贷款准备金政策框架下的区域货币政策独立性

美国次贷危机引发这轮全球性金融危机凸显了以美国为核心的金融资本主义模式和以美元为核心国际货币金融体系的制度性缺陷,改革现行以美元为核心的国际货币金融体系势在必行,建立货币区是较为现实的选择。但在现行货币政策框架下,货币区建设不可避免会陷入三元悖论困境。本文提出在贷款准备金政策框架下,货币区能在保证其内在要求的资本自由流动和汇率稳定基本前提下,区内各个成员仍能保持货币政策独立性。     

外汇市场压力问题的研究综述

本文从外汇市场压力的测度、外汇市场压力与货币政策、外汇市场压力与货币危机的识别与测度以及外汇市场压力与汇率制度四个方面总结了国外研究者对此的最新研究成果,从中我们发现外汇市场压力对于一国经济有着重要的影响,特别是在当前通胀预期下,外汇市场压力与我国资产价格波动和货币政策之间的相互作用过程值得我们去进一步研究。     

Industry Structure and Corporate Debt Maturity

We examine how industry competition affects firms’ choice of short‐term debt. We find that the percentage of short‐term debt is positively related to industry concentration at low levels of concentration, and inversely related to industry concentration at higher levels of concentration. This nonlinear relation is stronger in industries where firms are either more homogeneous or compete more aggressively. Moreover, we find that firms with shorter‐maturity debt are less aggressive than their rivals in the product market. The overall evidence suggests that although financial contracts alleviate agency problems, they exacerbate the risk of predation.     

Crowding,satiation, and saturation: The days of television series' lives

The performance of firms depends not just on the structure of the industries in which they compete but also on their relative positioning within those industries, in terms of operating within particular niches. We propose that demand for these niches depends endogenously on the historical ecology of the products offered: Niches become saturated—reduced in their ability to support products—as a large number of previous offerings allows the audience to satisfy its desire for products of a particular type. Analyzing the survival rates of television series aired in the United States from 1946 to 2003, we found that the survival rates of future entrants fell with the extensiveness of recent offerings in the niche, and that the negative association between crowding and survival also weakened with this saturation.

Innovation ecosystems and the pace of substitution: Re‐examining technology S‐curves

Why do some new technologies emerge and quickly supplant incumbent technologies while others take years or decades to take off? We explore this question by presenting a framework that considers both the focal competing technologies as well as the ecosystems in which they are embedded. Within our framework, each episode of technology transition is characterized by the ecosystem emergence challenge that confronts the new technology and the ecosystem extension opportunity that is available to the old technology. We identify four qualitatively distinct regimes with clear predictions for the pace of substitution. Evidence from 10 episodes of technology transitions in the semiconductor lithography equipment industry from 1972 to 2009 offers strong support for our framework. We discuss the implication of our approach for firm strategy. Copyright © 2015 John Wiley & Sons, Ltd.

Measuring DEA efficiency in cable television network facilities: what are appropriate criteria for determining the amounts of governmental subsidies?

Recent technological developments have transformed the cable television industry (CATV) from a simple re-transmitter of terrestrial broadcasting to a provider of a broader-band information infrastructure. With cable operators facing an undesirable market situation while operating a fiber optics network vital to the creation of an information-based society within Japan, the Japanese Government has introduced several supportive measures for the industry. Such governmental intervention should desirably be justified not only from a political viewpoint but also from an economic one; otherwise such measures may distort economic efficiency. In this article, using Data Envelopment Analysis (DEA), the authors identify the deficiencies of an accounting-based intervention scheme and propose an alternative framework with no disincentive side effects.     

Banks' environmental policy and business outcomes: The role of competition

By integrating the two areas of competition–performance and environment–performance, this research explores if competition matters in the relationship between environmental practices and interest margins in the market. A panel of 458 banks from 74 countries for the period of 2006–2016 is used, and the sample is further divided into developed and developing countries. This paper uses the system Generalized Method of Moments estimator to tackle potential omitted variable bias, endogeneity, and simultaneity issues. Without competition, environmental practices only affect banks in developing countries; however, the results show a significant impact for the full sample, including developed countries, when the competition is taken into consideration, suggesting that competition might play a role in the relationship of environmental practices and interest margins. In the full sample, competition impacts the relationship negatively after a moderate level of competition is reached in the market. The environmental practices in developing countries are prone to competition in the market. In developed countries, the competition is found to be lightly positively moderating the impact of environmental practices on interest margins. Based on these findings, it is recommended that developing countries should have a low or moderate level of competition to encourage environmental practices. For developed countries, however, high competition should be preferred to encourage banks to consider environmental practices as one of their core business strategies. These findings are found robust to different statistical estimators.     

On the predictability of the distribution of excess returns in currency markets

This paper investigates the predictability of foreign exchange (FX) volatility and liquidity risk factors on returns to the carry trade, an investment strategy that borrows in currencies with low interest rates and invests in currencies with high interest rates. Previous studies have suggested that this predictability could have been spuriously accounted for due to the persistence of the predictors. The analysis uses a predictive quantile regression model developed by Lee (2016) that allows for persistent predictors. We find that predictability changes remarkably across the entire distribution of currency excess returns. Predictability weakens substantially in the left tail once persistence is accounted for, implying a moderate negative predictive relation between FX volatility risk and carry trade returns. By contrast, it becomes stronger in the right tail. Furthermore, we provide evidence that FX volatility risk still dominates liquidity risk after controlling for persistence. These findings suggest that the persistence of the predictors needs to be taken into account when one measures predictability in currency markets. Finally, out-of-sample forecast performance is also presented.     

基于消费者绿色偏好的异质产品竞争的两级供应链研究
