Hedging of Asian options under exponential Lévy models: computation and performance

In this paper we consider the problem of hedging an arithmetic Asian option with discrete monitoring in an exponential Lévy model by deriving backward recursive integrals for the price sensitivities of the option. The procedure is applied to the analysis of the performance of the delta and delta–gamma hedges in an incomplete market; particular attention is paid to the hedging error and the impact of model error on the quality of the chosen hedging strategy. The numerical analysis shows the impact of jump risk on the hedging error of the option position, and the importance of including traded options in the hedging portfolio for the reduction of this risk.     

Eye-tracking evidence that happy faces impair verbal message comprehension: the case of health warnings in direct-to-consumer pharmaceutical television commercials

Risk warning or disclosure information in advertising is only effective in correcting consumers’ judgments if enough cognitive capacity is available to process that information. Hence, comprehension of verbal warnings in TV commercials may suffer if accompanied by positive visual elements. This research addresses this concern about cross-modality interference in the context of direct-to-consumer (DTC) pharmaceutical commercials in the United States by experimentally testing whether positive facial expressions reduce consumers’ understanding of the mandated health warning. A content analysis of a sample of DTC commercials reveals that positive facial expressions are more prevalent during the verbal warning act of the commercials than during the other acts. An eye-tracking experiment conducted with specially produced DTC commercials, which vary the valence of characters’ facial expressions during the health warning, provides evidence that happy faces reduce objective comprehension of the warning.     

How does a Change in the Excise Tax on Beer Impact Beer Retail Prices in South Africa?

This article uses price data, collected by Statistics South Africa, to estimate the effect of a change in the excise tax on the retail price of beer. We find strong evidence that the excise tax on beer is overshifted to consumers. The pass‐through coefficient is estimated at 4.83 (95% CI: 4.02; 5.64) for lager, and at 4.77 (95% CI: 4.04; 5.50) for all beer (which includes dark beer). This implies that for every R1/unit increase in the excise tax, the retail price increases by about R4.80/unit. Of the 23 brand‐packaging combinations considered, the pass‐through coefficients vary between 2.39 and 10.05 (median = 5.30). The majority of the price change in response to a tax change occurs immediately, and prices have fully adjusted two months after the excise tax increase becomes effective. Pass‐through differs substantially across packaging types. The pass‐through coefficient on 750 ml bottles is substantially lower than that of 330 ml (or 340 ml) cans and 6 × 330 ml (or 6 × 340 ml) “six‐packs.” The overshifting of the excise tax has positive implications for public health policy, since they increase the effectiveness of alcohol taxes as a tool to reduce the (excessive) consumption of beer.     

Spinoffs and clustering

Geographic clustering of innovative industries is associated with the entry and success of spinoff firms. We develop a model to explain the multiple empirical patterns regarding cluster growth and spinoff formation and performance, without relying on agglomeration externalities. Clustering naturally follows from spinoffs locating near their parents. In our model, firms grow and spinoffs form through the discovery of new submarkets based on innovation. Rapid and successful innovation creates more opportunities for spinoff entry and drives a region's growth. Our model provides baseline estimates of levels of agglomeration that can be attributed to this process of innovation and spinoff formation.     

Taking a Second Look in a Warped Crystal Ball: Explaining the Accuracy of Revised Forecasts

The fundamental questions we address are whether firms with a higher initial forecasting ability are able to accurately revise the exit forecasts of their investments; and how co‐investment partners and value‐adding commitment with their investment influence the main effect. We explore these questions with novel and unique data collected via mixed research methods on venture capital firms’ forecasts of 114 portfolio companies. We find that venture capital firms that are better at making initial forecasts are less effective in revising their forecasts. In addition, while the number of co‐investment partners positively moderate this relationship, venture capital firms’ value‐adding commitment moderates it negatively. Our findings contribute to the literature on organizational forecasting as well as inter‐organizational knowledge transfer and knowledge creation. They also provide novel insights into venture capital literature and practice.     

The effect of the 2007 ethanol mandate on downside risk in agriculture: evidence from Kansas farmers

The Energy Independence and Security Act of 2007 increased the amount of corn ethanol that must be blended into motor vehicle and other fuels as part of the renewable fuel standard. The purpose of this article is to look at how the increase in demand for corn influenced the profitability and downside risk of farms. We conducted this investigation using annual data for more than 300 farms in Kansas from 1997 through 2014. We find that the probability of a farmer’s experiencing a negative return on equity (i.e. the ‘downside risk’ of farming) decreased by 25 percentage points after 2007.     

Analysing the role of sustainable development indicators in accounting for and constructing a Sustainable Scotland

The main objective of this paper was to analyse how sustainable development indicators impacted upon the integration of sustainable development into the governing of Scotland. A major concern was whether an accounting technology could represent this complex multi-dimensional and interdisciplinary concept. We analysed the relationship between the official sustainable development strategy of the Scottish Executive and the associated indicator set using an analytics of government framework (Dean, M. (1999). Governmentality: Power and rule in modern society. London: Sage Publications. Dean, M. (2007). Governing societies. Berkshire: Open University Press). We observed a lack of alignment between these sustainable development indicators and the visions, fields of visibilities, forms of knowledge and techniques of government contained in this strategy. Critical aspects of this strategy were omitted from the indicator set and we argue that these indicators did not to effectively measure progress towards a Sustainable Scotland but that they could calculatively capture and distort the sustainable development governing process. The analytical framework used allowed us to problematise these indicators and contribute to a wider discourse on the composition and nature of sustainable development indicators.     

Postcards from the Front: Changing narratives in UK financial services

This paper seeks to explore the methodological difficulties that confront those who would seek to explain, to account for and to intervene in social affairs. Noting the predominance of ‘behaviourist’ and ‘cognitivist’ accounts of the change process and the, recent, development of ‘narrative’ alternatives we reflect upon the craft of academic writing and upon the creative choices that fabricate our worlds and our understanding. Taking the Financial Services Authority (FSA) as our example we attempt to reveal the manner in which particular authorial strategies, that remain submerged with ‘behaviourist’ and ‘cognitivist’ accounts of change, precipitate distinctive forms of policy and action in the arena of financial services. Yet we also suggest that ‘narrative’ accounts of change, which base their authority on primary research, similarly, tend to downplay the political and poetical choices that shape their elaborations because they portray ‘context’ as natural and self-evident. By revealing the authorial strategies that shape our appreciation of ‘context’ and the organized world, more generally, we hope to encourage further reflection on the application of narrative approaches, and so, further discussion of the regulation of financial services. Through such analytical processes we aim to precipitate a ‘reciprocal’ appreciation of the problems associated with accounting for the lives and experiences of others.     

FAIR Act Implications for Land Values in the Corn Belt

In 1996 the federal government enacted the Federal Agriculture Improvement and Reform (FAIR) Act, which represented a sweeping change in public policy toward agriculture. This paper examines the impact of the FAIR legislation on farmland values across the U.S. Corn Belt. A representative farm framework is used to determine the impact of FAIR on farmland values. The analysis suggests that marginal production environments are likely to suffer most severely under FAIR, and that a prolonged period of weak commodity prices could engender sharp declines in farmland values.
