The rise of female entrepreneurs: New evidence on gender differences in liquidity constraints

In this paper, we study the importance of liquidity constraints for entrepreneurial activity, using previously unexplored data from the UK. Using inheritances as an instrument, IV estimates reveal that single women drive the overall relationship between personal wealth and the propensity to start a new business. Defining business ownership rather than self-employment as the entrepreneurial outcome measure is also shown to be critical. Using self-employment leads to selection bias and underestimates the impact of personal wealth. The results imply that efforts aimed at relieving the liquidity constraints of single women could help further accelerate the recent rise of female entrepreneurship.     

Education and growth with endogenous debt constraints

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.

Bank lending and interest on excess reserves: An empirical investigation

This paper econometrically tests for effects on bank lending of the Federal Reserve’s policy of paying interest on excess reserves (IOER). Following the 2008 financial crisis, US banks decreased their loan allocations and increased holdings of excess reserves. A model of bank asset allocation shows that when the rate of IOER is higher than other short-term rates, banks will switch from zero excess reserves to a regime with higher excess reserves and lower lending. Using a sample of panel data on US banks from 2000 through 2018, we find evidence of a switch to a positive excess reserve regime in the post-crisis period. Controlling for market interest rates, loan demand, and economic activity, we find that IOER accounts for the majority of the decline in bank lending after the financial crisis.     

Entrepreneurship and Liquidity Constraints: Evidence from Sweden

Hurst and Lusardi (2004) use a specification with higher‐order polynomials to estimate the relationship between wealth and entrepreneurship. They find evidence against the existence of extensive liquidity constraints in the United States. In this paper, their approach is replicated on Swedish data. A positive relationship between wealth and entrepreneurship is found, which supports the liquidity constraints hypothesis. Alternative methods for handling the endogeneity problem and distinguishing between absolute decreasing risk aversion and liquidity constraints lend further support to the hypothesis. The analysis suggests that there exist liquidity constraints in Sweden, which are possibly more extensive than in the United States.     

Collateral restrictions and liquidity under-supply: a simple model

We show that very little is needed to create liquidity under-supply in equilibrium. Credit constraints on demand by themselves can cause an under-supply of liquidity, without the uncertainty, intermediation, asymmetric information or complicated international financial framework used in other models in the literature. We show that the under-supply is a non-monotone function of the demand distortion that causes it, a result that may have interesting implications for emerging markets economies. Finally, when we make the credit constraint endogenous, the inefficiency can be large due to the presence of a multiplier.

Are stocks desirable in tax-deferred accounts?

Existing literature suggests that, in order to maximize the tax benefit of retirement accounts, investors should follow a “pecking order” location rule of placing highly taxed assets (e.g., bonds) in a tax-deferred account and lightly taxed assets (e.g., stocks) in a taxable account. Empirical evidence, however, documents that a large number of investors violate this rule. In this paper, we show that such violations can be optimal for risk-averse investors who face portfolio constraints. In particular, while the strategy of placing bonds in the tax-deferred account maximizes the expected level of tax benefit, it may lead to volatile benefits under different realizations of stock returns. By holding a similar portfolio in both accounts, investors can achieve a more balanced growth in the two accounts, minimize the likelihood of violating the constraints in the future and hence “smooth” the volatility of the tax benefit. For some risk-averse investors, this smoothing motive can lead to the observed violation of the pecking order location rule. Our model predicts that such violations are more likely when future tax benefits are more volatile, which can occur, for example, when: (i) the tax rate differential across assets increases over time due either to tax law changes or to tax bracket changes for investors; (ii) asset returns are more volatile; and (iii) investors anticipate large future liquidity needs.     

A model of housing and credit cycles with imperfect market knowledge

The paper presents a model of housing and credit cycles featuring distorted beliefs and comovement and mutual reinforcement between house price expectations and price developments via credit expansion/contraction. Positive (negative) development in house prices fuels optimism (pessimism) and credit expansion (contraction), which in turn boost (dampen) housing demand and house prices and reinforce agents׳ optimism (pessimism). Bayesian learning about house prices can endogenously generate self-reinforcing booms and busts in house prices and significantly strengthen the role of collateral constraints in aggregate fluctuations. The model can quantitatively account for the 2001–2008 U.S. boom-bust cycle in house prices and associated household debt and consumption dynamics. It also demonstrates that allowing for imperfect knowledge of agents, a higher leveraged economy is more prone to self-reinforcing fluctuations.     

Liquidity constraints, precautionary saving and aggregate consumption: an international comparison

This paper has three objectives. First, to expand Hall's [J. Polit. Econ. 86 (1978) 971] rational expectations permanent income/life cycle hypotheses (REPIH/RELCH) representative agent model to allow for current income consumers, the durable component of total consumer expenditures and for intertemporal substitution, which are often cited as the main reasons for the rejection of Hall's model. Second, to apply this modified model to 20 OECD countries over the post-World War II period. The GMM estimation method is employed. Third, to examine the relative influence of liquidity constraints and precautionary saving on the cross-country variation in the proportion of current income consumers, using cross-country regressions and a non-linear model of panel data. The presence of current income consumers, which is primarily due to liquidity constraints and to a lesser extent to precautionary saving, is the major factor for the rejection of the basic REPIH/RELCH model in all OECD countries.     

我国商业银行贷款损失税收政策研究

商业银行贷款损失税收政策是银行所得税的核心问题。对于银行提取的呆账准备金能在税前多大比例扣除,商业银行、监管部门以及财税部门存在较大争议。银行贷款损失税收政策的制定应该遵循两个基本原则:首先,符合税收中性原则;其次,避免对银行提取足额准备金的行为产生制约。而我国现行的贷款损失税收政策并不符合这两个原则,因此应进行政策调整,由一般准备法改为更合理的特殊准备法。但是,在政策转变过程中需要注意两个问题:第一,特殊准备金也并不完全反映贷款的真实损失,允许其全部税前扣除也可能会导致征税不足。第二,在不良贷款比例很高的情况下,由一般准备法改为特殊准备法,税前扣除额可能会大幅度增加,因此需要考虑到政策变动对我国税收收入的影响。     

Do liquidity constraints generate excess sensitivity in consumption? New evidence from a sample of post-bankruptcy households

Previous work linking liquidity constraints to excessive consumption sensitivity have used household level information on wealth and assets to split the sample into households that are likely to be constrained from those with access to credit and liquidity. In this paper, we use the sample splitting methods of previous authors but refine the criteria by using direct information on whether the household filed for bankruptcy in the last 10 years. Legally, a flag can appear on a bankruptcy filer’s credit report for up to 10 years after bankruptcy. This bankruptcy flag affects an individual’s credit score, and therefore the individual’s access to credit, which may make post-bankruptcy consumers liquidity constrained. Our results indicate that post-bankruptcy consumers exhibit excess sensitivity likely due to the bankruptcy flag. Consistency checks confirm that the source of sensitivity is due to liquidity constraints and not other observationally equivalent behavior.     

Liquidity constraints and labor supply

In this paper we shed some light on how restrictions in financial markets, the so-called liquidity constraints, might act in affecting labour supply decisions of Italian workers. One way to neutralize the existence of binding liquidity constraints is simply by supplying additional labor, instead of reducing consumption. We estimate whether resorting to additional labor supply as a smoothing consumption device is at work by using the Italian Survey of Households Income and Wealth (SHIW). The longitudinal dimension of the SHIW dataset allows us to control for individual unobserved heterogeneity. We also use an IV strategy to address the endogeneity of our measure for credit constraints in labor supply equations due to time varying factors.Our results show that liquidity constraints increase the intensity in the supply of men׳s labor. Constrained men work, on average, 4 hours more than their unconstrained counterpart. Self-employed workers turn out to be more sensitive to binding liquidity constraints, possibly because they are more flexible in adjusting the intensity of their labor supply.     

The local bifurcation of Ramsey equilibrium

Summary The elasticity of substitution has been proposed as one factor in the generation of aggregate fluctuations in dynamic models with incomplete markets. We study the existence of periodic solutions in a one-sector neoclassical capital accumulation model under borrowing constraints with infinitely-lived heterogeneous agents. A dynamical system representing an equilibrium profile with only the most patient agent holding capital is analyzed when capital income is not an increasing function of total capital. Conditions for the linear approximation system at a steady state to have an eigenvalue of — 1 are found. A one-parameter family of maps based on a perturbation of the production function is introduced and the dynamical system is reduced to 1 dimension via an application of a center manifold theorem. Conditions for a stable flip bifurcation are shown to hold at the steady state.This paper is dedicated to Professor Nicolas Spulber, one of the great pioneers in the study of growth theory. He brought us together and encouraged our joint work on Ramsey equilibrium theory.We thank Nicolas Spulber for his usual insightful comments and we thank Michele Boldrin for a useful discussion. We also thank a referee for suggesting improvements in the paper as well as the seminar participants at the University of Rochester and Cornell University for their comments on the paper.     

Debt, liquidity and dynamics

Summary. Money, which provides liquidity, is distinct from debt. The introduction of a bank that issues money in exchange for debt and pays out its profit as dividend to shareholders modifies the model of overlapping generations. The set of equilibrium paths, their dynamic properties, as well as the scope and effectiveness of monetary policy are significantly altered: though low rates of interest are associated with superior steady state allocations, stability of the steady state may require a nominal rate of interest above a certain minimum: without production, a decrease in the nominal rate of interest may result in explosive behavior or convergence to an endogenous cycle, while in an economy with production, an increase in the nominal rate of interest may lead to indeterminacy and fluctuations.Received: 5 October 2004, Revised: 5 November 2004 JEL Classification Numbers: E30, E32, E50, E52.C.

Precautionary saving under liquidity constraints: Evidence from rural Pakistan

This paper investigates precautionary saving under liquidity constraints in Pakistan using household panel data. In particular, while it estimates Kimball's [Kimball, M.S. Precautionary saving in the small and in the large. Econometrica 1990; 58; 53–73.] prudence parameter based on a framework that is similar to Dynan [Dynan, K.E. How prudent are consumers? Journal of Political Economy 1993; 101; 1104–1113.], this study deviates from the framework by explicitly considering liquidity constraints, as in Zeldes [Zeldes, S.P. Consumption and liquidity constraints: an empirical investigation. Journal of Political Economy 1989; 97; 305–346.]. By doing so, this paper attempts to differentiate the standard precautionary saving caused by uncertainty from that caused by liquidity constraints. Furthermore, endogenous liquidity constraints are used in order to resolve issues of selection biases. We find substantial evidence of the presence of precautionary saving in Pakistan. More specifically, the estimated prudence is significantly higher for liquidity-constrained households as compared with unconstrained ones. The finding suggests that the precautionary saving motives appear stronger when households see that their access to credit markets is limited.     

Regret theory and the banking firm: The optimal bank interest margin

This paper examines the optimal bank interest margin, i.e., the spread between the loan rate and the deposit rate of a bank, when the bank is not only risk-averse but also regret-averse. Regret-averse preferences are characterized by a utility function that includes disutility from having chosen ex-post suboptimal alternatives. We show that the presence of regret aversion raises or lowers the optimal bank interest margin than the one chosen by the purely risk-averse bank, depending on whether the probability of default is below or above a threshold value, respectively. Regret aversion as such makes the bank less prudent and more prone to risk-taking when the probability of default is high, thereby adversely affecting the stability of the banking system.

Managerial efficiency in Taiwan bank branches: A network DEA

Taiwan's banking industry remains highly fragmented and competitive after a series of financial liberalization and restructuring. With the enforcement of these fiscal policies, domestic banking institutions face a more dynamic, increasingly intense and highly competitive environment even as the banking industry's overall efficiency has gradually been enhanced. This structural change has further forced individual banking institutions, especially state-owned banks, to inspect the performance of their branches and identify improvement directions so as to gain further competitive advantages. To conduct a valid, fair and reliable evaluation on Taiwan's bank branches, we integrate a two-stage series performance model and fuzzy multiobjective model. A new scheme that considers the complementation of production and intermediation activities within a branch and overcomes the shortage of the traditional network DEA methodology about DMUs cannot be assessed on a common base. The results indicate that the overall performances of mixed ownership bank branches are superior to those of state-owned bank branches, representing that the advantages of banking privatization have some remedial effects for improving the managerial inefficiency of state-owned banks. In addition, the sensitivity analysis and decision-making matrix herein help bank management to identify branches' efficiency, weakness, and directions for improvement.     

Central bank reserve management: Aggregate targets and interest payments on reserves

Tindall and Spencer [1997] presented a dynamic stochastic theory of borrowed reserves that explained the observed nonlinear relationship between borrowing and the spread between the federal funds rate and the discount rate. It showed that borrowed reserves are a function of deposit variation. This paper extends that research, providing a general dynamic model of all key bank reserve aggregates. Nearly all reserve aggregates, which can be used as operating targets by the Federal Reserve, are subject to the influence of deposit variation and are nonlinearly related to the spread between the federal funds rate and the discount rate, complicating their use as targets. Additionally, it is found that the Federal Reserve's proposal to pay interest on bank reserves could generate substantial distortions in reserve aggregate behavior where interest is paid on excess reserves as well as required reserves, effectively resulting in potentially large discount-window policing problems.     

The impact of liquidity constraints on the cash-futures basis dynamics: Evidence from the Chinese market

This study investigates the impact of liquidity constraints on the dynamics of the cash-futures basis in the Chinese futures market. By analyzing the trading behaviors of hedgers, speculators, and arbitrageurs in a liquidity constraint context, we document two effects: the expectation effect and the liquidity effect. We further propose a set of threshold vector error correction models (VECMs) for the CSI 300 index and CSI 300 index futures to examine these two effects separately and jointly. We find evidence for both effects. We also find that a basis-liquidity-based threshold VECM, which includes both effects, performs well in explaining why the degree of persistence of a large basis depends on the direction of divergence in the cash-futures price relationship, a stylized fact we observe in the Chinese futures market.
