Abstract

We study how price dispersion varies with product characteristics at a popular online price comparison site – Shopper.com. Our primary finding suggests that price dispersion in online markets varies with product characteristics and firm behavior. We also find evidence that the level of dispersion varies with the percent of firms listing price information in multiple categories. When the percent of firms listing prices in multiple categories is relatively high (low), price dispersion is low (high).

Abstract

Purpose

The purpose of this research is to prepare a dispersion resin with good dispersity and a colour paste with good stability. At present, the colour paste is being prepared using the pigment dispersion resin which has the group quaternary ammonium. The dispersion resin prepared has good dispersity of pigment and extender. However, the stability of storage and construction of the colour paste is relatively poor, which has a negative influence on the application of cathodic electrodeposited (CED) coatings. However, the detailed investigation on the dispersion resin and the stable colour paste has not been reported.

Design/methodology/approach

Three steps are adopted to prepare the dispersion resin, that is blocking toluene diisocyanate (TDI), quaternary ammoniation of blocked TDI and ring opening of epoxy resin. The resultant dispersion is used to prepare the colour paste. The factors, which have an influence on the dispersity of the dispersion resin and stability of the colour paste, are optimised.

Findings

The typical recipes of preparing the dispersion resin and the resultant colour paste are obtained. The dispersity of the dispersion resin and stability of the colour paste are good based on the typical recipe. In addition, the film of the CED coating is smooth, dense and hard when the colour paste is used in the CED coating.

Practical implications

The dispersion resin can be used to prepare a colour paste, which can be used in the CED coatings. In addition, it also can be applied as a binder of coatings and adhesions.

Originality/value

The factors, which have an influence on the dispersity of the dispersion resin and stability of the colour paste, are studied in detail. The typical recipes of preparing the dispersion resin and the resultant colour paste are obtained. Based on the typical recipe, the dispersity of the dispersion resin and stability of the colour paste are good.

Abstract

This paper provides a comprehensive analysis of online price dispersion in Europe, across a broad range of product categories and countries. Using the dominant European price comparison site we collected firm specific prices, weekly, from seven European countries (Denmark, France, Italy, Netherlands, Spain, Sweden and the United Kingdom) for 31 unique products, falling into five distinct product categories (printers, PDAs, scanners, games consoles, computer games and music), over the nine-month period October 2001 to June 2002. The resulting data set comprises over 17,000 individual price observations.

Using a number of alternative measures of price dispersion we find significant differences in the degree of price dispersion observed in online markets, both between countries and across product categories. We consider alternative explanations for online price dispersion and analyze their significance in explaining the observed differences.

Abstract

We investigate how online price dispersion has evolved since the bursting of the Internet bubble by comparing price dispersion levels in years 2000, 2001, and 2003 and between multi-channel and pure play e-tailers. The results show that although online price dispersion declined between 2000 and 2001 when there was a shakeout in Internet retailing, it increased from 2001 to 2003, the post bubble period, in particular, for desktop computers, laptop computers, PDAs, electronics and software. The proportion of items for which price dispersion at multi-channel retailers was higher than that at pure play e-tailers, increased steadily during 2000–2003. These findings suggest that online price dispersion is persistent even as Internet markets mature.

Abstract

Explained pay dispersion theory (Shaw, Gupta, & Delery, 2002) contends that the consequences of pay dispersion depend on two critical contingencies: (1) the presence of legitimate or normatively acceptable dispersion-creating practices, and the (2) identifiability of individual contributions. In this chapter, the first 20 years of empirical evidence and theoretical offshoots of this theory are reviewed. Other recent studies on the outcomes of horizontal and vertical pay dispersion are also evaluated. The review concludes with an evaluative summary of the literature and the identification of several potential fruitful areas for future research.

Abstract

Personnel economics tends be based on single-firm case studies. Here, we examine several internal labor market dimensions of nearly 5,000 firms, over a period of 20 years, using detailed matched employer–employee data from Portugal. In the spirit of Baker, Gibbs, and Holmstrom (1994a, 1994b), we consider worker turnover, the role of job levels and human capital as wage determinants, wage dispersion within job levels, the importance of tenure in promotions and exits, and the scope for careers. We find a large degree of diversity in most of these personnel dimensions across firms. Moreover, some dimensions are shown to be robust predictors of firm performance, even after controlling for time-invariant firm heterogeneity and other variables. These dimensions include low worker churning, the importance of careers, low wage dispersion at low and intermediate job levels, and a tight relationship between human capital variables and wages.

Abstract

In this paper, we review the literature on pay variation (e.g., pay dispersion, pay compression, pay range) in organizations. Pay variation research has increased markedly in the past two decades and much progress has been made in terms of understanding its consequences for individual, team, and organizational outcomes. Our review of this research exposes several levels-related assumptions that have limited theoretical and empirical progress. We isolate the issues that deserve attention, develop an illustrative multilevel model, and offer a number of testable propositions to guide future research on pay structures.

Abstract

This study examines several aspects of active portfolio management by equity hedge funds between 1996 and 2013. Consistent with the idea that cross-sectional return dispersion is a proxy for the market’s available alpha, our results show that equity hedge funds achieve their strongest performance during periods of elevated dispersion. The performance advantage is robust to numerous risk adjustments. Portfolio managers may use the current month’s dispersion to plan the extent to which the following month’s investment approach will be active or passive. We also estimate the active share for equity hedge funds and find an average of 53%. We further document the average annual expense ratio for managing hedge funds’ active share to be about 7%. This figure is remarkably close to active expense ratios reported previously for equity mutual funds, which may be interpreted as evidence of uniform pricing for active portfolio management services.

Abstract

Purpose

This paper aims to present a requirements analysis for the processing of water-based electrode dispersions in inkjet printing.

Design/methodology/approach

A detailed examination of the components and the associated properties of the electrode dispersions has been carried out. The requirements of the printing process and the resulting performance characteristics of the electrode dispersions were analyzed in a top–down approach. The product and process side were compared, and the target specifications of the dispersion components were derived.

Findings

Target ranges have been identified for the main component properties, balancing the partly conflicting goals between the product and the process requirements.

Practical implications

The findings are expected to assist with the formulation of electrode dispersions as printing inks.

Originality/value

Little knowledge is available regarding the particular requirements arising from the systematic qualification of aqueous electrode dispersions for inkjet printing. This paper addresses these requirements, covering both product and process specifications.

Abstract

The principle of tariffs dispersion, or differential tariffs depending on country of origin, is well known. For instance, Canada adapted a double column of tariffs after 1846, Spain in 1877, and Switzerland in the 1880–1890s. But there has never before been a comprehensive measure for any national economy, to our knowledge. This contribution proposes an original and exhaustive measure of customs tariffs dispersion depending on the origin of imported products for France between 1850 and 1913. Part of this dispersion arises indirectly as the result of compiling the nomenclature – or the schedule of categories – for France’s general trade chart. Our study nevertheless reveals the existence of direct discriminatory practices applied to certain countries for certain products. The creation of this measure yields important insights. First, tariff dispersion’s evolution completes the analysis of the chronology of trade policy. Second, it is possible to link tariff discrimination, imports in particular sectors, and national production. In our opinion, the paper should pave the way to work that reintroduces a country-specific dimension into the study of late 19th century commercial policy.
