what explains recent changes in international monetary policy attitudes toward inflation evidence from developed countries abstract this paper identifies source s contributing to the recent international shift in monetary policy attitudes toward inflation data from 18 developed countries suggests that this shift is connected to the universal increase in policy responses to economic openness in the 1990s

evaluating welfare reform in the united states this paper reviews the economic literature on welfare reform over the 1990s a brief summary of the policy changes is followed by a discussion of the methodological techniques that analyze the effects of these changes on outcomes the paper then critically reviews the econometric and experimental literature on caseload changes labor force changes poverty and income changes and family formation changes a growing body of evidence suggests that recent policy changes have influenced economic behavior and well being one particular set of new style welfare programs seems to show especially promising results with significantly increased work and earnings and reduced poverty

some empirical evidence on the effects of shocks to monetary policy on exchange rates this paper investigates the effects of shocks to u s monetary policy on exchange rates we consider three measures of these shocks orthogonalized shocks to the federal funds rate orthogonalized shocks to the ratio of nonborrowed to total reserves and changes in the romer and romer index of monetary policy in sharp contrast to the literature we find substantial evidence of a link between monetary policy and exchange rates specifically according to our results a contractionary shock to u s monetary policy leads to i persistent significant appreciations in u s nominal and real exchange rates and ii significant persistent deviations from uncovered interest rate parity in favor of u s interest rates

real exchange rate volatility and economic openness theory and evidence this paper relates the volatility of the trade weighted effective real exchange rate to the degree of trade openness of an economy the theoretical part presents an intertemporal monetary model of a small open economy with nominal rigidities both monetary and aggregate supply shocks are shown to produce ceteris paribus smaller real exchange rate movements if the country is more open to foreign trade empirical evidence on a cross section of forty eight countries confirms this relationship differences in trade openness explain a large part of the cross country variation in the volatility of the effective real exchange rate

multiple experiments for the causal link between the quantity and quality of children this article presents evidence on the child quantity child quality trade off using quasi experimental variation due to twin births and preferences for a mixed sibling sex composition as well as ethnic differences in the effects of these variables our sample includes groups with very high fertility an innovation in our econometric approach is the juxtaposition of results from multiple instrumental variables strategies capturing the effects of fertility over different ranges for different sorts of people to increase precision we develop an estimator that combines different instrument sets across partially overlapping parity specific subsamples our results are remarkably consistent in showing no evidence of a quantity quality trade off

openness central bank independence and the sacrifice ratio traditional explanations of the negative correlation between openness and inflation presume that an inverse relationship between the degree of openness and the sacrifice ratio reduces the inflation bias of descretionary monetary policy temple 2002 concludes however that such a relationship fails to emerge in cross country data our analysis of the same cross country data considered by temple indicates that once the degree of central bank independence and its interaction with greater openness and the sacrifice ratio in addition increased openness lessens the positive effect of central bank independence on the sacrifice ratio

does greater trade openness reduce inflation further evidence using panel data techniques abstract in this article we estimate the relation between inflation and trade openness q j econ 108 1993 869 the higher the gains in terms of product in generating an inflationary surprise the greater the incentives will be for the government to effect such a surprise

introducing household production in collective models of labor supply in a recent paper chiappori 1992 i proposed a model of labor supply based on a collective representation of household behavior in this framework each household member is characterized by his or her own utility function and decisions are only assumed to result in pareto efficient outcomes i showed that these simple assumptions were sufficient to i generate testable restrictions on labor supply functions and ii recover individual preferences and the outcome of the decision process from observed behavior for the sake of simplicity the results were derived in the simplest possible case namely a static labor supply model with private consumptions such a framework was appropriate only for the purpose of the paper that is a preliminary exploration of the properties of collective models of labor supply the next step is to evaluate the robustness of the results to various extensions of the basic model this opens a general research program and generates a wide range of particular problems that it is hoped will be considered in the future among the most serious shortcomings of the 1992 model is the absence of household production as in most labor supply models agents were assumed to divide their time between market activities and leisure as apps and rees 1997 in this issue very rightly point out in their comment the absence of domestic production is far from innocuous as soon as welfare issues are considered for instance a low level of market labor supply will automatically be interpreted as a large consumption of leisure whereas it may in fact reflect the specialization of one of the members in domestic

explaining peak inflation rates prior to disinflationary policy adjustments or what got us into this mess this study investigates using annual data from 1974 2004 whether unionization rates trade openness and central bank independence can help explain cross national and inter temporal variations in level of peak inflation prior to a disinflationary policy adjustment i find that unionization is positively associated with both peak inflation rates whereas more independent central banks and trade openness are correlated with lower inflation levels these results are robust to controlling for the high inflation decade of the 1970s and to using average rather than peak inflation as the explanatory variable

openness and inflation a general equilibrium model of a small open economy is developed to analyse the optimal rate of inflation under discretion once agents welfare is the sole policy objective it is possible to show that openness and inflation no longer have a simple inverse relationship a greater degree of openness may lead the policy maker to want to exploit the short run phillips curve more aggressively even if involves a smaller short run benefit because changes in export demand affect the terms of trade inflation can then be higher in a more open economy

testing commitment models of monetary policy evidence from oecd economies in ation rates in a number of oecd follow a common trend over the past four decades in ation starts out low in the 1960s rises for a time before peaking in the 1970s or early 1980s and then falls back to initial levels this similarity in the behavior of trend in ation suggests that any explanation of long run in ation trends ought to apply across oecd countries ireland 1999 shows that a simple time inconsistency model of monetary policy modifled to allow for a time varying nairu can explain long run trends in u s in ation in this paper we show that this result cannot serve as an explanation of the common trend in oecd in ation as it flts the data only in the u s we investigate two important variants of the hypothesis i that time inconsistency was an important component of central bank behavior in earlier decades but has become less signiflcant in recent years and ii that time inconsistency problems drive u s in ation which afiects in ation rates in other countries as a result of central bankers attempts to manage nominal exchange rate movements vis a vis the u s dollar we flnd that the flrst hypothesis flts the data no better than the baseline model we flnd some support for the international spillovers version of the model but the behavior of non u s central bankers with respect to domestic unemployment rates is not well described by the time inconsistency mechanism

is universal child care leveling the playing field abstract we assess the case for universal child care programs in the context of a norwegian reform which led to a large scale expansion of subsidized child care we use non linear difference in differences methods to estimate the quantile treatment effects of the reform we find that the effects of the child care expansion were positive in the lower and middle parts of the earnings distribution of exposed children as adults and negative in the uppermost part we complement this analysis with local linear regressions of the child care effects by family income we find that most of the gains in earnings associated with the universal child care program relate to children of low income parents whereas upper class children actually experience a loss in earnings in line with the differential effects by family income we estimate that the universal child care program substantially increased intergenerational income mobility to interpret the estimated heterogeneity in child care effects we examine the mediating role of educational attainment and cognitive test scores and show that our estimates are consistent with a simple model where parents make a tradeoff between current family consumption and investment in children taken together our findings could have important implications for the policy debate over universal child care programs suggesting that the benefits of providing subsidized child care to middle and upper class children are unlikely to exceed the costs our study also points to the importance of universal child care programs in explaining differences in earnings inequality and income mobility across countries and over time

evaluating the effects of childcare policies on children s cognitive development and maternal labor supply to explore the role of childcare policies in the development of early cognitive skills this paper jointly estimates a cognitive achievement production function and a dynamic discrete choice model of maternal labor supply and childcare decisions using counter actuals from the model i investigate how the designs of two childcare programs head start and childcare subsidies affect the formation of cognitive skills through maternal work and childcare decisions the results suggest large impacts on cognitive skills from expanding head start to current noneligibles and negligible impacts of subsidies on cognitive skills of current eligibles abstract from author

openness and inflation a new assessment romer 1993 uses a barro gordon type model to argue that openness puts a check on the government s incentive to engage in unanticipated inflation because of induced exchange rate depreciation 2 therefore in the absence of precommitment in monetary policy more open economies will tend to have lower inflation rates romer finds that empirically over a large sample of countries and over a broad time frame average inflation rates are lower in smaller more open economies this relationship is significant quantitatively large and robust moreover these findings suggest that models in which the absence of precommitment in monetary policy leads to inefficiently high average levels of inflation are essential to understanding inflation in most of the world this comment suggests that the negative link between inflation and openness romer found may be largely driven by the responses of severely indebted countries sics to the debt crisis of the 1980s figures i and ii show the scatterplots of the logarithms of average inflation and openness for the subperiods 1973 to 1981 predebt crisis and 1982 to 1990 the debt crisis period different groups of countries are separated according to their indebtedness level 3 the solid lines in the figures represent the predicted value of inflation obtained from a regression of openness on inflation for the countries in each group as the scatterplots show there is indeed a strong negative relation between openness and inflation among sics during the debt crisis

a note on romer s openness inflation relation the responsiveness of as and ad to economic openness and monetary policy temple 2002 empirically challenges romer s 1993 negative openness inflation relation on empirical grounds this article links economic openness to the slopes of aggregate supply as and aggregate demand ad to explain why the openness inflation relation can be ambiguous starting with a widely used assumption initiated by romer 1993 that more open economies face greater output inflation tradeoffs we demonstrate that greater output inflation tradeoffs in more open economies reflected in the steeper as induce policymakers to adopt more aggressive optimal monetary policy reflected in the flatter ad empirical results from 15 developed countries data support our theoretical explanation on the recent empirical failure in finding the negative openness inflation relation

bargaining and distribution in marriage the standard economic model of the family is a common preference model that assumes that a family maximizes a single utility function and implies that family behavior is independent of which individuals receive income or control resources in recent years this model has been challenged by game theoretic models of marriage that do not impose pooling and are therefore consistent with empirical evidence that income controlled by husbands and wives does have different effects on family behavior in this paper the authors review a number of simple bargaining models and relevant empirical evidence and discuss their implications for distribution within marriage

economic status and health in childhood the origins of the gradient the well known positive association between health and income in adulthood has antecedents in childhood not only is children s health positively related to household income but the relationship between household income and children s health becomes more pronounced as children age part of the relationship can be explained by the arrival and impact of chronic conditions children from lower income households with chronic conditions have worse health than do those from higher income households the adverse health effects of lower income accumulate over children s lives part of the intergenerational transmission of socioeconomic status may work through the impact of parents income on children s health

openness exchange rate regimes and the phillips curve abstract recent research suggests that the phillips curve slope measured using sacrifice ratios from the period 1961 88 is positively related to trade openness contradicting the romer 1993 openness and inflation theory and evidence quarterly journal of economics 108 869 903 hypothesis that disinflations are less costly in open economies in this paper i consider sacrifice ratios and output inflation trade offs from 1981 98 and allow their dependence on openness to vary with the exchange rate regime sacrifice ratios are weakly negatively related to openness but the strength of the relationship does not increase with exchange rate flexibility output inflation trade offs are negatively related to openness and the strength of the relationship increases with exchange rate flexibility

money for nothing universal child care and maternal employment abstract the strong correlation between child care and maternal employment rates has led previous research to conclude that affordable and readily available child care is a driving force both of cross country differences in maternal employment and of its rapid growth over the last decades we analyze a staged expansion of subsidized child care in norway our precise and robust difference in differences estimates reveal that there is little if any causal effect of subsidized child care on maternal employment despite a strong correlation instead of increasing mothers labor supply the new subsidized child care mostly crowds out informal child care arrangements suggesting a significant net cost of the child care subsidies

exchange rate pass through openness and the sacrifice ratio abstract considerable recent work has reached mixed conclusions about whether and how globalization affects the inflation output trade off and suggests that the ultimate effect of openness on the output inflation relationship is influenced by a variety of factors in this paper we consider the impact of exchange rate pass through and examine how pass through conditions the effect of openness on the sacrifice ratio we develop a simple theoretical model showing how the extent of both pass through and openness can interact to influence the output inflation relationship next we empirically explore the nature of these two variables and their interaction results indicate that greater pass through increases the sacrifice ratio that there is statistically significant interaction between pass through and openness and once the extent of pass through is taken into account alongside other factors that affect the sacrifice ratio such as central bank independence openness fails to exert an empirically robust effect on the sacrifice ratio

do husbands and wives pool their resources evidence from the united kingdom child benefit common preference models of family behavior imply income pooling a restriction on family demand functions such that only the sum of husband s income and wife s income affects the allocation of goods and time testing the pooling hypothesis is difficult because most family income sources are not exogenous to the allocations being analyzed in this paper we present an alternative test based on a natural experiment a policy change in the united kingdom that transferred a substantial child allowance to wives in the late 1970s using family expenditure survey data we find strong evidence that a shift toward greater expenditures on women s clothing and children s clothing relative to men s clothing coincided with this income redistribution

low skilled immigration and parenting investments of college educated mothers in the united states evidence from time use data this paper uses several decades of u s time diary surveys to assess the impact of low skilled immigration through lower prices for commercial childcare on parental time investments using an instrumental variables approach that accounts for the endogenous location of immigrants we find that low skilled immigration to the united states has contributed to substantial reductions in the time allocated to basic childcare by college educated mothers of nonschool aged children however these mothers have not reduced the time allocated to more stimulating educational and recreational activities with their children understanding the factors driving parental time investments on children is crucial from a child development perspective

does globalisation discipline monetary policymakers abstract this paper analyses globalisation using a small general equilibrium model it concludes that whether increased openness a reduction in the costs of international trade helps to discipline monetary policy in large open economies depends on the type of trade costs moreover to the extent that globalisation induces stronger competition in the goods market this may also have an adverse effect on monetary policy discipline the latter is due to international expenditure switching which becomes a more forceful channel as competition intensifies thus the answer to the question in the title is not necessarily affirmative

international dimensions of obesity and overweight related problems an economics perspective obesity is a growing concern new world health organization who figures indicate that obesity is spreading around the world as a global epidemic according to the who there are more people suffering from overweight related problems than malnutrition globally there are more than 1 billion adults who are overweight and at least 300 million of them are clinically obese while 800 million suffer from malnutrition who 2004 the economic costs due to obesity can be burdensome currently in the united states medical costs associated with obesity and smoking account for about 9 each of all health expenditures finkelstein fiebelkorn and wang u s obesity attributable medical expenditures reached 75 billion in 2003 obesity however is important not only from an economic perspective but also from a social perspective the social consequences of obesity are serious and multiple studies have shown that obesity affects in a negative and statistically significant way personal and working relations earnings and wages particularly for females cawley overall obesity is a complex phenomenon several recent economic studies have explored the role of different cultural and sociodemographic factors on obesity rates leaving genetics aside obesity is caused by the consumption of too many calories and or low expenditures of calories i e low physical activity consequently most published economic research provided a justification for the increased growth of obesity rates by analyzing several factors that may contribute to this imbalance of caloric consumption and usage see chou grossman and saffer cutler glaeser and shapiro lakdawalla and philipson philipson and posner there are mainly two arguments that could justify the growth of overweight problems around the world some researchers argue that obesity growth is mainly due to a higher intake of calories while others state that obesity is mainly caused by a lower expenditure of caloies in daily activities in line with the calorie consumption argument cutler glaeser and shapiro stated that americans have become more obese over the past twenty five years primarily due to the consumption of more calories analyzing changes in food consumption between the mid 1970s and the mid 1990s for

maquiladoras and market mamas women s work and childcare in guatemala city and accra abstract this paper analyses work childcare and earnings of mothers in the slums of guatemala city and accra similar factors affect decisions to work and to use formal daycare but the importance of childcare varies with the role of the formal labour sector in guatemala where formal sector work is important higher prices for informal care increase formal daycare use however daycare prices and proximity to daycare centers do not significantly affect earnings in guatemala city and accra respectively providing formal daycare may be more important to mothers decision to work in cities where formal sector work dominates

a new assessment of openness and inflation reply terra 1998 argues that my finding romer 1993 of a negative relationship across countries between openness and inflation is actually caused by the severely indebted countries over the debt crisis period she proposes an explanation of the openness inflation relationship based on indebted countries need to raise revenue to repay their debts the smaller a country s trade share the more depreciated the real value of the currency must be in order to generate a given trade surplus as a share of gdp and the more depreciated the currency the greater the pressure on the government s budget and thus the greater pressure to inflate in contrast in my paper i argue that the relationship stems from imperfect commitment in monetary policy the less open the economy the greater the benefits of surprise inflation and thus the higher the level of inflation in the absence of complete commitment terra has uncovered interesting variation in the opennessinflation relationship across countries and over time nonetheless i want to make three brief points that suggest that the channel she proposes accounts for only a modest part of the overall relationship first terra s results do not justify her claim that the relationship is a product only of the severely indebted countries sics during the debt crisis this can be seen from her table i for the sics the openness inflation link in the precrisis period though weaker than during the crisis is large and statistically significant the estimates for the moderately indebted countries although imprecise suggest a relationship that is very similar to that for the sics in both periods and for the less indebted countries the point estimates again suggest a negative relationship indeed for the full sample period the coefficient on openness is significantly different from zero only for the high income countries terra s all other countries is there no evidence of a negative association between openness and inflation

openness inflation and the phillips curve a puzzle models of open economies with nominal rigidities are often thought to predict a correlation between openness to trade and the slope of the output inflation trade off or phillips curve using a variety of measures of the trade off and a standard measure of openness this paper argues that the direct evidence for a correlation is not strong in turn this calls into question the usual explanation for the negative correlation between openness and inflation that was documented by romer 1993 the paper considers some alternative explanations for the romer evidence

trade openness and inflation the role of real and nominal price rigidities the paper revisits the long standing question of the impact of trade openness on the inflation output trade off by accounting for the effects of product market competition on price flexibility the study develops a new keynesian open economy dynamic stochastic general equilibrium model with non constant price elasticity of demand and calvo price setting in which the frequency of price adjustment is endogenously determined it demonstrates that trade openness has two opposing effects on the sensitivity of inflation to output fluctuations on the one hand it raises strategic complementarity in firms pricing decisions and the degree of real price rigidities which makes inflation less responsive to changes in real marginal cost on the other hand it strengthens firms incentives to adjust their prices thereby reducing the degree of nominal price rigidities and increasing the sensitivity of inflation to changes in marginal cost the study explains the positive relationship between competition and the frequency of price adjustment observed in the data it also provides new insights into the effects of global economic integration on the phillips curve

household food expenditures parental time allocation and childhood overweight an integrated two stage collective model with an empirical application and test this article develops a two stage collective household production model for household food expenditures parental time allocation and childhood overweight the model fills four gaps in the literature i the black box treatment of intrahousehold decision making ii exclusion of the child s decision input iii exclusion of noneconomic variables and iv absence of theory supported instrument identification the traditional unitary household production model with children is a special case of the model developed using a unique data set the unitary model is rejected there are important differences in the policy implications to be drawn from both models based on the data set used

the effects of time limits the eitc and other policy changes on welfare use work and income among female headed families of all of the welfare reforms that were implemented during the 1990s time limits may represent the single greatest break from past policy this paper expands on what is known about this important welfare reform measure by exploiting the predictions from grogger and michalopoulos 2003 to estimate the effects of time limits on welfare use employment labor supply earnings and income among female headed families results based on data from the march current population survey suggest that time limits have had important effects on welfare use and work accounting for about one eighth of the decline in welfare use and about 7 of the rise in employment since 1993 they have had no significant effect on earnings or income however the analysis also shows that the collective effects of other reforms have had important impacts on employment and labor supply furthermore it identifies the earned income tax credit eitc as a particularly important contributor to both the recent decrease in welfare use and t

child care costs as a barrier to employment for single and married mothers because women typically serve as primary care providers for their children female labor force participation behavior is likely to be affected significantly by the costs associated with replacing maternal care with nonmaternal care while some evidence of this phenomenon exists in the economics literature discrepancies across studies make it difficult to provide conclusive evidence of the employment effects of these child care costs this paper uses an improved sipp survey design to present new evidence regarding the degree to which child care prices impede mothers employment behavior with additional evidence of the difference in these elasticities across marital status empirical technique and equation specification this permits linking this paper to the existing evidence drawing the conclusion that child care prices impede mothers employment behavior significantly with single mothers exhibiting less responsiveness in their labor force participation behavior to child care price changes than marri

the effect of child care costs on married women s labor force participation the effect of child care costs on the probability that married women with children will participate in the labor market is examined child care costs are estimated using a generalized tobit specification corrected for selection estimates of a structural probit model of labor force participation provide evidence to support the prediction that increased child care costs lower the probability of participation it is also shown that the lower rate of labor force participation among mothers of preschoolers is entirely the result of the higher child care costs faced by these women and endogeneity of the number of young children in the participation equation copyright 1992 by mit press

equilibrium real exchange rate volatility and stabilization abstract this paper is composed of two parts the theoretical part studies the effect of real exchange rate rer volatility on trade using a general equilibrium framework the volatility of the rer is derived endogenously and is caused by a demand shock which may be influenced by inflation volatility the model shows that rer volatility affects positively the equilibrium rer in the empirical part the behavior of several rer volatility indexes over the last fifteen years for brazil is examined identifying the influence of stabilization plans and inflation volatility in fact inflation volatility explains most of the variation in rer volatility in brazil in addition export supply equations that include rer volatility as one of the explanatory variables are estimated for brazil for most specifications the rer volatility coefficient is negative although not significantly different from zero the implied elasticity for the most significant rer volatility coefficient is 0 05

child care subsidies quality of care and the labor supply of low income single mothers the authors examine the effects of child care subsidies on the labor supply decisions of low income mothers and o n the quality of care their children receive using newly gathered data on two programs that subsidize the child care expenditures of families in kentucky they find that single mothers who receive child care subsidies are more likely to be employed and are generally more satisfied with the care their children receive but subsidies have little effect on hours worked copyright 1992 by mit press

does compulsory school attendance affect schooling and earnings we establish that season of birth is related to educational attainment because of school start age policy and compulsory school attendance laws individuals born in the beginning of the year start school at an older age and can therefore drop out after completing less schooling than individuals born near the end of the year roughly 25 percent of potential dropouts remain in school because of compulsory schooling laws we estimate the impact of compulsory schooling on earnings by using quarter of birth as an instrument for education the instrumental variables estimate of the return to education is close to the ordinary least squares estimate suggesting that there is little bias in conventional estimates every developed country in the world has a compulsory schooling requirement yet little is known about the effect these laws have on educational attainment and earnings 1 this paper exploits an unusual natural experiment to estimate the impact of compulsory schooling laws in the united states the experiment stems from the fact that children born in different months of the year start school at different ages while compulsory schooling laws generally require students to remain in school until their sixteenth or seventeenth birthday in effect the interaction of school entry requirements and compulsory schooling laws compel students born

openness the sacrifice ratio and inflation is there a puzzle abstract the standard time inconsistency based explanation for the negative correlation between openness and inflation requires an inverse relationship between the sacrifice ratio and openness but daniels et al 2005 openness central bank independence and the sacrifice ratio journal of money credit and banking 37 2 371 379 have provided evidence that controlling for central bank independence reveals a positive relationship this paper embeds the time inconsistency approach within a model of a multisector imperfectly competitive open economy in this setting greater openness raises the sacrifice ratio but reduces the inflation bias thus failure to observe an inverse relationship between openness and the sacrifice ratio does not necessarily imply that the time inconsistency approach is irrelevant to understanding the openness inflation relationship

employment of new mothers and child care choice differences by children s age working women frequently withdraw from the formal labor market for a period of time following their 1st birth while more than 1 3 of these mothers return to work within 3 months 1 2 remain out of formal employment 2 years after giving birth this paper examines the determinants of womens return to the labor market within 2 years of childbirth and the type of child care women choose employing data from the national longitudinal survey of youth the study found economic incentives to have powerful effects upon mothers work behavior despite cultural norms which may encourage mothers to care for their very young children mothers wages and other family income were important determinants the relationship between child care costs and work and child care choice change as children age with mothers being most sensitive to the psychic and financial costs of care in the months immediately following childbirth specifically the presence of mothers personal wages relates positively to early return to work and higher family income delays return to work greater child care tax credits increase the return to work within 3 months yet have little effect on later labor supply neither wages income nor tax credits significantly affected child care choice overall financial variables had less impact on type of child care than on the decision to work

collective household models principles and main results in the traditional approach to consumer behaviour it is assumed that households behave as if they were single decision making units this approach has methodological empirical and welfare economic deficiencies a valuable alternative to the traditional model is the collective approach to household behaviour the collective approach explicitly takes account of the fact that multi person households consist of several members which may have different preferences among these household members an intrahousehold bargaining process is assumed to take place in addition to providing an introduction to the collective approach this survey intends to show how different collective household models each with their own aims and assumptions are connected

testing monetary policy intentions in open economies 1 introductionthis article examines the relationship between economic openness and inflation performance among the most prominent research on this topic is the work by romer 1993 he demonstrates a negative relationship between economic openness and the inflation level his finding has also been viewed as supportive albeit indirectly of time consistency theory kydland and prescott 1977 1 romer 1993 argues that policymakers in more open economies have less incentive to adopt an expansionary monetary policy his argument is based on the assumption that monetary surprises in more open economies result in higher inflation for a given increase in output romer s finding that more open economies have lower inflation levels leads him to infer that this is evidence of time consistency in monetary policy practices however romer s work has not been generally accepted temple 2002 provides evidence that the openness inflation correlation does not stem from time consistency theory because the inflation level may not properly reveal the monetary authorities policy intentions temple questions this inference because it starts from a strong but unjustified assumption more open economies possess a relatively steeper phillips curve consequently temple proposes that the examination of the positive relationship between openness and the slope of the phillips curve is a fundamental condition for romer s argument he however finds little support for the positive relationship between economic openness and the slope of the phillips curve further work on the relationship of openness and monetary policy intentions comes from clarida gali and gertler 2001 2002 hereafter cgg in cgg 2001 the authors present a simple open economy model with a taylor type interest rate policy rule taylor 1993 the article concludes that the optimal monetary policy in an open economy has the same solution as that in a closed economy derived in cgg 1999 the authors also suggest that there is a direct link between the degree of economic openness and the aggressiveness of monetary policy they state that o penness does affect the parameters of the model suggesting a quantitative implication h ow aggressively a central bank should adjust the interest rate in response to inflationary pressures depends on the degree of openness cgg 2001 p 248 in subsequent work cgg 2002 revisit the issue based on a dynamic open economy new keynesian model and the role of monetary policy in open economies is refined consistent with the argument in cgg 2001 they find that the optimal monetary policy rule in an open economy is isomorphic to that in a closed economy in the nash equilibrium they also suggest that openness does not affect the optimality of a policy rule in such a scenario on the other hand economic openness does affect optimal monetary policy when the foreign optimal policy is endogenous in the domestic country s objective function this effect however is ambiguous in direction because the relationship between the degree of economic openness and the aggressiveness of monetary policy is determined by the relative size of trade and wealth effects of changes in foreign output this line of theoretical literature is limited and does not offer a definitive conclusion on the relationship between economic openness and monetary policy intentions our article provides an alternative empirical evaluation of the relationship based on prior literature we use inflation variability and persistence as the measures of monetary policy intentions one branch of the literature such as taylor 1999 cgg 2000 and owyang 2001 argues that aggressive monetary policy reduces the volatility of inflation for instance cgg 2000 estimate a forward looking taylor rule for the period between 1960 i and 1996 iv they use paul volcker s appointment as chairman of the federal reserve system as a regime shift to a more aggressive anti inflation policy stance

child support welfare dependency and women s labor supply this study evaluates the potential effectiveness of alternative child support policies in reducing welfare program participation employing longitudinal data from the panel study of income dynamics the analysis addresses the simultaneity of women s decisions regarding welfare participation labor force participation and annual hours of work following marital breakup the estimation framework accounts for the endogeneity of child support payments with female labor supply and for the selection bias due to differential rates of remarriage among divorced separated women results show that higher child support payments would i decrease welfare participation and ii increase average hours of work the empirical estimates are used to assess the potential effects of adopting alternative child support policies such as the wisconsin child support assurance system these results suggest that large potential welfare cost savings are attainable but significant reductions in welfare participation rates would only be achieved through substantial improvements in child support enforcement or through government assured child support payments

how has globalisation affected inflation in china this paper investigates how globalisation has affected inflation in china we estimated standard phillips curve inflation equations and examined whether globalisation has affected the structure of inflation dynamics as captured by the phillips curve empirical results suggest that the globalisation of the chinese economy has changed the behaviour of inflation dynamics in particular the impact of domestic and global output gaps on domestic inflation in china has changed significantly since 1994 before 1994 the domestic output gap was a major factor in driving domestic inflation after 1994 however the global output gap plays a significant and more important role in affecting domestic inflation the finding implies that chinese monetary authorities should specifically take into account the developments in global output in their monetary policymaking process

monetary policy games inflationary bias and openness abstract when a country s central bank has higher output objectives than those of wage setters the noncooperative nash equilibrium contains an inflationary bias which is higher the flatter the economy s aggregate supply curve an economy s openness from the input side is an exogenous observable characteristic that provides a direct way of testing the theory when the imported intermediate goods displace capital labor in production a higher degree of openness flattens steepens the economy s aggregate supply curve and increases decreases the inflationary bias

the demand for quality in child care we estimate a model of demand for quality related attributes of child care group size staff child ratio and provider training the model is estimated jointly with equations for mode expenditure on and hours of care and the mother s labor supply the results show that a lower price of child care in a particular mode leads to substitution toward that mode and an increase in the use of paid child care a decrease in the price of care causes an increase in hours of care demanded and a decrease in the demand for qualityrelated attributes income effects on demand for quality are small

globalization the output inflation tradeoff and inflation abstract this paper provides comprehensive evidence on the relation between inflation and globalization defined here as trade and financial openness using a large cross section of 91 countries over the period 1985 2004 we establish two main empirical regularities both higher trade and financial openness i reduce central banks inflation bias yielding lower average inflation and ii are associated with a larger output inflation tradeoff this evidence is at odds with the standard barro gordon framework which would require globalization to have a negative effect on the output inflation tradeoff to yield lower equilibrium inflation but it is consistent with a recent strand of new keynesian models emphasizing the role of imperfect competition and nominal rigidities our findings also support the relevance of the time inconsistency hypothesis which underlies the theoretical models predicting a relation between globalization and inflation for the oecd subsample however we do not find an effect of openness on inflation the output inflation tradeoff suggesting that these countries have created an institutional framework for central banks that eliminates distortions due to the time inconsistency problem

the theory and econometrics of health information in cross sectional nutrient demand analysis understanding the role of health information in food and nutrient demand has become an important issue over the last decade endogeneity and measurement error are two empirical problems that are inherent in this type of analysis while some type of instrumental variables estimation would appear the obvious solution this article provides several theoretical and empirical reasons why this is not the case in cross sectional analysis an alternative estimation strategy is pursued an empirical example is given and the implications are discussed copyright 2001 oxford university press

a new measure of trade openness trade openness popularly measured as x m gdp in the hundreds of studies published to date consistently considers the world s biggest trading countries such as the usa the uk japan and germany to be closed economies irrespective of the data set used this study suggests a composite trade share measure that more completely reflects reality by combining two important dimensions of trade openness trade share and the relative importance of a country s trade level to total world trade robustness tests support the new proposed measure in lieu of the conventional measure of openness and suggest that the latter may not only be incomplete but may also overstate the impact of trade on such things as income and the environment

the causes of childhood obesity a survey childhood obesity rates are rapidly rising in many countries since it is highly likely that obesity will persist into adulthood current rates undermine the health and future of people in developed as well as developing countries this public health epidemic carries significant economic social as well as individual level consequences and has become a research topic of significant interest for various disciplines including economics we survey the literature in economics and related disciplines associated with the causes of childhood obesity and synthesize the results to provide a better understanding of the explanations for the rising childhood obesity rates this is an important step in crafting effective policies to combat global childhood obesity trends

children and their parents labor supply evidence from exogenous variation in family size although theoretical models of labor supply and the family are well developed there are few credible estimates of key empirical relationships in the work family nexus this study uses a new instrumental variable the sex composition of the first two births in families with at least two children to estimate the effect of additional children on parents labor supply in the united states instrumental variables estimates using the sex mix are substantial but smaller than the corresponding ordinary least squares ols estimates moreover unlike the ols estimates the female labor supply effects estimated using sex mix instruments appear to be absent among more educated women and women with high wage husbands we also find that married women who have a third child reduce their labor supply by as much as women in the full sample while there is no relationship between wives child bearing and husbands labor supply excerpt

the significance and insignificance of demand analysis in evaluating promotion programs the estimated effects of promotion on demand are often small and insignificant yet the estimated effects of promotion on industry profit are often positive and large this puzzle is explained by demonstrating that in significance of promotion in a demand equation does not imply and is not implied by in significance of promotion in an industry profit equation a monte carlo example is provided the econometric modeling implications are discussed the short run marginal effect of a dollar of generic beef promotion on slaughter cattle industry profit is estimated to be about 9 84 with a standard error of 3 77 for 1997 the 1996 farm bill requires that check off based commodity promotion programs be evaluated at least once every five years this legislation has increased the interest in the effects of commodity promotion programs a

inflation in open economies abstract this paper relates the time consistent inflation rate to the degree of trade openness of an economy the mechanism linking the welfare effects of monetary surprises and hence the incentives to inflate to openness does not rely on a large country terms of trade effect but rather is due to imperfect competition and nominal price rigidity in the non traded sector the empirical evidence supports the main predictions of the model 1997 elsevier science b v

trade openness and inflation episodes in the oecd boschen and weise journal of money credit and banking 2003 model the probability of a large upturn in inflation in the oecd an inflation start we extend their work to consider the impact of trade openness on the probability of such an event the main finding is that increased openness reduces the probability of an inflation start both directly and indirectly through restricting the role of general elections in triggering inflation starts

child care costs and family labor supply this paper presents a theoretical and empirical analysis of the effects of child care costs on family labor supply and the demand for market child care the model is a framework for cross section estimation of the effects of child care costs on labor supply and child care use it applies to households having young children requiring continuous care and in which both the mother and 1 other potential child care provider are present the 3 potential sources of child care are the mother the potential informal provider and the market using data from the 1980 baseline household survey of the employment opportunity pilot projects this empirical analysis uses a subsample of 6170 households in which there is a married woman under age 45 with her spouse present at the time of the survey at least 1 child under age 14 and nonmissing data on key variables results show that 1 higher market child care costs discourage women from working even when an informal source of care is available indicating that such informal care is an imperfect substitute for market care 2 a higher wage rate for the mother encourages her to work thus a higher wage rate increases the probability of using market child care 3 the number of children requiring care has a negative impact on the probability of the women working with the largest impact caused by younger children 4 nonwage income has a negative impact on the probability of the woman working and 5 black women are more likely to work than whites and are statistically more likely than whites to use market child care if they do work this family labor supply model predicts that the cost of market child care will affect household decisions on labor supply and child care use estimates of a qualitative choice model provide strong confirmation that child care costs affect such decisions the responsiveness of the labor supply of mothers to child care costs demonstrated in this study indicate that such subsidies do have their intended effect of encouraging labor supply the fact that a large proportion of current child care subsidies benefit primarily middle and upper income families via the income tax credit suggests that the labor supply effets of such subsidies may in practice be stronger for less needy families than for low income families employer subsidized child care may become an increasingly popular tool for attracting mothers into the labor force

a structural model of labor supply and child care demand this paper specifies and estimates a structural model in which the decision to purchase market child care and the quality purchased is made simultaneously with the employment decision of the mother separate analyses are performed for married mothers and single mothers the structural estimates are used to simulate the effects and costs of changes in the federal child care tax credit the simulations indicate that a refundable child care tax credit would distribute child care benefits more equally across the population by increasing the shares of subsidies received by low income families and would induce a considerable increase in expenditures on market child care labor supply also increases but by considerably less than child care expenditures a surprising result is that despite large increases in child care

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

household childcare choices and women s work behavior in russia the author models mothers participation in the labor force their working hours and household demand for childcare in russia the model estimates the effects of the price of childcare mothers wages and household income on household behavior and well being the theoretical model yields several predictions to test these reduced form equations of the discrete and continuous household choices are estimated jointly using the method of semi parametric full information maximum likelihood this method controls for the correlation of error terms across outcomes and the correlation of error terms that can result when panel data are used the results of this analysis indicate that the extent to which mothers participate in the labor force and for how many hours depends on the costs of childcare and on what level of hourly wage is available to them and to other members of the household the author s simulations show that family allowances intended to reduce poverty do not significantly affect the household choice of childcare arrangements replacing family allowances with childcare subsidies might have a strong positive effect on women s participation in the labor force and thus could be effective in reducing poverty
