This paper explores the direct effects and spillovers of unconventional monetary and exchange rate policies. We find that official purchases of foreign assets have a large positive effect on a country’s current account that diminishes considerably as capital mobility rises. There is an important additional effect through the lagged stock of official assets. Official purchases of domestic assets, or quantitative easing (QE), appear to have no significant effect on a country’s current account when capital mobility is high, but there is a modest positive impact when capital mobility is low. The effects of purchases of foreign assets spill over to other countries in proportion to their degree of international financial integration. We also find that increases in US bond yields are associated with increases in foreign bond yields and in stock prices, as well as with depreciations of foreign currencies, but that all of these effects are smaller on days of US unconventional monetary policy announcements. We develop a theoretical model that is broadly consistent with our empirical results and that highlights the potential usefulness of domestic unconventional policies as responses to the effects of foreign policies of a similar type.  相似文献

Economists at the Federal Trade Commission pursue the agency??s competition and consumer protection missions. In this year??s essay, in antitrust, we discuss two recent mergers that involved Rx drugs: First, we describe key elements of the inquiry into the Express Scripts/Medco transaction in the pharmacy benefit management industry. Next, we analyze a merger that involved drugs that are used to treat patent ductus arteriosus: a condition that affects premature babies. On the consumer protection side, we discuss a pricing strategy??drip pricing??that involves the release of price information about a multi-part product over time as the consumer goes through the purchase process.  相似文献

In many social and economic situations the optimal solution requires the formation of coalitions that partition the set of players. When the individual player is small relative to the size of the existing coalitions, it seems realistic to assume that the prevailing coalition structure dictates the set of possible blocking coalitions. Specifically, it is assumed that an individual does not consider forming any coalition, but rather joining an already existing one. Two solution concepts for these games are investigated: structural equilibrium and stable payoffs, which are derived from the application of ψ-stability to the core and to the bargaining set, respectively. To this end an extension of the bargaining set to games without side payments is offered. Both solution concepts are shown to exist for some coalition structure. However, while structural equilibrium may fail to exist for any non trivial coalition structure, for every coalition structure there exists a stable payoff.  相似文献

This paper contrasts different policy assignments for central bank operations. Two types of asset market transactions (domestic, foreign) and two policy targets (interest rate, exchange rate) are examined within a portfolio-balance model. It is demonstrated that assigning domestic asset transactions to the internal target, and foreign asset transactions to the external target, produces stable policy paths, while the opposite assignment does not.

This paper is a study of the perceptions of young adults in the U.S. and China on the relations between the two nations. We conducted a case study by distributing a 17 question survey to 201 American undergraduate students (NYC) and 164 Chinese undergraduate students (Shanghai). The questions probed their views of U.S. and China’s economic and political systems, the future economic growth and political power in the world of the two nations, and the future political and economic relations between the two powers. The results of our study reveal a number of important perceptions that both U.S. and Chinese students have, some being similar and others being in sharp contrast. Most students in both countries view future political and economic relations between the U.S. and China predominantly as cooperative but only based on each nation’s self-interests. Both Chinese and American students agree that China is gaining political strength and economic influence among the advanced and the emerging nations of the world. While most of the U.S. students believe that China has been and will continue to grow at a much faster rate than the U.S., Chinese students are more likely to believe that this rate of growth is unsustainable. The results from our survey are compared and contrasted to the findings of national surveys for both countries. We believe that the study provides valuable insights into the similarities and differences in viewpoints of the next generation of adults in both nations about future U.S.-China relations.  相似文献

Policymakers advocating for later school starting times argue that increased sleep duration may generate important schooling benefits. Using data from the National Longitudinal Study of Adolescent Health, this study examines the relationship between sleep duration and academic performance, while carefully controlling for difficult‐to‐measure characteristics at the family and individual levels. We find that increased sleep time is associated with improvements in classroom concentration as well as increased educational attainment. However, we also find evidence of diminishing returns to increased sleep. We estimate an “academic optimum” number of sleep hours of, on average, 8.5 hours per night. Turning to sleep quality, we find that the onset of insomnia‐like symptoms is associated with diminished contemporaneous academic concentration, but little change in long‐run educational attainment.

Three decades ago, planned obsolescence was a widely discussed ethical issue in marketing classrooms. Planned obsolescence is topical again today because an increasing emphasis on continuous product development promotes shorter durables replacement and disposal cycles with troublesome environmental consequences. This paper offers explanations of why product obsolescence is practiced and why it works. It then examines the ethical responsibilities of product developers and corporate strategists and their differing responses to this problem. Pro-environment product design and marketing practices and innovative government policies may alleviate the problem over time. However, given the current lack of understanding about consumer replacement and disposal behavior, it is questionable as to whether these practices and policies will be sufficiently informed to be effective. Thus, marketing scholars have a significant opportunity to contribute to sustainable durables product development.  相似文献

This study examines the information content of model‐free implied volatility (MFIV) estimates with respect to the options and futures markets in Hong Kong. In this study, the volatility forecasting performance of MFIV is compared, using different prediction horizons, to IV estimates based on Black's futures option pricing model (BIV) and time‐series forecasts based on historical volatility (TS‐HV). The results show that the BIV prediction is unbiased for different horizon forecasts. MFIV outperforms TS‐HV forecasts and, most importantly, BIV subsumes the information content of both MFIV and TS‐HV forecasts. The results are largely maintained for next‐day forecasts but the forecasting quality of the two IV measures declines as expiration day approaches. The information contents of MFIV and TS‐HV forecasts are complementary. © 2012 Wiley Periodicals, Inc. Jrl Fut Mark 32:792‐806, 2012  相似文献
