urbanization and poverty reduction the role of rural diversification and secondary towns a rather unique panel tracking more than 3 300 individuals from households in rural kagera tanzania during 1991 4 2010 shows that about one in two individuals households who exited poverty did so by transitioning from agriculture into the rural nonfarm economy or secondary towns only one in seven exited poverty by migrating to a large city although those moving to a city experienced on average faster consumption growth further analysis of a much larger cross country panel of 51 developing countries cannot reject that rural diversification and secondary town development lead to more inclusive growth patterns than metropolitization indications are that this follows because more of the poor find their way to the rural nonfarm economy and secondary towns than to distant cities the development discourse would benefit from shifting beyond the rural urban dichotomy and focusing instead more on how best to urbanize and develop the rural nonfarm economy and secondary towns

whatever happened to africa s rapid urbanisation it is widely believed that urbanisation is occurring faster in sub saharan africa than anywhere else in the world as migrants move from rural to urban settlements this is a fallacy while the populations of numerous urban areas are growing rapidly the urbanisation levels of many countries are increasing slowly if at all natural increase rather than net in migration is the predominant growth factor in most urban populations african governments policymakers and international donors need to acknowledge fundamental changes in urbanisation trends and respond to the irrefutable messages these impart about urban employment incomes and economic development

the effect of taxes on labor supply in the underground economy this paper uses micro data from a randomized survey carried out in the metropolitan area of quebec city canada to analyze the decision to evade taxes and work in the underground economy the results indicate that taxes distort labor market activities away from the regular sector to the underground sector but the distortion is small for the average worker the distortion is large however for particular groups of the population such as welfare claimants copyright 1994 by american economic association

poverty under the kuznets process the object of this paper is to investigate the behaviour of poverty indices during the course of development since development is a complex process one cannot hope to capture in a single model all its different facets thus for example the famous lewis 1954 model although it highlights the role of surplus labour in fixing the supply price of labour to the industrial sector assumes identical real incomes for workers in the rural and urban sectors so that it is not rich enough to provide a vehicle for analysing inequality or poverty an alternative model which also focuses on the transfer of population from the rural to the urban sector in the course of development but nevertheless permits the analysis of distributional change is that due to kuznets 1955 in the simplest version of the kuznets process the population is seen as composed of two distributions a high mean income but high inequality distribution in the urban sector and a low mean income and low inequality distribution in the rural sector and the process of development is characterised as an increase in the population share of the urban sector it is from the workings of such a process that kuznets 1955 hypothesised his famous inverse u relation between inequality and development which we have analysed elsewhere anand and kanbur 1981a our object here is to extend this analysis to an investigation of poverty under the kuznets process while the kuznets model permits an analysis of distributional change it suffers from the drawback that it does not contain an adequate explanation of how and why the population shift takes place we will take up this point later on in this paper where a model of migration is presented which does indeed rationalise the kuznets process section i sets up the kuznets process formally and analyses the behaviour of two classes of poverty indices section ii traces the poverty implications of the todaro 1969 model of migration and arrives at conclusions somewhat different from those of fields 1979 section iii winds up the paper

introduction understanding structural transformation in africa summary the limitations of neo classical growth models have led to a resurgence of interest in dual economy models and structural change structural change entails the movement of labor from low productivity sectors like agriculture into more modern sectors of the economy because the share of the labor force in agriculture is so high in most of sub saharan africa the potential for structural change to lead to growth and poverty alleviation in africa appears to be enormous yet very little of this new literature on structural change focuses on africa this special issue begins to fill that gap the first half of this special issue contains five original contributions that provide new insights with respect to the nature of africa s growth over the past two decades the second half contains six original contributions that examine opportunities for structural transformation in africa

quality and competition in recent years the practitioner literature in operations management has seen a dramatic surge in articles on quality management it reflects the increased emphasis on quality by u s firms which has been attributed largely to increased competition faced by them the question of how quality is influenced by competitive intensity however has not received much attention either in the practitioner or the academic research literatures the notion of competitive intensity itself has not been defined precisely in this paper we develop formal models of oligopolistic competition to investigate whether equilibrium levels of quality increase as competition intensifies we consider three different competitive settings i asymmetric duopolistic competition where the dominant firm s intrinsic demand potential decreases ii a symmetric duopoly where the firms are precluded from cooperating in setting quality levels and iii symmetric oligopolistic competition where the number of firms increases we find that the relation between equilibrium quality and competitive intensity depends on what is understood by increased competition and in addition the relation is contingent on the values of parameters describing the cost and demand structure for the industry

nonfarm income diversification and household livelihood strategies in rural africa concepts dynamics and policy implications abstract asset activity and income diversification lie at the heart of livelihood strategies in rural africa this paper introduces a special issue on the topic income diversification and livelihoods in rural africa cause and consequence of change we concentrate on core conceptual issues that bedevil the literature on rural income diversification and the policy implications of the empirical evidence presented in this special issue

poverty decline agricultural wages and non farm employment in rural india 1983 2004 the authors analyze five rounds of national sample survey data covering 1983 1987 8 1993 4 1999 0 and 2004 5 to explore the relationship between rural diversification and poverty poverty in rural india declined at a modest rate during this period the authors provide region level estimates that illustrate considerable geographic heterogeneity in this progress poverty estimates correlate well with region level data on changes in agricultural wage rates agricultural labor remains the preserve of the uneducated and also to a large extent of the scheduled castes and scheduled tribes although agricultural labor grew as a share of total economic activity over the first four rounds it had fallen back to the levels observed at the beginning of the survey period by 2004 this all india trajectory masks widely varying trends across states during this period the rural non farm sector grew modestly mainly between the last two survey rounds regular non farm employment remains largely associated with education levels and social status that are rare among the poor however casual labor and self employment in the non farm sector reveal greater involvement by disadvantaged groups in 2004 than in the preceding rounds the implication for poverty is not immediately clear the poor may be pushed into low return casual non farm activities due to lack of opportunities in the agricultural sector rather than being pulled by high returns offered by the non farm sector econometric estimates reveal that expansion of the non farm sector is associated with falling poverty via two routes a direct impact on poverty that is likely due to a pro poor marginal incidence of non farm employment expansion and an indirect impact attributable to the positive effect of non farm employment growth on agricultural wages the analysis also confirms the important contribution to rural poverty reduction from agricultural productivity availability of land and consumption levels in proximate urban areas

china s uneven progress against poverty while the incidence of extreme poverty in china fell dramatically over 1980 2001 progress was uneven over time and across provinces rural areas accounted for the bulk of the gains to the poor though migration to urban areas helped the pattern of growth mattered rural economic growth was far more important to national poverty reduction than urban economic growth agriculture played a far more important role than the secondary or tertiary sources of gross domestic product gdp rising inequality within the rural sector greatly slowed poverty reduction provinces starting with relatively high inequality saw slower progress against poverty due both to lower growth and a lower growth elasticity of poverty reduction taxation of farmers and inflation hurt the poor external trade had little short term impact

individual morality and reputation costs as deterrents to tax evasion abstract empirical evidence suggests some taxpayers never evade evasion increases with the tax rate and evasion decisions are interdependent these findings are not easily explained by the existing theory which models evasion as an independently made amoral gamble this paper uses nonpecuniary costs of evasion to reconcile theory with evidence once individuals are assumed to differ by an honesty characteristic taxpayers dichotomise into groups the more honest of which responds to a tax change as the evidence suggests a further extension is to introduce an endogenous reputation cost this suggests a positive relationship between the number of evaders and the tax rate

when is growth pro poor evidence from a panel of countries abstract growth is pro poor if the poverty measure of interest falls according to this definition there are three potential sources of pro poor growth a a high growth rate of average incomes b a high sensitivity of poverty to growth in average incomes and c a poverty reducing pattern of growth in relative incomes i empirically decompose changes in poverty in a sample of developing countries during the 1980s and 1990s into these three components in the medium to long run most of the variation in changes in poverty can be attributed to growth in average incomes suggesting that policies and institutions that promote broad based growth should be central to the pro poor growth agenda most of the remainder of the variation in changes in poverty is due to poverty reducing patterns of growth in relative incomes rather than differences in the sensitivity of poverty to growth in average incomes cross country evidence provides relatively little guidance as to the policies and institutions that promote these other sources of pro poor growth

non farm work and food security among farm households in northern ghana this paper examines the impact of non farm work on household income and food security among farm households in the northern region of ghana we analyze the impact by employing propensity score matching method that accounts for self selection bias the matching results show that participation in non farm work exerts a positive and statistically significant effect on household income and food security status supporting the widely held view that income from non farm work is crucial to food security and poverty alleviation in rural areas of developing countries

the value of big data in servitization abstract servitization has become a pervasive business strategy among manufacturers enabling them to undergird their competitive advantage however it has at least one weakness while it is used worldwide also in economies with lower production costs services in manufacturing are slowly becoming commoditized and will become a necessary though not sufficient condition for reaching an above average competitive advantage consequently in this article we propose a new basis for competitive advantage for manufacturing enterprises called a big data strategy in servitization we scrutinize how manufacturers can exploit the opportunity arising from combined big data and servitization therefore the concept of a big data strategy framework in servitization is proposed the findings are benchmarked against established frameworks in the big data and servitization literature its impact on competitive advantage is assessed through three theoretical perspectives that increase the validity of the results the main finding is that through the proposed strategy new revenue streams can be created while opening the possibility to decrease prices for product services through the proposed strategy manufacturers can differentiate themselves from the ones that are already servitizing this article introduces the possibility of influencing the most important of the five vs in big data value in addition to the other four vs volume variety velocity and verification as in regards to servitization the article adds a third layer of added value information beside the two existing ones product and service the results have strategic implications for managers

tax evasion with labour income allingham and sandmo s 1972 classic paper on tax evasion set out a simple framework for looking at the effects of regular tax parameters and of the structure of penalties on the amount of tax dodging carried out by a tax evader subsequent papers have enriched the basic model of individual behaviour and have attempted to adduce some empirical evidence 2 but with few exceptions the essential nature of the assumed underlying problem has remained the same how much income shall i reveal to the authorities in the face of the known penalties and the known possibility of getting caught whilst this approach is useful for some types of tax evasion by individuals it is clearly inappropriate for others such as the phenomenon of working off the books rather than concealing a portion of a uniform lump of income that is undistinguished as to its source the person cheats the government by taking one or more different jobs either in addition to or as a replacement for his regular employment the income from which is administratively difficult to tax this paper examines the implications of the possible diversity of form of the tax evasion problem for the analysis of the fundamental questions which allingham and sandmo addressed the effect of government instruments on the incentives to participate in legal and illegal work activities to do this we must concentrate on one major development of the original model namely that where income is endogenous in effect we construct a particular version of the analysis of labour supply under uncertainty within which to

direct marketing indirect profits a strategic analysis of dual channel supply chain design the advent of e commerce has prompted many manufacturers to redesign their traditional channel structures by engaging in direct sales the model conceptualizes the impact of customer acceptance of a direct channel the degree to which customers accept a direct channel as a substitute for shopping at a traditional store on supply chain design the customer acceptance of a direct channel can be strong enough that an indepent manufacturer would open a direct channel to compete with its own retailers here direct marketing is used for strategic channel control purposes even though it is inefficient on its own and surprisingly it can profit the manufacturer even when so direct sales occur specifically we construct a price setting game between a manufacturer and its independent retailer direct marketing which indirectly increases the flow of profits through the retail channel helps the manufacturer improve overall profitability by reducing the degree of inefficient price double marginalization while operated by the manufacturer to constrain the retailer s pricing behavior the direct channel may not always be detrimental to the retailer because it will be accompanied by a wholesale price reduction this combination of manufacturer pull and push can benefit the retailer in equilibrium finally we show that the mere threat of introducing the direct channel can increase the manufacturer s negotiated share of cooperative profits even if price efficiency is obtained by using other business practices

the effects of location and sectoral components of economic growth on poverty evidence from indonesia abstract in this paper we investigate the relationship between economic growth and poverty reduction by differentiating growth and poverty into their sectoral composition and urban rural location using data from indonesia we find that rural services growth reduces poverty in all sectors and locations however urban services growth has the largest effect on poverty in most sectors finally we also find that rural agriculture growth strongly reduces poverty in rural areas the largest contributor to poverty in indonesia this implies that while agriculture growth in rural areas still plays a major role in reducing poverty policies that enable strong growth in the services sector in both urban and rural areas would expedite poverty reduction

an industry equilibrium analysis of downstream vertical integration this paper investigates the effect of product substitutability on nash equilibrium distribution structures in a duopoly where each manufacturer distributes its goods through a single exclusive retailer which may be either a franchised outlet or a factory store static linear demand and cost functions are assumed and a number of rules about players expectations of competitors behavior are examined it is found that for most specifications product substitutability does influence the equilibrium distribution structure for low degrees of substitutability each manufacturer will distribute its product through a company store for more highly competitive goods manufacturers will be more likely to use a decentralized distribution system this article was originally published in marketing science volume 2 issue 2 pages 161 191 in 1983

a general equilibrium model for industries with price and service competition this paper develops a stochastic general equilibrium inventory model for an oligopoly in which all inventory constraint parameters are endogenously determined we propose several systems of demand processes whose distributions are functions of all retailers prices and all retailers service levels we proceed with the investigation of the equilibrium behavior of infinite horizon models for industries facing this type of generalized competition under demand uncertainty we systematically consider the following three competition scenarios 1 price competition only here we assume that the firms service levels are exogenously chosen but characterize how the price and inventory strategy equilibrium vary with the chosen service levels 2 simultaneous price and service level competition here each of the firms simultaneously chooses a service level and a combined price and inventory strategy 3 two stage competition the firms make their competitive choices sequentially in a first stage all firms simultaneously choose a service level in a second stage the firms simultaneously choose a combined pricing and inventory strategy with full knowledge of the service levels selected by all competitors we show that in all of the above settings a nash equilibrium of infinite horizon stationary strategies exists and that it is of a simple structure provided a nash equilibrium exists in a so called reduced game we pay particular attention to the question of whether a firm can choose its service level on the basis of its own input characteristics i e its cost parameters and demand function only we also investigate under which of the demand models a firm under simultaneous competition responds to a change in the exogenously specified characteristics of the various competitors by either i adjusting its service level and price in the same direction thereby compensating for price increases decreases by offering improved inferior service or ii adjusting them in opposite directions thereby simultaneously offering better or worse prices and service

smallholder participation in vegetable exports and age disaggregated labor allocation in northern tanzania modern agricultural supply chains have been playing an increasingly important role in developing countries and have had significant effects on rural labor markets this article analyses the effects of smallholder farmer participation in export vegetable supply chains in northern tanzania on both household hired labor demand and off farm labor supply using an age disaggregated approach in our sample neither separability nor exogeneity of smallholder farmer participation in export supply chains can be rejected hence we apply lognormal double hurdle models and find that participation in export supply chains positively affects households decision to hire labor from all age groups we also find that it increases the unconditional overall level of hired labor demand while the age disaggregated analysis shows that these effects mostly benefit rural youth however our sample does not allow us to establish statistically significant evidence of an effect on household off farm labor supply although the point estimates point to nonnegligible positive effect sizes

a welfare economic analysis of labor market policies in the harris todaro model this paper presents a welfare economic analysis of the benefits of various labor market policies in the harris todaro labor market model the policies considered are a policy of modern sector job creation which i call modern sector enlargement msenl a policy of rural development which i call traditional sector enrichment tsenr and a policy of wage limitation in the urban economy which i call modern sector wage restraint mswr first i analyze the inequality effects of these policies i then perform two welfare economic analyses the first based on summary measures of labor market conditions total labor earnings unemployment inequality of labor incomes and poverty rates and the second based on dominance analysis in the labor market in both cases assuming that the costs are borne elsewhere the results of the welfare analyses are compared and it is shown that tsenr unambiguously increases welfare in the labor market using both approaches the other policies yield ambiguous results and no policy is unambiguously welfare decreasing

migration and economic mobility in tanzania evidence from a tracking survey this study explores the extent to which migration has contributed to improved living standards of individuals in tanzania using longitudinal data on individuals the authors estimate the impact of migration on consumption growth between 1991 and 2004 the analysis addresses concerns about heterogeneity and unobservable factors correlated with both income changes and the decision to migrate the findings show that migration adds 36 percentage points to consumption growth during a period of considerable growth in consumption these results are robust to numerous tests and alternative specifications unpacking the findings the analysis finds that moving out of agriculture is correlated with much higher growth than staying in agriculture although growth is always higher in any sector if one physically moves economic mobility is strongly linked to geographic mobility the puzzle is why more people do not move if returns to geographic mobility are high the evidence is consistent with models in which exit barriers are set by home communities through social and family norms that prevent migration of certain categories of people

utility based estimation of labour supply functions in the regular and irregular sectors recent theoretical work on labor supply has shown that the tax and transfer system can induce some individuals to work in the irregular labor market models designed to represent such behavior are unable to sign unambiguously the impact of the marginal tax rate as well as many key exogenous parameters on the hours supplied in the irregular market except under strong restrictions on preferences in this paper the authors estimate a simultaneous labor supply model that allows testing some of the more common assumptions found in the literature using a unique data set on the underground economy of the metropolitan area of quebec city canada estimates of elasticities with respect to predetermined variables are presented moreover they test and empirically reject the assumptions of perfect substitution between regular and irregular work activities as well as additive separability of the utility function copyright 1992 by royal economic society

moving up or moving out insights into rural development and poverty reduction in senegal summary while worldwide progress in poverty reduction has been impressive sub saharan africa is lagging behind with slow growth and a high poverty headcount ratio there are fierce debates on how sub saharan africa can foster pro poor growth and the role of agriculture and small versus large scale farming in poverty reduction we contribute to this debate with micro economic empirical evidence from the senegal river delta an area that recently experienced rapid rural development we use household survey data from two panel rounds in 2006 and 2013 and a cluster analysis to investigate livelihood income and poverty dynamics in the region we find that with 4 3 annual growth in average household income 29 5 percentage points poverty reduction and 4 2 percentage points inequality reduction over the period 2006 13 development in the senegal river delta region has been remarkably pro poor income growth and poverty reduction have been most impressive among households moving into wage employment on large scale horticultural export farms and in an emerging service sector income growth in small scale agriculture and non farm businesses has been more modest but has affected the largest number of households transformation in both farm and non farm sectors has driven rural development in the senegal river delta region and investments in both large and small scale agriculture have contributed importantly to household income growth and poverty reduction our findings imply that foreign investments in large scale commercial and export oriented farming can trigger pro poor growth directly through employment effects and indirectly through investment and consumption linkages with the small scale farm and non farm sector

is there a metropolitan bias the relationship between poverty and city size in a selection of developing countries this paper provides evidence from eight developing countries of an inverse relationship between poverty and city size poverty is both more widespread and deeper in very small and small towns than in large or very large cities this basic pattern is generally robust to the choice of poverty line the paper shows further that for all eight countries a majority of the urban poor live in medium small or very small towns moreover it is shown that the greater incidence and severity of consumption poverty in smaller towns is generally compounded by similarly greater deprivation in terms of access to basic infrastructure services such as electricity heating gas sewerage and solid waste disposal we illustrate for one country morocco that inequality within large cities is not driven by a severe dichotomy between slum dwellers and others robustness checks are performed to assess whether the findings in the paper hinge on a specific definition of urban area are driven by differences in the cost of

process innovation product differentiation and channel structure strategic incentives in a duopoly in this paper we analyze the joint implications of two effects a inserting independent profit maximizing retailers into thechannel system provides buffering to the manufacturers from price competition when their products are highly substitutable and intrachannel contracts are observable as shown by mcguire and staelin 1983 under the assumption of constant marginal production costs and b lack of channel coordination results in a reduction in manufacturer s incentives to invest in efforts to reduce production costs as shown by jeuland and shugan 1983 for the case of bilateral monopoly we show that both these results are robust in the sense that the first holds even in the presence of the vertical externality of manufacturer s effort reduction in a noncoordinated channel and the second holds regardless of the degree of substitutability between the competing channel s products specifically we analyze a four stage game with two manufacturers and two retailers where the intrachannel contracts are linear and observable and manufacturers make investments in process improvements to reduce their production costs we find that the optimal channel structure decision depends on interactions between two parameters the degree of substitutability between products and the level of investments required to achieve production cost reduction these parameters represent what have been widely interpreted in the management literature as the two primary generic strategies that most organizations follow in order to gain competitive advantage cost leadership and product differentiation porter 1980 thus our analysis brings out the strategic and interdisciplinary nature of the channel structure decision that can significantly affect firm profitability our main results are as follows first we find that decentralized noncoordinated channels appear as more profitable equilibrium than integration or perfectly coordinated channels at high product substitutability even when process innovation dimension is accounted for in agreement with the literature however the range of substitutability over which decentralization is an equilibrium strategy is smaller the easier it is to reduce production costs intuitively the easier the cost reduction the larger the cost penalty that the channel incurs as a result of not coordinating investment and pricing decisions between channel members and thus smaller the range over which decentralization is an equilibrium this implies that there is an explicit tradeoff between efficiency and strategic incentives in distribution channel design second we show that decentralized manufacturers invest less in process innovation than integrated manufacturers do regardless of the structure of the competing channel and the degree of substitutability between products consequently a decentralized channel has higher costs charges higher prices and produces lower quantities than an integrated channel does moreover these differences get larger the easier the cost reduction the effect on manufacturer profits however is not that clear manufacturers make higher profits by decentralizing if products are highly substitutable inagreement with mcguire and staelin 1983 and coughlan and wernerfelt 1989 however we also find that the relative profitability of decentralization at high substitutability and of integration at low substitutability increases the easier the cost reduction moreover the range of substitutability over which decentralization is more profitable than integration is itself larger the easier the cost reduction though decentralization is an equilibrium strategy over a smallerrange thus process innovation accentuates the profit difference between integrated and decentralized channels andmakes the prisoner s dilemma situation worse in the choice of distribution channel structure finally we analyze two examples of coordinated decision making in a channel a divisional integrated system and franchising in the first case we find that decentralization can emerge as a unique and more profitable equilibrium at high product substitutability in contrast to mcguire and staelin 1983 in the second case we find that decentralization is not always a unique equilibrium and it is not always more profitable than integration in sharp contrast to the results by coughlan and wernerfelt 1989 thus franchising does not provide a sure way of achieving channel coordination when marginal production costs are not constant in sum this paper highlights the importance of simultaneously considering both the horizontal and the vertical dimensions of interorganizational relations on one hand and on the other paying attention to cross functional interactions across marketing and operational decisions to better understand the underlying incentives that shape firm and market structures conventional focus of marketing on demand side effects and of operations on cost side effects can lead to suboptimal decisions

poverty reduction during the rural urban transformation the role of the missing middle as countries develop they restructure away from agriculture and urbanize but structural transformation and urbanization patterns differ substantially with some countries fostering migration out of agriculture into rural off farm activities and secondary towns and others undergoing rapid agglomeration in mega cities using cross country panel data for developing countries spanning 1980 2004 the analysis in this paper finds that migration out of agriculture into the missing middle the rural nonfarm economy and secondary towns yields more inclusive growth patterns and faster poverty reduction than agglomeration in mega cities this suggests that patterns of urbanization deserve much more attention when striving for faster poverty reduction

the composition of growth matters for poverty alleviation this paper contributes to explain the cross country heterogeneity of the poverty response to changes in economic growth it does so by focusing on the structure of output growth the paper presents a two sector theoretical model that clarifies the mechanism through which the sectoral composition of growth and associated labor intensity can affect workers wages and thus poverty alleviation then it presents cross country empirical evidence that analyzes first the differential poverty reducing impact of sectoral growth at various levels of disaggregation and the role of unskilled labor intensity in such differential impact the paper finds evidence that not only the size of economic growth but also its composition matters for poverty alleviation with the largest contributions from labor intensive sectors such as agriculture construction and manufacturing the results are robust to the influence of outliers alternative explanations and various poverty measures

an economic evaluation of spread on rwanda s rural population abstractsustainable partnerships to enhance rural enterprises and agricultural development spread was a programme to enhance the value chain for commodities in rwanda including coffee the implicit concept was that improving the value chain would increase the incomes for smallholders and hence reduce the poverty rate the results indicate that rwanda coffee prices increased relative to an index price for traded coffee with the implementation of spread in addition the results indicate that participation in the coffee market at this time was associated with higher household income and lower rates of poverty

the evolving role of agriculture in poverty reduction an empirical perspective abstract the role of agriculture in development remains much debated this paper takes an empirical perspective and focuses on poverty as opposed to growth alone the contribution of a sector to poverty reduction is shown to depend on its own growth performance its indirect impact on growth in other sectors the extent to which poor people participate in the sector and the size of the sector in the overall economy bringing together these different effects using cross country econometric evidence indicates that agriculture is significantly more effective in reducing poverty among the poorest of the poor as reflected in the 1 day squared poverty gap it is also up to 3 2 times better at reducing 1 day headcount poverty in low income and resource rich countries including those in sub saharan africa at least when societies are not fundamentally unequal however when it comes to the better off poor reflected in the 2 day measure non agriculture has the edge these results are driven by the much larger participation of poorer households in growth from agriculture and the lower poverty reducing effect of non agriculture in the presence of extractive industries

study on labour supply when tax evasion is an option with box cox functional forms and random parameters labour supply when tax evasion is an option is analysed within a discrete choice framework which incorporates random parameters and box cox functional forms using mixed logit models deviates in parameters and in some cases correlation between alternatives in the evasion group are found to be significant the models utilized yield good predictions in terms of labour supply and taxes paid by nonevaders the goodness of fit and quality of prediction is improved by the introduction of correlation between random coefficients

distribution channel strategies in a mixed market abstract this paper studies equilibrium channel strategies in a mixed market with a public firm and a private firm the public firm is concerned with social welfare while the private firm aims to maximize its own profit each firm decides whether to adopt an integrated or a decentralized channel we examine two standard market competition modes bertrand and cournot within each competition mode we consider two typical vertical contracts wholesale price and two part tariff contracts our results suggest that equilibrium channel structures depend on the market competition mode the vertical contract form and the level of product substitutability specifically the channel strategy of the private firm depends mainly on the vertical contract form under a two part tariff contract the private firm always chooses decentralization under a wholesale price contract the private firm chooses integration for most scenarios except for highly substitutable products under bertrand competition i e under very intense competition the channel strategy of the public firm depends mainly on the competition mode under bertrand competition the public firm always chooses decentralization under cournot competition the public firm always chooses the opposite of the private firm s strategy

why don t we see poverty convergence average living standards are converging among developing countries and faster growing economies see more progress against poverty yet we do not find poverty convergence countries starting with higher poverty rates do not see higher proportionate rates of poverty reduction the paper tries to explain why analysis of a new dataset suggests that at given mean consumption high initial poverty has an adverse effect on consumption growth and also makes growth less poverty reducing thus for many poor countries the growth advantage of starting out with a low mean is lost due to a high incidence of poverty jel d63 i31 i32 o15

pricing policies under direct vs indirect channel competition and national vs store brand competition abstract this paper analyzes channel pricing in multiple distribution channels under competition between a national brand nb and a store brand sb where an nb can be distributed both through a direct channel e channel and an indirect channel local stores but an sb can be distributed only through an indirect channel we first explore cross brand and cross channel pricing policies formulating the problem as a nash pricing game we reach two findings 1 brand loyalty building is profitable for both an nb and an sb and 2 marketing decisions are more restrictive for an nb channel than they are for the sb channel we next assess supply chain coordination and reach two findings 1 wholesale price change does not coordinate the supply chain and 2 an appropriate combination of markup and markdown prices can achieve both supply chain coordination and a win win outcome for each channel

services and the business models of product firms an empirical analysis of the software industry some product firms increasingly rely on service revenues as part of their business models one possible explanation is that they turn to services to generate additional profits when their product industries mature and product revenues and profits decline we explore this assumption by examining the role of services in the financial performance of firms in the prepackaged software products industry standard industrial classification code 7372 from 1990 to 2006 we find a convex nonlinear relationship between a product firm s fraction of total sales coming from services and its overall operating margins as expected firms with a very high level of product sales are most profitable and rising services are associated with declining profitability we find however that additional services start to have a positive marginal effect on the firm s overall profits when services reach a majority of a product firm s sales we show that traditional industry maturity arguments cannot fully explain our data it is likely that changes in both strategy and the business environment lead product firms to place more emphasis on services this paper was accepted by christoph loch r d and product development

competition and cooperation in marketing channel choice theory and application this paper discusses the problem of choosing a vertical marketing channel in a product differentiated duopolistic market firms choose product price and the form of the marketing channel to maximize profits it is shown that integration of the marketing function results in greater price competition and lower prices than does the use of independent marketing middlemen the profitability of reducing price competition by using such middlemen is investigated two hypotheses that integration is negatively associated with the products substitutability and that symmetric channel structures are stable are tested in a preliminary way and supported with survey data from the international semiconductor industry

tax evasion and occupational choice this paper is concerned with the combined effect of tax compliance and tax audit policy on the occupational choice of individuals and on public policy objectives such as tax revenue total production and social welfare individuals are assumed to have a choice between riskless work and a risky entrepreneurial occupation they are only differentiated according to their attitudes towards risk more risk averse individuals go into the safe occupation and less risk averse people become entrepreneurs tax evasion is only accessible to the latter and therefore its control tends to discourage risk taking whether control of tax evasion is desirable for the economy as a whole depends on the objective function of the government it is shown that tax audit policy has conflicting effects on tax revenue per capita income and social welfare these conflicts are illustrated through a numerical example in this paper the emphasis is placed on the clarity and the simplicity of the presentation so as to argue that even though the tax schedule can hardly be differentiated across individuals tax evasion and its control can be used by policymakers to introduce variability in the individual s tax treatment

when is servitization a profitable competitive strategy abstract although servitization has emerged as a new competitive strategy for manufacturers there has been little research about product level servitization we investigate the competition between two channels one separately providing both goods and services and the other providing inseparable servitized goods through a game theoretic approach two critical parameters to understand competition between the two channels will be proposed 1 service dependency a degree of dependency of physical goods upon services and 2 channel substitutability a degree of substitution between conventional channels and servitized one the study reveals that the servitization strategy is a better choice for a manufacturer selling physical goods only when the goods require a higher level of service i e high service dependency and when the competition between the two channels is more severe i e high channel substitutability in addition obtaining cost efficiency is found to be an important factor to achieve higher competitive advantage over the other channel
