online and official price indexes measuring argentina s inflation abstract prices collected from online retailers can be used to construct daily price indexes that complement official statistics this paper studies their ability to match official inflation estimates in five latin american countries with a focus on argentina where official statistics have been heavily criticized in recent years the data were collected between october 2007 and march 2011 from the largest supermarket in each country in brazil chile colombia and venezuela online price indexes approximate both the level and main dynamics of official inflation by contrast argentina s online inflation rate is nearly three times higher than the official estimate

decomposing productivity growth in the u s computer industry in this paper we examine the sources of the productivity growth in the u s computer industry from 1978 to 1999 we estimate a joint production model of output quantity and quality that distinguishes two types of technological changes process and product innovations based on the estimation results we decompose total factor productivity tfp growth rate into the contributions of process and product innova tions and scale economies we find that product innovation associated with better quality accounts for about 30 of the tfp growth in the computer industry furthermore the tfp acceleration in the computer industry in the late 1990s is mainly derived from a rapid increase in product innovation

can falling supply explain the rising return to college for younger men a cohort based analysis although the college high school wage gap for younger u s men has doubled over the past 30 years the gap for older men has remained nearly constant in the united kingdom and canada the college high school wage gap also increased for younger relative to older men using a model with imperfect substitution between similarly educated workers in different age groups we argue that these shifts reflect changes in the relative supply of highly educated workers across age groups the driving force behind these changes is the slowdown in the rate of growth of educational attainment that began with cohorts born in the early 1950s in all three countries

the demand for energy cross country evidence using the florida model abstract income and own price elasticities of demand for energy for 51 countries in 1980 are presented based on pooled estimates from an 11 good demand system estimated with the florida model results indicate income elasticities of demand for energy are significantly larger than unitary for all countries and own price elasticities of demand for energy range between 0 8 and 1 0

the demand for energy evidence from a cross country demand system abstract some new evidence on the income own price elasticities of demand for energy consumption by consumers is presented estimates are derived from a complete system of cross country demand equations with energy being one of the commodities considered

costly arbitrage evidence from closed end funds arbitrage costs lead to large deviations of prices from fundamentals using a sample of closed end funds i find that the market value of a fund is more likely to deviate from the value of its assets 1 for funds with portfolios that are difficult to replicate 2 for funds that pay out smaller dividends 3 for funds with lower market values and 4 when interest rates are high these factors are related to the magnitude of the deviation as opposed to the direction i e whether discount or premium and explain a quarter of cross sectional mispricing variation these findings are consistent with noise trader models of asset pricing

engel s law diet diversity and the quality of food consumption increasing income brings about a decline in the relative importance of food consumption a wider spread of spending patterns and a demand for higher quality goods using an index number approach this article analyzes these three closely related tendencies stripping out the impact of prices from the dispersion of food expenditures gives a volume based measure of diet diversity that is relevant for nutrition using unpublished data from the world bank s international comparison program for 31 items of food in more than 150 countries we find that diets of rich countries are substantially more diverse than those of the poor and that volumes are the more appropriate way to measure the inequality of diversity the quality of the food basket based on the luxury necessity distinction of consumption increases with income but the elasticity is small there is a modest tendency for the structure of prices to be regressive since prices of luxuries relative to necessities are lower in richer countries additionally our diversity and quality measures are shown to have implications for demand analysis and well being

computing productivity firm level evidence we explore the effect of computerization on productivity and output growth using data from 527 large us firms over 1987 1994 we find that computerization makes a contribution to measured productivity and output growth in the short term using one year differences that is consistent with normal returns to computer investments however the productivity and output contributions associated with computerization are up to five times greater over long periods using five to seven year differences the results suggest that the observed contribution of computerization is accompanied by relatively large and time consuming investments in complementary inputs such as organizational capital that may be omitted in conventional calculations of productivity the large long run contribution of computers and their associated complements that we uncover may partially explain the subsequent investment surge in computers in the late 1990s

changes in returns to education in latin america the role of demand and supply of skills using micro data for the urban areas of argentina brazil chile colombia and mexico the authors document trends in men s returns to education during the 1980s and the 1990s and estimate the role of supply and demand factors in explaining the changes in skill premia they propose a model of demand for skills with three production inputs corresponding to workers with primary secondary and university level education further the authors demonstrate that an unprecedented rise in the supply of workers having completed secondary level education depressed their wages relative to workers with primary level education throughout latin america this supply shift was compounded by a generalized shift in the demand for workers with tertiary education

management ownership and market valuation an empirical analysis we investigate the relationship between management ownership and market valuation of the firm as measured by tobin s q in a 1980 cross section of 371 fortune 500 firms we find evidence of a significant nonmonotonic relationship tobin s q first increases then declines and finally rises slightly as ownership by the board of directors rises for older firms there is evidence that q is lower when the firm is run by a member of the founding family than when it is run by an officer unrelated to the founder

creative destruction and firm specific performance heterogeneity traditional u s industries with higher firm specific stock return and fundamentals performance heterogeneity use information technology it more intensively and post faster productivity growth in the late 20 th century we argue that this mechanically reflects a wave of schumpeter s 1912 creative destruction disrupting a wide swath of industries with successful it adopters unpredictably undermining established firms this validates endogenous growth theory models of creative destruction e g aghion and howitt 1992 and suggests intensified creative destruction as explaining findings associating greater firm specific performance variation with higher per capita gdps economy growth rates accounting standards financial system development and property right protection

does the form of compensation matter abstract the role of fee contracts in the agency relation between investment bankers and client firms in tender offers is investigated using a sample of offers between 1978 and 1986 different fees have different payoff functions which can be used by firms to create incentives and by bankers to signal differences in abilities the effectiveness of fee contracts in resolving agency problems in tested with mixed results the evidence suggests that fee contracts are used as a tool by both firms and bankers and that contracts influence tender offer outcomes but that contracting is only a partial solution to the agency problem

an empirical examination of the relation between debt contracts and management incentives abstract prior research on the factors influencing the use of debt covenants restricting dividends and additional borrowing is extended by considering management incentives when alternative incentive variables are considered separately we find covenants have a significant negative relation to ceo cash compensation an insignificant relation to the value of ceo equity held and significant positive relations to both the ratio of the value of ceo equity holdings to cash compensation and the fraction of equity held by the ceo in two stage simultaneous equations models only the latter is significant when jointly considered with each of the other incentive variables

agency relationships in family firms theory and evidence does owner management necessarily eliminate the agency costs of ownership drawing on agency literature and on the economic theory of the household we argue that private ownership and owner management expose privately held owner managed firms to agency threats ignored by jensen s and meckling s 1976 agency model private ownership and owner management not only reduce the effectiveness of external control mechanisms they also expose firms to a self control problem created by incentives that cause owners to take actions which harm themselves as well as those around them jensen 1994 p 43 thus shareholders have incentive to invest resources in curbing both managerialand owner opportunism we extend this thesis to the domain of the family firm after developing hypotheses which describe how family dynamics and specifically altruism exacerbate agency problems experienced by these privately held owner managed firms we use data obtained from a large scale survey of family businesses to field test our hypotheses and find evidence which suggests support for our proposed theory finally we discuss the implications of our theory for research on family and other types of privately held owner managed firms

alternative mechanisms for corporate control we examine performance and management characteristics of fortune 500 firms experiencing one of three types of control change internally precipitated management turnover hostile takeover and friendly takeover we find that firms experiencing internally precipitated management turnover perform poorly relative to other firms in their industries but are not concentrated in poorly performing industries in contrast targets of hostile takeovers are concentrated in troubled industries there is also weaker evidence that hostile takeover targets underperform their industry peers we interpret this evidence as consistent with the idea that the board of directors is capable of firing managers whose leadership leads to poor performance relative to industry but that an external challenge in the form of a hostile takeover is often required when the whole industry is in decline the evidence also indicates that firms run by a member of the founding family are less likely to experience either internally precipitated top management turnover or a hostile takeover on the other hand firms whose top management team is dominated by a single relatively young top executive while lacking in internal discipline are more likely to experience a hostile takeover this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item

the changing demand for energy in rich and poor countries over 25 years abstract country specific income and own price elasticities of demand for private consumption of energy are compared across time and affluence for 43 countries that participated in the 1980 1996 and 2005 international comparison program based on estimates from a ten good demand system results indicate that income elasticities of demand for energy are significantly larger than unitary in 1980 are approximately unitary in 1996 but become inelastic for all 43 countries in 2005 own price elasticities decrease absolutely going from 1980 to 1996 to 2005 ranging from 0 8 to 1 0 in 1980 0 7 to 0 8 in 1996 and 0 6 to 0 7 in 2005 elasticity estimates are also calculated for the set of countries in 1996 and 2005 that do not participate in the icp in 1980

technological change and the stock market tobin s average q has usually been well above 1 but fell below 1 during 1974 1984 our model explains this pattern and reconciles it with unchanging aggregate investment the stock market value in the numerator of q reflects ownership of physical capital and knowledge but the denominator measures just physical capital therefore q is usually above 1 periodic arrivals of important new technologies such as the microprocessor in the 1970 s suddenly render old knowledge and capital obsolete causing the stock market to drop national accounts measures of physical capital miss this rapid obsolescence then q appears to drop below 1 jel e44 o3 o41

negotiated block trades and corporate control we identify negotiated trades of large percentage blocks of stock as corporate control transactions when a block trades and the firm is not fully acquired cumulative abnormal returns average 5 6 and 33 of the chief executives are replaced within a year stock price increases are larger when control passes to the new blockholder when management does not resist the blockholder s effort to influence corporate policy and when the block purchaser eventually fully acquires the firm these findings suggest that the specific skills and expertise of blockholders and not just the concentration of ownership are important determinants of firm value we examine 106 negotiated trades of at least 5 of the common stock of new york stock exchange nyse and american stock exchange amex listed corporations our primary objective is to assess the impact of these transactions on the firms whose shares are traded we also investigate the importance of active block investor s specific managerial expertise and incentives for firm value the emerging literature on concentrated ownership focuses on how the level of ownership affects a blockholder s incentives to undertake a variety of corporate decisions although it has been recognized that a blockholder s identity also can be important less attention has been paid to this issue several recent studies however provide evidence that blockholders incentives and expertise are not homogeneous for example holderness and sheehan 1985 find that the stock market reacts more favorably to initial block accumulations by six controversial investors who are often portrayed in the press as raiders than to initial accumulations by a random sample of investors morck shleifer and vishny 1988 find that firm value tends to be lower when the firm is run by a member of the founder s family than when it is run by an officer unrelated to the founder brickley lease and smith 1988 document that institutional blockholders are less willing to vote against management on antitakeover amendments when they are likely to have business dealings with the firm when a block trades the concentration of ownership typically does not change but the blockholder s identity does

cross sectoral variation in the volatility of plant level idiosyncratic shocks we estimate the volatility of plant level idiosyncratic shocks in u s manufacturing we measure the variation in revenue total factor productivity not explained by either industry or economy wide factors or by establishments characteristics we find that idiosyncratic shocks are much larger than aggregate shocks accounting for about 80 of the overall uncertainty faced by plants plants in the most volatile sector are subject to about six times as much idiosyncratic uncertainty as plants in the least volatile we provide evidence suggesting that idiosyncratic risk is higher in industries where the extent of creative destruction is likely to be greater

south korean chaebols and value based management south korean industrial conglomerates chaebols are discussed in the context of value based management vbm recent economics and finance literature on the diversion of corporate resources from the firm to the controlling shareholders tunneling for which chaebols are notoriously known is discussed chaebols have engaged in empire building and expropriation of minority shareholders distorting the process of efficient resource allocation in south korea and became the root cause of the 1997 financial crisis we argue that the 1997 crisis should be viewed as a consequence of chaebols systematic deviation from the guiding principles of vbm we use tunneling within chaebols as an example of the need to directly address prohibition of the expropriation of minority shareholders as a primary postulate of vbm we argue that vbm should require that the value generated by the firm not be expropriated from minorities or any stakeholders by dominant shareholders we also examine moral and ethical considerations and present explanations as to why the unethical practice of tunneling has been tolerated by the south korean public we show that public opinion on tunneling is changing and that the treatment of minority shareholders by chaebols controlling families is becoming increasingly unacceptable to south koreans

the asymmetric relationship between executive earnings management and compensation a panel threshold regression approach abstractprior research shows that chief executive officers ceos are rewarded for their earnings management we re examine this issue using a panel threshold regression approach which allows the effect of earnings management on the ceo compensation to change across the level of earnings management and ceo compensation our results show that the effect of ceos discretionary accounting choices on their compensation is not homogeneous across various degrees of earnings management and compensation in particular for firms with moderate inordinate levels of earnings management and ceo compensation earnings management is rewarded penalized

founders heirs and corporate opacity in the united states abstract we argue that information about firm activities can vary substantially in the presence of founder or heir ownership thereby influencing the risks borne by minority investors we explore two hypotheses with regard to these controlling shareholders and corporate transparency focusing on their role as monitor in place and their potential to exploit firm opacity to accrue private benefits of control to test these notions we create an opacity index that ranks the relative transparency of the two thousand largest industrial us firms and find founder and heir ownership in 22 and 25 of these firms respectively our analysis indicates that in large publicly traded companies both founder and heir firms are significantly more opaque than diffuse shareholder firms we also find that founder and heir controlled firms exhibit a negative relation to performance in all but the most transparent firms surprisingly additional tests reveal that concerns about divergences in ownership versus control management type dual class shares and board influence appear to be substantially less important than corporate opacity in explaining the performance impacts of founder and heir control finally we decompose corporate opacity into disclosure and market scrutiny components finding that the disclosure quality component appears to be of greater importance to investors however irrespective of whether these controlling shareholders create or stay in the firm because of corporate opacity our analysis suggests that founders and heirs in large publicly traded firms exploit opacity to extract private benefits at the expense of minority investors

skill premium labor supply and changes in the structure of wages in latin america earnings inequality declined rapidly in argentina brazil and chile during the 2000s a reduction in the experience premium is a fundamental driver of declines in upper tail 90 50 inequality while a decline in the education premium is the primary determinant of the evolution of lower tail 50 10 inequality relative labor supply is important for explaining changes in the skill premiums relative demand trends favored high skilled workers during the 1990s shifting in favor of low skilled workers during the 2000s changes in the minimum wage and more importantly commodity led terms of trade improvements are key factors behind these relative skill demand trends

why company specific risk changes over time company specific risk climbed steadily between 1962 and 1999 in the u s market but fell sharply between 2000 and 2003 this article explores the hypothesis that three factors are primarily responsible for observed changes in company specific risk changes in the market weights of riskier industries changes in the relative role of small capitalization stocks in the market and measurement error associated with changes in within industry concentration empirical tests reveal that each factor contributes to changes in company specific risk over time and that combined these three factors largely explain changes in company specific risk over the past 40 years

affluence and food a simple way to infer incomes accurate and timely measures of cross country real incomes are still a rarity as the share of expenditure devoted to food is readily available we use engel s law in reciprocal form to measure affluence analysis of real income data for over 100 countries indicates that this approach is viable to recognize the role of uncertainty in the analysis we present the results in the form of stochastic cross country income comparisons

earnings and management incentives comments abstract in the preceding papers pourciau murphy and zimmerman and clinch and magliolo address the role of earnings in evaluating ceo performance for dismissal or compensation decisions and the implications for earnings management this comment evaluates the three papers and suggests avenues for future research into the stewardship role of accounting data and opportunistic financial reporting behavior

the investment opportunity set and accounting procedure choice abstract this paper provides evidence on the cross sectional relation between firms investment opportunities their debt and compensation contracts their size and financial leverage and their accounting procedure choices this evidence is important because previous studies hypothesize that the link between firms investment opportunities and their accounting choices helps explain extant results on the size debt equity and bonus plan hypotheses however while i find that firms investment opportunities do affect the nature of their contracts i also find that the traditional explanations for accounting choice are important after controlling for the effects of the investment opportunity set

the agency problems embedded in firm s equity investment we find that agency problems are embedded in firm s excess and abnormal equity investments that are mainly dictated by controlling shareholder s motives and ethical choices manifested in ownership and board structure the excess equity investment is gauged with respect to industry average the abnormal equity investment is specifically referred to the number of nominal investment companies that are fully controlled by the controlling owners while subject to little governance our empirical evidences of 345 taiwanese non financial listed firms show that firm s excess and abnormal equity investments are negatively correlated with controlling shareholder s cash flow rights while are positively correlated with the control cash flow deviation and board affiliation the results are supportive of the positive incentive hypothesis and the negative entrenchment hypothesis put forth by la porta et al 2002 journal of finance57 1147 1171 and claessen et al 2002 journal of finance57 2741 2742 the negative relation between equity investment and firm s value further supports the agency postulation that corporate excess and abnormal equity investments represent a leeway for controlling shareholder to exploit wealth of minority shareholders this study potentially contributes to the literature of business ethics by portraying an empirically testable linkage from controlling owner s ethical choices to his actions and therefore firm s value

the energy gdp relationship in developing countries empirical evidence and stability tests abstract the elasticity of energy consumption with respect to gdp is an important element in projecting energy needs in economic development this study uses cross section and pooled cross section time series data to find that the elasticity of energy consumption with respect to gdp in developing countries is in the neighbourhood of 1 35 and significantly above one over the period covered 1970 to 1976 the relationships appear to have remained stable there are significant differences between areas of the world but the differences in the elasticities between different continents are not large

ownership and firm innovation in a transition economy evidence from china we examine innovation performance of firms in a transition economy from an ownership perspective we focus specifically on the relationship between ownership structures and firm innovation performance drawing on data from 548 chinese firms we find volume of patent registration to be most strongly influenced by foreign ownership in the firm along with firm affiliation within a business group the influence of state and institutional ownership on innovation performance is positive but lagged contrary to expectations insider ownership leads to lower innovation performance and concentrated ownership has no significant impact our study has two principal contributions firstly we utilize a comprehensive treatment of ownership characteristics overcoming weakness in previous studies that have used a more narrow focus on ownership type secondly we contribute to understanding of how firms in transition economies build indigenous capabilities for innovation by drawing attention to the interplay of foreign and domestic control of agents innovation

energy consumption and economic activity in industrialized economies a note abstract in industrialized countries the income elasticity of primary energy demand is not far off unity furthermore it can be argued that there is little use in distinguishing between short and long term income elasticities a long term income elasticity does not have a direct impact on energy demand and hence it is of doubtful use in energy demand projections via an aggregate oecd model it was estimated that the short term impact of prices on primary energy demand is about 0 15 while the long term impact is 0 43 but increasing over time

does best practice in setting executive pay in the uk encourage good behaviour we examine how uk listed companies set executive pay reviewing the implications of following best practice in corporate governance and examining how this can conflict with what shareholders and other stakeholders might perceive as good behaviour we do this by considering current governance regulation in the light of interviews with protagonists in the debate setting out the dilemmas faced by remuneration setters and showing how the processes they follow can lead to ethical conflicts

latin america s social policy challenge education social insurance redistribution abstract long regarded as a region beset by macroeconomic instability high inflation and excessive poverty and inequality latin america has undergone a major transformation over the last 20 years the region has seen improved macroeconomic management and substantial and sustained reductions in poverty and inequality in this paper we argue that social policy including human capital and education social insurance and redistribution need special attention if achievements of the last two decades are to be sustained and amplified starting in the mid 1990s many governments in the region introduced a variety of programs including noncontributory pensions and health insurance and cash transfers targeted to the poor social spending in latin america increased sharply these policies have been widely praised and we believe they have resulted in substantial improvements in the lives of the poor in the region however a more nuanced view shows some worrisome trends moving forward we believe it is nec

managerial ownership of voting rights abstract managers of firms with dual classes of common stock can choose different quantities of votes for a given cash flow interest by choosing different quantities of the two securities we study managerial stock holdings in 45 dual class firms and find that vote ownership per se is an important motivation for these holdings in that corporate officers and their families hold a median 56 9 of the votes and 24 0 of the common stock cash flows we also find significant family involvement in many sample firms and document four case studies in which explicit acquisition premiums were paid for superior voting shares

the impact of idiosyncratic uncertainty when investment opportunities are endogenous this paper develops a general equilibrium model to study the impact of aggregate fluctuations in idiosyncratic volatility that incorporates the endogenous determination of investment opportunities by making investment options more valuable an increase in volatility encourages the creation of new investment options i find the response of the economy to a volatility shock depends on how investment opportunities are obtained if potential entrants are allowed to invest in new idiosyncratic technologies thereby acquiring options for further investment the volatility shock increases overall investment and results in an economic boom on the other hand if such an investment in option creation is precluded and investment opportunities are exogenously given the volatility shock decreases aggregate investment

diverging trends in aggregate and firm volatility this note documents the diverging trends in volatility of the growth rate of sales at the aggregate and firm levels we establish that the upward trend in firm volatility is not simply driven by a compositional bias in the sample studied we argue that this new fact brings into question the proposed explanations for the decline in aggregate volatility and that given the symmetry of the diverging trends at the micro and macro levels a common explanation is likely we conclude by describing one such theory

testing agency theory with entrepreneur effort and wealth we develop a principal agent model in an entrepreneurial setting and test the model s predictions using unique data on entrepreneurial effort and wealth in privately held firms accounting for unobserved firm heterogeneity using instrumental variables techniques we find that entrepreneurial ownership shares increase with outside wealth and decrease with firm risk effort increases with ownership and effort increases firm performance the magnitude of the effects in the cross section of firms suggests that agency costs may help explain why entrepreneurs concentrate large fractions of their wealth in firm equity

q and the tax bias theory abstract a growing body of literature analyzes the variation in q the ratio of financial market value to asset current replacement cost and makes inferences about attributes such as monopoly power profitability managerial performance etc these studies ignore potential biases embedded in q that result from non neutral tax policies this study examines the association between q and tax biases and establishes that differences in accumulated depreciation tax shields explain significant variation in q the implication that q should be adjusted for tax biases before use in empirical research is examined further adjusting q for tax biases at least with the factors herein leads only to minor changes in econometric analyses

empirical age earnings profiles the human capital earnings function in which earnings are expressed as a quadratic in potential experience is probably the most widely accepted empirical specification in economics in spite of its widespread acceptance the human capital earnings function provides a very poor approximation of the true empirical relationship between earnings and experience the standard formulation understates early career earnings growth by about 30 50 and overstates midcareer growth by 20 50 however simple alternative specifications that fit the data are available

computers productivity and input substitution i introduction the last two decades has been a puzzling time for many productivity analysts while computer prices fell at extraordinary rates and firms invested hundreds of billions of dollars in new computer equipment aggregate productivity growth remained sluggish this computer productivity paradox has generated a large literature that examines the economic impact of the computer revolution 1 this paper offers a simple solution to the computer productivity paradox by making careful distinction between computers as an output from one sector and an input to other sectors data for 35 manufacturing and service sectors for 1947 1991 show that sectoral differences are crucial in understanding the impact of computers aggregate analysis is inappropriate since it obscures basic distinctions between a shifting production function in the computer producing sector multi factor productivity growth and movements along production functions in the computer using sectors substitution and capital accumulation once these differences are isolated the growth impact of computers is readily observable the computer producing sector experienced fundamental technological progress and now produces cheaper better computers the sectoral data show this as rapid multi factor productivity mfp growth for 1973 1991 although aggregate mfp growth remains below historic averages the computer producing sector has clearly done its part mfp growth in this sector is many times the economy average and has contributed over one third of aggregate mfp growth for 19811991 the sectoral detail shows that the slowdown in aggregate productivity would have been much more severe were it not for such large mfp gains in the computer producing sector for the other sectors of the economy computers affect growth in a more traditional although less glamorous way when the price of real computing power fell so dramatically in the 1970s and 1980s firms responded by substituting away from relatively expensive labor and non computer capital and investing heavily in cheap computers for these sectors the computer revolution affects output growth not by raising mfp but by inducing firms to accumulate computers at extraordinary rates real computer services for example grew in excess of 20 per year in 14 out of 35 sectors for 1973 1991 although virtually all sectors are rapidly accumulating computer equipment computers remain small in levels in 1991 for example computer investment was only 10 of private fixed investment so the growth contribution of computers remains small relative to sectoral aggregates of labor and non computer capital the rapid rates of accumulation however are clearly making computers a more important source of growth across sectors with this heavy investment also came the wide spread expectation that computers would fundamentally alter the way firms operate and lead to higher mfp the reality has been very different as the most computer intensive sectors show steep declines in mfp growth after 1973 with three quarters of all computers concentrated in three service sectors trade fire and other services however this finding must be interpreted with caution as griliches 1994 notes output in these sectors is largely unmeasurable and thus mfp growth will be understated nonetheless it is quite reasonable that even computer using sectors where output is easier to measure show no mfp gains computer investment creates a capital input that enters the production function like any other purchased input since constant quality deflators embody productivity improvements in investment the direct impact is seen through the rapid capital accumulation only if the adoption of computers leads to production externalities or spillovers would computer investment also increase mfp growth the data however show no evidence of this ii computers and growth the national statistics most clearly show the computer revolution in the investment data

comovement information production and the business cycle abstract recent theoretical research suggests that information production is a positive externality of aggregate economic activity veldkamp 2005 both the quantity and quality of information increase during periods of economic expansion and decrease during periods of contraction based on this insight we hypothesize and confirm that time varying information production drives the comovement patterns observed in stock returns we examine stock return comovement in 36 countries from 1980 to 2007 and show that consistent with the theory comovement patterns are countercyclical that is when information production is high low comovement is low high we also find that the relation between comovement and the business cycle is stronger in countries that experience large intertemporal swings in information production finally we show that the relation between business cycle and comovement is stronger in poor countries countries with less developed financial markets and countries with weaker accounting and transparency standards these results suggest that financial development and transparency are conducive to a steady flow of financial information over the business cycle

efficiency and the bear short sales and markets around the world we analyze cross sectional and time series information from 46 equity markets around the world to consider whether short sales restrictions affect the efficiency of the market and the distributional characteristics of returns to individual stocks and market indices we find some evidence that prices incorporate negative information faster in countries where short sales are allowed and practiced a common conjecture by regulators is that short sales restrictions can reduce the relative severity of a market panic we find strong evidence that in markets where short selling is either prohibited or not practiced market returns display significantly less negative skewness

the information technology revolution and the stock market evidence since 1968 the ratio of stock market capitalization to gdp has varied by a factor of 5 in 1972 the ratio stood at above unity but by 1974 it had fallen to 0 45 where it stayed for the next decade it then began a steady climb and today it stands above 2 we argue that the it revolution was behind this and moreover that the capitalization gdp ratio is likely to decline and then rise after any major technological shift the three assumptions that deliver the result are

the performance of privatized firms in the czech republic abstract with the growing importance of privatizations as a part of government policy most empirical studies of these privatizations conclude that firm performance immediately improves following privatization privatization has been the most important part of the transition from the centrally planned economies of central and eastern europe and has a larger impact on those economies than privatizations in other countries however few studies have looked at the performance of firms following mass privatization this study uses 453 separate firms 101 firms privatized in both waves for a total of 554 observations in the first and second waves of czech voucher privatization using methodology from previous studies we find that while the overall effects from privatization are positive the effects vary by privatization wave size and industry firms privatized in the first wave performed worse decline in performance following privatization than firms privatized in the second wave we also fail to find ownership concentration or debt as an important factor in restructuring the firm i believe that the results are consistent with two hypotheses first economic and political structure surrounding the privatization waves plays an important part in the success of privatization stable environments both political and economic help privatized firms restructure and improve operating performance as well as attract foreign investors and capital even in less developed countries but in transitional economies undergoing mass privatization in rapidly changing and developing economic and political environments hinder firms from restructuring and improving performance following privatization results are also consistent with the hypothesis that firms with a longer preparation period prior to privatization an implicit seasoning improve performance following privatization

new empirical evidence on the bid ask spread in this article we model the determinants of spread for 734 firms listed on the nyse over the period 1 january 1998 to 31 december 2008 we propose a panel data model of the determinants of spread there are four main messages emerging from our work we find a statistically significant effect of volume on spread inconsistent with the work of johnson 2008 on price we find mixed results consistent with the literature on the effect of price volatility on spread our results are completely the opposite of the cross sectional literature but sides with the relatively recent work of chordia et al 2001 we allow for persistence of spread as a determinant of spread and find significant evidence of spread persistence across all 16 sectors finally we examine size effects and find statistically strong evidence of size effects based on the relationship between price and spread persistence and spread and volatility and spread

finance and the sources of growth the authors evaluate whether the level of development in the banking sector exerts a causal impact on economic growth and its sources total factor productivity growth physical capital accumulation and private saving they use 1 a pure cross country instrumental variable estimator to extract the exogenous component of banking development and 2 a new panel technique that controls for country specific effects and endogeneity they find that banks do exert a large causal impact on total factor productivity growth which feeds through to overall gdp gross domestic product growth the long run links between banking development and both capital growth and private savings are more tenuous

recent trends in income inequality in latin america this paper documents patterns and recent developments on income inequality in latin america la new comparative international evidence confirms that la is a region of high inequality although maybe not the highest in the world income inequality has fallen in the 2000s suggesting a turning point from the substantial increases of the 1980s and 1990s the fall in inequality is significant and widespread but it does not seem to be based on strong fundamentals

performance pay and wage inequality an increasing fraction of jobs in the u s labor market explicitly pay workers for their performance using bonus pay commissions or piece rate contracts using data from the panel study of income dynamics we show that compensation in performance pay jobs is more closely tied to both observed and unobserved productive characteristics of workers than compensation in non performance pay jobs we also find that the return to these productive characteristics increased faster over time in performance pay than in non performance pay jobs we show that this finding is consistent with the view that underlying changes in returns to skill due for instance to technological change induce more firms to offer performance pay contracts and result in more wage inequality among workers who are paid for performance thus performance pay provides a channel through which underlying changes in returns to skill get translated into higher wage inequality we conclude that this channel accounts for 21 of the growth in the variance of male wages between the late 1970s and the early 1990s and for most of the increase in wage inequality above the eightieth percentile over the same period

estimates of the demand for energy using cross country consumption data using cross country consumption data we estimate a system of demand equations in a piecewise manner to investigate whether price and expenditure elasticities for energy differ between broad groups of countries the empirical results reject the assumption of constant parameters across regimes of poor and rich countries the derived elasticities suggest that the own price elasticity for energy is higher in poor than in rich countries we find no evidence for the commonly held view that expenditure elasticities for energy decline with income

is there curvature in the slutsky matrix d o the poor substitute among commodities more flexibly than the rich when relative prices change even when compensated for the income effects of the price changes is it necessary to add a third dimension to the slutsky substitution matrix to identify household income in short do the terms of the slutsky elasticity matrix curve smoothly from poor households to rich households in such a way that equation 1 is meaningful

corporate performance and managerial remuneration an empirical analysis abstract economic theories of efficient compensation predict a positive relationship between executive pay and corporate performance and yet efforts to document this relationship have been largely unsuccessful in this paper we argue that previous cross sectional studies have omitted important variables which seriously bias their results using data that focus on individual executives over time we find that executive compensation is strongly positively related to corporate performance as measured by shareholder return and growth in firm sales the results are robust to the stock market performance measure utilized

an analysis of the stock price reaction to sudden executive deaths implications for the managerial labor market abstract certain characteristics of managerial employment arrangements and of the managerial labor market make shareholder wealth dependent on an executive s continued employment these wealth effects are investigated by examining the common stock price reaction to unexpected deaths of senior corporate executives abnormal stock price changes are documented for a sample of fifty three events these abnormal stock price changes are associated with the executive s status as a corporate founder and with measures of the executive s talents and decision making responsibility and of the transaction costs associated with renegotiating or terminating the employment agreement

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

does the bonding effect matter in a more integrated capital market world abstract this paper examines the bonding effect of cross listing before and after the stock market liberalization reforms in china consistent with the bonding hypothesis we find that chinese firms with foreign listings attain higher valuations than firms without foreign listings we also find that they manage earnings less than comparable purely domestic listed firms and have more informative stock prices further investigation indicates that the divergence in earnings quality between cross listed and non cross listed firms shrinks dramatically after the chinese stock market liberalization reforms in 2001 and 2002 overall the results suggest that the bonding effect is mitigated in an increasingly integrated capital market world

energy consumption and economic activity in industrialized countries the dynamic aggregate time series relationship abstract most econometric studies suggest that the income elasticity of demand for energy is approximately unity for the developed market economies it is shown that over the period 1950 1978 the long run income elasticity is substantially higher than unity in terms of a ces energy demand function this result reflects the application of a generalized dynamic estimation methodology where serial correlation is regarded as a diagnostic guide to distributed lag fitting price elasticities are also estimated but these are in line with conventional estimates

the structure of ownership and the theory of the firm the separation of ownership from control produces a condition where the interests of owner and of ultimate manager may and often do diverge and where many of the checks which formerly operated to limit the use of power disappear in creating these new relationships the quasi public corporation may fairly be said to work a revolution it has divided ownership into nominal ownership and the power formerly joined to it thereby the corporation has changed the nature of profit seeking enterprise 1

inside the family firm the role of families in succession decisions and performance this paper uses a unique dataset from denmark to investigate the impact of family characteristics in corporate decision making and the consequences of these decisions on firm performance we focus on the decision to appoint either a family or an external chief executive officer ceo the paper uses variation in ceo succession decisions that result from the gender of a departing ceo s first born child this is a plausible instrumental variable iv as male firstchild firms are more likely to pass on control to a family ceo relative to female first child firms but the gender of a first child is unlikely to affect firms outcomes we find that family successions have a large negative causal impact on firm performance operating profitability on assets falls by at least four percentage points around ceo transitions our iv estimates are significantly larger than those obtained using ordinary least squares furthermore we show that family ceo underperformance is particularly large for firms in high growth industries and for relatively large firms overall the empirical results demonstrate that professional non family ceos provide extremely valuable services to the organizations they head

economic policy changes and wage differentials in latin america abstract this article presents estimates of the impact of changes in liberalization policies on wage differentials by schooling level using a new high quality data set for 18 latin american countries for 1977 98 the method controls for all fixed and time varying country characteristics some of which may affect the policies themselves the results indicate that liberalizing policy changes overall have had a short run disequalizing effect of expanding wage differentials although this effect tends to fade away over time this disequalizing effect is due to the strong impact of domestic financial market reform capital account liberalization and tax reform however privatization contributed to narrowing wage differentials and increasing trade openness had no significant effect on wage differentials technological progress rather than trade flows appears to be a channel through which policy changes are affecting inequality

cross sectoral variation in the volatility of plant level idiosyncratic shocks the volatility of plant level idiosyncratic shocks we estimate the volatility of plant level idiosyncratic shocks in u s manufacturing we measure the variation in revenue total factor productivity not explained by either industry or economy wide factors or by establishments characteristics we find that idiosyncratic shocks are much larger than aggregate shocks accounting for about 80 of the overall uncertainty faced by plants plants in the most volatile sector are subject to about six times as much idiosyncratic uncertainty as plants in the least volatile we provide evidence suggesting that idiosyncratic risk is higher in industries where the extent of creative destruction is likely to be greater

controlling the conflict of interest in management buyouts a controversial aspect of the management buyouts that were popular throughout the 1980s is the potential for a conflict of interest to arise when a manager bids to acquire the firm he manages this study examines 184 management buyouts and reports three findings first returns to prebuyout shareholders are greater when managers must bid against outside acquirers second bid revisions in the face of competition exceed revisions due to shareholder litigation and negotiations with boards third the incidence of competition is negatively related to the prebuyout share holdings of managers coauthors are ronald f singer anju seth and darla f lang copyright 1994 by mit press

varying heterogeneity among u s firms facts and implications abstract u s firms stock return volatility rose fivefold from 1971 through 2000 and then reverted to near 1971 levels by 2006 this was driven mainly by a rise and fall in the firm specific rather than systematic component of volatility firm level total factor productivity growth volatility exhibited a similar pattern we hypothesize that firm heterogeneity reflected in firm specific volatility rises as a new general purpose technology gpt propagates across the economy and then ebbs once the gpt is widespread measuring gpt adoption by information technology capital intensity we find robust cross industry empirical evidence supporting the hypothesis

the effect of financial development on convergence theory and evidence we introduce imperfect creditor protection in a multicountry schumpeterian growth model the theory predicts that any country with more than some critical level of financial development will converge to the growth rate of the world technology frontier and that all other countries will have a strictly lower long run growth rate we present evidence supporting these and other implications in the form of a cross country growth regression with a significant and sizable negative coefficient on initial per capita gdp relative to the united states interacted with financial intermediation in addition we find that other variables representing schooling geography health policy politics and institutions do not affect the significance of the interaction between financial intermediation and initial per capita gdp and do not show any independent effect on convergence in the regressions our findings are robust to removal of outliers and to alternative conditioning sets estimation procedures and measures of financial development

financial development and economic growth views and agenda this critique argues that the preponderance of theoretical reasoning and empirical evidence suggests a positive first order relationship between financial development and economic growth the body of work would push even most skeptics toward the belief that the development of financial markets and institutions is a critical and inextricable part of the growth process and away from the view that the financial system is an inconsequential sideshow responding passively to economic growth many gaps remain however and the paper highlights areas in acute need of additional research

who is afraid of political risk multinational firms and their choice of capital structure this paper investigates how multinational firms choose the capital structure of their foreign affiliates in response to political risk we focus on two choice variables the leverage and the ownership structure of the foreign affiliate and we distinguish different types of political risk such as expropriation unreliable intellectual property rights and confiscatory taxation in our theoretical analysis we find that as political risk increases the ownership share tends to decrease whereas leverage can both increase or decrease depending on the type of political risk using the microdatabase direct investment of the deutsche bundesbank we find supportive evidence for these different effects

entrenchment governance and the stock price reaction to sudden executive deaths abstract to study managerial entrenchment i use the stock price reaction to unexpected senior executive deaths if a highly effective manager dies unexpectedly the stock price reaction should be negative if however death removes an entrenched manager when the board would or could not the stock price reaction should be positive while individually age and tenure only weakly correlate with the stock price reaction to a sudden death the reaction is strongly positive 6 8 if 1 the executive s tenure exceeds 10 years and 2 abnormal stock returns over the last three years are negative

cross country evidence on the link between volatility and growth this paper presents empirical evidence against the standard dichotomy in macroeconomics that separates growth from the volatility of economic fluctuations in a sample of ninety two countries as well as a sample of oecd countries the authors find that countries with higher volatility have lower growth the addition of standard control variables strengthens the negative relationship the authors also find that government spending induced volatility is negatively associated with growth even after controlling for both time and country fixed effects copyright 1995 by american economic association

the information technology revolution and the stock market technological progress comes in waves the british industrial revolution 1760 1850 ushered in cort s puddling and rolling process for making iron crompton s mule for spinning cotton and the watt steam engine the second industrial revolution 1890 1930 witnessed the rise of electricity the internal combustion engine and the chemical industry the birth of information technology it may herald the start of a third industrial revolution a new technology or product is often developed by the single entrepreneur who initially finds it hard to get funds develop the product and find customers but if the product is good customers eventually line up and investors flock in other firms then move in to make the product and may drive the innovator out or acquire him whether he reaches the initial public offering ipo stage or is acquired by a listed firm though it takes time for the innovator to add value to the stock market indeed the innovation may at first reduce the market s value because some firms usually large or old will cling to old technologies that have lost their momentum figure 1 plots the market value of u s equity relative to gdp this paper argues that a the market declined in the late 1960 s because it felt that the old technologies either had lost their momentum or would give way to it and that b it innovators boosted the stock market s value only in the 1980 s if the stock market provides a forecast of future events then the recent dramatic upswing represents a rosy estimate about growth in future profits for the economy this translates into a forecast of higher output and productivity growth holding other things equal such as capital s share
