strategic and regulatory approaches to increasing women in leadership multilevel targets and mandatory quotas as levers for cultural change while substantial evidence is emerging inter nationally of positive increases in the participation of women on company boards there is less evidence of any significant change in the proportion of women in senior executive ranks this paper describes evidence of positive changes in the number of women on boards in australia unfortunately these changes are not mirrored in the senior executive ranks where the proportion of women remains consistently low we explore some of the reasons for these disproportionate changes and examine the likely effect of the recent amendments to the australian stock exchange s corporate governance code designed to improve gender diversity both on boards and throughout organisations based on the early corporate response to these regulatory changes it is interesting to consider whether australia s approach in promoting voluntary self regulation at the corporate level may be as effective in the long run as the emerging trend in europe to apply legislated quotas for female corporate board representation interview evidence is presented suggesting that the primary reasons for the lack of women in leadership are not simply lack of opportunity at the apex of the corporation but issues at mid management level that are unlikely to be resolved by mandatory board quotas in some circumstances carefully monitored voluntary targets may be more effective at promoting cultural and strategic change at the heart of the corporation in summary mandatory quotas set through hard law usually with sanctions for noncompliance may achieve early and significant results in terms of female board representation however voluntary targets for women s participation on boards and in executive ranks proposed in soft regulation such as corporate governance codes and set as part of corporate strategy may promote more effective cultural and practical change in support of greater representation of women in leadership

women leaders and social performance evidence from financial cooperatives in senegal how do women leaders such as board members and top managers influence the social performance of organizations this paper addresses the question by exploiting a unique database from a senegalese network of 36 financial cooperatives we scrutinize the loan granting decisions made jointly by the locally elected board and the top manager assigned by the central union of the network our findings are threefold first female dominated boards favor social orientation second female managers tend to align their strategy with local boards preferences third the central union tends to assign male managers to female dominated boards probably to curb the boards social orientation

women as policy makers evidence from a randomized policy experiment in india this paper uses political reservations for women in india to study the impact of women s leadership on policy decisions since the mid 1990 s one third of village council head positions in india have been randomly reserved for a woman in these councils only women could be elected to the position of head village councils are responsible for the provision of many local public goods in rural areas using a dataset we collected on 265 village councils in west bengal and rajasthan we compare the type of public goods provided in reserved and unreserved village councils we show that the reservation of a council seat affects the types of public goods provided specifically leaders invest more in infrastructure that is directly relevant to the needs of their own genders

alleviating transitory food crises in sub saharan africa international altruism and trade the donor community has responded to unexpected or transitory drops in domestic food production in many countries in sub sabaran africa an empirical framework estimates and analyzes the correlation between this food aid and domestic production both emergency food aid and commercial imports are used to offset the effects of negative output shocks in sub saharan african countries the major recipients of global emergency food aid on average every one ton drop in cereal production is offset by the delivery of 0 8 tons of cereal and dairy products from abroad over four years most food aid arrives within a year of a shock and correlation of shocks over time along with the differences between crop years and calendar years may explain the link between aid and production the economic and political considerations also determine the global response to the emergency food needs of countries in africa the international response is not contingent on the form of government or the level of political and human rights violations poorer countries and those with well established nonemergency food aid programs receive larger amounts of emergency aid when needed food aid has long helped low income countries to sustain domestic food supplies and cope with transitory food insecurity and it has also been used to accelerate agricultural development and increase food production but food aid has been heavily criticized in the past decade on several grounds first it has been charged that the international response to food crises is slow meager and inefficient a related accusation suggests that countries granting emergency food aid disciriminate on the basis of the political and economic orientation of the recipient country second food aid has been thought to discourage domestic food production thus leading to long term dependence on donors finally it has

vive la difference social banks and reciprocity in the credit market social banks are financial intermediaries paying attention to non economic i e social ethical and environmental criteria to investigate the behavior of social banks on the credit market this paper proposes both theory and empirics our theoretical model rationalizes the idea that reciprocity can generate better repayment performances based on a unique hand collected dataset released by a french social bank our empirical results are twofold first we show that the bank charges below market interest rates for social projects second regardless of their creditworthiness motivated borrowers respond to advantageous credit terms by significantly lowering their probability of default we interpret this outcome as the first evidence of reciprocity in the credit market

cereals demand in the sahel and potential impacts of regional cereals protection abstract recent policy debate in the sahel has focused on a regional protection zone for cereals this paper discusses crosscountry evidence of consumption patterns and the sensitivity of these to policy variables and considers potential income distribution and efficiency impacts of a rice tariff increase a tariff would hurt the poor in the short term because the poor depend to a large extent on rice as a fast food purchased from street vendors the trend toward rice consumption is a long term structural phenomenon linked to urbanization rather than to short term price changes maize and millet sorghum are substitutes in consumption which should serve to encourage development of maize in the guinean zone to help assure sahel food security in drought years

income elasticities for food calories and nutrients across africa a meta analysis abstract this paper aims to provide a better understanding of the relationship between income and the demand for different types of food nutrients and calories in africa by conducting a meta analysis of income elasticity estimates we build a meta sample consisting of 1523 food income elasticities 369 nutrient income elasticities and 123 calorie income elasticities extracted from 66 primary studies covering 48 african countries the sample displays a large heterogeneity in income elasticity estimates which our meta analysis aims to explain by looking into attributes of the primary studies and characteristics of the countries considered there are significant differences in the size of the income elasticities across food and nutrient groups foods that make up basic diets tend to have lower income elasticities while elasticities are considerably higher for less basic and more aspirational foods the role of methodological attributes of the primary studies in explaining heterogeneity is found to be small overall our results confirm that although income growth in africa will increase food consumption and lead to more nutritionally diverse diets it is also associated with excessive intakes of fats and sugars raising concerns about over in addition to undernutrition this suggests that income based policies can still play a role in the fight against hunger but that targeted programs are needed to promote nutritionally valuable and healthy diets

food security and hedonic behaviour a case study of sao tome e principe abstract food security is still one of the main concerns in economic policy making in less developed countries the objective of the present study is to analyse technological innovation and technological change induced by economics forces with special attention to consumer behaviour consumer choice is studied together with the technological change process from the consumption side such that efficiency problems can be handled if a certain number of weak assumptions can be accepted the framework of the lancaster model is used to study the impact on food security on sao tome e principe changing from a centralised economic policy to a market oriented economy the paper addresses the need to understand how consumption innovation with the introduction of locally produced food consumption can be an efficient solution from the consumption point of view the results obtained with the introduction of matabala into the consumption choice set show that free market functioning supports local products consumption as an efficient solution in sao tome e principe

the empirics of microfinance what do we know microfinance has received a lot of attention recently both from policy makers as well as in academic circles two of the main topics that have been hotly debated are explaining joint liability group lending and its implications for reducing information asymmetries and the trade off between the financial sustainability and outreach of microfinance programmes this feature contains three novel empirical contributions providing new insights with respect to why and how joint liability group lending works it also contains the first large scale systematic analysis of the trade off between financial performance and outreach of microfinance institutions

household food demand in burkina faso implications for food policy abstract chronic food production deficits since the early 1970s have prompted policymakers of burkina faso to emphasize technological research with the goal of increasing the production of the most consumed locally grown cereals sorghum millet and maize meanwhile urban consumers have been developing preferences for rice and wheat cereals that are primarily imported this study estimates demand relationships among food items in ouagadougou burkina the results of the estimation suggest that prices income household composition education marital status and urbanization were jointly important in explaining household expenditure allocations both local and imported cereal consumption responded positively to an income increase however incremental income changes would lead to relatively greater consumption of locally produced cereals by low income households whereas high income households would consume relatively more wheat and rice the household model is then used to demonstrate its relevance in addressing food policy issues by forecasting the levels of urban grain demand under alternative income and demographic scenarios with increased production due to advances in technology the urban demand levels do not exhaust the rural surplus of local cereals but deficits persist in the rice wheat sector the results underscore the importance of technological research since burkina could become self sufficient in at least the production of sorghum millet and maize

microfinance and poverty a macro perspective we test the hypothesis that microfinance reduces poverty at the macro level using cross country and panel data which are constructed by the microfinance information exchange data on microfinance institutions mfis and the world bank data taking account of the endogeneity associated with mfis loans we show that a country with higher mfis gross loan portfolio per capita tends to have lower levels of poverty indices contrary to recent micro evidence our results suggest that microfinance significantly reduces poverty at macro level and thus reinforce the case for channeling funds from development finance institutions and governments of developing countries into mfis

are estimates of calorie income fxelasticities too high a recalibration of the plausible range abstract the wide range of calorie income elasticities in the literature results in large part from the particular calorie and income variables used for estimation elasticities across four estimation techniques and four calorie income variable pairs for a sample of philippine farm households ranged from 0 03 to 0 59 estimates associated with calorie availability are biased upwards first because random errors in measuring food purchases are transmitted by construction both to calorie availability and total expenditures and second because the residual difference between family calorie intake and household calorie availability will often increase with income the calorie intake total expenditure variable pair gives the preferred elasticity estimate in the 0 08 0 14 range

a cross section analysis of household demand for food and nutrients in tanzania abstract undernutrition and malnutrition are still problems of unacceptable proportions in many developing countries however the debate on the roles of income and other socio economic variables such as women s education and household size on food and nutrient demand continues this study examines the demand for food and nutrients amongst households in tanzania using recent survey data a quadratic almost ideal demand system quaids is employed to estimate price and expenditure elasticities as well as the impact of socio economic variables on food demand patterns a moment based instrumental variable approach is then used to analyse the determinants of nutrient demand the results show that income and other socio economic variables exert significant effects on the demand for food and nutrients the estimated expenditure elasticities for the nutrients range from 0 307 for iron to 1 26 for vitamin b12 the elasticities are higher for those micronutrients that are consumed through animal products and lower for those micronutrients that are mainly obtained through staple foods these results reflect the higher expenditure elasticities for meat fish eggs milk and milk products as well as fruits and vegetables relative to cereals and pulses reinforcing the assertion that the demand for vitamins a and b12 as well as calcium and zinc will increase with rising income

gender and microfinance performance why does the institutional context matter summary this paper investigates why and under which institutional circumstances female membership in microfinance institutions mfi improves mfi performance in terms of debt repayment specifically this paper theorizes that female membership in mfis improves the mfi s performance through enhanced debt repayment especially under adverse cognitive and regulatory institutional conditions we draw upon unique qualitative and quantitative data covering 26 microfinance projects in 22 african eastern european latin american and asian countries this study has implications for the microfinance literature in that it challenges the widely held assumption that female participation has a positive effect on mfi performance under all institutional circumstances

women empowerment and economic development women empowerment and economic development are closely related in one direction development alone can play a major role in driving down inequality between men and women in the other direction empowering women may benefit development does this imply that pushing just one of these two levers would set a virtuous circle in motion this paper reviews the literature on both sides of the empowerment development nexus and argues that the interrelationships are probably too weak to be self sustaining and that continuous policy commitment to equality for its own sake may be needed to bring about equality between men and women

credit constraints credit unions and small scale producers in guatemala abstract efficient and equitable development outcomes may depend in part on whether formal financial institutions leave low wealth producers tightly constrained in their access to credit if so can cooperative institutions efficiently relax these constraints these issues are explored using survey data gathered from 950 small scale producer households in areas of guatemala with market oriented credit unions that mobilize savings and make unsubsidized loans nonprice rationing by banks is found to be common among lower wealth households while credit unions relax credit constraints for a significant portion of those rationed by banks but not the poorest of the study households

unsubsidized microfinance institutions this paper starts from the observation that 23 of the world s microfinance institutions mfis manage without subsidies we examine how unsubsidized institutions cope with their social mission overall the lack of subsidies worsens social performances however our results show that strategies to achieve financial self sufficiency differ substantially across regions african and asian mfis compensate for non subsidization by charging higher interest rates in eastern europe and central asia unsubsidized mfis find it more suitable to target less poor clients unsubsidized latin american mfis tend to reduce their share of female borrowers

rural works programs in india costs and benefits abstract a sequential applied general equilibrium model of the indian economy is used for analyzing the costs and benefits of a rural works program designed to provide employment during slack agricultural seasons through the creation of productive assets such as roads irrigation works schools etc it is shown that such a program if carried out efficiently targeted effectively and financed in a way that does not jeopardize long term growth can be a very effective instrument for alleviating rural poverty in india

changing food patterns in west africa implications for policy research abstract west african consumption of wheat and rice is growing rapidly despite technological barriers to production of these cereals in the region soaring imports are of particular concern in view of likely consumption trends maize imports are also growing rapidly as is production in the more humid countries to the detriment of sorghum the latter is performing relatively better in the drier countries possible factors underlying consumption shifts are discussed including price policies at variance with stated objectives possible policies to slow down these shifts are discussed along with research requirements for effective diagnosis and implementation

food aid a cause of development failure or an instrument for success the role of food aid in furthering the economic development of poor countries and in alleviating the adverse effects on the poor of structural and sectoral adjustment programs is discussed a simple analytical framework for evaluating the incentive and welfare impact of food aid is suggested domestic and international markets for food historically have been subject to severe distortions leading to ever growing food stocks in some mainly rich countries while in others largely poor many cannot afford to consume enough food the possible impact of distortion free global food markets is sketched the use of surplus food for payment of wages in rural work programs has often been proposed as a means to create productive assets while alleviating poverty using an applied general equilibrium model of the indian economy it is shown that a well designed and efficiently implemented food for work program can virtually eliminate abject poverty in india at a modest cost experience with food aid in several other countries is also briefly discussed

practice prize winner eco entega s profitable new customer acquisition on online price comparison sites market liberalization of the german household electricity market has led to an excessive number of competitors 1 150 electricity providers and volatile price dynamics on price comparison sites to date providers that are struggling to achieve a top ranking on price comparison sites do not appear to implement a consistent or elaborate strategy for attracting customers we developed a pricing tool electricity contract optimization eco that addresses this highly competitive market situation by integrating various available data sources such as data from price comparison sites demographic data and regional sales or cost data eco sets regionally varying one time bonuses to attract new customers on price comparison sites with the goal of optimizing sales and profit targets or optimally allocating sales budgets based on two field experiments we demonstrate that eco s optimization procedure reduces entega yearly sales costs for new customer business on average by 35 relative to previously used pri

when and how is the internet likely to decrease price competition conventional wisdom seems to claim that by lowering the cost of distribution and by making search easier for consumer the introduction of the internet is likely to intensify price competition this paper intends to challenge this view by asking when and how is the internet likely to decrease the level of price competition between firms to answer this question we develop an analytic model with the following characteristics on the demand side consumers need to gather information on two types of product attributes digital attributes which can be communicated on the web at very low cost and nondigital attributes for which physical inspection of the product is necessary consumers choose between two brands but are familiar with the nondigital attributes of only the brand purchased on the last purchase occasion on the supply side firms use traditional stores and the internet to inform consumers about their products attributes and to sell their products in this setup we show that the impact of the internet on competition will be radically different depending on the relative importance of parameters describing the relevant shopping and distribution context specifically we find that the introduction of the internet might lead to monopoly pricing when 1 the proportion of internet users is high enough 2 when nondigital attributes are relevant but not overwhelming 3 when consumers have a more favorable prior about the brand they currently own and 4 when the purchase situation can be characterized by destination shopping more surprising we also show that in such cases the use of the internet not only leads to higher prices but can also discourage consumers from engaging in search as such an important message of the paper is that under some conditions the internet might represent an opportunity for firms to leverage their brand loyalty and increase their profits the intuition behind our results is the following the internet allows consumers to evaluate digital attributes easily i e without visiting the stores however nondigital attributes can only be evaluated through physical presence as such for goods where both types of attributes are important the introduction of the net changes the effective cost of search for consumers without the internet the cost of search is the cost of visiting more than one store with the introduction of the net however nonsearching consumers do not have to undertake the shopping trip at all because they can order products on the net thus in the presence of the internet the cost of search is related to the cost of undertaking the entire shopping trip in the case of destination shopping i e when the fixed cost of undertaking the shopping trip is higher than the cost of visiting an additional store the presence of the internet creates higher effective search costs for consumers given this shift of paradigm in search costs due to the internet consumers may not take the risk of searching for products with better nondigital attributes but instead remain with the product they are familiar with this results in increased consumer loyalty which induces firms to increase their prices our results have important managerial implications first they provide guidelines for firms on when i e for which product categories they should consider expanding their distribution network to the internet in this respect an important additional insight of the paper is that the internet can lower price competition and lead to reduced consumer search even if it is more expensive than the traditional distribution channel this can easily be the case if distribution through the internet represents additional costs such as the costs associated with shipping and handling and return policies second the paper also provides guidelines on how to plan the firm s internet strategy interestingly the results suggest that with the general availability of the internet the role of stores might actually become more important while we do not explicitly model a dynamic market our findings together with klemperer s 1987 results suggest that stores might have a key role in consumer acquisition while the internet can help leverage the acquired customer base through demand fulfillment this might imply that for certain product categories firms should actually allocate additional resources to improve their in store environment when considering the internet as a complementary distribution channel

joint determination of food consumption and production in rural sierra leone estimates of a household firm model abstract this paper investigates the determination of food consumption for rural households in sierra leone that produce the foods which they consume a household firm model is estimated with seven commodities including five foods non foods and labor as compared to three commodities in past studies such food disaggregation permits tracing of the effects of socioeconomic variables on household nutrient availability household specialization in production is such that censored data is a problem a tobit approach is used to correct for this for most crops the own price effects on consumption remain negative when a price change is allowed to shift the budget constraint by effecting the profits from home production elasticities of calorie availability with respect to toal expenditure are found to be sizeable varying little by expenditure group the price elasticities of calorie availability are generally positive however an important exception occurs for price of the staple food rice this exception has several important policy implications which are explored

demand for cereal grains in asia the effect of urbanization abstract this paper analyzes the effects of urbanization on demand for cereal grains rice wheat and coarse grains in nine asian countries a complete demand system almost ideal demand system in linear form is estimated in two stages based on aggregate time series data from 1960 to 1988 in the high income countries i e japan and south korea urbanization was observed to significantly reduce demand for cereal grains in the lower income countries demand for cereal grains either increased or remained the same with urbanization among cereal grains urbanization has had negative effects on demand for rice and coarse grains but consistently positive effects on demand for wheat only japan and thailand among the countries studied have negative income elasticities of demand for total cereal grains and for rice in particular hence rice remains a necessity and a normal good in most asian countries previous estimates of income elasticities of rice based on time series aggregate data tend to be lower than those based on cross section household level data when urbanization is explicitly specified in the demand model the estimates of income elasticities from time series data turn out to be consistent with those from cross section data

treating food security and food aid issues at the gatt abstract some food importing gatt members are concerned that multilateral agricultural policy reform as proposed in the uruguay round would endanger their food security particularly if reform results in higher world commodity prices lower government stock levels and weaker incentives for food aid supplies this paper elaborates a set of international policies in support of food security that would be consistent with gatt s main objective of reducing interference by national policies in the free flow of goods this set includes commitments to maintain global food stocks and food aid disciplines for stockbuilding and food aid distribution and support for certain programmes aimed at reducing instability of food production and supply while a guarantee of food security is beyond gatt control and depends ultimately on sustained economic development there are food security enhancing mechanisms that the gatt can support without encouraging new trade distortions

food aid and food markets lessons from mozambique abstract a consensus has emerged on food aid policy acknowledging the importance of short run relief considerations while emphasizing that such policy must be driven by a long run developmental perspective this requires explicit attention to the effects of food aid on food markets yet it has long been clear that short and long run objectives of food aid may conflict this tension stands in high relief in mozambique one of the most food aid dependent countries in the world this paper examines the factors determining the effects of yellow maize food aid on markets for yellow maize and white maize the staple crop in mozambique the paper finds that a food aid has helped fuel the growth of a competitive small scale milling industry and informal marketing system b yellow and white maize are substitutes in consumption and c continued availability of yellow maize food aid at prices well below import parity will depress incentives for producers and traders to invest in the white maize production and marketing system this paper presents recommendations for reforming the monetized food aid program and coordinating it more effectively with emergency aid

adverse incorporation and microfinance among cross border traders in senegal summary this paper highlights the relevance of adverse incorporation as a neglected theoretical approach to debates on microfinance through a case study of cross border traders in senegal although women s organizations do not exclude even the poorest women traders in remote areas were unable to access credit due to particularly harsh standards of joint liability and adverse relations with donors lenders and elite women meanwhile the peer monitoring function of group microcredit schemes is challenged by the fact that traders are strikingly uncritical of defaulting borrowers findings highlight the detrimental consequences of donors misconceptions regarding women s organizations and economic activities

rural women s access to credit market imperfections and intrahousehold dynamics summary credit rationing studies carried out at the household level and based on responses from male heads of households present an incomplete and biased assessment of who is likely to be constrained why they are constrained and what is the extent of the constraints they ignore possibly conflictive intrahousehold dynamics and assume that imperfections in rural financial markets are gender neutral this paper addresses both issues theoretically and empirically the semi cooperative household model developed for this analysis formalizes the conditions under which spouses and particularly women s individual access to credit can be affected by their own position in the financial market as well as by intrahousehold dynamics these notions are then explored empirically using husbands and wives individual perceptions of their access to credit in rural paraguay the most significant empirical findings of the paper are that i compared to men women are more likely to be credit constrained ii women s rationing status responds to a different set of factors than men s and iii husbands may choose not to intermediate capital to their wives even when they are able to do so results from this exercise provide empirically sound support for the assumptions underlying women targeted credit programs

sustainable urban livelihoods and marketplace social capital crisis and strategy in petty trade urban growth has been accompanied by the development of bimodal labour markets and increasing inequalities in both north and south in southern cities many of the poor have turned to the informal sector in particular to street trade this has resulted in a multiplicity of urban conflicts and has led to pressure on urban managers to undertake formalisation for which an increasingly developmental approach has been advocated nevertheless for traders the formalisation of street trade has very uneven outcomes the starting point for this article is the premise that not enough is known about the social fabric upon which trading careers depend adopting sustainable livelihoods as a conceptual framework and drawing on social capital theory four questions are addressed how do trading careers survive over time are there differences in the survival strategies for which social capital is employed among traders operating in different political cultural and socioeconomic contexts in the new processes of urba

denmark s contribution to the world food programme a success story abstract the danish government has achieved a six fold increase in the number of people who could be fed with danish development food aid from 1990 to 1997 at a reduced total cost a change in the composition of the danish food basket from high value commodities of animal origin toward basic vegetable commodities produced this dramatic increase in the cost effectiveness of denmark s regular contribution to the world food programme the decision to change the food basket was strongly opposed by the very well organized danish meat and dairy industries and their interest organizations notwithstanding the substantial opposition from these organizations the ministry of foreign affairs maintained its commitment to phase animal commodities out of the danish food basket the world food programme was very supportive of denmark s initiative to promote a more flexible approach to the determination of donor food baskets the outstanding partnership between the ministry of foreign affairs and the world food programme has been instrumental in the successful implementation of the new danish food aid policy

disaggregating food consumption parameters designing targeted nutritional interventions abstract this article is concerned with a new nutritional intervention strategy which is based on the belief that malnourished people eat different types of food to the well nourished the calculation of disaggregated food consumption parameters can identify inferior food commodities and the subsidization of these commodities will target intervention to those most in need the effectiveness of this policy depends on the understanding of its theoretical basis the author introduces the policy maker to this by reviewing the theoretical basis for consumption analysis and then several key studies

food policy integrating supply distribution and consumption in many developing countries the persistent problem of hunger calls for policies that encompass not only the production of food but also its distribution and its use by consumers this book brings together the best of current thinking on food policy by specialists in agriculture nutrition management public health education development and other related fields the editors place the individual contributions within the broad framework of food policy topics discussed include world food policy the outcome and effects of programs to increase production trade and food aid domestic marketing price and subsidy policies nutrition growth and disease and food and nutrition policy in the context of existing institutions and competing national priorities experience with food policy in china and in sub saharan africa is reviewed throughout the contribution of women to the household food budget and the impact on women of technological change and agricultural programs receive particular attention this interdisciplinary collection will be of interest both to specialists in the areas covered and to persons interested in development issues and food security

the macroeconomic impact of development aid a critical survey the early literature explained aid s macroeconomic impact in the context of the dual gap model showing a clear link between aid and growth many now believe that the empirical evidence shows there to be no such relationship this paper critically reviews the different theoretical perspectives the dual gap model the savings debate recipient fiscal response and aid as dutch disease and the empirical debates on aid savings and growth the basis for denying a relationship between aid and growth is shown to be weak though more recent areas of research offer promising directions for future work

food demand studies in sub saharan africa a survey of empirical evidence abstract the recent empirical food demand studies on sub saharan africa show significant advances in demand specification and methodology especially in the application of less restrictive and theoretically consistent flexible functional forms the findings to date establish some broad patterns on effect of income household demography and life cycle location and prices on food demand patterns however the numerical values of the demand estimates are less generalizable because of an insufficient number of data points to separate the true demand component from other confounding factors which are linked to differences in modeling and estimation of demand relations the priority for future research is to generate sufficiently detailed demand estimates that have a high utility for disaggregated policy analysis but are based on a theoretically consistent and comparable methodology

projected demand and supply for various foods in west africa implications for investments and food policy abstract this paper a summarizes recent evidence of changes in dietary patterns in the 15 ecowas countries of west africa over the past 30 years and the forces driving those changes in this paper the term west africa refers to the 15 countries that are members of the economic community of west african states ecowas benin burkina faso cape verde cote d ivoire the gambia ghana guinea guinea bissau liberia mali niger nigeria senegal sierra leone and togo b uses expenditure elasticity estimates derived from budget consumption studies in 8 of these countries burkina faso cote d ivoire ghana mali niger nigeria senegal and togo and hypotheses about alternative income growth trajectories to develop scenarios about the evolution of demand for various foods over the period 2010 2040 c compares the projected demand growth with projection of production growth in key commodities to identify potential or increasing demand supply gaps and d derives implications for needed investments and policies regarding different commodities and components of the west african agrifood system including identifying gaps in the current african union led comprehensive africa agriculture development caadp programs the analysis shows that in absolute terms production shortfalls relative to demand for starchy staples particularly rice and wheat will continue to pose a major challenge for ecowas countries in relative terms however imbalances between domestic production and demand will increase more quickly for foods with high income elasticities of demand such as meat dairy products seafood fruits and vegetables and vegetable oils urban demand will grow two to four times faster than rural demand depending on the commodity putting increased pressure on already stressed urban food marketing systems substantial variations in supply demand gaps across countries suggest that more fluid regional trade could help individual countries cope with these challenges the findings also suggest that the focus of food policies in west africa historically on starchy staples particularly cereals needs to broaden to include a range of higher value products for which demand is likely to increase very rapidly in the near future

determinants of the performance of microfinance institutions a systematic review microfinance institutions mfis generally aim at improving the access of the poor to financial services while at the same time being financially sustainable but what do we know about how mfis reach and combine these two goals we carry out a systematic review of close to 170 papers discussing the determinants of the financial and social performance of mfis the review shows that the most important determinants addressed in the literature are mfi characteristics size age and type of organization their funding sources the quality of organizational governance and the mfis external context such as macro economic institutional and political conditions the evidence on these issues is rather mixed moreover the direction of the relationship between these drivers and mfi performance depends on the context particularly the country specific context finally there is a lack of consensus in the literature on the measurement of financial and social performance due to the complexity of the concept we argue that social performance should only be assessed by using a multidimensional perspective this can be done either by applying recent and holistic social performance measures such as the spi4 or at least by using a combination of proxies such as outreach gender and rural measures

the governance of corporate sustainability empirical insights into the development leadership and implementation of responsible business strategy this article explores how corporate governance processes and structures are being used in large australian companies to develop lead and implement corporate responsibility strategies it presents an empirical analysis of the governance of sustainability in fifty large listed companies based on each company s disclosures in annual and sustainability reports we find that significant progress is being made by large listed australian companies towards integrating sustainability into core business operations there is evidence of leadership structures being put in place to ensure that board and senior management are involved in sustainability strategy development and are then incentivised to monitor and ensure implementation of that strategy through financial rewards there is evidence of a willingness to engage and communicate clearly the results of these strategies to interested stakeholders overall there appears to be a developing acceptance amongst large corporations that efforts towards improved corporate sustainability are not only expected but are of value to the business we suggest that this is evidence of a managerial shift away from an orthodox shareholder primacy understanding of the corporation towards a more enlightened shareholder value approach often encompassing a stakeholder orientated view of business strategy however strong underlying tensions remain due to the insistent market emphasis on shareholder value

price dispersion and differentiation in online travel an empirical investigation previous research has examined whether price dispersion exists in theoretically highly efficient internet markets however much of the previous work has been focused on industries with low cost and undifferentiated products in this paper we examine the presence of price dispersion and product differentiation using data on the airline ticket offerings of online travel agents otas we find that different otas offer tickets with substantially different prices and characteristics when given the same customer request some of this variation appears to be due to product differentiation different otas specialize by systematically offering different trade offs between ticket price and ticket quality minimizing the number of connections matching requested departure and return time however even after accounting for differences in ticket quality ticket prices vary by as much as 18 across otas in addition otas return tickets that are strictly inferior to the ticket offered by another ota for the same request between 2 2 and 28 of the time overall this suggests the presence of both price dispersion and product differentiation in the online travel market

are women better bankers to the poor evidence from rural microfinance institutions microfinance institutions mfis provide financial services to the poor and in many ways resemble both banks and non profit organizations many mfis target women because more women than men are poor especially in rural areas studies show that women manage money differently from men and have different leadership styles thus in credit unions and financial firms female and male managers achieve different results in microfinance gender diversity on the board of mfis is beneficial and loans authorized by female loan officers have lower default rates motivated by these findings we ask whether mfis with a female chief executive officer ceo are more efficient at serving the poor without jeopardizing financial sustainability we adapt the banking approach to managerial in efficiency to account for the outreach and sustainability goals of the mfis and evaluate whether mfis outreach efficiency differs by the gender of their respective ceos we estimate a stochastic frontier cost function using the battese coelli 1995 model and the true random effects estimators using panel data from over 250 mfis we find that mfis with female ceos have significantly higher outreach efficiency than mfis with male ceos similar results are found with a two step stochastic frontier approach overall the results suggest that promoting gender diversity at the top levels of mfi management is likely to have both social and financial benefits
