optimal nonparametric estimation of first price auctions this paper proposes a general approach and a computationally convenient estimation procedure for the structural analysis of auctioni data considering first price sealed bid auction models within the independent private value paradigm we show that the underlying distribution of bidders private values is identified from observed bids and the number of actual bidders without any parametric assumptions using the theoiy of minimax we establish the best rate of uniform convergence at which the latent density of private values can be estimated nonparametrically from available data we then propose a two step kernel based estimator that converges at the optimal rate

measuring global economic interdependence a hierarchical network approach this paper investigates the business cycle co movement across countries and regions since 1950 as a measure for quantifying the economic interdependence in the ongoing globalisation process our methodological approach is based on analysis of a correlation matrix and the networks it contains such an approach summarises the interaction and interdependence of all elements and it represents a more accurate measure of the global interdependence involved in an economic system our results show 1 the dynamics of interdependence has been driven more by synchronisation in regional growth patterns than by the synchronisation of the world economy and 2 world crisis periods dramatically increase the global co movement in the world economy

secular cost changes and the size of government towards a generalized theory abstract baumol s cost disease account of government growth is contrasted with that of kau and rubin who focus on decreasing costs of tax collection over time the apparent paradox wherein the first theory explains government growth by cost increases and the second by way of cost decreases is technically resolved why both theories seem to be able to stand up to empirical tests even though they use similar data is then explained finally public choice analysis is employed to reveal further potential for the ultimate construction of one all embracing secular cost change theory of government growth

correlation of business cycles in the euro zone in this short article we use a simple diferences in diferences technique to investigate whether bilateral correlation of business cycles increased more amongst members of the european monetary union emu after the implementation of the euro than amidst other oecd economies we present evidence suggesting this to be the case importantly this higher correlations appear to be the result of the common monetary policy per se and not of higher bilateral trade

measuring business cycle comovements in europe evidence from a dynamic factor model with time varying parameters abstract estimation results from a dynamic factor model confirm an increase in output synchronization across european countries during the run up to the inception of emu but emu by itself has not continued to foster the emergence of a common business cycle

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

procurement auctions under quality manipulation corruption abstract in procurement quality manipulation corruption arises when the agent tasked with quality evaluation exaggerates the quality of a corrupt firm if an inefficient firm is favored by the agent the buyer can adjust the procurement mechanism such that the corruption rent of the inefficient firm erodes the technological rent of the efficient firm however doing so may require procuring the project at an undesirable quality level to resolve this trade off between corruption deterrence and quality distortion unlike standard results in the literature the buyer may overstate her preference for quality and the dominance of scoring auctions over minimum quality auctions disappears

procurement contracting with time incentives theory and evidence in public procurement social welfare often depends on how quickly the good is delivered a leading example is highway construction where slow completion inflicts a negative externality on commuters in response highway departments award some contracts using scoring auctions which give contractors explicit incentives for accelerated delivery we characterize efficient design of these mechanisms we then gather an extensive data set of highway projects awarded by the california department of transportation between 2003 and 2008 by comparing otherwise similar contracts we show that where the scoring design was used contracts were completed 30 40 faster and the welfare gains to commuters exceeded the increase in procurement costs using a structural model that endogenizes participation and bidding we estimate that the counterfactual welfare gain from switching all contracts from the standard design to the efficient apb design is nearly 22 of the total contract value 1 14 billion copyright 2011 oxford university press

the design of multidimensional auctions procurement auctions usually require the bid to specify several characteristics of the contract to be fulfilled in this article i study the design of such mechanisms allowing for a special case of correlation of the firm s costs i describe the properties of optimal mechanisms and study the design of multidimensional auctions contrary to the independent costs model to implement the optimal outcome the procurer will need to use a two stage auction in the first stage the procurer selects one firm in the second stage he bargains to readjust the level of quality to be provided

party polarization and the business cycle in the united states a large literature has studied the trend of greaterpolarization between democrats and republicans in congress this paper empirically examines the extent to which inflationand unemployment explain cyclical movements ofpolarization over time an informal application of thestandard downsian spatial competition model of partiesgenerates the following relationships ceteris paribus 1 inflation should be associated with policy convergence 2 unemployment should be associated with polarization 3 theeffect of unemployment on polarization should be larger inmagnitude than the effect of inflation on convergence and 4 the effect of unemployment on polarization should be strongerin the house than in the senate we estimate the relationshipbetween vote records and business cycle conditions over the1947 1999 period using a gls model with varying lags ourresults are broadly consistent with these business cyclehypotheses of polarization though greater support is found inhouse data than in senate data

a study of the internal organization of a bidding cartel this paper examines bidding in over 1 700 knockout auctions used by a bidding cartel or ring of stamp dealers in the 1990s the knockout was conducted using a variant of the model studied by daniel graham robert marshall and jean francois richard 1990 following a reduced form examination of these data damages induced inefficiency and the ring s benefit from colluding are estimated using a structural model in the spirit of emmanuel guerre isabelle perrigne and quang vuong 2000 a notable finding is that nonring bidders suffered damages that were of the same order of magnitude as those of the sellers

an empirical study of an auction with asymmetric information this paper examines federal auctions for drain age leases on the outer continental shelf from 1959 to 1969 these are leases that are adjacent to tracts on which a deposit has been discovered the authors find that the data strongly support the hypotheses that neighbor firms are better informed about the value of a lease than nonneighbor firms that neighbor firms coordinate their bidding decisions and that both types of firms bid strategically in accordance with the bayesian nash equilibrium model for first price sealed bid auctions with asymmetric information

regulating bidder participation in auctions regulating bidder participation in auctions can potentially increase efficiency compared to standard auction formats with free entry we show that the relative performance of two such mechanisms a standard first price auction with free entry and an entry rights auction depends nonmonotonically on the precision of information that bidders have about their costs prior to deciding whether to participate in a mechanism as an empirical application we estimate parameters from first price auctions with free entry for bridge building contracts in oklahoma and texas and predict that an entry rights auction increases efficiency and reduces procurement costs significantly

bidding for incomplete contracts an empirical analysis of adaptation costs abstract procurement contracts are often renegotiated because of changes that are required after their execution using highway paving contracts we show that renegotiation imposes significant adaptation costs reduced form regressions suggest that bidders respond strategically to contractual incompleteness and that adaptation costs are an important determinant of their bids a structural empirical model compares adaptation costs to bidder markups and shows that adaptation costs account for 7 5 14 percent of the winning bid markups from private information and market power the focus of much of the auctions literature are much smaller by comparison implications for government procurement are discussed jel d44 d82 d86 h57 l13 l74 r42

product differentiation and location decisions under demand uncertainty we investigate hotelling s duopoly game of location then price choices with quadratic transportation costs and uniformly distributed consumers under the assumption that firms are uncertain about the exact location of demand we characterize the unique equilibrium and the socially optimal locations contrary to the individual level random utility models location uncertainty is a differentiation force in equilibrium increases in the variance of the uncertainty lead to greater differentiation higher expected equilibrium prices and profits and a greater welfare loss

design competition through multidimensional auctions this article studies design competition in government procurement by developing a model of two dimensional auctions wherefirms bid on both price and quality and bids are evaluated by a scoring rule designed by a buyer three auction schemes first score second score and second preferred offer are introduced and related to actual practices if the buyer can commit to a scoring rule in his best interest the resulting optimal scoring rule underrewards quality relative to the buyer s utility function and implements the optimal outcome for the buyer underfirst and second score auctions absent the commitment power the onlyfeasible scoring rule is the buyer s utility function under which 1 all three schemes yield the same expected utility to the buyer and 2 first and second score auctions induce the first best level of quality which turns out to be excessive from the buyer s point of view

uniqueness of equilibrium in sealed high bid auctions abstract for the case of two buyers we show that equilibrium in the sealed high bid auction is unique when i buyers reservations prices are drawn independently from distributions with finite support and positive mass at the lower endpoint ii buyers have private values and iii buyers preferences are log supermodular for more than two buyers we obtain the same result under the additional assumptions that iv buyers with the same reservation price have the same preferences v buyers are risk neutral or risk averse with non increasing absolute risk aversion and vi the supports of the different buyers distributions of reservation prices have the same upper endpoint

strategic design under uncertain evaluations structural analysis of design build auctions i investigate firms competition over price and product design under uncertain design evaluations in the context of design build db auctions reviewers design evaluations contain uncertainty from a bidder s perspective leading luck to curtail differences in firms chances of winning i model bidders behavior and derive semiparametric identification of the model primitives uncertain evaluations worsen the expected price of design quality and exacerbate an auctioneer s uncertainty in auction outcomes a simple adjustment in the auction mechanism may completely shut down the impact of uncertain evaluations on bidding incentives restoring efficient allocations of projects

international business cycles world region and country specific factors the paper investigates the common dynamic properties of business cycle fluctuations across countries regions and the world we employ a bayesian dynamic latent factor model to estimate common components in macroeconomic aggregates output consumption and investment in a 60 country sample covering seven regions of the world the results indicate that a common world factor is an important source of volatility for aggregates in most countries providing evidence for a world business cycle we find that region specific factors play only a minor role in explaining fluctuations in economic activity we also document similarities and differences across regions countries and aggregates jel f41 e32 c11 c32

structural econometric analysis of descending auctions since vickrey s 1961 paper the theory of auctions has considerably expanded particularly over the last decade see e g milgrom 1985 1986 and mcafee and mcmillan 1987 for recent surveys in contrast except for some experimental work only a few empirical studies have attempted to validate the new theoretical auction models using field auction data two approaches have emerged the first has concentrated upon testing some implications of the theory of auctions using reduced form econometric models with observed bids as the explained variables explanatory variables might then be the reservation price the number of potential bidders when observed and some characteristics of the auctioned object examples are hansen 1985 1986 hendricks et al 1987 and hendricks and porter 1988 the second approach which is structural has a long tradition in econometrics starting from the work of the cowles commission this approach is followed in this paper the basic idea is simple and relies upon

uniqueness of the equilibrium in first price auctions abstract if the value cumulative distribution functions are strictly log concave at the highest lower extremity of their supports a simple geometric argument establishes the uniqueness of the equilibrium of the first price auction in the asymmetric independent private values model

nonparametric identification of risk aversion in first price auctions under exclusion restrictions this paper studies the nonparametric identification of the first price auction model with risk averse bidders within the private value paradigm first we show that the benchmark model is nonindentified from observed bids we also derive the restrictions imposed by the model on observables and show that these restrictions are weak second we establish the nonparametric identification of the bidders utility function under exclusion restrictions our primary exclusion restriction takes the form of an exogenous bidders participation leading to a latent distribution of private values that is independent of the number of bidders the key idea is to exploit the property that the bid distribution varies with the number of bidders while the private value distribution does not we then extend these results to endogenous bidders participation when the exclusion restriction takes the form of instruments that do not affect the bidders private value distribution though derived for a benchmark model our results extend to more general cases such as a binding reserve price affiliated private values and asymmetric bidders last possible estimation methods are proposed

an empirical study of scoring auctions and quality manipulation corruption abstract we provide a modeling framework for empirical studies of scoring auction data that addresses the problem that scores are intangible and cannot be compared across auctions we apply the method on a dataset from chinese server room procurement auctions and provide empirical evidence for the seminal scoring auction model developed by che 1993 and asker and cantillon 2008 using this method we study the problem of quality manipulation the quality evaluating agent may exaggerate the quality score of a favored firm in exchange for a bribe we propose a test for quality manipulation and perform it on the server room procurement dataset we find that the bidding behaviors are generally consistent with the competitive model but not the corruption model

how does globalization affect the synchronization of business cycles this paper examines the impact of rising trade and financial integration on international business cycle comovement among a large group of industrial and developing countries the results provide at best limited support for the conventional wisdom that globalization has increased the degree of synchronization of business cycles the evidence that trade and financial integration enhance global spillovers of macroeconomic fluctuations is mostly limited to industrial countries one striking result is that on average cross country consumption correlations have not increased in the 1990s precisely when financial integration would have been expected to result in better risk sharing opportunities especially for developing countries this abstract was borrowed from another version of this item

procurement when price and quality matter a buyer seeks to procure a good characterized by its price and its quality from suppliers who have private information about their cost structure xed cost and marginal cost of providing quality we characterize the buyer s optimal buying mechanism we then use the optimal mechanism as a theoretical and numerical benchmark to study simpler buying procedures such as scoring auctions and bargaining scoring auctions can extract a signifi cant proportion of the buyer s strategic surplus the difference between the expected utility from the optimal mechanism and the e cient auction bargaining does less well and often does worse than the e cient auction

the size of government most research on the causes of growth in government expenditure has focused on the demand for government services in this paper we argue that in fact this growth may have occurred because of changes in supply changes in technology leading to increased specialization and thus increased opportunity costs of self production have led to increased market production and increased record keeping also female labor force participation has increased both of these factors serve to reduce the efficiency cost of collecting taxes if the demand for government spending has not changed this increase in supply would lead to a larger public sector we estimate a system of simultaneous equations for the period 1929 1970 incorporating this hypothesis and the results are consistent with the theory we are able to explain virtually all of the growth of government increases in female labor force participation seems to be a very important variable in this explanation

semiparametric estimation of first price auctions with risk averse bidders in view of the non identification of the first price auction model with risk averse bidders this paper proposes some parametric identifying restrictions and a semiparametric estimator for the risk aversion parameter s and the latent distribution of private values specifically we exploit heterogeneity across auctioned objects to establish semiparametric identification under a conditional quantile restriction of the bidders private value distribution and a parameterization of the bidders utility function we develop a multistep semiparametric method and we show that our semiparametric estimator of the utility function parameter s converges at the optimal rate which is slower than the parametric one but independent of the dimension of the exogenous variables thereby avoiding the curse of dimensionality we then consider various extensions including a binding reserve price affiliation among private values and asymmetric bidders the method is illustrated on u s forest service timber sales and bidders risk neutrality is rejected

identification and estimation of auction models with unobserved heterogeneity in many procurement auctions the bidders unobserved costs depend both on a common shock and on idiosyncratic private information assuming a multiplicative structure i derive sufficient conditions under which the model is identified and propose a non parametric estimation procedure that results in uniformly consistent estimators of the cost components distributions the estimation procedure is applied to data from michigan highway procurement auctions private information is estimated to account for 34 of the variation in bidders costs it is shown that accounting for unobserved auction heterogeneity has important implications for the evaluation of the distribution of rents efficiency and optimal auction design

increasing competition and the winner s curse evidence from procurement we assess empirically the effects of the winner s curse which in common value auctions counsels more conservative bidding as the number of competitors increases first we construct an econometric model of an auction in which bidders preferences have both common and private value components and propose a new monotone quantile approach which facilitates estimation of this model second we estimate the model using bids from procurement auctions held by the state of new jersey for a large subset of these auctions we find that median procurement costs rise as competition intensifies in this setting then asymmetric information overturns the common economic wisdom that more competition is always desirable

first price auctions in the asymmetric n bidder case i consider the first price auction when the bidders valuations may be differently distributed i show that every bayesian equilibrium is an essentially pure equilibrium formed by bid functions whose inverses are solutions of a system of differential equations with boundary conditions i then prove the existence of an equilibrium i prove its uniqueness when the valuation distributions have a mass point at the lower extremity of the support i give sufficient conditions for uniqueness when every valuation distribution is one of two atomless distributions i establish inequalities between equilibrium strategies when relations of stochastic dominance exist between valuation distributions

an output gap measure for the euro area exploiting country level and cross sectional data heterogeneity abstract this paper proposes a methodology to estimate the euro area output gap by taking advantage of two types of data heterogeneity on the one hand the method uses information on real gdp inflation and the unemployment rate for each member state on the other hand it jointly considers this information for all the euro area countries to extract an area wide output gap measure the setup is an unobserved components model that theorizes common output trend and cyclical components across euro area economies in addition to country specific counterparts i estimate the model with bayesian methods using data for the 19 countries of the euro area from 2000 q1 through 2018 q3 and perform model comparisons across different specifications of the output trend the estimation of the model preferred by the data indicates that because of negative shocks to trend output during the global financial crisis output was only slightly below potential in that period but an output gap of about negative 3 emerged during the european debt crisis at the end of the sample period output is estimated to be 3 5 above potential output which is growing at an average annual pace of only 0 5 in recent years

trending economic factors and the structure of congress in the growth of government 1930 2002 we investigate the role of congress in the growth of federal public expenditure since 1930 building on the work of kau and rubin public choice 113 389 402 2002 the model incorporates majority party strength and the extent of party control of congress in addition to the median ideological position of elected representatives we first provide estimates of the relative importance of the state of congress and of trending supply and demand side economic factors in the evolution of federal spending the resulting models are then used to simulate the consequences of the radical and historically unprecedented shift to the right of congress in 1994 95

precautionary bidding in auctions we analyze bidding behavior in auctions when risk averse buyers bid for a good whose value is risky we show that when the risk in the valuations increases dara bidders will reduce their bids by more than the appropriate increase in the risk premium ceteris paribus buyers will be better off bidding for a more risky object in first price second price and english auctions with affiliated common interdependent values this precautionary bidding effect arises because the expected marginal utility of income increases with risk so buyers are reluctant to bid so highly we also show that precautionary bidding behavior can make dara bidders prefer bidding in a common values setting to bidding in a private values one when risk neutral or cara bidders would be indifferent thus the potential for a winner s curse can be a blessing for rational dara bidders
