A life history approach to perceptions of global climate change risk: young adults’ experiences about impacts,causes, and solutions

Although the general acceptance of human-influenced global climate change within the technical sphere of science is important to consider, public perceptions of global climate change risks, impacts, causes, and solutions are as important to policy actions as scientific findings. Yet, studies analyzing climate change risk perceptions suffer from a number of limitations or use only a handful of approaches. Using a limited life history approach, this article answers calls for additional qualitative approaches in risk perception research. This article (1) introduces risk perception researchers to the limited life history method; (2) discovers that young adults articulate climate change solutions at the individual level, often as consumers, and blend their responses to climate change risks and advocacy for solutions with a general, environmentally friendly orientation, a ‘green posture;’ and (3) contends the key sources informing young adults’ perceptions about climate change risk have changed significantly from previous studies.     

Coevolution of finite automata with errors

We use a genetic algorithm to simulate the evolution of error-prone finite automata in the repeated Prisoner’s Dilemma game. In particular, the automata are subjected to implementation and perception errors. The computational experiments examine whether and how the distribution of outcomes and genotypes of the coevolved automata change with different levels of errors. We find that the complexity of the automata is decreasing in the probability of errors. Furthermore, the prevailing structures tend to exhibit low reciprocal cooperation and low tolerance to defections as the probability of errors increases. In addition, by varying the error level, the study identifies a threshold. Below the threshold, the prevailing structures are closed-loop (history-dependent) and diverse, which impedes any inferential projections on the superiority of a particular automaton. However, at and above the threshold, the prevailing structures converge to the open-loop (history-independent) automaton Always-Defect (ALLD). Finally, we find that perception errors are more detrimental than implementation errors to the fitness of the automata. These resultsshow that the evolution of cooperative automata is considerably weaker than expected.     

Indirect tax harmonization and global public goods

This paper identifies conditions under which, starting from any tax-distorting equilibrium, destination- and origin-based indirect tax-harmonizing reforms are potentially Pareto improving in the presence of global public goods. The first condition (unrequited transfers between governments) requires that transfers are designed in such a way that the marginal valuations of the global public goods are equalized, whereas the second (conditional revenue changes) requires that the change in global tax revenues, as a consequence of tax harmonization, is consistent with the under/over-provision of global public goods relative to the (modified) Samuelson rule. Under these conditions, tax harmonization results in redistributing the gains from a reduction in global deadweight loss and any changes in global tax revenues according to the Pareto principle. And this is the case independently of the tax principle in place (destination or origin).     

Market Inertia and the Introduction of Green Products: Can Strategic Effects Justify the Porter Hypothesis?

If, according to Porter’s hypothesis, a “greener” strategy is more profitable, why may its implementation need regulatory intervention? We present a repeated Cournot duopoly where the market may exhibit inertia towards the adoption of even cost-efficient environmental goods. With consumers recognizing that a product is green only with a time lag, if a firm unilaterally adopts the green product initially loses profit due to (a) increased costs (direct effect) and (b) reduced market share (strategic effect). By imposing simultaneous adoption, regulation eliminates (b), thus enhancing long-run profitability. Through a similar mechanism a government can increase its domestic firms’ international market share and profits by forcing them to simultaneously adopt the green product.     

Wage discrimination,occupational segregation and visible minorities in Canada

The earnings gap between each of Whites, Asians, and Blacks is decomposed into the effects on earnings of productivity-related characteristics, wage discrimination and occupational segregation. Unlike previous Canadian studies, this paper analyses the relative economic position of both immigrant and native-born visible minorities and explicitly incorporates the effect of discrimination in occupational attainment on the earnings gap. The results indicate that policies aimed at increasing the ethnic representation across occupational categories would be effective only for Black men. Anti-discrimination legislation aimed at decreasing the earnings gap between visible minority and White women should have a dual focus: they should aim at reducing the inter-occupational wage discrimination; they should provide training programs to extend the career ladders confronting ethnic minority women.     

Core service versus relational benefits: what matters most?

Services literature has extensively examined the effects of core service and relational benefits on behavioral outcomes arguing that both components, studied separately, contribute significantly to customer satisfaction and loyalty. However, an integrative examination of the relative importance of both core service and relational benefits is missing. This study examines the combined impact of an extended typology of core service and relational benefits on satisfaction and relational outcomes. One qualitative and one quantitative study are conducted within a banking context. Findings confirm a more extensive typology of relational benefits and reveal that competence (part of the trust benefit) and convenience significantly affect satisfaction; however, when core service is introduced to the model, the effect of relational benefits ceases to be significant. Several future research opportunities for an integrated service benefits approach are identified; and implications for managers on how to allocate their efforts across the various types of service benefits are discussed.     

Economic restructuring and the debt problem: the Greek case

The Greek postwar economic development process clearly illustrates the links between the debt explosion, that many countries in the periphery and semi-periphery face at the moment, and the strategy of free-market economic restructuring. It is argued that both the balance of payments and the budget deficits, which fuelled the Greek debt explosion in the 1980s, have been heavily conditioned by structural problems that are directly related to the development strategy adopted by the Greek ruling élite. In the absence of radical structural changes, a new stop–go cyclical pattern tends to become a permanent feature of the development process: debt-led growth followed by Stabilization Programmes to secure the external debt servicing     

Information Asymmetry and the Bid‐Ask Spread: Evidence From the UK

Abstract:   The generally accepted factors that determine the bid‐ask spread are volatility, trading volume and market value ( Atkins and Dyl, 1997 ; Glosten and Harris, 1988 ; and Menyah and Paudyal, 2000 ). Following Kim and Verrecchia (1994) we include a measure of the disagreement in analysts' earnings forecasts in our model of the bid ask spread. This measure serves as a proxy for the informational disadvantage of market makers with respect to informed traders. Market makers respond to the additional risk by increasing the bid‐ask spread. We find that the disagreement amongst analysts is significant for horizons up to and including six months (and with the hypothesised sign) in explaining FTSE 100 company spreads, rendering strong empirical support for our model.     

A Gravity Model Forecast of the Potential Trade Effects of EU Enlargement: Lessons from 2004 and Path‐dependency in Integration

This paper uses a gravity model to forecast the potential impact on trade balances and trade patterns of the 2004 EU enlargement. The results suggest that gross trade creation for the accession economies is about 25 per cent of their 2003 trade. Although membership of the EU creates trade it also results in trade diversion; that is, a declining share of accession country exports and imports with non‐EU15 countries. Overall, the trade balances of the accession countries suffer larger trade deficits after accession due to import growth surpassing export growth. The extent of increase in the trade deficit due to accession is inversely related to the level of integration and income of the new members. Hence integration is path‐dependent and the EU should take this into account when preparing for further enlargements to the Balkans and Southeast Europe.     

On the use of labels in credence goods markets

We analyze credence goods markets in the case of two firms. Consumers know that the quality of the good varies but do not know which firm is of high quality. First, we show that the high quality producer may be unable to monopolize the market, or even to survive in some cases, in situations where it is efficient and trusted by all consumers. Second, although a label restoring full information improves welfare, it may also reduce both firms’ profits by intensifying competition. Since even the high quality producer may not wish to label its product, in such cases the label must be mandatory. Third, an imperfect label which moves everybody’s beliefs closer to the truth without restoring full information may produce adverse results on market structure and welfare, either by increasing or by reducing the variance of beliefs.
