To Launch or Not to Launch: An Empirical Estimate of New Food Product Success Rate

New product introduction is one of the most important activities for a company’s growth. It is generally accepted that new product introductions are essential to the health of food companies. Yet, many believe that most new products fail, therefore discouraging companies to introduce some new products. However, most of the estimates suggesting high failure rates are either anecdotal or qualitative. This article provides a quantitative approach to measuring new product success rates for food products and to show the relationship between the success of new product and entry strategies. This article uses a quantitative approach to measuring product success/failure exclusively for food products. The authors contend that failure rates for food products are not nearly as low, and success rates much higher than it was previously established in the literature and perceived by the industry professionals. There was a significant variability of success rates between various food groups ranging from 58% for both fruit and vegetables and desserts and ice-cream categories to 88% for baby food. Success rates also varied among the different introductory strategies of the new food products, ranging from 50% for new packaging to 75% for re-launch strategies.

Academics and practitioners usually quote very low success rates for new products based on subjective and/or strictly qualitative information. This empirical quantitative research shows that success rates for food products are much higher than previously reported. This should encourage greater use of new products to grow sales and profits. The previously reported low success rate may have led to the reluctance to introduce new products and therefore set many of the legacy food companies in their current poor financial condition.

The Relative Effect of Property Type and Country Factors in Reduction of Risk of Internationally Diversified Real Estate Portfolios

We examine and test the merits of diversifying portfolios of real estate securities internationally and across property types. Our analysis covers the period January 1990 through July 2005. Using data from the Global Property Research GPR 250 Property Securities Index, which has monthly prices for five property type indexes in 21 countries, we decompose country and property type sources of variation in real estate security returns. We find that property type effects are smaller than country effects. Property type specialization explains only 6% of the variance of national real estate securities index returns. Because property type effects are so small, country diversification is a more effective tool for achieving risk reduction than property type diversification. In addition, we find evidence that the relative importance of country effects is decreasing while that of industry effects is increasing. However, country effects continue to dominate property type effects.

转型期国有商业银行不良贷款控制策略探析

“二次剥离”加上国有商业银行自身的积极处置，国有商业银行不良贷款连续几年实现了“双降”。但无论从外部经营环境看，还是从银行内部分支机构间发展极不均衡的情况和股份制改革现状分析，不良贷款反弹的压力非常大。本文通过深入分析存量和新增不良贷款特征与成因，指出新增不良贷款一方面会严重制约国有商业银行改制转型乃至整个金融改革的顺利推进，另一方面积累到一定程度将会加剧国民经济的不稳定程度。鉴于此，作者提出从存量处置、增量控制、综合治理、市场拓展、流程再造、信贷整顿、精细化管理等方面加快创新，控制信贷风险．促使经营管理改革顺利推进。     

Hierarchical Models for the Analysis of Likert Scales in Regression and Item Response Analysis

Appropriate modelling of Likert‐type items should account for the scale level and the specific role of the neutral middle category, which is present in most Likert‐type items that are in common use. Powerful hierarchical models that account for both aspects are proposed. To avoid biased estimates, the models separate the neutral category when modelling the effects of explanatory variables on the outcome. The main model that is propagated uses binary response models as building blocks in a hierarchical way. It has the advantage that it can be easily extended to include response style effects and non‐linear smooth effects of explanatory variables. By simple transformation of the data, available software for binary response variables can be used to fit the model. The proposed hierarchical model can be used to investigate the effects of covariates on single Likert‐type items and also for the analysis of a combination of items. For both cases, estimation tools are provided. The usefulness of the approach is illustrated by applying the methodology to a large data set.     

Relationship between customer sentiment and online customer ratings for hotels - An empirical analysis

This study aims to establish a relationship between customer sentiments in online reviews and customer ratings for hotels. Customer sentiment refers to the emotions expressed by customers through the text reviews. These sentiments can be positive, negative or neutral. The study explores customer sentiments and expresses them in terms of customer sentiment polarity. Our results find consistency between customer ratings and actual customer feelings across hotels belonging to the two categories of premium and budget. Customer sentiment polarity explains significant variation in customer ratings across both the hotel categories. With regard to managerial implications, the study finds that, when compared with premium hotels, managers of budget hotels should improve their staff performance and hotel services. The present study is not exhaustive and other factors like customer review length and review title sentiment can be analyzed for their effects on customer ratings.
