labor unemployment risk and corporate financing decisions this paper examines the impact of labor unemployment risk on corporate financing decisions theory suggests that firms choose conservative financial policies partly as a means of mitigating worker exposure to unemployment risk using changes in state unemployment insurance benefit laws as a source of variation in the costs borne by workers during layoff spells we explore the connection between unemployment risk and the corporate financing decisions of public firms in the united states we find that increases in legally mandated unemployment benefits lead to increases in corporate leverage the impact of reduced unemployment risk on financial policy is especially strong for firms that have greater layoff separation rates labor intensity and financing constraints the estimated premium required to compensate workers for unemployment risk due to financial distress is about 57 basis points of firm value for a bbb rated firm these findings suggest that labor market frictions have a significant impact on corporate financing decisions

standard risk aversion this paper introduces the concept of standard risk aversion a von neumann morgenstern utility function has standard risk aversion if any risk makes a small reduction in wealth more painful in the sense of an increased reduction in expected utility also makes any undesirable independent risk more painful it is shown that given monotonicity and concavity the combination of decreasing absolute risk aversion and decreasing absolute prudence is necessary and sufficient for standard risk aversion standard risk aversion is shown to imply not only pratt and zeckhauser s proper risk aversion individually undesirable independent risks always being jointly undesirable but also that being forced to face an undesirable risk reduces the optimal investment in a risky security with and independent return similar results are established for the effect of broad class of increases in one risk on the desirability of or optimal investment in a second independent risk

overcoming institutional voids via arbitration extending the literature on institutional voids we introduce theory from law that highlights the ability of firms to choose the laws and enforcement mechanisms that govern their international joint ventures ijvs specifically firms may overcome institutional voids by borrowing institutions via binding international commercial arbitration bica rather than relying on host market institutions leveraging an institution based view we develop a theoretical framework to articulate the conditions under which ijv partners may choose bica as opposed to domestic courts to overcome institutional voids in host markets

dusenberry s ratcheting of consumption optimal dynamic consumption and investment given intolerance for any decline in standard of living duesenberry s ratcheting consumption demand is derived as a feature of the optimal dynamic consumption and investment policy given extreme habit formation that prevents consumption from falling over time preferences are in effect non time separable extended real valued von neumann morgenstern preferences consumption increases each time wealth reaches a new maximum risky investment is proportional to the excess of wealth over the perpetuity value of current consumption extensions constrain the net rate of decrease in consumption with a constant other than zero add more consumption goods and constrain on the maximal holding of the risky asset as a proportion of wealth these strategies may be useful for the management of university endowments participatory investment accounts and risky arbitrage funds

efficiency and equity in the producer levy of india india s producer levy scheme has been considered a prime example of government market intervention to depress price incentives for farm producers analysis in this study shows that the scheme increases the average producer price for the short run with inelastic supply in this case significant improvements in income distribution can be obtained with little loss of economic efficiency if the scheme is implemented effectively however if the scheme is applied for the long run it might result in market instability more critically the scheme is likely to have an adverse effect on income distribution in the absence of effective implementation

the subsidization of farming households in china s agriculture concerned about national food self sufficiency and rural household incomes in 2004 china decided to reverse its longstanding policy of taxing farm households and instead began to provide them with subsidies since 2004 annual announcements have trumpeted rises in subsidies despite the historic turnaround of policy and likely implication of this subsidy policy to china s food economy there has been little household level survey based research that has sought to understand the nature of china s subsidy programs from the viewpoint of the farmer using data from two sets of household based surveys covering tens of thousands of households and most major producing provinces and survey data from government in this paper we examine the subsidies that are directly given to farmers one of the newest and relatively high profiles components of china s subsidy programs we focus on china s grain input seed and machinery subsidy programs according to the survey based findings we show that although agricultural subsidies per farm are low on a per hectare basis the rate of subsidies is high almost all producers are receiving them subsidies are mostly being given to the land contractor not the tiller most of grain input and seed subsidies are non distorting but machinery subsidy is based on farmers actual purchase of machineries

effects of agricultural market policy on crop production in china this paper investigates the effects of chinese market policy on crop production in the reform process after a brief review of the policy changes due to the reform the theoretical significance of chinese market policies for crop production is demonstrated diagrammatically it is shown that under the current market system the production of main crops is significantly influenced by both market and quota prices while relatively high quota reduces the influence of market prices on production relative price changes between competing crops will lead to shifting farmers cultivation preferences if inputs are constant empirical analysis based on cross section data for the period 1985 1997 from the province of zhejiang confirms these hypotheses the effects of policy variables however prove to be crop specific if the potential of crop production in china is to be better used an even more market oriented agricultural policy is required

life cycle portfolio choice with additive habit formation preferences and uninsurable labor income risk this article explores the implications of additive and endogenous habit formation preferences in the context of a life cycle model of an investor who has stochastic uninsurable labor income to solve the model i analytically derive the habit wealth feasibility constraints and show that they depend on the worst possible path of future labor income and on the habit strength but not on the probability of the worst income when there is only a slim chance of a severe income shock the model implies much more conservative portfolios the model also predicts that for some low to moderately wealthy households the portfolio share allocated to stocks increases with wealth because of this feature the model can generate more conservative portfolios for younger than for middle aged households the effects of habits on portfolio choice are robust to income smoothing through borrowing or flexible labor supply one controversial finding is that for high values of the habit strength parameter usually required for the resolution of asset pricing puzzles in general equilibrium the life cycle model predicts counterfactually high wealth accumulation jel g11 g12 copyright 2007 oxford university press

historical antisemitism ethnic specialization and financial development historically european jews have specialized in financial services while being the victims of antisemitism we find that the present day demand for finance is lower in german counties where historical antisemitism was higher compared to otherwise similar counties households in counties with high historical antisemitism have similar saving rates but invest less in stocks hold lower saving deposits and are less likely to get a mortgage to finance homeownership after controlling for wealth and a rich set of current and historical covariates present day antisemitism and supply side forces do not fully explain the results households in counties where historical antisemitism was higher distrust the financial sector more a potential cultural externality of historical antisemitism that reduces wealth accumulation in the long run

a theory of the consumption function with and without liquidity constraints fifteen years ago milton friedman s 1957 treatise a theory of the consumption function seemed badly dated dynamic optimization theory had not been employed much in economics when friedman wrote and utility theory was still comparatively primitive so his statement of the permanent income hypothesis never actually specified a formal mathematical model of behavior derived explicitly from utility maximization instead friedman relied at crucial points on intuition and verbal descriptions of behavior although these descriptions sounded plausible when other economists subsequently found multiperiod maximizing models that could be solved explicitly the implications of those models differed sharply from friedman s intuitive description of his model furthermore empirical tests in the 1970s and 1980s often rejected these rigorous versions of the permanent income hypothesis in favor of an alternative hypothesis that many households simply spent all of their current income today with the benefit of a further round of mathematical and computational advances friedman s 1957 original analysis looks more prescient than primitive it turns out that when there is meaningful uncertainty in future labor income the optimal behavior of moderately impatient consumers is much better described by friedman s original statement of the permanent income hypothesis than by the later explicit maximizing versions furthermore in a remarkable irony much of the empirical evidence that rejected the permanent income hypothesis as specified in tests of the 1970s and 1980s is actually consistent both with friedman s original description of the model and with the new version with serious uncertainty there are four key differences between the explicit maximizing models

social interaction and stock market participation we propose that stock market participation is influenced by social interaction in our model any given social investor finds the market more attractive when more of his peers participate we test this theory using data from the health and retirement study and find that social households those who interact with their neighbors or attend church are substantially more likely to invest in the market than non social households controlling for wealth race education and risk tolerance moreover consistent with a peer effects story the impact of sociability is stronger in states where stock market participation rates are higher

plan and market in china s agricultural commerce this article examines interactions between markets and state commercial planning in the context of china s agricultural sector it begins with a discussion of recent trends in agricultural planning and commerce in china and then presents a theoretical model that analyzes the way that a mixed commercial system of the sort observed in china functions the theoretical analysis suggests that a mixed system is sustainable and can have desirable efficiency and distributional effects markets however limit the range of sustainable plans and in the presence of markets state planning may no longer directly influence production and consumption behavior

distributional consequences of rural food levy and subsidized urban rations abstract governments in many developing countries have imposed food levies on farmers to provide subsidized food to urban consumers the resulting price discrimination between individuals has general equilibrium effects so that the welfare consequences of such a policy for different socio economic groups have been controversial we relate the distributional consequences to the parameters of the economy and identify systematic relationships among different partitions of the outcomes we show for instance that if the policy helps hurts richer city dwellers then it hurts helps poorer farmers

moral hazard vs liquidity and optimal unemployment insurance this paper presents new evidence on why unemployment insurance ui benefits affect search behavior and develops a simple method of calculating the welfare gains from ui using this evidence i show that 60 percent of the increase in unemployment durations caused by ui benefits is due to a liquidity effect rather than distortions on marginal incentives to search moral hazard by combining two empirical strategies first i find that increases in benefits have much larger effects on durations for liquidity constrained households second lump sum severance payments increase durations substantially among constrained households i derive a formula for the optimal benefit level that depends only on the reduced form liquidity and moral hazard elasticities the formula implies that the optimal ui benefit level exceeds 50 percent of the wage the exact identification approach to welfare analysis proposed here yields robust optimal policy results because it does not require structural estimation of primitives

a news utility theory for inattention and delegation in portfolio choice recent evidence suggests that investors are inattentive to their portfolios and hire expensive portfolio managers this paper develops a life cycle portfolio choice model in which the investor experiences loss averse utility over news and can ignore his portfolio in such a model the investor prefers to ignore and not rebalance his portfolio most of the time because he dislikes bad news more than he likes good news such that expected news causes a first order decrease in utility consequently the investor has a first order willingness to pay a portfolio manager who rebalances actively on his behalf moreover the investor can diversify over time and his consumption aligns with predictions of mental accounting i structurally estimate the preference parameters by matching stock shares and stock market non participation over the life cycle my parameter estimates are in line with the literature generate reasonable intervals of inattention and simultaneously explain consumption and wealth accumulation over the life cycle here it matters that news utility preserves first order risk aversion even in the presence of stochastic labor income which also causes stock shares to rise in wealth

grain policy in chinese villages yield response to pricing procurement and loan policies this paper assesses the effects of pricing procurement and loan policies on china s grain economy a dynamic control model of the village leader is specified parameters of structural and control equations are estimated using time series cross section data simulation results show that pricing and procurement policies are not effective in raising yields because of conflicting objectives of local officials loan policies can increase yields the paper concludes that rural policies often have contradictory effects that can arise for a number of reasons an important reason is the fact that local officials in a reforming economy have greater decision making discretion than higher level officials and execute policies to meet their own objectives

a new database on the structure and development of the financial sector this article introduces a new database of indicators of financial structure and financial development across countries and over time the database is unique in that it combines a wide variety of indicators that measure the size activity and efficiency of financial intermediaries and markets it improves on previous efforts by presenting data on the public share of commercial banks introducing indicators of the size and activity of nonbank financial institutions and constructing measures of the size of bond and primary equity markets this article introduces a new database the first to provide comprehensive measures of the development structure and performance of the financial sector this database is the first to define and construct indicators of the size and activity of nonbank financial intermediaries such as insurance companies pension funds and non deposit money banks it is also the first to include indicators of the size of primary equity markets and primary and secondary bond markets in constructing the database authors carefully deflate measures and match stock and flow variables

income risk borrowing constraints and portfolio choice economic theory suggests that uninsurable income risk and the expectation of future borrowing constraints can reduce the share of risky assets in a household s portfolio if the utility function exhibits decreasing absolute risk aversion and decreasing prudence an individual will reduce his exposure to rate of return risks when confronted with other independent risks if there are transaction costs the expectation of future borrowing constraints should induce individuals to keep a lower proportion of their wealth in the form of illiquid and risky assets the authors find support for these propositions in a cross section of italian households copyright 1996 by american economic association

national health insurance and precautionary saving evidence from taiwan abstract by reducing uncertainty about future medical expenses comprehensive health insurance can reduce households precautionary saving we examine this effect using taiwan micro data spanning the 1995 introduction of national health insurance the effects of national health insurance are identified using employment based variation in prior insurance coverage replacement of the households prior insurance coverage with national health insurance is exogenous to the household so our estimates are not subject to selection bias compared with the preceding government insurance programs national health insurance reduced saving by an average of 8 6 13 7 with the largest effects for households with the smallest saving

unemployment risks and optimal retirement in an incomplete market we develop a new approach for solving the optimal retirement problem for an individual with an unhedgeable income risk the income risk stems from a forced unemployment event which occurs as an exponentially distributed random shock the optimal retirement problem is to determine an individual s optimal consumption and investment behaviors and optimal retirement time simultaneously we introduce a new convex duality approach for reformulating the original retirement problem and provide an iterative numerical method to solve it reasonably calibrated parameters say that our model can give an explanation for lower consumption and risky investment behaviors of individuals and for relatively higher stock holdings of the poor we also analyze the sensitivity of an individual s optimal behavior in changing her wealth level investment opportunity and the magnitude of preference for postretirement leisure finally we find that our model explains a countercyclical pattern of the number of unemployed job leavers

health and other asset holdings despite clear evidence of correlations between financial and medical statuses and decisions most models treat financial and health related choices separately this article bridges this gap by proposing a tractable dynamic framework for the joint determination of optimal consumption portfolio holdings health investment and health insurance we solve for the optimal rules in closed form and capitalize on this tractability to gain a better understanding of the conditions under which separation between financial and health related decisions is sensible and of the pathways through which wealth and health determine allocations welfare and other variables of interest such as expected longevity or the value of health furthermore we show that the model is consistent with the observed patterns of individual allocations and provide realistic estimates of the parameters that confirm the relevance of all the main characteristics of the model

an option perspective on generating and maintaining plant variety rights in china notwithstanding the ambiguous research and productivity promoting effects of plant variety protections pvps even in developed countries many developing countries have adopted pvps in the past few years in part to comply with their trade related aspects of intellectual property rights trips obligations seeking and maintaining pvps reserves options to an expected revenue stream from the future sale of protected varieties the value of which varies for a host of reasons in this article we empirically examine the pattern of pvp applications in china since its pvp laws were first introduced in 1997 we place those pvp rights in the context of china s present and likely future seed markets to identify the economic incentives and institutional influences on decisions to develop and apply for varietal rights

oil price shocks and policy responses in the post reform chinese economy this study analyses the impact of the 1986 oil price shock on china and the policy options for accommodating the shock a computable general equilibrium model is used to capture the complex interactions in the chinese economy in response to the shock interpreted in the theoretical framework of the booming sector model the results of the model provide insights on both the real and monetary effects of the shock and suggest that a combination of policy instruments such as a cut in real absorption depreciation of the official exchange rate and tight monetary control are required to facilitate adjustment

why do so few hold stocks the authors investigate why 75 percent of u s households do not hold stocks despite the equity premium and predictions of expected utility models the question is relevant for privatization asset pricing and tax progressivity issues they show that risk aversion per se heterogeneity of beliefs habit persistence time nonseparability and quantity constraints on borrowing do not account for the phenomenon a wedge between borrowing and lending rates and minimum investment requirements are plausible but empirically weak factors more promising explanations are inertia and departures from expected utility maximization there is also qualified support for nondiversifiable income risk as a contributing factor copyright 1995 by royal economic society

unemployment insurance as a housing market stabilizer this paper studies the impact of unemployment insurance ui on the housing market exploiting heterogeneity in ui generosity across us states and over time we find that ui helps the unemployed avoid mortgage default we estimate that ui expansions during the great recession prevented more than 1 3 million foreclosures and insulated home values from labor market shocks the results suggest that policies that make mortgages more affordable can reduce foreclosures even when borrowers are severely underwater an optimal ui policy during housing downturns would weigh among other benefits and costs the deadweight losses avoided from preventing mortgage defaults

china s nutrient availability and sources 1950 1991 abstract the rapid changes in china s economy and data availability have led to the need for a quantitative assessment of its food and nutrient situation this paper first reports estimates of china s average per capita daily energy protein and fat availability through yearly food balance sheets for the period 1950 1991 then policy impacts on the nutrient changes are examined results suggest that china s nutritional status has improved significantly over the period especially since the 1978 economic reforms government policy has been a key factor influencing the nutrient changes since 1950 and will continue to play an important role in china s nutritional improvement

optimal retirement with unemployment risks abstract this paper investigates the optimal retirement of an individual in the presence of involuntary unemployment risks and borrowing constraints in a complete market with frictions we use an intensity model and loading factors to illustrate the involuntary unemployment risks and frictions in unemployment insurance markets using reasonably calibrated parameters we observe that high involuntary unemployment intensity and loading factors could be important explanations for the empirical findings emphasized in recent studies we also find that an individual with high leisure demand after retirement reduces consumption during retirement and increases stockholdings as retirement time approaches

control in a dynamic village economy the reforms and unbalanced development in china s rural economy abstract a dynamic control framework is used to model the chinese village economy in order to explain the rural sector s unbalanced growth in the post reform period village leaders are assumed to maximize a multi attribute utility function by manipulating local policy instruments subject to the structural relationships in the economy the model s parameters are estimated econometrically using a data set from forty villages in eastern china the empirical results identify important linkages between agriculture and rural industry in village economies unbalanced growth can partially be explained by the way economic incentives induce individuals in rural areas to move resources toward the rural industrial sector and away from agriculture

the wealth of the unemployed many studies have investigated the adequacy of unemployment insurance ui benefits as a form of income replacement but few have looked at other resources with which the unemployed can finance their unemployment spells this paper focuses on one form of resources own wealth holdings the author finds that the median worker s financial assets can cover roughly two thirds of the income loss from an unemployment spell wealth holdings vary tremendously however and almost one third of workers are unable to replace even 10 of their income loss moreover predicted wealth holdings decline precipitously with realized unemployment durations both absolutely and especially relative to actual income loss this finding together with the finding that individuals who are eligible for more generous ui draw down their wealth more slowly than do others during unemployment spells suggests that ui benefit adequacy could be increased if the benefits were targeted to those with longer unemployment spells

limited participation and consumption saving puzzles a simple explanation and the role of insurance in this paper we show that the existence of a large negative wealth shock and insufficient insurance against such a shock could explain both the limited stock market participation puzzle and the low consumption high savings puzzle we then conduct an empirical analysis on the relation between household portfolio choices and access to private insurance and various types of government safety nets the empirical results demonstrate that a lack of insurance against large negative wealth shocks is positively correlated with lower participation rates and higher saving rates overall the evidence suggests an important role of insurance in household investment and savings decisions
