Workers of the Internet unite? Online freelancer organisation among remote gig economy workers in six Asian and African countries

This article presents findings regarding collective organisation among online freelancers in middle‐income countries. Drawing on research in Southeast Asia and Sub‐Saharan Africa, we find that the specific nature of the online freelancing labour process gives rise to a distinctive form of organisation, in which social media groups play a central role in structuring communication and unions are absent. Previous research is limited to either conventional freelancers or ‘microworkers’ who do relatively low‐skilled tasks via online labour platforms. This study uses 107 interviews and a survey of 658 freelancers who obtain work via a variety of online platforms to highlight that Internet‐based communities play a vital role in their work experiences. Internet‐based communities enable workers to support each other and share information. This, in turn, increases their security and protection. However, these communities are fragmented by nationality, occupation and platform.     

The IB/ IHRM interface: Exploring the potential of intersectional theorizing

Although the core concepts underlying IB and IHRM provide a common lexicon and epistemology, this commonality is often more implicit than explicit. We highlight not only the common ground but also the lack of critical dialogue between the two fields. This paper asks: What can each field learn from the other? What do scholars from IB learn from IHRM and vice versa? We identify a possible agenda and concerns regarding theory building as a basis for dialogue between the two fields.     

Deep hedging

We present a framework for hedging a portfolio of derivatives in the presence of market frictions such as transaction costs, liquidity constraints or risk limits using modern deep reinforcement machine learning methods. We discuss how standard reinforcement learning methods can be applied to non-linear reward structures, i.e. in our case convex risk measures. As a general contribution to the use of deep learning for stochastic processes, we also show in Section 4 that the set of constrained trading strategies used by our algorithm is large enough to ε-approximate any optimal solution. Our algorithm can be implemented efficiently even in high-dimensional situations using modern machine learning tools. Its structure does not depend on specific market dynamics, and generalizes across hedging instruments including the use of liquid derivatives. Its computational performance is largely invariant in the size of the portfolio as it depends mainly on the number of hedging instruments available. We illustrate our approach by an experiment on the S&P500 index and by showing the effect on hedging under transaction costs in a synthetic market driven by the Heston model, where we outperform the standard ‘complete-market’ solution.     

The impact of the new protectionist stance in US trade policy on selected German companies in Mexico

ABSTRACT

Previous studies on the impact of the new protectionist stance of the United States have focused mainly on the imposition of the controversial border tax. This research advances the understanding of the possible impacts of the tightening of the rules of origin and the imposition of the most-favored nation tariffs on manufacturing companies. The findings show a negative impact from the protectionist measures on businesses by increasing costs per unit and decreasing the gross margin. The results suggest that those additional costs could be passed on to the final buyers, raising the price level by more than previously assumed.     

An empirical study of third-party purchase: New Zealand users’ perspective

This article investigates the potential for third-party purchase (3PP) services offered by third-party logistics (3PL) providers, from the perspective of 3PL users, based on transaction cost analysis. We conducted a survey of New Zealand 3PL users and received 163 usable responses. Structural equation modelling was used to test the conceptual model. We found that 3PL users are more likely to adopt 3PP service when there is greater uncertainty. Asset specificity, frequency and transaction size do not have a significant relationship with 3PP service adoption. However, 3PP service is significantly related to the value-to-client and benefit-to-3PL provider. This study is pioneering research on 3PP service as a value-added service offered by 3PL providers from the perspective of 3PL users. The findings suggest that offering 3PP service will provide mutual benefits and value for both 3PL users and their 3PL providers.     

Heterogeneity in Urban Park Use of Aging Visitors: A Latent Class Analysis

This study describes and predicts urban parks use patterns for various age groups, with specific attention to the growing group of older adults. Park use intensity of various age groups is described. Subsequently, a multinomial logit model is estimated to describe urban park choice as a function of park features, activities, and socio-demographics. To identify segments in park use patterns of aging visitors a latent class model is estimated. Data are collected from a sample of 1,107 residents of the Eindhoven region in The Netherlands in 2002. The results indicate that age significantly affects park choice behavior. Specifically, four segments of older visitors were identified that clearly differed in their park use patterns: active health oriented users, active socially oriented users, passive local users, and moderate users.     

The making and remaking of HRM: the practice of managing people in the Eastern Cape Province,South Africa

This paper explores the nature of human resource management (HRM) practice in the Border region of the Eastern Cape Province, South Africa, located within contemporary local and international debates regarding the content and nature thereof. Four distinct patterns of practice were identified. The first represented a simple changing in nomenclature of the relevant personnel sections, with, in several cases, staff being seen not as managers, but rather as a distinct, and somewhat junior, category of employee. In the second category, the traditional personnel function was broadened to encompass clearly delineated areas such as training and development. In the third category, while HRM practitioners did play an important strategic role, this was more in terms of facilitating the adoption of progressive industrial relations policies, than in developing a vision for managing human resources across the organization. In all cases, what human resource practitioners did seemed somewhat removed from the 'conventional wisdom' definition of HRM. In part this was a result of the persistence of effective and militant trade unions, necessitating the adoption of hybrid HR-industrial relations practices. However, it also represented a product of particular managerial traditions, and the fact that HRM represents a complex package of concepts and practices, which, inevitably, are subject to adjustment in the light of prevailing realities. This study sheds further light on the diverse and multi-faceted area of HRM practice, and underscores the need for flexibility and pragmatism in both transitional, and, indeed, mature economic contexts.     

Market Conduct and Endogenous Lobbying: Evidence from the U.S. Mobile Telecommunications Industry

This paper empirically explores the relationship between firms' market behavior and their lobbying activities in a regulated market. In particular, we investigate whether the amount of contributions offered by cellular service providers to fund the campaigns of political parties affected market conduct in the early US mobile telecommunications industry. We structurally estimate market interactions while taking the potential endogeneity of lobbying decisions into account. Our results show that competition was more intense in those states where campaign contributions by the cellular industry have been higher. Furthermore, we reject the hypothesis that lobbying activities can be regarded as exogenous in the study of market conduct.
