explaining business cycles in small open economies abstract this paper analyzes the role of world price shocks fluctuations in the prices of capital intermediate and primary goods and in the world real interest rate in the generation and propagation of business cycles in small open developing countries i construct a stochastic dynamic multi sector small open economy model the model is a variant of the specific factors model and reflects the major structural characteristics of developing economies i utilize variance decomposition methods to quantitatively evaluate the impact of world price shocks the results indicate that world price shocks account for a significant fraction of business cycle variability in developing countries

debt dynamics in europe a network general equilibrium gvar approach in this work we investigate the dynamic interdependencies among the eu12 economies using a competitive general equilibrium network system representation additionally using bayesian techniques we estimate the autoregressive scheme that characterizes the equilibrium price system of the network while characterizing each economy node in the universe of our network in terms of its degree of pervasiveness in this context we unveil the dominant s unit s in our model and estimate the dynamic linkages between the economies nodes lastly in terms of robustness analysis we compare the findings of the degree pervasiveness of each economy against other popular quantitative methods in the literature according to our findings the economy of germany acts as weakly dominant entity in the eu12 economy meanwhile all shocks die out in the short run without any long lasting effect

the real effects of financial integration abstract this paper shows how correlations in gdp fluctuations rise with financial integration finance serves to increase international correlations in both consumption and gdp fluctuations which explains the persistent gap between the two in the data a quantity puzzle the positive association between financial integration and gdp correlation constitutes a puzzle as theory suggests a negative relation if anything nevertheless it prevails in the data even after the effects of finance on trade and specialization are accounted for

the role of multilateral institutions in international trade cooperation the world trade organization wfo lacks the power to directly enforce agreements it is therefore important to understand what role the wto can play to facilitate international cooperation and whether a multilateral institution can offer distinct advantages over a web of bilateral agreements this paper examines two potential benefits of a multilateral trade institution first verifying violations of the agreements and informing third parties thus facilitating multilateral reputation mechanisms second promoting multilateral trade negotiations rather than a web of bilateral negotiations the model suggests that a multilateral approach is particularly important when there are strong imbalances in bilateral trading relationships

tariff retaliation versus financial compensation in the enforcement of international trade agreements the authors analyze whether financial compensation is preferable to the current system of dispute settlement in the world trade organization that permits member countries to impose retaliatory tariffs in response to trade violations committed by other members they show that monetary fines are more efficient than tariffs in terms of granting compensation to injured parties when there are violations in equilibrium however fines suffer from an enforcement problem since they must be paid by the violating country if fines must ultimately be supported by the threat of retaliatory tariffs they fail to yield a more cooperative outcome than the current system the authors also consider the use of bonds as a means of settling disputes if bonds can be posted with a third party they do not have to be supported by retaliatory tariffs and can improve the negotiating position of countries that are too small to threaten tariff retaliation

cotton subsidies the wto and the cotton problem wto and the cotton problem following an 8 year long dispute over cotton subsidies brazil and the united states signed a memorandum of understanding on april 21 2010 effectively paving the way for settling the dispute this paperargues that cotton subsidies are just the tip of the iceberg while a number of other perhaps more important issues require attention and indeed political will chief among them is the persistent divergence between cotton prices and the prices of other agricultural commodities which reflects for the most part the large supply response by china and india a direct consequence of con version to biotech cotton varieties in these and other countries such response which kept cotton prices low compared with other commodities imposes a competitive disadvantage to non users of biotech cotton the paper also highlights two additional constraints faced by the cotton producing countries of west and central africa namely the structural inefficiencies of their primary processing industries also known as ginning and the appreciation of the cfa franc against the us dollar without downplaying the importance of subsidy elimination the paper concludes that these impediments should receive high priority in the policy agenda

repeated auctions with impatient bidders and externalities author affiliation ki eun rhee krhee kdischool ac kr acknowledgment i am grateful to kyle bagwell for providing invaluable advice and support throughout the research process i also thank michael riordan eiichi miyagawa and two anonymous referees for helpful comments 1 introductioncollusive bidding behavior has been conventionally studied in a static setup often relying on some unspecified repeated interaction story for the enforcement of a cartel 1 it is not clear however whether the results from static auctions immediately carry over to a repeated setup when bidders are impatient and the enforcement or the participation constraint is binding moreover many empirical analyses for detecting collusion rely on an explicitly repeated structure rendering a theoretical analysis of collusion in a repeated setup necessary 2 several recent theoretical developments in repeated auctions have been made by aoyagi 2003 2007 skrzypacz and hopenhayn 2004 and blume and heidhues 2006 taking standard auctions as stage games these articles present various collusive bidding schemes with asymmetric punishments that outperform the bid rotation scheme which is known to be optimal in static auctions mcafee and mcmillan 1992 this article studies collusive bidding behavior in repeated auctions among both patient and impatient bidders when the outside option of the participation constraint is endogenized because of externalities a stage game involves negative externalities among the bidders when any losing bidder is worse off if a rival wins the good than if no one wins it auctions with externalities have been introduced most notably by jehiel and moldovanu 1996 and jehiel moldovanu and stacchetti 1996 these auctions describe environments in which the outcomes of auctions affect the nature of ensuing market interactions among potential bidders a wide variety of situations in which bidders are a set of oligopoly firms competing in the same market apply to this setting for example procurement auctions for highway construction contracts studied empirically by porter and zona 1993 may qualify as repeated independent private value auctions with negative externalities except that the lowest bidder wins 3 consecutive highway lettings were distributed by the department of transportation dot to a set of oligopoly firms competing in the same industry negative externalities may arise because a firm that wins the auction may experience learning by doing which provides the winning firm with a comparative cost advantage or because the winning firm may gain a reputation that gives the firm an advantage in future private sector competition as jehiel and moldovanu 1996 and jehiel moldovanu and stacchetti 1996 discuss the issue of participation is nontrivial in auctions with externalities because the ex ante payoff a bidder expects by not participating is no longer zero as in standard auctions but is rather endogenously determined by the actions of the other bidders thus an analysis of collusive bidding behavior under both nonbinding and binding participation constraints seems especially worth studying for these auctions the main findings of this article are that i there are no bidding wars along the equilibrium path and bidders expect to receive the maximal continuation values when they are both patient and impatient when bidders are impatient the optimal collusive bidding scheme involves ii a lower threshold type above whom bidding starts when externalities are small or iii more frequent jumps i e more sorting of bidders types when externalities are large in both cases seller s ex ante profit is higher when bidders are impatient if we consider patient bidders to be the ones that are interacting in a stable market 4 results carry an empirical implication either less frequent sales or fewer bid levels in auctions that are let out in stable markets will be observed

trade finance specialization and synchronization i investigate the determinants of business cycle synchronization across regions the linkages between trade in goods financial openness specialization and business cycle synchronization are evaluated in the context of a system of simultaneous equations the main results are as follows i specialization patterns have a sizable effect on business cycles most of this effect is independent of trade or financial policy but directly reflects differences in gdp per capita ii a variety of measures of financial integration suggest that economic regions with strong financial links are significantly more synchronized even though they also tend to be more specialized iii the estimated role of trade is closer to that implied by existing models once intra industry trade is held constant the results obtain in a variety of data sets measurement strategies and specifications they relate to a recent strand of international business cycle models with incomplete markets and transport costs and on the empir

congestion function specification and the publicness of local public goods abstract this paper is about the measurement of congestion within the median voter demand framework the model of congestion traditionally used in the literature and four others are compared and tested in a median voter framework the results show that a more flexible functional form which imposes fewer a priori restrictions on the data does at least as good a job of explaining variations in local government expenditures furthermore it is shown that measured publicness of local public goods depends entirely on the a priori restrictions imposed on the congestion function

developing countries as plaintiffs and defendants in gatt wto trade disputes developing countries have been increasing their participation in the formal institutions and proceedings of the multilateral trading system a prominent example is their more frequent involvement as defendants and plaintiffs in gatt wto trade disputes this paper provides an initial economic appraisal of developing country performance in the gatt wto dispute settlement system we measure the economic resolution of these disputes through trade liberalisation gains and our results suggest that developing country plaintiffs have had more success under wto disputes than was the case under the gatt we also document evidence on potential determinants of this success the capacity for plaintiffs to make credible retaliatory threats and the guilty determinations by gatt wto panels finally there is also some evidence that developing countries have recognised the importance of retaliatory threats and have responded by changing their pattern of dispute initiation under the wto to better take advantage of the instances in which they have sufficient leverage to threaten retaliation and induce compliance with gatt wto obligations

transmission of business cycle shocks between the us and the euro area we analyse the transmission of structural shocks between the us and the euro area within a two country vector autoregressive var framework for that purpose we simultaneously identify cost push demand and monetary policy shocks for both countries using sign restrictions our results show that domestic shocks explain the largest share of the forecast error variances for gross domestic product gdp consumer prices and interest rate in both countries in the short run whilst spillovers from the other country and global factors gain importance in the medium run the strength of the shock transmission between the two countries is quite symmetric our approach to the identification of structural shocks allows us to construct confidence bands that account both for estimation and identification uncertainty we find impulse responses to domestic shocks to be significant while spillovers across countries are insignificant

public sector debt dynamics the persistence and sources of shocks to debt in 10 eu countries this paper characterises the time series properties of debt gdp ratios in ten eu countries over the period 1982 2009 it establishes that shocks to debt ratios persist and measures the size and source of the permanent effects of shocks as they evolve over time the analysis shows that debt dynamics in the eu10 are complicated involving important inter country interactions and protracted adjustment periods of the order of ten years we find evidence of asymmetries in the effects of different forms of fiscal consolidation with unanticipated reductions in government spending having a more permanent effect than unanticipated increases in government revenue unanticipated business cycle fluctuations also have important long term effects on the ratio

trade deflection and trade depression this is the first paper to empirically examine whether a country s use of an import restricting trade policy distorts a foreign country s exports to third markets we first develop a theoretical model of worldwide trade in which the imposition of antidumping and safeguard taris or trade remedies by one country causes significant distortions in world trade flows we then empirically test this model by investigating the eect of the united states use of such import restrictions on japanese exports of roughly 4800 products into 37 countries between 1992 and 2001 our estimation yields evidence that us restrictions both deflect and depress japanese export flows to third countries imposition of a us antidumping measure against japan deflects trade as the average antidumping duty on japanese exports leads to a 5 7 increase in japanese exports of the same product to the average third country market the imposition of a us antidumping measure against a third country depresses trade as the average us duty imposed on a third country leads to a 5 19 decrease in japanese exports of that same product to the average third country s market we also document the substantial variation in trade deflection and trade depression across dierent importing countries and exported products

partial pooling at the reserve price in auctions with resale opportunities abstract two features common to many auctions are the use of reserve prices and the existence of secondary markets for the goods being sold even in simple symmetric settings the combination of these features can preclude existence of an equilibrium in symmetric separating bidding strategies with a reserve price sufficiently far below the maximum endogenous valuation a symmetric equilibrium still exists but with some types pooling at the reserve the optimal reserve price depends not only on the joint distribution of bidders information before and after the auction but also on how surplus is divided in the secondary market journal of economic literature classification numbers d44 c7 l1 d82

let s get real a factor analytical approach to disaggregated business cycle dynamics this paper develops a method for analysing the dynamics of large cross sections based on a factor analytic model we use law of large numbers arguments to show that the number of common factors can be determined by a principal components method the economy wide shocks can be identified by means of simple structural var techniques and that the parameters of the unobserved factor model can be estimated consistently by applying ols equation by equation we distinguish between a technological and a non technological shock identification is obtained by minimizing the negative realizations of the technology shock empirical results on 4 digit industrial output and productivity for the u s economy from 1958 to 1986 show that 1 at least two economy wide shocks both having a long run effect on sectoral output are needed to explain the common dynamics 2 although the technological shock accounts for at least 50 of the aggregate dynamics of output it cannot by itself explain dynamics at business cycle frequencies 3 sector specific shocks explain the main bulk of total variance but generate mainly high frequency dynamics 4 both the technological and the non technological component of output show a peak for positive sectoral comovements of output at business cycle frequencies 5 technological shocks are strongly correlated with the growth rates of the investment in machinery and equipment sectors and their inputs many interesting questions about cyclical fluctuations and economic growth can be answered only by studying the dynamic behaviour of sectoral variables when data contain information on time for a large cross section of sectors traditional econometric techniques used in the macroeconomic literature such as vector autoregressive var and vector autoregressive moving average varma models are not appropriate since they require the estimation of too many parameters this is why new methods which allow for the reduction of the parameter space need to be developed the objective of this paper is both methodological and descriptive at the methodological level we develop a simple framework for the dynamic analysis of large cross sections the basic model is a dynamic factor analytic model as in sargent and sims 1977 the sectoral variables are decomposed into two unobservable components a common component driven by macroeconomic shocks and a purely sectoral component when

sources of international business fluctuations country specific shocks or worldwide shocks abstract this paper identifies sources of business fluctuations in a two country open economy model with the structural var method focusing on the relative importance of worldwide shocks and country specific shocks unlike previous studies which define country specific shocks as labor supply shocks this study explicitly identifies three kinds of permanent shocks worldwide shocks domestic country specific shocks and foreign country specific shocks with identifying restrictions derived from a theoretical model the main finding is that u s country specific shocks are the most important in explaining u s and foreign output fluctuations except in the short run

business cycles for g7 and european countries this article proposes classical business cycle turning points for the g7 and a number of european countries based on industrial production this enables the authors to examine the international nature of cyclical movements free from arbitrary assumptions about the trend in particular they show that cyclical assymetry is common with slopes during declines being generally larger in magnitude than during expansions a binary measure of association for expansion and contradiction regimes indicates a core group of european countries related to each other and apparently linked to the united states and japan through germany copyright 1997 by university of chicago press

auctioning countermeasures in the wto we offer a first formal analysis of auctioning retaliation rights within the wto we show that the auctions exhibit externalities among bidders and we characterize equilibrium bidder behavior under alternative auction formats if the violating country is prevented from bidding to retire the right of retaliation against it then the possibility of auction failure arises whereby no bids are made despite positive valuation by bidders if the violating country is instead permitted to bid then auction failure is precluded and indeed the right of retaliation is always retired we evaluate these different auction formats from normative revenue compliance efficiency standpoints

trade of permits for greenhouse gas emissions bilateral trade need not be the answer the kyoto protocol sets national quotas on ghg emissions and allows international trade of these quotas taking terms of trade effects into account we argue that this trade is characterized by asymmetric identity dependent externalities and show that bilateral trade of permits may not be sufficient for an efficient allocation of emissions we derive conditions under which bilateral trade does improve the allocation of permits the conditions are strong in this sense we argue that for emissions permits market design matters

a note on the publicness of local goods evidence from new york state municipalities for more than a decade now the non publicness of goods provided by local governments has been an accepted result in the median voter demand literature mcmillan wilson and arthur 1981 found that publicness was exhausted in ontario towns of more than 10 000 inhabitants but that there were still unexploited economies to collective provision in smaller towns using the original bergstrom and goodman 1973 model and new york state data i find that there is even less evidence of publicness in small towns than in large ones my results call into question the mcmillan wilson and arthur hypothesis une note sur le degre de materialite publique d usage des biens locaux le cas des municipalites de b etat de new york depuis plus d une decennie l un des resultats de la litterature specialisee analysant le comportement de demande du voteur median a ete que les biens fournis par les gouvernements locaux n etaient pas des biens publics mcmillan wilson et arthur 1981 ont montre que le degre de materialite publique d usage etait limite dans le cas des villes de plus de 10 000 habitants en ontario mais qu il existait des economies inexploitees emanant de la fourniture publique dans le cas des plus petites villes a partir du modele de bergstrom et goodman 1973 et de donnees pour l etat de new york l auteur en arrive a la conclusion qu il y a encore moins de materialite publique d usage dans les petites villes que dans les grandes ces resultats remettent en question l hypothese mcmillan wilson et arthur in contrast to the strict samuelsonian dichotomy of pure public and pure private goods the tiebout 1956 and buchanan 1965 models plot goods along a continuum of congestability goods provided by local governments or collectively purveyed and consumed in clubs are described as lying somewhere between the two polar cases the median voter demand model as developed by borcherding and deacon i would like to thank wallace oates william oakland suk kang and an anonymous referee for helpful comments on earlier drafts of this paper they are of course exonerated from association with such errors as may still remain canadian journal of economics revue canadienne d economique xix no 3 august aout 1986 printed in canada imprime au canada 0008 4085 86 568 573 1 50 canadian economics association this content downloaded from 157 55 39 102 on mon 03 oct 2016 05 08 06 utc all use subject to http about jstor org terms publicness of local goods 569 1972 and bergstrom and goodman 1973 incorporates this hypothesis observed levels of local public expenditures are said to reflect the preference of the median voter however the empirical models also include a congestion function intended to reflect the effect of collective consumption on individual enjoyment the function used in the literature is of the form

does high public debt consistently stifle economic growth a critique of reinhart and rogoff we replicate reinhart and rogoff 2010a and 2010b and find that selective exclusion of available data coding errors and inappropriate weighting of summary statistics lead to serious miscalculations that inaccurately represent the relationship between public debt and gdp growth among 20 advanced economies over 1946 2009 countries with public debt gdp ratios above 90 averaged 2 2 real annual gdp growth not 0 1 as published the published results for i median gdp growth rates for the 1946 2009 period and ii mean and median gdp growth figures over 1790 2009 are all distorted by similar methodological errors although the magnitudes of the distortions are somewhat smaller than with the mean figures for 1946 2009 contrary to reinhart and rogoff s broader contentions both mean and median gdp growth when public debt levels exceed 90 of gdp are not dramatically different from when the public debt gdp ratios are lower the relationship between public debt and gdp growth varies significantly by period and country our overall evidence refutes rr s claim that public debt gdp ratios above 90 consistently reduce a country s gdp growth

urban safety in vancouver allocation and production of a congestible public good this paper is a simultaneous exploration of the within city production of safety with the endogenous allocation of public inputs police three issues are central one is an examination of the local government allocation function second is that safety is specified as a congestible public service consistent with club theory finally the model is estimated using a survey measure of crime these innovations are due to a unique data set containing observations by neighborhoods in the city of vancouver the results are crucial for illustrating crime deterrence as well as the local public good nature of safety

forecasting with medium and large bayesian vars this paper is motivated by the recent interest in the use of bayesian vars for forecasting even in cases where the number of dependent variables is large in such cases factor methods have been traditionally used but recent work using a particular prior suggests that bayesian var methods can forecast better in this paper we consider a range of alternative priors which have been used with small vars discuss the issues which arise when they are used with medium and large vars and examine their forecast performance using a us macroeconomic dataset containing 168 variables we find that bayesian vars do tend to forecast better than factor methods and provide an extensive comparison of the strengths and weaknesses of various approaches typically we find that the simple minnesota prior forecasts well in medium and large vars which makes this prior attractive relative to computationally more demanding alternatives our empirical results show the importance of using forecast metrics based on the entire predictive density instead of relying solely on those based on point forecasts

the role of international factors in the business cycle a multi country study abstract empirical research has been conducted on the various theories of the business cycle over many countries however very little research has attempted to undertake a multi country disaggregate investigation into the sources of output change this paper decomposes fluctuations in industry output in a particular country into 1 a nation specific shock 2 an industry specific shock 3 a common shock and 4 an idiosyncratic factor using a dynamic factor analysis state space approach the paper finds that the industry specific impulse explains a significant but small part of the variance of the forecast error this provides limited support for the disaggregated real business cycle paradigm

size inequality coordination externalities and international trade agreements abstract developing countries now account for a significant fraction of world trade and two thirds of the membership of the world trade organization wto however many are still individually small and thus have a limited ability to bilaterally extract and enforce trade concessions from larger developed economies even though as a group they would be able to do so we show that this coordination externality generates asymmetric outcomes under agreements that rely on bilateral threats of trade retaliation such as the wto but not under agreements extended to include certain financial instruments in particular we find that an extended agreement generates improvements in global efficiency and equity if it includes the exchange of bonds prior to trading but not if it relies solely on ex post fines moreover a combination of bonds and fines generates similar improvements even if small countries are subject to financial constraints that prevent them from posting bonds

multilateral tariff cooperation during the formation of customs unions abstract we study the implications of customs union formation for multilateral tariff cooperation we model cooperation in multilateral trade policy as self enforcing in that it involves balancing the current gains from deviating unilaterally from an agreed upon trade policy against the future losses from forfeiting the benefits of multilateral cooperation that such a unilateral defection would imply the early stages of the process of customs union formation are shown to alter this dynamic incentive constraint in a way that leads to a temporary honeymoon for liberal multilateral trade policies we find however that the harmony between customs unions and multilateral liberalization is temporary eventually as the full impact of the emerging customs union becomes felt a less favorable balance between current and future conditions re emerges and the liberal multilateral policies of the honeymoon phase cannot be sustained

on the economic success of gatt wto dispute settlement what features of the dispute settlement process help governments live up to their trade liberalization commitments exploiting data on gatt wto trade disputes initiated and completed between 1973 and 1998 this paper identifies economic and institutional determinants that help defendant governments commit to liberalizing trade we find substantial evidence consistent with the theory that power measures including threat of retaliation by the plaintiff yield credibility to allow defendant governments to live up to their commitments we find only limited evidence however that particular procedural or institutional features beyond the basic gatt wto dispute settlement forum itself contributed to the successful economic resolution of trade disputes

the publicness of local public goods evidence from ontario municipalities recent studies of local public good provision report publicness parameter estimates of about one indicating private good characteristics this empirical investigation of a wider range of communities obtains parameter estimates of significantly less than one indicating a high degree of publicness exists in smaller municipalities and within the service areas of individual public facilities comprising the supply network in larger centres it is argued that the observed values of the publicness parameters have no normative significance as to the merits of public versus private provision la materialite publique d usage des biens publics locaux resultats d une etude de municipalites ontariennes les etudes recentes sur l approvisionnement de biens publics locaux indiquent des coefficients de materialite publique d usage autour de l unite c est a dire que les biens publics locaux ont de fortes caracteristiques semblables aux biens prives ce memoire presente les resultats d un enquete empirique d un large eventail de communaut6s locales et en arrive a des valeurs pour le coefficient de materialite publique d usage qui sont bien moins que l unite et qui donc indiquent un haut degre de materialite publique d usage dans les petites municipalites mais aussi dans les zones de service d infrastructures particulieres parc bibliotheque poste de pompier etc qui forment le reseau d approvisionnement de biens publics dans les grands centres les auteurs suggerent que les valeurs observees de ces coefficients de materialite publique d usage n ont aucune portee normative et donc ne sauraient arbitrer les merites relatifs d un approvisionnement prive ou public de certains biens

collusion and the choice of auction auctions are used in many different markets including the leasing of a substantial fraction of the natural resources in the united states the procedures used in the auctions conducted by the federal government have been a continuing source of controversy one of the concerns has been the possibility of collusion among bidders this article shows that cartels are stable if the seller uses open ascending bid oral auctions but not if he uses sealed high bid auctions this may help to explain the frequent use of sealed high bid auctions

standard auctions with identity dependent externalities i analyze equilibrium bidding behavior in the open ascending bid auction with identity dependent externalities with reciprocal externalities the allocation is determined by bidders consumption values alone with large nonreciprocal externalities the open auction generates higher expected revenue compared to standard sealed bid auctions the progress of the open auction reveals more information about the identity of the potential winner allowing active bidders greater opportunity to avoid incurring payoff reducing externalities the associated option value to staying active up until a relatively high price translates into higher expected revenue multiple bidders may sequentially quit at the same price and relative to sealed bid auctions bidders experience less ex post regret

probabilistic forecasting of output growth inflation and the balance of trade in a gvar framework summary we apply a global vector autoregressive gvar model to the analysis of inflation output growth and global imbalances among a group of 33 countries 26 regions we account for structural instability by use of country specific intercept shifts the timings of which are identified taking into account both statistical evidence and our knowledge of historic economic conditions and events using this model we compute both central forecasts and scenario based probabilistic forecasts for a range of events of interest including the sign and trajectory of the balance of trade the achievement of a short term inflation target and the incidence of recession and slow growth the forecasting performance of the gvar model in relation to the ongoing financial crisis is quite remarkable it correctly identifies a pronounced and widespread economic contraction accompanied by a marked shift in the net trade balance of the eurozone and japan moreover this promising out of sample forecasting performance is substantiated by a raft of statistical tests which indicate that the predictive accuracy of the gvar model is broadly comparable to that of standard benchmark models over short horizons and superior over longer horizons hence we conclude that gvar models may be a useful forecasting tool for institutions operating at both the national and supra national levels copyright 2010 john wiley sons ltd

sources and propagation of international output cycles common shocks or transmission abstract this paper studies the generation and transmission of international cycles in a multi country model with production and consumption interdependencies two sources of disturbance are considered and three channels of propagation are compared technology disturbances which are mildly correlated across countries are more successful than government expenditure disturbances in reproducing actual data the presence of a common component to the shocks and of production interdependencies appear to be crucial in quantitatively matching the properties of the data

on measuring congestion of local public goods abstract using data for fire protection services this brief paper provides empirical evidence in large part demonstrating the existence of the zoo effect identified by oates the zoo effect implies an upward bias in the measurement of congestion in local public good provision resulting from the lack of a range or quality of service measure the introduction of a quality measure is found to reduce estimates of the degree of congestion in fire protection services

real business cycles in this paper we demonstrate how certain very ordinary economic principles lead maximizing individuals to choose consumption production plans that display many of the characteristics commonly associated with business cycles our explanation is entirely consistent with i rational expectations ii complete current information iii stable preferences iv no technological change v no long lived commodities vi no frictions or adjustment costs vii no government viii no money and ix no serial dependence in the stochastic elements of the environment we also provide a completely worked out example of the type of artificial economy we have in mind the time series properties of the example exhibit some major features of observed business cycles although this type of model may not be capable of explaining all of the regularities in actual business cycles we believe that it provides a useful well defined benchmark for assessing the relative importance of factors e g monetary disturbances

international migration self selection and the distribution of wages evidence from mexico and the united states we use the 1990 and 2000 mexican and u s population censuses to test borjas s negative selection hypothesis that the less skilled are those most likely to migrate from countries with high skill premia earnings inequality to countries with low skill premia earnings inequality we find that mexican immigrants in the united states are more educated than nonmigrants in mexico and were mexican immigrants to be paid according to current skill prices in mexico they would be concentrated in the middle of mexico s wage distribution these results are inconsistent with the negative selection hypothesis and instead suggest that there is intermediate selection of immigrants from mexico

a specification test for choosing the right public good price this article compares statistically three popular public good price definitions the bias of parameter estimates under the wrong definition is derived and calculated one definition is found to be clearly inferior whereas bias estimates indicate little difference between the two remaining definitions public good demand elasticities and their variances are calculated to demonstrate the importance of choosing the right price definition
