explaining the deteriorating entry earnings of canada s immigrant cohorts 1966 2000 abstract using the 1981 1986 1991 1996 and 2001 canadian censuses we explore causes of the deterioration in entry earnings of successive cohorts of immigrant men and women roughly one third of the deterioration is explained by compositional shifts in language ability and region of birth we find no evidence of a decline in the returns to foreign education for either immigrant men or immigrant women but a definite deterioration in the returns to foreign labour market experience most strongly among men from non traditional source countries we can explain roughly two thirds of the male and one half of the female deterioration without any reference to entry labour market conditions when we also account for entry conditions our results suggest canada s immigrants of the late 1990s would otherwise have enjoyed entry earnings equal to or higher than their counterparts of the 1960s

the fiscal impact of immigration in france a generational accounting approach the objective of this study is to use both static and dynamic frameworks to compare the benefits that immigrants draw from the public system with their contributions through the taxes that they pay the main conclusion of this paper is that the impact of immigration on welfare systems is weak thus if we compare on a given date immigrants global contribution to the public administration budget with the volume of transfers they receive immigrants appear to be relatively favoured by the redistribution system at the same time even if immigrants seem to pay less taxes and receive more transfers than natives the difference in distribution between the two populations with a higher concentration of immigrants in the active age groups and a sparser concentration among the net beneficiaries of the social transfer system leads to a slightly positive long term impact of immigration on public finances however the impact of immigration remains very slight compared with the global effort that would have to be undertaken to reduce budgetary imbalances

the wage premium to a university education in canada 1971 1991 using micro data from the canadian survey of consumer finances 1971 91 we investigate the return to a university education our conclusions are that while there appears to have been some decline in the return to a university degree during the 1970s in canada similar to the united states the return did not rebound much during the 1980s except among the youngest experience age group there is however considerable noise in the ratios from year to year so that one is likely to draw misleading inferences if only a few years of data are used

gathering imperfect information before signing a contract i study information gathering for rent seeking purposes in contracting in my model an agent learns his payoff type only after accepting a contract but can at costs acquire imperfect information while deliberating whether to accept i show that the principal deters the acquisition if and only if the costs are high the result stands in contrast to a finding by cremer and khalil 1992 who demonstrate that the acquisition of perfect information will always be deterred a key insight is that the case of imperfect information is an instance of a sequential screening problem

a search equilibrium approach to the effects of immigration on labor market outcomes we analyze the impact of the skill biased immigration inux that took place during the years 2000 2009 in the united states within a search and matching model that allows for skill heterogeneity dierential search cost between immigrants and natives capital skill complementarity and possibly endogenous skill acquisition within such a framework we nd that although the skill biased immigration raised the overall net income to natives it may have had distributional eects specically unskilled native workers gained in terms of both employment and wages skilled native workers on the other hand gained in terms of employment but may have lost in terms of wages nevertheless in one extension of the model where skilled workers and immigrants are imperfect substitutes we nd that even the skilled wage may have risen

on the simple economics of advertising marketing and product design we propose a framework for analyzing transformations of demand such transformations frequently stem from changes in the dispersion of consumers valuations which lead to rotations of the demand curve in many settings profits are a u shaped function of dispersion high dispersion is complemented by niche production and low dispersion is complemented by mass market supply we investigate numerous applications including product design advertising marketing and sales advice and the construction of quality differentiated product lines we also suggest a new taxonomy of advertising distinguishing between hype which shifts demand and real information which rotates demand

multi dimensional screening a user s guide abstract multi dimensional screening models have many potential applications but economists have so far been hindered by the considerable technical difficulties involved in their resolution this paper studies the simplest formulation of the general screening model and we provide a complete solution to this case we then show how this model can be applied to multi product nonlinear pricing and to multi product monopoly regulation finally we discuss how the model has been applied to other economic situations of interest including auction design and optimal taxation

international migration and trade agreements the new role of ptas this paper provides an empirical analysis of the relationship between preferential trade agreements ptas and bilateral migration flows building on the empirical literature on the determinants of migration flows i estimate a modified gravity model to assess the role of ptas and their content on bilateral migration flows using a sample of 29 oecd destination countries over the period 1998 2008 i show a strong positive effect of ptas on bilateral migration flows i find that the content of ptas also matters when visa and asylum and labour market related provisions are included in ptas this further stimulates bilateral migration flows different estimation strategies including instrumental variables are employed to address the potential endogeneity bias problems related to ptas and their content

facilitating consumer learning in insurance markets what are the welfare effects we model a monopoly insurance market where consumers can learn their accident risks at a cost c we then ask what are the welfare effects of a policy that reduces c if c is sufficiently small c c marginally reducing c hurts the insurer and weakly benefits the consumer finally a reduction in c that is successful meaning that the consumer gathers information after the reduction but not before it can hurt both parties this article is protected by copyright all rights reserved

immigration social security and broader fiscal impacts population aging and rising health costs will cause dramatic increases in federal expenditures some decades from now lee et al 1999 rising immigration to the united states may help avert this future crisis by slowing population aging and helping to pay for social security and public health care but many immigrants have low education and high fertility so their net fiscal impact may be costly rather than beneficial this paper revisits our earlier analysis of the fiscal impact of immigration lee and miller 1997 henceforth lm97 in light of higher projected rates of productivity growth an unexpected increase in the effective federal income tax rate in recent years and some revisions of the demographic projections we will emphasize implications for social security and address points raised by the recent literature holger bonin et al 1998 george borjas 1999 alan auerbach and philip oreopolis 2000 kjetil storesletten 2000

a time series analysis of representative agent models of consumption andleisure choice under uncertainty this paper investigates empirically a model of aggregate consumption and leisure decisions in which utility from goods and leisure is nontime separable the nonseparability of preferences accommodates intertemporal substitution or complementarity of leisure and thereby affects the comovements in aggregate compensation and hours worked these cross relations are examined empirically using postwar monthly u s data on quantities real wages and the real return on the one month treasury bill the estimated values of the parameters governing preferences differ significantly from the values assumed in several studies of real business models several possible explanations of these discrepancies are discussed

optimal auctions with information acquisition this paper studies optimal auction design in a private value setting with endogenous information acquisition first we develop a general framework for modeling information acquisition when a seller wants to sell an object to one of several potential buyers who can each gather information about their valuations prior to participation we then show that under certain conditions standard auctions with a reserve price remain optimal but the optimal reserve price lies between the mean valuation and the standard reserve price in myerson 1981 we provide sucient conditions under which the value of information to the seller is positive and also characterize the necessary and sucient conditions under which equilibrium information acquisition in private value auctions is socially excessive the key to the analysis is the insight that buyer incentives to acquire information become stronger as the reserve price moves toward the mean valuation

an empirical model of labor supply in a life cycle setting this paper formulates and estimates a structural intertemporal model of labor supply using theoretical characterizations derived from an economic model of lifetime behavior a two step empirical analysis yields estimates of intertemporal and uncompensated substitution effects which provide the information needed to predict the response of hours of work to life cycle wage growth and shifts in the lifetime wage path

on the links between stock and commodity markets volatility this paper investigates the links between price returns for 25 commodities and stocks over the period from january 2001 to november 2011 by paying a particular attention to energy raw materials relying on the dynamic conditional correlation dcc garch methodology we show that the correlations between commodity and stock markets evolve through time and are highly volatile particularly since the 2007 2008 financial crisis the latter has played a key role emphasizing the links between commodity and stock markets and underlining the financialization of commodity markets at the idiosyncratic level a speculation phenomenon is highlighted for oil coffee and cocoa while the safe haven role of gold is evidenced

optimal procurement contracts with pre project planning the paper studies procurement contracts with pre project investigations in the presence of adverse selection and moral hazard to model the procurer s problem we extend a standard sequential screening model to endogenous information acquisition with moral hazard the optimal contract displays system atic distortions in information acquisition due to a rent effect adverse selection induces too much infor mation acquisition to prevent cost overruns and too little information acquisition to prevent false project cancellations moral hazard mitigates the distortions related to cost overruns yet exacerbates those related to false negatives the optimal mechanism is a menu of option contracts that achieves the dual goal of providing incentives for information acquisition and truthful information revelation

revenue decentralization and inflation a re evaluation abstract a problematic feature of the existing empirical literature on the relationship between revenue decentralization rd and inflation is the use of inaccurate measures for rd using a newly constructed measure for rd that accounts for over time changes in sub national tax autonomy this paper finds that rd leads to lower inflation

revenue decentralization and income distribution abstract due to varying local revenue collection capacities and interest group activities revenue decentralization rd may lead to increased inequality this paper provides empirical evidence however that if coupled with good governance rd could improve income distribution

immigration quotas and skill upgrading a reason why immigration policy is such a contended issue is that often immigrants end up obtaining the right to vote and hence may affect future policies this paper offers a dynamic general equilibrium model of immigration policy in each period a heterogeneously skilled population chooses an immigration policy by majority vote voters anticipate that immigration affects the skill premium and the skill composition of the electorate the main insight is the existence of a trade off between skill complementary immigration and the resulting shift in political power i argue that a reasonably parameterized version of the model is consistent with the main features of us immigration

multidimensional incentive compatibility and mechanism design abstract incentive compatibility conditions are characterized in general for problems in which several goods are to be allocated and agents types are multidimensional two questions of monopoly pricing under multidimensional uncertainty are then analyzed first we find the optimal nonlinear pricing scheme when the monopolist knows only the distribution of an arbitrarily parameterized family of demand curves and second we solve for the optimal bundling policy for a multiproduct monopolist

further evidence on revenue decentralization and inflation abstract results from a panel regression study of 19 oecd member countries suggest that when the measure of revenue decentralization is limited to the revenues over which sub national governments have full autonomy its impact on inflation is not statistically significant

contracts with endogenous information abstract i study covert information acquisition and reporting in a principal agent problem allowing for general technologies of information acquisition when posteriors satisfy two dimensional versions of the standard first order stochastic dominance and concavity convexity of the distribution function conditions a first order approach is justified under the same conditions informativeness and riskiness of reports are equivalent high powered contracts that make the agent s informational rents more risky are used to increase incentives for information acquisition insensitive contracts are used to reduce incentives for information gathering the value of information to the agent is always positive the value of information to the principal is ambiguous

cross country variation in the impact of international migration canada mexico and the united states using data drawn from the canadian mexican and u s censuses we find a numerically comparable and statistically significant inverse relation between immigrant induced shifts in labor supply and wages in each of the three countries a 10 labor supply shift is associated with a 3 4 opposite signed change in wages despite the similarity in the wage response theimpactofmigrationonthewagestructuredifferssignificantlyacrosscountries international migration narrowed wage inequality in canada increased it in the united states and reduced the relative wage of workers at the bottom of the skill distribution in mexico jel j31 j61

fiscal decentralization central bank independence and inflation abstract we develop earlier cross sectional studies of inflation rates by adding the degree of tax centralization as another explanatory variable this makes central bank independence perform appreciably better as an explanatory variable also we find that centralized countries have higher inflation

finite sample bias in iv estimation of intertemporal labor supply models is the intertemporal substitution elasticity really small the empirical literature on intertemporal labor supply behavior documents that the intertemporal elasticity of substitution of labor supply is very low with a plausible range of zero to 0 2 drawing upon the literature on the distribution of instrumental variables iv estimators this paper demonstrates that this conventional wisdom is erroneous because it does not take into account the severe finite sample bias in these estimates that arise from weak instruments this paper adopts several approaches to adjust for the problems induced by these weak instruments the empirical results show that when uncorrected for finite sample bias the two stage least squares 2sls estimate of the elasticity is essentially zero as in most of the previous studies with its valid confidence interval being open ended however when corrected for finite sample bias the estimate becomes approximately 0 5 with a much tighter confidence interval

immigration and the diffusion of technology the huguenot diaspora in prussia abstract this paper analyzes long term effects of skilled worker immigration on productivity for the huguenot migration to prussia in 1685 religiously persecuted french huguenots settled in brandenburg prussia and compensated for population losses due to plagues during the thirty years war we combine huguenot immigration lists from 1700 with prussian firm level data on the value of inputs and outputs in 1802 in a unique database to analyze the effects of skilled immigration to places with underused economic potential exploiting this settlement pattern in an instrumental variable approach we find substantial long term effects of huguenot settlement on the productivity of textile manufactories jel j24 j61 l67 n33 n63 o33 o47

the changing labor market position of canadian immigrants this paper uses pooled 1971 1981 and 1986 canadian census data to evaluate the extent to which 1 the earnings of canadian immigrants at the time of immigration fall short of the earnings of comparable canadian born individuals and 2 immigrants earnings grow more rapidly over time than those of the canadian born variations in the labour market assimilation of immigrants according to their gender and country of origin are also analysed the results suggest that recent immigrant cohorts have had more difficulty being assimilated into the canadian labour market than earlier ones an apparent consequence of recent changes in canadian immigration policy labour market discrimination against visible minorities and the prolonged recession of the early 1980s summary in fre excerpt

an introduction to the economics of immigration in oecd countries the share of the foreign born in oecd countries is increasing and this article summarizes economics research on the effects of immigration in those nations four broad topics are addressed labor market issues fiscal questions the political economy of immigration and productivity international trade extreme concerns about deleterious labour market and fiscal impacts following from new immigrants are not found to be warranted however it is also clear that government policies and practices regarding the selection and integration of new migrants affect labour market fiscal and social cultural outcomes policies that are well informed well crafted and well executed beneficially improve population welfare

endogenous information and stochastic contracts abstract a growing literature analyzes revenue maximizing contracts for situations in which agents can acquire private information before they decide whether to join the contract it is conjectured that the results also apply to the more natural scenario where information can be acquired either before or after signing this paper shows that in fact the latter scenario is more favorable for the principal using stochastic contracts she can induce information acquisition with some probability and yet appropriate the generated surplus

canadian economics research on immigration through the lens of theories of justice we assess the current state of knowledge in the economics of immigration and consider how economic theories of knowledge can be used to further the goal of developing a just immigration policy in the process we highlight the contributions of economists working in canada and canadian economists internationally in furthering our understanding of this important research area we identify research gaps such as the need for more research on the underlying causes of the poor returns to foreign work experience for immigrants from non traditional source countries and the effect of immigrants on stimulating innovation more research is also needed on the implications of temporary foreign worker tfw programs and the growing importance of employers in immigrant selection systems la recherche canadienne en economie de l immigration a travers la lentille des theories de la justice on jauge l etat present des connaissances en economie de l immigration et on examine comment les theories economiques de la connaissance peuvent etre utiles dans la poursuite d un objectif qui serait de mettre en place une politique d immigration juste dans ce processus on souligne les contributions des economistes travaillant au canada a notre comprehension de ce chantier de recherche on identifie certaines zones d ombre comme la recherche pour comprendre les causes sous jacentes aux pauvres rendements de l experience de travail des immigrants en provenance des pays qui ne sont pas des sources d immigration traditionnelles et celle pour comprendre les effets des immigrants sur la stimulation de l innovation il faudra aussi davantage de recherches sur les implications des programmes pour attirer et accueillir les travailleurs etrangers temporairement et sur l importance croissante des employeurs dans les systemes de selection d immigrants

should germany have built a new wall macroeconomic lessons from the 2015 18 refugee wave abstract in 2015 2016 germany experienced a wave of predominantly low skilled refugee immigration we evaluate its macroeconomic and distributional effects using a quantitative overlapping generations model calibrated using german micro data to replicate education and productivity differentials between foreign born and native workers workers are modelled as imperfect substitutes in aggregate production leading to endogenous wage differentials we simulate the dynamic effects of this refugee wave with specific focus on the welfare impact on low skilled natives our results indicate that the small losses this group suffers can be compensated by welfare gains of other parts of the native population

productivity differences and the dynamic effects of labor movements barriers to labor mobility across countries coexist with substantial differences in living standards largely attributable to productivity differences a growth model with endogenous labor movements is used to assess the effects on output capital accumulation and welfare of removing barriers to labor mobility the model is parameterized so that it is consistent with evidence on historical labor movements and is applied to two cases the enlargement of the european union and the hypothetical creation of a common labor market in the north america the main finding is that there are large resulting gains in terms of output and welfare

temporary emigration and welfare the case of low skilled labor this article studies the implications of temporary emigration for the welfare of a source country the framework is one of general equilibrium where the economy s stocks of both capital and labor are endogenously determined by the saving and migration decisions of optimizing agents simulations of the model suggest that for realistic values of the parameters welfare of nonmigrants of the source country is maximized when the migrants are employed abroad for a period in the range of roughly 8 12 years the ideal duration is found to be an increasing function of the international wage differential migration costs and the degree to which the rights of migrants are protected in the host country

the performance of immigrants in the canadian labor market in this article we examine the economic assimilation of immigrants to canada we provide new evidence on immigrants who arrived in the 1970s and document an increase in the dispersion of labor market outcomes across immigrants of different vintages over time our results confirm u s evidence of permanent differences across immigrant cohorts what distinguishes the canadian experience is small or negative rates of assimilation for most cohorts over the sample period finally we test the overidentification of the assimilation process specified in previous studies and fail to reject the usual cohort fixed effect specification

gathering information before signing a contract after being offered a contract an agent has the possibility to observe the state of nature this enables him to refuse the contract in unfavorable states but burdens him with an observation cost the authors show that the principal offers a contract in which the agent has no incentive to observe the state of nature and they explore its terms later they show that the principal finds it profitable to organize competition between several agents even though he has monopoly power and can push a single agent down to his reservation utility copyright 1992 by american economic association

pegging emerging currencies in the face of dollar swings the aim of this article is to study ruptures of exchange rate pegs by focusing on the fluctuations of the anchor currency we test for the hypothesis that currencies linked to the usd are more likely to loosen their peg when the usd is appreciating while sticking to it otherwise to this end we estimate smooth transition regression models for a sample of 28 emerging currencies over the 1994 2011 period our findings show that while the real effective exchange rates of most of these countries tend to co move with that of the usd in times of depreciation this relationship is frequently reversed when the us currency appreciates over a certain threshold

fiscal decentralization central bank independence and inflation a panel investigation we reinvestigate the relationship between revenue decentralization rd central bank independence cbi and inflation by modifying the paper by eco 72 2001 95 we show that in contrast to the earlier findings rd has a negative impact on inflation if accompanied by both cbi and local accountability in low inflation countries however rd has a negative impact on inflation even without these additional factors though cbi accentuates this effect

exchange rate fluctuations and immigrants labour market outcomes new evidence from australian household panel data abstract in this paper we exploit plausibly exogenous changes in exchange rates across home countries over time and panel data to identify the causal impact of exchange rate fluctuations on australian immigrants labour market outcomes we present new and robust evidence that unlike immigrants in the us those in australia as a whole do not reduce their yearly labour market outcomes when the local currency appreciates while female immigrants don t adjust their labour activities male immigrants reduce their weekly labour supply and hence earn less when the australian dollar appreciates this work also highlights the importance of controlling for individual heterogeneity as well as gender when modelling the labour market behaviour of immigrants

skills and the pattern of migration the role of qualitative and quantitative restrictions on international labor mobility this paper develops a two country model of international migration in an attempt to study the role of both qualitative and quantitative restrictions on international labor mobility individuals are distinguished in terms of their ability and age enabling the model to examine factors which influence the age and skill profile of those who migrate as well as the equilibrium flow of migrants and the pattern of factor rewards in the two economies effects of changes in certain parameters of the model are related to the nature of the immigration policy enforced by the host country the role of emigration restrictions is also considered excerpt

time preference and international labor migration abstract this paper analyzes the pattern and welfare implications of international labor migration within a dynamic general equilibrium model in a two country overlapping generations world labor migrates unilaterally from the high low to the low high time preference country if both countries under over invest relative to the golden rule bilateral migration a theoretical novelty occurs if the countries are on opposite sides of the golden rule steady state welfare analysis is conducted where in contrast to existing results unilateral migration immiserizes non migrants in the immigration country while making non migrants in the immigration country at least as well off bilateral migration may improve world welfare

justifying the first order approach to principal agent problems it is of interest to know when the incentive compatibility conditio n in principal agent problems can be replaced by the condition that the agent s expected utility be stationary in effort the mirrlees rogerson conditions do not work if the principal can observe more than one observable statistic also the mirrlees rogerson assumption that the distribution function of output is convex in the agent s action is unsatisfactory even in the context of the basi c model it is too restrictive the paper presents a suite of conditio ns that are applicable to the multistatistic case and replaces the objectionable convex distribution function assumption copyright 1988 by the econometric society

the effect of central bank independence on inflation in developing countries abstract ismihan and ozkan ismihan m ozkan f g 2004 does central bank independence lower inflation economics letters 84 305 309 provide theoretical support for prior studies empirical findings of positive or no significant relationship between central bank independence cbi and average inflation performance the present paper argues that these findings are spurious because the studies use an econometric methodology that does not account for the measurement error in their proxies for cbi this paper employs an econometric methodology that does account for this measurement error and finds a strong negative relationship between cbi and inflation even though the sample is limited to developing countries

the macroeconomic effects of distortionary taxation abstract prescott 1986 estimates that technology shocks account for 75 of the fluctuations in the postwar u s economy this paper reestimates the contribution of technological change for a standard business cycle model that includes a public sector and fiscal disturbances i find that a significant fraction of the variance of aggregate consumption investment output capital stock and hours of work can be explained by disturbances in labor and capital tax rates and government consumption i also use the model to quantify the welfare costs of capital and labor taxation for both the time series and welfare calculations maximum likelihood estimates of taste technology and policy parameters are used

competition through commissions and kickbacks in markets for retail financial products and health services consumers often rely on the advice of intermediaries to decide which specialized offering best fits their needs product providers in turn compete to influence the intermediaries advice through hidden kickbacks or disclosed commissions motivated by the controversial role of these widespread practices we formulate a model to analyze competition through commissions from a positive and normative standpoint the model highlights the role of commissions in making the advisor responsive to supply side incentives we characterize situations when commonly adopted policies such as mandatory disclosure and caps on commissions have unintended welfare consequences jel d21 d82 d83 g21 l15 l25

central bank independence and inflation good news and bad news abstract the bad news is that the findings of recent studies of central bank independence and inflation are very sensitive to outliers the good news is that evidence presented here reinforces the existing case for bank independence in high income economies

why do immigrant workers in australia perform better than those in canada is it the immigrants or their labour markets research comparing the labour market performance of recent cohorts of immigrants to australia and canada points to superior employment and earnings outcomes in australia examining australian and canadian census data between 1986 and 2006 we find that this performance advantage is not driven by differences in broader labour market conditions affecting all new labour market entrants rather the results from comparing immigrants from a common source country either the u k india or china suggest that australian immigrants perform better particularly in average earnings primarily because of a different source country distribution moreover the recent tightening of australian selection policy most notably its use of mandatory pre migration english language testing appears to be having an effect primarily by further shifting the source country distribution of immigrants away from non english speaking source countries rather than in identifying higher quality migrants within source countries pourquoi est ce que les travailleurs immigrants en australie s en tirent mieux que ceux qui choisissent le canada probleme d immigrants ou de marches du travail les recherches comparant la performance des recentes cohortes d immigrants sur le marche du travail en australie et au canada suggerent des resultats superieurs en australie tant pour ce qui est des niveaux d emploi que pour les niveaux de gains d emploi examinant les donnees de recensements au canada et en australie entre 1986 et 2006 on decouvre que cet avantage au niveau de la performance n est pas attribuable a des differences dans les conditions generales du marche du travail affectant tous les nouveaux entrants sur le marche du travail c est plutot qu en comparant les immigrants d une source commune d immigrants u k indes ou chine les resultats suggerent que les immigrants en australie s en tirent mieux en particulier pour ce qui est des gains moyens surtout a cause de la repartition differente des pays d origine de plus le resserrement recent de la politique de selection australienne en particulier son utilisation d un test obligatoire de connaissance de l anglais avant l immigration semble avoir eu pour effet de deplacer la repartition de la source des immigrants de maniere a diminuer l immigration en provenance de pays ou on ne parle pas l anglais plutot que d identifier des immigrants potentiels de plus haute qualite dans les divers pays d origine

the economic effects of immigration a dynamic analysis abstract this paper examines the economic effects of immigration using a neo classical growth model with overlapping dynasties we demonstrate that in contrast to the predictions of the static models often used in the analysis of immigration in a dynamic model with endogenous capital accumulation shifts in factor prices that result from changes in immigration policy will be very modest consequently benefits to natives from immigration are much smaller than previous studies have found and smaller still if labor supply is elastic on the other hand the adverse effects on wages are much smaller as well implying that in a model with only two inputs immigration plays a much smaller role in redistribution from labor to capital than previously thought

inflation and central bank independence a meta regression analysis using 59 studies we perform a meta regression analysis of studies examining the relationship between inflation and central bank independence cbi the studies considered are very different with respect to the cbi indicator used the sample of countries and time periods covered model specification estimators used and publication outlet we conclude that there is a significant publication bias however we also find a significant genuine effect of cbi on inflation differences between studies are not caused by differences in cbi indicators used

assimilation changes in cohort quality and the earnings of immigrants this paper reexamines the empirical basis for two facts that seem to be found in most cross section studies of immigrant earnings 1 the earnings of immigrants grow rapidly as they assimilate into the united states and 2 this rapid growth leads to many immigrants overtaking the earnings of the natives within 10 15 years after immigration using the 1970 and 1980 u s censuses this paper studies the earnings growth experienced by specific immigrant cohorts during the period 1970 80 it is found that within cohort growth is significantly smaller than the growth predicted by cross section regressions for most immigrant groups this differential is consistent with the hypothesis that there has been a secular decline in the quality of immigrants admitted to the united states

intertemporal substitution in labor supply evidence from micro data the sensitivity of the supply of labor to intertemporal variation in the wage is an important issue in macroeconomics the analysis of social security and pensions and the study of life cycle patterns of work this paper explores two approaches to the measurement of intertemporal substitution that have appeared in the literature the first approach is to use consumption to control for wealth and unobserved expectations about future wages in the labor supply equation the second approach is to estimate a first difference equation for hours in which labor supply from the previous period serves as a control for wealth and wage expectations the results indicate that intertemporal substitution elasticity for married men is positive but small

does central bank independence lower inflation this paper provides a potential explanation for the recent findings of no significant relationship between central bank independence cbi and lower inflation we argue that although cbi delivers lower inflation in the short term it may reduce the scope for productivity enhancing public investment and so harm future growth potential we also argue that the effects on growth make cbi less likely to achieve lower inflation in the long term

on evaluation costs in strategic factor markets the implications for competition and organizational design this paper uses a formal model to study how evaluation costs affect competition for resources in strategic factor markets it finds that relative scarcity may not always benefit resource sellers rather when competition among resource investors passes a certain threshold intensity miscoordination among investors increases to the point that sellers expected profits decline this paper extends the model to consider how investors organize to overcome managerial agency in resource evaluation two organizational designs are considered a incentivization wherein a lower level manager is motivated by an incentive contract to evaluate resources for an investor and b supervision wherein evaluation is either handled directly or closely monitored by headquarters the model suggests that competition among investors will be associated with a greater use of supervision and that investors using supervision will tend to make lower offers this paper also finds that supervision will be more common when valuable resources are rare this paper was accepted by bruno cassiman business strategy

contracting with private knowledge of signal quality we characterize the optimal procurement contract in a setting where a supplier has privileged knowledge of the quality of a public signal about his production costs the optimal contract exhibits important differences with standard contracts in adverse selection settings for instance the contract induces output both above and below first best levels furthermore the induced output may not vary with the realized public signal unless the signal quality is sufficiently pronounced in addition output may increase as expected costs increase

socially optimal procurement with tight budgets and rationing abstract we investigate the behaviour of a social planner that secures the supply of a good e g an environmental benefit through contracting with private agents while the social planner seeks to maximise net social benefits she is also controlled with a fixed budget private agents are profit maximising and hold private information concerning their variable costs of production they also have known fixed costs of contracting we find that budget constraints and fixed costs change the optimal contract design in more than one way the social planner minimises costs rations high cost contracts to reduce fixed costs and information rents and distorts contracts for all agent types including low cost agents we find that rationing improves social welfare also even though social costs including tax distortion are explicitly taken into consideration they do not affect the design of optimal contracts when budgets are tight in those cases the budget constraint dominates the solution

inflation and central bank independence revisited abstract king and ma economics letters 72 2001 95 claim that evidence which they report for a sample of 42 countries shows that central bank independence cbi and inflation are not significantly related the present paper argues that this putative failure of cbi to affect inflation is due to king and ma s use of an econometric methodology that does not account for the inaccuracy of their proxy for cbi employing an alternative econometric methodology that tackles the measurement error problem directly this paper finds a strong negative relationship between cbi and inflation

a complete solution to a class of principal agent problems with an application to the control of a self managed firm this paper considers a class of principal agent problems which have the following features 1 there is adverse selection because the principal ignores the value of one parameter of the agent s true characteristics 2 leaving aside the information parameter the principal s welfare as well as the agent s welfare depend on two types of variables observable to both of them the first ones possibly multidimensional are called action variable s and the second one which is one dimensional has in general the meaning of a money transfer 3 the principal is a stackelberg leader of the two person game he can commit himself to decision rules which are admissible on informational grounds he optimizes within the adequate class taking into account besides the agent s reaction one constraint which has generally the meaning of an individual rationality constraint and sometimes of a feasibility constraint the optimization is limited to the class of non stochastic mechanisms 4 the problem can also receive an alternative interpretation the principal faces a continuum of agents of unknown characteristics the distribution being known however stylized principal agent problems of this type have often been considered in the economic literature in particular the reader will later be able to recognize that the standard income tax model a la mirrlees 1971 the quality or quantity choice model of the monopolist a la mussa and rosen 1978 or maskin and riley 1982 and the model of government regulation of the private monopolist of baron and myerson 1982 all belong to

fiscal decentralization fiscal rules and fiscal discipline fiscal decentralization fd and fiscal rules fr are institutional mechanisms that are implemented by varying degrees in increasing number of countries this paper investigates empirically the effect of fr on the effectiveness of fd in achieving fiscal discipline panel evidence strongly supports that balanced budget and expenditure rules help fd to achieve this goal while debt rule has a direct disciplinary effect

delegated information acquisition with moral hazard abstract we analyze a principal agent problem with moral hazard where a principal searches for an opportunity of uncertain return and hires an agent to evaluate available options the agent s effort affects the informativeness of a signal about an option s return based on the information provided by the agent the principal decides whether to exercise the option at hand we derive properties of the optimal contract in both static and dynamic versions of the problem we show that there are intermediate values of the prior probability that the option is of high quality at which positive effort cannot be sustained we also show that if the prior is below a threshold then the agent is rewarded for delivering bad news about the option s quality we derive distortions relative to the first best on the implemented effort level and optimal stopping decision for some parameter values it is optimal for the principal to commit to an ex post suboptimal stochastic decision to exercise an option

entry and r d in procurement contracting abstract a model of competitive procurement and contracting is presented in this paper the key features of the model include precontract r d an endogenous number of homogeneous firms and sealed bid auction rules both diminishing and constant returns to scale drs and crs in r d expenditure technologies are considered i find that the sealed bid first price auction fpa is equivalent to the second price auction spa under drs technology the revenue equivalence theorems breaks down under crs because multiple equilibria arise in the r d stage when spa is used howerer spa yields a unique perfect equilibrium given sufficient heterogeneity among potential firms the free entry perfect equilibrium is also characterized the buyer prefers free entry through an appropriate selection of the reservation price

correlation and relative performance evaluation this paper reexamines the issue of relative versus joint incentive schemes in a multi agent moral hazard framework the model allows a full analysis of the information and dependence structure an important result is that the widespread notion that greater correlation in outcomes calls for more competition is not robust first when the dependence structure is effort sensitive the optimal incentive scheme in general mixes elements of relative evaluation and joint evaluation second under limited liability higher equilibrium correlation tends to make joint performance evaluation more desirable examples are provided regarding incentives in firms finance and innovation

fiscal implications of immigration a net present value calculation focusing on the net fiscal effects the gain from admitting immigrants is computed for a welfare state with large expenditures and a large tax burden sweden prices and behavior are held constant which allows a detailed analysis of the effects of immigration the present value of future tax revenues minus outlays is potentially large usd 23 500 per young working age immigrant but an average new immigrant represents a net government loss of usd 20 500 the dominant factors are employment rates and age for young working age immigrants the break even participation rate for which the gain would be zero is 60 well below the empirical rate for this group

on the political economy of deficit bias and immigration how much can governments shift the cost of their expenditure from today s voters to tomorrow s generations of immigrants without resorting to taxation that is explicitly discriminatory i demonstrate that if their societies are absorbing continuous flows of new immigrants we should expect governments that represent the interests of today s population to choose policies that shift some portion of the tax burden to the future even if that population is altruistically linked to future generations to measure the deficit bias i analyse the dynamic behaviour of an optimal growth model with overlapping dynasties and factor taxation calibrated for the us economy and consider the welfare implications for today s population and their descendants of intertemporal shifts in the tax rates on labour and asset income as well as transfer payments models with overlapping infinite lived dynasties allow for a very clear distinction between natural population growth an increase in the size of existing dynasties and immigration the addition of new dynasties they also provide an alternative to the strict dichotomy between models with overlapping generations where agents disregard the impact of their choices on future generations and the quasi ricardian world of infinite lived dynasties with representative agents that fully participate in both the economy and the political system in every period the trajectory of the debt burden predicted by the model is a good match for the rise in us federal government debt since the early 1980 s as well as the increases in debt projected by the congressional budget office over the next few decades

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

ignorance in agency problems we extend the standard agency model of adverse selection to incorporate the possibility that the agent may be ignorant i e know no more about a critical parameter than does the principal ignorance introduces a discontinuity pooling and particularly severe output distortions into the optimal incentive contract journal of economic literature classification numbers c79 d82

what drives the skill premium technological change or demographic variation abstract this paper quantitatively examines the effects of two exogenous driving forces investment specific technological change istc and the demographic change known as the baby boom and the baby bust on the evolution of the skill premium and the college enrollment rate in the postwar u s economy we develop a general equilibrium overlapping generations model with endogenous discrete schooling choice the production technology features capital skill complementarity as in krusell et al 2000 istc through capital skill complementarity raises the relative demand for skilled labor while demographic variation affects the skill premium by changing the age structure and hence the relative supply of skilled labor we find that istc is the key element driving the skill premium in the postwar u s economy and it is quantitatively important for the dynamics of the college enrollment rate the quantitative importance of the demographic change for the evolution of both the skill premium and the college enrollment rate however is limited

information control in the principal agent problem this paper compares the principal s payoff in agency models under different assumptions about the agent s access to information the agent may make decisions before is uninformed or after is informed learning the state of nature when there are two possible outcomes the principal typically prefers informed to uninformed agents whether the agent receives the information before or after contracting this result is false when there are more than two outcomes conditions under which a principal prefers one agent to another when the agents differ only in their disutility of effort are also given copyright 1993 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

the effect of immigration on public finances the impact of immigration on the public finances is an important influence on public opinion this study aims to provide a thorough conceptual survey pointing out the complexities of a full understanding and the relevance of indirect effects and covering both static perspectives and longer run dynamic issues it considers simple accounting approaches which are relatively neglectful of behavioural responses but also tries to bring out the complexities in the nature of the relationship between immigration and the public exchequer that come with more sophisticated modelling of its economic effects

evidence of new immigrant assimilation in canada previous studies of the labour market experience of male immigrants to canada have uncovered two disturbing trends declining entry earnings for successive new immigrant cohorts and low assimilation rates these findings suggest that many of these cohorts may never assimilate the 1991 census provides a first look at the immigrant cohorts arriving in the 1980s these immigrants appear to avoid the plight of their predecessors entry earnings have stopped falling and those immigrants arriving between 1981 and 1985 experienced a 17 per cent assimilation rate i am unable to explain this turnaround based on the observable characteristics recorded in the census data

pessimistic information gathering an agent gathers information on productivity shocks and accordingly produces on behalf of a principal information gathering is imperfect and whether it succeeds or not depends on the agent s effort contracting frictions come from the fact that the agent is pessimistic on the issue of information gathering and there are both moral hazard in information gathering private information on productivity shocks and moral hazard on operating effort an optimal menu of linear contracts mixes high powered productivity dependent screening options following good news with a fixed low powered option otherwise

an analysis of the principal agent problem most analyses of the principal agent problem assume that the principal chooses an incentive scheme to maximize expected utility subject to the agent s utility being at a stationary point an important paper of mirrlees has shown that this approach is generally invalid we present an alternative procedure if the agent s preferences over income lotteries are independent of action we show that the optimal way of implementing an action by the agent can be found by solving a convex programming problem we use this to characterize the optimal incentive scheme and to analyze the determinants of the seriousness of an incentive problem

regulating a monopolist with unknown costs we consider the problem of how to regulate a monopolistic firm whose costs are unknown to the regulator the regulator s objective is to maximize a linear social welfare function of the consumers surplus and the firm s profit in the optimal regulatory policy prices and subsidies are designed as functions of the firm s cost report so that expected social welfare is maximized subject to the constraints that the firm has nonnegative profit and has no incentive to misrepresent its costs we explicitly derive the optimal policy and analyze its properties in their classic papers dupuit 2 and hotelling 5 considered pricing policies for a bridge that had a fixed cost of construction and zero marginal cost they demonstrated that the pricing policy that maximizes consumer well being is to set price equal to marginal cost and to provide a subsidy to the supplier equal to the fixed cost so that a firm would be willing to provide the bridge this first best solution is based on a number of informational assumptions first the demand function is assumed to be known to both the regulator and to the firm while the assumption of complete information may be too strong the assumption that information about demand is as available to the regulator as it is to the firm does not seem unnatural a second informational assumption is that the regulator has complete information about the cost of the firm or at least has the same information about cost as does the firm this assumption is unlikely to be met in reality since the firm would be expected to have better information about costs than would the regulator as weitzman has stated an essential feature of the regulatory environment i am trying to describe is uncertainty about the exact specification of each firm s cost function in most cases even the managers and engineers most closely associated with production will be unable to precisely specify beforehand the cheapest way to generate various hypothetical output levels because they are yet removed from the production process the regulators are likely to be vaguer still about a firm s cost function 12 p 684 as this observation suggests it is natural to expect that a firm would have better information regarding its costs than would a regulator the purpose of this paper is to develop an optimal regulatory policy for the case in which the regulator does not know the costs of the firm one strategy that a regulator could use in the absence of full information about costs is to give the firm the title to the total social surplus and to delegate the pricing decision to the firm in pursuing its own interests which would then be to maximize the total social surplus the firm would adopt the same marginal cost pricing strategy that the regulator would have imposed if the regulator had
