frontiers of real time data analysis in the past ten years researchers have explored the impact of data revisions in many different contexts researchers have examined the properties of data revisions how structural modeling is affected by data revisions how data revisions affect forecasting the impact of data revisions on monetary policy analysis and the use of real time data in current analysis this paper summarizes many of the questions for which real time data analysis has provided answers in addition researchers and institutions have developed better real time data sets around the world still additional research is needed in key areas and research to date has uncovered even more fruitful areas worth exploring jel c52 c53 c80 e01

productivity differences across employers the roles of employer size age and human capital recent research using longitudinal microeconomic databases on businesses and individuals has uncovered tremendous heterogeneity across businesses even within narrowly defined industrial sectors we observe large differences in the levels and growth rates of inputs outputs and productivity across workers even controlling for demographic characteristics wage and employment outcomes vary a great deal and there are sizable worker flows across jobs in the economy these worker flows are closely connected to firm outcomes reflecting in large part the ongoing shift in resources from less productive to more productive employers the primary message is that the continual process of matching and sorting as businesses and workers seek their niches is heterogeneous with experimentation learning and selection all playing important roles understanding the connection between the matching and sorting of businesses and workers is at the very heart of the overlap between industrial organization and labor economics however due to the paucity of data linking businesses and workers at the micro level we know relatively little about these interactions although a large empirical literature suggests that worker outcomes are associated with firm characteristics notable examples are firm size wage effects compensating wage differentials and interindustry wage differentials very little is known about the converse the process by which business outcomes are associated with the characteristics of their employees there are a number of questions associated with this process do employers choose different modes of production resulting in skill segregation as suggested by the sorting and assignment hypotheses in michael kremer 1993 and michael sattinger 1993 or do all firms in a given industry select roughly the same workforce composition how do employers change their workforce composition either to accommodate demand shocks or to experiment with new modes of production in turn what is the connection between these different decisions regarding workforce composition and observable business outcomes such as survival growth and productivity in this short paper our empirical objectives are relatively modest compared to these broad research questions our focus is to provide an initial investigation into the connection between a key measure of firm performance labor productivity and the composition of the firm s workforce as measured by observable worker characteristics we exploit longitudinal matched employeremployee micro data developed under a recent pilot project at the u s census bureau our data set contains longitudinal information on key outcomes of the businesses as well as many of the basic demographic characteristics for the universe of workers at these businesses although longitudinal matched employer employee micro data have been developed in a variety of countries over the last decade or so see john abowd and francis kramarz 1999 ours is the first large scale micro level data set in the united states that allows the investigation haltiwanger department of economics university of maryland college park md 20742 u s bureau of the census and nber lane department of economics american university washington dc 20016 and u s bureau of the census spletzer bureau of labor statistics 2 massachusetts ave n e washington dc 20212 we thank adela luque and javier miranda for superb research assistance and charles brown and marilyn manser for comments on an earlier draft this research was conducted at the center for economic studies at the u s bureau of the census while the second author was an american statistical association census bureau fellow the analysis and results are attributable to the authors and do not necessarily reflect concurrence of the institutions they represent

corporate income tax competition double taxation treaties and foreign direct investment abstract in the presence of international capital mobility foreign direct investment is influenced by corporate income tax rates and the rules of how taxes paid in the host country are treated at home in this paper the exemption credit and deduction methods are considered as tax rules tax competition is modeled as a non cooperative game with respect to both corporate tax rates and the form of double taxation relief the subgame perfect equilibrium is shown to be independent of the tax rules since capital is inefficiently allocated the feasibility and the content of a cooperative contract between governments are analyzed it is argued that only the credit method requires neither compensatory payments nor fully harmonized tax rates this is consistent with the observation that tax credits are very often adopted in double taxation treaties

var estimation and forecasting when data are subject to revision we show that howrey s method for producing economic forecasts when data are subject to revision is easily generalized to handle the case where data are produced by a sophisticated statistical agency the proposed approach assumes that government estimates are efficient with a finite lag it takes no stand on whether earlier revisions are the result of news or of reductions in noise we present asymptotic performance results in the scalar case and illustrate the technique using several simple models of economic activity in each case it outperforms both conventional var analysis and the original howrey method it produces gdp forecasts that are competitive with those of professional forecasters special cases and extensions of the analysis are discussed in a series of appendices that are available online

endogenous market structures in international trade natura facit saltum abstract almost all of the large literature on international trade with imperfect competition assumes exogenous market structures the purpose of this paper is to develop a simple model that generates alternative market structures as nash equilibria for different parameterizations of the basic model equilibrium market structure is a function of the underlying technology familiar configurations such as a duopoly competing in exports or a single multinational producing in both markets arise as special cases small tax policy changes can produce large welfare effects as the equilibrium market structure shifts implying discontinuous jumps in prices quantities and profits

improving real time estimates of output and inflation gaps with multiple vintage models real time estimates of output gaps and inflation gaps differ from the values that are obtained using data available long after the event part of the problem is that the data on which the real time estimates are based is subsequently revised we show that vector autoregressive models of data vintages provide forecasts of post revision values of future observations and of already released observations capable of improving estimates of output and inflation gaps in real time our findings indicate that annual revisions to output and inflation data are in part predictable based on their past vintages this article has online supplementary materials

strategic behaviour and the rules for international taxation of capital this paper examines the welfare of a capital exporting or source country and a capital importing or host country under tax credit and tax deduction systems for the international taxation of capital because the two tax systems may create quite different strategic incentives for the countries the authors compare the equilibria in the tax setting game played by the two countries under each system they find that the tax credits system introduces an antitrade bias into the equilibrium contrary to initial impressions and that both capital exporting and capital importing countries will prefer the tax deductions scheme to tax credits copyright 1989 by royal economic society

strategic taxation of the multinational enterprise a new argument for double taxation abstract this paper analyzes the social welfare effects of multinational enterprise taxation by home and host governments in a general equilibrium model direct foreign investment arises to employ a firm specific asset abroad either a tax credit or deduction for foreign taxes paid results in the host fully taxing locally earned economic profits welfare endogenous market structure and profit results are identical in tax credit and deduction regimes because it lowers host government taxation in the subgame perfect equilibrium double taxation of foreign earned profits emerges as a weakly dominant strategy for the source government

toward a neo schumpeterian theory of the firm this article offers a sketch of what an economic theory of the firm would look like if it were founded on the thought of joseph schumpeter particularly on chapters 1 and 2 of his theory of economic development schumpeterian analysis requires an intuitively appealing and realistic conceptualization of the distinction between routine and innovative behavior and in particular a conceptualization relevant to complex organizations and complex tasks it is argued that the production theory found in mainstream economics does not meet this requirement particularly because its characterization of productive knowledge involves an overly sharp distinction between technically possible and technically impossible a distinction which has no counterpart in the realities of organizational knowledge the main elements of a schumpeterian view are described and contrasted with those in the mainstream view copyright 2006 oxford university press

credit indicators as predictors of economic activity a real time var analysis using readily available indicators of the profitability price and availability of credit the term spread junk bond spread and banks willingness to lend as reported by the federal reserve we show that it is possible to significantly improve on the real time output and employment predictions of forecasting professionals at the medium run horizons that are most relevant to policymakers and private decision makers key to this improvement is a flexible state space model of data revisions the willingness to lend variable is the best real time predictor of gdp growth for forecasting job growth all three credit indicators prove helpful

the dynamic effects of aggregate demand and supply disturbances we interpret fluctuations in gnp and unemployment as due to two types of disturbances disturbances that have a permanent effect on output and disturbances that do not we interpret the first as supply disturbances the second as demand disturbances demand disturbances have a hump shaped mirror image effect on output and unemployment the effect of supply disturbances on output increases steadily over time peaking after two years and reaching a plateau after five years

data revisions are not well behaved we document the empirical properties of revisions to major macroeconomic variables in the united states our findings suggest that they do not satisfy simple desirable statistical properties in particular we find that these revisions do not have a zero mean which indicates that the initial announcements by statistical agencies are biased we also find that the revisions are quite large compared to the original variables and they are predictable using the information set at the time of the initial announcement which means that the initial announcements of statistical agencies are not rational forecasts

corporate tax systems multinational enterprises and economic integration abstract multinational firms are known to shift profits and countries are known to compete over shifty profits two major principles for corporate taxation are separate accounting sa and formula apportionment fa these two principles have very different qualities when it comes to preventing profit shifting and preserving national tax autonomy most oecd countries use sa in this paper we show that a reduction in trade barriers lowers equilibrium corporate taxes under sa but leads to higher taxes under fa from a welfare point of view the choice of tax principle is shown to depend on the degree of economic integration

national tax policies towards product innovating multinational enterprises abstract this paper examines source and host country taxation towards multinational enterprises that engage in product development national tax policies are interdependent as they influence the range of products that the multinational enterprise develops worldwide for the case where private and public goods are perfect substitutes the source country optimally provides a tax credit and does not capture any tax revenue from the multinational s host country operations however the source country still gains from the multinational s foreign operations as they induce additional product development

the boundaries of multinational enterprises and the theory of international trade this paper begins with a review of empirical evidence on multinational firms conceptual underpinnings of a theory are developed relying in particular on the notion of knowledge capital as a mobile joint input into geographically separated production facilities this idea is embedded in a simple two country general equilibrium model that supports multinational production in equilibrium under conditions consistent with the empirical evidence the final section examines internalization and shows why certain properties of knowledge capital also imply a preference for transferring technologies internally within the firm rather than through arm s length markets

taxes tariffs and the global corporation in this paper we develop some simple models of optimal tax and tariff policy in the presence of global corporations that operate in an imperfectly competitive environment the models emphasize two important differences in the practical application of tax and tariff policy tax but not tariff policy can apply to offshore output and tariff but not tax policy can be industryspecific recognizing that multinationals production decisions are endogenous to the tax and tariff policies they face we investigate how a government should tax or subsidize domestically owned firms and how government should set trade policy

the footprint of evolutionary processes of learning and selection upon the statistical properties of industrial dynamics evolutionary theories of economic change identify the processes of idiosyncratic learning by individual firms and of market selection as the two main drivers of the dynamics of industries are such processes able to account for the statistical regularities which industrial structures and dynamics display in this work we address this question by means of a simple multi firm model formalizing the mechanisms of learning and selection as such despite its simplicity the model is able to robustly reproduce an ensemble of empirical stylized facts including ample heterogeneity in productivity distributions persistent market turbulence and fat tailed distribution of growth rates

output and unemployment dynamics in the united states 1950 1985 for us data over 1950 1985 the stochastic components of gnp growth and the unemployment rate appear to be stationary and there is substantial feedback between these variables the unconditional mean rate of unemployment in a joint model thus provides a natural benchmark in discussions of the business cycle a bivariate var model is used to describe output unemployment dynamics to estimate the degree of persistence of output innovations and to decompose output into trend and cycle the bivariate results are interpreted using a restricted var and it is shown that a closely related cyclical measure can be obtained directly from the okun s law equation

multinationals multi plant economies and the gains from trade a general equilibrium model of a multinational enterprise based on economies of multi plant operation is developed these economies are modelled as arising from the existence of a joint input whose productivity in each production facility is independent of the number of facilities maintained by a firm the multinational thus offers the world increased technical efficiency by eliminating the duplication of the joint input that would occur with independent national firms since this technical efficiency may come at the expense of increased market power the full determinants of home country host country and world welfare are considered

internalization an event study test abstract the internalization theory of multinational firms proposes that direct international investment occurs when a firm has information related intangible assets with public good properties we find that firms with characteristics suggesting the presence of information based assets experience a significantly positive stock price reaction upon announcing a foreign acquisition on the other hand firms apparently lacking such assets experience at best zero abnormal returns upon announcing overseas acquisitions

strategic trade policy and welfare foreign equity ownership is shown empirically to weaken significantly and occasionally reverse common strategic trade policy results existing levels of u s cross ownership for example reduce the average optimal export subsidy by 47 relative to the brander and spencer journal of international economics 1985 18 83 100 value in industries with particularly high cross ownership and relatively small imputed labor rents optimal subsidies fall to less than one seventh of their former level previous studies which overlook high rates of cross ownership overstate the effectiveness of strategic policies most sharply in sectors with above average expected profitability scope for strategic investments and barriers to rent dissipation

are statistical reporting agencies getting it right data rationality and business cycle asymmetry this article provides new evidence on the rationality of early releases of industrial production ip and producer price index ppi data rather than following the usual practice of examining only first available and fully revised data we examine the entire revision history for each variable thus we are able to assess for example whether earlier releases of data are in any sense less rational than later releases and when data become rational our findings suggest that seasonally unadjusted ip and ppi become rational after approximately 3 4 months whereas seasonally adjusted versions of these series remain irrational for at least 6 12 months after initial release for all variables examined we find evidence that the remaining revision is predictable from its own past or from publicly available information in other economic and financial variables in addition we find a clear increase in the volatility of revisions during recessions suggesting that early data releases are less reliable in toughe

firm size and foreign operations of multinationals the standard literature on multinationals emphasizes the importance of firm size in explaining foreign direct investment a typical statement for example by caves is that t he relation between direct investment and firm size with other factors held constant has been established statistically 1974 p 280 however descriptions of the role of firm size are often ambiguous as pointed out by hufbauer 1975 and swedenborg 1979 such descriptions do not make a clear distinction between the probability or likelihood that a firm would be a foreign investor and the extent of such investment or as expressed by swedenborg a firm s propensity to operate abroad the share of its production carried on outside its home country a study by horst 1972 which has become the basis for most statements about the importance of firm size dealt only with the probability that a firm would be a foreign investor or more specifically the probability that it would meet the criteria for being considered a multinational firm according to the definition used in the harvard studies including that of having a certain number of overseas operations cf vernon 197 1

measurement errors and monetary policy then and now should policymakers and applied macroeconomists worry about the difference between real time and final data we tackle this question by using a bayesian var with time varying parameters and stochastic volatility to show that the distinction between real time data and final data matters for the impact of monetary policy shocks the impact on final data is substantially and systematically different in particular larger in magnitude for different measures of real activity from the impact on real time data these differences have persisted over the last 40 years and should be taken into account when conducting or studying monetary policy

data revisions and the identification of monetary policy shocks abstract monetary policy research using time series methods has been criticized for using more information than the federal reserve had available to quantify the role of this criticism we estimate vars with real time data while accounting for the latent nature of many economic variables such as output our estimated monetary policy shocks are closely correlated with typically estimated measures the impulse response functions are broadly similar across estimation methods our evidence suggests that the use of revised data in var analyses of monetary policy shocks may not be a serious limitation for recursively identified systems but presents more challenges for simultaneous systems

productivity growth technical progress and efficiency change in industrialized countries this paper analyzes productivity growth in 17 oecd countries over the period 1979 1988 a nonparametric programming method activity analysis is used to compute malmquist productivity indexes these are decomposed into two component measures namely technical change and efficiency change we find that u s productivity growth is slightly higher than average all of which is due to technical change japan s productivity growth is the highest in the sample with almost half due to efficiency change jel c43 d24 in this paper we apply recently developed

real time forecasting of inflation and output growth with autoregressive models in the presence of data revisions we examine how the accuracy of real time forecasts from models that include autoregressive terms can be improved by estimating the models on lightly revised data instead of using data from the latest available vintage the benefits of estimating autoregressive models on lightly revised data are related to the nature of the data revision process and the underlying process for the true values empirically we find improvements in root mean square forecasting error of 2 4 when forecasting output growth and inflation with univariate models and of 8 with multivariate models we show that multiple vintage models which explicitly model data revisions require large estimation samples to deliver competitive forecasts copyright 2012 john wiley sons ltd

economic efficiency and frontier techniques abstract most of the literature related to the measurement of economic efficiency has based its analysis either on parametric or on non parametric frontier methods the choice of estimation method has been an issue of debate with some researchers preferring the parametric and others the non parametric approach the aim of this paper is to provide a critical and detailed review of both core frontier methods in our opinion no approach is strictly preferable to any other moreover a careful consideration of their main advantages and disadvantages of the data set utilized and of the intrinsic characteristics of the framework under analysis will help us in the correct implementation of these techniques recent developments in frontier techniques and economic efficiency measurement such as bayesian techniques bootstrapping duality theory and the analysis of sampling asymptotic properties are also considered in this paper

international investment location decisions abstract in international location tournaments governments compete for foreign investment with tax and other short run incentives such tournaments can be won if agglomeration economies are sufficiently powerful to overcome investors desire to spread investments as a hedge against risk we focus on manufacturing investments by u s multinationals in the 1980s our econometric results suggest that agglomeration economies are indeed the dominant influence on investor calculations paradoxically short run incentives have limited apparent impact on location choice we conclude that high cost tournament play is unnecessary for countries with good infrastructure development specialized input suppliers and an expanding domestic market

production theory accounting for firm heterogeneity and technical change the paper presents a new framework to assess firm level heterogeneity and to study the rate and direction of technical change building on the analysis of revealed short run production functions by hildenbrand 1981 we propose the normalized volume of the zonotope composed by vectors firms in a narrowly defined industry as an indicator of inter firm heterogeneity moreover the angles that the main diagonal of the zonotope form with the axes provide a measure of the rates and directions of technical change over time the proposed framework can easily account for n inputs and m outputs and crucially the measures of heterogeneity and technical change do not require many of the standard assumptions from production theory
