The number of patent applications filed at the Chinese State Intellectual Property Office SIPO grew tremendously over the last decades and the SIPO has become the world's third largest patent office by 2009. In this paper, we provide an overview of the institutional background of patent examination in China. Moreover, we empirically analyze the determinants of the grant lags applicants have to expect at the SIPO. The multivariate duration analysis is based on the population of 443,533 patent applications filed at the SIPO between 1990 and 2002. The average grant lag is 4.71 years with considerable variation across 30 different technology areas. Interestingly, we find that Chinese applicants are able to achieve faster patent grants than their non-Chinese counterparts (even after controlling for various other determinants of grant lags). This might be an indication of a differential treatment of Chinese applicants which would be in violation of Art. 3 (National Treatment) and Art. 4 (Most-favored Nation Treatment) of TRIPS that has been signed by China in 2001.

We examine a multinational firm which has a decreasing marginal cost, and the optimal sales tax policies of the regions where that firm operates. We show that the regions set higher sales taxes than those given by a cooperative equilibrium. Each region fails to fully internalize the effects of its tax level on another region's welfare and the incentives for that region's authority. Exponential cost functions which exhibit economies of scale (for example Cobb-Douglas) and linear demand functions satisfy our assumptions. Our results suggest the need to coordinate sales tax levels between countries and between smaller entities, like states in the United States. Smaller regions benefit more from such coordination. Lowering sales taxes in each region increases welfare for all regions, profits for firms, and consumer welfare.

We study the properties of a profit-maximizing monopolist's optimal price distribution when selling to a loss-averse consumer, where (following K?szegi and Rabin (2006)) we assume that the consumer's reference point is her recent rational expectations about the purchase. If it is close to costless for the consumer to observe the realized price of the product, then - in a pattern consistent with several recently documented facts regarding supermarket pricing - the monopolist chooses low and variable "sale" prices with some probability and a high and sticky "regular" price with the complementary probability. Realizing that she will buy at the sale prices and hence that she will purchase with positive probability, the consumer chooses to avoid the painful uncertainty in whether she will get the product by buying also at the regular price. If it is more costly for the consumer to observe the realized price, then - in a pattern consistent with the pricing behavior of some other retailers (e.g. movie theaters) - the monopolist chooses a sticky price and holds no sales. In this case, a sale is less tempting and hence less effective in generating an expectation to purchase with positive probability. We also show that ex-ante competition for loyal consumers leads to sticky pricing while ex-post competition leads to marginal-cost pricing, and discuss several other extensions of the model.

We study a two-player dynamic investment model with information externalities and provide necessary and sufficient conditions for a unique switching equilibrium. Within this setup, we ask whether policymakers should interfere when better informed agents make individual investment decisions. We find that when the public information is sufficiently high and a social planer therefore expects an investment boom, investments should be taxed. Conversely, any positive investment tax is suboptimally high if the public information is sufficiently unfavorable. We also show that an investment tax may increase overall investment activity.

This article introduces "career entrepreneurship," a rapidly spreading phenomenon in the global knowledge-driven economy. Career entrepreneurship involves taking an entrepreneurial approach to managing our careers. It means doing things that seem "illegitimate" to other people and contradict socially-recognized and accepted sequences of work experiences in terms of age, education, or socio-economic progression. This kind of behavior challenges established norms about typical career development. The evidence presented in this article suggests new possibilities for thinking about the way individuals invest in their careers, new insights for organizations interested in capturing the potential of career entrepreneurship, and new ideas for career and life coaches to support people embracing the phenomenon. The article offers a primer on career entrepreneurship to all three groups of readers, calling for more effective collaborative relationships and more effective leveraging of individuals' career investments.

This research builds on the complementary corporate social responsibility (CSR) literatures in strategy and marketing to provide insight into the efficacy of CSR as a challenger's competitive weapon against a market leader. Through an investigation of a real world CSR initiative, we show that the challenger can reap superior business returns among consumers who had participated in its CSR initiative, relative to those who were merely aware of the initiative. Specifically, participant consumers demonstrate the desired attitudinal and behavioral changes in favor of the challenger, regardless of their affective trust in the leader, whereas aware consumers' reactions become less favorable as their affective trust in the leader increases. Furthermore, participation, unlike mere awareness, transforms the nature of the consumer-challenger relationship from a transactional one to a communal, trust-based one.

Payment card networks, such as Visa, require merchants' banks to pay substantial "interchange" fees to cardholders' banks, on a per transaction basis. This paper shows that a network's profit-maximizing fee induces an inefficient price structure, over-subsidizing card usage and over-taxing merchants. In contrast to the literature we show that this distortion is systematic and arises from the fact that consumers make two distinct decisions (membership and usage) whereas merchants make only one (membership). These findings are robust to competition for cardholders and/or for merchants, network competition, and strategic card acceptance to attract consumers.
