Food Price Pass‐Through and the Role of Domestic Margin Services

The recent volatility in international agricultural markets has drawn attention to the impact of rising international agricultural prices and the induced price‐insulating measures on consumer food prices. Analyses based on simulation models on this topic typically ignore the role of domestic margin services. We extend the standard Global Trade Analysis Project (GTAP) model to allow for variations in the share of domestic margin services in consumed food across countries. This approach enables us to differentiate consumer prices from producer prices. Following the extension, the results show that domestic margin services reduce the consumer food price volatility for all countries, especially in high‐income countries, where the share of domestic margin services in final food consumption is higher. The effect of price‐insulating border policies is also reduced in the extended model. We find that our extension of the GTAP model greatly improves simulations of the 2007 surge in international agricultural prices. We validate our extension of the GTAP model by showing that the econometrically estimated food price pass‐through is decreasing with income and thus, is smaller in high‐income countries.     

Normfare: Norm entrepreneurship in internet governance

This special issue is the first to systematically address the activity we call “normfare” - the assiduous development of norms of very different character (public and private, formal and informal, technically mediated and directly implemented) by different actors (platforms, standard-setters, states) as an answer to the wide range of challenges facing internet governance. We bring together contributions from leading anthropologists, technologists, political scientists, legal and communication scholars exploring how norms underpin the new ordering of the internet, whether in explicit or implicit forms. Through various theoretical lenses, contributions analyze the impact of platforms, states, civil society, expert groups and key individuals on restructuring the normative order of the internet, and present empirical evidence for instances of norm creation, legitimation, contestation and opposition. Valuable new insights for norm development processes come from case studies, ethnographies, legal and discourse analysis and interdisciplinary approaches locating agency and power plays. In this introduction, we define the key concepts applicable to norm entrepreneurship and discuss their interplay in internet governance debates, followed by an overview of the articles included in the special issue. In the final section, we reflect on the implications of our new research agenda.     

University patenting and technology commercialization – legal frameworks and the importance of local practice

The impact of national legislative frameworks on the higher education sector's contribution to technological innovation is heavily disputed. This paper argues that legislative frameworks may stimulate the development of local practices for the management and exploitation of intellectual property (IP), which in turn determine the level of academic patenting. We present case studies of two comparable universities in each of four selected European countries with different histories of national IP legislation. A within-country analysis shows that a wider range and earlier development of local IP management and exploitation practices are accompanied by higher levels of academic patenting, and that increasing similarity of IP practices is associated with decreasing differences in patenting outputs. A preliminary cross-country analysis reveals an expansion in and increasing similarity of practices for IP management and exploitation in countries with different national IP framework histories. We conclude that adopting Bayh-Dole-like legislation may trigger the development of local IP practices, which stimulate patenting. However, it is not always sufficient and definitely not always necessary. The study concludes with some policy recommendations.     

Justifying Public Sector Accounting Change from the Inside: Ex-post Reflections from Three Countries

Looking at accounting reforms in central government, the paper investigates how key actors (senior managers responsible for developing and/or implementing change) account for the related change outcomes subsequent to implementation. Using aggregated data from three countries (the UK, Italy, and Austria), and a mixed-methods approach, the study investigates which rhetorical strategies are used to construct ex-post legitimation or delegitimation of the changes, and how these strategies are associated with different perceived outcomes of change. Building on previous literature, possible strategies for ex-post (de-)legitimation and outcomes of change are identified. The study finds that radical change (leading to new accounting systems bedding down with accompanying new interpretative schemes) is associated with ex-post legitimation based on rationalization. In contrast, incremental change (introducing new accounting tools, but not resulting in changed interpretative schemes) is often connected with narratives criticizing (or delegitimating) the change. The study contributes to the scant body of literature focusing on ex-post legitimation of accounting change. How managers justify change in relation to its outcomes provides useful insights for the current situation when, as a consequence of crisis and austerity, new roles and relevancies for accounting and control systems continue to emerge. It is argued that for change to be substantive, it is not only essential that the actual systems and structures of accounting are adjusted, but it is critical that the way people interpret and make sense of accounting information (and consequently take decisions) is also modified. The particular challenges of achieving this in a period of crisis are highlighted.

(Un)skilled leveraged trading of retail investors

We study the trading behavior of retail investors in the market of leveraged bank-issued retail derivatives, which are designed to encourage excessive trading and speculation. We investigate whether retail investors have private information and benefit disproportionately or whether they gamble without private information. We answer this question along three dimensions: (i) profitability, (ii) news trading, and (iii) transaction costs. We distinguish between derivatives by the type of underlying (index vs. individual stocks). We find that raw returns are negative for derivatives with stocks as the underlying, and only partially positive for those with index as the underlying. Nevertheless, risk-adjusted returns show poor performance, with Sharpe ratios below 0.30. We show that retail investors are attracted by news, but do not have private information prior to news events.     

Constraint-based ACO for a shared resource constrained scheduling problem

We consider a scheduling problem arising in the mining industry. Ore from several mining sites must be transferred to ports to be loaded on ships in a timely manner. In doing so, several constraints must be met which involve transporting the ore and deadlines. These deadlines are two-fold: there is a preferred deadline by which the ships should be loaded and there is a final deadline by which time the ships must be loaded. Corresponding to the two types of deadlines, each task is associated with a soft and hard due time. The objective is to minimize the cumulative tardiness, measured using the soft due times, across all tasks. This problem can be formulated as a resource constrained job scheduling problem where several tasks must be scheduled on multiple machines satisfying precedence and resource constraints and an objective to minimize total weighted tardiness. For this problem we present hybrids of ant colony optimization, Beam search and constraint programming. These algorithms have previously shown to be effective on similar tightly-constrained combinatorial optimization problems. We show that the hybrid involving all three algorithms provides the best solutions, particularly with respect to feasibility. We also investigate alternative estimates for guiding the Beam search component of our algorithms and show that stochastic sampling is the most effective.
