National cultural effects on leverage decisions: Evidence from emerging-market ADRs

We examine leverage decisions in the context of national culture over the 1996–2010 period. Cultural characteristics can explain capital structure decisions from emerging-markets cross-listings. The results show that firms from countries with high Individualism and Indulgence employ more debt. Firms located in countries with high Power Distance, Masculinity, Uncertainty Avoidance, and Long-term Orientation are less leveraged. Additionally, Exchange-traded and capital-raising ADRs are more likely to be from countries with weaker corporate governance. Univariate tests show that capital-raising ADRs employ less debt relative to non-capital-raising ADRs, and notably, in the post-cross-listing period. Interestingly, the home country's cultural characteristics of capital-raising and exchange-traded ADRs exert less influence on their capital structure decisions. Our findings suggest that there is a value discount associated with increased firm leverage. Our insights have practical implications for portfolio managers attempting to enter emerging markets through the use of ADRs. Moreover, investors can evaluate the often neglected effect of cultural values into firm performance.     

Technologies in caregiving: professionals’ strategies for engaging with new technology

This article explores the adoption of new technology in organisations that provide senior citizen care. Inspired by Niklas Luhmann’s systems theory, we study how technology reduces complexity by identifying client needs and ensuring predictability in service delivery. However, how technologies are adopted in practice is not determined by technology since it is also structured by care-workers' continuous decision-making. Against this backdrop, we explore how technologies alter the conditions for decision-making in two settings of elderly care, and we describe how care workers seek to adapt technologies to their practical needs as well as conception of care ethics. Developing a systems theory approach, the article eschews a priori assumptions of technological constraint on care-workers’ professional autonomy, offering a more open-ended exploration of diversified strategies for coping with new technology. Our case studies show that employees develop diversified strategies for technology adoption, including both non-usage, heated resistance, excessive embrace, and creative adaption.     

双液位计量分离器计算原油产量与含水率及理论

克拉玛依油田稠油和稀油的生产过程中,对油井产出液的含水率测定,经历过化验、含水分析仪两个阶段。含水分析仪在测定稠油含水率时,黏液粘在含水分析仪的探头上时而测得含水率100％,时而含水为零,含水分析仪在稠油的生产过程中有很大的局限性。利用油水密度差的特性,通过两个液位计的位差计算出井流物的含水率。在油井的生产中期以前准确度高,操作方便,成本低。     

AN EVOLUTIONARY PERSPECTIVE ON DIVERSIFICATION AND CORPORATE RESTRUCTURING: ENTRY,EXIT, AND ECONOMIC PERFORMANCE DURING 1981–89

This study proposes a theoretical perspective that firms engage in continuous search and selection activities in order to improve their knowledge base and thereby improve their performance. This general framework is applied to the context of corporate evolution. Entry and exit activities are understood as search and selection undertaken by the firm to improve their performance. One of the compelling features of this framework is that firms learn from their past entry experience and approach the next entry in a more focused and directed manner over time. Also, firms acquire additional knowledge from each entry event while applying their existing knowledge base. With a longitudinal (1981–89) data base on entry and exit activities of all publicly traded manufacturing firms in the United States, this study shows that applicability of the firm's knowledge base plays an important role in predicting which businesses a firm enters or exits. Firms sequentially enter businesses of similar human resource profiles and firms are more likely to divest lines of business of different profiles. Corporate-level analysis shows that such well-directed entry and exit contribute to the improvement of a firm's profitability.     

NAFTA as a Means of Raising Rivals' Costs

The North American Free Trade Agreement (NAFTA) was designed to reduce tariff rates between Mexico, Canada and the U.S.A. over a period of ten years. However, lower tariff rates are only available to firms that comply with complicated and costly NAFTA filing regulations. Such regulations raise costs of small firms relative to large firms in a domestic industry which engages in trade between NAFTA countries. This implication of NAFTA regulations can lead to increased concentration in domestic industries, an hypothesis which can be tested as the transition period comes to an end. Finally, our model suggests an explanation for why the levels of trade from the U.S.A. to Mexico have been lower than general expectations.     

Myopic loss aversion and the equity premium puzzle reconsidered

Benartzi and Thaler [The Quarterly Journal of Economics 110 (1995) 73–92] offer a quasi-rational explanation for the equity premium puzzle. We reconsider their methodology and, making a simple modification to it, find that their analysis is not robust.     

On Microfoundations of the Dual Theory of Choice

We show that Yaari's dual theory of choice under risk may be derived as an indirect utility when a risk-neutral agent faces financial imperfections. We consider an agent that maximizes expected discounted cash flows under a bid-ask spread in the credit market. It turns out that the agent evaluates lotteries as if she were maximizing Yaari's dual utility function. We also generalize the dual theory of choice for unbounded lotteries.     

Steering the Sales Force for New Product Selling: Why Is it Different,and How Can Firms Motivate Different Sales Reps?

This study investigates how to direct and assemble the sales force for new product selling. In a first step, the authors draw on self‐determination theory to explore and empirically test a threefold conceptualization of motivation. Results provide insights into why sales force steering works differently in the new product selling context. Specifically, results show that for new products’ financial performance, internalized new product selling motivation is more important than intrinsic and controlled motivation. In a second step, the authors show how firms can motivate different sales reps to achieve higher financial performance of new products. In doing so, they examine the interaction effects of sales reps’ predispositions and widespread firm‐steering instruments on new products’ financial performance. Results reveal that the new product sales orientation of the bonus strengthens the positive relationship between sales reps’ performance predisposition and new product financial performance but weakens the relationship between sales reps’ learning predisposition and financial new product performance. Moreover, results reveal that the new product sales orientation of the periodic review strengthens the positive relationship between sales reps’ learning predisposition and financial new product performance. A post hoc analysis shows that a differentiated steering approach that matches appropriate steering instruments with sales reps’ varying predispositions substantially enhances reps’ financial new product performance.
