Research productivity patterns in the organizational behavior and human resource management literature

Closely following the analysis approach used for similar studies in the economics and finance literature, we present the first study to examine if there exists an empirical regularity in the bibliometric patterns of research productivity in the organizational behavior (OB) and human resource management (HRM) literature. Our results present strong evidence that there indeed exists a distinct empirical regularity. It is the so-called Generalized Lotka's Law of scientific productivity pattern: The number of authors publishing n papers is about 1/n^c of those publishing one paper. The observed pattern in the OB and HRM area is interestingly very consistent with those in much older, related business disciplines.     

Explaining Variance in Policy Evaluation Regularity. The Case of the Flemish Public Sector

Abstract

The objective of the article is to identify the conditions that best explain organizational variance in policy evaluation regularity. Relying on the innovative Most Similar Different Outcome/Most Different Similar Outcome technique, we examine the explanatory ability of a range of organizational attributes applied to eighteen Flemish public sector organizations (Belgium). The conditions that relate to the source of evaluation demand, in its broadest sense, are of key importance. We refer to the role of the sector minister and other organizations in demanding evaluations, as well as to the media and parliamentary attention and the influence of EU evaluation clauses.     

Heterogeneous beliefs with herding behaviors and asset pricing in two goods world

We construct a incomplete information equilibrium model with heterogeneous beliefs and herding behaviors to identify their joint effects on the dynamics of asset prices. Herding behaviors make investors revise some of their estimations about expected growth rates of goods streams toward to the other one’s by a manner of weighted average of their own forecast and the other’s. As we expected, herding behaviors generate influences on the Radon Nikodym derivative, that is so-called “sentiment” as in Dumas et al. (2009), and in turn not only impact the dynamics of asset prices but also generate influences on investors’ survivals. We also show that introducing heterogeneous beliefs with herding behaviors permits to explain both the Backus–Smith puzzle and the mixed results about the influences of herding behaviors on asset prices. Moreover, we uncover that herding behaviors have positive influences on stocks’ risk premiums.     

Sustainable development carbon pricing initiative and voluntary environmental disclosures quality

Although corporate environmental disclosures have been researched extensively, empirical evidence regarding the indirect impact of carbon pricing on firms' voluntary disclosures is scarce. The objective of this study is to identify the indirect impact of carbon pricing initiatives on the voluntary environmental disclosures (VEDs) of electricity generating companies, analyzed through the lens of institutional theory. This study adds to the growing literature on the determinants of VED, investigating the impact of adoption of the Global Reporting Initiative and ISO 14001 on VED. Secondary data were collected from 2015 annual reports and/or standalone sustainability reports of electricity generating companies from 53 countries around the world. Content analysis approach was adopted for measuring the extent of the quality of VED. Findings of multiple regression analysis suggest that there is an indirect institutional impact of carbon pricing on the quality of VED. This study also finds that, as the form of nongovernment guidance, the Global Reporting Initiative adoption and ISO 14001 certification also have an institutional influence on the VED. VED is also affected by company size although this study reveals no significant relationship of leverage with VED.     

Q‐FACTORS IN EMPIRICAL ASSET PRICING: A REVIEW AND SYNTHESIS

The latest development in the asset pricing literature is the emergence of empirical asset pricing models comprising q‐factors (profitability and investment factors) in conjunction with other factors. However, as in the case of the older empirical models, there is scepticism regarding the application of these newer factor models consisting of q‐factors because of the debate surrounding the explanatory power of these empirically inspired asset pricing models. This review attempts to synthesize studies pertaining to the four alternative explanations of the asset pricing models comprising the q‐factors (profitability and investment) – the data snooping hypothesis, the risk‐based explanation, the irrational investor behaviour explanation and the interpretation that suggest that the combination of the risk‐free asset and the factors comprising the model span the mean‐variance efficient tangency portfolio that prices the universe of assets.     

Price competition in the spatial real estate market: allies or rivals?

This paper examines whether real estate firms can avoid price competition when properties in the vicinity are priced by allies. An oligopoly model with differentiated products generally suggests that real estate firms engage in price competition with their spatially closest rivals. Yet, they can raise property prices when the market share of their allies increases. To test this prediction, a spatial autoregressive model with spatial autoregressive disturbances, including a share of allies in the vicinity, is estimated using data on the prices of residential condos in central Tokyo, Japan. The model prediction is supported by the empirical results. In the data set, the magnitude of the market share on property prices increases with the expansion of the size of the spatial market.     

Indifference pricing with uncertainty averse preferences

We consider the indifference valuation of an uncertain monetary payoff from the perspective of an uncertainty averse decision maker. We study how the indifference valuation depends on the decision maker’s attitudes toward uncertainty. We obtain a characterization of comparative uncertainty aversion and various characterizations of increasing, decreasing, and constant uncertainty aversion.     

Proposal for calculating regulatory capital requirements for reverse mortgages

In the current context in which many people worry about the sustainability of pension systems, reverse mortgages are gaining popularity because they are a way to supplement elderly people's incomes. However, it is necessary to provide banks with an adequate risk measurement and management procedure for reverse mortgages to increase the commercialization of these products, which will result in greater well-being for the retirement age population. In this paper, we propose a method to measure risk and estimate the regulatory capital requirements for a portfolio of reverse mortgages owned by a financial institution according to Basel II and III. The method considers house price risk, mortality risk and interest rate risk; consequently, regulatory capital requirements need to be computed using a Monte Carlo simulation procedure. The proposed method is general and can accommodate several scenarios for reverse mortgage specifications, including fixed or variable mortgage rates and different income stream schemes (with the lump sum as a particular case). The results for the U.K. show that reverse mortgage providers face higher risk when the lender initially advances a higher amount, with the lump-sum case indicating the highest risk, for relatively younger borrowers, the female population, higher interest rates and floating mortgage rates.     

Production quality and pricing strategy for substitutable products under comparison effects

Comparison effects have been studied extensively in many fields. In particular, existing operations management articles have discussed the impact of comparison effects on enterprises' production and pricing decisions. Research has also shown that consumers' purchasing decisions are primarily determined by three factors: product quality, selling price, and comparison effects. The current study introduces the concepts of social and temporal comparison effects to examine how comparison effects influence a monopolist’s production quality and pricing strategy for substitutable products. Results reveal the following: (1) Setting different prices for even two types of substitutable products with negligible quality differences can divide customers into three groups under the influence of social comparison effects in a single-stage model. (2) The monopolist should avoid using a price discrimination strategy in which products with a short market life cycle have the same quality but different prices. (3) When the market life cycle of products is sufficiently long in the single-product market and the market with two substitutable products, the monopolist’s optimal choice in the second stage is to keep production quality constant and increase the selling price. Consequently, the number of buyers does not decrease because of temporal comparison effects. Therefore, the firm increases its revenue. (4) For the market with two substitutable products with quality differences, one approximate optimal strategy for the enterprise in the second stage is to keep the selling price constant with the assumption that product quality cannot be adjusted after the first period. At this point, the consumption situation in the market is the same as that in the first stage. Therefore, when no external constraints exist, the monopolist firm can obtain more benefits in the second stage than in the first stage by exploiting the temporal comparison effects of consumers in the second stage. (5) When consumer identity information can be confirmed in the market, social comparison effects, similar to temporal comparison effects, could help the enterprise increase its price and profit while maintaining product quality. These social and temporal comparison effects constrain consumers. Thus, the number of people who continue to buy products does not decrease.     

存贷款利差定价分析

存贷款利差合理水平取决于违约率、损失率、流动性风险、资本缓冲与信贷类资产的比率,以及无风险基准利率。银行业内部管理水平不足和存贷款市场的总体失衡会导致利差水平扩大和提高。我国当前的存贷款利差水平相对于其合理水平而言过低,不仅不利于银行业长期健康发展,而且也对整个金融体系累积了巨大的体系性风险。
