Abstract This study examines the mediating role of volatility on the relationship between analyst recommendations and herding in the Malaysian stock market by using data from 2010 to 2020. Volatility is measured by realized volatility and the Parkinson estimator. The empirical evidence suggests that herding exists and realized volatility intervenes in the direct relationship between analyst recommendations and herding. The release of analyst recommendations causes realized volatility to fluctuate and investors are triggered by the volatility, which in turn follow the crowd to herd. Nonetheless, the Parkinson estimator is found to be insignificant, which infers that investors have anchor bias and rely on previous day stock prices to trade and herd. This paper provides an alternative explanation to the direct relationship and enhances the study of information-based herding. It contributes to academicians, practitioners, investors and policymakers to understand the herding of investors in responding to the arrival of new information.

Abstract The article presents the current state of evolutionary economics against the backdrop of changes related to the potential use of the achievements of other social sciences, in particular psychology, as well as dynamically developing neuroscience. The article suggests a synthesis of evolutionary and behavioural economics concepts as a logical consequence of evolutionary cooperation processes in social sciences. Interdisciplinary initiatives create new perspectives on generation synergy effects for all participants. Contemporary evolutionary economists present the nature of ongoing innovation-driven economic change as a long evolutionary process. The main creator of the econosphere as a global system is a man–entrepreneur who is also the result of evolutionary processes. For this reason evolutionary economics should take into account the results of behavioural economics’ research based on modern psychology and neuro-science. The cornerstone of evolutionary and behavioural economics synthesis are the theories of Adam Smith which should be regarded as his holistic intellectual heritage.

Abstract This study aims to explain the association between the quarterly data obtained over the period 2007: Q2–2020: Q3 for Turkey and the countercyclical capital buffer (CCyB) proposed within the framework of Basel III with banking performance and risk indicators. For this purpose the association among the variables was analyzed using the ARDL model and by performing the Toda Yamamoto (T-Y) causality test. According to the analysis results, it was determined that the CCyB has a statistically significant and positive relationship with the capital adequacy indicators of the banks in the long-run, however, it has a statistically significant and negative relationship with the asset quality risk and currency risk indicators. In the short-run it was determined that the CCyB has a statistically significant and positive relationship with the capital adequacy, profitability and liquidity indicators and similar to the long-term relationship, it has a statistically significant and negative relationship with the asset quality risk and exchange rate risk indicators. According to the causality test results, a statistically significant and unilateral causality running from the indicators of capital adequacy, asset quality and exchange rate risk to the CCyB was detected. The obtained estimation results indicate that the CCyB can be increased by policymakers during the periods when the performance indicators of the banking sector rise, whereas can be decreased by policymakers during the periods when the risk indicators of the sector rise. Furthermore, the results of the study asserted that the CCyB was an appropriate instrument for mitigating the macroeconomic and systemic risks for Turkey.

Abstract This study investigates the interaction between fiscal and monetary policies and how crises affect the coordination between policymakers in Turkey. This study’s novelty is that a nonlinear Taylor rule indicating monetary policy response function is estimated based on the Threshold Generalized Method of Moments (Threshold GMM) methodology over the period January 2006—March 2020. The empirical findings reveal that when fiscal policy has an expansionary stage, especially in crises times, the policy interest rate does not react significantly to the inflation gap, output gap and real effective exchange rate gap in expansionary periods. On the contrary the policy interest rate gives statistically important responses to these variables during contractionary fiscal policy periods. Thus, the effectiveness of the Taylor rule appears in a period of contractionary fiscal policy. This situation gives rise to the significant policy implication that the monetary policymaker’s success in controlling inflation increases with the contractionary fiscal policy. Finally, it has been observed that effective coordination between monetary and fiscal policies did not occur during crisis periods, but compatible coordination was achieved in other periods.

Abstract This paper provides a look into what Lucas meant by the term ‘analogue systems’ and how he conceived making them useful. It is argued that any model with remarkable predictive success can be regarded as an analogue system, the term is thus neutral in terms of usefulness. To be useful Lucas supposed models to meet further requirements. These prerequisites are introduced in two steps in the paper. First, some properties of ‘useless’ Keynesian macroeconometric models come to the fore as contrasting cases. Second, it is argued that Lucas suggested two assumptions as the keys to usefulness for he conceived them as referring to genuine components of social reality and hence as true propositions. One is money as a causal instrument and the other is the choice-theoretic framework to describe the causal mechanisms underlying large-scale fluctuations. Extensive quotes from Lucas’s unpublished materials underpin the claims.

Abstract This study presents a dynamic general equilibrium model with an explicit employment period and investigates economic fluctuations to a temporary productivity shock. Numerical experiments indicate oscillatory responses of new hiring and employment to the shock which are not observed in a standard flexible price model. The explicit employment period constructs an overlapping structure of employment which results in the oscillatory response. This study also examines the effects of change in employment period to economic fluctuations and shows that the variations in new hiring are higher when the employment period is long.

Abstract The literature on financial sustainability is scattered in such a way that a synthesis is indispensable. The present study on an annotated bibliography of financial sustainability seeks to fill this particular gap by presenting a collation of published literature in the sphere. The sectorial analysis depicted that ability to cover the costs from its own resources and ability to pay debt were the key dimensions to measure financial sustainability. The majority of the studies were found in the public sector covering local governments and central governments particularly in such European countries as Spain, Italy and England. Earning enough resources, asset sustainability and the ability to repay obligations are the three dimensions to assess financial sustainability. The study also pointed out the key research areas, variables and analytical tools among other trends in the literature. The present study assists the future researchers in reviewing the literature on financial sustainability and developing research methodology.

Abstract The aim of the paper is to examine the impact of environmental, social and corporate governance (ESG) responsibility on the short- and long-term cost of debt. Linear regression was applied to a unique dataset on CSR and cost of debt for 300 companies recognized in 2017 by Corporate Knights as the most sustainable companies in the world. The question about the link between CSR and cost of debt is important as there is still ongoing debate as to whether business should undertake activities in the field of CSR—managers and other stakeholders are still unsure of the outcomes. The findings show that the involvement in environmental issues decreases the cost of long-term debt whereas the involvement in social issues brings benefits to short- and long-term debt. Surprisingly the greater the involvement in corporate governance, the higher the cost of debt in all time horizons. Managers should expect a lower cost of debt from environmental and social activities mostly in the long run. Corporate governance expenditures may in turn be seen as a waste of company resources, cost of forgone opportunities, or—optionally—as an over-investment. The main novelty is the breakdown of CSR into three dimensions while examining various term structures of corporate debt.

Abstract In economic studies researchers are often interested in the estimation of the distribution function or certain functions of the distribution function such as quantiles. This work focuses on the estimation quantiles as inverses of the estimates of the distribution function in the presence of auxiliary information that is correlated with the study variable. In the paper a plug-in estimator of the distribution function is proposed which is used to obtain quantiles in the population and in the small areas. Performance of the proposed method is compared with other estimators of the distribution function and quantiles using the simulation study. The obtained results show that the proposed method usually has smaller relative biases and relative RMSE comparing to other methods of obtaining quantiles based on inverting the distribution function.

Abstract One-criterion decision making under uncertainty (1-DM/U) is related to situations in which the decision maker (DM) evaluates the alternatives on the basis of one objective, but e.g. due to numerous uncertain future factors some parameters of the problem are not deterministic. Instead of entirely known paramaters, a set of possible scenarios is available. Multi-criteria decision making under certainty (M-DM/C) concerns cases where the DM assesses particular options in terms of many objectives. The parameters are known. Therefore, scenario planning is redundant. Both issues are investigated by many researchers and practitioners, since real economic decision problems are usually at least uncertain or multi-objective. In the paper, numerous analogies between 1-DM/U and M-DM/C are revealed. Some of them have existed for many decades, but others, so far, have not been developed. A careful examination of all the similarities enables an improvement of existing methods and a formulation of new algorithms for 1-DM/U and M-DM/C. The article presents six pairs of similar procedures and contains the description of three novel approaches created by analogy to existing ones.
不确定条件下的单准则决策(one -criterion decision making under uncertainty, 1-DM/U)是指决策者在一个目标的基础上对备选方案进行评估，但由于未来的诸多不确定因素，问题的某些参数是不确定的。不是完全已知的参数，而是一组可能的场景。确定性下的多标准决策(M-DM/C)涉及决策管理根据许多目标评估特定选项的情况。参数是已知的。因此，场景规划是多余的。这两个问题都被许多研究人员和实践者调查，因为实际的经济决策问题通常至少是不确定的或多目标的。本文揭示了1-DM/U和M-DM/C之间的许多类比。其中一些已经存在了几十年，但其他的，到目前为止，还没有开发。仔细检查所有相似之处，可以改进现有方法，并制定1-DM/U和M-DM/C的新算法。本文介绍了六对类似的程序，并描述了通过类比现有方法创建的三种新方法。
