Determinants of endogenous price risk in corn and wheat futures markets

This analysis evaluates determinants of price variability in U.S. corn and wheat futures markets. The analysis is conducted in two segments. In the first segment, conditional heteroscedasticity models of price variability are estimated and used to examine the extent to which market conditions influence price variability. The second component of the analysis uses nonstructural vector autoregressive models to evaluate factors related to implied volatilities calculated from options premia. Our results indicate that corn and wheat price variability is significantly related to the ratio of use to stocks, futures market activity, and growing conditions. In addition, important seasonal and autoregressive effects are revealed. Our results provide an intuitive interpretation for GARCH and ARCH effects, which are often demonstrated for futures price data. © 2000 John Wiley & Sons, Inc. Jrl Fut Mark 20:753–774, 2000     

Customer retention and price matching: The AFPs case

Understanding the long-term price matching effects on CLV is important in evaluating the effectiveness of these policies in stimulating customer retention. In industries with low brand differentiation and low customer involvement (e.g., private pension system), it can be seen that choosing a brand is based on inertia. The objective of this article is to analyze the convenience for the firm of improving customer retention, by matching the lowest price in the Chilean private pension system. Results suggest that matching the industry's price leader reduces the firm's CLV, thus diminishing firm incentives to make this marketing effort.     

The theory of factor price differentials: The case of constant absolute differentials

Making use of the concept of a weakly bowed-out upper boundary of the transformation set, the paper shows that if differentials are absolute exogenous factor price differences, the generally agnostic conclusions of the literature, with regard to the ceteris paribus own supply responses and the effects of changes in differentials on employment levels of factors, are no longer justified. The implications of these results for the normative theory of factor price differentials and the relationship between the theory of factor immobility and factor price differentials are also analysed.     

Exploring factors driving social recruiting: The case of Australian organizations

This study identifies key factors driving the organizational adoption of social recruiting technologies, such as LinkedIn, Facebook, and Twitter. The Technology, Organization, and Environment (TOE) framework, as an initial exploratory approach, is used to identify underlying factors of new technology adoption. Qualitative evidence collected from 12 Australian firms serves to specifically categorize key determinants of the organizational adoption of social recruiting technologies. It is found that apart from several TOE factors that significantly influence the organizational decision making with reference to social recruiting, top management support is seen as imperative for successful adoption of recruiting technologies. Formalization, comprehensiveness, and strategic orientation of organizational human resource departments are closely linked to adoption of social recruiting at the firm level. In addition, job applicants’ readiness and local success stories have driven firms to adopt social recruiting technologies. The study extends and modifies the TOE model to provide the theoretical foundations of social recruiting in the context of Australian organizations and help human resource professionals and practitioners to gain a better understanding of key drivers of organizational social recruiting.     

The impact of agricultural and trade policies on price transmission: The case of Tajikistan and Uzbekistan

This paper examines the extent and speed of price transmission from international to local markets in two transition economies, Tajikistan and Uzbekistan. The two countries have similar economic backgrounds, but a notable difference is that Tajikistan has adopted a more liberal agricultural trade regime than Uzbekistan. We use a vector error correction model to analyse how global agricultural prices are transmitted to domestic food prices in the two countries. We find strong cointegration between world market and domestic prices in Tajikistan for food crops but not meat, and no cointegration in Uzbekistan.     

Consumer responsiveness to price differentials: A case for insurance industry deregulation

Proponents of deregulation have suggested that several industries should lose their antitrust exemptions and operate within a competitive atmosphere. An important assumption underlying deregulation arguments is that consumers will respond to price differentials in a manner that encourages price competition among supplier firms. This assumption is of special concern in the regulated fields of property and liability insurance. The intangibility of these products, the relatively long-term purchase commitments, and the intimate relationships between insurance and consumers' perceptions of risk raise substantial questions concerning individuals' reactions to price competition. In this study the amount of annual premium savings required to switch companies and the relationships between consumer characteristics and intended switching behavior were examined. The results suggest that a substantial segment of insurance buyers would change firms given modest price reductions. The size of this segment, along with the attitudinal and demographic characteristics of this group, indicates that price competition is a viable strategy in a deregulated insurance industry.     

On the recent extension of price and production statistics to health and education

The paper examines the recent extension of price and production statistics to health, social assistance services and education. In the first part of the paper it is emphasised that using net prices instead of gross prices, as for the European harmonised consumer price index, is inaccurate. The index is thus partly hybrid and inconsistent. The second part of the paper explains why, even if quality is a significant issue, production measures should not rely on the user's changes of condition. It should rather be based on supplied quality. The paper then describes and discusses two complementary ways to estimate quality changes.     

Analyst forecasts and price discovery in futures markets: The case of natural gas storage

We investigate analyst forecasts in a unique setting, the natural gas storage market, and study the contribution of analysts in facilitating price discovery in futures markets. Using a high‐frequency database of analyst storage forecasts, we show that the market appears to condition expectations regarding a weekly storage release on the analyst forecasts and beyond that of various statistical‐based models. Further, we find that the market looks through the reported consensus analyst forecast and places differential emphasis on the individual forecasts of analysts according to their prior accuracy. Also, the market appears to place greater emphasis on analysts' long‐term accuracy than on their recent accuracy. © 2009 Wiley Periodicals, Inc. Jrl Fut Mark 29:451–477, 2009     

Company visits and stock price crash risk: Evidence from China

Using a sample of Chinese listed firms, we observe that firms more visited by analysts or institutional investors exhibit lower future stock price crash risk. This effect is more pronounced for firms facing more incentives for or fewer constraints on hiding bad news. Greater mitigation of crash risk occurs if more firm-specific information is discovered during such visits and if visits are conducted by analysts instead of institutional investors. The impact of company visits is observed mostly in the first half of the subsequent year. These findings suggest that company visits mitigate crash risk by discovering and disseminating firm-specific information.

Insider trading laws and price informativeness in emerging stock markets: The South African case

We test the view that insider trading deters informativeness and, thereby, provide empirical evidence on the ramifications of insider trading legislation, particularly in an emerging market, that has hitherto received no research attention. Using the difference-in-differences identification strategy, we find that “effective insider trading law” improves stock price informativeness, a reflection of market efficiency, and that this efficiency is robust to both economic factors that affect market efficiency and the choice of control. Importantly, our results support the hypothesis that prohibition of insider trading elicits efficiency enhancement, particularly in emerging markets which are often characterized by weaker requisite institutional infrastructure than developed markets.     

Critical audit matters and stock price crash risk

Using manually collected data on the number and category of critical audit matters (CAMs) in the period 2016–2017, we investigate the hitherto unexplored questions of whether CAMs affect firm-specific crash risk, how CAMs influence crash risk in the Chinese capital market, and recognize CAMs that contain incremental information. Our findings are as follows: (1) Crash risk decreases after implementing the new audit standard requiring the disclosure of CAMs; (2) CAMs release negative information and change the capital market information environment; (3) only corporateidiosyncratic CAMs contain incremental information; (4) crash risk is mitigated only by CAMs disclosed by companies with a high shareholding of institutional investors. The main conclusion of our study is a positive assessment of the new audit standard and of CAMs in terms of protecting the interests of investors and strengthening the stability of the capital market to provide a new perspective for supervising the implementation of the new audit standard.     

Asymptotics for small nonlinear price impact: A PDE approach to the multidimensional case

We provide an asymptotic expansion of the value function of a multidimensional utility maximization problem from consumption with small nonlinear price impact. In our model, cross‐impacts between assets are allowed. In the limit for small price impact, we determine the asymptotic expansion of the value function around its frictionless version. The leading order correction is characterized by a nonlinear second‐order PDE related to an ergodic control problem and a linear parabolic PDE. We illustrate our result on a multivariate geometric Brownian motion price model.     

Ultimate government control and stock price crash risk: Evidence from China

Using data of Chinese firms over 2004–2018, we find that firms controlled by government entities, particularly central government entities, are less prone to stock price crashes, as compared with privately controlled firms. The effect is robust to alternative estimation approaches and moderated by the Split-share Structure Reform and the anti-corruption campaign. The results attest to the incentive alignment view that controlling and minority shareholders align their interests and stock prices perform well. Further, we find that government-controlled firms exhibit less financial opacity, undertake less risky investments, and appoint myopic CEOs, through which stock price crash risk is diminished.     

Weather derivatives valuation and market price of weather risk

This paper has two objectives: (1) to propose and implement a valuation framework for temperature derivatives (a specific class of weather derivatives); and (2) to study the significance of the market price of weather risk. The objectives are accomplished by generalizing the Lucas model of 1978 to include the weather as another fundamental source of uncertainty in the economy. Daily temperature is modeled by incorporating such key properties as seasonal cycles and uneven variations throughout the year. The temperature variable is related to the aggregate dividend or output through both contemporaneous and lagged correlations, as corroborated by the data. Numerical analysis shows that the market price of weather risk is significant for temperature derivatives. © 2004 Wiley Periodicals, Inc. Jrl Fut Mark 24:1065–1089, 2004
