This paper examines the interrelationship between stock prices in the US and Korea by applying the vector autoregression (VAR) model to the daily stock prices at three different level of aggregation – the national aggregate index level, the high-tech industry level and the semiconductor firm level – for the period of July 1996 through February 2001. The major findings of this study are as follows. First, the US stock market plays a leading role over the Korean market at every level of aggregation. The reverse direction of influence, from Korea to the US, was found to be minimal. Second, the evidence also suggests that the speed of transmission of innovation from the US to Korea is swift and finished for the most part within a 24-h period, although it takes three or four days to complete the whole process. Third, the influence of the US stock prices on Korean stock prices, which is measured by the innovation transmission using the impulse–response function (IRF) analysis, seems to be somewhat stronger in the composite national stock price indices and the tech-laden indices than high-tech firms. Fourth, at the firm level, the influence of Micron Technology on the leading semiconductor manufacturers in Korea is shown to be strong and persistent by passing about 34 percent of its innovations to the Korean firms within the three-day period. The impact of IBM and Intel on the Korean chip makers seems to be relatively smaller. Finally, stock prices in Korea, national stock price indices and individual high-tech stocks alike, have become much more responsive to innovations in the US stock prices after the 1997 financial crisis. The implications of the main findings in this paper are also discussed. 相似文献

制造业企业的技术发展离不开适宜类型的金融支持。那么,我国以商业银行为主导的金融体系对其具有怎样的影响?本文从技术距离视角出发,通过构建熊彼特内生增长模型探究银行主导型金融体系对制造业企业技术进步的影响效应及作用机理,并运用中国工业企业数据库与城市数据库的匹配数据进行实证检验。研究发现:当制造业企业远离技术前沿时,银行主导型金融对其技术进步具有明显的促进作用,但随着企业接近技术前沿,该作用将由正转负。相较于国有和抵押资产丰富的制造业企业,银行主导型金融对技术进步的负向作用在非国有和抵押资产匮乏企业中出现较早。机制检验表明,在远离技术前沿阶段,银行主导型金融能够激励制造业企业创新从而促进其技术进步,但在接近技术前沿后,银行主导型金融难以通过激励企业创新驱动其技术进步。研究结论对如何深化金融供给侧结构性改革、增强金融服务制造业之功效具有一定的指导意义。 相似文献

For rural households in the north of Vietnam, maize cropping is the main source of income. In the face of the world market price increases of the recent past, we analyze the regional marketing chain of this commodity qualitatively and econometrically investigating to what extent smallholder farmers in developing countries are affected by international price movements. Vietnamese maize markets are found to be well integrated. Recent price hikes have fully transmitted along the regional supply chain so that farmers profited. Nevertheless, adverse factors such as increasing input prices have neutralized these benefits resulting in a decline in real income of smallholders. 相似文献

Sources of exchange rate fluctuations: Are they real or nominal? 总被引:1,自引:0,他引:1
Luciana Juvenal 《Journal of International Money and Finance》2011,30(5):849-876
I analyze the role of real and monetary shocks on exchange rate behavior using a structural vector autoregressive model of the US vis-à-vis the rest of the world. The shocks are identified using sign restrictions on the responses of the variables to orthogonal disturbances. These restrictions are derived from the predictions of a two-country DSGE model. I find that monetary shocks are unimportant in explaining exchange rate fluctuations. By contrast, demand shocks explain between 21% and 37% of exchange rate variance at 4-quarter and 20-quarter horizons, respectively. The contribution of demand shocks plays an important role but not of the order of magnitude sometimes found in earlier studies. My results, however, support the recent focus of the literature on real shocks to match the empirical properties of real exchange rates. 相似文献

Recent frauds have questioned the efficacy of the SEC's enforcement program. We hypothesize that differences in firms' information sets about SEC enforcement and constraints facing the SEC affect firms' proclivity to adopt aggressive accounting practices. We find that firms located closer to the SEC and in areas with greater past SEC enforcement activity, both proxies for firms' information about SEC enforcement, are less likely to restate their financial statements. Consistent with the resource-constrained SEC view, the SEC is more likely to investigate firms located closer to its offices. Our results suggest that regulation is most effective when it is local. 相似文献

This paper assesses the contemporary relevance of distance and its key components in international business for young, internationally-oriented small firms. In doing so, it reconceptualizes the distance concept and investigates its relevance in American, British, and German firms' early foreign market selection. Economic, geographic, and cultural distance (based on Hofstede's and Schwartz's frameworks) for the three countries, along with psychic distance for the German firms, are considered. The results show that some components of distance still matter for internationally-oriented small firms and that cultural distance is sample source and concept sensitive. In addition, psychic distance acts as a mediator construct to the more objective, external distance measures of economic, geographic, and cultural distance, confirming the proposed distance framework. 相似文献
