隐性保险体制下城市商业银行的市场约束行为

文章分别从价格约束、数量约束、外部环境对市场约束的影响等角度,研究了基于隐性保险体制下的我国城市商业银行的市场约束行为。研究发现：（1）我国地方城市商业银行的储蓄市场不存在显著的价格约束效应,但没有证据表明一定不存在数量约束效应。（2）政府隐性保险对银行债权人的价格决策和数量决策均有显著影响,且价格决策比数量决策、短期储蓄比长期储蓄受到政府隐性保险更大的影响。（3）省会城市城商行的市场约束力度要弱于非省会城市的城商行。     

Bank behavior, incomplete interest rate pass-through, and the cost channel of monetary policy transmission

This paper employs a New Keynesian DSGE model to explore the role of banks within the cost channel of monetary policy transmission for shaping the interest rate pass-through from money market rates to loan rates. Banks extend loans to firms in an environment of monopolistic competition by setting their loan rates in a staggered way, which means that the adjustment of the aggregate loan rate to a monetary policy shock is sticky. We estimate the model for the euro area by adopting a minimum distance approach. Our findings exhibit that (i) financial costs are an important factor for price changes, (ii) frictions in the loan market have an effect on the propagation of monetary policy shocks as the pass-through from a change in money market rates to loan rates is incomplete, and (iii) the strength of the cost channel is mitigated as banks shelter firms from monetary policy shocks by smoothing loan rates.     

战略引资和网点规模对银行信贷竞争的影响

以网点规模表征银行规模,从网点吸收存款以支撑贷款业务的角度构建有信贷资金约束的贷款竞争模型,研究外资银行入股对引资银行以及本地信贷竞争的影响。结果表明:只要外资银行改善引资银行的技术水平,贷款市场竞争就会加剧;大银行的市场份额较多,贷款市场竞争加剧对其利润的负面影响较大,大银行为避免这种影响不会过度参与竞争。最后指出,决策层应制定政策以引导优质外资银行入股本地小银行以促进贷款竞争。     

Competition Tests with a Non-Structural Model: the Panzar–Rosse Method Applied to Germany's Savings Banks

Abstract. In this paper we adopt the Panzar–Rosse approach to assess the competitive conditions in the German banking market for the period from 1993 to 2002. We suggest several improvements to the empirical application of the approach and show that frequently used empirical models that apply price rather than revenue functions lead to biased results. Using disaggregated annual data from more than 400 savings banks (Sparkassen) the empirical findings indicate monopolistic competition, the cases of monopoly and perfect competition are strongly rejected. Furthermore, small banks seem to enjoy even more market power than larger institutions.     

展览产品定价模型及价格影响因素研究——基于双边市场理论视角

本文借鉴近年来兴起的双边市场理论对展览产品的定价模型及影响因素进行了理论研究。本文指出,展览市场是典型的双边市场,具有明显的网络外部性。本文通过建立垄断和竞争两种模型研究了展览产品的定价,并指出参展商和观众的需求价格弹性、一方消费者给另一方消费者带来的网络外部性、展览市场的竞争以及产品差异化都是影响展览产品定价的主要因素。     

我国航空运输服务业的市场结构及价格竞争策略分析

我国航空运输服务业从宏观上分析具有寡头垄断的市场结构特点,从航线运营的角度分析却具有垄断竞争的特点,因此我国航空运输服务市场还处在重要的发展变革阶段。在我国空运市场特定的经济环境下,旅客的购买决策受到多种因素的影响,航空公司的价格竞争主要表现为不同价格的子舱位数量的决策,并且具有复杂的价格体系。在同一航线上经营的不同企业一方面要针对价格需求弹性大和时间需求弹性大的旅客采取强硬的价格竞争策略;另一方面也要注重差异化价格竞争策略, 避免恶性竞争的发生。     

Determinants of Interest Rate Pass-through for Emerging Market Economies: The Role of Financial Market Structure

It is essential for central banks to assess whether or not the pass-through from monetary policy rates to credit and deposit interest rates is complete in order to ensure price stability. In this article, we analyze interest rate pass-through process for emerging market economies. Since emerging market countries lack large panel data sets that are typically available for developed countries, it is hard to analyze the determinants of pass-through coefficients for emerging market countries. To overcome the data issue, we developed a country selection procedure that minimizes heterogeneity among the countries included in the analysis. Our findings indicate that banking sectors?? competition plays a more important role for emerging market countries than their developed counterparts.     

银行业市场结构与货币政策冲击——基于异质性银行的模型分析

通过构造货币政策冲击下的贷款市场总体均衡模型,研究在受到资本充足率和存贷比约束的条件下,银行最优信贷决策行为。分析发现,在垄断竞争的银行业市场结构背景下,银行间在价格竞争方面表现出战略互补特征和由此带来的模仿效应。因而,当银行满足资本充足率和存贷比要求时,银行业传导的货币政策信贷渠道是有效的,而当贷款市场中的银行不能满足资本充足率或存贷比要求时,信贷渠道则表现出无效性。     

Assessing the competition in Angola’s banking industry

This article analyses the level of competition in Angola’s banking industry using the Panzar–Rosse model with data from 2005 to 2014. Competition is a vital aspect of the banking market and therefore it is central to policy-making. The results reveal that Angola banking competition is monopolist and therefore lower competition is found in Angola banks. Policy implication is derived.     

How to measure the market power of banks in the lending business accurately: a segment-based adjustment of the Lerner Index

Numerous empirical studies use the price-cost-margin-based Lerner Index (LI) to assess the general market power of banks. A common procedure within those LI applications is to approximate the market price required for the LI measurement as the ratio of a bank’s total revenues to total assets. We discuss the major flaws of this aggregated procedure and propose an adjusted (i.e. business segment-orientated) LI approach, which is then applied to assess the market power of banks in the specific lending business at the country level. Our empirical study is based on an original data set containing all interest-related categories (weighted by the respective loan as well as deposit volumes) in the countries of the European Monetary Union zone (EMU) from 2003 to 2013. Our results reveal that the country-specific market power of banks in the lending business has been substantially underestimated in previous studies based on aggregated outputs. For example, averaged across the five most important economies in the EMU, we detect a calibration factor of four. Our findings corroborate the economic notion that the interest-bearing lending business is a more locally separated, and thus profitable, segment in which competition is attenuated.     

转移成本、价格歧视与银行竞争——基于霍特林模型的实证分析

在银行业竞争中,转移成本能够锁定消费者,使银行能够对锁定的消费者定一个较高的价格,但是,转移成本也使银行对没有被锁定的消费者的竞争更加激烈。研究发现,转移成本的存在增加了银行的利润,并且转移成本越高,银行从信贷中获得的利润越高。但是,当存在存款市场和贷款市场竞争时,由于价格歧视的存在,银行的利润随着转移成本的增加而降低,转移成本没有给银行带来优势。     

寡头垄断、风险竞争与中小银行的发展困境:2001-2006

金融市场开放和改革使我国中小银行得到了较快发展,但也逐步陷入了风险扩张而绩效下滑的困境中.运用基于Stackelberg模型构建的寡头垄断市场银行风险竞争模型来对中小银行发展困境进行的实证研究发现,在资金价格(存贷款利率)受到严格管制的垄断市场中,银行间的竞争将会导致银行体系风险水平与资产规模的不断扩张,而不是经营绩效的持续提升.要使中小银行摆脱发展困境并得到健康发展,必须在培育银行业专业化分工的同时逐渐打破银行体系的垄断格局,推进利率市场化,放开对资金价格的严格限制,使中小银行的非价格竞争劣势转变为价格竞争优势;同时加强对中小银行的监管,为其营造一个公平竞争的市场环境.     

Product differentiation and welfare: Comment

In general it may be argued that the monopolistically competitive industry is not consistent as viewed from the game-theoretic point of view, and it ignores the strategic aspects of competition. This comment points out specifically how the welfare implications derived from a Nash equilibrium model in which the goods are imperfectly substitutes used by Spence in many articles are incorrect. The total quantities offered by firms at Nash equilibria within this model and those of the market demand curve at the same price levels are not equal. All emanate from the misspecification of the price equation with substitutable goods by Spence which is not appropriate for the Nash equilibria model with many firms. Moreover, some other very important papers of Spence which follow are critisized for the same mathematical contradiction.     

Enterprise restructuring and bank competition in transition economies

We investigate how bank competition affects the efficiency of credit allocation, using a model of spatial competition. Our analysis shows that bad loans are more likely the larger the number of banks competing for customers. We study further how many banks will be active if market entry is not regulated. Free entry can induce too much entry and thus too many bad loans compared to the social optimum. Finally we analyse how bank competition affects the restructuring efforts of firms. We find that restructuring has positive externalities which give rise to multiple equilibria, with either much or little restructuring activity.

Market structure and market performance in E-commerce

We analyze the interaction between market structure and market performance and how it varies over the product cycle. To account for the potential endogeneity in this relation, we use an instrumental variable approach. We combine data from the largest Austrian online market for price comparisons with retail data on wholesale prices provided by a major hardware producer for consumer electronics. Our results show that instrumenting is important for estimating the empirical effect of competition on the markup of the price leader. One more firm in the market is associated with a reduction of the price leader׳s markup which is equivalent to competition between existing firms for an additional 3 weeks in the product life cycle. Our results support search theoretic models and contradict models of monopolistic competition. Moreover our results support the existence of price dynamics over the product cycle. They also highlight the substitutability between newly innovated and old expiring technologies and how it varies with respect to competitors׳ and own brand innovations.     

Dynamic Model for Market Competition and Price Rigidity

This article presents a price floor model in which durability, unit costs and production period are factors in explaining price rigidity. This article elaborates that cost structure plays an essential role in resolving the inconclusive relationship between market concentration and price rigidity. When the industry is characterized by decreasing returns of scale, the degree of price flexibility decreases as market competition intensifies. The reverse is true when the industry exhibits increasing returns of scale. The factors that cause price rigidity also foster price adjustment asymmetry and price adjustment lag. During times of recession, the model exhibits upward price flexibility as costs increase, but downward price rigidity as costs decrease. Even under forward-looking expectations, the way in which firms adjust prices could look as though they have adaptive expectations. If price stickiness is a characteristic of market competition, then public policies determined by price level could be too drastic for firms in competitive markets.

Analysis of threshold cointegration with asymmetric adjustments in the Hong Kong grocery industry

High market concentration in the Hong Kong grocery industry has been prevalent over many years with the domination of a few large supermarket chains. However, no research has been conducted on the price dynamics between the supermarket and non-supermarket sectors to investigate whether the non-supermarket sector can impose competitive discipline on the dominating supermarket chains. We argue that standard cointegration tests cannot allow for transaction costs and distinguish whether the price co-movement is attributable to price competition or collusion. Our study therefore fills this research gap by adopting the threshold cointegration tests in a three-regime threshold vector error-correction model to account for the asymmetric price adjustment dynamics between supermarket and non-supermarket sectors of Hong Kong and evaluate the market power of the supermarket sectors in the presence of transaction costs. Our results favour the presence of cointegration between the supermarket and non-supermarket price indices with asymmetric adjustment dynamics. We interpret the results of statistically significant downward price adjustments in the outer-band regimes as the evidence of mutual price competition. Nevertheless, the supermarket sector has stronger market power than the non-supermarket sector, and therefore can sustain higher price level without inducing substantial competition pressures inside the neutral band.     

Price competition and the Bertrand model: the paradox of the German mobile discount market

We investigate the degree of price competition among telecommunication firms. Underlying a Bertrand model of price competition, we empirically model pricing behaviour in an oligopoly. We analyse panel data of individual pricing information of mobile phone contracts offered between 2011 and 2017. We provide empirical evidence that price differences as well as reputational effects serve as a signal to buyers and significantly affect market demand. Additionally, we find that brands lead to an increase in demand and thus are able to generate spillover effects even after price increase.
