the microfinance promise in the past decade microfinance programs have demonstrated that it is possible to lend to low income households while maintaining high repayment rates even without requiring collateral the programs promise a revolution in approaches to alleviating poverty and spreading financial services and millions of poor households are served globally a growing body of economic theory demonstrates how new contractual forms offer a key to microfinance success particularly the use of group lending contracts with joint liability for the most part however high repayment rates have not translated into profits and studies of impacts on poverty yield a mixed picture in describing emerging tensions the paper highlights the diversity of innovative mechanisms beyond group lending contracts the measurement of financial sustainability the estimation of economic and social impacts the costs and benefits of subsidization and the potential to reduce poverty through savings programs rather than just credit the promise of microfinance has pushed far ahead of the evidence and an agenda is put forward for addressing critical empirical gaps and sharpening the terms of policy discussion

the g20 at the cancun ministerial developing countries and their evolving coalitions in the wto in large measure the voice that developing countries were able to exercise in cancun was a result of their effective coalition formation in this paper we present a brief overview of the various coalitions that played an important role at cancun the greater part of this paper focuses on one among these various coalitions the g20 on agriculture the g20 presents an especially fascinating case of a coalition that combined a great diversity of members and apparently incompatible interests all theoretical reasoning and historical precedent predicted that the group would collapse in the endgame and yet the group survived we investigate the sources of the unity of this group and trace them to a process of learning that allowed the group to acquire certain structural features and develop strategies that helped to cement it further while our central dependent variable is the cohesion of the g20 we also address the derivative question of the costs and benefits of maintaining such coalitions the cancun coalitions give us an excellent case of coalitions that managed to retain their cohesion but also ended up with a situation of no agreement rather than a fulfilment of even some of their demands we examine some of the causes behind the impasse in the negotiation process and suggest ways in which future outcomes could be improved

poverty traps and index based risk transfer products summary a growing literature suggests that in low income countries households with few assets can be trapped in chronic poverty this article reviews relevant threads of the poverty traps literature to motivate a description of the opportunities presented by innovative index based risk transfer products these products can be used to address some insurance and credit market failures that contribute to the persistence of poverty among households in low income countries applications are considered at the micro meso and macro levels 2008 elsevier ltd all rights reserved

how can safety nets contribute to economic growth the paper provides an up to date and selective review of the literature on how social safety nets contribute to growth the evidence is carefully chosen to show how safety nets have the potential to overcome constraints on growth linked to market failures and is organized into 4 distinct pathways i encouraging asset accumulation by changing incentives and by addressing imperfections in financial markets caused by constraints in obtaining credit and from information asymmetries overcoming such failures helps households to invest into their human capital or productive assets ii failures in insurance markets especially in low income setting safety nets are assisting in managing risk both ex post and ex ante iii safety nets are overcoming failure to create assets and other local economy complementary factors to household level investments iv safety nets are shown to relax political constraints on policy safety nets have a dual objective of directly alleviating poverty through transfers to the poor and of triggering higher growth for the poor however the trade off between the dual objectives of equity and growth is not eliminated by the potential for productive safety nets this remains critical for designing social policies

countercyclical safety nets for the poor and vulnerable abstract relatively little is known about how government safety net programs insure against low consumption and stabilize asset bases compared to what is known about their role in transferring income the insurance function requires a flexible budget that can be scaled up rapidly to meet unanticipated circumstances safety nets serving an insurance function also differ from other transfer programs in their targeting they need to determine transitory need rather than more chronic correlates of poverty moreover insurance safety nets need a more flexible implementation strategy than do more permanent programs this paper reviews these issues from the perspective of low income countries

economics of alliances the lessons for collective action this essay provides an up to date summary of the findings of the literature on the economics of alliances we show that the study of the economics of alliances has played a pivotal role in understanding and applying public good analysis to real world applications we establish that the manner in which alliances address burden sharing and allocative issues is related to strategic doctrines weapon technology perceived threats and membership composition past contributions are evaluated and areas needing further development are identified the theoretical and empirical knowledge gained from the study of alliances is shown to be directly applicable to a wide range of international collectives

do social protection transfers reduce poverty and vulnerability to poverty in pakistan household level evidence from punjab empirical studies in different developing countries have investigated the impact of social protection sp on ex post poverty however few studies analysed the impact of sp on ex ante vulnerability to poverty vtp this paper contributes to the literature by evaluating the impact of sp on vulnerability to poverty vtp and poverty rates among households in the punjab province of pakistan a hierarchical modelling approach is used to analyse the multiple indicator cluster survey mics 2011 data of about 90 000 households matching methods and simultaneous endogenous switching regression are used to control for potential selection bias and estimate average treatment effects our results show that sp has a positive impact in reducing household poverty and vtp but this impact is mainly driven by a short term flood relief cash transfer programme pension of government employees and households regular purchase from utility store network

absenteeism as a mechanism for approaching an optimal labor market equilibrium an empirical study this research examines absence as a response to a non optimal labor market equilibrium its basic premise is that workers may be using absenteeism to move themselves closer to an optimal equilibrium in situations where due to greater than desiredwork hours the workers marginal rate of substitution of income for leisure mrs is less than the wage rate for the last hour worked this notion is tested for a sample of workers using tobit analysis with individual data from company records on absence and wages and an empirical measure of each worker s mrs the results indicate a significant positive relationship between absence and the difference between a worker s mrs and wage

imitation contagion or exertion using a tax reform to reveal how colleagues sick leaves influence worker behaviour we analyse the social interaction effects in sick leave behaviour in the workplace using high quality norwegian matched employer employee data with detailed individual information on sick leaves during the 2004 2006 period we find that social interaction effects in sick leave behaviour in the workplace do exist and that the effects are noticeable in size the strong relationship between the sick leave rates among colleagues is not solely the result of contagious diseases nor is it caused by improved informational quality or by the increased workload for the non absent workers evidence supports the existence of reciprocal worker behaviour that is unrelated to joint leisure seeking activities

do local officials know something we don t decentralization of targeted transfers in albania abstract albania provides a small amount of social assistance to nearly 20 of its population through a system which allows a degree of community discretion in determining distribution this study indicates that relative to other safety net programs in low income countries social assistance in albania is fairly well targeted to the poor moreover the poverty targeting exceeds that which could be expected on the basis of proxy indicators of targeting alone communes appear to be using local information unlikely to be obtained on the basis of a questionnaire or formula this remains the case conditional on the level of funding allocated from the central government

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

absenteeism and wages abstract we show that for assembly line type production processes a worker s wage is a sharply decreasing function of his probability of being absent absenteeism causes firms to hire redundant workers we also define the marginal product of assembly line workers

revealed community equivalence scales abstract this paper estimates the equivalence scale revealed by discretionary community allocations of welfare benefits to poor households i apply the proposed approach to a subsidized rice program in indonesia in which villages designated program beneficiaries and estimate the equivalence scale implicit in the beneficiaries they selected i find that the revealed community equivalence scale for this program lies much closer to per capita expenditure than traditional demand based equivalence scales particularly in the poorest communities this suggests that per capita expenditure may be closer to how poor communities actually compare households when allocating aid than previously thought

food security and storage in the middle east and north africa in times of highly volatile commodity markets governments often try to protect their populations from rapidly rising food prices which can be particularly harsh for the poor a potential solution for food deficit countries is to hold strategic reserves which can be called on when international prices spike but how large should strategic stockpiles be this paper develops a dynamic storage model for wheat in the middle east and north africa mena region where imported wheat dominates the average diet the paper uses the model to analyze a strategy that sets aside wheat stockpiles which can be used when needed to keep domestic prices below a targeted price this paper shows that if the target is set high and reserves are adequate the strategy can be effective and robust contrary to most interventions strategic storage policies are counter cyclical and when the importing region is sufficiently large a regional policy can smooth global prices this paper shows that this is the case for the mena region nevertheless the policy is more costly than the pro cyclical policy of a targeted intervention that directly offsets high prices with a subsidy similar to food stamps

absenteeism efficiency wages and shirking we investigate the absence behaviour of workers when there is asymmetric information regarding worker health an individual s health is assumed to be private information to that individual and only observable to a third party at cost our aim is to complement the existing largely empirical studies of absence behaviour which have tended to treat the phenomenon exclusively as a labour supply decision on the part of workers cf allen 1981 barmby and treble 1991 barmby orme and treble 1991 and dunn and youngblood 1986 our approach is to draw out the interactive aspects of the employment relationship we assume that workers are ex ante uncertain as to their state of health and supply labour on the basis of an all or nothing utility maximising decision taken once a realisation of this state has been received utility is a function of income leisure and health and workers value leisure more the sicker they are firms are able to exert some control over individual behaviour by monitoring workers and threatening to fire shirkers that is workers absenting themselves with unacceptable sickness our model highlights an efficiency wage effect through which wages may be used as a method of absence control in particular the optimal response of the firm to an increase in the cost of monitoring is to discourage shirking by raising wages furthermore to the extent that

credit programmes for the poor and seasonality in rural bangladesh this article examines the effect of group based credit used to finance self employment by landless households in bangladesh on the seasonal pattern of household consumption and male and female labour supply this credit can help smooth seasonal consumption by financing new productive activities whose income flows and time demands do not seasonally covary with the income generated by existing agricultural activities the results based upon 1991 92 survey data strongly suggest that an important motivation for credit programme participation is the need to smooth the seasonal pattern of consumption and male labour supply it is only the extent of lean season consumption poverty that selects household into these programmes in addition the largest female and male effects of credit on household consumption are during the lean season

public policy markets and household coping strategies in bangladesh avoiding a food security crisis following the 1998 floods abstract at their peak the 1998 floods covered two thirds of bangladesh causing severe damage to the major rice crop and threatening the food security of tens of millions of households in this paper we first highlight the contribution of government policy interventions including trade liberalization in the early 1990s to stabilization of rice markets during and after the flood then using a panel data set covering 750 households in three rounds over a 13 month period we analyze impacts of the flood on household assets consumption and nutritional outcomes finally we present empirical estimates of the contribution of rice market stabilization and government transfers to household food consumption

the price of worker reliability abstract worker absenteeism is costly to firms that use assembly line production processes this paper shows why an assembly line firm may prefer to pay higher average wages and reduce sick pay entitlement relative to firms with constant returns

does food aid really have disincentive effects new evidence from sub saharan africa summary limited empirical evidence exists either to refute or confirm the pervasive belief that food aid has significant disincentive effects on recipient food production using household level data from rural ethiopia we demonstrate that while simple descriptive statistics appear consistent with the disincentive effects hypothesis once one controls properly for the endogeneity of food aid receipt no empirical support remains for the hypothesis that food aid creates disincentive effects among recipient households the macro economic evidence yields similar findings applying vector autoregression methods to national level data controlling for possible confounding variables we find that food aid has no disincentive effect on food production

social protection 2 0 exploring issues evidence and debates in a globalizing world abstract this paper reviews the growing literature on social protection while not new the concept evolved remarkably in recent years it is approached from a multitude of perspectives and intersects with broader bodies of literature particularly around public policy pro poor growth rights humanitarian strategies and aid effectiveness as well as feeding into specific programmatic issues e g conditionality targeting and transfer selection this blend of challenges and approaches has often made debates elusive and polarized the paper examines the evolution and definitions of social protection and unbundles critical policy institutional and implementation quandaries taken together these considerations shape a set of context specific models of social protection the paper s five core conclusions may help chart future directions for social protection research and practice

network structure and the aggregation of information theory and evidence from indonesia abstract we use unique data from over 600 indonesian communities on what individuals know about the poverty status of others to study how network structure influences information aggregation we develop a model of semi bayesian learning on networks which we structurally estimate using within village data the model generates qualitative predictions about how cross village patterns of learning relate to network structure which we show are borne out in the data we apply our findings to a community based targeting program where citizens chose households to receive aid and show that the networks that the model predicts to be more diffusive differentially benefit from community targeting jel d14 d83 d85 i32 o12 z13

child growth shocks and food aid in rural ethiopia this brief summarizes the results of a gender impact evaluation study entitled child growth shocks and food aid in rural ethiopia conducted between 1995 and 1996 in ethiopia the study observed the impact of food aid on child growth and shocks in communities on the child level food aid has a positive significant impact on the growth in height of children the total amount of food aid appears on average to be sufficient to offset the negative effects of plot damage on child growth given the fact there remains a massive amount of child stunting there must be large amounts of mis targeting of aid girls seem to be more resilient to shocks than boys

shirking and employment protection legislation evidence from a natural experiment abstract the italian employment protection legislation was modified in 1990 making more costly for small firms to dismiss employees using a difference in differences estimator to compare absenteeism rates in small and large firms we find a strong increase of shirking in small firms

sick of being unemployed interactions between unemployment and sickness insurance this paper examines the incentive effects of interactions between unemployment insurance ui and sickness insurance si two important components of sweden s social insurance system the main topic is how the sickness report rate among the unemployed is affected by i the limit of 300 workdays for ui benefits and ii the difference in maximum compensation between ui and si benefits results obtained by duration analysis suggest that sick reports increase as the ui benefit expiration date approaches there is also evidence of an incentive effect on the sick report rate because si offers higher compensation than ui

gone fishing reported sickness absenteeism and the weather i introduction the principal agent problem of contracting employee work effort that is imperfectly monitored arises in a number of areas of economic theory including models of remuneration by seniority lazear 1979 involuntary unemployment e g shapiro and stiglitz 1984 performance based pay macleod and malcomson 1998 and labor hoarding depken redmount and snow 2001 given the importance of this mechanism in the theoretical work the empirical research on the agency problem is remarkably scant in part this reflects the limited availability of personnel data as baker and holmstrom argue in their review article internal labour markets too many theories too few facts 1995 but more fundamentally it reflects the inherent difficulty of empirically capturing the employee effort levels that underlie the models using direct measures of employee or firm level productivity is unquestionably the preferred approach but these measures are notoriously problematic and the studies that use them tend to be case studies introducing external validity issues it is also unlikely to isolate the type of malfeasant shirking behavior that concerns variants of the models where the employee effort decision entails disciplinary risk to inform employee incentives to engage in malfeasant behavior economists have relied on two measures employee disciplinary rates e g cappelli and chauvin 1991 ichino and maggi 2000 and absenteeism rates e g arai and thoursie 2005 bradley green and leeves 2007 ichino and riphahn 2005 the difficulty is that disciplinary rates capture only shirking activity that is identified by employers not that which goes undetected while reported absenteeism particularly sickness absenteeism rates may be entirely legitimate one can therefore never be sure whether differences in these rates across workers facing different shirking costs reflect actual shirking activity as opposed to differences in employers willingness or ability to detect and punish shirkers or differences in employee health that may be correlated with these costs in this paper we identify a different type of shirking activity that potentially addresses both of these shortcomings employees misreporting health in order to exploit weather conditions favorable to high utility outdoor recreation 1 we begin by considering a shirking model of sickness absenteeism in which employees marginal utility of outdoor leisure is increasing in the interaction of two state dependent parameters health and outdoor weather quality the intuition being that ideal weather conditions for engaging in outdoor recreation are valued more when one is physically and perhaps also mentally healthy this assumption leads to two main propositions first increases in sickness absenteeism associated with marginal improvements in weather quality reflect the decisions of the inframarginal workers those workers who in the absence of the weather improvement would be present at work who are the healthiest implying an increase in absenteeism that is unambiguously illegitimate second comparing across workers marginal weather improvements should have the largest impact on sickness absenteeism where shirking costs are highest the reason is that where existing incentives to misreport health are the weakest such as where sick pay is not offered or job protection is weak existing sickness absenteeism levels will be lowest and the inframarginal workers will be the healthiest thereby benefitting most from the weather improvement we examine the empirical relevance of these propositions using a two step approach first we construct an index of weather preferences by linking temperature relative humidity precipitation wind speed and cloud cover data to time use data identifying the weekend and weekday evening outdoor recreational activities of employees with regular daytime work schedules we then examine the empirical relation between the resulting index of the recreational quality of the weather hereafter referred to simply as weather quality and the incidence of short term spells of sickness absenteeism reported in survey data comparing the magnitude of this relation across workers facing different levels of sick pay job protection and job finding rates

teams teamwork and absence we argue that firms with interdependent worker productivity team production have a higher cost of absence and as a consequence spend additional resources on monitoring absence as a result firms with team production should have lower absence rates we estimate the determinants of absence for blue collar workers using a sample of german manufacturing establishments workplace teams are used as a proxy for team production the estimates reveal that firms with teams have lower absence rates as do smaller establishments the size effect however is unique to establishments with teams which fits prior theoretical work that has not been previously tested

bargaining coalitions in the wto agricultural negotiations this paper aims to understand the structural features of bargaining coalitions in the doha round of the wto we provide an empirical assessment of the preferences of each negotiating actor considering general economics indicators development levels structure of agricultural sectors and trade policies bargaining coalitions are analysed by grouping countries using a cluster analysis procedure the clusters are compared with existing coalitions in order to assess their degree of internal homogeneity as well as their common interests such a comparison allows the identification of possible defectors i e countries that according to their economic conditions and policies seem to be relatively less committed to the positions of the coalition they join in addition the ex post analysis of the counterfactual coalitions sheds light on the distance between different coalitions as well as between individual countries and the best alternative group available empirical results confirm our research hypothesis clusters of structurally homogeneous countries well represent existing bargaining coalitions in particular the g 20 shows a high degree of internal coherence which in our framework may provide a clue to the sustainability of this coalition and to its relevance in the doha round negotiations

the effects of expanding the generosity of the statutory sickness insurance system summary this article evaluates an expansion of employer mandated sick leave from 80 to 100 of forgone gross wages in germany we employ and compare parametric difference in difference did matching did and mixed approaches overall workplace absences increased by at least 10 or 1 day per worker per year we show that taking partial compliance into account increases coefficient estimates further heterogeneity in response behavior was of great importance there is no evidence that the increase in sick leave improved employee health a finding that supports a shirking explanation finally we provide evidence on potential labor market adjustments to the reform copyright 2013 john wiley sons ltd

interpreting bargaining strategies of developing countries in climate negotiations a quantitative approach despite the efforts made during the last climate conferences cops countries participating in the negotiation process are still far from reaching an agreement on the implementation of a new post kyoto climate regime the growing role played by developing countries in negotiations is one of the main causes behind the deadlock further attention should therefore be paid to the composition of the alliances formed by developing countries in order to better understand the key structural features driving their bargaining positions by applying a cluster analysis this paper aims to investigate the role played by heterogeneity in specific characteristics of developing countries in explaining divergent costs and benefits associated with alternative climate negotiation outcomes by clustering developing countries according to their economic geographic environmental energy and social characteristics the paper presents some considerations on climate political economy strategies in these countries with respect to existing bargaining coalitions
