Back to Basics: Forecasting the Revenues of Internet Firms 总被引:1,自引:0,他引:1
This paper examines the roles played by past revenues, web usage data, and analysts in forecasting the future revenues of internet firms during the years 1998 to 2000. For this time period our analysis shows that estimates of web traffic growth have significant incremental value in the prediction of revenues above time-series forecasts. Furthermore, analysts almost always underestimate the revenues of internet firms. Historical revenue growth has incremental predictive power over analysts' forecasts for portal and content/community firms, but not for our e-tailer sample. Moreover, the stocks of the portal and content/community firms with high historical revenue growth earn higher abnormal returns during our sample period than do those with low historical growth. Estimates of web usage growth generally do not have incremental value over analysts' forecasts for predicting the revenues of either set of firms. However, perfect foreknowledge of actual web usage growth would provide incremental predictive power. Collectively, our findings point to the potential value for forecasting purposes of both improving upon the web usage estimates and obtaining more timely reports of actual web traffic. 相似文献

The purpose of this paper is twofold. First, we discuss the nature and quantitative order of magnitude of the trade-off between real wages and employment in the small open economy Belgium. Second, we draw policy conclusions from our positive analysis, and compare income policies with alternative approaches to employment stimulation (including shorter working hours and currency depreciation).To study the trade-off between real wages and employment, we treat external balance as a binding constraint on demand management. An exogenous increase in real wages, affecting adversely the competitiveness of domestic producers on the export and import markets, impairs external balance. The impact of the wage increase on output and employment is evaluated through the reduction in domestic demand required to restore external balance.At the empirical level, we endeavour to evaluate separately the influence on exports and imports of domestic costs at unchanged capacity levels, and of capacity levels themselves. And we endeavour to evaluate the influence of real wages on capacity levels through scrapping and investment. All evaluations rely on the foreign trade equations of econometric models of the Belgian economy.The conclusions from our empirical investigation are first that estimates of the trade-off between real wages and employment in Belgium are subject to considerable imprecision; second that the short-run elasticity of employment with respect to real wages keeping capacity constant is probably quite small (like -0.2), and definitely less than unity in absolute value; third that the corresponding medium-run elasticity taking into account capacity adjustments is probably sizeable (like -2), and definitely larger than unity in absolute value; and fourth that exchange rate adjustments might not make too much difference, in either the short run or the medium run.Turning to a discussion of policy, we shall argue that these conclusions give support to a policy of constant real labour incomes, of comprehensive efforts to redistribute work through shorter working hours or related schemes, and of selective efforts to slow down capacity scrapping. 相似文献

This paper conducts an empirical analysis of the demand for money in Italy using data for the period 1867–1965. It finds that during this time this demand was a stable function of two key variables: permanent income and the rate of interest. 相似文献

This article provides an overview of the main traits of the historical development of the pharmaceutical industry, using the lenses of the evolutionary approach to economic and industrial change. After a brief overview of the main evolutionary concepts which guide the subsequent discussion, our presentation identifies four main eras: from the formative stages (from the late 1800s to War World II) to the so-called Golden Age (the 1940s to the mid-1970s), the biotechnology revolution (the 1970s to the new millennium, approximately) and what we label the ‘Winter of Discontent?’ (the first decade of the new century). Within all these epochs, we discuss the main trends in technology, firms' strategies and structures, patterns of competition, demand, regulation and institutional developments. Section 6 concludes the article, briefly discussing some main implications for the present and future of the industry on the one hand and for the relevance of an evolutionary approach to the analysis of corporate and industrial change on the other. 相似文献

We question whether the international diversification of multinational banks creates or destroys shareholder value. Based on a sample of 384 listed banks from 56 countries we provide new and robust evidence that bank cross‐border activities create shareholder value, as shown by an economically and statistically significant premium for international diversification. Our results are confirmed controlling for bank fixed effects, time‐varying bank characteristics, reverse causality, functional diversification, and instrumenting for the choice to expand abroad. The increase in shareholder value is slightly larger for banks in the middle range of international diversification and in the case of expansion towards less developed countries. 相似文献

The architectural style of next generation technological platforms intended to support design, deployment, and execution of
extended business processes inside organizational networks, must be guided by interoperability principles at the processes,
services, or data level. Service-oriented architectures, these being design patterns, and not merely technology, attempt to
address these issues. Yet we believe that some of their underlying concepts (i.e., service providers, interfaces, and instances)
must still be included at the business models level. This study attempts to show that how by introducing the Abstract and
Concrete Service Entities concept at the extended business process models level, it could be possible to address most of the
current interoperability issues inside a manufacturing network. 相似文献

Between 2000 and 2009, nine plant clinics in three agro-ecological areas of Bolivia (Andes, lowlands and valleys) served about 800 communities in an area roughly 300 × 100km. Over 6000 farmers consulted these clinics with 9000 queries. Many found the advice so useful that they visited the clinics repeatedly. A survey of 238 clinic users found that most adopted the clinics' recommendations. Fruit and vegetable growers who followed the clinic recommendations tended to spend less on pesticides. As for certain crops like potato, citrus and peach palm, a modest increase in pesticides helped improve the quality and quantity of the harvest. Farmers improved their incomes by following the clinics' advice. The poorest farmers enjoyed the greatest increase in income per hectare. This was the first study to explore the impact of plant clinics; future studies need to be improved, for example by obtaining baseline data and by comparing clinic users to their peers who have not used clinics. 相似文献

How does competition affect the investment banking business and the risks individual institutions are exposed to? Using a large sample of investment banks operating in seven developed economies over 1997–2014, we apply a panel VAR model to examine the relationships between competition and risk without assuming any a priori restrictions. Our main finding is that investment banks’ higher risk exposure, measured as a long‐term capital‐at‐risk and return volatility, was facilitated by greater competitive pressures for both boutique investment banks and full‐service investment banks. Overall, we find some evidence that more competition leads to more fragility before and during the recent financial crisis. 相似文献

We consider the role played by the European Union's Emissions Trading System (EU ETS) as a possible driver of outward foreign direct investment (FDI) for Italian manufacturing firms. Using a panel dataset of about 22,000 firms covering the first two phases of the EU ETS and the period before the EU ETS, we measure the patterns of FDI towards countries not covered by the EU ETS. The results show that the EU ETS had a weak effect on the number of new subsidiaries abroad (extensive margin), while it had a larger impact on production taking place in foreign subsidiaries (intensive margin), especially in trade-intensive sectors. 相似文献
