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

Along the lines of Amihud and Mendelson (1987a, 1989,1991), this study investigates the unique trading mechanism of the Korea Stock Exchange (KSE) and its intraday behavior of stock price volatility. The evidence from this study indicates that the introduction of an additional clearing procedure at the afternoon closing makes price discovery process more efficient than before from the viewpoint of stock price volatility. Hence, such trading mechanisms can be applied to emerging stock markets as well as developed stock markets. In addition, based on intraday analysis, stock price volatilities appear to occur mainly during the trading period, not during the lunch break or overnight period. Consequently, the results confirm the previous studies that information arrival and trading activities are the main sources of volatility. 相似文献

Chordia, Roll and Subrahmanyam (2005, CRS) estimate the speed of convergence to market efficiency based on short-horizon return predictability of the 150 largest NYSE firms. We extend CRS to a broad panel of NYSE stocks and are the first to examine the relation between electronic communication networks (ECNs) and the corresponding informational efficiency of prices. Overall, we confirm CRS's result that price adjustments to new information occur on average within 5–15 min for large NYSE stocks. We further show that it takes about 20 min longer for smaller firms to incorporate information into prices. Most importantly, we demonstrate that the speed of convergence to market efficiency is significantly related to the type of trading platform where orders are executed, even after controlling for relative order flows, trading costs, volatility, informational effects, trading conditions, market quality, institutional trading activity, and other firm-specific characteristics. Our findings provide direct answers and insights to issues raised in a recent SEC concept release document. 相似文献

We analyze credit watch and rating actions to better understand the role of credit watches in the credit rating process. We find that watch actions are more frequently prompted by specific, publicly known events than are rating actions. The likelihood that a watch action precedes a rating action varies systematically with proxies for investor demand for credit quality information and the adverse consequences of issuing a rating change prematurely. Credit watches occur more often in response to deterioration in credit quality, and issuers make concerted efforts to address the concerns that prompted down watches. Down watches are less likely than up watches to indicate the direction of the subsequent rating change. Watch announcements are associated with abnormal stock returns, indicating that credit watch actions are significant information events. Our results suggest that credit watches are informative and facilitate the stability of ratings by allowing firms to correct deficiencies and prevent downgrades. 相似文献

A sports lottery in Korea presents a unique opportunity for comparing a parimutuel‐type sports lottery market against a bookmaker market outside the realm of horse racing. Using two‐ and three‐game soccer final‐score betting in the sports lottery market in Korea, which features matches in the English Premier League, we compare winning payoffs in this parimutuel‐type sports lottery against corresponding payoffs from an established bookmaker market in the United Kingdom. We find that for outcomes with relatively high payouts (that is, lower‐probability events), winning bets placed in the sports lottery market have greater payoffs than corresponding bets placed in the bookmaker‐based market. However, the opposite is true for outcomes with relatively low payouts (that is, higher‐probability events). Results suggest that participants in the sports lottery market tend to bet more toward high‐probability events than the amount implied by the bookmaker's odds. Results also suggest that the favorite‐longshot bias is still present in the bookmaker market, even when there is less threat of privately informed bettors than in horse racing. 相似文献

Little research examines the mechanisms for the relationship between expatriate utilization and subsidiary performance. Building on the knowledge-based view of the firm, we propose a multi-stage mediation model to explain how expatriate staffing promotes subsidiary financial performance. Our results underscore that expatriate utilization has an indirect, mediated effect on subsidiary financial performance through its links with subsidiaries’ knowledge creation and product performance. Adopting a moderated mediation approach, we also find that the indirect relationship between expatriate utilization and subsidiary product performance via subsidiary knowledge creation is strengthened by the context of transnational strategy as a moderating contingency. 相似文献

Retail and Wholesale Margins in Successive Cournot Oligopolies 总被引:1,自引:0,他引:1
Chongwoo Choe 《Australian economic papers》1999,38(1):1-8
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

We compare the Cournot and Bertrand equilibria in an asymmetric duopoly with product R&D competition. If a firm’s marginal cost is lower than that of its rival, then this firm (its rival) is referred to as the more (less) efficient firm. Under each mode of competition, there are three types of equilibria: blockaded-entry, deterred-entry, and accommodated-entry. Moreover, the presence of R&D investment makes it harder for the less efficient firm to survive. Cournot competition entails a unique equilibrium, whereas Bertrand competition may yield two equilibria. It is harder for the less efficient firm to survive under Bertrand competition than under Cournot competition. Versus Cournot competition, Bertrand competition yields higher industry output, and it shifts production from the less efficient firm to the more efficient firm. This result, together with the known size effect, explains the following three findings. First, the more efficient firm has a normal output ranking, whereas the less efficient firm may demonstrate an output reversal. Second, the more efficient firm may demonstrate a R&D reversal, whereas the less efficient firm has a normal R&D ranking (its Cournot R&D effort exceeds its Bertrand R&D effort). Third, Bertrand competition is more welfare-efficient than Cournot competition. 相似文献
