The purpose of this study is to examine young American donors' perspectives toward disaster ad messages. Attitude toward helping others, social responsibility, ethnic identity on donation behavior, attitude toward ad, and advertising effectiveness were examined using 2 experimental variables (disaster location and message types). The findings explain that the constructs are positively related to each other and the 2 experimental variables significantly influence young Americans' attitudes toward ads and advertising effectiveness. In addition, young Americans expressed stronger feelings concerning attitude toward charity ads, and a higher level of advertising effectiveness was demonstrated when the disaster occurred domestically. Further, emotional messages were considered more persuasive than factual messages. As managerial suggestions, when charities work for domestic disasters, emphasizing patriotism and an emotional message can increase the positive attitude toward ads and advertising effectiveness. On the contrary, when charities work for international disasters, the messages should focus on diminishing distinctions between in‐group and out‐group perceptions.  相似文献

Retail and Wholesale Margins in Successive Cournot Oligopolies   总被引:1,自引:0,他引:1  
This paper studies the determination of retail and wholesale prices in successive Cournot oligopolies. It is shown that (i) the ratio of retail to wholesale margins increases (decreases, resp.) as the retail part of the market becomes less (more, resp.) competitive; (ii) the ratio of margin in one part of the market to total margin increases (decreases, resp.) as that part of the market becomes less (more, resp.) competitive; (iii) the decline in final consumer price is larger (smaller, resp.) if the entry of additional firm occurs in less (more, resp.) competitive part of the market. The results of the paper are applied to the case of third degree price discrimination.  相似文献

The Informational Role of Stock and Option Volume   总被引:8,自引:0,他引:8  
This article analyzes the intraday interdependence of orderflows and price movements for actively traded NYSE stocks andtheir Chicago Board Options Exchange (CBOE)-traded options.Stock net trade volume (buyer-initiated volume minus seller-initiatedvolume) has strong predictive ability for stock and option quoterevisions, but option net trade volume has no incremental predictiveability. This suggests that informed investors initiate tradesin the stock market but not in the option market. On the otherhand, both stock and option quote revisions have predictiveability for each other. Thus, while information in the stockmarket is contained in both quote revisions and trades, informationin the option market is contained only in quote revisions.  相似文献

This paper extends the static hedging portfolio (SHP) approach of  and  to price and hedge American knock-in put options under the Black–Scholes model and the constant elasticity of variance (CEV) model. We use standard European calls (puts) to construct the SHPs for American up-and-in (down-and-in) puts. We also use theta-matching condition to improve the performance of the SHP approach. Numerical results indicate that the hedging effectiveness of a bi-monthly SHP is far less risky than that of a delta-hedging portfolio with daily rebalance. The numerical accuracy of the proposed method is comparable to the trinomial tree methods of  and . Furthermore, the recalculation time (the term is explained in Section 1) of the option prices is much easier and quicker than the tree method when the stock price and/or time to maturity are changed.  相似文献

We investigate whether firms restructure board composition to align with changes in their contracting environment. Board size and independence increase with firm complexity, consistent with theoretical predictions. However, the hypothesized negative relation between board independence and information costs is evident only for firms completing acquisitions. Furthermore, board independence increases to offset increases in CEO power in a sample of firms making acquisitions, but decreases when CEO power increases in a large cross‐section of firms. We conclude that after the Sarbanes–Oxley Act of 2002, firms face constraints adjusting to target board structure, but these constraints can be mitigated by a shock to the contracting environment via acquisition.  相似文献

This paper examines the volume distribution of option trade prices that occurs when the underlying stock price remains constant. The width of these option trade price bands provides direct evidence on the law of one price and the redundancy of options assumed in many option models. We find that index option bands are narrower than equity option bands. Furthermore, for both equity and index options, puts have narrower bandwidths than calls. In general, option price bandwidth is narrow and can be explained by the minimum price movement allowed by the Chicago Board Options Exchanges (CBOE). This supports the single price law and the redundancy assumption. The existence of bid/ask quotes on the option does not materially affect the above results although it does alter the frequency of multiple option trade prices for a given underlying stock price. We note that over 53% of option trading volume occurs without bid/ask quotes on the CBOE compared to less than 15% a decade ago. Our results suggest that the effective bid/ask spread on options is probably no larger than the minimum price movements allowed by the CBOE. Furthermore, the need for the liquidity services of market makers may be declining if the decline in quoting activity stems from cross trading (i.e. trades not involving market makers).  相似文献

This paper examines the valuation effect of discretionary accruals for Japanese firms, taking into account the book value of equity. Consistent with US evidence, the Japanese market prices discretionary accruals, indicating that discretionary accruals enhance the value relevance of reported earnings. This value relevance is lower for cross-held firms, consistent with the view that cross-business shareholding aggravates tunneling or managerial opportunism through discretionary accounting choices. On the other hand, foreign shareholding and bond financing provide effective monitoring on managerial discretion of profit firms to enhance the valuation of discretionary accruals.  相似文献

This study solves a location‐then‐price game in which horizontal and vertical differentiation are combined using an asymmetric distribution of consumers’ taste. Boundary locations are robust when the taste disparity of the population is not large and out‐of‐market locations are not allowed. Firms may have incentives to move either inside or outside the market in other situations, so the equilibrium prices are never differentiated. The restrictions of vertical differentiation under this framework are further examined. A model with the entrance of a vertically differentiated product is also discussed.  相似文献

Two “laws” are used to describe the budget shares of staple food, other food, and non-food in 28 regions in China: Working's model, which describes the budget share of (total) food as a declining linear function of the logarithm of total consumption expenditure, and a second model that describes the ratio of the budget shares of staple and other food as a double-log function of total consumption expenditure. Staple food appears to be an inferior good in the richest regions but not in the other regions.  相似文献
