Patterns of growth in Chinese cities: Implications of the land lease

A special feature of China’s housing market is land use rights in the form of land leasehold contracts granted by the government. We consider an equilibrium model in which a representative developer may choose to redevelop existing centrally located housing or to develop new housing at the periphery of the city. We show that as the city grows, the land leasehold system results in the city center being developed less intensely and more land being used on the outskirts of the city when compared to a fee simple environment. Thus, cities in China are likely to be relatively more spread out, with city centers relatively older than would be the case with “fee simple” ownership. Our model suggests that excess residential land use is about 6 percent. In addition, compared with the ownership case, housing supply will grow more quickly in the near future, but more slowly later on during the transition of the Chinese economy. Parallel to the supply growth pattern, equilibrium price grows relative slowly in the near future, but more quickly later on. While we focus on residential uses, we believe our model can be applied to other land uses.     

Beta and firm age

We document a robust pattern of beta declining over the age of a firm. We find that changes in systematic risk via firm characteristics and life-cycle stages are insufficient to explain this pattern. Moreover, standard proxies for the quantity and quality of information also explain this pattern only partially. To fully explain this pattern we rely on the increasingly important role of familiarity in financial decision making: familiarity is a determinant of beta and firm age is a proxy for the degree of familiarity that investors feel toward individual stocks. To illustrate the implication of our findings, we document that when we control for firm age there is support for the CAPM and its use as an input for the cost of equity capital calculation.     

I am who I am: Sharing photos on social media by older consumers and its influence on subjective well-being

We are faced with an aging population whose longer lives need to be lived well. Extant marketing scholarship has largely neglected older consumers' behavior in relation to the social media realm and its influence on well-being. This two-stage qualitative study investigates subjective well-being, exploring whether and how sharing photos on social media increases the dimensions of self-acceptance, positive relations with others, autonomy, environmental mastery, purpose in life, and personal growth. The findings indicate that photo-sharing is a powerful behavior in augmenting older consumers' well-being as it enables individual self-reflection, self-representation and transforms the individual experience into a collective one. Contributions include, that photo-sharing acts as a bridge in creating, reinforcing but also breaking bonds among older consumers, also a tension exists between the desire for autonomy and the need for relationships with others, and finally that the digital self is a component of subjective well-being in older consumers.     

REGIONAL ANTI‐CORRUPTION EFFORT,POLITICAL CONNECTIONS AND FIRM INNOVATION EFFORT: EVIDENCE FROM CHINA

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.     

Relative age effects in political selection

We exploit a regression discontinuity design to provide causal evidence of the relative age effect (RAE) on a long-run adult age outcome: Political selection. We find strong evidence of the RAE in politics in Finland. However, the effect is heterogeneous: We find that male candidates born early in the calendar year have a significantly higher probability of getting elected to the parliament but no similar RAE applies to female candidates nor to municipal elections. Moreover, this effect only takes place in the most competitive parliamentary districts and is present only for some parties. We also find that in all the groups where the RAE does not exist, early-born candidates are under-represented suggesting attrition of talent in the candidate placement. Overall, our results show that seemingly artificial cutoffs imposed by the government have persistent consequences even on the selection to the highest positions of power within a society.     

Exploring consumer attitudes to online collaborative consumption: A typology of collaborative consumer profiles

Online collaborative consumption enhances peer networks, members of which communicate, collaborate, and even deliver services to one another via digital sharing platforms. Despite the tremendous increase in collaborative consumption, due in large part to the development of the Internet, the reality of the economic and social movements that underpin this trend is much less visible. Of course, not all consumers seek collaborative consumption or interact through online platforms. Using a qualitative approach, this paper aims to investigate motivational factors and barriers against collaborative consumption and to establish a typology of collaborative consumer profiles, identifying the most suitable type of online sharing platforms for each profile. The findings reveal the following collaborative consumer profiles: committed, pragmatists, intermittent, and skeptical, each demonstrating different preferences for the different type of online sharing platform.     

Beyond antitrust populism: Towards robust antitrust

The populist use of competition policies is on the rise again, associated with the growth of big-tech companies in the era of digital platforms. This article sees antitrust populism as a re-emerging force in the United States and Europe via greater politicisation of competition law enforcement. It addresses the basic tenets of antitrust populism in order to expose the fundamental problems that populist use of competition law entails. I argue for a rethink of antitrust policy on the intellectual foundations laid down by what Mark Pennington describes as ‘robust political economy’. We need greater regulatory humility and antitrust enforcement which takes both innovation and welfare seriously.
