This article employs methodologies based on fractional integration and cointegration to analyse the time-series properties of merger and acquisitions (M&A) activity and crude oil prices in the US from 1980 to 2012. Our results indicate that an increase in the crude oil price produces a significant increase in the M&A data between 2 and 3 months after the initial shock.  相似文献

Comparing prospective data from the UK and Russia, this paper analyzes whether the association of labour market status, and particularly unemployment, with subsequent health varies by the level of state protection provided to the unemployed. While the UK's unemployment welfare regime is classified as providing minimal protection, the Russian regime is sub-protective. Employing Cox duration analysis upon data from the Russian Longitudinal Monitoring Survey and the British Household Panel Survey for the period 2000–2007, this study finds that labour market status and economic circumstances independently predicted individual-level declines in self-rated health and, contrary to expectations, the associations of unemployment with health decline were similarly sized in the two countries.  相似文献

A common procedure in economics is to estimate long-run effects from models with lagged dependent variables. For example, macro panel studies frequently are concerned with estimating the long-run impacts of fiscal policy, international aid, or foreign investment.Our analysis points out the hazards of this practice. We use Monte Carlo experiments to demonstrate that estimating long-run impacts from dynamic models produces unreliable results.Biases can be substantial, sample ranges very wide, and hypothesis tests can be rendered useless in realistic data environments. There are three reasons for this poor performance. First, OLS estimates of the coefficient of a lagged dependent variable are downwardly biased in finite samples. Second, small biases in the estimate of the lagged, dependent variable coefficient are magnified in the calculation of long-run effects. And third, and perhaps most importantly, the statistical distribution associated with estimates of the LRP is complicated, heavy-tailed, and difficult to use for hypothesis testing. While many of the underlying problems have been long-known in the literature, the continued widespread use of the associated empirical procedures suggests that researchers are unaware of the extent and severity of the estimation problems. This study aims to illustrate their practical importance for applied research.  相似文献

This paper demonstrates that the framing of post-war Kowloon Walled City through photos has been dominated by the maps commonly used to represent this Chinese enclave in colonial Hong Kong as a place. Inspired by and extending Wylie’s (2009) argument that emptiness and presence are equally important, this paper uses basic GIS techniques and hitherto unpublished archival materials to help (a) argues that the colonial government’s mindset of clearly defining the spatial boundary of the city, which is a subtle admission of an officially and diplomatically denied otherness in ownership, created the city as a quasi-cadastral unit; and (b) explains how this shaped the framing of the landscape of the city by promoting investment and trade in high-rise housing development units. The government did not destroy its walls. When these were physically destroyed, it did not ignore the walls’ original alignments but treated the city as a planning unit, as if they still existed.  相似文献

By using both macro‐ and micro‐level data, this paper investigates how wages and prices evolved during Japan's lost two decades. We find that downward nominal wage rigidity was present in Japan until the late 1990s, but disappeared after 1998 as annual wages became downwardly flexible. Moreover, nominal wage flexibility may have contributed to Japan's relatively low unemployment rates. Although macro‐level movements in nominal wages and prices seemed to be synchronized, such synchronicity is not observed at the industry level. Therefore, wage deflation does not seem to be a primary factor of Japan's prolonged deflation.  相似文献

Well-anchored inflation expectations are a key factor for achieving economic stability. This paper provides new empirical results on the anchoring of long-term inflation expectations in the euro area. In line with earlier evidence, we find that euro area inflation expectations have been anchored until fall 2011. Since then, however, they respond significantly to macroeconomic news. Our results obtained from multiple endogenous break point tests suggest that euro area inflation expectations have remained de-anchored ever since.  相似文献

Wheat yields from reported performance test results are of economic importance to wheat producers, since their profits depend on selecting the optimal variety for their location. However, our data shows differences in absolute and relative wheat yields between commercial and public wheat breeding program's performance test data in Kansas. Newly available data are used to test if the difference in yields arose from potential selectivity bias, and to determine the contribution of private and public wheat breeding programs to varietal yield improvement during 2007–2012. Both Heckman selection models and multiple regression showed no statistical evidence of the potential presence of selectivity bias rather, managerial practices, agronomic conditions, field location, and inherent genetic traits of the seed variety were identify as the source of yield differences.  相似文献

We analyze how a set of determinants affect trade among European countries over the period 1992–2008. The factors encompass variables from the areas of geography, culture, institutions, infrastructure, and trade direction. Trade is analyzed for four types of goods: primary goods, parts and components, capital goods, and consumer goods. For each type of good we also distinguish its definition in terms of flows, intensive margin, and extensive margin. Methodologically, we first derive country-pair fixed effects over all possible pairs of export–import partners, and in the second stage we relate fixed effects with a set of influential factors. We show (i) the intuitive and varying effects of geographical, cultural, and institutional factors; (ii) the beneficial effects of soft and hard infrastructure; and (iii) the key importance of trade between old and new EU members.  相似文献

Alcoholic beverages represent both an important source of revenue and a driver of expenditure for provincial governments in Canada. As a result, the pricing of alcoholic beverages has substantial public policy implications. In this context, we re-examine existing work estimating the demand for three classes of alcoholic beverage (beer, wine, and spirits) by controlling for common correlated effects. The results reveal that any conclusions regarding the government’s ability to influence alcohol consumption is sensitive to the assumption that the relationship between the demand for alcoholic beverages and economic variables is identical across provinces.  相似文献
