This paper examines how firm characteristics and local anti‐corruption effort moderate the influence of political connections on enterprises’ private R&D investment using data from 2,587 Chinese A‐share listed enterprises. Our results show that the local anti‐corruption institutional environment significantly moderates the strong relationship between political connections and enterprises’ private R&D investment. Firm characteristics (i.e., firm size and firm age) also show a moderating effect on the relationship between political connection and enterprises’ private R&D investment; larger and older enterprises are more likely to have innovative resources and business cooperation partners, and thus are able to reduce their degree of reliance on political connections and government funding. The results of our study suggest the importance of having a transparent and fair institutional environment for enterprise innovation activities. 相似文献

We study the factors influencing the percentage of organic and fair trade certified coffee sold through a cooperative by growers of five cooperatives in Mexico. The percentage of coffee sold through the cooperative was used as a proxy of growers’ engagement with a cooperative. Using factor analysis and a fractional probit regression, we evaluated the proposition that the level of engagement can be explained by transaction cost economics, social norms and connections, and farmer and farm business characteristics. We found that farm size, uncertainty regarding cooperative time of payment to the members and cooperative commitment on price to be paid negatively influence the level of engagement. In contrast, asset specificity, relational commitment, and price have a positive impact on engagement. Our results may help cooperatives and policy makers to build strategies aiming to increase this level of engagement. This is relevant because lower grower engagement has been found to be positively correlated with weak performing cooperatives. 相似文献

The Portuguese textile and clothing industry thrived after 1960, when Portugal joined the European Free Trade Association, and it has been an important industry in Portugal in terms of value added, employment, and exports. Nevertheless, the industry has experienced significant challenges with the final integration of the apparel and textile industry into GATT on 1 January 2005, as well as the admission of relatively low-wage Bulgaria and Romania into the European Union in 2007. This paper describes recent trends in the industry between 1995 and 2016, including a substantial decrease in output after 2005 and recovery in recent years. In addition, a translog cost function is used to examine the existence of economies of scale, the relationships among inputs, and the effects of the 2005 GATT entry on the industry’s costs. The findings include strong evidence of economies of scale, consistent with the many small and mid-sized enterprises in the Portuguese textile and clothing industry. The results are also consistent with capital and labour being complementary inputs, while other input pairs are substitutes. The entry into GATT may have had a negative impact on cost, though the evidence for that effect is weak. 相似文献

We analyze the pay and position of 1009 faculty members who teach in doctoral‐granting economics departments at 53 large public universities in the United States. Using the Web of Science, we have identified the journal articles published by these scholars and the number of times each of these articles has been subsequently cited in published research articles. We find that research influence, as measured by various measures of total citations, is a remarkably strong predictor of the salary and the prestige of the department in which professors are employed. We also examine the effect of coauthorship. Surprisingly, we find no salary penalty for sharing authorship; however, in terms of prestige of employing department, coauthorship is fully discounted. 相似文献

ABSTRACT International retirement migration (IRM) is a growing phenomenon linked to increased longevity, early retirement, and improved financial status. Encompassing both travel and leisure experiences, IRM is a topic relevant to both tourism and leisure studies. By analysing the fictional movie series The Best Exotic Marigold Hotel (2012) and The Second Best Marigold Hotel (2015) from psychological, gerontological, and sociological theoretical perspectives, this paper examines motivation, goal setting, continuity and change, and identity development in IRM experiences within tourism and leisure contexts. This paper (a) identified motivations for IRM as finance, romantic relationships, social relations, self-esteem, self-fulfilment, and social norms; (b) in turn, time perception and attitude influence IRM emigrants’ priority and emotional fulfilment; (c) innovation extricates IRM emigrants from role loss and facilitates role change; and (d) IRM emigrants experience various identity development processes. A conceptual framework for IRM is proposed that purports to explain the IRM experience process and indicates that such an understanding of IRM should incorporate psychological, gerontological, and sociological perspectives. 相似文献

Orangutans are projected to become critically endangered or extinct this century if humans continue to destroy their habitat. Threats include legal and illegal clearcutting of rain forests to establish palm oil plantations, climate change, and transnational organized crime. This study examines how self-benefit and other benefit appeals, knowledge of threats, concern about habitat loss, and liking orangutans are associated with (a) intent to protect habitat due to licit threats and crimes against wildlife, and (b) seeking information to save habitat. Upon entry to a zoo, 251 (118 men, 128 women, and 5 unknown) persons viewed posters highlighting the benefits of habitat conservation to self or others and completed a survey. Concern, threat knowledge, liking, and self-benefit and other benefit appeals accounted for 28% of the variance associated with intent to take action to protect the habitat. Integrating social influence principles into zoo displays and addressing barriers that prevent conservation behavior are discussed. The ideas in this paper are relevant to many primates and endangered species. 相似文献

We construct a monetary economy with aggregate liquidity shocks and heterogeneous idiosyncratic preference shocks. In this environment, not all agents are satiated at the zero lower bound (ZLB) even when the Friedman rule is the best interest‐rate policy the central bank can implement. As a consequence, central bank stabilization policy, which takes the form of repo arrangements in response to aggregate demand shocks, temporarily relaxes the liquidity constraint of impatient agents at the ZLB. Due to a pecuniary externality, this policy may have beneficial general equilibrium effects for patient agents even if they are unconstrained in their money balances. 相似文献

Family involvement in business creates idiosyncrasies in firm behavior that promote long‐term, often transgenerational, strategic logics that ostensibly align with the motivations and outcomes of corporate entrepreneurship. Interestingly, extant research provides only minimal insight into the heterogeneous nature of corporate entrepreneurship orientations pursued by family firms. To better understand this heterogeneity, we develop a typology of corporate entrepreneurship in family firms providing a reconciliatory approach to this literary diversity and suggest that the varied corporate entrepreneurship orientations of family firms are impacted by the duality of a family's distinct intention to pursue transgenerational succession and capabilities to acquire external knowledge. 相似文献

On the day before the 2016 U.S. presidential election, the odds of Hillary Clinton winning the presidency, according to political prediction markets, were above 90%. Surprisingly, Donald Trump won the Electoral College handily. In this study, we examine how movements in specific stock prices foreshadowed the eventual outcome. Specifically, we conduct a series of standard event-study tests focused on pharmaceutical companies, which became a focal point during the presidential campaign. Results show that while stocks of pharmaceutical companies significantly underperformed the market prior to the election, prices substantially increased beginning three days before the election outcome. This increase is both statistically significant and economically meaningful and robust to various event-study methodologies. These results suggest that some sectors of the stock market seemed to anticipate the election outcome. 相似文献
