This study examines the effect of locally informed investors on market efficiency and stock prices using large power outages, which are exogenous events that constrain trading. Turnover in stocks headquartered in an outage area with 0.5% of U.S. electrical customers drops by 3–7% on the first full day of the outage, and bid–ask spreads narrow by 2.5%. Firm-specific price volatility is 2.3% lower on blackout dates. This effect is larger for smaller, lesser-known stocks and in higher income areas. Consistent with a valuation discount and higher expected returns for stocks with more informed traders, firms with a one-standard-deviation higher local trading propensity have market-to-book values that are 5% lower, Tobin's Q that is 6% lower, annualized four-factor alphas that are 1.2% higher, and average spreads that are 6.5% higher. Together, the evidence suggests that informed investors contribute disproportionately to both liquidity and price discovery, and that these contributions are reflected in valuations and expected returns.  相似文献

Recently, time‐driven activity‐based costing (ABC) has been developed as a cost modelling technique in which transaction times (that is, times required for particular occurrences of an activity) are calculated using time equations. This paper develops a model of the error structures in time‐driven ABC and examines the impact of adding terms to time equations on the accuracy of estimated transaction times. The results provide some fundamental insights into the balancing of errors when refining time equations and lead to some general recommendations that may be followed in the design process of a time‐driven ABC system to enhance the accuracy of times calculated by means of time equations.  相似文献

Drawing from the resource-based view and transaction costs economics, we develop a theoretical framework to explain why small and large firms face different levels of resource access needs and resource access capabilities, which mediate the relationship between firm size and hybrid governance. Employing a sample of 317 venture capital firms, drawn across six European countries, we empirically assess our framework in the context of venture capital syndication. We estimate a path model using structural equation modeling and find, consistent with our theoretical framework, mediating effects of different types of resource access needs and resource access capabilities between VC firm size and syndication frequency. These findings advance the small business literature by highlighting the trade-offs that size imposes on firms that seek to manage their access to external resources through hybrid governance strategies.  相似文献

We investigate the welfare cost of business cycles implied by matching frictions. First, using the reduced form of the matching model, we show that job finding rate fluctuations generate intrinsically a non-linear effect on unemployment: positive shocks reduce unemployment less than negative shocks increase it. For the observed process of the job finding rate in the US economy, this intrinsic asymmetry increases average unemployment, which leads to substantial business cycles costs. Moreover, the structural matching model embeds other non-linearities, which alter the average job finding rate and consequently the welfare cost of business cycles. Our theory suggests to subsidizing employment in order to dampen the impact of the job finding rate fluctuations on welfare.  相似文献

The paper investigates the extent of the impact from “hot money” or speculative capital inflow on the fluctuations of China's real estate market and stock market. The results indicate that hot money has driven up property prices as well as contributed to the accelerating volatilities in both markets due to its enormous size and its short-term characteristic of investing. In particular, we find that hot money ranks as the second largest contributor in the fluctuations of China's real estate prices. In the “risky” regime, which corresponds to more inflows and higher volatility of hot money, the effects are even more prominent.  相似文献

This paper explores the effect of European Union (EU) food safety regulations on EU imports of baby food. Pesticides and contaminants contribute to various health problems. Children are more vulnerable to the dangers of pesticides and contaminants because as soon as they start eating solids, they consume a limited number of food items, most of which are fruits and vegetables. To protect the health of the most vulnerable part of the population, the EU regulations stipulate that no more than 0.01 mg/kg of any single pesticide residue is permitted in baby food. In this respect, the EU differs from most of its trading partners, the majority of which do not differentiate food safety regulations according to the age of the consumer. The purpose of this paper is to compare the EU regulations on maximum residue limits of pesticides to those of its major competitors through a severity index. This index is then introduced into a gravity equation to assess the impact on EU imports of baby food. We find that the EU regulation had a negative impact on the volume of trade but a positive one on the probability of setting up new trade relationships.  相似文献

This study examines the clash between diversity policies as designed in the West and the challenges in implementing these in the Middle East and North Africa region. We contribute to the role of context in diversity management by studying how HR managers deal with diversity policies when the Western approach and the local context are perceived as being incompatible. Twenty HR/diversity managers working for multinational companies in nine different countries in the Middle East and North Africa region were interviewed. The findings show that a manager's understanding of the interrelated nature of multilevel factors of the local context influences the strategies adopted. Three strategies to deal with the perceived clash are identified: forcing a Western approach upon the local country, a reframing strategy where existing policies are reformulated to fit the Western requirements, and a sensitive approach in which the local context is considered. The study suggests that multinationa.l companies have to adapt diversity policies to local multilevel factors of the country in which they operate.  相似文献

Based on the reduced form New Keynesian Wage Phillips Curve, we estimate wage rigidity and indexation at the aggregate level in several advanced countries for the 1985–2014 period. We document that the wage setting process is heterogenous among our sample of countries: nominal wage rigidities are more important in the United States, while wage indexation is dominant in European Countries. We also present evidence that indexation to past inflation has decrease as inflation stabilizes at lower levels. In addition, our results suggest that wage rigidity is not linked to the institutional environment at the macroeconomic level. Finally, we show that there is significant time variation in the estimated coefficients on the implied equation that is usually not taken into account in the theoretical literature.  相似文献

This study investigates whether the timing of sponsorship disclosure affects viewers’ processing of sponsored content, and whether a disclosure influences the persuasive effect of the sponsored content. A model is proposed in which sponsorship disclosure enhances the recognition of sponsored television content as advertising, which leads to critical processing of the sponsored content. Ultimately, this negatively affects the attitude toward the brand in the sponsored content. This model was supported, but only when the disclosure was displayed prior to or concurrent with the sponsored content. These effects were not found for a sponsorship disclosure shown at the end of the program after the sponsored content. Theoretically, the findings emphasize the importance of disclosure timing. A disclosure displayed prior to or concurrent with the sponsored content, primes the sponsored content and provides sufficient processing time, so viewers recognize the content as advertising and can process it critically. In addition, the findings show that persuasion knowledge and critical processing are important underlying mechanisms for the effect of sponsorship disclosure on brand attitude. Regarding the practical implications for legislators and advertisers, this research demonstrates that sponsorship disclosure can make viewers aware of the sponsored content in television programs. Furthermore, this changes the processing of sponsored content and can also ultimately lead to resistance against persuasion.  相似文献
