This article studies a model of consumption, savings, and job search in which a borrowing constraint limits self‐insurance. The government administers the unemployment insurance program that may condition on an individual’s asset position, but not on her efforts of finding a job. To compensate for the impediments to self‐insurance, benefit payments should optimally be set higher at lower wealth levels and peak for borrowing‐constrained individuals with zero liquid funds. A quantitative exercise reveals that the U.S. unemployment insurance program is surprisingly close to optimal for the asset poor, but far too generous for wealthier individuals.  相似文献

This paper examines aggregate savings in a general equilibrium model where infinitely lived households face volatile (and possibly uncertain) income paths, hold a risk-free asset, and face a borrowing constraint. I first show that the equilibrium capital stock in an economy without uncertainty, but where individual income varies, can be larger than in an economy where each household's income is constant. When individual income is stochastic and uninsurable, the equilibrium capital stock is always larger than when income is constant. This additional capital accumulation has sometimes been interpreted as precautionary savings, but I argue that much of the additional savings are generated by permanent-income motives in combination with strict borrowing constraints.  相似文献

This paper tests how subjects behave in an intertemporal consumption/saving experiment when borrowing is allowed and whether subjects treat debt differently than savings. Two treatments create environments where either saving or borrowing is required for optimal consumption. Since both treatments share the same optimal consumption levels, observed consumption choices can be directly compared across treatments. The experimental findings imply that deviations from optimal behavior are higher when subjects have to borrow than when they have to save in order to consume optimally, suggesting debt aversion. Signifiant under-consumption is observed when subjects have to borrow in order to reach optimal consumption. In line with previous experiments, weak evidence is found suggesting that subjects over-consume when saving is necessary for optimal consumption.  相似文献

The recent literature has shown that income inequality is one of the main causes of borrowing and debt accumulation by working households. This article explores the possibility that household indebtedness is an important cause of rising income inequality. If workers experience rising debt burdens, their cost of job loss may rise if they need labor-market income to continue borrowing and servicing existing debt. This, in turn, will reduce their bargaining power and increase income inequality, inducing workers to borrow more to maintain consumption standards, and so creating a vicious circle of rising inequality, job insecurity, and indebtedness. We believe that these dynamics may have contributed to observed simultaneous increases in income inequality and household debt prior to the recent financial crisis. To explore the two-way interaction between inequality and debt, we develop an employment rent framework that explicitly considers the impact of workers’ indebtedness on their perceived cost of job loss. This is embedded in a neo-Kaleckian macro model in which inequality spurs debt accumulation that contributes to household consumption spending and hence demand formation. Our analysis suggests that (a) workers’ borrowing behavior plays a crucial role in understanding the character of demand and growth regimes; (b) debt and workers’ borrowing behavior play an important role in the labor market by influencing workers’ bargaining power; and (c) through such channels, workers’ borrowing behavior can be a decisive factor in the determination of macroeconomic (in)stability.  相似文献

The odious debt problem refers to a government's ability to borrow for elite consumption while the general population repays. Although an intuitive response is to ban lending to such regimes, this paper shows that if a government faces endogenous replacement risk, then an international odious debt doctrine which (i) decreases the country's debt ceiling; (ii) decreases the likelihood that the citizens must repay the debt; or (iii) increases the government's cost of borrowing for a given default risk can all decrease citizens' welfare. These findings suggest that, even when a regime is clearly odious, allowing it to borrow up to a point may be preferable to a complete lending ban.  相似文献

Empirical evidence suggests that real exchange rates (RER) behave differently in developed and developing countries. We develop an overlapping generations two-sector exogenous growth model in which RER determination may depend on the country's capacity to borrow from international capital markets. The country faces a constraint on capital inflows. With high domestic savings, the RER only depends on the productivity spread between sectors (Balassa–Samuelson effect). If the constraint is too tight and/or domestic savings too low, the RER depends on both net foreign assets (transfer effect) and productivity. We then analyze the empirical implications of the model and find that, in accordance with the theory, the RER is mainly driven by productivity and net foreign assets in constrained countries and by productivity in unconstrained countries.  相似文献

This article examines how financial constraints affect redistribution via monetary policy. We explore a novel mechanism of monetary nonneutrality, which is based on debt limits imposed in nominal terms. Specifically, when debt is constrained by current income, monetary policy can alter the real terms of borrowing. Changes in inflation exert ambiguous effects, depending on the initial debt/wealth position and the willingness to borrow. We show analytically that borrowers can benefit from increased debt limits under lower inflation rates. This novel effect can dominate conventional debt deflation effects. We find that particularly less indebted borrowers as well as potential future borrowers gain and that aggregate welfare can be enhanced under a permanent reduction in inflation.  相似文献

The objective of this paper is to investigate the effect of lending and borrowing constraints on the dynamics of public debt and optimal taxation policy in the context of a general equilibrium model with tax smoothing. The results from the numerical simulation of the model show significant welfare gains, provided that the policymaker is allowed to borrow and lend in order to smooth taxes across time instead of maintaining a balanced budget at all times. Moreover, for a specific process for asset prices, it is also shown that if the government can issue state-contingent debt then overall welfare can be further improved substantially.  相似文献

When future human capital cannot be alienated, households are allowed to borrow up to the point where it is in their own interest not to default. In such a framework, endogenous borrowing limits arise as the outcome of individual rationality constraint. In a model where education is the engine of growth, we show that endogenous borrowing constraints imply global indeterminacy. Comparing outcomes across the various equilibria we show that the relation between growth and yields is hump-shaped. Maximum growth can arise in an equilibrium with binding borrowing constraints, specially if the elasticity of human capital to education spending is large. Deepening financial markets promotes long-run growth in the case of a poverty trap, but not necessarily otherwise. On the methodological side, our approach stresses the importance of studying borrowing limits in general equilibrium, not only in small open economies. Philippe Michel passed away on July 22, 2004. His death is a great loss for his friends and for the overlapping generations and optimal control community.  相似文献

This paper quantifies the effects of precautionary savings. It demonstrates that Zeldes' estimate of excess consumption growth for low asset holders is consistent with a dynamic general equilibrium model with uninsurable endowment shocks when borrowing is constrained at three months' worth of average wage income. I propose a Monte Carlo simulation of the stationary equilibrium as a method of indirectly testing the hypotheses of a no-borrowing specification and a natural debt limit specification. At the estimated borrowing constraint, an increase in endowment shocks within the range of empirical findings can cause a 1.6% increase in the savings rate and a 6.9% increase in capital.  相似文献

本文借用两个相关的模型探讨流动性约束和政府消费替代对于我国居民消费过度波动现象的解释力,发现流动性约束和政府消费分别通过弱化居民消费跨期优化能力和增强其对居民消费替代作用的渠道来增加居民消费波动,且前者的作用强于后者。本文同时发现流动性约束的增加减损居民福利,而政府消费替代比例的增加则能提高居民福利。  相似文献

本文利用中国家庭金融调查(CHFS)2011年度的调查数据,考察了收入不平等对家庭借贷行为的影响,并验证了家庭是否存在为追求社会地位而借贷的动机。研究表明:(1)收入不平等并不是影响家庭是否借贷的主要因素,但是对家庭的负债规模存在十分显著的抑制作用;(2)收入不平等的扩大并不会促使中低收入家庭寻求借贷或提升家庭负债规模,我国家庭并不存在为了追求更高的社会地位而进行借贷的动机;(3)收入不平等的扩大有利于高收入家庭获得更多的正规金融借贷,中低收入家庭则会较多地依赖于非正规金融借贷;(4)户主的人口统计学特征、家庭经济特征以及家庭所处地区特征均是影响家庭借贷行为的重要因素,在正规金融和非正规金融市场上,影响家庭借贷行为的因素存在较明显的差异。  相似文献

This paper presents a two‐sector, two‐country model showing that inflation in the housing market, a low personal savings rate, and a construction investment boom can contribute to a large current account deficit. In the model, demand by a group of households in the domestic country is constrained by the availability of collateral. This implies more procyclical debt capacity because constrained households can borrow against the increase in the value of their houses during an expansion. A higher degree of financial liberalization and development helps constrained households reach higher loan‐to‐value ratios, thus relaxing their borrowing constraints. The resulting higher net worth and lower need for savings imply a worsening current account.  相似文献

We incorporate home production in a dynamic general equilibrium model of consumption and savings with illiquid housing and a collateralized borrowing constraint. The calibrated model explains life‐cycle patterns of households' time use and consumption of different categories documented from the microdata. It predicts that the interaction of the labor efficiency profile and the home production technology explains households' time use. The resulting income profiles, the endogenous borrowing constraint, and home production account for the initial hump in consumption. The complementarity of home hours, home input, and housing in home production drives the consumption profiles later in the life cycle.  相似文献

This study considers the politics of public education and its impact on economic growth and welfare across generations. We employ probabilistic voting to demonstrate the generational conflict regarding taxes and spending and show that aging shifts the tax burden from the retired to the working generation, reduces public education spending, and ultimately slows economic growth. We subsequently consider a legal constraint that aims to boost education spending: a spending floor for education. This constraint stimulates economic growth but creates a trade-off between current and future generations’ welfare. Finally, the quantitative implications of our results are explored by calibrating the model to the Japanese economy.  相似文献

How does a country's exchange rate regime impact its ability to borrow from abroad? We build a small open economy model in which the government responds to shocks by adjusting monetary policy and foreign borrowing. Sovereign borrowing is subject to endogenous limits, which ensure repayment when the default punishment corresponds to financial autarky. Dollarizing implies renouncing monetary policy, but can make access to international debt markets more valuable, thereby loosening borrowing constraints. This mechanism linking dollarization to financial integration is consistent with observed declines in spreads on foreign-currency debt in countries adopting the dollar or the euro.  相似文献

The paper uses data from Armenia to test the implications of remittance flows on behavior of receiving households. We find that remittance‐receiving households work fewer hours and spend less on the education of their children. While saving more, these households are not leveraging their savings to borrow from the banking system to expand their business activities. This evidence suggests that the benefits of remittances might be overstated and emphasizes the importance of measuring their impact in a general‐ rather than a partial‐equilibrium context.  相似文献

This paper argues that output volatility depends on the degree of credit market imperfection. In the early stages of financial development, agents are constrained in their borrowing ability. As a result, the individual savings, affected by the labor supply, play a dual role in the economy, having repercussions on the interest rate. On the one hand, high savings imply high investment, low marginal product of capital and thus low interest rate. On the other hand, high savings affect the agents' ability to run highly productive investment projects, which increases the interest rate. When the former effect is dominant, a dynamic complementarity between individual and aggregate labor supply arises. This leads to a local and global indeterminacy of equilibrium paths. If the borrowing constraint is relaxed, the complementarity between individual and aggregate labor supply decisions weakens, equilibrium becomes globally unique and the possibility of having aggregate fluctuations in output disappears.  相似文献

This paper analyzes the welfare effects of unemployment insurance reforms in a general equilibrium incomplete market model. In particular, it decomposes the total welfare effect for each individual into different factors. I consider a model where the consumers face an uninsurable unemployment risk, can save in an interest-bearing asset, and are subject to a borrowing constraint. The labor market is modeled using a Diamond–Mortensen–Pissarides style search and matching model. The decomposition exercises reveal how each factor contributes to the heterogeneity of welfare effects among different consumers.  相似文献
