When time is (not) money: preliminary guidance on the interchangeability of time and money in laboratory-based risk research

The familiar adage that ‘time is money’ may not be entirely accurate according to research involving hypothetical choice: People’s decisions are less sensitive to temporal expenditures and outcomes than monetary ones. We provide a novel examination of whether similar patterns of risky choice are found for time and money when choices are consequential (i.e. monetary outcomes are obtained and temporal outcomes are experienced) – both for one-shot and repeated choices, over gains and losses. On the aggregate, across decision contexts (described and experienced), choices are similar for time and money. However, on the level of the individual, little relationship between risk preferences for time and money are observed. We discuss the theoretical and practical implications of these findings.     

Risk,jumps, and diversification

We test for price discontinuities, or jumps, in a panel of high-frequency intraday stock returns and an equiweighted index constructed from the same stocks. Using a new test for common jumps that explicitly utilizes the cross-covariance structure in the returns to identify non-diversifiable jumps, we find strong evidence for many modest-sized, yet highly significant, cojumps that simply pass through standard jump detection statistics when applied on a stock-by-stock basis. Our results are further corroborated by a striking within-day pattern in the significant cojumps, with a sharp peak at the time of regularly scheduled macroeconomic news announcements.     

U.S. Financial Services Consolidation: The Case of Corporate Credit Unions

This paper estimates a stochastic cost frontier forU.S. corporate credit unions using call report datafor 1992–1997. The results indicate that corporatecredit unions were 91 percent cost efficient, onaverage, over this period and that institutionspassing a larger percentage of their investments toU.S. Central Credit Union are more cost efficient. However, the economic magnitude of estimatedefficiency gains from investment concentration isfound to be modest. We conclude that the currentthree-tier hierarchical structure for the U.S. creditunion industry is likely to endure.     

Materiality in Corporate Governance: The Statement of Significant Audiences and Materiality

Materiality is an elusive, but fundamentally important concept in corporate reporting of all kinds—not only in traditional financial reporting, but in sustainability and integrated reporting as well. In the end, materiality is entity‐specific and based on judgment. Moreover, it is a judgment that should ultimately be made by a company's board of directors, which makes materiality as much a governance as a reporting issue. Whether a given ESG issue is material is in large part a function of the corporate stakeholders, or “audiences,” that the company's board of directors deems to be “significant”—that is, important to the company's ability to create value over the short, medium, and long term. The identification of such audiences—together with the time frames the board uses to evaluate the impact of the company's decisions on these audiences—provides the basis for determining the sustainability issues that corporate management must focus on for performance and reporting purposes. To help ensure that decisions about materiality receive the attention they deserve, the authors propose that corporate boards articulate their views in an annual “Statement of Significant Audiences and Materiality.” Contrary to the prevailing belief that the fiduciary duty of the board is to place shareholders’ interests first, nothing precludes corporate boards from issuing such a statement. Recent research, including the compilation of legal memos on fiduciary duty and nonfinancial reporting for all G20 countries, makes it clear that the board's fiduciary duty is to “the corporation itself.” In exercising this duty, directors have full discretion, under the business judgment rule and other authorities, to decide which audiences, along with the company's shareholders, should be deemed significant.     

Suffizienzorientierte Geschäftsmodelle am Beispiel von Stromspeichern

Business models are essential tools for understanding and creating the logic of a company’s business including all relevant stakeholders’ activities. Despite the knowledge of the organic-systematic interdependencies from companies with other stakeholders, business models of the energy economy primarily aim to transfer their value propositions via revenue streams into economical value. This article provides solutions for theoretical and practical extensions of business models for energy storaging to ensure they are sustainable in the future. Sufficiency-oriented energy storage business models are described as a sustainable framework.     

Assessing the impact of nocturia on health-related quality-of-life and utility: results of an observational survey in adults

Background and aim: The impact of nocturia (getting up at night to void) on health-related quality-of-life (HRQoL) is often under-estimated. This study investigated the relative burden in terms of HRQoL and utilities of nocturia in a real-world setting.

Methods: Patient data were collected from two surveys: a nocturia-specific, cross-sectional survey of physicians and their patients (DSP), and a general UK population health survey (HSFE). Utilities (EQ-5D-5L), productivity (Work Productivity and Activity Index), and the impact of nocturia symptoms (Nocturia Impact Diary and Overactive Bladder Questionnaires) were assessed against the number of voids. A robust linear regression model with propensity score weights was used to control for confounding factors in estimating utilities.

Results: Physician-recorded data were available from 8,738 patients across the US, Germany, Spain, France, and the UK; of these, 5,335 (61%) included patient-reported outcomes. In total, 6,302 controls were drawn from the two surveys and compared to 1,104 nocturia patients. Deterioration of HRQoL was associated with increasing number of night-time voids (p?p?p?Limitations: The cause of nocturia is multifactorial and the mostly elderly patients may have several concomitant diseases. The authors tried to adjust for the most common ones, but there may be diseases or unknown relationships not included.

Conclusions: Nocturia negatively affected HRQoL and patient utility. A clear effect is seen already at two voids per night. Every effort should, therefore, be made to reduce nocturia below the bother threshold of two voids per night.     

Beyond absorptive capacity in open innovation process: the relationships between openness,capacities and firm performance

The literature has shown that open innovation (OI) can be a winning strategy in improving firm performance. However, in order to adopt and implement it, managers need to resolve practical problems, such as understanding the role played by OI capacities and openness on firm performance. In response to these needs, this study aims to investigate the hierarchical relationships between openness, OI capacities and performance using a structural equation model approach. This paper also attempts to compare the levels of openness between firms in different industries to discover similarities and differences in OI phenomena. The analysis of data obtained from a survey of Korean firms shows significant interrelations between openness, OI capacities and firm performance. Our results go further in developing understanding of the building blocks on which successful OI is built and particularly suggest that desorptive capacity which underpins the out-bound OI process, is in turn strongly supported by knowledge management capacity. It is hoped that the results of this study can enrich our understanding of the OI mechanism and provide managerial and policy implications.     

Persuasion,pride and prejudice: how ads work

This paper compares the persuasion (strong) and reinforcement (weak) theories of advertising and uses neuroscience as the base for a third, MAC (Memory dominates Affect which in turn dominates Cognition), model of what advertising does for brands. All these models have practical significance for advertising strategy, creative briefing and client expectations. They set parameters for advertising research and measurement. The difficulty of measuring affect is not a good reason for ignoring it.     

Measures of marketing success

A mismatch of the meaning of “success”, as perceived by researcher and the firms researched, renders research less relevant and possibly, where the firm's resources are not directed at the goals selected by the researcher, misleading. This paper is concerned with the dependent variables used for business or marketing “success”, not its drivers, in seven leading marketing and strategy journals. The findings are that researcher, not respondent, views of performance dominate the literature which raises issues of relevance. Researchers are not necessarily being normative, and should be thoughtful in their selection of marketing performance objectives, i.e. the outcomes they seek to explain. A checklist of dependent variable considerations is provided together with a tentative definition of “success” against which performance may be compared.
