development fertility and childbearing age a unified growth theory during the last two centuries fertility has exhibited in industrialized economies two distinct trends the cohort total fertility rate follows a decreasing pattern while the cohort average age at motherhood exhibits a u shaped pattern this paper proposes a unified growth theory aimed at rationalizing those two demographic stylized facts we develop a three period olg model with two periods of fertility and show how a traditional economy where individuals do not invest in higher education and where income rises push towards advancing births can progressively converge towards a modern economy where individuals invest in higher education and where income rises encourage postponing births our findings are illustrated numerically by replicating the dynamics of the quantum and the tempo of births for swedish cohorts born between 1876 and 1966

does financial education impact financial literacy and financial behavior and if so when in a meta analysis of 126 impact evaluation studies we find that financial education significantly impacts financial behavior and to an even larger extent financial literacy these results also hold for the subsample of randomized experiments rcts however intervention impacts are highly heterogeneous financial education is less effective for low income clients as well as in low and lower middle income economies specific behaviors such as the handling of debt are more difficult to influence and mandatory financial education tentatively appears to be less effective thus intervention success depends crucially on increasing education intensity and offering financial education at a teachable moment

are price limits really bad for equity markets despite widely documented criticisms price limit rules are present in many equity markets around the world using a game theoretic model we argue that if the cost of monitoring a market is high price limit rules are beneficial empirical tests based on a cross section of 43 equity markets across five continents support our theoretical prediction we find that the probability of the existence of price limit rules is greater in markets that incur higher monitoring costs due to poorer business disclosure more corruption and less efficiency in legal regulatory and technological environments

alfred marshall lecture social capital as good culture to explain the extremely long term persistence more than 500 years of positive historical experiences of cooperation putnam 1993 we model the intergenerational transmission of priors about the trustworthiness of others we show that this transmission tends to be biased toward excessively conservative priors as a result societies can be trapped in a low trust equilibrium in this context a temporary shock to the return to trusting can have a permanent effect on the level of trust we validate the model by testing its predictions on the world values survey data and the german socio economic panel we also present some anecdotal evidence that these priors are reflected in novels that originate in different parts of the country jel 04 016 043 p16

prices or knowledge what drives demand for financial services in emerging markets this brief summarizes the results of a gender impact evaluation study entitled prices or knowledge what drives demand for financial services in emerging markets conducted in 2008 in indonesia the study observed that financial development is critical for growth but its micro determinants are not well understood financial literacy training has no impact on the probability of opening a bank account although it does have an impact among those with low levels of education and financial literacy a change from 3 to 14 led to a 7 6 percent increase in the probability of owning a bank account the results hold two years after a study funding for the study derived from world bank hbs division of research and faculty development

innovation and inequality in a small world we present a multicountry theory of economic growth and r d driven technological progress in which countries are connected by a network of knowledge exchange technological progress in any country depends on the state of technology in the countries it exchanges knowledge with the diffusion of knowledge throughout the world explains a period of increasing world inequality followed by decreasing relative inequality knowledge diffusion through a small world network produces an extraordinary diversity of country growth performances including the overtaking of individual countries and the replacement of the technologically leading country in the course of world development

microstructure bluffing with nested information chakraborty and yilmaz 2004a b con sider strategic models of repeated trading by an informed insider with long lived private infor mation they show that if market makers face uncertainty about the existence of informed trades in the order flow then with sufficiently many periods of trading the insider will bluff in every equilibrium in the precise sense ruled out in albert s kyle 1985 1323 i e by first destabilizing prices with unprofitable trades made at the nth auction then recouping the losses and much more with profitable trades at future auctions by bluffing the insider adds noise to the market s inference problem and makes prices less sensitive to his trades in this note we demonstrate how the scope for profitable bluffing is enhanced by the pres ence of other rational informed traders in the

delegated trading and the speed of adjustment in security prices abstract institutional trading arrangements often involve the portfolio manager delegating the task of trade execution to a separate division within the firm we model the agency conflict that arises in this setting and show that optimal performance benchmarks often create an incentive to execute orders contrary to concurrent information flow we hypothesize that aggregate contrarian trading resulting from widespread application of such benchmarks leads to delays in the assimilation of information in security prices using institutional trading data we document the hypothesized contrarian trading pattern and relate the pattern to price adjustment delays in the response of individual stocks to index futures returns the evidence supports the assertion that delegated institutional trading contributes to these delays

high frequency trading and extreme price movements abstract are endogenous liquidity providers elps reliable in times of market stress we examine the activity of a common elp type high frequency traders hfts around extreme price movements epms we find that on average hfts provide liquidity during epms by absorbing imbalances created by non high frequency traders nhfts yet hft liquidity provision is limited to epms in single stocks when several stocks experience simultaneous epms hft liquidity demand dominates their supply there is little evidence of hfts causing epms

information disclosure and price manipulation during the pre closing session evidence from an order driven market on 20 february 2012 the taiwan stock exchange corporation launched an order matching simulation mechanism for five minutes during the start of the pre closing session in order to increase information disclosure during this period 13 25 13 30 pre closing information disclosure significantly reduces both trading costs and closing price volatility as well as price manipulation the decrease in price manipulation found in this work is due to pre closing information disclosure not the behaviour of investors shifting to an earlier time further if a stock price rises or falls by more than 3 5 in the simulation in the last minute during the closing session trading of the stock will be suspended for two minutes from 13 31 to reduce volatility however this trading mechanism suspended closing does not seem to have achieved the intended goals of the authorities as it has not been able to significantly reduce closing price volatility and price manipulation

the impact of fraudulent false information on equity values there are two types of stock price manipulation examined in the theoretical literature 1 insider trading which involves private information that is true and 2 the public spreading of fraudulent false information while there is a large empirical literature on insider trading this is the first empirical article to examine the impact of false fraudulent public information on stock prices and trading volume we find that such false information even after being denied by a credible source such as the sec generates both abnormal returns and abnormal trading volume we also find that the effects of the false information on security returns and volume can be persistent for at least 2 weeks in addition we show that perpetrators of false news attacks can make potentially large profits from such market manipulations

the antidirector rights index revisited the antidirector rights index has been used as a measure of shareholder protection in over a hundred articles since it was introduced by la porta et al law and finance 1998 journal of political economy 106 1113 55 a thorough reexamination of the legal data however leads to corrections for thirty three of the forty six countries analyzed the correlation between corrected and original values is only 0 53 consequently many empirical results established using the original index may not be replicable with corrected values in particular the corrected index fails to support three widely influential claims that shareholder protection is higher in common than in civil law countries that shareholder protection predicts stock market size or ownership dispersion and that weak corporate governance explains the extent of exchange rate depreciation during the asian financial crisis of 1997 1998 the author 2009 published by oxford university press on behalf of the society for financial studies all rights reserved for permissions please e mail journals permissions oxfordjournals org oxford university press

learning by doing and learning from others human capital and technical change in agriculture household level panel data from a nationally representative sample of rural indian households describing the adoption and profitability of high yielding seed varieties hyvs associated with the green revolution are used to test the implications of a model incorporating learning by doing and learning spillovers the estimates indicate that i imperfect knowledge about the management of the new seeds was a significant barrier to adoption ii this barrier diminished as farmer experience with the new technologies increased iii own experience and neighbors experience with hyvs significantly increased hyv profitability and iv farmers do not fully incorporate the village returns to learning in making adoption decisions

planning and financial literacy how do women fare many older us households have done little or no planning for retirement and there is a substantial population that seems to undersave for retirement of particular concern is the relative position of older women who are more vulnerable to old age poverty due to their longer longevity this paper uses data from a special module we devised on planning and financial literacy in the 2004 health and retirement study it shows that women display much lower levels of financial literacy than the older population as a whole in addition women who are less financially literate are also less likely to plan for retirement and be successful planners these findings have important implications for policy and for programs aimed at fostering financial security at older ages

does insider trading raise market volatility this paper studies the role of insider trading in explaining cross country differences in stock market volatility it introduces a new measure of insider trading the central finding is that countries with more prevalent insider trading have more volatile stock markets even after one controls for liquidity maturity of the market and the volatility of the underlying fundamentals volatility of real output and of monetary and fiscal policies moreover the effect of insider trading is quantitatively significant when compared with the effect of economic fundamentals

manipulating market sentiment we analyze a simple model of an asset market in which a large rational trader interacts with noise speculators who seek short run speculative gains and become active following a prolonged episode of mispricing relative to the asset s fundamental value the model gives rise to price patterns such as bubble dynamics positive short run correlation and vanishing long run correlation of price deviations from the fundamental value we argue that this example model sheds light on the question as to whether rational speculators abet or curb price fluctuations

equilibrium pricing and trading volume under preference uncertainty information collection processing and dissemination financial institutions is challenging this can delay the observation by traders of the exact capital charges and constraints of their institution during this delay traders face preference uncertainty in this context we study optimal trading strategies and equilibrium prices in a continuous centralized market we focus on liquidity shocks during which preference uncertainty is likely to matter most preference uncertainty generates allocative ineficiency but need not reduce prices traders progressively learning about the preferences of their institution conduct round trip trades which generate excess volume relative to the frictionless market in a cross section of liquidity shocks the initial price drop is positively correlated with total trading volume across traders the number of round trips is negatively correlated with trading profits and average inventory

kinship and financial networks formal financial access and risk reduction kinship networks are beneficial for smoothing consumption and investment but the channels are not well understood we study the financing devices used for consumption and investment by thai households households that are connected to banks achieve significantly better consumption smoothing than unconnected households indirect connections via inter household borrowing are as effective as direct borrowing investment appears to be facilitated by kinship households with kin in the village display reduced sensitivity of investment to income while connections to banks do not significantly reduce sensitivity kin may act as implicit collateral permitting borrowing that would violate repayment constraints in its absence

the effects of financial education in the workplace evidence from a survey of households abstract we use a novel household survey to investigate the effects of employer based financial education on personal saving we explore cross sectional relations between the availability of employer based financial education and various measures of asset accumulation and we interpret these patterns in light of various potentially confounding factors our findings favor the hypothesis that employer based financial education stimulates saving both in general and for retirement

market conditions fragility and the economics of market making abstract using audit trail data from the toronto stock exchange we find that market makers scale back in unison when market conditions are unfavorable which contributes to covariation in liquidity supply both within and across stocks market conditions lower aggregate participation via their impact on trading profits and risk contrary to regulatory view higher stock volatility is associated with more participation and higher profits even after controlling for other market conditions including stock volume fragility concerns extend to larger stocks and to active participants the designated market maker mitigates periodic illiquidity created by synchronous withdrawal of market makers in large and small stocks

the economic importance of financial literacy theory and evidence this paper undertakes an assessment of a rapidly growing body of economic research on financial literacy we start with an overview of theoretical research which casts financial knowledge as a form of investment in human capital endogenizing financial knowledge has important implications for welfare as well as policies intended to enhance levels of financial knowledge in the larger population next we draw on recent surveys to establish how much or how little people know and identify the least financially savvy population subgroups this is followed by an examination of the impact of financial literacy on economic decision making in the united states and elsewhere while the literature is still young conclusions may be drawn about the effects and consequences of financial illiteracy and what works to remedy these gaps a final section offers thoughts on what remains to be learned if researchers are to better inform theoretical and empirical models as well as public policy jel a20 d14 g11 i20 j26

trust social capital and economic development many argue that elements of a society s norms culture or social capital are central to understanding its development however these notions have been difficult to capture in economic models here we explore ap ossible role for trustworthiness as corresponding to social capital individuals are trustworthy when they perform in accordance with promises even if this does not maximize their payoffs the usual focus on incentive structures in motivating behaviour plays no role here instead we emphasize more deep seated modes of behaviour and consider trustworthy agents being socialized to act as they do to model this socialization we borrow from a process of preference evolution pioneered by bisin and verdier 2001 the model developed endogenously accounts for social capital and explores its role in the process of economic development it captures in a simple formal way the interaction between social capital and the economy s productive processes the results obtained caution against rapid reform and provide an explanation for why late developing countries may not easily be able to transplant the modes of production that have proved useful in the west

social capital and growth we define and characterize social capital in a simple growth model we capture social capital in a model where individuals in a community maximize their lifetime gains to trade each trade between two members of a community has the structure of the prisoners dilemma trades are repeated indefinitely but not necessarily each period social capital is defined as the social structure which facilitates cooperative trade as an equilibrium the trading model is incorporated into a growth model to explore the connections between growth labor mobility and social capital the key assumption is that technological innovation which drives growth involves a reallocation of labor that affects social capital modifying the responsiveness of labor to a technological shock has implications for both labor efficiency and social capital

information aggregation and manipulation in an experimental market prediction markets are increasingly being considered as methods for gathering summarizing and aggregating diffuse information by governments and businesses alike critics worry that these markets are susceptible to price manipulation by agents who wish to distort decision making we study the effect of manipulators on an experimental market we find that manipulators are unable to distort price accuracy subjects without manipulation incentives compensate for the bias in offers from manipulators by setting a different threshold at which they are willing to accept trades

financial literacy and financial behaviour experimental evidence from rural rwanda we organise a field experiment with smallholder farmers in rwanda to measure the impact of financial literacy training on financial knowledge and behaviour the training increased financial literacy of participants changed their savings and borrowing behaviour and had a positive effect on the new business start up however it failed to have a significant short term impact on income using a two stage regression framework we identify enhanced financial literacy as one of the important factors explaining behavioural changes we also test whether financial knowledge spillovers from trained farmers to their peers in local village banks but find no evidence for that

trust in large organizations several authors suggest that trust is an important determinant of cooperation between strangers in a society and therefore of performance of social institutions we argue that trust should be particularly important for the performance of large organizations in a cross section of countries evidence on government performance participation in civic and professional societies importance of large firms and the performance of social institutions more generally supports this hypothesis moreover trust is lower in countries with dominant hierarchical religions which may have deterred networks of cooperation trust hold up remarkably well on a cross section of countries this abstract was borrowed from another version of this item

strategic trading behavior and price distortion in a manipulated market anatomy of a squeeze abstract this paper investigates an attempted delivery squeeze in a bond futures contract traded in london using cash and futures trades of dealers and customers we analyze their strategic trading behavior price distortion and learning in a market manipulation setting we argue that marked differences in settlement failure penalties in the cash and futures markets create conditions that favor squeezes we recommend that regulators require special flagging of forward term repurchase agreements on the key deliverables that span futures contract maturity dates and that exchanges mark to market their contract specifications more frequently or consider a cash settled contract on a basket of bonds

beyond baseline and follow up the case for more t in experiments the vast majority of randomized experiments in economics rely on a single baseline and single follow up survey if multiple follow ups are conducted the reason is typically to examine the trajectory of impact effects so that in effect only one follow up round is being used to estimate each treatment effect of interest while such a design is suitable for study of highly autocorrelated and relatively precisely measured outcomes in the health and education domains this paper makes the case that it is unlikely to be optimal for measuring noisy and relatively less autocorrelated outcomes such as business profits household incomes and expenditures and episodic health outcomes taking multiple measurements of such outcomes at relatively short intervals allows the researcher to average out noise increasing power when the outcomes have low autocorrelation it can make sense to do no baseline at all moreover the author shows how for such outcomes more power can be achieved with multiple follow ups than allocating the same total sample size over a single follow up and baseline the analysis highlights the large gains in power from ancova rather than difference in differences when autocorrelations are low and a baseline is taken the paper discusses the issues involved in multiple measurements and makes recommendations for the design of experiments and related non experimental impact evaluations

smart money the effect of education on financial outcomes household financial decisions are important for household welfare economic growth and financial stability yet our understanding of the determinants of financial decision making is limited exploiting exogenous variation in state compulsory schooling laws in both standard and two sample instrumental variable strategies we show that education increases financial market participation measured by investment income and equities ownership while dramatically reducing the probability that an individual declares bankruptcy experiences a foreclosure or is delinquent on a loan further results and a simple calibration suggest that the result is driven by changes in savings or investment behavior rather than simply increased labor earnings

baby boomer retirement security the roles of planning financial literacy and housing wealth abstract we compare wealth holdings across two cohorts of the health and retirement study the early baby boomers in 2004 and individuals in the same age group in 1992 levels and patterns of total net worth have changed relatively little over time though boomers rely more on housing equity than their predecessors most important planners in both cohorts arrive close to retirement with much higher wealth levels and display higher financial literacy than non planners instrumental variables estimates show that planning behavior can explain the differences in savings and why some people arrive close to retirement with very little or no wealth

trust and inter firm relations in developing and transition economies the role of trust in facilitating economic growth has been highlighted in previous contributions to this journal in order to take this debate forward this article argues 1 that more attention needs to be given to the relationship between sanctions and trust and 2 that it is worth distinguishing between the minimal trust for making markets effective and the extended trust required for deeper kinds of inter firm co operation to work the article goes on to ask why minimal trust is lacking and so hard to construct in the republics of the former soviet union it then examines how extended trust grows or can be made to grow in industrial supply chains and clusters in developing countries

trading frequency and volatility clustering abstract volatility clustering with autocorrelations of the hyperbolic decay rate is unquestionably one of the most important stylized facts of financial time series this paper presents a market microstructure model that is able to generate volatility clustering with hyperbolically decaying autocorrelations via traders with multiple trading frequencies using bayesian information updates in an incomplete market the model illustrates that signal extraction which is induced by multiple trading frequencies can increase the persistence of the volatility of returns furthermore we show that the volatility of the underlying time series of returns varies greatly with the number of traders in the market

anticipatory traders and trading speed we examine whether speed is an important characteristic of traders who anticipate local price trends these anticipatory participants correctly trade prior to the overall market and systematically act before other participants they use manual and algorithmic order entry methods but most are not fast enough to be high frequency traders hfts those anticipating price trends have impacts as if they are informed traders while the case for anticipatory participants affecting the volume of other traders is rejected a follow up sample shows significant attrition in accounts and difficulty maintaining the anticipatory strategies to identify anticipatory traders we devise novel methods to isolate local price trends using order book data from the west texas intermediate wti crude oil futures market

returns to capital in microenterprises evidence from a field experiment small and informal firms account for a large share of employment in developing countries the rapid expansion of microfinance services is based on the belief that these firms have productive investment opportunities and can enjoy high returns to capital if given the opportunity however measuring the return to capital is complicated by unobserved factors such as entrepreneurial ability and demand shocks which are likely to be correlated with capital stock the authors use a randomized experiment to overcome this problem and to measure the return to capital for the average microenterprise in their sample regardless of whether they apply for credit they accomplish this by providing cash and equipment grants to small firms in sri lanka and measuring the increase in profits arising from this exogenous positive shock to capital stock after controlling for possible spillover effects the authors find the average real return to capital to be 5 7 percent a month substantially higher than the market interest rate they then examine the heterogeneity of treatment effects to explore whether missing credit markets or missing insurance markets are the most likely cause of the high returns returns are found to vary with entrepreneurial ability and with measures of other sources of cash within the household but not to vary with risk aversion or uncertainty

the impact of financial literacy training for migrants remittances are a major source of external financing for many developing countries but the cost of sending them remains high in many migration corridors despite efforts to lower these costs by offering new products and developing cost comparison information sources many new and promising inexpensive remittance methods have relatively low adoption rates the lack of financial literacy among migrants has been identified as one potentially important barrier to competition and new product adoption this paper presents the results of a randomized experiment designed to measure the impact of providing financial literacy training to migrants training appears to increase financial knowledge and information seeking behavior and reduces the risk of switching to costlier remittance products but it does not result in significant changes in the frequency of remitting or in the remitted amount

the role of information and social interactions in retirement plan decisions evidence from a randomized experiment this paper analyzes a randomized experiment to shed light on the role of information and social interactions in employees decisions to enroll in a tax deferred account tda retirement plan within a large university the experiment encouraged a random sample of employees in a subset of departments to attend a benee ts information fair organized by the university by promising a monetary reward for attendance the experiment multiplied by more than e ve the attendance rate of these treated individuals relative to controls and tripled that of untreated individuals within departments where some individuals were treated tda enrollment e ve and eleven months after the fair was signie cantly higher in departments where some individuals were treated than in departments where nobody was treated however the effect on tda enrollment is almost as large for individuals in treated departments who did not receive the encouragement as for those who did we provide three interpretations differential treatment effects social network effects and motivational reward effects to account for these results

trust and social collateral this paper builds a theory of trust based on informal contract enforcement in social networks in our model network connections between individuals can be used as social collateral to secure informal borrowing we define network based trust as the largest amount one agent can borrow from another agent and derive a reduced form expression for this quantity which we then use in three applications 1 we predict that dense networks generate bonding social capital that allows transacting valuable assets whereas loose networks create bridging social capital that improves access to cheap favors such as information 2 for job recommendation networks we show that strong ties between employers and trusted recommenders reduce asymmetric information about the quality of job candidates 3 using data from peru we show empirically that network based trust predicts informal borrowing and we structurally estimate and test our model

nobody s business but my own self employment and small enterprise in economic development abstract in most poor countries small firms and self employment are the dominant forms of business enterprise even in the manufacturing sector for rich countries in contrast self employed people account for very small shares of manufacturing employment and output this paper builds on lucas 1978 on the size distribution of business firms bell journal of economics 9 2 508 523 to ask whether structural changes of this kind are driven by productivity differences a model calibrated to japanese time series data is shown to mimic key features of cross country and time series data the results support the idea that changes in aggregate productivity account for much of the cross country variation in establishment size and self employment rates

stock price manipulation it is generally agreed that speculators can make profits from insider trading or from the release of false information both forms of stock price manipulation have now been made illegal in this article the authors ask whether it is possible to make profits from a different kind of manipulation in which an uninformed speculator simply buys and sells shares they show that in a rational expectations framework where all agents maximize expected utility it is possible for an uninformed manipulator to make a profit provided investors attach a positive probability to the manipulator being an informed trader article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

high frequency trading and end of day price dislocation abstract we show that the presence of high frequency trading hft has significantly mitigated the frequency and severity of end of day price dislocation the effect of hft is more pronounced on days when end of day price dislocation is more likely to be the result of market manipulation moreover the effect of hft is more pronounced than the role of trading rules surveillance enforcement and legal conditions in curtailing the frequency and severity of end of day price dislocation we show our findings are robust to different proxies of the start of hft by trade size cancellation of orders and co location

why regulate insider trading evidence from the first great merger wave 1897 1903 we use event time methodology to study legal insider trading associated with mergers circa 1900 for mergers with prospective disclosures similar to today s we find substantial value gains at announcement implying participation by outside shareholders despite the absence of insider constraints furthermore preannouncement stock price runups relative to total value gain are no more than those observed for modern mergers insider regulation apparently has produced little benefit for outsiders with the inside information pricing function and related gains shifting to external information specialists other results suggest market penalties for nondisclosure i e insider trading is less successful in a restricted information environment

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

should continued family firms face lower taxes than other estates abstract taxes on estates and inheritances may induce heirs to discontinue family firms because firm dissolution incurs transaction costs a preferential tax treatment of transferred family businesses seems to be desirable from a macroeconomic viewpoint the support of dynastic succession however entails also a cost on the economy if firm continuation by less able heirs prevents entry into entrepreneurship here we investigate analytically and quantitatively the trade off between transaction costs saved and creative destruction prevented we find that a unique general equilibrium exists at which depending on the institutional setup low ability heirs either abandon type 1 or continue type 2 a family business a calibration of the model with german data suggests that preferential tax treatment of family firms has severe negative consequences on macroeconomic performance if it causes a threshold crossing from type 1 to type 2 equilibrium it also reveals that the descendants of less able entrepreneurs who were caused by continuation friendly tax policy to keep a family business always lose relative to their status in an economy without such a policy

saving in developing countries theory and review in the literature on economic development much of the interest in saving has been focused on the relation between saving and growth but saving is not only about accumulation it is about smoothing consumption in the face of volatile and unpredictable income and helping to ensure the living standards of poor people whose lives are difficult and uncertain this paper develops a model of households which cannot borrow but which accumulate assets as a buffer stock to protect consumption when incomes are low such households dissave as often as they save do not accumulate assets over the long term and have on average very small asset holdings but their consumption is markedly smoother than their income much of the evidence is as consistent with this view of saving as it is incosistent with standard views of smoothing over the life cycle and with explanations of the link between saving and growth in terms of life cycle saving behavior consumption smoothing is also a useful way of thinking about government policy where volatility in the world prices of taxed commodities can generate sharp fluctuations in government revenues as well as reallocations of revenue between the private and public sectors many important policy issues in developing countries hinge on issues of consumption and smoothing and research on these issues is currently likely to be more productive than work on the relation between saving and growth

non fundamental speculation we study an intertemporal asset market where insiders coexist with non fundamental speculators non fundamental speculators possess no private information on fundamental values of assets but have superior knowledge about some aspect of the market environment we show that the entry of these rational speculators can lead to reductions in market liquidity and in the information content of prices even in an efficient market also equilibrium trades display patterns of empirical interest for example speculators appear to chase trends and lose money after market overreactions while insiders trade as contrarians and profit after such overreactions

corporate prediction markets evidence from google ford and firm x despite the popularity of prediction markets among economists businesses and policymakers have been slow to adopt them in decision making most studies of prediction markets outside the lab are from public markets with large trading populations corporate prediction markets face additional issues such as thinness weak incentives limited entry and the potential for traders with biases or ulterior motives raising questions about how well these markets will perform we examine data from prediction markets run by google ford motor company and an anonymous basic materials conglomerate firm x despite theoretically adverse conditions we find these markets are relatively efficient and improve upon the forecasts of experts at all three firms by as much as a 25 reduction in mean squared error the most notable inefficiency is an optimism bias in the markets at google the inefficiencies that do exist generally become smaller over time more experienced traders and those with higher past performance trade against the identified inefficiencies suggesting that the markets efficiency improves because traders gain experience and less skilled traders exit the market

human and financial capital for microenterprise development evidence from a field and lab experiment microenterprises constitute an important source of employment and developing such enterprises is a key policy concern in most countries but what is the most efficient tool for microenterprise development we study this question in a developing country context tanzania where microenterprises are the source of employment for more than half of the labor force and we report from a field experiment that jointly investigated the importance of a human capital intervention business training and a financial capital intervention business grant using data from three survey rounds a lab experiment and administrative records of the microfinance institution we present evidence on business performance management practices happiness business knowledge and noncognitive abilities our study demonstrates strong effects of the combination of the two interventions on male entrepreneurs while the effects on female entrepreneurs are much more muted the results suggest that long term finance is an important constraint for microfinance entrepreneurs but that business training is essential to transform financial capital into productive investments our study also points to the need for more comprehensive measures to promote the businesses of female entrepreneurs data as supplemental material are available at http dx doi org 10 1287 mnsc 2014 1933 this paper was accepted by john list behavioral economics

social capital inclusive networks and economic performance abstract empirical studies show that the relationship between social capital and economic performance is ambiguous the paper points to the potential trade off between the sustainability of self enforcement and the magnitude of gains from trade in social networks as an explanation based on an infinitely repeated multi player prisoners dilemma it is shown how self enforcement of cooperation within a network is influenced by its inclusiveness its communication capacity and the complexity of the exchange setting the paper shows that inclusive social capital can combine both low enforcement costs and high gains from trade even in a complex exchange setting

experimental evidence on returns to capital and access to finance in mexico a strong theoretical argument for focusing on access to finance is that financial market imperfections can result in large inefficiencies as firms with productive investment opportunities underinvest lack of access to finance is a frequent complaint of microenterprises which account for a large share of employment in developing countries however assessing the extent to which a lack of capital affects their business profits is complicated by the fact that business investment is likely to be correlated with a host of unmeasured characteristics of the owner and firm such as entrepreneurial ability and demand shocks in a randomized experiment that gave cash and in kind grants to small retail firms providing an exogenous shock to capital the shock generated large increases in profits with the effects concentrated among firms that were more financially constrained the estimated return to capital was at least 20 33 percent a month three to five times higher than market interest rates

using privileged information to manipulate markets insiders gurus and credibility access to private information is shown to generate both the incentives and the ability to manipulate asset markets through strategically distorted announcements the fact that privileged information is noisy interferes with the public s attempts to learn whether such announcements are honest it allows opportunistic individuals to manipulate prices repeatedly without ever being fully found out this leads us to extend sobel s 1985 model of strategic communication to the case of noisy private signals our results show that when truthfulness is not easily verifiable restrictions on trading by insiders may be needed to preserve the integrity of information embodied in prices

the stock pools and the securities exchange act abstract the stated justification for the securities exchange act of 1934 exchange act was to eliminate manipulation the primary evidence of manipulation was the existence of stock pools through which groups of traders jointly traded in a particular stock the conclusion of congress that the pools were manipulative is inconsistent with the evidence produced by the senate s own investigation the returns on a sample of pool stocks are also inconsistent with manipulation these findings suggest that congressional and presidential desires to increase political control over the new york stock exchange was a more important motivation for the exchange act

the effects of financial education in the workplace evidence from a survey of employers we examine the effects of education on financial decision making skills by identifying an interesting source of variation in pertinent training during the 1990s an increasing number of individuals were exposed to programs of financial education provided by their employers if as some have argued low saving frequently results from a failure to appreciate economic vulnerabilities then education of this form could prove to have a powerful effect on behavior the current paper undertakes an analysis of these programs using a previously unexploited survey of employers we find that both participation in and contributions to voluntary savings plans are significantly higher when employers offer retirement seminars the effect is typically much stronger for non highly compensated employees than for highly compensated employees the frequency of seminars emerges as a particularly important correlate of behavior we are unable to detect any effects of written materials such as newsletters and summary plan descriptions regardless of frequency we also present evidence on other determinants of plan activity
