the retirement behaviour of the self employed in britain we analyze the retirement behaviour of older self employed workers using a life cycle framework and a multinomial logit model of dynamic employment and retirement choices using data from the two wave retirement survey we find that greater actual or potential earnings decrease the probability of retirement among the self employed in contrast to employees none of gender health or family circumstances appear to affect self employed retirement decisions the dynamic analysis reveals that relatively few employees and virtually no retirees switch into self employment in later life the switches that do occur are motivated less by attempts to use self employment as a bridge job or stepping stone to full retirement than by self employment being a last resort for less affluent workers with job histories of weak attachment to the labour market we compare self employed and employee retirement behaviour and discuss the policy implications of our results

delays in claiming social security benefits this paper focuses on social security benefit claiming behavior a takeup decision that has been ignored in the previous literature using financial calculations and simulations based on an expected utility maximization model we show that delaying benefit claim for a period of time after retirement is optimal in a wide variety of cases and that gains from delay may be significant we find that approximately 10 of men retiring before their 62nd birthday delay claiming for at least one year after eligibility we estimate hazard and probit models using data from the new beneficiary data system to test four cross sectional predictions while the data suggest that too few men delay we find that the pattern of delays by early retirees is generally consistent with the hypotheses generated by our theoretical model

on the determinants of bank interest margins under credit and interest rate risks abstract this paper explores the determinants of optimal bank interest margins based on a simple firm theoretical model under multiple sources of uncertainty and risk aversion the model demonstrates how cost regulation credit risk and interest rate risk conditions jointly determine the optimal bank interest margin decision we find that the bank interest margin is positively related to the bank s market power to the operating costs to the degree of credit risk and to the degree of interest rate risk an increase in the bank s equity capital has a negative effect on the spread when the bank faces little interest rate risk the effect of rising interbank market rate on the spread is ambiguous and depends on the net position of the bank in the interbank market our findings provide alternative explanations for the empirical evidence concerning bank spread behavior

the determination of foreign banking location abstract in this paper we examine the determinants of foreign bank location we initially present some time series data on the postwar expansion of international banking we show that foreign branching increased very rapidly from about 1960 to the mid 1980s and slowed significantly after 1985 one interpretation of this growth in foreign branching is that it largely paralleled the increase in trade and foreign direct investment although it may also have been encouraged by the improvements in communications and the rapid financial innovation of the 1960s and 1970s to assess the role of trade and foreign direct investment on bank expansion we employ a cross sectional analysis of the pattern of foreign bank offices whereas previous studies have focused on a single parent or host country our study extends the existing literature by analyzing the location of nearly 2000 overseas offices across 37 patent and 82 host countries our results suggest a significant relationship between the pattern of bank location trade and foreign direct investment we define a banking centre as one in which there are more foreign banks than can be explained in terms of real business activity and we show that the usa uk switzerland singapore and indonesia most clearly qualify as banking centres we also provide some evidence for a sample of host countries that the abnormal number of bank offices is related to capital market activities

expectations and realizations of work after retirement this paper analyzes a puzzling aspect of retirement behavior known as unretirement nearly 50 percent of retirees follow a nontraditional retirement path that involves partial retirement or unretirement and at least 26 percent of retirees later unretire i explore two possible explanations 1 unretirement transitions result from failures in planning or financial shocks and 2 unretirement transitions are anticipated prior to retirement reflecting a more complex retirement process i show that unretirement was anticipated for the vast majority of those returning to work and is not a result of financial shocks poor planning or low wealth accumulation

job exit behavior of older men a dynamic programming model of job exit behavior and retirement is constructed and estimated using the method of simulated moments the model and estimation method allow for both unobserved individual effects and unobserved job specific match effects the model is estimated using two different assumptions about individual discount factors first a static model with the discount factor equal to zero is estimated then a dynamic model with the discount factor equal to 95 is estimated in both models it is found that bad health age and lack of education increase the probability of retirement the dynamic model performs better than the static model and has different implications for retirement behavior the job specific effects are an important source of unobserved heterogeneity copyright 1991 by the econometric society

what s different among banks abstract based on commercial paper being a nearly perfect substitute for certificates of deposits cds and cd reserve requirements creating a higher cost of funds for banks fama shows that the banking industry must have some monopoly power relative to other financial institutions his analysis does not resolve whether this monopoly power is vested in banks collectively vis a vis other financial institutions or if the monopoly power extends to the level of individual banks using an event study framework to examine the elimination of a reserve requirement we find significant evidence of monopoly power at the level of individual banks

explaining the puzzle of cross state differences in bankruptcy rates abstract bankruptcy rates vary tremendously across states and it is not obvious why the number of candidate explanations is large relative to the number of states to overcome this problem we use zip code level data to identify the importance of demographic variables using within state variation this preserves state level degrees of freedom to identify the impact of state policy variables demographics wage garnishment restrictions and the fraction of bankruptcies filed under chapter 13 explain 70 percent of the variation in filing rates across states exemption rates size of public safety nets and payday loan regulations contribute virtually nothing to the cross state variance in filing rates our findings suggest that state bankruptcy rates reflect the relative costs of filing for formal bankruptcy versus informal default states without effective wage garnishment provisions allow easy informal default furthermore repayment plans mandated under chapter 13 bankruptcy often lead to repeated bank

labor force dynamics of older married couples this article analyzes the dynamics of joint labor force behavior of older couples in the united states using the retirement history survey rhs i analyze the determinants of joint retirement and the effect of one spouse s labor force status on the labor force transitions of the other spouse the results reveal strong associations between the labor force transition probabilities of one spouse and the labor force status of the other spouse these result from structural differences in exit and entry behavior by the spouse s status several lagged endogenous variables have substantial effects on behavior even after controlling for unobserved heterogeneity

public pension programmes and the retirement of married couples in denmark in this paper we study the economic determinants of the joint retirement process of married couples we propose a tractable dynamic discrete choice model for retirement decisions which allows for non trivial saving behaviour we estimate the model on a 1 sample of danish couples of potential retirement age drawn from a population based administrative register the introduction and subsequent reforms of a publicly financed early retirement programme provide us with variation in the data to insure identification of the parameters of interest the elasticities of participation retirement with respect to income flows our estimates imply a significant asymmetry in the sensitivity of retirement behaviour of men and women with respect to variation in their own or their spouse s income flows

are spousal labor supplies substitutes evidence from the workweek reduction policy in china abstract we estimate the effects of spousal labor supply on individuals labor supply by using the implementation of china s 1994 1995 workweek reduction policy as a natural experiment we find that a decrease in the labor supply of wives significantly increased that of husbands but a decrease in the labor supply of husbands had an insignificantly negative effect on that of their wives furthermore a decrease in the labor supply of one spouse reduced the amount of time spent on housework by the other one our findings on the negative relationship between spousal labor supplies differ from those derived from data from developed countries we find evidence that different income levels may be the underlying reason

job exit of men new job destination versus unemployment destination job exit of men over the age of forty is described and analysed using monthly observations derived from the 1988 89 uk retirement survey a competing risks model is described and estimated the results show that tenure and age determine transitions from a job to a new one whereas those transitions from a job to unemployment are also determined by business cycle variables

worktime regulations and spousal labor supply we study interdependencies in spousal labor supply by exploiting the design of the french workweek reduction which introduced exogenous variation in one s spouse s labor supply at constant earnings treated employees work on average two hours less per week husbands of treated women respond by reducing their labor supply by about half an hour consistent with substantial leisure complementarity and specifically cut the non usual component of their workweek leaving usual hours unchanged women s response to their husband s treatment is instead weak and rarely statistically significant possibly due to heavier constraints in the organization of their workweek

personal bankruptcy and credit supply and demand this paper examines how personal bankruptcy and bankruptcy exemptions affect the supply and demand for credit while generous state level bankruptcy exemptions are probably viewed by most policy makers as benefiting less well off borrowers our results using data from the 1983 survey of consumer finances suggest that they increase the amount of credit held by high asset households and reduce the availability and amount of credit to low asset households conditioning on observable characteristics thus bankruptcy exemptions redistribute credit toward borrowers with high assets interest rates on automobile loans for low asset households also appear to be higher in high exemption states

health insurance and retirement of married couples summary most health insurance in the usa is provided by employers until eligibility for public health insurance medicare begins at age 65 retiring before 65 exposes workers who lack retiree health insurance coverage to the risk of catastrophic medical expenditure we solve and estimate a dynamic model of the employment behavior of older married couples that includes risky medical expenditure and health insurance parameter estimates imply that the risk reducing feature of health insurance can account for about half of the observed association between retiree health insurance and employment for married men but can account for only one tenth of the much larger observed association for married women policy simulations imply very small effects on employment of changing the age of eligibility for medicare from 65 to 67 copyright 2006 john wiley sons ltd

do pensions increase the labor supply of older men this paper investigates the relationship between pension coverage and the retirement behavior of older men pensions are associated with higher work involvement for males in their late fifties and early sixties but with lower rates of job holding for those aged 65 69 age of entry into pension employment is shown to be positively correlated with future labor supply when combined with evidence on age specific changes in labor force participation rates this pattern casts doubt on the hypothesis that broadened pension coverage explains a substantial portion of the trend towards earlier male retirement

early retirement and economic incentives in norway early retirement programmes have gradually reduced the retirement age from 67 to 62 for a majority of the labour force based on micro data for 1990 and 1992 we estimate a competing risk model with three states full retirement partial retirement part time work and full time work we then use the estimated model in simulations to study how financial incentives can be strengthened to extend working life financial incentives educational background and industry affiliation are found to influence retirement behaviour for low and medium incomes the tax system shifts the incentives heavily towards early retirement and in particular towards partial retirement combined with part time work

do capital adequacy requirements reduce risks in banking abstract in a dynamic framework it is shown that capital adequacy rules may increase a bank s riskiness in addition to the standard negative effect of rents on risk attitudes of banks a further intertemporal effect has to be considered the intuition behind the result is that under binding capital requirements an additional unit of equity tomorrow is more valuable to a bank if raising equity is excessively costly the only possibility to increase equity tomorrow is to increase risk today

how does equity capital cost affect bank performance during a financial crisis this article theoretically examines how equity capital cost affects return performance and safety of a bank and how this effect varies across a financial crisis comparing to a normal time when the bank manager s performance reveals the like of higher equity return and the dislike of higher equity risk we derive two main results first an increase in the bank s equity capital cost from an increase of the interest rate of the federal funds results in a reduced loan risk taking at an increased optimal bank interest margin implying better bank performance second by ignoring the dislike we find that the better performance is reinforced during a financial crisis but is reduced during a normal time financial crises and the dislike preference as such contribute a relatively low return and the stability of banking activities

borrowing during unemployment unsecured debt as a safety net this paper examines whether unsecured credit markets help disadvantaged households supplement temporary shortfalls in earnings by investigating how unsecured debt responds to unemployment induced earnings losses results indicate that very low asset households those in the bottom decile of total assets do not borrow in response to these shortfalls however other low asset households do borrow increasing unsecured debt by more than 11 cents per dollar of earnings lost in contrast wealthy households do not increase unsecured debt during unemployment the evidence suggests that very low asset households do not have sufficient access to unsecured credit to smooth consumption over transitory unemployment spells

optimal bank interest margin and default risk in equity returns under the return to domestic retail with structural breaks a retrenchment in crossborder credit is under way the product of both market forces and political pressure on international banks to lend at home economist 2009 in addition banks particularly the largest have also dramatically expanded their retail banking operations over the past few years hirtle and stiroh 2007 our goal in this article is to study the effects of default risk on equity returns through bank interest margin management under a renewed focus on domestic retail banking a trend often attributed to the stability of banking activities specifically this article explores the determinants of optimal bank interest margins based on an option based firm theoretical model with multiple sources of structural breaks due to political pressure the model demonstrates how capital regulation and political pressure on foreign lending return and risk conditions jointly determine the optimal bank interest margin decision we show that a more stringent capital requirement is linked with lower eq

financial intermediation and delegated monitoring this paper develops a theory of financial intermediation based on minimizing the cost of monitoring information which is useful for resolving incentive problems between borrowers and lenders it presents a characterization of the costs of providing incentives for delegated monitoring by a financial intermediary diversification within an intermediary serves to reduce these costs even in a risk neutral economy the paper presents some more general analysis of the effect of diversification on resolving incentive problems in the environment assumed in the model debt contracts with costly bankruptcy are shown to be optimal the analysis has implications for the portfolio structure and capital structure of intermediaries

structural models of family labor supply a discrete choice approach a static neoclassical structural model is presented explaining labor supply of both spouses in two adult households in the netherlands family preferences are described with a direct translog utility function with the husbands leisure the wifes leisure and family income as its arguments we assume that the choice set of each family is finite account is taken of the dutch tax and benefits system we allow for hours restrictions and random preferences and account for unobserved wages of nonworkers the models are estimated using smooth simulated maximum likelihood results based upon dutch cross section data from 1987 are illustrated by confidence intervals for elasticities and by several policy simulations excerpt

can social security explain trends in labor force participation of older men in the united states after a long decline the labor force participation rate lfpr of older men in the united states leveled off in the 1980s and began to increase in the late 1990s we examine how changes in social security rules affected these trends we attribute only a small portion of the decline from the 1960s 80s to the increasing generosity of social security over this period increases in the full retirement age and the delayed retirement credit explain one quarter to one half of the recent increase in the lfpr increasing educational attainment and increasing lfpr of married women also contributed to the recent rise

financial contracts and international lending abstract this paper examines alternative financial contracts for international lending i demonstrate that conventional loans can be pareto dominated by financial contracts explicitly incorporating characteristics of the borrower s product market i provide conditions under which commodity linked debt is desirable and determine when more complicated revenue linked loans are optimal i also demonstrate that the type of lending contract has important real effects on production decisions one result of this research is to demonstrate why equity based lending arrangements may have limited applicability

why have the labor force participation rates of older men increased since the mid 1990s this article seeks to explain the substantial increases in older men s labor force participation rates observed since the mid 1990s using data from the united states canada and the united kingdom i exploit the cohort effects driving recent increases in older women s participation rates to identify the effect of a wife s participation decision on her husband s participation decision i then decompose the changes in older married men s participation rates demonstrating that husbands responses to increases in wives participation in the labor force can explain one fourth one half and one third of the increase in the united states canada and the united kingdom respectively

health insurance and the consumer bankruptcy decision evidence from expansions of medicaid abstract anecdotal evidence and several observational studies suggest that out of pocket medical costs are pivotal in a large fraction of consumer bankruptcy decisions in this paper we assess the contribution of medical costs to household bankruptcy risk by exploiting plausibly exogenous variation in publicly provided health insurance using cross state variation in medicaid expansions from 1992 to 2004 we find that a 10 percentage point increase in medicaid eligibility reduces personal bankruptcies by 8 with no evidence that business bankruptcies are similarly affected we interpret our findings with a model in which health insurance imperfectly substitutes for other forms of financial protection and we use the model to present simple calibration results which illustrate how our reduced form parameter estimate affects the optimal level of health insurance benefits we conclude with calculations which suggest that out of pocket medical costs are pivotal in roughly 26 of personal bankruptcies among low income households

economic determinants of workers retirement decisions the landscape for older workers has changed dramatically in recent decades governments have made cuts to public pension programs private pensions have shifted from defined benefit to defined contribution plans equity and housing markets have been unusually volatile and workers have experienced declining morbidity and mortality at the same time the labor force participation rate for older men and women has been rising over the past two decades implying later retirement are these phenomena related this paper reviews the large and growing body of literature exploring the economic determinants of workers retirement decisions including public and private pensions wealth and savings health and health insurance and labor demand

a structural dynamic analysis of retirement behaviour in the netherlands this study focuses on determinants of elderly labour force participation and retirement decisions in the netherlands this is analysed by a dynamic programming model for the simultaneous choice of retirement age and route which includes social insurance and private pensions eligibility conditions for early retirement lifecycle wage and health profiles and layoffs special attention is given to opportunities for and the effect of participation policies results show that institutional structures of benefit and pension programmes are prime determinants of retirement particularly eligibility conditions and potential substitution between exit routes and that dynamic aspects are relevant for understanding retirement behaviour copyright 2004 john wiley sons ltd

labor force dynamics of older men this paper describes and analyzes movements of older men among labor force states in the united states using quarterly observations derived from the retirement history survey rhs the results indicate substantial undercounts in the biannual data indicating that the prevalence of labor force movements at older ages has been underestimated previously the results show that labor force dynamics at older ages are important including duration and spell occurrence dependence and work experience effects these effects are robust to nonparametric controls for unobserved heterogeneity the estimates indicate that social security benefits have strong effects on the timing of labor force transitions at older ages but that changes in social security benefit levels over time have not contributed much to the trend toward earlier labor force exit excerpt

divorce rates and bankruptcy exemption levels in the united states abstractalthough increasing bankruptcy exemption levels protects consumers from negative asset shocks an unintended consequence of this policy that remains unexplored is the effect on divorce rates this effect arises from reducing the benefits of marital risk sharing i establish conditions under which increases in exemption levels lead to more divorce and investigate using data from vital statistics of the united states i estimate that increases in exemption levels occurring between 1989 and 2005 resulted in more than 200 000 additional divorces during this period and that the effect on divorce rates in 2005 is comparable in magnitude to that found for the introduction of unilateral divorce laws by wolfers

understanding joint retirement abstract evidence from different sources shows that spouses retirement decisions are correlated retirement policies affecting individuals in couples are therefore also likely to affect behavior of their spouses it is therefore important to account for joint features in modeling retirement this paper studies a structural collective model of labor supply and retirement of both partners in a couple with interdependent preferences imperfect knowledge of preferences of the spouse and subjective expectations about the future we propose a novel method to estimate preferences and the intra household bargaining process which relies on stated preferences data collected in the health and retirement study respondents were asked to choose between hypothetical retirement trajectories describing the retirement ages and replacement rates of both spouses from three perspectives considering their own preferences only the preferences of their spouse only or the most likely decision for the household with these data all model parameters are identified and potential sources of joint retirement can be disentangled our results suggest that males misperceive their wives preferences overestimating their disutility of work our estimates correct for this we find strong positive correlations between preferences for joint leisure leisure complementarity of the two partners counterfactual simulations with stylized retirement paths suggest that the leisure complementarities explain a substantial part of joint retirement much more than correlation in unobserved heterogeneity or potential wage rates

retirement and consumption in a life cycle model consumption expenditure declines sharply at the time of retirement for many households but the majority maintain a smooth consumption path a simple life cycle model with uncertainty about the time of retirement can account for this pattern a richer version of the model is calibrated to data from the health and retirement study hrs the median change in consumption expenditure at retirement generated by the model is zero while the mean is negative matching the hrs data however the magnitude of the drop in consumption among households that experience a decline is too small in the model compared to the data

correlated default risks and bank regulations bank regulatory design relies critically on bank risk modeling traditionally the bank s aggregate value is assumed to obey an exogenously specified process e g a lognormal diffusion we demonstrate that this assumption is generally invalid given the truncated and correlated payoff structure of individual bank loans instead the bank s aggregate terminal payoff is significantly left fat tailed this skewness remains even when the bank holds an infinitely large number of loans in its portfolio unless they are uncorrelated by ignoring skewness in bank payoffs deposit insurance premia and capital requirements have traditionally been significantly mis calculated

future social security entitlements and the retirement decision abstract a critical question for social security policy is how program incentives affect retirement behavior we use the health and retirement survey hrs to examine the impact of social security incentives on male retirement we implement forward looking models whereby individuals consider the incentives to work in all future years we find that forward looking incentive measures for social security are significant determinants of retirement we also find that private pension incentives have roughly similar effects our findings suggest that social security policies that increase the incentives to work at older ages can significantly reduce the labor force exit rate of older workers

the household bankruptcy decision personal bankruptcy filings have risen from 0 3 percent of households per year in 1984 to around 1 35 percent in 1998 and 1999 transforming bankruptcy from a rare occurrence to a routine event lenders lost about 39 billion in 1998 due to personal bankruptcy filings but economists have little understanding of why households file for bankruptcy or why filings have increased so rapidly until very recently studying the household bankruptcy decision was very difficult because no household level data set existed that included information on bankruptcy filings in this paper we use new data from the panel study of income dynamics which includes information on bankruptcy filings to estimate a model of households bankruptcy decisions we find support for the strategic model of bankruptcy which predicts that households are more likely to file when their financial benefit from filing is higher our model predicts that an increase of 1 000 in households financial benefit from bankruptcy would result in a 7 percent increase in the number of bankruptcy filings our model also predicts that if the 1997 national bankruptcy review commission s proposed changes in bankruptcy exemption levels were implemented there would be a 16 percent increase in the number of bankruptcy filings each year but if the 100 000 cap on homestead exemptions recently passed by the u s senate were adopted our model predicts that there would be only a negligible effect on the number of filings we find little support for the nonstrategic model of bankruptcy which predicts that households file when adverse events occur which reduce their ability to repay finally controlling for state and time fixed effects our model shows that households are more likely to file for bankruptcy if they live in districts with higher aggregate filing rates

multivariate mixed proportional hazard modelling of the joint retirement of married couples we analyse the joint distribution of the durations until retirement of danish husbands and wives we estimate a multivariate mixed proportional hazards model that allows for interdependence in the times to retirement of spouses we find evidence of strong complementarities in leisure times symmetrically for husband and wife low own income and poor health are found to induce individual retirement prior to spouse s retirement whereas low spousal income is not and neither party is found likely to substitute own for purchased care when the spouse is in poor health furthermore high wealth and low income are found to spur joint simultaneous retirement copyright 2004 john wiley sons ltd

the effects of health wealth and wages on labour supply and retirement behaviour this paper estimates a life cycle model of labour supply retirement and savings behaviour in which future health status and wages are uncertain individuals face a fixed cost of work and cannot borrow against future labour pension or social security income the method of simulated moments is used to match the life cycle profiles of labour force participation hours worked and assets that are estimated from the data to those that are generated by the model the model establishes that the tax structure of the social security system and pensions are key determinants of the high observed job exit rates at ages 62 and 65 removing the tax wedge embedded in the social security earnings test for individuals aged 65 and older would delay job exit by almost one year by contrast social security benefit levels health and borrowing constraints are less important determinants of job exit at older ages for example reducing social security benefits by 20 would cause workers to delay exit from the labour force by only three months

job search requirements for unemployed at the end of working life effects on unemployment dynamics and self employment probabilities this paper investigates the extent to which job search requirements in unemployment insurance u i increase the probability of self employment as a retirement route for causal identification we apply a difference in differences approach using a dutch 2004 policy reform that introduced job search requirements in u i for persons aged 57 5 and older unemployment dynamics and self employment probabilities are studied using a dynamic multinomial logit model with unobserved heterogeneity the results suggest that job search requirements stimulated people to exit unemployment and discouraged older workers to enter unemployment the probability of self employment as an exit route to retirement increased relative to u i but not relative to paid employment

how social security and medicare affect retirement behavior in a world of incomplete markets this paper provides an empirical analysis of how the u s social security and medicare insurance system affect the labor supply of older males in the presence of incomplete markets for loans annuities and health insurance we estimate a detailed dynamic programming dp model of the joint labor supply and social security acceptance decision focusing on a sample of males in the low to middle income brackets whose only pension is social security the dp model delivers a rich set of predictions about the dynamics of retirement behavior and comparisons of actual vs predicted behavior show that the dp model is able to account for wide variety of phenomena observed in the data including the pronounced peaks in the distribution of retirement ages at 62 and 65 the ages of early and normal eligibility for social security benefits respectively we identify a significant fraction of health insurance constrained individuals who have no form of retiree health insurance other than medicare and who can only obtain fairly priced private health insurance via their employer s group health plan the combination of significant individual risk aversion and a long tailed pareto distribution of health care expenditures implies that there is a significant security value for these individuals to remain employed until they are eligible for medicare coverage at age 65 overall our model suggests that a number of heretofore puzzling aspects of retirement behavior can be viewed as artifacts of particular details of the social security rules whose incentive effects are especially strong for lower income individuals and those who do not have access to fairly priced loans annuities and health insurance

disability benefit generosity and labor force withdrawal abstract a key component for estimating the optimal size and structure of disability insurance di programs is the elasticity of di claiming with respect to benefit generosity yet in many countries including the united states all workers face identical benefit schedules which are a function of one s labor market history making it difficult to separate the effect of the benefit level from the effect of unobserved preferences for work on individuals claiming decisions to circumvent this problem we exploit exogenous variation in di benefits in austria arising from several reforms to its di and old age pension system in the 1990s and 2000s we use comprehensive administrative social security records data on the universe of austrian workers to compute benefit levels under six different regimes allowing us to identify and precisely estimate the elasticity of di claiming with respect to benefit generosity we find that over this time period a 1 increase in potential di benefits was associated with a 1 2 increase in di claiming

term limits and electoral competitiveness evidence from california s state legislative races california s legislative term limits have dramatically reduced campaign expenditures real expenditures during the three general elections after the term limits initiative passed in 1990 were lower than in even 1976 this drop has occurred at the same time that races have become closer contests and more candidates are running for office by any measure term limits have coincided with large changes in the level of political competition even before term limits have forcibly removed a single politician from office the changes are so large that more incumbents are being defeated races are closer more candidates are running and fewer single candidate races than occur at any other time during our sample period from 1976 to 1994

the politics of bank failures evidence from emerging markets this paper studies large private banks in 21 major emerging markets in the 1990s it first demonstrates that bank failures are very common in these countries about 25 percent of these banks failed during the seven year sample period the paper also shows that political concerns play a significant role in delaying government interventions to failing banks failing banks are much less likely to be taken over by the government or to lose their licenses before elections than after this result is robust to controlling for macroeconomic and bank specific factors a new party in power early elections outstanding loans from the imf as well as country specific time independent factors this finding implies that much of the within country clustering in emerging market bank failures is directly due to political concerns

a structural retirement model the life cycle model analyzed here constrains most work on the main job to be full time partial retirement entails a wage reduction and frequently a job change maximum likelihood estimates of utility function parameters are designed to incorporate information on the age of leaving full time work and the age of full retirement the model closely tracks retirement behavior including peaks in retirement activity at 62 and 65 the paper explores the relation of these peaks to nonlinearities in the budget constraint created by various retirement programs policy analyses based on this and on earlier models with simpler structures are compared the retirement choice is one of the more prominent manifestations of life cycle behavior the decision is the result of an interplay between an individual s preferences and a set of incentives which change in complicated ways as the individual progresses through his or her late 50 s and 60 s the purpose of this study is to formulate and estimate a structural model which incorporates in a fundamental way this interplay between lifetime preferences and incentives and to illustrate how such a model may be used to investigate retirement behavior a structural model of this type is essential for analyzing potential policy changes which can be expected to affect incentives in varying ways over a number of years in the life cycle the current study incorporates two structural features which have frequently been omitted from previous studies first the model requires that an individual who wishes to reduce work effort below full time must accept a reduced hourly wage rate in order to do so this reflects empirical evidence from micro data sets which indicates that around one third of older individuals engage in part time work at one time or another and that regardless of whether or not these older workers change jobs to obtain part time work they usually take wage cuts as compared to their previous full time work 2 the fact that an individual is willing to accept a lower wage rate in return for the opportunity to work fewer than full time hours contains important information about the preferences of the

government bailouts and default risks of a duopoly strong bank versus weak bank a duopolistic loan market includes a strong bank without the problem of early closure that opts out of government bailouts and a weak bank with this problem that participates in the bailout programmes of distressed loan purchases and direct equity injections a direct implication of our framework is that the strong bank s equity will be priced as a standard call option while the weak bank s equity will be priced as a down and out call option we find that an increase in either bailout i e distressed loan purchases and direct equity injections directly decreases the weak bank s default risk but indirectly increases the strong bank s default risk accordingly either bailout contributes to banking stability since the indirect positive effect insufficiently offsets the direct negative effect giving an overall negative response of default risks to an increase in either bailout higher competition by shifting to quasi competition from collusion increases banking stability under either bailout our analysi

social security and two earner households in the past decades elimination of the pay as you go system in u s has been extensively discussed and studied such an elimination would also eliminate the intra cohort redistribution done by the following policies of social security due to spousal and survivor s beneflt provisions the system redistributes mostly to single earner married households not necessarily progressive retirement beneflts are a concave function of past mean earnings hence the system redistributes from high earners to low earners finally the existence of a cap on social security taxable earnings makes the system regressive this is the flrst paper that quantifles redistributive labor supply and welfare implications of these policies using a general equilibrium life cycle model agents start out as permanently married or single and with education levels and wage proflles where the latter depend both on education and gender the household is the decision maker and decides on the labor supply of its member s and saving the aggregate production function has as inputs capital and labor aggregated by e ciency elimination of these policies results in a 6 1 increase in married female labor force participation rate the middle income single earner married households experience the largest welfare losses whereas the high income two earner households together with high income single households experience the largest welfare gains

redistributive taxation and personal bankruptcy in u s states abstract personal bankruptcy regulation and redistributive taxes and transfers vary considerably across u s states and over time our hypothesis is that both policies are imperfect substitutes in insuring consumption of risk averse agents in incomplete markets exploiting data variation over time for 18 u s states for the period 1980 2003 we find considerable support for this hypothesis redistributive taxation and bankruptcy exemptions are negatively correlated and both policies are associated with more equal consumption growth

optimal bank interest margin under capital regulation and deposit insurance this paper examines the relationships among capital regulation deposit insurance and the optimal bank interest margin in a model where loan losses are the source of uncertainty changes in capital regulation or deposit insurance premiums have direct effects on the bank s interest margin an increase in bank capital requirement or in deposit insurance premiums results in a reduced interest margin under nonincreasing risk aversion comparative static analysis also explores the relation between asset quality and interest margin it is shown that a mean preserving spread of the distribution of loan losses results in a reduced margin

income and outcomes a structural model of intrahousehold allocation there is evidence from several sources that one cannot treat many person households as a single decision maker if this is the case then factors such as the relative incomes of the household members may affect the final allocation decisions made by the household we develop a method of identifying how incomes affect outcomes given conventional family expenditure data the basic assumption we make is that household decision processes lead to efficient outcomes we apply our method to a sample of canadian couples with no children we find that the final allocations of expenditures on each partner depend significantly on their relative incomes and ages and on the level of lifetime wealth

the political economy of property exemption laws abstract exemption laws enable people who default on loans to protect certain assets from liquidation every state has its own set of exemption laws and they vary widely the 1978 federal bankruptcy law contains a set of national exemptions which debtors in bankruptcy are permitted to use instead of their state s exemptions unless the state has formally opted out of the federal system we contend that states decisions to opt out shed light on their exemption levels we find that states are more likely to opt out if their state exemption is lower than the federal exemption and that states are more likely to opt out if they also have a high bankruptcy filing rate and transfer little money to the poor these latter findings suggest that studies that examine the impact of exemptions on for example the bankruptcy rate should not treat exemption levels as exogenous variables

back to work expectations and realizations of work after retirement this paper analyzes a puzzling aspect of retirement behavior known as unretirement nearly 50 percent of retirees follow a nontraditional retirement path that involves partial retirement or unretirement and at least 26 percent of retirees later unretire i explore two possible explanations 1 unretirement transitions result from failures in planning or financial shocks and 2 unretirement transitions are anticipated prior to retirement reflecting a more complex retirement process i show that unretirement was anticipated for the vast majority of those returning to work and is not a result of financial shocks poor planning or low wealth accumulation
