remittances from international migration a comparison of el salvador and nicaragua i use household data from el salvador and nicaragua to examine the determinants of remittances from international migration nearly twice as many households in san salvador the capital of el salvador receive remittances from relatives abroad than do households in managua the capital of nicaragua and of those who receive remittances the average remittances received in san salvador is over double that in managua 119 month to 45 month the difference is explained by differences in the behavioral coefficients and by differences in the self selection bias of those who remit out of the pool of emigrants between the two countries excerpt

the dual structure of incomplete demand systems integrability of incomplete demand systems is discussed the concepts of weak integrability quasi expenditure function quasi indirect utility function and quasi utility function are defined their relationships to the expenditure function indirect utility function and utility function are developed the dual structure of the quasi functions permits exact welfare analysis and reveals the conditional preference structure for the commodities of interest new results relating the uniqueness and exactness of consumer s surplus to the structure of the expenditure and indirect utility functions are obtained

are chinese cities too small this paper models and estimates net urban agglomeration economies for cities economic models of cities postulate an inverted u shape of real income per worker against city employment where the inverted u shifts with industrial composition across the urban hierarchy of cities this relationship has never been estimated in part because of data requirements china has the necessary data and context we find that urban agglomeration benefits are high real incomes per worker rise sharply with increases in city size from a low level they level out nearer the peak and then decline very slowly past the peak we find that a large fraction of cities in china are undersized due to nationally imposed strong migration restrictions resulting in large income losses

the unequal geographic burden of federal taxation in the united states workers in cities offering above average wages cities with high productivity low quality of life or inefficient housing sectors pay 27 percent more in federal taxes than otherwise identical workers in cities offering below average wages according to simulation results taxes lower long run employment levels in high wage areas by 13 percent and land and housing prices by 21 and 5 percent causing locational inefficiencies costing 0 23 percent of income or 28 billion in 2008 employment is shifted from north to south and from urban to rural areas tax deductions index taxes partially to local cost of living improving locational efficiency

who remits an examination of emigration by education level and gender employing data on emigration rates by education level this study finds that primary and secondary qualified emigrants contribute positively and significantly to remittances tertiary qualified emigrants however do not contribute significantly to remittances remittances in turn contribute significantly to home country income there is some evidence of both an altruistic and self interested motive to remit gender disaggregated results suggest that females remit more than males and are more altruistic

what are cities worth land rents local productivity and the total value of amenities abstract this paper models how to use widely available data on wages and housing costs to infer land rents local productivity and the total value of local amenities in the presence of federal taxes and locally produced nontraded goods i apply the model to u s metropolitan areas with the aid of visually intuitive graphs the results improve measures of productivity and feature large differences in land rents wage and housing cost differences across metropolitan areas are accounted for more by productivity than quality of life differences regressions using individual amenities reveal that the most productive and valuable cities are typically coastal sunny mild educated and large

a theory of remittances as an implicit family loan arrangement abstract the idea of an implicit and informal loan agreement between family members to explain migrants remittances is not new but its implications have not been fully explored in the theoretical literature many empirically testable propositions may be derived from this hypothesis when trying to explain why emigrants remit what the time profile of remittances is how it depends on the intent to stay on the expected length of stay and on interest rates what use people make of remittances and how the home family consumption behavior is affected by the economic prospects in the receiving country furthermore this theory yields many interesting policy prescriptions for less developed countries wishing to maximize the remittance flow from emigrants

do remittances facilitate a sustainable current account we examine how workers remittances impact on the current account in doing so we focus on how remittances affect the sustainability rather than the size of current account balances we find that the presence of remittances makes it more likely that exports and imports are cointegrated thereby lending support to current account sustainability furthermore quantile regression analysis suggests that increased remittances are associated with a faster speed of current account adjustment towards long run equilibrium particularly for those countries characterised by already highly persistent current account balances in contrast to a literature that emphasises an adverse dutch disease impact of workers remittances on the real exchange rate in terms of reduced external competitiveness our findings suggest that remittances are actually beneficial to the current account balance

the costs of agglomeration house and land prices in french cities we develop a new methodology to estimate the elasticity of urban costs with respect to city population using french house and land price data after handling a number of estimation concerns we find that the elasticity of urban costs increases with city population with an estimate of about 0 03 for an urban area with 100 000 inhabitants to 0 08 for an urban area of the size of paris our approach also yields a number of intermediate outputs of independent interest such as the share of housing in expenditure the elasticity of unit house and land prices with respect to city population and within city distance gradients for house and land prices

remittances and development in latin america flows of workers remittances have become a major source of external finance for developing countries and are particularly important in latin america and the caribbean where they are estimated to have reached 40 billion in 2004 not surprisingly academics policymakers and development practitioners in general have been devoting increasing attention to the potential development impact that these flows may have on receiving countries this paper contributes to this debate along four dimensions first it reviews the evolution of remittances flows to latin america using balance of payments data and compares these statistics with estimates of remittances income based on household surveys second the paper describes the varying profile of remittances recipients in ten latin american countries third the paper reviews the few macro and microeconomic studies that have estimated the impact of remittances on poverty and inequality finally the paper expands some of the existing works to investigate the extent to which that impact is different in latin america and varies across countries in the region

building the city from slums to a modern metropolis we model the building of a city estimate parameters of the model and calculate welfare losses from institutional frictions encountered in changing land use we distinguish formal and slum construction technologies in contrast to slums formal structures can be built tall are durable and non malleable as the city grows areas are initially developed informally then formally and then redeveloped periodically slums are modelled as a technology choice however institutional frictions in land markets may hinder their conversion to formal usage that requires secure property rights using unique data on nairobi for 2003 and 2015 we develop a novel set of facts that support assumptions of the model estimate all parameters of the model and calculate welfare losses of conversion frictions we track the dynamic evolution of the city and compare it with model predictions in the core city formal sector about a third of buildings were torn down over 12 years and replaced by buildings on average three times higher for slums in older areas near the centre even after buying out slumlords overcoming institutional frictions would yield gains amounting to about 18 000 per slum household 30 times typical annual slum rent payments

guestworker migration remittances and the extended family evidence from pakistan the paper places migration in the context of the extended family it models informal loans between migrant and extended family for financing the costs of international labor migration to show repayments to extended family is important we trace the effects of such loans on migrant savings and remittance to the immediate family we employ a standard life cycle approach which predicts that the demand for extended family financing rises with migration costs and falls with pre migration wealth remittance to the immediate family and savings retained abroad both fall with the pre migration loan these hypotheses are tested using data from a survey of return migrants to pakistan carried out in 1986

migrants remittances and financial development macro and micro level evidence of a perverse relationship financial development is commonly identified as an important condition for fostering investment and economic growth it is also believed that migrants remittances stimulate financial development in the receiving economy contributing indirectly to economic growth we explore the relationship between remittances and financial development using macro and micro level data from cross country panel data we find evidence of a negative relationship between remittances and financial deepening in developing countries using household survey data from a study of migrants remittances in two cis countries azerbaijan and kyrgyzstan we also investigate the relationship between remittances financial intermediation and financial literacy among remittance receiving households while we find some evidence of a positive albeit weak relationship for kyrgyzstan in azerbaijan the relatively more financially developed economy we uncover a strong perverse relationship remittances appear to deter bank intermediation and use of formal banking services possible reasons are explored and areas for further investigation identified

motivations to remit evidence from botswana in this article a theory of motivations to send remittances is described and tested with data from botswana altruism is one of the motivations tested and found to be an insufficient explanation for remittances among migrants in botswana a refinement of the model stipulates a modified altruism or enlightened self interest in this model the relationship between the migrant and family is tempered by an implicit understanding of mutual benefit the household strategy may be to encourage some members to migrate as a means of spreading risk and sharing gains the household strategy is similar to an insurance policy where migration is to places where market potential is high the risks incurred might be high the example is given of migration during a drought in botswana migrant remittances were greater in households with more cattle or households with more to lose drought alone was not statistically related to remittances increases in remittances were related to increased levels of education it is suggested that repayment was the motive for parents investment in migrants education migrants gains are identified as the potential for an inheritance the security of channeling investments through a trusted family member and security in having a home to return to it is pointed out that the altruism and family remittances from urban migration were strategies that bridged the simple dynamic of either urban development or rural development impacting on family welfare it is suggested that household models of economy adopt some measure to express the relationship of household wealth to remittances from urban migrants

remittances and the changing composition of migration remittances are seen as a sustainable source of funding for developing countries during recent decades the level of remittances has increased dramatically and the recent financial crisis has scarcely affected the trend in the same period the structure of international migration flows has changed these flows are now characterised by a growing feminisation and by increasing skill levels in this article we establish a link between these two facts and assess the effect of the change in the structure of migration on the level of remittances we use a recent data set on bilateral remittances and estimate a gravity model in which the gender and education background of migration flows are accounted for we find that remittances are positively associated with the share of female and college educated migrants in particular we argue that the rising share of college educated women has had a significant impact on the increase in remittances

the structure of constant elasticity demand models the demand model with constant price and income elasticities has been used extensively in applied agricultural economics this paper analyzes the structure of incomplete systems of constant elasticity demand functions it is demonstrated that there is a duality theory for incomplete demand systems that is analogous to the duality theory for complete systems this theory permits the recovery of that portion of the direct and indirect preferences pertaining to the goods of interest and we can calculate exact welfare measures for changes in income and in the prices of these goods for an incomplete system of constant elasticity demands the slutsky symmetry restrictions for integrability are presented and the implied structure of the direct and indirect preferences with respect to the prices and goods of interest is derived

product differentiation and the treatment of foreign trade in computable general equilibrium models of small economies this paper examines the treatment of exports and imports and external closure rules adopted in recent single country computable general equilibrium models of small economies the paper presents a simple one sector analytic model which captures the major features of the multi sector counterpart used in applied models the paper derives graphical and algebraic solutions to the model and shows that unlike some earlier external closures this one gives rise to a well behaved price taking economy the model is also useful to illustrate the role of elasticities in popular trade theoretic models that include traded and non traded goods

the economic effects of density a synthesis abstract this paper synthesises the state of knowledge on the economic effects of density we consider 347 estimates of density elasticities of a broad range of outcomes ranging from wages innovation rents various amenities the cost of providing public services transport and environment related outcomes to health and wellbeing more than 100 of these estimates have not been previously published and have been provided by authors on request or inferred from published results in auxiliary analyses we contribute original estimates of density elasticities of 16 distinct outcome variables that belong to categories where the evidence base is thin inconsistent or non existent along with a critical discussion of the quality and the quantity of the evidence base we present a set of recommended elasticities applying them to a scenario that roughly corresponds to an average high income city we find that density seems to be a net amenity that is associated with positive external welfare effects densification policies may be welfare enhancing but the distributional effects may be regressive especially if residents are immobile and housing supply is inelastic

wages rents and the quality of life this study focuses on the role of wages and rents in allocating workers to locations with various quantities of amenities the theory demonstrates that if the amenity is also productive then the sign of the wage gradient is unclear while the rent gradient is positive the theory is extended to include the housing market and nontraded goods these extensions require little modification of the conclusion the empirical work on wages shows that the regional wage differences can be explained largely by these local attributes with the use of site price data implicit prices are estimated and quality of life rankings for the cities are computed

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

spatial wage disparities sorting matters spatial wage disparities can result from spatial differences in the skill composition of the workforce in non human endowments and in local interactions to distinguish between these explanations we estimate a model of wage determination across local labour markets using a very large panel of french workers we control for worker characteristics worker fixed effects industry fixed effects and the characteristics of the local labour market our findings suggest that individual skills account for a large fraction of existing spatial wage disparities with strong evidence of spatial sorting by skills interaction effects are mostly driven by the local density of employment not controlling for worker heterogeneity leads to very biased estimates of interaction effects endowments only appear to play a small role

challenges in quantitative economic analysis in support of multilateral trade negotiations abstract a wide range of economic analysis of agricultural trade liberalization was performed prior to and during the uruguay round of trade negotiations views differ as to the effectiveness of this research although most would agree that it became less relevant as the negotiations progressed this paper reviews the contributions of economists to the trade liberalization debate with an emphasis on the quantitative assessment of multilateral agricultural trade liberalization with a new round of agricultural trade negotiations scheduled to begin in 1999 it is crucial that the quantitative work required to support these negotiations begin in the near future the authors conclude that the uruguay round outcome provides numerous challenges and opportunities in analyzing the traditional agenda of agricultural trade liberalization in addition new issues will be added to the agenda of the next round of negotiations these include trade and the environment competition policy and intellectual property rights it is important that economists begin to develop a research agenda that can address these issues and become activists in addressing these topics in public forums

why is the doha development agenda failing and what can be done a computable general equilibrium game theoretical approach we use a world computable general equilibrium model to simulate 143 potential trade reforms and seek solutions to the issues hampering progress in the doha development agenda dda inside the domain defined by all these possible outcomes we apply the axiomatic theory of bargaining and select the nash solution of cooperative games the solutions vary according to the objective functions adopted by the trade negotiators when real income is the objective and services are excluded or when optimising terms of trade is the objective the nash solution is the status quo trade liberalisation is feasible only when the negotiators focus on national exports or gross domestic product gdp our assessment of some possible solutions reveals that excluding members having a gdp below a certain threshold improves the bargaining process regardless of the governments objective formation of coalition such as the g20 constitutes an option for its members to block outcomes imposed by rich members we also find that side payments may be a solution but represent a very high share of the global income gain

motives for private transfers over the life cycle an analytical framework and evidence for peru abstract this paper tests for the motives for private income transfers we consider two motives altruism and exchange the question of private transfer motives is important because such motivation can influence the effects of public income transfers on the distribution of income using a household survey for peru we find that transfer amounts received increase with recipient pre transfer income which contradicts a key prediction of the strong form of the altruism hypothesis but is consistent with exchange we also find that capital market imperfections are likely to be an important cause of private transfers and that social security benefits crowd out the incidence of private transfers

understanding the city size wage gap in 2000 wages of full time full year workers were more than 30 percent higher in metropolitan areas of over 1 5 million people than rural areas the monotonic relationship between wages and city size is robust to controls for age schooling and labor market experience in this paper we decompose the city size wage gap into various components we propose an on the job search model that incorporates latent ability search frictions firm worker match quality human capital accumulation and endogenous migration between large medium and small cities counterfactual simulations of the model indicate that variation in returns to experience and differences in wage intercepts across location type are the most important mechanisms contributing to the overall city size wage premium steeper returns to experience in larger cities is more important for college graduates while differences in wage intercepts is more important for high school graduates sorting on unobserved ability within education group and differences in labor market search frictions and distributions of firm worker match quality contribute little or slightly negatively to observed city size wage premia in both samples

why do migrants remit this paper examines primary incentives of remitting using estimated bilateral data on remittances this paper demonstrates that a rise in the home remittance receiving country s gross national income gni per capita leads to fewer remittances and that a rise in the host remittance sending country s gni per capita motivates migrants to remit more real exchange rates and real interest rates have no effect on remittances these results indicate that altruism is an important and critical component of motivations behind remittances however altruism alone does not appear to be a sufficient explanation of the motivations behind remittances other incentives such as loan repayment and investment play a non negligible role in this regard as well the degree of altruism is higher for migrants from developing countries in comparison with migrants from developed countries and it is higher when we define remittances as personal transfers rather than personal transfers and compensation of employees the results of the vector error correction model show if remittances deviate from the equilibrium relationship they will eventually revert

the optimal distribution of population across cities abstract we develop an urban model that incorporates 1 heterogeneous sites 2 fiscal and urban externalities and 3 an endogenous number of cities i e the extensive margin of urban development within and across city decreasing returns to scale cause agents to perceive their city as being too large in the socially optimal allocation as a consequence in equilibrium the largest cities on the most amenable sites are undersized whereas the smaller cities on less amenable sites are oversized we propose a test for optimal city size with heterogeneous sites extending the henry george theorem

are the direct and indirect growth effects of remittances significant development economists believe that migrant workers remittances are an important source of funds for long run growth therefore recent studies have investigated the growth effects of remittances and reached different conclusions in many such studies the growth of output is simply regressed on both remittances and the channels through which remittances affect growth thus there is no distinction between the indirect and direct growth effects of remittances and such specifications may give unreliable estimates because of the correlation between the channels and remittances in this paper we make a distinction between the indirect and direct effects of remittances our model is estimated with panel data of 40 high remittance recipient countries and a system gmm panel data estimation method

assessing global computable general equilibrium model validity using agricultural price volatility computable general equilibrium cge models are commonly used for global agricultural market analysis concerns are sometimes raised however about the quality of their output since key parameters may not be econometrically estimated and little emphasis is generally given to model assessment this article addresses the latter issue by developing an approach to validating cge models based on the ability to reproduce observed price volatility in agricultural markets we show how patterns in the deviations between model predictions and validation criteria can be used to identify the weak points of a model and guide development of improved specifications with firmer empirical foundations

comparing supply side specifications in models of global agriculture and the food system this article compares the theoretical and functional specification of production in partial equilibrium pe and computable general equilibrium cge models of the global agricultural and food system included in the agmip model comparison study the two model families differ in their scope partial versus economy wide and in how they represent technology and the behavior of supply and demand in markets the cge models are deep structural models in that they explicitly solve the maximization problem of consumers and producers assuming utility maximization and profit maximization with production cost functions that include all factor inputs the pe models divide into two groups on the supply side 1 shallow structural models which essentially specify area yield supply functions with no explicit maximization behavior and 2 deep structural models that provide a detailed activity analysis specification of technology and explicit optimizing behavior by producers while the models vary in their specifications of technology both within and between the pe and cge families we consider two stylized theoretical models to compare the behavior of crop yields and supply functions in cge models with their behavior in shallow structural pe models we find that the theoretical responsiveness of supply to changes in prices can be similar depending on parameter choices that define the behavior of implicit supply functions over the domain of applicability defined by the common scenarios used in the agmip comparisons in practice however the applied models are more complex and differ in their empirical sensitivity to variations in specification comparability of results given parameter choices is an empirical question to illustrate the issues sensitivity analysis is done with one global cge model magnet to indicate how the results vary with different specification of technical change and how they compare with the results from pe models

the costs of urbanization a four country comparison the author reports on attempts to measure the investment costs of urbanization in egypt pakistan bangladesh and indonesia the egyptian and pakistani studies were national scale studies carried out in 1980 1982 and 1982 1984 respectively the bangladesh and indonesian projects were smaller and were conducted by the author in mid 1984 and early 1985 respectively investment resource pools and population growth parameters to the year 2000 are projected and urbanization costs for approximately the same period are estimated including direct investment costs housing and intra urban infrastructure costs interurban infrastructure costs and growth management costs the projected urbanization costs among the four countries are then compared when urban absorption costs are defined broadly to include job creation costs and interurban infrastructure as well as the more obvious housing and urban service costs it is shown that these costs would eat up huge chunks of the aggregate investment resource pool recurrent elements are the needs to reduce infrastructure and service standards to stimulate domestic savings to augment the resource pool to shift to labor intensive employment strategies to economize on the capital costs of job creation and to reduce urban population pressures e g fertility control programs and improving off farm rural labor absorption excerpt

global models of trade in agriculture and related environmental modelling a review and assessment the continuing process of global integration bears implications for farmers and related supplying and processing industries in all parts of the world but also for the rest of the world economy an assessment of agricultural and trade policy impacts is bound to be complex and is often supported by quantitative modeling analysis this article provides an assessment of the present state of applied modelling in the area of trade and agricultural policies we provide in this paper a comparative assessment of alternative modelling approaches considering a total of 16 partial equilibrium and general equilibrium models the assessment includes theoretical modelling foundations datasets employed and institutional aspects such as model maintenance and dissemination of results a typology of models is provided by structuring the assessment along a clear set of evaluation criteria

remittance receipt and business ownership in the dominican republic using household level data from the dominican communities in the latin american migration project lamp dr7 we examine the links between remittance receipt and business ownership we find that while the existence of a family business attracts remittance inflows these monetary funds are associated with a reduced likelihood of business entrepreneurship these results are consistent with various hypotheses regarding remittances and business investments first remittances may be motivated by the availability of investment opportunities in the home community second remittances may respond to a bequest motive on the part of the emigrant who may wish to lay claim on family assets when returning home lastly remittances may cause an income effect that reduces family labour force participation and correspondingly the likelihood of family run business investments

selection in initial and return migration evidence from moves across spanish cities this paper investigates the sorting of more productive workers into denser cities using administrative data for spain that fol low individuals continuously throughout their working lives migrants who move to denser cities are positively selected in terms of educa tion occupational skills and individual productivity as proxied by pre migration position in the local earnings distribution however not everyone is able to benefit equally from denser cities and this leads to a second round of sorting returnees are not only ex ante less productive than permanent migrants but are also those who following the first move have least boosted up their earnings in denser cities
