High-frequency trading,algorithmic finance and the Flash Crash: reflections on eventalization

The Flash Crash of 6 May 2010 has an interesting status in discussions of high-frequency trading, i.e. fully automated, superfast computerized trading: it is invoked both as an important illustration of how this field of algorithmic trading operates and, more often, as an example of how fully automated trading algorithms are prone to run amok in unanticipated frenzy. In this paper, I discuss how and why the Flash Crash is being invoked as a significant event in debates about high-frequency trading and algo-financial markets. I analyse the mediatization of the event, as well as the variety of eventalizations of the Flash Crash - the different ways in which the Flash Crash is being mobilized as an illustrative event. I critically discuss the impact often associated with the Flash Crash – and on that basis, inquire into why the event nonetheless attracts so much attention. I suggest that a key reason why the Flash Crash is widely discussed is that eventalizations of 6 May 2010 evoke familiar tropes about the fear of technology and the fear of herding. Finally, and given their emphasis on herding, I argue that the Flash Crash eventalizations may contribute to discussions within economic sociology about resonance in quantitative finance.     

China’s Phantom Urbanisation and the Pathology of Ghost Cities

This article examines the production of China’s “ghost cities” and constant urban expansion to challenge the dominant conceptual narrative of rural-to-urban migration as the driver of urbanisation. It argues that behind China’s “miraculous” urbanisation story is a powerful ideological commitment to urban growth as the “royal road” to modernity and assessment of political performance. Local governments have a wide-ranging “tool-kit” for pursuing urbanisation, ranging from administrative border-drawing to expropriation of rural land and investment in expanding urban infrastructures. Urbanisation is the destination to which all paths seem to lead. Indeed, local states pursue the construction of new urban space, even when doing so harms them financially. But why? The concept of phantom urbanisation names the process whereby constructing the aesthetic form of the urban is even more important to local state actors than economic, demographic or environmental repercussions.     

Procompetitive dual pricing

We analyze the procompetitive effects of dual pricing, that is, input market price discrimination. An upstream firm has an incentive to maintain competition downstream which is realized by selling at an advantageous price to an inefficient downstream firm when discrimination is possible while it would exit under uniform pricing. We augment the exit issue into existing frameworks of Katz (Am Econ Rev 77:154–167, 1987), DeGraba (Am Econ Rev 80:1246–1253, 1990), and Yoshida (Am Econ Rev 90:240–246, 2000) which allows us to show that price discrimination in intermediary goods markets tends to have positive effects on allocative, dynamic and productive efficiency, respectively. In contrast, a discrimination ban tends to facilitate exit of relatively inefficient firms, thereby strengthening downstream market concentration.     

Elite interests and political participation in Botswana, 1966–2014

ABSTRACT

Botswana’s tiny economy is overwhelmingly government-driven and political participation, particularly on the side of the ruling party, is critical for one’s economic survival and prosperity. This has led to enduring intrigue and conflict among the country’s political power elite. Opposition party activists traditionally have embraced leftist policies and claimed to be representing the country’s poor and downtrodden while castigating the ruling Botswana Democratic Party (in power since 1966) of being pro-rich and politically connected business. Ironically, some members of the opposition elite also engage in business ventures with their ruling party counterparts. The scramble for economic opportunities has fuelled debilitating factionalism within both the ruling and opposition parties over the years. In some instances tribalism was mobilised in intra- and inter-party elections for positions of influence even though voters are more interested in service delivery than traditional ethnic issues. Our paper considers the question: ‘Whose interests do Botswana’s politicians represent?’     

Risky business? Evaluating market risk of equity investment proposals to reform social security

A number of options have been proposed to address the expected financing shortfall of Social Security in the next century. Most basic aspects of the various reform proposals are captured by the three options offered by the Advisory Council on Social Security in 1996. Common to all three options is that they would permit either public or private equity investment. This article discusses the economic risks involved in public and private equity investments as a funding solution for Social Security. To quantify the risks involved in equity investment, stochastic simulations are based on the economic assumptions of the 1998 Trustees Report of Old Age and Survivors Insurance and Disability Insurance in combination with different assumptions about the rates of return on bonds and stocks. For public equity investment, financial market risk remains significant for at least 40 years. For individual accounts, I find that the chance of doing worse than with Social Security or of falling into poverty in retirement is generally high, yet varies with income level, gender, family status, and employment history. In general, women, married workers with dependent spouses, or workers with incomplete work histories fare worse than men, single workers, or workers with complete work histories when compared either to the current system or to the poverty line. © 2000 by the Association for Public Policy and Management.     

How does social trust lead to better governance? An attempt to separate electoral and bureaucratic mechanisms

This paper explores questions related to the association between social trust and governance. In particular, the paper explores whether the trust-governance association is mainly a reflection of political responsiveness to the demands of the electorate or of the supply of honest politicians and bureaucrats. After outlining some simple theory, the findings suggest that the association reflects a causal influence of both types of trust on institutions of economic-judicial governance while electoral institutions are not associated with social trust. Assessed at the sample mean, the value of social trust under high political competition as evaluated by the compensating income variation is substantial.     

Bone Area Histomorphometry

Quantifying the amount of cortical bone loss is one variable used in histological methods of adult age estimation. Measurements of cortical area tend to be subjective and additional information regarding bone loss is not captured considering cancellous bone is disregarded. We describe whether measuring bone area (cancellous + cortical area) rather than cortical area may improve histological age estimation for the sixth rib. Mid‐shaft rib cross‐sections (n = 114) with a skewed sex distribution were analyzed. Ages range from 16 to 87 years. Variables included: total cross‐sectional area, cortical area, bone area, relative bone area, relative cortical area, and endosteal area. Males have larger mean total cross‐sectional area, bone area, and cortical area than females. Females display a larger mean endosteal area and greater mean relative measure values. Relative bone area significantly correlates with age. The relative bone area variable will provide researchers with a less subjective and more accurate measure than cortical area.

“A different world” exploring and understanding the climate of a recently re-rolled sexual offender prison

Understanding how sexual offenders experience prison and its environment is important because such experiences can impact on rehabilitation outcomes. The purpose of this research investigation was to explore the rehabilitative and therapeutic climate of a recently re-rolled sexual offender prison. The research took a mixed methods approach and consisted of quantitative and qualitative phases. There were differences between prisoners and staff on their perception of the prison climate and for prisoner and staff relationships. The qualitative results helped to explain the quantitative findings and added a more nuanced understanding of the experience of the prison, the nature of prisoner and staff relationships and the opportunities for personal growth within the prison. The study has important implications for prisons that co-locate sexual offenders and want to provide an environment conducive to rehabilitation.
