Spanning with futures contracts

Regression-based testing techniques have long been used to quantify whether the efficient frontier of a set of assets spans the frontier of a larger collection of investments. This paper derives regression-based spanning tests for the case in which the investment possibilities set contains, or is constituted by, futures contracts for which marked-to-market margins are explicitly taken into account. Two empirical applications illustrate our results.     

Governance for sustainable tourism: a comparison of international and Dutch visions

This study focuses on the role of public authorities in the governance of tourism for sustainable development at national level. Departing from an overview of international recommendations, it analyses whether those recommendations are reflected in the way public authorities influence domestic tourism in the Netherlands. The conclusion is drawn that, currently, the internationally recommended horizontal and vertical coordination of public authorities and their policies is missing. This is largely due to a design approach that follows from neo-liberal principles of governance, as opposed to the sustainability performance of the tourism sector. The paper then discusses the results of a survey carried out to map the extent to which Dutch tourism stakeholders would be in favor of adopting measures to improve coordination. It is concluded that, although there is support for more coordination, there is no converging vision on how specific aspects of it should be best organized. The paper highlights the need for multi-stakeholder debates that should consider the links between governance features and the sustainability performance of tourism.     

Predictive density construction and accuracy testing with multiple possibly misspecified diffusion models

This paper develops tests for comparing the accuracy of predictive densities derived from (possibly misspecified) diffusion models. In particular, we first outline a simple simulation-based framework for constructing predictive densities for one-factor and stochastic volatility models. We then construct tests that are in the spirit of Diebold and Mariano (1995) and White (2000). In order to establish the asymptotic properties of our tests, we also develop a recursive variant of the nonparametric simulated maximum likelihood estimator of Fermanian and Salanié (2004). In an empirical illustration, the predictive densities from several models of the one-month federal funds rates are compared.     

Which Governance Mechanisms Promote Efficiency in Reaching Poor Clients? Evidence from Rated Microfinance Institutions

This paper evaluates the effectiveness of several governance mechanisms on microfinance institutions' (MFI) performance. We first define performance as efficiency in reaching many poor clients. Following the literature on efficiency in banks, we estimate a stochastic cost frontier and measure output by the number of clients. Therefore, we capture the cost minimisation goal and the goal of serving many poor clients, both of which are pursued by MFIs. We next explore the impact of measurable governance mechanisms on the individual efficiency coefficients. The results show that efficiency increases with a board size of up to nine members and decreases after that. MFIs in which the CEO chairs the board and those with a larger proportion of insiders are less efficient. The evidence also suggests that donors' presence on the board is not beneficial. We do not find consistent evidence for the effect of competition, and we find weak evidence that MFIs in countries with mature regulatory environments reach fewer clients, while MFIs regulated by an independent banking authority are more efficient.     

Tourism and community resilience in the Anthropocene: accentuating temporal overtourism

Abstract

Global tourism growth is unprecedented. Consequently, this has elevated the sector as a key plank for economic development, and its utility is deeply embedded in political, economic and social-ecological discourse. Where the expansion of the sector leverages natural and cultural landscapes, this applies pressure to social and ecological underpinnings that if not reconciled, can become problematic. The way this plays out in Australia’s Shipwreck Coast and the wider Great Ocean Road region, especially the implications for community resilience, is the focus. Emphasis is placed on the vulnerability of peripheral coastal areas to development that withdraws from destination endowments, yet fails to provide commensurate economic yield as a suitable trade-off. This is obvious where tourism intensification has led to concerns about the breach of normative carrying capacities. Temporal overtourism driven by seasonal overcrowding is countenanced as emblematic of tourism in the Anthropocene where focus tends to be largely growth-oriented, with much less attention given to bolstering social-ecological resilience, especially community resilience. At stake is the resilience of regional areas and their communities, who in the absence of garnering commensurate economic returns from tourism expansion find themselves in social and ecological deficit.     

Improving the Health of Healthcare Companies

The healthcare sector has been extremely effective in improving human health while at the same time delivering outstanding returns to shareholders, at least on average. But averages can hide a lot of poor performance, and careful examination of the sector shows a sizable disparity between the long‐run productivity and value added of the top companies and the rest. To better understand the reasons for this disparity, the authors undertook a comprehensive study of how differences in capital deployment strategies, financial policies, and measures of corporate operating performance such as sales growth and return on capital are associated with returns to shareholders. Perhaps the most striking finding is the strong positive correlation in the healthcare industry between higher rates of reinvestment, especially in the form of spending on R&D and acquisitions, and stock price performance. And given the importance of such reinvestment, it is not surprising that maintaining financial flexibility by paying down net debt and otherwise limiting corporate leverage—and even issuing significant equity—are all associated with higher stock returns. When it comes to operating performance, moreover, it's not enough just to be good; it takes growth and improvement in cash flow and earnings to drive share prices higher. Measures of changes in performance such as increases in EBIT and ROIC, and high rates of growth in sales, all show consistently strong and positive relationships with stock returns while measures of levels of performance, especially EBIT margins and EBITDA margins, demonstrate relationships that are weak and in some cases even negative. Last, and consistent with the findings reported above, despite often vocal investor demands to pay dividends and buy back shares, in the case of healthcare as a whole such distributions have a clearly inverse relationship with share price performance. That is to say, the larger the payouts to shareholders, the lower the shareholder returns.     

Save the Buyback,Save Jobs

In response to a recent New York Times op‐ed by Senators Schumer and Sanders deploring the effects of stock buybacks on workers and the economy, the authors explain the role of buybacks in increasing corporate productivity and in recycling “excess capital” from mature companies with limited growth and employment opportunities to the next generation of Apples and Amazons. Some companies, as Schumer and Sanders charge, are guilty of repurchasing shares in the name of “shareholder value maximization” instead of pursuing job‐creating investments. But as the authors argue, well‐run companies increase shareholder value not by boosting EPS through buybacks, but mainly by earning competitive returns on capital and investing in their long‐run “earnings power.” And by paying out capital they have no productive uses for, such companies give their own shareholders the opportunity to reinvest in other companies with promising prospects for growth and jobs. But the authors go on to note the tendency of companies to buy back shares not when their stock prices are low, but instead when the companies are flush with cash and nearer the top than the bottom of the business cycle. The result of this tendency, as research by Fortuna Advisors (the authors' firm) shows, is that fully three quarters of companies doing large buybacks during the period 2013‐2017 failed to produce an adequate “Buyback ROI,” a metric developed by Fortuna that indicates management's effectiveness in “timing” its stock repurchases. Given the usefulness of buybacks in recycling capital, the authors conclude that the most reliable solution to the corporate short termism and underinvestment problem is for companies to adopt better financial performance measures—including Buyback ROI—to guide their capital allocation. And when management determines that it has significantly more capital than value‐adding investments, but wants to avoid committing to unsustainable dividend increases, it should consider buybacks—but only if management is convinced that its stock price has not outpaced performance.
