资本市场促进技术创新的效率研究——以西部地区为例

在运用Malmquist指数的基础上,笔者测量了我国西部地区12个省市资本市场促进技术创新的全要素生产率(TPF)、技术效率变化指数(TECH)以及技术进步率指数(TPCH),比较和分析了西部地区各省市资本市场促进技术创新的效率水平。运用12个省市的专利和资本市场融资面板数据建立回归方程进行验证,发现各省市资本市场在促进当地创新效率方面还不均衡;资本市场发展较好以及技术创新潜力较大、需求较高的地区,资本市场融资投入对技术创新的全要素生产率也较高。     

Enhancing adaptive transfer of cross-cultural training: Lessons learned from the broader training literature

Drawing insights from the broader training literature, we argue that evaluation of cross-cultural training effectiveness should adopt comprehensive criteria, including cognitive, skill-based, and affective learning outcomes as well as adaptive transfer. We propose that the integration of an error management supplement in cross-cultural training can enhance trainee acquisition of self-regulation skills and self-efficacy that facilitate adaptive application of learning to novel cultural situations. In addition to the traditional error management training designs (i.e., positive error framing), the current paper describes additional design elements to promote acquisition of cognitive strategies, prevent premature automaticity, alleviate concerns about error occurrence during learning, and enhance readiness to transfer. In addition, we offer propositions regarding the effects of the supplement on learning and transfer outcomes, along with implications for future research and practice on cross-cultural training.     

The economics of markets and platforms

Advances in the study of both markets and platforms contribute to economics. Platforms are typically digital markets, although platforms can designate markets generally. So, the economics of markets and the economics of platforms are one and the same. Platforms show the critical role of intermediaries in endogenous price adjustment and market clearing. The platform model remedies problems with general equilibrium analysis by combining and extending the basic Walrasian and Marshalian market models. The analysis of platforms provides explanations for the bid–ask spread, including market power, search costs, matching costs, adverse selection, and moral hazard. The study of platforms demonstrates the importance of participation and coordination in the formation of markets. The discussion emphasizes that platforms have significant implications for the theory of the firm. The analysis further considers how platforms affect innovation and entrepreneurship.     

‘Market failure’ arguments are a poor guide to policy

‘Market failure’ is frequently offered as a justification for government intervention in the economy. Proponents of interventions can point to almost limitless examples of markets which do not meet all the criteria for Pareto optimality and argue that government taxation, subsidies or regulation can perfect them, maximising social welfare. But comparing market outcomes with an unattainable and unidentifiable ideal is not useful in a world of imperfect knowledge and government failure. It is better to compare market outcomes against realistic alternatives. Furthermore, even within the market failure paradigm, concepts such as ‘public goods’ and ‘negative externalities’ are routinely misunderstood and inconsistently applied. This leads to predictably poor policy outcomes.     

THE EFFECTS OF ECONOMIC REGULATION IN THE ISTANBUL TAXICAB MARKET

This paper discusses the regulation of the Istanbul taxicab market and its consequences. While price and entry regulations are common to many taxi markets, there are significant differences in their institutional frameworks. We examine the problems of the Istanbul market and offer recommendations to improve its efficiency.     

WHY FREE MARKETS SHOULD NOT BE BLAMED FOR THE CURRENT RECESSION

Interventionist thinkers are now claiming intellectual victory, blaming the free‐market system and its ideology for the current economic collapse. We find this thesis untenable, drawing on the Austrian Business Cycle Theory. Instead, we argue that the roots of our present downturn lie in the monetary system, whose institutional structure is far from any free‐market ideal. Moreover, several government policies have contributed to the problems.

资产减值、非经常性损益与盈余管理研究——以＊ST大地（002200）为例

采用案例研究法,以绿大地的存货减值准备计提为出发点,试图找出绿大地利用资产减值准备进行盈余管理的证据,进而挖掘出其盈余管理的手段与动机。研究结果表明：绿大地通过资产减值准备＂经常性损益＂项目与＂非经常性损益＂之间＂分类转移＂的方式实施盈余管理,主要动机在于为第二年扭亏为盈做准备,避免被ST,以满足资本市场的监管要求。     

On the importance of the long-term seasonal component in day-ahead electricity price forecasting with NARX neural networks

Daily and weekly seasonalities are always taken into account in day-ahead electricity price forecasting, but the long-term seasonal component has long been believed to add unnecessary complexity, and hence, most studies have ignored it. The recent introduction of the Seasonal Component AutoRegressive (SCAR) modeling framework has changed this viewpoint. However, this framework is based on linear models estimated using ordinary least squares. This paper shows that considering non-linear autoregressive (NARX) neural network-type models with the same inputs as the corresponding SCAR-type models can lead to yet better performances. While individual Seasonal Component Artificial Neural Network (SCANN) models are generally worse than the corresponding SCAR-type structures, we provide empirical evidence that committee machines of SCANN networks can outperform the latter significantly.     

Commonality in liquidity among Middle East and North Africa emerging stock markets: Does it really matter?

This study investigates commonality in daily liquidity among 11 emerging stock markets from the Middle East and North Africa from January 2005 to June 2017. First, we test long memory in liquidity in these markets. Second, we select a number of factors eligible to affect liquidity commonality among local, regional and global factors. We find that regional and US factors do not explain liquidity variations in all the markets that exhibit low sensitivity to external factors. Our results are robust to the use of alternative proxies. The analysis in sub-periods confirms our results showing that most markets are not very sensitive to fluctuations and external shocks of liquidity. For international investors, stock markets in the Middle East and North Africa present an opportunity for further diversification, as these markets exhibit weak correlations between them and with the global market with regard to liquidity.
