debt and financial expectations an individual and household level analysis in this article we show that optimistic financial expectations impact positively on both the quantity of debt and the growth in debt at the individual and household levels our theoretical model shows that this association is predicted under a variety of plausible scenarios in the empirical analysis we explore the determinants of debt and of growth in debt using british data we find convincing support for our theoretical priors and show that it is optimistic financial expectations per se that are important in influencing debt rather than the accuracy of individuals predictions regarding their future financial situation jel d18 d84 d91

technical note delegating pricing responsibility to the salesforce in this paper we use an agency theory framework to address the issue of delegating pricing responsibility to the salesperson in this analysis it is shown that delegating the pricing responsibility to the salesperson is as profitable as centralization when the salesperson and the sales manager have identical information about the selling environment but delegation may be more profitable when the saleperson s information is superior to that of the sales manager s it is also argued that this characteristic is typical of market conditions where we observe delegation of such responsibility in cases identified by weinberg weinberg c b 1975 an optimal commission plan for salesman s control over price management sci 21 8 april 937 943 and stephenson cron and frazier stephenson p r w l cron g frazier 1979 delegating pricing authority to the salesforce the effects on sales and profit performance j marketing43 april 21 28

borrowing constraints and credit demand in a developing economy summary this paper investigates the determinants of credit demand in the presence of borrowing constraints in a developing economy we model the determinants of observed debt for chilean households while accounting for selection bias and the endogeneity of their income and specific household assets using a novel chilean dataset we estimate the relationship between household characteristics and consumer and mortgage debt we find substantial differences in the nature of these relationships across the types of debt for example we find that the income elasticity for consumer debt is greater than 1 whereas for mortgage debt it is not the results suggest the increased availability of credit combined with the aging of the chilean population is likely to drastically change the distribution and level of chilean debt these findings are particularly relevant for other developing economies currently experiencing rapid income and debt growth copyright 2015 john wiley sons ltd

the hyperbolic consumption model calibration simulation and empirical evaluation ur preferences for the long run tend to conflict with our short run behavior when planning for the long run we intend to meet our deadlines exercise regularly and eat healthfully but in the short run we have little interest in revising manuscripts jogging on the stairmaster and skipping the chocolate souffleala mode delay of gratification is a nice long term goal but instant gratification is disconcertingly tempting this gap between long run intentions and short run actions is apparent across a wide range of behaviors including saving choices a 1997 survey found that 76 percent of respondents believe they should be saving more for retirement looking only at respondents who believed they were at an age where you should be seriously saving already the survey found that 55 percent reported being behind in their savings and only 6 percent reported being ahead farkas and johnson 1997 the report on the survey concluded t he gaps between people s atti tudes intentions and behavior are troubling and threaten increased insecurity and dissatisfaction for people when they retire americans are simply not doing what logic and their own reasoning suggests they should be doing a 1993 luntz webber merrill lynch survey found similar answers when baby boomers were asked what percentage of your annual household income do you think you should save for retirement and what percentage of your annual

testing the response of consumption to income changes with noisy panel data this paper tests the rational expectations lifecycle model of consumption against i a keynesian model and ii the rational expectations lifecycle model with imperfect capital markets the tests are based upon the relative responsiveness of consumption to income changes that can be predicted from past information and income changes that cannot he predicted the tests allow for measurement error in income the results reject the keynesian model and generally support the lifecycle model but the results are not sufficiently precise to rule out the possibility that some households are liquidity constrained measurement error has a strong influence on the relationship between consumption and income

endogeneity in brand choice models applications of random utility models to scanner data have been widely presented in marketing for the last 20 years one particular problem with these applications is that they have ignored possible correlations between the independent variables in the deterministic component of utility price promotion etc and the stochastic component or error term in fact marketing mix variables such as price not only affect brand purchasing probabilities but are themselves endogenously set by marketing managers this work tests whether these endogeneity problems are important enough to warrant consideration when estimating random utility models with scanner panel data our results show that not accounting for endogeneity may result in a substantial bias in the parameter estimates

delegating pricing decisions in competitive markets with symmetric and asymmetric information delegating pricing decisions to the salesforce has been a salient issue for marketing academics and practitioners we examine this issue in a competitive market using standard agency theory with symmetric and asymmetric information under symmetric information we find that the optimal contracts have a nice property that allows managers to reach the upper bound on firms profit by using either centralized or delegated pricing and hence there are no incentive based reasons to prefer centralized versus delegated contract types thus managers can focus on the design of the optimal incentive scheme without worrying about the contract type under asymmetric information we find that there always exists an equilibrium where all firms use centralized pricing that is either unique or payoff equivalent to equilibria that have a combination of contract types these results are robust to a large class of agent and market parameters however if restrictions are exogenously imposed on contract form or observability the above results are no longer true as in earlier work we demonstrate our results by providing explicit solutions under the holmstrom and milgrom 1987 framework

constrained after college student loans and early career occupational choices abstract in the early 2000s a highly selective university introduced a no loans policy under which the loan component of financial aid awards was replaced with grants we use this natural experiment to identify the causal effect of student debt on employment outcomes in the standard life cycle model young people make optimal educational investment decisions if they are able to finance these investments by borrowing against future earnings the presence of debt has only income effects on investment decisions we find that debt causes graduates to choose substantially higher salary jobs and reduces the probability that students choose low paid public interest jobs we also find some evidence that debt affects students academic decisions during college our estimates suggest that recent college graduates are not life cycle agents two potential explanations are that young workers are credit constrained or that they are averse to holding debt we find suggestive evidence that debt reduces students donations to the institution in the years after they graduate and increases the likelihood that a graduate will default on a pledge made during her senior year we argue this result is more likely consistent with credit constraints than with debt aversion

two sided markets with pecuniary and participation externalities the existing literature on two sided markets addresses participation externalities but so far it has neglected pecuniary externalities between competing platforms in this paper we build a model that incorporates both externalities in our setup differentiated platforms compete in advertising and offer consumers a service free of charge such as a tv program that is financed through advertising we show that advertising can exhibit the properties of a strategic substitute or complement surprisingly there exist cases in which platforms benefit from market entry moreover we show that from a welfare point of view perfect competition is not always desirable

concentration and public policies in the broadcasting industry the future of television tv regulation concentration and public policies in the broadcasting industry new technologies are deeply transforming the broadcasting industry what we have seen so far is only the beginning of a long story inevitably industry regulations must adapt which means that a wide ranging rethink of current practices is required in order to assess the likely evolution of the industry this article decomposes it into a number of components from conception of programmes to their broadcasting including distribution storage and licensing contrary to popular expectations the analysis suggests that the current high degree of concentration will if anything increase the policy implication is that regulation so far driven by now obsolete technological constraints should increasingly emphasize promoting competition massimo motta and michele polo

platform competition in two sided markets many if not most markets with network externalities are two sided to succeed platforms in industries such as software portals and media payment systems and the internet must get both sides of the market on board accordingly platforms devote much attention to their business model that is to how they court each side while making money overall this paper builds a model of platform competition with two sided markets it unveils the determinants of price allocation and end user surplus for different governance structures profit maximizing platforms and not for profit joint undertakings and compares the outcomes with those under an integrated monopolist and a ramsey planner jel l5 l82 l86 l96

centralized pricing versus delegating pricing to the salesforce under information asymmetry the issue of delegating pricing responsibility to the salesforce is of interest to marketing academics and practitioners it has been shown by lal 1986 that under certain situations with information asymmetry it is more profitable for the firm to delegate pricing authority to the salesforce than to have centralized pricing in this paper we re examine situations where information asymmetry exists and analyze its effect on the decision of the firm to set a price or delegate pricing responsibility to the salesforce using contract theory we find that when the salesperson s private information can be revealed to the firm through contracting centralized pricing performs at least as well as price delegation we derive the optimal centralized pricing contract under a set of standard assumptions used in the economics and business literature

risk based pricing of interest rates for consumer loans abstract by focusing on observable default risk s role in loan terms and the subsequent consequences for household behavior this paper shows that lenders increasingly used risk based pricing of interest rates in consumer loan markets during the mid 1990s it tests three resulting predictions first the premium paid per unit of risk should have increased over this period second debt levels should have reacted accordingly third fewer high risk households should have been denied credit further contributing to the interest rate spread between the highest and lowest risk borrowers for people obtaining loans the premium paid per unit of risk did indeed become significantly larger after the mid 1990s for example for a 0 01 increase in the probability of bankruptcy the corresponding interest rate increase tripled for first mortgages doubled for automobile loans and rose nearly six fold for second mortgages additionally changes in borrowing levels and debt access reflected these new pricing practices particularly for secured debt borrowing increased most for the low risk households who saw their relative borrowing costs fall furthermore while very high risk households gained expanded access to credit the increases in their risk premiums implied that their borrowing as a whole either rose less or sometimes fell

contract complexity and performance under asymmetric demand information an experimental evaluation exploring the tension between theory and practice regarding complexity and performance in contract design is especially relevant the goal of this paper is to understand why simpler contracts may commonly be preferred in practice despite being theoretically suboptimal we study a two tier supply chain with a single supplier and a single buyer to characterize the impact of contract complexity and asymmetric information on performance and to compare theoretical predictions to actual behavior in human subject experiments in the experiments the computerized buyer faces a newsvendor setting and has better information on end consumer demand than the human supplier the supplier offers either a quantity discount contract with two or three price blocks or a price only contract contracts that are commonplace in practice yet different in complexity results show that contrary to theoretical predictions quantity discounts do not necessarily increase the supplier s profits we also observe a more equitable distribution of profits between the supplier and the buyer than what theory predicts these observations can be described with three decision biases the probabilistic choice bias the reinforcement bias and the memory bias and can be modeled using the experience weighted attraction learning model our results demonstrate that simpler contracts such as a price only contract or a quantity discount contract with a low number of price blocks are sufficient for a supplier designing contracts under asymmetric demand information this paper was accepted by christian terwiesch operations and supply chain management

household saving micro theories and micro facts in this survey we review the recent theoretical and empirical literature on household saving and consumption the discussion is structured around a list of motives for saving and how well the standard theory captures these motives we show that almost all of the motives for saving that have been suggested in the informal saving literature can be captured in the standard optimizing model particular attention is given to recent work on the precautionary motive and its implications for saving and consumption behavior we also discuss the behavioral or psychological approach that eschews the use of standard optimization techniques and focuses instead on direct consideration on saving we provide a section on facts who save and how much we then discuss informally the recent decline in the u s saving rate and whether the theory is of much use in understanding this and other changes in aggregate saving rates over time we do not find any convincing explanation for the change in saving rates we also discuss some analyses of saving behavior over the life cycle addressing such questions as whether households save enough for retirement and whether the consumption patterns of older households can be rationalized within a simple life cycle model we also review a great number of studies of the consumption euler equations based on our analysis of the studies cited we conclude that there is still mixed evidence that consumption is excessively sensitive to income we also examine in depth the recent empirical literature on the precautionary motive we conclude that although some households do seem to have a significant precautionary motive at some points in their life cycle this motive is not so strong empirically as some investigators suggest

testing for liquidity constraints in euler equations with complementary data sources previous tests for liquidity constraints using consumption euler equations have frequently split the sample on the basis of wealth arguing that low wealth consumers are more likely to be constrained we propose alternative tests using different and more direct information on borrowing constraints obtained from the 1983 survey of consumer finances in a first stage we estimate probabilities of being constrained which are then utilized in a second sample the panel study of income dynamics to estimate switching regression models of the euler equation our estimates indicate stronger excess sensitivity associated with the possibility of liquidity constraints than the sample splitting approach

the pricing of revenue assurance reply in their comment yin and turvey yt suggest an approach to overcome a potential problem with stokes nayda and english s sne s methodology for valuing revenue insurance the problem as discussed in sne and yt is that farm gross revenue is not a traded asset therefore revenue insurance which is itself a derivative security i e a security that derives its value from the value of another asset in this case farm gross revenue is difficult to price using standard asset pricing methods because buying and selling the underlying asset to hedge away risk is not possible sne assume an equilibrium pricing function exists and and in doing so are left with one unobservable parameter in their pricing formula yt s comment is essentially to propose a method for eliminating this unknown parameter the problem is that an underlying asset for which a derivative security is written against is not tradable the importance of tackling this issue cannot be over emphasized and yt are to be commended for their efforts indeed virtually no other research besides sne and yt approaches the problem of premium determination for agricultural insurance from the perspective of treating the insurance as a derivative security 1 the importance of doing so is that one gains access to contemporary asset pricing methodology in this reply we focus on two important issues related to the problems created by nontradability first we clarify the tradable versus nontradable distinction in terms of its implications for arbitrage free pricing the results we present provide the necessary background for motivating yt s equation 1 whereas yt begin their comment by assuming an economy that justifies their equation 1 we provide a mathematical characterization of the economy that insures the equation holds taking this approach gives us the opportunity to define the issues yt raise more clearly because the mathj r stokes is assistant professor at the pennsylvania state university university park pa w i nayda is manager of financial analysis and development at capital one inc mclean va 1 counter examples include research by turvey and amanor

market provision of broadcasting a welfare analysis this paper presents a theory of the market provision of broadcasting and uses it to address the nature of market failure in the industry advertising levels may be too low or too high depending on the nuisance cost to viewers the substitutability of programs and the expected benefits to advertisers from contacting viewers market provision may allocate too few or too many resources to programming and these resources may be used to produce programs of the wrong type monopoly ownership may produce higher social surplus than competitive ownership and the ability to price programming may reduce social surplus

credit card debt and default over the life cycle this paper solves an empirically parameterized model of life cycle consumption which allows for uncollaterized borrowing and the possibility of default the simulation results show that i social stigma and credit limit have a very large impact on default rates ii education level also has a significant effect on the probability of default namely through differences in the shape of lifetime labor income profiles and iii the response of simulated default rates to labor income shocks is determined by the nature of labor income uncertainty temporary versus permanent additionally the model generates simultaneous consumer holdings of credit card debt and liquid assets

do consumers need more protection from small dollar lenders historical evidence and a roadmap for future research we summarize the current debate surrounding four small dollar credit products pawn loans vehicle title loans payday loans and cash installment loans from finance companies we review the contributions of scholars that inform this debate we underscore that users of these products fit the description of those whom consumer credit models predict benefit from these products many studies find that on average consumer use of small dollar credit products is at worst innocuous there are however findings of heterogeneity in borrowers experiences the disagreements surrounding these credit products and the difficulty in crafting the proper policy response stems from this heterogeneity jel d18 g23

a portfolio view of consumer credit abstract to compute risk adjusted returns and gauge the volatility of their portfolios lenders need to know the covariances of their loans returns with aggregate returns we use unique credit bureau data to measure individuals covariance risk i e the covariance of their default risk with aggregate consumer default rates and more generally to analyze the distribution of credit including the effects of credit scores we find significant heterogeneity in covariance risk across consumers also the amount of credit they obtain significantly increases with their credit scores and decreases with their covariance risk especially revolving credit though the effect of covariance risk is smaller

how effective are rewards programs in promoting payment card usage empirical evidence card issuers have mainly relied on rewards programs as their main strategy to increase usage however there is scarce evidence on the effectiveness of these programs this paper is addressing two topics which could have important managerial and public policy implications i it estimates the impact of rewards on the use of cards and ii it quantifies their economic effects in terms of the cash substitution we find that rewards may significantly modify choice for card payments their economic impact also varies significantly across types of rewards and merchant activities additionally rewards seem to be more effective for debit cards

reading the fine print information disclosure in the brazilian credit card market consumer credit regulations usually require that lenders disclose interest rates however in the absence of specific prominence requirements lenders can conceal the interest rate in the fine print while still complying with the law i examine the effect of such a strategy using a field experiment in brazil in which a credit card company offered their clients payment plans to pay off their balances using randomized contract interest rates and the degree of rate disclosure i show that most clients are rate sensitive whether or not rates are prominently disclosed the elasticity of payment plan enrollment with respect to the interest rate ranges from 0 711 to 0 880 high risk clients are an exception these clients are rate sensitive only when disclosure is prominent i also show that clients are influenced by nudges that favor longer term contracts conditional on enrollment the proportion of clients who choose a longer term contract is 40 percentage points higher when a longer term contract is feat

estimating interest rate elasticities in consumer credit based on a unique dataset with monthly loan account data for three types of consumer credit i estimate the interest rate elasticity of the demand for credit across credit types the main result shows that elasticities vary depending on the credit type used in the estimation moreover borrower heterogeneity with respect to interest rate elasticities differs across credit types too these results have important implications for policy measures aimed at stimulating borrowing and consumption

chicken and egg competition among intermediation service providers we analyze a model of imperfect price competition between intermediation service providers we insist on features that are relevant for informational intermediation via the internet the presence of indirect network externalities the possibility of using the nonexclusive services of several intermediaries and the widespread practice of price discrimination based on users identity and on usage efficient market structures emerge in equilibrium as well as some specific form of inefficient structures intermediaries have incentives to propose non exclusive services as this moderates competition and allows them to exert market power we analyze in detail the pricing and business strategies followed by intermediation services providers copyright 2003 by the rand corporation

an intertemporal general equilibrium model of asset prices this paper develops a continuous time general equilibrium model of a simple but complete economy and uses it to examine the behavior of asset prices in this model asset prices and their stochastic properties are determined endogenously one principal result is a partial differential equation which asset prices must satisfy the solution of this equation gives the equilibrium price of any asset in terms of the underlying real variables in the economy in this paper we develop a general equilibrium asset pricing model for use in applied research an important feature of the model is its integration of real and financial markets among other things the model endogenously determines the stochastic process followed by the equilibrium price of any financial asset and shows how this process depends on the underlying real variables the model is fully consistent with rational expectations and maximizing behavior on the part of all agents our framework is general enough to include many of the fundamental forces affecting asset markets yet it is tractable enough to be specialized easily to produce specific testable results furthermore the model can be extended in a number of straightforward ways consequently it is well suited to a wide variety of applications for example in a companion paper cox ingersoll and ross 7 we use the model to develop a theory of the term structure of interest rates many studies have been concerned with various aspects of asset pricing under uncertainty the most relevant to our work are the important papers on intertemporal asset pricing by merton 19 and lucas 16 working in a continuous time framework merton derives a relationship among the equilibrium expected rates of return on assets he shows that when investment opportunities are changing randomly over time this relationship will include effects which have no analogue in a static one period model lucas considers an economy with homogeneous individuals and a single consumption good which is produced by a number of processes the random output of these processes is exogenously determined and perishable assets are defined as claims to all or a part of the output of a process and the equilibrium determines the asset prices our theory draws on some elements of both of these papers like merton we formulate our model in continuous time and make full use of the analytical tractability that this affords the economic structure of our model is somewhat similar to that of lucas however we include both endogenous production and

social security and unsecured debt abstract in this paper we use a calibrated life cycle model to explore quantitatively ways of reducing the burden of social security in a world populated by both optimizing and rule of thumb consumers social security contributions force young households with upward sloping income profiles to save a sizeable portion of their income for retirement when their optimal consumption plan would likely have them either saving little or borrowing we first use household data to document that young households have accumulated social security contributions that are large relative to debt holdings then using a calibrated life cycle model we show that both allowing households to use social security wealth to pay off their debt and exempting young households from social security contributions but in both cases requiring higher contributions later mitigate many of the inefficiencies of social security from the perspective of life cycle financial planning specifically in our preferred experiment which exempts households whose heads are under 30 from making social security contributions we find that certainty equivalent consumption increases by 3 4 for optimizing households and by 3 3 for rule of thumb households

subprime consumer credit demand evidence from a lender s pricing experiment using a unique panel data set from a u k credit card company we analyze the interest rate sensitivity of subprime credit card borrowers in addition to all individual transactions and loan terms we have access to details of a randomized interest rate experiment conducted by the lender on existing inframarginal loans for the whole sample we estimate a statistically significant 3 4 reduction in monthly credit demand in response to a five percentage point increase in interest rates this aggregate response is small but it masks very interesting heterogeneity in the sample we find that only low risk borrowers who fully utilize their credit cards lower their credit demand significantly when faced with an increase in interest rates we also document that a five percentage point increase in interest rates generates significant additional revenue for the lender without inducing delinquency over a short horizon 2013 the author

the reaction of household consumption to predictable changes in social security taxes the key implication of rational expectations and the basic life cycle permanent income hypothesis that predictable changes in income have no effect on the growth rate of consumption expenditures is examined this implication is important for understanding the effectiveness and optimal timing of fiscal policy the causes and propagation of business cycles and the effects of income fluctuations on the growth rate of the economy using household level consumption data from the consumer expenditure survey whether expenditures on nondurable goods increase contemporaneously with predictable changes in social security tax withholding is tested it is found that households do change their consumption expenditures in response to the predictable fluctuations in income induced by the social security tax system

press advertising and the ascent of the pensee unique the press industry depends in a crucial way on the possibility of financing an important fraction of its activities by advertising receipts we show that this induces the editors of newspapers to moderate in several cases the political message they display to their readers compared with the political opinions they would have expressed otherwise to this end we consider a three stage game in which editors select sequentially their political image the price of their newspaper and the advertising tariff they oppose to the advertisers the intuition of the result lies in the fact that editors have to sell tasteless political messages to their readers in order to sell a larger audience to the advertisers

precommitments for financial self control micro evidence from the 2003 korean credit crisis we analyze high frequency micro panel data on customers of a major korean credit card company before and after the 2003 korean credit crisis and find evidence of pervasive precommitment behavior that is difficult to explain using standard economic theories 1 customers voluntarily reduce their credit card borrowing limits without any compensation 2 customers turn down interest free installment loan offers with high probability and 3 of the small fraction of customers who do accept interest free loan offers most precommit to pay off the loan over a shorter term than the maximum allowed term under the offer

who is credit constrained in the u s economy an important assumption of the life cycle model of consumption is the postulate of perfect capital markets this hypothesis has recently been challenged by substantial empirical evidence hall and mishkin 1982 using the panel study of income dynamics estimate that 20 percent of united states families are liquidity constrained mariger 1986 derives a life cycle model with endogenous liquidity constraints and using a cross section estimates this fraction to be 19 4 percent hubbard and judd 1986 simulate a model with a constraint on net worth which shows that with reasonable assumptions about preferences 19 0 percent of united states consumers are liquidity constrained the emerging consensus points therefore to a fraction of approximately 20 percent of the population behaving in a manner that is inconsistent with the pure life cycle model in addition hayashi 1985 and zeldes 1989 investigate the correlation among consumption wealth and income for various population groups and infer that liquidity constraints are more important for younger families with low levels of wealth and saving the main limitation of these studies is that in their data sets constrained consumers are not observable and have to be identified via indirect evidence thus there is as yet little firm evidence about the characteristics of the consumers who are likely to be credit constrained this paper adopts an approach that differs from previous tests for liquidity constraints because it makes use of data where constrained consumers are observable and explicitly links their existence to credit market imperfections and personal characteristics the data drawn from the 1983 survey of consumer finances scf and described in section ii provide information on individuals whose request for credit has been rejected by financial intermediaries in section iii a model is developed in which consumers and lenders behavior jointly determines the probability that a consumer is rationed in the credit market this probability is then

saving and liquidity constraints this paper is concerned with the theory of saving when consumers are not permitted to borrow and with the ability of such a theory to account for some of the stylized facts of saving behavior the models presented in the paper seem to account for important aspects of reality that are not explained by traditional life cycle models copyright 1991 by the econometric society

the persistence of financial distress using recently available proprietary panel data we show that while many 35 us consumers experience financial distress at some point in the life cycle most of the events of financial distress are primarily concentrated in a much smaller proportion of consumers in persistent trouble roughly 10 of consumers are distressed for more than a quarter of the life cycle and less than 10 of borrowers account for half of all distress events these facts can be largely accounted for in a straightforward extension of a workhorse model of defaultable debt that accommodates a simple form of heterogeneity in time preference but not otherwise

entrepreneurial finance credit cards and race this paper examines the impact of financial deregulation on entrepreneurship we assess the impact of credit card deregulation on transitions into self employment using state level removal of credit card interest rate ceilings following the us supreme court s 1978 marquette decision as a quasi natural experiment we find that credit card deregulation increases the probability of entrepreneurial entry with a particularly strong effect for black entrepreneurs we demonstrate that these effects are magnified in states with a history of racial discrimination and link the results to discriminationbased barriers to entry 2012 elsevier b v all rights reserved

a dual self model of impulse control we propose that a simple dual self model gives a unified explanation for several empirical regularities including the apparent time inconsistency that has motivated models of quasi hyperbolic discounting and rabin s paradox of risk aversion in the large and small the model also implies that self control costs imply excess delay as in the o donoghue and rabin models of quasi hyperbolic utility and it explains experimental evidence that increased cognitive load makes temptations harder to resist the base version of our model is consistent with the gul pesendorfer axioms but we argue that these axioms must be relaxed to account for the effect of cognitive load

consumer credit evidence from italian micro data in this paper we analyse unique data on credit applications received by the leading provider of consumer credit in italy findomestic the data set covers a five year period 1995 1999 during which the consumer credit market rapidly expanded in italy and a new law the usury law came into force that set a limit on interest rates charged to consumers we compute behavioural changes by controlling for changes in the observable characteristics of the findomestic clientele and argue that under suitable identifying assumptions these changes can be given a structural interpretation if the usury shock is assumed to have affected credit supply but not credit demand that is if the usury law had a differential impact on the supply of various types of credit but a uniform impact on demand then we can identify and estimate a demand equation our key finding is that demand is interest rate elastic particularly in the more affluent north 2005 by the european economic association

the sense and non sense of holdout sample validation in the presence of endogeneity market response models based on field generated data need to address potential endogeneity in the regressors to obtain consistent parameter estimates another requirement is that market response models predict well in a holdout sample with both requirements combined it may seem reasonable to subject an endogeneity corrected model to a holdout prediction task and this is quite common in the academic marketing literature one may be inclined to expect that the consistent parameter estimates obtained via instrumental variables iv estimation predict better than the biased ordinary least squares ols estimates this paper shows that this expectation is incorrect that is if the holdout sample is similar to the estimation sample so that the regressors are endogenous in both samples holdout sample validation favors regression estimates that are not corrected for endogeneity i e ols over estimates that are corrected for endogeneity i e iv estimation we also discuss ways in which holdout samples may be used sensibly in the presence of endogeneity a key takeaway is that if consistent parameter estimates are the primary model objective the model should be validated with an exogenous rather than endogenous holdout sample

the reaction of consumer spending and debt to tax rebates evidence from consumer credit data we use a new panel data set of credit card accounts to analyze how consumers responded to the 2001 federal income tax rebates we estimate the monthly response of credit card payments spending and debt exploiting the unique randomized timing of the rebate disbursement we find that on average consumers initially saved some of the rebate by increasing their credit card payments and thereby paying down debt but soon afterward their spending increased counter to the permanent income model spending rose most for consumers who were initially most likely to be liquidity constrained whereas debt declined most so saving rose most for unconstrained consumers

new empirical generalizations on the determinants of price elasticity abstract the importance of pricing decisions for firms has fueled an extensive stream of research on price elasticities in an influential meta analytical study tellis 1988 summarized price elasticity research findings until 1986 however empirical generalizations on price elasticity require modifications because of 1 changes in market characteristics i e characteristics of brands product categories and economic conditions and 2 changes in the research methodology used to assess price elasticities therefore the authors present a meta analysis of price elasticity with new empirical generalizations on its determinants across a set of 1851 price elasticities based on 81 studies the average price elasticity is 2 62 a salient finding is that over the past four decades sales elasticities have significantly increased in magnitude whereas share and choice elasticities have remained fairly constant the authors find that accommodating price endogeneity has a strong magnitude increasing impa

credit elasticities in less developed economies implications for microfinance policymakers often prescribe that microfinance institutions increase interest rates to eliminate their reliance on subsidies this strategy makes sense if the poor are rate insensitive then microlenders increase profitability or achieve sustainability without reducing the poor s access to credit we test the assumption of price inelastic demand using randomized trials conducted by a consumer lender in south africa the demand curves are downward sloping and steeper for price increases relative to the lender s standard rates we also find that loan size is far more responsive to changes in loan maturity than to changes in interest rates which is consistent with binding liquidity constraints

which early withdrawal penalty attracts the most deposits to a commitment savings account previous research has shown that some people voluntarily use commitment contracts that restrict their own choice sets we study how people divide money between two accounts a liquid account that permits unrestricted withdrawals and a commitment account that is randomly assigned in a between subject design to have either a 10 early withdrawal penalty or a 20 early withdrawal penalty or not to allow early withdrawals at all i e an infinite penalty when the liquid account and the commitment account pay the same interest rate higher early withdrawal penalties attract more commitment account deposits this pattern is predicted by the hypothesis that some participants are partially or fully sophisticated present biased agents such agents perceive that higher penalties generate greater scope for commitment by disincentivizing penalized early withdrawals the experiment also shows that when the commitment account pays a higher interest rate than the liquid account the positive empirical slope relating penalties and commitment deposits is flattened suggesting that naive present biased agents or agents with standard exponential discounting are also in our sample across all of our experimental treatments higher early withdrawal penalties on the commitment account sometimes increase and never reduce allocations to the commitment account

an empirical analysis of personal bankruptcy and delinquency this article uses a new dataset of credit card accounts to analyze credit card delinquency personal bankruptcy and the stability of credit risk models we estimate duration models for default and assess the relative importance of different variables in predicting default we investigate how the propensity to default has changed over time disentangling the two leading explanations for the recent increase in default rates a deterioration in the risk composition of borrowers versus an increase in borrowers willingness to default due to declines in default costs even after controlling for risk composition and economic fundamentals the propensity to default significantly increased between 1995 and 1997 standard default models missed an important time varying default factor consistent with a decline in default costs debt issued by consumers is an understudied asset class there has been particularly little academic study of recent trends in default on this debt between 1994 and 1997 the number of personal bankruptcy filings in the united states rose by about 75 the 1 35 million filings in 1997 represented well over 1 of u s households delinquency rates on credit cards rose almost as sharply federal reserve bank of cleveland 1998 the resulting losses to lenders amounted to a sizable fraction of the interest payments they collect potentially raising the average cost of credit these trends in default both in bankruptcy and delinquency are especially surprising in light of the strong economy over the period they provide an unusually rich source of variation to test the stability of models that forecast personal default and of credit risk models more generally there are two leading explanations for these trends first the risk composition of borrowers might have worsened under the risk effect less

option pricing when the underlying asset earns a below equilibrium rate of return a note in their classic paper black and scholes 2 present two derivations of the european call option pricing formula the first which we will refer to as the replication derivation relies on the fact that the returns from the option can be replicated by holding a continuously revised position in the underlying asset and bonds this implies that if an option is not priced according to the blackscholes formula there is a sure profit to be made by some combination of either short or long sales of the option and underlying asset this argument is seemingly independent of considerations relating to capital market equilibrium the second derivation which we will call the equilibrium derivation evolves from the requirement that the option earn an expected rate of return commensurate with the risk involved in holding the option as an asset this note considers the pricing of a call option on an asset which earns an expected rate of return lower than that necessary to induce investors to hold it we show in this case that even if the replication strategy is feasible it is inefficient a consequence of this is that the correct option pricing formula is different than the black scholes formula unlike the black scholes formula our formula requires as an input the difference between the expected rate of return on the underlying asset and that expected rate of return which would be required to induce holding of the asset other papers have made a similar point constantinides 3 and cox et al 4 have argued that in equilibrium the prices of traded contingent claims must satisfy a partial differential equation which is identical to the black scholes partial differential equation only when the underlying asset pays no dividends and earns a rate of return sufficient to induce holding of the asset more recently ingersoll 5 has noted that commodities often pay a nonpecuniary service yield the value of which must be taken into account in deriving the option price none of these authors however explain why the black scholes formula is sometimes inappropriate the purpose of this note is to demonstrate why the black scholes formula needs modification even if replication is feasible we provide an intuitive derivation of the correct formula and discuss why divergences of the equilibrium price from the black scholes formula do not result in arbitrage opportunities

delegating pricing decisions an outstanding problem in marketing is why some firms in a competitive market delegate pricing decisions to agents and other firms do not this paper analyzes the impact of competition on the delegation decision and in turn the impact of delegation on prices and incentives the theory builds on the simplest framework of competition in two dimensions prices and sales agents effort specifically we are interested in answering the following questions 1 does competition affect the price delegation decision and if yes why 2 how do prices vary under price delegation and no price delegation scenarios 3 do the incentives to the sales representatives vary under the delegation and no delegation scenarios to address these issues we build a game theoretic model that consists of two firms selling through their sales representatives these representatives are company employees sales are a function of prices and selling efforts the risk neutral firms decide whether or not to delegate the pricing decision to risk averse sales representatives the wages to the sales representatives consist of salary plus a commission on gross margins the commission on gross margins can be adjusted either through communicated marginal cost of production which we call virtual marginal cost or directly the firm and the sales representative are assumed to have the same information about the market that is there is no information asymmetry with competition in two dimensions the strategic nature of decision variableprice depends on the relative intensity of competition with unobservable contracts and risk averse sales representatives firms delegate the pricing decision when price competition is intense part of the uncertainty in demand is absorbed by the firm by keeping virtual marginal cost greater than the marginal cost of production the competing firm infers this through the risk aversion of the sales representatives under price delegation the sales representatives wages are higher and they set a price that is higher than what the firms would have set themselves this leads to softening of price competition that is to the advantage of both firms when the effort competition is dominant however the firms prefer to make the pricing decision themselves because this reduces the intensity of effort competition among agents a single instrument commission structure in which the firms adjust the virtual marginal cost is compared to a two instrument commission structure in which the firms can adjust the commission rate as well the virtual marginal cost under no price delegation the two incentive schemes are the same however under price delegation the risk premium with the two instrument scheme is lower however the prices and efforts are higher with the single instrument scheme when price competition is intense the increase in risk premium with the single instrument scheme is more than compensated for by the increase in profits this is the benefit of softening price competition through higher prices

context dependent drivers of discretionary debt decisions explaining willingness to borrow for experiential purchases mental accounting research suggests that consumers prefer borrowing for longer lasting purchases in order to receive benefits from the purchases as they pay for them in contrast two sets of archival data and five lab studies show that consumers are more willing to borrow for experiential versus material purchases even though experiential purchases tend to have a shorter physical duration further framing the same purchase as more experiential than material increases willingness to borrow this effect occurs because purchase timing is more important for experiential purchases a function of consumers aversion to missing out on planned consumption thus we moderate the proposed effect by varying whether the borrowing decision impacts planned consumption other differences between material and experiential purchases such as scarcity or expected happiness cannot similarly explain our results moreover our conceptualization allows us to reconcile the apparent contradiction between the previous and current research by examining the relative impact of purchase timing importance and payment benefit duration matching in different contexts i e purchasing and source of funding decisions

do liquidity constraints and interest rates matter for consumer behavior evidence from credit card data this paper utilizes a unique new dataset of credit card accounts to analyze how people respond to changes in credit supply the data consist of a panel of thousands of individual credit card accounts from several different card issuers with associated credit bureau data we estimate both marginal propensities to consume mpcs out of liquidity and interest rate elasticities we also evaluate the ability of different models of consumption to rationalize our results distinguishing the permanent income hypothesis pih liquidity constraints precautionary saving and behavioral models we find that increases in credit limits generate an immediate and significant rise in debt counter to the pih the average mpc out of liquidity ddebt dlimit ranges between 10 14 the mpc is much larger for people starting near their limits consistent with binding liquidity constraints however the mpc is significant even for people starting well below their limit we show this response is consistent with buffer stock models of precautionary saving nonetheless there are other results that conventional models cannot easily explain e g why so many people are borrowing on their credit cards and simultaneously holding low yielding assets unlike most other studies we also find strong effects from changes in account specific interest rates the long run elasticity of debt to the interest rate is approximately 1 3 less than half of this elasticity represents balance shifting across cards with most reflecting net changes in total borrowing the elasticity is larger for decreases in interest rates than for increases which can explain the widespread use of temporary promotional rates the elasticity is smaller for people starting near their credit limits again consistent with liquidity constraints

valuing agricultural insurance this paper proposes a method for estimating a farmer s stochastic discount factor that is independent of his or her risk preferences and shows that that stochastic discount factor is appropriate for calculating a farmer s willingness to pay for a crop insurance product an empirical example illustrates how production and price data might be combined with returns data to permit econometric estimation of the stochastic discount factor and the implications of those illustrative results are briefly discussed

two sided markets a progress report the paper provides a road map to the burgeoning literature on two sided markets and presents new results it identifies two sided markets with markets in which the structure and not only the level of prices charged by platforms matters the failure of the coase theorem is necessary but not sufficient for two sidedness the paper builds a model integrating usage and membership externalities that unifies two hitherto disparate strands of the literature emphasizing either form of externality and obtains new results on the mix of membership and usage charges when price setting or bargaining determine payments between end users

fiscal policy with heterogeneous agents and incomplete markets i undertake a quantitative investigation into the short run effects of changes in the timing of proportional income taxes for model economies in which heterogeneous households face a borrowing constraint temporary tax changes are found to have large real effects in the benchmark model a temporary tax cut increases aggregate consumption on impact by around 29 cents for every dollar of tax revenue lost comparing the benchmark incomplete markets model to a complete markets economy income tax cuts provide a larger boost to consumption and a smaller investment stimulus when asset markets are incomplete copyright 2005 wiley blackwell

self control financial literacy the co holding puzzle we use uk survey data to analyze the puzzling co existence of high cost revolving consumer credit alongside low yield liquid savings in household balance sheets which we name the co holding puzzle approximately 12 of households in our sample co hold on average 3800 of revolving consumer credit on which they incur interest charges even though they could immediately pay down all this debt using their liquid assets co holders are typically more financially literate with above average income and education in most estimates co holding is also associated with impulsive spending behavior on the part of the household our results provide empirical support to theoretical models in which households co hold as a means of managing self control problems

interest rates and informational issues in the credit market experimental evidence from brazil summary this paper utilizes brazilian data to investigate interest rate sensitivity and informational issues associated with the credit demand of the middle income class in a large emerging economy this study s data were collected from an experiment in which credit offers with randomized interest rates were sent to recipients the results indicate that credit constraints and informational issues are important for both the lower middle class and higher middle class income groups interest rate reductions may be more effective for higher income groups

regulation and competition in the taiwanese pharmaceutical market under national health insurance this article investigates the determinants of the prices of pharmaceuticals and their impact on the demand for prescription drugs in the context of taiwan s pharmaceutical market where medical providers earn profit directly from prescribing and dispensing drugs based on product level data we find evidence that the profit seeking behavior of the medical providers in the prescription drug market transfers the force of competition from the unregulated wholesale market to the regulated retail market and hence market competition still plays an important role in the determination of the regulated price we also find that the profit seeking behavior plays a similar role to advertising in that it increases the brand loyalty and hence lowers price elasticity an important implication of our study is that the institutional features in the pharmaceutical market matter in shaping the nature of pharmaceutical competition and the responsiveness of pharmaceutical consumption with respect to changes in price

on the premium for revenue insurance under joint price and yield risk this note provides two results pertaining to the pricing of agricultural revenue insurance contracts under joint price and yield risk first a weakening of the concordance ordering is used to sign the effect of greater dependence between the multiplicative risks price and yield on the expected indemnity payment second sufficient conditions are found when the premium rate for revenue insurance is smaller greater than the premium for the corresponding single risk price or yield insurance

the impact of mortgage interest rate subsidies on household borrowing abstract the responsiveness of household borrowing to changes in the interest rate is a crucial parameter for assessing public policies aimed at promoting saving we estimate the effect on household borrowing of a reform of a program that subsidized interest rates on mortgages signed by medium and low income households the reform established a ceiling in the price of the house that could be financed with the program first we use triple difference estimators exploiting the fact that the reform should affect most the borrowing behavior of eligible individuals living in high price areas and estimate that the elasticity of the probability getting a loan to the interest rate lies between 2 8 and 1 3 second we document that after the reform the distribution of loan sizes became more concentrated at the discontinuity point of the budget constraint of eligible individuals both findings are consistent with a negative response of household borrowing to increases in interest rates

a control function approach to endogeneity in consumer choice models abstract endogeneity arises for numerous reasons in models of consumer choice it leads to inconsistency with standard estimation methods that maintain independence between the model s error and the included variables the authors describe a control function approach for handling endogeneity in choice models observed variables and economic theory are used to derive controls for the dependence between the endogenous variable and the demand error the theory points to the relationships that contain information on the unobserved demand factor such as the pricing equation and the advertising equation the authors approach is an alternative to berry levinsohn and pakes s 1995 product market controls for unobserved quality the authors apply both methods to examine households choices among television options including basic and premium cable packages in which unobserved attributes such as quality of programming are expected to be correlated with price without correcting for endogeneity aggregate d

the response of household consumption to income tax refunds a central implication of the life cycle or permanent income theory is that consumption should not respond to predictable fluctuations in income tests of this implication have yielded mixed results especially on micro data angus deaton 1992 martin browning and annamaria lusardi 1996 in large part this might be due to the difficulties of isolating the predictable component of income at the micro level most tests proceed by instrumenting for income but since the available instruments are typically poor such tests might be prejudiced against finding significant excess sensitivity of consumption to income john shea 1995 also it is not clear how closely the resulting econometric predictions of income coincide with agents actual expectations of income to avoid these difficulties this paper examines the response of household consumption to a particular type of income that is both predictable and transitory income tax refunds since a refund depends on events in the previous calendar year it is predictable income as regards consumption in the year of its receipt consequently under the life cycle theory consumption should not increase on receipt of a refund 2 in addition to testing the canonical model of consumption this paper provides estimates interpretable as the marginal propensity to consume mpc out of refunds since federal tax refunds now amount to over 80 billion per year averaging well over 1 000 per refund these estimates are of interest in themselves more generally they bear on the impact of even preannounced and temporary changes in fiscal policy the paper begins by surveying related studies in section i section ii describes the data the consumer expenditure survey cex which of the leading u s micro data sets has the most comprehensive coverage of expenditure the empirical specification is set out in section hi section iv reports the results and section v concludes

the effectiveness of field price discretion empirical evidence from auto lending in many markets it is common for headquarters to create a price list but grant local salespeople discretion to negotiate prices for individual transactions how much if any pricing discretion headquarters should grant is a topic of debate within many firms we investigate this issue using a unique data set from an indirect lender with local pricing discretion we estimate that the local sales force adjusted prices in a way that improved profits by approximately 11 on average a counterfactual analysis shows that using a centralized data driven pricing optimization system could improve profits even further up to 20 over those actually realized this suggests that centralized pricing if appropriately optimized can be more effective than field price discretion we discuss the implications of these findings for auto lending and other industries with similar pricing processes this paper was accepted by serguei netessine operations management

the pricing of revenue assurance a theoretical model to value gross revenue assurance under one of the popular proposals facing u s policy makers is developed the approach makes use of a fundamental paradigm of asset valuation and stochastic calculus because farm level gross revenue is not a traded asset equilibrium arguments must be made to specify the partial differential equation characterizing the value of the assurance an example solution is presented under the assumption of lognormally distributed gross revenue county level data for a variety of crops are used to examine empirically the pricing ability of the model

the failure of competition in the credit card market the bank credit card market containing 4 000 firms and lacking regulatory barriers casually appears to be a hospitable environment for the model of perfect competition nevertheless this article reports that credit card interest rates have been exceptionally sticky relative to the cost of funds moreover major credit card issuers have persistently earned from three to five times the ordinary rate of return in banking during the periods 1983 88 the failure of the competitive model appears to be partly attributable to consumers making credit card choices without taking account of the very high probability that they will pay interest on their outstanding balances copyright 1991 by american economic association

tying odysseus to the mast evidence from a commitment savings product in the philippines we designed a commitment savings product for a philippine bank and implemented it using a randomized control methodology the savings product was intended for individuals who want to commit now to restrict access to their savings and who were sophisticated enough to engage in such a mechanism we conducted a baseline survey on 1777 existing or former clients of a bank one month later we offered the commitment product to a randomly chosen subset of 710 clients 202 28 4 percent accepted the offer and opened the account in the baseline survey we asked hypothetical time discounting questions women who exhibited a lower discount rate for future relative to current trade offs and hence potentially have a preference for commitment were indeed significantly more likely to open the commitment savings account after twelve months average savings balances increased by 81 percentage points for those clients assigned to the treatment group relative to those assigned to the control group we conclude that the savings response represents a lasting change in savings and not merely a short term response to a new product

advertising competition and entry in media industries this paper presents a model of media competition with free entry when media platforms are financed both from advertising receipts and customers subscriptions we establish a relationship between the equilibrium levels of prices advertising and entry the welfare maximizing levels and the advertising technology under constant or increasing returns to scale in the audience size we find an excessive level of entry and an insufficient level of advertising we then extend the analysis along several dimensions the price as a strategic variable on the market for advertising free media platforms and the media quality dimension

implications of rational inattention abstract a constraint that actions can depend on observations only through a communication channel with finite shannon capacity is shown to be able to play a role very similar to that of a signal extraction problem or an adjustment cost in standard control problems the resulting theory looks enough like familiar dynamic rational expectations theories to suggest that it might be useful and practical while the implications for policy are different enough to be interesting

valuing target price support programs with average option pricing the u s government deficiency payment program supplements farm income by transferring income from taxpayers to farmers when revenue lost due to the acreage restriction exceeds revenue gained from participating in the program farmers lose money by participating therefore measuring expected revenue from the government program is important so that farmers can decide whether to participate in the program this study uses a garch average option pricing model and the black average option pricing model to predict the implicit premium of the u s government deficiency payment program the average option pricing model considers the average price of the underlying asset over a fixed period a regression model based on the simulation results is provided so that the average option models can be easily used to project deficiency payments the results can be used by extension economists to help producers decide whether to participate in the program

theory and measurement of exotic options in u s agricultural support programs theoretical models are derived for pricing derivative market instruments with payoff structures identical to those implied by the deficiency findley and loan programs numerical approximation methods are used to obtain market premiums for the exotic contingent claims embedded in these types of programs the application focuses on a comparison of the value of traditional support programs for corn to that of an exchange put offered under the option pilot program the comparison provides measures of expected cost to the government and of the value of the programs to the producer
