the forecasting ability of correlations implied in foreign exchange options abstract this paper evaluates the forecasting accuracy of correlations derived from implied volatilities in dollar mark dollar yen and mark yen options from january 1989 to may 1995 as a forecast of realized correlation between the dollar mark and dollar yen implied correlation is compared against three alternative forecasts based on time series data historical correlation riskmetrics exponentially weighted moving average correlation and correlation estimated using a bivariate garch 1 1 model at the 1 month and 3 month forecast horizons we find that implied correlation outperforms often significantly these alternative forecasts in combinations implied correlation always incrementally improves the performance of other forecasts but not the converse in certain cases historically based forecasts contribute no incremental information to implied forecasts the superiority of the implied correlation forecast holds even when forecast errors are weighted by realized variances reflecting correlation s contribution to the dollar variance of a multicurrency portfolio

the forward market in emerging currencies less biased than in major currencies abstract many studies have replicated the finding that the forward rate is a biased predictor of the future change in the spot exchange rate usually the forward discount actually points in the wrong direction but at least until recently those studies applied only to advanced economies and major currencies we apply the same tests to a sample of 14 emerging market currencies we find a smaller bias than for advanced country currencies the coefficient is on average positive i e the forward discount at least points in the right direction it is never significantly less than zero to us this suggests that a time varying exchange risk premium may not be the explanation for traditional findings of bias the reasoning is that emerging markets are probably riskier yet we find that the bias in their forward rates is smaller emerging market currencies probably have more easily identified trends of depreciation than currencies of advanced countries

how should we incentivize private landowners to produce more biodiversity globally much biodiversity is found on private land acting to conserve such biodiversity thus requires the design of policies which influence the decision making of farmers and foresters in this paper we outline the economic characteristics of this problem before reviewing a number of policy options such as conservation auctions and conservation easements we then discuss a number of policy design problems such as the need for spatial coordination and the choice between paying for outcomes rather than actions before summarizing what the evidence and theory developed to date tell us about those aspects of biodiversity policy design which need careful attention from policy makers and environmental regulators

fiscal versus traditional market variables in canadian migration this paper evaluates the hypothesis that the influence of traditional market variables on migration in canada has diminished over time this is attributed to a crowding out process whereby growth of social security type programs has cushioned the effects of say unemployment and thus motivation to migrate for jobs and fiscal policies have exerted unintended effects implications are that market forces that would work naturally to induce migration from low to high income regions and thus equalize earned incomes have been short circuited and that traditional tools of manpower policy for influencing migration such as job creation skill enhancement or wages are less effective currently than they might have been in the past

decentralization and intra country transfers in the great recession the case of the european union empirical evidence is found supporting the assignment of the redistribution function to the central government viewing the great recession or recessions in general as a shock it is found that a

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

decentralized income redistribution reconsidered decentralized income redistribution reconsidered i introduction which is the appropriate level of government to undertake income redistribution this issue is receiving renewed attention from economists examining how migration and labor supply responses affect the costs of transfer payments at the state or federal level in a recent paper brown and oates 1987 use a formal public choice model to show that the possibility of migration of transfer recipients between states leads to suboptimal transfer levels even when taxpayers care only about transfer recipients within their own states with benefit spillovers across states their argument for federal responsibility for redistribution is presumably even stronger gramlich 1985 also argues that migration is large enough to lead to suboptimal levels of transfers at the state level because states with low benefit levels will be able to export their poor increasing the cost of redistribution to high benefit states gramlich s conclusion is based on the empirical work in gramlich and laren which finds that the migration effect is very strong though only in the very long run 1984 510 the implicit argument is that migration raises the cost of redistribution at the state level compared to the federal level 1 however neither brown and oates nor gramlich consider labor supply responses that is hours and participation in their analyses on the other hand several recent papers have attempted to estimate the cost of redistribution at the national level incorporating labor supply responses to taxes and transfers but not interjurisdictional migration 2 some empirical evidence is available which is consistent with either migration or labor supply effects for example helms 1985 uses time series cross section data on state expenditure and tax policies and finds that while spending on public services schools highways etc increases personal income increased state transfer payments financed by state taxes significantly reduce total state personal income this reduction could be caused by either migration or labor supply responses to taxes and transfers indeed helms s estimates indicate a very large response to transfer spending one more dollar of transfers reduces state personal income in the long run by 14 83 helms concludes states which seek to devote substantial tax revenues to transfer payments will experience significantly reduced growth prospects which limits the scope for redistribution at the state and local levels 1985 581 a concise summary of the standard argument concerning federalism and redistribution might be as follows 1 interstate migration of taxpayers and transfer recipients raises the taxpayer cost of income redistribution at the state level above the cost at the federal level 2 state wide redistribution confers spillover benefits to residents of other states 3 therefore as compared with a national system decentralized responsibility for income redistribution yields a less redistribution because its cost is higher and b less than the socially optimal amount of redistribution because of externalities my 1988 paper shows that step 1 of the above argument is not necessarily true because the migration effect which previous authors have stressed can be offset by a tax exporting effect by which residents of one state shift some of the fiscal cost of redistribution to residents of other states both the income effect and the substitution effect of increased redistribution will reduce the labor supply and hence earnings of transfer recipients the labor supply and earnings of taxpayers may also fall if substitution effects are strong enough the tax exporting effect arises if taxes and transfers on net reduce total earnings in a state since the state s federal tax obligations depend on its earnings

welfare payments and other economic determinants of female migration this article investigates the effects of welfare payments wages and unemployment on women s probability of interstate migration in the united states it also investigates if the income attraction of locations varies with recency of labor market experience welfare gains increase the probability of interstate migration welfare effects are largest for single mothers with small children and stronger among women with no recent labor market experience the welfare effects albeit small are larger than the wage effects the wage effects are weaker among women with no recent work experience ethnic specific analyses suggest differences in migration behavior among anglos african americans and puerto ricans

numerical solutions to nash cournot equilibria in coupled constraint electricity markets a numerical method based on a relaxation algorithm and the nikaido isoda function is presented for the calculation of nash cournot equilibria in electricity markets nash equilibrium is attained through a relaxation procedure applied to an objective function the nikaido isoda function which is derived from the existing profit maximization functions calculated by the generating companies we also show how to use the relaxation algorithm to compute and enforce a coupled constraint equilibrium which occurs if regulatory generation and distribution and more restrictions are placed on the companies and entire markets moreover we use the relaxation algorithm to compute players payoffs under several player configurations this is needed for the solution of our game under cooperative game theory concepts such as the bilateral shapley value and the kernel we show that the existence of both depends critically on demand price elasticity the numerical method converges to a unique solution under rather specific but plausible concavity conditions a case study from the ieee 30 bus system and a three bus bilateral market example with a dc model of the transmission line constraints are presented and discussed

the relationship between the renminbi future spot return and the forward discount rate abstract we use rolling cointegration tests to investigate the relationship between the renminbi daily future spot return and the forward discount rate for the period after the currency regime reform in china in july 2005 we find that there are different regimes after this reform and that the financial crisis affects the relationship between the future spot return and the forward discount rate in china the unbiasedness hypothesis that the forward rate is an unbiased predictor of the future spot rate requires cointegration and a unity coefficient for the forward discount we conclude that the unbiased forward rate hypothesis only holds in spring 2009 when the chinese authorities returned to pegging the renminbi to the us dollar to overcome the turmoil of the global financial crisis

migration and income redistribution responsibilities this study examines whether afdc benefits determine or discourage state to state migration flows in the united states a pooled cross section time series model is developed to estimate afdc benefits in a state and recipients and whether benefits in one state affect benefits in other states a second model using data from the 1980 census and the panel study of income dynamics estimates migration of afdc recipients and the level of benefits in in migration and out migration states both models indicate that small but statistically significant amounts of migration occur which may be quite important but only in the long run movers although small in number are much more likely to move to a state with higher benefits states perceive this migration as important indicating that states should have less control and the federal government more control over income redistribution

the effect of welfare and wage levels on the location decisions of female headed households abstract this paper develops and estimates a model designed to calculate the impact of welfare benefit levels wages and tax rates on the location choices of female headed households the empirical model assumes that women simultaneously choose both where they will live and whether or not they will participate in the welfare system based on their expected income and expected hours of work for each location participation possibility these income and hours expectations depend in turn on the welfare benefits wage and tax rates facing each household in each location it is found that both regional welfare levels and wage rates have a significant effect on the location decisions of this population the probability of a typical female headed household with little outside income leaving an area with low welfare payments and low wages can be as much as 12 points higher over a 4 year period than the probability of leaving a high welfare high wage area

the forward premium anomaly and the trend behavior of the exchange rates abstract it is found that the forward premium and the change in the spot exchange rate have rather different time series properties and trend behavior this study shows that the reported finding of the forward premium anomaly may partially stem from the underspecification of deterministic variables in the model the results of the study appear to be consistent with the peso problem proposition of interpreting the forward premium anomaly

assessing the performance of conservation auctions an experimental study this work uses controlled laboratory experiments to investigate the budgetary and the economic performance of competitive tenders for allocating conservation contracts to landholders experiments have been replicated in two different countries to check for robustness of results we find that auctions outperform the more traditional fixed price programs only in the one shot setting with repetition the auctions quickly lose their edge the budget constrained auction performs similarly to the target constrained in the one shot setting but appears more robust to repetition our results suggest that previous estimates of conservation auction performance are too optimistic and we propose a method for improving such estimates

the foreign exchange market a random walk with a dragging anchor this paper explores some anomalies in the foreign exchange market it is hard to find evidence of either short term overshooting or of longer term reversion to an equilibrium the forward exchange rate contains virtually no information on future spot rates discussions with practitioners indicate that longer term speculation based on fundamentals is strictly limited and survey data and other evidence suggest that expectations and speculation are based on a variety of models the interplay between speculation based on fundamentals and on a random walk or chartist approach influences the outcome this endorses the prior model of j a frankel and k a froot copyright 1988 by the london school of economics and political science

using survey data to test standard propositions regarding exchange rate expectations survey data provide a measure of exchange rate expectations superior to the forward rate in that no risk premium interferes we estimate extrapolative adaptive and regressive models of expectations static or random walk expectations and bandwagon expectations are rejected current appreciation generates the expectation of future depreciation because variables other than the contemporaneous spot rate receive weight in comparing expectations to the process governing the spot rate we find statistically significant bias no variable is as ubiquitous in international financial theory and yet as elusive empirically as investors expectations regarding exchange rates in the past expectations have been modeled in an ad hoc way often by using the forward exchange rate there is however a serious problem with using the forward discount as the measure of the expected change in the exchange rate in that the two may not be equal the gap that may separate the forward discount and expected depreciation is generally interpreted as a risk premium most of the large empirical literature testing the unbiasedness of the forward exchange rate for example has found it necessary either arbitrarily to assume away the existence of the risk premium if the aim

locational choice of afdc recipients within california a conditional logit analysis abstract this paper examines factors that influence migration of afdc recipients within california a county level conditional logit model is used to analyze the impact of cost adjusted benefits on intrastate moves during recipients first year of welfare participation costs of living particularly housing costs differ considerably across counties of california yet the welfare benefit is set at the state level this creates the potential for variation in the purchasing power of the welfare benefit if a family chooses to move variation in cost of living is shown to have a significant effect on migration patterns of afdc recipients estimates suggest that a 150 decrease in fair market rent results in 15 more migration to the county recipients migration is more responsive to cost of living than migration of the general population

budget spillovers and fiscal policy interdependence evidence from the states abstract this paper formalizes and tests the notion that states expenditures depend on the spending of similarly situated states we find that even after allowing for fixed state effects year effects and common random shocks among neighbors a state government s level of per capita expenditure is positively and significantly affected by the expenditure levels of its neighbors ceteris paribus a one dollar increase in a state s neighbors expenditures increases its own expenditure by over 70 cents

nonmonotonic demand for income redistribution benefits the case of afdc two different motives are often advanced to explain taxpayer nonrecipient support for income redistribution programs the first motive is the result of interdependent utilities between nonrecipients and the recipients of redistribution program benefits the source of this interdependence could be taxpayer altruism alternatively redistribution might be seen as one way to alleviate the potential for crime or social unrest recent theoretical analyses have suggested a second motiveincome redistribution programs act as protection against the possibility of unforseen loss in personal income 5 6 21 32 researchers using panel data find widespread random and temporary movements in individual income poverty and welfare program use that would seem to suggest a potentially significant insurance demand for redistribution programs 2 the results from one study for example indicate that while four to five percent of the total u s population could be classified as persistent recipients of welfare program benefits between 1969 and 1978 receiving program benefits in at least five of those years over one quarter of the u s population participated in welfare programs at least once over this same ten year period 9 74 in the past researchers estimating nonrecipient support for income transfer programs have considered only one of these two motives while ignoring the other 3 this paper extends the examination of the demand for income redistribution by integrating the public good and social insurance demand motives into one model the first part of the paper sets up the individual s decision model for income redistribution one consequence of interacting the public good and social insurance motives into one model is that support for higher benefit payments is expected to come from the tails of the income distribution low income individuals both recipients and nonrecipients benefit directly from the reduced risk of income randomness while high income

a model of welfare competition with evidence from afdc in this paper we test empirically for strategic behavior among the states using the cash support program aid to families with dependent children afdc to motivate the empirical work we adapt wildasin s model of income redistribution 1991 american economic review 81 757 773 to a model of interjurisdictional welfare competition although welfare competition may be generated from different frameworks we choose wildasin s model to illustrate how welfare benefit interdependence is genereated in the context of welfare migration we estimate a representative reaction function for afdc using both cross sections and pooled cross section data after controlling for other determinants of afdc benefit levels and for spatial error autocorrelation we find evidence showing competition 2000 academic press

auctions with endogenous quantity this article studies auctions in which several sellers compete for the right to sell to a market characterized by a negatively sloped demand curve in this environment the quantity traded becomes endogenous this effect leads to three results concerning the outcomes of open versus first price sealed bid auctions first an open auction yields a higher expected price than does sealed bidding second and more important the open auction captures less of the potential gains from trade than does the sealed bid auction third for broad classes of demand curves the efficiency gains from switching to sealed bids from an open auction accrue to both sellers and the buyer so that all concerned parties would agree to the change a direct application of the theory is to procurement the heavy use of sealed bidding in procurement is seen as rational in light of these results auction models with endogenous quantity could be an alternative to price setting oligopoly models for the study of price formation in general for the latter impose strong information requirements on agents and yield only equilibrium price vectors not equilibrium processes for determining prices

covariance matrix estimators and tests of market efficiency abstract this paper carries out multi currency multi horizon and combined tests of simple market efficiency using alternative covariance matrix estimators whose finite sample performances have been examined elsewhere in the literature the data utilized are properly aligned weekly exchange rates from june 1973 to december 1994 on bid spot 1 month 3 month and 6 month ask forward rates for several currencies the results demonstrate that tests of market efficiency are sensitive to the information set specified the prediction horizon considered and the covariance matrix estimator employed in most but not all cases rejections of market efficiency are overturned using a prewhitened heteroskedasticity and autocorrelation consistent covariance matrix estimator with optimal asymptotic properties and better finite sample performance

the effect of the social welfare system on metropolitan migration in the us by income group gender and family structure this research paper addresses some important issues regarding out migration from and in migration to metropolitan areas in the u s particularly the effect of the social welfare system on migration decisions the primary focus is on migration by income group poor versus non poor with a secondary focus on how gender and family status relate to migration the results provide only very weak support for the hypothesis that social welfare benefits influence out migration decisions only of non poor female headed households but moderate support for the effect of such benefits on in migration decisions especially of low income and female headed households excerpt

accounting for forward rates in markets for foreign currency absteract forward and spot exchange rates between major currencies imply large standard deviations of both predictable returns from currency speculation and of the equilibrium price measure the intertemporal marginal rate of substitution representative agent theory with time additive preferences cannot account for either of these properties we show that the theory does considerably better along these dimensions when the representative agent s preferences exhibit habit persistence but that the theory fails to reproduce some of the other properties of the data in particular the strong autocorrelation of forward premiums since the advent of flexible exchange rates in the early 1970s a large body of statistical work has established that forward rates for major currencies are not optimal predictors of future spot rates relevant evidence is reported in studies by baillie lippens and mcmahon 1983 bekaert 1991 bilson 1981 boothe and longworth 1984 cumby 1988 cumby and obstfeld 1984 fama 1984 gregory and mccurdy 1984 hansen and hodrick 1983 hodrick and srivastava 1984 and korajczyk and viallet 1990 a more complete list of references is provided by hodrick 1987 these papers indicate that returns from speculation in forward and spot currency markets are predictable and that the predictable components vary considerably over time a number of alternative explanations have been offered for the predictable variation in foreign currency market excess returns kaminsky 1988 korajczyk 1985 and krasker 1980 suggest that infrequent extreme events may make returns appear predictable in small samples the so called peso problem lewis 1989 argues that rational learning following infrequent changes in the process governing equilibrium prices can explain part of the ex post predictability of currency returns froot and frankel 1989 and froot and thaler 1990 examine the hypothesis that market forecasts of future spot

anomalies foreign exchange most all behavior can be explained by assuming that agents have stable well defined preferences and make rational choices consistent with those preferences in markets that eventually clear an empirical result qualifies as an anomaly if it is difficult to rationalize or if implausible assumptions are necessary to explain it within the paradigm this column will present a series of such anomalies readers are invited to suggest topics for future columns by sending a note with some reference to or better yet copies of the relevant research comments on anomalies printed here are also welcome the address

the political economy of state level welfare benefits several new relationships ware indicated by this study first the percentage of adults with a college degree seems to increase welfare spending as noted above this does not necessarily imply that this group is particularly altruistic overall higher afdc levels could be encouraged by a politically productive minority in this group second the percentage black in the population is a better predictor of afdc levels than is the percentage of black afdc recipients that is discrimination against blacks via lower afdc levels is more closely related to the relative size of the black community than the relative size of the black welfare population the results suggest similar discrimination against hispanics in regard to afdc levels the percentage catholic increases afdc levels this does not necessarily imply that catholics have a higher preference for welfare spending than non catholics although this may be the case it may reflect the effect of pressure from catholic interest groups since catholics are the largest religious group in most states they may be better able to support political pressure groups that demand more generous welfare programs union pressures may contribute to higher levels of welfare benefits this is more likely to be the case when unemployment levels are particularly high the relative size of the poverty population is not significantly related to benefit levels the greater cost to taxpayers of increasing benefit levels when the poverty group is large seems to offset the rent seeking efforts of a larger recipient group finally jurisdiction size play a significant role in determining benefit levels with larger states providing more generous benefits in general the results suggest that the influence of rent seeking recipients is not a dominant factor in explaining afdc benefit levels this result is not surprising given the lack of political influence of this particular recipient group it is likely that rent seeking behavior is more important among more politically active groups such as social security recipients and public employees the influence of altruistic motives in affecting aid levels is more subtle than has been suggested in many past studies income was not found to be an important direct determinant of afdc levels the presence of altruistic motives coupled with the ability to effectuate these desires politically seems to be the key to explaining this type of transfer

afdc benefits and the inter urban variation in poverty among female headed households the percentage of families headed by females in poverty varies widely across metropolitan areas for example 8 37 of all families in albany georgia were female headed and in poverty in 1980 while in sheboygan wisconsin the figure was 1 1 though not as dramatic as this interregional difference intra regional variation can also be significant in detroit michigan 4 90 of families were femaled headed and in poverty and in the closest interstate metropolitan area toledo ohio the figure was 3 77 recent research into the behavior of low income femaleheaded families suggests that state benefit differentials in aid to families with dependent children afdc may in part be responsible in this paper we construct a model that explains an important and overlooked implication of non uniform benefit standards among states the inter urban variation in the size of the potential and actual afdc recipient population particular attention is given to 1 the impact of interurban differences in real afdc payments 2 the potential of afdc to alter the number of female headed families in poverty and 3 the relative importance of other urban characteristics in explaining the size of the potential and actual afdc recipient population the model uses 1980 census data and is estimated for all standard metropolitan statistical areas for which we were able to obtain data

the micromechanics of the federal funds market implications for day of the week effects in funds rate variability the federal funds rate arguably is the most important interest rate in the u s capital market because it plays a central role in monetary policy and the term structure this paper examines the micromechanics of the funds market we show that in a continuous market with asynchronous trading regulatory constraints and accounting conventions that focus agents attention on discrete time instants have important implications for the dynamics of trading activity and realized market prices we also exhibit a model of the market that explains observed regularities in the intertemporal behavior of the funds rate

tiebout or not tiebout the market metaphor and america s devolution debate the market metaphor of intergovernmental choice as a spur to efficiency formalized by charles m tiebout is often invoked to support the shift away from washington and toward the states but the model translates badly to governments governmental entry and exit is costly public sector co11usion often serves citizens interests heterogeneous mobility distorts the signals sent by interstate migration and while tiebout and followers condition efficiency predictions on optimal distribution the u s devolution movement coincides with rising inequality and has gone furthest where distribution matters most the metaphor is misapplied devolution will likely do more to enfeeble government than to improve it

exchange rate volatility and deviations from unbiasedness in a cash in advance model abstract this paper examines time series properties of exchange rate changes the forward premium and the forward bias in the context of a variant of svensson s cash in advance model the model is solved and simulated using realistic forcing processes whose law of motion is estimated from u s japan data and then approximated by a markov chain although method of moments estimation shows that the over identifying restrictions implied by the model are not rejected it fails dramatically in producing a sufficiently variable risk premium on forward market speculation this result is robust to various pertubations to the model s parameters forcing processes and preference structure the model also fails to match exchange rate and forward premium volatility simultaneously

american federalism welfare policy and residential choices the relationship between welfare benefit levels and the residential choices of the poor raises two issues for federalism in the united states do state benefit levels affect the residential choices of the poor do residential choices of the poor affect the level at which a state sets its benefit levels empirical studies have seldom studied the interconnection between these two issues this research estimates simultaneously the mutual effects of welfare benefits and poverty rates while controlling for other economic and political variables when benefit levels become high the size of the poverty population increases conversely when poverty rates become high benefit levels are cut the findings are consistent with the claim that state determined benefit levels distort policy and residential choices

conservation when landowners have bargaining power continuous conservation investments and cost uncertainty spatially heterogeneous costs of securing conservation agreements should be accounted for when prioritizing properties for conservation investment most researchers incorporating conservation costs into analyses have relied on estimates of landowners opportunity costs of accepting a conservation agreement implicitly assumed in such studies is therefore that those who produce biodiversity landowners receive none of the surplus available from trade instead landowners could use their bargaining power to gain profits from conservation investments we employ game theory to determine the surplus landowners could obtain in negotiations over conservation agreements and the consequent effects on conservation outcomes when enrolment decisions are governed by continuous variables e g the proportion of a property to enrol in addition we consider how landowner uncertainty regarding the opportunity costs of other landowners affects these outcomes landowners ability to gain surplus is highly variable and reflects variation in the substitutability of different properties for achieving a specified conservation objective the ability of landowners to obtain profits from conservation agreements results in conservation outcomes that are substantially diminished relative to when landowners accept investment at opportunity costs uncertainty increases landowner profits leading to a greater diminution in conservation benefits

migration the life cycle and state benefits how low is the bottom i show that among women likely to use welfare movers move to higher benefit states i also find that the probability likely welfare users will move at all is lower in higher benefit states this effect is concentrated early in the life cycle as theory predicts i construct a theoretical framework to measure the impact of welfare migration on optimal state benefits simulation results suggest little impact in higher benefit states but possibly a more substantial impact in other states finally evidence suggests little reason for concern due to welfare migration in using cross state variation in welfare generosity to identify incentive effects of the welfare system on other outcome variables

will farmers trade profits for stewardship heterogeneous motivations for farm practice selection we investigate the trade off agricultural producers face between profits and stewardly activities when selecting farm practices instead of the profit maximization framework we model producer behavior in an expanded utility framework built on production technology and including two utility components self and social interests the framework introduces inherent heterogeneity and social environmental motivations into farmer behavior based on this model we hypothesize that there are farmers that are willing to forego some profit to engage in stewardly farm practices with an empirical study we provide evidence that some farmers are willing to make this sacrifice results are consistent with the multi utility hypothesis

establishing the micro foundations of a macro theory information movers and the competitive local market for public goods e tiebout model of competition in the local market for public goods is an important and controversial theory the current debate revolves around the apparent disparity between macro 5 x empirical studies that show greater efficiency in the supply of public goods in polycentric regions compared to consolidated ones and micro evidence of widespread citizen consumer ignorance which has been used to argue that individual actions cannot plausibly lead to efficiency enhancing competition between local governments we argue that competitive markets can be driven by a subset of informed consumers who shop around between alternate suppliers and produce pressure for competitive outcomes from which all consumers benefit using data from a survey of overfive hundred households we analyze the role of these marginal citizen consumers and incorporate the costs of information gathering and the strategic interests of local governments into the competitive market model

the road less travelled institutional aspects of data and their influence on empirical estimates with an application to tests of forward rate unbiasedness the difference between data used in empirical studies and that envisioned in the theory can influence empirical estimates sometimes by enough that the direction of future research is altered this paper illustrates how in the context of tests of forward rate unbiasedness a lack of articulation about the mechanics underlying foreign exchange market speculation and about the institutional aspects governing spot and forward rate contracts leads to sampling of the data in a way that is not consistent with the theory the authors find that the sampling problems account for some but not all of the bias in the coefficient on the forward premium copyright 1996 by royal economic society

a reconsideration of the uncovered interest parity relationship abstract this paper argues that the uncovered interest parity uip relationship is distinct from and more important than the unbiasedness of forward exchange rates as predictors of future spot rates the standard finding that the slope estimate b is roughly 3 in regressions of s t on t 1 s t 1 implies rejection of unbiasedness but not necessarily uip the hypothesis that monetary authorities manage interest rates so as to smooth their movements while also resisting changes in exchange rates is attractive conceptually and is capable of explaining not only the b 3 finding but also several other notable features of the data

welfare policies and migration of the poor in the united states an empirical note this paper has investigated the impact of geographic welfare benefit differentials upon migration in the united states unlike other related studies which typically focus upon black migration as a surrogate measure of migration of the poor the present study focuses directly upon migration of the poor per se a variety of reduced form estimates are provided the evidence strongly suggests that the net in migration of the poor is positively and significantly influenced by higher nominal afdc levels and by higher real afdc levels these findings support the welfare magnet hypothesis which alleges that relatively high welfare levels act to attract poor migrants moreover given that poor migrants are attracted non only by high nominal welfare levels but also by high real welfare levels an argument can be made for establishing geographically uniform real welfare benefit levels in the united states this uniformity presumably should act over the long run to eliminate the human resource distortions being caused by the currently prevailing welfare system

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

an empirical investigation of interstate afdc benefit competition claims that states which offer generous welfare benefits attract the poor and that some states pay low benefits intending to drive the poor away are neither uncommon nor entirely un founded this paper employs a two player state generalized game to model states choice of a benefit level in the aid to families with dependent children afdc program migration by the poor in response to interstate differentials in earnings and welfare opportunities and the subse quent changes in afdc caseloads drive this game estimation of the model using 1979 data suggests that states within approximately 750 miles of each other do engage in a benefit setting game the rival s initial number of poor and preference for non afdc consumption appear to be the more influential rival characteristics these findings while derived from a different methodological approach are consistent with previous studies which indicate that welfare recipients tend to move toward higher benefit states such migration may impede the efficient spatial allocation of labor the results also indicate that states will tend to offer lower benefits given recipient migration than would be the case otherwise state jurisdiction over benefits consequently leads to underprovision of afdc federalization of the afdc program would improve efficiency in terms of the spatial allocation of labor and the provision of afdc

bertrand competition when rivals costs are unknown the conclusions of the bertrand model of competition are substantially altered by the presence of asymmetric information about rivals costs asymmetric information eliminates the discontinuity in the bertrand model and significantly alters the properties of the market equilibrium in the bertrand nash equilibrium when rivals costs are unknown firms price above marginal cost and have positive expected profit the analysis is extended to franchise competition the market equilibrium is sensitive to market structure and yields incentives for entry copyright 1995 by blackwell publishing ltd

welfare induced migration at state borders new evidence from micro data abstract this paper extends and synthesizes the various approaches used in the recent welfare migration literature to both offer the most comprehensive set of tests to date for welfare migration and to also determine the relative importance of short distance moves in welfare migration flows the current study follows on the finding of mckinnish mckinnish t importing the poor welfare magnetism and cross border welfare migration journal of human resources 2005 40 57 76 of welfare migration effects obtained by comparing welfare participation at state borders to state interiors this identification strategy is extended to micro data from the 1980 and 1990 decennial censuses and combined with the demographic comparisons used elsewhere in the welfare migration literature the signs and patterns of the estimates are consistent with the presence of welfare migration effects and the magnitudes of the estimates are consistent with the importance of short distance moves in welfare induced migration flows but most of the estimates are not statistically significant

immigration and welfare magnets this article investigates if the location choices made by immigrants when they arrive in the united states are influenced by the interstate dispersion in welfare benefits income maximizing behavior implies that foreign born welfare recipients unlike their native born counterparts may be clustered in the states that offer the highest benefits the empirical analysis indicates that immigrant welfare recipients are indeed more heavily clustered in high benefit states than the immigrants who do not receive welfare or than natives as a result the welfare participation rate of immigrants is much more sensitive to changes in welfare benefits than that of natives

welfare reform and the race to the bottom theory and evidence economists have argued that welfare migration leads to a race to the bottom in the choice of welfare benefits although a system of federal matching grants can remedy this problem the recent welfare reform law replaced the existing matching grant structure with block grants a policy change that appears undesirable to judge whether this critique of welfare reform is justified this paper evaluates the evidence in favor of a race to the bottom after explaining the theoretical effects of welfare migration the paper surveys the empirical evidence on the occurrence of such migration concluding that the evidence is mixed the discussion also considers recent empirical tests for strategic interaction which show that benefit levels in nearby states affect a given state s benefit choice the most plausible source of such interaction is a concern about welfare migration which leads policymakers to look at benefits in neighboring states when making their own choices judging that the evidence appears consistent with the existence of a race to the bottom the paper concludes that the demise of matching grants may be undesirable from a policy perspective
