Who should sell stocks?

Never selling stocks is optimal for investors with a long horizon and a realistic range of preference and market parameters, if relative risk aversion, investment opportunities, proportional transaction costs, and dividend yields are constant. Such investors should buy stocks when their portfolio weight is too low and otherwise hold them, letting dividends rebalance to cash over time rather than selling. With capital gains taxes, this policy outperforms both static buy‐and‐hold and dynamic rebalancing strategies that account for transaction costs. Selling stocks becomes optimal if either their target weight is low or intermediate consumption is substantial.     

Labor Market Dynamics: A Time‐Varying Analysis

This paper studies how key labour market stylized facts and the responses of labour market variables to technology shocks vary over the US postwar period. It uses a benchmark dynamic, stochastic, general equilibrium model enriched with labour market frictions and investment‐specific technological progress that enables a novel identification scheme based on sign restrictions on a SVAR with time‐varying coefficients and stochastic volatility. Key findings are: (i) the volatility in job finding and separation rates has declined over time, while their correlation varies across time; (ii) the job finding rate plays an important role for unemployment, and the two series are strongly negatively correlated over the sample period; (iii) the magnitude of the response of labour market variables to technology shocks varies across the sample period.     

How an international ambidexterity strategy can address the paradox perspective on corporate sustainability: Evidence from Chinese emerging market multinationals

Corporate sustainability (CS) is receiving considerable attention from emerging market multinational enterprises (EMNEs), playing an important role in the globalized market. However, theoretical and empirical knowledge about how EMNEs address CS is still scant, and the relationship between internationalization and CS has not been widely explored. This study aims to fill this gap, evaluating the relationship between an international ambidexterity strategy and CS in EMNEs, which highlighted the paradox perspective. Then we develop three hypotheses in which we argue how the dynamic capabilities underpinning international ambidexterity could be considered a driver of CS in EMNEs. We test the developed hypotheses against data from 300 Chinese EMNEs obtained by a survey. Our results contribute to shape ambidextrous international strategies and to consider CS as a springboard for the strategic intent to systematically and recursively outperform global competition. Testing a measurement scale of international ambidexterity, we suggest structural ambidexterity as a strategic option of internationalization that allows the achievement of economic, social, and environmental sustainability objectives.     

Which factors hinder the adoption of open innovation in SMEs?

The literature on open innovation (OI) is characterised by studies based both on large companies and small and medium-sized enterprises (SMEs). Among all, one of the less explored issues in SMEs is what impedes them to adopt OI. Thus, this paper has the threefold objective to identify which factors hinder the adoption of OI in SMEs, to investigate if different behaviours exist among SMEs in relation to these factors, and to understand if the same factors effectively influence the level of adoption of OI. Based on a survey on 157 Italian SMEs, we identified four main barriers (namely, ‘knowledge’, ‘collaboration’, ‘organisational’, and ‘financial and strategic’) and three profiles of firms, different in terms of innovativeness of the industries they belong to (knowledge intensive, medium-innovative, and less innovative) and hampering factors perceived (‘knowledge’, ‘financial and strategic’, and ‘collaboration’ and ‘organisational’ barriers). Moreover, we found that some of these factors effectively impede the adoption of the paradigm.     

CO‐INTEGRATING VAR MODELS AND ECONOMIC POLICY

This paper surveys some relevant contributions to the economic literature on co‐integrating vector autoregressive (VAR) models [vector error correction mechanisms (VECMs)], emphasizing their usefulness for economic policy. It further discusses some theoretical aspects that are necessary for a complete understanding of their potential. The theoretical introduction of the co‐integrating VAR model is followed by an illustration of its applications to monetary policy, fiscal policy and exchanges rates as well as in establishing the effects of structural bilateral shocks between countries (the so‐called global VAR, or GVAR, models). Special attention is paid to the VECM capacities of being used in conjunction with dynamic stochastic general equilibrium models and of jointly specifying the short‐ and long‐run dynamics, thus representing the steady‐state of economic systems (by means of the co‐integration relations) and the short‐run dynamics around it.     

Mapping the antecedents of telework diffusion: firm‐level evidence from Italy

Previous literature has studied telework practices predominantly from the employees' perspective rather than exploring its use at the firm level. With the objective of contributing to reducing this research gap, the relationship between firms' adoption of telework and the firms' technological, organisational and environmental contexts is explored. Data were obtained from a survey conducted between 2005 and 2009 on a sample of 1,134 Italian firms in the Piedmont region. The results show an overall increase in the diffusion of telework primarily attributable to a rise in the adoption of ‘mobile’ work rather than home‐based forms of telework. The results also show that firms that had previously adopted information systems supporting core business processes and knowledge management were more inclined to adopt telework. Telework arrangements were more widely diffused among firms facing a growing and geographically dispersed market demand, and also in the contexts of higher levels of human capital and lower capital intensity.     

Limits to creative destruction and technologies in practice: the case of ham radio

Drawing on the structurationist notion of ‘technologies-in-practice’, this article analyses the different types of technological actions that users perform, after technological change, in order to keep a declining technology alive over time. The research question of the article is: How do technologies-in-practice based on the application of new technology hamper the creative destruction of old technology? The case study of ham radio technology and amateur radio operators is explored. The results of the investigation support the development of a technology-in-practice ‘experimentation’ and four inductive research propositions.     

CSR in SMEs: do SMEs matter for the CSR agenda?

In this paper we argue that the collective grandness of small business is often underestimated in CSR research and policy-making. We emphasize the importance of understanding the contexts and the ways in which small- and medium-sized companies engage in CSR and how they differ from multinational companies. We suggest that it might be that researchers and practitioners are asking the wrong questions in their ambitions to prove 'the business case for CSR'. Perhaps we should rather focus on the 'how' and the 'with what impact' questions to understand better the SME engagement in CSR.
