Credit rationing as a (temporary) suboptimal equilibrium with imperfect information

Jaffee and Russell (1976) characterized partial rationing as a contract rate and contract size below those of the no-rationing equilibrium. Their non-price rationing here obtains as a suboptimal equilibrium for a risk-averse rate-setting intermediary with marginal increasing cost and a monopolistically competitive loan demand. The temporary (dis)equilibrium corresponds to a dominated strategy, and the wider class of models of which J-R's solution is but a singular case is touched upon.     

Credit rationing and capital accumulation with investment and consumption loans revisited

A simple model is developed to evaluate the roles of credit rationing and government policies of financial repression in the process of capital accumulation. In the model, credit rationing on both investment and consumption loans decreases as capital accumulates but increases as the government imposes policies of financial repression to a greater extent. While a reduction in credit rationing on consumption loans impedes capital accumulation, such a reduction on investment loans facilitates it. We find that developing countries may be trapped at a low-capital-stock steady state while developed countries converge to a high-capital-stock steady state. Instead of adopting policies of financial liberalization, interestingly, this paper finds that policies of financial repression may enable developing countries to escape the development trap.     

Rationing rules and Bertrand-Edgeworth equilibria in large markets

In a market with concave downward sloping demand and symmetric firms which compete in prices with constant marginal costs and capacity limits it is shown that the supports of the symmetric (mixed strategy) Nash equilibria converge to the unique competitive price provided that unsatisfied demand is allocated according to the surplus-maximizing rationing rule.     

The optimal minimum wage with regulatory uncertainty

For two different regulatory standards, we examine the optimal minimum wage in a competitive labor market when the government is uncertain about supply and demand. Solutions are related to underlying supply and demand conditions, and to the extent of uncertainty and of rationing efficiency. With expected earnings maximization, greater uncertainty widens the range of parameter values for which a minimum wage should be set. With expected worker surplus maximization and sufficiently efficient rationing, a minimum wage should always be set. However, in both cases regulatory uncertainty may require a low minimum wage that may not bind in equilibrium.     

The healthcare rationing debate: more clarity by separating the issues?

Summary

The rationing debate is often confused by dealing with several different issues concurrently. This paper introduces a typology and matrix that separate two of the most important of these issues: the transparency of the debate and the mode of rationing itself. The transparency of the debate is the need to think about how to deal with the following political issue: should the rationing of medical care happen tacitly and be left to the parties involved (implicit), or should it be open to public scrutiny and debate (explicit)? At the same time (but to be examined independently) there is the mode of rationing: how are the responsible parties to develop ways of allocating scarce resources? This can be achieved either implicitly, e.g. via clinical bedside reasoning, or explicitly, i.e. openly with the aid of rigorously developed and tested algorithms. Thinking about these issues separately may help to bring more clarity to the rationing debate. This paper also discusses some implications resulting from such a separation.     

农地确权、信贷配给释缓与农村金融的深度发展*

作为一项基础性、制度环境层面的变革，农地确权帮助更多农户进入金融市场、促进农村金融宽度意义上的“量”变作用已经初步显现。但是，它是否可以提高农户贷款数量，缓解信贷配给并促进农村金融深度意义上的“质”变？这是一个重要但鲜有研究的问题。本文从供给、需求、交易成本、价格、风险配给等角度，分析了农地确权缓解信贷配给、促进农村金融深度发展的理论机理，并通过有序多分类变量回归及倾向得分匹配方法进行实证分析。研究表明，农地确权对农户金融参与深度的影响主要表现为：因降低信息成本而缓解价格配给，因弱化农户的损失规避心理而缓解风险配给；同时，数量配给和交易成本配给的释缓作用尚未充分显示。     

Is Rationing an Option for Approaching Healthcare Services Provision? The Case of the Greek Cardiac Patients

This paper attempts to address some of the issues surrounding rationing of healthcare services, with application to Greece’s delivery of cardiac services. To this end, first, we provide highlights of the current debate concerning rationing worldwide and critically discuss them. Following that, an empirical analysis of the way ‘key’ stakeholders perceive rationing issues in Greece, is performed. Findings indicate that rationing is a highly disputed approach, subject to individualistic interpretations and moral issues. At policy level, it becomes evident that rationing is a mixture rather than a single policy concern, depending on a complicated range of locally-based reconciliation made at various levels of interested parties. Hence, no universal formula exists to fit all countries’ healthcare systems and further case-by-case research, is required.     

A revealed preference test of rationing

This paper derives a revealed preference test for utility maximization under rationing and can detect, for which goods rationing is binding without specifying a functional form or imposing rationing constraints prior to estimation. For UK data from 1920–55, we find evidence of utility maximization under rationing with rationing binding for food and other services. Estimated virtual prices exceed observed food prices by 16.5% in 1947 and observed prices of other services by 10.9% in 1952.     

On the theory of effective demand under stochastic rationing

The concept of effective demand under stochastic manipulable quantity rationing is shown to be compatible with the existence of nontrivial equilibrium. It is argued that stochastic rationing is unavoidable for any satisfactory definition of effective demand. Moreover, manipulability of the rationing mechanism is necessary for reasons of logical consistency, at least if the distribution over realisations for each agent depends on his own action and on the aggregate values of demand and supply only. In that case, anonymous stochastic rationing schemes reduce to those random functions, the mean value function of which is the uniform proportional rationing mechanism.     

The underground economy and its macroeconomic consequences

This study develops a dynamic general equilibrium model in which optimizing agents evade taxes by operating in the underground economy. The cost to firms of evading taxes is that they find themselves subject to credit rationing from banks. Our model simulations show that in the absence of budgetary flexibility to adjust expenditures, raising tax rates too high drives firms into the underground economy, thereby reducing the tax base. Aggregate investment in the economy is lowered because of credit rationing. Taxes that are too low eliminate the underground economy, but result in unsustainable budget and trade deficits. Thus, the optimal rate of taxation, from a macroeconomic point of view, may lead to some underground activity.     

商业银行信贷配给对中国房地产业波动的影响*

商业银行信贷配给控制中国房地产业信贷规模和结构,造成供给和需求的规模与结构扭曲,影响货币政策和财政政策的调控效果,容易引起房地产业波动。本文通过构建信贷配给模型,测算不同波动时期当中,商业银行信贷配给程度的变化趋势,以及对房地产业的影响。实证结果显示,信贷配给程度的变化与房地产业波动显著相关,信贷配给改变了投资和消费在推动房地产产出过程中的结构,并制约路径依赖对产出的影响,同时影响财政政策和数量型货币政策稳定房地产业的效果。本文认为,可以通过逐渐弱化商业银行在房地产金融市场中的垄断地位,丰富房地产信贷供给层次和结构,以及加强信贷供给监督来缓解信贷配给的消极作用。     

Do Banks Ration Credit to New Enterprises? And Should Governments Intervene?

Do banks deny credit to new start–ups? The presumption that they do has motivated government intervention in several forms, including publicly backed loan guarantee schemes in the UK and elsewhere. This paper presents an overview of the modern theory and evidence of credit rationing, and concludes that the case for credit rationing is weak. Ultimately, theoretical arguments for or against credit rationing are inconclusive, so evidence is needed to decide the issue. The evidence is not supportive of the view that credit rationing is an important or widespread phenomenon.     

Public Sector Rationing and Private Sector Selection

We study the interaction between nonprice public rationing and prices in the private market. Under a limited budget, the public supplier uses a rationing policy. A private firm may supply the good to those consumers who are rationed by the public system. Consumers have different amounts of wealth, and costs of providing the good to them vary. We consider two regimes. First, the public supplier observes consumers’ wealth information; second, the public supplier observes both wealth and cost information. The public supplier chooses a rationing policy, and, simultaneously, the private firm, observing only cost but not wealth information, chooses a pricing policy. In the first regime, there is a continuum of equilibria. The Pareto dominant equilibrium is a means‐test equilibrium: poor consumers are supplied while rich consumers are rationed. Prices in the private market increase with the budget. In the second regime, there is a unique equilibrium. This exhibits a cost‐effectiveness rationing rule; consumers are supplied if and only if their cost–benefit ratios are low. Prices in the private market do not change with the budget. Equilibrium consumer utility is higher in the cost‐effectiveness equilibrium than the means‐test equilibrium.     

General equilibrium and the emergence of (non)market clearing trading institutions

We consider a pure exchange economy, where for each good several trading institutions are available, only one of which is market-clearing. The other feasible trading institutions lead to rationing. To learn on which trading institutions to coordinate, traders follow behavioral rules of thumb that are based on the past performances of the trading institutions. Given the choice of institutions, market outcomes are determined by an equilibrium concept that allows for rationing. We find that full coordination on the market-clearing institutions without any rationing is a stochastically stable outcome, independently of the characteristics of the alternative available institutions. We also find, though, that coordination on certain other, non-market-clearing institutions with rationing can be stochastically stable.     

From managed care to "financed care"

Paying for health care in the new millennium may require fundamental restructuring of how costs are managed to avoid rationing and a government takeover.     

Financial constraints and unemployment equilibrium

The aim of this paper is to show that a robust determination of unemployment equilibria can be based on the integration of credit rationing into a general equilibrium model. We first review some of the Keynesian macroeconomic models. We show that the problems bequeathed by Keynes’ legacy are only partially solved by the strand of the new Keynesian economics based on market imperfections and endogenous rigidities. In order to overcome these problems we refer to credit rationing. In particular, we build a simple general equilibrium model in which prices are–in principle–perfectly flexible and credit rationing implies unemployment equilibria.     

Credit rationing or overlending? An exploration into financing imperfection

Small and new firms are deemed to be unable to obtain sufficient bank loans. This idea finds a strong theoretical support in credit rationing theory. However, this is vigorously challenged by De Meza and Webb (1987, 2000) suggesting that firms can benefit from an excess of credit, i.e. overlending. Credit rationing or overlending? The contribution of this empirical article is twofold: to our knowledge, it is the first to make an attempt in measuring the relative importance of these two types of financing imperfection and to explore factors leading to one or the other. We exploit a rich panel data set on the access to bank credit for new French businesses during the mid-1990s. Our results show that credit rationing was not highly spread among French new firms. The story told by De Meza and Webb (1987) appears to be a much more realistic model. In addition, we identify factors, linked to the starter, the project or the industry, that are closely associated with credit rationing and/or overlending. Most factors enter into a consistent relation: when they are positively (negatively) associated with credit rationing, they are negatively (positively) associated with overlending.     

Industry equilibrium with outside financing and moral hazard: Implications for market integration

In this paper, we study industry equilibrium under the assumptions that (1) firms need outside financing and (2) they have a moral hazard problem in taking potentially excessive risks. We characterize an industry equilibrium with credit rationing, where firms choose not to take risks, and compare this to the industry equilibrium in the absence of credit rationing. In both cases, we show that competition increases and prices decline as markets integrate. However, in markets with credit rationing there is typically more exit, a smaller decline in prices and, most strikingly, the market value of the industry increases rather than decreases.     

Credit rationing, interest rates and capital accumulation

A simple endogenous growth model is developed to characterize credit rationing through the capital accumulation process. The model shows that credit rationing on investment loans decreases as capital accumulates and the enforcement cost decreases. We find that the evolution of the interest rate factor (lending interest rate/depositing interest rate) has a similar pattern to the credit rationing probability. However, simulations show that the evolution of the interest rate spread through the capital accumulation process depends on the degree of the enforcement cost. In the empirical part of the paper, we consider fifty-two countries, at different stages of development, over the period 1995–2005. We confirm the theoretical findings relative to the evolution of the interest rate spread and interest rate factor with capital accumulation. These results suggest that, for economies endowed with costly contract enforcement, the interest rate factor could be a better proxy of credit rationing than the interest rate spread.     

A note on decentralizability in consumer demand models with quantity rationing

It is shown that in a context of quantity rationing, it is not always possible to decentralize the consumer's intertemporal behavior in a sequence of atemporal, static optimization programs. Whether or not decentralizability holds crucially depends on the perceived rationing scheme.
