Despite the introduction of sophisticated stock market indices, investors often trade portfolios of the flawed indices to change their exposure to the market. In this study, we show that these transactions cause significant mispricing in individual stocks, especially during periods of significant market movement. As an influential, albeit flawed, stock index, we focus on the Nikkei 225. We find index constituents that are excessively weighted on the index, experience buying (selling) pressure when the stock market surges (falls), and experience price corrections after such periods of change. In contrast, non-constituent stocks do not experience such trading pressure. 相似文献

This paper summarizes the results of personal exposure monitoring and estimates the risk from exposure to 18 volatile organic compounds compared with health criteria set by the US Environmental Protection Agency. In study 1, personal exposure levels and outdoor air concentrations were compared, and in study 2, personal exposure levels and the corresponding indoor air concentrations were compared. From these studies, it was concluded that personal exposure to volatile organic compounds depended markedly on indoor air quality and that handling of compounds increased personal exposure markedly. Risk estimations indicated that chloroform in tap water, benzene from cigarette smoke and p -dichlorobenzene from household insecticide needed caution. 相似文献

Safer firms receive funding from reputable venture capitalists and offer new securities underwritten by reputable investment banks. We offer a new explanation for these facts employing a moral-hazard model in which a firm and an agent are matched endogenously. More reputable agent's effort has a greater impact on output. Safer firm's output reflects the agent's hidden effort more accurately and therefore the agent's pay scheme tied with the output powerfully motivates her to exert effort. In equilibrium, a safer firm should be matched with a reputable agent since this combination allows to maximize effort of the reputable agent. 相似文献

To explicitly explain the cost-reducing effects of technical progress experienced by each firm, we assume that technical progress,
namely, the prevalence of particular equipment, can be expressed by a function of logarithmic physical capital. Regarding
the technology cost structure, we propose a modified dynamic cost function model that consists of the above equation, the
translog variable cost equation containing technical progress as one of the factors, and Euler equations with respect to physical
and research and development capital stocks. Using data on eight firms in the Japanese electric-furnace steel industry for
the period 1970–1998, the model was empirically validated using the generalized method of moments. An elasticity of production
cost with respect to technical progress showed a cost-reducing effect. This fact was influenced by the type of product and
the extent of each firm’s R&D. Also derived from this model is one reasonable phenomenon of business-cyclically changing the
use of endogenous capacity. This economic information supports the appropriateness of the above model, including the assumption
of transforming technical progress into an endogenous variable, and the methods of analysis. 相似文献

Is the gravity model as applicable to trade in intermediate inputs as it is to trade in final goods? One of the contributions of this paper is that we explicitly account for the dual nature of products that can be used as either intermediate inputs or final goods. We find that the structural gravity model performs extremely well for describing bilateral trade in final goods and in intermediate inputs. Moreover, this continues to hold even when we focus on a subset of countries in which intermediate inputs trade accounts for a growing share of trade, namely "Factory Asia." However, the gravity model may perform poorly due to model misspecification (i.e., exclusion of intranational trade) and/or sample selection, even after the model considers the dual nature of products. We demonstrate that the poor performance of the gravity model is not attributable to the large trade flow of intermediate inputs, which supports the continued use of the model as these trade flows continue to grow in importance worldwide. 相似文献

The authors discuss the changing character of production strategies and organizational arrangements at three leading Japanese automotive assemblers against a background of concern with the impact of work regimes upon employees. Innovations in production line organization are compared within and between the companies, and the argument advanced suggests that the attempt to ‘humanize’ work routines and procedures, by the leading company especially, has met with mixed results. Sornetimcs more ‘efficient’ technologies and forms of organization have been inhibited in the pursuit of ‘human-centred’ forms of work organization. Nevertheless, the article points up the considerable variations which exist both between and within Japanese companies and trade unions with respect to the understanding of the role played by labour. 相似文献

Few studies have investigated whether Japanese banks affiliated with bank holding companies are more efficient and profitable than independent banks. The present paper tests this hypothesis by using both a stochastic frontier approach and a market valuation approach. First, our results suggest that banks affiliated with bank holding companies are not more cost-efficient than are independent banks. Because of the brief history of Japanese BHCs, it is fair to conclude that the formation of regional bank holding companies has not achieved efficiency gains so far. Second, we find that banks affiliated with bank holding companies are more profit-efficient than are independent banks. This is particularly apparent when the establishment of the bank holding companies increases market power in regional markets. This supports the Financial Services Agency’s policy to increase the profitability of regional banks through bank consolidation. Finally, based on standard event study methodology, we find that the market did not regard news about the establishment of bank holding companies as significant events.JEL Classification: G21 相似文献

This paper utilizes micro‐panel data for firms located in Japan and examines differences in corporate performance between foreign‐owned and domestically‐owned firms in the 1990s. We find that foreign‐owned firms not only reflect superior static characteristics, but also achieve faster growth. Moreover, foreign investors appear to invest in firms that may not be immediately profitable, but those that are potentially the most profitable in the future. There is also no evidence that foreign investor is “foot‐loose.” These imply that foreign investors bring useful firm‐specific assets into the Japanese market, which may work as an effective catalyst for necessary structural reform. 相似文献
