children education labor and land in the long run and short run the paper uses an overlapping generations model to examine the effects of an increase in a household s land ownership on child labor consistent with previous studies it found that small increases in land lead to increased child labor however as land continues to increase child labor declines further even when an increase in land ownership causes an immediate rise in child labor there are contexts where long run child labor that is aggregated over progenies declines jel o10 d13 e20

effects of economic shocks on children s employment and schooling in brazil abstract this paper uses longitudinal employment survey data to analyze the impact of household economic shocks on the schooling and employment transitions of young people in metropolitan brazil the paper uses data on over 100 000 children ages 10 16 from brazil s monthly employment survey pme from 1982 to 1999 taking advantage of the rotating panels in the pme we compare households in which the male household head becomes unemployed during a four month period with households in which the head is continuously employed probit regressions indicate that an unemployment shock significantly increases the probability that a child enters the labor force drops out of school and fails to advance in school the effects can be large implying increases of as much as 50 in the probability of entering employment for 16 year old girls in contrast shocks occurring after the school year do not have significant effects suggesting that these results are not due to unobserved characteristics of households that experience unemployment shocks the results suggest that some households are not able to absorb short run economic shocks with negative consequences for children

occupational choice and the process of development this paper models economic development as a process of institutional transformation by focusing on the interplay between agents occupational decisions and the distribution of wealth because of capital market imperfections poor agents choose working for a wage over self employment and wealthy agents become entrepreneurs who monitor workers only with sufficient inequality however will there be employment contracts otherwise there is either subsistence or self employment thus in static equilibrium the occupational structure depends on distribution since the latter is itself endogenous we demonstrate the robustness of this result by extending the model dynamically and studying examples in which initial wealth distributions have long run effects in one case the economy develops either widespread cottage industry self employment or factory production employment contracts depending on the initial distribution in the other example it develops into prosperity or stagnation

self fulfilling currency crises the role of interest rates abstract we develop a stylized currency crises model with heterogeneous information among investors andendogenous determination of interest rates in a noisy rational expectations equilibrium our modelcaptures three key features of interest rates the opportunity cost of attacking the currency respondsto the investors behavior the domestic interest rate may influence the central bank s preferences fora fixed exchange rate and the domestic interest rate serves as a public signal which aggregatesprivate information about fundamentals we explore the payoff and informational channels throughwhich interest rates determine devaluation outcomes and examine the implications for equilibriumselection by global games methods our main conclusion is that multiplicity is not an artifact ofcommon knowledge in particular we show that multiplicity emerges robustly either when adevaluation is triggered by the cost of high domestic interest rates as in obstfeld 1996 or when adevaluation is triggered by the central bank s loss of foreign reserves as in obstfeld 1986 providedthat the domestic asset supply is sufficiently elastic in the interest rate and shocks to the domesticbond supply are sufficiently small christian helliwigdepartment of economicsuniversity of california los angelesbox 951477los angeles ca 90095 1477arijit mukherjiuniversity of minnesotaaleh tsyvinskidepartment of economicsharvard universitylittauer centercambridge ma 02138 3001

the gender gap fertility and growth changes in fertility have long been recognized as important correlates of economic growth with the relationship between the level of fertility and the level of income per capita being one of the strongest observable correlations in cross country data this paper examines the linkages between fertility and growth theory the structure of the model is presented in sections on production couples decision making system dynamics and steady state equilibria the first component of the model is that increases in capital per worker raise womens relative wages since capital is more complementary to womens labor input than to mens the second component is that increasing womens relative wages reduces fertility by raising the cost of children more than household income finally lower fertility raises the level of capital per worker a positive feedback loop generates demographic transition a rapid decline in fertility accompanied by accelerated output growth

analyst forecasts and herding behavior the use of analyst forecasts as proxies for investors earnings expectations is commonplace in empirical research an implicit assumption behind their use is that they reflect analysts private information in an unbiased manner as demonstrated here this assumption is not necessarily valid there is shown to be a tendency for analysts to release forecasts closer to prior earnings expectations than is appropriate given their information further analysts exhibit herding behavior whereby they release forecasts similar to those previously announced by other analysts even when this is not justified by their information these results are shown to have interesting empirical implications article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

the economics of child labor if child labor as a mass phenomenon occurs not because of parental selfishness but because of the parents concern for the household s survival the popular argument for banning child labor loses much of its force however this assumption about parental decision making coupled with the assumption of substitutability in production between child and adult labor could result in multiple equilibria in the labor market with one equilibrium where children work and another where adult wage is high and children do not work the paper establishes this result and discusses its policy implications copyright 1998 by american economic association

are disclosures about bank derivatives and employee stock options value relevant abstract the papers by venkatachalam 1996 and aboody 1996 provide some interesting evidence on issues that are important to accounting regulators as well as accounting academics however for econometric as well as economic reasons there are limits to what we can learn from this type of research cross sectional levels studies careful attention to methodological issues in this type of research design can reduce but likely will not eliminate these interpretational difficulties

effect of derivative accounting rules on corporate risk management behavior abstract i examine the effect of the accounting standard for derivative instruments sfas no 133 on corporate risk management behavior i classify a derivative user as an effective hedger eh firm if its risk exposures decreased after the initiation of the derivatives program and as an ineffective hedger speculator is firm otherwise i find that volatility of cash flows and risk exposures related to interest rate foreign exchange rate and commodity price decrease significantly for is firms but not for eh firms suggesting that is firms engaged in more prudent risk management activities after the adoption of sfas no 133

income distribution and macroeconomics this paper analyzes the role of wealth distribution in macroeconomics through investment in human capital it is shown that in the presence of credit markets imperfections and indivisibilities in investment in human capital the initial distribution of wealth affects aggregate output and investment both in the short and in the long run as there are multiple steady states this paper therefore provides an additional explanation for the persistent differences in per capita output across countries furthermore the paper shows that cross country differences in macroeconomic adjustment to aggregate shocks can be attributed among other factors to differences in wealth and income distribution across countries

international labor standards and the political economy of child labor regulation child labor is a persistent phenomenon in many developing countries in recent years support has been growing among rich country governments and consumer groups for the use of trade policies such as product boycotts and the imposition of international labor standards to reduce child labor in poor countries in this paper we discuss research on the long run implications of such policies in particular we demonstrate that such measures may have the unintended side effect of lowering domestic support for banning child labor within developing countries and thus may contribute to the persistence of the child labor problem jel i21 j88 o11 o19 o24

child labour a review of recent theory and evidence with policy implications in recent years a growing number of authors have turned their attention to the question of why children work the purpose of this paper is to review some of the more recent theoretical and empirical research into the topic of child labour and to illustrate the fact that no one factor on its own can account for the phenomenon of child labour therefore policies aimed at eradicating child labour will need to address the broad range of underlying factors that contribute to the incidence of child labour such as poverty market imperfections and access to education

is child labor inefficient we build a model of child labor and study its implications for welfare we assume that there is a trade off between child labor and the accumulation of human capital even if parents are altruistic and child labor is socially inefficient it may arise in equilibrium because parents fail to fully internalize its negative effects this occurs when bequests are zero or when capital markets are imperfect we also study the effects of a simple ban on child labor and derive conditions under which it may be pareto improving in general equilibrium we show that the implications of child labor for fertility are ambiguous

financial analyst characteristics and herding behavior in forecasting this study classifies analysts earnings forecasts as herding or bold and finds that 1 boldness likelihood increases with the analyst s prior accuracy brokerage size and experience and declines with the number of industries the analyst follows consistent with theory linking boldness with career concerns and ability 2 bold forecasts are more accurate than herding forecasts and 3 herding forecast revisions are more strongly associated with analysts earnings forecast errors actual earnings forecast than are bold forecast revisions thus bold forecasts incorporate analysts private information more completely and provide more relevant information to investors than herding forecasts

gaap versus the street an empirical assessment of two alternative definitions of earnings managers security analysts investors and the press rely increasingly on modified definitions of gaap net income known by such names as operating and pro forma earnings we document this phenomenon and discuss competing explanations for the recent rise in the use of such modified earnings numbers and implications for the interpretation of related accounting research our results show that over the past 20 years there has been a dramatic increase in the frequency and magnitude of cases where gaap and street earnings differ further there is a very strong bias toward the reporting of a street earnings number that exceeds the gaap earnings number we also show that the market response to the street earnings number has displaced gaap earnings as a primary determinant of stock prices finally through an analysis of earnings releases we show that management has taken a proactive role in defining and emphasizing the street number when communicating to analysts and investors

do analysts understand the economic and reporting complexities of derivatives we investigate whether and how the complexity of derivatives influences analysts earnings forecast properties using a difference in differences design we find that relative to a matched control sample of non users analysts earnings forecasts for new derivatives users are less accurate and more dispersed after derivatives initiation these results do not appear to be driven by the economic complexity of derivatives but rather the financial reporting of such economic complexity overall despite their financial expertise analysts routinely misjudge the earnings implications of firms derivatives activity however we find evidence that a series of derivatives accounting standards has helped analysts improve their forecasts over time

drought of opportunities contemporaneous and long term impacts of rainfall shocks on human capital higher wages are generally thought to increase human capital production particularly in the developing world we introduce a simple model of human capital production in which investments and time allocation differ by age using data on test scores and schooling from rural india we show that higher wages increase human capital investment in early life in utero to age 2 but decrease human capital from age 5 to 16 children switch out of school into productive work when rainfall is higher the opportunity cost of schooling even for fairly young children is an important factor in determining overall human capital investment

dynamic forecasting behavior by analysts theory and evidence abstract we develop a multi period learning model to examine the relation between analysts forecasting behavior and their performance in a competitive market for banking services the surplus and the analyst s payoff which is determined through bargaining are convex in her reputation the convexity of her payoff structure and the presence of employment risk lead to a u shaped relation between the analyst s forecast boldness and prior performance and a positive relation between forecast boldness and experience we find support for these predictions in our empirical analysis significant underperformers outperformers face higher lower employment risk and are more likely to issue bolder forecasts

trading frenzies and their impact on real investment we study a model in which a capital provider learns from the price of a firm s security in deciding how much capital to provide for new investment this feedback effect from the financial market to the investment decision gives rise to trading frenzies in which speculators all wish to trade like others generating large pressure on prices coordination among speculators is sometimes desirable for price informativeness and investment efficiency but speculators incentives push in the opposite direction so that they coordinate exactly when it is undesirable we analyze the effect of various market parameters on the likelihood of trading frenzies to arise

the effect of cash flow forecasts on accrual quality and benchmark beating when analysts provide forecasts of both earnings and operating cash flow they also implicitly provide a forecast of total operating accruals we posit that this increases the transparency and the expected costs of accrual manipulations used to manage earnings as a consequence we predict and find that accrual quality improves and firms propensity to meet or beat earnings benchmarks declines following the provision of cash flow forecasts we also predict and find that firms turn to other benchmark beating mechanisms such as real activities manipulation and earnings guidance in response to the provision of cash flow forecasts

forecasting bankruptcy more accurately a simple hazard model i argue that hazard models are more appropriate than single period models for forecasting bankruptcy single period models are inconsistent while hazard models produce consistent estimates i describe a simple technique for estimating a discrete time hazard model i find that about half of the accounting ratios that have been used in previous models are not statistically significant moreover market size past stock returns and idiosyncratic returns variability are all strongly related to bankruptcy i propose a model that uses both accounting ratios and market driven variables to produce out of sample forecasts that are more accurate than those of alternative models copyright 2001 by university of chicago press

the macroeconomics of child labor regulation we develop a positive theory of the adoption of child labor laws workers who compete with children in the labor market support a child labor ban unless their own working children provide a large fraction of family income fertility decisions lock agents into specific political preferences and multiple steady states can arise the introduction of child labor laws can be triggered by skill biased technological change which induces parents to choose smaller families the theory can account for the observation that in britain regulations were first introduced after a period of rising wage inequality and coincided with rapid fertility decline

the going public decision and the development of financial markets this paper explores the linkages between stock price efficiency the choice between private and public financing and the development of capital markets in emerging economies generally the advantage of public financing is high if costly information is diverse and cheap to acquire and if investors receive valuable information without cost the value of public firms generally depends on public market size which implies that there can be a positive externality associated with going public so that an inferior equilibrium can exist where too few firms go public the model is consistent with empirical observations on financial market development

the impact of derivatives on firm risk an empirical examination of new derivative users abstract the appropriateness of financial reporting rules for derivative securities depends on corporations reasons for using the instruments empirically little is documented about how the instruments affect firms risk exposures this study examines derivatives roles in firms initiating derivatives use the results are consistent with firms using derivatives to hedge and not to increase entity risk firm risk measured several ways declines following derivatives use realized risk reductions and decisions to initiate derivatives programs vary across firms with the expected benefits from hedging the findings emphasize the importance of hedge accounting rules that incorporate the impact of derivatives and hedged items simultaneously

the economics of child labor comment in a recent paper kaushik basu and pham hoang van bv 1998 develop an important and very interesting model in which a fairly productive economy exhibits multiple equilibria with children working in at least one they identify two assumptions as essential to this result the first which they call the luxury axiom is that a family sends its children to the labor market only if its income from sources other than child labor is very low the second is embodied in their substitution axiom which states that from the point of view of firms child labor is substitutable for adult labor in this comment we show that in addition to these two assumptions about the micro level behavior of households and firms there is also an essential macro level assumption that may be termed the distribution axiom income or wealth from non labor sources must be sufficiently concentrated in the hands of a few agents we establish that if non labor income is distributed with sufficient equality a market equilibrium with child labor cannot exist in the bv model beyond their contribution as an extension of bv s theory our results formalize a proposition implicit in recent policy discussions of child labor christiaan grootaert and ravi kanbur 1995 note that as household level poverty is well known to be the major cause of child labor g eneral economic development equitably distributed is the best and most sustainable way of reducing child labor p 198 emphasis added policy documents from the international labor organization ilo have long conveyed this view and now the world bank appears to as well peter fallon and zafiris tzannatos 1998 there is a growing recognition that while economic development and development policies are necessary to eliminating child labor they are not always sufficient on their own distributional considerations matter indeed in the case in which bv s model yields multiple equilibria th this abstract was borrowed from another version of this item

insider trading in a rational expectations economy it is often argued that efficiency considerations require society to freely permit insider trading in this article an opposing efficiency argument is formalized the model incorporates an investment stage followed by a trading stage if outsiders expect insiders to take advantage of them in trading outsiders will reduce their investment the insiders loss from this diminished investor confidence may more than offset their trading gains consequently a prohibition on insider trading may effect a pareto improvement insiders are made better off if they can precommit not to trade on their privileged information govemment regulation accomplishes exactly this jel 022 026 313 the traditional rationale articulated for insider trading regulation and other securities law is that such rules promote confidence in markets indeed president franklin d roosevelt justified the first major u s securities legislation by saying it should give impetus to honest dealing in securities and thereby bring back public confidence similar language is still invoked half a century later in connection with enforcement efforts against insider trading and in proposals for tightened stock

the source of information in prices and investment price sensitivity abstract this paper shows that real decisions depend not only on the total amount of information in prices but the source of this information a manager learns from prices when they contain information not possessed by him we use the staggered enforcement of insider trading laws across 27 countries as a shock to the source of information that leaves total information unchanged enforcement reduces increases managers outsiders contribution to the stock price consistent with the predictions of our theoretical model enforcement increases investment q sensitivity even when controlling for total price informativeness the effect is larger in industries where learning is likely to be stronger and in emerging countries where outsider information acquisition rises most post enforcement enforcement does not increase the sensitivity of investment to cash flow a non price measure of investment opportunities these findings suggest that extant measures of price efficiency should be rethought when evaluating real efficiency more broadly our paper provides causal evidence that managers learn from prices by using a shock to price informativeness

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

security analysts career concerns and herding of earnings forecasts several theories of reputation and herding see e g scharfstein and stein 1990 suggest that herding among agents should vary with career concerns our goal in this paper is to document whether such a link exists in the labor market for security analysts specifically we look at the relationship between an analyst s job tenure a proxy for career concerns and various measures of stock earnings forecast performance we establish the following key results 1 older analysts are more likely to produce earnings forecasts of firms before younger ones 2 their forecasts also deviate more from the consensus forecast than their younger counterparts we argue that these results are consistent with some reputational models of herding we also establish a number of auxiliary findings regarding the relationship between forecast accuracy and frequency of forecast revisions with job tenure

on the determinants of corporate hedging finance theory indicates that hedging increases firm value by reducing expected taxes expected costs of financial distress or other agency costs this paper provides evidence on these hypotheses using survey data on firm s use of forwards futures swaps and options combined with computstat data on firm characteristics of 169 firms in the sample 104 firms use hedging instruments in 1986 the data suggest that firms which hedge face more convex tax functions have less coverage of fixed claims are larger have more growth options in their investment opportunity set and employ fewer hedging substitutes
