A post‐Keynesian model of output,employment and monetary demand

This paper presents a simple model based on three broad Post‐Keynesian hypotheses: (1) the economic process develops over time; (2) money is endogenous; and (3) producers are price setters. To make the analysis easier we also assume (4) that firms are vertically integrated. Producers assess the expected demand and ask banks for credit in order to start production; banks create credit at the request of producers to finance the wage bill; workers buy goods sold by firms; firms must repay banks the amount borrowed plus interest and earn a target rate of profit. Since firms have created only as much purchasing power as they have advanced to workers in the form of the wage fund, equilibrium requires that there is an amount of autonomous monetary demand equal to profits and interest. Furthermore, in order to make the value of supply equal to the value of effective demand, firms will employ the number of workers necessary to create the purchasing power which, when added to the anticipated autonomous demand, enables all costs to be covered and the planned rate of profits to be attained.     

Credit creation under multiple banking regulations: The impact of balance sheet diversity on money supply

Since the recent financial crisis along with more concentration of banking supervision, we have stepped into a new regulatory regime where multiple regulations are at play simultaneously. In this paper, we study the collective impacts of multiple regulations on credit creation in a heterogeneous banking system. Each single regulation imposes a constraint on credit creation for each bank, while with multiple regulations, only the most stringent one plays the determinant role on money supply. For the homogeneous banking system with identical balance sheets, they share the same binding regulation. In contrast, for the heterogeneous banking system with diverse balance sheets, the binding regulation for each bank may be different from other's. Those banks, who are bound by different regulatory constraints from homogeneous banks, would bring about an overall reduction in money supply, because those binding regulations impose a lower capacity (compared with the one in the case of homogeneous banks) for the banks to extend their balance sheets in this condition. We put forward an agent-based model of commercial banks integrated with two processes: credit creation and fund transfer, to demonstrate the reduction effect. The results facilitate the understandings of the transmission mechanism of monetary policy via banks and its interaction with prudential regulations.     

Credit cards and aggregate money demand

This paper attempts to assess the effect of the growth in the use of credit cards upon aggregate household money holdings. In an inventory theoretic structure, when individuals have the choice of whether to use a credit card as an alternative means of payments, and with a given income distribution, the aggregate money demand relation is derived. It is shown that the existence of an alternative means of payment changes the predictions on the relevant elasticities from the standard model, and makes them variable over time, and gives some indication of how credit card growth causes shifts in aggregate money demand.     

垄断型信贷市场融资担保问题分析--以民营中小企业融资为例

民营中小企业在转型经济条件下的垄断型信贷市场中很容易受到信贷歧视,商业银行对此类企业的"惜贷"乃至拒贷不仅反映出非公有制经济主体差强人意的融资地位,而且从一个侧面折射出计划金融体制对于商业银行市场化改革的种种束缚作用以及在金融改革滞后的情况下商业银行信贷行为的严重不合理性.本文试图通过建立一个垄断型信贷市场融资担保模型来分析市场垄断和利率管制对民营中小企业融资的不利影响,担保对于缓解民营中小企业融资难问题所能发挥的积极作用,以此说明改革我国金融体制、开放信贷市场和实行利率自由化的必要性.     

Increasing inequality,consumer credit and financial fragility in an agent based macroeconomic model

We investigate the interplay between increasing inequality and consumer credit in a complex macroeconomic system with financially fragile heterogeneous households, firms and banks. Simulation results show that there are pros and cons of introducing consumer credit: on the one hand, for a certain time, it leads to lower unemployment through boosting aggregate demand; on the other hand, it accelerates the system tendency to the crisis. Since the increase of financial profits goes with a decline of households’ real wealth, a policy trade-off emerges.     

Do credit unions have distinct objectives? Evidence from executive compensation structures

Credit unions compete directly with commercial banks in markets for consumer financial services yet receive an exemption from federal corporate income tax. Commercial banks claim that credit unions are no different than banks and that the credit union tax exemption represents an unfair competitive advantage. Credit unions counter that while they offer similar products and services, they differ from commercial banks in terms of structure and mission, given their not-for-profit, cooperative status. In this paper, we test for substantive differences in the objective functions of commercial banks and nonprofit credit unions by comparing CEO compensation structures. Drawing on the relevant principal–agent literature, we provide several arguments to support the hypotheses that credit union boards of directors establish lower-powered incentive contracts with their CEOs relative to similarly sized commercial banks, and offer lower total compensation. We find that credit union CEOs receive approximately 250% less performance-based compensation relative to CEOs of similarly sized community banks. Bank CEOs also earn approximately 15% to 20% more total compensation on average. The results are generally robust to controlling for CEO- and board-level characteristics, local economic conditions, and institution-level indicators of size, growth, complexity, liquidity and risk. The findings suggest important differences in incentive structures and objectives between banks and credit unions.     

The size distribution of the banking sector and the effects of monetary policy

In recent years, the industrial organization of the banking system has received a large amount of attention. In particular, it is generally viewed that the size distribution of the banking sector has changed where it is dominated by a small number of large institutions. In this paper, we develop a model of imperfectly competitive banks that differ in terms of the size of their deposit base. Such differences are important for aggregate credit market activity and the effects of monetary policy. Notably, we explain how the optimal size distribution of the banking system involves trade-offs from distortions in credit markets due to imperfect competition across banking markets. Second, the effects of monetary policy on credit market activity are weaker in an economy dominated by a small number of large banks. Empirical analysis examining the role of concentration among the current members of the European Monetary Union is consistent with the predictions of the model.     

Aggregation and the existence of a social utility function

In a well-known paper Gorman (Econometrica21 (1953)) established that the necessary and sufficient condition for the existence of an aggregate, or social, utility function, independent of the distribution of income, is that all individuals' income consumption paths be parallel straight lines. Recently Chipman (J. Econ. Theory8 (1974)), building on the paper of Hurwicz and Uzawa (in “Preference Utility and Demand”) has shown that if the distribution of income is proportional and individual preferences are homothetic, aggregate consumption behavior obeys the necessary integrability conditions. It is shown here that the consistency of aggregate behavior can be derived from more general conditions than the ones used by Chipman and Gorman. Examples of demand systems from which aggregate behavior implies a social utility function are provided. It is then shown that if individual demand functions are linear in income—a form employed by both Gorman and Chipman—it is not necessary that the distribution of income be fixed.     

Constructing the Monetary Conditions Index for China

How can we fit different monetary transmission channels together to understand the effect of China’s monetary policy? This paper focuses on China’s monetary conditions and aggregate demand in terms of the monetary conditions index (MCI), which has been widely used as an important indicator for central banks, financial institutions, and scholars. To construct an MCI in the context of China over 1987Q1–2010Q2, we consider three channels through which monetary conditions might influence aggregate demand: the primary lending rate, the real effective exchange rate, and the bank credit. The weights of the component variables are obtained by estimating both the IS equation and the vector autoregressive model (VAR), which yield somewhat similar results. Further empirical tests show that the MCIs we derived contain useful information about future output growth and inflation in China over the short and medium term. From a historical perspective, the MCI we derived is more informative than individual monetary variables for the understanding of the development of China’s monetary conditions between 1987 and 2010.     

Credit Availability and Capital Crunch: On the Role of the Heterogeneity of the Banking System

We analyze the impact of a credit crunch on aggregate investment via the heterogeneous structure of the banking system. We develop a model of endogenous credit allocation in which investors and two banks differ according to their level of capital and monitoring technology. In a context of moral hazard problem, we show that banks' cost advantage in the monitoring of small businesses must be compared to their relative amount of capital in order to explain firms' optimal choice of financing, the credit allocation in the economy and the asymmetric impact of a credit crunch on aggregate investment. A shock of the same magnitude on the two banks level of capital may have a different effect on total investment. We stress that the credit crunch is maximum when the shock hits the bank specialized in the financing of small businesses and when this bank is also the less capitalized. This result is supported by recent empirical studies ( Hancock and Wilcox 1998 ).     

The Financial Stability Board and Switzerland’s WiR-Credit Mechanism

Abstract:

The incentives banks face, such as the Basel Capital Accords, motivate them to favor lending with collateralized assets, rather than lending to Small-Medium Enterprises (SMEs), with associated profound economic consequences for society. Since the 1970s there has not been any direct oversight of whether or not credit contributes to GDP. We need a macroeconomic policy tool that can discriminate among different categories of credit extended to curb speculation in existing assets (non-GDP) and promote new business investment (GDP).

Government money creation and private credit growth are often presumed the only two ways to enhance nominal demand, yet the Swiss Economic Circle (Wirtschaftsring-Genossenschaft or WIR) is a Swiss Bank whose creation of purchasing power for SMEs has counter-cyclically stabilized the Swiss economy for over 80 years. The Financial Stability Board (FSB) should create localized credit-creation architectures utilizing a Swiss-WIR type currency to funnel credit that reflects systemic and macroeconomic risks that individually will never be rational for banks left to themselves.     

Does income inequality really matter for credit booms?

This paper addresses the question whether income inequality is associated with credit booms, alongside other macroeconomic factors. We distinguish between the different types of credit booms—real estate credit booms, household credit booms, firm credit booms and credit booms that turn into crises. Furthermore, our analysis of a sample of 70 countries between 1990 and 2016 does not provide any evidence of credit booms driving income inequality. We observe that capital inflows increase the likelihood of credit boom occurrence, while countries experiencing high economic growth tend to have more credit booms. Finally, we note that credit booms are more frequent in countries with fixed exchange rate regimes.     

发展中国家内、外资银行信贷行为差异分析

众多发展中国家的金融改革实践表明,银行业开放的正负效应并不具有显著的国别一般性,特别是在信贷稳定性上,在东道国和外资银行母国经济运行的不同时期,外资银行与东道国国内银行的信贷行为可能存在较大的差异性,进而对东道国的经济金融稳定带来不同的影响。本文从全球范围内抽取了21个发展中国家（地区）和转轨国家中的400余家内、外资银行为样本,以其在2002～2010年间的相关数据构成面板数据集,来对内、外资银行在此期间的信贷行为差异进行检验。研究发现,外资银行的信贷行为确实与国内银行存在着差异性,主要表现在外资银行的信贷增长既表现出与东道国的经济增长显著正相关,又明显受到母国经济状况的影响;在经济正常的年份里,外资银行的信贷表现更多的取决于东道国的经济状况,而当外资银行母国发生经济危机时,却会对外资银行的信贷增长造成较大的负向冲击。     

Macroeconomic Fluctuations and Bank Lending: Evidence for Germany and the Euro Area

Abstract. This paper analyzes the dynamic response of loans to the private sector and of economic activity to aggregate supply, demand and monetary policy shocks in Germany and the euro area based on a standard macroeconomic VAR using sign restrictions to identify the structural shocks. The main results of this analysis are that (i) with the exception of the response to the supply shock in Germany, the response of loans to the three macroeconomic shocks is rather weak and in most cases insignificant; (ii) the 2000–05 credit slowdown and weak economic performance in Germany were primarily driven by adverse supply shocks; and (iii) the marked slowdown in credit creation in Germany over this period actually represents a realignment of the outstanding stock of loans with its deterministic level. In order to assess the role of bank lending in the transmission of macroeconomic shocks, we further perform counterfactual simulations and analyze the dynamic responses of German loan subaggregates in order to test the distributional implications of potential credit market frictions. These exercises do not indicate that credit market frictions play an amplifying role in the transmission of macroeconomic fluctuations.     

Estimating the direct impact of bank liquidity shocks on the real economy: Evidence from letter‐of‐credit import transactions in Colombia

This study identifies and provides an estimate of the impact of bank liquidity shocks on real economic activity by exploring letter‐of‐credit import transactions in Colombia during the 2008 to 2009 global financial crisis. The detailed dataset on letter‐of‐credit transactions allows for exploiting within‐importer–exporter variation across issuing banks. The study finds substantial effects of bank liquidity shocks on letter‐of‐credit import transactions: banks that were more vulnerable to adverse liquidity shocks—proxied by the ex ante reliance on wholesale funding or borrowings from foreign banks—reduced letter‐of‐credit issuances more in both intensive and extensive margins. The study also confirms that it had real effects: importer–exporter pairs that relied more on letter‐of‐credit transactions experienced a greater reduction in their total imports in response to adverse bank liquidity shocks.     

Enforcing the 1988 Basel Capital Requirements: Did it Curtail Bank Credit in Emerging Economies?

We examine whether the enforcement of bank capital asset requirements (CARs) curtailed the supply of credit in emerging economies. Preliminarily, we identify 16 emerging economies that – according to official and impartial reports – enforced the 1988 Basel standard during the 1990s. Then we perform our twofold econometric analysis. In the former part, we use macro data to test whether, controlling for economic fundamental variables, the enforcement brought about a slowdown in aggregate credit in these countries vis-a-vis other emerging economies. We find some support for our hypothesis. In the latter part, we employ individual bank data to better identify the 'capital crunch' effect of the enforcement. Here, we find that CAR enforcement – according to the 1988 Basel standard – significantly curtailed credit supply, particularly at less well-capitalized banks. The two empirical parts together suggest that the CAR enforcement did curtail aggregate credit in the examined emerging countries and that this result is rooted in the attempt by under-capitalized banks to reduce their loans. We argue that among developing countries – where banks are often the only source of financial intermediation – the positive effect of higher capital requirements, represented by the reduction of poor quality lending, may be offset by their negative impact on bank liquidity and on the level of economic activity. Hence, our results suggest that particular care is required to avoid potential negative macroeconomic effects when phasing in new and higher capital requirements in emerging economies.

Dynamic behavior of product and stock markets with a varying degree of interaction

We develop a macroeconomic behavioral model in order to analyze the interactions between product and financial markets. The real subsystem is represented by a simple Keynesian income–expenditure model, while the financial subsystem is represented by an equilibrium stock market with heterogeneous speculators, i.e., chartists and fundamentalists. The interactions between the two markets are modeled in the following way: the aggregate demand depends, among other variables, also on the stock market price, while the fundamental value used by speculators in their decisional process depends on the real sector economic conditions. In our model we introduce a parameter that represents the degree of interaction. With the aid of analytical and numerical tools we show that an increasing degree of interaction between markets tends to locally stabilize the system. This stabilization occurs via a sequence of period-halving bifurcations. Globally, we find that the stabilization process implies multistability, i.e., the coexistence of different kinds of attractors.     

Shaken or Stirred? Financial Deregulation and the Monetary Transmission Mechanism in Norway

Is there a credit channel for monetary policy? Has the deregulation of financial markets had any temporary or permanent effects on the monetary transmission mechanism? We present empirical evidence on these issues for Norway by estimating a dynamic system of money, credit, real income and inflation. We find that the deregulation process has not caused any permanent shifts in the long‐run demand functions. Within a small simultaneous dynamic model, there is some evidence for the credit view of the monetary transmission mechanism, as both credit and money exhibit strong and stable effects on aggregate demand.

绿色信贷能否缓解银行系统性风险*——基于中国22家上市银行的证据

本文选取2009—2020年中国22家上市银行年度数据，构建面板回归模型,就绿色信贷对银行系统性风险的影响及其传导机制与异质性特征进行实证分析。研究表明：绿色信贷对银行系统性风险具有抑制作用。风险承担与盈利能力在绿色信贷与银行系统性风险的关系中承担着双重中介作用。绿色信贷对银行系统性风险的影响存在异质性特征。相对于国有银行、低环境规制时期银行及经济上行期银行，绿色信贷对非国有银行、高环境规制时期银行及经济下行期银行系统性风险的抑制作用更为明显。该成果将为防控中国银行业系统性风险提供重要的理论指导与决策参考。     

外资银行进入对发展中国家银行信贷可得性的影响研究

如何引导外资银行增加东道国的信贷可得性,尤其是中小企业的信贷可得性,是目前理论和政策界争论的焦点问题之一。本文通过构建一个理论模型,分析了外资银行进入和国内信贷供给的关系,从市场均衡结果、社会福利、成本效率等几个角度对外资银行进入发展中的东道国的影响进行综合分析。模型结果表明,外资银行的进入并不必然增加一国的总体信贷水平、也并不必然提高东道国银行业的成本效率和整体社会福利,甚至在某些特定条件下,结果可能适得其反。
