The demand structure for yogurt is assumed to be properly described by a one level nested logit model that is applied to aggregate
market data. Given the presence of endogenous regressors, suitably lagged endogenous variables (Arellano and Bover in J Econom
68:29–51, 1995; Blundell and Bond in J Econom 87:115–143, 1998) are proposed as instrumental variables. The validity of this
set of instruments is discussed and price elasticities and marginal costs are recovered from the demand estimates. Total welfare
gains associated to the introduction of two new brands by the same manufacturer are finally computed. Prices and profits decreased
and total welfare increased. 相似文献

Two cases of liposarcoma of the stomach are described. At computed tomography (CT) the neoplasms showed features of an aggressive malignant tumor, with no fatty values within. We discuss the differential diagnosis of such lesions and conclude that, although rare, liposarcoma should be considered as a possible diagnosis when a large exophytic gastric mass is detected at CT. 相似文献

This paper examines residents' perceptions of a wide set of externalities exerted by the development of cruise tourism. The research involved data collection in two ports located in the two largest Mediterranean islands, Sicily and Sardinia, during the summer peak of the cruise season 2011. These two cruise destinations are especially interesting as they are characterized by a distinct life cycle. The empirical findings show that the two groups of residents have statistically equal perceptions on cruise activity in their destination. A correspondence analysis shows that residents have an overall positive attitude on the development of cruise tourism with respect to social, cultural and economic impacts. Nevertheless, they also feel that cruise activity has a negative impact, especially on the environment. Heterogeneity in occupation is explicitly taken into account. These findings provide directions for local policy‐makers. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

A growing number of Local Public Transport (LPT) companies diversify their production lines by providing a large set of services. We investigate the cost structure of a sample of LPT companies operating in Italy and assess the presence and the magnitude of scope economies. We split the whole sample of firms according to their diversification strategy: private firms, mainly diversifying in competitive transport related services and public firms providing nontransport services in regulated markets. Scope economies appear sizeable for both groups but higher for firms pursuing a transport related strategy, suggesting caution in the multiutility development pursued by public LPT firms in Italy. 相似文献

We exploit a dataset that includes the individual tax returns of all taxpayers in the top percentile of the income distribution in Germany to pin down the effective income taxation of households with very high incomes. Taking tax base erosion into account, we find that the top percentile of the income distribution pays an effective average tax rate of 30.5% and contributes more than a quarter of total income tax revenue. Within the top percentile, the effective average tax rate is first increasing, then decreasing, with income. Since the 1990s, effective average tax rates for the German super‐rich have fallen by about a third, with major reductions occurring in the wake of the personal income tax reform of 2001–05. As a result, the concentration of net incomes at the very top of the distribution has strongly increased in Germany. 相似文献

Abstract A ‘two-stage growth’ discounted cash flow (DCF) model is built to test whether changes in the underlying market fundamentals help to explain movements in stock prices. Empirical results on two samples of US and EU stocks show that the ‘fundamental’ earning price ratio (E/P) explains a significant share of cross-sectional variation of the observed E/P, this impact being stronger in the US market. It is also found that: (i) the fundamental component of the E/P has superior explanatory power than simpler measures of expected earnings growth; (ii) ‘non-fundamental’ components, interpreted as signals reducing asymmetric information (such as firm size, the number of forecasts and the chartist momentum), mitigate the role of the fundamentals; (iii) current deviations from the fundamentals are affected by ex post adjustment of publicly available information in the EU sample. It is argued that differences in regulatory environments and in the composition of investors between the US and EU financial systems may help to explain these comparative findings. Results appear consistent with the ‘market integrity hypothesis’ postulating that reliance on publicly observable fundamentals is higher when insider trading is lower. 相似文献

The primary goal of our study is to explore cross-national differences in attitudes and perceptions about product placements, after investigating measurement invariance. Our cross-national focus includes three countries that have not been compared previously: Finland, Italy and the USA, which differ significantly in terms of the evolution/maturity of product placement markets, regulatory structures and cultural contexts. Motivated by earlier studies, we investigate the cross-national measurement invariance of scales to measure four research constructs related to the product placement domain (attitude toward credibility of advertising, attitude toward advertising-in-general, attitude toward placement-in-general and attitude toward regulation of placements). Our research also extends earlier work focused on similar constructs from a cross-national perspective. Results from multi-group analyses using a structural equation modeling approach indicate important and statistically significant differences in latent means between the three countries for all four constructs of research interest. Substantive explanations of these differences and their implications for future practice and research are discussed. 相似文献
