The interface between growth,trade, pollution and natural resource use in Chile: evidence from an economy wide model

We investigate the implications of trade liberalization and pollution taxes on aggregate income, pollution, and natural resource use in Chile with a neoclassical economywide model comprising 75 sectors. The model incorporates 13 measures of pollution effluents which are linked to the use of polluting inputs and energy use. We estimate the economic and environmental impact of Chile's participation in NAFTA, MERCOSUR, of unilateral trade liberalization and effluent taxes. Unilateral trade liberalization induces substantial worsening of pollution emissions and expansion of resource-based sectors, partly because of access to cheaper energy. NAFTA integration is environmentally benign in terms of pollution emissions.     

Boundaryless careers in the gig economy: An oxymoron?

Advocates of the boundaryless career perspective have relied to a great extent on the assumption that actors take responsibility for their own career development and that they consequently take charge of developing their career competencies. In this provocation piece, we debate the obstructions to and potential ways to promote boundaryless careers in the gig economy, which—despite appearing on the surface to offer suitable conditions for boundaryless careers—suffers from numerous conditions that hinder such careers. Thus, boundaryless careers in the gig economy could be an oxymoron. In particular, we conjecture that intraorganisational and interorganisational career boundaries restrict gig workers' development of relevant career competencies and thus limit their mobility. We then put forward the notion that we have to consider moving away from traditional, employer‐centric human resource management and introduce new forms of network‐based and self‐organised human resource management practices (in the form of collaborative communities of practice) in order to diminish these boundaries.     

Tracing the Pathways from Research to Innovation: Evidence from Case Studies

The complex process through which agricultural research stimulates innovation and achieves policy goals has commonly been treated as a ‘black box’ in the scientific literature. Statistical correlations between measured expenditure and impacts, where satisfactorily established, have mostly led to details of the research and innovation system being ignored. However, identifying and exploring causal chains of impact propagation can strengthen agricultural innovation. IMPRESA investigated impact mechanisms for research‐based innovations in six case studies using a Participatory Impact Pathway Assessment approach. Several suggestions result for improving performance and public support for agricultural research. Planning for impact is needed at the design phase of research so that expected advances in technology and their consequences can be explored. At that stage and throughout the research process, soft social skills are required to promote uptake. Greater impact can be achieved through the close involvement of key public and private sector stakeholders, using stakeholder mapping as a supporting tool. There is a strong argument for the close involvement of relevant social scientists and professional facilitators from the design phase of research through to its ultimate impacts. Funding frameworks and the specification of calls for tenders would function more effectively by giving more flexibility for stakeholder engagement.     

Expected utility and the siegel paradox: A generalization

It was recently shown by Sinn that, under certain conditions, because of the Siegel paradox, even risk-averse agents can find speculation on forward currency markets attractive. His assumptions are that the spot and forward rates are identically distributed and statistically independent and that the agents' coefficients of relative risk aversion are constant and inferior to unity. We show that both assumptions of statistical independence and constant relative risk aversion can be dramatically relaxed.Thanks are due to H.-W. Sinn, W. T.

Repertoire of strategies used by French Canadian mothers living in Montreal to pressure their 10‐year‐old children to eat

This study is concerned with mothers’ use of strategies directed toward their 10‐year‐old children to pressure them to eat. The objective is to document the repertoire of strategies and their context of use. This child‐feeding practice is of interest because of its impact on the child's opportunities for the development of self‐control based on responsiveness to hunger and satiety cues. A total of 24 interviews and one focus group were conducted with French Canadian mothers. Data analyses reveal four major themes associated with the contexts in which pressure to eat were used: food purchasing, food preparation, meal service, food consumption. Strategies related to the context of food purchasing stress the importance of children's influence on family decisions. The strategies used at the time of preparation of meals illustrate the burden of tasks a mother takes on to ensure that her child consumes a particular food. With regard to meal service, very few strategies take into account the appetite of the child. Finally, the variety of strategies deployed at the time of consumption of foods supports the importance of informing parents of the undesirable effect of techniques associated with forcing the child to eat. Avenues for future research are presented.     

The Information Content of Short Selling Around Close Supply Chain Relationships

Close supply chain relationships are sometimes detrimental to the partnering firms, and short sellers recognize this before the rest of the market. Suppliers and customers that are in linked, close supply chain relationships have higher short interest on average. Further, higher short interest increases the likelihood of large, linked customers reporting negative earnings surprises, whereas suppliers with high short interest are more likely to report negative earnings surprises, irrespective of the supply chain structure. Short selling is informative to capital markets because these suboptimal relationships eventually lead to dependent suppliers being delisted from a stock exchange for financial distress reasons.     

The dynamic implications of increasing returns: Technological change and path dependent inefficiency

This paper addresses the issue of path-dependent selection and inefficiency, counterfactual methods and the empirical evidence employed in this research trajectory. The general message is basically that the theoretical argument to prove path-dependent inefficiency is relatively straightforward, while empirical demonstrations, as well as the analysis of welfare implications are much more difficult. In the first section, we briefly state the basic argument explaining how localized learning leads to an incomplete exploration of the variety distribution of a technology. We then synthesize the most interesting historical studies, which get potential regret results, and ask whether these results suggest a large welfare loss. To try to answer this question, we start from the critical arguments of Liebowitz and Margolis to discuss the theoretical and empirical difficulties of establishing path-dependent inefficiency.     

The Dynamics of Insurance Prices

We develop a continuous-time general-equilibrium model to rationalise the dynamics of insurance prices in a competitive insurance market with financial frictions. Insurance companies choose underwriting and financing policies to maximise shareholder value. The equilibrium price dynamics are explicit, which allows simple numerical simulations and generates testable implications. In particular, we find that the equilibrium price of insurance is (weakly) predictable and the insurance sector always realises positive expected profits. Moreover, rather than true cycles, insurance prices exhibit asymmetric reversals caused by the reflection of the aggregate capacity process at the dividend and recapitalisation boundaries.
