Time and frequency domain causality Testing: The causal linkage between FDI and economic risk for the case of Turkey

This study aims to explore the causal relationship between economic risk and foreign direct investment (FDI) inflows for the case of Turkey. With the aim of establishing robust findings for the research in mind, both traditional and modern causality techniques are utilized; time domain Granger (1969, “Investigating Causal Relations by Econometric Models and Cross-Spectral Methods.” Econometrica 37: 424–438.), Toda and Yamamoto (1995, “Statistical Inference in Vector Autoregressions with Possibly Integrated Processes.” Journal of Econometrics 66 (1–2): 225–250.), Fourier Toda-Yamamoto and frequency domain Breitung and Candelon (2006, “Testing for short- and long-run causality: A frequency-domain approach.” Journal of Econometrics 132 (2): 363–378.) spectral causality test. Our empirical findings reveal that; economic risk changes in Turkey significantly lead to changes in FDI inflows. However, there is no evidence of causality running from FDI to economic risk. The findings imply that economic risk is an essential determinant of FDI inflows in Turkey. Our findings are compatible with historical macroeconomic developments in Turkey and imply important policy implications. The results of this study can be generalized for other emerging economies that have similar macroeconomic environments, in order to create useful policy implications regarding FDI inflow.     

The endo–exo problem in high frequency financial price fluctuations and rejecting criticality

The endo–exo problem lies at the heart of statistical identification in many fields of science, and is often plagued by spurious strong-and-long memory due to improper treatment of trends, shocks and shifts in the data. A class of models that has shown to be useful in discerning exogenous and endogenous activity is the Hawkes process. This class of point processes has enjoyed great recent popularity and rapid development within the quantitative finance literature, with particular focus on the study of market microstructure and high frequency price fluctuations. We show that there are important lessons from older fields like time series and econometrics that should also be applied in financial point process modelling. In particular, we emphasize the importance of appropriately treating trends and shocks for the identification of the strength and length of memory in the system. We exploit the powerful Expectation Maximization algorithm and objective statistical criteria (BIC) to select the flexibility of the deterministic background intensity. With these methods, we strongly reject the hypothesis that the considered financial markets are critical at univariate and bivariate microstructural levels.     

论我国大气污染生态补偿法律机制的完善

大气污染生态补偿法律机制对于促进区域大气污染联合治理、实现大气污染治理法律正义、创新与完善生态补偿法律机制等具有重要意义。我国现有法律法规就大气污染生态补偿进行了原则性规定,特别是山东、陕西、湖北等地方性法规更是对大气污染生态补偿进行了探索性规范,为大气污染生态补偿法律机制完善提供了有益经验。但从总体来看,我国大气污染生态补偿法律机制尚存在缺乏专门法律支撑、生态补偿主体过窄、补偿方式单一、补偿标准不合理、法律责任不完善等问题。为促进生态文明战略与强化大气污染生态补偿的法律保障,我国应以科学理念为指导,采取有效措施推进大气污染生态补偿法律机制完善。     

国有企业高管薪酬管制与委托代理问题

由于国企高管的经营业绩难以被准确度量，加上监督约束机制不健全，高管的超额薪酬成为国企代理问题的一种典型表现，于是政府将高管薪酬管制作为应急措施来降低代理成本，缓解国企代理问题。采用双重差分法对2011—2018年A股上市公司的分析表明：第二次限薪令在有效限制国企高管薪酬水平的同时，没有对高管在职消费产生显著影响，有效降低了国企代理成本；但第二次限薪令也降低了薪酬激励效应，导致国企高管努力程度降低，由此造成的利益损失又成为新的代理成本。国企薪酬制度改革面临激励与管制的两难选择，应在国企分类改革的基础上对不同类型国企的高管采取不同的激励机制：对公益类及特殊行业的国企增强高管政治晋升激励，对竞争行业（营利性）国企则应在推向市场的同时放松薪酬管制，从而有效降低代理成本，解决国企代理问题。     

Top management team incentive heterogeneity,strategic investment behavior,and performance: A contingency theory of incentive alignment

Research summary : We develop and test a contingency theory of the influence of top management team (TMT) performance‐contingent incentives on manager–shareholder interest alignment. Our results support our theory by showing that although TMTs engage in significantly higher levels of acquisition investment when their average incentive levels increase, investors' responses to those large investments are generally negative. More importantly, however, we further find that within‐TMT incentive heterogeneity conditions that effect, such that investors evaluate TMTs' large acquisition investments more positively as the variance in those top managers' incentive values increases. Thus, within‐TMT incentive heterogeneity appears to increase manager–shareholder interest alignment, in the context of large acquisition investments. Managerial summary : We find that as the average value of TMTs' incentives increase, relative to their total pay, they invest more in acquisitions and investors' respond negatively to the announcement of those deals. However, we further show that investors respond more positively to acquisitions announced by TMTs whose members' incentive values vary (some TMT members hold higher incentives and others hold lower). Results imply that when TMT members hold differing incentives levels, they approach investments from divergent perspectives, scrutinize those investments more heavily, and make better decisions, relative to TMTs with similar incentives. They also suggest that boards seeking tighter manager–shareholder interest alignment may benefit from introducing variance into TMT members' incentive structures, as doing so appears to create divergent preferences that can improve team decision making.

Forecasting in a Mixed Up World: Nowcasting Hawaii Tourism

We evaluate the short term forecasting performance of methods that systematically incorporate high frequency information via covariates. Our study provides a thorough introduction of these methods to the tourism literature. We highlight the distinguishing features and limitations of each tool and evaluate their forecasting performance in two tourism-specific applications. The first uses monthly indicators to predict quarterly tourist arrivals to Hawaii; the second predicts quarterly labor income in the accommodations and food services sector. Our results indicate that compared to the exclusive use of low frequency aggregates, including timely intra-period data in the forecasting process results in significant gains in predictive accuracy. Anticipating growing popularity of these techniques among empirical analysts, we present practical implementation guidelines to facilitate their adoption.     

CEO political ideologies and pay egalitarianism within top management teams

Research summary : We examine the influence of CEO and compensation committee liberalism on top management teams (TMT ) pay arrangements. Given that politically liberal individuals tend to value egalitarianism, we test whether firms with liberal CEO s tend to (1) reduce pay dispersion among non‐CEO executives; and (2) reduce pay gaps between CEO and non‐CEO executives, and whether compensation committee liberalism moderates these relationships. We find some evidence of a direct effect of CEO liberalism on TMT pay arrangements as well as some interaction between CEO and compensation committee liberalism on the pay arrangements. This study provides a better understanding of the antecedents of TMT pay arrangements and empirical evidence showing the influence of values at the top of organization . Managerial summary : Do the values of the CEO and compensation committee influence the pay of other top managers? Our study provides evidence that political ideology affects top manager pay. We examine whether CEO liberalism produces more egalitarian pay arrangements among top managers, and whether the liberalism of the compensation committee affects that relationship. We find that CEO liberalism reduces differences in the total pay among top managers, but does not influence the difference between CEO total pay and the total pay of top managers. We also find that compensation committee liberalism strengthens the negative influence of CEO liberalism on differences in total pay among top managers. Finally, we find that CEO liberalism reduces the difference between CEO bonus pay and the bonus pay of other top managers . Copyright © 2016 John Wiley & Sons, Ltd.     

Re-examining online customer experience to include purchase frequency and perceived risk

This research examines the important emerging area of online customer experience (OCE) using data collected from an online survey of frequent and infrequent online shoppers. The study examines a model of antecedents for cognitive and affective experiential states and their influence on outcomes, such as online shopping satisfaction and repurchase intentions. The model also examines the relationships between perceived risk, trust, satisfaction and repurchase intentions. Theoretically, the study provides a broader understanding of OCE, through insights into two shopper segments identified as being important in e-retailing. For managers, the study highlights areas of OCE and their implications for ongoing management of the online channel.     

一种改进的CPFSK信号频率估计方法

针对突发信号解调中多普勒频偏大的问题，提出了一种改进的连续相位移频键控信号(CPFSK)频率估计方法。首先接收信号平方运算使信号的调制指数加倍，再通过一次离散傅里叶变换(DFT)，用搜索信号平方谱谱峰的方法实现突发信号频率估计。仿真实验表明，在低信噪比条件下，该算法的频率估计精度比经典的相位差频率估计算法提高了20%；该算法与广泛用于高动态突发信号的频率插值估计算法相比，同道干扰信道下信干比改善可达4 dB，DFT长度缩短约1/3。
