asymmetric price adjustment and economic fluctuations this paper considers a possible explanation for asymmetric adjustment of nominal prices the authors present a menu cost model in which positive trend inflation causes firms relative prices to decline automatically between price adjustments in this environment shocks that raise firms desired prices trigger larger price responses than shocks that lower desired prices the authors use this model of asymmetric adjustment to address three issues in macroeconomics the effects of aggregate demand the effects of sectoral shocks and the optimal rate of inflation copyright 1994 by royal economic society

vintage technologies and skill constraints evidence from u s exports of new and used machines when countries import production machinery they must choose between new and used equipment this article looks at that choice in the presence of labor saving technical progress and complementarity between technologies and skills within the firm it develops a theoretical model of the market for used machines it then analyzes data on united states u s exports of metalworking machine tools by country of destination classifying machines according to their vintage and their technological characteristics the data show that the share of used equipment imported is higher if the importing country has a lower level of development as measured by income per capita econometric estimation of the determinants of this share shows that it also is higher the greater is the technological change embodied in the machine or the greater is the change in the skills required to run the machine efficiently these results indicate that technological factors and skill constraints may be as important as factor prices in determining the choice of technique in developing countries the policy recommendation emerging from this work avoid constraints on imports of used equipment is similar to that in the existing literature but the reasoning is different instead of emphasizing inappropriate capital labor ratios for low wage countries the results indicate that investment in advanced technologies is effective only if importing countries have the skills to use them

jumps cojumps and macro announcements we use recently proposed tests to extract jumps and cojumps from three types of assets stock index futures bond futures and exchange rates we then characterize the dynamics of these discontinuities and informally relate them to us macroeconomic releases before using limited dependent variable models to formally model how news surprises explain co jumps nonfarm payroll and federal funds target announcements are the most important news across asset classes trade balance shocks are important for foreign exchange jumps we relate the size frequency and timing of jumps across asset classes to the likely sources of shocks and the relation of asset prices to fundamentals in the respective classes

stylized facts and regime changes are prices procyclical we investigate empirically the stability of the correlation between output growth and inflation using a technique that allows for changes in regime we look at recent quarterly data for the g4 and at historical data for the u s and u k we find evidence of changes both in means and variances in both sources of data in the quarterly data we find that the covariance between output growth and inflation is typically negative in the historical data we find as suggested in previous studies that inflation was procyclical especially in the inter war years but has been countercyclical in the post war period

dynamic asset allocation with event risk major events often trigger abrupt changes in stock prices and volatility we study the implications of jumps in prices and volatility on investment strategies using the event risk framework of duffie pan and singleton 2000 we provide analytical solutions to the optimal portfolio problem event risk dramatically affects the optimal strategy an investor facing event risk is less willing to take leveraged or short positions the investor acts as if some portion of his wealth may become illiquid and the optimal strategy blends both dynamic and buy and hold strategies jumps in prices and volatility both have important effects

home bias and cross border taxation abstract the relationship between cross border taxation and free float home bias is examined this explicitly recognizes that insider shares are unavailable to foreigners other important explanations for home bias information asymmetry behavioural and governance issues are controlled when examining the impact of cross border tax variables in our sample of countries about sixty percent eighty percent withhold taxes on realized capital gains dividends of foreign investors and about thirty percent of the mature economies provide imputation of taxes paid on dividend income by domestic corporations dividend imputation is a statistically significant impediment to cross border equity flows a tax credit variable for foreign taxes paid on dividends is constructed and found to be statistically significant in reducing home bias a relatively high foreign tax rate that cannot be offset by tax credits is found to significantly increase home bias these results hold for float adjusted home bias and traditional international portfolio home bias

the cyclical behavior of prices abstract the procyclical behavior of prices has been a staple of business cycle lore since the work of the early nber business cycle researchers this paper reexamines that empirical fact the aggregate data do not support procyclical price movements as a stable feature of the business cycle the only episode where it is a robust feature of the data is the period between the two world wars particularly the period of the great depression

improved estimates of higher order comoments and implications for portfolio selection in the presence of nonnormally distributed asset returns optimal portfolio selection techniques require estimates for variance covariance parameters along with estimates for higher order moments and comoments of the return distribution this is a formidable challenge that severely exacerbates the dimensionality problem already present with mean variance analysis this article extends the existing literature which has mostly focused on the covariance matrix by introducing improved estimators for the coskewness and cokurtosis parameters we find that the use of these enhanced estimates generates a significant improvement in investors welfare we also find that it is only when improved estimators are used that portfolio selection with higher order moments dominates mean variance analysis from an out of sample perspective the author 2009 published by oxford university press on behalf of the society for financial studies all rights reserved for permissions please email journals permissions oxfordjournals org oxford university press

systemic co jumps abstract the simultaneous occurrence of jumps in several stocks can be associated with major financial news triggers short term predictability in stock returns is correlated with sudden spikes of the variance risk premium and determines a persistent increase decrease of stock variances and correlations when they come along with bad good news these systemic events and their implications can be easily overlooked by traditional univariate jump statistics applied to stock indices they are instead revealed in a clearly cut way by using a novel test procedure applied to individual assets which is particularly effective on high volume stocks

betting your favorite to win costly reluctance to hedge desired outcomes we examined whether people reduce the impact of negative outcomes through emotional hedging betting against the occurrence of desired outcomes we found substantial reluctance to bet against the success of preferred u s presidential candidates and major league baseball national football league national collegiate athletic association ncaa basketball and ncaa hockey teams this reluctance was not attributable to optimism or a general aversion to hedging reluctance to hedge desired outcomes stemmed from identity signaling a desire to preserve an important aspect of the bettor s identity reluctance to hedge occurred when the diagnostic cost of the negative self signal that hedging would produce outweighed the pecuniary rewards associated with hedging participants readily accepted hedges and pure gambles with no diagnostic costs they also more readily accepted hedges with diagnostic costs when the pecuniary rewards associated with those hedges were greater reluctance to hedge identity relevant out

international portfolio nondiversification and exchange rate variability abstract incomplete international portfolio diversification is implied by an equilibrium models of exchange rates with nontraded goods the model can also explain the greater correlation between consumption and income within a country than between consumption across countries nontraded goods make more stringent the elasticity conditions required to explain exchange rate variability resulting from current productivity disturbances though not from disturbances to fiscal policies or the prospective return to investment the model is also consistent with international real interest rate differentials changes over time in the current account and relative wealth across nations and observed time series properties of exchange rates

home bias in equity portfolios inflation hedging and international capital market equilibrium we test whether the home bias in equity portfolios is caused by investors trying to hedge inflation risk the empirical evidence is consistent with this motive only if investors have very high levels of risk tolerance and equity returns are negatively correlated with domestic inflation we then develop a model of international portfolio choice and equity market equilibrium that integrates inflation risk and deadweight costs using this model we estimate the levels of costs required to generate the observed home bias in portfolios consistent with different levels of risk aversion for a level of risk aversion consistent with standard estimates of the domestic equity market risk premium these costs are about a few percent per annum greater than observable costs such as withholding taxes thus the home bias cannot be explained by either inflation hedging or direct observable costs of international investment unless investors have very low levels of risk aversion article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

what determines mutual fund trading in foreign stocks abstract we examine the portfolio rebalancing measured by the equity churn rate of mutual funds from 29 countries based on annual stockholdings over the 1999 2006 period we find that funds more often trade the stocks of companies located in countries with higher degree of information asymmetry and are less familiar to fund managers after we control for the effects of stock market development and investor protection consistent with the behavioral bias fund managers more often rebalance stocks in foreign markets that perform well this bias is exacerbated when fund managers are less familiar with and less informed about those markets

a new approach to measuring financial contagion this article proposes a new approach to evaluate contagion in financial markets our measure of contagion captures the coincidence of extreme return shocks across countries within a region and across regions we characterize the extent of contagion its economic significance and its determinants using a multinomial logistic regression model applying our approach to daily returns of emerging markets during the 1990s we find that contagion is predictable and depends on regional interest rates exchange rate changes and conditional stock return volatility evidence that contagion is stronger for extreme negative returns than for extreme positive returns is mixed

on the optimal timing of capital taxes for many kinds of capital depreciation rates change systematically with the age of the capital consider an example that captures essential aspects of human capital both regarding its accumulation and its depreciation a worker obtains knowledge in period 0 then uses this knowledge in production in periods 1 and 2 and thereafter retires here depreciation accelerates it occurs at a 100 rate after period 2 and at a lower perhaps zero rate before that the present paper analyzes the implications of non constant depreciation rates for the optimal timing of taxes on capital income the main finding is that under natural assumptions the path of tax rates over time must be oscillatory oscillatory tax rates are optimal when depreciation rates accelerate with the age of the capital as in the above example and provided that the government can commit to the path of future tax rates but cannot apply different tax rates in a given year to different vintages of capital

oil and the macroeconomy since world war ii all but one of the u s recessions since world war ii have been preceded typically with a lag of around three fourths of a year by a dramatic increase in the price of crude petroleum this does not mean that oil shocks caused these recessions evidence is presented however that even over the period 1948 72 this correlation is statistically significant and nonspurious supporting the proposition that oil shocks were a contributing factor in at least some of the u s recessions prior to 1972 by extension energy price increases may account for much of post opec macroeconomic performance

the reality of stock market jumps diversification abstract we propose a non parametric procedure for estimating systemic co jumps and independent idiosyncratic jumps for 35 stock markets and study news associated with these jumps as reported in factiva and bloomberg from 1988 to 2014 our results suggest that it is important to distinguish between systemic co jumps and idiosyncratic jumps we find both types of jumps have important implications for home bias investors while idiosyncratic jumps have economically significant impact on portfolio weights for emerging markets our news analysis suggests systemic jumps are typically caused by currency crises sectoral failure liquidity issues and deteriorating economic climate while idiosyncratic jumps are usually caused by political unrest currency instability and large firm effects on small economies in fact many of the idiosyncratic jumps share the same origin although different stock markets experienced the impact differently at different times

do trade costs in goods market lead to home bias in equities abstract two of the main puzzles in international economics are the consumption and the portfolio home biases we solve for international equity portfolios in a two country two good stochastic equilibrium model with trade costs in goods markets we show that introducing trade costs as suggested by obstfeld and rogoff obstfeld m rogoff k 2000a the six major puzzles in international macroeconomics is there a common cause nber macroeconomics annual 15 is not sufficient to explain these two puzzles simultaneously on the contrary we find that trade costs create a foreign bias in portfolios for reasonable parameter values this result is robust to the addition of non tradable goods for standard calibrations of the preferences

on the effects of barriers to international investment a simple model is presented in which it is costly for domestic investors to hold foreign assets the implications of the model for the composition of optimal portfolios at home and abroad are derived it is shown that all foreign assets with a beta larger than some beta plot on either one of two security market lines some foreign assets with a beta smaller than are not held by domestic investors even if their expected return is increased slightly while it is obviously not true that asset markets are completely segmented between countries there is evidence of barriers to international investment although reality seems to lie in that grey area between complete segmentation and no segmentation at all most international asset pricing models are concerned with the extreme case of no barriers to international investment no effort seems to have been made to study the effect on portfolio choice of such barriers which make it costly to hold foreign securities as opposed to domestic securities but which do not in general render international diversification so onerous that investors avoid foreign securities completely casual empiricism suggests that models without barriers to international investment should be suspect those models cannot explain why it appears that in every country investors on average hold more domestic securities than would be required if they held the world market portfolio 2 this paper constructs a model of international asset pricing in which there is a cost associated with holding either long or short risky foreign securities for the sake of simplicity in most of the paper we assume that while domestic investors face barriers to international investment foreign investors face no such barriers it turns out that nothing significant is lost with such an assumption the main conclusions of this paper for the case in which foreign investors face no barriers to international investment are 1 in the presence of barriers to international investment some risky foreign

integration vs segmentation in the canadian stock market this paper examines the issue of integration versus segmentation of the canadian equity market relative to a global north american market we compare the international and domestic versions of the capm and find that integration or the mean variance efficiency of the global market index is rejected by the data segmentation is the preferred model based on a maximum likelihood procedure correcting for thin trading we further divide the sample into securities that are interlisted in canada and the u s and those that are not integration is rejected for both groups which indicates that the source of segmentation can be traced to legal barriers based on the nationality of issuing firms empirical studies of international capital markets have left the issue of segmentation versus integration largely unresolved yet the question of national or international pricing of assets has crucial implications for financial decisions if national stock markets are segmented then international portfolios should display superior risk adjusted performance because some of the priced domestic systematic risk is diversifiable also with segmentation many irrelevance propositions for corporate financial strategy break down home firms face optimal hedging decisions as well as optimal foreign versus home borrowing decisions finally criteria for capital budgeting decisions will be quite different under national and international pricing the purpose of this paper is to shed some light on this integration versus segmentation question for the canadian equity market vis a vis a global north american market in this paper integration is defined2 as a situation where investors earn the same risk adjusted expected return on similar financial instruments in different national markets the key problem of course is the pricing

how many stocks make a diversified portfolio we show that a well diversified portfolio of randomly chosen stocks must include at least 30 stocks for a borrowing investor and 40 stocks for a lending investor this contradicts the widely accepted notion that the benefits of diversification are virtually exhausted when a portfolio contains approximately 10 stocks we also contrast our result with the levels of diversification found in studies of individuals portfolios

systemic risk and international portfolio choice returns on international equities are characterized by jumps moreover these jumps tend to occur at the same time across countries leading to systemic risk we capture these stylized facts using a multivariate system ofjump diffusion processes where the arrival of jumps is simultaneous across assets we then determine an investor s optimal portfolio for this model of returns systemic risk has two effects one it reduces the gains from diversification and two it penalizes investors for holding levered positions we find that the loss resulting from diminished diversification is small while that from holding very highly levered positions is large returns on international equities are characterized by jumps 1 moreover these jumps tend to occur at the same time across countries implying that conditional correlations between international equity returns tend to be higher in periods of high market volatility or following large downside moves 2 our objective in

ict and productivity growth in the united kingdom this paper develops new estimates of investment in and output of information and communication technology ict these new estimates imply that gdp growth has been significantly understated particularly since 1994 a growth accounting approach is employed to measure the contribution of ict to the growth of both aggregate output and aggregate input on both counts the contribution of ict has been rising over time from 1989 to 1998 ict output contributed a fifth of overall gdp growth since 1989 55 per cent of capital deepening the growth of capital per hour worked has been contributed by ict capital since 1994 this proportion has risen to 90 per cent ict capital deepening accounts for 25 per cent of the growth of labour productivity over 1989 98 and 48 per cent over 1994 8 but even when output growth is adjusted for the new ict estimates both labour productivity and tfp growth are still found to slow down after 1994

a near rational model of the business cycle with wage and price inertia this paper presents a model in which insignificantly suboptimal behavior causes aggregate demand shocks to have significant real effects the individual loss to agents with inertial price wage behavior is second order in terms of the parameter describing the shock while the effect on real economic variables is first order thus significant changes in business activity can be generated by anticipated money supply changes provided that some agents are willing to engage in nonmaximizing behavior which results in small losses

prices output and hours an empirical analysis based on a sticky price model abstract i show that a simple sticky price model based on rotemberg 1982 is consistent with a variety of facts concerning the correlation of prices hours and output it is consistent with the negative correlation between forecastable movements in prices and output as well as the smaller negative correlation between forecastable movements in prices and hours it is also consistent with the positive correlations of unexpected movements in prices output and hours these patterns are harder to reconcile with the flexible price version of the model in particular they require that money respond differently to forecastable and to unforecastable real shocks

long term global market correlations the correlation structure of the world equity markets varied considerably over the past 150 years and was high during periods of economic integration we decompose diversification benefits into two parts one component due to variation in the average correlation across markets and a another component due to the variation in the investment opportunity set from this we infer that periods of globalization have both benefits and drawbacks for international investors globalization expands the opportunity set but as a result the benefits from diversification rely increasingly on investment in emerging markets

confidence in the familiar an international perspective one striking feature of intemrnational portfolio investment is the extent to which equity portfolios are concentrated in the domestic equity market of the investor the home bias puzzle i examine the role of investors perception of foreign investment risk on their portfolio choices the expected retumrns and risk of foreign investment are specified through an asset pricing model with the home portfolio being the benchmark asset pastor s 2000 domestic capm the model serves as a reference point around which investors can center their prior beliefs i focus on investors prior beliefs that are consistent with the literature on confidence in the familiar foreign equities in terms of both expected returns and risk being viewed less favorably than domestic equities these prior beliefs are then combined with the data on g7 equities and the revised beliefs are used to obtain the global optimal asset allocation to hold predominantly domestic equities each g7 investor has to believe that the risk of foreign investment is several times higher than the actual risk the home bias is more of a puzzle for a u s investor during the 1970s specifying investors prior beliefs around the world capm does not help resolve the puzzle

the ability of global stock exchange mechanisms to mitigate home bias evidence from euronext this paper examines the effects on equity home bias of two mechanisms adopted by euronext when it was formed by the merger of four european countries stock exchanges in 2002 the two structural mechanisms are the integration of trading platforms across the four predecessor exchanges and the creation of named segments of the integrated exchange on which firms could voluntarily list by precommitting to enhanced disclosure and transparency employing a difference in differences research design using other european union companies as a control group we document that the integration of the euronext market was associated with a reduction in home bias for firms listed on the named segments of the euronext exchange but not for the nonsegment euronext firms our results suggest that the reduction in transaction costs from the integration of the trading platforms did not make the nonsegment euronext firms more attractive to the specific investors for whom the transaction costs were reduced on the other hand the decrease in information costs due to the precommitments to enhanced transparency made the segment firms more attractive to all categories of foreign investors consistent with the information costs hypothesis this paper was accepted by mary barth accounting

the impact of global equity offerings this article examines the impact of u s firms issuing equity in multiple markets we compare the stock price reactions to announcements of global equity offers to a control group of issues offered exclusively in the domestic u s market all else equal the adverse price reaction that typically accompanies equity issuance is reduced by 0 8 percent when some shares are sold abroad the overall evidence suggests global offers are effective in expanding demand and reducing the price pressure effects associated with share issuance the benefits of global offers appear to be associated with an increase in the number of foreign shareholders the search for new capital markets and lower costs of capital is an ongoing search for most firms in recent years the number of u s firms issuing common equity in international markets has increased significantly in 1985 u s firms raised 89 million through follow on equity offers in foreign markets and this amount increased to 18 915 million in 1995 a greater than 200 fold increase in nominal terms this paper focuses on follow on global equity issues by u s firms and attempts to assess why firms widely acknowledged to have access to broad and deep domestic capital markets increasingly seek to raise equity abroad the global equity offerings we examine involve a simultaneous sale of common equity at the same offer price in the u s market and one or more international markets we examine the characteristics of the issuers and issues and investigate to what extent the wider distribution of shares affects the pricing and costs of these issues our main line of inquiry examines whether the distribution of shares to multiple markets results in a higher offer price for equity shares than would be obtained had the shares been sold exclusively in the u s market domes

are jumps in stock returns diversifiable evidence and implications for option pricing this paper studies the diversiflability of jumps in stock returns it presents a multivariate time series model of the stochastic process for an index and its component stocks that explicitly admits discrete common jumps maximum likelihood estimation for such a model is developed and applied to the daily major market index and its component stocks for the period 1985 through 1990 the paper finds that poisson distributed jumps observed from both the index and its component stocks constitute nondiversiflable risk implying that the standard assumption in option pricing that these jumps are not priced may be invalid

the comovement between real activity and prices in the g7 in this paper we study the short run and long run comovement between prices and real activity in the g7 countries during the postwar period using var forecast errors and frequency domain filters we find several patterns of the correlation coefficients that are robust across countries and time periods typically the correlation coefficients at long run horizons are significantly negative and the correlation coefficients at short run horizons are substantially higher additionally there is evidence of positive correlation at short run forecast horizons for some countries

capital maintenance and depreciation over the business cycle abstract this paper develops and estimates a stochastic general equilibrium model with capital maintenance which affects endogenously the depreciation rate of capital the estimate of maintenance series is found to track survey based measures for canada quite closely and to generate the procyclical pattern of maintenance observed in the data we use our model estimates to infer the time profile of equipment capital depreciation in canadian and us manufacturing the depreciation rate is estimated to be volatile and highly procyclical in both countries

a jump diffusion model for option pricing brownian motion and normal distribution have been widely used in the black scholes option pricing framework to model the return of assets however two puzzles emerge from many empirical investigations the leptokurtic feature that the return distribution of assets may have a higher peak and two asymmetric heavier tails than those of the normal distribution and an empirical phenomenon called volatility smile in option markets to incorporate both of them and to strike a balance between reality and tractability this paper proposes for the purpose of option pricing a double exponential jump diffusion model in particular the model is simple enough to produce analytical solutions for a variety of option pricing problems including call and put options interest rate derivatives and path dependent options equilibrium analysis and a psychological interpretation of the model are also presented

the cyclical behavior of prices and relative prices i introduction correlations between shocks to prices and output provide evidence on the source of macroeconomic shocks for example den haan 2000 found positive correlations at short forecast horizons and negative correlations at longer forecast horizons for the consumer price index cpi and the index of industrial production ip 1 he interpreted these results to mean that demand shocks dominate in the short run while supply shocks dominate in the long run several other papers confirm the positive correlation between the cpi and the ip at short forecast horizons on the other hand some of these same authors have found a negative correlation between real gross domestic product gdp and the gdp deflator at short forecast horizons 2 this difference is disappointing since the results provide conflicting evidence on the nature of shocks at short horizons and puzzling since the cpi and the deflator are positively correlated as are ip and gdp an important distinction between pairing gdp with its deflator and pairing ip with the cpi is the extent to which products in the output index are matched to products in the price index gdp and the gdp deflator are based on the same set of goods and services on the other hand ip contains products such as those produced by mining whose prices are not included in the cpi and the cpi includes products such as housing services that are not included in ip in this paper we argue that the correlation between mismatched price and output indexes such at the cpi and ip can be and often is misleading the explanation for why it is important to use matched indexes of price and output is simple suppose that you are interested in the correlation between the price and the quantity of apples if instead you compute the correlation between the price of oranges and the quantity of apples the correlation is correct only if the relative price of oranges to apples does not vary with the quantity of apples if the relative price varies then the mismatched correlation differs in magnitude from and may even have the opposite sign of the matched one correlations between both matched and mismatched pairs are mostly negative positive correlations are rare and small for matched pairs but more frequent for mismatched pairs for example investment and the investment deflator are negatively correlated while investment and the consumption deflator are positively correlated our analysis below shows that these correlations imply that the relative price of consumption to investment may be positively correlated with investment previous authors have noted that the relative price of nondurables is procyclical which is consistent with the bias we find for mismatches these previous results are based on correlations between detrended variables we confirm that these findings hold when considering the correlation between forecast errors of the relative price of nondurables to durables and output measures 3 because there is no price index that matches ip and because correlations between mismatched price and output measures likely differ in size and may have the opposite sign of the correlation for matched pairs there is no way to be certain of the cyclical nature of the prices of goods included in the index of ip an examination of gdp components and price deflators provides reasons to be skeptical of the positive correlation between the cpi and the ip first matched pairs of price indexes and gdp components have small or negative correlations second correlations between mismatched price indexes and gdp components show that the bias created by mismatches is sometimes substantial further this bias tends to be positive when prices of nondurable goods such as the cpi or consumption deflator are mismatched with gdp components composed mostly of durable goods finally when ip is paired with deflators for durables investments or goods the correlation is either small or negative at short forecast horizons

relative price changes as aggregate supply shocks this paper proposes a theory of supply shocks or shifts in the short run phillips curve based on relative price changes and frictions in nominal price adjustment when price adjustment is costly firms adjust to large shocks but not to small shocks and so large shocks have disproportionate effects on the price level therefore aggregate inflation depends on the distribution of relative price changes inflation rises when the distribution is skewed to the right and falls when the distribution is skewed to the left we show that this theoretical result explains a large fraction of movements in postwar u s inflation moreover our model suggests measures of supply shocks that perform better than traditional measures such as the relative prices of food and energy

asset pricing in partially segmented markets evidence from the finnish market this paper analyzes asset pricing in a partially segmented market where citizens of a small country are allowed to hold only their domestic securities whereas the rest of the investors foreigners are essentially allowed to hold all securities in this market setting it may occur that the citizens of the small country are willing to pay less for their domestic securities than are the foreign investors the paper derives equilibrium required rates of return for different investors in this market setting which perfectly occurred in finland and tests this equilibrium model using data from the finnish stock market empirical results are consistent with the hypotheses derived from the model several studies see e g solnik 1974a and grauer and hakansson 1987 have shown that investors should diversify internationally as by so doing they can reduce the risk of their portfolio without lowering the expected return this implies that if the citizens of a certain country are by legal restrictions prohibited from holding foreign securities they may require a higher rate of return on the domestic securities than the foreign investors do this may happen because the domestic investors cannot diversify away the specific country risk in the same way that the foreign investors can thus if we could observe the prices which the foreign and domestic investors are willing to pay for these domestic securities we would expect them to differ because of this diversification effect the finnish law prohibited finnish investors from investing in foreign securities until 1986 while simultaneously allowing foreign investors to own up to 20 of the shares of any finnish company moreover since 1984 the helsinki stock exchange hse has separately quoted the prices for the unrestricted shares which can be owned both by foreign and domestic investors and for the restricted shares owned solely by domestic investors thus the market setting depicted in the previous paragraph occurred perfectly in finland during the years 1984 and 1985 in this paper our objective is to develop and test an asset pricing model which takes into account the legal restrictions in the finnish stock market in section i we specify the market structure in the finnish stock market in more detail by explaining the relevant legal restrictions affecting the market we also present some descriptive statistics on the prices of the restricted and the unrestricted on

the contemporaneous correlation between price shocks and output shocks until the 1990s prices were believed to be procyclical several researchers have since presented evidence of counter cyclical prices this evidence proved robust but its interpretation has varied some have argued that the contemporaneous correlation between output and prices reflects both the source of the current shock and the adjustment process from short run to long run equilibrium the adjustment to the long run imparts a bias towards a negative price output correlation the issue of dynamics is addressed by estimating price shocks and output shocks the sign of the correlation between these shocks does not reveal anything about the relative importance or frequency of demand versus supply shocks however some understanding is gained from the time series of the product of the shocks in periods when the product is negative supply shocks must have been either relatively large or relatively important in periods when the product is positive demand shocks must have been either relatively large or re

partially segmented international capital markets and international capital budgeting abstract evidence suggests that international capital markets are neither fully integrated nor completely segmented there is however currently no general method available for computing the required return on corporate investments in such capital markets this paper uses a model of partially integrated international capital markets to derive optimal international capital budgeting rules we show how capital budgeting rules depend on the level of investor costs to cross border investment both directly and also indirectly through the portfolio specialization they induce we explain how required returns differ for different companies raising capital in such markets and how these costs of capital may be estimated we also explain how these differences in required returns can be consistent with general equilibrium and the effect they have on incentives for foreign direct investment

is full banking integration desirable abstract we analyze the links between banking integration and economic development for a sample of oecd countries we measure banking integration considering indicators that merge not only openness but also connectedness with other banking systems we plug these indicators into income regressions also controlling for other relevant variables considered by the literature in contrast to previous initiatives this second stage explicitly takes into account the differing levels of economic development of the countries in our sample since the benefits of enhanced banking integration might not be generalizable to this end we implement quantile regression also considering the presence of endogenous regressors results show that bank connectedness is more important for economic development than bank openness but the combined effect i e banking integration overall is positive and significant the quantile regression models used in the second stage show that the effects are stronger for the poorest economies

new evidence on the retirement and depreciation of machine tools i introduction in the late 1970s and early 1980s charles hulten and frank wykoff 1979 1981a 1981b undertook a major effort to estimate economic depreciation for the u s capital stock their pioneering work which analyzed prices for many used assets became the primary reference for estimates of economic depreciation however since then research on depreciation has been limited despite the need to examine the robustness of hulten and wykoff s results and to cover assets omitted from their studies in addition little work has been done to estimate retirement distributions which also play an important role in the construction of capital stocks this paper provides new evidence on the depreciation and retirement patterns of machine tools a grouping that includes many types of equipment that cut or form metal the data were collected from a survey of dealers belonging to the machinery dealers national association these dealers provided information on the prices of used machine tools from their own sales records they also estimated certain facets of the retirement distribution for machine tools including the average service life the direction of change in the average life since the mid 1970s and the ages by which 25 percent and 75 percent of an investment cohort are retired machine tools can be divided into two broad groups the first consists of the conventional machines that require manual control from an operator although the design and safety of these conventional machines has improved over the years the pace of technical progress has been slow the second group consists of numerically controlled machines which are more highly automated than their conventional counterparts 1 american manufacturers began to install numerically controlled machines in large numbers during the 1970s and these machines have continued to replace conventional if machines on the factory floor however at the time of my survey conventional machines still represented the bulk of machine tools operating in the united states and the estimates of depreciation and retirement in this paper refer strictly to conventional machines the paper is organized as follows section ii traces the adoption of numerically controlled machines by u s industry and then models how this phenomenon would have affected the depreciation and retirement patterns of conventional machine tools section iii briefly describes the data set section iv analyzes the information on retirement patterns provided by the dealers while section v presents the estimates of economic depreciation section vi summarizes my findings and suggests avenues for further research ii adoption of numerically controlled machines evidence and implications at roughly five year intervals since the 1920s american machinist magazine has conducted an in depth inventory of the stock of machine tools used by american manufacturers for a detailed breakdown of machine types the inventory provides information on the number of machines in use and the age distribution of this stock table i uses the american machinist surveys to characterize the adoption of numerically controlled machines in the united states since the mid 1970s as shown on the first line the share of numerically controlled machines in the total machine tool stock rose from 1 8 percent in 1976 78 to 9 2 percent in 1989 this five fold increase in the share of numerically controlled machines in the existing stock implies a considerably higher share of these machines in new investment indeed as shown in the right hand columns of the table numerically controlled machines represented 17 1 percent and 25 2 percent of all machine tools acquired during 1979 83 and 1985 89 respectively 2 thus numerically controlled machines have become a significant part of total u s investment in machine tools table i also shows that the adoption of numerically controlled machines has varied widely across machine categories

the comovement between output and prices abstract in this paper i analyze the comovement of us prices and output in the postwar period i use a new set of statistics to characterize the comovement between variables the statistics capture important information about the dynamics in the system the estimation procedure does not require assumptions about the order of integration or the types of assumptions needed for var decompositions i find that the comovement between output and prices is positive in the short run and negative in the long run i show that a model in which demand shocks dominate in the short run and supply shocks dominate in the long run can explain these empirical results while sticky price models with only demand shocks cannot

does home bias affect firm value evidence from holdings of mutual funds worldwide this study finds strong evidence that home bias affects firm valuation at both country and firm levels at the country level increasing the bias of domestic investors toward home equity lowers the market valuation of home equity at the firm level firm value increases as the compositions of local equities held by domestic and foreign investors tend toward the firms global market capitalization weights but decreases as their weights deviate from global weights overall the evidence is consistent with the optimal global risk sharing hypothesis that the greater risk sharing between domestic and foreign investors in international capital markets reduces the cost of capital and hence enhances market valuation

equilibrium exchange rate hedging we assume a world like the one that gives the capital asset pricing model but with many goods and many countries we assume that investors in a given country have homothetic utility functions with the same weights and a currency that has a sure endof period value using a price index with those weights siegel s paradox derived from jensen s inequality makes investors want a positive amount of exchange risk when average risk tolerance is the same across countries every investor will hold the same mix of market risk through the world market portfolio of all assets and exchange risk in a diversified basket of foreign currencies in fact the ratio of exchange risk to market risk is equal to the average investor s risk tolerance we can write the ratio of exchange risk to market risk and the fraction of the market s exchange risk that investors hedge as depending on an average of world market risk premia an average of world market volatilities and an average of exchange rate volatilities the weights in these averages are the same as the weights of the different countries in the currency basket given these averages the ratio and the fraction hedged will not depend directly on exchange rate means or covariances in equilibrium we can use the ratio of exchange risk to market risk to measure average risk tolerance in this model risk tolerance is observable

the cyclical behavior of prices interpreting the evidence previous studies of the cyclical behavior of prices have found that the cross correlations between output and prices in post wwii u s data are generally negative these correlations h have been interpreted as being more consistent with supply driven models of business cycle fluctuations than with models that focus on demand shocks in this paper the authors show that the signs of price output correlations provide little information about the underlying shock for instance a simple keynesian model driven by demand shocks leads to negative correlations between these variables the authors results suggest that price output correlations may not be a particularly useful way to characterize the cyclical behavior of prices copyright 1995 by ohio state university press

empirical studies of depreciation this paper surveys empirical research on depreciation based on an econometric model of asset prices introduced by hall in 1971 and shows how hall s model provides a vehicle for unifying research on constant quality price indices and depreciation an additional objective of the paper is to illustrate the use of this research in constructing an integrated system of income product and wealth accounts a system of vintage accounts like that originated by christensen and jorgenson in 1973 is the key to successful integration

home asset preference and productivity shocks abstract this paper presents sufficient conditions for the domestic investor consumer to hold in equilibrium a disproportionate share of domestic assets the analysis is carried out in a general equilibrium framework of products and assets markets when the source of the uncertainty is productivity shocks in the nontraded goods industries in the asset markets we allow trade in instruments with a payoff which is not necessarily positively correlated with the price of the consumption good as the instruments considered in the existing literature consequently in our analysis in contrast to the existing literature hedging against price uncertainty is neither necessary nor sufficient for home asset preference

are prices countercyclical evidence from the g 7 abstract this paper re examines the cyclical behavior of prices using postwar quarterly data for the g 7 we confirm recent evidence that the price level is countercyclical however we find strong evidence that the inflation rate is procyclical in our sample our results show the importance of making a clear distinction between inflation and the cyclical component of the price level when reporting and interpreting stylized facts regarding business cycles

gains from international diversification 1968 85 returns on portfolios of stocks and bonds this paper applies the multi period investment model to a universe of international securities on the basis of the simple probability assessment approach our principal findings are 1 the gains from including non u s asset categories in the universe were remarkably large in some cases statistically significant especially for the highly risk averse strategies 2 the gains from removing the no leverage constraint were more substantial than they were in the absence of non u s securities and 3 there is strong evidence of market segmentation in that the optimal levels of investment in u s securities were mostly zero in the presence of the non u s asset categories
