This study investigates financial analysts’ revenue forecasts and identifies determinants of the forecasts’ accuracy. We find that revenue forecast accuracy is determined by forecast and analyst characteristics similar to those of earnings forecast accuracy—namely, forecast horizon, days elapsed since the last forecast, analysts’ forecasting experience, forecast frequency, forecast portfolio, reputation, earnings forecast issuance, forecast boldness, and analysts’ prior performance in forecasting revenues and earnings. We develop a model that predicts the usefulness of revenue forecasts. Thereby, our study helps to ex ante identify more accurate revenue forecasts. Furthermore, we find that analysts concern themselves with their revenue forecasting performance. Analysts with poor revenue forecasting performance are more likely to stop forecasting revenues than analysts with better performance. Their decision is reasonable because revenue forecast accuracy affects analysts’ career prospects in terms of being promoted or terminated. Our study helps investors and academic researchers to understand determinants of revenue forecasts. This understanding is also beneficial for evaluating earnings forecasts because revenue forecasts reveal whether changes in earnings forecasts are due to anticipated changes in revenues or expenses.  相似文献

Considering the hazardous use of synthetic pesticides in vegetable production in urban West Africa, this research investigated the marketing potential of organic vegetables in the food vending sector of Cotonou (Benin), Accra (Ghana) and Ouagadougou (Burkina Faso). Certified organic production and marketing was examined as a potential strategy to improve chemical food safety. A stratified random sampling strategy was applied to study the preferences of food vendors (n = 180) and consumers (n = 360); vegetable use, risk perception, choice preferences and willingness-to-pay (WTP) for organic certification were specifically analyzed. The results showed that awareness of chemical contamination risks was generally low. Appearance of a product was central to vendor choice; consumers attributed similar utility to taste and organic certification. Consumer WTP was calculated to be a premium of 1.04 USD (per plate) if the food served contained only certified organic vegetables. In restaurants, this would mean an average premium of 19% for a meal. If certified organic vegetable production is to make a positive impact on food safety in urban West Africa, we suggest concentrating marketing efforts on the educated “elite” who frequent restaurants. However, considering that restaurant owners exhibited a lower preference for organic certification than lower class food vendors, the marketing situation is difficult. We therefore conclude that demand from the food vending sector alone will not institutionalize domestic certification mechanisms; this underlines the need for public commitment to facilitating such change.  相似文献

There are three positions concerning the economic effects of human rights discussed among economists. Some economists argue that only property rights matter for economic growth and basic human rights can even make the legal system less efficient. Others argue that negative rights are generally welfare increasing while positive rights tend to reduce income and growth over time. Yet a third group of economists argues that elements of all groups of human rights are a precondition for making productive use of one's resources and are thus efficiency‐enhancing. Based on a cross‐country analysis, the effects of different groups of human rights on economic growth are estimated in this paper. The transmission channels through which the different rights affect growth are identified by estimating their effects on investment and overall productivity. Basic human rights have indeed a positive effect on investment, but do not seem to contribute to productivity. Social rights, in turn, are not conducive to investment in physical capital but do contribute to productivity improvements. None of the four groups of rights covered in this analysis ever has a significant negative effect on any of the economic variables included.  相似文献

In this paper I explore the determinants of the corporate sell-off decision of diversified firms during the 1980s. The literature on sell-offs suggests performance, debt, number of operating segments, and level of ownership by officers and directors may play a role in the decision by firms to sell off assets. Empirical results show the probability of a sell-off is significantly negatively related to firm performance, significantly positively related to debt, significantly positively related to the number of business segments, and significantly negatively related to the level of officer and director ownership.  相似文献
