Optimal hedging with higher moments

This study proposes a utility‐based framework for the determination of optimal hedge ratios (OHRs) that can allow for the impact of higher moments on hedging decisions. We examine the entire hyperbolic absolute risk aversion family of utilities which include quadratic, logarithmic, power, and exponential utility functions. We find that for both moderate and large spot (commodity) exposures, the performance of out‐of‐sample hedges constructed allowing for nonzero higher moments is better than the performance of the simpler OLS hedge ratio. The picture is, however, not uniform throughout our seven spot commodities as there is one instance (cotton) for which the modeling of higher moments decreases welfare out‐of‐sample relative to the simpler OLS. We support our empirical findings by a theoretical analysis of optimal hedging decisions and we uncover a novel link between OHRs and the minimax hedge ratio, that is the ratio which minimizes the largest loss of the hedged position. © 2011 Wiley Periodicals, Inc.

University of Texas Roundtable on LP Perspectives on the State of Private Equity

In this wide‐ranging discussion among four limited partner investors in private equity, the LPs commented on the rates of return they expect from PE, the fees they pay their general partners, and the length of their time commitments to PE investments. After noting the enormous growth in the value of assets under private management, and the reduction in public equity investment by many large institutional investors, each of the four LPs said that their institutions expected to maintain or continue to increase their proportion of portfolio investment in PE. The LP panelists were virtually unanimous in expecting PE rates of return in the 9%‐11% range, as compared to 7%‐8% for public equities. The panelists also seemed to agree that although committing to PE investments for terms longer than the traditional seven to ten years could result in higher returns and lower costs, they were reluctant to make such commitments because they valued the financial flexibility afforded by shorter holding periods. Several LPs claimed that their institutions were scrutinizing the explicit and implicit fees charged by the GPs, and the level of fees was encouraging LPs to co‐invest in deals alongside the GPs. And in response to a closing suggestion that the recent flurry of IPOs could signify the beginning of a major reversal away from private capital, another LP expressed strong doubt, noting that “the private ownership model has clearly shown superior governance, and greater ability to manage leveraged capital structures and create value than public companies over the long term.”     

ECONOMIC EXPERIMENTS,HYPOTHETICAL SURVEYS AND MARKET DATA STUDIES OF INSURANCE DEMAND AGAINST LOW‐PROBABILITY/HIGH‐IMPACT RISKS: A SYSTEMATIC REVIEW OF DESIGNS,THEORETICAL INSIGHTS AND DETERMINANTS OF DEMAND

This paper provides a systematic review of the literature on 80 experimental, hypothetical survey and market data studies of insurance demand against low‐probability/high‐impact risks. The objective of the review is to extract lessons from these studies and to outline an agenda for future research. We contrast the results of experimental and survey studies to findings from market data. We focus on experimental design methods, insurance characteristics, as well as results about theories, heuristics, behavioural biases and explanatory variables. Lessons for policymakers are drawn which can facilitate disaster preparedness.     

Comparative Urbanism: New Geographies and Cultures of Theorizing the Urban

In response to the growing interest in ways to take forward an agenda for a more global urban studies, this essay advocates a comparative approach to theory building which can help to develop new understandings of the expanding and diverse world of cities and urbanization processes, building theory from different contexts, resonating with a diversity of urban outcomes but being respectful of the limits of always located insights. The essay is inspired by the potential of the comparative imagination but, mindful of the limitations of formal comparative methods, which in a quasi‐scientific format can drastically restrict the scope of comparing, it outlines ways to reformat comparative methods in order to put them to work more effectively for a more global urban studies. The essay proposes a new typology for comparative methods based on the vernacular practices of urban comparison, tracing these through the archives of comparative urbanism. It also suggests some lines of philosophical reflection for reframing the scope and style of theorizing. New repertoires of comparativism are indicated which support the possibility of a revisable urban theory, starting from anywhere.     

Network brokers or hit makers? Analyzing the influence of incubation on start-up investments

Incubators are a prominent way to support technology based start-ups. Yet, it remains unclear to what extent these incubators enhance start-up performance, nor is it known through which mechanisms this would occur. In this paper we test two mechanisms to explain the relationship between incubation and the amount of investments raised by early stage start-ups as performance measure. The ‘hit maker’ mechanism refers to beneficial effects of the direct transfer of resources and organizational or business knowledge from the incubator to the start-up. The ‘network broker’ mechanism refers to the benefits that start-ups enjoy from being connected to external funding sources through the incubator’s networks. We test which of these mechanisms contribute to the performance of early stage start-ups. Our data comes from a unique survey from 935 entrepreneurs with early-stage technology based start-ups in Western Europe and North America. We find that incubators have a positive effect on (1) the amount of funding that start-ups attract and (2) the ability of start-ups to attract funding from formal investors and banks. Moreover, our results provide evidence for the network broker mechanism, but not for the hit maker mechanism.     

Sustainable Retailing – Influencing Consumer Behaviour on Food Waste

The aim of this research was to examine the influence of a UK national retailer on its customers' food waste behaviour. Using six communication channels (in‐store magazine, e‐newsletter, Facebook site, product stickers and in‐store demonstrations), Asda presented standard food waste reduction messages to its customers during two time limited periods in 2014 and 2015. Six national surveys over 21 months tracked customers' self‐reported food waste. Our results showed that the combined communication channels and repeated messages over time had a significant effect on reducing food waste of customers. Surprisingly, customers who said they did not recall seeing the messages also reduced their food waste, showing the wider influence of interventions. Those who saw a food waste reduction message saved an estimated £81 annually from reducing food waste. The main conclusion of this paper is that retailers can influence the pro‐environmental behaviour of customers using conventional communication channels; however, repeat messages are needed in order to have a long‐term impact. © 2017 The Authors.

Friendships of Virtue,Pursuit of the Moral Community,and the Ends of Business

It is argued here that business firms can and do provide an incubator that enables the Aristotelian category of friendships of advantage to develop into friendships of virtue. This contradicts other literature that views acquaintances of utility as the business norm, and expresses pessimism concerning more advanced virtuous development of friendship within the business firm. It is argued here, however, that this virtuous development is integral to the Kantian social aim of pursuing a moral community, an aim which declares the appropriate moral motivation for business, and that certainly should incorporate a role for developing virtuous relations as a component of that pursuit. An atmosphere that encourages the development of relations of virtue is feasible, exists in real business, and is optimal for pursuit of moral business communities.     

The Australian Economy in 2020–21: The COVID-19 Pandemic and Prospects for Economic Recovery

This article summarises developments in the Australian economy in 2020. It describes the economic growth and labour market ramifications associated with COVID-19, and the fiscal and monetary policies implemented to help counter its effects. COVID-19 has resulted in considerable slack in an economy that was weak pre-pandemic. While current policies are appropriately focused on stimulating demand and supporting employment, existing challenges such as weak growth in productivity, gross domestic product and real wages are also likely to remain relevant post-pandemic.
