high frequency analysis of foreign exchange interventions what do we learn abstract the high frequency analysis of foreign exchange dynamics is helpful in order to better identify the impact of central bank interventions evidence robustly shows that interventions do indeed move the exchange rate level in the desired direction interventions increase volatility in the short run as they are regarded as information but they can reduce volatility overall ways of transmission may reach beyond the signalling channel and also include the portfolio balance and a damping channel finally interventions are more successful if they obey certain conditions such as being coordinated among central banks and going with the market and fundamentals

daily effects of foreign exchange intervention evidence from official bank of canada data abstract this paper analyzes the effects of official daily bank of canada intervention in the cad usd exchange rate over the 1995 1998 period using an event study methodology and different criteria for effectiveness some evidence that intervention was systematically associated with both a change in the direction and a smoothing of the exchange rate is presented the results of the analysis however do not suggest that bank of canada intervention succeeded in reducing the volatility of the cad usd exchange rate furthermore the paper shows that the effects of intervention are weakened when adjusting for general currency co movements against the usd

effect of lengthening the school day on mother s labor supply this article examines how a policy oriented toward a specific group within the population can have collateral effects on the economic decisions of other groups in 1996 the chilean government approved the extension of the school day from half to full day school this article exploits the quasi experimental nature of the reform s implementation by time municipality and age targeting of the program in order to examine how the maternal labor supply is affected by the childcare subsidy implicit in the lengthening of the school day using data from the chilean socioeconomic household survey and administrative data from the ministry of education for 1990 2011 the authors estimate that on average there is a 5 percent increase in labor participation and employment rates of single mothers with eligible children between 8 and 13 years old with no younger children who are the group that would be mainly affected by the policy no significant labor supply responses are detected among others mothers with eligible children

foreign exchange market intervention in two small open economies the canadian and australian experience abstract we examine intervention by the bank of canada and the reserve bank of australia for daily data from 1989 to 1998 both central banks intervene in response to excessive exchange rate volatility and uncertainty volatility is the implied volatility of foreign currency futures options uncertainty is the kurtosis of the implied risk neutral probability density functions we also examine the impact of inflation targets unlike other studies we also consider commodity futures prices these turn out to help explain the effectiveness of intervention central bank intervention was largely unsuccessful in both countries though volatility and kurtosis were modestly affected

the effect of pre primary education on primary school performance although the theoretical case for universal pre primary education is strong the empirical foundation is weak in this paper we contribute to the empirical case by investigating the effect of a large expansion of universal pre primary education on subsequent primary school performance in argentina we estimate that one year of preprimary school increases average third grade test scores by 8 percent of a mean or by 23 percent of the standard deviation of the distribution of test scores we also find that preprimary school attendance positively affects student s self control in the third grade as measured by behaviors such as attention effort class participation and discipline

returns to scale at large banks in the us a random coefficient stochastic frontier approach abstract this paper investigates the returns to scale of large banks in the us over the period 1997 2010 this investigation is performed by estimating a random coefficient stochastic distance frontier model in the spirit of tsionas 2002 and greene 2005 2008 the primary advantage of this model is that its coefficients can vary across banks thereby allowing for unobserved technology heterogeneity among large banks in the us we find that failure to consider unobserved technology heterogeneity results in a misleading ranking of banks and mismeasured returns to scale our results show that the majority of large banks in the us exhibit constant returns to scale in addition our results suggest that banks of the same size can have different levels of returns to scale and there is no clear pattern among large banks in the us concerning the relationship between asset size and returns to scale due to the presence of technology heterogeneity

taxes and the timing of births because the tax savings of having a child are a realized only if the birth takes place before midnight january 1 the incentives for the marginal birth are substantial using a sample of children from the national longitudinal survey of youth we find that the probability that a child is born in the last week of december rather than the first week of january is positively correlated with tax benefits we estimate that increasing the tax benefit of having a child by 500 raises the probability of having the child in the last week of december by 26 9 percent

giving children a better start preschool attendance and school age profiles this brief summarizes the giving children a better start preschool attendance and school age profiles in uruguay for the period 1995 the author study the effect of pre primary education on children s subsequent school outcomes by exploiting a unique feature of the uruguayan household survey ech that collects retrospective information on preschool attendance in the context of a rapid expansion in the supply of pre primary places using a within household estimator we find small gains from preschool attendance at early ages that get magnified as children grow up by age 15 treated children have accumulated 0 8 extra years of education and are 27 percentage points more likely to be in school compared to their untreated siblings instrumental variables estimates that attempt to control for non random selection of siblings into preschool lead to similar results pre primary education appears as a successful and cost effective policy to prevent early grade failure and its long lasting consequences in low income countries

conditional covariances and direct central bank interventions in the foreign exchange markets abstract in this paper we investigate the effects of central bank interventions cbis on the ex post correlation and covariance of exchange rates using a multivariate garch model with time varying conditional covariances we estimate the effects of cbis on both the variances and covariance between the yen and the deutsche mark the euro in terms of the us dollar our results suggest that coordinated cbis not only tend to increase the volatility of exchange rates but also explain a significant amount of the covariance between the major currencies we show that this result can be useful for short run currency portfolio management

great expectations and hard times the argentine convertibility plan this paper studies the process that led to the argentine crisis the analysis concentrates on the sequence of public and private decisions together with the varying perceptions and policy incentives that motivated them in the 1990s argentina searched for a new growth trend during much of the period the behavior of agents seemed to be based on the anticipation that current and future incomes could sustain a value of domestic spending much higher than in the past in both real and dollar terms the government was motivated to reinforce those expectations for signaling and political economy reasons the monetary regime not only provided a very visible nominal anchor but also operated as a basic framework for financial contracts mostly denominated in dollars dollar contracting implicitly presumed that the dollar value of incomes would support the servicing of debts despite precautionary actions on the part of the government and the private sector over time an increasing mass of decisions and contracts came to rely on the sustainability of the real exchange rate in the late 1990s exports stopped rising and the foreign supply of credit tightened the economy contracted in the face of these constraints and the solvency of the government was called into question the financial system was vulnerable both in the event of devaluation and in the event of a large deflation cum adjustment convertibility proved to have very large exit costs as was implicit in its design and management

event studies in economics and finance the event study is an important research tool in economics and finance the goal of an event study is to measure the effects of an economic event on the value of firms event study methods exploit the fact that given rationality in the marketplace the effects of an event will be reflected immediately in security prices thus the impact can be measured by examining security prices surrounding the event in this paper event study methods are described including some of the potential complications an example is included to illustrate the approach

measuring banks market power in the presence of economies of scale a scale corrected lerner index abstract a positive lerner index indicates a welfare loss for consumers due to deviations from marginal cost pricing such a welfare loss may not always be due to market power though in particular marginal cost pricing would result in negative profit for the firm in the presence of economies of scale in such a scenario a positive lerner index could simply reflect the firm s need to earn non negative profits rather than market power we propose a novel scale corrected price cost margin for firms that produce in the economies of scale range we show that this measure is more informative about market power than the lerner index itself as an empirical illustration we analyze market power in the u s banking sector using both the corrected and uncorrected lerner index the corrected lerner index reveals significant market power for u s commercial banks during the 2000 2014 period

stabilization of the canadian dollar 1975 1986 the authors extend their earlier work on canadian intervention in the foreign exchange market in three ways 1 use daily data from 1975 to 1986 to see if results for the 1950s hold during the current float 2 extend their original model to include both stock and flow versions of the foreign exchange market and 3 compare estimates using published canadian holdings of u s dollars to estimates using actual intervention which is confidential canadian authorities continue to lean against the wind but their lagged response is longer and more variable published data effectively reflect intervention

children and household economic behavior this paper looks at some of the methodological issues that arise in modeling the effects of children on household behavior and presents some estimates for selected areas for our purposes household behavior will be taken to refer to household decisions on labor supply the allocation of expenditure to different periods and the decision as to what to do with the difference between income and expenditure i shall be concerned mainly with the effects of dependent children and i restrict attention largely to western societies excerpt

bank competition and financial stability in asia pacific the impact of bank competition on financial stability has been a focus of academic and policy debate over the last two decades and particularly since the 2007 08 global financial crises beck 2008 oecd 2011 under the traditional competition fragility view banks cannot earn monopoly rents in competitive markets and this results in lower profits capital ratios and charter values this makes banks less able to withstand demand or supply side shocks and encourages excessive risk taking marcus 1984 alternatively the competition stability view suggests that competition leads to greater stability a less competitive banking market may lead to more risk taking if the big banks are deemed too important to fail and as such obtain implicit or explicit subsidies via government safety nets mishkin 1999 in addition banks with more market power tend to charge higher loan rates which may induce borrowers to assume greater risk leading to greater default in competitive banking markets loan rates are lower too big to fail issues and safety net subsidies are smaller and this results in a positive link between bank competition and stability boyd and de nicolo 2005 it could also be the case as noted by martinez miera and repullo 2010 that bank competition and stability are linked in a non linear manner and in a similar vein berger et al 2009 argue that competition and concentration may coexist and can simultaneously induce stability or fragility

born on the first of july an un natural experiment in birth timing abstract it is well understood that government policies can distort behavior but what is less often recognized is that the anticipated introduction of a policy can introduce its own distortions we study one such introduction effect using evidence from a unique policy change in australia in 2004 the australian government announced that children born on or after july 1 2004 would receive a 3000 baby bonus although the policy was only announced seven weeks before its introduction parents appear to have behaved strategically in order to receive the benefit with the number of births dipping sharply before the policy commenced on july 1 2004 more australian children were born than on any other single date in the past thirty years we estimate that over 1000 births were moved so as to ensure that their parents were eligible for the baby bonus with about one quarter being moved by more than one week most of the effect was due to changes in the timing of induction and cesarean section procedures we find evidence to suggest that babies who were shifted into the eligibility period were more likely to be of high birth weight two years later on july 1 2006 the baby bonus was increased and we find that this again caused births to be moved from june to july these birth timing events represent an opportunity for health researchers to study the impact of planned birthdays and hospital management issues

public child care and mothers labor supply evidence from two quasi experiments abstract public child care is expected to assist families in reconciling work with family life yet empirical evidence for the relevance of public child care to maternal employment is inconclusive we exploit the introduction of a legal claim to a place in kindergarten in germany which was contingent on day of birth cut off dates and resulted in a marked increase in kindergarten attendance of three year olds in the following years instrumental variable and difference in differences estimations on two individual level data sets yield positive effects of public child care on maternal employment a set of placebo treatment tests corroborate the validity of our identification strategies

estimating the effect of financial aid offers on college enrollment a regression discontinuity approach an important problem faced by colleges and universities that of evaluating the effect of their financial aid offers on student enrollment decisions is complicated by the likely endogeneity of the aid offer variable in a student enrollment equation this article shows how discontinuities in an east coast college s aid assignment rule can be exploited to obtain credible estimates of the aid effect without having to rely on arbitrary exclusion restrictions and functional form assumptions semiparametric estimates based on a regression discontinuity rd approach affirm the importance of financial aid as an effective instrument in competing with other colleges for students

childcare effects on maternal employment evidence from chile abstract using a randomized experiment this study examines whether offering afterschool care for children aged between 6 and 13 has an impact on labor market outcomes for women in chile the results show that program participation increases employment by 5 and labor force participation by 7 while the intervention also generates substantial childcare substitution the results also suggest that the provision of afterschool care for older children triggers the use of free daycare for young ineligible children

official central bank interventions and exchange rate volatility evidence from a regime switching analysis in this paper we investigate the effect of central bank interventions on the weekly returns and volatility of the dem usd and yen usd exchange rate returns in contrast with previous analyses we allow for regime dependent specifications and investigate whether official interventions can explain the observed volatility regime switches it is found that depending on the prevailing volatility level coordinated central bank interventions can lead to either a stabilizing or a destabilizing effect our results lead us to challenge the usual view that such interventions always imply increases in volatility c 2002 elsevier b v all rights reserved

public schooling for young children and maternal labor supply as policy makers have sought to reduce the welfare rolls by increasing labor supply among single mothers much attention has been given to the possible role of expanded child care subsidies including direct provision of public preschool at the same time public interest in child care subsidies for two parent households is high for example former vice president gore not long ago proposed to make high quality pre school fully available to every family for every child in every community in america albert gore 1999 in this paper i use 1980 census data to estimate the effect of public school enrollment for a woman s five year old on measures of labor supply and public assistance receipt this approach has two advantages first i am able to estimate the effect of a large implicit child care subsidy 1 second because public kindergarten is universally available to all age eligible children where it is provided selection problems related to means testing do not arise a difficulty with public school enrollment arises because parents may choose to hold their children back a year or enroll them in private school i deal with this issue by using five yearold s quarter of birth qob variables as instruments for public school enrollment status this strategy works because parents ability to enroll a child in public kindergarten in the academic year when the child turns five typically depends on the calendar date of the child s birth 2 in most states children born in the second quarter april 1 june 30 of 1974 will have been eligible to start kindergarten in the fall of 1979 while children born in the first quarter january 1march 31 of 1975 generally will not eligibility for children born between july 1 and december 31 1974 depends on the rules where they live 3

preschool and maternal labour market outcomes evidence from a regression discontinuity design in developing countries employment rates for mothers with young children are relatively low this study analyzes how maternal labor market outcomes in argentina are affected by the preschool attendance of their children using pooled household surveys we show that 4 year olds with birthdays on june 30 have sharply higher probabilities of preschool attendance than children born on july 1 given enrollment age rules regression discontinuity estimates using this variation suggest that preschool attendance of the youngest child in the household increases the probability of full time employment and weekly hours of maternal employment we find no effect of preschool attendance on maternal labor outcomes for children who are not the youngest in the household

efficiency technical change and returns to scale in large us banks panel data evidence from an output distance function satisfying theoretical regularity abstract this paper provides parametric estimates of technical change efficiency change economies of scale and total factor productivity growth for large banks those with assets in excess of 1 billion in the united states over the period from 2000 to 2005 this is done by estimating an output distance function subject to theoretical regularity within a bayesian framework we find that failure to incorporate theoretical regularity conditions results in mismeasured shadow revenue and or cost shares which in turn leads to perverse conclusions regarding productivity growth our results from the regularity constrained model show that total factor productivity of the large us banks grew at an average rate of 1 98 over the sample period however our estimates also show a clear downward trend in the growth rate of total factor productivity and our decomposition of the primal divisia total factor productivity growth index into its three components technical change efficiency change and economies of scale indicates that technical change is the driving force behind this decline

early kindergarten maternal labor supply and children s outcomes evidence from italy abstract we analyze a reform that introduced early access to subsidized childcare for 2 year old children in italy exploring the effects on several measures of maternal labor supply and on children s cognitive outcomes our identification strategy exploits discontinuities in the eligibility rules and the staggered implementation of the reform we find that the policy increased mothers participation in the labor market and lowered the reservation wage of the unemployed thus increasing their likelihood of finding a job at the same time the newly introduced childcare arrangement did not affect children s cognitive development irrespective of their family background
