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

public sector efficiency evidence for new eu member states and emerging markets in this article we analyse public sector efficiency in the new member states of the eu compared to that in emerging markets after a conceptual discussion of expenditure efficiency measurement we compute efficiency scores and rankings by applying a range of measurement techniques the study finds that expenditure efficiency across new eu member states is rather diverse especially as compared to the group of top performing emerging markets in asia econometric analysis shows that higher income civil service competence and education levels as well as the security of property rights seem to facilitate the prevention of inefficiencies in the public sector

price coherence and excessive intermediation suppose an intermediary provides a benefit to buyers when they purchase from sellers using the intermediary s technology we develop a model to show that the intermediary would want to restrict sellers from charging buyers more for transactions it intermediates with this restriction an intermediary can profitably raise demand for its services by eliminating any extra price buyers face for purchasing through the intermediary we show that this leads to inflated retail prices excessive adoption of the intermediaries services over investment in benefits to buyers and a reduction in consumer surplus and sometimes welfare competition among intermediaries intensifies these problems by increasing the magnitude of their effects and broadening the circumstances in which they arise we discuss applications to payment card systems travel reservation systems rebate services and various other intermediaries jel codes d40 l11 l14 l42

labour migration and social networks participation in southern mozambique this paper investigates how social networks in poor developing settings are affected by migration using a unique household survey from southern mozambique we test the role of labour mobility in shaping participation in groups and interhousehold cooperation by migrant sending households in village economies at origin we find that migration cum remittances boosts household engagement in community based social networks our findings are robust to alternative definitions of social interaction and to endogeneity concerns suggesting that stable migration ties and higher income stability through remittances may decrease participation constraints and increase household commitment in cooperative arrangements in migrant sending communities

a gravity model analysis of international migration to north america this study examines the influence of political economic and demographic factors on the size and composition of migration flows to north america a modified gravity model is specified and adjusted to include immigration regulations and characteristics specific to the origin and destination countries for empirical test of the model the time period of study is from 1976 1986 and 70 countries are covered for a total of 1540 observations of migration flows to canada and the usa the results reveal that the population of origin countries and the income of destination countries are two major determinants of migration to north america high population areas of asia and latin america provided a large share of the immigrants domestic restrictions on political and civil freedom in origin countries are found to significantly impair migration to north america

do workers remittances reduce the probability of current account reversals the authors combine the literature on financial crises in emerging markets and developing economies with that on international migrations by investigating whether the increasingly large flows of workers remittances can help reduce the probability of current account reversals the rationale for this stands in the great stability and low cyclicality of remittances as compared with other private capital flows these properties combined with the fact that remittances are cheap inflows of foreign currencies might reduce the probability that foreign investors suddenly flee out of emerging markets and developing economies and trigger a dramatic current account adjustment the authors find that remittances can have such a beneficial effect in particular they show that a high level of remittances as a ratio of gdp makes the relationship between a decreasing stock of international reserves over gdp and a higher probability of current account crises less stringent the same occurs though less neatly for the positive relationship between an increasing stock of external debt over gdp and the probability of current account reversals the results point also to a threshold effect of remittances the mechanisms just described are in fact much stronger when remittances are above 3 percent of gdp

public and private inputs in aggregate production and growth a cross country efficiency approach in a cross section of oecd countries we replace the macroeconomic production function by a production possibility frontier total factor productivity being the composite effect of efficiency scores and possibility frontier changes we consider for the periods 1970 1980 1990 and 2000 one output gdp per worker and three inputs human capital public physical capital per worker and private physical capital per worker we use a semi parametric analysis computing malmquist productivity indexes and we also resort to stochastic frontier analysis results show that private capital is important for growth although public and human capital also contribute positively a governance indicator a nondiscretionary input explains inefficiency better governance helps countries to achieve a better performance nonparametric and parametric results coincide rather closely on the movements of the countries vis a vis the possibility frontier and on their relative distances to the frontier

productivity growth technical progress and efficiency in their comment subhash c ray and evangelia desli 1997 hereafter rd point out that the specification of the decomposition of the malmquist productivity index used by fare et al 1994 hereafter fgnz is not unique and propose and compute an alternative specification of that decomposition we will discuss additional decompositions at the end of this note but proceed here by comparing the rd decomposition with fgnz based on both conceptual and computational grounds rd provide a discussion of the overall malmquist productivity index including the important issue of when this index is equivalent to the traditional notion of total factor productivity tfp namely under the condition that the reference technology be consistent with constant returns to scale crs as they point out this will yield a measure of tfp even if the true underlying technology is not crs for example both rd and fgnz use the crs reference technology to compute overall malmquist productivity one of the key issues raised is the role of the underlying scale properties of the benchmark technologies used to define and compute both productivity and its components in particular two reference technologies are employed in both rd and fgnz what we refer to as crs and variable returns to scale vrs technologies by construction these technologies are nested the crs technology contains the vrs technology as in figure 1 in rd this nestedness provides the logical basis for our decomposition at a very intuitive level we would argue that these two benchmarks can be used to provide bounds on the underlying true but unknown technology 2 intuitively we see the vrs technology providing a type of convex inner approximation whereas the crs technology provides a type of convex outer approximation thus these two technologies provide alternative benchmarks they do not require that the data satisfy either crs or vrs another possible intuitive interpretation is that the crs captures a perhaps hypothetical long run and the vrs approximates the short run as a reference technology the crs technology has some very useful features for example it captures the notion of maximal

on the competitive effects of price matching policies abstract this paper challenges the conventional wisdom that price matching policies lead to supracompetitive prices by reducing firms incentives to undercut rivals i argue that price matching and price beating policies are more appropriately viewed as a means of price discrimination and develop a model that demonstrates their use as such analysis of this model shows that in contrast to the results of the existing literature price matching and price beating may raise or lower equilibrium prices relative to the equilibrium in which firms may not adopt such policies

price matching guarantees are price matching guarantees anticompetitive we examine the incentives for price matching guarantees in markets where information about prices is costly the conventional explanation of price matching as facilitating cartel pricing finds some theoretical support but our model provides an additional explanation a price matching guarantee may be a credible and easily understood means of communicating to uninformed consumers that a firm is low priced the credibility of the signal is assured by the behavior of informed consumers we contrast the testable implications of our model with those arising from two theories of price matching as anticompetitive and show that available evidence supports the signalling theory

economic growth inequality and poverty estimating the growth elasticity of poverty summary this paper uses a new data set of 126 intervals from 60 developing countries to analyze the growth elasticity of poverty that is how much does poverty decline in percentage terms with a given percentage rise in economic growth the data set is both broader in coverage and more selective in terms of quality controls than those used in the past the study finds that while economic growth does reduce poverty in developing countries the rate of poverty reduction depends very much on how economic growth is defined controlling for changes in income inequality when economic growth is measured by changes in survey mean income consumption the growth elasticity of poverty excluding eastern europe and central asia is 2 79 that is a 10 increase in the survey mean will reduce poverty 1 00 person day by 27 9 but when growth is measured by changes in gdp per capita the growth elasticity of poverty is a statistically insignificant 2 27 which is lower than has previously been estimated

for health strength and daily food the dual impact of remittances and public health expenditure on household health spending and child health outcomes abstractchild and infant mortality in developing countries decreased 33 5 per cent and 30 9 per cent respectively during 1995 2009 while remittances and public health spending more than doubled i examine how remittances and government health spending improve these child health outcomes neither government health spending nor remittances causally affect household health spending public health spending has an insignificant negative impact on mortality the increase in remittances causally accounts for 32 per cent and 37 per cent of the decline in child and infant mortality respectively remittances reduce mortality through improved living standards from the relaxation of households budget constraints

economic effects of migration on the left behind in cambodia abstractusing propensity score matching this study examines the effects of migration on various indicators of household wellbeing in cambodia the results indicate that migration would reduce poverty headcount rate by 3 7 percentage points and decrease the depth of poverty migration is also found to reduce by 5 10 per cent the hours worked by members left behind the impact of migration on labour participation may be however vulnerable to unobservable factors nevertheless the study suggests that important heterogeneous effects which differ from the average impact exist the analysis is conducted separately by internal and international migration

technological change technological catch up and capital deepening relative contributions to growth and convergence we decompose labor productivity growth into components attributable to 1 technological change shifts in the world production frontier 2 technological catch up movements toward or away from the frontier and 3 capital accumulation movement along the frontier the world production frontier is constructed using deterministic methods requiring no specification of functional form for the technology nor any assumption about market structure or the absence of market imperfections we analyze the evolution of the cross country distribution of labor productivity in terms of the tripartite decomposition finding that technological change is decidedly nonneutral and that both growth and bipolar international divergence are driven primarily by capital deepening jel o30 o47 d24

determinants of workers remittances an empirical investigation for a panel of eleven developing asian economies we explore the key motives of migrant workers remittances from abroad for 11 major asian migrant sending countries using panel regressions we find that relative higher growth rate interest rate and capital market returns of home over the host investment financial deepening at home have significant impact on remittance inflows into asia along with higher per capita incomes and international crude oil prices with incorporation of per capita incomes and lagged impact of remittances we observe an emergence of consumption motives to remit therefore we conclude that both investment and altruistic motives are the driving forces for remittances inflows into the asian economies

migrant remittances and fertility abstractthis study examines the role of migrants remittances in developing countries fertility transition employing an unbalanced panel of south asian countries and controlling for various economic and socio demographic factors we find that remittances are significantly associated with a lower number of children born to women of childbearing age this suggests the remittances substitution effect to be at play rather than the income effect and may result from decreased need for children for financing the household s future needs as well as from better access to healthcare and contraceptive methods available to migrant households remittances association with fertility appears to be more important than the transfer of fertility norms from migrants host countries the monetary aspects of international migration may therefore be more important for the region s demographic transition than social remittances

can the world cut poverty in half how policy reform and effective aid can meet international development goals abstract poverty in the developing world will decline by about one half by 2015 if the trends of the 1990s persist most of this poverty reduction will occur in asia however while poverty will decline only slightly in africa effective aid could make a contribution to greater poverty reduction in lagging regions even more potent would be significant policy reform in these countries we develop a model of efficient aid in which flows respond to policy improvements that create a better environment for poverty reduction and effective aid we investigate scenarios of policy reform and efficient aid that point the way to how the world can cut poverty in half in every major region

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

total factor productivity differences appropriate technology vs efficiency abstract recent development and growth accounting studies have established that total factor productivity is an important source of cross country differences in income levels and growth rates this paper makes two contributions first it examines the sensitivity of the development accounting results to the cobb douglas specification of the production function second within the cobb douglas framework it weighs evidence of the two alternative explanations of total factor productivity differences the inefficiency view and the appropriate technology view to accomplish these tasks the world production frontier is estimated using a nonparametric deterministic approach known as data envelopment analysis i find that the fraction of income differences explained by physical and human capital increases from 32 to 55 when departing from the cobb douglas assumption there is also evidence consistent with the appropriate technology view countries with an inadequate mix of inputs are unable to access the most productive technologies moreover the world technology frontier appears to be shifting out faster at input combinations close to that of the rd it explains 43 of output variation in 1995 and its importance has increased over time

can low price guarantees deter entry abstract this paper examines the strategic use of low price guarantees lpgs as an entry deterrent the entire space of contemporaneous lpg messages is partitioned according to their ability to deter entry and or increase the incumbent s profits while most price matching and price beating guarantees cannot deter entry into a perfectly contestable market there do exist special classes of price beating guarantees that enable the incumbent to prevent entry interestingly both price matching and price beating can be a part of the incumbent s strategy in subgame perfect equilibria of the game where the firms choose lpgs from 14 classes defined in the paper

revisiting the threshold effect of remittances on total factor productivity growth in south asia a study of bangladesh and india abstractboth bangladesh and india are among the top recipient of remittances in absolute terms however in relative terms remittances as a per cent of gdp the two countries stand at 6 1 and 2

remittances and public finances evidence from oil price shocks we study the effect of inflowing remittances a major source of capital for many countries on tax revenues and tax policy instrumenting remittances with changes in the oil price interacted with a country s distance to oil producing countries we find that remittances have a large positive effect on vat revenues but no effect on income tax revenues this suggests that remittances often escape the income tax but can be taxed via consumption we further show that tax policy is responsive to shocks in incoming remittances remittances make the adoption of vat systems more likely and they lead to lower vat rates and higher income tax rates

the effects of platform most favored nation clauses on competition and entry abstractin the context of sellers who sell their products through intermediary platforms a platform most favored nation pmfn clause is a contractual restriction requiring that a particular seller will not sell at a lower price through a platform other than the one with which it has the pmfn agreement contractual restrictions observed in markets for e books and travel services among other settings can be viewed as examples of this phenomenon we show that pmfn clauses typically raise platform fees and retail prices and curtail entry or skew positioning decisions by potential entrants pursuing low end business models

harnessing the diaspora dual citizenship migrant return remittances political rights provided to immigrants by host countries have received much attention in the literature less attention however has been paid to the extension of extraterritorial rights by home countries in this article i focus on a common type of right provided by home countries to their expatriates the right of dual citizenship dual citizenship rights i argue help home countries leverage the financial and human resources of their diasporas encouraging both remittances and return migration i test this argument using migrant surveys performed in six host countries and find that migrants from homelands that extend dual citizenship are more likely to both remit and express a desire to return home the micro finding regarding remittances is confirmed using aggregate panel data for a large sample of homelands over the period 1980 2009 the results point to the importance of political rights and policies as extended by the migrant s homeland

is public expenditure productive abstract this paper considers the relationship between aggregate productivity and stock and flow government spending variables the empirical results indicate that i the nonmilitary public capital stock is dramatically more important in determining productivity than is either the flow of nonmilitary or military spending ii military capital bears little relation to productivity and iii a core infrastructure of streets highways airports mass transit sewers water systems etc has most explanatory power for productivity the paper also suggests an important role for the net public capital stock in the productivity slowdown of the last fifteen years

on the robustness of the argument that price matching is anti competitive abstract the existing literature suggests that price matching leads to monopoly prices i show that this argument relies on an arbitrary and unrealistic restriction of the firms strategies in particular if firms may adopt price beating policies the competitive outcome prevails

human capital and convergence a production frontier approach using nonparametric production frontier methods we decompose labor productivity growth into components attributable to technological change shifts in the world production frontier technological catch up movements toward or away from the frontier and physical and human capital accumulation movements along the frontier we find that 1 technological change is decidedly nonneutral 2 productivity growth is driven primarily by physical and human capital accumulation 3 the increased international dispersion of productivity is explained primarily by physical capital accumulation and 4 international polarization the shift from a unimodal to a bimodal distribution is brought about primarily by efficiency changes technological catch up

a model of duopoly and meeting or beating competition this paper analyzes the use of meeting and beating competition clauses in duopoly markets a differentiated products price setting model is considered in which firms have the option of precommitting themselves to contracts which bind their own price to be some prespecified function of their competitor s price the analysis establishes conditions under which these contracts facilitate oligopoly coordination under which they result in price discrimination and under which they can actually be procompetitive

what can new survey data tell us about recent changes in distribution and poverty it has been claimed that in recent times the poor have lost ground both relatively and absolutely even when average levels of living have risen this article tests that claim using household surveys for 67 developing and transitional economies over 1981 94 it finds that changes in inequality and polarization were uncorrelated with changes in average living standards distribution improved as often as it worsened in growing economies and negative growth was often more detrimental to distribution than positive growth overall there was a small decrease in absolute poverty although with diverse experiences across regions and countries almost always poverty fell with growth in average living standards and rose with contraction

international migration and nutritional outcomes in tajikistan abstract tajikistan is the country with the largest share of remittances to gdp in the world at the same time it suffers from stubbornly high levels of child malnutrition against which only very slow progress has been made this paper investigates the relationship between international migration and child malnutrition using data from a recent nationally representative household survey there are theoretical reasons to expect that migration may be exerting both positive and negative effects on nutrition and food security so that understanding what the net effect may be is essentially an empirical question our results indicate that migration appears to be playing a positive role in enhancing child growth patterns as measured by height for age z scores in the country we explore some of the possible channels through which this effect might be operating and find that one such channel is by increasing households kilocalorie consumption

productivity growth technical progress and efficiency change in industrialized countries this paper analyzes productivity growth in 17 oecd countries over the period 1979 1988 a nonparametric programming method activity analysis is used to compute malmquist productivity indexes these are decomposed into two component measures namely technical change and efficiency change we find that u s productivity growth is slightly higher than average all of which is due to technical change japan s productivity growth is the highest in the sample with almost half due to efficiency change jel c43 d24 in this paper we apply recently developed

do remittances diminish social violence abstractthis paper represents the first attempt to formalise the relationship between remittances and social violence by developing a model that predicts that migrants remittances lead to the reduction of social violence in the recipient economy under the condition that remittances increase the average product of labour using homicide data as an indicator of social violence we tested our model s prediction controlling for the endogeneity problem with appropriate instruments we found that remittances tend to reduce social violence we performed sensitivity analysis on remittances in the empirical specification and found it robust with an unchanged negative sign

governance and growth a simple hypothesis explaining cross country differences in productivity growth cross country evidence shows that a subset of developing countries isgrowing very rapidly taking advantage of opportunities to catch up atthe same time that other developing countries are growing slowly we arguethat this is due to differences in the quality of governance inparticular we show that productivity growth is higher in better governedcountries

can high inequality developing countries escape absolute poverty do the poor face the same prospects for escaping poverty in high inequality developing countries as in low inequality countries is it possible for inequality to be so great as to stifle prospects of reducing absolute poverty even when other initial conditions and policies are favorable to growth household survey data for developing countries suggest that initial distribution does affect how much the poor share in rising average incomes higher initial inequality tends to reduce growth s impact on absolute poverty by the same token higher inequality diminishes the adverse impact on the poor of general economic contraction combining this evidence with that from recent investigations of inequality s effect on growth the author finds that if inequality is high enough countries that would have very good growth prospects at low levels of inequality may see little or no overall growth and little progress in reducing poverty or even a worsening on both counts the data the author uses suggest that such cases do occur the precision with which key parameters have been estimated makes it difficult to say with confidence how common such cases are but they appear to be in the minority what appear to be the best available estimates suggest that about one fifth of the spells between surveys he analyzed were cases in which poverty was rising yet positive growth in the mean and hence falling poverty is predicted at zero inequality inequality can be high enough to result in rising poverty despite good underlying growth prospects

platform monopolization by narrow ppc bpg combination booking et al abstract the price parity clauses ppcs that online booking platforms impose have come under antitrust scrutiny wang and wright 2017 show how by preventing showrooming a narrow ppc can reduce search costs and benefit consumers under between platform competition in response to having to give up its wide ppc to hotels booking com emphasized its best price guarantee bpg to customers we observe that a narrow ppc combined with a low hassle costs bpg leaves only wang and wright s price parity and monopoly equilibrium ppme in which consumers are worse off than with no platform operating at all a more efficient incumbent platform can deter entry with the bpg while the narrow ppc eliminates competition from direct sales channels an equally efficient platform could enter and compete consumer prices down because of the existence of hassle costs yet this equilibrium is fragile to network effects if sellers have incentives not to price differentiate between platform s and their direct sales channel a narrow ppc alone suffices to sustain the ppme in both cases the detrimental pricing contract combination that we point out calls for different platform competition policy
