the effect of taxes on labor supply in the underground economy this paper uses micro data from a randomized survey carried out in the metropolitan area of quebec city canada to analyze the decision to evade taxes and work in the underground economy the results indicate that taxes distort labor market activities away from the regular sector to the underground sector but the distortion is small for the average worker the distortion is large however for particular groups of the population such as welfare claimants copyright 1994 by american economic association

a theory of corporate financial decisions with liquidity and solvency concerns this paper studies the impact of both liquidity and solvency concerns on corporate finance i present a tractable model of a firm that optimally chooses capital structure cash holdings dividends and default while facing cash flows with long term uncertainty and short term liquidity shocks the model explains how changes in solvency affect liquidity and also how liquidity concerns affect solvency via capital structure choice these interactions result in a dynamic cash policy in which cash reserves increase in profitability and are positively correlated with cash flows the optimal dividend distributions implied by the model are smoothed relative to cash flows i also find that liquidity concerns lead to a decrease of dispersion of credit spreads

value creation management competencies and global corporate citizenship an ordonomic approach to business ethics in the age of globalization this article develops an ordonomic approach to business ethics in the age of globalization through the use of a three tiered conceptual framework that distinguishes between the basic game of antagonistic social cooperation the meta game of rule setting and the meta meta game of rule finding discourse we address three questions the answers to which we believe are crucial to fostering effective business leadership and corporate social responsibility first the purpose of business in society is value creation companies have a social mandate to organize mutually advantageous cooperation second business ethics should teach the management competencies necessary to fulfill business s societal mandate these competencies are optimization competence in the basic game of value creation governance competence in the meta game of political rule setting and the three discourse related skills of orientation competence reception competence and communication competence necessary for engaging in the meta meta game third companies can help solve global problems through global corporate citizenship if they participate as political and moral actors in rule setting processes and rule finding discourse aimed at laying the foundation for value creation on a global scale

u s ceos of sbus in luxury goods organizations a mixed methods comparison of ethical decision making profiles this study involved using a mixed method research design to examine the moral philosophy difference between the ethical decision making process of ceos in u s led and non u s led within the luxury goods industry the study employed a manova to compare the ethical profiles between the two leader types us and non us led and a phenomenological qualitative process to locate themes that give indication as to the compatibility of the luxury strategy values and practices with the principles and concepts of responsible leadership and conscious capitalism as the luxury goods industry is facing the first slowdown since 2000 pressure to achieve sales targets in the u s to make up for losses in other markets will place these ceos under extreme pressure from their headquarters these leaders must possess the ethical decision making capability to balance legal and moral dilemmas unique to multinational luxury goods organizations while delivering business results in a challenging environment results of the study show no evidence of difference in the ethical decision making profiles between the two groups of leaders the themes and emergent findings resulting from the qualitative analysis indicate a profound incompatibility between the values informing decision makers using the luxury strategy and those employed by leaders operating within the principles and parameters of responsible leadership and conscious capitalism recommendations for future research include replicating the study with a larger sample within a different geographic region or comparing leaders using the luxury strategy to those using conscious capitalism

can the trade off theory explain debt structure we examine the optimal mixture and priority structure of bank and market debt using a tradeoff model where banks have the unique ability to renegotiate outside formal bankruptcy flexible bank debt offers a superior tradeoff between tax shields and bankruptcy costs ease of renegotiation limits bank debt capacity however optimal debt structure hinges upon which party has bargaining power in private workouts weak firms have high bank debt capacity and utilize bank debt exclusively strong firms lever up to their lower bank debt capacity augment with market debt and place the bank senior therefore the tradeoff theory offers an explanation for i why young small firms use bank debt exclusively ii why large mature firms employ mixed debt financing and iii why bank debt is senior the tradeoff theory also generates predictions consistent with international evidence in countries where the bankruptcy regime entails soft tough enforcement of contractual priority bank debt capacity is low high implying greater less reliance on market debt

state capitalism and performance persistence of business group affiliated firms a comparative study of china and india business groups emerged in developing economies through direct or indirect support from the state in order to overcome a variety of institutional voids and or to further state objectives of economic growth however the efficacy of this organizational form and its associated governance structures have been debated given the dual possibility of business groups to allocate resources among its affiliates for cross subsidization or winner picking we argue that elements of the institutional environment comprising of the state s approach to organizations and the political context of these interactions vary across countries thereby influencing business groups resource allocation strategies and affecting the persistence of affiliated firms superior performance contrasting the types of state capitalism in china and india we develop and test our hypotheses we find that the effect of business group affiliation on firms superior performance persistence is stronger in a state led system of state capitalism e g china than in a co governed system e g india and that this divergence of the business group effect is weakened as affiliated firms internationalize our findings have implications for understanding business groups across institutional contexts and the influence of diversity in the types of state capitalism on organizational strategies

an analytical approximate solution to the problem of precautionary savings abstract this paper considers the problem of precautionary savings for an expected utility specification with finite horizon the exact solution is known for only a few cases numerical methods have limited applications because of bellman s curse of dimensionality this paper derives a simple analytical approximate solution for a general specification of the felicity function which is linear in the variance of the innovations on human wealth numerically the approximation is very accurate for realistic values of the parameters of the problem

asset redeployability liquidation value and endogenous capital structure heterogeneity firms with lower leverage are not only less likely to experience financial distress but are also better positioned to acquire assets from other distressed firms with endogenous asset sales and values each firm s debt choice then depends on the choices of its industry peers with indivisible assets otherwise identical firms may adopt different debt policies with some choosing highly levered operations to take advantage of ongoing debt benefits and others choosing more conservative policies to wait for acquisition opportunities our key empirical implication is that the acquisition channel can induce firms to reduce debt when assets become more redeployable

agency and optimal investment dynamics agency problems limit firms access to capital markets curbing investment firms and investors seek contractual ways to mitigate these problems what are the implications for investment we present a theory of a firm s investment dynamics in the presence of agency problems and optimal long term financial contracts we derive results relating firms investment decisions current and past cash flows firm size capital structure and dividends among the results optimal investment is increasing in current and past cash flow and optimal investment is positively serially correlated over time after controlling for investment opportunities these results hold for a range of agency problems jel g30 g31 g32 g35 d82 d86 d92 copyright 2007 oxford university press

precautionary behavior migrant networks and household consumption decisions an empirical analysis using household panel data from rural china abstract we develop a test of precautionary behavior in the consumption decisions of rural agricultural households among surveyed households facing a median level of consumption risk 10 of savings can be attributed to a precautionary motive and this increases to 15 for households with consumption per capita below the poverty line we next use distant lags of local rainfall shocks uncorrelated with current consumption growth to identify the size of migrant networks outside the village and then present evidence that both poor and nonpoor households engage in less precautionary saving as the size of the village migrant network increases

optimal portfolio choice for long horizon investors with nontradable labor income this paper examines how risky labor income and retirement affect optimal portfolio choice with idiosyncratic labor income risk the optimal allocation to stocks is unambiguously larger for employed investors than for retired investors consistent with the typical recommendations of investment advisors increasing idiosyncratic labor income risk raises investors willingness to save and reduces their stock portfolio allocation towards the level of retired investors positive correlation between labor income and stock returns has a further negative effect and can actually reduce stockholdings below the level of retired investors financial advisors typically recommend that their customers invest more in stocks than in safe assets when they are working and to shift their investments towards safe assets when they retire jagannathan and kocherlakota 1996 malkiel 1996 by contrast the standard academic models of portfolio choice merton 1969 1971 samuelson 1969 show that retirement is irrelevant for portfolio decisions if investment opportunities are constant and human capital is tradable in this case the fraction of wealth optimally invested in risky assets should be constant over the lifetime of an individual recent research building on the pioneering work by merton 1971 shows that time varying investment opportunities result in portfolio rules with an intertemporal hedging component whose magnitude depends on the investment horizon of the investor kim and omberg 1996 balduzzi and lynch 1997 brennan schwartz and lagnado 1997 brandt 1999 campbell and viceira 1999 2001 barberis 2000 with time variation in investment opportunities retirement and death play an instrumental role as events that exogenously fix the individual s investment horizon more importantly retirement also marks the time at which individuals stop working and thereafter must live off their lifetime savings and possibly transfers from this perspective retirement matters for portfolio choice

entrepreneurial finance and nondiversifiable risk w e develop a dynamic incomplete markets model of entrepreneurial firms and demonstrate the implications of nondiversifiable risks for entrepreneurs interdependent consumption portfolio allocation financing investment and business exit decisions we characterize the optimal capital structure via a generalized tradeoff model where risky debt provides significant diversification benefits nondiversifiable risks have several important implications more risk averse entrepreneurs default earlier but choose higher leverage lack of diversification causes entrepreneurial firms to underinvest relative to public firms and risky debt partially alleviates this problem and entrepreneurial risk aversion can overturn the risk shifting incentives induced by risky debt we also analytically characterize the idiosyncratic risk premium jel g11 g31 e20

household production and the excess sensitivity of consumption to current income empirical research on the permanent income hypothesis pih has found that consumption growth is excessively sensitive to predictable changes in income this finding is interpreted as strong evidence against the pih we propose an explanation for apparent excess sensitivity that is based on a quantitative equilibrium model of household production in which permanent income consumers respond to shifts in sectoral wages and prices by substituting work effort and consumption across home and market sectors although the pih is true this mechanism generates apparent excess sensitivity because market consumption responds to predictable income growth

the family as an incomplete annuities market families can self insure against uncertain dates of death through implicit or explicit agreements with respect to consumption and interfamily transfers interfamily transfers need have nothing to do with altruistic feelings they may simply reflect risk sharing behavior of completely selfish family members although family annuity markets are incomplete even small families can substitute by more than 70 percent for perfect market annuities given adverse selection and transaction costs family risk pooling may be preferred to public market annuities in the absence of public annuities these risk sharing arrangements provide powerful incentives for marriage and family formation

precaution and liquidity in the demand for housing we exploit cross sectional mortgage data to investigate the importance of liquidity constraints and a precautionary motive in the demand for housing households that are not liquidity constrained consume housing services essentially as the life cycle hypothesis suggests but with a significant precautionary component households that are liquidity constrained in terms of not meeting standard loan to value or payments to income constraints are similar to unconstrained households in most respects including the precautionary motive but they respond somewhat less to fluctuations in their lifetime income suggesting some influence of bank induced liquidity constraints we additionally find however that banks enforce liquidity constraints only weakly jel d91 d12 r21 i introduction the benchmark theory in the economics of consumption is the life cycle or permanent income hypothesis lcpi based on the work of modigliani and brumberg 1954 and friedman 1957 its empirical validity is sometimes questionable especially when compared against alternatives that incorporate liquidity constraints or the precautionary motive for saving see for instance deaton 1992 for a survey rejection of the lcpi may however be just a manifestation of the poor quality of consumption data at the micro level these data are typically subject to the reporting biases and omissions inherent in consumer surveys there are further difficulties in measuring a desired stream of consumption services nondurable consumption goods are a small fraction of total consumption and in the case of food essentials hardly a consumer choice variable durable consumption goods have the feature that they are lumpy and that the consumption services at any point in time are hard to measure we propose to test the lcpi at the micro level with a quite different type of data the data are obtained from the residential mortgage finance database collected by the national association of realtors they are based on actual home purchases and the associated mortgage transactions reported by realtors and thus avoid some of the reporting biases of the consumer surveys more important they allow us to accurately identify households that in principle have instantaneous access to additional liquidity by lowering the down payment for the house purchase or increasing the size of the loan further the purchase of a house provides an accurate measure of a relatively large fraction of consumption services obtained for a medium to long horizon and measured at the time of the consumption decision although our data also have some serious shortcomings they allow a look at the lcpi from an unconventional vantage point perhaps the most influential study employing the standard consumer survey in testing the lcpi at the micro level is that of hall and mishkin 1982 it examines food expenditure from the panel study of income dynamics one of their key results is that consumption tracks income more closely than would be expected under the lcpi they demonstrate that this result could be explained by assuming a group of liquidity constrained consumers consuming their income at each point in time of 20 of the total sample some of the drawbacks of this study are the use of food expenditures to represent consumption the underreporting of income and absence of proper wealth data inherent in the consumer survey and the associated inability to individually separate liquidity constrained consumers from the rest of the sample several previous studies have attempted to improve on this way of testing the lcpi by examining other data sets bernanke 1984 used data on durable consumption goods automobiles to overcome the drawbacks of using food consumption in the hall and mishkin study his results support the lcpi but are still suspect because of possible reporting biases and the lack of good wealth and savings observations

individual morality and reputation costs as deterrents to tax evasion abstract empirical evidence suggests some taxpayers never evade evasion increases with the tax rate and evasion decisions are interdependent these findings are not easily explained by the existing theory which models evasion as an independently made amoral gamble this paper uses nonpecuniary costs of evasion to reconcile theory with evidence once individuals are assumed to differ by an honesty characteristic taxpayers dichotomise into groups the more honest of which responds to a tax change as the evidence suggests a further extension is to introduce an endogenous reputation cost this suggests a positive relationship between the number of evaders and the tax rate

life cycle consumption under social interactions abstract in this paper we examine how social interactions affect consumption decisions at various levels of aggregation in a life cycle economy made up of peer groups for this purpose we consider two analytically solvable life cycle models one under certainty equivalent behavior and one under prudence and explicitly allow for three different forms of social interactions in peer groups namely conformism altruism and jealousy we show that whether social interactions have any effects on individuals optimal consumption decisions critically depends on intertemporal rather than static considerations this is true regardless of whether individuals preferences are time separable or exhibit habit formation and whether information within peer groups is homogeneous or disparate it implies that analyzing the effects of social interactions in static rather than intertemporal settings is likely to be misleading we also show that social interactions when coupled with either habit formation or prudence can significantly strengthen the effects of habit formation or prudence in the direction of resolving two well known puzzles in the literature on the permanent income hypothesis namely excess smoothness and excess sensitivity

the permanent income hypothesis estimation and testing by instrumental variables the permanent income hypothesis with rational expectation is restated estimated and tested by an instrumental variables technique on the postwar u s aggregate time series data the hypothesis is accepted on a consumption series which includes service flows from consumer durables if the consumption series is the one in the national income and product accounts the hypothesis is decisively rejected an explanation is suggested to reconcile the conflicting test results

family labor supply and asset returns abstract we study how shocks to wages and asset prices affect consumption and labor supply decisions of two earner households in a life cycle framework with housing and flexible preferences we provide a micro foundation of the wealth effects on consumption and labor supply we find evidence for non separability between non durable consumption housing services and hours of work the results also highlight the importance of family labor supply in understanding how households respond to shocks to financial and housing markets

equilibrium consumption and precautionary savings in a stochastically growing economy abstract the derivation of a closed form solution for consumption based on the constant elasticity utility function in the presence of stochastic labor income has proved to be intractable this paper derives a closed form equilibrium relationship between consumption and wealth one that holds along a balanced growth path in a stochastic romer endogenous growth model by employing more general recursive preferences we can disentangle the coefficient of relative risk aversion from the intertemporal elasticity of substitution the effects of key structural parameters on equilibrium consumption and its tradeoff with leisure are analyzed a significant aspect of our analysis concerns the extent to which current risk in the economy is shared between labor and capital this plays an important role in determining the impact of risk on the economy in general and on consumption in particular formal analysis is supplemented with extensive numerical simulations

dynamic security design convergence to continuous time and asset pricing implications an entrepreneur with limited liability needs to finance an infinite horizon investment project an agency problem arises because she can divert operating cash flows before reporting them to the financiers we first study the optimal contract in discrete time this contract can be implemented by cash reserves debt and equity the latter is split between the financiers and the entrepreneur and pays dividends when retained earnings reach a threshold to provide appropriate incentives to the entrepreneur the firm is downsized when it runs short of cash we then study the continuous time limit of the model we prove the convergence of the discrete time value functions and optimal contracts our analysis yields rich implications for the dynamics of security prices stock prices follow a diusion reflected at the dividend barrier and absorbed at zero their volatility as well as the leverage ratio of the firm increase after bad performance stock prices and book tomarket ratios are in a non monotonic relationship a more severe agency problem entails lower price earning ratios and firm liquidity and higher default risk

job matching and the wage distribution this paper brings together the microeconomic labor and the macroeconomic equilibrium views of matching in labor markets we nest a job matching model a la jovanovic 1984 into a mortensen and pissarides 1994 type equilibrium search environment the resulting framework preserves the implications of job matching theory for worker turnover and wage dynamics and it also allows for aggregation and general equilibrium analysis we obtain two new equilibrium implications of job matching and search frictions for wage inequality first learning about match quality and worker turnover map gaussian output noise into an ergodic wage distribution of empirically accurate shape unimodal skewed with a paretian right tail second high idiosyncratic productivity risk hinders learning and sorting and reduces wage inequality the equilibrium solutions for the wage distribution and for the aggregate worker flows quits to unemployment and to other jobs displacements hires provide the likelihood function of the model in closed form

optimal security design and dynamic capital structure in a continuous time agency model we derive the optimal dynamic contract in a continuous time principal agent setting and implement it with a capital structure credit line long term debt and equity over which the agent controls the payout policy while the project s volatility and liquidation cost have little impact on the firm s total debt capacity they increase the use of credit versus debt leverage is nonstationary and declines with past profitability the firm may hold a compensating cash balance while borrowing at a higher rate through the credit line surprisingly the usual conflicts between debt and equity asset substitution strategic default need not arise in this paper we consider a dynamic contracting environment in which a riskneutral agent or entrepreneur with limited resources manages an investment activity while the investment is profitable it is also risky and in the short run it can generate arbitrarily large operating losses the agent will need outside financial support to cover such losses and continue the project the difficulty is that while the probability distribution of the cash flows is publicly known the agent may distort these cash flows by taking a hidden action that leads to a private benefit specifically the agent may i conceal and divert cash flows for his own consumption and or ii stop providing costly effort which would reduce the mean of the cash flows therefore from the perspective of the principal or investors that fund the project there is the concern that a low cash flow realization may be a result of the agent s actions rather than the project s fundamentals to provide the agent with appropriate incentives investors control the agent s wage and may also withdraw their financial support for the project and force its early termination we seek to characterize an optimal contract in this framework and relate it to the firm s choice of capital structure we develop a method to solve for the optimal contract given the incentive constraints in a continuous time setting and study the properties of the credit line debt and equity that implement the contract as in the discrete time model of demarzo and fishman 2003 the continuous time setting offers several peter m demarzo is from stanford university and yuliy sannikov is from u c berkeley we

optimal saving rules for loss averse agents under uncertainty abstract most empirical studies assume only monotonic preferences for households behavioral research however provides substantial evidence that preferences for wealth are measured relative to a reference point in this paper we introduce and solve a two period consumption and savings model for a loss averse agent who measures utility from consumption relative to a benchmark level the solution is given as a parametric decision rule with one unknown parameter that depends on the distribution of the return on saving we find non linearity in the fraction of wealth saved where the specific saving pattern depends on the sign of the real return on savings the amount of saving is nondecreasing in initial wealth and the riskiness of the return distribution

tax evasion with labour income allingham and sandmo s 1972 classic paper on tax evasion set out a simple framework for looking at the effects of regular tax parameters and of the structure of penalties on the amount of tax dodging carried out by a tax evader subsequent papers have enriched the basic model of individual behaviour and have attempted to adduce some empirical evidence 2 but with few exceptions the essential nature of the assumed underlying problem has remained the same how much income shall i reveal to the authorities in the face of the known penalties and the known possibility of getting caught whilst this approach is useful for some types of tax evasion by individuals it is clearly inappropriate for others such as the phenomenon of working off the books rather than concealing a portion of a uniform lump of income that is undistinguished as to its source the person cheats the government by taking one or more different jobs either in addition to or as a replacement for his regular employment the income from which is administratively difficult to tax this paper examines the implications of the possible diversity of form of the tax evasion problem for the analysis of the fundamental questions which allingham and sandmo addressed the effect of government instruments on the incentives to participate in legal and illegal work activities to do this we must concentrate on one major development of the original model namely that where income is endogenous in effect we construct a particular version of the analysis of labour supply under uncertainty within which to

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

why is consumption so smooth for thirty years it has been accepted that consumption is smooth because permanent income is smoother than measured income this paper considers the evidence for the contrary position that permanent income is in fact less smooth than measured income so that the smoothness of consumption cannot be straightforwardly explained by permanent income theory the paper argues that in postwar u s quarterly data consumption is smooth because it responds with a lag to changes in income

the impact of debt financing on entry and exit in a duopoly this article investigates the interaction between market entry company foreclosure and capital structure in a duopoly we find that the order in which firms foreclose is determined not only by differences in firm specific factors but also by common economic factors such as the interest rate and the market profit volatility we extend the exit model by allowing financially distressed firms to renegotiate their debt contracts through a one off debt exchange offer we find that firms with high bankruptcy costs or with prospects of profit improvement can get bigger reductions on their debt repayments investigating market entry we find that financial vulnerability of the incumbent induces earlier entry article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

liquidity default liquidity management and smooth dividends policy abstractour article models liquidity financing constraints with the real options framework by conducting a comprehensive investigation of the effects of shocks to liquidity constraints on the firm s optimal investment financing and dividend policies our model highlights the importance of liquidity management and extends the liquidity management approach to hedge liquidity default risk we find that being concerned about liquidity default risk will significantly change a firm s behaviours including those related to investment and the optimal capital structure a firm that is concerned about its liquidity default risk will become more cautious it will choose to delay investment and have higher leverage when internal liquidity is very low but choose earlier investment and lower leverage when liquidity is high enough the dividends policy can alleviate risks from both the external market and internal project volatility and provides an alternative explanation for the smooth dividends policy puzzle comm

optimal consumption and portfolio policies when asset prices follow a diffusion process abstract we consider a consumption portfolio problem in continuous time under uncertainty a martingale technique is employed to characterize optimal consumption portfolio policies when there exist nonnegativity constraints on consumption and on final wealth we also provide a way to compute and verify optimal policies our verification theorem for optimal policies involves a linear partial differential equation unlike the nonlinear partial differential equation of dynamic programming the relationship between our approach and dynamic programming is discussed we demonstrate our technique by explicitly computing optimal policies in a series of examples in particular we solve the optimal consumption portfolio problem for hyperbolic absolute risk aversion utility functions when the asset prices follow a geometric brownian motion the optimal policies in this case are no longer linear when nonnegativity constraints on consumption and on final wealth are included by these examples one can see that our approach is much easier than the dynamic programming approach

idiosyncratic return volatility cash flows and product market competition over the past 40 years the volatility of the average stock return has drastically outpaced total market volatility thus idiosyncratic return volatility has dramatically increased we estimate this increase to be 6 per year consistent with an efficient market this result is mirrored by an increase in the idiosyncratic volatility of fundamental cash flows we argue that these findings are attributable to the more intense economy wide competition various cross sectional and time series tests support this idea economic competitiveness facilitates reinterpretation of the results from the cross country r2 literature as well as the us idiosyncratic risk literature jel g12 g14

short term debt and incentives for risk taking abstract we challenge the view that short term debt curbs moral hazard and demonstrate that in a world with financing frictions and fair debt pricing short term debt generates incentives for risk taking to do so we develop a model in which firms are financed with equity and short term debt and cannot freely optimize their default decision because of financing frictions we show that when firms are close to distress the dynamic interaction of operating and rollover losses fuels default risk in such instances shareholders find it optimal to increase asset risk to improve interim debt repricing and prevent inefficient liquidation these risk taking incentives do not arise when debt maturity is sufficiently long

precautionary savings and the permanent income hypothesis this paper derives the explicit solution of a dynamic stochastic optimal consumption problem for infinitely lived agents whose preferences exhibit in the presence of non diversifiable labour income uncertainty a constant elasticity of intertemporal substitution and constant absolute risk aversion the constancy of the elasticity of intertemporal substitution which implies that marginal utility at zero consumption is infinite guarantees that the non negativity constraint on consumption is never binding along the optimal path the assumption of constant absolute risk aversion allows an explicit computation of human wealth and provides a simple representation of the precautionary savings motive

the shadow costs of repos and bank liability structure making use of a structural model that allows for optimal liquidity management we study the role that repos play in a bank s financing structure in our model the bank s assets consist of illiquid loans and liquid reserves and are financed by a combination of repos long term debt deposits and equity repos are a cheap source of funding but they are subject to an exogenous rollover risk we show that the use of repos inflicts two types of indirect shadow costs on the bank s shareholders first it induces the bank to maintain higher liquid reserves in order to alleviate the additional default risk second it adds to the cost of long term debt financing these shadow costs limit the bank s appetite for cheap but unstable repo funding this effect is however weakened under poor returns on risky assets access to deposit funding and the depositor preference rule we also analyze the impact of a liquidity coverage ratio payout restrictions and a leverage ratio on the bank s financing choices and show that all these tools are able to curb the bank s reliance on repos

cash holdings and credit risk intuition suggests that rms with higher cash holdings are safer and should have lower credit spreads yet empirically the correlation between cash and spreads is robustly positive and higher for lower credit ratings this puzzling nding can be explained by the precautionary motive for saving cash in our model endogenously determined optimal cash reserves are positively related to credit risk resulting in a spurious positive correlation between cash and spreads by contrast spreads are negatively related to the exogenous component of cash holdings independent of credit risk factors similarly although rms with higher cash reserves are less likely to default over short horizons longer term endogenously determined liquidity may be positively related to the probability of default our empirical analysis conrms these predictions suggesting that endogenous precautionary savings are central to understanding the eects of cash on credit risk

a stochastic frontier approach to modelling financial constraints in firms an application to india we propose the use of stochastic frontier approach to modelling financial constraints of firms the main advantage of the stochastic frontier approach over the stylised approaches that use pooled ols or fixed effects panel regression models is that we can not only decide whether or not the average firm is financially constrained but also estimate a measure of the degree of the constraint for each firm and for each time period and also the marginal impact of firm characteristics on this measure we then apply the stochastic frontier approach to a panel of indian manufacturing firms for the 1997 2006 period in our application we highlight and discuss the aforementioned advantages while also demonstrating that the stochastic frontier approach generates regression estimates that are consistent with the stylised intuition found in the literature on financial constraint and the wider literature on the indian credit capital market

robustly strategic consumption portfolio rules with informational frictions this paper provides a tractable continuous time constant absolute risk aversion gaussian framework to explore how the interactions of fundamental uncertainty model uncertainty due to a preference for robustness and state uncertainty due to information processing constraints rational inattention affect strategic consumption portfolio rules and precautionary savings in the presence of uninsurable labor income specifically after solving the model explicitly i compute and compare the elasticities of strategic asset allocation and precautionary savings to risk aversion robustness and inattention furthermore for plausibly estimated and calibrated model parameters i quantitatively analyze how the interactions of model uncertainty and state uncertainty affect the optimal share invested in the risky asset and show that they can provide a potential explanation for the observed stockholding behavior of households with different education and income levels this paper was accepted by neng wang finance

the sensitivity of consumption to transitory income estimates from panel data on households we investigate the stochastic relation between income and consumption specifically consumption of food within a panel of about 2 000 households our major findings are 1 consumption responds much more strongly to permanent than to transitory movements of income 2 the response to transitory income is nonetheless clearly positive 3 a simple test independent of our model of consumption rejects a central implication of the pure life cycle permanent income hypothesis the observed covariation of income and consumption is compatible with pure life cycle permanent income behavior on the part of80 percent of families and simple proportionality of consumption and income among the remaining 20 percent as a general matter our findings support the view that families respond differently to different sources of income variations in particular temporary income tax policies have smaller effects on consumption than do other more permanent changes in income of the same magnitude this abstract was borrowed from another version of this item

consumption puzzles and precautionary savings abstract when marginal utility is convex agents accumulate savings as a precautionary measure against labor income eventualities this paper shows that precautionary savings can go a long way in making the excess growth excess smoothness and excess sensitivity features of consumption consistent with the stochastic processes of labor income observed in the u s at the microeconomic level

liquidation fire sales and acquirers private information abstract we develop a dynamic model in which a distressed firm optimizes an exit choice between sell out and default as well as its timing we assume that the distressed firm is not informed about the acquirer s asset valuation we show that the firm delays liquidation to decrease the acquirer s information rent notably the firm can change the exit choice from sell out to default when the screening cost is high in this case shareholders declare default regardless of the acquirer s valuation which provides the acquirer the maximum information rent together with the deadweight costs of bankruptcy the maximal information rent which causes a wealth transfer from debt holders of the bankrupt firm to the acquirer lowers the sales price and debt recovery this mechanism can explain many empirical findings about fire sales and acquirers excess gains higher volatility leverage and asymmetric information increase the likelihood of a fire sale but higher bankruptcy costs could play a positive role in preventing a fire sale with asymmetric information the firm can reduce debt issuance to avoid the risk of a fire sale

optimal debt and equity values in the presence of chapter 7 and chapter 11 explicit presence of reorganization in addition to liquidation leads to conflicts of interest between borrowers and lenders in the first best outcome reorganization adds value to both parties via higher debt capacity lower credit spreads and improved overall firm value if control of the ex ante reorganization timing and the ex post decision to liquidate is given to borrowers most of the benefits are appropriated by borrowers ex post lenders can restore the first best outcome by seizing this control or by the ex post transfer of control rights reorganization is more likely and liquidation is less likely relative to the benchmark case with liquidation only the u s bankruptcy code which includes a liquidation process chapter 7 and a reorganization process chapter 11 aims to resolve a number of important issues associated with a distressed firm these issues can be classified into information asymmetry problems e g quality of the firm heinkel and zechner 1993 agency problems e g risk shifting jensen and meckling 1976 or coordination problems e g debt of various maturities berglof and von thadden 1994 in this paper we investigate whether there is a place for a reorganization process in the presence of costly financial distress and liquidation these costs capture in reduced form the aforementioned frictions we wish to characterize the states of a borrowing firm relative to its outstanding contractual debt obligations at different stages of financial distress assuming full information and a single issue of debt we also seek to determine the role played by the bankruptcy code in improving the welfare of borrowers and lenders and how its influence depends on the rights given to borrowers and lenders at various stages of financial distress more precisely we build on structural models of debt merton 1974 black and cox 1976 which allows us to determine overall firm value along with the values of equity and debt in line with this literature we assume that liquidation destroys part of the firm s value we then ask the basic and yet important

the corporate propensity to save why do corporations accumulate liquid assets we show theoretically that intertemporal trade offs between interest income taxation and the cost of external finance determine optimal savings intriguingly we find that controlling for tobin s q saving and cash flow are negatively related because firms lower cash reserves to invest after receiving positive cash flow shocks and vice versa consistent with theory we estimate negative propensities to save out of cash flow we also find that income uncertainty affects saving more than do external finance constraints therefore contrary to previous evidence saving propensities reflect too many forces to be used to measure external finance constraints

utility based estimation of labour supply functions in the regular and irregular sectors recent theoretical work on labor supply has shown that the tax and transfer system can induce some individuals to work in the irregular labor market models designed to represent such behavior are unable to sign unambiguously the impact of the marginal tax rate as well as many key exogenous parameters on the hours supplied in the irregular market except under strong restrictions on preferences in this paper the authors estimate a simultaneous labor supply model that allows testing some of the more common assumptions found in the literature using a unique data set on the underground economy of the metropolitan area of quebec city canada estimates of elasticities with respect to predetermined variables are presented moreover they test and empirically reject the assumptions of perfect substitution between regular and irregular work activities as well as additive separability of the utility function copyright 1992 by royal economic society

debt valuation renegotiation and optimal dividend policy the valuation of debt and equity reorganization boundaries and firm s optimal dividend policies are studied in a framework where we model strategic interactions between debt holders and equity holders in a game theoretic setting which can accommodate varying bargaining powers to the two claimants two formulations of reorganization are presented debt equity swaps and strategic debt service resulting from negotiated debt service reductions we study the effects of bond covenants on payout policies and distinguish liquidity induced defaults from strategic defaults we derive optimal equity issuance and payout policies the debt capacity of the firm and the optimal capital structure are characterized

foreign investment and ethics how to contribute to social responsibility by doing business in less developed countries do foreign direct investment fdi and international business ventures promote positive social and economic development in emerging nations this question will always prove contentious first the impacts differ according to context second the social consequences and spillover effects of knowledge diffusion and technology sharing may be limited and hard to measure third contributions to enhancing social responsibility and improving living standards in host countries are delayed in effect causally complex and also hard to measure outcomes often critically depend on collaboration of governments international institutions the business world and non governmental organizations ngos research in this area is challenging and requires interdisciplinary collaboration between economists financial experts sociologists ethicists and other specialists this paper explores 1 the evidence to support the proposition that fdi and international business improve social conditions in less developed countries and 2 how these improvements are linked to strategies of corporate social responsibility csr and ethical business practice the paper draws insights from development fdi poverty alleviation and bottom of the pyramid bop literature applications are demonstrated using examples from poverty stricken areas of sub saharan africa the paper attempts not only to argue theoretically but also to provide practical evidence the approach is simultaneously descriptive analytical and prescriptive in order to address a wide audience it also highlights issues and trends for further academic research and presents the viewpoint that some limitations lie in the nature of ethics frameworks widely referenced in business and that these often fail to consider the compatibility of ethical constructs with relevant incentives in this vein we explore the application of homann s framework for advantage and incentive based ethics

term structures of credit spreads with incomplete accounting information we study the implications of imperfect information for term structures of credit spreads on corporate bonds we suppose that bond investors cannot observe the issuer s assets directly and receive instead only periodic and imperfect accounting reports for a setting in which the assets of the firm are a geometric brownian motion until informed equityholders optimally liquidate we derive the conditional distribution of the assets given accounting data and survivorship contrary to the perfect information case there exists a default arrival intensity process that intensity is calculated in terms of the conditional distribution of assets credit yield spreads are characterized in terms of accounting information generalizations are provided

an investigation of ricardian equivalence in a common trends model abstract to empirically discriminate between ricardian and non ricardian behaviour we have to use a method that distinguishes between expected and unexpected as well as permanent and transitory changes in taxes and government consumption one method that provides these distinctions between different types of changes is the common trends framework used in this paper which is a var model with cointegrating constraints in the empirical study of us data there is some support for the ricardian hypothesis but there are also some deviations from its predictions however the differences do not lend support to a keynesian view of budget deficits but rather to the view of expansionary fiscal contractions this can be motivated theoretically by uncertainty about future taxes in combination with prudent households

perspectives on positive political economy this volume serves as an introduction to the field of positive political economy and the economic and political processes with which it is concerned this new research tradition is distinct from both normative and historical approaches to political economy grounded in the rational actor methodology of microeconomics positive political economy is the study of rational decisions in a context of political and economic institutions more analytical than traditional approaches it is concerned with the derivation of principles and propositions against which real world experience may be compared its focus is on empirical regularities and its goal is theoretical explanation the field has focused on three main areas of research models of collective action constraints on competitive market processes and the analysis of transaction costs developments in all of these areas are covered in the book the first part of the volume surveys the field while the second part displays positive political economy at work examining a variety of subjects the final part contains essays by leading political economists on the theoretical foundations of the field

corporate policies with permanent and transitory shocks we model the financing cash holdings and hedging policies of a firm facing financing frictions and subject to permanent and transitory cash flow shocks the permanent and transitory shocks generate distinct sometimes opposite effects on corporate policies we use the model to develop a rich set of empirical predictions in our model correlated permanent and transitory shocks imply less risk lower cash savings and a drop in the value of credit lines the composition of cash flow shocks affects the cash flow sensitivity of cash which can be positive or negative optimal hedging of permanent and transitory shocks may involve opposite positions

idiosyncratic production risk growth and the business cycle we introduce a neoclassical growth economy with idiosyncratic production risk and incomplete markets each agent is an entrepreneur operating her own technology with her own capital stock the general equilibrium is characterized by a closed form recursion in the cara normal case incomplete markets introduce a risk premium on private equity which reduces the demand for investment as compared to complete markets the steady state can thus have both a lower capital stock due to investment risk and a lower interest rate due to precautionary savings furthermore the anticipation of high real interest rates in the future feeds back into high risk premia and low investment in the present thus slowing down convergence to the steady state our results highlight the importance of private risk premia for capital accumulation and business cycles

cyclical uncertainty precautionary saving and economic growth this paper studies the interaction between cyclical uncertainty precautionary saving and economic growth in a stochastic endogenous growth model the analysis provides insight into the potential connection between technological uncertainty of the sort popularized in real business cycle models and the determinants of economic growth in a stochastic version of a popular model of endogenously determined economic growth the magnitude of the link between cyclical uncertainty and growth is quantified and found to be small in terms of its effect on the growth rate but possibly large in terms of its effect on levels of macroeconomic variables moreover the welfare costs of reduced cyclical uncertainty can be substantial owing to the lower historical rate of capital accumulation induced by a decrease in precautionary saving the chief implications of the model are found to be roughly consistent with the postwar experience of several countries although the predictions of the model with regard to growth rates are too small to explain much of the variation in growth rates across time or across countries

study on labour supply when tax evasion is an option with box cox functional forms and random parameters labour supply when tax evasion is an option is analysed within a discrete choice framework which incorporates random parameters and box cox functional forms using mixed logit models deviates in parameters and in some cases correlation between alternatives in the evasion group are found to be significant the models utilized yield good predictions in terms of labour supply and taxes paid by nonevaders the goodness of fit and quality of prediction is improved by the introduction of correlation between random coefficients

the autonomy of the contracting partners an argument for heuristic contractarian business ethics due to the domain characteristics of business ethics a contractarian theory for business ethics will need to be essentially different from the contract model as it is applied to other domains much of the current criticism of contractarian business ethics cbe can be traced back to autonomy one of its three boundary conditions after explaining why autonomy is so important this article considers the notion carefully vis a vis the contracting partners in the contractarian approaches in business ethics autonomy is too demanding a condition for the realm of cbe but a less stringent version of the contract may be possible a version which uses the contract as a heuristic device which merely requires moral responsibility furthermore it is argued that views of human agency and the moral subject should be made explicit in such a theory

the deaton paradox in a long memory context with structural breaks this article contributes to the permanent income hypothesis pih and excess consumption smoothness debate in the context of fractional integration we show that the excess consumption smoothness result is a consequence of the quarterly data frequency commonly employed in the empirical work in fact the i 1 hypothesis is rejected for the income process with monthly data in favour of a fractional integration order lower than 1 moreover if a structural break is taken into account we observe a substantial reduction in the degree of consumption smoothness especially after the break found in 1975

precautionary saving in the small and in the large the theory of precautionary saving is shown to be isomorphic to the arrow pratt theory of risk aversion making possible the application of a large body of knowledge about risk aversion to precautionary saving and more generally to the theory of optimal choice under risk in particular a measure of the strength of the precautionary saving motive analogous to the arrow pratt measure of risk aversion is used to establish a number of new propositions about precautionary saving and to give a new interpretation of the dreze modigliani substitution effect copyright 1990 by the econometric society

tax evasion and occupational choice this paper is concerned with the combined effect of tax compliance and tax audit policy on the occupational choice of individuals and on public policy objectives such as tax revenue total production and social welfare individuals are assumed to have a choice between riskless work and a risky entrepreneurial occupation they are only differentiated according to their attitudes towards risk more risk averse individuals go into the safe occupation and less risk averse people become entrepreneurs tax evasion is only accessible to the latter and therefore its control tends to discourage risk taking whether control of tax evasion is desirable for the economy as a whole depends on the objective function of the government it is shown that tax audit policy has conflicting effects on tax revenue per capita income and social welfare these conflicts are illustrated through a numerical example in this paper the emphasis is placed on the clarity and the simplicity of the presentation so as to argue that even though the tax schedule can hardly be differentiated across individuals tax evasion and its control can be used by policymakers to introduce variability in the individual s tax treatment
