nonstationary term premia and cointegration of the term structure this paper proposes a model of the term structure with nonstationary term premia which exhibit a factor structure this explains the common empirical finding of a cointegrating rank smaller than the one predicted by the rational expectations hypothesis of the term structure an application to german interest rate data yields easily interpretable results

do better schools matter parental valuation of elementary education the evaluation of numerous school reforms requires an understanding of the value of better schools given the difficulty of calculating the relationship between school quality and student outcomes i turn to another method and use house prices to infer the value parents place on school quality i look within school districts at houses located on attendance district boundaries houses then differ only by the elementary school the child attends i thereby effectively remove the variation in neighborhoods taxes and school spending i find that parents are willing to pay 2 5 percent more for a 5 percent increase in test scores this finding is robust to a number of sensitivity checks

interconnectivity of communications networks and international trade in this study a multi country model of trade is developed that captures the role of country specific communications network interconnectivity which enhances trade in intermediate business services the number of countries connected to inter nationally interconnected networks is found to determine the structure of comparative advantage that is countries with interconnected networks have a comparative advan tage in the good that requires business services provided via networks in connected countries producers of that good benefit from the efficient transmission of business services this research also demonstrates that countries whose country specific net works are not connected to the interconnected networks may become worse off as the

network externalities discrete demand shifts and submarginal cost pricing the introduction of a new product often causes a massive discrete demand shift to the new product this study demonstrates that if a large scale demand shift to a new product is accompanied by network externalities it may result in submarginal cost pricing by which the seller sets its price below the marginal cost this finding casts new light on dumping and safeguard issues in the real world jel classification d42 externalites de reseaux deplacements discrets de la demande et tarification en deca du cout marginal l introduction d un nouveau produit engendre souvent un deplacement massif discret de la demande vers le nouveau produit cette etude montre que si un tel deplacement de la demande est accompagne d externalites de reseaux il peut s ensuivre une tarification en deca du cout marginal ou le vendeur fixe son prix en dessous du cout marginal ce resultat jette une lumiere nouvelle sur les problemes de dumping et de protection dans le monde reel

voluntary export restraints and expectations an analysis of export quotas in oligopolistic markets the frequency of export quotas imposed as voluntary export restraints has been increasing this tends to create the expectation that similar export quotas will be imposed in the future even if free trade is allowed now the author analyzes the effect of such an expectation he demonstrates that if a quota is expected to be imposed on foreign exporting firms it intensifies the exporting firms competition in the prequota period this offsets the protection which the export quota as a voluntary export restraint will provide for domestic import competing firms in the future quota period copyright 1989 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

treasury yield curves and cointegration previous studies find that there is only one common stochastic trend in a set of interest rate series the result is interpreted as the evidence for supporting the expectations hypothesis cf hall et al 1992 this study finds that there are three common stochastic trends when whole spectrum stucture is analysed the three common stochastic trends can be interpreted as the shift the slope and the curvature of the term structure

does hazardous waste matter evidence from the housing market and the superfund program this paper uses the housing market to develop estimates of the local welfare impacts of superfund sponsored cleanups of hazardous waste sites we show that if consumers value the cleanups then the hedonic model predicts that they will lead to increases in local housing prices and new home construction as well as the migration of individuals that place a high value on environmental quality to the areas near the improved sites we compare housing market outcomes in the areas surrounding the first 400 hazardous waste sites chosen for superfund cleanups to the areas surrounding the 290 sites that narrowly missed qualifying for these cleanups we find that superfund cleanups are associated with economically small and statistically insignificant changes in residential property values property rental rates housing supply total population and types of individuals living near the sites these findings are robust to a series of specification checks including the application of a regression discontinuity design based on knowledge of the selection rule overall the preferred estimates suggest that the local benefits of superfund cleanups are small and appear to be substantially lower than the 43 million mean cost of superfund cleanups

dumping and dynamic competition abstract when the current output level affects future production costs domestic and foreign profit maximizing firms may set prices below current costs to gain experience antidumping enforcement which poses a barrier to below cost sales by foreign rivals changes the payoff structure of competition and alters the equilibrium decisions of both foreign and domestic firms a comparison of the nash equilibria with and without antidumping rules shows that these rules change market outcomes even when they do not appear to be binding ex post this positive analysis of antidumping enforcement complements previous studies that have considered the motivation for dumping

demand for environmental goods evidence from voting patterns on california initiatives this article studies voting behavior on 16 environmental ballot propositions in california in order to characterize the demand for environmental goods the environment is found to be a normal good for people with mean incomes but some environmental goods are inferior for those with high incomes at least when supplied collectively an important price of environmental goods is reduced income in the construction farming forestry and manufacturing industries income and price can explain most of the variation in voting there is little need to introduce preference variables such as political ideology

do stationary risk premia explain it all evidence from the term structure abstract predictable variations in excess returns have often been attributed to the presence of time varying risk premia in this paper we use an insight based upon new techniques from time series analysis to test whether stationary risk premia can alone explain the behavior of excess returns to long bonds relative to rolling over short rates surprisingly we reject this hypothesis using u s t bill returns we then show that either permanent shocks to the risk premia and or rationally anticipated shifts in the interest rate process could produce anomalous results

domino dumping i competitive exporters when exporting firms face the prospect of voluntary export restraints they have an incentive to export more than with no prospect of a voluntary export restraint since greater exports lead to larger license allocations in the event of a voluntary export restraint export country governments incentives differ leading either to export tax or subsidy depending on the circumstances the prospect of one departure from free trade thus leads to another a domino effect antidumping enforcement will ordinarily not eliminate and ironically may increase dumping copyright 1992 by american economic association

new estimates of climate demand evidence from location choice abstract we develop and apply to census data a new method for estimating climate demand the method is useful for ranking quality of life based upon a willingness to pay criterion our two major findings are that the willingness to pay quality of life index is correlated with the hedonic approach s ranking but that the migration approach generates much larger estimates of willingness to pay for a more moderate climate this finding is relevant for evaluating the economic impact of global warming

new estimates of quality of life in urban areas implicit markets capture compensation for intraurban and interregional differe nces in amenities and yield differences in housing prices and wages these pecuniary differences become preference based weights in a qual ity of life index hedonic equations are estimated using microdata fr om the 1980 census and assembled county based amenity data on climati c environmental and urban conditions ranking of 253 urban counties reveals substantial variation within as well as among the 185 urba n areas the quality of life differences across counties within one s msa is almost one half of the difference between the top and bottom ranked counties in the nation copyright 1988 by american economic association

income sorting and the demand for clean air evidence from southern california people sort over space due to among other factors the demand for amenities this demand is partially determined by income using data from southern california we investigate how variation in air quality affects residential sorting by income we find that sorting caused by air quality differences may exacerbate income segregation

dumping at less than marginal cost abstract the traditional analysis of dumping in an export market treats the term merely as a synonym for price discrimination in an international context crucially it does not predict that goods will be sold overseas at price less than marginal cost this paper explores the possibility that dumping can occur in the more obvious lay sense of selling at less than marginal cost it suggests three reasons why this may occur in circumstances of uncertainty pursuance of managerial goals and strategic entry deterrence in the first of these the traditional prediction of reduced surplus for domestic consumers is no longer assured

trade and communication costs two models in which communication costs are a cost to trade are investigated one model looks at the role of communication in determining the firms geographic extent in the use of local factor services communication costs are modelled as a quasi public good network in which communication services are provided by an average cost pricing monopolist the network technology is subject to increasing returns congestion effects and network externalities the second model focuses on communication for the purposes of international trade in goods with similar assumptions on the technology of communication as in the first model in this model an important distinction is made between international equilibrium and global equilibrium in both models the impact of reductions in communication costs on the market extent of firms trade volumes and productivity are examined the models have generic multiple equilibria with quite different welfare and comparative static properties

benchmarking the expectations hypothesis of the interest rate term structure an analysis of cointegration vectors i test cointegration restrictions that are consistent with the expectations hypothesis of the term structure by employing the full information maximum likelihood methods developed by johansen yield curves appear to be the result of cointegration among interest rates the cointegration vectors that best describe the long term impact of interest rate levels on interest rate changes can often be written as linear combinations of interest rate spreads there is however difficulty in keeping short term yields in such a restricted cointegrated system with other interest rates short term speculative returns from long term bonds do not conform to the expectations hypothesis

explaining the failures of the term spread models of the rational expectations hypothesis of the term structure contrary to the predictions of the rational expectations hypothesis of the term structure of interest rates empirical evidence suggests that the term spread between long and short rates fails to forecast future movements of long term rates although its forecasts of future short term rates are in the correct direction in this paper the authors show that this puzzling behavior of the term spread alone can be explained by a time varying term premium that is correlated with the term spread once this is accounted for neither expression of the expectations hypothesis is against the predictions of the theory copyright 1997 by ohio state university press

explorations into factors explaining money market returns in this article we measure and interpret the common factors that describe money market returns results are presented for both three and four factor models we find that the three factor model explains on average 86 percent of the total variation in most money market returns while the four factor model explains on average 90 percent of this variation using mimicking portfolios we provide an interpretation of the systematic risks represented by these factors in this article we attempt to measure and interpret the common factors that describe money market returns the factor approach we employ assumes that the covariance matrix of a set of random variables in this case excess returns can be decomposed into common or systematic components and idiosyncratic or nonsystematic components this decomposition into systematic and nonsystematic components is based on an assumption of a linear relationship between the returns of each security and a set of common factors this is the assumption of linear return generating models which form an integral part of the structure of many asset pricing theories for example arbitrage pricing theory apt as developed by ross 1976 the interpretation is that the common factors represent sources of systematic or nondiversifiable risk and the idiosyncratic component of returns represents diversifiable risks our focus here is not on testing a particular asset pricing model per se but on developing empirical evidence for the existence of stylized facts regarding money market returns the stylized facts take the form of the existence measurement and interpretation of the common factors that are found in money markets our attempt to measure and interpret these sources of systematic risk may eventually lead to the construction of observable eco

an empirical analysis of nonstationarity in a panel of interest rates with factors this paper studies nonstationarities in a panel of canadian and us interest rates of different maturities and risk we focus on methods which model the cross sectional dependence within the panel as a linear dynamic factor model and decompose our data into common and idiosyncratic components that we analyze in turn our results suggest the presence of a single nonstationary factor in our panel since some of the idiosyncratic components are stationary we conclude that these series are cointegrated finally the dominant factors can be interpreted as level and slope factors as in the term structure literature copyright 2007 john wiley sons ltd
