Abstract
This study proposes targeted modernization of the Department of Defense (DoD's) Joint Forces Ammunition Logistics information system by implementing the optimized innovative information technology open architecture design and integrating Radio Frequency Identification Device data technologies and real-time optimization and control mechanisms as the critical technology components of the solution. The innovative information technology, which pursues the focused logistics, will be deployed in 36 months at the estimated cost of $568 million in constant dollars. We estimate that the Systems, Applications, Products (SAP)-based enterprise integration solution that the Army currently pursues will cost another $1.5 billion through the year 2014; however, it is unlikely to deliver the intended technical capabilities.

Abstract
Long-term interest rates of small open economies (SOE) correlate strongly with the USA long-term rate. Can central banks in those countries decouple from the United States? An estimated Dynamic Stochastic General Equilibrium (DSGE) model for the UK (vis-á-vis the USA) establishes three structural empirical results: (1) Comovement arises due to nominal fluctuations, not through real rates or term premia; (2) the cause of comovement is the central bank of the SOE accommodating foreign inflation trends, rather than systematically curbing them; and (3) SOE may find themselves much more affected by changes in USA inflation trends than the United States itself. All three results are shown to be intuitive and backed by off-model evidence.

Abstract
Pesaran and Smith (2011) concluded that Dynamic Stochastic General Equilibrium (DSGE) models were sometimes a straitjacket which hampered the ability to match certain features of the data. In this chapter, the authors look at how one might assess the fit of these models using a variety of measures, rather than what seems to be an increasingly common device – the Marginal Data Density. The authors apply these in the context of models by Christiano, Motto, and Rostagno (2014) and Ireland (2004), finding they fail to make a match by a large margin. Both of these models feature more shocks than observed variables, resulting in the empirical shocks having a singular density, and so making them correlated. When correlated one can neither interpret impulse responses nor perform variance decompositions. Against this, there is a strong argument for having a straitjacket, as it enforces some desirable behavior on models and makes researchers think about how to account for any non-stationarity in the data. The authors illustrate this with examples drawn from the SVAR literature and also more eclectic models such as Holston, Laubach, and Williams (2017) for extracting an estimate of the real natural rate.

Abstract
Rather than organize as traditional firms, many of today’s companies organize as platforms that sit at the nexus of multiple exchange and production relationships. This chapter considers a most basic question of organization in platform contexts: the choice of boundaries. Herein, I investigate how classical economic theories of firm boundaries apply to platform-based organization and empirically study how executives made boundary choices in response to changing market and technical challenges in the early mobile computing industry (the predecessor to today’s smartphones). Rather than a strict or unavoidable tradeoff between “openness-versus-control,” most successful platform owners chose their boundaries in a way to simultaneously open-up to outside developers while maintaining coordination across the entire system.

Abstract
“Cargo tariffs are agreed through the IATA machinery, and in theory approved by governments….the IATA Tarff Coordination Conferences still agree cargo tariffs on over 200,000 separate routes. But these tariffs bear little relevance to what is actually charged in the marketplace.” (Doganis, 2002)
“The stipulations ICAO standards contain never supersede the primacy of national regulatory requirements. It is always the local, national regulations which are enforced in, and by, sovereign states, and which must be legally adhered to by air operators making use of applicable airspace and airports……ICAO is therefore not an international aviation regulator, just as INTERPOL is not an international police force. We cannot arbitrarily close or restrict a country's airspace, shut down routes, or condemn airports or airlines for poor safety performance or customer service. Should a country transgress a given international standard adopted through our organization, ICAO's function in such circumstances…….is to help countries conduct any discussions, condemnations, sanctions, etc., they may wish to pursue, consistent with the Chicago Convention and the Articles and Annexes it contains under international law.” (ICAO, 2021)
In spite of being a growing liberalized global industry served by many firms, much of the international air cargo sector operated as an admitted cartel from 1999 through 2006. Partly due to the way the cartel was discovered, it seems very little empirical analysis to date has been done about the case. We use publicly available airline data to examine whether a diligent antitrust authority could have identified cartel/collusive behavior using established empirical methods. Our findings point to a regulatory failure in an industry whose long-standing business practices effectively “slipped through the cracks,” failing to protect the many shippers of air cargo.

Abstract
Purpose – This chapter presents four different approaches to doing and writing qualitative research in strategy and management based on different epistemological foundations. It describes two well-established “templates” for doing such work, and introduces two more recent “turns” that merit greater attention.
Design/Methodology/Approach – The chapter draws on methodological texts and a detailed analysis of successful empirical exemplars from the strategy and organization literature to show how qualitative research on strategy processes can be effectively carried out and written up.
Findings – The two “templates” are based on different logics and modes of writing. The first is based on a positivist epistemology and aims to develop nomothetic theoretical propositions, while the second is interpretive and more concerned to capture and gain insight from the meanings given to organizational phenomena. The two “turns” (the practice turn and the discursive turn) are not as well defined but are generating innovative contributions based on new ways of considering the social world.
Originality/Value – The chapter should be helpful to researchers considering qualitative methods for the study of strategy processes. It contributes by comparing different approaches and by recognizing that part of the challenge of doing qualitative research lies in writing it up to communicate its insights in a credible way. Thus while describing the different methods, the chapter also draws attention to effective forms of writing. In addition, it introduces and assesses two more recent “turns” that offer promising routes to novel insight as well as having particular ontological and epistemological affinities with qualitative research methods.
