This paper examines the implications of lag structure for estimating the effects of monetary policy shocks in a VAR. A symmetric lag structure in which all variables have the same lag length and an asymmetric lag structure in which the lag length differs across variables but is the same for a particular variable in each equation of the model are examined. This is important in light of the fact that the true lag structure is generally not known. Four commonly used identification schemes are employed to identify monetary policy shocks. Monte Carlo simulations strongly indicate that the lag structure of a VAR model does matter when assessing the quantitative effects of monetary policy shocks. Given the inherent uncertainty about the true lag structure in practice, it is thus important that one compare the impulse response functions from both symmetric lag and asymmetric lag VARs in assessing the effects of monetary policy shocks.  相似文献

The relationships among drug offenses, prorperty crime, and the allocation of police resources are investigated in a structural model using data from Florida countries. Law enforcement resources are scarce, and as efforts to combat drug crime increase the amount of these resources allocated to property crime is reduced. This reallocation of police resources results in reduced deterrence for property crime and, as a result, an increase in these crimes. The evidence presented suggests that rising property crimes in Florida are at least partially the result of drug enforcement policy.  相似文献

Preannouncements are strategic marketing communications directed at market participants including investors, suppliers, distributors, and buyers. Most empirical literature focuses on antecedents influencing a firm’s preannouncement behavior and on outcomes related to deleterious responses by competitors. This study differs and follows the large body of extant research that examines preannouncing behavior as a deliberate marketing communication process aimed at influencing market participants in the firm’s favor. The authors develop and test a model of preannouncement behavior that affects the success of a new product launch through market anticipation, competitive equity, and new product development resources. The findings indicate that preannouncement behavior engenders new product success through its positive effect on market anticipation—a favorable industry-wide bias in advance of new product introduction—and emphasizes the use of preannouncements as business-to-business marketing communications aimed at influencing current and prospective supply chain partners in the firm’s favor.

Conflicts remain an integral part in shaping the world. Tensions on the Korean Peninsula are no exceptions. The Korean DMZ (Demilitarized Zone) World Peace Park has been proposed to help obtain peace by erasing the memories of war and creating new beginnings of trust, cooperation, and unity on the Korean Peninsula. With their ties to geographical space and conflict, peace park research provides an excellent platform for both activism and research in positive peace. Little, however, is known about peoples’ willingness to pay (WTP) for the creation of peace parks, in general, and specifically for the development of the Korean DMZ World Peace Park. Using contingent valuation methods, the weighted average WTP for development of the Peace Park is $49.03 per household per year. It appears South Koreans are willing to pay not only for the conservation of the DMZ, but also for the peace and unification of the Korean Peninsula the Peace Park may bring to the area.  相似文献

This paper analyses the relation between money and inflation in Germany in a cost-push/demand-pull model of an open small economy by means of cointegration methods. The full-information-maximum-likelihood method of Johansen as well as structural methods are applied to datasubsets and the full data set. The focus of the paper is on tests for overidentifying restrictions and for weak and strong exogeneity within these data sets. The result of the paper is that the money stock, the price level and gross national product are endogenous whereas the interest rate and the real import price are both weakly and strongly exogenous. By means of the price cointegration relation we illustrate how monetary targeting should react to imported inflation.  相似文献

The firm dynamics literature has stressed productivity, size, and age effects in firm duration. Understanding the implications of financial state has largely been unexplored because of the lack of quality data on private entrant firms. This paper investigates the role of start‐up financial conditions (debt‐to‐asset ratio) on the duration of entrant manufacturing firms using a unique administrative firm‐level database called T2LEAP. The debt‐to‐asset ratio has an economically and statistically significant effect on firm hazard after controlling for usual covariates and unobserved heterogeneity. Further, a non‐monotonic relationship between firm hazard and leverage appears. Firm hazard varies positively with leverage for firms in the top two leverage quintiles, whereas hazard rates fall with leverage in the lower quintiles.

Recognizing policy-making process as a communicative process, this study examines who has subsidized information relating to the net neutrality policy debate. Empirical data has been collected from net neutrality stories published in four national newspapers, as well as from hearings by Congress and the Federal Communications Commission (FCC), during the period of February 2004 through January 2009. Study findings reveal that corporate interests have played a significant role in subsidizing information on net neutrality, both to the public through the mainstream media and to legislators through Congressional hearings. Furthermore, study results show that experts played a larger role in defining net neutrality through the mainstream media and FCC hearings than they did through Congressional hearings. Finally, the role of advocacy group representatives was more apparent at Congressional hearings than via the other two available information channels.  相似文献

Making decisions on strategic investments, such as early stage manufacturing technology (MT), is a complicated task. Early stage technologies are usually costly, and surrounded by uncertainty. The potential benefits are often hard to quantify prior to implementation. Thus, how could managers make good decisions in a high-risk, technically complex business when the information they need to make those decisions comes largely from the project champions who are competing against one another for resources? Traditionally, in this problem domain, decisions are made based upon gut-feeling and past experience, sometimes with the support of some multi-criteria decision-support tools. The criteria evaluation process is very subjective and relies heavily on managers’ experience, knowledge, as well as intuition. Thus, the evaluation approach is often not effectively carried out as there is lack of visibility and traceability in the decision making process. The impact of this scenario is that managers are not confident that resources are being optimised and applied to a mixed portfolio of projects to maximise benefits. This paper proposes a marginal analysis directed branch and bound approach for evaluating and selecting early stage manufacturing technology (MT) projects. A case study is used to demonstrate the application of the proposed approach. Implications of the proposed approach to practitioners and academia are discussed and future research outlined.  相似文献
