Three bubbles and a panic: An explanatory review of recent food commodity price events

This paper is a summary of the behaviour of food commodity prices in 2007–2008 and a review of the causes of the price increases, extracted from a report to the Chief Scientific Advisor to Her Majesty’s Government [Thirtle, C., Piesse, J., 2008. An Explanatory Review of the World Food Commodity Price Events of 2007–2008. A Report to the Chief Scientific Advisor. Department for Innovation, Universities and Skills, London]. The historical background shows that the price spike was much less severe than in the 1970s. The conventional wisdom that prices of the main food commodities were falling prior to 2006 is questioned. Most ceased falling and were quite stable from the 1980s. The paper separates the causes of the spike from the underlying changes driving the long run trends. The literature on the causes of the spike is critically reviewed and summarised. There is a reasonably broad consensus on most of the causes, but much less on the impact of the depreciation of the US Dollar. There are also concluding speculations on the future.     

The Challenges of Detection and Enforcement of Insider Trading

Taking advantage of the China’s recent anti-corruption campaign, we attempt to examine the effect of public governance on a firm’s incentive to commit fraud. Using enforcement actions data from the Chinese Securities Regulatory Commission (CSRC) from 2004 to 2014, we find that, due to enhanced public governance, firms are less likely to commit fraud in the post-campaign period than in the pre-campaign period. We further show that the effect of public governance is more evident in privately held listed firms, in firms with weak legal environment, and in firms in areas with poor local economies. In addition, we find that older CEOs respond less actively to the public governance caused by anti-corruption regulations. This paper offers clear policy implications for business ethics by indicating that public governance provides external monitoring of corporate decisions.     

Competing incremental and breakthrough innovation in a model of product evolution

This paper develops a growth model in which product cycles arise endogenously from investment in incremental and breakthrough innovations. Incumbent firms invest in incremental technology improvements with the aim of reducing production costs. Market entrants develop breakthrough product designs in order to capture the market from vintage product lines. The competing objectives of the two types of innovation generate product cycles within an environment of creative destruction, as new products displace old and are then manufactured using production technologies that are continuously refined. Investigating the relationship between innovation incentives and the average length of product cycles, we characterized three stable patterns of product evolution: incremental innovation alone, breakthrough innovation alone, and product cycles with both types of innovation. Numerical examples suggest that when the market exhibits stable product cycles, subsidies to either type of innovation raise the rate of economic growth and improve welfare.     

Expressive voting and two-dimensional political competition: an application to law and order policy by New Labour in the UK

There has been much debate regarding the electoral strategy adopted by New Labour in the lead-up to and then during their time in government. This paper addresses the issue from the perspective of left/right and liberal/authoritarian considerations by examining data on individual attitudes from the British Social Attitudes survey between 1986 and 2009. The analysis indicates that New Labour’s move towards the right on economic and public policy was the main driver towards attracting new centrist voters and could thus be labelled ‘broadly’ populist. The move towards a tougher stance on law and order was more ‘narrowly’ populist in that it was used more to minimise the reduction in support from Labour’s traditional base on the left than to attract new votes. The evidence presented provides support for an expressive theory of voting in that law and order policy was arguably used to counter alienation amongst traditional, left-wing Labour supporters.

The meanings of informal and second-hand retail channels: some evidence from Leicester

Conventionally, informal and/or second-hand channels were viewed as being used by disadvantaged consumers out of economic necessity. With the cultural turn in retail and consumer research however, a new reading has emerged that views participation in such channels to be broader and more a matter of choice. To evaluate these contrasting perspectives, data collected from 120 face-to-face interviews in the English city of Leicester is reported in this article. Finding that the agency-orientated view of such retail channels is valid in affluent populations - but economic necessity remains the principal motive amongst lower-income populations - this paper reconciles these contrasting readings of economic and cultural theorists through a both/and approach sensitive to the varying meanings of such practices in different populations.     

Explaining the do-it-yourself (DIY) retail market in a developing country: preliminary lessons from India

Until now, studies of the Do-It-Yourself (DIY) market have been confined to advanced market economies, with developing countries ignored. This article begins to bridge this gap. Analysing a survey of 500 households in India, a developing country characterized by cheap and surplus labour, and a different cultural milieu, this article investigates whether it is possible to distinguish DIY consumers in the same manner as in Western nations as ‘reluctant’ or ‘willing’ DIYers. The analysis finds that in India, DIY consumers can be concurrently both willing DIYers doing so for pleasure (the choice model) or seeking self-identity from the end-product (post-modern theory) and at the same time reluctant DIYers doing so out of economic necessity reasons (economic determinism model) or due to the lack of appropriately skilled labour (a market failure model). Results also reflected cultural connotations to the respondent perceptions. The multiplicity of reasons, in consequence, shows that no one theorisation of DIY consumers' motives is universally relevant but all theories are sometimes valid. As such, a new typology of DIY consumers' motives has been inductively generated which is theoretically integrative. The results conclude on the need to move beyond using one theory and treating the others as rival competing theories, for a comprehensive explanation of DIY.
