Market share determination in marketing service industries - A demand side approach∗

A marketing service industry provides its business clients with its services such as advertising media or inbound telecommunication ( i.e. toll free 800 calls) to increase their sales. By extending Dorfman and Steiner (1954) to the world where firms obtain costly marketing services from outside specialized providers, this paper studies the market shares of providers of a marketing service from the perspective of their clients. It derives that at the optimal point for a representative client, a provider's market share equals the ratio of the profits contributed by its service to the total profits contributed by the services of all providers in the market. Under certain conditions, a provider's market share is just a function of quality-price ratios. This result should facilitate choosing a marketing service from alternative providers and analyzing market shares in marketing-service industries.     

Equity returns,bond returns,and the equity premium in the German capital market

This article reviews the empirical evidence for equity returns, bond returns, and the equity premium in the German capital market for the period from 1870 to 1995. Taken together, the studies reviewed provide convincing evidence that over longer investment periods, average equity returns have been higher than average bond returns. These excess returns, however, have been highly volatile and negative in many years, illustrating the higher risk of equity investments. Moreover, market timing had a major positive or negative impact on overall returns. Despite the historical evidence of a substantial equity premium there is still little equity investment by German households.     

Examining Polish Market Mavens and Their Attitudes Toward Advertising

Abstract

In this paper, we offer some insights about Polish consumers with varying levels of general marketplace expertise, their role in diffusing product information, and their views of advertising. Market mavens are consumers who exhibit heightened interestin and knowledge about the marketplace. Because of their interest in communicating with others about the many aspects of the marketplace, these consumers can play an integral role for companies interested in diffusing marketing information. Our study results indicate that market mavens do indeed exist in Poland and they exhibit similar characteristics to market mavens identified in the U.S. They have more favorable attitudes toward advertising than other consumers. Additionally, they consider advertising as an important source of product and social image information. Although Polish mavens are less critical of advertising being misleading and confusing, they are concerned about advertising promoting materialistic values. Our findings imply that firms doing business in Poland would be well advised to target market mavens because they pay attention to advertising, have favorable attitudes toward advertising, and like to talk about marketplace phenomena with others.     

Efficient resource allocation under multi-unit demand

We study resource allocation with multi-unit demand, such as the allocation of courses to students. In contrast to the case of single-unit demand, no stable mechanism, not even the (student-proposing) deferred acceptance algorithm, achieves desirable properties: it is not strategy-proof and the resulting allocation is not even weakly efficient under submitted preferences. We characterize the priority structure of courses over students under which stability is consistent with strategy-proofness or efficiency. We show that stability is compatible with strategy-proofness or efficiency if and only if the priority structure is essentially homogeneous. This result suggests that efficient allocation under multi-unit demand is difficult and that the use of stable mechanisms may not deliver desirable outcomes.     

深化增值税改革的市场反应及影响因素

运用事件研究法和多元回归法考察 “深化增值税改革”（2018年3月28日国务院常务会议）的市场反应及其影响因素。结果表明：尽管中美“贸易战”对股市产生了较大的负面影响,但投资者仍将“深化增值税改革”视为利好消息,且试点行业的市场反应都显著为正。从市场反应影响因素来看,研发支出越多、融资约束越强的公司市场反应更好。此外,进一步细分公司特征发现,高税收敏感度和高产品市场竞争程度的公司市场反应更加积极,存在超额雇佣且研发支出较高以及不存在超额雇佣但融资约束较高的公司市场反应也更加积极。     

The valuation consequences of voluntary accounting changes

Firm management typically claims that voluntary accounting method changes (VACs) are made to enhance the informativeness of earnings by better matching accounting practices with economic reality. In contrast, skeptics argue that managers adopt new accounting procedures to opportunistically manage earnings and influence their firm’s stock price. In this paper, we investigate these alternative motives for VACs. Specifically, we investigate whether VACs cause equity prices to deviate from their fundamental values in the short-term by studying the long-run stock-price performance for a sample of firms that voluntarily change accounting methods. In addition, we investigate changes in earnings informativeness by examining the behavior of earning response coefficients and the relationship between earnings and future cash flows in years surrounding the VAC event. In contrast to prior research, we find little evidence that a strategy based solely on the earnings effect of a VAC can generate abnormal returns. While we find weak evidence of post-VAC abnormal returns for extreme VACs, this result appears to be driven by the accruals anomaly documented in Sloan [Sloan, R. G. (1996). The Accounting Review, 71, 289–315]. Our evidence further suggests that earnings informativeness is not significantly altered by voluntary changes in accounting methods. Taken together, our evidence suggests the market recognizes the financial statement effects of alternative acceptable accounting methods and efficiently processes the valuation implications of VACs.

Is the January effect still alive in the futures markets?

The January effect concerns the fact that small capitalization stocks have historically outperformed large capitalized stocks in January. We analyze evidence as to whether this anomaly can be exploited in the futures markets as a speculative investment or to add risk-adjusted value to portfolio performance. We find that the January effect is still alive in the futures markets on the Value Line minus S&P 500 spread trade, but that the marginal liquidity of the Value Line stock index futures contract has made it very risky to exploit the effect. Historically from 1982/3 to 2004/5, the trade has been profitable. This anomaly was also exploitable through a Russell 2000 minus S&P 500 spread trade from 1993/4 to 2004/5.

股票市场驱动并购研究述评

并购动机理论是并购研究的中心问题之一.从行为金融的角度出发,学者们提出了股票市场驱动并购(SMDA)的并购动机理论模型,这个模型回答了诸如"谁收购谁"、"现金收购还是换股收购"、 "并购浪潮怎么产生"等等问题.本文比较全面地总结了SMDA的理论模型和实证研究两个方面的成果,并做了简要的评述.
