This study attempts to investigate market power in the U.S. commercial banking industry since the U.S. government began to deregulate the banking sector in the early 1990s using the static Bresnahan–Lau model (SBLM) and dynamic Bresnahan–Lau model with error corrections (DBLEC). In particular, panel unit root and panel cointegration techniques are utilized to examine the dynamic model. The empirical results of the SBLM show that the banking industry is highly competitive. The empirical results of DBLEC also suggest that the commercial banking industry is close to being perfectly competitive in the short run. By contrast, the adjustment speeds of the supply and demand sides towards the long-run equilibrium are quite slow in that market, which implies that the U.S. commercial banks enjoy a certain degree of long-run market power. 相似文献

Revised implied volatility curves and surfaces for the Chinese Yuan (CNY) exchange rate are obtained from market quotations for CNY non-deliverable options by solving an inverse problem of foreign exchange option pricing, which is calculated using a regularization approach in an optimal control framework. To take account of the market expectation for the CNY exchange rate, a stochastic adjusted factor is applied that follows a Vasicek model with parameters fitted from market quotations for CNY non-deliverable forwards. A well-posed numerical scheme is implemented. 相似文献

市场分割条件下的混合所有制经济竞争模型与规制策略 总被引:1,自引:0,他引:1
通过构建市场分割条件下的混合所有制经济竞争模型,本文对全国性国有企业在中国改革发展过程中的作用提供了新的解释。全国性国有企业在参与区域竞争的过程中,具备一种区域整合的功能:它面向全体市场的决策与分别面向各区域市场的决策等价,全社会总剩余最大化目标也可以分解为各区域社会剩余最大化的子目标之和,在其效率较高的情况下,将迫使地方企业改进成本或者退出市场,而只有当地方企业有足够高的效率的时候,全国性国有企业才会选择退出策略。国有企业事实上可以作为一种内部规制工具对市场分割的负面效应进行一定程度的制衡,在明确规制规则的条件下,我们可以通过动态调整企业目标函数以实现整体市场福利的最大化。 相似文献

基于劳动力、产业在地区间分布的不平衡性以及地区间工资差异的事实,本文构建了一个市场潜力与工资的新经济地理学(NEG)理论模型。理论分析表明:市场潜力对工资产生正面影响。市场潜力对工资产生正面影响来自两种渠道:一是市场潜力引发了经济集聚效应;二是市场潜力产生了逆经济集聚。相比之下,市场潜力引发了经济集聚效应更能提高和扩大地区工资水平与差异,因为经济集聚需要更低的贸易成本、较大的市场规模以及较高的经济发展水平。 相似文献

国有企业、金融市场改革与养老保险制度改革的互动效应--中国如何解决老年保障问题? 总被引:5,自引:0,他引:5
中国政府非常清楚社会保障所面临的危机,决定寻求解决办法。拟议中的社会保障改革的核心是积累制和整合条块分割的体系,计划为每个工人建立个人退休账户,对养老基金进行有效投资。然而,这种改革受阻于三个关键因素。(1)在向积累制的转化过程中必须支付特制成本;(2)现有的社会保障体系条块分割、分散化管理3(3)已经积累的基金尚未取得高收益,也未分配到最有效率的用途上。 相似文献

Economic geography and wages in Brazil: Evidence from micro-data 总被引:1,自引:0,他引:1
Thibault Fally Rodrigo Paillacar Cristina Terra 《Journal of development economics》2010,91(1):155-168
This paper estimates the impact of market and supplier access on wage disparities across Brazilian states, incorporating the control for individual characteristics into the new economic geography methodology. We estimate market and supplier access disaggregated by industry, and we compute access to local, national and international markets separately. We find a strong correlation between market access and wage differentials, even after controlling for individual characteristics, market access level (international, national or local), and using instrumental variables. 相似文献

The balance of payments is an accounting identity. Many wonder how the current and capital accounts, which add up to zero, can influence exchange rates. This paper shows how payment flows arising from balance of payments imbalances affect the demands for different currencies in the foreign exchange market over time. Based on a dynamical system approach, the paper demonstrates how international payments evolve depending on the joint dynamic behaviour of different balance of payments components. It finds that international payments and exchange rates interact in fundamentally different ways depending on whether a country restricts its capital inflows and outflows, whether capital flows are accommodating or autonomous and whether the exchange rate is fixed, flexible or, say, governed by a crawling peg. Empirical evidence from major industrial countries as well as from countries hit by currency crises support the paper's theoretical predictions. 相似文献

We investigate how investors should optimally choose to invest in a dynamically complete international market. We find closed-form solutions for the optimal investment strategy and for the wealth loss an investor suffers from not investing internationally. Theoretically, we show that the gain from international investment is due to the speculative investment only, and why it is important for an investor from a large economy to invest in a small economy. In a numerical example we compare the wealth losses investors from Denmark and the U.S. suffer due to home bias. 相似文献

审计师行业专长对审计收费的影响分析——来自2006~2007年我国审计市场的证据 总被引:1,自引:0,他引:1
杨继飞 《中南财经政法大学学报》2010,(1)
本文在借鉴传统审计收费模型的基础上,采用我国A股上市公司2006~2007年的数据,对审计师行业专长与审计收费之间的相关关系进行实证分析.研究表明,我国的审计师行业专长程度较低,审计师行业专长与审计收费之间存在正相关关系.研究审计师行业专长与审计收费之间的关系对于规范审计定价行为、形成有效市场结构有重要意义. 相似文献

This paper describes and analyses changes at the concentration level of the audit services markets in 15-EU member-countries.
The sample consists of 2,862 clients of auditing firms for the period 1998 to 2004. The findings of the research show that
concentration in the aggregate sample increased over time. Concentration in the audit markets of the EU-15 member-countries
exhibits substantial variation across countries while average concentration, before and after Arthur Andersen’s dissolution,
has increased in 12 and declined in three countries. Results segmented by economic sectors indicate that the concentration
increased in all sectors except Energy, which is the sector with the highest concentration. Overall, the empirical results
suggest that there are complexities in our understanding of auditing services markets for competition purposes.
