unemployment in south africa the nature of the beast abstract unemployment in south africa is so widespread that it demands an explanation this paper examines a central question about south african unemployment why do the unemployed not enter the informal sector as is common in other developing countries the data do not support the idea that unemployment is largely voluntary the policy implications that government should diminish labor market segmentation and the obstacles to entering the productive informal sector may be relevant also to other developing countries with high unemployment

the gender gap fertility and growth changes in fertility have long been recognized as important correlates of economic growth with the relationship between the level of fertility and the level of income per capita being one of the strongest observable correlations in cross country data this paper examines the linkages between fertility and growth theory the structure of the model is presented in sections on production couples decision making system dynamics and steady state equilibria the first component of the model is that increases in capital per worker raise womens relative wages since capital is more complementary to womens labor input than to mens the second component is that increasing womens relative wages reduces fertility by raising the cost of children more than household income finally lower fertility raises the level of capital per worker a positive feedback loop generates demographic transition a rapid decline in fertility accompanied by accelerated output growth

can multinational enterprises light up developing countries evidences from the access to electricity in sub saharan africa summary this paper examines the role that multinational enterprises mnes and foreign direct investments fdi can have in enhancing the access to electricity for local communities in developing countries based on the quality of home and host institutions access to electricity is a marker for development but it is far from being universal in developing countries the shortage of electricity is mainly the consequence of inability of governments in planning financing and developing necessary electricity infrastructure in this context investments from other actors can be essential particularly we focus on the role of fdi and mnes we claim that when mnes invest in developing countries they are incentivized to solve the lack of electricity infrastructure mainly for two reasons to guarantee their business activities and to gain legitimacy with their local stakeholders in addition we argue that mnes and fdi from institutionally underdeveloped countries will be more prone to develop infrastructure for the provision of electricity to local population as generally they suffer from a negative stereotype for this study we rely on 1 547 observations composed of pairs of 83 home countries and 15 host countries in sub saharan africa observed from 2005 to 2011 due to the nature of the database we adopt panel data techniques i e system gmm and corrected least square dummy variable estimators we find that fdi promotes access to electricity in developing countries with weak institutions and this is more likely true when fdi come from institutionally underdeveloped countries these results are far from obvious as they controvert common idea among institutional scholars that a regulatory authority is essential in the provision of infrastructure in conclusion with this paper we partially rehabilitate the image of mnes investing in developing countries by demonstrating that under certain conditions they could contribute to energy poverty alleviation of local population

on the equivalence of import quotas and voluntary export restraint abstract this note re examines the trade effects of a voluntary export restraint and an import quota whether or not they are equivalent in the presence of a dominant monopolist supplier depends fundamentally on the elasticity of a alternative non restricted producers excess supply functions and the market share of the dominant monopolist

the response of the informal sector to trade liberalization this paper studies the relationship between trade liberalization and informality it is often claimed that increased foreign competition in developing countries leads to an expansion of the informal sector defined as the sector that does not comply with labor market legislation using data from two countries that experienced large trade barrier reductions in the 1980 s and 1990 s brazil and colombia we examine the response of the informal sector to liberalization in brazil we find no evidence of a relationship between trade policy and informality in colombia we do find evidence of such a relationship but only for the period preceding a major labor market reform that increased the flexibility of the colombian labor market these results point to the significance of labor market institutions in assessing the effects of trade policy on the labor market

women s work and economic development using a cross country dataset and microdata from india and thailand we examine how women s work status changes with economic development several clear patterns emerge women s labor force participation first declines and then rises with development women move from work in family enterprises to work as paid employees fertility declines and gender gaps in education narrow women s education levels and those of their spouses appear to be important determinants of women s labor market activities broad welfare indicators such as mortality rates and education levels indicate that women s well being improves on average with development both in absolute terms and relative to men

voluntary export restraints and foreign investment abstract this paper develops a model in which both voluntary export restraints vers and foreign investment can be considered we investigate the welfare effect of additional foreign investment under vers it is demonstrated that if the commodity subject to vers is more intensive in capital in the importing country which is assumed to be a debtor country additional foreign investment into that country raises its welfare

the evolution of the racial wage hierarchy in post apartheid south africa this article develops a multilateral decomposition procedure for the analysis of wage differentials and applies this to the evolution of the racial wage hierarchy in south africa over the period 1993 2001 we find evidence that the wage position of the majority african workforce improved relative to all other racial groups immediately following the transition to democratic rule in 1994 but that these gains have been largely eroded in the ensuing years of the post apartheid era we review the range of policy initiatives that have been taken by the government since 1994 in the light of our empirical findings

labor earnings dynamics in a developing economy with a large informal sector abstract we study labor earnings dynamics in a developing economy with a large informal sector we use nationally representative brazilian panel data that cover both formal and informal workers we document large disparities in earnings fluctuations faced by these segments of the labor market as well as the high frequency of transitions between them informality is associated with more volatile earnings while workers in the formal sector are subject to significant downside risk transitions between formal and informal employment bring large asymmetric earnings shocks and have a frequency that depends on age and the initial earnings level

infrastructure quality and the subsidy trap abstract electricity and water are often subsidized in developing countries to increase their affordability for low income households ideally such subsidies would create sufficient demand in poor neighborhoods to encourage private investment in their infrastructure instead many regions receiving large subsidies have precarious distribution networks supplying users who never pay using a structural model of household electricity demand in colombia i predict the change in consumption and profits from upgrading low quality electricity connections i show that the existing subsidies which provide greater transfers to areas with unreliable supply deter investment to modernize infrastructure finally i analyze alternative programs with stronger investment incentives jel h23 h54 l94 l98 o12 o13

electricity planning and implementation in sub saharan africa a systematic review abstract universal electricity access is an important development objective and the focus of a number of key global un initiatives while robust electricity planning is widely believed to be a prerequisite for effective electrification to date no comprehensive overview of electricity planning research has been undertaken on sub saharan africa the world region with the lowest access rates this paper reviews quantitative and qualitative electricity planning and related implementation research considering each of the 49 sub saharan african countries the four regional power pools and the sub continent as a whole applying a broad understanding of electricity planning and a practical limit of 20 reviewed articles per country and region 306 relevant peer reviewed journal articles are included in this review a general classification scheme is introduced that classifies the planning literature along the addressed value chain depth number of different analysed criteria and number of evaluated decision alternatives the literature is found to be strongly clustered in a few countries with less than 5 identified relevant articles in 36 of the 49 countries the total amount of articles per year is clearly increasing over time addressing technology choice operation distribution and implementation analyses although including different high level criteria in analysing electricity systems is common the literature is only starting to use formalised multi criteria decision making mcdm tools the review indicates that 63 of relevant articles favour renewable energy technologies for their given problems frequently mentioned success factors for electrification in sub saharan africa include adequate policy design sufficient finance and favourable political conditions while considerable regional and methodological literature gaps are apparent the literature in this review identifies a rich and fruitful ground for future research to fill these gaps

does electricity reliability matter evidence from rural viet nam abstract using a three round panel dataset of more than 3 000 households the paper estimates the impacts of electricity reliability improvement on the welfare and economic decisions of rural vietnamese households the number of days without power outages in communes per annum is used to proxy for electricity reliability we employ a fixed effect regression with an instrumental variable to deal with the endogeneity issue led by the simultaneous causal relationship between the reliability of electricity and household outcomes along with the unobservable variables we use the similar electricity quality variable but measured in other communes within the same province as an instrumental variable results from this model show that an improvement in electricity reliability plays an important role in enhancing incomes durable consumption access to credit and land investment decisions of rural households

trade liberalization and local labor market adjustment in south africa abstract despite a large literature analyzing trade liberalization in developing countries little evidence exists around its effects in sub saharan african economies characterized by high levels of baseline unemployment and weak manufacturing sectors using a local labor market approach we investigate the causal effects of tariff reforms implemented in south africa between 1994 and 2004 on labor market outcomes at the individual level more specifically we construct a district level measure of exposure to tariff reductions equal to a weighted average of industry tariffs using baseline industry shares as weights and estimate the effect of this shock on local economies we find that workers in districts facing larger tariff reductions experience a significant decline in both formal and informal employment in the tradable sector driven primarily by a decline in manufacturing employment relative to workers in districts less exposed to these reductions there is no evidence of any significant effect on wages for those who remain employed however displaced workers do not show any evidence of transitions into other sectors or migration to less affected regions rather they are more likely to become discouraged workers or exit the labor force entirely and show an increased probability of accessing government transfers

rent control and misallocation rent control is still an important type of government regulation of housing markets in many countries and numerous researchers have studied its implications for allocation welfare and investments in housing the present paper aims to improve our understanding of the effect of second generation rent control when it is applied only to one sector of the rental market it is diagrammatically shown that the welfare effects are very different between a universal and a limited application of rent control studying the danish case of second generation rent control lower rents are found in controlled sectors and a minor increase of the rent in the uncontrolled sector using the area of living space in the dwelling as a measure for housing consumption evidence is also produced of both overallocation and underallocation of housing in the rent controlled sectors as envisaged by economic theory

welfare gains from capital inflows under import quotas abstract the presence of tariffs was assumed in the literature which examined the effect of additional foreign investment on the welfare of the host country in the small country setting however this paper analyzes the case of import quotas and shows that additional inflows of foreign capital improve the host country s welfare when import quotas are kept constant

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

informality and development in developing countries informal firms account for up to half of economic activity they provide livelihood for billions of people yet their role in economic development remains controversial some like hernando de soto 1989 2000 see informal firms as an untapped reservoir of entrepreneurial energy held back by government regulations in this view unleashing this energy by reducing entry regulations or improving property rights would fuel growth and development others like levy 2008 take a more cynical view stressing the advantages enjoyed by informal firms and workers from avoiding taxes and regulations a report from the mckinsey global institute describes informal firms as parasites competing unfairly with law abiding formal firms farrell 2004 in this view informality should be suppressed not unleashed still others follow the development tradition of lewis 1954 harris and todaro 1970 and more recently rauch 1991 and see informality as a byproduct of poverty from this dual perspective formal and informal firms are fundamentally different productive formal entrepreneurs pay taxes and bear the cost of government regulation to reach new customers raise capital and access public goods these entrepreneurs are often educated and find it more profitable to run bigger formal firms rather than the smaller informal ones in contrast informal entrepreneurs are typically uneducated and unproductive and they run small businesses producing low quality products for low income customers using little capital and

the intertemporal evolution of agriculture and labor over a rapid structural transformation lessons from vietnam abstract we combine nationally representative household and labor force survey data from 1992 to 2016 to provide a detailed description of rural labor market evolution and how it relates to the structural transformation of rural vietnam especially within the agricultural sector our study adds to the emerging literature on structural transformation in low income countries using micro level data and helps to answer several policy related questions we find limited employment creation potential of agriculture especially for youth rural urban real wage convergence has gone hand in hand with increased diversification of the rural economy into the non farm sector nationwide and rapid advances in educational attainment in all sectors and regions workforce minimum wage laws seem to have played no significant role in increasing agricultural wages this enhanced integration also manifests in steady attenuation of the longstanding inverse farm size yield relationship farming has remained securely household based and the family farmland distribution has remained largely unchanged small farm sizes have not obstructed mechanization nor the uptake of labor saving pesticides consistent with factor substitution induced by rising real wage rates as rural households rely more heavily on the labor market human capital accumulation rather than land endowments have become the key correlate of improvements in rural household well being

export markets and labor allocation in a low income country we study the effects of a positive export shock on labor allocation between the informal microenterprise sector and the formal firm sector in a low income country the united states vietnam bilateral trade agreement led to large reductions in us tariffs on vietnamese exports we find that the share of manufacturing workers in vietnam in the formal sector increased by 5 percentage points in response to the us tariff reductions the reallocation was greater for workers in more internationally integrated provinces and for younger cohorts we estimate the gap in labor productivity within manufacturing across the informal and formal sectors this gap and the aggregate labor productivity gain from the export induced reallocation of workers across the two sectors are reduced when we account for worker heterogeneity measurement error and differences in labor intensity of production

retail globalization and household welfare evidence from mexico the arrival of global retail chains in developing countries is causing a radical transformation in the way that households source their consumption this paper draws on a new and unique collection of mexican microdata to estimate the effect of foreign supermarket entry on household welfare and its underlying channels the richness of the data allows us to estimate a general expression for the welfare gains from retail fdi and to decompose the total effect into several distinct components to base our estimates on plausibly exogenous variation in foreign retail entry we propose an event study design that exploits data on the universe of foreign store locations and opening dates in combination with high frequency data on barcode level store prices consumption quantities and household incomes in those same locations over the period 2002 2014 we find that foreign retail entry causes large and significant welfare gains for the average household that are mainly driven by a reduction in the cost of living a substantial share of this price index effect is due to pro competitive effects on consumer prices charged by domestic stores we find little evidence of significant changes in average municipality level incomes wages or employment we do however find evidence of store exit and adverse effects on domestic store profits and the incomes of traditional retail sector workers finally we present evidence that the gains from retail fdi are on average positive for all income groups but strongly regressive and quantify the opposing forces that underlie this finding

the political economy of public goods some evidence from india we are interested in how public goods get allocated by a centralized state we use data on public goods and social structure from parliamentary constituencies in rural india to understand the allocation of these goods over the 1970s and 1980s national policies and political agendas during this period emphasized universal access to basic amenities and financed a rapid expansion in rural infrastructure we find evidence of considerable equalization in many of these facilities reflecting perhaps the importance of these commitments among the historically disadvantaged social groups those that mobilized themselves politically gained relative to the others measures of social heterogeneity that have been emphasized in the recent empirical literature on public goods are relevant but not overwhelming in their importance

local governance and the quality of local infrastructure evidence from village road projects in rural china abstract research has shown that allowing local communities to elect their own leaders increases local infrastructure investment however much less is known about the effects of local governance reform on the quality of local infrastructure this paper examines the effects of governance reform implemented in rural chinese villages on the quality of village road projects we conduct surveys in 101 rural villages and collect data related to the implementation of the reform over the last two decades we also measure the quality of over 550 village road projects completed in these villages using fixed effects and instrumental variable estimation methods we find that the implementation of village governance reform increases the quality of village road projects we also find evidence supporting the following effect mechanisms 1 village leaders become younger and more educated 2 high quality road projects increase incumbent leaders re election chances and 3 village residents participate more actively in the management and monitoring of village road projects

engines of liberation electricity was born at the dawn of the last century households were inundated with a flood of new consumer durables what was the impact of this consumer durable goods revolution it is argued here that the consumer goods revolution was conducive to liberating women from the home to analyse this hypothesis a beckerian model of household production is developed households must decide whether or not to adopt the new technologies and whether a married woman should work can such a model help to explain the rise in married female labour force participation that occurred in the last century yes the housewife of the future will be neither a slave to servants nor herself a drudge she will give less attention to the home because the home will need less she will be rather a domestic engineer than a domestic labourer with the greatest of all handmaidens electricity at her service this and other mechanical forces will so revolutionize the woman s world that a large portion of the aggregate of woman s energy will be conserved for use in broader more constructive fields thomas alva edison as interviewed in good housekeeping magazine lv no 4 october 1912 p 436

export share requirements and unemployment the case of quota trade restrictions such as import tariffs have been a common practice for protecting domestic import competing industries in most less developed countries ldcs foreign firms may however circumvent such protection through direct investment in the host countries this is the well known tariff jumping direct foreign investment which has been examined by brecher and diaz alejandro 7 they show that the foreign capital inflow leads to overproduction of the output of tariff protected sectors and hence results in welfare reduction recently rodrik 17 demonstrates that export share requirements when applied to the output produced by foreign capital may offset the negative effect of foreign direct investment through the contraction of tariffprotected overproduced sectors thus an increase in such a requirement may actually improve welfare this result contradicts the earlier finding of davidson matusz and kreinin 11 which is obtained from a partial equilibrium framework the existing literature on export share requirements remains deficient in two respects first the full employment models have been deployed ignoring the fact that most ldcs suffer from massive unemployment second the analysis has been confined by and large to tariff protection thereby neglecting quantitative trade restrictions e g import quotas it is noteworthy that it is quotas rather than tariffs which constitute a major constraint on imports by developing countries 2 the purpose of this paper is thus to remedy these two shortcomings by developing a sectorspecific unemployment general equilibrium model with quota restrictions on imports as noted by richardson 16 export performance requirements operate in a second best environment import

trade liberalization and unemployment theory and evidence from india abstract a widely held view among the public is that trade liberalization increases unemployment using state and industry level unemployment and trade protection data from india we find no evidence of any unemployment increasing effect of trade reforms in fact our state level analysis reveals that urban unemployment declines with trade liberalization in states with flexible labor markets and larger employment shares in net exporter industries moreover our industry level analysis indicates that workers in industries experiencing greater reductions in trade protection were less likely to become unemployed especially in net export industries our results can be explained within a theoretical framework incorporating trade and search generated unemployment and some institutional features of the indian economy

us agricultural exports and labor market adjustments this study empirically investigates the impact of us agricultural exports on farm and nonfarm employment and tests how individuals adjust to agricultural export shocks based on the data from 1991 to 2017 and a bartik style instrument that exploits cross regional variation in agricultural export exposure stemming from initial differences in agricultural specialization and temporal variation in predicted us exports from exogenous tariff reductions we find that a 1 increase in agricultural exports increases farm employment by 0 302 and has no statistically significant impact on nonfarm employment the individual level analysis shows that in response to positive agricultural export demand shocks natives with a college degree are more likely to become self employed and start farm activities and while non natives without a college degree are more likely to become hired farmworkers a back of the envelope calculation based on the estimates of agricultural trade elasticities of employment shows that on balance job gains due to us agricultural exports are slightly larger than job loss due to agricultural imports resulting in a net gain of around 0 24 million farm jobs over 1991 2017

the economic impact of the coal boom and bust in this paper we examine the impact of the coal boom in the 1970s and the subsequent coal bust in the 1980s on local labour markets in kentucky ohio pennsylvania and west virginia we address two main questions in our analysis how were non mining sectors affected by the shocks to the mining sector how did these effects differ between sectors producing local goods and those producing traded goods we find evidence of modest employment spillovers into sectors with locally traded goods but not into sectors with nationally traded goods

sleeping quotas pre emptive quota bidding and monopoly power abstract we rationalize the puzzling existence of binding quotas that are not fully utilized our model has its roots in bhagwati 1965 in r baldwin et al eds trade growth and the balance of payments essays in honor of g haberler mit press new york on tariffs quotas equivalence and is related to the io literature on preemption we study the conditions that lead a monopolist facing a quota restricted market to buy the quota licenses itself and the conditions under which they may remain unused the divisibility of the quota is crucial for the monopolist to pre emptively buy the quota furthermore we study the implications of use it orlose it clauses commonly imposed on auctioned quotas

local natural resource curse abstract utilizing an output based efficiency measure we investigate whether higher public revenues harm efficiency in the production of local public goods much variation in revenues among norwegian local governments can be explained by revenues collected from hydropower production this revenue variation combined with good data availability can be used to address a main concern in the resource curse literature that public sector revenue and in particular the revenue from natural resources is endogenous we obtain an exogenous measure of local revenue by instrumenting the variation in hydropower revenue and thus total revenue by topology average precipitation and meters of river in steep terrain we find support for what we term the paradox of plenty hypothesis that higher local government revenue reduces the efficiency in production of public goods we do not find support for what we term the rentier state hypothesis that revenue derived from natural resources should harm efficiency more than revenue derived from other sources such as taxation

optimal food price stabilization in a small open developing country in poor countries most governments implement policies aiming to stabilize the prices of staple foods which often include storage and trade measures insulating their domestic market from the world market it is of crucial importance to understand the precise motivations and efficiency of those interventions because they can have consequences worldwide this paper addresses those issues by analyzing the case of a small open developing country confronted by shocks to both the crop yield and foreign price in this model government interventions may be justified by the lack of an insurance market for food prices considering this market imperfection the authors design optimal public interventions through trade and storage policies they show that an optimal trade policy largely consists of subsidizing imports and taxing exports which benefits consumers at the expense of producers import subsidies alleviate the non negativity of food storage in other words when stocks are exhausted subsidizing imports prevents domestic price spikes one striking result an optimal storage policy on its own is detrimental to consumers since its stabilizing benefits leak into the world market and it raises the average domestic price by contrast an optimal combination of storage and trade policies results in a powerful stabilizing effect for domestic food prices

on the validity of econometric techniques with weak instruments inference on returns to education using compulsory school attendance laws we evaluate angrist and krueger 1991 and bound jaeger and baker 1995 by constructing reliable confidence regions around the 2sls and liml estimators for returns to schooling regardless of the quality of the instruments the results indicate that the returns to schooling were between 8 and 25 percent in 1970 and between 4 and 14 percent in 1980 although the estimates are less accurate than previously thought most specifications by angrist and krueger 1991 are informative for returns to schooling in particular concern about the reliability of the model with 178 instruments is unfounded despite the low first stage f statistic finally we briefly discuss bias adjustment of estimators and pretesting procedures as solutions to the weak instrument problem

using survey data to assess the distributional effects of trade policy the author develops and applies a methodology to empirically explore the effects of trade policies on the distribution of income and poverty in developing countries he uses a methodology based on two links one connecting trade policies to prices and another connecting prices to household welfare the author applies the methodology to the study of the distributional effects of mercosur on argentine families the main finding is that mercosur benefits the average argentine household across the entire income distribution there is evidence of a pro poor bias of the regional trade agreement on average poor households gain more from the reform than middle income households whereas the effects on rich families are positive but not statistically significant prior to the reform argentine trade policy protected the rich over the poor and after the reform granted some protection to the poor as relative pre mercosur tariffs are higher on relatively skill intensive goods the tariff removals tend to benefit the poor over the rich these findings indicate that trade reforms may actually help improve the distribution of income and reduce poverty in the country

experimental evidence on the economics of rural electrification we present results from an experiment that randomized the expansion of electric grid infrastructure in rural kenya electricity distribution is a canonical example of a natural monopoly experiment

socio economic development and electricity access in developing economies a long run model averaging approach abstract access to electricity continues to be a popular subject in empirical studies however the choice of key factors related to electricity access in the literature to date has been ad hoc due to the lack of a theoretical framework this paper adopts a bayesian model averaging bma approach to selects important factors related to electricity access from 26 socioeconomic indicators using a sample of 48 developing countries and reveal their long term relationship with electricity access the bma approach allows us to identify the optimal empirical model when a theoretical foundation is not available moreover it allows us to address the relative importance of variables using posterior inclusion probabilities and thus has clear policy relevance our results show that access to finance education economic development infrastructure and industrialisation are positively related to electricity access in the long run although the long run relationship does not indicate causality it shows that to maintain this relationship policy adjustments against any deviations from the relationship are needed our study suggests that electrification needs not only economic educational and infrastructural development but also private sector participation governments commitment and political will and integration with poverty reduction and other development schemes

entitled to work urban property rights and labor supply in peru this brief summarizes the results of a gender impact evaluation study entitled entitled to work urban property rights and labor supply in peru new legal rights were issued in 1996 project teams providing titling service through 2003 in peru the study observed that between 1996 and 2003 the peruvian government issued property titles to over 1 2 million urban households the largest titling program targeted at urban squatters in the developing world this paper examines the labor market effects of increases in tenure security resulting from the program pre program squatters in program neighborhoods were significantly more likely to report improved tenure security by 60 percent similarly program participants were 18 8 percentage points less likely to report a high likelihood of eviction or invasion and 18 8 percentage points more likely to report that their dwelling was currently very secure from eviction or invasion the likelihood of working inside the home significantly falls by 11 6 percentage points for the average squatter family with two program periods

time for revisionism on rent control economists traditional hostility to rent contols is based on models that treat the housing market as perfectly competitive and on the experience with hard controls in new york city and many european countries following world war ii the current soft rent control systems in north america are varied and qualitatively different from earlier hard controls the theoretical case against them is weak particularly when the housing market is viewed as imperfectly competitive the empirical case against them is weak too economists should reconsider their blanket opposition to current rent control systems and evaluate them on a case by case basis

gender agricultural production and the theory of the household virtually all models of the household assume that the allocation of resources is pareto efficient within many african households agricultural production occurs on many plots controlled by different members of the household pareto efficiency implies that factors should be allocated efficiently across these plots i find in contrast that plots controlled by women are farmed much less intensively than similar plots within the household controlled by men the estimates imply that about 6 percent of output is lost because of inefficient factor allocation within the household the paper suggests a new approach to modeling intrahousehold allocation consistent with the empirical results

trade liberalization and the skill premium a local labor markets approach trade economists have long studied the effects of globalization on wage differences between workers with different levels of skill or education 1 this literature has generally sought to link globalization to changes in the economy wide skill premium attanasio goldberg and pavcnik 2004 and gonzaga menezes filho and terra 2006 are salient examples that investigate whether changes in sector specific prices or tariffs changes in skill composition within and across sectors and movements in the skill premium are consistent with the predictions of workhorse trade models such as the heckscherohlin model however there is little evidence directly establishing a causal effect of globalization on the skill premium 2 more recently a growing body of research has focused on trade s differential effects across local markets within a country 3 in this paper we combine these two strands of literature by developing a theoretically consistent approach to studying the causal

a note on the nonequivalence of import barriers and voluntary export restraints abstract this paper uses a general equilibrium approach to analyze the consequences of import barriers and voluntary export restraints with respect to international prices and domestic prices under the assumption of perfect competition in all markets it shows that the final outcome with respect to domestic prices depends on the way in which governments allocate the revenue arising from the restrictions the equivalence result obtained by using partial equilibrium is only one of the possible outcomes

the gendered labor market impacts of trade liberalization evidence from brazil this paper investigates gender differences in the impact of brazil s trade liberalization on labor market outcomes to identify the causal effect of trade reforms the paper uses difference in difference estimation exploiting variation across microregions in pre liberalization industry composition the analysis finds that trade liberalization reduced male and female labor force participation and employment rates but the effects on men were significantly larger thereby tariff reductions contributed to gender convergence in labor force participation and employment rates gender differences are concentrated among the low skilled population and in the tradable sector where male and female workers are most likely to be imperfect substitutes

access to water women s work and child outcomes abstractpoor rural women in the developing world spend considerable time collecting water do women living in places where more time is needed for water collection tend to participate less in income earning market based activities do the education outcomes of their children tend to be worse we use micro data for nine developing countries to help address these questions our primary aim is to describe the patterns in the data rather than to infer causality although we do treat the household level access to water as endogenous assuming that community level access is exogenous conditional on a wide range of geographic factors better access to water is not found to be associated with greater off farm paid work but is associated with less unpaid work for women in countries where substantial gender gaps in schooling exist both boys and girls enrollments also tend to be better

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

trade unions v statistical discrimination theory and application to post apartheid south africa a simple model of statistical discrimination is analyzed which captures some stylized facts of the south african labor market it shows that this type of discrimination disappears when the wage rates are determined by efficient bargaining between a representative firm and a union with endogenous membership this may explain why the wage gap between black and white workers in post apartheid south africa is smaller among unionized workers than among non unionized ones

the effects of rural electrification on employment new evidence from south africa this paper estimates the impact of electrification on employment growth by analyzing south africa s mass roll out of electricity to rural households using several new data sources and two different identification strategies an instrumental variables strategy and a fixed effects approach i find that electrification significantly raises female employment within five years this new infrastructure appears to increase hours of work for men and women while reducing female wages and increasing male earnings several pieces of evidence suggest that household electrification raises employment by releasing women from home production and enabling microenterprises migration behavior may also be affected jel h54 l94

rural electrification and household labor supply evidence from nigeria in nigeria the most populated african country rural electrification is a critical issue because of the low household electrification rate and the poor quality of the grid this energy poverty has harmful economic and social consequences in rural areas such as low productivity lack of income generating opportunities and poor housing conditions in this paper we consider electrification as a technical shock that may affect household time allocation using the 2010 2011 general household survey we investigate how electrification affects female and male labor supply decisions within rural households in nigeria focusing on husband wife data we consider potential dependence in spouses labor supply decisions and address the challenge of zero hours of work using a recent copula based bivariate hurdle model deb et al 2013 in addition an instrumental variable strategy helps identify the causal effect of elec trification our results underline that this dependence in spouses labor supply decisions is critical to consider when assessing the impact of electrification on these outcomes electrifi cation increases the working time of both spouses in the separate assessments but the joint analysis emphasizes only a positive effect of electrification on husbands working time in line with the household labor supply approach our findings highlight that within the household the labor supply decisions of one spouse significantly affect those of the other spouse thus if we neglect the effect of electrification on the spouse of the individual examined we may fail to assess how this individual has been actually affected by this common shock on both spouses our results suggest that these within household relationships promote husbands working time at the expense of wives working time

power outages and economic growth in africa abstract this paper estimates the total effect of power outages on economic growth in sub saharan africa over the period 1995 2007 we pay close attention both to potential errors of measurement of african economic growth and to the endogeneity of outages as suggested by henderson et al american economic review 102 2 994 1028 2012 we combine penn world tables gdp data with satellite based data on nightlights to arrive at a more accurate measure of economic growth following andersen et al review of economics and statistics 94 4 903 924 2012 we also employ lightning density as an instrument for power outages our results suggest a substantial growth drag of a weak power infrastructure in sub saharan africa

the effects of partial coverage rent control on the price and quantity of rental housing abstract rent control is widely used but its effects are little understood a two sector model is provided that predicts the effects of rent control on both the price and quantity of rental housing and allows estimates of the size of these effects with limited amounts of data from jurisdictions which have controlled and uncontrolled sectors among other things the model indicates the relationship between the price of rental housing in the absence of rent control and controlled and uncontrolled rent levels under a partial coverage regime

on resolving the dilemma of rent control this research examines the motivations for adopting rent control and discusses a policy alternative designed to respond to the political appeal of rent control while minimising the investment distortion capricious redistribution and administrative complexity of most controls the policy involves limiting regulation to those rents paid by households in the tenant population that are deemed unable to afford adequate housing all rental units in a jurisdiction register their rents with the relevant authority and are assigned a controlled rent landlords must charge the controlled rent only for eligible households but receive the difference between that rent and the market rent from the government the analysis considers the design of such a policy its behavioural incentives and some administrative implications there is also consideration of the appeal of this policy relative to both conventional controls and policies more popular in the literature such as a housing allowance

more on the non equivalence of voluntary export restraints abstract this note demonstrates that vers limiting exporters to a percentage of the domestic market are not equivalent to other trade restrictions and that they can be inferior to equivalent import quotas even when the quota rents accrue to foreign exporters

the employment and wage impact of broadband deployment in canada hundreds of millions of dollars are spent by the canadian federal and provincial governments to subsidize broadband deployment this paper provides the first empirical assessment of the impact of broadband on employment and wage growth in canada variation in elevation explains the regional difference in broadband coverage and is used as an instrument to estimate the causal effect we find that the deployment of broadband in 1997 2011 promoted rural employment and wage growth in service industries goods industries were not impacted the findings suggest that broadband helps service industry businesses overcome geographical barriers that have traditionally hampered rural growth

health externalities of india s expansion of coal plants evidence from a national panel of 40 000 households coal power generation is expanding rapidly in india and other developing countries in addition to consequences for climate change present day health externalities may also substantially increase the social cost of coal health consequences of air pollution have proven important in studies of developed countries but despite clear importance similarly well identified estimates are less available for developing countries and no estimates exist for the important case of coal in india we exploit panel data on indian households matched to local changes in exposure to coal plants increased exposure to coal plants is associated with worse respiratory health consistent with a causal mechanism the effect is specific no effect is seen on diarrhea or fever and no effect on respiratory health is seen of new non coal plants our result is not due to endogenous avoidance behavior or to differential trends in determinants of respiratory health either before the period studied or simultaneously

the demand for food and calories we investigate nutrition and expenditure in rural maharashtra in india we estimate that the elasticity of calorie consumption with respect to total expenditure is 0 3 0 5 a range that is in accord with conventional wisdom the elasticity declines only slowly with levels of living and is far from the value of zero suggested by a recent revisionist literature in these indian data the calories necessary for a day s activity cost less than 5 percent of the daily wage which makes it implausible that income is constrained by nutrition rather than the other way around

prospective analysis of a wage subsidy for cape town youth abstract persistently high youth unemployment is one of the most pressing problems in south africa we prospectively analyze an employer wage subsidy targeted at youth a policy recently enacted by the south african government to address the issue recognizing that a credible estimate of the policy s impact requires a model of the labor market that itself generates high unemployment in equilibrium we estimate a structural search model that incorporates both observed heterogeneity and measurement error in wages using the model to simulate the policy we find that a r1000 month wage subsidy paid to employers leads to an increase of r596 in mean accepted wages and a decrease of 12 percentage points in the share of youth experiencing long term unemployment

rethinking economic development i provide a summary reflection and assessment of the current state of economic development in both the policy and academic worlds in terms of development policy currently the primary focus is on policy interventions namely foreign aid aimed at fixing the deficiencies of developing countries academic research also has a similar focus except with an emphasis in rigorous evaluation of interventions to estimate causal effects a standard set of versatile quantitative tools is used e g experimental and quasi experimental methods which can be easily applied in a range of settings to estimate the causal effects of policies which are typically presumed to be similar across contexts in this article i take a step back and ask whether the current practices are the best that we can do are foreign aid and policy interventions the best options we have for poverty alleviation what else can be done is our current research strategy characterized by rigorous but a lack of context specific analysis the best method of analysis is there a role for other research methods for a deeper understanding of the local context and for more collaboration with local scholars repenser le developpement economiquee dans cet article je propose un apercu une reflexion et une evaluation de l etat actuel du developpement economique a la fois dans les spheres politiques et universitaires en matiere de developpement economique l attention est principalement portee sur l intervention politique c est a dire l aide exterieure visant a corriger les defaillances des pays en developpement les recherches universitaires y portent une attention similaire mais en mettant davantage l accent sur l evaluation rigoureuse de ces memes interventions pour en mesurer les effets de causalite a cette fin un ensemble d outils quantitatifs et modulables standard sont utilises notamment par l entremise de methodes experimentales et quasi experimentales pouvant facilement s appliquer a une vaste gamme de situations et ce aux fins d evaluations des liens de causalite engendres par ces politiques liens habituellement consideres comme similaires d un contexte a l autre dans cet article je prends un peu de recul pour m interroger sur la pertinence des pratiques actuelles les interventions politiques et l aide exterieure offrent elles les meilleures options pour reduire la pauvrete que pouvons nous faire d autre notre strategie de recherche actuelle caracterisee par des analyses rigoureuses mais peu adaptees a des contextes specifiques est elle la meilleure d autres methodes de recherche peuvent elles permettre de mieux comprendre les contextes regionaux et favoriser une meilleure collaboration avec les intellectuels locaux

the price effect of tariff liberalization measuring the impact on household welfare abstract trade policy literature has for many years emphasized open policies positive impact on economic growth and development while these results generally hold when measured on averages empirical evidence suggests that trade liberalization is unlikely to produce beneficial results across all households this study adds to the literature by providing an analysis of the distributive effects of tariff liberalization in mexico the paper examines the effect of tariff liberalization from the perspective of households both as consumers and factor owners allowing for imperfect domestic price transmission the results indicate the overall positive effect of tariff liberalization masks significant differences in the distribution of gains both across income levels and across geographic regions richer households are found to have gained relatively more urban areas as well as mexican states closest to the united states border are also found to be larger beneficiaries while southernmost states have been largely bypassed by the effects of tariff liberalization those results can be explained not only in relation to the different endowments of the households but also by the diverse effects on local prices that has resulted from mexican trade liberalization

career and marriage in the age of the pill genuine change in the economic and social status of u s women did not emanate simply from their increased labor force participation but rather from their increase in professions and as career women those changes first began in the late 1960 s and early 1970 s we examine here one factor of momentous importance in this break with the past the economist 31 december 1999 recently named it the greatest science and technology advance in the twentieth century it is the oral contraceptive known worldwide by its moniker the pill in 1960 18 4 percent of professionals were women as were 4 7 percent of high powered professionals by 1998 36 4 percent of professionals and 25 1 percent of the high powered subset were women we explore in this article a series of connections that link the birth control pill to the increase of women in professional occupations our evidence for the impact of the pill relies largely on the timing of various changes changes in laws giving minors certain adult rights and lowering the age of majority enabled young and unmarried women to obtain the pill young women s control over their fertility directly reduced the costs to them of engaging in long term career investments the pill also served to increase the age at first marriage and thus indirectly reduced a potential penalty of delaying marriage to pursue professional education and training all of these changes began in the late 1960 s and early 1970 s the late 1960 s and early 1970 s were years of tumultuous social and political change how can we separate the impacts of affirmative action the resurgence of feminism changes in social norms and abortion reform from the impact of the pill the simple answer is that the timing of several of these changes is far less convincing than is that of the pill in affecting career investment but that is not the complete answer the economic impact of the pill did not occur in isolation legal change made it possible for young women to obtain contraceptives these changes paradoxically did not stem primarily from concerns regarding access to contraception they were instead part of the larger political movement of the 1960 s the pill moreover unleashed social change by enabling an increase in the age at first marriage there is also no doubt that the rebirth of feminism long in the making served to complement and reinforce the pill s impact our argument for the importance of the pill in affecting women s career decisions relies on the correspondence among breaks in various time series and in the logic of the relationships among the pill career and marriage we will begin with the time series on career and marriage which can be viewed as the dependent variables the evidence on the diffusion of the pill the independent variable is taken up next the logic of our argument relating pill use career and marriage follows and finally we present our defense for why we believe the pill packed considerable power in altering the social and economic status of american women

has rural infrastructure rehabilitation in georgia helped the poor this article proposes a research strategy to deal with the scarcity of data on beneficiaries for conducting impact assessments of community level projects community level panel data from a regular household survey augmented with a special community module are used to measure the impact of projects propensity score matched difference in difference comparisons are used to control for time invariant unobservable factors this methodology takes into consideration the purposeful placement of projects and their interactions at the community level this empirical approach is applied to infrastructure rehabilitation projects for schools roads and water supply systems in rural georgia between 1998 and 2001 the analysis produces plausible results regarding the size of welfare gains from a particular project at the village level and allows for differentiation of benefits between the poor and the non poor the findings of this study can contribute to evaluations of the impact of infrastructure interventions on poverty by bringing new empirical evidence to bear on the welfare and equity implications

paving streets for the poor experimental analysis of infrastructure effects abstract we provide the first experimental estimation of the effects of the supply of publicly financed urban infrastructure on property values using random allocation of first time street asphalting of residential streets located in peripheral neighborhoods in mexico we show that within two years of the intervention households are able to transform their increased property wealth into significantly larger rates of vehicle ownership household appliances and home improvements increased consumption is made possible by both credit use and less saving a cost benefit analysis indicates that the valuation of street asphalting as capitalized into property values is about as large as construction costs

public schooling for young children and maternal labor supply as policy makers have sought to reduce the welfare rolls by increasing labor supply among single mothers much attention has been given to the possible role of expanded child care subsidies including direct provision of public preschool at the same time public interest in child care subsidies for two parent households is high for example former vice president gore not long ago proposed to make high quality pre school fully available to every family for every child in every community in america albert gore 1999 in this paper i use 1980 census data to estimate the effect of public school enrollment for a woman s five year old on measures of labor supply and public assistance receipt this approach has two advantages first i am able to estimate the effect of a large implicit child care subsidy 1 second because public kindergarten is universally available to all age eligible children where it is provided selection problems related to means testing do not arise a difficulty with public school enrollment arises because parents may choose to hold their children back a year or enroll them in private school i deal with this issue by using five yearold s quarter of birth qob variables as instruments for public school enrollment status this strategy works because parents ability to enroll a child in public kindergarten in the academic year when the child turns five typically depends on the calendar date of the child s birth 2 in most states children born in the second quarter april 1 june 30 of 1974 will have been eligible to start kindergarten in the fall of 1979 while children born in the first quarter january 1march 31 of 1975 generally will not eligibility for children born between july 1 and december 31 1974 depends on the rules where they live 3

trade wages and the political economy of trade protection evidence from the colombian trade reforms abstract worker industry affiliation plays a crucial role in how trade policy affects wages in many trade models yet most research has focused on how trade policy affects wages by altering the economy wide returns to a specific worker characteristic i e skill or education rather than through worker industry affiliation this paper exploits drastic trade liberalizations in colombia in the 1980s and 1990s to investigate the relationship between protection and industry wage premiums we relate wage premiums to trade policy in an empirical framework that accounts for the political economy of trade protection accounting for time invariant political economy factors is critical when we do not control for unobserved time invariant industry characteristics we find that workers in protected sectors earn less than workers with similar observable characteristics in unprotected sectors allowing for industry fixed effects reverses the result trade protection increases relative wages this positive relationship persists when we instrument for tariff changes our results are in line with short and medium run models of trade where labor is immobile across sectors or alternatively with the existence of industry rents that are reduced by trade liberalization in the context of the current debate on the rising income inequality in developing countries our findings point to a source of disparity beyond the well documented rise in the economy wide skill premium because tariff reductions were proportionately larger in sectors employing a high fraction of less skilled workers the decrease in the wage premiums in these sectors affected such workers disproportionately

evaluating the effects of optimally distributed public programs child health and family planning interventions this paper develops and tests an optimizing model determining the distribution of family planning and health subsidies across heterogeneous households and assesses the biases in cross area estimates of the health effects of such subsidies due to public resource optimization the model incorporates both health externalities and the endogenous response of the size of the recipient population to program subsidies longitudinal data describing child health and publicly provided family planning and health programs in 20 barrios in laguna province in the philippines are used to estimate the effects of such programs on child health and the relationships between the distribution of the programs and preprogram health levels the impact of a program on a particular childs health status is viewed as dependent upon the childs length of exposure to the program a basic feature of the model is the presence of health externalities which is shown to be sufficient along with plausible features of household behavior to make selective subsidization of fertility control either alone or in combination with health investment subsidies pareto efficient the model suggests that subsidization of fertility control is likely to be pareto efficient in the presence of health or human capital externalities when human capital and family size are gross substitutes and or when any per child human capital subsidies may substitute for direct subsidies to health investment and an equalizing distribution of the subsidies the highest family planning subsidies to the lowest health recipient households is efficient when both health and family planning subsidies are used fertility control subsidies minimize the subsidy burden for donors and are highest when total subsidy expenditures per child are greatest

margins of labor market adjustment to trade abstract we use both longitudinal administrative data and cross sectional household survey data to study the margins of labor market adjustment following brazil s early 1990s trade liberalization we document how workers and regional labor markets adjust to trade induced changes in local labor demand examining various adjustment margins including earnings and wage changes interregional migration shifts between tradable and nontradable employment and shifts between formal employment informal employment and non employment our results provide insight into the regional labor market effects of trade and have important implications for policies that address informal employment and that assist trade displaced workers
