due to various constraints the initial income gains cannot be sustained when returning to the traditional market organizational support may be needed to avoid widening income disparities

assessing food value chain pathways linkages and impacts for better nutrition of vulnerable groups abstract this article offers insights into assessing the effectiveness of post farm gate agri food value chains at improving the nutrition intake of vulnerable groups it develops a conceptual framework integrating the value chain concepts with agriculture and nutrition and identifies key outcomes and requirements for value chains to be successful at delivering substantive and sustained consumption of nutrient dense foods by poor households other frameworks linking value chains with nutrition have been published but this article provides the analytical lens to assess post farm gate value chains to achieve improvements in the intake of nutritious foods by the target populations food must be safe to eat on a sustained basis nutrient dense at the point of consumption and consumed in adequate amounts on a sustained basis this shifts the focus to the role of public actions and policy in terms of shaping the functioning of food value chains by assessing the limits of what business can and cannot contribute in a given market context policy makers and other relevant stakeholders will be more capable of creating an appropriate institutional environment that shapes how value chains operate for the benefit of vulnerable target groups designing and implementing effective policies and strategies with respect to the role and use of market based interventions

implications of higher global food prices for poverty in low income countries in many poor countries the recent increases in prices of staple foods raise the real incomes of those selling food many of whom are relatively poor while hurting net food consumers many of whom are also relatively poor the impacts on poverty will certainly be very diverse but the average impact on poverty depends upon the balance between these two effects and can only be determined by looking at real world data results using household data for ten observations on nine low income countries show that the short run impacts of higher staple food prices on poverty differ considerably by commodity and by country but that poverty increases are much more frequent and larger than poverty reductions the recent large increases in food prices appear likely to raise overall poverty in low income countries substantially

simultaneous equations models of the structure performance paradigm abstract this paper is concerned with determining the dimension of the simultaneous equations model surrounding the basic profits concentration relationship a very general model is considered and then simplified using a simple test for exogeneity and it is concluded that the model is nonlinear in concentration and that simultaneous interaction occurs between profits and foreign competition variables
