temporary foreign workers and firms theory and canadian evidence abstract temporary foreign worker tfw programs have grown considerably in size when uncapped we develop a simple efficiency wage model to explain this phenomenon and examine the empirical evidence for it we also use the model to evaluate the implications of tfw programs for domestic workers in our framework firms that have been unable to find domestic workers may hire tfws at the wage previously advertised to domestic workers due to the lower outside option for tfws than domestic workers tfws will exert more effort for the same wage firms would thus prefer to hire otherwise identical tfws rather than domestic workers our model identifies an unintended consequence of a tfw program since the repercussions of a failed domestic job search are less severe if a tfw may be hired instead firms have an incentive to lower their wage offers made to domestic workers using canadian data we find that relative to domestic workers tfws work longer hours have lower rates of absenteeism and are less likely to be laid off consistent with higher effort in our model moreover for tfws from home countries with a relatively high outside option effort is lower than for tfws from other countries resume travailleurs etrangers temporaires et entreprises theorie et exemple canadien en l absence de plafonnement les programmes de travailleurs etrangers temporaires ptet se sont considerablement developpes afin d expliquer ce phenomene et d en examiner les preuves empiriques nous avons developpe un modele simple de salaire d efficience nous avons egalement utilise ce modele pour evaluer l incidence des ptet sur les travailleurs domestiques dans notre cadre d etude les entreprises peinant a trouver une main d uvre locale peuvent embaucher des travailleurs etrangers temporaires au salaire prealablement propose aux travailleurs domestiques compte tenu d options exterieures plus faibles les travailleurs etrangers temporaires deploieront davantage d efforts pour le meme salaire les entreprises prefereront donc embaucher des travailleurs etrangers par ailleurs identiques plutot que des travailleurs domestiques notre modele identifie une consequence inattendue aux ptet etant donne que les consequences d une recherche d employes domestiques infructueuse sont attenuees par l embauche de travailleurs etrangers temporaires les entreprises sont incitees a diminuer les offres salariales proposees aux travailleurs locaux en exploitant les donnees propres au canada nous avons decouvert que les travailleurs etrangers temporaires travaillaient plus d heures avaient des taux d absenteisme inferieurs et etaient moins susceptibles de se faire congedier que les travailleurs domestiques conformement au concept d effort accru developpe dans notre modele en outre pour les travailleurs etrangers temporaires originaires de pays a options exterieures relativement elevees l effort sera moindre que pour ceux provenant d autres pays

electoral outcomes with probabilistic voting and nash social welfare maxima abstract this paper provides unexpected support to nash s view of how bargaining determines the social choice we first present a spatial model of electoral competition with probabilistic voting and a very close relation between voters preferences and their choice probabilities the outcome of the electoral competition game is then shown to be precisely the social alternative that maximizes a nash type social welfare function theorem 1 this electoral outcome is also interpreted as a unanimity likelihood maximum corollary 1 within our framework existence and uniqueness of such an outcome are guaranteed corollaries 2 and 3

the political economy of international factor mobility we model the endogenous determination of policy towards international factor mobility in a common agency setting domestic interest groups bid for protection from the government and the incumbent politicians maximize a welfare function that depends both on domestic voters welfare and contributions collected we characterize equilibrium policies in the price space and show how the degree of complementarity among inputs determines the outcome we establish a similar result for quotas allowing for partial rent capturing for the strategic environment under consideration we also establish a general equivalence result between tariffs and quotas if capturing is complete d 2004 elsevier b v all rights reserved

income redistribution in a common labor market when households are mobile among jurisdictions income redistribution by individual jurisdictions creates fiscal externalities a model of interjurisdictional migration is used to study the nature of this redistributive externality analysis of optimal redistribution and optimal corrective subsidies from higher level governments shows that benefit levels for the recipients of income transfers and tax rates on mobile taxpayers should be equalized across jurisdictions a system of jurisdictions with a common labor market can achieve welfare improvements through coordination of domestic redistributive policy or through the intervention of a higher level government copyright 1991 by american economic association

electoral politics interest groups and the size of government electoral politics interest groups and the size of government i introduction interest groups have been considered main actors in the political drama for some time now by political scientists as in bentley 1908 schattschneider 1935 and truman 1951 and more recently by economist also such as olson 1965 and stigler 1975 despite the widespread consensus on their importance there have been few formal attempts to analyze their impact on public policies thus borooah and van der ploeg 1983 90 were moved to declare that theory based on the importance of different interest groups is badly needed in economics an important exception is becker s 1983 1985 analysis of interest group competition becker draws insights about the nature of the trade offs that occur when interest groups compete for political influence but becker consciously avoids incorporating into his model political institutions such as voting voting rules and candidates 1983 391 4 1985 330 rather he assumes that the political process operates as a veil through which the underlying strengths and demands of various interest groups are revealed this paper takes a different tack but one complementary to becker s approach the analysis is based on an explicit model of the political process that includes interest groups in the model interest group influence is a potential supply of votes for which parties or candidates compete each party seeks a winning coalition of voters and thus engages in implicit logrolling tullock 1959 572 an equilibrium exists in the competition for the support of interest groups and the nature of the equilibrium electoral platforms is identified below embodied in the characterization of the equilibria is a set of parameters that can be said to measure the strengths of the various interest groups and which enable one to identify how candidates change their policy positions in response to a change in the strength of an interest group it is therefore possible to analyze simultaneously the existence of an electoral equilibrium its nature including its normative properties and changes in equilibrium due to shifts in the balance of forces between competing groups 1 in contrast to becker 1983 1985 these analytical features are not assumed outright rather they are based on an underlying model of elections the theoretical underpinnings for this model are discussed in section ii interest groups are often alleged to be responsible in part for recent increases in the size of government in western democracies 2 therefore in sections iii and iv a model of the political process is used to study the impact of an increase in the influence of a particular interest group on government size in the simple models of the public sector considered here increasing group influence per se does not cause the size of the government to increase but an increase in the government s size does result when i there are constraints on the government s ability to change tax shares in response to a shift in group power or ii there is a publicly provided good which benefits one untaxed group and that group s sole concern with government policy is to maximize the amount of the good that it gets the paper concludes by considering some of the normative implications of the results ii interest groups in the electoral process there are two sets of actors in the model parties and interest groups and two sets of relationships which must be analyzed the relationships between interest groups and the parties and the relationship between the parties themselves with respect to the first question this paper investigates the determinants of each interest group s influence on the platforms proposed by the parties with respect to the second it explores whether the competition for votes between the parties produces an equilibrium and if so what its properties are

immigrant specificity and the relationship between trade and immigration theory and evidence studies routinely document that immigrant employment concentrates in non traded goods sectors and that many immigrants have low inter sectoral mobility we consider these observed characteristics of immigrant employment with regard to the question of how immigration affects a nation s pattern of production and trade we model an economy producing three goods one is non traded domestic labor and capital are domestically mobile but internationally immobile allowing that some new immigrants will become specific to the non traded goods sector the model indicates that the effects of immigration on output and trade depend importantly on the sectoral pattern of employment of both new and existing immigrants empirical investigation in a panel data set of oecd countries supports the model s prediction that immigration raises the output of non traded goods consistent with the model we also find that immigration and trade are complements given its empirical support the model s implications for immigration policy are then discussed

the implications of competition among jurisdictions does tiebout need politics the paper investigates whether compensation among local jurisdiction is by itself sufficient to ensure efficient provision of local public goods jurisdictions have fixed boundaries and each has an entrenched government with the power to tax and supply the public good residents can move costlessly among jurisdictions it is shown that competition among numerous jurisdictions is not sificient to guarantee public sector efficiency though residents can vote with their feet land is immobile hence governments can unsurp some land rents for their own ends increasing the number of jurisdictions limits but cannot completely eliminate the ability to exercise discretionary governmental power

illegal immigration and resource allocation this paper studies the effects of illegal immigration and the associated expansion of the underground economy on the allocation of resources commodity prices and wages of workers both in the short run when occupational mobility is restricted and in the long run when the skill composition of the labor force is endogenous the paper goes on to consider some of the fiscal implications of illegal immigration and the related expansion of underground activity effects of sanctions against employers hiring illegal aliens and measures to legalize the status of clandestine foreign workers are also examined the geographical focus is on developed countries primarily the united states and europe excerpt

implications of immigration policies for the u s farm sector and workforce i background in 1942 the united states and mexico signed the bracero program a formal agreement to draw seasonal labor to work in u s agriculture which provided employment opportunities to poor rural mexicans 1 however this program was abolished in 1964 ending the legal seasonal labor supply to u s agriculture in the southwestern states concurrently the united states passed the immigration act of 1965 establishing a quota of 120 000 legal immigrants per year the abandonment of the bracero program the new legal immigrants quota limits and economic inequality between the united states and mexico paved the way for steady entry of illegal laborers and led to eventual insurmountable illegal immigration population in the united states because illegal immigration was not a serious problem in the 1960s and 1970s legislation addressed only the number of legal immigrants allowed to enter the united states but in the 1980s illegal immigration began to emerge as a national problem and extensive debates entrenched around issues such as preventing the entry of unauthorized workers providing public services to illegal immigrants and even legalizing these workers consequently the u s congress attempted to address the immigration problems by enacting the 1986 immigration reform and control act irca the goals of irca were to eliminate the stock of undocumented workers through amnesty 2 and domestic enforcement of employer sanctions and curb the influx of illegal immigrants by increasing the border surveillance amnesty failed to eliminate the stock of illegal immigrants because only about half of the illegal immigrants filed for citizenship and it created future expectation of amnesty and more illegal unauthorized entry furthermore domestic sanctions on employers of undocumented workers and deportation of these workers were scantly enforced to stop the influx of immigrants irca focused heavily on tightening border control the irca also legislated the h 2a program which allowed agricultural employers to bring in guest workers during seasonal operations ers 2007 however farmers complained that the cumbersome paperwork of h 2a and bureaucratic delay were not conducive to procure seasonal laborers at the time of peak farm operations such as vegetable and fruit picking 3 in spite of irca s amnesty provision and strengthened control measures illegal immigration continued to rise about 12 million unauthorized immigrants resided in the united states in 2007 martin 2007 which is reaffirmed by many popular press reports leading to an extended congressional debate that began at the start of this decade to solve the illegal immigration problem several bills were proposed by the house of representatives the senate and the white house addressing issues related to increased domestic and border enforcements 4 paths to citizenship and guest worker programs montgomery 2006 these bills were not passed because of major disagreements among lawmakers over providing citizenship and guest worker programs as a result of the failed legislations and the september 11 attack the government primarily focused on border security accordingly funding for border enforcement has steadily increased 5 and resources were diverted from domestic to border enforcement however boucher and taylor 2007 documented that increased funding to secure the border did not deter undocumented workers from crossing the border because determined immigrants eventually find a way to enter the country by repeated attempts following september 11 2001 the u s immigration and customs enforcement ice further decreased the number of human hours devoted to worksite inspection because monitoring critical infrastructure took priority gao 2005 for example from 1999 to 2003 the number of human hours for domestic enforcement decreased from 480 000 to 18 000 6 7 but by late 2005 the u

fair wages in the open economy we show how an extended theory of fair wages can be incorporated in the two by two heckscher ohlin model an important feature of the model is the existence of involuntary unemployment several results stand out first there is no longer a simple relatio

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

the welfare state migration and voting rights this paper proposes a political economic analysis of public opinion in european union countries toward migrants from poor countries by focusing on redistributive policy the analysis sheds light on specific determinants of public opinion the theoretical analysis based on the median voter framework shows that one of the key variables affecting public opinion is the voting rights of migrants where migrants do not have the right to vote their presence negatively impacts the poorest natives in countries where migrants enjoy voting rights they are able to vote on redistributive policy therefore the impact of migration on natives welfare is fundamentally different after the theoretical analysis the paper proposes an empirical analysis of europeans attitudes toward non western migrants in european union countries this empirical analysis confirms the decisive impact of migrants voting rights it shows that in eu countries the more educated natives are significantly less favorable to migrants from poor countries when the latter have the right to vote

illegal immigration a supply side analysis abstract this paper analyzes the supply side determinants of illegal immigration using a three sector general equilibrium model of the source country agricultural liberalization raises illegal immigration while liberalization of the high tech sector reduces it in contrast capital mobility in the source country renders trade policy ineffective for controlling illegal immigration paradoxically increased enforcement by the host country may raise source country unskilled wages although illegal immigration falls finally under capital mobility a rise in the source country restrictions on capital inflow raises the level of illegal immigration and reduces the effectiveness of border enforcement efforts by the host country

migration unemployment and discrimination abstract this paper uses a dynamic efficiency wage model to analyze the consequences of immigration for a small country when there is discrimination against immigrants in a dual labor market with unemployment discrimination is of the type equal pay for equal work but unequal work which is characteristic of economies with guest worker systems the model exhibits three regimes for rising immigration levels immigration is most beneficial for natives in the intermediate regime an analysis of regime switches shows that changes attributable to globalization and technical progress are consistent with growing opposition to immigration

unemployed immigrants and voter sentiment in the welfare state abstract adverse voter sentiment can arise when immigrants are unemployed and receive tax financed income transfers the explanation for unemployment however determines the consequences for the local population and an efficiency wage explanation for unemployment is consistent with mutual benefit to national workers and employers from the presence of unemployed immigrants receiving tax financed income transfers the mutual benefit requires credible labor market disciplining through job offers to immigrants and willingness of immigrants to accept job offers acceptance of job offers results in displacement in employment of national workers by immigrants which can compromise the effectiveness of efficiency wages as a counter to anti immigrant voter sentiment in the welfare state

undocumented immigration and unemployment of u s youth and minority workers econometric evidence we use census based data on the state distribution of the undocumented alien population in analyzing the relationship between that population and unemployment among youth and minority workers in the united states regression results from our two equation models do not support commonly expressed fears that undocumented immigration has caused any substantial increases in joblessness among these presumably vulnerable groups although small amounts of displacement are indicated a sizeable reverse effect is evident undocumented immigrants tend to concentrate in states where labor markets for these marginal groups are most favorable excerpt

the welfare effects of illegal immigration abstract this paper extends the work of ethier on illegal immigration by examining the optimal level of enforcement for the labor importing country in a two country model and by considering the effects of allowing capital mobility we derive a formula for the optimal level of enforcement against firms that hire illegal workers and show that the presence of enforcement costs makes the policy less efficient than a wage tax with capital mobility foreign workers gain from an increase in enforcement in the home country because capital is driven out of the home country

community composition and the provision of local public goods abstract there is considerable evidence suggesting that the composition of the community that is the characteristics of the residents themselves plays a central role in determining levels of important public outputs such as education and public safety this paper explores the normative implications of this evidence we show that optimal community composition involves a trade off between the gains from homogeneity in demands among residents and the gains from heterogeneity in the production of those goods the analysis establishes a role for equalizing intergovernmental grants on efficiency grounds such grants can provide the needed incentives for sustaining heterogeneous communities

optimal policies with an informal sector abstract this paper characterizes optimal policies in the presence of tax evasion and undocumented workers in equilibrium domestic workers may work exclusively in the formal sector or also in the informal sector surprisingly in equilibrium wages are always equalized between domestic and undocumented workers even if they do not work in the same sectors of the economy this is driven by the interaction of firm level decisions with optimal government policy we also find that enforcement may not always be decreasing in its cost and that governments will optimally enforce labour market segmentation if enforcement costs are not too high

the role of policy in energy transitions lessons from the energy liberalisation era the aim of this paper is to discuss the period of energy privatisation and liberalisation which began in the 1980s within its wider historical context the key issues are what has been learned from this recent period and how significant is it in the light of an energy transition to low carbon energy system by 2050 energy liberalisation has led to positive and globally widespread but modest efficiency gains but a lack of clearly visible direct benefits to households in many countries it has significantly improved the governance of monopoly utilities via independent regulators the prospects for competition and innovation and the quality of policy instruments for environmental emissions control through the emergence of trading mechanisms we conclude that it is not liberalisation per se that will determine the movement towards a low carbon energy transition but the willingness of societies to bear the cost which will be significant no matter what the extent of liberalisation

economic effects of immigrants on native and foreign born workers complementarity substitutability and other channels of influence the authors use standard metropolitan statistical area smsa data constructed from 1980 census microdata files and other sources to estimate a structural model of native foreign born labor demand and labor supply which distinguishes the effects upon real wages of each type of labor and on the employment of natives the authors specify econometrically estimate and simulate the structural model which incorporates not only a production structure channel through which immigrants influence area real wages and employment but also demand and native labor supply channels it is noted that while these are not the only channels through which immigrants may affect native workers the model nonetheless constitutes a step in the direction of a general equilibrium approach in the production structure channel immigrants and natives are found to be substitutes in production immigration lowers foreign born wage rates and leads to lower wages for natives the negative effects of the production channel usually are ameliorated through the demand channel further immigrants add to local demand through their earnings and potentially through non labor income while also lowering unit costs and local prices which enhances real incomes and potentially net exports and thus the demands for local output and area labor the author discusses findings of interest from the simulation results based upon an analysis of all areas

do interest groups affect us immigration policy while anecdotal evidence suggests that interest groups play a key role in shaping immigration policy there is no systematic empirical analysis of this issue in this paper we construct an industry level dataset for the united states by combining information on the number of temporary work visas with data on lobbying activity associated with immigration we find robust evidence that both pro and anti immigration interest groups play a statistically significant and economically relevant role in shaping migration policy across sectors barriers to migration are lower in sectors in which business interest groups incur larger lobbying expenditures and higher in sectors where labor unions are more important

redistribution within and across the regions of a federation the authors reconsider the literature on redistribution within a federation with mobile agents they conclude that redistribution is a function best assigned to the national government local governments with diverse preferences for redistribution distort individual migration decisions the authors also examine the fiscal externality literature which has made an efficiency argument for interregional transfers they show that if local governments have the same preferences for redistribution the nash equilibrium is efficient if preferences are diverse the authors show that nationally imposed interregional transfers do not address the source of the inefficiency nevertheless interregional transfers are shown to be a part of decentralized behavior

on the macroeconomic and welfare effects of illegal immigration abstract this paper uses a dynamic general equilibrium model with labor market frictions to explore the economic consequences of illegal immigration in the baseline model native workers and illegal foreign workers compete for jobs in the same market but serve as imperfect substitutes in production the calibrated model generates a u shaped relationship between long run domestic consumption and the population share of illegal immigrants after taking into account both consumption and leisure i found that an increase in illegal immigration can generate significant welfare gains for the natives the baseline model is then extended to include heterogeneous workers in the domestic population

politically realistic objective functions and trade policy profs and tariffs abstract this paper demonstrates a mathematical correspondence between the deus ex machina tariff formation approach and political economy approach the correspondence implies that the tariff chosen by lobbying influenced policy makers will be equivalent to a tariff chosen by a deus ex machina government that gives too much weight to profits this result allows many political economy issues to be addressed in the simple framework of a deus ex machina government which faces a politically realistic objective function prof

trade aid and migrations some basic policy issues the link between trade policy and international migration is explored using data from the united states and europe we conclude that restrictive trade policies in industrialised countries have most likely added to migration pressures we then turn to the broader question of the effects of income growth in the sending countries on the propensity to migrate we argue that in relatively poor countries an increase in income will be associated with higher migration flows for middle income countries however income growth will lead to lower migrations in the medium run therefore the relationship between development levels as measured by gdp per capita and the propensity to migrate follows an inverse u pattern econometric analysis of aggregate migration flows from southern europe provides considerable support for such conjecture excerpt

bridging trade theory and labour econometrics the effects of international migration this paper surveys current theoretical and empirical research on international migration with a particular emphasis on the links between trade theory and labour empirics

assistance to the poor in a federal system abstract this paper explores the roles of different levels of government in assisting the poor using a model incorporating utility interdependence the paper first presents some theoretical results indicating how levels of poor relief vary with the extent of mobility of the poor under both centralized and decentralized systems of support it then provides a survey of the empirical work on migration of the poor along with a brief historical discussion of the experience under the english poor laws the concluding section turns to normative issues and contends that mobility of the poor is a basic source of inefficiency in wholly decentralized systems of support this inefficiency along with certain other equity considerations establishes a role for the central government in assistance to the poor

decentralized income redistribution and immigration abstract we analyze the welfare and other effects of immigration on a system of jurisdictions with a common labor market mobile capital and redistributive tax transfer policies comparative statics analysis of a model of nash non cooperative equilibria in tax transfer policies shows that the welfare effect of immigration depends on whether immigrants are net fiscal contributors or burdens any one jurisdiction s redistribution and immigration policies generate fiscal externalities for others in the system which a central government can internalize by appropriate taxes and subsidies

why do rich countries prefer free trade over free migration the role of the modern welfare state abstract according to traditional trade theory heckscher ohlin free trade and free migration are equivalent measures of economic integration leading both to an equalization of factor prices this prediction is in sharp opposition to the observed preference of rich countries for free trade over free migration we provide an explanation for this inconsistency the redistribution policies in the countries social welfare in countries with a relatively small number of low skilled native workers is higher with free trade than with free migration due to redistribution of income towards immigrating workers

mobility and redistribution the ability of individuals to move freely from one jurisdiction to another is generally seen as a constraint on the amount of redistribution that each jurisdiction within a system of governments can undertake in this paper we look at this proposition by developing a positive analysis of income redistribution by local governments in a federal system we ask how much redistribution occurs when only local governments can have tax transfer instruments individuals can move freely among jurisdictions and voters in each jurisdiction are fully aware of the migration effects of redistributive policies local redistribution is shown to induce sorting of the population with the poorest households located in the communities that provide the most redistribution while the threat of out migration affects the potential for redistribution our results suggest that significant local redistribution is nonetheless feasible numerical computations indicate that the proportion of residents who are renters is a major factor affecting the local choice of level of redistribution

trade in a tiebout economy the purpose of this paper is to explore both the positive and normative aspects of commodity trade in a tiebout economy by tiebout economy i mean an economy with a large number of small regions for example communities or states and no impediments to the mobility of individuals between these regions this type of economy has received widespread attention since the appearance of charles tiebout s classic 1956 article on local public goods in part because it bears a close relation to the standard competitive model this relation suggests that tiebout economies may serve as an

social protection and political competition this paper analyses how the level of social protection is determined when its choice depends on political competition first this is done under autarky then the analysis is extended to take account of the existence of an international capital market we show that social protection never increases under international competition and in several circumstances drastically decreases

tax policy in the presence of emigration recent policy and theoretical discussions of the effects of highly skilled migration from the underdeveloped countries the so called brain drain have focused on a proposal bhagwati 1972 to levy a supplementary income tax on those who migrate the proceeds of such a tax to be transmitted to the developing country of origin or to developing countries en bloc for developmental spending the welfare implications of such a tax were analyzed in an earlier paper of ours bhagwati and hamada 1974 in the context of a model of the country of emigration characterized by sticky wages and harrisstodaro 1971 type of unemployment in subsequent papers the tax has been analyzed also in the context of modified models still incorporating the unemployment phenomena by rodriguez 1975 and mcculloch yellen 1975 2 essentially these models analyze the impact of the income tax on emigrants incomes as arising primarily through the reduced differential

excessive deficits sense and nonsense in the treaty of maastricht maastricht s fiscal rules willem buiter giancarlo corsetti and nouriel roubini the maastricht treaty on economic and monetary union in the ec has specified limits on both government debt and fiscal deficits satisfying these criteria is necessary for getting into emu once inside violating these limits will also incur penalties the fiscal requirements especially the debt criterion are much tougher than is required to ensure public sector solvency trying to attain these targets will force the ec initially into substantial deflation and recession failure to correct for real growth inflation and the business cycle makes the nominal deficit a poor basis for any policy or target ambiguity about how fiscal targets will in fact be interpreted might provide a way out but cannot today be relied upon to do so supranational fiscal rules are sometimes claimed to be justified by externalities in national fiscal policies we find this justification wanting both in theory and empirically a better case might be built on the imposition of external commitments to offset domestic political distortions that systematically induce excessive deficits even so we conclude that the fiscal convergence criteria on balance are harmful and should be disregarded or applied very loosely to avoid the risk of serious fiscal overkill

sustaining fiscal policy through immigration this paper explores the fiscal implications of immigration to the us and argues that immigration policy should be viewed as a vital part of fiscal policy in particular a case is made that skill

externalities and nonlinear discounting indeterminacy abstract this paper studies a one sector model with externalities and nonlinear discounting loosely if the bellman equation for a standard model is written as v k max u v k then the bellman equation for our model is written as v k max u b v k for some concave function b our model assumes that period utility u is linear in consumption and leisure and the production function exhibits increasing social returns and nonincreasing private returns we establish the existence of a steady state under fairly general conditions and give a necessary and sufficient condition for local indeterminacy we show that regardless of the degrees of increasing returns and externalities there exists a discount function b such that indeterminacy arises we also show that in a certain sense as the degree of increasing returns converges to zero the variability of discounting the second derivative of b required to generate indeterminacy also converges to zero numerical examples are provided the main results are also extended to a one sector model with fixed labor supply

illegal immigration in an efficiency wage model abstract this paper studies illegal immigration using an efficiency wage dual labor market model the illegal immigrants are endogenously sorted completely or incompletely into secondary labor markets the effects of immigration on native workers are more complex than in standard models of factor mobility as illegals first enter the country natives may gain because the number of primary sector jobs rises with enough illegals in the country natives are hurt because the migrants increasingly take those primary sector jobs enforcing immigration laws by deporting migrants who work in primary sector jobs is pareto superior to other forms of enforcement

a theory of dual labor markets with application to industrial policy discrimination and keynesian unemployment this paper develops a model of dual labor markets based on employers need to motivate workers in order to elicit effort from their workers employers may find it optimal to pay more than the going wage this changes fundamentally the character of labor markets the model is applied to a wide range of labor market phenomena it provides a coherent framework for understanding the claims of industrial policy advocates it also can provide the basis for a theory of occupational segregation and discrimination that will not be eroded by market forces finally the model provides the basis for a theory of involuntary unemployment

factor movements and commodity trade as complements abstract several models are presented in which factor mobility leads to an increase in the volume of world trade the models share the common characteristic that the basis for trade is something other than differences in relative factor endowments these alternative bases for trade include returns to scale imperfect competition production and factor taxes and differences in production technology taken together the models suggest a more general idea the widely held notion that trade in goods and factors are substitutes is in fact a rather special result which is a general characteristic only of factor proportions models

searching for the effect of immigration on the labor market we compare two approaches to analyzing the effects of immigration on the labor market and find that the estimated effect of immigration on u s native labor outcomes depends critically on the empirical experiment used area analyses contrast the level or change in immigration by area with the level or change in the outcomes of non immigrant workers factor proportions analyses treat immigrants as a source of increased national supply of workers of the relevant skill the different effects of immigration on native outcomes in the area and factor proportions methodologies appear to result from the diluting effect of native migration flows across regions and failure to take adequate account of other regional labor market conditions in area comparisons excerpt

national origin and immigrant welfare recipiency this paper explores national origin differences in the welfare recipiency of immigrants to the united states we develop an economic model of immigration which generates implications about how welfare utilization should vary according to characteristics of the country of origin the empirical analysis reveals that a few source country characteristics explain over two thirds of the variance of welfare recipiency rates across national origin groups and changes in the average source country characteristics of the foreign born population between 1970 and 1980 can account for most of the rise in immigrant welfare use that occurred over the decade

on the choice between capital and labour mobility trade theorists since the pioneering work of kemp 1966 have considered the question of national advantage from international factor mobility by considering only one factor to be so mobile kemp analyzed elegantly the question of optimal policies in 2 x 2 x 2 model and showed that since monopoly power could exist in both the goods and factor markets in consequence of international capital mobility the optimal policy intervention would generally involve two policy instruments tariffs cum subsidies on goods and duties cum subsidies on international capital flows jones 1967 subsequently extended kemp s argument to the secondbest context by examining the optimal level of one of these instruments when the other was arbitrarily set at zero elsewhere in this issue brecher 1983 shows in an elegant and original contribution that the jones policy problem is in fact a third best rather than a second best problem as generally believed and that if only one of the tariff and capital mobility taxes cumsubsidies can be used it is generally possible to improve welfare further by admitting an altogether different domestic policy instrument namely a production or consumption tax cum subsidy as the case may be the research of bhagwati was supported by the german marshall fund grant no l 34015 the problem analyzed in the paper was posed in bhagwati 1979 and an early ingenious and neglected analysis in ramaswami 1968 was noted by bhagwati we have profited greatly from these contributions also from reading webb 1970 ramaswami 1970 and a recent paper of calvo and wellisz 1983 on this problem this result is in consonance with the results of bhagwati ramaswami and srinivasan 1969 for the case without international capital mobility but the consonance is intuitive only after the result was established for the case with international capital mobility

controlling migration in an open labor market a direct immigration policy is no longer feasiblefor a single region in a common labor market within apolitical economy approach this paper focuses on the question ofwhether migration can be controlled through the composition ofgovernment expenditures taking into account both capital and laborincome it turns out that the median voter s income is u shaped in thenumber of immigrants therefore the government can eitherprovide less of the goods preferred by foreigners in order to minimizeimmigration or carry out an active immigration policy byshifting its expenditures towards those publicly provided goods thepaper identifies the factors that determine the government schoice between the two strategies

on the size of u s government political economy in the neoclassical growth model we study a dynamic version of meltzer and richard s median voter model of the size of government taxes are proportional to total income and they are redistributed as equal lump sum transfers voting takes place periodically over time and each consumer votes for the tax rate that maximizes his equilibrium utility we calibrate the model to u s data key elements in the calibration are the income and wealth distribution and the parameters governing the leisure and consumption choices the total size of transfers predicted by our political economy model is quite close to the size of transfers in the data

on the political economy of immigration the authors study how immigration policies that impose capital and skill requirements would be determined under majority voting when native agents differ in their wealth holdings and vote to maximize their income the results of the model calculations indicate that the native population will be polarized between those who would like an immigration policy to maximize the domestic capital labor ratio and those who would like an immigration policy that would minimize it

international trade and labor migration a theory of the relationship between international trade and labor mobility is developed that takes into account five characteristics of such migration including its temporary nature differences between migrant and native labor the acceptance of unpredictable conditions of employment by migrant labor the ready availability of further labor resources and international capital mobility particular attention is paid to the role of international labor migration in helping to insulate native populations from the rigors of industrial fluctuations and in helping to preserve import competing industries that would have succumbed without the availability of cheap imported labor

the dynamics of u s internal migration in this paper we have theoretically derived a net migration equation and estimated it using time series data for 51 u s regions over the period 1971 1988 the results indicate that the dynamic response of net migration is stable and is significantly related to stock equilibrium changes induced by amenity differentials relative employment opportunities relative real wages and industry composition excerpt

the theory of international factor flows the basic model abstract the basic model used to discuss the simultaneous international flow of labor and capital is a one commodity model in which a common technology is shared between countries the ramaswami result wherein an optimal restriction of labor inflows is superior to an optimal restriction on capital outflows for a capital abundant country is extended to reveal that optimality requires inflows of both factors box diagrams and iso welfare contours are used to show how optimal policy rankings are reversed if foreign labor must be paid higher home wages

the economics of immigration this literature review concerns the impact of immigration on the economy of the host country focusing on the experience of the united states the emphasis is on the period from the 1970s to the 1990s the author shows that research earlier in this period generally concluded that the economic effects of immigration were positive but that more recent research on later migrations have generally concluded that immigration may be having an adverse effect on the earnings of native unskilled workers and be placing an increased burden on welfare programs the importance of such economic analysis for the formulation of appropriate migration policies is stressed

attachment to home and efficient purchases of population in a fiscal externality economy abstract this paper examines the efficiency properties of an economy characterized by strategically competing regions and individuals with varying degrees of attachment to home in an otherwise standard fiscal externality setting regional authorities may make interregional transfers in purchasing preferred populations however there is a range of distributions of resources over which neither region makes transfers nevertheless all equilibrium allocations resulting from the nash behavior of regional authorities including those that involve no transfers are efficient therefore in contrast to the standard conclusions of the fiscal externality literature there is no efficiency role for a central authority

immigration and income redistribution a political economy analysis this paper examines the effect of immigration on the extent of income redistribution via majority voting on the income tax the tax outcome depends on the size of the native majority and the initial amount of redistribution in the economy which in turn determines the skill composition of immigrants as a main result we derive conditions for multiple tax equilibria if the native majority of either skilled or unskilled is not too strong and immigrants are allowed to vote both a high tax and a low tax outcome is possible in a referendum natives will then vote against immigrant voting at best natives are indifferent towards immigrant voting

factor rewards and the international migration of unskilled labor a model with capital mobility abstract conventional economic wisdom holds that the migration of unskilled labor from less developed countries to neighboring developed countries should be expected to narrow the wage gap between those countries and thereby reduce the incentive for further migration if capital is mobile internationally this reasoning may be inappropriate instead emigration of unskilled labor out of the less developed country provides an incentive for capital to leave the country too as a consequence wage rates move in the same direction in each country and the gap between wage rates across countries even may increase

political economy sectoral shocks and border enforcement in this paper we examine the correlation between sectoral shocks and border enforcement in the united states enforcement of national borders is the main policy instrument the u s government uses to combat illegal immigration the motivation for the exercise is to see whether border enforcement falls following positive shocks to sectors that are intensive in the use of undocumented labor as would be consistent with political economy models of how enforcement policy against illegal immigration is determined the main finding is that border enforcement is negatively correlated with lagged relative price changes in the apparel fruits and vegetables and slaughtered livestock industries and with housing starts in the western united states this suggests that authorities relax border enforcement when the demand for undocumented workers is high

efficiency wage models of unemployment keynesian economists hold it to be self evident that business cycles are characterized by involuntary unemployment but construction of a model of the cycle with involuntary unemployment faces the obvious difficulty of explaining why the labor market does not clear involuntarily unemployed people by definition want to work at less than the going wage rate why don t firms cut wages thereby increasing profits

the role of portuguese electricity generation regimes and industrial production abstract this paper examines how renewables special regime simultaneously interact with conventional sources ordinary regime within the portuguese electricity generation system there is also an appraisal of the relationship between these two regimes and economic activity using the industrial production index first difference var modelling was applied for monthly data for the time span of 2007 m1 to 2012 m10 the appropriateness of the var is proved the relationship between variables develops within a structure of endogeneity i e they generate feedback and may be both explained and explaining variables simultaneously the outcomes show a strong complementarity between the ordinary and special regimes economic activity causes electricity consumption but only the special regime causes economic activity moreover the non renewable component of the special regime does not cause a need for backup from either the ordinary regime or imports contributing to a reduction in energy dependency

efficiency wages employment versus welfare this paper analyzes the effects of government policies in an efficiency wage model in such a model wages exceed market clearing rates firms may pay high wages for many reasons levine gives thirteen motivations for efficiency wages 12 in the model used here high wages prevent shirking by workers the model is similar to those of shapiro and stiglitz sparks fairris and alston and others 15 17 7 efficiency wage models are often viewed as providing the microeconomic foundations of involuntary unemployment and keynesian economics 1 2 unemployment is also emphasized in many discussions of government policies 3 4 11 a major example is that of johnson and layard 9 they find that a per capita employment subsidy financed by an ad valorem wage rate tax would reduce unemployment they conclude that this policy would benefit a country because of the employment effect 2 yet this paper shows that the employment effect is misleading here a policy that causes employment to rise fall also must cause income net of effort to fall rise so total welfare falls rises the policy implications discussed by johnson and layard and others are therefore reversed

us immigration policies and dynamics of cross border workforce in agriculture given the contentious debate on immigration this study develops a dynamic model to analyse the effects of stricter border and domestic enforcement and streamlining the guest worker programme on cross border migration from mexico employment and production in us labour intensive and mexican agriculture and the us and mexican wage rates the model incorporates labour leisure decisions of mexican workers and labour market dynamics and linkages the findings show stricter border and domestic controls exacerbate the labour shortage problems and reduce the us agricultural production streamlining the guest worker programme provides a steady supply of farm workers and has negligible impact on the us wage

implications of liberalization policies on government support to r d lessons from electricity markets since the early 1980s electricity industry reforms have been initiated in more than half of the countries in the world among the primary targets of these reform schemes there has been an increase in efficiency of the sector and it is implicitly assumed that government support to energy technology r d will progress in line with the reform process as the former is required to sustain improved efficiency in the middle and long run the paper reviews the relation between reform process in electricity markets and government support to energy r d using panel data from 27 countries covering the period from 1974 to 2008 this study aims at finding out to what extent the expected correlation between reform process and government support to energy r d has in practice been materialized so far the findings suggest that contrary to expectations the progress toward electricity market reform is associated with reduced government support to a variety of energy r d activities which threatens sustainable efficiency improvements in the power industry

trade capital mobility and tax competition this paper examines a system of governments national state or local that finance public expenditures with taxes on mobile capital e g a property tax unlike previous research on tax competition explicit consideration is given to the general equilibrium determination of the prices at which goods are traded between regions the analysis identifies inefficiencies in government behavior that are not apparent in models in which the terms of trade are exogenously given capital taxation is shown to create an inefficient distribution of public good outputs across regions accompanied by an inefficient pattern of trade a model is presented in which the chosen levels of public good outputs differ across regions containing identical residents and production possibilities there is a wasteful diversity of public good supplies

factors influencing farmers adoption of energy based water pumps and impacts on crop productivity and household income in pakistan abstract the current study is based on comprehensive cross sectional data set collected through field survey from all the four major provinces of pakistan i e punjab sindh kpk and balochitan in total 950 farmers were interviewed this paper attempts to examine the factors that influence farmers choice of water pumps e g electric diesel solar photovoltaic pv or biogas and to assess the impact of these water pumps on crop productivity household income and poverty the paper uses the multivariate probit model and propensity score matching approach in order to achieve these objectives the empirical results indicate that educated younger and wealthier farmers are more likely to adopt alternate energy based water pumps for irrigation access to credit facilities and frequent hours of load shedding are key factors influencing a farmer s decision to adopt alternative energy based water pumps rather than relying on electricity alternative energy sources have positive and significant impacts on the productivity of wheat rice and maize crops and on household income the use of alternative energy sources for water pumping has resulted in the reduction of poverty in the range of 11 20 the study has important policy implications the current energy crisis in pakistan has adversely affected farming operations and in turn crop yield and the use of water pumps for irrigation based on alternative energy sources has increased crop productivity access to these renewable energy technologies for water pumping should be encouraged through subsidies and easy availability of credit facilities as the majority of farmers in pakistan are resource poor with small landholdings

on impatience economic growth and the environmental kuznets curve a dynamic analysis of resource management the paper presents a dynamic analysis of natural resource management and investigates some key factors that affect optimal management and resource conservation using a recursive specification of time preferences we show how endogenous discounting and impatience can affect the motivation for both capital investments and environmental preservation we examine the relationships between economic growth and environmental quality endogenous discounting provides new insights in the economic dynamics underlying the environmental kuznets curve by treating growth as endogenous we examine how externalities and economic growth interact with each other we investigate how economic development can contribute to an increased demand for environmental preservation as an important new result we also show how poverty can contribute to environmental degradation

foreign aid and illegal immigration abstract we develop a two country model of illegal immigration we analyse the effect of foreign aid on illegal immigration and consider both exogenous and endogenous income repatriation in the former an increase in aid increases illegal immigration if the total amount of aid is small a transfer of resources from border control to aid increases illegal immigration when the total amount of aid is small under endogenous income repatriation aid has no effect on illegal immigration when the preferences of the immigrants and their family members are the same if the preferences are different aid may increase illegal immigration

an efficiency wage model with explicit monitoring abstract this paper develops an efficiency wage model of involuntary unemployment in a small open economy which uses two factors to produce three goods one of which is non traded monitoring aimed at reducing shirking by workers in all industries the analysis shows how a tariff on imports may lower employment but paradoxically raise social welfare at the same time as the paper also demonstrates the optimal policy combination includes not only taxes on capital and monitoring as well as a subsidy on employment but also despite the small country assumption a tax on consumption

effects of renewables on the stylized facts of electricity prices abstract many countries around the world have increased their renewable installed capacity due to a greater awareness of climate concerns under this new framework with renewables being among the main generation sources the literature warns of a dramatic change in price behaviour some of the most commonly claimed effects of having a significant proportion of renewable generating sources in the total electricity production mix include i a systematic decrease in overall wholesale market prices ii a higher occurrence of price jumps and iii a significant increase in price volatility the goal of the present study is to test whether these changes in price behaviour have actually come about to do so we focus on the spanish day ahead electricity market as a paradigmatic example in line with the literature it is found a statistically negative relationship between the renewable generation share and the day ahead market marginal prices as well we have obtained statistical confirmation of the fact that renewables generation share volatility is transferred to price volatility though similarly to other generation technologies finally in contrast to the general belief that the introduction of renewable generation would give rise to extreme positive prices according to our results increases in renewables generation share reduce the probability of upward jumps in prices the results obtained are of interest for portfolio managers practitioners and regulators

electricity costs in irrigated agriculture a case study for an irrigation scheme in spain abstract electricity prices have risen sharply in spain in recent years to the point where they are now among the highest in the eu the scant competition between power utilities changes in the law and the tariff deficit accumulated debt in favour mainly of the electricity firms have driven up the cost of electricity affecting numerous other industries such as irrigated agriculture a sector that has significantly increased its electricity consumption as a result of modernization processes over the past twenty five years we examine these issues through a case study of an irrigation scheme in spain that provides irrigation water and infrastructure to 58 farming communities in north eastern spain and is highly representative of the ebro valley based on the results of direct estimations and simulations of different tariffs we propose the lowering of capacity based tariffs to reduce sector problems and cut energy costs especially for farmers we also raise the possibility of increasing self consumption a complementary measure for many farmers and for medium size firms

citizen candidate mobility and endogenous local policy in this paper we analyze the influence of personal mobility on the citizens willingness to run for a political office in their municipality and on the resulting local policy outcome our model portrays heterogeneous policy preferences that are coupled with different exogenous degrees of interjurisdictional mobility we show that an increase in mobility can be liable to shift the policy outcome towards the preferred policy of the less mobile citizens we thus identify an endogenous policy response to personal mobility diametrically opposed to the tax competition effect that has hitherto dominated the discussion of the political consequences of personal mobility

undocumented mexico u s migration and the returns to households in rural mexico this paper presents estimates of net income gains to a sample of households in rural mexico from sending migrants illegally to the united states correcting for sample selectivity bias and it examines the role of expected income gains in driving illegal mexico u s migration there is no evidence that people who migrate illegally to the united states are above average contributors to household income either as workers in mexico or as mexico u s migrants however other things being equal villagers who are in the best position to contribute to household income as workers in mexico are positively selected not to migrate to the united states

a political economic analysis of labor migration and income redistribution we present a two country political economic model of income redistribution with internationally mobile labor migration can be exogenous and or endogenous i e determined by labor income differentials political influence is determined by the size and homogeneity of the groups where the latter can be affected by immigration we show that immigration can increase the transfers to and the income of the mobile group we also investigate the possibility of migration regulation tax transfer policy competition and coordination and finally coordination of regulation policies it is shown that the selection of any of those regimes will depend on the particular distribution of political influence among the relevant social groups in the two countries

efficiency wages in a ricardian model of international trade abstract this paper examines the implications of efficiency wages for international trade in a simple extension of the ricardian model in which labour performs two different tasks in production and where workers are imperfectly monitored in the performance of one of the tasks as a result of the factor market distortion the one factor economy may behave like a heckscher ohlin model an important result is that transfers of income have efficiency reducing effects and hence the standard aggregate analysis of trade policy may be inappropriate
