asymmetric effects of federal funds target rate changes on s p100 stock returns volatilities and correlations we study the effects of fomc announcements of federal funds target rate decisions on individual stock returns volatilities and correlations at the intraday level for all three characteristics we find that the stock market responds differently to positive and negative target rate surprises first the average response to positive surprises that is bad news for stocks is larger second in case of bad news the mere occurrence of a surprise matters most whereas for good news its magnitude is more important these new insights are possible due to the use of high frequency intraday data

contesting the magic of the market place black employment and business concentration in the urban context the spatial decentralisation of urban firms has been the primary focus of urbanists seeking to understand how black employment is impacted by the changing nature of business in the us very little attention has been given to the impact of market concentration on black employment in the urban environment using the most recent data available from the equal employment opportunity commission the paper finds that black male and female employment is positively associated with greater market concentration not greater market competition as predicted by some neo classical economists there is little support for the contention that economic forces at work in competitive markets tend to minimise discrimination either in the urban environment or in the nation as a whole the central city continues to be an important factor in black employment because central city firms are in industries with higher market concentration which tend to employ more black workers however increased market concentration is a crucial

testing for unbiasedness of term structure and interest differentials as predictors of future inflation changes and inflation differentials this paper argues that the unbiasedness of interest differentials as predictors of future inflation differentials and of the term structure as a predictor of future inflation changes are independent propositions the first requires rational expectations re and equality of ex ante real interest rates which holds only in the presence of uncovered interest parity uip and ex ante purchasing power parity ppp the second is correct if in addition to re the fisher hypothesis and co nstancy of ex ante real rates are satisfied the issue of the information contained in the term structure of interest rates is important because if the relationship between interest rates for different maturities could help predict future inflation the yield curve could be a guide for monetary policy fama s 1975 seminal paper found that real interest rates are constant over time with fluctuations in nominal rates mainly reflecting changes in expected inflation the so called fisher effect on the contrary mishkin 1984a rejected the constancy of real rates and the existence of a fisher effect in a number of oecd countries as for the hypothesis that interest differentials are unbiased predictors of future inflation differentials it is of interest for two main reasons first the equality of real rates which is implied would mean that monetary policy is not an effective stabilization tool in an open economy as real economic activity could not be influenced through the real interest rate second real interest rate equalization across countries requires that uip and ppp be satisfied therefore it is a test of the monetary approach to exchange rates versus models which depend on real rates differing between countries in the short run amongst previous researchers mishkin 1984b could not reject the equality hypothesis in bilateral tests of the us vis a vis six industrialized

herding on fundamental information a comparative study this paper tests for herding towards the market consensus for us and uk leading stocks and to the best of our knowledge addresses a gap in the literature regarding the importance of major fundamental macroeconomic announcements the results indicate that us investors tend to herd during days when important macro data are released and that there have been herding spill over effects from the us to the uk during earlier financial crises further results reveal more differences in herding behavior between the two markets in the us we find that investors herd due to both fundamentals and non fundamentals during different crises when in the uk there is herding only due to fundamentals and only during the dotcom bubble burst these results suggest that the drivers of herding behavior are period and country specific

efficiency effect of privatization in the developing countries privatization gained considerable momentum in the developing world in the 1980s the motives were many but the hope for higher economic efficiency underlined the expectations of the implementing governments and agencies in the developing countries while the merits of a market based economic system are well established under certain theoretical conditions far less is known of its empirical relevance in the developing world yet to the best of the author s knowledge no empirical study has examined the macro efficiency effect of privatization in the developing countries studies concerned with this issue often limit themselves to the impact of privatization at the firm level for a small number of companies and countries thus the current study is an attempt to provide a systematic quantitative measure of the magnitude of the macroeconomic effect of privatization in 45 developing countries using the concept of frontier production function efficiency differences between developing countries with differ

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

ecb monetary policy surprises identification through cojumps in interest rates this paper proposes a new econometric approach to disentangle two distinct response patterns of the yield curve to monetary policy announcements based on cojumps in intraday tick data of a short and long term interest rate we develop a day wise test that detects the occurrence of a significant policy surprise and identifies the market perceived source of the surprise the new test is applied to 133 policy announcements of the european central bank ecb in the period from 2001 2012 our main findings indicate a good predictability of ecb policy decisions and remarkably stable perceptions about the ecb s policy preferences

privatization liberalization wages and employment theory and evidence for the uk most agency based privatization models are of the owner manager relation and ignore the labour market yet in the 1980s there were profound changes in public sector and privatized firms to wages and employment we develop a bargaining model of the manager workforce relation that explains employment and wages when firms are privatized government objectives become more commercial and markets are liberalised using data on 14 uk companies 1972 1988 that were publicly owned in 1972 we find a employment fell following the change to more commercial objectives b wages were only slightly affected by this but fell if the firm lost market power

simultaneous monetary policy announcements and international stock markets response an intraday analysis abstract this paper investigates the return and volatility response of major european and us equity indices to monetary policy surprises by utilizing extensive intraday data on 5 min price quotes along with a comprehensive dataset on monetary policy decisions and macroeconomic news announcements the results indicate that the monetary policy decisions generally exert immediate and significant influence on stock index returns and volatilities in both european and the us markets the findings also show that press conferences held by the european central bank ecb that follow monetary policy decisions on the same day have a clear impact on european index return volatilities this implies that they convey additional important information to market participants overall our analysis suggests that the use of high frequency data is critical to separate the effect of monetary policy actions from those of macroeconomic news announcements on stock index returns and volatilities

roughing it up including jump components in the measurement modeling and forecasting of return volatility a rapidly growing literature has documented important improvements in financial return volatility measurement and forecasting via use of realized variation measures constructed from high frequency returns coupled with simple modeling procedures building on recent theoretical results in barndorff nielsen and shephard 2004a 2005 for related bi power variation measures the present paper provides a practical and robust framework for non parametrically measuring the jump component in asset return volatility in an application to the dm exchange rate the s p500 market index and the 30 year u s treasury bond yield we find that jumps are both highly prevalent and distinctly less persistent than the continuous sample path variation process moreover many jumps appear directly associated with specific macroeconomic news announcements separating jump from non jump movements in a simple but sophisticated volatility forecasting model we find that almost all of the predictability in daily weekly and monthly return volatilities comes from the non jump component our results thus set the stage for a number of interesting future econometric developments and important financial applications by separately modeling forecasting and pricing the continuous and jump components of the total return variation process

news announcements and price discovery in foreign exchange spot and futures markets abstract this paper studies competition in price discovery between spot and futures rates for the eur usd and jpy usd markets around scheduled macroeconomic announcements using both the information shares approach and the common factor component weight approach for futures prices from the chicago mercantile exchange cme as well as deal prices from spot trading on the electronic broking services ebs we gauge how foreign exchange spot and futures markets respond to news surprises the results show that the spot rates provide more price discovery than do the cme futures rates overall however the contribution of the futures rates to price discovery increases in the time surrounding macroeconomic announcement releases

competition and the racial wage gap evidence from brazil abstract we look at the natural experiment represented by the brazilian trade liberalization from the early 1990s to study the effect of increased competition in the market for final goods on the racial wage gap we focus on local labor markets as the unit of analysis and use the initial structure of employment to calculate the relevant tariff reduction from the perspective of each local labor market we show that the conditional racial wage gap fell more between 1991 and 2000 in regions associated with larger reductions in tariffs or in other words in regions that experienced larger increases in exposure to international competition a reduction in tariffs equivalent to the average observed in the sample was associated with a reduction in the racial wage gap of 18 our results are broadly consistent with theories of employer discrimination that predict that reductions in pure economic rents should lead to reductions in labor market discrimination

the financial and operating performance of newly privatized firms an international empirical analysis this study compares the pre and postprivatization financial and operating performance of 61 companies from 18 countries and 32 industries that experience full or partial privatization through public share offerings during the period 1961 to 1990 our results document strong performance improvements achieved surprisingly without sacrificing employment security specifically after being privatized firms increase real sales become more profitable increase their capital investment spending improve their operating efficiency and increase their work forces furthermore these companies significantly lower their debt levels and increase dividend payout finally we document significant changes in the size and composition of corporate boards of directors after privatization the last fifteen years have witnessed a significant global shift away from state socialism towards entrepreneurial capitalism one of the most important and visible aspects of this trend has been the enthusiasm with which governments of all political persuasions have sold their state owned enterprises soes to private investors in hopes that the generally unsatisfactory economic performance of these firms can be improved by the discipline of private ownership this denationalization process given its current title of privatization by the conservative government of margaret thatcher in

deutsche mark dollar volatility intraday activity patterns macroeconomic announcements and longer run dependencies this paper provides a detailed characterization of the volatility in the deutsche mark dollar foreign exchange market using an annual sample of five minute returns the approach captures the intraday activity patterns the macroeconomic announcements and the volatility persistence arch known from daily returns the different features are separately quantified and shown to account for a substantial fraction of return variability both at the intraday and daily level the implications of the results for the interpretation of the fundamental driving forces behind the volatility process is also discussed the efficient market hypothesis contends that financial asset prices provide rational assessments of fundamental values and future payoffs by implication price changes should reflect the arrival and processing of all relevant new information however the proportion of return variability that can be ascribed to public news announcements is low for example cutler poterba and summers 1989 find that even the largest daily price changes in the stock market generally cannot be associated with any significant economic news 1 moreover proxies for the flow of public information e g the number of news items released by reuter s news service berry and hiowe 1994 or dow jones company mitchell and mulherin 1994 explain little of the overall variation thus if private information is ruled out proponents of rational price formation have to assert the existence of important news items

prejudice and wages an empirical assessment of becker s the economics of discrimination we test the predictions from becker s 1957 seminal work on employer prejudice and find that relative black wages a vary negatively with the prejudice of the marginal white in a state b vary negatively with the prejudice in the lower tail of the prejudice distribution but are unaffected by the prejudice of the most prejudiced persons in a state and c vary negatively with the fraction of a state that is black our estimates suggest that one quarter of the racial wage gap is due to prejudice with nontrivial consequences for black lifetime earnings

black white earnings differentials privatization versus deregulation over 40 years ago gary becker 1957 argued that competition helps mitigate the ability of firms to engage in wage and employment discrimination deregulated transportation industries in particular provide fertile ground to test the becker hypothesis the increase in competition from deregulation should make it increasingly costly for employers to exercise discriminatory preferences several studies of the deregulated trucking industry provide support for this hypothesis nancy l rose 1987 peoples and lisa saunders 1993 john s heywood and peoples 1994 this study also utilizes information on transportation industries to test the becker hypothesis it differs from the literature in that one of the transportation industries examined is privatized 1 at question is whether the becker hypothesis also holds for a publicly owned transportation industry in a privatized environment this question is addressed by investigating privatization s effect on black white earnings differentials of public transit bus drivers these results are then compared with deregulation s effect on black white earnings differentials of private for hire truck drivers such a comparison allows for analyzing differences in differential earnings for comparable occupations in privatization and deregulation regimes i transportation industries

the impact of deregulation on the employment and wages of airline mechanics this paper describes the effects of deregulation on negotiated wage rates and employment levels of aircraft mechanics in the scheduled airline industry between 1978 and 1984 a firm by firm analysi

the benefits of privatization evidence from mexico critics of privatization often argue that its benefits come at a high cost to society the authors test the validity of this criticism for mexico s privatization program one of the world s largest case by case programs assessing the performance of newly privatized firms in such areas as profitability and efficiency they find that these firms quickly close the gap with their peers in the private sector their findings suggest that the firms profit gains come from productivity gains 52 percent layoffs 33 percent and higher prices 15 percent

how markets process information news releases and volatility we examine the impact of scheduled macroeconomic news announcements on interest rate and foreign exchange futures markets we find these announcements are responsible for most of the observed time of day and day of the week volatility patterns in these markets while the bulk of the price adjustment to a major announcement occurs within the first minute volatility remains substantially higher than normal for roughly fifteen minutes and slightly elevated for several hours nonetheless these subsequent price adjustments are basically independent of the first minute s return we identify those announcements with the greatest impact on these markets we examine the impact on interest rate and foreign exchange markets of scheduled macroeconomic news releases such as the employment report the consumer price index cpi and the producer price index ppi many market participants believe that such announcements have a major impact on financial markets indeed a small industry devoted to predicting the figures to be released in upcoming releases has evolved in recent years with the exception of the weekly money supply figures however the impact of such announcements on financial markets has received scant attention 1 this is doubly surprising given the considerable research interest in market volatility since these news releases are a potential source of much of this volatility consider for instance figure 1 as shown there prices in interest rate and foreign exchange futures markets are much more volatile between 8 30 and 8 35 a m eastern time et than during any other five minute trading period including

trucking deregulation and the black white wage gap the only previous study of the effect of product market deregulation on the black white wage gap found that this gap in the trucking industry declined after trucking deregulation in 1978 that study did not however estimate the separate effects of deregulation on union and nonunion members or on black and white drivers this study does so through an analysis of individual worker information from the march and may cps files for the years 1973 through 1988 the authors find that deregulation is associated with significantly declining black white wage gaps among both union and nonunion drivers this wage pattern is attributable to significant reductions in the real wages of white drivers the real wages of black drivers did not change with deregulation

trade liberalization and regional dynamics abstract we study the evolution of trade liberalization s effects on brazilian local labor markets regions facing larger tariff cuts experienced prolonged declines in formal sector employment and

sex discrimination and product market competition the case of the banking industry this paper examines the relationship between product market competition and employment discrimination using an especially constructed data set that links microeconomic data on female employment with measures of market concentration in the banking industry the use of firm specific data drawn from this one industry allows estimation of this relationship in a manner that avoids the problems of interindustry differences that have troubled previous studies the results provide strong support for a negative relationship between market concentration and the relative employment of women further we find that individual market shares are unrelated to female employment suggesting that the relationship is due primarily to differences across markets rather than individual firms

the real interest rate a multi country empirical study how real interest rates behave over time is critical to our understanding of many macroeconomic issues and much recent research has pursued this question very little of the research however has focused on real interest rates outside the united states this paper is an empirical exploration of real interest rate movements in seven oecd countries from 1967 ii to 1979 ii further research is needed on real rates in other countries for several reasons not only are measures of foreign real rates of interest in their ownright but extending an analysis of real rates to other countries also has the following additional benefits it can generate more powerful statistical tests of propositions previously tested on u s data and yield information on whether results found for the u s hold up in other countries this study pursues several questions that have arisen naturally from this earlier work is the hypothesis that the real rate is constant rejected when the analysis is extended to other countries does the real rate decline with increased inflation and money growth in other countries besides the united states how reliable is the fisher effect in which nominal interestrates reflect changes in expected inflation are movements in nominal interest rates a reliable indicator of movements in real rates what kind of variationsin real interest rates are there in different countries have real rates declined from the 60s to the 70s for other countries besides the u s this abstract was borrowed from another version of this item

macroeconomic news order flows and exchange rates under rational expectations and efficient markets the news contained in public information announcements is directly impounded into prices with there being no role for trades in this process of information assimilation this paper directly tests this assertion using transaction level exchange rate data and a sample of scheduled macroeconomic announcements the main result of the paper is that even information that is publicly and simultaneously released to all market participants is largely impounded into prices via the key micro level price determinant order flow we quantify the role that order flow plays and find that between a half and two thirds of price relevant information is incorporated into prices via the trading process

wall street s bailout bet market reactions to house price releases in the presence of bailout expectations abstract the rise and subsequent collapse of us house prices was one of the factors underlying the recent financial crisis one could expect that the crisis brought increased attention to the housing market and thus led to stronger market reactions to house price news we find that reactions indeed change but with a peculiar twist from september 2008 on good news from the housing market are associated with falling us stock prices and vice versa the likely explanation for which we provide cross sectional evidence is that falling house prices increased the market s trust in a government bailout thereby increasing market valuations of firms that were expected to benefit from government rescue measures

the internal economics of the firm evidence from personnel data we analyze twenty years of personnel data from one firm the hierarchical structure is quite simple and stable career movements suggest that the employee s rate of learning and the firm s learning about ability are important there are promotion fast tracks exit rates vary little with tenure or salary the firm has personnel policies like those described in the internal labor markets literature although several theoretical preconditions for ilms such as ports of entry and exit are lacking job levels are important to compensation but there is also substantial individual variation in pay within levels our companion paper in this issue explores the wage policy of this firm

the productivity effects of privatization longitudinal estimates from hungary romania russia and ukraine this paper estimates the effect of privatization on multifactor productivity using comprehensive panel data on initially state owned manufacturing firms in four economies we exploit the data s longitudinal dimension to control for preprivatization selection and estimate long run impacts the estimates are robust to functional form but sensitive to selection controls our preferred random growth estimates imply positive multifactor productivity effects of 15 percent in romania 8 percent in hungary and 2 percent in ukraine but a 3 percent effect in russia the foreign privatization effect is larger 18 35 percent in all countries positive domestic effects appear immediately in hungary romania and ukraine and continue growing thereafter but emerge only five years after privatization in russia

privatization labor and social safety nets privatization promotes economic efficiency and growth thereby reinforcing macroeconomic adjustment in the short run however it can lead to job losses and wage cuts for workers this paper discusses these adverse impacts of privatization in terms of various methods of privatization and surveys the existing empirical evidence it finds that public sales and auctions can have stronger negative effects on workers but maximize the government s revenue policymakers options for mitigating the social impact of privatization are surveyed copyright 2001 by blackwell publishers ltd

globalization and the gender wage gap there are several theoretical reasons why globalization will have a narrowing as well as widening effect on the gender wage gap but little is known about the actual impact except for a number of country studies the author provides a cross country study of the impact of globalization on the occupational gender wage gap based on the rarely used but most far ranging survey of wages around the world the international labour organization s october inquiry this annual survey was started in 1924 and contains a wealth of information on wages and the gender wage gap for the period 1983 99 there is information on the gender wage gap in 161 narrowly defined occupations in more than 80 countries around the world the author finds the following i the occupational gender wage gap appears to be narrowing with increases in gdp per capita ii there is a significantly narrowing impact of trade and foreign direct investment fdi net inflows on the occupational gender wage gap for low skill occupations both in poorer and richer countries and for high skill occupations in richer countries iii there is no evidence of a narrowing impact of trade but there is evidence of a widening impact of fdi net inflows on the high skill occupational gender wage gap in poorer countries iv wage setting institutions have a strong impact on the occupational gender wage gap in richer countries

do public ownership and lack of competition matter for wages and employment evidence from personnel records of a privatized firm do public sector firm ownership and lack of competition matter for wages and employment to address this question we consider a large public sector company that is privatized using personnel records we find employment contract liberalization to generate relative wage losses for older high tenure low skilled part time workers permanent residents and women employment reductions mostly affect the same groups experiencing a wage decline overall wage liberalization leads to an increase in wage inequality of between 6 and 9 which if applied to the whole public sector would lead to a 52 to 76 closure of the inequality gap between the private and public sectors in europe our results suggest that differences between public and private sector wage structures found in descriptive studies are to a large extent causal rather than the result of selection into these sectors and that public sector employment and career path regulations limit a firm s ability to maintain a competitive workforce

mind the gender wage gap the impact of trade and competition on sectoral wage differences this paper examines differences between women s and men s wages in 18 selected oecd countries in the period 1970 to 2005 the study is based on 12 manufacturing sector and skill specific sets of panel data on the gender wage gap we apply a system generalised method of moments gmm estimator to the extended version of the conditional gender wage gap convergence equation controlling for sector concentration and industry specific measures of openness using a difference in difference approach trade affected concentrated sectors versus trade affected competitive sectors the results indicate that i an increase in sector concentration is associated with wage gap growth ii both import and export penetration are associated with a reduction of the high skill gender wage gap growth in concentrated industries iii there is evidence of a widening impact of trade on the medium and low skill occupational gender wage gap growth in less competitive industries iv institutional regulations of the labour market have an impact on the development of the gender wage gap for highly skilled labour an increase in labour market regulation raises the growth of the gender wage gap while for medium and low skilled workers it lowers it

market perceptions of federal reserve policy and the weekly monetary announcements abstract in october 1979 the federal reserve altered its operating procedures emphasizing control of the growth rate of the money stock was the fed able to gain credibility in the market the paper investigates this question by examining the reactions of spot and expected future exchange rates foreign interest rates and long run domestic forward interest rates to the weekly federal reserve announcements of m l both before and after october 1979 the empirical evidence points out that the fed did gain credibility but was unable to establish full credibility the market reactions are consistent with the hypothesis that market participants attached a positive probability to the event that the fed may at some point in the future abandon its money stock targets

privatisation and x inefficiency a bargaining approach the usual analysis of privatization and x inefficiency uses agency theory to model managerial effort the authors model worker effort as determined by a bargain between firms and workers workers dislike effort because it lowers utility firms prefer high effort because it raises productivity public sector firms are assumed to be social welfare maximizers and therefore compared to private sector firms they bargain lower effort levels since they have the interests of consumers and workers at heart the authors model predicts that under certain conditions privatization should raise effort and so lower x inefficiency and that wages may increase or decrease copyright 1995 by blackwell publishing ltd

the impact of economic news on bond prices evidence from the mts platform although there is an extensive literature on the impact of macroeconomic announcements on asset prices the bond market has received less attention than the foreign exchange and equity markets even less if we consider the european market this paper uses high frequency intra day data over a three year period to investigate the impact of regularly scheduled macroeconomic news and monetary policy announcements on the returns of the italian government bond market the largest one in the euro zone with respect to the previous papers we use a much broader set of announcements sixty eight and a relatively novel dataset mts we find that twenty five news have a significant impact on bond returns and that almost all announcements are incorporated into prices within twenty minutes from the release

intraday jumps and us macroeconomic news announcements this paper applies recent non parametric intraday jump detection procedures to investigate the presence and importance of intraday jumps in us futures markets more importantly the paper investigates the extent to which statistically significant intraday jumps are associated with us macroeconomic news announcements jumps are prevalent large and contribute heavily to total daily price variation approximately one third of jumps correspond to us macroeconomic news announcements with pure announcement effects causing large increases in the absolute sizes of jumps and the informational surprise of the announcement explaining large proportions of the jumps the statistical and economic significance of news related jumps is confirmed by results that show higher volatility persistence predictability of lower frequency returns larger effects on microstructure variables jump clustering and co jumps from these jumps versus non news related jumps although there are some interesting variations across asset classes

some evidence on the international inequality of real interest rates abstract this paper undertakes econometric tests of the hypothesis that ex ante real interest rates are equal across countries with highly integrated capital markets the issue is of practical importance because the violation of real rate equality is a necessary condition for monetary policy to influence the open economy through the real interest rate channel although an empirical literature concerning real rate equality already exists previous investigators have focused on pre tax real rates this paper contributes to the literature by attempting to incorporate the effects of taxation into the analysis

using propensity matching estimators to evaluate the impact of privatization on wages whether the transfer of ownership rights to the private sector leads to a decline or increase in wage growth is theoretically ambiguous given that the outcome depends on the uncertain interaction between firms and workers using propensity matching techniques this article investigates the effects of privatization on wages in the portuguese banking industry the empirical results obtained from quadros de pessoal for the period between 1989 and 1997 generally show a negative positive short run long run effect of privatization on relative wage growth for both men and women retained in the privatized firms moreover the results show that the most educated and experienced oldest workers as well as those in the high skill occupational categories were more likely to experience a negative wage effect

speed algorithmic trading and market quality around macroeconomic news announcements this paper documents that speed is crucially important for high frequency trading strategies based on u s macroeconomic news releases using order level data on the highly liquid s p 500 etf traded on nasdaq from january 6 2009 to december 12 2011 we find that a delay of 300 ms or more significantly reduces returns of news based trading strategies this reduction is greater for high impact news and on days with high volatility in addition we assess the effect of algorithmic trading on market quality around macroeconomic news in the minute following a macroeconomic news arrival algorithmic activity increases trading volume and depth at the best quotes but also increases volatility and leads to a drop in overall depth quoted half spreads decrease increase when we measure algorithmic trading over the full top of the order book

is there less discrimination in occupations where recruitment is difficult the authors empirically test the cross sectional relationship between hiring discrimination and labor market tightness at the level of the occupation to this end they conduct a correspondence tes

enjoying the quiet life corporate governance and managerial preferences much of our understanding of corporations builds on the idea that managers when they are not closely monitored will pursue goals that are not in shareholders interests but what goals would managers pursue this paper uses variation in corporate governance generated by state adoption of antitakeover laws to empirically map out managerial preferences we use plant level data and exploit a unique feature of corporate law that allows us to deal with possible biases associated with the timing of the laws we find that when managers are insulated from takeovers worker wages especially those of white collar workers rise the destruction of old plants falls but the creation of new plants also falls finally overall productivity and profitability decline in response to these laws our results suggest that active empire building may not be the norm and that managers may instead prefer to enjoy the quiet life

jumps in financial markets a new nonparametric test and jump dynamics this paper introduces a new nonparametric test to detect jump arrival times and realized jump sizes in asset prices up to the intra day level we demonstrate that the likelihood of misclassiflcation of jumps becomes negligible when we use high frequency returns using our test we examine jump dynamics and their distributions in the u s equity markets the results show that individual stock jumps are associated with prescheduled earnings announcements and other company speciflc news events additionally s p 500 index jumps are associated with general market news announcements this suggests difierent pricing models for individual equity options versus index op

substitution and dropout bias in social experiments a study of an influential social experiment this paper considers the interpretation of evidence from social experiments when persons randomized out of a program being evaluated have good substitutes for it and when persons randomized into a program drop out to pursue better alternatives using data from an experimental evaluation of a classroom training program we document the empirical importance of control group substitution and treatment group dropping out evidence that one program is ineffective relative to close substitutes is not evidence that the type of service provided by all of the programs is ineffective although that is the way experimental evidence is often interpreted

explaining wage inequality in telecommunications services customer segmentation human resource practices and union decline this study examines factors related to within occupation wage inequality among service and sales workers in the telecommunications industry the author draws on a 1998 survey of a nationally representative sample of 354 service and sales centers in the industry to examine the importance of management practices and union institutions in shaping wage variation the results strongly indicate that business strategies of customer segmentation and human resource practices explain variation in wages over and above that explained by the human capital of the work force in addition despite extensive deregulation and de unionization of the industry the union wage premium is 22

the statistical and economic role of jumps in continuous time interest rate models this paper analyzes the role of jumps in continuous time short rate models i first develop a test to detect jump induced misspecification and using treasury bill rates find evidence for the presence of jumps second i specify and estimate a nonparametric jump diffusion model results indicate that jumps play an important statistical role estimates of jump times and sizes indicate that unexpected news about the macroeconomy generates the jumps finally i investigate the pricing implications of jumps jumps generally have a minor impact on yields but they are important for pricing interest rate options

the high frequency response of exchange rates to monetary policy actions and statements abstract this paper investigates the impact of us monetary policy on the level and volatility of exchange rates using an event study with intraday data for five currencies the us dollar exchange rate versus the euro the canadian dollar the british pound the swiss franc and the japanese yen i construct two indicators of news about monetary policy stemming separately from policy decisions and from balance of risk statements estimation results show that both policy decisions and communication have economically large and highly significant effects on the exchange rates with the surprise component of statements accounting for most of the explainable variation in exchange rate returns in response to monetary policy this paper also shows that exchange rates tend to absorb fomc monetary surprises within 30 40 min from the announcement release
