The purpose of this paper is to provide an economic analysis of the sources of supply to the US shrimp market.

The paper uses monthly time series data to estimate a simultaneous equations model with equations for domestic supplies from the Gulf of Mexico, imports, and prices.

Estimated long-run elasticities suggest that the domestic shrimp supply appears to be explained by seasons, diesel fuel price, hurricane activity, and shrimp price. The authors find evidence of a downward-slopping supply curve for the domestic harvesters that is likely to be temporary. Furthermore, anti-dumping duties have been ineffectual in curtailing imports produced by exploitation of natural shrimp biomass in developing countries and by technological advancements in aquaculture production. The authors also find evidence of a low exchange rate pass through. Finally, while domestic and import prices are not cointegrated, there is a two-way causality between them.

The authors found evidence that shrimp prices have fallen as import supply, due to technological advances in aquaculture, has risen faster than the US domestic demand over time suggesting a downward sloping supply curve. Also, the falling value of the US dollar has discouraged the imports, while the anti-dumping duties appear to have had little influence on the aggregate level of imports.

It provides a thorough investigation of the supply side of an important component of the US seafood market displaying the complexity of domestic producers’ reaction to falling prices, and ineffectual protectionism.

Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.

Resurgent interest in the life and work of the Italian Cambridge economist Piero Sraffa is leading to New Directions in Sraffa Scholarship. This chapter introduces readers to some of these developments. First and perhaps foremost is the fact that as of September 2016 Sraffa’s archival material has been uploaded onto the website of the Wren Library, Trinity College, Cambridge University, as digital colour images; this chapter introduces readers to the history of these events. This history provides sharp relief on the extant debates over the role of the archival material in leading to the final publication of Production of Commodities by Means of Commodities, and readers are provided a brief sketch of these matters. The varied nature of Sraffa scholarship is demonstrated by the different aspects of Sraffa’s intellectual legacy which are developed and discussed in the various entries of our Symposium. The conclusion is reached that we are on the cusp of an exciting phase change of tremendous potential in Sraffa scholarship.

Advances in Econometrics is a series of research volumes first published in 1982 by JAI Press. The authors present an update to the history of the Advances in Econometrics series. The initial history, published in 2012 for the 30th Anniversary Volume, describes key events in the history of the series and provides information about key authors and contributors to Advances in Econometrics. The authors update the original history and discuss significant changes that have occurred since 2012. These changes include the addition of five new Senior Co-Editors, seven new AIE Fellows, an expansion of the AIE conferences throughout the United States and abroad, and the increase in the number of citations for the series from 7,473 in 2012 to over 25,000 by 2022.

Market-based approaches to environmental management are increasingly common. In 1983 when Joeres and David published their pioneering collection, Buying a Better Environment, the concept was seen as at best novel, and at worst far-fetched. Yet today, conservation and water quality credits are for sale in many developed countries, and the idea of payment for ecosystem services is ubiquitous in environmental policy circles. This paper traces that shift from command-and-control to market-based environmental management through analysis of the evolving practice of stream mitigation banking (SMB) in the US. In the most common form of SMB today, a for-profit company buys land with a damaged stream on it and restores it to produce mitigation credits which can then be purchased by developers to fulfill their permit conditions under the Clean Water Act. Though decidedly noncommercial in origin, SMB was converted into for-profit tradable regulatory mechanism in 2000 and has since spread rapidly across the US with the strong support of the US Environmental Protection Agency. Using Bourdieu’s field concept as a framework, I argue that the neoliberal transformation of mitigation banking is a product of both relations within the regulatory field, of that field’s relations with the fields of science, and of power.

This essay explores certain aspects of single product industry basic systems of the type Sraffa develops in Part I of Production of Commodities by Means of Commodities. It focusses on triangular trade as the simplest expression of the more general n-commodity case. Two elements of the framework are explored: (i) the relation of exchange between all commodities, conceived as the configuration of exchange which is applicable to the subsistence and surplus models, and (ii) the value/price expressions of labour time, applicable to the surplus model only, which posits the productivity of, remuneration to and extraction from living labour added to the system. This analysis complements and extends the Marxian reading of Sraffa’s notions of surplus and deficit industries first explored in Carter (2014b). The methodology of ‘given quantities’ in expositing the relations developed is adopted in this essay as it corresponds to the same method employed by Sraffa. This allows readers to easily move from the present essay to Sraffa’s book and importantly his archival notes which are now for all interested parties available as colour digital images on the Wren Library website.

It has often been said that a great part of the strength of Aslib lies in the fact that it brings together those whose experience has been gained in many widely differing fields but who have a common interest in the means by which information may be collected and disseminated to the greatest advantage. Lists of its members have, therefore, a more than ordinary value since they present, in miniature, a cross‐section of institutions and individuals who share this special interest.

This paper aims to examine the antecedents of customer inertia (i.e. knowledge, confusion, perceptions of competitor similarity and switching costs) and their relationship to customer satisfaction, service providers’ switching intentions and actual switching behavior. Customer inertia is said to reduce the incidence of service provider switching; however, little is known about the antecedent drivers of inertia.

The conceptual model was tested by a longitudinal/discontinuous panel design using an online survey research of 1055 adult (i.e. +18 years old) subscribers to cell phone services. Partial least squares (PLS) path modeling was used to simultaneously estimate both the measurement and structural components of the model to determine the nature of the relationships between the variables.

Findings of the PLS structural model provide support for the direct relationship between customer inertia and its antecedents (i.e. knowledge, confusion, perceptions of competitor similarity and switching costs). The results show that customer inertia has a moderate negative effect on the intention to change service providers but had no measurable effect on the actual behavior of changing service providers, other than indirectly, by influencing the perception of difficulty in switching some 11 months later. Further results from an analysis of indirect pathways of the antecedents to inertia show that switching costs are the only variable which indirectly reduce intentions to change service providers. The results also show that the effect of satisfaction on switching service providers is partially moderated by inertia. Importantly, these relationships are reasonably robust given past switching behavior and contract status of consumers.

The authors find evidence which explains some of the causes of inertia, and show that it has both direct and moderating effects on service provider switching intentions, though not necessarily the behavior of changing service providers. However, support was found for its indirect role through intent as an influence on switching behavior. Importantly, the authors find that inertia has lingering effects, in that it influences the perception of switching difficulties and, hence, behavior up to 11 months in the future.

Managerial implications are that service firms can profit from customer inertia through a reduction in churn. However, high levels of customer inertia over the longer term may increase the level of customer vulnerability to competitor offers and marketing activities, as satisfaction with the provider does not in itself explain switching intentions or behavior.

This study is the first study to contribute to an understanding of the antecedent drivers of customer inertia with respect to service provider switching and to empirically evaluate a variety of antecedent factors that potentially affect switching intentions. Importantly, the long lasting latent effect of inertia in indirectly influencing service switching behavior was found to persist some 11 months later.

This chapter provides evidence that the Stonewall Inn riots were the foundation for a legacy of empowerment and improvements in the civil and political rights of the Lesbian, Gay, Bisexual, and Transgender (LGBT) community in the United States. Increased protections in the United States and globally are needed to fully integrate LGBT individuals into society. The next phase of this work will examine how the failure to extend equitable civil and political rights to LGBT individuals has led to continued stigma and discrimination which, in turn, is associated with a host of LGBT health disparities ranging from HIV to suicide to substance use. Future research will also identify ways to reduce these inequities.
