Relationship between city size and firm productivity – A new interpretation using the Chinese experience

This paper contributes to the literature on the relationship between city size and firm productivity by focusing on agglomeration, selection (market competition), and sorting (presence of firms with diverse productivity) effects using Chinese firm-level data for 1998–2013. Contrary to the existing literature, our parametric regression estimates from nearly two million firms show that when the selection effect is controlled, productivity advantage in big cities is reversed. This outcome is explained through a quantile regression showing the existence of left-sided sorting (inefficient firms sort themselves to larger cities) in big cities which is not captured in existing empirical literature. We further find that (1) left-sided sorting is stronger in exporters than non-exporters; (2) is also generated mainly in enterprises with high asset-liability ratios; and (3) selection has a positive effect on firm productivity, suggesting that market competition is key in an explanation of the rapid growth of big cities in China.     

Stock market reactions to domestic sentiment: Panel CS-ARDL evidence

This study sets out to explore the effects of business and consumer sentiment on stock market performance, within the separate contexts of advanced and emerging markets. The empirical analysis is carried out using the cross-sectionally augmented autoregressive distributed lag (CS-ARDL) modeling approach, which considers time dynamics, cross-sectional heterogeneity, and cross-sectional dependence. The findings for developed markets suggest that business sentiment has positive leading effects on stock returns, across short- and long-term time horizons, while for emerging markets, the price impact of business sentiment turns out to be short-lived. On the other hand, consumer sentiment tends to affect positively both market types, albeit only in the short run. Furthermore, the influence of sentiment indicators seems to be stronger in emerging- than in developed-market countries. The results remain robust, even after controlling for a rich range of potential predictors of stock returns. Generally, such evidence highlights the relevance of psychological factors, such as business and consumer sentiment, in determining the future trajectory of asset prices.     

研发市场界定的适用困境及应对策略

研发市场是经营者在特定产品和技术竞争中形成的市场范围。由于研发活动的不确定性，反垄断执法机关在界定研发市场时难以准确厘定市场边界，更深层次的原因在于维持竞争与激励研发的关系尚不明晰。研发竞争中的垄断行为难以通过相关市场界定的方式判断其违法性，需要结合具体案情和市场条件，动态分析涉案行为是否损害产品或技术研发竞争。     

Foreign direct investment and economic growth: Is more financial development better?

We investigate the extent to which an increase in financial development affects the positive effect of foreign direct investment on economic growth. Although the financial sector is beneficial for economic growth, the effect of further financial development on growth is found to become insignificant. Using a dynamic panel threshold model on 62 middle- and high-income countries spanning the period 1987–2016, we re-examine the possible nonlinearity between finance, foreign direct investment, and growth. Consistent with the “vanishing effect” of financial development, we find significant evidence that foreign direct investment fosters growth in general, but the growth effect of foreign direct investment becomes negligible when the ratio of private sector credit to gross domestic product exceeds 95.6%. This finding is robust to different econometric methods, various subsamples and interaction analyses, and distinct financial development indicators.     

The role of gender and its potential channels to affect self-employment in Taiwan

This research investigates the gender differences in the self-employment sector by employing a dynamic panel model with county- and city-level data from 1998 to 2016 in Taiwan. Our study is distinct from most others in this issue in that we explore not only the inter-gender difference, but also the intra-gender differences in self-employment. Following this framework, we first find that women are on average less likely to self-employ than men, and further find that older men, married men, men living in lower income regions and women living in higher income regions are more likely to become self-employed compared to their respective reference groups. We thus argue that gender influences self-employment not only directly but also through interactions with other demographic variables. Separate evaluation of different groups based on demographics should therefore result in better targeting of policies.     

Change or perish: Examining the role of human capital and dynamic marketing capabilities in the hospitality sector

Many researchers have endeavored to explain which factors contribute to sustainable competitive advantage. Toward this end, this study contributes to the marketing and hospitality management literature by providing empirical evidence on how human capital, dynamic marketing capabilities, and market dynamism influence competitive advantage in the hotel sector. We collected cross-sectional survey data from marketing and sales managers in 165 hotels, along with in-depth interviews in three hotels, based in four Gulf Cooperation Council (GCC) countries, namely, Saudi Arabia, Qatar, United Arab Emirates and Bahrain. The findings reveal that human capital directly, and indirectly through dynamic marketing capabilities, plays a critical role on developing competitive advantage. To contextualize this role, our research reveals that market dynamism moderates the mediated relationship between human capital and competitive advantage via market sensing capabilities. We discuss how the findings offer theoretical and managerial implications for the development of competitive advantage in the hotel sector.     

Is forest carbon sequestration at the expense of bioenergy and forest products cost-efficient in EU climate policy to 2050?

Forest management affects the quantity of CO₂ emissions in the atmosphere through carbon sequestration in standing biomass, carbon storage in forest products and production of bioenergy. The main question studied in this paper is whether forest carbon sequestration is worth increasing at the expense of bioenergy and forest products to achieve the EU emissions reduction target for 2050 in a cost-efficient manner. A dynamic cost minimisation model is used to find the optimal combination of carbon abatement strategies to meet annual emissions targets between 2010 and 2050. The results indicate that forest carbon sequestration is a low-cost abatement method. With sequestration, the net present costs of meeting EU carbon targets can be reduced by 23%.     

The development of integrated marketing communications at the British General Post Office, 1931–39

In the 1930s, the General Post Office (GPO) in Britain became one of the nation’s most innovative pioneers of marketing communication. Following criticism of the organisation in the 1920s for its conservative use of publicity, the GPO embarked upon a series of creative publicity campaigns that applied, amongst other methods, advertising, public relations, promotions, cinema, events and artistic posters. Through an overview of its publicity, and through a narrative of three case-studies, this article argues that one of the most important innovations of the GPO was its integration of marketing communication, both in terms of techniques used and in relation to its emphasis in promoting the organisation and the services it provided.     

Forecasting China's GDP growth using dynamic factors and mixed-frequency data

Forecasting GDP growth is important and necessary for Chinese government to set GDP growth target. To fully and efficiently utilize macroeconomic and financial information, this paper attempts to forecast China's GDP growth using dynamic predictors and mixed-frequency data. The dynamic factor model is first applied to select dynamic predictors among large amount of monthly macroeconomic and daily financial data and then the mixed data sampling regression is applied to forecast quarterly GDP growth based on the selected monthly and daily predictors. Empirical results show that forecasts using dynamic predictors and mixed-frequency data have better accuracy comparing to traditional forecasting methods. Moreover, forecasts with leads and forecast combination can further improve forecast performance.     

On the robustness of the competitive equilibrium: Utility-improvements and equilibrium points

We show that the set of competitive equilibrium points of a pure exchange economy are the equilibrium points of a broader class of better-response demands than the usual utility-maximizing demand functions. The better-response demands are derived from assigning weights to all commodity bundles with higher utility than the current commodity bundle, with the greatest weights being placed on the commodity bundles with the highest utility gain. The usual utility-maximizing demand functions are then those in which the weight on the utility-maximizing bundle is one. We also show that these better-response demands belong to a large class of response maps that are generated by monotonic transformations of the utility functions and/or monotonic transformations of the weights assigned to the commodity bundles.
