Late nineteenth–century Canada attracted a large number of immigrants from the UK, despite far lower average income per head there than in the US. While urban labour markets in the northern US were much larger than those in Canada, differences in outcomes between UK immigrants in Canadian and in northern US cities were small. Average annual real earnings by occupation group were only 10 to 15 per cent lower in Canadian cities. Individual–level census data indicate that the occupational distribution of UK immigrants in Canada was quite similar to that of their peers in the US. 相似文献

I show that historical cashflow volatility is negatively related to future returns cross-sectionally. The negative association is large; economically meaningful; long-lasting up to five years; robust to known return-informative effects of size, value, price and earnings momentums and illiquidity; and extends to both systematic and idiosyncratic cashflow volatilities. Using the standard deviations of cashflow to sales and of cashflow to book equity as proxies for cashflow volatility, the least volatile decile portfolio outperforms the most volatile decile portfolio by 13% a year relative to the Fama–French four factors. The cashflow volatility effect is closely related to the idiosyncratic return volatility effect documented in Ang et al. [Ang, A., Hodrick, R.J., Xing, Y. and Zhang, X. “The cross-section of volatility and expected returns.” Journal of Finance, 51 (2006), 259–299.]. However, in portfolios simultaneously sorted on both cashflow and return volatilities, and in cross sectional regressions of returns at the firm level, these two effects neither drive out nor dominate each other. While the pricing of idiosyncratic cashflow volatility represents an anomaly against the traditional asset pricing theories, the pricing of historical cashflow uncertainty sheds light on potential fundamental risks embodied in the Fama–French HML and SMB factors. 相似文献

Abstract: This paper conducts a UK test of a version of the Ohlson (1995) model. We should only expect abnormal earnings to revert to zero if the book value of assets is economically meaningful. In this paper we make use of the property revaluations common in UK accounts, but estimate other asset values and earnings in inflation‐adjusted terms. This, we argue, gives rise to estimates of abnormal earnings that can reasonably be expected to revert to zero. We then test this modified model on UK data using the Dechow, Hutton and Sloan (1999) method. In line with the predictions of the Ohlson model, we find that these modified abnormal earnings appear to mean revert, and that a first order autoregressive process is sufficient to capture the persistence of UK real abnormal earnings. The modified abnormal earnings model in general predicts one year ahead earnings more successfully than an unmodified model. Furthermore, for much of the sample period, one year ahead predictions of abnormal earnings are better for the real model during periods of higher inflation. The undervaluation problem found in prior studies appears to be replaced with an overvaluation problem in the real model which is more acute during periods of high inflation. Last, we show that an estimate of the model based upon an industry level specification appears to perform no better than a market‐wide specification of the model. 相似文献

Testing for non-linear dependence in inter-war exchange rates 总被引:1,自引:0,他引:1
Testing for Non-Linear Dependence in Inter-War Exchange Rates. — This paper tests weekly inter-war floating exchange rate data for the pound-dollar, pound-franc and pound-reichsmark for non-linearity. Initial tests reveal strong evidence of generic non-linearity in these series and indicate neglected non-linear structure in the residuals of linear representations. Attempts to model this structure using GARCH residual processes have only been partially successful. Thus, two parametric models of such non-linearity were estimated. Comparing the forecasts from these models shows the mean square forecast errors of linear-GARCH and bilinear models to be lower than those from linear forecasts for all series, and that SETAR model forecasts outperform all other models for the pound-dollar. 相似文献

Many studies highlight the challenges facing incumbent firms in responding effectively to major technological transitions. Though some authors argue that these challenges can be overcome by firms possessing what have been called dynamic capabilities, little work has described in detail the critical resources that these capabilities leverage or the processes through which these resources accumulate and evolve. This paper explores these issues through an in‐depth exploratory case study of one firm that has demonstrated consistently strong performance in an industry that is highly dynamic and uncertain. The focus for the present study is Microsoft, the leading firm in the software industry. The focus on Microsoft is motivated by providing evidence that the firm's product performance has been consistently strong over a period of time in which there have been several major technological transitions—one indicator that a firm possesses dynamic capabilities. This argument is supported by showing that Microsoft's performance when developing new products in response to one of these transitions—the growth of the World Wide Web—was superior to a sample of both incumbents and new entrants. Qualitative data are presented on the roots of Microsoft's dynamic capabilities, focusing on the way that the firm develops, stores, and evolves its intellectual property. Specifically, Microsoft codifies knowledge in the form of software “components,” which can be leveraged across multiple product lines over time and accessed by firms developing complementary products. The present paper argues that the process of componentization, the component “libraries” that result, the architectural frameworks that define how these components interact, and the processes through which these components are evolved to address environmental changes represent critical resources that enable the firm to respond to major technological transitions. These arguments are illustrated by describing Microsoft's response to two major technological transitions. 相似文献

From 1948 to 1994, the agricultural sector was afforded special treatment in the GATT. We analyse the extent to which this agricultural exceptionalism was curbed as a result of the GATT Uruguay Round Agreement on Agriculture, discuss why it was curbed and finally explore the implication of this for EU policy making. We argue that, in particular, two major changes in GATT institutions brought about restrictions on agricultural exceptionalism. First, the Uruguay Round was a ‘single undertaking’ in which progress on other dossiers was contingent upon an outcome on agriculture. The EU had keenly supported this new decision rule in the GATT. Within the EU this led to the MacSharry reforms of the Common Agricultural Policy (CAP) in 1992, paving the way for a trade agreement on agriculture within the GATT. Second, under the new quasi‐judicial dispute settlement procedure, countries are expected to bring their policies into conformity with WTO rules or face retaliatory trade sanctions. This has brought about a greater willingness on the part of the EU to submit its farm policy to WTO disciplines. 相似文献

The paper addresses the application of foresight to research and innovation policy and strategy. It seeks to show an evolution away from a traditional focus on broad-based technological priority setting to a much more focussed and adapted set of applications. The inherent limitations of prioritisation processes are discussed. The more limited aim of articulating specific fields is noted. Recent trends in research and innovation policy have opened new opportunities for the application of foresight. Systemic and demand-side policies require a shared vision on the part of purchasers and suppliers. The role of foresight in such contexts needs both to be enhanced and better understood.An increasing structural focus for foresight exercises is associated not only with broader R&I system reform but also with an engagement with new-wave innovation policies. The success of demand-side measures such as cluster policies and the use of procurement or regulation to stimulate innovation is dependent upon the formation of a common vision between the supply and demand sides, opening the possibility for the application of foresight approaches. We note the emergence of a combination of corrective, disruptive and creative roles. 相似文献
