is there private information in the fx market the tokyo experiment it is a common view that private information in the foreign exchange market does not exist we provide evidence against this view the evidence comes from the introduction of trading in tokyo over the lunch hour lunch re turn variance doubles with the introduction of trading which cannot be due to public information since the flow of public information did not change with the trading rules having eliminated public information as the cause we exploit the volatility pattern over the whole day to discriminate between the two alternatives private information and pricing errors three key re sults support the predictions of private information models first the vola tility u shape flattens greater revelation over lunch leaves a smaller share for the morning and afternoon second the u shape tilts upward an impli cation of information whose private value is transitory finally the morning exhibits a clear u shape when tokyo closes over lunch and it disappears when trading is introduced

euler equations and money market interest rates a challenge for monetary policy models standard macroeconomic models equate the money market rate targeted by the central bank with the interest rate implied by a consumption euler equation we use u s data to calculate the interest rates implied by euler equations derived from a number of specifications of household preferences correlations between these euler equation rates and the federal funds rate are generally negative regression results and impulse response functions imply that the spreads between the euler equation rates and the federal funds rate are systematically linked to the stance of monetary policy our findings pose a fundamental challenge for models that equate the two

trader see trader do how do small fx traders react to large counterparties trades abstract we show that information about the counterparty of a trade affects the future trading decisions of individual traders the effect is such that traders tend to reverse their order flow in line with the better informed counterparties informed traders primarily incorporate their own private as well as publicly available information into prices whereas uninformed traders mainly magnify the effect of the informed this pattern of interaction among traders extends to different order types traders treat their own and others market orders as more informative than limit orders

an equilibrium model of the business cycle with household production and fiscal policy the authors estimate a dynamic general equilibrium model of the u s economy that includes an explicit household production sector and stochastic fiscal variables they use their estimates to investigate two issues first the authors analyze how well the model accounts for aggregate fluctuations they find that household production has a significant impact and reject a nested specification in which changes in the home production technology do not matter for market variables second the authors study the effects of some simple fiscal policy experiments and show that the model generates different predictions for the effects of tax changes than similar models without home production copyright 1997 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

why does household investment lead business investment over the business cycle household investment leads nonresidential business fixed investment over the u s business cycle because real business cycle theory has not been able to account for this observation it represents a potent challenge to the view that transitory productivity disturbances are the main source of aggregate fluctuations this paper reconciles rbc theory with the investment dynamics by extending the traditional home production model to make household capital complementary to business capital and labor in market production empirical evidence suggesting that household capital is a complementary input in market production is also presented

so what orders do informed traders use we present a simple glosten milgrom type equilibrium model to analyze the decision of informed traders on whether to use limit or market orders we show that even after incorporating an order s price impact not only may informed traders prefer to use limit orders but the probability that they submit limit orders can be so high that limit orders convey more information than market orders we further show that the horizon of the private information is critical for this decision and is positively related to the use of limit orders our empirical analysis using torq suggests that informed traders do prefer limit orders to market orders and that limit orders are indeed more informative our model is in contrast to the literature that assumes that informed traders use market orders only and the literature that examines the limit order versus the market order decision of uninformed traders

housing dynamics over the business cycle housing construction measured by housing starts leads gdp in a number of countries measured as residential investment the lead is observed only in the united states and canada elsewhere residential investment is coincident variants of existing theory however predict housing construction lagging gdp in all countries in the sample nominal interest rates are low ahead of gdp peaks introducing long term nominal mortgages and an estimated process for nominal interest rates into a standard model aligns the theory with observations on starts as mortgages transmit nominal rates into real housing costs longer time to build makes residential investment cyclically coincident abstract from author

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

the role of intratemporal adjustment costs in a multisector economy abstract in this paper we construct a multisector business cycle model which is capable of reproducing the procyclical behavior of cross sector measures of capital employment and output we start by documenting the difficulty that a standard variant of a conventional real business cycle model has in accounting for these facts we then show how the introduction of intratemporal adjustment costs for investment can significantly enhance the performance of such a model these costs make it difficult to alter the composition of production of new capital goods the presence of these costs eliminates many counterfactual observations of the model that would otherwise be present the dynamic response of variables in the model is different from what one would observe in the standard one sector model we also examine the implications of imposing intratemporal adjustment costs for labor the model can also account for the cross sector behavior of employment observed in the data

house prices borrowing constraints and monetary policy in the business cycle i develop a general equilibrium model with sticky prices credit constraints nominal loans and asset prices changes in asset prices modify agents borrowing capacity through collateral value changes in nominal prices affect real repayments through debt deflation monetary policy shocks move asset and nominal prices in the same direction and are amplified and propagated over time the financial accelerator is not constant across shocks nominal debt stabilises supply shocks making the economy less volatile when the central bank controls the interest rate i discuss the role of equity debt indexation and household and firm leverage in the propagation mechanism finally i find that monetary policy should not target asset prices as a means of reducing output and inflation volatility

housing taxation and capital accumulation this paper studies the impact of the preferential tax treatment of housing capital in a dynamic general equilibrium life cycle economy populated by heterogeneous individuals the model includes the main housing tax provisions currently in place in the u s and a minimum downpayment requirement upon purchasing non divisible houses the tax code makes the return on housing capital larger than that on business capital which distorts the lifetime profile and composition of individuals savings the wedge between the two rates of return emanates from the failure to tax imputed rents and is amplified by the presence of mortgage interest deductibility simulations show that individuals at all income levels would rather live in a world where imputed rents are taxed or one where mortgage interest payments are not deductible furthermore distributional effects are much smaller than conventionally believed

limit orders depth and volatility evidence from the stock exchange of hong kong we investigate the role of limit orders in the liquidity provision in a pure orderdriven market results show that market depth rises subsequent to an increase in transitory volatility and transitory volatility declines subsequent to an increase in market depth we also examine how transitory volatility affects the mix between limit orders and market orders when transitory volatility arises from the ask bid side investors will submit more limit sell buy orders than market sell buy orders this result is consistent with the existence of limit order traders who enter the market and place orders when liquidity is needed

imperfect competition among informed traders we analyze competition among informed traders in the continuous time kyle 1985 model as foster and viswanathan 1996 do in discrete time we explicitly describe the unique linear equilibrium when signals are imperfectly correlated and confirm the conjecture of holden and subrahmanyam 1992 that there is no linear equilibrium when signals are perfectly correlated one result is that at some date and at all dates thereafter the market would have been more informationally efficient had there been a monopolist informed trader instead of competing traders the relatively large amount of private information remaining near the end of trading causes the market to approach complete illiquidity copyright the american finance association 2000

does anonymity matter in electronic limit order markets we develop a model in which limit order traders possess volatility information we show that in this case the size of the bid ask spread is informative about future volatility moreover if volatility information is in part private we establish that i the size of the bid ask spread and ii its informativeness about future volatility should change in the same direction when limit order traders identifiers stop being disclosed we test these predictions using data from the paris bourse as expected we find that the average quoted spread and its informativeness are significantly smaller when limit order traders identifiers are concealed these findings suggest that the limit order book is a channel for volatility information

fdi impact and spillover evidence from china s electronic and textile industries m ultinational corporations mncs may invest in a host country when they possess non tangible productive assets that cannot be easily licensed but can be transferred within the firm direct equity participation in the host country is therefore required for mncs to reap the rents from their nontangible productive assets which may include technological know how marketing and managing skills relationships with suppliers and customers and reputation if foreign direct investment fdi does effectively convey these assets we should expect fdi to boost the productivity of the host country firms that receive fdi a more complex issue is the indirect spillover effects of fdi to non fdi domestic firms to the extent that fdi may bring new products and technologies to the host country non fdi receiving domestic firms may also stand to benefit from fdi through personnel turnover demonstration effects and knowledge spillovers the presence of fdi in a certain industry however may exert adverse effect on domestic firms in that industry by enjoying better technologies and lower production costs firms with fdi may cut into the market share of domestic firms without fdi in a short run imperfectly competitive market structure the productivity of domestic firms may be reduced when sales fall so that fixed costs are spread over fewer units in the long run however the increased competition induced by the increased presence of fdi in domestic industries may force

transactions volume and volatility we show that the positive volatility volume relation documented by numerous researchers actually reflects the positive relation between volatility and the number of transactions thus it is the occurrence of transactions per se and not their size that generates volatility trade size has no information beyond that contained in the frequency of transactions our results suggest that theoretical research needs to entertain scenarios in which 1 both the frequency and size of trades are endogenously determined yet 2 the size of trades has no information content beyond that contained in the number of transactions article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

time varying liquidity in foreign exchange abstract this paper addresses whether currency trades have greater price impact when public information is flowing rapidly we develop an optimizing model to account for why public news should increase the price impact of trades using transaction data made available by electronic trading we test whether trades following macroeconomic news have higher price impact they do price impact per dollar traded is about 10 percent higher per news announcement in the previous hour after controlling for public information flow we do not find evidence that liquidity depends on trading volume and return volatility the findings provide policy makers with guidance for the timing and magnitude intervention

money prices interest rates and the business cycle the mechanisms governing the relationship of money prices and interest rates to the business cycle are the most studied and most disputed topics in macroeconomics in this paper we first document key empirical aspects of this relationship we then ask how well three benchmark rational expectations macroeconomic models a real business cycle model a sticky price model and a liquidity effect model account for these central facts while the models have diverse successses and failures none can account for the fact that real and nom inal interest rates are inverted leading indicators of real economic activity that is none of the models captures the post war u s business cycle fact that a high real or nominal interest rate in the current quarter predicts a low level of real economic activity two to four quarters in the future i introduction the positive correlation of monetary aggregates and real economic activity over the course of many business cycles is a key empirical fact about the u s economy indeed the dynamic dimension of this covariation is so strong and stable that a monetary variable has long been included in the commerce department s index of leading economic indica tors while this pattern of cyclical comovement is widely agreed upon its interpretation is not some macroeconomists view money as purely passive with a positive response to varying levels of economic activity producing the positive correlation others view changes in the quantity of money as an important perhaps dominant source of economic fluctua tions frequently the real effects of monetary changes are suggested to arise from frictions in commodity labor or financial markets in economic theories that describe the influence of these frictions the transmission mechanism from monetary changes to real activity is typically viewed as involving interest rates and the price level the primary goal of this paper is to evaluate three models that explain the link between money prices interest rates and the business cycle we do this in three steps first we docu ment the cyclical behavior of these variables in the united states over the postwar period second we construct three quantitative rational expectations models of macroeconomic activity i a real business cycle model with endogenous money ii a model of commodity market frictions with mon etary non neutralities arising from gradual adjustment of goods prices and iii a model of financial market frictions with monetary non neutralities arising from gradual adjust ments of portfolios finally we compare the models predic tion for the business cycle behavior of money prices and interest rates with the data in exploring the predictions of these models we take the stock of money to be one of several exogenous variables in the system all of our models are capable of generating a forecasting role for money relative to real economic activity similar to that found in the u s data in the real business model monetary changes can forecast real activity because productivity is related to many underlying sources of shocks and because these real shocks also affect the money stock in the models with sticky prices and liquidity effects short hand names for the models with frictions in the com modity and financial markets monetary changes have an additional direct positive effect on aggregate output the outline of the paper is as follows section ii describes the data and documents its business cycle characteristics section iii outlines the three macroeconomic models and develops the particular quantitative versions of the models used in our analysis our main empirical results are pre sented in section iv and section v summarizes our results and concludes

information linkages and correlated trading in a market with informationally connected traders the dynamics of volume price informativeness price volatility and liquidity are severely affected by the information linkages every trader experiences with his peers we show that in the presence of information linkages among traders volume and price informativeness increase moreover we find that information linkages improve or damage market depth and lower or boost the traders profits according to whether these linkages convey positively or negatively correlated signals finally our model predicts patterns of trade correlation consistent with those identified in the empirical literature trades generated by neighbor traders are positively correlated and trades generated by distant traders are negatively correlated

stealth trading which traders trades move stock prices usingaudit trail data for a sample of nyse firms we show that medium size trades are associated with a disproportionately large cumulative stock price change relative to their proportion of all trades and volume this result is consistent with the predictions of barclay and warner s 1993 stealth tradinghypothesis we find that the source of this disproportionately large cumulative price impact of medium size trades is trades initiated by institutions this result is robust to various sensitivity checks our findings appear to confirm street lore that institutions are informed traders 2001 elsevier science s a all rights reserved

the market microstructure of central bank intervention abstract how quickly do central bank intervention operations impact the foreign exchange market and do intra daily market conditions influence the effectiveness of central bank interventions this paper uses high frequency intra daily data to examine the relationship between the efficacy of intervention operations and the state of the market at the moment that the operation is made public the results indicate that some traders typically know that the fed is intervening at least 1 h prior to the public release of the information in newswire reports also the evidence suggests that the timing of intervention operations matters interventions that occur during heavy trading volume that are closely timed to scheduled macro announcements and that are coordinated with another central bank are the most likely to have large effects

home production meets time to build an innovation in this paper is to introduce a time to build technology for the production of market capital into a model with home production our main finding is that the two anomalies that have plagued all household production models the positive correlation between business and household investment and household investment s leading business investment over the business cycle are resolved when time to build is added

long lived private information and imperfect competition we develop a multi period auction model in which multiple privately informed agents strategically exploit their long lived information we show that such traders compete aggressively and cause most of their common private information to be revealed very rapidly in the limit as the interval between auctions approaches zero market depth becomes infinite and all private information is revealed immediately these results are in contrast to those of kyle 1985 in which the monopolistic informed trader causes his information to be incorporated into prices gradually and when the interval between auctions is vanishingly small market depth is constant over time fama 1970 defines a strong form efficient market as one in which security prices fully reflect all available information including both publicly and privately held information in a pioneering and influential article kyle 1985 develops a model in which a single privately informed trader with long lived information optimally exploits his monopoly power over time kyle s 1985 main results are i the informed trader trades in a gradual manner so that his information is incorporated into prices at a slow almost linear rate and ii when auctions are held continuously the depth of the market is constant over time however kyle s 1985 assumption of a single informed trader is strong in the sense that in actual financial markets it is reasonable to expect that at least a few players will have access to private information and will trade in the knowledge that they will face competition with other informed agents in the market 1 we develop a multi period auction model in which multiple strategic informed traders optimally exploit their long lived informational advantage we thus explore the restrictiveness of kyle s assumption of a single informed trader and also examine

local information in foreign exchange markets abstract this study shows that order flow in a foreign exchange market appears to have permanent price impact only if it comes from certain regions these regions are as predicted by the local information hypothesis centers of political and financial decision making it is revealing that orders from other regions only show a very short lived but no permanent price impact local information is so important that it carries over from the usually considered market orders to aggressively priced limit orders too the finding is robust to common news shocks to the consideration of feedback trading and to further controls

markets and the structure of the housebuilding industry an international perspective this paper sets out to examine why the modern housebuilding industry is organised in the ways it is and to identify some implications for the wider operation of housing markets it concentrates on advanced economies and the impacts of market conditions regulatory constraints production characteristics institutional structures and land supply widespread differences occur across countries in the ways in which housebuilding is institutionally structured it is argued that these differences are generally explicable in economic terms and that regulatory practices determine much of the variation

trading volume and serial correlation in stock returns this paper investigates the relationship between aggregate stock market trading volume and the serial correlation of daily stock returns for both stock indexes and individual large stocks the first order daily return autocorrelation tends to decline with volume the paper explains this phenomenon using a model in which risk averse market makers accommodate buying or selling pressure from liquidity or noninformational traders changing expected stock returns reward market makers for playing this role the model implies that a stock price decline on a high volume day is more likely than a stock price decline on a low volume day to be associated with an increase in the expected stock return
