quality adjusted cost functions and policy evaluation in the nursing home industry proper evaluation of cost quality trade offs inherent in regulatory policy requires identifying the structure of production from the behavioral response of quality to the policy change however estimating the structure of production with endogenous quality is difficult because of both measurement problems and data availability we develop a simple method for identifying and estimating cost functions in the presence of endogenous and unobserved quality using this method we estimate that a quality adjusted cost function for nursing homes treating quality as exogenous yields seriously misleading estimates of marginal cost and economies of scale we then used the parameter estimates to evaluate the cost quality trade off in nursing home regulatory policy

the credibility of policy announcements greek evidence this paper by using error correction ec methodology along with chow stability tests examines whether three cases of policy announcements in greece over the 1975 1995 period have been considered credible or not by the public focusing on the phillips curve trade off the empirical findings reveal that two out of three policy announcements are characterized as credible by private agents

how should control theory be used to calculate a time consistent government policy we study different solutions to a simple one dimensional linear quadratic game with a large number of private agents and a government a time consistent solution is defined as a solution to the hamilton jacobi bellman equation i e as a policy for which the government has noprecommitment capability this solution is compared to a policy where the government has an instantaneous pre commitment i e an equilibrium in which the government has a period by period leadership in both cases we show how control theory should be applied to calculate the equilibrium and how to relate these equilibria to the differential game literature

modelling the causes and manifestation of bank stress an example from the financial crisis in this study i model the predictors and manifestation of bank stress during the financial crisis using a multiple indicator multiple cause model unlike most early warning models that predict failure probabilities this article describes a framework for predicting a broader notion of bank stress that need not rely on regulatory decisions as such this method can be easily applied to large institutions and avoids the complications associated with modelling a regulatory decision such as failure or a camels downgrade using bank reliance on term auction facility funds and the out of sample incidence of failures and acquisitions i demonstrate that the measure of bank stress generated here accords with other notions of bank level distress finally this method catalogues predictors of distress during the financial crisis thus this article can help assess the validity of several recent regulatory proposals i find that those banks entering the crisis with more tier 1 capital more liquid balance sheets

inflation and reputation in many macroeconomic models with rational expectations optimal policy is time inconsistent and therefore announced policy may not be credible this paper models the government s credibility explicitly using kreps and wilson s analysis time consistent optimal government policy emerges as a sequential equilibrium in a repeated game this policy is at least as good as the inconsistent optimal policy and dominates the consistent policy when reputational effects are ignored thus the analysis resolves the problem of specifying a credible optimal policy in such models the results show why attempts to disinflate may lead to recession even with perfectly flexible prices this abstract was borrowed from another version of this item

the role of market forces in assuring contractual performance the conditions under which transactors can use the market repeat purchase mechanism of contract enforcement are examined increased price is shown to be a means of assuring contractual performance a necessary and sufficient condition for performance is the existence of price sufficiently above salvageable production costs so that the nonperforming firm loses a discounted steam of rents on future sales which is greater than the wealth increase from nonperformance this will generally imply a market price greater than the perfectly competitive price and rationalize investments in firm specific assets advertising investments thereby become a positive indicator of likely performance

a latent structure approach to measuring reputation the present study provides estimates of reputation as a dynamic latent variable that is determined by price premiums and market data further it analyzes the effect of extrinsic factors on reputation specifically this study seeks to i quantify the reputation of washington apples over time ii study the dynamic nature of reputation and iii analyze the effect of the label washington apple the model adopted in this study is the dynamic multiple indicator multiple cause dymimic modeling approach which is a special case of the general latent variable modeling scheme called state space models both dymimic and hedonic approaches are applied to the data on washington apples and results from the two approaches are compared reputation plays an important role in assuring product quality in markets where consumers can only imperfectly judge the product quality until after consumption if reputation effects are absent in these types of markets there is an incentive for producers to reduce quality and take short run gains before buyers catch on in order to avoid such quality cutting products with good reputations will sell for premium prices shapiro 1983 showed theoretically that price premiums are necessary for producers to invest in quality and reputation there is an extensive theoretical literature on reputation but empirical studies are limited empirical studies on the impact of firm reputation on shareholder wealth or product demand include jarrell and peltzman 1985 borenstein and zimmerman 1988 and karpoff and lott 1993 caves and green 1996 showed that factors that may affect a firm s reputation influence the relationship between price and quality gorton 1996 analyzed how a bank s reputation for default affects the discount rate on its debt the measurement of the value of reputation to producers in terms of price premiums and how a reputation can be built up and destroyed are important issues that have not been empirically analyzed the current study provides estimates of reputation as a dynamic latent variable that is determined by price premiums and market data further it analyzes the effect of extrinsic factors on reputation steenkamp 1990 points out that consumers observe at the moment of purchase the intrinsic and extrinsic product quality cues but not the quality attributes intrinsic cues are characteristics of the product such as color freshness texture and flavor while extrinsic

credibility of policies versus credibility of policymakers standard models of policy credibility defined as the expectation that an announced policy will be carried out emphasize the preferences of the policymaker and the role of tough policies in signaling toughness and raising credibility whether a policy is carried out however will also reflect the state of the economy we present a model in which a policymaker maintains a fixed parity in good times but devalues if the unemployment rate gets too high our main conclusion is that if there is persistence in unemployment observing a tough policy in a given period may lower rather than raise the credibility of a no devaluation pledge in subsequent periods we test this implication on ems interest rates and find support for our hypothesis

the origins of intergenerational associations lessons from swedish adoption data we use unique swedish data with information on adopted children s biological and adoptive parents to estimate intergenerational mobility associations in earnings and education we argue that the impact from biological parents captures broad prebirth factors including genes and prenatal environment and the impact from adoptive parents represents broad postbirth factors such as childhood environment we find that both pre and postbirth factors contribute to intergenerational earnings and education transmissions and that prebirth factors are more important for mother s education and less important for father s income we also find some evidence for a positive interaction effect between postbirth environment and prebirth factors

interest rates expectations and the credibility of the bank of spain the purpose of the paper is to pinpoint the date of the change of monetary policy regime which occurred in spain during the year 1984 when it moved away from controlling monetary aggregates towards interest rate targeting the most likely date for the change is estimated and surprisingly there is evidence that agents learned about the new intermediate target quite rapidly a week after the change the term structure of interest rates showed how market agents attributed much more informational content to interest rate changes than they had previously two types of transitions are tried a one step and a gradual logistic swithing function

can reputation resolve the monetary policy credibility problem abstract this paper addresses three problems with reputational equilibria in the barro gordon monetary policy game the multiplicity of equilibria the coordination problem and a chisel prone credibility problem a chisel proof credibility condition ensures that in response to a small deviation from the low inflation rate by the central bank it never pays for the private sector to acquiesce if the private sector can coordinate then a low but nonzero inflation outcome can be supported as a subgameperfect and chisel proof credible noncooperative equilibrium for an atomistic private sector the result can still hold in a game between successive monetary administrations

twin picks disentangling the determinants of risk taking in household portfolios this paper investigates risk taking in the liquid portfolios held by a large panel of swedish twins we document that the portfolio share invested in risky assets is an increasing and concave function of financial wealth leading to different risk sensitivities across investors human capital which we estimate directly from individual labor income also affects risk taking positively while internal habit and expenditure commitments tend to reduce it our microfindings lend strong support to decreasing relative risk aversion and habit formation preferences furthermore heterogeneous risk sensitivities across investors help reconcile individual preferences with representative agent models

capital is back wealth income ratios in rich countries 1700 2010 how do aggregate wealth to income ratios evolve in the long run and why we address this question using 1970 2010 national balance sheets recently compiled in the top eight developed economies for the united states united kingdom germany and france we are able to extend our analysis as far back as 1700 we find in every country a gradual rise of wealth income ratios in recent decades from about 200 300 in 1970 to 400 600 in 2010 in effect today s ratios appear to be returning to the high values observed in europe in the eighteenth and nineteenth centuries 600 700 this can be explained by a long run asset price recovery itself driven by changes in capital policies since the world wars and by the slowdown of productivity and population growth in line with the s g harrod domar solow formula that is for a given net saving

rational expectations and policy credibility following a change in regime we examine the dynamic path of an economy after a change in regime when neither the policy to be followed nor the reactions of the public are known the model is an application of kreps and wilson s reputation model to barro and gordon s macroeconomic policy game equilibrium is defined to be the dynamically consistent solution to a game between the government and the private sector it involves mixed strategies and bayesian learning by both sides until the uncertainty about government and public behaviour is resolved the absence of complete credibility of government policy and intransigence of private sector wage demands increase the output loss of disinflation the analysis also sheds light on the strategic nature of economic policymaking and the role of information in macroeconomics

the role of expectations in stabilization policy abstract this paper develops and tests a theory of the process by which private agents in an economy form expectations about government policy agents form and update their beliefs about the true state of government policy in a bayesian fashion the credibility of a policy is defined to be the subjective probability that the government is pursuing a reform policy rule the credibility of a reform of monetary or exchange rate policies is a function of the parameters of both monetary and fiscal policies the theory is applied to the chilean and argentine exchange reforms of the late 1970 s

a latent variable model of consumer taste determination and taste change for complex carbohydrates despite evidence that aggregate consumption of complex carbohydrates has risen over the last decade food consumption surveys suggest that fewer households are consuming less bread pasta rice potatoes and corn this paper estimates systems of complex carbohydrae demand using cross sectional data from 1977 78 and 1987 88 in order to explain this paradox changes in demand that are not explained by changes in prices or income are explained by variations in taste because tastes cannot be directly observed the paper uses a multiple indicator and multiple cause mimic model to construct a suitable proxy variable in the mimic approach the indicators are residuals from a household demand function that includes prices and incomes as explanatory variables while household and demograhic proxies are cause variables the objectives in applying the mimic model are to determine the effect of consumer tastes on complex carbohydrate demand and comparing cross sectional survey data from two different periods

a theory of ambiguity credibility and inflation under discretion and asymmetric information this paper develops a positive theory of credibility ambiguity and inflation under discretion and asymmetric information the monetary policymaker maximizes his own politically motivated objective function that is positively related to economic stimulation through monetary surprises and negatively related to monetary growth the relative importance he assigns to each target shifts stochastically through time his current preference trade off is known to him but not to the public when choosing the state contingent path of money growth for the present and the future the policymaker compares the benefits from current stimulation with the costs associated with higher future inflation expectations current monetary growth conveys information to the public about future money growth because there is persistence in the policymaker s objectives although expectations are rational information is imperfect because monetary control procedures are imprecise as a result the public cannot correctly distinguish persistent changes of emphasis on different policy objectives from transitory monetary control errors the public becomes aware of changes gradually by observing past monetary growth credibility is defined in terms of the speed with which the public recognizes changes in the objectives of the policymaker credibility is lower the noisier monetary control and the more stable the objectives of the policymaker looser monetary control and a higher degree of time preference on the part of the policymaker induce him to produce higher and more variable monetary growth when the policymaker is free to determine the accuracy of monetary control he does not always choose the most effective control available in spite of the fact that monetary surprises always have an expected value of zero the reason is that ambiguous control procedures enable the policymaker to generate positive surprises when he cares more than on average about economic stimulation he leaves the inevitable negative surprises for periods in which he cares more about inflation prevention this result provides an explanation for the fed s preference for ambiguity recently documented by goodfriend 1986 the policymaker is more likely to pick more ambiguous control procedures the more uncertain his objectives and the higher his time preference the paper also provides a theoretical underpinning for the well documented crosscountry positive correlation between the level and the variability of inflation

biases in standard measures of intergenerational income dependence abstract estimates of the most common mobility measure the intergenerational elasticity can be severely biased if snapshots are used to approximate lifetime income however little is known about biases in other popular dependence measures using long swedish income series we provide such evidence for log linear and rank correlations and rank based transition probabilities attenuation bias is considerably weaker in rank based measures life cycle bias is strongest in the elasticity moderate in log linear correlations and small in rank based measures however there are important exceptions persistence in the tails of the distribution is considerably higher and long distance downward mobility lower than estimates from short run income suggest

a latent variable model of quality determination because of data difficulties there has been little empirical work analyzing the determination of the quality of a firm s output this article constructs a latent variable model for this problem that uses easily obtainable data the model is developed from the relationship between the firm s input demand functions and reduced form output functions and it has a novel multiple indicator multiple cause mimic interpretation the model also allows identification of an intercept implying that an index of quality that is comparable across samples can be constructed as an example a latent variable model of nursing home quality is estimated

from the cradle to the labor market the effect of birth weight on adult outcomes lower birth weight babies have worse outcomes both short run in terms of one year mortality rates and longer run in terms of educational attainment and earnings however recent research has called into question whether birth weight itself is important or whether it simply reflects other hard to measure characteristics by applying within twin techniques using an unusually rich dataset from norway we examine the effects of birth weight on both short run and long run outcomes for the same cohorts we find that birth weight does matter despite short run twin fixed effects estimates that are much smaller than ols estimates the effects on longer run outcomes such as adult height iq earnings and education are significant and similar in magnitude to ols estimates

on the origins of risk taking in financial markets risk taking in financial markets is highly correlated between parents and their children however little is known about the extent to which these relationships are genetic or determined by environmental factors we use data on stock market participation of swedish adoptees and relate this to the investment behavior of both their biological and adoptive parents we find that stock market participation of parents increases that of children by about 34 and that both pre birth and post birth factors are important however once we condition on having positive financial wealth we find that nurture has a much stronger influence on risk taking by children and the evidence of a relationship between stock holding of biological parents and their adoptive children becomes weaker we find similar results when we study the share of financial wealth that is invested in stocks this suggests that a substantial proportion of the transmission of risk behavior from parents to children is environmentally determined

genetic variation in financial decision making individuals differ in how they construct their investment portfolios yet empirical models of portfolio risk typically account only for a small portion of the cross sectional variance this paper asks whether genetic variation can explain some of these individual differences following a major pension reform swedish adults had to form a portfolio from a large menu of funds we match data on these investment decisions with the swedish twin registry and find that approximately 25 of individual variation in portfolio risk is due to genetic variation we also find that these results extend to several other aspects of financial decision making

poor little rich kids the role of nature versus nurture in wealth and other economic outcomes and behaviors wealth is highly correlated between parents and their children however little is known about the extent to which these relationships are genetic or determined by environmental factors we use administrative data on the net wealth of a large sample of swedish adoptees merged with similar information for their biological and adoptive parents comparing the relationship between the wealth of adopted and biological parents and that of the adopted child we find that even prior to any inheritance there is a substantial role for environment and a much smaller role for pre birth factors and we find little evidence that nature nurture interactions are important when bequests are taken into account the role of adoptive parental wealth becomes much stronger our findings suggest that wealth transmission is not primarily because children from wealthier families are inherently more talented or more able but that even in relatively egalitarian sweden wealth begets wealth we further build on the existing literature by providing a more comprehensive view of the role of nature and nurture on intergenerational mobility looking at a wide range of different outcomes using a common sample and method we find that environmental influences are relatively more important for wealth related variables such as savings and investment decisions than for human capital we conclude by studying consumption as an overall measure of welfare and find that like wealth it is more determined by environment than by biology

policy credibility and inflation in a wage setting game this paper combines the conventional monetary policy game with a wage setting game among several non cooperating wage setters each with some monopoly power the inflationary bias in market economies is explained in terms of the wage competition bias this bias does not disappear even when the central bank communicates its policy goals precisely and credibly in a policy game with several non cooperative monopolistic wage setters and a central bank if discretionary policy is interpreted as wage setters being stackelberg leaders relative to the central bank a discretionary policy leads to both higher inflation and lower output

the swedish experience with pension reform sweden is one of few countries in europe to have introduced a comprehensive pension reform in 1998 sweden passed legislation that transformed its public pension system to a notional defined contribution ndc plan that is a defined contribution plan financed on a pay as you go basis in addition a second tier of funded individual accounts was introduced the reform had broad political support with more than 80 per cent of the votes in parliament this paper discusses the trends in retirement in sweden and assesses the experience with pension reform the objective was to design a fiscally sustainable system tied to economic growth with a clear link between contributions and benefits we discuss the challenges in meeting this goal the extent to which the swedish reform has succeeded and how the system affects beneficiaries the paper evaluates the experience of the individual funded accounts to date and concludes with an outlook for the future copyright 2006 oxford university press

measurement of industry conduct with a latent structure empirical industrial organization economists have long been concerned with measuring the degree of competition in markets and understanding its underlying determinants but they have faced serious difficulties including data requirements and misspecification issues this paper offers an alternative method of estimating market power and industry conduct market power is estimated for the fresh apple industry with a latent modelling structure specifically variations of the mimic model are adapted to this problem these variations are the multiple indicators mi and the filtered measure fm approaches the results suggest that although the washington apple industry has a large market share it does not exercise market power factors that mitigate the exertion of market power in the fresh apple market include competitor shipments and retailer power copyright 2004 john wiley sons ltd

is there a peso problem evidence from the dollar pound exchange rate 1976 1987 one of the most puzzling aspects of the floating exchange rate regime since 1973 has been the apparent irrationality embedded in investors exchange rate expectations this paper investigates whether exchange rate forecasts although biased are still rational the idea is that investors can be rational and yet make repeated mistakes if the true model of the exchange rate is evolving over time the author s results support the hypothesis that the exchange rate has followed a switching regime process moreover the switching regime model estimated can explain about 75 percent of the bias implied by the forward market and the survey data copyright 1993 by american economic association

ambiguous changes in product quality economic goods are frequently sold according to a price per unit quantity where the quantity characteristic does not measure all the economically important characteristics of the good milk is sold by the quart automobiles rented by the mile physicians services bought by the visit and tennis lessons by the hour in all cases heterogeneous units are available in the market and the price per unit quantity depends upon the amount of the unpriced characteristic contained in each unit the per quart price of milk depends upon the butterfat content the mileage costs of automobile rentals on the cars make and the price per unit time for personal services on the providers skill and training the common distinction made between these variants of the same good is that they differ in quality where quality refers to the amounts of the unpriced attributes contained in each unit of the priced attribute thus milk is packaged according to the attribute milk liquid and the quality of milk refers to the ratio of butterfat per unit of liquid 2 this paper considers some of the unique aspects of the economics of supply and demand under this situation where products contain at least two desired attributes only one of which is quantified and measured prior to purchase product quality is here defined by the ratio of the second quality attribute per unit of the measured quantity attribute 3 this simple specification of quality allows a direct link between standard economic models of related products and the economics of variable product quality previous analyses which treat quality simply as a shift parameter in the demand function are shown to obscure the actual subtleties of supply and demand with variable endogenous quality 4 the paper proceeds by first examining the efficient quality and quantity and the competitive equilibrium the market equilibrium under monopoly is then contrasted in the second section the general theme of the

credibility and changes in policy regime this paper addresses the issue of credibility from an econometric perspective it develops a rational expectations model of inflation in which the dynamics are driven by the level of government spending and by the effect of past inflation rates on the value of real taxes government expenditure is modeled as an exogenous autoregressive process subject to discrete changes in regime the regimes are defined by whether the level of spending is or is not consistent with the rate of inflation targeted by the government as part of a stabilization program in making their money demand decision the agents need to construct probability inferences regarding the state of the expenditure process credibility is quantified by the agents inferred probability that the joint observation of inflation the nominal interest rate and government spending is generated by the reformed expenditure regime in an application to israel results indicate that the failed stabilization program of november 1984 was less than fully c

sterling s erm credibility abstract this paper examines the recent credibility of the currencies participating in the erm since 1987 focusing on sterling in 1992 it shows that there is little market evidence that sterling s credibility was in serious doubt until mid september 1992

intergenerational wealth mobility in england 1858 2012 surnames and social mobility this article uses a panel of 18 869 people with rare surnames whose wealth is observed at death in england and wales 1858 2012 to measure the intergenerational elasticity of wealth over five generations we show using rare surnames to track families that wealth is much more persistent than standard one generation estimates would suggest there is still a significant correlation between the wealth of families five generations apart we show that this finding can be reconciled with standard estimates of wealth mobility by positing an underlying first order markov process of wealth inheritance with an intergenerational elasticity of 0 70 0 75 throughout the years 1858 2012

credibility disinflation and gradualism abstract the following conundrum is examined success or failure of a disinflation policy depends largely on expectations of maintained lower money growth this suggests two equilibria a a policy is expected to be maintained and succeeds policy makers are re elected maintaining the policy and validating initial expectations b a policy is not expected to be maintained and fails policy makers are not re elected the policy is not maintained validating initial expectations

the effects of poor neonatal health on children s cognitive development we make use of a new data resource merged birth and school records for all children born in florida from 1992 to 2002 to study the relationship between birth weight and cognitive development using singletons as well as twin and sibling fixed effects models we find that the effects of early health on cognitive development are essentially constant through the school career that these effects are similar across a wide range of family backgrounds and that they are invariant to measures of school quality we conclude that the effects of early health on adult outcomes are therefore set very early

intergenerational wealth mobility and the role of inheritance evidence from multiple generations this study estimates intergenerational correlations in mid life wealth across three generations and a young fourth generation and examines how much of the parent child association that can be explained by inheritances using a swedish data set we find parent child rank correlations of 0 3 0 4 and grandparents grandchild rank correlations of 0 1 0 2 conditional on parents wealth grandparents wealth is weakly positively associated with grandchild s wealth and the parent child correlation is basically unchanged if we control for grandparents wealth bequests and gifts strikingly account for at least 50 per cent of the parent child wealth correlation while earnings and education are only able to explain 25 per cent

payment source and the cost of hospital care evidence from a multiproduct cost function with multiple payers abstract this study investigates the capacity of hospitals to vary the intensity of their services based on patients expected sources of payment while the concept of price discrimination by hospitals based on payer generosity cost shifting has been discussed extensively the notion that hospitals can adjust payer specific marginal costs to reflect differences in reimbursement policies has not been studied in depth to examine this issue this analysis employs a multiproduct cost function with hospital outputs defined as admissions by payment source controlling for the distribution and severity of illness casemix for each payer marginal costs of casemix adjusted discharges are obtained and compared for medicare medicaid private payers and a residual category that includes uncompensated care we find that indeed payer specific marginal costs generally reflect payer generosity

disinflation credibility and price inertia a danish exposition this paper analyses the disinflationary policy pursued in denmark since october 1982 focusing on the phillips curve trade off and the credibility of this disinflationary policy the overall conclusion confirms no significant indication of the disinflationary policy being credible

on the international harmonization of bank regulation this paper offers a three way typology of bank regulation and examines the question of international harmonization for each category for economic regulation the danger is that harmonization could support and preserve domestic protectionist regulatory regimes but it could instead be a beneficial guise for lowering protectionist barriers the latter efforts should be encouraged for prudential regulation national regulation should be adequate to handle the extra stresses of international banking harmonization efforts e g the basle accord may offer only modest help but the accord may offer indirect help by limiting national governments competitive efforts implicitly to subsidize their banks risk taking activities finally for information regulation national regulation appears to be adequate and international harmonization does not appear to be necessary copyright 1994 by oxford university press

intergenerational top income mobility in sweden capitalist dynasties in the land of equal opportunity this paper presents new evidence on intergenerational mobility at the top of the income and earnings distributions using a large dataset of matched father son pairs in sweden we find that intergenerational transmission is very strong at the top more so for income than for earnings at the extreme top top 0 1 income transmission is remarkable with an intergenerational elasticity of approximately 0 9 we also study potential transmission mechanisms and find that iq non cognitive skills and education of the sons are all unlikely channels in explaining the strong transmission within the top percentile increases in the income of the fathers if they are related at all are negatively associated with these variables wealth on the other hand has a significantly positive association our results suggest that sweden known for having relatively high intergenerational mobility in general is a society in which transmission remains strong at the very top of the distribution and wealth is the most likely channel

credibility and stabilization the paper deals with stabilization as a one shot problem to ask what credibility means in a world where programs will succeed with probability one a model is spelled out where the equilibrium program has some ex ante probability of failure the model draws attention to the factors that raise or lower the probability of success of a stabilization program and thus offers a positive theory of stabilization reputation that emerges as a central element in repeated games has no role in this model
